Description

Technical Field

[0001] This invention relates to the field of positioning and clamping technology, specifically a clamping fixture for turning the outer diameter of a machine. Background Technology

[0002] Regarding the attached Figure 1 The part (9) shown has an outer arc surface structure. The part (9) includes a main board (901) and a connecting plate (902) vertically connected to the left and right ends of the main board. A positioning insert (903) extends laterally below the connecting plate (902) away from the main board (901). Currently, the processing methods used for the part (9) are single-piece milling or grinding, which have low processing efficiency and cannot be applied to the mass production of parts. Special clamping and positioning fixtures need to be designed for auxiliary processing. Summary of the Invention

[0003] The purpose of this invention is to provide a clamping fixture for the outer diameter of a vehicle to solve the technical problems in the background art.

[0004] To achieve the aforementioned objectives, the present invention provides the following technical solution:

[0005] A clamping fixture for the outer diameter of a machine tool includes a positioning base. The positioning base includes a clamping end and a support platform. The clamping end is fixed to the left side of the support platform. Both the clamping end and the support platform are cylindrical structures and are coaxially arranged. The support platform includes a mounting block. A slot is provided around the outer side of the mounting block along its outer wall, with the opening of the slot laterally facing away from the clamping end. A pressure cap is detachably mounted on the right side of the mounting block, abutting against the mounting block. The pressure cap is a disc structure and is coaxially arranged with the mounting block. A recessed storage groove is provided on the side of the pressure cap facing the positioning base. The axis of the storage groove coincides with the axis of the pressure cap. Parts are sequentially assembled side by side along the outer side of the mounting block between the slot and the storage groove. Positioning plates on the parts are respectively inserted into the slot and the storage groove.

[0006] It also includes an outer clamping ring, which is a circular ring structure. The part is clamped inside the outer clamping ring. The outer clamping ring is coaxially arranged with the support platform. The outer clamping ring has an opening, and a connector is provided at the opening to connect and fix the two ends of the opening. The width of the outer clamping ring is smaller than the length of the main board on the part.

[0007] The plane containing the outer circular sidewall of the pressure cap is lower than the plane containing the main board of the component.

[0008] The thickness of the sidewall of the storage compartment gradually increases towards the bottom of the storage compartment.

[0009] The width of the slot gradually decreases towards the clamping end.

[0010] The mounting block has a hollow structure, and the pressure cap is fixedly connected to the mounting block by screws.

[0011] The pressure cap has several positioning through holes equidistantly arranged along the axial direction. The mounting block is equipped with a positioning shaft, which is inserted into the positioning through holes. A screw is inserted into the axial position of the pressure cap and threadedly connected to the mounting block.

[0012] The connector is a screw, and the opening has at least one screw mounting hole that spans both ends of the opening.

[0013] Compared with the prior art, the clamping fixture for the outer diameter of a machine tool disclosed in this application has a simple installation and positioning method. The parts are installed sequentially on the outside of the mounting block and then clamped with an outer clamping ring. The pressure cap is used to press and position the parts between the mounting block and the pressure cap. This allows for the simultaneous processing of the outer arc surfaces of multiple parts, improving the processing efficiency and ensuring the stability of the processing quality. After processing, the parts can be easily disassembled and removed. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0022] Specific Implementation Example 1: Please refer to Figures 1 to 7In this embodiment of the invention, a clamping fixture for machining the outer diameter of a machine tool can simultaneously machine the outer end face of the main board 901 of part 9 and the outer end face of the connecting plate 902. The structure of this application includes a positioning base 1, which includes a clamping end 2 and a support platform 3. When using this fixture, the clamping end 2 on the positioning base 1 is clamped by a three-jaw chuck of a lathe to achieve a fixed connection with the machine tool. The clamping end 2 is fixed to the left side of the support platform 3. Both the clamping end 2 and the support platform 3 are cylindrical structures and are coaxially arranged. In this embodiment, the outer diameter of the clamping end 2 is smaller than the outer diameter of the support platform 3. The support platform 3 includes a mounting block 301. A slot 302 is provided around the outer side of the mounting block 301 along its outer wall, near the clamping end 2. The opening 501 of the slot 302 faces away from the clamping end. The mounting block 301 is horizontally positioned, and a pressure cover 4 is detachably mounted on the right side of the mounting block 301, which abuts against the mounting block 301. The pressure cover 4 has a disc structure and is coaxially mounted with the mounting block 301. The mounting block 301 has a hollow structure, and the pressure cover 4 and the mounting block 301 are fixedly connected by screws 8. The pressure cover 4 has several positioning through holes 402 equidistantly arranged along the axial direction. In this embodiment, the pressure cover 4 has four positioning through holes 402. A positioning shaft 7 is mounted on the mounting block 301 and is inserted into the positioning through holes 402. A screw 8 is inserted into the axial position of the pressure cover 4 and threadedly connected to the mounting block 301. By setting the positioning shaft 7, it is ensured that the pressure cover 4 and the mounting block 301 can achieve precise positioning and installation, and that the force between the pressure cover 4 and the mounting block 301 is uniform, so as to achieve stable positioning and clamping of the part 9.

[0023] The pressure cap 4 has a storage slot 401. Parts 9 are sequentially assembled side by side along the outer side of the mounting block 301 between the slot 302 and the storage slot 401. Positioning plates 903 on parts 9 are inserted into the slot 302 and the storage slot 401 respectively. One end of the positioning plate 903 of part 9 is inserted into the slot 302, and the other end of the positioning plate 903 abuts against the inner wall of the storage slot 401. The width W2 of the slot 302 gradually decreases towards the clamping end 2. The side of the storage slot 401... The wall thickness H1 gradually increases towards the bottom of the storage slot 401, meaning that the side walls where the slot 302 and the storage slot 401 are located are both inclined structures. This inclined structure can clamp the positioning plate 903 that abuts against it, clamping the positioning plate 903 between the storage slot 401 and the mounting block 301. The positioning plate 903 is fully inserted into the slot 302 and the storage slot 401, so that the part 9 can be more securely fixed to this device, avoiding the part 9 from shaking during subsequent processing and affecting the processing quality.

[0024] The plane of the outer circular sidewall of the pressure cap 4 is lower than the plane of the main board 901 of the part 9, which can prevent the diameter of the pressure cap 4 from being too large and thus hindering the cutting tool from machining the end face of the main board 901.

[0025] This application also includes an outer clamping ring 5, which is a circular ring structure. The part 9 is clamped inside the outer clamping ring 5. The outer clamping ring 5 is coaxially arranged with the support platform 3. The outer clamping ring 5 has an opening 501, and a connector 6 is provided at the opening 501 to connect and fix the two ends of the opening 501. In this embodiment, the connector 6 is a screw, and a screw mounting hole 502 is provided at the opening 501, which spans across the two ends of the opening 501. By setting the outer clamping ring 5, multiple parts 9 clamped on the mounting block 301 can be uniformly clamped and positioned, and the parts 9 can be further secured to the positioning base 1, avoiding displacement and other defects during processing that would affect the overall processing efficiency and quality of the product.

[0026] In this embodiment, the width W1 of the outer clamping ring 5 is less than the length of the main board 901 on the part 9. After the outer circle of the exposed main board 901 is processed, the outer clamping ring 5 can be loosened, slid to the opposite direction and then the opening 501 can be locked to continue processing the unprocessed outer circle on the main board 901 of the part 9. The whole disassembly and assembly process is simple and fast.

[0027] Compared with the prior art, the clamping fixture for the outer diameter of a machine tool disclosed in this application has a simple installation and positioning method. The parts are installed sequentially on the outside of the mounting block and then clamped with an outer clamping ring. The pressure cap is used to press and position the parts between the mounting block and the pressure cap. This allows for the simultaneous processing of the outer arc surfaces of multiple parts, improving the processing efficiency and ensuring the stability of the processing quality. After processing, the parts can be easily disassembled and removed.

[0028] It will be apparent to those skilled in the art that the present invention is not limited to the details of the foregoing exemplary embodiments, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention.
