Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically a deburring structure for the bearing housing of an air conditioning compressor in a new energy vehicle. Background Technology

[0002] In the production of air conditioning compressors for new energy vehicles, deburring the edges and corners of bearing housings is a crucial process. Existing equipment for deburring bearing housing edges and corners typically suffers from problems such as insufficient workpiece positioning stability, cumbersome multi-directional deburring operations, inconvenient debris removal, and low efficiency in changing fixture specifications. For example, traditional limiting structures often use mechanical clips or bolts for fixing, which is not only time-consuming to install and disassemble but also difficult to adapt to rapid switching between different bearing housing specifications. During deburring, adjusting the workpiece angle requires multiple manual disassemblies and reassemblies, resulting in low production efficiency. Furthermore, residual debris easily accumulates on the equipment surface, affecting subsequent processing accuracy. In addition, the existing equipment's support structure lacks a reliable support and reset mechanism when the workpiece rotates and changes position, further restricting the improvement of automation levels.

[0003] To address the aforementioned problems, this utility model provides a deburring structure for the bearing housing of an air conditioning compressor in new energy vehicles. It utilizes a limiting clamping plate assembly with a movable mounting plate and support plate, employing an electric push rod to quickly clamp and release the bearing housing. A first motor drives the support plate to rotate, while a second motor and a bidirectional lead screw control the movable plate support structure, enabling the repositioning of the limiting clamping plate and the centralized collection of debris. Simultaneously, the combination of permanent magnet adsorption and limiting bracket engagement solves the problem of convenient replacement of limiting clamping plates of different specifications, effectively improving the operational efficiency and automation of deburring the bearing housing edges. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides a deburring structure for the bearing housing of an air conditioning compressor in new energy vehicles.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A deburring structure for the bearing housing of an air conditioning compressor in a new energy vehicle includes a worktable, an electric push rod, a first motor, and a second motor. A first fixing plate is fixedly connected to the top of the worktable, and a second fixing plate is fixedly connected to the top of the first fixing plate. The electric push rod is fixedly connected to the bottom of the second fixing plate, and a mounting plate is fixedly connected to the movable end of the electric push rod. A fixing groove is formed through the top of the worktable. The first motor is mounted on the inner rear wall of the fixing groove. A drive rod is fixedly connected to the drive end of the first motor, and a support plate is fixedly connected to the drive rod. Limiting brackets are fixedly connected to the bottom of the mounting plate and the upper and lower surfaces of the support plate. Limiting clamps are movably engaged inside the limiting brackets. Permanent magnets are provided inside both the mounting plate and the support plate. Multiple limiting clamps are respectively attracted to the bottom of the mounting plate and the upper and lower surfaces of the support plate. The bottom limiting clamp of the mounting plate is located directly above the upper limiting clamp of the support plate. Slots are opened on both inner walls of the fixing groove. The second motor is fixedly connected to the inner wall of the slot. A bidirectional lead screw is fixedly connected to the drive end of the second motor. The bidirectional threads of the bidirectional lead screw are threaded to movable plates.

[0006] Preferably, one end of each of the two movable plates is slidably engaged inside the two slots, and the other end of each of the two movable plates is in contact with both ends of the lower surface of the support plate.

[0007] Preferably, the bidirectional lead screw is located behind the support plate.

[0008] Preferably, the surface of the limiting clamp is configured as an anti-slip arc surface.

[0009] Compared with the prior art, the beneficial effects of this utility model are: 1. To address the issues of time-consuming installation and disassembly of traditional limiting structures and difficulty in adapting to different specifications of bearing seats, a limiting clamp is adopted that is movably snapped into the limiting bracket and attracted by the permanent magnet inside the mounting plate and the support plate. This allows the limiting clamp to be quickly replaced, significantly improving the switching efficiency of different specifications of clamps. 2. To address the issues of insufficient workpiece positioning stability and cumbersome multi-directional deburring operations, an electric push rod is used to drive the limit clamping plates on the mounting plate and support plate to move up and down, enabling the bearing seat to be quickly clamped and released. Combined with the rotatable structure of the support plate, the position of the bearing seat to be processed can be adjusted by rotation without the need for multiple disassembly and assembly of the workpiece. This ensures positioning stability and simplifies the multi-directional deburring operation process. 3. To address the problem of inconvenient debris removal, the first motor drives the support plate to rotate, causing the debris generated during the deburring process to be concentrated in the fixed groove as the support plate rotates, making it easy for operators to collect and preventing debris accumulation from affecting processing accuracy. 4. To address the lack of a reliable mechanism in the existing equipment support structure during workpiece repositioning, a second motor is used to drive a bidirectional lead screw to control the movement of the movable plate. Before the support plate rotates, the support is released by moving the movable plate, and after the rotation is completed, the support is reset, forming a stable support and repositioning linkage mechanism, which improves the automation level of the equipment.

[0012] Example

[0013] Please see Figure 1 A deburring structure for the bearing housing of an air conditioning compressor in a new energy vehicle includes a worktable 1, an electric push rod 4, a first motor 8, and a second motor 13. A first fixing plate 2 is fixedly connected to the top of the worktable 1, and a second fixing plate 3 is fixedly connected to the top of the first fixing plate 2. The electric push rod 4 is fixedly connected to the bottom of the second fixing plate 3, and a mounting plate 5 is fixedly connected to the movable end of the electric push rod 4. A fixing groove 10 is formed through the top of the worktable 1. The first motor 8 is mounted on the inner rear wall of the fixing groove 10. A drive rod 9 is fixedly connected to the drive end of the first motor 8, and a support plate 11 is fixedly connected through the drive rod 9. The bottom of the mounting plate 5... Limiting brackets 6 are fixedly connected to both the upper and lower surfaces of the support plate 11. Limiting clamps 7 are movably engaged inside the limiting brackets 6. Permanent magnets are provided inside both the mounting plate 5 and the support plate 11. Multiple limiting clamps 7 are respectively attached to the bottom of the mounting plate 5 and the upper and lower surfaces of the support plate 11. The bottom limiting clamp 7 of the mounting plate 5 is located directly above the upper limiting clamp 7 of the support plate 11. The two inner walls of the fixing groove 10 are provided with slots 12. The second motor 13 is fixedly connected to the inner wall of the slot 12. The drive end of the second motor 13 is fixedly connected to a bidirectional lead screw 14. The bidirectional threads of the bidirectional lead screw 14 are threadedly connected to movable plates 15.

[0014] One end of each of the two movable plates 15 is slidably engaged inside the two slots 12, and the other ends of each movable plate 15 are in contact with the two ends of the lower surface of the support plate 11. Through the sliding engagement of the movable plates 15 with the slots 12, an adjustable support structure for the support plate 11 is formed. When it is necessary to rotate the support plate 11, the movable plates 15 can move smoothly along the slots 12 to release the support, avoiding interference with the rotation of the support plate 11. After rotation, the movable plates 15 return to their original position and contact the lower surface of the support plate 11, providing stable support again and ensuring the positioning accuracy of the support plate 11 under different working conditions.

[0015] The bidirectional lead screw 14 is located behind the support plate 11. This layout design separates the drive structure of the bidirectional lead screw 14 from the rotation area of ​​the support plate 11, effectively avoiding spatial interference between components. This ensures that when the bidirectional lead screw 14 drives the movable plate 15 to move, it will not obstruct the rotation trajectory of the support plate 11. At the same time, it facilitates the installation and maintenance of drive components such as the second motor 13, and improves the overall structural compactness and operational reliability.

[0016] The surface of the limiting clamp 7 is designed as an anti-slip arc surface. The anti-slip arc surface is adapted to the shape of the outer surface of the bearing seat. By increasing the contact area and the coefficient of friction, the clamping force of the limiting clamp 7 on the bearing seat is enhanced, which effectively prevents the bearing seat from shifting due to grinding vibration during the deburring process, ensures stable workpiece positioning, and thus improves the accuracy and consistency of deburring.

[0017] The working principle of this utility model is as follows: When using the deburring structure for the bearing housing of a new energy vehicle air conditioning compressor, the operator first places the bearing housing to be deburred onto the anti-slip arc surface of the upper limit clamp 7 on the support plate 11. Then, the operator drives the lower limit clamp 7 of the mounting plate 5 at its movable end to move downwards via the electric push rod 4, so that the limit clamp 7 of the mounting plate 5 and the limit clamp 7 of the support plate 11 limit and fix the bearing housing. After that, the operator uses a grinding device to grind the burrs on the edges of the bearing housing. After the burrs on both sides of the bearing housing are deburred, the operator drives the limit clamp 7 on the mounting plate 5 to move upwards via the electric push rod 4, releasing the bearing housing. Then, the operator rotates the limit clamp 7 on the support plate 11 so that the edges of the bearing housing to be deburred are located on both sides. The operator then uses the electric push rod 4 to fix the bearing housing by the two limit clamps 7. Repeating the above grinding process completes the deburring of the bearing housing edges. After the bearing housing deburring is completed, the electric push rod 4 drives the mounting plate 5 to reset. At this time, the second motor 13 in the slot 12 drives the bidirectional lead screw 14 to rotate. Since the two movable plates 15 on the bidirectional lead screw 14 are respectively limited by the two slots 12, the two movable plates 15 are driven to move away from the support plate 11, so that the movable plates 15 no longer support the bottom of the support plate 11. This allows the first motor 8 to drive the drive rod 9 to rotate the support plate 11, thereby causing the two limiting clamps 7 on the upper and lower surfaces of the support plate 11 to switch positions. At the same time, the debris generated from the deburring of the bearing housing remaining on the support plate 11 and the limiting clamps 7 will be concentrated in the fixed groove 10 due to the rotation of the support plate 11, making it easy for the operator to collect the debris from below the fixed groove 10. Afterwards, the second motor 13 drives the movable plates 15 to reset, so that the two movable plates 15 can support the support plate 11 again. Furthermore, since the limiting clamp 7 is movably engaged within the limiting bracket 6, and both the mounting plate 5 and the support plate 11 are equipped with permanent magnets, multiple limiting clamps 7 are respectively attracted to the bottom of the mounting plate 5 and the upper and lower surfaces of the support plate 11, making it convenient to replace limiting clamps 7 of different specifications.
