Description

Technical Field

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

[0002] Plastic bases are a type of general-purpose component widely used in various fields. Their uses and designs vary depending on the specific application scenarios and requirements. During the production process, plastic bases also require surface polishing.

[0003] As described in announcement number CN220902830U, a plastic base surface grinding mechanism includes a mounting base, a fixedly connected column and support plate, a driving device, and an adjusting device. The driving device includes a fixedly connected stabilizing column and a grinding disc, and a driving motor mounted on the support plate. The adjusting device includes a fixedly connected lifting cylinder and a rotating cylinder, a fixedly connected workpiece placement table and a stabilizing cylinder, and positioning components evenly distributed within the workpiece placement table. The positioning components include a connector, a positioning plate, and a telescopic spring. The connector is mounted on the outer surface of the stabilizing cylinder. When the driving motor operates, the grinding disc rotates, achieving automatic grinding of the surface of small-diameter disc plastic bases. When the lifting cylinder operates, the workpiece placement table moves upward, and the large-diameter grinding disc grinds multiple evenly distributed small-diameter disc plastic base products, providing the function of automatically grinding a certain number of small-diameter products.

[0004] This patent can automatically polish several small-diameter products. However, existing devices require spring force to clamp and fix the base when polishing. This clamping method can lead to fatigue or deformation during polishing, resulting in a decrease or instability in clamping force, which affects the polishing effect.

[0005] Therefore, we propose a novel plastic base surface polishing mechanism. Utility Model Content

[0006] The purpose of this invention is to solve the problem that existing devices require spring force to clamp and fix the base during grinding. This clamping method can lead to fatigue or deformation during grinding, resulting in a decrease or instability in clamping force, which in turn affects the grinding effect.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a plastic base surface polishing mechanism, including an operating table, a movable clamping assembly provided on one side of the operating table, the movable clamping assembly including a servo motor, a first gear connected to the output end of the servo motor, a second gear connected to the front end of two sets of the first gears, a connecting rod inserted inside the second gear, a third gear connected to both sides of the connecting rod, a fourth gear connected to the front end of each set of the third gears, a bidirectional screw fixedly connected to the front end of each set of the third gears, a bearing connected to the front end of each set of the bidirectional screws, two sets of moving blocks symmetrically connected to the surface of the bidirectional screws, each set of moving blocks having a threaded hole inside, and a moving plate connected to the top of every two sets of moving blocks.

[0008] Furthermore, a support frame is connected to the top of the operating table, and two sets of electric push rods are inserted into the top of the support frame.

[0009] Furthermore, the output ends of the two sets of electric push rods are connected to lifting plates, and a grinding motor is connected to the top center of the lifting plates. The output end of the grinding motor is connected to a grinding disc.

[0010] Furthermore, the servo motor is electrically connected to an external power source via a control switch, and the output end of the servo motor is fixedly connected to the first gear.

[0011] Furthermore, the first gear meshes with the second gear, the third gear meshes with the fourth gear, and the bidirectional screw is threadedly connected to the moving block through a threaded hole.

[0012] Furthermore, a fixing clamping assembly is provided on the inner side of the movable plate, the fixing clamping assembly including a slot, the slot being formed inside the movable plate.

[0013] Furthermore, a plug is inserted into the slot, a clamp is connected to one side of the plug, a handle is connected to the top of the movable plate, and two sets of magnetic plug rods are connected to the bottom of the handle.

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

[0015] 1. In this utility model, when it is necessary to polish the plastic base, the servo motor can be turned on to drive the first gear to rotate, thereby driving the two sets of bidirectional screws to rotate simultaneously through gear meshing. While the bidirectional screws are rotating, they will drive the two sets of fixed clamping components to clamp and fix the plastic base. Then the polishing motor can be started to polish the base, avoiding the problem that the spring clamping method is prone to causing the clamping force to decrease or become unstable, thus affecting the polishing effect.

[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, such as Figure 1 - Figure 3As shown, this utility model provides a plastic base surface polishing mechanism, including an operating table 1. A movable clamping assembly 7 is provided on one side of the operating table 1. The movable clamping assembly 7 includes a servo motor 701. The output end of the servo motor 701 is connected to a first gear 702. The front ends of the two sets of first gears 702 are connected to second gears 703. A connecting rod 704 is inserted into the inside of the second gear 703. Third gears 705 are connected to both sides of the connecting rod 704. The front ends of the two sets of third gears 705 are connected to fourth gears 706. The front ends of the two sets of third gears 705 are fixedly connected to bidirectional screws 707. The front ends of the two sets of bidirectional screws 707 are connected to bearings 708. Two sets of moving blocks 709 are symmetrically connected to the surface of the bidirectional screws 707. Each set of moving blocks 709... Each of the 09 has a threaded hole 710 inside. The top of each pair of moving blocks 709 is connected to a moving plate 711. The top of the operating table 1 is connected to a support frame 2. The top of the support frame 2 is inserted with two sets of electric push rods 3. The output ends of the two sets of electric push rods 3 are connected to a lifting plate 4. The top center of the lifting plate 4 is connected to a grinding motor 5. The output end of the grinding motor 5 is connected to a grinding disc 6. The servo motor 701 is electrically connected to an external power supply through a control switch. The output end of the servo motor 701 is fixedly connected to the first gear 702. The first gear 702 meshes with the second gear 703. The third gear 705 and the fourth gear 706 are meshed. The bidirectional screw 707 is threadedly connected to the moving block 709 through the threaded hole 710.

[0025] The overall effect of Embodiment 1 is that when polishing the surface of the plastic base, the base to be polished can be placed on the surface of the operating table 1. Then, the forward rotation function of the servo motor 701 can be turned on by the control switch. When the servo motor 701 rotates forward, it will also drive the first gear 702 to rotate, so that the first gear 702 can mesh with the second gear 703 and rotate, thereby driving the connecting rod 704 to rotate forward, so that the two sets of third gears 705 can mesh with the fourth gear 706 and rotate. In this way, the two sets of bidirectional screws 707 can rotate forward simultaneously. At this time, the bidirectional screws 707 will rotate with the moving block 709 through the threaded hole 710, thereby driving the two sets of moving plates 711 to rotate simultaneously. The servo motor 701 moves inward, causing the fixed clamping assembly 8 to clamp and fix the base. Then, the servo motor 701 can be turned off, and the grinding motor 5 can be started to drive the grinding disc 6 to rotate. Then, the electric push rod 3 is turned on to push the lifting plate 4 down, so that the grinding disc 6 can grind the surface of the base. After grinding, the electric push rod 3 can drive the lifting plate 4 to move upward. At this time, the reverse rotation function of the servo motor 701 can be turned on. Through gear meshing, the two sets of bidirectional screws 707 are driven to reverse simultaneously, which causes the two sets of moving plates 711 to drive the two sets of fixed clamping assemblies 8 to move to both sides, releasing the clamping of the base. This avoids the problem that the clamping force is easily reduced or unstable by the spring clamping method, thus affecting the grinding effect.

[0026] Example 2, as Figure 1 and Figure 4 As shown, a fixing clamping assembly 8 is provided on the inner side of the movable plate 711. The fixing clamping assembly 8 includes a slot 801, which is opened inside the movable plate 711. A plug block 803 is inserted into the slot 801. A clamping plate 802 is connected to one side of the plug block 803. A handle 804 is connected to the top of the movable plate 711. Two sets of magnetic plug rods 805 are connected to the bottom of the handle 804.

[0027] The overall effect of Embodiment 2 is that when processing plastic bases of different shapes, the handle 804 can be pulled upwards to allow the magnetic insertion rod 805 to be pulled out from the insertion block 803. Then, the clamping plate 802 can be pulled outwards to pull the insertion block 803 out from the slot 801 to complete the disassembly. When a new clamping plate 802 needs to be installed, the insertion block 803 of the new clamping plate 802 can be inserted into the slot 801, and the handle 804 can be pushed downwards to allow the magnetic insertion rod 805 to be inserted into the insertion block 803 and magnetically fixed with it. This allows for the replacement of clamping plates 802 of different shapes, improves the practicality of the device, and facilitates the clamping and fixing of bases of different shapes.

[0028] Working principle: When grinding the plastic base, the servo motor 701 can be turned on to drive the first gear 702 to rotate. This drives the two sets of bidirectional screws 707 to rotate simultaneously through gear meshing. As the bidirectional screws 707 rotate, they drive the two sets of fixing clamping components 8 to clamp and fix the plastic base. Then, the grinding motor 5 can be started to grind the base. This avoids the problem that spring clamping can easily cause a decrease or instability in clamping force, thus affecting the grinding effect. When grinding bases of different shapes, the magnetic insertion rod 805 can be pulled out and the clamping plate 802 of different shapes can be replaced, which improves the practicality of the device and makes it easy to clamp and fix bases of different shapes.

[0029] The above are merely preferred embodiments of this utility model and are not intended to limit the 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 this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
