Technical Field

[0001] This utility model relates to the field of turbocharger body machining technology, specifically to a fixture for machining turbocharger bodies on a CNC lathe. Background Technology

[0002] In the overall structure of a turbocharger, the middle body is the core load-bearing structure connecting the turbine end and the compressor end. To improve machining accuracy, it is processed using a CNC lathe. Before machining, the middle body also needs to be stably clamped using relevant fixtures. For example, CN219234403U discloses a clamping and fixing device for welding the middle body of a turbocharger. During operation, the clamping and fixing device uses a hydraulic cylinder to control the support arc plate to move upward under the support of two guide slide rods, while the height of the other support arc plate remains unchanged. During the process of the support arc plate driving the turbocharger middle body fixture to move upward, the turbocharger middle body fixture is supported by two support rollers contacting the support arc plate.

[0003] However, the aforementioned clamping and fixing device only supports the middle body of the booster, and the middle body cannot be effectively squeezed and positioned in the longitudinal position, which makes it easy for it to shake during the processing and reduce the processing accuracy.

A fixing ring 11 is fixedly provided on the side of the support cylinder 3. A positioning rod 12 is slidably passed through the inside of the rotating block 9. A plurality of positioning grooves 13 are provided on the side of the fixing ring 11 near the rotating block 9, arranged symmetrically around it. The end of the positioning rod 12 is inserted into the positioning groove 13. A spring 14 is sleeved on the rod wall of the positioning rod 12. The two ends of the spring 14 are fixedly connected to the rotating block 9 and the positioning rod 12 respectively.

[0021] To ensure that the angle of the clamped body can be adjusted according to processing requirements after it is fixed in place, such as... Figure 1 and Figure 4 As shown, a support box 16 is provided at the lower end of the support plate 1. A support column 17 is rotatably provided at the bottom of the inner wall of the support box 16. The support column 17 is fixedly connected to the support plate 1. Two symmetrically arranged semi-circular cover plates 24 are screwed to the top of the support box 16. A rotating groove is opened on the side of the semi-circular cover plate 24 to cooperate with the rotation of the support column 17. A first spur gear 18 is fixedly provided at the lower end of the outer wall of the support column 17. A motor 19 is fixedly provided on the outer wall of the support box 16. The end of the output shaft of the motor 19 passes through the support box 16 and is fixedly provided with a first bevel gear 20.

A second spur gear 22 and a second bevel gear 23 are fixedly sleeved on the rod wall of the transmission rod 21. The second spur gear 22 is configured to cooperate with the first spur gear 18, and the first bevel gear 20 is configured to cooperate with the second bevel gear 23.

[0022] Working principle: First, the turbocharger body to be processed is placed on the arc-shaped support plate 1. The arc structure can better fit the outer wall of the body, initially limiting the lateral displacement of the body. Then, the longitudinal strap 4 is pulled close to one end of the support cylinder 3, so that the longitudinal strap 4 slides along the connecting ring 2 and passes through the perforations 5 opened at the upper and lower ends of the support cylinder 3, covering the top of the turbocharger body. At this time, the baffle 15 fixed on the inner wall of the support cylinder 3 contacts the longitudinal strap 4, which can prevent the longitudinal strap 4 from shifting inside the support cylinder 3 and ensure the stability of the pressing direction. After the longitudinal strap 4 presses the middle body longitudinally to a suitable degree, the positioning rod 12, which slides through the rotating block 9, is pulled. The positioning rod 12 compresses the spring 14 sleeved on its rod wall, causing the end of the positioning rod 12 to disengage from the positioning groove 13 on the fixing ring 11, thus releasing the limitation on the rotating block 9. Then, the rotating block 9 is rotated, and the rotating block 9 drives the rotating rod 6, which is fixedly connected to it, to rotate in the rotating hole on the side of the support cylinder 3. The rotating rod 6 drives the rotating plate 7, which is fixedly sleeved on the rod wall, to rotate synchronously. Multiple limiting claws 8 fixed on the outer wall of the rotating plate 7 rotate with the rotating plate 7 until the limiting claws... The 8 is interference-fitted with the outer wall of the longitudinal strap 4. The position of the longitudinal strap 4 is fixed by the clamping action of the limiting claw 8, and the longitudinal pressing and positioning of the middle body of the booster is completed. At the same time, as the rotating plate 7 rotates, the multiple limiting claws 8 can continue to rotate and squeeze and drive the longitudinal strap 4 to stretch, improving the pressing effect of the longitudinal strap 4 on the middle body. Then the positioning rod 12 is released, the spring 14 returns to its original position and pushes the end of the positioning rod 12 into the positioning groove 13 of the corresponding position of the fixing ring 11, fixing the angle of the rotating block 9 and preventing the limiting claw 8 from loosening and causing the longitudinal strap 4 to shift. If the angle of the middle body needs to be adjusted during processing, the motor 19 fixed on the outer wall of the support box 16 is started. The output shaft of the motor 19 drives the first bevel gear 20 fixed at its end to rotate. The first bevel gear 20 drives the mating second bevel gear 23 to rotate. The second bevel gear 23 drives the transmission rod 21 fixedly connected to it to rotate at the bottom of the inner wall of the support box 16. The transmission rod 21 drives the second spur gear 22 fixedly sleeved on the rod wall to rotate. The second spur gear 22 drives the mating first spur gear 18 to rotate. The first spur gear 18 drives the support column 1 fixedly connected to it to rotate. 7. Rotation: The support column 17 drives the top fixed support plate 1 to rotate synchronously. The support plate 1 drives the positioned booster body to adjust its angle. The rotation grooves on the sides of the two semi-circular cover plates 24 screwed to the top of the support box 16 provide guidance for the rotation of the support column 17, ensuring the stability of the angle adjustment process. Until the body rotates to the required processing angle, the motor 19 can be turned off to carry out subsequent processing operations. In addition, the limiting bar 10 fixedly provided at one end of the longitudinal strap 4 near the connecting ring 2 can prevent the longitudinal strap 4 from falling out of the connecting ring 2 when it is pulled, ensuring the continuity of operation.
