Description

Technical Field

[0001] This invention relates to the field of textile needle technology, and in particular to an intelligent precision machining device for abrasion-resistant sock needles. Background Technology

[0002] In the textile industry, sock needles are a key component, and their abrasion resistance and precision directly affect the quality and production efficiency of socks. Currently, with the continuous improvement of the automation level of textile machinery, higher requirements are being placed on the processing precision and abrasion resistance of sock needles. Traditional sock needle processing methods mostly rely on manual operation, which has problems such as low efficiency and difficulty in guaranteeing precision. Although some automated equipment has been gradually applied to sock needle processing in recent years, there is still considerable room for improvement in abrasion resistance and intelligence. The development of related technologies has promoted the overall progress of the textile industry, but how to further improve the processing precision and abrasion resistance of sock needles remains an urgent problem to be solved.

[0003] In existing technologies, the processing of sock needles mainly employs the following methods: The first is the traditional manual grinding method, which involves manually operating a grinding wheel to grind the sock needles. The advantage is flexible operation, but the disadvantages are low efficiency and difficulty in guaranteeing precision. The second is the semi-automatic grinding machine method, which processes the sock needles using a semi-automatic grinding machine. The advantage is improved processing efficiency, but the disadvantage is insufficient wear resistance. The third is the CNC grinding machine method, which uses a CNC system to control the grinding machine. The advantage is high precision, but the disadvantages are high equipment cost and complex operation. Each method has its own advantages and disadvantages, but none can fully meet the high requirements of the modern textile industry for sock needles.

[0004] The main drawbacks of existing technologies are low processing efficiency, difficulty in guaranteeing precision, insufficient wear resistance, high equipment cost, and complex operation. Traditional manual grinding and semi-automatic grinding methods are significantly insufficient in terms of efficiency and precision. Although CNC grinding improves precision, the equipment cost and operational complexity limit its widespread application. In addition, existing technologies have limited improvement in wear resistance and cannot meet the high requirements of the modern textile industry for sock needles. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent precision machining device for wear-resistant sock needles, which solves the problems of low machining accuracy and wear resistance, as well as high equipment cost and operation complexity in existing precision machining of sock needles.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A wear-resistant intelligent precision machining device for sock needles includes a base. An adjustment mechanism is provided on the rear side of the top of the base. The adjustment mechanism is used to adjust the grinding speed and angle to achieve high-precision machining of the sock needles. A clamping mechanism is provided on the front side of the top of the base. The clamping mechanism is used to clamp the sock needles to prevent them from shifting during grinding and affecting the machining accuracy. A loading and unloading mechanism is provided on the top of the base. The loading and unloading mechanism is used to quickly assemble and disassemble the grinding tools to meet different processing needs. The adjustment mechanism includes a sliding platform slidably connected to the top center of the base. A turntable is rotatably connected to the rear top of the sliding platform. A drive motor is fixedly connected to the top of the turntable. A transmission rod is fixedly connected to the output end of the drive motor. A support base is fixedly connected to the front top of the sliding platform. The transmission rod is slidably connected to the inner wall of the support base. A grinding head is slidably connected to the front end of the transmission rod. A bracket is fixedly connected to the rear top of the base. A slider is slidably connected to the outer side of the bracket. A swing arm is rotatably connected to the bottom of the slider. A friction pad is fixedly connected to the front side of the swing arm. A connecting rod is fixedly connected to the rear side of the drive motor. The swing arm is rotatably connected to the connecting rod. A limit component is provided at the bottom of the sliding platform. A sliding component is provided at the top center of the base. A stabilizing component is provided on the inner side of the sliding platform.

[0007] Through the above technical solution, when the swing arm rotates, it drives the drive motor and transmission rod to deflect the grinding head through the connecting rod, thereby realizing the grinding angle of the grinding head and improving the processing accuracy. When the sliding platform moves, it drives the grinding head to perform comprehensive processing on the sock needle, ensuring that the surface roughness is the same throughout the entire length of the sock needle, thereby improving the wear resistance of the sock needle.

[0008] Preferably, the clamping mechanism includes a fixed frame, which is fixedly connected to the front top of the base. A rotating rod is rotatably connected to the inner side of the fixed frame. The right end of the rotating rod passes through the fixed frame and is fixedly connected to a knob. Two discs are fixedly connected to the outer side of the rotating rod. An eccentric shaft is fixedly connected to the outer side of the discs. A connecting rod is rotatably connected to the outer side of the eccentric shaft. The top end of the connecting rod passes through the fixed frame and is fixedly connected to a lower clamping jaw. Upper clamping jaws are fixedly connected to the left and right sides of the top of the fixed frame. A fixing component is provided on the outer side of the lower clamping jaw.

[0009] With the above technical solution, when the knob is turned, the rotating rod drives the disc to rotate, which in turn drives the eccentric shaft to rotate, thereby moving the connecting rod and the lower clamping jaw. The lower and upper clamping jaws firmly hold the sock needles, preventing the movement of the sock needles during processing from affecting the processing quality.

[0010] Preferably, the loading and unloading mechanism includes a locking groove, which is formed at the inner front end of the transmission rod. Two locking blocks are fixedly connected to the outer side of the grinding head. A locking spring is fixedly connected to the inner rear side of the transmission rod. Multiple positioning springs are fixedly connected to the inner perimeter of the transmission rod. Ball bearings are fixedly connected to the outer side of the positioning springs. The ball bearings are slidably connected to the inner wall of the transmission rod. A shock-absorbing component is provided at the bottom of the base.

[0011] The above technical solution uses a locking spring to firmly attach the locking block to the surface of the locking groove, thereby fixing the grinding head. The positioning spring and ball bearings enable the grinding head to be automatically aligned and positioned when it is installed, thereby further improving the processing accuracy of sock needles.

[0012] Preferably, the limiting component includes limiting blocks, two limiting blocks are fixedly connected to the bottom front and rear sides of the sliding platform respectively, and limiting grooves are provided on the top front and rear sides of the base. The two limiting blocks are slidably connected to the outside of the corresponding limiting grooves respectively.

[0013] The above technical solution restricts the movement direction of the sliding platform by using limiting grooves and limiting blocks, so that it can only move left and right along the base, thus preventing the sliding platform from shifting during operation and affecting the quality of sock needle processing.

[0014] Preferably, the sliding assembly includes a slide groove, which is formed at the top center of the base. A lead screw is rotatably connected to the outer side of the slide groove. A second drive motor is fixedly connected to the right side of the base. The output end of the second drive motor passes through the base and is fixedly connected to the lead screw. A first slider is threadedly connected to the outer side of the lead screw. The first slider is fixedly connected to the bottom center of the sliding platform. A through hole is formed on the inner bottom side of the sliding platform. A protective plate is fixedly connected to the top center of the base. The protective plate is slidably connected to the through hole.

[0015] Through the above technical solution, the second drive motor drives the lead screw to rotate, and under the restriction of the inner wall of the base, the first slider can only move along the lead screw axis, thereby driving the sliding platform to move on the base.

[0016] Preferably, the stabilizing component includes a mounting slot located inside the rear side of the sliding platform, and a spring is rotatably connected to the outer side of the mounting slot. The two ends of the spring are fixedly connected to the turntable and the sliding platform, respectively.

[0017] With the above technical solution, when the drive motor deflects, it will drive the turntable to rotate synchronously. The spring force of the clockwork spring stabilizes the turntable and avoids excessive deflection.

[0018] Preferably, the adjustment mechanism further includes rollers, and a plurality of rollers are rotatably connected to the inner periphery of the slider two, and the rollers are rotatably connected to the bracket.

[0019] The above technical solution transforms the sliding friction between slider 2 and the bracket into rolling friction between the roller and the bracket, thereby making slider 2 move more smoothly.

[0020] Preferably, the fixing component includes a rubber pad one, two fixing brackets are respectively fixedly connected to the top of the corresponding lower jaws, and a rubber pad two is fixedly connected to the bottom of the upper jaw.

[0021] Through the above technical solution, when the upper and lower jaws clamp the sock needles, the friction between the upper jaws and the sock needles is increased by rubber pad one and rubber pad two, making the clamping of the sock needles more secure. At the same time, the rubber pads can reduce scratches on the surface of the sock needles.

[0022] Preferably, the clamping mechanism further includes a photoelectric sensor, which is fixedly connected to the top front left side of the sliding platform.

[0023] The above technical solution uses photoelectric sensors to monitor the processing status of sock needles in real time and automatically adjusts grinding parameters through a feedback control system, thereby further improving processing accuracy and efficiency, but the equipment cost is relatively high.

[0024] Preferably, the shock absorption assembly includes support legs, two of which are fixedly connected to the top left and right sides of the base, and a buffer pad is fixedly connected to the bottom of the support legs.

[0025] Through the above technical solution, the support legs are used to support the entire device, and the buffer pad absorbs the vibration transmitted to the device from the outside, reducing the impact of external vibration on the device's operating status.

[0026] In summary, the present invention has at least one of the following beneficial technical effects: 1. This invention achieves high-speed rotary grinding by utilizing a combination of a drive motor, transmission rod, and grinding head. Simultaneously, the adjustable swing arm and connecting rod allow for flexible control of the grinding angle. Combined with the precise movement of the sliding platform, this enables uniform and controllable grinding of the entire length of the sock needle, thereby improving the processing accuracy and surface consistency of the sock needle, enhancing its wear resistance, and ensuring the continuity and controllability from power output to final grinding execution. This allows the device to adapt to the processing needs of sock needles of different specifications and complex contours.

[0027] 2. This invention employs a linkage structure consisting of a knob, an eccentric shaft, and a connecting rod, enabling rapid and stable clamping of sock needles. The self-locking characteristic of the eccentric structure ensures reliable clamping force, while the rubber pad increases friction and protects the needle surface, preventing needle displacement and surface damage during processing. This provides a stable foundation for high-precision grinding, simplifies the operation process, and improves clamping efficiency. Furthermore, by optimizing the force distribution, it reduces potential clamping deformation or surface indentations on precision workpieces while ensuring secure clamping, thus guaranteeing the accuracy of the processing datum and the final product quality.

[0028] 3. This invention, through the use of a quick-connect structure consisting of a locking block, locking spring, positioning spring, and ball bearings, achieves rapid disassembly and assembly of the grinding head and automatic centering and positioning. This meets the requirements for rapid tool changes under different processing needs, and ensures the coaxiality and stability of the grinding head installation. This further guarantees processing accuracy and ease of operation, shortens downtime caused by tool changes, and improves the overall utilization rate of the equipment. Its built-in positioning and locking mechanism also fundamentally avoids processing deviations caused by manual installation errors, ensuring the consistency of processing parameters for each workpiece in mass production.

[0031] The following is in conjunction with the appendix Figure 1 - Appendix Figure 8 The present invention will be further described in detail below.

[0032] This invention provides an intelligent precision machining device for wear-resistant sock needles, including a base 1. An adjustment mechanism 2 is provided on the rear side of the top of the base 1. The adjustment mechanism 2 is used to adjust the grinding speed and angle to achieve high-precision machining of the sock needles. A clamping mechanism 3 is provided on the front side of the top of the base 1. The clamping mechanism 3 is used to clamp the sock needles to prevent the sock needles from shifting during grinding and affecting the machining accuracy. A loading and unloading mechanism 4 is provided on the top of the base 1. The loading and unloading mechanism 4 is used to quickly disassemble and assemble the grinding tools to meet different processing needs. The adjustment mechanism 2 includes a sliding platform 21, which is slidably connected to the top center of the base 1. The sliding platform 21 moves left and right along the base 1, driving the grinding part to move as a whole, thereby performing comprehensive grinding of the sock needles. A turntable 22 is rotatably connected to the top rear side of the sliding platform 21. A drive motor 23 is fixedly connected to the top of the turntable 22. A transmission rod 24 is fixedly connected to the output end of the drive motor 23. When the drive motor 23 starts, it drives the transmission rod 24 to rotate. A support base 25 is fixedly connected to the top front side of the sliding platform 21. The transmission rod 24 is slidably connected to the inner wall of the support base 25. The base 25 supports the transmission rod 24 and allows the transmission rod 24 to deflect. A grinding head 26 is slidably connected to the front end of the transmission rod 24. When the transmission rod 24 rotates, it drives the grinding head 26 to rotate synchronously. The high-speed rotating grinding head 26 performs precision machining on the sock needles. A bracket 215 is fixedly connected to the top rear side of the base 1. A slider 210 is slidably connected to the outer side of the bracket 215. A swing arm 211 is rotatably connected to the bottom of the slider 210. A friction pad 213 is fixedly connected to the front side of the swing arm 211. A connecting rod 212 is fixedly connected to the rear side of the drive motor 23. The swing arm 211 is rotatably connected to the connecting rod 212. When 211 rotates, it drives the connecting rod 212 to deflect synchronously, thereby causing the drive motor 23, transmission rod 24, and grinding head 26 to deflect synchronously, thus adjusting the grinding angle. When the swing arm 211 rotates, the friction pad 213 is continuously compressed by the swing arm 211 and connecting rod 212, and the resulting friction prevents the swing arm 211 from rotating accidentally. When the sliding platform 21 moves, the sliding of the slider 210 on the bracket 215 allows the swing arm 211 to move with the sliding platform 21, thereby ensuring the stability of the angle after deflection. The bottom of the sliding platform 21 is provided with a limit component 27, and the top center of the base 1 is provided with a sliding component 28. The inner side of the platform 21 is provided with a stabilizing component 29; the adjustment mechanism 2 also includes rollers 214, multiple rollers 214 are rotatably connected to the inner periphery of the slider 210, the rollers 214 are rotatably connected to the bracket 215, the rollers 214 reduce the friction between the slider 210 and the bracket 215, thereby making the slider 210 slide more smoothly. The base 1 is made of high-strength aluminum alloy, the bracket 215 is made of stainless steel, the sliding platform 21 is made of wear-resistant plastic, the grinding head 26 is made of diamond, the drive motor is a servo motor, the connecting rod 212 is made of carbon steel, and the swing arm 211 is made of titanium alloy. Specifically, the sliding platform 21 moves laterally along the top of the base 1. A drive motor 23 is fixed to the turntable 22 on the rear side of the sliding platform 21, and its output end is connected to a transmission rod 24. A grinding head 26 is mounted on the front end of the transmission rod 24. When the drive motor 23 starts, it drives the transmission rod 24 and the grinding head 26 to rotate at high speed, performing grinding on the sock needles. The support base 25 provides radial support to the transmission rod 24 while allowing it to deflect within a certain angle range. The swing arm 211 is rotatably connected to the slider 210, which slides along the bracket 215. The connecting rod 212 connects to the swing arm 21. 1. Drive motor 23. When the swing arm 211 rotates, the connecting rod 212 drives the drive motor 23 and the transmission rod 24 to deflect synchronously, thereby changing the processing angle of the grinding head 26. The friction pad 213 is pressed and generates static friction when the swing arm 211 rotates, thereby providing position holding force for the swing arm 211 and preventing the swing arm 211 from deflecting unexpectedly during operation. The slider 210 contacts the bracket 215 through the inner roller 214, reducing sliding resistance and allowing the swing arm 211 to move synchronously and smoothly with the sliding platform 21, ensuring stability after angle adjustment.

[0033] The clamping mechanism 3 includes a fixed frame 31, which is fixedly connected to the front top of the base 1. A rotating rod 32 is rotatably connected to the inner side of the fixed frame 31. The right end of the rotating rod 32 passes through the fixed frame 31 and is fixedly connected to a knob 33. The knob 33 controls the rotation of the rotating rod 32. Two discs 34 are fixedly connected to the outer side of the rotating rod 32. When the rotating rod 32 rotates, it drives the discs 34 to rotate. An eccentric shaft 35 is fixedly connected to the outer side of the discs 34. The eccentric shaft 35 is located at the eccentric position of the discs 34. When the discs 34 rotate, they drive the eccentric shaft 35 to rotate synchronously. A connecting rod is rotatably connected to the outer side of the eccentric shaft 35. 36. Due to the restriction of the inner wall of the fixed frame 31, the connecting rod 36 can only move up and down along the fixed frame 31. When the eccentric shaft 35 rotates, it drives the connecting rod 36 to move up and down along the fixed frame 31. The top of the connecting rod 36 passes through the fixed frame 31 and is fixedly connected to the lower clamping jaw 37. When the connecting rod 36 moves, it drives the lower clamping jaw 37 to move synchronously. The top left and right sides of the fixed frame 31 are fixedly connected to the upper clamping jaw 38. When the lower clamping jaw 37 is close to the upper clamping jaw 38, the self-locking property of the eccentric cam makes the lower clamping jaw 37 stable, thereby realizing the stable clamping of the sock needle. The outer side of the lower clamping jaw 37 is provided with a fixing component 39. Specifically, the fixing frame 31 is fixed to the front of the top of the base 1, the rotating rod 32 is rotatably connected to the inner side of the fixing frame 31, the disc 34 is fixed to the outer side of the rotating rod 32, the eccentric shaft 35 is fixed to the eccentric position of the disc 34, one end of the connecting rod 36 is rotatably connected to the eccentric shaft 35, and the other end is fixed to the lower jaw 37. The upper jaw 38 is fixed to the top of the fixing frame 31. Rotating the knob 33 drives the rotating rod 32 to rotate, and the rotating rod 32 drives the disc 34 to rotate synchronously. The rotation of the disc 34 drives the eccentric shaft 34 to rotate. The shaft 35 moves in a circular motion around the axis of the rotating rod 32. The motion of the eccentric shaft 35 is converted into the vertical lifting and lowering of the lower jaw 37 through the connecting rod 36. Due to the restriction of the movement direction of the connecting rod 36 by the inner wall of the fixed frame 31, the connecting rod 36 can only move in a straight line along the preset path of the inner wall of the fixed frame 31. When the lower jaw 37 rises to contact and press against the upper jaw 38, the sock needle is clamped between the two jaws. At this time, the eccentric shaft 35 achieves stable maintenance of the clamping state through the self-locking characteristic of the eccentric structure.

[0034] The loading and unloading mechanism 4 includes a locking groove 41, which is located at the inner front end of the transmission rod 24. Two locking blocks 42 are fixedly connected to the outer side of the grinding head 26. When installing the grinding head 26, the locking blocks 42 are aligned with the protrusions on the locking groove 41 and inserted. A locking spring 43 is fixedly connected to the inner rear side of the transmission rod 24. When the grinding head 26 is inserted, it continuously compresses the locking spring 43. When fully inserted, the grinding head 26 is rotated to displace the locking blocks 42 from the protrusions on the locking groove 41. Under the elastic force of the locking spring 43, the locking block 42 is tightly attached to the inner surface of the locking groove 41, thereby achieving the fixed installation of the grinding head 26. Multiple positioning springs 44 are fixedly connected to the inner side of the transmission rod 24, and ball bearings 45 are fixedly connected to the outer side of the positioning springs 44. The ball bearings 45 are slidably connected to the inner wall of the transmission rod 24. When the grinding head 26 is inserted, it can achieve automatic centering and positioning under the action of the ball bearings 45 and the positioning springs 44. The bottom of the base 1 is provided with a shock-absorbing component 46. Specifically, the locking groove 41 is formed at the inner front end of the transmission rod 24, the locking block 42 is fixed to the outer side of the grinding head 26, the locking spring 43 is installed inside the rear side of the transmission rod 24, and the positioning spring 44 and the balls 45 are distributed circumferentially along the inner wall of the transmission rod 24. During installation, the locking block 42 of the grinding head 26 is aligned with the entrance of the locking groove 41 and inserted. During the insertion process, the end of the grinding head 26 contacts and compresses the locking spring 43, while the outer wall of the grinding head 26 contacts multiple balls 45. Under the pressure of the positioning spring 44, the balls 45 roll and grind against the grinding head. The grinding head 26 generates a radial constraint force, thereby automatically adjusting the axis of the grinding head 26 to coincide with the axis of the transmission rod 24, realizing automatic centering and positioning during the installation process. When the grinding head 26 is fully inserted, the grinding head 26 is rotated to displace the locking block 42 from the entrance of the locking groove 41. At this time, the restoring force of the locking spring 43 pushes the grinding head 26 to move outward of the transmission rod 24, so that the locking block 42 is pressed tightly against the inner wall of the locking groove 41, thereby fixing the grinding head 26 on the transmission rod 24. To disassemble, simply rotate in the opposite direction and pull out the grinding head 26.

[0035] The limiting component 27 includes limiting blocks 272, which are fixedly connected to the front and rear sides of the bottom of the sliding platform 21, respectively. Limiting grooves 271 are provided on the front and rear sides of the top of the base 1. The two limiting blocks 272 are slidably connected to the outer sides of the corresponding limiting grooves 271. The limiting grooves 271 and the limiting blocks 272 restrict the movement direction of the sliding platform 21, ensuring that the sliding platform 21 can only move left and right along the base 1. This prevents the sliding platform 21 from shifting during operation, which would affect the quality of the sock needle processing. The sliding assembly 28 includes a slide groove 281, which is located at the top center of the base 1. A lead screw 282 is rotatably connected to the outer side of the slide groove 281. A second drive motor 284 is fixedly connected to the right side of the base 1. The output end of the second drive motor 284 passes through the base 1 and is fixedly connected to the lead screw 282. A first slider 283 is threadedly connected to the outer side of the lead screw 282. The first slider 283 is fixedly connected to the bottom center of the sliding platform 21. A through hole 286 is provided on the bottom side of the sliding platform 21. A protective plate 285 is fixedly connected to the top center of the base 1. The protective plate 285 is slidably connected to the through hole 286. When the drive motor 284 starts, it drives the lead screw 282 to rotate. Under the restriction of the inner wall of the base 1, the slider 283 can only move along the axial direction of the lead screw 282. When the lead screw 282 rotates, it drives the slider 283 to move, thereby driving the sliding platform 21 to move synchronously through the slider 283. The protective plate 285 is used to prevent the debris generated during processing from entering the slide groove 281 and causing the lead screw 282 to rotate. The stabilizing component 29 includes a mounting slot 291, which is located inside the rear side of the sliding platform 21. A spring 292 is rotatably connected to the outside of the mounting slot 291. The two ends of the spring 292 are fixedly connected to the turntable 22 and the sliding platform 21, respectively. When the drive motor 23 deflects, it will drive the turntable 22 to rotate synchronously. The spring force of the spring 292 resists the force of the connecting rod 212, so that the turntable 22 can remain stable after deflection and avoid excessive deflection. Specifically, the limiting block 272 is fixed to the bottom of the sliding platform 21, and the limiting groove 271 is opened at the top of the base 1. The limiting block 272 is embedded in the limiting groove 271 and forms a sliding fit, thereby constraining the sliding platform 21 to move only left and right along the limiting groove 271, preventing the sliding platform 21 from deviating during movement, and providing a stable path reference for grinding. The slide groove 281 is opened at the top center of the base 1, and the lead screw 282 is installed inside the slide groove 281. The second drive motor 284 is fixed to the right side of the base 1, and the output end of the second drive motor 284 is connected to the lead screw 282. The first slider 283 forms a threaded fit with the lead screw 282, and the first slider 283 is fixed to the bottom of the sliding platform 21. The protective plate 285 is fixed to the top of the base 1, passes through the through hole 286 of the sliding platform 21, and plays an auxiliary support and guiding role for the platform. When motor 284 starts, it drives lead screw 282 to rotate. The rotational motion of lead screw 282 is converted into linear motion of slider 283 along the axial direction of slide groove 281. Slider 283 drives sliding platform 21 to move synchronously. This transmission method realizes precise control of platform position. Protective plate 285 is used to prevent debris generated during processing from entering slide groove 281 and causing lead screw 282 to jam. Spring 292 is installed in mounting groove 291 of sliding platform 21. One end of spring 292 is connected to sliding platform 21, and the other end is connected to turntable 22. When drive motor 23 drives transmission rod 24 to deflect, turntable 22 rotates accordingly and winds or stretches spring 292. The torque generated by spring 292 is balanced with the deflection force, so that turntable 22 can remain stable after deflection, ensuring the stability of grinding angle.

[0036] The fixing component 39 includes a first rubber pad 391, two fixing brackets 31 are respectively fixedly connected to the top of the corresponding lower gripper 37, and a second rubber pad 392 is fixedly connected to the bottom of the upper gripper 38. When the upper gripper 38 and the lower gripper 37 clamp the sock needle, the friction between the upper gripper 38 and the sock needle is increased by the first rubber pad 391 and the second rubber pad 392, making the clamping of the sock needle more secure. At the same time, the rubber pads can reduce the scratches on the surface of the sock needle. The clamping mechanism 3 also includes a photoelectric sensor 310, which is fixedly connected to the top front end of the sliding platform 21. On the left, the photoelectric sensor 310 is used to monitor the processing status of the sock needles in real time, and then adjusts the grinding parameters through the feedback control system to further improve the processing accuracy and efficiency, but the equipment cost is relatively high; the shock absorption component 46 includes support legs 461, two support legs 461 are fixedly connected to the top left and right sides of the base 1 respectively, and a buffer pad 462 is fixedly connected to the bottom of the support legs 461. The support legs 461 are used to support the entire device, and the buffer pad 462 is used to absorb the vibration transmitted to the device from the outside and reduce the impact of external vibration on the operating status of the device; Specifically, rubber pad 391 and rubber pad 392 are fixed to the clamping surfaces of the lower jaw 37 and upper jaw 38, respectively. When the two jaws close to clamp the sock needle, the rubber pads deform under pressure, increasing the contact area and friction between the clamping surface and the sock needle surface, thus enhancing the clamping force and preventing the sock needle from slipping or falling off during processing. Simultaneously, the elastic cushioning effect of the rubber material reduces the hard contact between the jaws and the sock needle surface, reducing the risk of surface scratches. A photoelectric sensor 310 is fixed to the top front end of the sliding platform 21. During processing, the photoelectric sensor 310 continuously detects the processing status of the sock needle and sends signals to the control system. The system judges the processing status based on signal changes and adjusts the speed of drive motor 23 or the moving speed of sliding platform 21 accordingly, realizing real-time monitoring and adaptive parameter adjustment of the processing process. However, the equipment cost is relatively high. Support legs 461 are fixed on both sides of the bottom of base 1 to provide support for the device. Buffer pads 462 are installed at the bottom of support legs 461. Buffer pads 462 are made of elastic material. When the device is subjected to vibration transmitted from the external environment, buffer pads 462 deform, absorb and dissipate some vibration energy, reduce the amplitude of vibration transmitted to base 1 and the moving parts above, and provide a stable mechanical foundation for grinding.

[0037] Working principle: The operator first places the sock needle to be processed in the fixed frame 31, positioning it between the upper clamping jaw 38 and the lower clamping jaw 37. The operator then rotates the knob 33 to rotate the rotating rod 32. The rotating rod 32 drives the two outer discs 34 to rotate synchronously. The eccentric shaft 35 on the disc 34 rotates with the disc 34 and makes an eccentric circular motion. Since the connecting rod 36 is rotatably connected to the eccentric shaft 35, and the connecting rod 36 is constrained by the inner wall of the fixed frame 31 and can only move up and down, the movement of the eccentric shaft 35 forces the connecting rod 36 to drive the lower clamping jaw 37 to move upward until the rubber pad 391 at the top of the lower clamping jaw 37 and the rubber pad 392 at the bottom of the upper clamping jaw 38 together clamp the sock needle. At this time, the eccentric shaft 35 generates a self-locking effect due to the eccentric structure, keeping the clamping state stable and preventing the sock needle from shifting during subsequent processing, thus ensuring consistent processing reference. When the drive motor 23 is started, its output shaft drives the transmission rod 24 to rotate at high speed. The grinding head 26 at the front end of the transmission rod 24 rotates accordingly. The operator can adjust the grinding angle by swinging the swing arm 211. When the swing arm 211 rotates, it drives the drive motor 23 and the turntable 22 fixed to it to deflect together via the connecting rod 212, thus changing the angle between the transmission rod 24 and the grinding head 26. During the swinging process, the friction pad 213 on the front side of the swing arm 211 generates static friction with the connecting rod 212, providing positioning for the swing arm 211. The retaining force prevents accidental angle changes. At the same time, the slider 210 slides along the bracket 215 via the inner roller 214, allowing the swing arm 211 to move synchronously with the sliding platform 21. This ensures that the relative position of the grinding head 26 and the sock needle is stable after angle adjustment. When the turntable 22 deflects, it stretches or winds the spring 292 installed inside the sliding platform 21. The restoring torque of the spring 292 balances the deflection force, further enhancing the stability of angle adjustment. This achieves precise and reliable adjustment of the grinding angle, adapting to the processing needs of sock needles in different parts and shapes. Start the second drive motor 284. The output shaft of the second drive motor 284 drives the lead screw 282 to rotate. The lead screw 282 and the slider 283 threaded on it form a helical transmission. The slider 283 moves along the axial direction of the lead screw 282 under the constraint of the inner wall of the base 1. The slider 283 is fixedly connected to the bottom of the sliding platform 21, thus driving the sliding platform 21 and the adjustment mechanism 2 on it to move left and right along the base 1. The limiting block 272 at the bottom of the sliding platform 21 is embedded in the limiting groove 271 at the top of the base 1, restricting the sliding platform 21 to move only in the horizontal direction, preventing it from shifting laterally, and ensuring the straightness accuracy of the grinding path. When the sliding platform 21 moves, the transmission rod 24 maintains stable rotation under the support of the support seat 25. The high-speed rotating grinding head 26 performs uniform grinding along the axial direction of the sock needle. By controlling the speed and direction of the second drive motor 284, the grinding stroke and speed can be precisely controlled, so that the grinding of the sock needle surface is uniform and the roughness is consistent, improving the overall wear resistance and dimensional accuracy of the sock needle. When the grinding head 26 needs to be replaced, the operator holds the grinding head 26 and rotates it in the opposite direction to align the locking block 42 with the locking protrusion of the locking groove 41. Under the restoring force of the locking spring 43, the grinding head 26 is pushed outward, allowing it to be removed for replacement. When installing the new grinding head 26, it is inserted into the front end of the transmission rod 24. During insertion, the outer wall of the grinding head 26 contacts multiple balls 45 pushed by the positioning spring 44. The balls 45 roll under the spring force and exert radial equal constraint on the grinding head 26, causing it to automatically center and ensuring that its axis coincides with the axis of the transmission rod 24. After insertion, the grinding head 26 is rotated to misalign the locking block 42 with the locking groove 41. The elastic force of the locking spring 43 presses the locking block 42 tightly against the inner wall of the locking groove 41, achieving a quick and stable installation and ensuring the installation accuracy and transmission reliability of the grinding head 26.
