Description

Technical Field

[0001] The invention relates to the technical field of mechanical processing fixtures, and in particular to a processing fixture for a turbocharger compression shell product for an automobile. Background Art

[0002] The compressor casing is an important boosting component on a turbocharger. During the manufacturing process of the existing compressor casing, a clamp is needed to fix the compressor casing to prevent it from moving during the processing. However, the existing compressor casing is often formed by casting. After casting, the workpiece needs to be fine-machined, and a clamp is often needed to clamp the workpiece and perform further processing.

[0003] Most existing machining fixtures clamp the workpiece through a three-turn chuck, which has a fast clamping speed, a simple structure, and is easy to operate.

[0004] However, since some compressor casings are not of regular shape, the workpiece will shake when the fixture rotates after being clamped. The uneven weight distribution will also increase the moment of inertia, increasing the resistance and imbalance during rotation. Summary of the invention

[0011] Furthermore, the movable sleeve is movably connected to the movable seat, and a spring-shaped guide groove is provided in the movable sleeve. The guide sleeve is slidably connected to the movable sleeve, and a guide column extending into the spring-shaped guide groove is provided on the guide sleeve.

[0012] Furthermore, an elastic member is provided in the movable sleeve, and two ends of the elastic member respectively abut against the movable seat and the guide sleeve, and a disc is provided at one end of the guide sleeve facing the workpiece.

[0013] Furthermore, a support rod is slidably mounted on the guide sleeve, and the support rod is semi-cylindrical, and the support rods on the two groups of guide sleeves cooperate with each other and form an integral columnar shape when fitted together.

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] The present invention will be further described below in conjunction with the embodiments.

[0034] A processing fixture for automotive turbocharger housing products, see attached Figure 1-7 , comprising a workbench 1, on which a driving member 11 is provided, and further comprising:

[0035] The correction component 2 includes two groups of movable seats 22 that can move away from and approach each other on the workbench 1 at the same time. The correction component 2 also includes a bidirectional screw 21. The bidirectional screw 21 is rotatably set on the workbench 1. The two groups of movable seats 22 are slidably set on the workbench 1 and are respectively located on both sides of the bidirectional screw 21. The movable seat 22 is threadedly connected with the bidirectional screw 21. A handle is provided on one side of the bidirectional screw 21. The two groups of movable seats 22 can move closer to and away from each other on the workbench 1 by rotating the bidirectional screw 21 with the handle. The two groups of movable seats 22 can move away from and approach each other on the workbench 1, wherein the two groups of movable seats 22 can move away from and approach each other only as an implementation method and are not limited to this structure. The two groups of movable seats 22 can also be moved away from and approached each other by two groups of synchronous cylinders. A movable sleeve 23 is provided on the movable seat 22, and a movable sleeve 23 is movably installed inside. The guide sleeve 24 is compressed and rotated. Specifically, the movable sleeve 23 is movably connected with the movable seat 22, and a spring-shaped guide groove 231 is provided in the movable sleeve 23. The guide sleeve 24 is slidably connected with the movable sleeve 23, and a guide column 241 extending into the spring-shaped guide groove 231 is provided on the guide sleeve 24. The spring-shaped guide groove 231 in the movable sleeve 23 is preferably provided with two groups, and two groups of guide columns 241 are correspondingly provided to improve the stability of the guide sleeve 24 when it is retracted and rotated. The two groups of movable seats 22 move synchronously to push the guide sleeve 24 to contact with the workpiece. After the contact, the guide sleeve 24 is compressed back into the movable sleeve 23, and when the guide column 241 on the guide sleeve 24 and the spring-shaped guide groove 231 on the movable sleeve 23 cooperate, the guide sleeve 24 rotates and drives the workpiece to rotate. A support rod 25 for supporting the workpiece is movably installed on the guide sleeve 24, and the support rod 25 is used to place the workpiece.

[0036] Specifically, an elastic member 26 is provided in the movable sleeve 23, and the two ends of the elastic member 26 respectively abut against the movable seat 22 and the guide sleeve 24. The elastic member 26 is used to always push the movable sleeve 23 and the guide sleeve 24 out. A disc is provided at one end of the guide sleeve 24 facing the workpiece. The disc arranged on the guide sleeve 24 can increase the contact area with the workpiece, thereby increasing the friction force, thereby driving the workpiece to rotate when the guide sleeve 24 rotates.

[0037] Furthermore, a support rod 25 is slidably mounted on the guide sleeve 24, and the support rod 25 is semi-cylindrical. The support rods 25 on the two groups of guide sleeves 24 cooperate with each other and form an integral column when fitted together. The support rods 25 on the two groups of guide sleeves 24 have one group of arc surfaces facing the ground and one group of arc surfaces facing vertically upward. During the clamping process, the workpiece is preferentially placed on the support rod 25 with the arc surface facing vertically upward, to facilitate the insertion of the support rod 25 on the opposite side into the workpiece.

[0038] In the above technical solution, the two groups of workpieces are symmetrically attached and placed on the support rod 25, and then the two groups of movable seats 22 are driven to approach each other through the bidirectional screw 21. As the two groups of movable seats 22 approach each other, the guide sleeve 24 is pressed against the workpiece and gradually moved to the center. Then, when the guide sleeve 24 can no longer approach, with the cooperation of the guide column 241 and the spring-shaped guide groove 231, the guide sleeve 24 rotates until it presses against the trigger member 34 and the fixing member 35 and stops. At this time, the two groups of workpieces are in symmetrical positions. When the workpieces are rotated, the centrifugal force at the protrusions of the workpieces is reduced, the stability of the rotation is maintained, and the resistance and imbalance during rotation are reduced.

[0039] The rotating assembly 3 includes two sets of fixed rings 31 arranged on the workbench 1 and a movable ring 32 located between the two sets of fixed rings 31 and drivingly connected to the driving member 11. The movable ring 32 is rotatably connected to the fixed ring 31, and a sealing member is arranged between them. The rotating seal is a prior art and will not be described in detail here. The fixed ring 31 is arranged on the workbench 1 through a bracket, and an air inlet hole is arranged in the bracket. A booster device is arranged at the air inlet end of the air inlet hole. The booster device is used to inflate and pressurize the fixed ring 31. An air inlet pipe 311 extending into the movable ring 32 is arranged on the fixed ring 31. When the inlet is not connected, the air inlet pipe 311 is arranged on the fixed ring 31. When the air pipe 311 is opened, there is no air pressure in the movable ring 32. When the air inlet pipe 311 is opened, gas is filled into the movable ring 32. Since the movable ring 32 is provided with multiple groups of pneumatic jaws 33, the pneumatic jaws 33 will extend and clamp the workpiece after the movable ring 32 is pressurized. A trigger member 34 is provided on the movable ring 32, and the trigger member 34 is provided with an air guide column 342 movably connected to the air inlet pipe 311, and an air guide hole 3421 is provided on the air guide column 342. The air guide hole 3421 is used to connect the air inlet pipe 311 to inflate and pressurize the movable ring 32 after the air guide column 342 is pressurized, so as to push out the pneumatic jaws 33 to clamp the workpiece.

[0040] The trigger member 34 further includes a fixing sleeve 341 , and the air guide column 342 is elastically connected to the fixing sleeve 341 . The air guide column 342 always extends out of the fixing sleeve 341 , and retracts after being squeezed by the workpiece, and limits the rotation of the workpiece when the workpiece abuts against the fixing sleeve 341 .

[0041] In addition, a fixing member 35 is provided on the movable ring 32, and the fixing member 35 and the trigger member 34 are distributed in a ring array on the inner wall of the movable ring 32, giving the movable ring 32 additional weight to increase stability during rotation.

[0042] In addition, a gear is provided at the driving end of the driving member 11, and a gear ring 321 meshing with the gear is provided on the outer wall of the movable ring 32. The gear is driven by the driving member 11 to drive the gear ring 321 and the movable ring 32 to rotate on the fixed ring 31, and the tool is cooperated for processing. It is worth mentioning that an auxiliary disk 4 is also included. Multiple groups of balls 41 are provided on both sides of the auxiliary disk 4. When the two groups of workpieces are placed on the support rod 25, the auxiliary disk 4 is placed between the two groups of workpieces. When the two groups of guide sleeves 24 are against the workpieces and drive the workpieces to rotate, since the two groups of workpieces do not stop when they rotate at the same angle, when one group stops rotating and the other group continues to rotate, the rotational friction between the workpieces is reduced by the balls 41 on both sides of the auxiliary disk 4.

[0043] In the above technical solution, when the workpiece is pushed into the rotating component 3 by the correction component 2, when the two groups of workpieces rotate to the point where they cannot rotate anymore, the air guide column 342 on the trigger member 34 will be squeezed to retract into the fixed sleeve 341. At the same time, the air guide column 342 descends and slides on the air inlet pipe 311, connecting the air guide hole 3421 with the air inlet pipe 311. At this time, the high-pressure gas filled in the fixed ring 31 through the outside will be introduced into the movable ring 32, thereby pushing the multiple groups of pneumatic clamps 33 to extend and clamp the workpiece, thereby realizing automatic clamping of the workpiece.

[0044] Working principle: When clamping the workpiece, first symmetrically fit the two groups of workpieces and place them on the support rod 25, and place a group of auxiliary disks 4 between the two groups of workpieces, so that the balls 41 on both sides of the auxiliary disks 4 are pressed against the workpieces, and then the two groups of movable seats 22 are driven to approach each other through the bidirectional screw 21, and in the process of the two groups of movable seats 22 approaching each other, the guide sleeve 24 is pressed against the workpiece and gradually moved to the center, and then when the guide sleeve 24 can no longer approach, the guide sleeve 24 will squeeze the elastic member 26 and retract into the movable sleeve 23, and at this time, with the cooperation of the guide column 241 and the spring-shaped guide groove 231, the guide sleeve 24 rotates and drives the workpiece to rotate, because the trigger member 34 and the fixing member 35 are set at different positions, and when the workpiece is initially placed, the protrusion will be vertically facing downward under the influence of gravity. Therefore, the two groups of workpieces will not be restricted at the same time when they rotate. When the workpieces rotate until they are against the trigger member 34 and the fixing member 35, the two groups of workpieces are in symmetrical positions. When the two groups of workpieces rotate to the point where they cannot rotate, the workpieces will squeeze the air guide column 342 on the trigger member 34 and retract it into the fixing sleeve 341. At the same time, the air guide column 342 descends and slides on the air inlet pipe 311, connecting the air guide hole 3421 with the air inlet pipe 311. At this time, the high-pressure gas filled in the fixing ring 31 through the outside will be introduced into the movable ring 32, thereby pushing the multiple groups of pneumatic clamps 33 to extend and clamp the workpiece, thereby realizing automatic clamping of the workpiece. When the workpiece is rotated, the centrifugal force at the protrusion of the workpiece is reduced, the stability of the rotation is maintained, and the resistance and imbalance during rotation are reduced.

[0045] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
