Description

Technical Field

[0001] This utility model relates to the field of machining tooling technology, specifically to a machining tooling for a new energy motor housing. Background Technology

[0002] New energy motor housing processing fixtures are specialized equipment used in the production process of new energy motors to achieve precise positioning, stable clamping, and auxiliary processing of motor housings.

[0003] In the processing and production of new energy motor housings, the clamping process of the machining fixture is the core step for achieving precise positioning and stable processing of the motor housing. The clamping mechanism needs to transfer the motor housing from the conveyor belt or worktable to the processing position and complete the placement action. When the clamping mechanism releases the clamping force on the new energy motor housing to achieve the lowering action, due to the mass of the new energy motor housing itself, it will have a downward movement tendency under the action of gravity. At the moment of contact with the machining fixture, the gravitational potential energy carried by the motor housing will be rapidly converted into kinetic energy and transferred to the contact part of the fixture, thus forming an instantaneous impact force between the motor housing and the fixture. New energy motor housings are usually made of lightweight alloy materials such as aluminum alloys. Although such materials can meet the requirements of motor lightweighting, the impact resistance of the material itself is weak. Under the action of the above-mentioned instantaneous impact force, the surface area of ​​the motor housing in contact with the fixture is prone to plastic deformation, which manifests as surface dents, scratches and other appearance damage. Utility Model Content

[0004] The purpose of this utility model is to provide a processing fixture for a new energy motor housing. This processing fixture for a new energy motor housing solves the problem of plastic deformation on the surface when the motor housing is lowered during the clamping process of the processing fixture.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A machining fixture for a new energy motor housing includes a worktable with a buffer mechanism. The buffer mechanism includes a support frame with a stepper motor connected to it. The output shaft of the stepper motor is fixedly connected to a U-shaped support arm. Two support rings are symmetrically connected to the U-shaped support arm. A support column is slidably connected to the inner wall of each support ring. A hollow positioning ring is fixedly connected to the top of each support column. A return spring is connected between the hollow positioning ring and the support ring. A hollow cylinder is fixedly connected to the bottom of each support ring. A through groove is formed on the side wall of the hollow cylinder. A positioning disc is fixedly connected to the bottom of each support column. The outer wall of the positioning disc is slidably connected to the inner wall of the hollow cylinder. A positioning bolt is bolted to the side wall of the positioning disc, and the positioning bolt passes through the through groove to fix the positioning disc after clamping. Clamping mechanisms are provided on the two hollow positioning rings for clamping the new energy motor housing.

[0007] Preferably, the workbench is equipped with a conveyor belt for transporting the motor housing.

[0008] Preferably, the U-shaped support arm is rotatably connected to the support frame to support the stable rotation of the U-shaped support arm.

[0009] Preferably, the end of the positioning bolt away from the positioning disc is provided with a rotating handle for easy rotation of the positioning bolt.

[0010] Preferably, the clamping mechanism includes an input tube, which is fixedly connected to the hollow positioning ring on the right side. A side support cylinder is fixedly connected to the hollow positioning ring on the left side. A hollow ring connects the side support cylinder and the input tube. An air pump is connected to the end of the input tube away from the hollow ring. Several output hollow columns are arranged in a circumferential array on the inner wall of the hollow ring. A guide rod is slidably connected to the inner wall of the output hollow column. A sealing disc is fixedly connected to one end of the guide rod. The outer wall of the sealing disc is piston-connected to the inner wall of the sealing disc. A flexible ball is fixedly connected to the other end of the guide rod. The flexible ball is used to clamp the new energy motor housing by contacting it.

[0011] Preferably, the inner wall of the support ring is provided with a guide sleeve for sliding guidance of the support column, reducing frictional resistance and improving sliding accuracy.

[0012] Preferably, the support frame is fixed to the worktable with bolts to facilitate the disassembly of the support frame.

[0013] By means of the above technical solution, this utility model provides a processing tooling for a new energy motor housing.

[0014] It has at least the following beneficial effects:

[0015] 1. This utility model incorporates a buffer mechanism. When the new energy motor housing is placed on the clamping mechanism of the hollow positioning ring, the support column moves downward along the inner wall of the support ring under gravity, causing the hollow positioning ring to move downward synchronously and compress the return spring. The elastic buffering force generated by the return spring can prevent damage to the motor housing caused by impact during placement. At the same time, the positioning disc at the bottom of the support column slides along the inner wall of the hollow cylinder. With the limiting effect of the positioning bolt and the through groove, tightening the positioning bolt after clamping can lock the position of the support column and the hollow positioning ring, effectively preventing the motor housing from sliding up and down during processing and ensuring processing stability.

[0016] 2. This utility model incorporates a clamping mechanism. Gas generated by the air pump enters the hollow ring through the input pipe, pushing the sealing disc and guide rod inside the output hollow column to move. This causes the flexible ball to extend and contact the inner wall of the motor housing. Since the flexible ball can adaptively adjust its extension length according to the irregular contour of the inner wall of the motor housing, the inner wall parts closer to the center first contact and prevent the corresponding flexible ball from extending further, while the parts farther from the center allow the corresponding flexible ball to extend further. Ultimately, all the flexible balls form multi-point contact along the inner wall contour. Combined with the deformation characteristics of the flexible ball itself, it can adaptively compensate for shape errors, applying radial clamping force to the motor housing from multiple directions to prevent displacement or rotation during processing, thus achieving stable clamping of different outer wall parts.

[0026] 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.

[0027] Please see Figure 1 - Figure 7As shown, this utility model provides a technical solution: a processing fixture for a new energy motor housing, including a worktable 1, on which a buffer mechanism 3 is provided. The buffer mechanism 3 includes: a support frame 31, a stepper motor 32 connected to the support frame 31, a U-shaped support arm 33 fixedly connected to the output shaft of the stepper motor 32, two support rings 34 symmetrically connected to the U-shaped support arm 33, a support column 35 slidably connected to the inner wall of the support ring 34, a hollow positioning ring 36 fixedly connected to the top of the support column 35, a return spring 37 connected between the hollow positioning ring 36 and the support ring 34, and a hollow cylinder 38 fixedly connected to the bottom of the support ring 34. A through groove 39 is opened on the side wall of the hollow cylinder 38. A positioning disc 310 is fixedly connected to the bottom of the support column 35. The outer wall of the positioning disc 310 is slidably connected to the inner wall of the hollow cylinder 38. A positioning bolt 311 is bolted to the side wall of the positioning disc 310. The positioning bolt 311 passes through the through groove 39 and is used to fix the positioning disc 310 after clamping. A clamping mechanism 4 is provided on the two hollow positioning rings 36 for clamping the new energy motor shell. The workbench 1 serves as the basic load-bearing component supporting the buffer mechanism 3. The support frame 31 of the buffer mechanism 3 is installed on the workbench 1 to provide stable support. A stepper motor 32 fixedly connected to the support frame 31 serves as the power source. Its output shaft directly drives the U-shaped support arm 33 to rotate to adjust the U-shaped support arm 3. In the spatial arrangement of the U-shaped support arm 33, two symmetrically connected support rings 34 move synchronously with the U-shaped support arm 33 to achieve symmetrical support. The inner wall of the support ring 34 is slidably connected to the support column 35, allowing the support column 35 to slide up and down along the inner wall of the support ring 34. The hollow positioning ring 36 fixed at the top of the support column 35 moves synchronously with the support column 35 to support the new energy motor housing. The clamping mechanism 4 set on the two hollow positioning rings 36 is used to clamp the new energy motor housing placed on the hollow positioning rings 36. The return spring 37 connected between the hollow positioning ring 36 and the support ring 34 is compressed when the support column 35 drives the hollow positioning ring 36 to move downward, thereby generating an elastic buffering force, so that the new energy motor housing can be supported. The impact force during the clamping process of the housing is buffered. The hollow cylinder 38 fixed at the bottom of the support ring 34 provides a sliding channel for the positioning disc 310 at the bottom of the support column 35. The through groove 39 opened on the side wall of the hollow cylinder 38 restricts the movement range of the positioning bolt 311 connected to the side wall bolt of the positioning disc 310, so that the positioning disc 310 can only slide up and down along the inner wall of the hollow cylinder 38. After the clamping is completed, the positioning bolt 311 fixes the positioning disc 310 by cooperating with the through groove 39, thereby locking the position of the support column 35 and the hollow positioning ring 36, thereby locking the clamping mechanism 4 on the hollow positioning ring 36 to prevent up and down sliding and to prevent the new energy motor housing on the clamping mechanism 4 from sliding randomly during the processing.

[0028] In this embodiment, a conveyor belt 2 is provided on the workbench 1 to transport the motor housing, reduce manual handling operations, realize the continuous transfer of workpieces between processing stations, thereby improving overall production efficiency and automation.

[0029] Furthermore, the U-shaped support arm 33 is rotatably connected to the support frame 31 to support the stable rotation of the U-shaped support arm 33, enabling the U-shaped support arm 33 to rotate smoothly around the support frame 31, and to achieve flexible rotation and positioning when adjusting the clamping position or loading and unloading the motor housing.

[0030] In addition, a rotating handle is provided at the end of the positioning bolt 311 away from the positioning disc 310, which is used to facilitate the rotation of the positioning bolt 311. This allows the operator to directly tighten or loosen the positioning bolt 311 manually without the need for additional tools, thus improving the convenience and efficiency of positioning adjustment.

[0031] In addition, the clamping mechanism 4 includes an input pipe 41, which is fixedly connected to the right hollow positioning ring 36. A side support cylinder 43 is fixedly connected to the left hollow positioning ring 36. A hollow ring 42 connects the side support cylinder 43 and the input pipe 41. An air pump 44 is connected to the end of the input pipe 41 away from the hollow ring 42. Several output hollow columns 45 are arranged in a circumferential array on the inner wall of the hollow ring 42. A guide rod 46 is slidably connected to the inner wall of the output hollow column 45. A sealing disc 47 is fixedly connected to one end of the guide rod 46. The outer wall of the sealing disc 47 is sealed with a sealing disc 47. The inner wall of the sealing disc 47 is connected to a piston. The other end of the guide rod 46 is fixedly connected to a flexible ball block 48, which is used to clamp the new energy motor housing. The air pump 44, as a power source, delivers gas to the hollow ring 42 through the input pipe 41. The output hollow columns 45, arranged in a circumferential array on the inner wall of the hollow ring 42, are connected to the inside of the hollow ring 42. The guide rod 46, which is slidably connected to the inner wall of the output hollow column 45, has one end fixed to the sealing disc 47 and the other end fixed to the flexible ball block 48. When the gas pressure inside the hollow ring 42 increases, the gas pressure acts on the sealing disc inside the output hollow column 45. The disc 47 pushes the sealing disc 47 to slide along the inner wall of the output hollow column 45 away from the center of the hollow ring 42. The sealing disc 47 drives the guide rod 46 to move synchronously. The guide rod 46 pushes the flexible ball block 48 out of the output hollow column 45 and abuts against the new energy motor housing. The radial clamping of the new energy motor housing is achieved by the synchronous abutment of the motor housing by the circumferentially distributed flexible ball blocks 48. When the motor housing has an irregular contour, the inner wall part closer to the center will contact the corresponding flexible ball block 48 first and generate a reaction force to prevent the flexible ball block 48 from continuing to extend. This results in a shorter extension length at that location, while the inner wall portion farther from the center allows the corresponding flexible ball block 48 to continue extending, resulting in a longer extension length at that location, until all flexible ball blocks 48 are in contact with the inner wall and achieve force balance. At this point, the flexible ball blocks 48 with different extension lengths form multi-point contact along the inner wall contour of the motor housing. Combined with the flexible deformation characteristics of the flexible ball block 48 itself, it can adaptively compensate for the shape error of the inner wall of the motor housing, applying radial clamping force to the motor housing from multiple directions to prevent displacement or rotation during processing, thereby achieving stable clamping of different outer wall portions.

[0032] It is worth noting that the inner wall of the support ring 34 is provided with a guide sleeve, which is used to guide the support column 35 to slide, reduce frictional resistance and improve sliding accuracy. The support frame 31 is fixed to the worktable 1 with bolts to facilitate the disassembly of the support frame 31.

[0033] The workbench 1 serves as the basic load-bearing component supporting the entire fixture. The conveyor belt 2 on the workbench 1 is activated to transport the new energy motor housing to the processing station, reducing manual handling and enabling continuous workpiece transfer to improve production efficiency. The support frame 31 of the buffer mechanism 3 is fixed to the workbench 1, providing stable support. The stepper motor 32 on the support frame 31 is activated, and its output shaft drives the U-shaped support arm 33 to rotate around the support frame 31. Two symmetrically connected support rings 34 on the U-shaped support arm 33 rotate synchronously with it. When the motor housing is placed on the hollow positioning ring 36, the support column 35, which is slidably connected to the inner wall of the support ring 34, moves downward along the inner wall of the support ring 34 under the influence of gravity. The hollow positioning ring 36 at the top of the support column 35 carries the motor housing and moves downward accordingly. The return spring 37 between the support ring 34 and the support ring 34 is compressed to generate elastic buffering force, preventing damage to the motor housing due to impact during placement; the positioning disc 310 at the bottom of the support column 35 slides along the inner wall of the hollow cylinder 38 at the bottom of the support ring 34, and the positioning bolt 311 on the side wall of the positioning disc 310 moves down synchronously in the through groove 39 on the side wall of the hollow cylinder 38. At this time, the positioning bolt 311 is in a loosened state, and the rotating handle at its end facilitates subsequent operation; the clamping mechanism 4 on the two hollow positioning rings 36 starts to work, and the input pipe 41 on the right hollow positioning ring 36 introduces the gas generated by the air pump 44 into the hollow ring 42 between the side support column 43 and the input pipe 41. The side support column 43 and the input pipe 41 cooperate to support the hollow ring 42 to ensure structural stability. The gas inside the hollow ring 42 enters the output hollow column 45, which is part of the inner wall circumferential array. The gas pressure acts on the sealing disk 47 inside the output hollow column 45, pushing the sealing disk 47 to slide along the inner wall of the output hollow column 45. The sealing disk 47 drives the guide rod 46, which is fixedly connected to it, to move synchronously. The guide rod 46 pushes the flexible ball block 48 at the other end to extend out of the output hollow column 45 and abut against the inner wall of the new energy motor housing. According to the irregular contour of the inner wall of the motor housing, the inner wall part closer to the center first contacts the corresponding flexible ball block 48 to prevent it from extending further, while the inner wall part farther from the center allows the corresponding flexible ball block 48 to continue to extend. All flexible balls 48 achieve radial stable clamping through multi-point contact and adaptive compensation for shape errors. After clamping is completed, Tighten the positioning bolt 311 by rotating the handle at the end of the positioning bolt 311. The positioning bolt 311 cooperates with the through groove 39 to fix the positioning disc 310, thereby locking the position of the support column 35 and the hollow positioning ring 36, preventing the motor housing on the clamping mechanism 4 from sliding up and down during processing. After processing, rotate the handle of the positioning bolt 311 in the opposite direction to loosen the positioning bolt 311. The air pump 44 stops supplying air, causing the air pressure inside the hollow ring 42 to decrease. The sealing disc 47 drives the guide rod 46 and the flexible ball block 48 to return to their original position and detach from the inner wall of the motor housing. The return spring 37 resets and pushes the support column 35 and the hollow positioning ring 36 to move upward. The processed motor housing is removed and transferred to the next station via the conveyor belt 2, realizing the automation and stability of the entire processing flow.
