Description

Technical Field

[0001] This utility model relates to the field of electrode processing technology, and in particular to an adjustable clamping head for electrode processing. Background Technology

[0002] In modern industrial production, electrode processing is a key link in many fields of electronics and mechanical manufacturing. The precision and efficiency of electrode processing directly affect the quality and performance of the final product. During the electrode processing, the clamping device for the electrode plays a vital role.

[0003] Adjustable chucks for electrode processing consist of a support base and a clamping screw to grip the electrode. Currently, some adjustable chucks require operators to tighten multiple bolts sequentially to fix the electrode during adjustment, which is cumbersome and increases the burden on operators, failing to meet the user's need for efficiency and convenience. Existing solutions use chucks with tapered holes or wedge structures. When the electrode is inserted into the chuck, it automatically moves along the tapered hole or wedge structure to the center position and is clamped by the structure's compression. However, during long-term use, the tapered hole or wedge structure of the chuck will wear due to frequent contact and friction with the electrode. As wear intensifies, the surface roughness of the tapered hole or wedge structure increases, and its shape changes, reducing the fit accuracy between the electrode and the chuck. This weakens the chuck's compression effect on the electrode, resulting in insufficient clamping force. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an adjustable chuck for electrode processing, aiming to improve the problem that the tapered hole of the chuck in the prior art will wear down due to frequent contact and friction with the electrode during long-term use, resulting in a weakening of the chuck's squeezing effect on the electrode and insufficient clamping force.

The upper and lower ends of the outer wall of the moving tooth are provided with two grippers. The front and rear sides of the outer walls of the two grippers are provided with three sliding grooves. The outer walls of the two grippers are provided with multiple racks. The outer walls of the multiple racks are respectively engaged with the outer walls of the rotating tooth. The top of the fixed column is provided with multiple sliding grooves. The left and right sides of the inner walls of the multiple sliding grooves are fixedly connected with sliders.

A connecting block is fixedly connected to the top left side of each of the two docking blocks. A locking block is rotatably connected between adjacent parts of the two connecting blocks.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of an adjustable chuck for electrode processing, comprising a fixed post 1, which serves as the basic support component of the entire chuck. A rotary valve 3 is provided on the front side of the outer wall of the fixed post 1. A bidirectional threaded rod 4 is rotatably connected to the top of the inner wall of the rotary valve 3. The front end of the bidirectional threaded rod 4 penetrates the inner wall of the fixed post 1 and is fixedly connected to the rotary valve 3. When the rotary valve 3 rotates, the bidirectional threaded rod 4 rotates accordingly. Clamping jaws 5 are rotatably connected to the front and rear sides of the outer wall of the bidirectional threaded rod 4. The two clamping jaws 5 move relative to or in opposite directions along the axial direction of the bidirectional threaded rod 4. Sliding grooves 6 are provided on the left and right sides of the outer wall of the two clamping jaws 5, which guide and stabilize the clamping jaws 5 during movement. A rotating tooth 7 is fixedly connected to the middle of the outer wall of the bidirectional threaded rod 4. The upper and lower ends of the outer wall of the tooth 7 are provided with grippers 2 8. When the bidirectional threaded rod 4 drives the rotating tooth 7 to rotate, the rotational motion is transmitted to the grippers 2 8, so that the grippers 2 8 can move along the direction of meshing with the rotating tooth 7. The front and rear sides of the outer wall of the two grippers 2 8 are provided with sliding grooves 3 18. The outer wall of the two grippers 2 8 is provided with multiple racks 17. The outer walls of the multiple racks 17 are respectively meshed with the outer wall of the rotating tooth 7. The top of the fixed column 1 is provided with multiple sliding grooves 2 9. The sliders 10 can slide in the sliding grooves 2 9, which plays a good guiding role. The inner walls of the multiple sliding grooves 2 9 are fixedly connected to the left and right sides. The inner and outer walls of the multiple sliders 10 are respectively slidably connected to the inner walls of the sliding grooves 1 6 and 3 18. The top of the fixed column 1 is provided with a connecting mechanism 2. The connecting mechanism 2 is used to install the device.

[0032] Specifically, the fixed post 1 serves as the basic support component of the entire clamp, providing a stable installation platform for each component. The rotary valve 3 on the front side of the outer wall is rotatably connected to the bidirectional threaded rod 4. When the rotary valve 3 rotates, the bidirectional threaded rod 4 rotates accordingly. The gripper 5, rotatably connected to the front and rear sides of the outer wall of the bidirectional threaded rod 4, will move in opposite or opposite directions along its axial direction due to the bidirectional thread design of the bidirectional threaded rod 4. The sliding grooves 6 on the left and right sides of the outer wall of the gripper 5 are slidably connected to the sliders 10 fixed on the left and right sides of the inner wall of the sliding groove 9 at the top of the fixed post 1, achieving a guiding and stabilizing effect. The middle of the outer wall of the bidirectional threaded rod 4 is fixed. The rotating tooth 7 has two jaws 8 at the upper and lower ends of its outer wall. These jaws mesh with the rotating tooth 7 through multiple racks 17 on the outer wall. When the bidirectional threaded rod 4 drives the rotating tooth 7 to rotate, the rotational motion is transmitted to the jaws 8, causing them to move along the meshing direction. The sliding grooves 18 on the front and rear sides of the outer wall of the jaws 8 are also slidably connected to the slider 10. The rotation of the rotary valve 3 drives the jaw 5 to move through the bidirectional threaded rod 4, and at the same time drives the jaw 8 to move through the rotating tooth 7. The sliding grooves cooperate with the slider 10 to ensure the accuracy and stability of the jaw movement, and meet the reliable clamping requirements for electrodes of different sizes during electrode processing.

[0033] Reference Figure 1 , Figure 2 and Figure 5 The connecting mechanism 2 includes a connecting column 201. The bottom of the connecting column 201 is fixedly connected to the top of the fixed column 1. A docking groove 202 is provided in the middle of the top of the connecting column 201, so that the part docking with the docking groove 202 can be accurately embedded to achieve mechanical connection. A docking block 203 is provided on the front and rear sides of the inner wall of the docking groove 202. A connecting block 204 is fixedly connected to the top left side of the two docking blocks 203. The connecting block 204 mainly plays the role of connection and rotation support. A locking block 205 is rotatably connected between the adjacent two connecting blocks 204. A locking groove 206 is provided on the top of the two docking blocks 203. When the external docking part is inserted into the docking block 203, the locking block 205 is rotated to lock into the locking groove 206, thereby firmly locking the external part in the docking block 203.

[0034] Specifically, the bottom of the connecting column 201 is fixed to the top of the fixed column 1, serving as a bridge connecting the fixed column 1 and the upper component, ensuring the stability of the entire device structure and the effective transmission of force. The docking groove 202 in the middle of the top of the connecting column 201 allows the docking component to be accurately embedded, achieving a stable mechanical connection and ensuring the tightness and accuracy of the connection. The docking blocks 203 on the front and rear sides of the inner wall of the docking groove 202 further realize the connection. The connecting block 204 on the top left of the docking block 203 mainly functions as a connection and rotation support point, providing a basis for the rotation of the locking block 205. The locking blocks 205 rotatably connected between adjacent connecting blocks 204 have flexible rotation characteristics. The locking groove 206 on the top of the docking block 203 cooperates with the locking block 205. When the external docking component is inserted into the docking block 203, the operator can rotate the locking block 205 to accurately lock it into the locking groove 206, firmly locking the external component in the docking block 203, completing the connection, and ensuring that the external docking component will not loosen or fall off during the electrode processing, ensuring the smooth progress of the processing.

[0035] Reference Figure 1 , Figure 2 and Figure 4 The lower part of the inner wall of the fixed column 1 is provided with a mounting groove 11, and a lighting lamp 12 is fixedly connected to the inner wall of the mounting groove 11. The lighting lamp 12 provides sufficient lighting for the electrode processing area. The middle part of the outer wall of the fixed column 1 is provided with a mounting groove 13, and a reflective sticker 14 is provided on the inner wall of the mounting groove 13. The main function of the reflective sticker 14 is to enhance the light reflection effect of the working area. The inner wall of the docking block 203 has a connecting groove 15 on both the front and rear sides. The inner walls of the two connecting grooves 15 are fixedly connected to the bottom of the two docking blocks 203 respectively. The design of the connecting grooves 15 is to realize the stable connection of the docking block 203 with other components.

[0036] Specifically, after the inner wall of the mounting groove 11 is fixedly connected to the lighting lamp 12, the lighting lamp 12 can provide sufficient lighting for the electrode processing area, the reflective sticker 14 can enhance the light reflection effect of the working area, and the connecting groove 15 provides a specific space and method for connection, ensuring that the mating block 203 can withstand external force without loosening during the electrode processing, ensuring the reliability of the entire connection structure, thereby providing a strong guarantee for the accuracy of electrode processing.

[0037] Reference Figure 1 , Figure 2 and Figure 3The two docking blocks 203 have connecting grooves 16 starting from the top left side. The inner walls of the two connecting grooves 16 are fixedly connected to the bottom of the two connecting blocks 204, allowing the connecting blocks 204 to be installed and positioned. The two locking blocks 205 are equidistantly rotatably connected between the adjacent connecting blocks 204. The outer walls of the two locking blocks 205 are rounded to prevent the parts from shifting or shaking during processing. The outer walls of the connecting column 201 are rounded on the front and back sides, and the outer walls of the two docking blocks 203 are also rounded, which can effectively prevent sharp edges from causing accidental injury to surrounding personnel and improve the safety of equipment operation.

[0038] Specifically, the connecting block 204 can be precisely installed and positioned by relying on the docking block 203, and the force applied to the parts to be docked is evenly distributed. When the external part is inserted into the docking groove 202, the locking block 205 rotates to lock the part, preventing the part from shifting or shaking during processing. The smooth outer wall of the docking block 203 can effectively prevent sharp edges from causing accidental injury to people around.

[0039] Working principle: The fixed column 1 serves as the basic support component, providing stable support for the entire clamping head. When the electrode needs to be clamped, the rotary valve 3 on the front side of the outer wall of the fixed column 1 is rotated, and the bidirectional threaded rod 4 fixedly connected to it rotates accordingly. The bidirectional thread design of the bidirectional threaded rod 4 allows the jaws 5 on the front and rear sides of its outer wall to move in opposite or opposite directions along the axial direction. The sliding groove 6 on the outer wall of the jaw 5 cooperates with the slider 10 in the sliding groove 9 at the top of the fixed column 1, ensuring the guidance and stability of the jaw 5 during movement. At the same time, the bidirectional threaded rod 4 drives the rotating tooth 7 in the middle of the outer wall to rotate. The rotating tooth 7 meshes with the rack 17 on the outer wall of the jaw 8, transmitting the rotational motion to the jaw 8, causing the jaw 8 to move in the meshing direction. The sliding groove 18 on the front and rear sides of the outer wall of the jaw 8 also cooperates with the slider 10 to ensure stable movement, thereby completing the electrode clamping.

[0040] Furthermore, by fixing the bottom of the connecting column 201 to the top of the fixing column 1, the connecting fixing column 1 is connected to the connecting arm on the entire device. The docking groove 202 at the top center of the connecting column 201 allows the docking arm to be inserted, achieving a stable mechanical connection and ensuring a tight and accurate connection. The docking blocks 203 on the front and rear sides of the inner wall of the docking groove 202 further strengthen the connection. The connecting block 204 serves as a connection and rotation support point, providing a rotational basis for the locking block 205, allowing the locking block 205 to rotate. When the connecting arm on the external docking component is inserted into the docking block 203, the operator rotates the locking block 205 to lock it into the locking groove 206 at the top of the docking block 203, firmly locking the external connecting arm in the docking block 203, preventing the external connecting arm from falling off during electrode processing, and ensuring smooth processing.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
