Specific embodiment
It please join Fig. 1, present embodiment discloses a kind of desk-top sweep-saw 100, which includes workbench
110 and the cover assembly 120 that is arranged on workbench 110.Workbench 110 has the upper surface 111 for carrying workpiece.Shield
Shade assembly 120 is equipped with the pressing piece 130 being oppositely disposed with workbench 110.Pressing piece 130 is equipped with elastic deformation ability
Flexible elastomer 131.When above-mentioned pressing piece 130 is pressed on workpiece, 131 compressive deformation of flexible elastomer, elasticity thereon
Restoring force acts on workpiece, so as to the pressing that consolidates workpiece on the table.Be provided on cover assembly it is above-mentioned by
Casting die 130, since pressing piece 130 is equipped with the flexible elastomer with elastic deformation ability, it is thus possible to will have rough surface
Workpiece be smoothly pressed against on workbench 110, and workpiece can be made not generate vibration in cutting process, and then improve work
The machining accuracy of part.
Further, cover assembly 120 includes the boot main body 121 being connected with above-mentioned pressing piece 130 and workbench 110
It fixed shield stand 122 and is connected with boot main body 121 and the pivotal arm 123 in shield stand 122 can be pivoted.
By driving pivotal arm 123 that boot main body 121 can be made to be in close to the first operating position of workbench 110 and away from workbench
110 the second operating position.When boot main body 121 is in the first operating position, desk-top sweep-saw 100 is in cutting workpiece
Working condition in this case, increases, pressing piece 130 can progressively abut on the surface of the workpiece with the feed distance of workpiece；When
When boot main body 121 is in the second operating position, desk-top sweep-saw 100 is in off working state, in this case, operating personnel
Easily saw blade can be replaced.In addition, during boot main body 121 is additionally included in workpiece feeding, for compressing work
The pressing plate 1211 of part, is disposed adjacent between pressing plate 1211 and pressing piece 130.
In addition, manufacture is integrally formed between boot main body 121 and pressing piece 130, it should be pointed out that in other embodiment party
In formula, it can also pass through guide groove by being fixedly connected between card slot and buckle between boot main body 121 and pressing piece 130
Removably be connected between guide rail, further, it is also possible in other manners come realize boot main body 121 and pressing piece 130 it
Between connection fix, be not specifically limited herein.
It please join Fig. 2 to Fig. 5, flexible elastomer is arranged in M N array, wherein, M is the positive integer more than or equal to 1, and N is also
Positive integer more than or equal to 1.In addition, the flexible elastomer can be flexible sheets either flexible column or flexible sheets and flexible column
Combination.The material of flexible elastomer can be plastic material, it should be pointed out that in other embodiments, flexible pellet
Property body material can also be rubber material, the material of flexible elastomer is not specifically limited, as long as disclosure satisfy that it is compressed
Corresponding function with the elastic restoring force deformed towards workpiece when on workpiece.
It please join Fig. 2, be the sectional view of pressing piece embodiment 1 at A-A in Fig. 1, it was found from sectional view, present embodiment
The flexible elastomer 131 of 1 × 12 and longitudinal array arrangement is provided on pressing piece 130, which is flexible sheets.
Wherein, the width of pressing piece 130 is advisable with similar to the width of pressing plate 1211 or less than pressing plate 1211 width.
The length scale of pressing piece 130 determines that it is pressed on the stability on workpiece, i.e. the length of pressing piece 130 is got over
Long, the stability being pressed on workpiece is higher, but simultaneously, the resistance that workpiece passes through pressing piece 130 will increase；On the contrary
, if the length of pressing piece 130 is shorter, the resistance that workpiece passes through pressing piece 130 will reduce, but its be pressed on it is steady on workpiece
Qualitative opposite decrease.In a preferred embodiment, the length range of pressing piece 130 is preferably 5mm-50mm.
The thickness of flexible sheets is worked as depending on the surface roughness for compressing dynamics and workpiece to be processed on workpiece
The thickness of flexible sheets is thicker, compresses that dynamics is bigger to workpiece, since the contact area of single flexible piece and workpiece surface increases
Greatly, therefore, to the more demanding of the surface flatness of workpiece that is pressed.Identical, when the thickness of flexible sheets is thinner,
Will accordingly it become smaller to the dynamics that compresses of workpiece, since the contact area of single flexible piece and workpiece surface becomes smaller, it is right
The requirement of the surface flatness of the workpiece pressed is relatively low.In a preferred embodiment, the thickness range of flexible sheets is preferably
0.5mm-4.0mm。
In addition, flexible sheets and the size of the angle a of worktable upper surface 111 also determine that it compresses dynamics to workpiece,
I.e. when the angle a of flexible sheets and worktable upper surface 111 is bigger, to workpiece to compress dynamics smaller；When flexible sheets and work
The angle a for making platform upper surface 111 gets over hour, to workpiece to compress dynamics bigger.Between flexible sheets and worktable upper surface 111
Angle a range preferably from 30 degree of -85 degree.
It please join Fig. 3, be the sectional view of pressing piece embodiment 2 at A-A in Fig. 1, it was found from sectional view, present embodiment
The flexible elastomer 231 of 2 × 12 arrays arrangement is provided on pressing piece 230, which is flexible sheets.Wherein, originally
The thickness of flexible sheets and the width of pressing piece 230 and the setting of length scale and reality in embodiment and following embodiments
The setting for applying relevant parameter in mode 1 is similar；The size setting of the angle a of flexible sheets and worktable upper surface and embodiment
The setting of relevant parameter is similar in 1, and details are not described herein.
It please join Fig. 4, be the sectional view of pressing piece embodiment 3 at A-A in Fig. 1, it was found from sectional view, present embodiment
The flexible elastomer 331 of 5 × 8 arrays arrangement is provided on pressing piece 330, which is flexible column, compared to relatively real
For applying the flexible sheets described in mode 1, this flexible column can reduce the requirement of the surface flatness of the workpiece to being pressed,
But it at the same time, also reduces flexible column and dynamics is compressed to workpiece.Wherein, the diameter range of flexible column is preferably 1mm-
10mm。
It please join Fig. 5, be the sectional view of pressing piece embodiment 4 at A-A in Fig. 1, it was found from sectional view, present embodiment
The flexible elastomer 431 of array arrangement is provided on pressing piece 430, which is flexible sheets and the group of flexible column
It closes.For flexible sheets described in the embodiment that compares 1, which can increase compresses dynamics to workpiece
While, additionally it is possible to reduce the requirement of the surface flatness of workpiece.
Embodiment described above only expresses the several embodiments of the present invention, and description is more specific and detailed, but simultaneously
Cannot the limitation to the scope of the claims of the present invention therefore be interpreted as.It should be pointed out that for those of ordinary skill in the art
For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the guarantor of the present invention
Protect scope.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
