Description

Technical Field

[0001] The utility model relates to the technical field of motor end cover processing devices, in particular to a rolling and polishing device for the bearing chamber of a motor end cover. Background Art

[0002] Motor end covers are usually integrally formed by stamping with stamping equipment such as presses. A bearing chamber for installing a bearing is provided inside the motor end cover, and a bearing for enabling rotational connection between the motor end cover and the motor rotor is installed in the bearing chamber.

[0003] The inner wall of the bearing chamber of the motor end cover formed by stamping with stamping equipment usually has burrs. In order to ensure the fitting accuracy with the machine shell, it is necessary to improve the flatness of the overall fitting area and the perpendicularity with the bearing chamber of the end cover. Non-perpendicularity of the bearing chamber will affect the concentricity of the motor shaft and the machine shell, and easily cause adverse factors such as noise, vibration, and changes in motor cogging torque. In the prior art, it is difficult to smooth the inner wall of the bearing chamber so that the perpendicularity and dimensional tolerance of the bearing chambers of the same batch of motor end covers are maintained within a suitable range. Therefore, it is necessary to improve the relevant technology design. Summary of the Utility Model

[0004] In order to solve the above problems, the utility model provides a rolling and polishing device for the bearing chamber of a motor end cover.

[0005] The above technical purpose of the utility model is achieved by the following technical solutions: A rolling and polishing device for the bearing chamber of a motor end cover includes a machine body and a loading rack. Feed inlets and discharge outlets are respectively arranged on both sides of the machine body. One end of the loading rack extends into the feed inlet and is fixed to the machine body. A loading component for conveying the motor end cover to be polished into the machine body is arranged on the loading rack. A clamping component for clamping the motor end cover to be polished and a rolling and polishing component for performing rolling and polishing operations on the bearing chamber inside the motor end cover are arranged inside the machine body.

[0006] By adopting the above technical solutions, the loading component conveys the motor end cover to be polished into the machine body. After reaching below the rolling and polishing component, the clamping component clamps the motor end cover to be polished, and the rolling and polishing component can perform rolling and polishing operations on the bearing chamber inside the motor end cover, which is beneficial to maintaining the perpendicularity and dimensional tolerance of the bearing chamber within a suitable range.

[0007] Further, a column is fixed inside the machine body. The rolling and polishing component includes a power head arranged on the column and a rolling and polishing tool connected to the output end of the power head.

[0008] By adopting the above technical solutions, the power head is a power component that can both rotate and control the reciprocating movement of components. After the power head works, it can drive the rolling and polishing tool to rotate during the lifting process, thereby realizing the operation of rolling and polishing the bearing chamber of the motor end cover.

[0009] Further, a first mounting bracket is fixedly sleeved on the output end of the power head. A pressing assembly is arranged on the first mounting bracket. The pressing assembly includes a guide rod that penetrates through and is slidably fitted on the bottom plate of the first mounting bracket, an annular pressing plate fixed to the lower end of the guide rod, and a pressing spring sleeved on the guide rod. The upper and lower ends of the pressing spring are respectively fixed to the bottom of the bottom plate of the first mounting bracket and the top of the annular pressing plate, and the annular pressing plate is coaxially arranged with the burnishing tool.

[0010] By adopting the above technical solution, during the process of driving the burnishing tool to lift and lower at the output end of the power head, the first mounting bracket, the guide rod, the annular pressing plate and the pressing spring lift and lower synchronously. After the annular pressing plate presses the motor end cover, the stability of the bearing chamber of the motor end cover during the burnishing process is enhanced.

[0011] Further, the clamping assembly includes a longitudinal mounting seat arranged in the machine body, a longitudinal two-way lead screw rotatably mounted on the longitudinal mounting seat, a longitudinal motor arranged on the longitudinal mounting seat and used for driving the longitudinal two-way lead screw to rotate, a longitudinal sliding block sleeved on the longitudinal two-way lead screw and threadedly connected thereto, and a clamping plate arranged on the top of the longitudinal sliding block. Two sections of threads with equal pitches and opposite helix directions are arranged on the longitudinal two-way lead screw. The longitudinal sliding block is slidably connected to the longitudinal mounting seat. There are two longitudinal sliding blocks and they are symmetrically distributed on the two sections of threads of the longitudinal two-way lead screw. The clamping plates on both sides cooperate to clamp the motor end cover to be burnished.

[0012] By adopting the above technical solution, after the longitudinal motor works, it drives the longitudinal two-way lead screw to rotate. Since the two longitudinal sliding blocks are respectively threadedly connected to the two sections of threads of the longitudinal two-way lead screw and the longitudinal sliding block is slidably connected to the longitudinal mounting seat, the two longitudinal sliding blocks approach or move away from each other, so that the clamping plates on the two longitudinal sliding blocks approach or move away from each other, so as to clamp the motor end cover and the burnishing assembly performs the burnishing operation.

[0013] Further, a connecting seat is fixed to the top of each longitudinal sliding block. Two sliding seats are fixed to the top of the connecting seat.

A discharge pushing plate is fixed to the side of the second mounting bracket away from the feed port. A driving assembly is arranged in the machine body and is used for driving the longitudinal mounting seat to move towards the side close to or away from the feed port.

[0014] By adopting the above technical solution, after the motor end cover completes the burnishing operation, the driving assembly drives the longitudinal mounting seat to move towards the side away from the feed port until the discharge pushing plate pushes the motor end cover out of the discharge port. Subsequently, the driving assembly drives the longitudinal mounting seat to reset for the next burnishing operation.

[0015] Furthermore, a position sensor for monitoring whether there is a motor end cover in the area directly opposite the bottom of the monitoring tumbling tool is fixed inside the machine body.

[0016] By adopting the above technical solution, the setting of the position sensor enables the device to monitor the position of the motor end cover in real time, which is beneficial for the tumbling assembly to perform tumbling operations on the motor end cover.

[0017] Furthermore, a discharge hopper is fixed at the discharge port of the machine body, a processing table extending from the discharge port to a position near the feed port is fixed inside the machine body, and one end of the processing table far from the discharge port abuts against the end of the loading rack.

[0018] By adopting the above technical solution, the setting of the processing table plays a good supporting role for the motor end cover, enhancing the stability of the tumbling operation on the bearing chamber of the motor end cover.

[0019] Furthermore, a light sensor for monitoring the position of the motor end cover is fixed at a position on the loading rack close to the processing table.

[0020] By adopting the above technical solution, the setting of the light sensor monitors the motor end cover close to the processing table, and the monitoring result is transmitted to the control center of the device, so that the control center controls the clamping assembly to clamp the motor end cover under the tumbling assembly, and then performs tumbling operations through the tumbling assembly.

[0021] In summary, the present utility model has the following beneficial effects:

[0022] 1. In the present application, the loading assembly conveys the motor end cover to be tumbled into the machine body.

[0032] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application; obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0033] As Figure 1-7 shown, the embodiment of the present application discloses a barrel finishing device for the bearing chamber of a motor end cover, including a machine body 1 and a loading rack 2. Feed inlets 12 and discharge outlets 13 are respectively arranged on both sides of the machine body 1. One end of the loading rack 2 extends into the feed inlet 12 and is fixed to the machine body 1. A loading component 4 (implemented by an ordinary belt drive method) for conveying the motor end cover 3 to be barrel finished into the machine body 1 is arranged on the loading rack 2. A clamping component 5 for clamping the motor end cover 3 to be barrel finished and a barrel finishing component 6 for performing barrel finishing operations on the bearing chamber 31 inside the motor end cover 3 are arranged inside the machine body 1.

[0034] The feeding component 4 conveys the motor end cover 3 to be tumbled to the inside of the machine body 1. After reaching below the tumbling component 6, the clamping component 5 clamps the motor end cover 3 to be tumbled, and the tumbling component 6 can perform tumbling operation on the bearing chamber 31 of the motor end cover 3, which is beneficial to maintaining the perpendicularity and dimensional tolerance of the bearing chamber 31 within a suitable range.

[0035] A column 10 is fixed inside the machine body 1. The tumbling component 6 includes a power head 61 arranged on the column 10 and a tumbling tool 62 connected to the output end of the power head 61. The power head 61 is a power component that can both rotate and control the reciprocating movement of the component. After the power head 61 works, it can drive the tumbling tool 62 to rotate during the lifting process, so as to realize the tumbling operation on the bearing chamber 31 of the motor end cover 3.

[0036] A first mounting bracket 611 is fixedly sleeved on the output end of the power head 61. A pressing component 7 is arranged on the first mounting bracket 611. The pressing component 7 includes a guide rod 71 penetrating through and slidingly fitted with the bottom plate of the first mounting bracket 611, an annular pressing plate 72 fixed to the lower end of the guide rod 71, and a pressing spring 73 sleeved on the guide rod 71. The upper and lower ends of the pressing spring 73 are respectively fixed to the bottom of the bottom plate of the first mounting bracket 611 and the top of the annular pressing plate 72, and the annular pressing plate 72 is coaxially arranged with the tumbling tool 62. During the process of the output end of the power head 61 driving the tumbling tool 62 to lift and lower, the first mounting bracket 611, the guide rod 71, the annular pressing plate 72 and the pressing spring 73 lift and lower synchronously. After the annular pressing plate 72 presses the motor end cover 3, the stability of the bearing chamber 31 of the motor end cover 3 during the tumbling process is enhanced.

[0037] The clamping component 5 includes a longitudinal mounting seat 51 arranged inside the machine body 1, a longitudinal two-way lead screw 55 rotatably mounted on the longitudinal mounting seat 51, a longitudinal motor 52 arranged on the longitudinal mounting seat 51 and used to drive the longitudinal two-way lead screw 55 to rotate, a longitudinal sliding block 53 sleeved on the longitudinal two-way lead screw 55 and threadedly connected, and a clamping plate 54 arranged on the top of the longitudinal sliding block 53.

Two longitudinal sliding blocks 53 are provided and symmetrically distributed on the two sections of threads of the longitudinal two-way lead screw 55. The clamping plates 54 on both sides cooperate to clamp the motor end cover 3 to be tumbled.

[0038] After the longitudinal motor 52 works, it drives the longitudinal two-way lead screw 55 to rotate. Since the two longitudinal sliding blocks 53 are respectively threadedly connected to the two sections of threads of the longitudinal two-way lead screw 55, and the longitudinal sliding blocks 53 are slidably connected to the longitudinal mounting seat 51, the two longitudinal sliding blocks 53 approach or move away from each other, so that the clamping plates 54 on the two longitudinal sliding blocks 53 approach or move away from each other, so as to clamp the motor end cover 3 for the tumbling component 6 to perform tumbling operation.

[0039] A connecting seat 8 is fixed to the top of each longitudinal sliding block 53. Two sliding seats 81 are fixed to the top of the connecting seat 8. The two sliding seats 81 are respectively in sliding fit with both sides of the longitudinal mounting seat 51.

The slider is fixed to the bottom of the longitudinal mounting seat 51 to realize driving the longitudinal mounting seat 51 to reciprocate between the feed inlet 12 and the discharge outlet 13. After the motor end cover 3 is polished, the driving assembly 9 drives the longitudinal mounting seat 51 to move towards the side away from the feed inlet 12 until the discharge pushing plate 821 pushes the motor end cover 3 out of the discharge outlet 13. Subsequently, the driving assembly 9 drives the longitudinal mounting seat 51 to reset for the next polishing operation.

[0041] A position sensor 11 for monitoring whether there is a motor end cover 3 in the area directly opposite to the bottom of the polishing cutter 62 is fixed in the machine body 1. The setting of the position sensor 11 enables the device to monitor the position of the motor end cover 3 in real time, which is beneficial for the polishing assembly 6 to polish the motor end cover 3.

[0042] A discharge hopper 14 is fixed at the discharge outlet 13 of the machine body 1. A processing table 15 extending from the discharge outlet 13 to a position close to the feed inlet 12 is fixed in the machine body 1. One end of the processing table 15 away from the discharge outlet 13 abuts against the end of the loading rack 2. The setting of the processing table 15 plays a good supporting role for the motor end cover 3 and enhances the stability of polishing the bearing chamber 31 of the motor end cover 3.

After reaching under the polishing assembly 6, the clamping assembly 5 clamps the motor end cover 3 to be polished, and the polishing assembly 6 can polish the bearing chamber 31 of the motor end cover 3, which is beneficial to keeping the perpendicularity and dimensional tolerance of the bearing chamber 31 within a suitable range.
