Abstract
Description
Technical Field
[0001] The utility model relates to the field of electrode cap grinding tools, in particular to an electrode cap grinding tool with a restraining function. Background Art
[0002] Resistance spot welding is an efficient and low-cost welding method that has been widely used in modern industrial production. The surface quality of the electrode cap directly affects the quality of the final workpiece, so in the process of resistance spot welding, it is necessary to grind the shape of the electrode cap after welding a certain number of welds, cut off the oxidized part of the electrode cap, remove the surface roughness and unevenness, and then ensure the appearance of the weld, thereby improving the surface quality and precision of the workpiece.
[0003] Currently, most of the electrode cap grinding tools on the market are ground by rotary cutting. However, during the grinding process of existing tools, the electrode cap is prone to deviation, resulting in large cutting vibration, which affects the quality of the cutting surface of the electrode cap and increases the roughness of the cutting surface. Utility Model Content
[0004] In order to overcome the deficiencies of the prior art, the utility model provides an electrode cap grinding tool with a restraining function, which solves the problem that the electrode cap is prone to deviation during the grinding process, which easily causes an uneven cutting surface.
[0005] The utility model adopts the following technical solutions:
[0006] An electrode cap grinding tool with a restraining function comprises a tool holder, a mounting hole passing through the tool holder, a tool core arranged in the mounting hole, a plurality of restraining members evenly distributed along the circumference of the mounting hole on the inner wall of the mounting hole, and the restraining members are detachably connected to the tool holder.
[0007] With the above technical solution, during the grinding process, the restraint rotates with the tool holder. If the electrode cap deviates, the electrode cap touches the rotating restraint. Under the action of the restraint, the deviated electrode cap is corrected, thereby reducing cutting vibration and improving the grinding quality. In addition, when the size of the electrode cap to be ground changes, the restraint can be removed from the tool holder and replaced, so that the size of the restraint always matches the size of the electrode cap to be ground.
[0008] Furthermore, the inner wall of the mounting hole is evenly provided with a plurality of mounting grooves along the circumference of the mounting hole, the restraining members are arranged in the mounting grooves one by one, and the restraining members extend into the mounting hole.
[0009] By adopting the above technical solution, the mounting groove limits the restraining member therein, so as to prevent the restraining member from being knocked away by the deviated electrode cap during the grinding process, thereby improving the stability of the grinding.
[0010] Furthermore, the cutter core is composed of a plurality of cutting structures, which are arranged in a circular matrix, and the cutting structure includes a cutting back face, a positioning face, a cutting edge and a chip removal opening.
[0011] By adopting the above technical scheme, the cutting back surface provides stable support for the tool core, the positioning surface ensures that the tool has the correct position and direction during the processing, the cutting edge directly performs cutting processing, and the chip removal port discharges the waste chips generated during the cutting process, and they work together to achieve efficient and accurate electrode cap grinding and cutting processing.
[0012] Furthermore, the restraining member comprises an arc structure and a threaded hole which are symmetrical in the upper and lower parts, and the tool holder has a plurality of positioning holes which are evenly distributed along the circumference of the mounting hole and are matched with the threaded hole, and the threaded hole and the positioning hole are connected by screws.
[0013] By adopting the above technical solution, when the size of the electrode cap to be repaired changes, the screw connected between the threaded hole and the positioning hole can be removed, so that the constraint on the tool holder can be replaced, so that the size of the constraint always matches the size of the electrode cap to be repaired. And the connection method between the constraint and the tool holder is also relatively simple.
[0014] Furthermore, a plurality of penetrating chip removal holes are evenly distributed along the circumference of the tool holder, and the chip removal holes and the restraining members are staggered in position.
[0015] By adopting the above technical solution, the plurality of chip removal holes can meet the chip removal requirements of a large amount of waste chips generated during rotary cutting, effectively increase the chip removal amount, and prevent chip blockage and tool edge breakage. In addition, the chip removal holes and the restraining parts are staggered to avoid the restraining parts hindering chip removal.
[0016] Furthermore, the axes of the knife core and the knife seat are located on the same straight line.
[0017] By adopting the above technical solution, the rotational motion of the cutter core and the cutter seat is kept synchronous, which reduces the vibration and error caused by axial deviation during the cutting process, thereby improving the processing accuracy and processing stability, and further improving the surface quality of the electrode cap.
[0018] The beneficial effects of the utility model are as follows: the utility model evenly arranges a plurality of restraining parts along the circumferential direction on the inner wall of the tool holder to correct the electrode cap that has deviated, thereby preventing the cutting surface from being uneven; and the restraining parts are detachably connected to the tool holder, which can meet the requirement that the size of the restraining parts is always compatible with the size of the electrode cap to be repaired.

[0028] The drawings are only used for illustrative purposes and should not be construed as limitations of this patent. In order to better illustrate this embodiment, some parts of the drawings may be omitted, enlarged, or reduced, and do not represent the size of the actual product.
[0029] For those skilled in the art, it is understandable that some well-known structures and their descriptions may be omitted in the drawings. The technical solution of the utility model is further described below in conjunction with the drawings and embodiments.
[0030] As shown in the attached drawings, an electrode cap grinding tool with a restraining function comprises a tool holder 1, a mounting hole 11 is passed through the tool holder 1, a tool core 2 is arranged in the mounting hole 11, and a plurality of restraining members 3 are evenly distributed on the inner wall of the mounting hole 11 along the circumference of the mounting hole 11, and the restraining members 3 are detachably connected to the tool holder 1. In this embodiment, the number of the restraining members 3 is three.
[0031] Furthermore, the inner wall of the mounting hole 11 is evenly provided with three mounting grooves 12 along the circumference of the mounting hole 11, and the restraining members 3 are arranged in the mounting grooves 12 one by one, and the restraining members 3 extend into the mounting hole 11. Specifically, the mounting grooves 12 limit the restraining members 3 therein, so as to prevent the restraining members 3 from being knocked away by the deviated electrode cap during the grinding process, thereby improving the stability of the grinding.
[0032] Furthermore, the cutter core 2 is composed of a plurality of cutting structures 21, which are arranged in a circular matrix. The cutting structures 21 include a cutting rear face 211, a positioning face 212, a cutting edge 213, and a chip removal opening 214. The cutting rear face 211 provides stable support for the cutter core 2, the positioning face 212 ensures that the tool has the correct position and direction during the machining process, the cutting edge 213 directly performs the cutting process, and the chip removal opening 214 discharges the waste chips generated during the cutting process, and they work together to achieve efficient and accurate electrode cap grinding and cutting processing. In this embodiment, there are three cutting structures 21.
[0033] Furthermore, the constraint 3 includes an arc structure 31 and a threaded hole 32 that are symmetrical in the upper and lower directions. The arc structure 31 extends into the mounting hole 11. The arc structure 31 includes a long side arc 311 and a short side arc 312. The long side arc is placed in the clockwise direction in the tool holder 1 to keep it consistent with the rotation direction of the tool core 2. The arc of the long side arc 311 is gentler than the arc of the short side arc 312 to prevent the electrode cap from hitting the arc structure 31 during rotation and causing cutting jam. The tool holder 1 is evenly distributed with a plurality of positioning holes 13 that are paired with the threaded hole 32 along the circumference of the mounting hole 11. The threaded hole 32 is connected to the positioning hole 13 by a screw 4. In the installed state, the screw 4 passes through the positioning hole 13 and is threadedly connected to the threaded hole 32, thereby fixing the constraint 3 on the tool holder 1. Specifically, during the grinding process, when the electrode cap that has deviated touches the long side arc 311 on the constraint 3, the electrode cap will be corrected, thereby preventing the electrode cap from cutting an uneven surface. When the size of the electrode cap to be repaired changes, the screw 4 connected between the threaded hole 32 and the positioning hole 13 can be removed, so that the constraint member 3 on the tool holder 1 can be replaced, so that the size of the constraint member 3 is always adapted to the size of the electrode cap to be repaired. The connection method of the constraint member 3 and the tool holder 1 is also relatively simple.
[0034] Furthermore, a plurality of chip removal holes 14 are evenly distributed along the circumference of the tool holder 1, and the chip removal holes 14 and the constraint member 3 are staggered to avoid the constraint member 3 affecting chip removal. In this embodiment, the number of chip removal holes 14 is three, and the three evenly distributed chip removal holes 14 can achieve chip removal effect to a large extent and prevent chip blockage.
[0035] Furthermore, the axes of the blade core 2 and the blade holder 1 are located on the same straight line.

For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to list all the implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection scope of the claims of the utility model.
