Base adjusting and fixing mechanism of aircraft titanium alloy part machining tool table

Abstract

The invention relates to a base adjusting and fixing mechanism of an aircraft titanium alloy part machining tool table. The mechanism is an auxiliary device of a machining part of a machine tool. Thedevice comprises four parts, namely a base adjusting and fixing mechanism, a left lifting tight pressing mechanism, a right lifting tight pressing mechanism and an X-direction tight pressing mechanism, wherein the left lifting tight compressing mechanism and the right lifting tight compressing mechanism are fixedly installed on the base adjusting fixing mechanism, and are connected with the base adjusting and fixing mechanism to form a threaded transmission and spline transmission cooperating relation; and the X-direction tight pressing mechanism is fixedly installed on the base adjusting andfixing mechanism. According to the mechanism, rapid adjustment can be realized manually, automatic adjustment of the clamping size and position and tight clamping of a set load are achieved through amotor drives the equipment, a blank is driven by the motor to ascend or descend and rotate to realize multi-face machining.

Description

technical field [0001] The invention belongs to the field of mechanical manufacturing, and in particular relates to an adjusting and fixing mechanism for a base of a processing tooling table for aircraft titanium alloy parts, which is an auxiliary device for processing parts by a machine tool. Background technique [0002] Before the machining parts are machined by the machine tool, the blank first needs to be fixed on the working plane of the machine tool. Now, the fixing of the part blank is mainly fixed on the working plane of the machine tool by the threaded pressure plate. This method requires the worker to use a wrench to tighten and fix it manually. The operation is more troublesome, and the pressing force is inconsistent each time. The pressing force of the pressing plate is also inconsistent, resulting in different degrees of fit between each part and the working plane of the machine tool. In addition, the processing positioning position of each part is also incons...

Problems solved by technology

Now, the fixing of the part blank is mainly fixed on the working plane of the machine tool by the threaded pressure plate. This method requires the worker to use a wrench to tighten and fix it manually. The operation is more troublesome, and the pressing force is inconsistent each time. The pressing force of the pressing plate is also inconsistent, resulting in different degrees of fit between each part and the working plane of the machine tool

In addition, the processing positioning position of each part is also inconsistent, resulting in a relatively large difference in the processing accuracy of the same part of the same batch.

[0003] A large number of titanium alloy materials are used in the aircraft structure, and the processing of aircraft titanium alloy parts is difficult, easy to deform, and the structure of the parts is complex

At present, when the factory processes titanium alloy parts, the blank is fixed on the working surface of the machine tool, the first side is roughly machined, and then the second side is processed. After heat treatment, the first and second sides are finished, so one part is processed. Need to go through such repeated clamping, and will bring a considerable workload

The clamping method of the parts is to use the bolt pressing plate, the work intensity of the workers is high, and the clamping time of the larger parts can even exceed 4 hours, and the clamping efficiency is very low.

Due to the small tolerance range and high precision of aircraft titanium alloy parts, repeated clamping will bring large errors, resulting in parts being out of tolerance and scrapped, causing serious losses to the factory
