Abstract
The invention discloses a handhold hammer drill machine tool. The handhold hammer drill machine tool comprises a machine body, a machine case, a driver, a hammering system and a cutter clamping system, and is characterized in that a double-layer bevel gear structure and an eccentric unit fixed on a middle shaft are also arranged in the machine case; the driver is connected with a large gear of the cutter clamping system by one layer of the bevel gear of a double-layer bevel gear structure; upper layer of the bevel gear is connected with a gear of the driver; the front section of an impactor of the hammering system is an impact hammer; a hollow cavity is formed at the back section of the impactor; and the eccentric unit is positioned into the hollow cavity of the impactor. The handhold hammer drill machine tool is driven by using the double-layer bevel gear structure instead of the conventional multiple groups of gears; and meanwhile, and a cylinder piston is driven by using the eccentric unit on the middle shaft instead of the traditional swinging rod or an eccentric connecting rod, so that the handhold hammer drill machine tool has a simple and compact structure and is light and ingenious and flexible to work, and a person feels comfortable during holding the handhold hammer drill machine tool.
Description
Technical field
The present invention relates to the Handhold hammer drill machine tool of a kind of hammering fragmentation or rotary cutting working medium.
Background technology
At present, known Handhold hammer drill machine tool is drive cylinder or eccentric ratio to drive the piston compression gas medium in cylinder to promote to impact son by fork to move back and forth, realize hammering on the one hand, thus broken working medium; Drive holding cutter system to rotate by gear or axle to realize cutting working medium on the one hand; But this Handhold hammer drill machine tool is very complicated and heavy, uncomfortable and dumb when gripping work.
Summary of the invention
In order to overcome current Handhold hammer drill machine tool complex structure and the shortcoming of heaviness, the object of the present invention is to provide the hand held power machine that a kind of structure is simple and light and handy.
The technical solution used in the present invention is: a kind of Handhold hammer drill machine tool, include body, casing, driver, hammer systems, knife clamping system, it is characterized in that: in casing, be also provided with a bilayer be fixed on jackshaft bore toothing and eccentric unit, described driver is connected with the gear wheel of knife clamping system by lower floor's cone tooth of double-deck cone toothing, and upper strata cone tooth is connected with the gear of driver; The sub-leading portion of impact of described hammer systems is jump bit, and back segment has a cavity; Described eccentric unit is positioned at the cavity impacting son.
Described eccentric unit is a cam structure, is fixed on jackshaft by pin.
The inwall front end of the sub-cavity of described impact is provided with convex surface, and rear inner wall is provided with concave curved surface.
The bilayer cone toothing that transmission of the present invention adopts one to have a two-layer bevel gear, bore tooth by the output gear of driver with double-deck upper strata of bore toothing and coordinates, driving bilayer bores toothing rotation.Torsion is passed to the jackshaft of close-fitting with it by double-deck cone toothing on the one hand, jackshaft is rotated, thus drive eccentric finite element rotation, curved surface and two curved surfaces impacting son of eccentric unit clash into or extrude can realize impacting and subly accelerate forward and reset, impact son to accelerate can clash into tool shank forward, thus make the broken working medium of cutter; Lower floor's cone tooth of double-deck cone toothing coordinates with the gear wheel be arranged in holding cutter system on the one hand, thus drives gear wheel to rotate, and carry its tools system rotates, and makes cutter rotary cutting working medium.
The present invention replaces former multiple sets of teeth to take turns transmission by adopting a bilayer cone toothing with two-layer bevel gear, double-deck cone toothing realizes the cutting function of cutter on the one hand by the transmission of cone tooth, impact son by the eccentric unit drives on jackshaft on the other hand and realize hammering function, fork before replacing or eccentric ratio drive cylinder piston to promote to impact son, thus it is simple and compact for structure, portable and smart, during gripping work, people feels comfortable and works flexibly.

Detailed description of the invention
Below in conjunction with accompanying drawing and case study on implementation, the present invention is further described.
From Fig. 1,2, Handhold hammer drill machine tool of the present invention, includes body 1, casing 15, driver 2, hammer systems, knife clamping system, is also provided with a bilayer be fixed on jackshaft 11 and bores toothing 10 and eccentric unit 4 in casing 15; Lower floor's cone tooth 14 of double-deck cone toothing is connected with the gear wheel 7 of knife clamping system, and upper strata cone tooth 13 is connected with the gear 3 of driver; Hammer systems comprises impact, impacting sub-leading portion is jump bit, and back segment has a cavity, and eccentric unit is positioned at and impacts sub-cavity, make eccentric unit shock or pinch shock realize impacting seesawing of son by the rotation of eccentric unit, thus realize hammering function.Knife clamping system comprises holding cutter structure 8, gear wheel 7 and cutter 9.
From Fig. 3,4, impact son 6 and be bearing in holding cutter unit 8, impacting sub-leading portion is jump bit, and back segment has a cavity, and the inwall front end of its cavity is provided with convex surface, and rear inner wall is provided with concave curved surface.Eccentric unit 4 is a cam structure, is arranged in the sub-cavity of impact of hammer systems.
More than show and describe general principle of the present invention and principal character and advantage of the present invention; the technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications; these changes and improvements all fall in the claimed scope of the invention, and application claims protection domain is defined by appending claims and equivalent thereof.
