Description

Technical Field

[0001] The utility model relates to the technical field of precision hardware processing, in particular to a CNC tapping tooling for a compression nut. Background Technique

[0002] In the prior art, the tooling fixtures used for CNC tapping of compression nuts are prone to operation errors. Since the tooling fixtures need to be manually operated, the hand movements of the operators are easily affected by the environment, resulting in problems such as incomplete clamping and unstable clamping of the fixtures. Such operation errors may directly affect the processing accuracy and production efficiency. The existing tooling fixtures have a short service life. Since the tooling fixtures need to be frequently mechanically operated, problems such as wear, deformation, and fracture of the fixtures are very common. This not only increases the loss of the fixtures, but also may lead to a short service life of the fixtures, requiring frequent replacement and increasing the production cost. For this reason, a CNC tapping tooling for a compression nut is proposed. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the existing defects and provide a CNC tapping tooling for a compression nut. The pneumatic reaction speed is fast, which can shorten the auxiliary time during the production process and improve the production efficiency. The components in the pneumatic fixture are all standard parts, which are easy to purchase and assemble, reducing the maintenance cost. The pneumatic fixture can change the clamping method and clamping range through combination, modification, etc. to adapt to the processing requirements of different workpieces. The design of the pneumatic fixture attaches importance to the safety mechanism and has a function of air cut-off protection to ensure that when air cut-off or air leakage occurs at any position, the fixture will not release the workpiece and can last for a certain period, which can effectively solve the problems in the background technique.

[0004] To achieve the above purpose, the utility model provides the following technical scheme: A CNC tapping tooling for a compression nut, including an M8*40 hexagon socket head cap screw, a slider, a cylinder adjusting washer, a cylinder body, an M6*70 hexagon socket head cap screw and a tapping tooling main body. Four installation grooves are opened at the upper end of the tapping tooling main body, and a slider slides in the middle of the upper end of each installation groove. Four cylinder adjusting washers are placed at the four corners of the upper end of each cylinder body. Each M6*70 hexagon socket head cap screw passes through a corner of the cylinder body and a cylinder adjusting washer and is threadedly connected to the tapping tooling main body. The M8*40 hexagon socket head cap screw passes through the middle of the tapping tooling main body and is threadedly connected to the middle of the slider and the piston of the cylinder body respectively.

[0005] Compressed air enters from the air pipe joint, enters the cylinder body through the air path, and pushes the cylinder piston to move downward. During the downward movement of the wedge-shaped slider connected to the cylinder piston, the wedge-shaped clamping block cooperating with the wedge-shaped slider is squeezed and slides in the direction normal to the movement direction of the wedge-shaped slider, thereby completing the axial positioning process of the "compression nut".

[0006] Further, it also includes clamping blocks, compression nuts, M12*35 hexagon socket head cap screws, tooling flanges, tooling clamping bases and M8*25 hexagon socket head cap screws. There are four cylinder bodies. One clamping block is placed on each of the front and rear sides of each slider at the upper end of the tapping tooling body. One compression nut is placed on one side of each clamping block at the upper end of the tapping tooling body. The front and rear ends of the tapping tooling body are fixedly connected to two tooling flanges through five M8*25 hexagon socket head cap screws respectively. The left and right sides at the lower end of the tapping tooling body are fixedly connected to the tooling clamping base through two M12*35 hexagon socket head cap screws respectively. When the manipulator grabs the "compression nut" workpiece and moves it to the reserved position for profiling machining, the radial positioning process of the "compression nut" is completed. A chip removal waist-shaped hole for preventing blockage of the clamping position by iron chips, cutting fluid, etc. is reserved between the wedge-shaped slider, the wedge-shaped clamping block and the clamping surface of the "compression nut".
