Description

Technical Field

[0001] This utility model relates to the field of CNC machining, specifically to an adjustable CNC machining tooling fixture. Background Technology

[0002] CNC (Computer Numerical Control) technology is a technology that uses digital computer programs to control machine tools and equipment for machining. It combines computer technology, automation control technology, and precision mechanical manufacturing technology, and is widely used in various manufacturing and processing processes. It features high precision, high efficiency, and high flexibility. When machining workpieces using CNC machine tools, tooling fixtures are required. However, common fixtures have relatively limited functionality. When drilling holes in different positions on a workpiece, the workpiece needs to be disassembled and reassembled multiple times. These multiple disassemblies and reassemblies during the workpiece machining process greatly reduce the machining efficiency. Therefore, this application proposes an adjustable CNC machining tooling fixture. Utility Model Content

[0003] In view of the problems existing in the existing adjustable CNC machining tooling fixtures, this utility model is proposed.

[0004] Therefore, the purpose of this utility model is to provide an adjustable CNC machining tooling fixture, which solves the problem that common CNC machine tool tooling fixtures are not convenient for adjusting the angle of the workpiece, thus making it impossible to complete drilling at different positions without removing the workpiece.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable CNC machining tooling fixture, including a base, with support plates fixedly installed at both ends of the top of the base, and openings on the top of the sides of the two support plates, with bearings fixedly installed in the two openings, and rotating shafts fixedly inserted into the two bearings, with a fixed plate and a clamping plate fixedly installed at the ends of the two rotating shafts that are close to each other, respectively, with a movable moving plate provided on the side of the fixed plate close to the clamping plate, and clamping grooves provided on the sides of the moving plate and the clamping plate that are close to each other, and a connecting block fixedly installed at the other end of the rotating shaft connected to the fixed plate, with limit grooves provided on the four side walls of the connecting block, and a first hydraulic rod fixedly installed on the outer side of the support plate close to the fixed plate, the telescopic end of the first hydraulic rod being able to be inserted into the limit groove on the side wall of the connecting block.

[0006] Preferably, a motor is fixedly installed on the outer side of another support plate, and the output end of the motor is fixedly connected to the rotating shaft of the side wall of the clamping plate.

[0007] Preferably, the inner walls of the side grooves of both the clamping plate and the movable plate are provided with anti-slip layers, and the positions of the side grooves of the clamping plate and the movable plate are at the same height.

[0008] Preferably, the limiting groove is set to a semi-circular groove shape, and the extension end of the first hydraulic rod is adapted to the shape of the limiting groove.

[0009] Preferably, two grooves are provided on the side of the movable plate near the fixed plate, and a second hydraulic rod is fixedly installed in each of the two grooves. The telescopic ends of the two second hydraulic rods are respectively fixedly connected to the two ends of the side of the movable plate.

[0010] Preferably, the maximum distance between the two clamping grooves on the side of the moving plate and the clamping plate is greater than the diameter of the clamping grooves.

[0011] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0012] By cooperating with the clamping plate and the moving plate, metal rods of different diameters can be fixedly clamped. During processing, the motor drives the clamping plate, the moving plate and the fixed plate to rotate. Then, the telescopic end of the first hydraulic rod engages with the limiting groove on one of the side walls of the connecting block, thereby positioning the workpiece after the angle has been adjusted. This eliminates the need to repeatedly disassemble and reassemble the workpiece when drilling holes in different positions, thus greatly improving the processing efficiency.

[0019] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0020] This utility model provides, for example Figure 1-3 An adjustable CNC machining fixture is shown, comprising a base 1, with support plates 2 fixedly mounted at both ends of the top of the base 1. Each support plate 2 has an opening 8 on its top side, and a bearing 9 is fixedly mounted within each opening 8. A rotating shaft 7 is fixedly inserted into each bearing 9. A fixed plate 3 and a clamping plate 5 are fixedly mounted at the ends of the two rotating shafts 7 that are close to each other. A movable sliding plate 4 is provided on the side of the fixed plate 3 near the clamping plate 5. A clamping groove 6 is provided on the side of the movable plate 4 and the clamping plate 5 that are close to each other. A connecting block 11 is fixedly mounted at the other end of the rotating shaft 7 connecting the fixed plate 3. Limiting grooves 13 are provided on the four side walls of the connecting block 11. A first... The first hydraulic rod 12 has its telescopic end inserted into the limiting groove 13 on the side wall of the connecting block 11. By controlling the second hydraulic rod 14, the moving plate 4 moves towards the position of the clamping plate 5. In this way, with the cooperation of the clamping plate 5 and the moving plate 4, the clamping grooves 6 on the sides of the clamping plate 5 and the moving plate 4 can fix and clamp metal rod workpieces of different diameters. When drilling at different positions of the workpiece, the motor 10 can drive the clamping plate 5, the moving plate 4 and the fixed plate 3 to rotate. Then, the telescopic end of the first hydraulic rod 12 engages with the limiting groove 13 on one of the side walls of the connecting block 11, thereby positioning the workpiece after the angle has been adjusted, and making the workpiece processing process more stable.

[0021] In order to rotate the clamped workpiece at an angle, such as Figure 1 As shown, a motor 10 is fixedly installed on the outer side of another support plate 2, and the output end of the motor 10 is fixedly connected to the rotating shaft 7 on the side wall of the clamping plate 5.

[0022] To increase the stability of the workpiece during clamping, such as Figure 1 As shown, anti-slip layers are provided on the inner walls of the clamping grooves 6 on the sides of the clamping plate 5 and the moving plate 4, and the clamping grooves 6 on the sides of the clamping plate 5 and the moving plate 4 are at the same height. The anti-slip layers on the inner walls of the clamping grooves 6 prevent the workpiece from slipping during clamping.

[0023] To fix the position of the workpiece after angle adjustment, such as Figure 1 and Figure 3 As shown, the limiting groove 13 is set in a semi-circular groove shape, and the telescopic end of the first hydraulic rod 12 is adapted to the shape of the limiting groove 13.

[0024] To adjust the position of the movable plate 4, such as Figure 1 and Figure 2As shown, two grooves are provided on the side of the movable plate 4 near the fixed plate 3. A second hydraulic rod 14 is fixedly installed in each of the two grooves. The telescopic ends of the two second hydraulic rods 14 are respectively fixedly connected to the two ends of the side of the movable plate 4. By controlling the second hydraulic rods 14, the movable plate 4 can be pushed closer to the position of the clamping plate 5, thereby changing the distance between the two and thus being able to clamp round rod-shaped workpieces of different diameters.

[0025] Finally, in order to place metal rods of different diameters, such as Figure 1 As shown, the maximum distance between the movable plate 4 and the two clamping grooves 6 on the side of the clamping plate 5 is greater than the diameter of the clamping grooves 6.

[0026] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
