Description

Technical Field

[0001] This utility model belongs to the field of motor housing processing technology, and in particular relates to a clamping structure for motor housing processing. Background Technology

[0002] Motor housing machining typically involves multiple stages. The specific processes and steps depend on the material, shape, machining accuracy requirements, and production volume of the motor housing. Motor housings are generally made of metal materials such as aluminum alloy, cast iron, or steel, and have a certain degree of complex shape. In particular, the design has many internal and external circular holes, grooves, protrusions, or precision surface requirements, thus requiring fine machining processes.

[0003] According to a motor housing processing fixture disclosed in the publication (publication number: CN218427011U), the upper part of the fixture base is provided with an adjustment component, and the bottom of the fixture base is installed with an angle component. The adjustment component includes an adjustment seat rotatably mounted on the upper part of the fixture base. A fixed clamping seat is fixedly mounted on one side of the upper part of the adjustment seat, and a movable clamping seat is slidably connected to the other side of the upper part of the adjustment seat. Anti-slip pads are installed on the opposite surfaces of the fixed clamping seat and the movable clamping seat. An inner support seat is fixedly mounted in the middle of the outer wall of the fixed clamping seat, and the inner support seat is provided with a support mechanism. The angle component is installed on an angle adjustment seat at the bottom of the fixture base, and a rotating shaft is rotatably connected to the middle of the interior of the angle adjustment seat.

[0004] In the aforementioned application, although the motor housing can be clamped by adjusting the precise fit between the component and the angle component, the flat surface of the fixed clamping seat and the circular structure of the motor housing itself make this design unable to provide sufficient stable clamping in practical applications. This is because the contact surface between the flat surface of the fixed clamping seat and the motor housing is only at a limited number of points, resulting in uneven distribution of clamping force. This may cause the motor housing to undergo slight displacement or rotation during processing, thereby affecting its processing accuracy and stability. Therefore, we propose a clamping structure for motor housing processing. Utility Model Content

[0005] The purpose of this utility model is to provide a clamping structure for motor housing processing. Through the design of components such as the motor, stabilizing rod and rubber plate of the clamping mechanism, the problems of unstable clamping and inability to adapt to motor housings of different sizes in the prior art are solved.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a clamping structure for processing motor housings, including a worktable, a placement plate fixedly connected to the top of the worktable, and a clamping mechanism provided on the top of the placement plate. The clamping mechanism includes a motor, which is fixedly connected to the side of the worktable. The output shaft of the motor is fixedly connected to a double-guide threaded rod. A threaded sleeve is threadedly connected to the circumferential surface of the double-guide threaded rod. A stabilizing rod is fixedly connected to the circumferential surface of the threaded sleeve. A clamp is fixedly connected to the end of the stabilizing rod away from the threaded sleeve. An insert groove is provided inside the clamp. A rubber plate is installed inside the insert groove. The purpose is to ensure that the motor housing can be clamped stably and accurately during the processing.

[0007] Furthermore, a limiting rod is fixedly connected to the side of the motor, and one end of the limiting rod is slidably connected to the side of the threaded sleeve. The purpose of this is to ensure that the threaded sleeve does not rotate during movement.

[0008] Furthermore, the initial state of the rubber plate protrudes into the groove, the purpose of which is that during the clamping process, the elastic part of the rubber plate can make close contact with the surface of the motor housing, and fit the motor surface to tightly wrap it.

[0009] Furthermore, there are two of the threaded sleeve, clamp, and rubber plate, which are symmetrical to each other along the vertical central axis of the worktable. The purpose of this is to ensure the uniform distribution of clamping force and the stability of the workpiece during the processing.

[0010] Furthermore, a central positioning mechanism is provided on the top of the workbench. The central positioning mechanism includes a positioning column, which is fixedly connected to the top of the placement tray. A storage groove is provided on the circumferential surface of the positioning column. A positioning spring is fixedly connected inside the storage groove. A positioning block is elastically connected to the storage groove through the positioning spring. The purpose is to ensure that the motor housing can be kept in the center of the placement tray.

[0011] Furthermore, there are two of the positioning springs, positioning blocks, and receiving slots, which are symmetrical to each other along the vertical central axis of the placement plate. The purpose is to ensure uniform clamping and stability when placing and positioning workpieces.

[0012] Furthermore, the size of the positioning block is adapted to the size of the storage slot. The purpose is to ensure the precise positioning and stable fixation of the workpiece on the placement tray. By precisely matching the size of the positioning block and the storage slot, it can be ensured that the positioning block can be perfectly embedded in the storage slot, thereby making the workpiece more accurately positioned when placed and reducing the error caused by movement or tilting during processing.

[0013] This utility model has the following beneficial effects: 1. This utility model utilizes the cooperation between components such as the motor, stabilizing rod, and rubber plate of the clamping mechanism. The motor drives the double guide threaded rod to rotate. Under the constraint of the limiting rod, the two threaded sleeves move synchronously along the threaded rod, causing the clamp to move closer to the center. The rubber plate initially protrudes from the inlay groove. When clamping the outer circle of the motor housing, the rubber plate is deformed under pressure, conforming to the curved surface to form a uniform and flexible clamping, effectively increasing the contact area, preventing slippage and surface damage, and adapting to motor housings of different sizes.

[0014] 2. This utility model utilizes the cooperation between components such as the positioning column, positioning spring, and positioning block of the central positioning mechanism. When using this clamping structure, the motor housing to be processed is placed on the placement plate, with the inner hole fitted outside the positioning column. The inner wall of the motor housing contacts the positioning block, compressing the positioning spring and retracting into the receiving groove to achieve initial centering. After the motor housing is in place, the positioning spring pushes the positioning block outward, making elastic contact with the inner wall, automatically centering and providing stable support, ensuring that the axis is consistent with the processing datum.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. 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 skilled in the art without creative effort are within the scope of protection of the present utility model.

[0018] Please see Figures 1-4 This utility model is a clamping structure for processing motor housing, including a worktable 1, a placement plate 2 fixedly connected to the top of the worktable 1, and a clamping mechanism 3 provided on the top of the placement plate 2. The clamping mechanism 3 includes a motor 31, which is fixedly connected to the side of the worktable 1. The output shaft of the motor 31 is fixedly connected to a double-guide threaded rod 32. A threaded sleeve 33 is threadedly connected to the circumferential surface of the double-guide threaded rod 32. A stabilizing rod 34 is fixedly connected to the circumferential surface of the threaded sleeve 33. A clamp 35 is fixedly connected to the end of the stabilizing rod 34 away from the threaded sleeve 33. An inlay groove 36 is provided inside the clamp 35. A rubber plate 37 is provided inside the inlay groove 36. The purpose is to ensure that the motor housing can be clamped stably and accurately during the processing.

[0019] A limiting rod 38 is fixedly connected to the side of the motor 31. One end of the limiting rod 38 passes through and slides through the side of the threaded sleeve 33. The purpose is to ensure that the threaded sleeve 33 does not rotate during movement.

[0020] The initial state of the rubber plate 37 protrudes into the groove 36. Its purpose is to ensure that the elastic part of the rubber plate 37 can make close contact with the surface of the motor housing during the clamping process, and fit the motor surface tightly to wrap it.

[0021] There are two threaded sleeves 33, clamps 35 and rubber plates 37, which are symmetrical about each other along the vertical central axis of the worktable 1. The purpose is to ensure the uniform distribution of clamping force and the stability of the workpiece during the processing.

[0022] The top of the workbench 1 is provided with a center positioning mechanism 4, which includes a positioning post 41. The positioning post 41 is fixedly connected to the top of the placement tray 2. A storage groove 44 is opened on the circumferential surface of the positioning post 41. A positioning spring 42 is fixedly connected inside the storage groove 44. A positioning block 43 is elastically connected to the storage groove 44 through the positioning spring 42. The purpose is to ensure that the motor housing can be kept in the center of the placement tray 2.

[0023] There are two positioning springs 42, positioning blocks 43 and receiving slots 44, which are symmetrical to each other along the vertical central axis of the placement plate 2. The purpose is to ensure uniform clamping and stability when placing and positioning workpieces.

[0024] The size of the positioning block 43 is matched with the size of the storage groove 44. The purpose is to ensure the precise positioning and stable fixation of the workpiece on the placement tray 2. By precisely matching the size of the positioning block 43 and the storage groove 44, it can be ensured that the positioning block 43 can be perfectly embedded in the storage groove 44, so that the workpiece is placed more accurately and the error caused by movement or tilting during the processing is reduced.

[0025] One specific application of this embodiment is as follows: Before using this clamping structure, the motor 31 needs to be connected to the power supply and control system, and the smooth operation and accurate positioning of moving parts such as the double guide threaded rod 32, threaded sleeve 33, and stabilizing rod 34 should be checked. When using this clamping structure, the motor housing to be processed is first placed on the placement plate 2, so that its inner hole fits outside the positioning post 41. During the placement process, the inner wall of the motor housing contacts the positioning block 43, pushing the positioning block 43 to compress the positioning spring 42 and retract into the receiving groove 44, achieving initial centering. When the motor housing is fully in place, the positioning spring 42 pushes the positioning block 43 to pop outward, forming elastic contact with the inner wall of the motor housing, realizing the motor housing's positioning. The automatic centering and stabilization of the motor housing in the horizontal direction ensures that its axis is consistent with the machining datum. Then, the motor 31 is started, driving the double guide threaded rod 32 to rotate. Under the constraint of the limit rod 38, the two threaded sleeves 33 move synchronously towards each other along the double guide threaded rod 32. The stabilizing rod 34 drives the clamps 35 on both sides to move closer to the center. The rubber plate 37 on the inner side of the clamp 35 initially protrudes from the inlay groove 36. When the clamp 35 clamps the outer circle of the motor housing, the rubber plate 37 is compressed and undergoes elastic deformation, fully conforming to the curved surface of the motor housing, forming a uniform and flexible covering clamp, effectively increasing the contact area, preventing workpiece slippage or surface damage, and adapting to motor housings of different sizes.
