Abstract
The invention discloses a clamping device capable of reducing the idler stroke of a cutter. The clamping device capable of reducing the idler stroke of the cutter aims to solve the problem that an existing clamping device can clamp only one workpiece every time, so that the waiting idler stroke of the cutter is increased. The clamping device capable of reducing the idler stroke of the cutter comprises a clamping platform. A clamping groove is formed in the upper portion of the clamping platform. The two side groove walls of the clamping groove are in a swallow tail shape. A through hole is formed between the two groove walls of the clamping groove. A guide rod penetrates through the through hole. The lower end of the guide rod is fixed. The upper end of the guide rod is sleeved with a pressing protruding block which is in a reverse-cone shape in a non-contact mode. The pressing protruding block is connected with a force application rod. A limiting block capable of limiting the downward position of the pressing protruding block is arranged on the guide rod. The clamping device is capable of reducing the idler stroke of the cutter when the cutter waits for machining.
Description
Technical field
The present invention relates to Machining Technology, be specifically related to a kind of clamping device that reduces cutter idle stroke.
Background technology
workpiece is manufactured in process, all needs to adopt fixture to carry out clamping position to workpiece, and in small lot batch manufacture processing, General Requirements clamp structure is simple, cost-saving.But at present, existing fixture generally once can only clamp a workpiece, adopt like this cutter to add one by one man-hour to workpiece, process after a workpiece, need this workpiece to discharge, insert again another workpiece and clamp after could adopt again tool sharpening, this has just increased the idle stroke that cutter etc. is bide one's time, and also affects the working (machining) efficiency of workpiece simultaneously.
Summary of the invention
The invention provides a kind of clamping device that reduces cutter idle stroke, to solve existing fixture, once can only clamp a workpiece, increase the problem that cutter is waited for idle stroke.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
Can reduce the clamping device of cutter idle stroke, comprise grain-clamping table, grain-clamping table top has holding tank, described holding tank both sides cell wall is dovetail shaped, between described holding tank two cell walls, has through hole, is equipped with guide rod in through hole, the lower end of guide rod is fixed, the upper end of guide rod is set with the compression projection of inverted cone shape, compresses projection and is connected with a force application rod, is provided with and can limits the limited block that compresses projection downstream position on guide rod.
The operation principle of this fixture: two holding tanks of cutting apart that are positioned at guide rod both sides can at least be inserted a workpiece, insert after workpiece, force application rod promotes to compress projection and moves downward along guide rod, until prop up workpiece outer rim, and clamping work pieces, now limited block, also by propping up the bottom that compresses projection, makes to compress projection and no longer continues to move downward, and plays spacing effect.This clamping device once at least can clamp two workpiece simultaneously, and cutter at least can be processed two workpiece at every turn, so just can reduce the idle stroke of cutter, increases work efficiency simultaneously.
Further, described guide rod be circumferentially positioned at compress projection below be provided with back-moving spring.While unclamping workpiece, after the power of force application rod disappears, under the effect of back-moving spring, compress the projection reset that can automatically move upward, so that unclamp workpiece.
Accompanying drawing explanation
Fig. 1 is the structural representation that the present invention can reduce the clamping device embodiment of cutter idle stroke.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
The clamping device of reduced cutter idle stroke as shown in Figure 1, comprise grain-clamping table 1, grain-clamping table 1 top has holding tank 2, holding tank 2 both sides cell walls are dovetail shaped, between 2 liang of cell walls of holding tank, have through hole, in through hole, be equipped with guide rod 3, the lower end of guide rod 3 is fixed, the upper end of guide rod 3 is set with the compression projection 4 of inverted cone shape, compress between projection 4 and guide rod 3 and be provided with a circle cushion cover, compressing projection 4 is connected with a force application rod 5, force application rod is connected with the piston rod of a cylinder, on guide rod 3, be provided with and can limit the limited block 5 that compresses projection 4 downstream position, guide rod 3 be circumferentially positioned at compress projection 4 below be provided with back-moving spring 6.The object of design cushion cover is increase to compress the friction between projection and guide rod, and excessive velocities when avoiding compressing projection and moving downward is excessive to the impact of limited block and workpiece.
Claims (2)
1. can reduce the clamping device of cutter idle stroke, it is characterized in that, comprise grain-clamping table, grain-clamping table top has holding tank, and described holding tank both sides cell wall is dovetail shaped, between described holding tank two cell walls, have through hole, in through hole, be equipped with guide rod, the lower end of guide rod is fixed, and the upper end of guide rod is set with the compression projection of inverted cone shape, compress projection and be connected with a force application rod, on guide rod, be provided with and can limit the limited block that compresses projection downstream position.
2. the clamping device that reduces cutter idle stroke according to claim 1, is characterized in that, described guide rod be circumferentially positioned at compress projection below be provided with back-moving spring.
