The punching machine needs to clamp the mold with a clamp before opening the holes in the mold. The square mold can be clamped directly by the clamp on the punching machine, but if the cylindrical mold needs to be processed, the clamp on the punching machine needs to be replaced. The clamp on the punching machine is usually fixed together with multiple sets of bolts, which is very troublesome to disassemble and assemble. Utility Model Content

By setting the positioning mechanism 4, molds of different shapes can be quickly positioned.

[0023] The positioning mechanism 4 includes a bidirectional screw 41, a rotating shaft 42, a worm 43, a handle 44, a clamp 45, a crank arm 46, a positioning roller 47, a worm gear 48, a knob 49, and a rubber pad 410; one end of the bidirectional screw 41 is rotatably connected to the inner wall of the storage platform 3, and the other end of the bidirectional screw 41 passes through the storage platform 3 and is fixedly installed with a handle 44, and the bidirectional screw 41 is rotatably connected to the penetration of the storage platform 3, and the bidirectional screw 41 is rotated by rotating the handle 44, and the rotation of the bidirectional screw 41 can drive the two screws connected to the bidirectional screw 41 through the thread. The clamping blocks 45 slide synchronously in opposite directions on the inner wall of the storage table 3. The inner wall of the storage table 3 is slidably connected with two sets of clamping blocks 45. The inner walls of the two sets of clamping blocks 45 are threadedly connected to the outer wall of the bidirectional screw 41. The two sets of clamping blocks 45 are close to each other until the rubber pads 410 on the side walls of the clamping blocks 45 are tightly attached to the outer wall of the mold. The positioning of the mold can be completed. One end of the rotating shaft 42 is rotatably connected to the inner wall of the clamping block 45, and the other end of the rotating shaft 42 passes through the clamping block 45 and is fixedly installed with a crank arm 46, and the rotation shaft 42 and the clamping block 45 are interlocked. The outer wall of the rotating shaft 42 is fixedly mounted with a worm gear 48, and the end of the crank arm 46 away from the rotating shaft 42 is fixedly mounted with a positioning roller 47. The cylindrical mold can be positioned by using two sets of clamping blocks 45 in cooperation with the positioning rollers 47 on both sides thereof. The molds of different shapes can be quickly positioned without disassembling the clamps. The outer walls of the positioning rollers 47 and the clamping blocks 45 are fixedly mounted with rubber pads 410. The two sets of rotating shafts 42 drive the two sets of crank arms 46 to rotate in opposite directions until the two sets of crank arms 46 drive the two sets of positioning rollers 47 It fits against the outer wall of the cylindrical mold so that the rubber pad 410 on the outer wall of the positioning roller 47 fits tightly against the outer wall of the cylindrical mold. One end of the worm 43 is rotatably connected to the inner wall of the clamping block 45. The other end of the worm 43 passes through the clamping block 45 and is fixedly installed with a knob 49. The worm 43 is rotatably connected to the penetration point of the clamping block 45. The worm 43 is meshed with a worm wheel 48. The worm 43 is rotated by the knob 49. The rotation of the worm 43 and the two sets of worm wheels 48 meshing with it can drive the two sets of rotating shafts 42 to rotate synchronously in opposite directions.

[0024] The inner wall of the above-mentioned positioning roller 47 is provided with an auxiliary mechanism 5, and the positioning effect of the positioning roller 47 on the cylindrical mold can be further improved by providing the auxiliary mechanism 5. The auxiliary mechanism 5 includes a slide bar 51, a positioning plate 52, an anti-skid pad 53, and a bolt 54; the slide bar 51 is slidably connected to the inner wall of the positioning roller 47, and a positioning plate 52 is fixedly installed on the top of the slide bar 51. The top of the cylindrical mold can be positioned by using the positioning plate 52, and multiple groups of anti-skid pads 53 are fixedly installed on the lower surface of the positioning plate 52. The positioning plate 52 is driven downward by the slide bar 51 to make an interference fit between the anti-skid pad 53 at the bottom of the positioning plate 52 and the cylindrical mold. The inner wall of the positioning roller 47 is rotatably connected with a bolt 54, and the bolt 54 penetrates the positioning roller 47. The outer wall of the bolt 54 is threadedly connected to the inner wall of the slide bar 51. After the two groups of positioning rollers 47 position the cylindrical mold, the bolt 54 is rotated again to drive the slide bar 51 threadedly connected thereto to slide downward on the inner wall of the positioning roller 47.

[0025] Working principle: Place the mold on the storage table 3, and then rotate the bidirectional screw 41 through the handle 44. The rotation of the bidirectional screw 41 can drive the two groups of clamping blocks 45 threadedly connected to it to slide synchronously in opposite directions on the inner wall of the storage table 3, and make the two groups of clamping blocks 45 approach each other until the rubber pads 410 on the side walls of the clamping blocks 45 are tightly attached to the outer wall of the mold, and the positioning of the mold can be completed. When it is necessary to position the cylindrical mold, first use the two groups of clamping blocks 45 to cooperate with the rubber pads 410 on the side walls to clamp the cylindrical mold. After the two groups of clamping blocks 45 clamp the cylindrical mold, turn the knob 49 rotates the worm 43, and the two groups of worm wheels 48 meshing with it can drive the two groups of rotating shafts 42 to rotate synchronously in opposite directions, so that the two groups of rotating shafts 42 drive the two groups of curved arms 46 to rotate in opposite directions, until the two groups of curved arms 46 drive the two groups of positioning rollers 47 to fit the outer wall of the cylindrical mold, so that the rubber pads 410 on the outer walls of the positioning rollers 47 are tightly fitted to the outer wall of the cylindrical mold. At this time, the cylindrical mold can be positioned by using two groups of clamps 45 to cooperate with the positioning rollers 47 on both sides thereof. There is no need to disassemble the clamp, and molds of different shapes can be quickly positioned, which is more convenient to use.

[0026] After the two sets of positioning rollers 47 have positioned the cylindrical mold, the bolt 54 is rotated to drive the sliding rod 51 threadedly connected thereto to slide downward on the inner wall of the positioning roller 47 until the sliding rod 51 drives the positioning plate 52 to fit against the top of the cylindrical mold, so that the anti-slip pad 53 at the bottom of the positioning plate 52 has an interference fit with the cylindrical mold. The positioning plate 52 can be used to position the top of the cylindrical mold, thereby further improving the positioning effect of the positioning roller 47 on the cylindrical mold.

[0027] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
