Problems solved by technology

We found that: in the case of mass production, the use of No. 20 steel, according to the carburizing depth of 0.8 ~ 1.2mm, the positioning and clamping V-shaped block made of heat treatment hardness HRC58 ~ 64 wears quickly, especially the V-shaped surface wears quickly. It is not conducive to ensuring the quality of cylindrical workpieces; in addition, the V-shaped surface needs to be repaired frequently, which also affects production efficiency

Embodiment 1

[0015] like figure 1 As shown, a V-shaped block has a V-shaped surface 1 on the V-shaped block, and a groove is opened on the V-shaped surface, and cemented carbide 2 matching the size of the groove is welded in the groove.

[0016] The manufacture method of above-mentioned V-shaped block:

[0017] First, make a groove on the V-shaped surface of the V-shaped block;

[0018] Then, put cemented carbide that matches the size of the groove into the opened groove and weld it;

[0019] Finally, grind the V-shaped surface welded with cemented carbide.

[0020] Working principle of the present invention:

[0021] During the operation of the present invention, the cylindrical workpiece is placed between the V-shaped surfaces 1 of the V-shaped block on which the cemented carbide 2 is fixed to perform clamping, positioning, inspection or correction, and marking.

Abstract

The invention relates to a V-shaped block which is technically characterized in that grooves are arranged on a V-shaped surface, and hard alloys matching with the grooves in size are fixed in the grooves. A manufacturing method comprises the following steps: firstly, processing the grooves on the V-shaped surface of the V-shaped block; secondly, placing the hard alloys in the processed grooves, and fixing the alloys; and finally, grinding the V-shaped surface on which the hard alloys are fixed. By mounting the extremely wearable hard alloys fixedly on the V-shaped block, the invention can reduce abrasion of the V-shaped surface, thereby prolonging the service life of the V-shaped block.

Description

technical field [0001] The invention belongs to a process device in the technical field of mechanical processing, and in particular relates to a V-shaped block used for clamping and positioning a cylindrical workpiece in the process of mechanical processing. The invention also relates to a manufacturing method of the V-shaped block. Background technique [0002] V-shaped block is a component commonly used in machining to clamp and position cylindrical workpieces. [0003] There are national standards for the manufacturing method of the V-shaped block used for clamping and positioning. There are such standards in the "Machine Tool Fixture Design Manual (2)" edited by Yang Liming, which is published by the National Defense Industry Press. ISBN: 7-118-01509-1, the standard has national standard GB / T2208-91 and so on. The above standards require that the V-shaped block is made of No. 20 steel, the carburizing depth is 0.8-1.2mm, and the heat treatment hardness is HRC58-64. We...
