Description

Technical Field

[0001] This utility model relates to the field of roller chain processing technology, and in particular to a length-determinable cutting and positioning fixture for cutting roller chain pins. Background Technology

[0002] A roller chain is a type of chain drive used for transmitting mechanical power. It is widely used in household, industrial, and agricultural machinery, including conveyors, plotters, printing presses, automobiles, motorcycles, and bicycles. It consists of a series of short cylindrical rollers linked together and driven by a gear called a sprocket. It is a simple, reliable, and efficient power transmission device.

[0003] When processing roller chain pins, the raw materials are usually cut into certain lengths one by one. The positioning and cutting of one raw material at a time will affect the normal pushing process in order to ensure stable positioning of the raw materials, resulting in low overall processing efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a length-determinable cutting and positioning fixture for cutting roller chain pins, thereby solving the problems mentioned in the background section.

The movable seat is arranged to extend upward through the length-fixing plate at both ends. The cylinder is installed in the middle of the movable seat, and its output end is fixedly connected to the bottom of the length-fixing plate.

[0007] By adopting the above technical solution, the device can simultaneously cut two raw materials for making pins using a single cutting machine, and automatically achieve cutting and length setting, effectively improving cutting efficiency.

The bottom of the fixed seat has a slot corresponding to the inverted trapezoidal opening of the worktable. The second pressure-applying part slides up and down along the slot and is rotatably connected to the fixed seat through the adjusting bolt.

[0011] By adopting the above technical solution, it is possible to position and cut the raw materials that have been cut into pins.

[0027] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0028] Reference Figure 1-5 A length-determinable cutting and positioning fixture for cutting roller chain pins includes a worktable 1 and a positioning and pushing mechanism and an auxiliary length-determining mechanism mounted on the worktable 1. The worktable 1 has two inverted trapezoidal openings in the middle, and multiple rollers 101 are rotatably mounted on the side walls of the openings. The positioning and pushing mechanism includes a motor 2, a lead screw 3, a pushing part 4, a pressure applying part 5, a limiting part 6, and a slide rail 7. The lead screw 3 is mounted at the output end of the motor 2. The pushing part 4 is connected to the lead screw 3 and slides along the slide rail 7 mounted on the worktable 1. The limiting part 6 is fixed at the end of the worktable 1 away from the motor 2. The pressure applying part 5 is slidably mounted on the slide rail 7.

[0029] The auxiliary length-fixing mechanism includes an adjusting rod 8, a locking bolt 9, a length-fixing plate 10, a cylinder 11, and a movable seat 12. The length-fixing plate 10 is slidably inserted into the workbench 1 via the adjusting rod 8 and locked by the locking bolt 9. The two ends of the movable seat 12 are arranged to extend upward through the length-fixing plate 10. The cylinder 11 is installed in the middle of the movable seat 12, and its output end is fixedly connected to the bottom of the length-fixing plate 10.

[0030] According to the length of the pin, push and pull the length plate 10 to the appropriate position, and rotate the locking bolt 9 to lock the adjusting rod 8 on the workbench 1. The length plate 10 has an inverted trapezoidal opening on the side facing the workbench 1 that is horizontally corresponding to the inverted trapezoidal opening of the workbench 1. The raw material for making the pin can be placed in the two placement slots in the middle of the workbench 1, so that one end of the raw material abuts against the length plate 10. The pushing part 4 includes a moving part 401, a limiting end 402 and a baffle 403. The baffle 403 consists of two baffles that are respectively fixed to the bottom of the moving part 401 and are respectively set to correspond to the two inverted trapezoidal openings of the workbench 1. The limiting end 402 is rotatably mounted on the moving part 401. The drive motor 2 drives the pushing part 4 to move through the lead screw 3, so that the baffle 403 fits against the other end of the pin. Rotate the limiting end 402 so that its bottom applies pressure to the pin.

[0031] The limiting part 6 includes a fixed base 601, an adjusting bolt 602, and a second pressure application part 603. The bottom of the fixed base 601 is provided with a slot corresponding to the inverted trapezoidal opening of the workbench 1. The second pressure application part 603 slides up and down along the slot and is rotatably connected to the fixed base 601 through the adjusting bolt 602. The rotatable adjusting bolt 602 applies pressure to the pin through the second pressure application part 603.

[0032] The pressure-applying component 5 includes a slide rod 501, a bolt 502, and a pressure-applying part 503. The two ends of the slide rod 501 slide along the slide rail 7 respectively. The pressure-applying part 503 is rotatably mounted on the slide rod 501 by the bolt 502. Because the raw material is long, in order to ensure the stability of the raw material pushing process and the stability of cutting, the slide rod 501 can be manually pushed to move along the slide rail 7, and the bolt 502 can be rotated to push the pressure-applying part 503 to apply pressure to the position corresponding to the pin.

[0033] After the raw materials are positioned, the external cutting machine located near the length plate 10 can be started. (It should be noted that the external cutting machine is located directly above the two raw materials to facilitate downward movement and to cut the two raw materials at the same time.) The raw materials can be cut downward. The lower end of the worktable 1 is also equipped with a receiving plate 13 located below the length plate 10. After the cutting is completed, the cylinder 11 can be driven to push the cut pin upward with the movable seat 12 to ensure that the pin falls onto the receiving plate 13 after being cut and is collected.

[0034] Subsequently, the drive motor 2 can drive the pusher 4 to move along the slide rail 7 via the lead screw 3. The pusher 4 pushes the raw material to the fixed length plate 10 via the baffle 403. Then, the external cutting machine can cut the raw material downward at the corresponding position.

[0035] This device can simultaneously cut two raw materials for making pins using a single cutting machine, automatically achieving cutting and length setting, effectively improving cutting efficiency. The pusher 4, pressure applicator 5, and limiter 6 can conveniently limit the raw materials while pushing them for length setting.

[0036] The first pressure unit 503 consists of a connecting frame and rollers. The bolt 502 is rotatably connected to the connecting frame of the first pressure unit 503, and the rollers are rotatably mounted on the connecting frame. The second pressure unit 603 also consists of a connecting frame and rollers. The adjusting bolt 602 is rotatably connected to the connecting frame of the second pressure unit 603, and the rollers are rotatably mounted on the connecting frame, so as to limit the position of the raw materials and facilitate pushing and cutting to a fixed length.

[0037] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
