[0041] The clamping part 3 is slidably installed on the mounting frame 1, the clamping part 3 includes a clamping cavity 301 for containing the cylindrical part and a clamping part for limiting the sliding of the cylindrical part in the clamping cavity 301, in use, the clamping part clamps the cylindrical part in the direction along the axis of the cylindrical part, which can clamp the cylindrical part without affecting the rotation of the base body, thereby increasing the feasibility of the device.

[0042] The positioning structure 4 includes a positioning plate 401 installed on the mounting frame 1, and a positioning hole 402 is formed in the clamping part, when the positioning plate 401 is inserted into the positioning hole 402, the axes of the clamping cavity 301 and the containing cavity 201 are in the same straight line, when the device is in use, the base body is installed in the containing cavity 201, the cylindrical part is fixed in the clamping cavity 301, and then the clamping part 3 is slid, in this process, the positioning hole 402 and the positioning plate 401 are gradually connected by insertion, the sliding direction of the clamping part 3 is limited by the side wall of the positioning plate 401 shielding the inner wall of the positioning hole 402, thereby forcing the relative position of the base body and the cylindrical part to remain fixed, so that the cylindrical part can be located at the center of the base body during welding, thereby increasing the accuracy of the device during welding.

[0043] Compared with the prior art, during welding, the base body is first fixedly installed in the containing cavity 201 by the fixing part, the cylindrical part is clamped and fixed by the clamping part, and then the clamping part 3 is slid to approach and contact the base body, in the process of sliding the clamping part 3, the positioning plate 401 is inserted into the positioning hole 402, the inner wall of the positioning hole 402 is shielded and limited by the positioning plate 401, so that when the cylindrical part contacts the base body, the axis of the cylindrical part and the axis of the base body are collinear, the two are positioned, the accuracy of welding is increased, and the practicality of the device is increased.

[0044] As Figure 4 , Figure 5 and Figure 7As 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.

[0045] 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.

[0046] When the device is not installed in the base body, the clamping plate 204 and the connecting cylinder 203 hinge point is located on the side of the open, at this time, the free end of the clamping plate 204 away from each other, at this time, the opening between the clamping plate 204 is greater than the diameter of the base body, and then facilitate the base body placed between the clamping plate 204, when the base body is placed between the clamping plate 204, slide connecting cylinder 203, when the clamping plate 204 and the connecting cylinder 203 hinge point movement through the limiting hole 206 and move to the side of the close, the inner wall of the limiting hole 206 gradually against the clamping plate 204 and force the clamping plate 204 rotate close to each other, forming a containing cavity 201 on the base body resistance clamping;

[0047] When the device will be fixed after the base body clamping, slide the clamping member 3 force the base body and the cylindrical component contact, through the welding head 101 on both sides close to the welding head 101 welding, in the process, through the drive motor 102 drive fixed cylinder 202 slowly rotating drive base body rotation, and through the cooperation of the clamping member 3 clamping cylindrical component, in the process of cylindrical component and base body between the resistance, so that the friction between the cylindrical component and the base body, through the friction between the two, so that the drive motor 102 drive base body rotation at the same time can also drive the cylindrical component movement, so that the two parts are not welded gradually rotating close to the welding head 101, and then complete the annular welding.

[0049] The clamping cavity 301 is provided on the mounting plate 302, and the mounting plate 302 is slidingly provided with a shielding plate 303.

The inner wall of the hole limits the side wall of the rod, so that the shielding plate 303 can only move close to or away from the mounting plate 302 along the axis direction of the clamping cavity 301. In the process, the connecting spring 304 is also shielded by the rod, so that the connecting spring 304 can only be elastically deformed along the axis direction of the rod, thereby increasing the stability of the connecting spring 304 during deformation;

[0051] When it is necessary to install the cylindrical component, the cylindrical component is inserted into the clamping cavity 301 from the side close to the connecting cylinder 203 of the clamping cavity 301, in the process, the cylindrical component abuts against the elastic plates 306, and the elastic plates 306 abut against and clamp the cylindrical component, and in the process of abutting, the shielding plate 303 is pushed away from the mounting plate 302, so that the connecting spring 304 is stretched, at this time, the sliding mounting plate 302 drives the cylindrical component to contact the base body, because the connecting spring 304 is in a stretched state, a force towards the connecting cylinder 203 direction is generated on the shielding plate 303, so that the cylindrical component abuts against the base body, and at this time, the sliding of the connecting cylinder 203 in the fixed cylinder 202 reaches the maximum value, so that the abutting of the cylindrical component can limit the sliding of the connecting cylinder 203 in the fixed cylinder 202, in the process, the sliding of the mounting plate 302 can be limited by the bolt or other components, through the above setting, the clamping piece 3 can clamp the cylindrical component at the same time, and the sliding of the connecting cylinder 203 can be limited during welding, thereby increasing the practicability of the device, and through the stretching of the connecting spring 304, the cylindrical component and the base body can be forced to be in an abutting state, compared with only a contact state, the contact between the two is more close, thereby facilitating the strength and stability after the two are welded, and increasing the welding effect of the device;

[0052] Compared with rotating the cylindrical component between the elastic plates 306 by overcoming friction, when the driving motor 102 drives the fixed cylinder 202 to rotate, because the limiting plate 305 is rotatably connected with the shielding plate 303, and the elastic plates 306 are installed on the limiting plate 305, the limiting plate 305 also rotates on the shielding plate 303 when the cylindrical component is driven to rotate, so that the cylindrical component can more easily rotate with the base body, thereby increasing the feasibility of the device, and the damage to the cylindrical component during rotation is also smaller, thereby increasing the practicability of the device.

[0063] A platform is formed on the mounting plate 302, when the inserting plate 6 is rotated to a state capable of being inserted into the insertion slot 7, the plate body is arranged on the upper surface of the platform, the rotation of the inserting plate 6 in use is limited by the support of the platform and the gravity of the inserting plate 6 itself, so that the inserting plate 6 can be kept at a position in contact with the pressure plate 9, an electric push rod can be arranged below the platform to push the inserting plate 6, which facilitates the rotation of the inserting plate 6 to be out of contact with the pressure plate 9, and the feasibility of the device is increased.

[0064] Through the above arrangement, the sliding of the mounting plate 302 is limited while the positioning plate 401 can be positioned, and the applicability of the device is increased.

[0065] As shown in Figure 5 part of the structure on the connecting cylinder 203 is disclosed, in some embodiments, the connecting cylinder 203 is provided with an extension column 14, a suction cup 15 is installed at the free end of the extension column 14, and the suction cup 15 is used to generate an attractive force to the base body, when the base body is installed, since the clamping plates 204 are initially in an open state, the base body cannot be effectively fixed, the operator needs to hold the base body with hands or with the help of a mechanical hand, and press the base body onto the suction cup 15 to preliminarily fix the base body, so that the operator does not need to hold the base body until the clamping plates 204 are closed, and since the suction cup 15 is made of rubber and can be deformed, when the clamping plates 204 clamp the base body, the position of the base body can be corrected by contact, so that the axis of the base body is collinear with the axis of the accommodating cavity 201, and the practicability of the device is increased.

[0066] As shown in Figure 5As shown, the part structure on the clamping plate 204 is disclosed, in some embodiments, the clamping plate 204 is provided with an expansion plate 16 at the free end, when the base body is clamped by the clamping plate 204, the projection of the expansion plate 16 along the axis direction of the accommodating cavity 201 is located on the base body, when the clamping plate 204 clamps the base body completely, the expansion plate 16 is located at the opening side, when the base body is fixed, the suction cup 15 is located at the close side and contacts the base body, and the displacement of the base body in this direction is limited, and the expansion plate 16 is located at the opening side and contacts the base body, since the diameter of the base body is larger than the diameter of the cylindrical component, when the two are in pre-contact, the shape is inverted T, and the welding head 101 only needs to extend to the gap at the connection of the two, and the sum of the diameters of the expansion plate 16 and the cylindrical component is smaller than the diameter of the base body, so the part of the expansion plate 16 contacting the base body does not extend to the connection between the cylindrical component and the base body, and thus does not affect welding, the displacement of the base body in this direction is limited, the movement of the base body is further limited, and the stability of the base body during welding is increased.

[0067] As shown in the drawings, Figure 6 As shown, in some embodiments, the guide groove 17 is arranged in the fixing cylinder 202, and the guide block 18 is arranged on the connecting cylinder 203 and slidably arranged in the guide groove 17, when the connecting cylinder 203 slides, the guide block 18 slides in the guide groove 17, and the inner wall of the guide groove 17 shields and limits the side wall of the guide block 18, so that the connecting cylinder 203 can only slide along the axis direction of the fixing cylinder 202 and cannot rotate in the fixing cylinder 202, thereby increasing the stability of the connecting cylinder 203 during sliding, and ensuring that the connecting cylinder 203 can smoothly rotate with the fixing cylinder 202 during rotation of the fixing cylinder 202, without slipping, and increasing the practicability of the device.

[0068] The components in the present application can not only be fully automated by the cooperation of the mechanical hand, but also can be manually operated to complete welding or loss prevention in time when the mechanical hand program or sensor fails, thereby increasing the practicability of the device.
