Technical Field

[0001] The utility model relates to the technical field of clamping tooling structures, in particular to a processing fixture for a notched copper oil ring-shaped part. Background Technique

[0002] The notched copper oil ring-shaped part mainly consists of an external ring-shaped main body and a notch at the bottom, and is mainly used as a sealing part or an oil guiding part in an oil circuit system.

[0003] When processing the oil ring shape, it is not easy to clamp, and it is limited by the notch opening direction. Once it is installed reversely, it is easy to cause scrapping. In addition, during the processing, the tool generates stress, and the clamping external force will cause the part to deform and vibrate the tool. After deformation, the size cannot be guaranteed, and it cannot be remedied by auxiliary methods such as shaping, resulting in scrapping and increased manufacturing costs.

[0004] In order to solve the above problems, a processing fixture for a notched copper oil ring-shaped part is provided to solve the problems of inconvenient part fixation, ensure the requirements of the outer circle and end face runout of such parts to be processed, and low processing efficiency.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] Referring to Figure 1 and Figure 2 , a processing fixture for a notched copper oil ring part disclosed by the present invention includes a fixed disk 1. A placing groove 11 is provided in the middle of the fixed disk 1. A clamping and fixing assembly 2 is arranged inside the fixed disk 1. The clamping and fixing assembly 2 includes a fixing part 21 and an adjusting part 22. The fixing part 21 is located in the middle of the placing groove 11, and the adjusting part 22 is located outside the placing groove 11. When processing, after placing the workpiece inside the placing groove 11, the position of the workpiece is adjusted through the adjusting part 22, and then it is reinforced through the fixing part 21, and then processing is carried out to ensure the quality and efficiency of processing.

[0028] A threaded hole 12 is provided in the middle of the placing groove 11. The fixing part 21 includes a screw rod 211 and a pressing plate 212. One end of the screw rod 211 is threadedly connected to the threaded hole 12, and the other end is fixedly connected to the pressing plate 212. Under the rotation of the screw rod 211, the pressing plate 212 is pressed against the surface of the workpiece for locking and fixing, and it is convenient to take out after processing is completed.

[0029] A rubber layer 213 is provided on the side of the pressing plate 212 facing the fixed disk 1. On the one hand, the rubber layer 213 can improve the friction with the workpiece and improve the connection stability. On the other hand, it can prevent the pressing plate 212 from directly contacting the workpiece and avoid scratching the surface of the workpiece.

[0030] An installation groove 13 is provided inside the fixed disk 1. The adjusting part 22 is located inside the installation groove 13. The adjusting part 22 includes a return spring 221, a connecting rod 222 and a locking head 223. The return spring 221 is installed inside the installation groove 13. One end of the return spring 221 is connected to the connecting rod 222. The end of the connecting rod 222 away from the return spring 221 is connected to the locking head 223. When the workpiece is placed inside the placement groove 11, the workpiece pushes the locking head 223 and the connecting rod 222 to retract. At this time, the return spring 221 is in a compressed state. Then when the workpiece is taken out, the return spring 221 rebounds and drives the connecting rod 222 and the locking head 223 to reset, facilitating the fixation of the workpiece.

[0031] A guiding part 224 is arranged inside the installation groove 13. The connecting rod 222 is located inside the guiding part 224. The guiding part 224 is used to ensure the stability of the connecting rod 222 during the moving process and prevent the position from shifting.

[0032] A stop anti-reverse pin 3 is arranged inside the placement groove 11. The stop anti-reverse pin 3 can effectively prevent the workpiece from being installed reversely and achieve an anti-fooling effect.

[0033] During installation, the fixed disk 1 is installed on the machine tool connection chuck. Then the stop anti-reverse pin 3 is inserted into the placement groove 11 of the fixed disk 1. When the workpiece is inserted into the placement groove 11, the adjusting rod and the locking head 223 are driven by the return springs 221 on both sides to be locked and fixed. Then the pressing plate 212 is fixed by driving the threaded rod. After processing the product of this process, only the pressing plate 212 and the threaded rod need to be removed.

[0034] This fixture adopts overall contact with non-machined surfaces, reduces the deformation caused by cutting force, enables quick line change, and is convenient and fast.
