Description

The cutting distance control device

Technical field

The utility model belongs to the production equipment technical field, is specifically related to a kind of cutting distance control device.

Background technology

Existing mainly is to take manual type to carry out cutting operation three times when the cutting products end face, promptly arrest an end of product and be placed on the reference block and its other end is cut with machine with hand, well cutting after once manual again readjustment some distance once more its end is cut, cut readjustment manual again after twice a bit apart from once more its end being cut, this as can be seen to finish three cuttings mainly be to be undertaken by the manual mode that adds range estimation, and the shortcoming of obviously taking this mode is that operation is wasted time and energy, inefficiency, and the precision that is difficult to guarantee to cut stroke.

Summary of the invention

Technical problem to be solved in the utility model is the present situation at prior art, and a kind of cutting distance control device of simple to operate, high efficiency is provided.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: in the cutting distance control device, comprise supporting plate and be fixed on slide rail on the supporting plate, the measure of being taked is: be fitted with the slide block of slide rail slip relatively on the slide rail, on supporting plate, also be fitted with cam, this cam has a plurality of distance of center circle that arrive from different arc surfaces, between slide block and slide rail, be fitted with back-moving spring, be resisted against an end of product at an end of the effect sliding block of back-moving spring, the other end of slide block is resisted against on the arc surface of cam.

The measure of taking for the optimization such scheme specifically comprises:

In above-mentioned cutting distance control device, the arc surface of cam is divided into first arc surface, second arc surface and three-arc face, first arc surface to the distance in the cam center of circle greater than the distance of second arc surface to the cam center of circle, second arc surface to the distance in the cam center of circle greater than the distance of three-arc face to the cam center of circle.

In above-mentioned cutting distance control device, be fitted with on the cam and can drive the handle that cam rotates to corresponding arc surface, between cam and handle, be fitted with pad.

In above-mentioned cutting distance control device, the both ends of slide block are fitted with front apron and backboard respectively, and front apron and backboard are separately fixed at the both ends of slide block, and an end of front apron and product leans, and backboard and cam lean.

Compared with prior art, advantage of the present utility model is to have by rotation a plurality of to the cam of distance of center circle from different arc surfaces, arc surfaces different on the cam is resisted against on the slide block, thereby make stroke obtain changing the cutting of finishing the product end, adopt this mode to position to regulate have simple to operate, cost is low, versatility good berth efficient advantages of higher.

Fig. 2 is the internal structure schematic diagram of Fig. 1.

Among the figure, supporting plate 1; Slide rail 2; Slideway 21; Slide block 3; Cam 4; First arc surface 41; Second arc surface 42; Three-arc face 43; Back-moving spring 5; Front apron 6; Backboard 7; Handle 8; Pad 9; Product 10.

The specific embodiment

Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.

As depicted in figs. 1 and 2, this cutting distance control device, comprise supporting plate 1 and be fixed on slide rail 2 on the supporting plate 1, be fitted with the slide block 3 of slide rail 2 slips relatively on the slide rail 2, on supporting plate 1, also be fitted with cam 4, have two small sircle hole and big holes that are used to install cam 4 that are used to install slide rail 2 usefulness on the supporting plate 1, be fitted with on the cam 4 and can drive the handle 8 that cam 4 rotates to corresponding arc surface, between cam 4 and handle 8, be fitted with pad 9.

The slip of slide block 3 on slide rail 2 for convenience, slide rail 2 integral body are the T font, are shaped on slideway 21 on slide rail 2, are shaped on the sliding chamber of the T font that is interlocked with slideway 21 on the slide block 3, and sliding chamber just in time is fastened on the slideway 21 during work.

Maximum innovative point of the present utility model is the shape of cam 4, this cam 4 has a plurality of distance of center circle that arrive from different arc surfaces, the arc surface of cam 4 is divided into first arc surface 41, second arc surface 42 and the three-arc face 43, first arc surface 41 arrives the distance in cam 4 centers of circle greater than the distance of second arc surface 42 to cam 4 centers of circle, and second arc surface 42 arrives the distance in cam 4 centers of circle greater than three-arc face 43 to the distance in cam 4 centers of circle.

For the both ends that make slide block 3 respectively with end of product 10 and cam 4 be close to against, between slide block 3 and slide rail 2, be fitted with back-moving spring 5, be resisted against an end of product 10 at an end of the effect sliding block 3 of back-moving spring 5, the other end of slide block 3 is resisted against on the arc surface of cam 4.Simultaneously again for convenience slide block 3 install and guarantee against stability, the both ends of slide block 3 are fitted with front apron 6 and backboard 7 respectively, front apron 6 and backboard 7 are separately fixed at the both ends of slide block 3, and front apron 6 leans with an end of product 10, and backboard 7 leans with cam 4.

Operation principle of the present utility model is as follows:

In the time need cutting to the end of product 10, rotating cam 4 is resisted against first arc surface 41 of cam 4 and makes product 10 location on the backboard 7, an end of product 10 under the effect of back-moving spring 5 be against and be close on the front apron 6, after the cutting of finishing product 10 other ends first time; Drive cam 4 rotations and second arc surface 42 of cam 4 is resisted against on the backboard 7 with hand operated handle 8, here because first arc surface 41 arrives the distance in cam 4 centers of circle greater than second arc surface 42 to the distance in cam 4 centers of circle, effect sliding block 3 at back-moving spring 5 just moves a certain distance relatively backward like this, that is to say slide block 3 to regulate the distance that moves backward be first arc surface 41 the poor of distance to the distance in cam 4 centers of circle and second arc surface 42 to cam 4 centers of circle, the product 10 1 ends displacement distance that also is first arc surface 41 to the distance in cam 4 centers of circle and second arc surface 42 to cam 4 centers of circle poor backward just relatively like this is after the cutting of finishing product 10 other ends second time; Drive cam 4 rotations and the three-arc face 43 of cam 4 is resisted against on the backboard 7 with hand operated handle 8, here because second arc surface 42 arrives the distance in cam 4 centers of circle greater than three-arc face 43 to the distance in cam 4 centers of circle, effect sliding block 3 at back-moving spring 5 just moves a certain distance relatively backward like this, that is to say slide block 3 to regulate the distance that moves backward be second arc surface 42 the poor of distance to the distance in cam 4 centers of circle and three-arc face 43 to cam 4 centers of circle, the product 10 1 ends displacement distance that also is second arc surface 42 to the distance in cam 4 centers of circle and three-arc face 43 to cam 4 centers of circle poor backward just relatively like this, thus the cutting for the third time of product 10 other ends finished.

Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from the defined scope of spirit of the present utility model.
