The terms "first", "second", etc. in the specification and claims of this application or the above drawings are used to distinguish different objects and not to describe a specific order; the terms "inner", "outer", "left", "right" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0030] Reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0031] An embodiment of the present invention provides a polishing device for the outer shell in the production of a coaxial gear reducer, as Figure 1-10As shown in the figure, the shell polishing equipment for the production of coaxial gear reducers includes: a workbench 1 and a connecting rod 2 rotatably mounted on the workbench 1; a placement seat 3 detachably mounted on the connecting rod 2 for placing the reducer shell; a bracket 4 provided on one side of the placement seat 3, and a grinding wheel 7 for polishing the reducer shell is provided on the bracket 4; an electric telescopic rod 5 fixedly mounted on the bottom of the inner wall of the bracket 4; a group of rectangular seats 6 respectively rotatably mounted on the electric telescopic rod 5 and the top of the inner wall of the bracket 4, and the two rectangular seats 6 are respectively inserted into the two rotating shafts of the grinding wheel 7; a motor 8 mounted on the support plate of the bracket 4 for driving the grinding wheel 7 to rotate, and the motor 8 is fixedly connected to the rectangular seat 6 located on the bracket 4 by a coupling; a clamping mechanism provided on the placement seat 3 for fixing the reducer shell.

[0032] In this embodiment, during operation, the reducer shell is placed on the placement seat 3 and fixed by the clamping mechanism on the placement seat 3. The motor 8 drives the rectangular seat 6 to rotate, and then drives the grinding wheel 7 inserted on the two rectangular seats 6 to rotate to polish the reducer shell. During polishing, it can be used in combination with a vacuum cleaner to collect the iron filings generated during polishing. When the grinding wheel 7 needs to be replaced due to continuous wear, the electric telescopic rod 5 drives the rectangular seat 6 to slide down, so that the two rectangular seats 6 move away from each other relatively. At this time, the grinding wheel 7 can be removed for replacement; since the motor 8 drives the rectangular seat 6 to rotate and the electric telescopic rod 5 is rotatably connected to the rectangular seat 6, when the rectangular seat 6 and the grinding wheel 7 rotate, the electric telescopic rod 5 will not rotate synchronously. By driving the rectangular seat 6 to move through the electric telescopic rod 5, the rapid disassembly and assembly of the grinding wheel 7 are realized, greatly shortening the replacement time of the grinding wheel 7 and improving the production efficiency. By driving the rectangular seat 6 to rotate by the motor 8 and the electric telescopic rod 5 being rotatably connected to the rectangular seat 6, this design makes the electric telescopic rod 5 not rotate synchronously when the grinding wheel 7 rotates, ensuring the normal operation of the equipment, simplifying the structure at the same time, and reducing the difficulty of equipment maintenance.

[0033] In a further preferred embodiment of the present invention, the clamping mechanism includes: a connection groove opened at the top of the placement seat 3; a bidirectional screw 9 rotatably mounted in the connection groove; connection blocks 10 both threadedly sleeved on the bidirectional screw 9; arc-shaped clamping blocks 11 respectively fixedly mounted on the two connection blocks 10 for clamping and fixing the reducer shell.

[0034] In this embodiment, when it is necessary to fix the reducer housing, rotate the bidirectional screw 9. Due to the characteristics of the bidirectional screw 9, it drives the two connecting blocks 10 to move relative to each other along the bidirectional screw 9, and then drives the two arc-shaped clamping blocks 11 to move closer to each other, thereby clamping and fixing the reducer housing placed on the placing seat 3. Conversely, if it is necessary to remove the housing, rotate the bidirectional screw 9 in the reverse direction to make the two arc-shaped clamping blocks 11 move away from each other, and the housing can be loosened. By rotating the bidirectional screw 9 to drive the movement of the arc-shaped clamping blocks 11 to fix the reducer housing, the arc-shaped clamping blocks 11 can better fit the shape of the housing, providing a more stable clamping force, ensuring that the housing will not shake or shift during the polishing process, and guaranteeing the quality and accuracy of polishing. By simply rotating the bidirectional screw 9, the movement of the arc-shaped clamping blocks 11 can be realized, and then the fixing and loosening operations of the housing can be completed. The operation is simple and convenient, without the need for complex tools or steps, improving the efficiency of production operations.

[0035] In a further preferred embodiment of the present invention, an anti-slip pad is installed on the arc-shaped clamping block 11, and the anti-slip pad is used to increase the friction with the housing. The rotating shaft of the grinding wheel 7 is arranged in a rectangular shape.

[0036] In this embodiment, when the bidirectional screw 9 is rotated, it drives the connecting block 10 to drive the arc-shaped clamping block 11 to move, making the two arc-shaped clamping blocks 11 move closer to each other. The anti-slip pad is used to increase the friction with the reducer housing, thereby firmly clamping and fixing the housing. Through the anti-slip pad installed on the arc-shaped clamping block 11, the friction with the reducer housing is significantly increased, further enhancing the stability of clamping, effectively preventing the housing from shifting due to vibration or other reasons during the polishing process, ensuring that the polishing operation can be carried out stably and accurately, improving the polishing quality. By arranging the rotating shaft of the grinding wheel 7 in a rectangular shape and cooperating with the rectangular seat 6, when the motor 8 drives the rectangular seat 6 to rotate, the torque can be transmitted more effectively, making the rotation of the grinding wheel 7 more stable and reliable, reducing problems such as uneven polishing caused by unstable transmission, and ensuring the consistency of the polishing effect.

[0037] In a further preferred embodiment of the present invention, a fixing frame 12 is arranged on the workbench 1, the fixing frame 12 is fixedly connected to the support plate of the bracket 4, a group of hydraulic cylinders 13 are fixedly installed on the top of the workbench 1, a group of the hydraulic cylinders 13 are respectively located on one side of the fixing frame 12, and mounting blocks are fixedly installed on a group of the hydraulic cylinders 13, and a group of the mounting blocks are all fixedly connected to the fixing frame 12.

[0038] In this embodiment, during polishing, the hydraulic cylinder 13 is started. The hydraulic cylinder 13 drives the fixing frame 12 to move towards the placing seat 3 through the mounting block. Since the fixing frame 12 is fixedly connected to the support plate of the support 4, the support 4 is driven to move together, so that the grinding wheel 7 on the support 4 is closely attached to the reducer housing. After that, the motor 8 drives the rectangular seat 6 to rotate, driving the grinding wheel 7 to rotate, thereby polishing the reducer housing. By driving the fixing frame 12 and the support 4 to move through the hydraulic cylinder 13, the pressure between the grinding wheel 7 and the reducer housing can be accurately controlled, so as to adjust the polishing force according to different polishing requirements, obtain a better polishing effect, and meet the diversified production needs. The use of the hydraulic cylinder 13 makes the contact and separation operations between the grinding wheel 7 and the housing more flexible and convenient. When placing and removing the reducer housing, the grinding wheel 7 can be moved away to avoid interference, improving the convenience and safety of the operation.

[0039] In a further preferred embodiment of the present invention, a guiding groove is formed at the top of the workbench 1, a guiding rod 14 is fixedly installed in the guiding groove, a guiding block 15 is slidably sleeved on the guiding rod 14, and the guiding block 15 is fixedly connected to the fixing frame 12.

[0040] In this embodiment, when the fixing frame 12 moves, the guiding block 15 moves along the guiding rod 14. This guiding structure provides an accurate guiding effect for the movement of the fixing frame 12, ensuring that the grinding wheel 7 can accurately approach or move away from the reducer housing, making the contact position between the grinding wheel 7 and the housing more accurate during the polishing operation, improving the quality and precision of polishing. Through the cooperation of the guiding rod 14 and the guiding block 15, the vibration and position deviation of the fixing frame 12 caused by various factors during the movement can be effectively reduced, ensuring the smooth operation of the entire polishing equipment, and reducing the adverse effects on the polishing effect and equipment components caused by vibration.

[0041] In a further preferred embodiment of the present invention, a linkage mechanism for synchronously driving the grinding wheel 7 and the placing seat 3 to rotate is provided on the workbench 1. The linkage mechanism includes: a rectangular telescopic rod 16 rotatably installed on one side of the support plate; a set of bevel gears 17 respectively fixedly sleeved on the rotating shafts of the rectangular telescopic rod 16 and the rectangular seat 6, and the set of bevel gears 17 are meshed with each other; a linkage rod 18 rotatably installed on the workbench 1; a set of differential wheels 19 respectively fixedly sleeved on the top end of the linkage rod 18 and the other rotating shaft of the rectangular telescopic rod 16, and the set of differential wheels 19 are meshed with each other; differential sprockets 20 respectively fixedly sleeved on the linkage rod 18 and the bottom end of the connecting rod 2, and a chain 21 is sleeved on the two differential sprockets 20.

[0042] In this embodiment, when the motor 8 drives the rectangular seat 6 to rotate, since a bevel gear 17 is fixedly sleeved on the rotating shaft of the rectangular seat 6 and this bevel gear 17 meshes with the bevel gear 17 on the rectangular telescopic rod 16, the rotational force will be transmitted to the rectangular telescopic rod 16 through the bevel gear 17, causing the rectangular telescopic rod 16 to rotate; a differential wheel 19 is fixedly sleeved on another rotating shaft of the rectangular telescopic rod 16, and this differential wheel 19 meshes with the differential wheel 19 at the top of the linkage rod 18, thereby transmitting the rotational force to the linkage rod 18, causing the linkage rod 18 to rotate. When the linkage rod 18 rotates, it drives the differential sprocket 20 thereon to rotate, and through the chain 21, the synchronous rotation of the linkage rod 18 and the connecting rod 2 is achieved, so that the placement seat 3 rotates. Additionally, due to the arrangement of the bevel gear 17 and the differential wheel 19, the grinding wheel 7 and the placement seat 3 rotate relative to each other; at the same time, through the reasonable design of the differential sprocket 20 and the differential wheel 19, the placement seat 3 rotates at a low speed. Through the ingenious cooperation of the linkage mechanism with the bevel gear 17, the differential wheel 19, the differential sprocket 20, and the chain 21, the synchronous rotation of the grinding wheel 7 and the placement seat 3 is realized. This synchronous rotation can enable the grinding wheel 7 to polish the reducer housing more evenly, improving the polishing quality and efficiency, and avoiding the problem of uneven polishing caused by the asynchronous rotation of the two. Through the arrangement of the bevel gear 17 and the differential wheel 19, the grinding wheel 7 and the placement seat 3 rotate relative to each other, and this relative rotation can produce a better polishing effect. Through the frictional action in different directions, the defects and unevenness on the surface of the housing can be more effectively removed, further improving the polishing quality.

[0043] In a further preferred embodiment of the present invention, an L-shaped plate 22 is fixedly installed at the bottom of the workbench 1. The L-shaped plate 22 is located on one side of the linkage rod 18. A protective cover 23 for protecting the chain 21 is provided at the bottom of the workbench 1. The protective cover 23 covers the differential sprocket 20 and the chain 21. One side of the protective cover 23 is in contact with the L-shaped plate 22. A screwing block 24 for fixing the protective cover 23 is threadedly installed at the bottom of the L-shaped plate 22, and the screwing block 24 is in close contact with the bottom of the protective cover 23.

[0044] In this embodiment, a protective cover 23 is placed over the differential sprocket 20 and the chain 21, with one side of the protective cover 23 contacting the L-shaped plate 22 fixed to the bottom of the workbench 1. Then, by rotating the screw block 24 threadedly installed at the bottom of the L-shaped plate 22, the screw block 24 moves upward and closely contacts the bottom of the protective cover 23, thereby fixing the protective cover 23 to the bottom of the workbench 1 to protect the differential sprocket 20 and the chain 21. When maintenance or repair of the differential sprocket 20 and the chain 21 is required, the screw block 24 is rotated in the reverse direction to disengage it from the bottom of the protective cover 23, and then the protective cover 23 can be removed. By covering the differential sprocket 20 and the chain 21 with the protective cover 23, it can effectively prevent the operator from accidentally contacting the rotating differential sprocket 20 and chain 21 during the operation of the equipment, avoid safety accidents, and ensure the personal safety of the operator.

[0045] In a further preferred embodiment of the present invention, an adapter plate 29 is fixedly installed at the bottom of the workbench 1, and an L-shaped rod 30 is fixedly installed on one side of the protective cover 23. The L-shaped rod 30 slidably penetrates through the adapter plate 29.

[0046] In this embodiment, when installing the protective cover 23, the protective cover 23 is placed over the differential sprocket 20 and the chain 21, and at the same time, the L-shaped rod 30 is inserted into the adapter plate 29. The cooperation between the L-shaped rod 30 and the adapter plate 29 is used to preliminarily position the protective cover 23, so that the protective cover 23 maintains a relatively stable position in the horizontal direction. Then, through the cooperation of the previously mentioned L-shaped plate 22 and the screw block 24, the screw block 24 is rotated to closely contact the bottom of the protective cover 23, thereby firmly fixing the protective cover 23 to the bottom of the workbench 1. When the protective cover 23 needs to be removed, first rotate the screw block 24 in the reverse direction to disengage it from the bottom of the protective cover 23, and then pull out the L-shaped rod 30 from the adapter plate 29, and the protective cover 23 can be removed. The cooperation between the L-shaped rod 30 and the adapter plate 29 provides accurate positioning for the installation of the protective cover 23, ensuring that the protective cover 23 can accurately cover the differential sprocket 20 and the chain 21, avoiding problems such as poor protection effect or interference with other components caused by installation position deviation, and improving the installation accuracy and efficiency.

[0047] In a further preferred embodiment of the present invention, a protective shell 25 is fixedly installed on the top of the workbench 1. The protective shell 25 covers the linkage rod 18. On one side of the fixed frame 12, a U-shaped frame 26 is fixedly installed. The U-shaped frame 26 covers the protective shell 25.

[0048] In this embodiment, during the operation of the device, the linkage rod 18 drives the placement seat 3 to rotate through the linkage mechanism. The protective shell 25 wraps the linkage rod 18, and the U-shaped frame 26 further covers the protective shell 25 to form a protective structure. Since there is a transmission relationship between the linkage rod 18 and the rectangular telescopic rod 16 (the linkage rod 18 is connected to the rectangular telescopic rod 16 through the differential wheel 19), actually the protective shell 25 and the U-shaped frame 26 also indirectly play a certain protective role for transmission components such as the rectangular telescopic rod 16, preventing operators from touching these rotating or moving components when the device is operating.

[0049] In a further preferred embodiment of the present invention, a chute is provided in the U-shaped frame 26, a slide rod 27 is fixedly installed in the chute, a slider 28 is slidably sleeved on the slide rod 27, and the slider 28 is fixedly connected to the protective shell 25.

[0050] In this embodiment, the length of the rectangular telescopic rod 16 can be automatically adjusted as the fixed frame 12 moves, ensuring that the meshing relationship between transmission components such as the bevel gear 17 and the differential wheel 19 is always in a good state, effectively avoiding problems such as misalignment and slipping of transmission components caused by the movement of the fixed frame 12, guaranteeing the stability and reliability of the transmission of the linkage mechanism, and further ensuring the normal operation of the synchronous and relative rotation of the grinding wheel 7 and the placement seat 3, improving the quality and efficiency of the polishing operation. The sliding fit between the slide rod 27 and the slider 28 provides accurate guidance for the movement of the U-shaped frame 26, so that the U-shaped frame 26 will not shake or deviate during the process of following the fixed frame 12 moving, ensuring that the U-shaped frame 26 always accurately covers the protective shell 25 and continuously providing reliable protection for components such as the linkage rod 18.

[0051] In order to further improve the use effect of the present device, in addition to the above-mentioned solutions, this solution also has the following embodiments:

[0052] In another embodiment of the present invention, a support wheel 31 for supporting the placement seat 3 is fixedly installed on the top of the workbench 1. The support wheel 31 is in contact with the bottom of the placement seat 3. A limiting mechanism for preventing the bidirectional screw 9 from retracting is provided on one side of the placement seat 3. The limiting mechanism includes: a rotating rod 32 fixedly installed at one end of the bidirectional screw 9; a limiting gear 33 fixedly sleeved on the rotating rod 32; a spring 34 installed on one side of the placement seat 3; a clamping plate 35 rotatably installed on one side of the placement seat 3 for preventing the limiting gear 33 from retracting. The clamping plate 35 is fixedly connected to the top end of the spring 34, and the clamping plate 35 is engaged with the teeth of the limiting gear 33.

[0053] In this embodiment, the support wheel 31 provides a supporting effect for the placement seat 3, enabling the placement seat 3 to be stably placed on the workbench 1 and achieve rotation;

[0054] When fixing the outer shell, the operator drives the bidirectional screw 9 to rotate by rotating the rotating rod 32, thereby realizing the clamping and fixing operation of the outer shell. At the same time, during the rotation of the rotating rod 32, the clamping plate 35 installed on one side of the placing seat 3 always closely adheres to the limiting gear 33 under the action of the spring 34. When the rotating rod 32 stops rotating, the elastic force of the spring 34 will snap the clamping plate 35 into the teeth of the limiting gear 33. Through the clamping connection between the clamping plate 35 and the teeth of the limiting gear 33, the limiting gear 33 (i.e., the rotating rod 32 and the bidirectional screw 9) is prevented from retracting, thereby ensuring that the bidirectional screw 9 maintains the current clamping state, enabling the outer shell to be stably fixed on the placing seat 3. Through the clamping connection between the clamping plate 35 and the limiting gear 33, the retraction phenomenon of the bidirectional screw 9 after the outer shell is fixed is effectively prevented, ensuring that the outer shell is always in a stable clamping state, avoiding the loosening of the outer shell caused by the retraction of the bidirectional screw 9, and guaranteeing the smooth progress of the polishing process.

[0055] In another embodiment of the present invention, a cylinder 36 is fixedly installed on one side of the placing seat 3. A pulling rope 37 is sleeved on the cylinder 36. One end of the pulling rope 37 is fixedly connected to the clamping plate 35. A hanging ring 38 is fixedly installed on the pulling rope 37. A hanging rod 39 is fixedly installed on one side of the placing seat 3. The hanging rod 39 is located on one side of the hanging ring 38.

[0056] In this embodiment, when the bidirectional screw 9 needs to be reset, the operator hangs the hanging ring 38 on the hanging rod 39. Since one end of the pulling rope 37 is connected to the clamping plate 35, the pulling rope 37 will be subjected to a pulling force at this time, and then the clamping plate 35 is pulled to rotate to the left, so that the clamping plate 35 is away from the limiting gear 33, releasing the clamping effect of the clamping plate 35 on the limiting gear 33. After that, the operator can reversely rotate the bidirectional screw 9 to realize the reset operation of the bidirectional screw 9. By setting the cylinder 36, the pulling rope 37, the hanging ring 38 and the hanging rod 39, a convenient operation method is provided for the reset of the bidirectional screw 9. The operator only needs to simply hang the hanging ring 38 on the hanging rod 39 to easily release the restriction of the limiting mechanism on the bidirectional screw 9 without complex operation steps, greatly improving the work efficiency.

[0057] In summary, compared with the related technology, this polishing equipment drives the grinding wheel to rotate and polish by the motor driving the rectangular seat, and the electric telescopic rod is rotatably connected to the rectangular seat to realize the quick disassembly and assembly of the grinding wheel, having the advantages of short grinding wheel replacement time, high production efficiency and low maintenance difficulty.
