Description

Technical Field

[0001] This utility model relates to a vacuum adsorption fixture, specifically a modular vacuum interchangeable adsorption fixture with wing-shaped blades, and belongs to the field of machining. Background Technology

[0002] Existing technologies frequently process wing-shaped workpieces. Wing-shaped workpieces require strict dimensional tolerances and high surface roughness. However, due to their susceptibility to deformation and difficulty in ensuring proper shape, the machining process is complex, time-consuming, and challenging. Their contour accuracy plays a decisive role in the product's flight attitude and range. Using conventional machining methods with a clamping plate and process head makes it difficult to align the part's reference edges and surfaces, and vibration occurs in thin-walled areas during wing-shaped workpiece machining, resulting in unacceptable surface roughness. Since the deformation of each part is not uniform, it is difficult to control, requiring multiple aging and reshaping processes to meet design requirements. Therefore, existing technologies for machining wing-shaped workpieces result in low processing speed, difficulty in guaranteeing machining accuracy, and low production efficiency. Thus, there is a need for a fixture to hold wing-shaped workpieces to improve production speed and quality. Summary of the Invention

[0003] The purpose of this invention is to solve the problems of low processing speed, difficulty in ensuring processing accuracy, and low production efficiency of wing-type workpieces in the prior art, and to provide a modular vacuum replaceable adsorption fixture for wing-type workpieces.

The base pipe thread connector is connected to an external vacuum pump.

[0007] Furthermore, the fixture base is an inverted 'T'-shaped housing, with a base pipe thread connector installed on the top protrusion of the fixture base, and multiple sealing plugs installed on both sides of the top protrusion of the fixture base.

[0008] Furthermore, the top of the left-wing modular vacuum platform is machined with multiple adsorption units, and two vacuum platform pipe threaded joints are installed on the side wall of the left-wing modular vacuum platform. The left wing is laid on top of the multiple adsorption units on the top of the left-wing modular vacuum platform. The left wing is installed on top of the left-wing modular vacuum platform through the first pneumatic expansion positioning pin and the second pneumatic expansion positioning pin to form a closed cavity. Each vacuum platform pipe threaded joint is inserted into the sealing plug of the fixture base for connection. The top of the left-wing modular vacuum platform is machined with multiple adsorption units, and the side wall of the right-wing modular vacuum platform is installed with two vacuum platform pipe threaded joints. The right wing is laid on top of the multiple adsorption units on the top of the right-wing modular vacuum platform. The left wing is installed on top of the right-wing modular vacuum platform through the first pneumatic expansion positioning pin and the second pneumatic expansion positioning pin to form a closed cavity. Each vacuum platform pipe threaded joint is inserted into the sealing plug of the fixture base for connection.

[0009] Furthermore, the top protrusion of the fixture base forms a sealed housing.

[0010] Furthermore, it also includes four vacuum platform positioning columns;

[0011] The fixture base has base positioning holes on both sides of the top protrusion. Two vacuum platform positioning posts are installed on the side wall of the left modular vacuum platform, and each vacuum platform positioning post on the left modular vacuum platform is inserted into the corresponding base positioning hole. Two vacuum platform positioning posts are installed on the side wall of the right modular vacuum platform, and each vacuum platform positioning post on the right modular vacuum platform is inserted into the corresponding base positioning hole.

[0012] Furthermore, it also includes four pneumatic pressure plates;

[0013] Two pressure grooves are machined on the left modular vacuum platform, and a pneumatic pressure plate is installed on each pressure groove.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1. The fixture of this application is modularly assembled with a replaceable vacuum platform, which can process two different workpieces at the same time or process two of the same workpiece at the same time. It realizes pneumatic clamping, pneumatic positioning and vacuum adsorption, eliminating manual operation, and enabling quick production changeover and quick clamping, greatly improving efficiency.

[0017] 2. The fixture of this application ensures stable machining accuracy of the workpiece during machining. After clamping with the wing-shaped vacuum adsorption fixture, the workpiece position is accurate, eliminating the need for repeated straightening of parts, reducing the labor intensity of the operator, improving machining efficiency, and making the machining accuracy of the same batch of workpieces tend to be consistent.

[0018] 3. The fixture of this application can improve production efficiency when used. After the wing vacuum adsorption fixture is used for clamping, it can achieve one clamping, reduce the number of times parts are flipped and turned, and improve processing efficiency.

[0019] 4. The part surface tolerance dimensions of the fixture in this application are qualified. After the part surface is clamped by the wing vacuum adsorption fixture, the part surface is completely in contact with the tooling. The part surface is uniformly stressed by vacuum negative pressure clamping, the cutting process is stable and chatter-free, the internal deformation force of the part is better weakened, the deformation of the part is reduced, and the external tolerance of the part surface is qualified.

[0020] 5. After the fixture of this application is clamped by the wing vacuum adsorption fixture, the parts do not need to retain a large number of process heads to ensure the part datum, the blanking is greatly reduced, and materials are saved.

[0021] 6. The fixture described in this application can serve as a reference for other similar workpieces. For thin-walled, irregularly shaped parts facing challenges such as narrow machining openings, low efficiency, and unstable quality, this method can be used as a specific innovation point to solve these problems in terms of improving quality and efficiency, and process innovation. Currently, it is mainly used in the machining of thin-walled, regular, and irregularly shaped curved surface parts. Attached Figure Description
