Description

Technical Field

[0001] This utility model relates to the field of knitting processing technology, and in particular to a limiting tool for knitting needle processing. Background Technology

[0002] In the knitting industry, knitting needles, as the core components of knitting machinery, directly determine the quality and production efficiency of knitted products through their machining precision. Knitting needle machining involves multiple processes such as grinding and polishing, requiring extremely high positioning accuracy. Currently, the main problems with existing limit fixtures in knitting needle machining are as follows: The adjustment methods are outdated: Most methods rely on manual rotation of the lead screw to adjust the clamping distance, which is cumbersome and difficult to control, resulting in low adjustment efficiency, insufficient clamping accuracy, and a tendency for needle deformation due to unstable clamping. Furthermore, the clamping components are mostly fixed structures, making it impossible to quickly change them for different needle specifications. Adapting to various needle sizes requires changing the entire tooling set, increasing production costs and reducing processing efficiency. Therefore, we propose a limiting tooling for needle processing. Utility Model Content

[0015] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0016] like Figure 1-3As shown, this utility model is a limiting fixture for knitting needle processing, including a base 1. A limiting groove 2 is formed on the side of the base 1. Two sets of movable seats 3 are movably engaged in the limiting groove 2. An mounting seat 4 is installed at the end of the movable seat 3. A threaded hole 5 and a guide hole 6 are formed parallel to each other on the side of the movable seat 3. A bidirectional lead screw 7 is screwed into the threaded hole 5. One end of the bidirectional lead screw 7 is connected to a motor 9. An mounting groove 11 is formed on the side of the mounting seat 4. A positioning plate 12 is provided on the side of the mounting seat 4. A clamping plate 13 is installed on one side of the positioning plate 12. A connecting block 14 is provided on the other side of the positioning plate 12. The connecting block 14 is engaged in the mounting groove 11 and fixed by bolts 15. The limiting groove 2 guides and limits the moving seat 3, ensuring its stable linear movement. The bidirectional lead screw 7, in conjunction with the threaded hole 5, enables the two sets of moving seats 3 to move synchronously in opposite directions under the drive of the motor 9, thereby driving the clamping plate 13 to clamp or release the knitting needles. The design of the connecting block 14 and the mounting groove 11 allows for the replacement of different sizes of positioning plates 12 and clamping plates 13 according to the knitting needle specifications, and the connection strength is ensured by fixing with bolts 15. This achieves automated clamping adjustment and rapid changeover, improving processing efficiency and versatility.

[0017] By cooperating with the motor 9 and the bidirectional lead screw 7, two sets of moving seats 3 are driven to move synchronously in opposite directions along the limiting groove 2, realizing the automatic adjustment of the clamping distance and solving the problems of low efficiency and insufficient precision of traditional manual adjustment. By cooperating with the guide rod 8 and the guide hole 6, the movement trajectory of the moving seat 3 is restricted, preventing it from deviating or jamming when driven by the bidirectional lead screw 7, thus solving the stability problem during movement. By cooperating with the anti-slip pad on the clamping plate 13, the contact area with the knitting needle is increased and the friction is increased, solving the problem of easy slippage in traditional clamping that leads to processing errors. By the snap-fit ​​structure between the connecting block 14 and the mounting groove 11 and the bolt 15, the positioning plate 12 and the clamping plate 13 can be quickly disassembled and replaced, solving the problem of poor versatility of traditional tooling.

[0018] In the above scheme, a support column is provided at the bottom of the base 1. The support column is used to raise the height of the base 1, avoiding vibration transmission caused by direct contact between the base 1 and the worktable surface during processing, and at the same time reserving space for operation below. This enhances the overall stability of the tooling and reduces the impact of external vibration on processing accuracy.

[0019] In the above scheme, the movable seat 3 is coated with a wear-resistant layer on the side near the base 1. The wear-resistant layer is made of a high-strength wear-resistant material (such as a ceramic coating), which can reduce the wear caused by long-term relative sliding between the movable seat 3 and the inner wall of the limiting groove 2, and extend the service life of the equipment. It also reduces component wear and improves the durability of the tooling.

[0020] In the above scheme, a guide rod 8 is arranged parallel to the side of the bidirectional lead screw 7. The guide rod 8 is movably inserted into the guide hole 6. One end of the bidirectional lead screw 7 is movably connected to the base 1 through a bearing seat, and the end of the guide rod 8 is fixed on the base 1. The sliding fit between the guide rod 8 and the guide hole 6 can counteract the radial force generated when the bidirectional lead screw 7 rotates, preventing the moving seat 3 from tilting or jamming; the bearing seat ensures stable rotation of the bidirectional lead screw 7 and reduces axial movement. This improves the motion stability of the moving seat 3 and ensures the positioning accuracy of the clamping plate 13.

[0021] In the above scheme, a control panel 10 is installed on the base 1. The control panel 10 is electrically connected to the motor 9 and can control the start, stop, speed, and direction of the motor 9 through a preset program or manual operation, thereby achieving precise adjustment of the clamping distance. This simplifies the operation process and improves adjustment efficiency and accuracy.

[0022] In the above solution, the clamping plate 13 has an arc-shaped groove on its side, and an anti-slip pad is provided inside the arc-shaped groove. The curvature of the arc-shaped groove is adapted to the outer contour of the knitting needle, which can increase the contact area; the anti-slip pad is made of rubber, which increases friction to prevent the knitting needle from sliding or rotating during processing. This improves clamping stability and avoids accuracy errors caused by knitting needle deviation during processing.

[0023] In the above scheme, the connecting block 14 and the mounting groove 11 are at the same height, and both the connecting block 14 and the mounting base 4 have connecting holes on their upper sides. The consistent height of the connecting block 14 and the mounting groove 11 ensures the levelness of the positioning plate 12 after installation, preventing the clamping plate 13 from tilting. The connecting holes are for bolts 15 to pass through and tighten, ensuring a tight fit between the connecting block 14 and the mounting groove 11 without loosening. This improves the installation accuracy and connection reliability of the positioning plate 12, ensuring clamping stability.

[0024] Working principle: In the initial state, the two sets of moving seats 3 are located at both ends of the limiting groove 2, and the clamping plates 13 maintain the maximum distance between them to facilitate the placement of the knitting needles to be processed. A suitable clamping plate 13 is selected according to the knitting needle specifications, and the connecting block 14 of the positioning plate 12 is inserted into the mounting groove 11 of the mounting base 4. The clamping components are then assembled by fastening the bolts 15 through the connecting holes. After starting the control panel 10 and setting the clamping parameters, the motor 9 drives the bidirectional lead screw 7 to rotate. Because the threads at both ends of the bidirectional lead screw 7 are in opposite directions, the two sets of moving seats 3 are positioned at the threads... Under the action of hole 5, the needle moves synchronously towards the limiting groove 2. The guide rod 8 cooperates with the guide hole 6 to ensure a stable movement trajectory. The moving seat 3 drives the mounting seat 4 and the clamping plate 13 to gradually approach the knitting needle until the arc groove of the clamping plate 13 is in contact with the surface of the knitting needle. The anti-slip pad firmly clamps the knitting needle through friction. At this time, the control panel 10 controls the motor 9 to stop working. After processing, the control panel 10 controls the motor 9 to reverse, the bidirectional lead screw 7 drives the moving seat 3 to move in the opposite direction, the clamping plate 13 releases the knitting needle, and the processed knitting needle can be removed for the next operation. Through the above process, the knitting needle is automatically and precisely clamped, and it also has the function of quickly changing the clamping parts to adapt to different specifications of knitting needles, effectively improving processing efficiency and accuracy.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
