Description

Technical Field

[0001] This utility model belongs to the field of ball head pin processing technology, and in particular relates to a ball head pin processing device. Background Technology

[0002] A ball joint is a mechanical connector that allows rotation and oscillation in three-dimensional space. It achieves omnidirectional motion through the cooperation of a ball and a socket, and is widely used in scenarios that require multi-angle hinges (such as automotive suspension, steering systems, and linkages in engineering machinery).

[0003] Traditional equipment lacks specialized clamping tools, which makes the ball head pins prone to shifting during the grinding process, resulting in over-grinding or defective products. In addition, when switching to different specifications of ball head pins, operators need to change the clamps, which is time-consuming, labor-intensive, and cumbersome, resulting in low overall processing efficiency. Therefore, we have proposed a ball head pin processing device. Utility Model Content

[0004] The purpose of this invention is to provide a processing device for ball head pins. Specifically, by setting up a clamping part, the ball head pin is inserted between three clamping blocks. Turning the handle clockwise causes the worm gear to rotate, and the turntable rotates counterclockwise around the center of the rotating housing. As the turntable rotates, the three moving blocks move closer together to clamp the ball head pin. After processing, turning the handle counterclockwise causes the worm gear to rotate the turntable clockwise, and the three moving blocks move further apart, releasing the clamp on the ball head pin. This method allows for quick and flexible clamping of ball head pins, and is simple to operate. It can clamp ball head pins of different specifications without requiring manual adjustment of the clamps. This solves the problem of existing processing devices lacking clamping components and requiring operators to change clamps when dealing with ball head pins of different specifications, resulting in low work efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0011] A clamping assembly, mounted inside the rotating housing, is used to clamp a ball-end pin; and

[0012] A rotating assembly, installed inside a rotating housing, is used to rotate a turntable;

[0014] Furthermore, the cleaning unit includes a scraping assembly installed inside the processing chamber, the scraping assembly being used to scrape off iron filings that fall to the bottom of the processing chamber;

[0015] A collection component, installed inside the housing, is used to collect iron filings in a centralized manner;

[0016] The collection component collects the falling iron filings after the scraping component is activated, preventing them from spilling into other parts of the box.

[0017] Furthermore, the clamping assembly includes several moving blocks, each of which has a moving shaft fixedly connected to its left side, and a clamping block fixedly connected to the side of each of the moving blocks that is close to each other. Several limiting clamping blocks are fixedly connected to the right side of the inner wall of the rotating shell, and limiting blocks are fixedly connected to the left side of each of the moving blocks.

[0018] The limiting clamp is slidably connected to the limiting block, and the limiting block also limits the movement of the moving block, so that the moving block remains stable during movement.

[0019] Furthermore, the rotating assembly includes a handle, a worm gear is fixedly connected to the side of the handle near the rotating housing, a support block is fixedly connected to the inner wall of the rotating housing, three sliding grooves are opened inside the turntable, the moving shaft is slidably limited to the sliding grooves, three limiting posts are fixedly connected to the left side of the inner wall of the rotating housing, and three sliding grooves are opened inside the turntable, the sliding grooves are slidably limited to the limiting posts.

[0020] The worm gear is rotatably connected to the support block, which serves to support and limit the worm gear, making its rotation smoother and more stable. Meanwhile, a limit ring is fixedly connected to the right side of the limit post, which serves to limit the worm gear.

[0021] Furthermore, the scraping assembly includes a second motor, two cleaning slots are provided at the bottom of the processing chamber, a bidirectional lead screw is fixedly connected to the front output end of the second motor via a coupling, a moving ring is slidably connected to the outer surface of the bidirectional lead screw, a cleaning strip is fixedly connected to the left side of the moving ring, two cleaning blades are fixedly connected to the bottom of the cleaning strip, and a cleaning brush is fixedly connected to the bottom of the cleaning strip.

[0022] The cleaning strip has a fixed connection to a limiting protrusion on its left side, and a limiting groove is formed on the left side of the inner wall of the processing chamber. The limiting protrusion and the limiting groove slide and limit each other, and the limiting groove also supports the cleaning strip.

The cleaning blade pushes the iron filings forward, and several cleaning brushes sweep away any missed iron filings. When the cleaning strip moves to the cleaning groove at the front, the iron filings fall into the housing and into the drawer. When the moving ring reaches its limit position, it moves in the opposite direction to clean the processing chamber again. This process is repeated to clean a large amount of iron filings at the bottom of the processing chamber. This method allows for convenient and quick cleaning of iron filings generated during processing, eliminating the need for manual cleaning by workers and reducing workload.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0040] Please see Figures 1-7 As shown, this utility model is a processing device for ball-end pins, including a housing 1, a dustproof door 11 installed on the front of the housing 1, a locking block 12 installed on the front of the dustproof door 11, a locking frame 13 installed on the front of the housing 1, a processing chamber 14 arranged inside the housing 1, a cutting machine 15 installed on the top of the processing chamber 14, and also including:

[0041] Clamping part 2, installed inside housing 1, is used to clamp workpieces; and

[0042] Cleaning unit 3 is installed inside the processing chamber 14 and is used to clean up the iron filings generated during processing.

[0043] The locking block 12 and the locking frame 13 work together to lock the dustproof door 11, and the dustproof door 11 has an observation window on the front.

[0044] The clamping part 2 includes a ball head pin 16. A motor 21 is fixedly connected to the left side of the inner wall of the housing 1 by bolts. A rotating shell 22 is fixedly connected to the output end of the motor 21 on the right side. A turntable 241 is installed inside the rotating shell 22.

[0045] Clamping assembly 23, installed inside rotating housing 22, is used to clamp ball head pin 16; and

[0046] Rotating assembly 24 is installed inside rotating housing 22 and is used to rotate turntable 241.

[0047] The clamping component 23 adopts a three-point clamping method, which provides a more uniform clamping force and reduces local stress concentration.

[0048] The cleaning unit 3 includes a scraping component 31, which is installed inside the processing chamber 14 and is used to scrape off iron filings that fall to the bottom of the processing chamber 14.

[0049] Collection component 32 is installed inside the housing 1 and is used to collect iron filings in a centralized manner.

[0050] The collecting component 32 collects the falling iron filings after the scraping component 31 is activated, preventing the iron filings from falling into other parts of the box 1.

[0051] The clamping assembly 23 includes several moving blocks 231. Each of the several moving blocks 231 has a moving shaft 232 fixedly connected to its left side. Each of the several moving blocks 231 has a clamping block 233 fixedly connected to the side of each moving block 231 that is close to each other. A number of limiting clamping blocks 234 are fixedly connected to the right side of the inner wall of the rotating shell 22. Each of the several moving blocks 231 has a limiting block 235 fixedly connected to its left side.

[0052] The limiting clamp 234 is slidably connected to the limiting block 235, and the limiting block 235 also limits the moving block 231, so that the moving block 231 remains stable during movement.

[0053] The rotating assembly 24 includes a handle 242, a worm gear 243 fixedly connected to the side of the handle 242 near the rotating housing 22, a support block 244 fixedly connected to the inner wall of the rotating housing 22, three sliding grooves 245 inside the turntable 241, a moving shaft 232 slidingly limiting its engagement with the sliding grooves 245, three limiting posts 247 fixedly connected to the left side of the inner wall of the rotating housing 22, and three sliding grooves 246 inside the turntable 241 slidingly limiting their engagement with the limiting posts 247; when the ball-head pin 16 is inserted between the three clamping blocks 233, the handle 242 is rotated clockwise. The worm gear 243 is driven to rotate, and the turntable 241 rotates counterclockwise around the center of the rotating shell 22. When the turntable 241 rotates, the three moving blocks 231 move closer to each other to clamp the ball head pin 16. After processing, the handle 242 is turned counterclockwise, and the worm gear 243 drives the turntable 241 to rotate clockwise. The three moving blocks 231 move further apart to release the clamping of the ball head pin 16. This method can clamp the ball head pin 16 quickly and flexibly. At the same time, it is simple to operate and can clamp ball head pins 16 of different specifications without the need for operators to change the clamps.

[0054] The worm gear 243 is rotatably connected to the support block 244, which serves to support and limit the rotation of the worm gear 243, making the rotation smoother and more stable. Meanwhile, a limit ring is fixedly connected to the right side of the limit post 247, which serves to limit the rotation.

[0055] The scraping assembly 31 includes a second motor 312. The bottom of the processing chamber 14 has two cleaning grooves 311. The front output end of the second motor 312 is fixedly connected to a bidirectional lead screw 313 via a coupling. A moving ring 314 is slidably connected to the outer surface of the bidirectional lead screw 313. A cleaning strip 315 is fixedly connected to the left side of the moving ring 314. Two cleaning blades 318 are fixedly connected to the bottom of the cleaning strip 315. A cleaning brush 319 is fixedly connected to the bottom of the cleaning strip 315.

[0056] Among them, the cleaning strip 315 is fixedly connected to the left side of the limiting protrusion 316, and the processing chamber 14 has a limiting groove 317 on the left side of the inner wall. The limiting protrusion 316 and the limiting groove 317 slide and limit each other, while the limiting groove 317 also supports the cleaning strip 315.

[0057] Two collection plates 321 are fixedly connected to the inner wall of the box 1. A drawer 322 is inserted into the bottom of the box 1. A handle 323 is fixedly connected to the right side of the drawer 322. The start motor 312 drives the bidirectional lead screw 313 to rotate, the moving ring 314 moves forward, and moves the cleaning strip 315 together. The cleaning blade 318 pushes the iron filings forward. Several cleaning brushes 319 sweep away the missed iron filings. When the cleaning strip 315 moves to the cleaning groove 311 in front, the iron filings will fall into the box 1 and into the drawer 322. When the moving ring 314 moves forward to the limit position, it will move in the opposite direction to clean the processing chamber 14 again. This process is repeated to clean a large amount of iron filings at the bottom of the processing chamber 14. This method can clean the iron filings generated during processing conveniently and quickly without the need for manual cleaning by the staff, thus reducing the workload.

[0058] Among them, the two collection plates 321 are set at an angle to guide the flow.

[0059] A specific application of this embodiment is as follows: During operation, the locking block 12 is pushed upwards to disengage it from the locking frame 13, thus releasing the lock on the dustproof door 11. Then, the dustproof door 11 is opened, and the ball-head pin 16 is inserted between the three clamping blocks 233. At this time, the handle 242 is turned clockwise, causing the worm gear 243 to rotate. Because the limiting post 247 is slidably connected to the slide groove 246, and the limiting post 247 is fixedly connected to the rotating shell 22, when the worm gear 243 rotates, it will pass through the turntable 241. The worm gear teeth of the ring drive the turntable 241 to rotate counterclockwise around the center of the rotating shell 22. The moving shaft 232 on the left side of the moving block 231 slides within the slide groove 245. The limiting block 235 on the left side of the moving block 231 slides and is limited by the limiting clamping block 234. Therefore, when the turntable 241 rotates counterclockwise, the three moving blocks 231 will move closer to each other, clamping the ball pin 16 through the clamping block 233. Furthermore, the worm gear teeth of the worm 243 and the outer ring of the turntable 241 can achieve self-locking. Therefore, the clamping block 233 can firmly clamp the ball head pin 16. At this time, the motor 21 can be started to drive the rotating shell 22 to rotate, and then the cutting machine 15 is started. The cutting tool at the bottom of the cutting machine 15 processes the ball head pin 16. The cutting machine 15 is composed of the X-axis and 2-axis feed system and the control system. The feed system is used to control the movement of the tool. The control system adopts (CNC) computer programming control. During processing, the dust door 11 can be closed and the locking block 12 can be pushed down to make the locking block 12 enter the locking frame 13 to lock the dust door 11 and prevent cutting chips from flying out. At the same time, the operator can check the processing progress through the observation window on the dust door 11. After processing is completed, the motor 21 is turned off, and then the throttle 242 is turned counterclockwise. The worm gear 243 will drive the turntable 241 to rotate clockwise. At this time, the three moving blocks 231 will move away from each other, releasing the clamping of the ball head pin 16. Then the processed ball head pin 16 can be taken out.

[0060] After prolonged operation, a large amount of iron filings will accumulate at the bottom of the processing chamber 14, requiring cleaning. At this time, the motor 312 is started, driving the bidirectional lead screw 313 to rotate. The moving ring 314 moves forward, along with the cleaning strip 315. The cleaning blade 318 at the bottom of the cleaning strip 315 pushes the iron filings forward, while several cleaning brushes 319 sweep away any missed iron filings. When the cleaning strip 315 moves to the cleaning groove 311 at the front, the iron filings fall into the housing 1. The collecting plate 321 then guides the iron filings into the drawer 322. When the moving ring 314 reaches its maximum position, it moves in the opposite direction, cleaning the bottom of the processing chamber 14 again. This process is repeated to clean the large amount of iron filings at the bottom of the processing chamber 14. When the drawer 322 needs cleaning, pull the handle 323 to the right to completely remove the drawer 322 from the housing 1. Then empty the iron filings from the drawer 322 and reinstall it.
