Problems solved by technology

However, in the case of this method, there are problems that a special tool is required in order to detach the cap-shaped electrode tip from the grinding table, and there is a problem that the cap-shaped electrode tip may be damaged during detachment.
In addition, there is a problem that the state of contact with the blade of the tool may change depending on the fitting depth of the cap-shaped tip, making it difficult to perform grinding with a certain accuracy.

Embodiment Construction

[0031] Hereinafter, preferred embodiments of the present invention will be shown with reference to the drawings.

[0032] figure 1 is a front view showing an embodiment of the present invention, figure 2 and image 3 It is a plan view and a side view showing a grinding table. In the drawings, 1 is a grinding head, and 2 is a grinding table provided under the grinding head 1 .

[0033] The grinding head 1 has a shaft portion 1b for installation on a drill press at the center of the upper part of a cylindrical head body 1a, and the shaft portion 1b is mounted on a rotating shaft (not shown) of the drill press, thereby making the grinding head 1 can be freely rotated, and can be lifted and lowered freely. In addition, the cutter blade 1c for grinding and cutting is provided inside the head body 1a, and the lower opening end 1d of the head body 1a abuts against the guide plate 6 of the grinding table 2 to be positioned.

[0034] In this way, the dressing head 1 is used to be...

Abstract

The invention relates to an electrode tip grinding device, which is a drilling machine type electrode tip grinding device, comprising: a grinding head (1), which has a built-in tool blade (1c), and can freely rotate and lift freely; and a cap A grinding table (2) for placing a shape electrode head, which is arranged below the above-mentioned grinding head (1), and an electrode head holding mechanism is provided on the grinding table (2), and the electrode head holding mechanism has: a chuck (9), which can insert the front end into the back side recess (30a) of the cap-shaped electrode tip (30), and a tapered surface (9a) is formed on the inner peripheral surface of the front end; and a bolt-shaped member (10), It can move up and down in the center of the chuck (9), and a tapered surface (10a) that can be in close contact with the tapered surface (9a) is formed at the front end. The cap-shaped electrode tip (30) is fixed by opening the front end of the collet. Accordingly, the cap-shaped electrode tip for welding can be easily and accurately held.

Description

technical field [0001] The present invention relates to a tip dresser device including a dresser base capable of easily and accurately holding a cap tip for welding. Background technique [0002] Conventionally, for example, in automobile assembly plants, etc., resistance spot welding of workpieces is performed using a welding torch attached to the tip of a robot arm. If welding is repeated, the cap-shaped electrode tip used in this resistance spot welding will be worn out, deformed, or welding shavings will adhere to the surface, so that good welding cannot be achieved. Therefore, when there are more than a certain number of welding points, it is necessary to cut the surface with a lathe or a milling machine to return it to a predetermined shape. However, cutting with a lathe or the like requires a certain degree of proficiency, and thus there is a problem that it is difficult for beginners. [0003] In order to solve this problem, the applicant of the present invention p...
