Description

Technical Field

[0001] The utility model relates to the technical field of component improvement design of an electrode cap grinding machine, in particular to a blade holder for electrode cap grinding. Background Art

[0002] The quality of the end face of the electrode cap in resistance welding directly affects the welding strength. In order to ensure the welding quality, the electrode cap needs to be ground after welding a certain number of welding points to remove the oxide layer on the end face of the electrode cap. Electrode grinding is to grind the surface of the electrode cap after welding into a specified shape and surface roughness by using a blade to ensure the stability and reliability of the welding spot. At present, there are two main grinding methods. One is manual method, using ordinary files to trim the electrode cap. However, the efficiency and reliability of manual grinding of electrode caps are very low, and the welding quality is unstable. The other method is to use a grinder to grind the electrode cap, such as a handheld pneumatic electrode grinding planer. When grinding, the cutter head is directly inserted into the electrode for grinding. The advantage of this dressing equipment is easy operation. The disadvantage is that the recoil force is large during grinding, and the manual grip is unstable. In addition, the unit price of each tool is high. If it is equipped at each workstation in the welding workshop, the investment is too large. There is also a movable electrode grinder. When in use, the welding clamp is placed in an adjustment state, and the electrode is inserted into the cutter head for grinding. The advantage of this dressing equipment is that two electrodes can be ground at one time, but the disadvantage is that it is expensive.

[0003] In the prior art, the patent with announcement number CN218311256U discloses an electrode cap grinding blade, a tool holder assembly and an electrode cap grinding machine, wherein the electrode cap grinding blade comprises a blade body, the blade body comprises a blade face, a first cutting edge and a second cutting edge, the first cutting edge is used to grind the end face of the electrode cap, the second cutting edge is used to grind the side face of the electrode cap, a plurality of circular arc teeth are arranged concentrically, and one end of the plurality of circular arc teeth forms the first cutting edge. The beneficial effect of the utility model is that the blade body is provided with a first cutting edge for grinding the end face of the electrode cap, and one end of the plurality of concentrically arranged circular arc teeth forms the first cutting edge, so that the blade body can grind the end face of the electrode cap into a relatively rough surface with a plurality of annular grooves, thereby increasing the resistivity of the electrode cap, so that the aluminum welding electrode cap has the effect of fast heating of the weld point and deep molten core during the welding process, thereby enhancing the welding strength of the aluminum welding and improving the welding quality of the electrode cap. In the above technical scheme, the shape and structural design of the blade and the tool holder are relatively complex, and the processing and manufacturing are relatively difficult.

[0004] The patent with the announcement number CN201147867 discloses an electrode cap dressing device used in the field of electrode cap dressing of welding tongs, comprising a grinding tool holder (2), a grinding blade (3), a grinding blade fixing sleeve (4), a grinding tool holder fixing rod (7), and a grinding tool holder fixing clamp (8). The grinding tool holder (2) is a hollow cylindrical structure, and two corresponding rectangular holes (9) penetrating the grinding tool holder (2) are processed on the grinding tool holder (2). The grinding blade (3) is a sheet-mounted structure and is installed in the hole groove (9). The grinding blade fixing sleeve (4) is set to a shape matching the outer diameter of the grinding tool holder (2). The grinding tool holder fixing rod (7) is connected to a bench drill (1) by clamping the grinding tool holder fixing clamp (8).

The side of the second chip removal port 24 horizontally passes through the mounting portion 26, and the size of the second chip removal port 24 is larger than the first chip removal port 22. The design of the chip removal port with enlarged size and the through-type design of the top, bottom and sides can facilitate rapid chip removal and prevent the problem of copper chip blockage.

[0043] Furthermore, the second mounting hole 27 is a screw hole, and a through hole is processed in the direction of the accommodating cavity, so that the bolt 3 can be conveniently inserted into the through hole and then threadedly connected to the second mounting hole 27.

In addition, three first mounting holes 23 are processed along the circumferential direction on the top of the mounting plate 25, and the positions of the three mounting holes are designed to avoid installing the tool holder 2 in reverse, among which two first mounting holes 23 are symmetrically arranged, and the remaining first mounting holes 23 are located at positions that divide the circumference into four equal parts. Of course, other auxiliary positioning and guiding components can also be designed on the tool holder 2, such as guide ribs, etc., so as to facilitate the accurate determination of the installation direction of the tool holder 2.

[0044] In addition, if Fig.11 As shown, the side of the mounting portion 26 may also be provided with a snap-fit ​​protrusion 28, and the snap-fit ​​protrusion 28 is mounted on the machine platform. Compared with the flange connection method in the first embodiment, the snap-fit ​​structure can also be used to fix the tool holder 2 on the workbench of the grinding machine. In addition, the shapes of the blade 1 and the tool holder 2 may also be corresponding mirror designs. Since the grinding machine can grind the electrode cap forward and reversely, the blade 1 and the tool holder 2 also have forward and reverse directions. Therefore, the mirror design of the blade 1 and the tool holder 2 can be used to match the forward or reverse working mode of the motor working state on the grinding machine, which will not be elaborated here.
