Swinging cutter-relieving mechanism for slot machine

Abstract

The invention provides a swinging cutter-relieving mechanism for a slot machine. A cutter bar shaft base and a cam case are integrally connected in a flexible connection manner, a cutter located outside the cutter bar shaft base and used for machining a slot is fixed to the end of the other end of a cutter bar shaft, a swinging-range adjusting device which is in contact with the bottom face of thecam case is fixed to one end of the cutter bar shaft base, a following limiting device is in contact with the outer step circumferential wall of the end of a space cam, and periodic swinging cutter-relieving movement of the cutter bar shaft located in the cutter bar shaft base and reciprocating rectilinear movement of the cutter bar shaft are achieved under the effect of arc protrusions and a camfollower fitting a process returning groove. According to the swinging cutter-relieving mechanism for the slot machine, the periodic swinging cutter-relieving movement of the cutter bar shaft locatedin the cutter bar shaft base and the reciprocating rectilinear movement of the cutter bar shaft can be achieved, the swinging range of the cutter bar base can be adjusted, the machining range of slotparts is widened, the machining efficiency of the slot parts is greatly improved after the space cam is in linkage connection with main movement, working environments in the slot-machine high-frequency working environment are met, and working is stable and reliable.

Description

technical field [0001] The invention belongs to the technical field of slot processing equipment, and in particular relates to an oscillating knife-releasing mechanism used in a slot machine. Background technique [0002] At present, when processing grooved parts, most of the oscillating knife-relieving mechanisms used in processing equipment adopt electromagnetic structures. Since the equipment for processing grooved parts (such as gear shaping machines, gantry milling and gantry planers) reciprocates The processing frequency of the movement is not high. Therefore, the use of the electromagnetic oscillating tool letting structure can meet the tool letting requirements when machining grooved parts. With the continuous improvement of machining efficiency, the oscillating tool letting mechanism is linked with the main movement. , so as to increase the frequency of the knife, in the processing environment with a high frequency of the knife, the swing of the electromagnetic stru...

[0002] At present, when processing grooved parts, most of the oscillating knife-relieving mechanisms used in processing equipment adopt electromagnetic structures. Since the equipment for processing grooved parts (such as gear shaping machines, gantry milling and gantry planers) reciprocates The processing frequency of the movement is not high. Therefore, the use of the electromagnetic oscillating tool letting structure can meet the tool letting requirements when machining grooved parts. With the continuous improvement of machining efficiency, the oscillating tool letting mechanism is linked with the main movement. , so as to increase the frequency of the knife, in the processing environment with a high frequency of the knife, the swing of the electromagnetic structure makes the reaction speed of the knife structure slow, which cannot meet the use requirements in the high-frequency processing environment, and the work reliability is poor. problem, need to improve
