Description

Technical Field

[0001] The utility model relates to a special grinding tool, in particular to a special grinding tool suitable for grinding and removing welding slag around the friction welding point of the anode plate stud of a foil machine, belonging to the technical field of foil machine manufacturing. Background Art

[0002] The working principle of the foil machine is to use electrochemical reaction to deposit metal or non-metal materials on the substrate to form a thin film. It is the main equipment used in the production of foil products such as copper foil and aluminum foil. The anode plate of the foil machine is an important part of the foil machine. The anode plate of the foil machine can be divided into inlaid type and back-pull type according to the shape. The back-pull anode plate is a vertically fixed anode plate with multiple studs for pulling the anode plate. The fixing method of the stud and the anode plate is usually a friction welding process. After the friction welding is completed, a lot of welding slag is usually generated at the welding position at the bottom of the stud. The welding slag needs to be removed by grinding. The traditional method of grinding with a polishing machine has the problems of uneven grinding, poor grinding effect and low grinding efficiency. When using a sleeve-type grinding tool that is mounted on the stud for grinding, the welding slag around the welding position at the bottom of the stud can be removed by controlling the rotation of the sleeve-type grinding tool. However, since the stud is mounted inside the tool, the stud is easily damaged during the high-speed rotation of the sleeve-type grinding tool. Summary of the invention

[0003] In view of the problems existing in the above-mentioned prior art, the utility model provides a special grinding tool for the periphery of the friction welding point of the anode plate stud, which can avoid damaging the stud during the grinding process while achieving efficient grinding, and is particularly suitable for the grinding and removal process of welding slag around the friction welding point of the anode plate stud of a foil production machine.

[0019] The utility model is further described below in conjunction with the accompanying drawings.

[0020] like Figure 1 As shown, the special grinding tool for the periphery of the friction welding point of the anode plate stud comprises a sleeve portion 1, an assembly rod 2 and a tool assembly 3.

[0021] A blind hole cavity 11 is coaxially provided inside the sleeve portion 1, and the opening position of the blind hole cavity 11 is located correspondingly at the bottom end of the sleeve portion 1. The inner diameter of the blind hole cavity 11 is larger than the outer diameter of the stud 4. A bearing 12 is coaxially fixed inside the blind hole cavity 11. The bearing 12 is preferably a deep groove ball bearing. The inner diameter of the inner ring of the bearing 12 is larger than the outer diameter of the stud 4, and the inner diameter of the inner ring of the bearing 12 is smaller than the inner diameter of the blind hole cavity 11. The bearings 12 can be stacked in multiple layers.

[0022] The assembly rod 2 is coaxially fixedly arranged on the top end of the sleeve portion 1 and is used for connecting to the main shaft of the polishing machine.

[0023] The tool assembly 3 includes a tool holder 31, which is installed at the bottom end of the sleeve portion 1 and is symmetrically arranged in multiple pieces relative to the center of the sleeve portion 1. A blade 32 is installed on the tool holder 31, and the cutting edge of the blade 32 extends downward and is at least flush with the bottom end surface of the tool holder 31. The cutting edge of the blade 32 may also slightly protrude from the bottom end surface of the tool holder 31.

[0024] When the welding slag around the friction welding point of the anode plate stud 4 of the foil machine is polished by using the special polishing tool around the friction welding point of the anode plate stud, the special polishing tool around the friction welding point of the anode plate stud can be coaxially fixedly installed on the main shaft of the polishing machine through the assembly rod 2, and then the polishing machine is controlled to make the blind hole cavity 11 align with the top of the stud 4 and insert the stud 4, such as Figure 2 As shown, the polishing machine is started and controlled to move the special grinding tool downward along the axial direction of the stud 4. At this time, the blade 32 rotating at high speed with the tool holder 31 can scrape and grind the welding slag at the bottom of the stud 4 until the bottom end surface of the tool holder 31 is close to the anode plate, and the grinding is completed. During the grinding process, the stud 4 is in a state of being inserted into the bearing 12. Therefore, even if the stud 4 contacts the inner ring of the bearing 12, the outer ring of the bearing 12 can rotate relative to the inner ring, thereby avoiding the stud 4 from being roughened due to hard friction.

[0025] In order to further avoid damaging the stud 4 during the grinding process, as a further improvement scheme of the utility model, Figure 1 , Figure 2 As shown, a damping sleeve 13 is coaxially fixed on the inner ring of the bearing 12, and the inner diameter of the damping sleeve 13 is larger than the outer diameter of the stud 4. The damping sleeve 13 can be made of rubber or resin material. The setting of the damping sleeve 13 can further prevent the stud 4 from being roughened due to hard friction.

[0026] In order to facilitate the installation of the bearing 12 in the blind hole cavity 11 and to facilitate the replacement of the bearing 12 for the studs 4 with different outer diameters, as a further improvement scheme of the utility model, Figure 1 , Figure 2 As shown, the tool assembly 3 also includes a tool body 33 of a step guide sleeve structure, the tool body 33 is coaxially fixedly mounted on the bottom end of the sleeve portion 1, and the tool holder 31 is fixedly mounted on the bottom end of the tool body 33, that is, the tool holder 31 is mounted on the bottom end of the sleeve portion 1 through the tool body 33, and the inner hole of the guide sleeve of the tool body 33 forms an extension of the blind hole cavity 11 in the downward direction, and the inner diameter size of the inner hole of the guide sleeve of the tool body 33 is not less than the inner diameter size of the inner ring of the bearing 12. The bearing 12 in the blind hole cavity 11 can be installed or replaced by removing the tool body 33.

[0027] In order to further facilitate the installation or replacement of the bearing 12, as a further improvement of the utility model, Figure 1 , Figure 2 As shown, the bearing 12 is coaxially fixedly arranged in the guide sleeve of the tool body 33.

[0028] To facilitate the adjustment of the scraping range of the blade 32, as a further improvement scheme of the utility model, the tool holder 31 is installed at the bottom end of the sleeve portion 1 through a translational positioning and locking mechanism arranged along the radial direction of the sleeve portion 1. The translational structure of the translational positioning and locking mechanism can adopt a T-slot and T-protrusion method that are arranged in conjunction with each other, or a dovetail groove and dovetail protrusion method that are arranged in conjunction with each other. The locking structure of the translational positioning and locking mechanism can adopt a locking screw locking method, or a wedge block locking method. By adjusting the translational positioning and locking mechanism, the tool holder 31 can be moved and positioned along the radial direction of the sleeve portion 1, thereby changing the radial position of the blade 32 relative to the sleeve portion 1, thereby adjusting the scraping range of the blade 32.
