Description

Technical Field

[0001] This utility model relates to the field of clamping technology for processing plastic products, specifically a clamping device for processing plastic products. Background Technology

[0002] In the field of plastic product processing, clamping devices are key equipment to ensure processing accuracy and efficiency. However, many existing clamping devices have obvious limitations in design and function. On the one hand, some clamping devices have fixed structures, and the position and angle of their clamping arms cannot be flexibly adjusted according to plastic products of different shapes and sizes. This makes it difficult to achieve stable and accurate clamping when processing some irregularly shaped or special-specification plastic products, which can easily lead to displacement or deformation of the products during processing and affect product quality.

[0003] Existing clamping devices have low functional integration, often only possessing a single clamping function and lacking effective linkage and coordination with other processing steps. For example, when it is necessary to rotate plastic products for multi-faceted processing, such as removing burrs or surface polishing, existing devices only rotate the clamped plastic product through a rotating mechanism on one side in cooperation with the clamping structure, relying on the force on the plastic product itself to rotate it. This may cause damage to the plastic product. To address these issues, we propose a clamping device for processing plastic products. Utility Model Content

[0019] 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.

[0020] Example 1: Please refer to Figures 1-4 A clamping device for processing plastic products includes a worktable 1. The worktable 1 is placed in a suitable work area, and the device is placed stably by the support legs 2 at the bottom of the worktable 1. When clamping and processing plastic products, the servo motor 19 in the mounting groove on the right side of the top of the worktable 1 is started according to the length of the plastic product. The servo motor 19 drives the reciprocating screw 21 at the output end to rotate. Since the moving block 20 has a threaded hole that matches the reciprocating screw 21, and the top of the moving block 20 is fixedly connected to the bottom of the moving plate 16, the moving plate 16 moves along the slide rails 3 on both sides of the groove on the top of the worktable 1 under the guidance of the slide rails 3, thereby adjusting the distance between the moving plate 16 and the left fixed plate 4 to accommodate the placement of plastic products of different lengths.

[0021] The plastic product to be processed is placed between the two mounting seats 17. The handwheel 8 is turned, which drives the worm 9 to rotate. Since the worm 9 is located at the center of the three worm wheels 13 and meshes with the three worm wheels 13, the rotation of the worm 9 will drive the three worm wheels 13 to rotate. The worm wheels 13 are installed on the outer ring of the middle part of the rotating shaft 24. The rotation of the rotating shaft 24 causes the clamping arms 15, which are installed on both sides of the outer ring of the rotating shaft 24 and located between the worm wheels 13 and the support seat 23, to rotate around the rotating shaft 24. The multiple clamping arms 15 cooperate with each other to clamp the plastic product. The rubber protective pad 14 installed on the side of the clamping arm 15 away from the rotating shaft 24 can prevent the plastic product from being pinched.

[0022] When it is necessary to perform rotary processing on plastic products, the drive motor 7 on the mounting plate 6 on the top left of the workbench 1 is started. The first gear 5 at the output end of the drive motor 7 rotates. Since the rotating plate 11 is located on the outer ring of the fixed plate 4 and the moving plate 16, which are far apart from each other, a gear ring 10 is fixedly installed. The first gear 5 meshes with the gear ring 10 installed on the rotating plate 11 on the fixed plate 4, thereby driving the rotating plate 11 on the fixed plate 4 to rotate. At the same time, the rotating rod 12 at the output end of the drive motor 7 rotates. The right end of the rotating rod 12 is rotatably connected to the left side of the support plate 18 on the top right of the workbench 1. The rotating rod 12 passes through the lower through hole of the moving plate 16 and the hexagonal through hole in the center of the second gear 22. The rotation of the rotating rod 12 drives the second gear 22 to rotate. The second gear 22 meshes with the gear ring 10 installed on the rotating plate 11 on the moving plate 16, thereby driving the rotating plate 11 on the moving plate 16 to rotate. The synchronous rotation of the two rotating plates 11 enables the clamped plastic products to rotate, which facilitates multi-faceted processing and avoids damage to the plastic products.

[0023] Example 2: Please refer to Figures 1-4 In another application scenario, the device is first placed stably on the support leg 2. After the plastic product is placed, the worm gear 9 is driven to rotate by turning the handwheel 8. The worm gear 9 drives the worm wheel 13, the rotating shaft 24, and the clamping arm 15 to rotate, thereby clamping the plastic product. If a small-angle rotation adjustment of the plastic product is required during processing, the drive motor 7 can be started by the PLC controller, and the speed of the drive motor 7 can be adjusted to meet the required speed. At this time, the drive motor 7 drives the first gear 5 and the rotating rod 12 to rotate. The first gear 5 meshes with the gear ring 10 installed on the outer ring of the rotating plate 11 on the fixed plate 4. The rotating rod 12 drives the second gear 22 to mesh with the gear ring 10 installed on the outer ring of the rotating plate 11 on the moving plate 16, so that the two rotating plates 11 rotate slowly, thereby driving the plastic product to rotate at a small angle to meet the needs of fine processing.

[0024] Implementation effect: A groove is opened on the top right side of the workbench 1 and a moving block 20 is set there. The top of the moving block 20 is connected to the moving plate 16. The workbench 1 is equipped with slide rails 3 on both sides of the groove for the moving plate 16 to move. At the same time, a servo motor 19 is installed in the groove on the top right side of the workbench 1. The output end of the servo motor 19 is equipped with a reciprocating screw 21 that passes through the moving block 20. The moving block 20 is opened with a threaded hole that matches the reciprocating screw 21. The servo motor 19 drives the reciprocating screw 21 to rotate, which allows the moving block 20 to move the moving plate 16 along the slide rail 3. This allows for flexible adjustment of the distance between the moving plate 16 and the left fixed plate 4 to accommodate the placement and processing of plastic products of different lengths.

[0025] A mounting base 17 is installed at the center of the rotating plate 11. A worm gear 9 is rotatably connected to the center of the mounting base 17. The worm gear 9 meshes with a worm wheel 13 installed on the outer ring of the middle part of the rotating shaft 24. Clamping arms 15 are installed on both sides of the rotating shaft 24. A rubber protective pad 14 is provided on the side of the clamping arm 15 away from the rotating shaft 24. Rotating the handwheel 8 drives the worm gear 9 to rotate, which in turn drives the worm wheel 13, the rotating shaft 24 and the clamping arm 15, so as to achieve stable clamping of plastic products, and the protective pad 14 can prevent damage to the plastic products.

[0026] Two rotating plates 11 are fixedly mounted on the outer rings of the fixed plate 4 and the moving plate 16 on opposite sides. A first gear 5 is mounted on the output end of the drive motor 7 on the top left mounting plate 6 of the worktable 1. A second gear 22 is rotatably connected to the lower part of the right side wall of the moving plate 16. A rotating rod 12 passes through the hexagonal through hole in the center of the second gear 22 and its right end is rotatably connected to the left side of the support plate 18. The first gear 5 and the second gear 22 mesh with the two gear rings 10 respectively. Starting the drive motor 7 can drive the first gear 5 and the rotating rod 12 to rotate, thereby making the two rotating plates 11 rotate synchronously, realizing the rotation of the clamped plastic product, avoiding damage to the plastic product during rotation, and facilitating multi-faceted processing.
