Description

Technical Field

[0001] The utility model relates to the technical field of tooling fixtures, in particular to a tooling fixture used for producing special-shaped parts. Background Art

[0002] In the production process of special-shaped parts, tooling and fixtures play a key role. Tooling and fixtures are specially designed and manufactured devices used to fix, position and support workpieces to ensure accuracy and stability during the processing. The production of special-shaped parts usually involves the manufacturing of parts with non-standard shapes, complex structures or special requirements. These parts may be made of various materials and have unique geometric features and dimensional requirements.

[0003] The positioning and assembly of traditional tooling and fixtures for the production of special-shaped parts need to be closely matched with the positioning holes and bottom surfaces of the parts. Therefore, the fixture design may not have automated positioning and fixing functions, which requires manual adjustment to achieve the ideal position. This adjustment process may be time-consuming and may reduce production efficiency. In addition, traditional tooling and fixtures for the production of special-shaped parts may have slight offsets during processing, which may affect the accuracy and consistency of the parts during the processing process, and may also cause inaccurate processing or non-compliance with requirements.

[0004] Therefore, those skilled in the art provide a fixture for producing special-shaped parts to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to propose a tooling fixture for the production of special-shaped parts. The tooling fixture for the production of special-shaped parts slides a rubber fixing column in a sliding hole. When the rubber fixing column is tightly fitted with the workpiece, it is clamped with the limiting hole through a limiting plate. The workpiece can be stably supported during the clamping process, avoiding shaking or displacement of the workpiece, ensuring the stability and accuracy of the processing, and the clamping of the limiting plate and the limiting hole ensures that the workpiece is clamped in a predetermined position. This clamping method can provide a higher clamping force and firmness, ensuring that the workpiece will not move during operations such as turning, ensuring processing accuracy and safety. In addition, the material of the rubber fixing column has certain buffering properties, which can provide certain protection when it is tightly fitted with the workpiece, avoiding damage or scratches on the workpiece surface.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A tooling fixture for producing special-shaped parts, comprising a tooling fixture, wherein a support plate is fixedly connected to the lower part of the front end of the outer wall of the tooling fixture;

[0008] A fixing plate is fixedly connected to the front end of the upper surface of the supporting plate, and a positioning plate is arranged at the upper end of the fixing plate.

[0009] Through the above technical scheme, the first positioning hole and the second positioning hole are respectively assembled through the first positioning rod and the second positioning rod, the bottom surface of the part fits tightly with the bottom surface of the tooling, and the part processing hole is concentric with the outer circle of the tooling to achieve turning processing. In this way, the part can be quickly positioned and stably fixed, avoiding the time waste of manually adjusting the position. The design of the tooling fixture ensures the accurate positioning of the part and the tooling, reduces the error and adjustment times during the processing, thereby improving the processing efficiency, and the positioning assembly of the tooling fixture can ensure the precise alignment between the part and the tooling, so that the part remains stable during the processing. At the same time, the tight fit between the bottom surface of the part and the bottom surface of the tooling and the concentricity of the part processing hole and the outer circle of the tooling ensure that the precision requirements during the processing are met and the qualified rate of the product is improved. In mass production, the tooling fixture can be used multiple times without the need for adjustment each time, effectively saving manpower and time costs. In addition, since the accurate positioning and stability during the processing are guaranteed, the scrap rate and rework rate are reduced, further reducing the production cost.

[0010] Furthermore, the front end and the rear end of the upper surface of the fixing plate are both provided with a second positioning hole and a first positioning hole;

[0011] Through the above technical solution, by opening the second positioning hole and the first positioning hole on the front and rear ends of the upper surface of the fixed plate, a symmetrical positioning plate can be easily realized. By positioning in two directions, the position and posture of the symmetrical positioning plate can be ensured to be consistent.

[0012] Furthermore, a second positioning rod is snap-fitted inside the second positioning hole;

[0013] Through the above technical solution, the second positioning rod can be tightly fixed in the hole, thereby providing precise positioning. This snap-fit ​​can eliminate looseness or swing between the positioning hole and the fixing rod, ensuring the positioning accuracy and stability of the workpiece during processing.

[0014] Furthermore, a workpiece is clamped and matched inside the positioning plate, and sliding holes are provided at the front ends of the outer walls on both sides of the positioning plate;

[0015] Through the above technical solution, the workpiece can be adjusted by moving the rubber fixing column in the sliding hole to ensure that the workpiece can be accurately positioned at the required position.

[0016] Furthermore, a rubber fixing column is slidably connected inside the sliding hole, and one end of the rubber fixing column close to the center of the positioning plate is tightly fitted with the outer wall of the workpiece;

[0017] Through the above technical solution, the rubber fixing column is closely fitted to the outer wall of the workpiece, so that the stability and fixation of the workpiece can be increased. The high compressibility of the rubber enables it to fully contact the surface of the workpiece and adapt to irregular surfaces. This fitting design can prevent the workpiece from accidentally moving or displacing during the processing process, ensuring that the workpiece maintains a stable positioning position.

[0018] Furthermore, a plurality of limiting holes are provided inside the rubber fixing column, and limiting rods are provided on both sides of the upper surface of the positioning plate;

[0019] Through the above technical solution, multiple positioning options can be provided through the multiple limiting holes inside the rubber fixing column. According to the size and shape of the workpiece, a suitable limiting hole can be selected for positioning. This can flexibly adapt to the positioning requirements of different workpieces and provide more position options, thereby increasing the flexibility and accuracy of positioning.

[0020] Furthermore, the limiting rods are all slidably connected to the inside of the limiting hole;

[0021] Through the above technical solution, flexible positioning adjustment can be achieved through the internal sliding connection between the limit rod and the limit hole. According to actual needs, the position of the limit rod in the limit hole can be adjusted to achieve fine-tuning and precise positioning of the workpiece, which makes the positioning process more flexible and convenient and can adapt to the positioning needs of different workpiece sizes and shapes.

[0022] Furthermore, a first positioning rod is snap-fitted inside the first positioning hole;

[0023] Through the above technical solution, the precise positioning function can be achieved through the internal snap-fitting of the first positioning hole, and the first positioning rod and the first positioning hole cooperate to form a tight connection, which can ensure the precise positioning of the connecting plate during the processing.

[0024] The utility model has the following beneficial effects:

In this way, the part can be quickly positioned and stably fixed, avoiding the time waste of manually adjusting the position. The design of the jig ensures the accurate positioning of the part and the jig, reduces the error and adjustment times during the processing, and thus improves the processing efficiency. The rate is high, and the positioning and assembly of the jig can ensure the precise alignment between the part and the jig, so that the part remains stable during the processing.
