Description

Technical Field

[0001] The present invention relates to the technical field of metal processing positioning, and more specifically to a drilling positioning device for a turbine shell of a turbocharger. Background Art

[0002] The drilling and positioning device of the turbine shell of the turbocharger can ensure that the required holes are accurately punched on the turbine shell, which is crucial to the performance and reliability of the turbocharger. The precise drilling and positioning device on the machine tool can avoid assembly problems or performance degradation caused by hole position deviation. Secondly, the processing efficiency can be improved. The use of the drilling and positioning device can significantly reduce the time for manual hole adjustment and improve the processing efficiency.

[0003] After searching the existing published documents, the Chinese patent announcement number CN219853344U discloses a drilling positioning clamping device for the production of turbocharger turbine shells. The device is movably connected to a clamping plate through the outer side of the bottom of the connecting rod. The central part of the drilling positioning device for the production of turbocharger turbine shells is provided with a positioning shaft, and the turbine shell is effectively fixed after being installed on the rotating disk. In this way, when drilling, after a single mounting hole is processed, the stepper motor controls the rotating disk to rotate 90° so that the adjacent processing holes are located at the bottom of the drill bit, thereby reducing the turbine shell clamping adjustment steps, improving the hole processing accuracy, and effectively improving the drilling efficiency. However, the device has the following problems.

[0004] The drilling positioning device can position the turbocharger turbine shell, and after positioning, drilling is performed through a machine tool. Although the turbocharger turbine shell is positioned and fixed during the drilling process, since multiple holes need to be drilled on the turbocharger turbine shell after positioning, when the drill bit contacts the turbocharger turbine shell for drilling, once the drill bit is offset, this will cause the drilling position of the turbocharger turbine shell to be incorrect, making it difficult to accurately guide and position the drilling of multiple holes on the turbocharger turbine shell according to the specified lateral spacing, and it is difficult to accurately guide and position the drilling of multiple holes on the turbocharger turbine shell according to the specified longitudinal spacing. In this way, the drilling positioning accuracy of the turbocharger turbine shell is poor, which greatly reduces the pass rate of the turbocharger turbine shell drilling positioning.

[0033] In this embodiment, as shown in the attached Figure 8-9 As shown, the vertical synchronous positioning assembly includes a linkage electric cylinder 29 fixedly arranged at the bottom end of the ring frame 1; a mounting plate 30 is fixedly installed on one side of the linkage electric cylinder 29, and a plurality of positioning blocks 31 are fixedly connected to the upper surface of the mounting plate 30, and a plurality of positioning inner strips 32 are arranged in the gap surrounded by the plurality of positioning blocks 31, and the plurality of positioning inner strips 32 are fixedly connected to the mounting plate 30; a supercharger turbine shell 33 is inserted at the top of the positioning block 31, and the plurality of positioning inner strips 32 are inserted into the supercharger turbine shell 33, and a positioning pressure column 34 is arranged on the upper surface of the supercharger turbine shell 33, and a linkage frame 35 is installed on one side of the outer wall of the positioning pressure column 34, and the positioning pressure column 34 and the ring frame 1 are fixedly connected to the linkage frame 35. There is a gap between two adjacent positioning inner strips 32, and the plurality of positioning inner strips 32 are arranged in a circular ring with equal spacing; a controller 36 is fixedly connected to the other side of the linkage electric cylinder 29.

[0034] The operating principle of the turbocharger turbine shell drilling and positioning device of the present invention is as follows:

[0035] Step 1: When positioning vertically and synchronously, first use bolts to insert into the holes of the mounting plate 30, and then fix the mounting plate 30 on the processing platform of the machine tool. The supercharger turbine shell 33 is inserted into the top of multiple positioning blocks 31 to place the workpiece of the supercharger turbine shell 33. At the same time, the supercharger turbine shell 33 is inserted into the gaps adjacent to multiple positioning inner strips 32, and the mounting plate 30 supports multiple positioning blocks 31, and the mounting plate 30 supports multiple positioning inner strips 32, so that the supercharger turbine shell 33 is positioned and plugged. At the same time, the mounting plate 30 supports the linkage electric cylinder 29, and the controller 36 starts the linkage electric cylinder 29 to drive the ring frame 1 to move downward, and the ring frame 1 drives the linkage frame 35 to move downward. The linkage frame 35 can drive the positioning pressure column 34 to move downward, and the positioning pressure column 34 is squeezed on the upper surface of the supercharger turbine shell 33 to position and fix the upper surface of the supercharger turbine shell 33. At the same time, the supercharger turbine shell 33 can be vertically positioned at multiple points at the bottom to ensure that the supercharger turbine shell 33 can be vertically positioned. After positioning, the linkage electric cylinder 29 is closed by the controller 36.

[0036] Step 2, during synchronous lateral spacing positioning, set the lateral positioning spacing distance of the punching in the controller 36, so that the controller 36 starts the reduction motor 6, the reduction motor 6 drives the screw 17 to rotate, the screw 17 drives the sleeve block 3 to move downward under the action of the thread transmission force, the sleeve block 3 moves downward along the inner wall of the slide frame 2, the sleeve block 3 drives the groove ring 4 to move downward, the groove ring 4 makes multiple connecting shafts 5 move downward synchronously, the connecting shaft 5 drives the top end of the sleeve rod 7 to move downward, and the sleeve rod 7 drives the linkage shaft 8 to move right, and the linkage shaft 8 drives the groove plate 9 to move right.

[0037] At the same time, the groove plate 9 slides rightward along the inner wall of the sliding sleeve block 16, and the groove plate 9 can drive the V-shaped guide groove plate 10 to move rightward, and the V-shaped guide groove plate 10 drives the two slide shafts 11 to approach along the V-shaped path, and the distance between the two slide shafts 11 becomes smaller. At the same time, the two adjacent transverse positioning guide plates 12 approach each other, and the two transverse positioning guide plates 12 slide along the outer wall of the concave column 15 at the same time. The transverse positioning guide plate 12 drives the induction block 13 to approach the transverse distance sensor 14, and the transverse distance sensor 14 senses the distance between the transverse distance sensor 14 and the induction block 13. When the distance sensed by the transverse distance sensor 14 is the same as the transverse positioning interval distance of the punching set by the controller 36, the reduction motor 6 is turned off by the controller 36, and multiple punching positions on the supercharger turbine shell 33 can be synchronously transversely spaced and positioned according to the specified distance.

[0038] Step 3: During synchronous longitudinal spacing positioning, the longitudinal positioning spacing distance of the punching is set on the controller 36, so that the downward moving electric cylinder 18 is started through the controller 36, and the downward moving electric cylinder 18 pushes the groove ring 19 downward, and the groove ring 19 drives multiple pressing shafts 20 to move downward synchronously, and the pressing shaft 20 drives the top of the shaft sleeve rod 21 to move downward, and the shaft sleeve rod 21 drives the push shaft 22 to move left at the same time, and the push shaft 22 drives the concave block 23 to move left. The concave block 23 causes the longitudinal positioning sleeve plate 24 to move left, and the longitudinal positioning sleeve plate 24 slides left along the outer wall of the sliding bar 26, and at the same time the ring frame 1 supports the sliding bar 26, and the sliding bar 26 supports the fixed positioning guide plate 25, so that the longitudinal positioning sleeve plate 24 moves close to the fixed positioning guide plate 25.

[0039] At the same time, the longitudinal positioning sleeve 24 can drive the longitudinal distance sensor 28 to move leftward, and the longitudinal distance sensor 28 moves leftward toward the longitudinal sensing strip 27. The longitudinal distance sensor 28 senses the distance between the longitudinal distance sensor 28 and the longitudinal sensing strip 27. If the distance value sensed by the longitudinal distance sensor 28 is the same as the longitudinal positioning interval distance set on the controller 36, the controller 36 closes the lowering electric cylinder 18, and multiple punching positions on the supercharger turbine housing 33 can be synchronously longitudinally spaced and positioned according to the specified distance.

[0040] Step 4: When drilling holes in the supercharger turbine shell 33, the machine tool drill is inserted into the gap between the two fixed positioning guide plates 25 and moves downward along the gap between the two fixed positioning guide plates 25. At the same time, the machine tool drill enters the gap between the two transverse positioning guide plates 12 and contacts the drilling position on the upper surface of the supercharger turbine shell 33. In this way, the machine tool drill can accurately drill holes on the supercharger turbine shell 33 according to the specified transverse positioning position and the specified longitudinal positioning position when drilling holes, greatly improving the drilling positioning accuracy of the turbocharger turbine shell, and greatly improving the drilling positioning qualification rate of the turbocharger turbine shell.
