Description

Technical Field

[0001] The present invention relates to the technical field of sewing machine head processing, and specifically relates to a grinding device and method for grinding the face of a sewing machine head. Background Technique

[0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material, so that one or more layers of sewing materials are interwoven or sewn together. Generally, a sewing machine consists of four parts: a machine head, a machine base, a transmission, and accessories. As an important part of the sewing machine, the sewing machine head will generate many burrs on the outside during production and processing. Therefore, it is necessary to use a grinding device to roughly grind the burrs on the surface of the sewing machine head, so as to reduce the workload of manually finely grinding the sewing machine head later.

[0003] However, currently during the processing and grinding of the sewing machine head, generally only one side is ground each time. Before grinding the other side of the sewing machine head, it is necessary to disassemble the sewing machine head from the fixing mechanism, adjust the position appropriately and then fix it again, resulting in the need to frequently rotate the sewing machine head to adjust the grinding surface. The operation is rather cumbersome and the work efficiency is reduced. Summary of the Invention

[0014] A method for grinding and leveling a sewing machine head surface The specific usage steps are as follows: S1. Fix the machine head. Place the sewing machine head to be ground and leveled in the right several third extension plates for preliminary fixing of the machine head. Then start the third cylinder. The output shaft of the third cylinder pushes one of the reinforcement plates towards the machine head. Through the second extension plate and the third extension plate contacting the surface of the machine head, the two reinforcement plates are closely attached to the surface of the machine head to fix the machine head, firmly fixing the machine head on the bottom plate. Then start the sixth motor in the moving assembly. The sixth motor drives the ball screw to rotate, causing the slider to move in the chute, thereby driving the bottom plate and the machine head placed thereon to adjust the horizontal position, moving the machine head to a suitable processing position. S2. Adjust the angle of the grinding disc. Start Motor 3 in the connecting component. Motor 3 drives Gear 1 to rotate. Gear 1 meshes with the semi-toothed ring on the outer wall of the spherical block. Thus, under the limitation of the reinforcing block, the spherical block is driven to rotate. Then, through the connecting column, Machine Case 1 and Adjustment Case 1 are driven, so that the grinding disc can be finely adjusted at multiple angles on the horizontal plane. And start Motor 2 to drive the spherical block to rotate 90° through Cylinder 1. At this time, starting Motor 3 can drive the grinding disc to be finely adjusted at multiple angles on the vertical plane. Meanwhile, start Motor 4. Motor 4 drives the extension column to rotate. The rotation of the extension column drives the grinding disc to adjust the angle around the arc surface of Adjustment Case 2, so that the angle of the grinding disc adapts to the surface to be ground flat of the machine head. S3. Grind the machine head. After completing the position and angle adjustment of the grinding disc, start Motor 1 in Machine Case 1. Motor 1 drives Adjustment Case 1 to rotate. Adjustment Case 1 then drives the grinding disc to rotate at a high speed to grind and flatten the surface of the sewing machine head. And start Motor 5. Through the setting of the rotating shaft and the two rotating plates, the machine head can be driven to rotate, so that multiple surfaces of the machine head can be processed and ground.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: 1. By setting a unique connecting component and an adjusting component, the present invention can realize the flexible adjustment of the grinding disc in multiple dimensions, can adapt to the surfaces of sewing machine heads with different shapes and positions, and there is no need to frequently disassemble and refix the machine head, which greatly improves the work efficiency. In the actual production process, for an ordinary sewing machine head, the traditional grinding method may require multiple disassembly and refix operations, and each operation is very time-consuming. While using this device, through the coordinated action of the connecting component and the adjusting component, only by operating the relevant motors and cylinders on the control panel, the adjustment of the grinding surface can be completed within 1 minute, and the overall processing time can be greatly shortened, which greatly improves the production efficiency. Also, through the rotating component and the moving component in the reinforcing unit, the position and angle of the machine head can be conveniently adjusted, so that the machine head can be ground in all directions, avoiding the limitations of the traditional grinding method. By driving the rotating shaft by Motor 5 of the rotating component, the machine head can be driven to rotate 360°, ensuring that all surfaces of the machine head can be covered by the grinding disc without missing any part. During the grinding process, with the multi-dimensional adjustment of the grinding disc, the grinding accuracy of the machine head surface can be improved, making the surface of the ground machine head smoother and flatter, providing a better surface quality basis for subsequent processing or use. For sewing machine heads with high-precision requirements, such as high-speed sewing machine heads, the surface roughness can be greatly reduced, ensuring the service performance and service life of the machine head.

[0016] 2. Through the settings of the bin door assembly and the control panel, the present invention facilitates the operator to monitor the processing process in real time and adjust parameters, ensuring the quality and accuracy of the grinding process, improving the convenience and controllability of the operation. The operator can observe the wear condition of the grinding disc through the inspection port. When it is found that the grinding disc is severely worn, the operator can timely adjust the rotation speed of the first motor or pause the processing to avoid affecting the grinding effect due to excessive wear of the grinding disc. At the same time, through the precise control of the telescopic amount of the cylinder by the control panel, the distance between the grinding disc and the surface of the machine head can be adjusted more accurately, avoiding the problems of over-grinding or under-grinding, and ensuring the stability of the processing quality. In addition, according to different materials of the machine head (such as aluminum alloy machine head and stainless steel machine head), the grinding parameters can be quickly adjusted on the control panel, improving the adaptability of the device to different materials and the flexibility of processing.

[0019] Please refer to Figures 1 - 7 , the present invention provides a technical solution: a grinding device for grinding the face of a sewing machine head, including a machine tool 1, one end of the machine tool 1 is provided with a door assembly 10 for inspecting the operation of the processing equipment inside the machine tool 1; a grinding unit 2, the grinding unit 2 is arranged inside the machine tool 1, the grinding unit 2 includes a grinding disc 20, a first adjustment box 21, a first chassis 22, a connection assembly 23, a first cylinder 24, a second adjustment box 25 and a second cylinder 26. A second cylinder 26 is installed on the top of the machine tool 1, the lower end of the second cylinder 26 is fixedly connected with the second adjustment box 25, a limiting block 27 is fixedly connected to the inner wall of one side of the machine tool 1, one end of the second adjustment box 25 is slidably connected with the limiting block 27, and the other end of the second adjustment box 25 is rotatably connected with a first cylinder 24.

A first motor 28 is installed inside the first chassis 22, the output shaft of the first motor 28 is fixedly connected with a first adjustment box 21, and the first adjustment box 21 is connected with a grinding disc 20 through an adjustment assembly 29; and a reinforcement unit 3, the reinforcement unit 3 is arranged under the machine tool 1 for installing and fixing the machine head 4.

[0020] The connecting component 23 includes an arc-shaped block one 230, a spherical block 231, an arc-shaped block two 232, a connecting column 233 and a driving mechanism 234. One end of the first cylinder 24 is fixedly connected to the arc-shaped block one 230.

The end of the spherical block 231 away from the arc-shaped block one 230 is fixedly connected to the arc-shaped block two 232. The end of the arc-shaped block two 232 away from the spherical block 231 is fixedly connected to the connecting column 233. One end of the connecting column 233 is fixedly connected to the first chassis 22. Start the third motor 2340 in the connecting component 23 to drive the first gear 2341 to rotate. Since the first gear 2341 meshes with the semi-tooth ring 2342 on the outer wall of the spherical block 231, the spherical block 231 rotates, and then drives the first chassis 22 and the first adjusting box 21 through the connecting column 233, realizing multi-angle fine adjustment of the grinding disc 20 on the horizontal plane. By precisely controlling the rotation angle of the first gear 2341 by the third motor 2340, flexible adjustment of the grinding disc 20 in the horizontal direction can be achieved, meeting the surface grinding requirements of the nose 4 with different shapes and angles.

[0021] Four equally spaced reinforcing blocks 235 are sleeved on the surface of the spherical block 231. One end of the reinforcing block 235 is fixedly connected to the arc-shaped block one 230. A second motor 250 is installed on the inner wall of the second adjusting box 25. One end of the second cylinder 26 is rotatably arranged in the second adjusting box 25. One end of the second cylinder 26 is integrally formed with an extension plate one 260. The middle of the extension plate one 260 is fixedly connected to the output shaft of the second motor 250.

At this time, start the third motor 2340 again to drive the grinding disc 20 to perform multi-angle fine adjustment on the vertical plane. This unique linkage mechanism realizes multi-angle adjustment of the grinding disc 20 in three-dimensional space through the coordinated work of the second motor 250 and the third motor 2340, which can avoid the problem of uneven grinding caused by the fixed angle of the grinding disc 20 and improve the uniformity and comprehensiveness of grinding.

One end of the first fixing block 292 penetrates through the second arc-shaped groove 293, and the end of the first fixing block 292 away from the extension column 291 is welded to the grinding disc 20. When the fourth motor 290 is started, it drives the extension column 291 to rotate. The rotation of the extension column 291 drives the grinding disc 20 to adjust the angle around the arc surface of the second adjustment box 25, so that the angle of the grinding disc 20 adapts to the surface to be ground of the machine head 4, ensuring that it can accurately contact each part of the machine head 4 to be ground. The rotation of the fourth motor 290 driving the extension column 291 can realize the adjustment of the grinding disc 20 within the range of ±45° around the arc surface, further refining the angle adjustment of the grinding disc 20, enabling the grinding disc 20 to better fit the surface of the machine head 4.

[0028] A method for a grinding and leveling device for the face washing of a sewing machine head The specific usage steps are as follows: S1. Fix the machine head 4. Place the sewing machine head 4 to be ground and leveled in several extension plates three 34 on the right side for initial fixation of the machine head 4. Then start the cylinder three 35. The output shaft of the cylinder three 35 pushes one of the reinforcement plates 32 towards the machine head 4. Through the extension plate two 33 and the extension plate three 34 in contact with the surface of the machine head 4, the two reinforcement plates 32 are closely attached to the surface of the machine head 4 to fix the machine head 4, firmly fixing the machine head 4 on the bottom plate 31. Then start the motor six 301 in the moving assembly 30. The motor six 301 drives the ball screw 302 to rotate, causing the slider 305 to move in the chute 304, thereby driving the bottom plate 31 and the machine head 4 placed thereon to adjust the horizontal position, moving the machine head 4 to a suitable processing position to ensure that the machine head 4 can be within the effective working range of the grinding disc 20 during the grinding and leveling process; S2. Adjust the angle of the grinding disc 20. Start the third motor 2340 in the connecting component 23. The third motor 2340 drives the first gear 2341 to rotate. The first gear 2341 meshes with the semi-toothed ring 2342 on the outer wall of the spherical block 231. Thus, driven by the limit of the reinforcing block 235, the spherical block 231 rotates. Then, through the connecting column 233, the first chassis 22 and the first adjusting box 21 are driven, so that the grinding disc 20 makes multi-angle fine adjustments on the horizontal plane. And start the second motor 250 to drive the spherical block 231 to rotate 90° through the first air cylinder 24.
