Description

Technical Field

[0001] This utility model relates to the field of plastic parts polishing technology, and in particular to a plastic parts surface polishing device. Background Technology

[0002] During the production process, plastic parts need to be polished to ensure that the surface of the plastic products meets the requirements for use.

[0003] For example, CN216633833U discloses a plastic parts grinding device, including an installation platform, a water storage cavity at the upper end of the installation platform, a dust cover installed at the upper end of the installation platform, electric nozzles that are evenly distributed and communicate with the water storage cavity are fixedly connected to the inner top wall of the dust cover, and a grinding mechanism that is fixedly connected to the installation platform is installed inside the dust cover.

[0004] However, in the existing technology, different plastic parts have different shapes and structures. Some plastic parts have depressions or protrusions on their surfaces. When traditional grinding mechanisms grind plastic parts, their position adjustment and angle adjustment are limited, which can easily lead to the inability to grind special-shaped parts of the plastic parts, directly affecting the grinding quality of the plastic parts. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the angle adjustment of traditional grinding mechanisms in the prior art is limited when grinding plastic parts, and to propose a plastic part surface grinding device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a plastic part surface polishing device, including a support platform, a positioning cylinder fixedly installed on the top of the support platform, a rotating cylinder rotatably installed on the outer wall of the positioning cylinder, a support frame rotatably connected to the top of the rotating cylinder, and a polishing machine fixedly installed on the top of the support frame.

[0007] A first gear is fixedly installed at the bottom of the rotating drum. A first servo motor and a second servo motor are fixedly installed at both ends inside the support platform. The first servo motor and the second servo motor are symmetrically distributed on both sides of the rotating drum. A connecting gear is fixedly installed on the output shaft of the first servo motor and the output shaft of the second servo motor. One of the connecting gears is meshed with the first gear.

[0008] Preferably, a second gear is rotatably mounted on the outer wall of the rotating drum, and the second gear meshes with a connecting gear on the output shaft of the second servo motor.

[0009] Preferably, an extension rod is fixedly installed on the top of the rotating drum, and the support frame is rotatably mounted on the extension rod.

[0010] Preferably, a first bevel gear is fixedly mounted on the upper surface of the second gear.

[0011] Preferably, a second bevel gear is fixedly installed on the inner side wall of the support frame, and the second bevel gear meshes with the first bevel gear.

[0012] Preferably, the positioning cylinder has an internal cavity.

[0013] Preferably, a guide rod is fixedly installed on the upper surface of the positioning cylinder, and a limit block is slidably connected to the inner side wall of the guide rod.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In this utility model, the position of the rubber part is determined by the positioning cylinder, and a rotating cylinder is set on the outer wall of the positioning cylinder. During the grinding process, the rotating cylinder can directly drive the grinding machine to rotate, thereby changing the contact part between the rubber part and the grinding machine. This solves the limitation of the traditional grinding machine position adjustment and allows special-shaped plastic parts to be fully ground.

[0016] 2. In this utility model, by setting a second bevel gear on the support frame for meshing with the first bevel gear, the second gear drives the first bevel gear during use, thereby driving the support frame to rotate around the extension rod. This allows for direct adjustment of the contact angle between the grinder and the plastic part, thus solving the problem of inconvenient angle adjustment. Attached Figure Description

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides a plastic part surface polishing device, including a support platform 1, a positioning cylinder 16 fixedly installed on the top of the support platform 1, a rotating cylinder 2 rotatably installed on the outer wall of the positioning cylinder 16, a support frame 4 rotatably connected to the top of the rotating cylinder 2, and a polishing machine 5 fixedly installed on the top of the support frame 4.

[0025] A first gear 9 is fixedly installed at the bottom of the rotating drum 2. A first servo motor 6 and a second servo motor 7 are fixedly installed at both ends inside the support platform 1. The first servo motor 6 and the second servo motor 7 are symmetrically distributed on both sides of the rotating drum 2. A connecting gear 8 is fixedly installed on the output shaft of the first servo motor 6 and the output shaft of the second servo motor 7. One of the connecting gears 8 is meshed with the first gear 9.

[0026] The positioning cylinder 16 has a cavity 3 inside, and a guide rod 14 is fixedly installed on the upper surface of the positioning cylinder 16. A limit block 15 is slidably connected to the inner side wall of the guide rod 14.

[0027] The specific settings and functions of this embodiment are described below. The first servo motor 6 and the second servo motor 7 are symmetrically distributed on both sides of the rotating drum 2. Their output shafts rotate in the same direction. When grinding, the rubber part is placed on the top of the positioning cylinder 16, and the limiting block 15 is moved along the direction of the guide rod 14 to determine the clamping of the rubber part and the position of the rubber part. The rubber part can be located at any position on the top of the positioning cylinder 16, while the grinding machine 5 is located at the eccentric position of the positioning cylinder 16 to facilitate the adjustment of the grinding part. After the position of the rubber part is determined, the grinding machine 5 on the support frame 4 is started to grind the surface of the rubber part.

[0028] During the grinding process, the operation of the first servo motor 6 can drive the first gear 9 through the connecting gear 8, thereby directly driving the rotating drum 2. Since the support frame 4 is installed on the rotating drum 2, the rotation of the rotating drum 2 will directly drive the support frame 4, thereby driving the grinding machine 5 to rotate around the axis of the positioning cylinder 16, allowing the grinding machine 5 to contact various parts of the rubber part.

[0029] Example 2: Figure 2 and Figure 3 As shown, a second gear 10 is rotatably mounted on the outer wall of the rotating drum 2. The second gear 10 meshes with the connecting gear 8 on the output shaft of the second servo motor 7. An extension rod 13 is fixedly mounted on the top of the rotating drum 2. A support frame 4 is rotatably mounted on the extension rod 13. A first bevel gear 11 is fixedly mounted on the upper surface of the second gear 10. A second bevel gear 12 is fixedly mounted on the inner side wall of the support frame 4. The second bevel gear 12 meshes with the first bevel gear 11.

[0030] The overall effect of this embodiment is that the second gear 10 is installed on the outer wall of the rotating drum 2, and its upper surface is provided with a first bevel gear 11 that meshes with the second bevel gear 12 on the inner side wall of the support frame 4. In use, the second servo motor 7 meshes with the second gear 10 through the connecting gear 8 to drive the first bevel gear 11 to rotate, thereby forcing the support frame 4 to rotate around the extension rod 13 and adjusting the contact angle between the grinding machine 5 and the rubber part.

[0031] The usage method and working principle of this device are as follows: When grinding, the rubber part is placed on the top of the positioning cylinder 16 and fixed with the limiting block 15. The grinding machine 5 is located at the eccentric position of the positioning cylinder 16 to facilitate the adjustment of the grinding position. After determining the position of the rubber part, the grinding machine 5 on the support frame 4 is started to grind the surface of the rubber part.

[0032] During the grinding process, the first servo motor 6 and the second servo motor 7 are started, and the output shafts of the first servo motor 6 and the second servo motor 7 are kept at the same rotation speed. The first gear 9 is driven by the connecting gear 8, which drives the rotating drum 2 to rotate. This makes the grinding machine 5 rotate around the axis of the positioning cylinder 16, allowing the grinding machine 5 to contact various parts of the rubber part. During this process, the second bevel gear 12 pushes the first bevel gear 11 to ensure that the second gear 10 adapts to the rotation of the connecting gear 8 on the output shaft of the second servo motor 7, so that the support frame 4 does not rotate.

[0033] When it is necessary to adjust the grinding angle, the speed of the output shaft of the second servo motor 7 is controlled to be higher or lower than that of the first servo motor 6, so that a speed difference is generated between the first gear 9 and the second gear 10. At this time, the connecting gear 8 on the output shaft of the second servo motor 7 will push the second gear 10 on the outer wall of the rotating drum 2. The second gear 10 meshes with the second bevel gear 12 through the first bevel gear 11, so that the support frame 4 rotates around the extension rod 13, thereby adjusting the contact angle between the grinding machine 5 and the rubber part.

[0034] 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.
