Description

Technical Field

[0001] This utility model relates to the field of machining fixtures, specifically to a hydraulic machining fixture for a pump body. Background Technology

[0002] The electric pump housing is one of the main components of an automotive electric pump. Any dimensional deviation in the housing will affect the assembly and performance of the generator pump. The automotive electric pump housing is small and difficult to manufacture. Positioning is required during processing, and its specific shape makes it difficult to clamp using traditional fixtures, resulting in insecure clamping, low clamping accuracy, and hindering processing. Summary of the Invention

[0003] To address the shortcomings of the existing technology, this utility model provides a hydraulic machining fixture for pump bodies, which has a simple structure, good clamping and positioning stability, high positioning accuracy, and is convenient for processing.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A hydraulic clamping fixture for a pump body is characterized by comprising a left vertical plate, a right vertical plate, and a fixture base plate. The left and right vertical plates are arranged opposite to each other. The fixture base plate is disposed on the top surface of the left and right vertical plates. The fixture base plate is provided with a cylindrical positioning pin and a diamond-shaped pin. The fixture base plate is also provided with three equal-height support columns, which are arranged in a triangular pattern. Each equal-height support column has a lever clamping cylinder on one side, and the pressure arm of the lever clamping cylinder faces the top surface of the equal-height support column.

[0006] Furthermore, the base plate of the fixture has a hollowed-out circular hole in the middle.

[0007] Furthermore, the cylindrical locating pins and the rhomboid pins are diagonally distributed.

[0008] Furthermore, the fixture base plate is provided with multiple edge limiting posts.

[0009] Furthermore, a connecting plate is provided between the left upright plate and the right upright plate.

[0010] The advantages of this utility model include: the fixture has a simple structure, is easy to clamp, has high positioning accuracy, provides high clamping stability for the pump body, and helps to improve the machining accuracy of the pump body. Attached Figure Description

[0011] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0012] The present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0013] One such Figure 1 The hydraulic machining fixture for the pump body shown includes a left vertical plate 1, a right vertical plate 2, and a fixture base plate 3. The left vertical plate 1 and the right vertical plate 2 are arranged vertically opposite each other, and the fixture base plate 3 is located on the top surface of the left vertical plate 1 and the right vertical plate 2. The fixture base plate 3 has a clamping station, which is equipped with cylindrical positioning pins 4 and diamond-shaped pins 5 arranged diagonally along the pump body. The fixture base plate 3 is also equipped with three equal-height support columns 6, which are distributed in a triangle and support the edge of the pump body. Each equal-height support column 6 has a lever clamping cylinder 7 on one side, with the pressure arm of the lever clamping cylinder 7 facing the top surface of the equal-height support column 6, for clamping the end face of the pump body.

[0014] like Figure 1 The fixture base plate 3 shown has a hollowed-out circular hole in the middle, which is directly opposite the pump body shaft hole.

[0015] To ensure the pump body remains stable during machining after clamping and to further improve machining accuracy, multiple edge limiting posts 8 are provided on the fixture base plate 3. The edge limiting posts 8 limit the pump body at the edge, thereby preventing the pump body from rotating during machining.

[0016] To improve the structural stability of the fixture base plate 3, a connecting plate 9 is provided between the left upright plate 1 and the right upright plate 2 in this embodiment.

[0017] The technical solutions provided by the embodiments of this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the embodiments of this utility model. The description of the above embodiments is only for helping to understand the principles of the embodiments of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the embodiments of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
