Description

Technical Field

[0001] This invention relates to the field of arc welding machine technology, and specifically to a horizontal automatic circumferential arc welding machine for lamp processing. Background Technology

[0002] When manufacturing lighting fixtures, welding machines are often needed to strengthen the connections between certain structural components. Existing streetlights or large lights require a base for installation. These bases typically consist of a base body and a cylindrical component welded to it. Therefore, during manufacturing, the cylindrical component should ideally be centered within the base body. However, current welding machines often use fixing mechanisms to secure the base body, requiring manual positioning of the cylindrical component. This method is prone to misalignment when welding the cylindrical component if the welder is inexperienced.

[0003] Therefore, this invention proposes a horizontal automatic circumferential arc welding machine for lamp processing. Summary of the Invention

[0004] The purpose of this invention is to provide a horizontal automatic circumferential arc welding machine for lamp processing, in order to solve the problems mentioned above in the background art.

[0005] To achieve the above objectives, the present invention specifically adopts the following technical solution: A horizontal automatic circumferential arc welding machine for lamp processing, comprising: Mounting bracket, on which welding heads are mounted, and a drive motor is mounted on the mounting bracket; A fastener is installed on a mounting bracket. The fastener includes a receiving cavity and a fixing part. The receiving cavity is used to receive the base body, and the fixing part is used to restrict the movement of the base body within the receiving cavity. The fastener is connected to the output shaft of the drive motor. A clamping member is slidably mounted on a mounting bracket. The clamping member includes a clamping cavity and a clamping part. The clamping cavity is used to accommodate a cylindrical component, and the clamping part is used to restrict the sliding of the cylindrical component within the clamping cavity. The positioning structure includes a positioning plate mounted on a mounting bracket. The clamping part has a positioning hole. When the positioning plate is inserted into the positioning hole, the axes of the clamping cavity and the receiving cavity are on the same straight line.

[0006] Furthermore, the fixing part includes a fixing cylinder rotatably mounted on the mounting frame, a connecting cylinder slidably mounted on the fixing cylinder, a limiting hole provided on the mounting frame, and a clamping plate hinged to the connecting cylinder. There are multiple clamping plates, and a contact spring is installed between the clamping plates. The contact spring forces the free ends of the clamping plates to move away from each other. When the clamping plates abut against the inner wall of the limiting hole, the clamping plates move closer to each other and clamp the base body.

[0007] Furthermore, the clamping part includes a mounting plate slidably mounted on the mounting frame, a clamping cavity being formed on the mounting plate, a baffle plate slidably mounted on the mounting plate, a connecting spring being installed between the baffle plate and the mounting plate, a limiting plate being rotatably mounted on the baffle plate, an elastic plate being mounted on the limiting plate, the elastic plate being obliquely mounted on the limiting plate with the end of the elastic plate having a larger distance between it facing the fixed cylinder, and the elastic plate being used to abut against the cylindrical component.

[0008] Furthermore, an extension plate is installed on the free end of the elastic plate, and a rubber plate is installed on the extension plate. The extension plate contacts the cylindrical component through the rubber plate.

[0009] Furthermore, the positioning structure also includes a rotating rod rotatably mounted on a limiting plate, an extension sleeve mounted on the limiting plate, and a driving sleeve slidably mounted on the extension sleeve. There are two driving sleeves. The free end of the rotating rod is provided with a bidirectional thread. The driving sleeve is threadedly connected to the rotating rod. An abutment rod is hinged on the driving sleeve. The free ends of the abutment rods located on the two driving sleeves are hinged to each other.

[0010] Furthermore, the positioning plate is arc-shaped and located on the side of the limiting hole away from the welding head, and the projection of the positioning plate on the welding head covers the welding head.

[0011] Furthermore, an insertion plate is mounted on the mounting plate, and a slot for accommodating the insertion plate is provided on the mounting bracket. A retraction spring is installed in the slot, and a pressure plate for abutting against the insertion plate is installed at the free end of the retraction spring. A push spring is installed in the slot, and an abutting block for abutting against the pressure plate is installed at the free end of the push spring. A channel groove communicating with the slot is provided on the positioning plate, and a pressing rod for abutting against the abutting block is slidably installed in the channel groove. A blocking block is also slidably installed in the channel groove. When the pressing rod abuts against the blocking block, the cross-sectional area of ​​the positioning plate is larger than the cross-sectional area of ​​the positioning hole.

[0012] Furthermore, an extension column is installed on the connecting cylinder, and a suction cup is installed at the free end of the extension column. The suction cup is used to generate an attractive force on the base body.

[0013] Furthermore, an expansion panel is installed at the free end of the clamping plate. When the base body is clamped by the clamping plate, the projection of the expansion panel along the axial direction of the receiving cavity is located on the base body.

[0014] Furthermore, a guide groove is provided inside the fixed cylinder, and a guide block that is slidably inserted into the guide groove is installed on the connecting cylinder.

[0015] The beneficial effects of this invention are as follows: 1. When welding, the base body is first fixedly installed in the receiving cavity by the fixing part, the cylindrical part is clamped and fixed by the clamping part, and then the clamping part is slid to bring the cylindrical part closer to and contact the base body. Physical locking is achieved by the insertion and cooperation of the positioning plate and the positioning hole. The multi-dimensional adaptive clamping and fixing receiving cavity is constructed by using rigid and flexible structure settings, which makes it easier for the device to clamp the cylindrical part and the base body more stably.

[0016] 2. Furthermore, because the mounting plate is installed at an angle, when the cylindrical component is connected to the base body, the weight of the cylindrical component itself can play a role in stabilization through sliding. When the cylindrical component contacts the base body, the axis of the cylindrical component is collinear with the axis of the base body, thus positioning the two. The welding accuracy is improved through multi-axis collinearity and multi-station linkage control, the operation process is simplified, and the practicality of the device is enhanced.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0020] like Figure 1 - Figure 12 As shown, an embodiment of the present invention provides a horizontal automatic circumferential arc welding machine for lamp processing, comprising: Mounting frame 1, on which welding head 101 is mounted, and drive motor 102 is mounted on mounting frame 1. Welding head 101 is a welding gun in the prior art, including conductive nozzle, gas nozzle and cooling channel, used to conduct current, guide welding wire and spray protective gas. When welding wire is required, the device can use a robot to hold welding wire for welding. In use, welding head 101 is used to weld between base body and cylindrical component. The fixing component 2 is installed on the mounting frame 1. The fixing component 2 includes a receiving cavity 201 and a fixing part. The receiving cavity 201 is used to receive the base body, and the fixing part is used to restrict the movement of the base body in the receiving cavity 201. The fixing component 2 is connected to the output shaft of the drive motor 102. When the device is in use, the base body is fixedly installed in the receiving cavity 201 through the cooperation of the fixing part, and the position of the base body on the mounting frame 1 is fixed, which reduces the possibility of the base body shifting during welding and increases the stability of the base body when the device is in use. The base body is rotated by starting the drive motor 102 through the fixing component 2. The clamping member 3 is slidably mounted on the mounting frame 1. The clamping member 3 includes a clamping cavity 301 and a clamping part. The clamping cavity 301 is used to accommodate the cylindrical component, and the clamping part is used to restrict the sliding of the cylindrical component in the clamping cavity 301. In use, the clamping part clamps the cylindrical component by clamping, and the clamping direction is along the axial direction of the cylindrical component. It can clamp the cylindrical component without affecting the rotation of the cylindrical component as the base body rotates, which increases the feasibility of the device. The positioning structure 4 includes a positioning plate 401 mounted on the mounting bracket 1. A positioning hole 402 is provided on the clamping part. When the positioning plate 401 is inserted into the positioning hole 402, the axes of the clamping cavity 301 and the receiving cavity 201 are on the same straight line. When the device is in use, the base body is installed in the receiving cavity 201, the cylindrical component is fixed in the clamping cavity 301, and then the clamping component 3 is slid. During this process, the positioning hole 402 and the positioning plate 401 are gradually inserted and connected. The inner wall of the positioning hole 402 is blocked and restricted by the side wall of the positioning plate 401, thereby restricting the sliding direction of the clamping component 3. This forces the relative position of the base body and the cylindrical component to remain fixed, so that the cylindrical component can be located at the center of the base body during welding, which increases the accuracy of the device in welding. Compared with existing technologies, during welding, the base body is first fixedly installed in the receiving cavity 201 by the fixing part, and the cylindrical part is clamped and fixed by the clamping part. Then, the clamping member 3 is slid to bring the cylindrical part closer to and into contact with the base body. During the sliding of the clamping member 3, the positioning plate 401 is inserted into the positioning hole 402. The positioning plate 401 blocks and restricts the inner wall of the positioning hole 402, so that when the cylindrical part contacts the base body, the axis of the cylindrical part is collinear with the axis of the base body, thus positioning the two, increasing the welding accuracy and the practicality of the device.

[0021] like Figure 4 , Figure 5 and Figure 7 As shown, a portion of the structure of the fixing part is disclosed. In some embodiments, the fixing part includes a fixing cylinder 202 rotatably mounted on the mounting bracket 1. The fixing cylinder 202 is connected to the output shaft of the drive motor 102. When the drive motor 102 is started, it can drive the fixing cylinder 202 to rotate. A connecting cylinder 203 is slidably mounted on the fixed cylinder 202. The sliding direction of the connecting cylinder 203 is along the axis of the fixed cylinder 202. When the fixed cylinder 202 rotates, it can drive the connecting cylinder 203 to rotate with it. A limiting hole 206 is provided on the mounting frame 1. A plate is mounted on the mounting frame 1, and the limiting hole 206 is installed on the plate. A clamping plate 204 is hinged to the connecting cylinder 203. There are multiple clamping plates 204. The receiving cavity 201 is for when the clamping plates 204 are close to each other. A cavity is formed between the clamping plates 204, and an abutment spring 205 is installed between the clamping plates 204. The abutment spring 205 forces the free ends of the clamping plates 204 away from each other. When the clamping plates 204 abut against the inner wall of the limiting hole 206, the clamping plates 204 move closer together and clamp the base body. A plate is hinged to the clamping plates 204, and the end of the abutment spring 205 is connected to the plate. So when the clamping plates 204 are pushed away from each other by the abutment spring 205, the position where the plate is installed is set as A. For example, when the clamping plate 204 rotates away from the axis of the connecting cylinder 203, the position between the two points A will also change, causing the positions of the two ends of the abutment spring 205 to change as well. Therefore, a plate is hinged at point A. At this time, when the clamping plates 204 move away from each other, with the end face of the connecting cylinder 203 where the clamping plates 204 are installed as the horizontal plane, if one of the clamping plates 204 rotates clockwise, the plate on it will be pulled by the abutment spring 205 and rotate counterclockwise relative to the clamping plate 204. When the clamping plate 204 rotates counterclockwise, the plate on it will rotate clockwise relative to the clamping plate 204, reducing the deformation of the abutment spring 205 in the non-axial direction, thereby reducing the possibility of the abutment spring 205 fatigued too quickly and increasing the service life of the device. For ease of description later, the side of the limiting hole 206 facing the fixed cylinder 202 is designated as the near side, and the side away from the fixed cylinder 202 is designated as the open side. When the device is not installed with the base body, the hinge point between the clamping plate 204 and the connecting cylinder 203 is located on the open side. At this time, the free ends of the clamping plates 204 are far apart from each other. At this time, the opening diameter between the clamping plates 204 is larger than the diameter of the base body, which makes it easier to place the base body between the clamping plates 204. After the base body is placed between the clamping plates 204, the connecting cylinder 203 is slid. When the hinge point between the clamping plate 204 and the connecting cylinder 203 moves through the limiting hole 206 and moves to the near side, the inner wall of the limiting hole 206 gradually abuts against the clamping plate 204 and forces the clamping plate 204 to rotate and move closer to each other, forming a receiving cavity 201 to abut and clamp the base body. After the device clamps and fixes the base body, the sliding clamp 3 forces the base body into contact with the cylindrical component. The welding head 101 is used to weld the two components on the side closest to the welding head 101. During the process, the drive motor 102 drives the fixed cylinder 202 to rotate slowly, causing the base body to rotate. The clamp 3 clamps the cylindrical component, and the cylindrical component comes into contact with the base body, increasing the friction between them. This friction causes the drive motor 102 to rotate the base body while also moving the cylindrical component, causing the unwelded parts to gradually rotate and approach the welding head 101, thus completing the annular welding.

[0022] like Figure 3 , Figure 8 and Figure 10 As shown, a portion of the structure of the clamping part is disclosed. In some embodiments, the clamping part includes a mounting plate 302 that is slidably mounted on the mounting frame 1. The mounting frame 1 has a sliding groove, and a block that is slidably inserted into the sliding groove is mounted on the mounting plate 302. The side wall of the block is blocked by the inner wall of the sliding groove, which causes the mounting plate 302 to only move closer to or further away from the connecting cylinder 203 in a straight line. The clamping cavity 301 is formed on the mounting plate 302. A baffle plate 303 is slidably mounted on the mounting plate 302. A connecting spring 304 is installed between the baffle plate 303 and the mounting plate 302. A rod is mounted on the baffle plate 303. A channel is formed on the mounting plate 302 that is slidably connected to the rod. The connecting spring 304 is sleeved on the outside of the rod. By restricting the side wall of the rod through the inner wall of the channel, the baffle plate 303 is forced to move closer to or away from the mounting plate 302 along the axis of the clamping cavity 301. During the process, the connecting spring 304 is also forced to undergo elastic deformation along the axis of the rod by the baffle of the inner wall of the rod, which increases the stability of the connecting spring 304 during deformation. A limiting plate 305 is rotatably mounted on the baffle plate 303, and an elastic plate 306 is mounted on the limiting plate 305. The elastic plate 306 is obliquely mounted on the limiting plate 305, with the end of the elastic plate 306 with a larger distance between them facing the fixed cylinder 202. The elastic plate 306 is used to abut against the cylindrical component. When the cylindrical component is inserted into the clamping cavity 301, one end of it abuts against the elastic plate 306. Since the cylindrical component is inserted from the point of maximum distance to the point of minimum distance of the elastic plate 306, when it is inserted to abut against the elastic plate 306, the elastic deformation between the elastic plates 306 also generates a reverse abutting force on the cylindrical component, thereby clamping and fixing the cylindrical component. When the cylindrical component needs to be installed, it is inserted into the clamping cavity 301 from the side near the connecting cylinder 203. During this process, the cylindrical component abuts against the elastic plate 306, causing the elastic plate 306 to clamp the cylindrical component. During this abutment, the baffle plate 303 is pushed away from the mounting plate 302, stretching the connecting spring 304. At this point, after the sliding mounting plate 302 brings the cylindrical component into contact with the base body, the connected spring 304, being in a stretched state, exerts a force on the baffle plate 303 towards the connecting cylinder 203, causing the cylindrical component to abut against the base body. Meanwhile, the connecting cylinder 203 remains stationary. The sliding within the fixed cylinder 202 reaches its maximum value. Therefore, the contact of the cylindrical component can restrict the sliding of the connecting cylinder 203 within the fixed cylinder 202. During the process, the sliding of the mounting plate 302 can be restricted by the pin or other components. With the above settings, while the clamping member 3 can clamp the cylindrical component, it can also restrict the sliding of the connecting cylinder 203 during welding, which increases the practicality of the device. Furthermore, by pulling the connecting spring 304, the cylindrical component can be forced to be in a contacting state with the base body. Compared with a mere contact state, the contact between the two is tighter, which facilitates the strength and stability of the two after welding and increases the welding effect of the device. Compared to the method where a cylindrical component rotates between elastic plates 306 by overcoming friction, when the drive motor 102 drives the fixed cylinder 202 to rotate, since the limiting plate 305 is rotatably connected to the shielding plate 303 and the elastic plate 306 is mounted on the limiting plate 305, the limiting plate 305 also rotates on the shielding plate 303 while the cylindrical component rotates. Therefore, the cylindrical component can rotate more smoothly with the base body, making it easier to rotate, increasing the feasibility of the device, and causing less damage to the cylindrical component during rotation, thus increasing the practicality of the device.

[0023] like Figure 8 As shown, the specific structure of the elastic plate 306 is disclosed. In some embodiments, an extension plate 19 is installed on the free end of the elastic plate 306, and a rubber plate 5 is installed on the extension plate 19. The extension plate 19 contacts the cylindrical component through the rubber plate 5. The extension plate 19 is installed at the free end of the elastic plate 306 along the axial direction of the clamping cavity 301, which increases the contact area between the elastic plate 306 and the cylindrical component, thereby increasing the fixing strength of the elastic plate 306 on the cylindrical component. When the extension plate 19 clamps the cylindrical component, the extension plate 19 contacts the cylindrical component through the rubber plate 5. Firstly, the rubber plate 5 increases the friction between the two, further increasing the fixing strength of the device on the cylindrical component. Secondly, the flexible contact between the rubber plate 5 and the cylindrical component reduces the possibility of damage to the cylindrical component when the device fixes it, increasing the practicality of the device.

[0024] like Figure 8 and Figure 9 As shown, a portion of the structure of the positioning structure 4 is disclosed. In some embodiments, the positioning structure 4 further includes a rotating rod 403 rotatably mounted on a limiting plate 305. An extension sleeve 404 is mounted on the limiting plate 305. A driving sleeve 405 is slidably mounted on the extension sleeve 404. A rod is mounted on the extension sleeve 404. A channel is provided on the driving sleeve 405 to slide and engage with the rod, so that the driving sleeve 405 and the extension sleeve 404 are slidably connected. There are two drive sleeves 405. The free end of the rotating rod 403 is provided with a bidirectional thread. The drive sleeve 405 is threadedly connected to the rotating rod 403. The drive sleeve 405 is hinged with a contact rod 406. The free ends of the contact rods 406 on the two drive sleeves 405 are hinged to each other. The drive sleeves 405 are designated as sleeve one and sleeve two. The bidirectional thread is designated as thread one and thread two. Sleeve one is threadedly connected to thread one, and sleeve two is threadedly connected to thread two. When the rotating rod 403 rotates, the rod body on the extension sleeve 404 blocks the inner wall of the channel on the drive sleeve 405, so the drive sleeve 405 will not rotate with the rotating rod 403. This forces the drive sleeves 405 to only move closer or further apart from each other at the threaded part of the rotating rod 403. When the device is in use, the operator manually or with the help of a robotic arm presses down on the limiting plate 305 and rotates it to restrict movement. Then, the rotating rod 403 is rotated to bring the driving sleeves 405 closer together. When the driving sleeves 405 move closer together, the free end of the abutting rod 406 moves away from the driving sleeves 405. During use, the abutting rod 406 is located inside the cylindrical component. When the abutting rods 406 move away from each other, they will abut against the inner wall of the cylindrical component. Because the elastic plate 306 or other elastic elements clamp and abut against the cylindrical component through elastic deformation, the clamping and abutting action is affected by the elastic elements themselves. If used for a long time, the deformation degree of each elastic element will be different. Therefore, when clamping the cylindrical component, it is easy to cause unevenness. This causes the axis of the cylindrical component to be non-collinear with the axis of the clamping cavity 301. However, in this invention, when the abutment rod 406 is away from the drive sleeve 405, the movement distance of each abutment rod 406 on the drive sleeve 405 is consistent, and the axis of the rotating rod 403 is collinear with the axis of the clamping cavity 301. Therefore, when the abutment rod 406 abuts against the inner wall of the cylindrical component, it will force the part of the cylindrical component that has shifted to move by means of abutment, so that its axis is collinear with the axis of the clamping cavity 301. The cylindrical component is corrected by the abutment of the abutment rod 406, which increases the welding accuracy of the device and also increases the fixing strength of the device to the cylindrical component by the abutment of the abutment rod 406, thus increasing the practicality of the device.

[0025] like Figure 7As shown, a portion of the structure of the positioning plate 401 is disclosed. In some embodiments, the positioning plate 401 is arc-shaped and located on the side of the limiting hole 206 away from the welding head 101. The projection of the positioning plate 401 on the welding head 101 covers the welding head 101. In use, the positioning plate 401 blocks the side of the limiting hole 206 away from the welding head 101, allowing the operator to observe or avoid the welding process from the positioning plate 401, reducing the possibility of welding slag splashing onto the operator and increasing the safety of the device.

[0026] like Figure 3 , Figure 7 , Figure 11 and Figure 12 As shown, a portion of the structure on the mounting bracket 1 is disclosed. In some embodiments, an insertion plate 6 is mounted on the mounting plate 302, and a slot 7 for accommodating the insertion plate 6 is provided on the mounting bracket 1. A compression spring 8 is installed in the slot 7, and a pressure plate 9 for abutting against the insertion plate 6 is installed at the free end of the compression spring 8. The compression spring 8 forces the pressure plate 9 to move closer to the slot opening of the slot 7. When the mounting plate 302 approaches the connecting cylinder 203, the insertion plate 6 is gradually inserted into the slot 7. When the cylindrical component abuts against the base body, the insertion plate 6 is fully inserted into the slot 7 and abuts against the pressure plate 9. At this time, the compression spring 8 is compressed. A push spring 10 is installed in the slot 7. A contact block 11 for abutting against the pressure plate 9 is installed at the free end of the push spring 10. The axis of the push spring 10 is perpendicular to the axis of the retraction spring 8. When the insertion plate 6 abuts against the pressure plate 9, the pressure plate 9 moves into the slot 7. At this time, the pressure plate 9 also abuts against the contact block 11. At this time, the push spring 10 is compressed. The positioning plate 401 has a channel groove 12 that communicates with the slot 7. A pressing rod 20 for contacting the contact block 11 is slidably installed in the channel groove 12. A blocking block 13 is also slidably installed in the channel groove 12. The channel groove 12 has an opening that communicates with the outside. The blocking block 13 is installed at the opening. When the cylindrical component contacts the base body, the free end of the positioning plate 401 passes through the positioning hole 402. The opening is located at one end of the positioning plate 401 that passes through the positioning hole 402. When the pressing rod 20 contacts the blocking block 13, the cross-sectional area of ​​the positioning plate 401 is larger than the cross-sectional area of ​​the positioning hole 402. The contact block 11 has a slope on the side facing the pressure plate 9. The pressing rod 20 has a slope on the side facing the contact block 11. The blocking block 13 has a slope on the side facing the pressing rod 20. When the contact block 11 is pushed, it abuts against the extrusion rod 20. The extrusion rod 20 is forced to approach the blocking block 13 by the guide of the upper inclined surface and abuts against the blocking block 13. During the abutment process, the blocking block 13 is forced to move from the opening of the channel groove 12 to the outside of the channel groove 12 by the guide of the upper inclined surface. At this time, the blocking block 13 protrudes outside the positioning hole 402. The blocking block 13 blocks part of the mounting plate 302 around the positioning hole 402, limiting the sliding of the mounting plate 302 on the mounting bracket 1. This increases the stability of the mounting plate 302 during welding, reduces the possibility of displacement of the cylindrical parts during welding, and increases the feasibility of the device. The fixed cylinder 202, positioning plate 401, and mounting plate 302 are all installed at an angle on the mounting bracket 1. The height of the fixed cylinder 202 is lower than the height of the mounting plate 302. The insertion plate 6 is rotatably installed on the mounting plate 302. The opening of the slot 7 is greater than or equal to the length of the insertion plate 6. When the device is welded and needs to be unloaded, the insertion plate 6 is rotated to release it from contact with the pressure plate 9. The compression spring 8 is used to reset and pull the pressure plate 9 to release it from contact with the contact block 11. The push spring 10 is used to reset and pull the contact block 11. Block 11 is reset. Since the positioning plate 401 is installed at an angle, the inner wall of the channel groove 12 also has an inclined surface. The pressing rod 20 can slide and reset under the influence of gravity. Then, the blocking block 13 is pushed back into the channel groove 12 by manual or robotic arm cooperation. The blocking block 13 releases the blocking of the positioning hole 402, and the sliding of the mounting plate 302 is restored. The rotating rod 403 is reversed to release the contact between the abutting rod 406 and the inner wall of the cylindrical component. Then, the cylindrical component is removed from between the elastic plates 306 to complete the unloading. The mounting plate 302 has a platform. When the insertion plate 6 is rotated to the state where it can be inserted into the slot 7, its plate body is supported on the surface of the platform. The rotation of the insertion plate 6 during use is restricted by the support of the platform and the influence of the weight of the insertion plate 6 itself, so that it can be kept in the position of contacting the pressure plate 9. An electric push rod can be set under the platform to push the insertion plate 6, so as to rotate it and release its contact with the pressure plate 9, which increases the feasibility of the device. With the above settings, the positioning plate 401 can be positioned while the sliding of the mounting plate 302 is restricted, thus increasing the applicability of the device.

[0027] like Figure 5As shown, a portion of the structure on the connecting cylinder 203 is disclosed. In some embodiments, an extension column 14 is installed on the connecting cylinder 203, and a suction cup 15 is installed at the free end of the extension column 14. The suction cup 15 is used to generate an attractive force on the base body. When the base body is installed, since the clamping plate 204 is initially in an open state, it cannot effectively fix the base body. The operator needs to hold the base body between the clamping plates 204 by hand or with the help of a robot. However, by pressing the base body onto the suction cup 15, the base body is initially fixed. The operator does not need to hold the base body until the clamping plate 204 is closed. Moreover, since the suction cup 15 is made of rubber, it can deform. When the clamping plate 204 clamps the base body, it can correct the position of the base body by abutting, so that its axis is collinear with the axis of the receiving cavity 201, which increases the practicality of the device.

[0028] like Figure 5 As shown, a portion of the structure on the clamping plate 204 is disclosed. In some embodiments, an expansion panel 16 is mounted on the free end of the clamping plate 204. When the base body is clamped by the clamping plate 204, the projection of the expansion panel 16 along the axial direction of the receiving cavity 201 is located on the base body. When the clamping plate 204 has finished clamping the base body, the expansion panel 16 is located on the open side. When fixing the base body, the suction cup 15 is located on the proximal side and contacts the base body, limiting the displacement of the base body in that direction. The expansion panel 16 is located on the open side and contacts the base body. The diameter of the base body is larger than the diameter of the cylindrical component. When the two are in pre-contact, they will form an inverted T shape. The welding head 101 only needs to extend to the gap at the connection between the two. The sum of the diameters of the expansion panel 16 and the cylindrical component is smaller than the diameter of the base body. Therefore, the part of the expansion panel 16 that contacts the base body will not extend to the connection between the cylindrical component and the base body, so it will not affect the welding. The displacement of the base body in this direction is restricted, and the movement of the base body is further restricted, which increases the stability of the base body when it is being welded.

[0029] like Figure 6 As shown, in some embodiments, a guide groove 17 is provided inside the fixed cylinder 202, and a guide block 18 is slidably inserted into the guide groove 17 on the connecting cylinder 203. When the connecting cylinder 203 slides, the guide block 18 slides in the guide groove 17. The inner wall of the guide groove 17 blocks and restricts the side wall of the guide block 18, so that the connecting cylinder 203 can only slide along the axial direction of the fixed cylinder 202 and will not rotate inside the fixed cylinder 202. This increases the stability of the connecting cylinder 203 when sliding, and also ensures that the fixed cylinder 202 can smoothly drive the connecting cylinder 203 to rotate together without slipping, thus increasing the practicality of the device.

[0030] The components in this invention can not only be fully automated with the help of a robotic arm, but also be manually operated to complete welding or stop damage in a timely manner when the robotic arm's program or sensor malfunctions, thus increasing the practicality of the device.

[0031] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
