Clay numerical control milling clamping platform and clamping method

Abstract

The invention discloses a clay numerical control milling clamping platform and a clamping method, and belongs to the technical field of automobile clay model machining. The platform is used for solving the problems that an existing clamping platform is troublesome in alignment, poor in universality, low in precision and the like. The clay numerical control milling clamping platform comprises a T-shaped groove platform, a long bench, a short bench, a rotating shaft, a limiting block, a fixed positioning block, a movable positioning block and a fixing block. The platform is designed aiming at clay milling and clamping, the advantages of T-shaped grooves are fully utilized, the positioning block and the movable positioning block are used for realizing quick clamping and alignment, coordinatecalibration is realized by utilizing the longitudinal and transverse T-shaped grooves, therefore coordinate presetting is not needed, and generalization is realized through cooperation of the long bench, the short bench and matrix holes.

Description

technical field [0001] The invention belongs to the technical field of automobile sludge model processing. Background technique [0002] The milling of the automobile clay model is generally carried out on the sludge milling machine, and the machine tool platform of the sludge milling machine is usually a smooth platform without positioning and fastening mechanisms. [0003] At present, the common practice in the industry is to position the model on the machine tool platform through the positioning column, and the positioning column is fastened on the machine tool platform by hand-mixing resin or structural glue. Before tightening, straightening and alignment and preset coordinates are performed with machine tool assistance. There are five disadvantages of this approach: [0004] ①The process of model alignment is cumbersome and requires constant adjustment of the body angle, wasting time. [0005] ②The accuracy of model alignment is poor, and it is too much affected by h...

AI Technical Summary

Problems solved by technology

[0004] ①The process of model alignment is cumbersome, and the angle of the body needs to be adjusted continuously, wasting time

[0005] ②The accuracy of model alignment is poor, and it is too much affected by human factors

[0006] ③Repeated positioning accuracy is poor. When the model is processed for the second time, all previous alignment and clamping coordinate presets need to be done again, which is a waste of time and the accuracy is poor.

[0007] ④ Poor reliability. The model and the positioning column are fastened by the weight of the vehicle body. When processing a partial model or a split model, there will be a problem of insufficient fastening force

[0008] ⑤ Poor versatility. When this clamping is applied to cars, the universality problem is not obvious. When it is applied to trucks, because trucks are generally processed separately, it will involve different model parts for replacement. This clamping cannot be used universally for different models. piece
