Description
Technical Field
[0001] The utility model relates to the technical field of plastic welding and fixing, and particularly relates to a plastic welding and fixing device. Background Art
[0002] In the field of plastic processing, plastic welding is a common and important process. However, in the traditional plastic welding process, many problems are often faced. In the previous welding operations, due to the lack of an effective fixing device, the plastic parts are prone to position deviation during welding, which seriously affects the welding quality and precision, resulting in the welded products not meeting the requirements, increasing the rejection rate and production cost. The traditional fixing devices usually can only fix the fixed shape or surface. For some plastic parts with special-shaped structures, the existing fixing methods are often difficult to achieve comprehensive and stable clamping, making the welding process complex and difficult, and prone to the phenomenon of insecure welding. In addition, when welding plastic products with multiple welding surfaces, if the welding angle needs to be adjusted, it is usually necessary to repeatedly disassemble and reinstall the plastic parts, which is not only cumbersome to operate, time-consuming, but also increases the labor intensity and greatly affects the welding efficiency.

[0022] The outer wall of the top of the fixed ring 26 is fixedly connected to the inner wall of the top of the positioning block 21. The outer wall of the clamping guide rod 24 is slidably connected to the inner wall of the positioning block 21. The telescopic function of the hydraulic rod 23 enables the clamping guide rod 24 to slide along the inner walls of the positioning block 21 and the fixed ring 26.
[0023] A rotating rod 251 is rotatably connected to the inner wall of the positioning groove 211. A clamping jaw 25 is fixedly connected to the outer wall of the rotating rod 251. A pulley 252 is rotatably connected to the inner wall of the bottom of the clamping jaw 25. A threaded rod 253 is threadedly connected to the inner wall of the top of the clamping jaw 25. A rotating wheel 254 is fixedly connected to the outer wall of the threaded rod 253. A rotating ball 255 is fixedly connected to the outer wall of the threaded rod 253 on the side away from the rotating wheel 254. A clamping block 256 is slidably connected to the outer wall of the rotating ball 255. A rubber pad 257 is fixedly connected to the outer wall of the clamping block 256.
[0024] The clamping jaws 25 are annularly arrayed around the central point of the axis of the fixed ring 26, and the number is the same as that of the tension springs 27 and the positioning grooves 211. The outer wall of the pulley 252 is slidably connected to the outer wall of the clamping guide rod 24. By moving the clamping guide rod 24 up and down, the pulley 252 slides along the inclined surface of the outer wall of the clamping guide rod 24. Through the sliding of the inclined surface and the rotation of the rotating rod 251, the top of the clamping jaw 25 is tightened or opened. The outer wall of the clamping jaw 25 is fixedly connected to the outer wall of the tension spring 27 on the side away from the fixed ring 26. When the clamping guide rod 24 moves downward, it guides the clamping jaw 25 to contract inward.
[0025] The adjusting device 1 includes an adjusting block 11. A rotating rod 12 is rotatably connected to the inner wall of the adjusting block 11. A gear 13 is fixedly connected to the outer wall of the rotating rod 12. A rotating handle 14 is fixedly connected to the outer wall of the rotating rod 12 on the side away from the gear 13. A sliding groove 15 is formed in the inner wall of the adjusting block 11.
[0026] The outer wall of the adjusting gear disk 22 is slidably connected to the inner wall of the sliding groove 15. The outer wall of the positioning block 21 is slidably connected to the inner wall of the top of the adjusting block 11. The outer wall of the adjusting gear disk 22 is meshed with the outer wall of the gear 13. By rotating the gear 13, the adjusting gear disk 22 is driven to rotate, thereby driving the entire positioning device 2 to rotate.
[0027] Working principle: When welding plastic parts, place the plastic parts on the positioning device 2, start the hydraulic rod 23, and drive the clamping guide rod 24 fixedly connected to the top to move upward through the lifting of the hydraulic rod 23. During the upward movement of the clamping guide rod 24, the outer wall thereof is in sliding contact with the pulley 252 rotatably connected to the inner wall of the bottom of the clamping jaw 25, thereby pushing the clamping jaw 25 to rotate along the rotating rod 251 rotatably connected to the inner wall of the positioning groove 211, so that the clamping block 256 at the top clamps inward. At the same time, the clamping guide rod 24 slidably connected to the inner wall of the positioning block 21 approaches, and the plastic part is fixed around by the clamping block 256 to prevent position deviation during the welding process. At the same time, the clamping guide rod 24 moves upward to abut against the bottom of the plastic part to prevent the plastic part from moving downward during the welding process, resulting in an insecure welding surface. Similarly, when releasing the plastic part, the clamping guide rod 24 moves downward, and the tension spring 27 guides the clamping jaw 25 to contract inward downward through the fixed ring 26, so that the clamping jaw 25 on the upper part of the rotating rod 251 opens outward. The cooperation of the clamping block 256 and the clamping guide rod 24 fixes the plastic part. If a plastic part with a special-shaped structure is encountered, resulting in the clamping block 256 on one or both sides not contacting the plastic part, rotate the rotating wheel 254 to drive the threaded rod 253 to rotate. At the same time, the rotating ball 255 fixed to the outer wall of the threaded rod 253 moves the clamping block 256 toward the plastic part under the action of threaded connection until it fits the surface of the plastic part and fixes it. And through the spherical structure on the surface of the rotating ball 255, the clamping block 256 can be adjusted at a certain angle, so that the clamping block 256 fits more closely to the surface of the plastic part. At the same time, the rubber pad 257 on the outer wall of the clamping block 256 can increase the friction with the plastic part and prevent the clamping block 256 from directly contacting and damaging the surface of the plastic part.
[0028] When it is necessary to adjust the position and angle of the plastic part, rotate the turning handle 14 to drive the fixedly connected rotating rod 12 to rotate, and the gear 13 fixedly connected to the rotating rod 12 rotates accordingly. Since the outer wall of the adjusting tooth disc 22 of the positioning device 2 is meshed with the outer wall of the gear 13, and the outer wall of the adjusting tooth disc 22 is slidably connected to the inner wall of the sliding groove 15, and the outer wall of the positioning block 21 is slidably connected to the inner wall of the top of the adjusting block 11. When the gear 13 rotates, it will drive the adjusting tooth disc 22 to slide in the sliding groove 15, and then the whole positioning device 2 rotates in the adjusting device 1 to realize the adjustment of the position and angle of the plastic part. This setting can fully weld the periphery of the plastic part. As long as the rotating rod 12 is rotated, the angle can be adjusted, and there is no need to repeatedly disassemble and adjust the angle.
[0029] Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art and related fields based on the embodiments in the present utility model without creative efforts shall fall within the scope of protection of the present utility model. Structures, devices, and operation methods that are not specifically described and explained in the present utility model shall be implemented by conventional means in the art without special instructions and limitations.
