Technical Field

[0001] This utility model relates to the field of turbocharger body runout detection technology, specifically to a turbocharger body end face runout detection and positioning fixture. Background Technology

[0002] The turbocharger body is the core load-bearing component connecting the turbine end and the compressor end, forming the turbocharger's skeleton. To ensure the stability of the turbocharger body during use, its manufacturing precision needs to be effectively controlled. Runout testing, as an indispensable part of precision testing, determines whether the turbocharger is stable enough during use. End face runout is an important component of various runout tests. However, common end face runout testing relies on fixed-specification positioning fixtures in conjunction with dial indicators. But because different types of turbocharger bodies have different specifications, fixed-specification positioning fixtures cannot be adapted to and stably clamp various turbocharger bodies, making it impossible to carry out the testing work normally.

[0003] Therefore, we propose a positioning fixture for detecting runout of the end face of the turbocharger body to solve the above problems. Utility Model Content

[0018] This utility model discloses a positioning fixture for detecting runout of the end face of a turbocharger.

[0019] This utility model provides, for example Figure 1-3 The present invention discloses a positioning fixture for detecting runout of the end face of a turbocharger body, comprising a detection base 1, a clamping part and a detection part on the top of the detection base 1, the clamping part including a support column 2 and a placement plate 3 fixedly mounted on the top of the support column 2, the placement plate 3 having a synchronous moving mechanism on the top, and multiple clamping plates 4 provided through the synchronous moving mechanism, the multiple clamping plates 4 being arc-shaped, each clamping plate 4 having an anti-slip block 19 on the side facing the turbocharger body, each anti-slip block 19 being a rubber anti-slip block, the synchronous moving mechanism including multiple drive screws 8, the placement plate 3 having a drive groove on the top, the multiple drive screws 8 being rotatably mounted in the drive groove, and each having a first bevel gear 9 fixedly mounted at one end close to each other, the multiple first bevel gears 9 being configured to cooperate, the drive screws 8 being threaded into the clamping plates 4, and a knob 10 fixedly mounted at the end of one drive screw 8, the drive screws 8 being configured to cooperate with the clamping plates 4, so that if one drive screw 8 rotates, it drives the other drive screws 8 to rotate, thereby driving the clamping plates 4 to move synchronously towards or away from the center.

[0020] The detection unit includes an adjusting screw 5. A groove is provided on the top of the detection base 1. The adjusting screw 5 is rotatably disposed in the groove, and a rotating block 6 is fixedly provided at its end. An adjusting mechanism is provided on the rod wall of the adjusting screw 5, and a dial indicator 7 is provided through the adjusting mechanism. The adjusting mechanism includes a moving plate 14, which is slidably disposed outside the adjusting screw 5. The two are threaded together, and a rotating groove is provided on its top. A damping rod 15 is rotatably disposed in the rotating groove. A swing plate 16 is fixedly provided on the rod wall of the damping rod 15. A damping sleeve 17 is fixedly passed through the end of the swing plate 16. A connecting rod 18 is rotatably disposed inside the damping sleeve 17. The connecting rod 18 is arranged in a ring shape and is fixedly connected to the dial indicator 7.

[0021] In order to enable the body to rotate slowly after it is stably clamped in the booster, such as Figure 1 and Figure 3 As shown, the top of the detection base 1 is provided with a rotating groove, the support column 2 is rotatably disposed in the rotating groove, and the outer wall is fixedly provided with a second bevel gear 11.

[0022] Working principle: When in use, place the booster body on the placement plate 3, turn the knob 10 to drive the drive screw 8 on one side to rotate. The first bevel gear 9 at the end of the drive screw 8 will drive the other first bevel gears 9 to rotate synchronously, thereby driving all drive screws 8 to rotate in the same direction. This causes the multiple clamping plates 4 threaded on the drive screw 8 to move synchronously towards the center. The arc-shaped clamping plates 4 are inserted and abutted against the positioning holes inside the booster body. The rubber anti-slip block 19 enhances the clamping stability and realizes the adaptation and fixation of booster bodies of different specifications. Then, rotating the rotating block 6 and adjusting the adjusting screw 5 will cause the moving plate 14 to slide along the groove to a suitable detection position. The damping rod 15 rotates in the rotating groove, the swing plate 16 swings around the damping rod 15, and the connecting rod 18 rotates in the damping sleeve 17 to adjust the detection angle and height of the dial indicator 7 so that the probe of the dial indicator 7 is in contact with the end face of the middle body. Start motor 12, the output shaft of motor 12 drives the third bevel gear 13 to rotate, the third bevel gear 13 meshes with the second bevel gear 11 to drive the support column 2 to rotate slowly in the rotating groove, thereby driving the booster body on the plate 3 to rotate synchronously. The dial indicator 7 detects the runout of each point on the end face of the body in real time to complete the accurate detection.
