Multi-model bit leg journal texture machining clamp

Abstract

The invention provides a multi-model bit leg journal texture machining clamp which further comprises a tool for assisting a bit leg journal to coincide with the rotating center line of the clamp, and the clamp comprises a supporting plate, a left side plate, a right side plate, a rotating handle, a V-shaped block, a fixing auxiliary plate, an arc-shaped fixing supporting block, a sliding groove, a fine adjustment block, a lead screw and a balancing weight. The auxiliary tool comprises a clamp centering box, a support and a pointer displayer. According to the multi-model bit leg shaft neck texture machining clamp, rapid assembly and replacement during bit leg shaft neck machining are achieved, an auxiliary tool rapidly finds the coincidence position of the bit leg shaft neck and the rotating neutral line of the clamp, and laser focusing irregularity caused by shaft neck jumping during laser texture machining is reduced; the situation that the texture machining depth and shape do not reach the standard is avoided, the earlier-stage preparation work during machining is effectively shortened, machining of different models can be achieved through one clamp, and the machining efficiency is greatly improved.

Description

Technical field: [0001] The invention relates to a multi-model tooth palm journal texture processing fixture, in particular to assembling and debugging during the tooth palm journal texture processing. Background technique: [0002] At present, it has been proved by experiments that texture processing on the surface of the tooth palm can effectively improve the service life of the drill bit. The texture processing of the tooth palm journal is completed by a laser marking machine. However, due to the special structural characteristics of the tooth palm To meet the processing requirements, special fixtures are required to assemble the tooth palms, but the existing tooth palm fixtures are mostly suitable for machine tool assembly, and there is no special fixture suitable for laser ablation processing of the tooth palm journals, and when processing different types of tooth palms. The positioning component - V block needs to be replaced, and it needs to be debugged again to ensur...

Problems solved by technology

[0002] At present, it has been proved by experiments that texture processing on the surface of the palm journal can effectively improve the service life of the drill bit. The texture processing of the palm journal is made by The laser marking machine is completed, but due to the special structural characteristics of the palm and the processing requirements, a dedicated jig is required to assemble the palm. However, the existing palm fixtures are mostly suitable for machine tool assembly, and are not suitable for the journal of the palm. The special fixture for laser ablation processing, and the positioning part-V block needs to be replaced when processing different types of palms, and it needs to be re-adjusted to ensure that the rotation centerline of the palm journal coincides with the rotation centerline of the fixture to ensure that the weaving The runout of the textured bearing surface is within the expected error range, and finally ensure that the depth and diameter of the textured processing reach the predetermined value

The cumbersome assembly method, the processing fixture for a single model and the lack of debugging equipment lead to the inability to process the palm texture in batches. Therefore, it is necessary to propose a further solution to the above problems
