However, since the corrugated pipe is relatively soft as a whole and is prone to deformation, when the corrugated pipe is placed horizontally, the connection of the corrugated pipe is prone to bending and deformation. This will cause the welding head to be unable to align with the welding position, affecting the welding accuracy of the corrugated pipe. Utility Model Content

[0011] Compared with the prior art, the advantages and positive effects of the utility model are:

[0012] 1. In the utility model, when welding the connection position of the corrugated tube wave plate, the corrugated tube is sleeved on the outer side of the sleeve rod.

[0019] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0020] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0021] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides a high-precision vacuum bellows wave plate welding device, including: a base frame 1, a processing table 2 is fixedly connected to the top of the base frame 1, a motor 3 is fixedly connected to the bottom of the processing table 2, the output end of the motor 3 slides through the processing table 2 and extends to the upper side, a welding frame 5 is fixedly connected to the top of the processing table 2, and a laser welding head 6 is fixedly connected to the outer surface of the welding frame 5; a positioning component 4, the positioning component 4 is fixedly connected to the output end of the motor 3, the positioning component 4 includes a rotating shaft 401, a rotating disk 402 is fixedly connected to the upper end surface of the rotating shaft 401, a sleeve rod 403 is fixedly connected to the top center of the rotating disk 402, a plurality of first springs 405 are fixedly connected to the outer surfaces of both sides of the sleeve rod 403 at equal distances, and the end surfaces of the two groups of first springs 405 are fixedly connected There is a support plate 406, a socket 407 is provided on the top of the support plate 406, a fixing plate 408 is symmetrically fixedly connected to the outer surface of the sleeve rod 403, a second spring 409 is fixedly connected to the bottom of the fixing plate 408, a connecting plate 410 is fixedly connected between the lower end surfaces of the two second springs 409, an insertion rod 411 is symmetrically fixedly connected to the bottom of the connecting plate 410, the outer surface of the insertion rod 411 is plugged into the inner surface of the socket 407, the first spring 405 is in a compressed state, a fixing sleeve 412 is fixedly connected to the outer surface of the sleeve rod 403, a side frame 413 is symmetrically fixedly connected to the outer surface of the fixing sleeve 412, and the side frame 413 is fixedly connected to the top of the connecting plate 410, the motor 3 is electrically connected to the laser welding head 6, and the laser welding head 6 is located outside the turntable 402.

[0022] The effect achieved by the entire embodiment 1 is that when welding is performed on the connection position of the bellows wave plate, the support plates 406 on both sides are in a docking state, the first spring 405 is in a compressed state, the bellows is sleeved on the outer side of the sleeve rod 403, and then the fixing sleeve 412 is pulled upward. The fixing sleeve 412 can drive the connecting plate 410 to move upward through the connection with the side frame 413, and the connecting plate 410 can drive the insertion rod 411 to move upward and be pulled out from the insertion hole 407. After the insertion rod 411 is pulled out, the rebound force of the first spring 405 can be used to make the support plates 406 on both sides expand outward synchronously. After the support plates 406 expand outward, the bellows can be supported from the inner side of the bellows. At this time, The inner wall of the bellows is supported and fixed, and the motor 3 and the laser welding head 6 are started synchronously to weld the bellows. The laser welding head 6 welds the connection position of the bellows from the outer side of the bellows. At the same time, the operation of the motor 3 drives the rotating shaft 401 to rotate, and the rotating shaft 401 drives the turntable 402 to rotate. The rotation of the turntable 402 can make the bellows rotate, completing the welding and fixing of the connection position of the bellows. While the bellows is being rotated and welded, the inner wall of the bellows is supported by the support plate 406, so that the outer wall of the bellows is in a relatively full state, thereby avoiding bending deformation of the bellows during welding, which affects the accuracy of the welding position and improves the welding process quality.

[0023] Embodiment 2, as Figure 1-Figure 4 As shown, a bracket 7 is fixedly connected to the top of the processing table 2, an electric telescopic rod 8 is fixedly connected to the outer surface of the bracket 7, a pressing ring 9 is fixedly connected to the upper end surface of the electric telescopic rod 8, and the pressing ring 9 is located outside the sleeve rod 403.

[0024] The effect achieved by the entire embodiment 2 is that when the bellows is sleeved on the outside of the sleeve rod 403 for clamping and positioning, the electric telescopic rod 8 is started to contract to drive the pressure ring 9 to move downward. After the pressure ring 9 moves downward, the bellows can be pressed and fixed, so that when the support plate 406 expands and clamps the bellows, the bellows is in a relatively stable state, thereby improving the stability of the fixed position of the bellows. After the fixation is completed, the electric telescopic rod 8 is started to extend to drive the pressure ring 9 to move upward and reset, and the bellows can be welded.

[0025] Working principle: when welding the connection position of the bellows wave plate, the support plates 406 on both sides are in a docking state, and the first spring 405 is in a compressed state. The bellows is sleeved on the outer side of the sleeve rod 403, and then the fixed sleeve 412 is pulled upward. The fixed sleeve 412 can drive the connecting plate 410 to move upward through the connection of the side frame 413, and the connecting plate 410 can drive the insertion rod 411 to move up and be pulled out from the insertion hole 407. After the insertion rod 411 is pulled out, the rebound force of the first spring 405 can be used to make the support plates 406 on both sides expand outward synchronously. After the support plates 406 expand outward, the bellows can be supported from the inner side of the bellows. At this time, the inner wall of the bellows is supported and fixed. At this time, the motor 3 and the laser welding head 6 are started synchronously to weld the bellows. The laser welding head 6 is started from the outer side of the bellows. The bellows connection position is welded, and at the same time, the motor 3 runs to drive the rotating shaft 401 to rotate, and the rotating shaft 401 drives the turntable 402 to rotate accordingly. Through the rotation of the turntable 402, the bellows can be rotated accordingly, completing the welding and fixation of the bellows connection position. While the bellows is rotating and welding, since the inner wall of the bellows is supported by the outward expansion of the support plate 406, the outer wall of the bellows is in a relatively full state, thereby avoiding bending deformation of the bellows during welding that affects the accuracy of the welding position, thereby improving the welding processing quality. When the bellows is sleeved on the outside of the sleeve rod 403 for clamping and positioning, the electric telescopic rod 8 is started to contract and drive the pressure ring 9 to move downward. After the pressure ring 9 moves downward, the bellows can be pressed and fixed, so that when the support plate 406 expands and clamps the bellows, the bellows is in a relatively stable state, thereby improving the stability of the fixed position of the bellows.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields.
