[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains; the terms used herein in the specification of this invention are for the purpose of describing specific embodiments only and are not intended to limit this invention; the term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0038] like Figures 1 to 6 As shown, the present application provides a fixture for welding electric tricycle accessories, comprising a base plate 100, a long frame plate 130 and a short frame plate 131, and also comprising a cleaning clamping assembly 200;

[0039] The cleaning clamping assembly 200 includes a moving device 210, a telescopic soft bag 220 and an air inlet pipe 230;

[0040] The moving device 210 is located in the fixed frame 110 , and a cylinder 211 is fixed on the moving device 210 , and a connecting plate 212 is fixed on the telescopic end of the cylinder 211 ;

[0041] The telescopic soft bag 220 is fixed on the connecting plate 212, and a cleaning seat 240 is fixed on the free end of the telescopic soft bag 220. There is cleaning cotton on the inner side of the cleaning seat 240. The air inlet pipe 230 is used to inflate the telescopic soft bag 220 to drive the cleaning seat 240 to clean the connection between the long plate 130 and the short plate 131 of the frame.

[0042] It is worth noting that, in the initial state, the first welded portion is cleaned first, and then the cleaning clamping assembly 200 is used to clamp one end of the frame short plate 131 .

[0043] Specifically, if Figures 3 to 6 As shown, the cleaning seat 240 is a U-shaped frame and a clamping soft bag 241 is fixed on its inner side surface, an air pump is fixed on the air inlet pipe 230, and the air pump is fixed on the connecting plate 212. There are multiple air outlet ends on the air inlet pipe 230, one air outlet end extends into the telescopic soft bag 220, and one air outlet end extends into the clamping soft bag 241. The connection between the air outlet end of the air inlet pipe 230 and the telescopic soft bag 220 and the clamping soft bag 241 is airtightly fixed, the cleaning cotton is fixed to the inner side surface of the clamping soft bag 241, and the cleaning cotton is in contact with the surface of the frame short plate 131.

[0044] It is worth noting that the cleaning cotton has the same shape as the cleaning seat 240. After the clamping soft bag 241 is expanded, the cleaning cotton contacts the three surfaces of the frame short plate 131, and can clean the three surfaces of the frame short plate 131 at the same time, with high cleaning efficiency.

[0045] Specifically, if Figure 8 As shown, a supporting plate 2201 is fixed on the cleaning seat 240 near the cylinder 211, and a soft bag 221 is fixed on the bottom of the supporting plate 2201;

[0046] A cleaning cloth is fixed to the bottom of the soft bag 1 221, a branch pipe 231 is fixed to the air inlet pipe 230, and a branch pipe 231 is fixed to the free end of the branch pipe 231. The branch pipe 231 extends into the soft bag 1 221, and the connection between the branch pipe 231 and the soft bag 1 221 is airtight and fixed;

[0047] The cleaning cloth on the soft bag 1 221 is in contact with the surface of the long plate 130 of the frame.

[0048] It is easy to understand that the soft bag 1 221 is used to clean the connection between the long frame plate 130 and the short frame plate 131 , and the contact force between the cleaning cloth and the long frame plate 130 is increased by letting air into the soft bag 1 221 .

[0049] Specifically, if Figures 4 to 6 As shown, two parallel soft bags 242 are fixed to the inner bottom of the cleaning seat 240. A cleaning wipe is fixed on each soft bag 242 near the short plate 131 of the frame, and the cleaning wipe can contact the lower surface of the short plate 131 of the frame;

[0050] Two ventilation tubes 232 are fixed on the air inlet pipe 230 . The ventilation tubes 232 are provided with micro valves for controlling the air intake amount in the second soft bag 242 . One ventilation tube 232 extends into one second soft bag 242 .

[0051] It is worth noting that after a period of time, the micro valve of the vent pipe 232 opens to start the intake of air into the vent pipe 232 , inflating the soft bag 242 so that the cleaning wipe contacts the frame short plate 131 , thereby facilitating comprehensive cleaning of the frame short plate 131 .

[0052] Specifically, if Figures 1 to 8 As shown, a second liquid bladder 2411 is fixed on the clamping bladder 241 near the short plate 131 of the frame, and a cleaning cotton is fixed on the second liquid bladder 2411. A liquid outlet is opened at the bottom of the second liquid bladder 2411. The second liquid bladder 2411 is filled with cleaning liquid, and the cleaning liquid overflows from the liquid outlet onto the cleaning cotton. The cleaning cotton is used to clean the three surfaces of the short plate 131 of the frame.

[0053] A third liquid bladder 2421 is fixed to the second bladder 242 near the short frame plate 131. A liquid outlet is provided on the top of the third liquid bladder 2421. Cleaning liquid is injected into the third liquid bladder 2421. The cleaning liquid overflows from the outlet onto the cleaning cloth, and the remaining surface of the short frame plate 131 is cleaned with the cleaning cotton.

[0054] A liquid soft bag 222 is fixed on the soft bag 221 near the long plate 130 of the frame. A liquid outlet is opened at the bottom of the liquid soft bag 222. Cleaning liquid is filled in the liquid soft bag 222. The cleaning liquid overflows from the liquid outlet onto the cleaning cloth, and the cleaning cloth is used to clean the surface of the long plate 130 of the frame.

[0055] Specifically, if Figures 1 to 7 As shown, there are two groups of cleaning clamping assemblies 200 , one cleaning clamping assembly 200 is located in the fixed frame 110 , and the other group of cleaning clamping assemblies 200 is located in the movable frame 120 .

[0056] It is worth noting that, in the initial state, one end of the frame short plate 131 is cleaned by a set of cleaning and clamping assemblies 200 , and then the one end of the frame short plate 131 is clamped by the cleaning and clamping assembly 200 .

[0057] In the above embodiment, one end of the short frame plate 131 is brought into contact with a long frame plate 130, and air is introduced into the air intake pipe 230 by the air pump, so that the telescopic soft bag 220 expands downward and drives the cleaning seat 240 close to the short frame plate 131, until the cleaning cloth on the liquid soft bag 1 222 contacts the long frame plate 130, and the cleaning cotton on the liquid soft bag 2 2411 contacts three surfaces of the short frame plate 131, then the micro valve on the vent pipe 232 is opened to inflate the soft bag 2 242 so that the cleaning cotton on the liquid soft bag 3 2421 contacts the remaining surface of the short frame plate 131, fully wrapping the short frame plate 131, and continuing to introduce air into the air intake pipe 230 to squeeze the cleaning liquid to cause it to overflow, thereby cleaning the welded joint between the short frame plate 131 and the long frame plate 130, and at the same time, clamping and fixing the short frame plate 131 to facilitate welding the cleaned portion at the other end of the short frame plate 131;

[0058] After the welding of one end is completed, the connecting plate 212 is pushed to move by the cylinder 211 to clean the connection between the short plate 131 of the frame and the long plate 130 of the frame at the clamping end, and the other parts of the short plate 131 of the frame are cleaned synchronously at the same time. The frame can be cleaned while welding, which reduces the subsequent cleaning burden and improves processing efficiency.

[0059] In some embodiments of the present application, Figures 1 to 7 As shown, a fixed frame 110 is fixed on the bottom plate 100, a movable frame 120 is movably connected to the bottom plate 100, and there are two frame long plates 130, one frame long plate 130 is located on the fixed frame 110, and the other frame long plate 130 is located on the movable frame 120;

[0060] An adjusting portion 140 is fixed on the bottom plate 100 near the movable frame 120. The adjusting portion 140 is used to adjust the distance between the movable frame 120 and the fixed frame 110, so as to facilitate welding of the long frame plates 130 with different spacing requirements.

[0061] Specifically, if Figures 1 to 7 As shown, a fixing plate 141 is fixed on the bottom plate 100, a through hole is opened on the fixing plate 141, and an internal thread is opened in the through hole. A threaded rod 142 is movably connected to the movable frame 120, and the threaded rod 142 has an external thread used in conjunction with the internal thread;

[0062] The remaining end of the threaded rod 142 extends into the through hole and extends to one side of the fixing plate 141 , and a rotating disk 143 is fixed on the remaining end of the threaded rod 142 .

[0063] It is easy to understand that a threaded connection is formed between the threaded rod 142 and the through hole, and the movable frame 120 can be pushed toward the fixed frame 110 by rotating the threaded rod 142 .

[0064] In the above embodiment, the threaded rod 142 is driven to rotate by rotating the rotating disk 143. As the threaded rod 142 rotates, the movable frame 120 is pushed closer to the fixed frame 110, and the distance between the two long frame plates 130 is adjusted. This can adapt to the welding of various specifications of short frame plates 131 and long frame plates 130, thereby increasing the efficiency of use.

[0065] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. A person skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
