Abstract
Description
Technical Field
[0001] This utility model relates to the field of bakelite product manufacturing technology, specifically a bakelite product manufacturing and polishing device. Background Technology
[0002] Bakelite products are made of phenolic plastics with wood flour as filler. In the plastics industry, they are also known as bakelite. They are made by pressing bakelite powder or bakelite powder. Phenolic resin is the key raw material for bakelite products. It has good heat resistance, insulation and mechanical strength.
[0003] In the production of bakelite products, sanding is a crucial process. If residual gas exists during the curing process of bakelite materials, it may form surface bubbles or tiny depressions. Sanding can smooth the surface and cover or eliminate these defects. Currently, bakelite products need to be clamped for fixation. Most existing fixing methods use clamps to clamp and fix the outer surface. Since the clamps occupy the outer area of the bakelite products during fixation, it is inconvenient to sand the ends. Therefore, a sanding device for bakelite product production is proposed. Utility Model Content

[0020] Compared with the prior art, this utility model provides a sanding device for the production of bakelite products, which has the following beneficial effects:
[0021] 1. This bakelite product manufacturing and polishing device uses a second motor to drive a worm gear and worm wheel transmission, which in turn drives the lead screw to rotate and move the moving block to the left. The eight support rods gradually become vertical and push the four positioning plates outward, thus fixing the inner circle of the hollow bakelite product. This structure can automatically adjust the position of the positioning plates according to the inner diameter of the product. The four positioning plates are evenly stressed, which can not only firmly clamp hollow bakelite products of different specifications, but also avoid deformation caused by uneven clamping force.

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.
[0029] Please see Figure 1-4 This utility model provides a new technical solution: a sanding device for the production of bakelite products, including a sanding table 1, on the upper surface of the sanding table 1, a belt sander 2 is fixedly installed;
[0030] The grinding table 1 is equipped with a grinding mechanism, which includes an electric guide rail 3, a moving plate 4, a hollow column 5, a first motor 6, a gear 7, a gear ring 8, a sliding groove 9, a second motor 10, a worm gear 11, a worm wheel 12, a lead screw 13, a moving block 14, a support rod 15, and a positioning plate 16.
[0031] Furthermore, the electric guide rail 3 is fixedly installed on the upper surface of the grinding table 1, and the movable plate 4 is slidably sleeved on the outer surface of the electric guide rail 3.
[0032] Furthermore, the first motor 6 is fixedly mounted on the right surface of the movable plate 4, and the gear 7 is fixedly sleeved on the outer surface of the output shaft of the first motor 6.
[0033] The gear ring 8 is meshed with the outer surface of the gear 7.
[0034] Furthermore, the hollow column 5 is fixedly sleeved on the inner surface of the toothed ring 8, and the hollow column 5 is rotatably connected to the right surface of the movable plate 4.
[0035] Four grooves 9 are formed on the right surface of the hollow column 5.
[0036] Furthermore, the second motor 10 is fixedly installed in the inner wall of the hollow column 5, and the worm gear 11 is fixedly installed at the output end of the second motor 10;
[0037] The worm gear 12 is meshed with the outer surface of the worm 11.
[0038] Furthermore, the lead screw 13 is fixedly sleeved on the inner surface of the worm gear 12, the left end of the lead screw 13 is rotatably connected to the inner surface of the hollow column 5, and the right end of the lead screw 13 extends through the right surface of the hollow column 5.
[0039] The movable block 14 is threaded onto the outer surface of the lead screw 13.
[0040] Furthermore, eight support rods 15 are rotatably connected to the outer surface of the movable block 14, and four positioning plates 16 are rotatably connected to the end of the eight support rods 15 away from the movable block 14.
[0041] When using this bakelite product production and polishing device, the hollow bakelite product is placed on the outer surface of the four positioning plates 16. The second motor 10 is then started, driving the worm gear 11 fixedly mounted at its output end to rotate. The worm gear 11 drives the worm wheel 12, which is meshed with the outer surface, to rotate. The worm wheel 12 drives the lead screw 13, which is fixedly sleeved on the inner surface, to rotate. At this time, the moving block 14, threaded on the outer surface of the lead screw 13, continuously moves to the left through the threads on the outer surface of the lead screw 13. The moving block 14 then drives the eight support rods 15, which are rotatably connected to the outer surface, to move to the left. As they move, the eight support rods 15 gradually become vertical, thus moving away from the center of the product. The positioning plate 16, which is rotatably connected to one end of the moving block 14, applies an outward pushing force. At this time, the positioning plate 16 internally supports and fixes the hollow bakelite product. Then, by starting the electric guide rail 3, the electric guide rail 3 drives the moving plate 4, which is slidably sleeved on the outer surface, to move to the right. The bakelite product fixed on the moving plate 4 is brought close to the belt sander for sanding. At this time, by starting the first motor 6, the first motor 6 drives the gear 7, which is fixedly sleeved on the outer surface of the output shaft, to rotate. The gear 7 drives the gear ring 8, which is meshed with the outer surface, to rotate. The gear ring 8 drives the hollow column 5, which is fixedly sleeved on the inner surface, to rotate. The hollow column 5 drives the fixed bakelite product to rotate for circumferential sanding.
[0042] This bakelite product manufacturing and polishing device uses a second motor 10 to drive a worm gear 11 and a worm wheel 12, which in turn rotates the lead screw 13, causing the moving block 14 to move to the left. This causes eight support rods 15 to gradually become vertical and push four positioning plates 16 outwards, thus fixing the inner diameter of the hollow bakelite product. This structure can automatically adjust the position of the positioning plates 16 according to the inner diameter of the product. The four positioning plates 16 are evenly stressed, which not only securely clamps hollow bakelite products of different specifications but also avoids deformation caused by uneven clamping force. It is suitable for high-precision positioning of workpieces with various inner diameters, facilitating subsequent polishing. Providing a stable foundation to ensure the workpiece does not wobble during sanding, this bakelite product manufacturing sanding device uses an electric guide rail 3 to drive a moving plate 4 to bring the workpiece close to the belt sander. At the same time, the first motor 6 drives the hollow column 5 to rotate through gears 7 and gear rings 8, causing the fixed bakelite product to rotate. The combined motion of linear movement and circumferential rotation, in conjunction with the belt sander, ensures that all areas of the workpiece's outer surface are evenly in contact with the sanding belt, avoiding sanding blind spots. Moreover, the rotation speed and movement speed are adjustable to adapt to different needs, ensuring sanding accuracy and consistency, and improving overall processing efficiency.
