Some embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.

Fig. 1-6 show an embodiment of the present invention, which is a full-automatic gear grinding machine for felling chain, the bottom support of which is a table-shaped support structure of the machine base 2, one side of the machine base 2 is provided with a pressing device 5, the top of the machine base 2 is provided with a protective cover 6 and a chain dragging device

The compressing device 5 in the embodiment is a U-shaped elastic compression bar with an opening at the upper part, the chain supporting plate 1 is detachably clamped in the compressing device 5, the chain 3 is installed on the chain supporting plate 1, the compressing device 5 can also directly clamp the felling complete machine, and the chain is not required to be detached to be ground.

A grinding wheel angle adjusting bracket 8 and a motor are arranged in the protective cover 6 in the embodiment; the horizontal angle of the grinding wheel angle adjusting support 8 can be adjusted, and the grinding wheel angle adjusting support is a swing arm with a locking device, the top of the grinding wheel angle adjusting support 8 extends out of the protective cover 6, the top of the grinding wheel angle adjusting support 8 is hinged with one end of a grinding wheel lifting support arm 9, a lifting support guide wheel 10 is installed at the position, close to the cam 7, of the grinding wheel lifting support arm 9, a rotation adjusting device 11 is arranged at the other end of the grinding wheel lifting support arm 9, and a grinding machine 12 is installed on the rotation adjusting device 11; the part of the motor which extends out of the protective cover 6 is provided with a cam 7.

The chain dragging device in this embodiment includes linear slide rail 13 that sets up at frame 2 top, and sliding connection has sliding block 14 in linear slide rail 13, and sliding block 14 passes through crank 16 with cam 7 and constitutes slider-crank mechanism, and 14 one side fixedly connected with axles of sliding block, epaxial rotatable claw 15 that is connected with push away, and claw 15 is equipped with two that are close to around, and the one end of the axle far away of claw 15 is equipped with the balancing weight.

The lifting support guide wheel 10 is tangent to the excircle of the cam 7, the rotation adjusting device 11 comprises a shaft sleeve capable of rotating radially and a structure for adjusting the position left and right, pins are arranged on the two parts to prevent slipping, and the adjustable arrangement in multiple directions can ensure that the grinding wheel can accurately polish the chain cutter teeth.

Wherein, for the chain support plate 1, if the length of the chain 3 to be ground is changed, the length of the chain support plate 1 can be adjusted by the telescopic locking device 19.

In order to directly clamp the felling complete machine for polishing, a felling support seat 17 is arranged on one side of the machine base 2, and the felling support seat 17 is an L-shaped rod piece and is rotatably arranged on the machine base 2 through a cylindrical pin 18. Thus, when necessary, the felling support seat 17 is rotated out to support the weight of the felling saw cylinder body.

The operation principle of the embodiment is as follows:

firstly, the chain 3 is arranged on the chain supporting plate 1, then the pressing device 5 is used for clamping the chain, the angle position of the grinder 12 is adjusted, a push claw 15 is put down, the push claw 15 naturally falls on the chain 3, and after the preparation work is finished, the motor is turned on for grinding teeth.

The motor drives the cam 7 to rotate, the cam 7 drives the sliding block 14 to reciprocate through the crank 16, when a pushing claw 15 on the sliding block 14 moves forwards, the pushing claw props against the cutter teeth on the chain 3, the chain 3 rotates forwards, at the moment, the lifting support guide wheel 10 tangent to the cam enables the grinding machine 12 to be far away from the chain 3, when the sliding block 14 moves backwards, the pushing claw 15 simultaneously moves backwards, at the moment, the lifting support guide wheel 10 tangent to the cam enables the grinding machine 12 to be close to the chain 3 for grinding the cutter teeth, and the grinding operation is repeated to finish grinding of the cutter teeth on one side of the chain 3.

Because the cutter teeth on the felling chain are designed in a left-right asymmetrical mode, after the cutter teeth on one side are polished, one push claw which finishes the work is lifted, the other push claw is put down, the actions are repeated, and the polishing of the cutter teeth on the other side is finished.

Finally, the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and other modifications or equivalent replacements made by the technical solutions of the present invention by those of ordinary skill in the art should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
