Description

Technical Field

[0001] This utility model relates to the field of electrode post processing technology, specifically to an elastic clamping and positioning device for electrode post processing. Background Technology

[0002] In the processing of ordinary electrodes, the electrode blank must first be clamped on the table of the machining center. The blank must be calibrated, centered, and tool set before machining can be carried out. The horizontal reference edge, vertical reference edge, and electrode reference surface need to be machined.

[0003] According to the patent titled "A Fixture for Processing Cylindrical Electrodes" (Patent Publication No.: CN213411205U, Patent Publication Date: 2021-06-11), the fixture includes a base, an L-shaped positioning block mounted on the base, and a top block mounted on the base at an angle corresponding to the positioning block. The top block is horizontally slidably mounted on the base, and a tapered end that engages with the angle is located on the side of the top block facing the positioning block. An adjustment mechanism for driving the top block to move is provided on the base. Limiting mechanisms are provided at the horizontal and vertical ends of the positioning block corresponding to the position of the top block. Each limiting mechanism includes a slider horizontally slidable on the positioning block facing the top block and a telescopic block mounted on the slider. An assembly groove for mounting the telescopic block is provided on the side of the slider facing the top block. This design is simple in structure, easy to operate and use, and can not only achieve stable clamping and fixing of cylindrical electrodes but also ensure that the cylindrical electrodes remain vertical during the fixing process, which is beneficial for improving the processing accuracy of cylindrical electrodes.

[0004] Based on the aforementioned existing technology, current elastic clamping and positioning devices for electrode post processing still have the following problems: traditional single-station devices can only clamp and process one electrode post at a time. After completing the processing of one workpiece, it is necessary to stop the machine, unload the workpiece, clamp a new workpiece, and reposition it before starting the next round of processing, resulting in low processing efficiency. Therefore, this utility model provides an elastic clamping and positioning device for electrode post processing. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an elastic clamping and positioning device for electrode post machining. This solves the following problems associated with existing elastic clamping and positioning devices for electrode post machining: traditional single-station devices can only clamp and machine one electrode post at a time. After machining one workpiece, the machine needs to be stopped, unloaded, a new workpiece clamped, and repositioned before the next round of machining can begin, resulting in low machining efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an elastic clamping and positioning device for electrode post processing, comprising a worktable, wherein a clamping and positioning mechanism is provided on the top of the worktable for multi-station clamping and fixing, the clamping and positioning mechanism comprising:

[0007] A multi-station clamping unit is disposed above a workbench, including a housing fixedly installed on the top of the workbench.

[0008] The rotating unit, located inside the housing, is used to rotate the clamping assembly, enabling the machining of different surfaces of the electrode post.

[0009] Preferably, the clamping assembly includes a rotating seat rotatably mounted inside a circular groove on the top of the housing. The rotating seat has a pair of symmetrically arranged cross grooves inside, and a cross block is slidably mounted inside the cross grooves.

A connecting shaft is rotatably installed above the support end of the connecting frame, and a linkage block is fixedly installed at the top of the connecting shaft. A set of sliding grooves are symmetrically opened inside the linkage block, and the sliding column slides inside the sliding groove. The sliding column slides inside the sliding groove by moving the linkage block up and down, thereby driving the cross block and the clamping block to move.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] Please see Figures 1-4 This utility model provides a technical solution:

[0024] An elastic clamping and positioning device for electrode post processing includes a worktable 1. A clamping and positioning mechanism 2 is provided on the top of the worktable 1 for multi-station clamping and fixing. The clamping and positioning mechanism 2 includes:

[0025] A multi-station clamping unit 21 is disposed above the workbench 1. It includes a housing 211 fixedly installed on the top of the workbench 1, a cylinder 212 fixedly installed on the bottom of the workbench 1, and a connecting frame 213 fixedly installed through the workbench 1 and the housing 211. The connecting frame 213 is installed inside the housing 211. Several clamping components 3 are arranged in a circular array on the top of the housing 211, and clamping components 3 are respectively arranged above the support ends of the connecting frame 213. Multi-station clamping and fixing are achieved through several clamping components 3.

[0026] The rotating unit 22 is located inside the housing 211 and is used to rotate the clamping assembly 3 to process different surfaces of the electrode post.

[0027] The cylinder 212 is model DSNU-20-50-PPV-A, which is electrically connected to an external power source and is operated by a human-controlled control panel.

[0028] In this embodiment, the clamping assembly 3 includes a rotating seat 31 rotatably mounted inside a circular groove on the top of the housing 211. A pair of cross grooves 32 are symmetrically opened inside the rotating seat 31, and a cross block 33 is slidably mounted inside the cross groove 32. A clamping block 34 is fixedly mounted on the top of the cross block 33. The clamping block 34 clamps and fixes the electrode post by sliding the cross block 33 inside the cross groove 32.

[0029] The rotating seat 31 has a cross groove 32 inside, and the cross block 33 slides in the groove to drive the clamping block 34 to clamp. The clamping block 34 adapts to the change of the outer diameter of the electrode post to avoid over-clamping deformation; at the same time, it ensures that the two clamping blocks are synchronously and accurately aligned.

[0030] In this embodiment, a linkage rod 37 is fixedly installed at the bottom of the cross block 33, and sliding columns 38 are fixedly installed on both sides of the linkage rod 37. A connecting shaft 36 is rotatably installed above the support end of the connecting frame 213, and a linkage block 39 is fixedly installed at the top of the connecting shaft 36. A set of sliding grooves 310 are symmetrically opened inside the linkage block 39, and the sliding column 38 slides inside the sliding groove 310. The sliding column 38 slides inside the sliding groove 310 by moving the linkage block 39 up and down, thereby driving the cross block 33 and the clamping block 34 to move.

[0031] The linkage block 39 is provided with an inclined slide groove 310, in which the sliding column 38 slides to drive the linkage rod 37 to move horizontally, synchronously controlling the multi-station clamping action to ensure that all electrode columns are subjected to uniform force.

[0032] In this embodiment, a rubber pad 35 is fixedly installed on the V-shaped surface of the clamping block 34 to prevent the clamping block 34 from causing wear on the surface of the electrode post.

[0033] The clamping block 34V surface is attached with a rubber pad 35. The rubber pad 35 provides cushioning and eliminates hard metal contact, preventing scratches and meeting the zero-damage requirement of precision electrode posts.

[0034] In this embodiment, the rotating unit 22 includes a gear ring 221 fixedly mounted on the surface of the rotating seat 31, a rotating shaft 222 is rotatably mounted in the middle of the top of the inner cavity of the worktable 1, and a gear disk 223 is fixedly mounted on the surface of the rotating shaft 222, and the gear disk 223 is meshed with the gear ring 221.

[0035] The gear ring 221 is fixed to the rotating seat 31 and meshes with the gear disk 223 to drive rotation. The synchronous rotation of multiple stations ensures the consistency of the angle of all electrode post machining surfaces and avoids positioning errors caused by adjusting them one by one.

[0036] In this embodiment, a worm gear 224 is fixedly installed at the bottom end of the rotating shaft 222, a rotating column 225 is rotatably installed inside the housing 211, and a worm 226 is fixedly installed on the surface of the rotating column 225, and the worm 226 meshes with the worm gear 224. A handwheel 227 is fixedly installed at one end of the rotating column 225 through the housing 211.

[0037] The worm gear 226 and worm wheel 224 are driven by the handwheel 227, which in turn drives the gear disk 223 and gear ring 221 to rotate the clamping assembly 3 as a whole, thereby enabling multi-face machining to be completed by rotating the electrode post without disassembling the workpiece.

[0038] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0039] During operation, the electrode post is first placed vertically above the center of the rotating seat 31. The cylinder 212 moves the connecting frame 213 downward, which in turn moves the connecting shaft 36 downward. The connecting shaft 36 moves the linkage block 39 downward, causing the sliding column 38 to slide inside the sliding groove 310. This causes the two linkage rods 37 to move towards each other, which in turn moves the two cross blocks 33 towards each other. The two cross blocks 33 then move the two clamping blocks 34 to clamp and fix the motor post.

[0040] Then, when processing different surfaces of the electrode post, the operator manually cranks the handwheel 227 to rotate the rotating column 225, which in turn rotates the worm gear 226, which in turn rotates the worm wheel 224, which in turn rotates the gear disc 223, which in turn rotates the gear ring 221, which in turn rotates the clamping assembly 3, thus rotating the electrode post and processing different surfaces of the electrode post.
