Description

Technical Field

[0001] This utility model relates to the field of bell-shaped shell polishing technology, and in particular to a bell-shaped shell rotary polishing device. Background Technology

[0002] Bell-shaped shell rotary polishing equipment is mainly used for surface polishing of workpieces such as bell-shaped shells, aiming to improve the smoothness and surface quality of the workpieces. This equipment usually uses rotation to bring the workpiece into contact with the polishing medium, thereby achieving a uniform and efficient polishing effect. It is widely used in fields such as machinery manufacturing and jewelry processing.

[0003] However, in actual use, the following shortcomings still exist. For example, existing bell-shaped shell rotary polishing devices cannot stably clamp bell-shaped shells of different specifications and cannot avoid damage during the clamping process. Unstable clamping makes the bell-shaped shell prone to displacement or shaking during polishing, causing the polishing tool to fail to process the surface of the bell-shaped shell according to the predetermined trajectory and parameters. This affects key quality indicators such as the dimensional accuracy, shape accuracy, and surface roughness of the bell-shaped shell. Insecure clamping can cause relative sliding or friction between the bell-shaped shell and the fixture, resulting in scratches, abrasions, and other defects on the surface of the bell-shaped shell. These surface damages not only affect the appearance quality of the bell-shaped shell but may also reduce its corrosion resistance and wear resistance, shortening its service life.

[0004] Therefore, this utility model proposes a bell-shaped shell rotary polishing device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a bell-shaped shell rotary polishing device.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a bell-shaped shell rotary polishing device, comprising:

[0007] Base;

[0008] A polishing assembly, comprising a support frame fixed to one side of a base, a first drive motor mounted on the top of the support frame, and a polishing head fixed to the output end of the first drive motor;

[0009] The clamping assembly includes a support base mounted on a base, a second drive motor mounted on the bottom of the support base, a rotating block fixed to the output end of the second drive motor, a rotating rod rotatably connected to the rotating block, a clamping block rotatably connected to the side of the rotating rod away from the rotating block, a rubber pad fixed to the clamping block, and a placement groove provided on the support base.

[0010] Furthermore, a limiting block is fixed at the bottom of the clamping block, and a limiting groove is formed on the side of the support base near the limiting block, with the limiting block slidably connected in the limiting groove.

[0011] The beneficial effects of adopting the above-mentioned further solution are: the limiting block is fixed at the bottom of the clamping block and slidably connected with the limiting groove on the support base. When the clamping block moves outward under the drive of the rotating rod, the limiting block moves along the limiting groove, ensuring that the clamping movement is carried out along the predetermined trajectory, preventing deviation, enhancing clamping stability, and avoiding workpiece displacement or clamping failure due to uneven force.

[0012] Furthermore, a lifting and rotating assembly is provided on the top of the base, the lifting and rotating assembly including a support plate fixed to one side of the base.

[0013] The beneficial effect of adopting the above-mentioned further solution is that the support plate is fixed on the base, and the third transmission motor is installed on the support plate to drive the first transmission wheel to rotate as a power source.

[0014] Furthermore, a third drive motor is mounted on the support plate, and a first drive wheel is fixed to the output end of the third drive motor. A belt is provided on the first drive wheel.

[0015] The beneficial effect of adopting the above-mentioned further solution is that after the motor starts, it drives the first transmission wheel to rotate through the output shaft, and then transmits power through the belt.

[0016] Furthermore, a second drive wheel is provided on the belt, and the second drive wheel is rotatably connected to the top of the base.

[0017] The beneficial effect of adopting the above-mentioned further scheme is that the first transmission wheel is driven to rotate by the third transmission motor, and drives the second transmission wheel to rotate synchronously through the belt.

[0018] Furthermore, a hydraulic push rod is mounted on the top of the second transmission wheel, and a bracket is fixed to the output end of the hydraulic push rod, with the support seat fixed to the top of the bracket.

[0019] The beneficial effects of adopting the above-mentioned further solution are: the hydraulic push rod is fixed on the top of the second transmission wheel, and its output end is connected to the bracket. When the hydraulic system is started, the hydraulic push rod extends and retracts, driving the bracket to move up and down, thereby adjusting the height of the support seat, providing stable vertical movement, and ensuring the precise adjustment of the workpiece position during the polishing process.

[0020] Furthermore, a telescopic rod is fixed to the second transmission wheel, and the other end of the telescopic rod is fixed to the bracket.

[0021] The beneficial effects of adopting the above-mentioned further solution are: one end of the telescopic rod is fixed on the second transmission wheel, and the other end is connected to the bracket. When the hydraulic push rod is raised and lowered, the telescopic rod extends and retracts accordingly, providing additional support, preventing the bracket from swaying, ensuring a smooth lifting process, avoiding positional deviation due to load changes, and improving processing accuracy and equipment reliability.

[0022] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0023] In this invention, when polishing a bell-shaped shell, the bell-shaped shell is first placed in the placement groove of the support base, ensuring its initial position is centered. After the second drive motor is started, it drives the rotating block to rotate. The rotation of the rotating rod drives the clamping block to move synchronously. The rubber pad is tightly attached to the surface of the bell-shaped shell, thereby achieving stable clamping of the bell-shaped shell. The rubber pad not only increases the friction and prevents the bell-shaped shell from sliding during processing, but also avoids damage to the bell-shaped shell by the clamping block. It is suitable for workpieces of different sizes. Subsequently, the first drive motor is started, causing the polishing head to rotate at high speed to polish the bell-shaped shell. Throughout the polishing process, the clamping block always stably clamps the bell-shaped shell, ensuring the smooth progress of the polishing operation. Attached Figure Description

[0034] 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.

[0035] like Figures 1-4 As shown, this embodiment provides a technical solution: a bell-shaped shell rotary polishing device, comprising:

[0036] Base 1;

[0037] Polishing assembly 2 includes a support frame 21 fixed to one side of the base 1, a first drive motor 22 is mounted on the top of the support frame 21, and a polishing head 23 is fixed to the output end of the first drive motor 22.

[0038] The clamping assembly 3 includes a support base 31 mounted on the base 1. A second drive motor 32 is mounted on the bottom of the support base 31. A rotating block 33 is fixed to the output end of the second drive motor 32. A rotating rod 34 is rotatably connected to the rotating block 33. A clamping block 35 is rotatably connected to the side of the rotating rod 34 away from the rotating block 33. A rubber pad 36 is fixed to the clamping block 35. A placement groove 39 is provided on the support base 31. When polishing the bell-shaped shell, the bell-shaped shell is first accurately placed in the placement groove 39 of the support base 31. Then, the second drive motor 32 is started, driving the rotating block 33 to rotate. The rotation of the rotating block 33... The rotating rod 34 moves synchronously, causing the clamping block 35 to move towards the bell-shaped shell. The rubber pad 36 on the clamping block 35 is in close contact with the surface of the bell-shaped shell, which not only increases the friction and effectively prevents the bell-shaped shell from sliding during processing, but also avoids damage to the surface of the bell-shaped shell caused by the clamping block 35. At the same time, it can adapt to bell-shaped shells of different sizes. During this process, the limiting block 37 at the bottom of the clamping block 35 slides along the upper limit groove 38 of the support base 31, limiting the movement trajectory of the clamping block 35 and further ensuring the stability of clamping. After the bell-shaped shell is clamped, the first drive motor 22 starts, driving the polishing head 23 to rotate at high speed and start polishing the bell-shaped shell.

[0039] The above solutions also have the problem that, when the bell-shaped shell is being polished, it cannot be stably raised, lowered, or rotated after being fixed. Figure 1 as well as Figures 3-4As shown: A limiting block 37 is fixed at the bottom of the clamping block 35. A limiting groove 38 is opened on the side of the support base 31 near the limiting block 37. The limiting block 37 is slidably connected in the limiting groove 38. The limiting block 37 is fixed at the bottom of the clamping block 35 and slidably connected with the limiting groove 38 on the support base 31. When the clamping block 35 moves outward under the drive of the rotating rod 34, the limiting block 37 moves along the limiting groove 38 to ensure that the clamping movement is carried out along the predetermined trajectory, prevent deflection, enhance clamping stability, and avoid workpiece displacement or clamping failure due to uneven force.

[0040] like Figure 1 as well as Figure 5 As shown, a lifting and rotating assembly 4 is provided on the top of the base 1. The lifting and rotating assembly 4 includes a support plate 41 fixed to one side of the base 1. The support plate 41 is fixed on the base 1. A third drive motor 42 is mounted on the support plate 41 and serves as a power source to drive the first drive wheel 43 to rotate. The third drive motor 42 is mounted on the support plate 41, and the first drive wheel 43 is fixed to the output end of the third drive motor 42. A belt 44 is provided on the first drive wheel 43. After the motor starts, it drives the first drive wheel 43 to rotate through the output shaft, and then transmits power through the belt 44. A second drive wheel 45 is provided on the belt 44. The second drive wheel 45 is rotatably connected to the top of the base 1. The first drive wheel 43 is driven to rotate by the third drive motor 42, and drives the second drive wheel 45 to rotate synchronously through the belt 44. A hydraulic system is installed on the top of the second drive wheel 45. A hydraulic push rod 46 is attached to a bracket 48 at its output end. A support seat 31 is fixed to the top of the bracket 48. The hydraulic push rod 46 is fixed to the top of the second transmission wheel 45, and its output end is connected to the bracket 48. When the hydraulic system is started, the hydraulic push rod 46 extends and retracts, causing the bracket 48 to move up and down, thereby adjusting the height of the support seat 31 and providing stable vertical movement to ensure accurate adjustment of the workpiece position during polishing. A telescopic rod 47 is fixed to the second transmission wheel 45, and the other end of the telescopic rod 47 is fixed to the bracket 48. When the hydraulic push rod 46 rises and falls, the telescopic rod 47 extends and retracts accordingly, providing additional support, preventing the bracket 48 from swaying, ensuring a smooth lifting process, avoiding positional shifts due to load changes, and improving processing accuracy and equipment reliability.

[0041] like Figures 1-5As shown, when performing bell-shaped shell polishing, the bell-shaped shell is first accurately placed into the placement groove 39 of the support base 31. Then, the second drive motor 32 is started, driving the rotating block 33 to rotate. The rotating block 33 drives the rotating rod 34 to move, causing the clamping block 35 to move closer to the bell-shaped shell. The rubber pad 36 on the clamping block 35 fits tightly against the bell-shaped shell, increasing friction and preventing the bell-shaped shell from slipping during processing. This also prevents the clamping block 35 from damaging the bell-shaped shell and adapts to bell-shaped shells of different sizes. During this process, the limiting block 37 at the bottom of the clamping block 35 slides along the limiting groove 38 on the support base 31, regulating the movement trajectory of the clamping block 35 and further stabilizing the clamping effect. After clamping is complete, the first drive motor 22 is started, driving the polishing head 23 to rotate at high speed, beginning the polishing of the bell-shaped shell. Polishing is performed simultaneously. The lifting and rotating assembly 4 functions, and the third drive motor 42, mounted on the support plate 41, drives the first drive wheel 43 to rotate. A belt 44 causes the second drive wheel 45 to rotate synchronously. The hydraulic push rod 46 on top of the second drive wheel 45 extends and retracts under the action of the hydraulic system, moving the bracket 48 up and down to adjust the height of the support base 31, ensuring comprehensive polishing of the bell-shaped shell surface. A telescopic rod 47 fixed on the second drive wheel 45, connected at one end to the bracket 48, extends and retracts with the hydraulic push rod 46 as it rises and falls, assisting in supporting the bracket 48, preventing it from swaying, and ensuring the stability of the support base 31. All components cooperate, and the clamping block 35 continuously and stably clamps the bell-shaped shell, achieving efficient and high-precision polishing of the bell-shaped shell.

[0042] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
