At this time, as shown in FIG. 4, the access hole 633 of the support block 63 has a spatial structure that penetrates up and down and is open forward to facilitate front insertion of the punching head 40.

Therefore, as shown in FIG. 5, when the punching head 40 is lowered and the support block 63 is pressed and moved downward, the holding block 61 also moves downward to form a seating space of the workstation 20 ( Fix the timing belt (1) accommodated in 21).

And as shown in FIG. 2, the holding unit 60 includes a holding hole 651 formed to penetrate vertically through the holding block 61, and an upper side of the holding hole 651. A pressure member 653 having a step portion 652 formed, a slider 653a that is inserted into the holding hole 651 and slides up and down, and a pressure head 653b exposed downward at the bottom of the pressure member 653, the pressure member A stopper 654 is coupled to the top of the slider 653a of 653 and is caught in the upper peripheral area of the holding hole 651, and is interposed between the step 652 and the pressing head 653b. A pressing means 65 consisting of a pressing spring 655 that elastically supports the pressing member 653 is further provided, so that when the holding block 61 is lowered, the pressing head 653b of the pressing member 653 is timing. Pressurize the belt (1).

At this time, when the manipulation of the operating handle 51 is released, the compressed pressure spring 655 is restored and the pressure member 653 returns to its original position.

As shown in FIG. 3, the holding unit 60 is inserted into each post 62 and is interposed between the holding block 61 and the base 10 to elastically support the holding block 61. By further providing a pair of elastic springs 66, when the holding block 61 is lowered, the elastic springs 66 are compressed while being vertically guided downward by each post 62, and the operating handle When the operation of (51) is released, the compressed elastic spring (66) is restored and the holding block (61) returns to its original position.

Meanwhile, the punching jig for timing belt drilling according to the present invention further includes a displacement means (70).

The displacement means 70 is

As shown in Figures 7 and 8,

To change the position of the position pin 23,

A recess 71 formed long forward and backward while being recessed downward into the bottom surface of the seating space 21 of the workstation 20,

A sliding groove 72 extending left and right at the bottom of the recess 71 and extending forward and backward,

A displacement plate (73) arranged to slide back and forth along the sliding groove (72) and having the seating space (21) on its upper surface,

A plurality of pinholes 74 are formed through the left and right areas of the upper surface of the workstation 20 and are arranged at regular intervals before and after and connected to the sliding groove 72,

A plurality of corresponding pinholes 75 are formed through the displacement plate 73 and are disposed at regular intervals before and after, corresponding to the pinholes 74, and

A fixing pin (76) passing through the pinhole (74) and inserted into the corresponding pinhole (75).

It is made including.

At this time, since the position pin 23 is provided on the displacement plate 73, the fixing pin 76 is removed, the displacement plate 73 is moved to a desired position by sliding, and then the fixing pin 76 is moved. The displacement plate 73 can be fixed by inserting it from the pinhole 74 into the corresponding pinhole 75. Ultimately, by displacing the front and rear positions of the displacement plate 73, the position of the position pin 23 provided therewith can also be displaced, allowing the spacing of perforated holes formed in the timing belt 1 to be adjusted. In other words, the punching pin 41 is lowered to widen or reduce the gap between the position of the hole to be punched and the position pin 23 into which the hole has already been punched, thereby increasing the number of holes to be punched in the timing belt 1. The spacing can be adjusted.
