Description

Technical Field

[0001] This utility model relates to the field of turbine housing processing technology, and more specifically, to a positioning processing device for turbine housing blanks. Background Technology

[0002] The turbine housing is a key component of a turbocharger, its function being to guide the flow of exhaust gas and drive the turbine to rotate. Turbocharging technology is widely used in the automotive, marine, and industrial fields to improve engine intake efficiency. As the core component of a turbocharger, the turbine housing has a complex structure and requires extremely high machining precision. The positioning and machining of the turbine housing blank is a crucial step in determining the quality of the final product.

[0003] Existing positioning and processing devices mostly adopt fixed clamping structures, and the shape of the clamping plate is used for positioning. It is impossible to adjust the clamping surface according to whether the raw material is laid flat or upright. The only solution is to replace the positioning and processing device. Moreover, the existing positioning and processing devices can only realize the positioning and clamping function and cannot assist in flattening the top of the raw material held upright, resulting in low efficiency. Therefore, a positioning and processing device for turbine housing blanks is proposed. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a positioning and processing device for turbine housing blanks to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a positioning and processing device for turbine housing blanks, comprising a worktable, a first turntable being provided on the top of the worktable, a first motor being connected to the bottom of the first turntable, starting the first motor to control the rotation of the first turntable, which can drive the raw material on the top of the first turntable to rotate and adjust the processing position, symmetrically opening limit grooves on both sides of the top of the first turntable, a limit slider being provided in the middle of the limit groove, a first threaded rod being inserted in the middle of the limit slider, one end of the first threaded rod being connected to a second turntable, rotating the second turntable to control the first threaded rod to drive the limit slider to slide inside the limit groove, which facilitates the top clamping block to clamp the raw material;

[0006] The top of the limiting slider is provided with a clamping block, a protective plate is fixedly connected to one side of the clamping block, a positioning rod is fixedly connected to the bottom of the clamping block, and a positioning slot is opened on the top of the limiting slider. By pulling out and flipping the clamping block, and inserting the positioning rod into the positioning slot, the protective plate is positioned on the opposite side of the two clamping blocks.

[0007] The first turntable has limit grooves on both sides of its top. A movable plate is provided in the middle of the limit groove. A spreading shaft is fixedly connected to the top of the movable plate. A second threaded rod is inserted in the middle of the movable plate. One end of the second threaded rod is connected to a third turntable. A flattening mechanism is provided on one side of the top of the worktable. Rotating the third turntable can control the second threaded rod to move the movable plate, thereby controlling the spreading shaft to spread and position the raw material in the middle, achieving the positioning effect. The flattening mechanism can flatten the top plane during positioning, improving the positioning and fixing effect.

[0008] Preferably, the first motor is fixed in the middle of the worktable, the threads at both ends of the first threaded rod are symmetrical, the first threaded rod passes through the limiting slider and is threadedly connected to the limiting slider, and the first motor is started to control the rotation of the first turntable, which facilitates the rotation of the top raw material.

[0009] Preferably, the side wall of the clamping block away from the protective plate is set with an arc-shaped structure, the positioning rod is adapted to the positioning slot, and the positioning rod is set in the middle of the positioning slot. The arc shape of one side of the clamping block can clamp the side of the flat raw material, and the orientation of the clamping block can be reversed to clamp and fix the upright raw material.

[0010] Preferably, a stabilizing rod is inserted into the middle of the moving plate, and the second threaded rod is symmetrically threaded in the middle part of the two limiting grooves. The second threaded rod passes through the moving plate and is threadedly connected to the moving plate. The stability of the moving plate is improved by the stabilizing rod.

[0011] Preferably, the flattening mechanism includes a support frame disposed on one side of the top of the workbench, a connecting plate fixedly connected to the bottom of the support frame, the connecting plate passing through the workbench and extending to the middle of the workbench, and the cross-sectional shape of the connecting plate being set as "T".

[0012] Preferably, the cross-sectional shape of the support frame is set as "U" shape, a pressure plate is provided on one side of the support frame, a bonding plate is fixedly connected to the bottom of the pressure plate, and a third threaded rod and a stabilizing rod are inserted into one end of the pressure plate.

[0013] Preferably, the stabilizing rod is fixed in the middle of the support frame, the third threaded rod is threadedly connected to the pressure plate, and a second motor is provided at the top of the third threaded rod extending to the top of the support frame. Activating the second motor controls the third threaded rod to move the pressure plate downwards. This allows for the compression of the side flange of the raw material when it is placed upright, ensuring the side flange is horizontal at the bottom of the pressure plate. The stabilizing rod improves the stability of the pressure plate's movement. The connecting plate allows the support frame to rotate after the pressure plate is assisted in its fixation, enabling the pressure plate to be moved away from the top of the raw material for convenient processing and use.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. This utility model first controls the first threaded rod to drive the limiting slider to slide inside the limiting groove by rotating the second turntable, which facilitates the top clamping block to clamp the raw material and makes it easy to clamp and fix the flat raw material. By pulling out and flipping the clamping block and inserting the positioning rod into the positioning slot, the protective plate is located on the opposite side of the two clamping blocks, which facilitates the flat clamping and fixing of the raw material when it is placed upright. It is convenient to adjust and use flexibly. Moreover, the flattening mechanism can help flatten the top surface when it is placed upright, improve the positioning and fixing effect, and facilitate processing and use.

[0016] 2. This utility model can also control the second threaded rod to move the moving plate by rotating the third turntable, thereby controlling the opening shaft to open and position the raw material in the middle to achieve the positioning effect. By starting the first motor to control the rotation of the first turntable, the raw material on the top of the first turntable can be rotated to adjust the processing position, which is convenient for processing the raw material in different positions. The stabilizing rod can improve the stability of the lifting of the pressure plate, and the connecting plate can adjust and move the position of the pressure plate to improve the use effect.

[0017] In summary, through the interaction of the above-mentioned functions, it is possible to clamp and fix the raw materials both horizontally and vertically. At the same time, when the raw materials are placed vertically, the top surface can be flattened to improve the positioning and fixing effect, so that they can be used for subsequent processing.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] As attached Figure 1-5 The device shown is a positioning and processing device for turbine housing blanks, including a worktable 1. A first turntable 2 is provided on the top of the worktable 1. A first motor 3 is connected to the bottom of the first turntable 2. Starting the first motor 3 controls the rotation of the first turntable 2, which can drive the raw material on the top of the first turntable 2 to rotate and adjust the processing position. Limiting grooves 4 are symmetrically opened on both sides of the top of the first turntable 2. A limiting slider 5 is provided in the middle of the limiting groove 4. A first threaded rod 6 is inserted in the middle of the limiting slider 5. One end of the first threaded rod 6 is connected to a second turntable 7. Rotating the second turntable 7 controls the first threaded rod 6 to drive the limiting slider 5 to slide inside the limiting groove 4, which facilitates the top clamping block 8 to clamp the raw material.

[0026] The top of the limiting slider 5 is provided with a clamping block 8, a protective plate 11 is fixedly connected to one side of the clamping block 8, a positioning rod 9 is fixedly connected to the bottom of the clamping block 8, and a positioning slot 10 is opened on the top of the limiting slider 5. By pulling out and flipping the clamping block 8, and inserting the positioning rod 9 into the positioning slot 10, the protective plate 11 is located on the opposite side of the two clamping blocks 8.

[0027] The first turntable 2 has limit grooves 12 on both sides of its top. A movable plate 13 is provided in the middle of the limit groove 12. A supporting shaft 16 is fixedly connected to the top of the movable plate 13. A second threaded rod 14 is inserted in the middle of the movable plate 13. One end of the second threaded rod 14 is connected to a third turntable 15. A flattening mechanism is provided on one side of the top of the worktable 1. Rotating the third turntable 15 can control the second threaded rod 14 to drive the movable plate 13 to move, thereby controlling the supporting shaft 16 to support and position the middle of the raw material, achieving the positioning effect. The flattening mechanism can flatten the top plane during positioning, improving the positioning and fixing effect.

[0028] As attached Figure 1-5As shown, the first motor 3 is fixed in the middle of the workbench 1. The threads at both ends of the first threaded rod 6 are symmetrical. The first threaded rod 6 passes through the limiting slider 5 and is threadedly connected to the limiting slider 5. The side wall of the clamping block 8 away from the protective plate 11 is set with an arc-shaped structure. The positioning rod 9 is adapted to the positioning slot 10. The positioning rod 9 is set in the middle of the positioning slot 10. A stabilizing rod is inserted in the middle of the moving plate 13. The second threaded rod 14 is symmetrically set with threads in the middle part of the two limiting slide grooves 12. The second threaded rod 14 passes through the moving plate 13 and is threadedly connected to the moving plate 13. The first motor 3 is started to control the first turntable 2 to rotate, which facilitates the rotation of the top raw material. The arc shape on one side of the clamping block 8 can clamp the side of the flat raw material. By adjusting the orientation of the clamping block 8, the upright raw material can be clamped and fixed. The stabilizing rod improves the stability of the moving plate 13.

[0029] As attached Figure 1-4 As shown, the flattening mechanism includes a support frame 17 disposed on one side of the top of the workbench 1. A connecting plate 18 is fixedly connected to the bottom of the support frame 17. The connecting plate 18 passes through the workbench 1 and extends to the middle of the workbench 1. The cross-sectional shape of the connecting plate 18 is "T" shaped, and the cross-sectional shape of the support frame 17 is "U" shaped. A pressure plate 19 is disposed on one side of the support frame 17. A bonding plate 20 is fixedly connected to the bottom of the pressure plate 19. A third threaded rod 21 and a stabilizing rod 22 are inserted into one end of the pressure plate 19. The stabilizing rod 22 is fixed in the middle of the support frame 17. The third threaded rod 21 is threadedly connected to the pressure plate 19. The top of the third threaded rod 21 extends to the top of the support frame 17 and is equipped with a second motor 23. When the second motor 23 is started, it controls the third threaded rod 21 to drive the pressure plate 19 to move downward. When the raw material is placed upright, it can squeeze the side flange of the raw material so that the side flange of the raw material is horizontal at the bottom of the pressure plate 19. The stability of the movement of the pressure plate 19 is improved by the stabilizing rod 22. After the pressure plate 19 is fixed by the connecting plate 18, the pressure plate 19 can drive the support frame 17 to rotate, so that the pressure plate 19 can be removed from the top of the raw material for convenient processing and use.

[0030] It is worth noting that in this application, an annular groove is provided axially on the inner wall of the threaded cylinder (threaded hole), and a nylon 66 damping ring with a Shore hardness of 85A is embedded in the groove. The continuous axial clamping force generated by its elastic deformation forms a helical angle interference fit with the surface of the threaded rod at 15°-20°. When the threaded pair is subjected to axial vibration load, the nylon insert can generate a maximum elastic compression of 0.3mm, which increases the friction coefficient between the thread contact surfaces from 0.15 to 0.68 (tested according to ASTM D1894 standard), effectively suppressing loosening displacement caused by thread springback.

[0031] The working principle of this utility model is as follows: When in use, the raw material is placed flat on the top of the first turntable 2, so that the opening shaft 16 is located in the hollow part of the raw material. The second turntable 7 is rotated to control the clamping block 8 to clamp the outside of the raw material, and the third turntable 15 is rotated to control the opening and clamping of the inside of the raw material, so as to achieve precise positioning of the raw material.

[0032] When the raw material is placed upright and needs to be processed at the side flange, the flange is placed directly above the raw material. First, move the pressure plate 19 so that the pressure plate 19 is at the top of the raw material. Then, start the second motor 23 to control the pressure plate 19 to drive the bonding plate 20 to squeeze the top of the raw material so that the top wall of the flange is at a horizontal level.

[0033] Then move the clamping block 8 upward to move the positioning rod 9 out of the positioning slot 10, flip the clamping block 8 so that the protective plate 11 is on the opposite side of the two clamping blocks 8, then rotate the second turntable 7 to control the clamping block 8 to clamp and fix the raw material, and start the second motor 23 to control the pressure plate 19 to reset, and rotate the pressure plate 19 to move away from the top of the raw material.

[0034] During processing, the first motor 3 can be started to control the first turntable 2 to drive the raw material to rotate slowly, thereby adjusting the processing position.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
