When material blocking shaft 6 is installed, by holding with a firm grip, material blocking shaft 6 two ends also apply certain axial force vertically inwards, put in nut 3 Compress Spring 4 that movable axis 1 axle head in the blind hole 10 of stationary axle 5 is threaded, material blocking shaft 6 two ends are shunk, material blocking shaft 6 two axial ends is aimed at the mounting hole 7 processed in advance on material backplate 8, the axial force that release applies, material blocking shaft 6 two ends are inserted mounting hole 7 and are compressed attachment face under the effect of spring 4 compressive force, play the location to material 9 or position-limiting action.During dismounting, material blocking shaft of holding with a firm grip 6 two ends also apply certain axial force vertically inwards, and material blocking shaft 6 two ends are shunk, and when material blocking shaft 6 two axial ends departs from mounting hole 7 completely, remove material blocking shaft 6, remove the location or spacing to material 9.
In the present embodiment, the internal diameter of gland 2 is less than the end face external diameter of nut 3, object prevents movable axis 1 axle head from deviating from from stationary axle 5 blind hole 10, being provided with nut 3 bottom one axle head of movable axis 1, and overlap and have gland 2 on movable axis 1, with stationary axle 5 connecting part, is for the ease of dismantling.The present invention, due to the effect of spring 4 compressive force, ensure that stability when material blocking shaft 6 is fixed.
The present embodiment achieves the axial stretching of material blocking shaft 6, is convenient to quick mounting and the dismounting of material blocking shaft 6, to realize or to remove the location of material 9 and spacing.
Embodiment 2:
On the basis of embodiment 1, present embodiments provide a kind of material blocking shaft being convenient to installation and removal, material blocking shaft 6 is made up of stationary axle 5, spring 4, nut 3, gland 2 and movable axis 1.One end of stationary axle 5 has threaded cylinder blind hole, the built-in spring 4 of cylinder blind hole, and one end cover of movable axis 1 has the gland 2 of Spielpassung, and axle head is connected with nut 3 by screw thread.Movable axis 1 axle head being connected with nut 3 is put in cylinder blind hole and contacts with spring 4, nut 3 end face holddown spring 4, and screw and tighten gland 2 in stationary axle 5 axle head, complete the assembling of material blocking shaft 6 thus.
Material blocking shaft 6 using process that the present embodiment provides:
By material blocking shaft 6 two ends of holding with a firm grip, certain axial force is applied in the homogeneous phase of two ends, now put in nut 3 Compress Spring 4 that movable axis 1 axle head in the blind hole 10 of stationary axle 5 is threaded, the Free Compression of material blocking shaft 6 can be realized within the specific limits, unclamp after aiming at mounting hole 7, just material blocking shaft 6 axle head is inserted in the mounting hole 7 that material backplate 8 is processed in advance, the location of material 9 and spacing can be realized fast.When need remove material 9 location and spacing time, material blocking shaft of holding with a firm grip equally 6 two ends, apply certain axial force in the homogeneous phase of two ends, now put in nut 3 Compress Spring 4 that movable axis 1 axle head in the blind hole 10 of stationary axle 5 is threaded, material blocking shaft 6 is compressed, and can easily material blocking shaft 6 be extracted.
