Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a clamp for processing split cone parts. Background Art

[0002] In the field of mechanical processing, the processing of thin-walled and complex-shaped split cone parts has always been a technical difficulty. Such parts usually have the following characteristics: first, their wall thickness is very thin, often only about 2mm, which makes the parts very easy to deform due to uneven force during processing; second, the shape of the parts is a conical ring split, lacking conventional clamping positions, further increasing the difficulty of processing; finally, due to the high processing accuracy requirements of the parts, any slight deformation may cause the parts to fail to meet the use requirements.

[0003] Traditional fixture design often has difficulty in taking into account the thin-wall characteristics of parts and the high-precision processing requirements. On the one hand, if the clamping force of the fixture is too large, although it can ensure the stability of the part during the processing, it is also easy to cause the part to deform due to excessive force, thus affecting the processing accuracy; on the other hand, if the clamping force of the fixture is too small, although it can avoid part deformation, it may not ensure the stability of the part during the processing, thus affecting the processing efficiency and part quality.

[0004] Therefore, how to design a fixture that can ensure that the parts do not deform during processing and meet the requirements of high-precision processing has become a technical problem that needs to be solved in the field of mechanical processing. Although there are some fixture designs for thin-walled parts on the market, they often have problems such as complex structure, high manufacturing cost, and inconvenient operation, which makes it difficult to meet the needs of large-scale production and practical applications.

[0005] In view of this, the utility model proposes a fixture for processing split conical parts, aiming to achieve high-precision processing of parts through a simple and practical structural design, while reducing the manufacturing cost and operating difficulty of the fixture, and improving processing efficiency and part quality. Utility Model Content

[0006] In order to solve the above problems, the utility model provides a clamp for processing split conical surface parts, which can realize high-precision processing of split conical surface parts, while reducing the manufacturing cost and operation difficulty of the clamp, improving processing efficiency and part quality, and meeting the needs of large-scale production and practical applications.

[0007] The technical solution of the utility model is as follows:

[0008] A fixture for machining a split conical part. The split conical part consists of an upper L-shaped plate, a split conical surface, and a lower L-shaped plate. The fixture includes a positioning seat, a positioning block, a conical surface pressing plate, and a flat pressing plate.

The flat pressing plate is fixed on the positioning seat, and a pressing groove is provided at the bottom of the flat pressing plate, which cooperates with the upper L-shaped plate to press and hold. The positioning block is fixed on the side wall of the positioning seat and abuts against the side of the split conical part.

[0009] It also includes a shim block, and the positioning seat is fixed on the shim block.

[0010] The positioning seat is fixedly connected to the shim block by screw one.

[0011] A positioning pin is installed between the positioning seat and the shim block.

[0012] The conical surface pressing plate includes a conical surface pressing plate one and a conical surface pressing plate two, and the conical surface pressing plate one and the conical surface pressing plate two are respectively arranged at the top of the split conical part.

Specific embodiments

[0026] As Figures 1 to 4 shown, the fixture for machining a split conical part mainly consists of a positioning seat 1, a positioning block 2, conical pressing plates (including a first conical pressing plate 3 and a second conical pressing plate 4), a flat pressing plate 5, a cushion block 6 and various fixing screws. In this embodiment, the screws are all internal hexagonal socket head cap screws.

[0027] The split conical part 13 is successively composed of an upper "L" - shaped plate, a split conical surface and a lower "L" - shaped plate. This structural feature requires the fixture to be able to effectively position and clamp each part of it.

[0028] The side surface of the positioning seat 1 is designed to be in a shape that matches the inner side of the split conical surface of the split conical part 13, so as to be able to closely fit the part and provide stable support. The bottom surface of the upper "L" - shaped plate abuts against the top of the positioning seat 1, further enhancing the stability of the part.

[0029] The conical surface pressing plate includes the first conical surface pressing plate 3 and the second conical surface pressing plate 4, which are respectively arranged at the top of the split conical surface part 13. The conical surface pressing plate is provided with a conical surface that matches the outer side of the split conical surface. By pressing the part, it can prevent the part from moving or deforming during the processing. The first conical surface pressing plate 3 and the second conical surface pressing plate 4 are firmly fixed on the positioning seat 1 through the second screw 9 and the third screw 10 to ensure the uniform distribution of the clamping force. Specifically, a long slot and a threaded hole are provided on the conical surface pressing plate. The cylindrical head of the second screw 9 is screwed downward into the threaded hole of the conical surface pressing plate. A blind hole that matches the cylindrical head of the second screw 9 is provided on the positioning seat 1. The third screw 10 passes through the long slot on the conical surface pressing plate and is screwed into the threaded hole provided on the positioning seat 1.

[0030] The flat pressing plate 5 is fixed on the positioning seat 1, and a pressing groove that cooperates with the upper "L"-shaped plate for pressing is provided at the bottom. This design can effectively fix the upper "L"-shaped plate and prevent it from shaking or displacing during the processing. The flat pressing plate 5 is connected to the positioning seat 1 through the fourth screw 11 to ensure the firmness of the connection.

[0031] The positioning block 2 is fixed on the positioning seat 1 and abuts against the side surface of the split conical surface part 13. The main function of the positioning block is to further limit the movement of the part and improve the accuracy of positioning. The positioning block 2 is connected to the positioning seat 1 through the fifth screw 12 to ensure its stability during the processing.

[0032] The cushion block 6 is used to support the positioning seat 1 to ensure the stability of the entire fixture on the workbench. The positioning seat 1 is fixedly connected to the cushion block 6 through the first screw 8. At the same time, a positioning pin 7 is also installed between the positioning seat 1 and the cushion block 6 to further enhance the firmness and accuracy of the connection.

[0033] The fixture for processing the split conical surface part of the utility model has the advantages of simple structure, accurate positioning, uniform clamping force, etc., and can effectively improve the processing accuracy and stability of the split conical surface part.
