Description

A fixture for processing L-shaped thin-walled aluminum alloy parts

technical field

The utility model relates to a fixture for parts, in particular to a fixture for processing L-shaped thin-walled aluminum alloy parts.

Background technique

At present, the thickness of L-shaped thin-walled aluminum alloy parts on the market is 6mm, the middle part is 2.5mm, (length × width = 300 × 280), the thickness of the root of the window side is 2.7mm (the inner side has a draft angle of 1°), and the window surface The height dimension is 30mm. When processing the outer surface of the window surface (0.3 flatness requirement, roughness Ra3.2) and positioning holes of each window relative to the large surface, there are positional requirements. However, the existing processing methods for this product need to be completed in two steps, and two equipments are required, and there will be vibrations during the processing window, which will affect the processing quality and processing speed.

Contents of the invention

Aiming at the deficiencies in the above-mentioned prior art equipment, the utility model aims to provide a fixture for processing L-shaped thin-walled aluminum alloy parts, which has simple structure, convenient operation, high production efficiency and low cost.

In order to achieve the above purpose, the technical solution of the present utility model is: a fixture for processing L-shaped thin-walled aluminum alloy parts, including a fixture body for processing and fixing L-shaped thin-walled aluminum alloy parts, on the vertical large surface of the fixture body There are two positioning holes corresponding to the two reference holes on the vertical inner side of the L-shaped thin-walled aluminum alloy part. Above the fixture body, there are movable up and down and can be positioned on the inner side of the short side of the L-shaped thin-walled aluminum alloy part. There is a backing plate on the large surface of the fixture body, which can press and fix this L-shaped thin-walled aluminum alloy part and be located at the first pressing plate and the second pressing plate on both sides of this L-shaped thin-walled aluminum alloy part.

Beneficial effects of the utility model: Compared with the prior art, the utility model provides a fixture for processing L-shaped thin-walled aluminum alloy parts, which has simple structure design, convenient operation, saves operation steps, and can improve the vibration phenomenon very well , save labor and improve production efficiency.

detailed description

The utility model will be described in further detail below in conjunction with specific embodiments and accompanying drawings.

As shown in Figures 1 and 2, the utility model includes a fixture body 1 for processing and fixing L-shaped thin-walled aluminum alloy parts. On the vertical large surface of the fixture body 1, there is a There are two positioning holes 2 corresponding to the two reference holes on the straight inner side. There is a backing plate 10 above the fixture body 1 that can move up and down and can be positioned on the inner side of the short side of the L-shaped thin-walled aluminum alloy part. The large surface of the fixture body 1 has a first pressing plate 8 and a second pressing plate 11 which can press and fix the L-shaped thin-walled aluminum alloy part and are located on both sides of the L-shaped thin-walled aluminum alloy part.

The first press plate 8 and the second press plate 11 described in the utility model are rotary hydraulic angle cylinders, which are respectively located on the left and right sides of the large surface of the fixture body 1 .

The backing plate 10 of the utility model is connected with the cylinder 6, and the bottom surface of the backing plate 10 is equipped with a guide pin 18 that can cooperate with the guide hole on the top surface of the fixture body 1 .

The number of cylinders 6 described in the utility model is two, which are respectively placed on both sides of the fixture body 1, and a pressure regulating valve is arranged on the cylinder 6 and the gas source connecting pipe.

As shown in Figure 2, when the utility model is used for processing, first use the two positioning holes 2 on the large surface of the fixture body and the reference hole on the L-shaped thin-walled aluminum alloy part to perform precise positioning, and use the left and right two-rotation hydraulic angle cylinders 8 , 11 compression, then use 2 cylinders 6 to put the top of the backing plate 10 close to the inner side of the product window, the cylinder is guided by the guide pin 18 when it is pushed upwards, so that the backing plate 10 will not be stuck when it moves upwards. Pressure regulating valve 5 is housed on cylinder 6 and gas source 3 connecting pipe 4, regulates the size of air pressure, guarantees that product will not be fixedly deformed because backing plate 10 is fixed. The backing plate 10 is close to the product surface with an inclination of 1° to the left and right, so that the backing plate 10 can fit the product better, so that the clamping can be completed at one time when the machine window outside the processing window is processed. After the product is processed, the cylinder 6 moves downward. Thereby drive backing plate 10 to leave product window inner surface, unclamp rotary oil pressure angle cylinder 8,11 pressing plate, take out product.

When using this method to process the window, the operation that originally required two processes is simplified to one step, and the vibration phenomenon is well improved, and the processing quality and processing efficiency are further improved.

The technical solutions provided by the embodiments of the present invention have been introduced in detail above. In this paper, specific examples have been used to illustrate the principles and implementation methods of the embodiments of the present invention. The descriptions of the above embodiments are only applicable to help understand the present invention. The principle of the embodiment; at the same time, for those of ordinary skill in the art, according to the embodiment of the present invention, there will be changes in the specific implementation and the scope of application. Utility model restrictions.
