Description

Technical Field

[0001] This utility model belongs to the field of punching machines and relates to a tool pitch adjustment mechanism for a metal chain tooth double-blade punching machine. Background Technology

[0002] A tooth punching machine is used to punch away portions of the chain teeth at equal intervals as needed, creating space for the installation of top and bottom stop switches and the pull head. The punching distance is determined by the requirements. However, changing the cutters on a tooth punching machine is relatively troublesome, and sometimes slight deviations are difficult to correct by simply changing the cutters. Summary of the Invention

[0003] In view of the above problems, the present invention provides a tool spacing adjustment mechanism for a metal chain tooth double-blade punching machine. This device has the advantage of being able to easily adjust the tool spacing, thereby adjusting the length of the punching teeth.

[0004] The objective of this invention is achieved as follows:

[0005] A tool spacing adjustment mechanism for a metal chain tooth double-blade punch includes a tool holder, a main blade fixed below the tool holder with the blade head facing downwards, an adjusting blade on the side of the main blade with the blade head also facing downwards and horizontally positioned with the blade head of the main blade, a slot formed in the middle of the adjusting blade, an adjusting fixing block provided in the slot, the adjusting fixing block being fixedly connected to the main blade, a screw hole formed at one end of the adjusting blade with an adjusting set screw provided in the screw hole, one end of the adjusting set screw being screwed into the screw hole, and a smooth rod provided at the other end of the adjusting set screw with limiting ends at both ends, the smooth rod extending into the slot and rotatably connected to the adjusting fixing block, a through groove formed on the adjusting fixing block matching the smooth rod, and the limiting ends at both ends of the smooth rod abutting against both sides of the adjusting fixing block.

[0006] With the above settings, when the length of the punch needs to be adjusted, simply rotate the adjusting screw. Since the smooth part of the adjusting screw is rotatably connected to the adjusting fixing block and has two limit ends that restrict lateral movement, the adjusting screw rotates freely relative to the adjusting fixing block. The other end of the adjusting screw is screwed to the screw hole. Rotating the adjusting screw can drive the adjusting blade to move, thereby adjusting the distance between the adjusting blade and the main blade, thus changing the overall length of the main blade and the adjusting blade, and ultimately changing the length of the punch.

[0007] The present invention is further configured such that: the adjusting blade includes an adjusting blade body and an adjusting blade head, and the slot is provided in the middle of the adjusting blade body.

[0008] The present invention is further configured such that: a slot is provided in the middle of the main blade, and the end of the adjusting blade connected to the main blade is locked in the slot.

[0009] The present invention is further configured such that: the main blade is also formed with an adjustment hole, and the adjustment blade is provided with an adjustment groove corresponding to the adjustment hole. The adjustment groove is elongated, and a bolt is provided to pass through the adjustment groove and the adjustment hole and to be fastened with a nut.

[0010] With the above settings, the bolts can be tightened during operation to secure the main blade and adjusting blade more firmly, preventing loosening. When the blade spacing needs adjustment, simply loosen the nut for normal adjustment.

[0011] The present invention is further configured such that: a guide protrusion is formed on the side of the main blade facing the adjusting blade, and a guide groove is formed on the side of the adjusting blade facing the main blade, and the guide protrusion is slidably disposed in the guide groove.

[0012] The above settings ensure more stable blade movement when adjusting the blade spacing, keeping both blades level at all times.

[0013] The present invention is further configured such that: the screw hole is a through hole, and the end of the adjusting screw away from the guide rod is formed with an internal hexagonal groove.

[0014] With the above settings, when adjustments are needed, an Allen wrench can be inserted from the end of the screw hole away from the polished rod. The Allen wrench can be rotated to rotate the adjusting set screw. This adjustment method is both convenient and cost-effective.

[0015] The outstanding and beneficial technical effect of this invention compared with the prior art is that when it is necessary to adjust the length of the punch, it is only necessary to rotate the adjusting screw. Since the smooth part of the adjusting screw is rotatably connected to the adjusting fixing block and has two limiting ends to restrict lateral movement, the adjusting screw rotates freely relative to the adjusting fixing block. The other end of the adjusting screw is screwed to the screw hole. The rotation of the adjusting screw can drive the adjusting blade to move, thereby adjusting the distance between the adjusting blade and the main blade, thereby changing the overall length of the main blade and the adjusting blade, and finally changing the length of the punch.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0024] A tool spacing adjustment mechanism for a metal chain tooth double-blade punch includes a tool holder 1. A main blade 2 is fixed below the tool holder 1, with the blade head of the main blade 2 facing downwards. An adjusting blade 3 is provided on the side of the main blade 2, with the blade head of the adjusting blade 3 also facing downwards and horizontally arranged with the blade head of the main blade 2. A slot 4 is formed in the middle of the adjusting blade 3, and an adjusting fixing block 5 is provided in the slot 4. The adjusting fixing block 5 is fixedly connected to the main blade 2. A screw hole 6 is formed at one end of the adjusting blade 3, and an adjusting set screw 7 is provided in the screw hole 6. One end of the adjusting set screw 7 is screwed into the screw hole 6, and the other end of the adjusting set screw 7 is provided with a smooth rod 8. The two ends of the smooth rod 8 are provided with limiting ends 9. The smooth rod 8 extends into the slot and is rotatably connected to the adjusting fixing block 5. A through groove 10 matching the smooth rod 8 is formed on the adjusting fixing block 5, and the two ends of the smooth rod 9 abut against the two sides of the adjusting fixing block 5.

[0025] With the above settings, when the length of the punch needs to be adjusted, simply rotate the adjusting screw 7. Since the smooth rod part 8 of the adjusting screw is rotatably connected to the adjusting fixing block 5 and has two limiting ends 9 that restrict lateral movement, the adjusting screw 7 rotates freely relative to the adjusting fixing block 5. The other end of the adjusting screw 7 is screwed to the screw hole 6. Rotating the adjusting screw 7 can drive the adjusting blade 3 to move, thereby adjusting the distance between the adjusting blade 3 and the main blade 2, thus changing the overall length of the main blade 2 and the adjusting blade 3, and ultimately changing the length of the punch.

[0026] The adjusting blade 3 includes an adjusting blade body 11 and an adjusting blade head 12, and the slot 4 is provided in the middle of the adjusting blade body 11.

[0027] The main blade 2 has a slot 13 in the middle, and the end of the adjusting blade 3 connected to the main blade 2 is locked in the slot 13.

[0028] The main blade 2 is also formed with an adjustment hole 14. The adjustment blade 3 has an adjustment groove 15 corresponding to the adjustment hole 14. The adjustment groove 15 is elongated, and a bolt (not shown) passes through the adjustment groove 15 and the adjustment hole 14, and is secured with a nut. This design allows the main blade 2 and the adjustment blade 3 to be more firmly fixed during operation, preventing loosening. When the blade spacing needs adjustment, simply loosen the nut for normal adjustment.

[0029] The main blade 2 has a guide protrusion 16 formed on the side facing the adjusting blade 3, and the adjusting blade 3 has a guide groove 17 formed on the side facing the main blade 2. The guide protrusion 16 is slidably disposed within the guide groove 17. This design ensures more stable movement of the adjusting blade when adjusting the blade spacing, maintaining the two blade heads at a horizontal position.

[0030] The screw hole 6 is a through hole, and the end of the adjusting screw 7 away from the polished rod 8 is formed with an internal hexagonal groove 19. With the above settings, when adjustment is needed, a hexagonal wrench can be inserted from the end of the screw hole away from the polished rod, and the adjusting screw can be rotated by rotating the internal hexagonal wrench. This adjustment method is both convenient and cost-effective.

[0031] The present invention has the feature of being able to easily adjust the tool spacing, thereby adjusting the length of the punch.

[0032] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
