High-frequency quenching clamp using marble as locating block

Abstract

The invention provides a high-frequency quenching clamp using marble as a locating block. The high-frequency quenching clamp comprises supporting feet, a clamp body, an adjusting board, a guide seat, a side board, the marble locating block, a support and an inducing conductor. The clamp body is installed at the upper portions of the supporting feet. The adjusting board is installed on one side of the upper portion of the clamp body and at least two adjusting supports are installed on the other side of the upper portion of the clamp body. The adjusting supports are horizontally provided with adjusting screws perpendicular to the adjusting board. The side board is installed on the side face, close to the adjusting screws, of the adjusting board. The guide seat is installed on the upper surface of the adjusting board. The two adjacent side faces of the marble locating block are installed on the side board and the adjusting board respectively. The support is further arranged at the end, away from the guide seat, of the adjusting board and provided with a locating screw. The inducing conductor is located above the marble locating block and formed by welding an induction coil and a copper pipe into a whole. The inducing conductor is welded to a collection board. By the adoption of the high-frequency quenching clamp, the part quenching accuracy is improved, the rate of finished products is increased, production cost is reduced, and batch production of the products is guaranteed.

Description

technical field [0001] The invention belongs to the field of fixtures, in particular to a high-frequency quenching fixture using marble as a positioning block. Background technique [0002] The material of the positioning block in the currently used high-frequency quenching fixture is steel. Because the electromagnetic field expands outside the coil during quenching, the positioning block material is steel, so it is also heated after conducting electricity, which not only causes energy loss, but also leads to the positioning reference surface and positioning of the parts. The hardness of the points between the contact surfaces of the blocks will be higher. Since the positioning reference surface of the part needs to be finished in the subsequent process, the tool is extremely worn during finishing, which increases the frequency of tool change and increases the cost of the tool. SUMMARY OF THE INVENTION [0003] Aiming at the deficiencies in the prior art, the present inven...

Problems solved by technology

[0002] Part of the material of the positioning block in the current high-frequency quenching fixture is steel, because the electromagnetic field extends beyond the coil during quenching, and the material of the positioning block is steel, so it is also heated after conducting electricity, which not only causes energy loss, but also causes the positioning reference plane of the part to be different from the positioning The hardness of the points between the contact surfaces of the blocks will be higher. Since the positioning reference plane of the part needs to be finished in the subsequent process, the tool is extremely worn out during finishing, which increases the frequency of tool change and increases the cost of the tool.
