[0017] Step 2: Place the middle position of the handle on the support rod, so that the bottom of the handle is supported by the support rod and the support rod. Then, use the electric telescopic rod to drive the pressing rod to clamp both ends of the handle.

This allows for precise and stable adjustment of the handle position, thus preventing welding deformation when welding the handle to the electronically controlled steering wheel.

[0022] 2. During welding, turn on the suction fan to draw harmful gases and fumes generated during welding into the fixed box through the suction pipe. After being filtered and adsorbed by the filter screen and activated carbon adsorption plate, they are discharged, which can prevent pollution of the working environment. When using the handwheel, the transmission component can drive the support shaft to rotate back and forth automatically, which in turn drives the rubber ring to hit the filter screen back and forth, shaking off the fumes and dust on the filter screen, improving the efficiency of handling harmful gases and fumes during welding, thereby better protecting the working environment.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] As mentioned in the background section, existing technologies for welding handlebars to electronic steering wheels are prone to deformation due to unstable clamping, and the direct emission of harmful gases and fumes during the welding process pollutes the working environment. This invention proposes a welding fixture and method for a go-kart handlebar bracket that prevents welding deformation. Example

[0032] Reference Figures 1 to 6 A welding fixture for a go-kart handlebar bracket designed to prevent welding deformation includes a base 1 and a fixing plate 2 mounted on the base 1. In order to control the electrical components described herein, a control box 3 is mounted on the base 1.

[0033] Two sets of identical dust collection components are installed on the fixed plate 2;

[0034] The top of the base 1 is provided with an electronically induction steering wheel clamping assembly and a handle clamping assembly, wherein the electronically induction steering wheel clamping assembly is used to clamp the electronically induction steering wheel 7, and the handle clamping assembly is used to clamp the handle 23.

[0035] The electronically controlled steering wheel clamping assembly includes a support block 4 mounted on the top of the base 1. Electric push rods 5 are mounted on both sides of the front of the support block 4. Clamping rods 6 are mounted on the output ends of the electric push rods 5 on both sides. The clamping rods 6 on both sides are higher than the support block 4. The bottom of the electronically controlled steering wheel 7 is attached to the support block 4, and the front and rear sides of the electronically controlled steering wheel 7 are in contact with the opposite sides of the two sets of clamping rods 6 respectively. When the electronically controlled steering wheel 7 is placed on the support block 4, the clamping rods 6 are driven by the electric push rods 5 to clamp it.

[0036] The handle clamping assembly includes a horizontally opened slide groove 8 on the base 1. Two sets of identical slides 9 are slidably connected to the slide groove 8. Both sets of slides 9 are screwed onto a lead screw 10. A connecting shaft 11 is provided at the end of the lead screw 10 away from the support block 4. The connecting shaft 11 is rotatably mounted on a bearing seat 12, which is mounted on the base 1. In order to prevent the handwheel 14 from being too close to the base 1 and affecting the operator's operation, a fixed shaft 13 is rotatably mounted on the bearing seat 12 above the connecting shaft 11. The handwheel 14 is provided on the side of the fixed shaft 13 away from the support block 4. A belt drive assembly 15 is connected between the connecting shaft 11 and the fixed shaft 13. By rotating the fixed shaft 13, the belt drive assembly 15 can drive the connecting shaft 11 to rotate. Rotating the handwheel 14 causes the lead screw 10 to rotate, which moves the slides 9, thereby causing the handle 23 to contact the electronically sensed steering wheel 7. Compared with using an electric motor to move the handle 23, it is easier to adjust the position of the handle 23 more accurately and stably.

[0037] One set of slides 9 has a fixed rod 16 on its top, and another set of slides 9 has a supporting long rod 17 on its top. The supporting long rod 17 is connected to the fixed rod 16. Supporting short rods 18 are evenly arranged on the side of the fixed rod 16 near the support block 4. Connecting rods 19 are provided between adjacent supporting short rods 18 and between supporting short rods 18 and supporting long rods 17 to improve the stability of supporting long rods 17 and supporting short rods 18. The bottom middle position of the handle 23 is in contact with the supporting long rod 17, and the front and rear sides of the bottom of the handle 23 are in contact with the supporting short rods 18. By placing the middle position of the handle 23 on the supporting long rod 17, the bottom of the handle 23 is supported by the supporting long rod 17 and supporting short rods 18, which better fits the size of the handle 23 and increases the support area of ​​the handle 23.

[0038] Mounting rods 20 are provided on both the front and rear sides of the fixing rod 16. Electric telescopic rods 21 are provided on both mounting rods 20. The output end of the electric telescopic rods 21 is provided with a pressing rod 22. The pressing rod 22 is in contact with both ends of the front and rear sides of the handle 23. The pressing rod 22 is driven by the electric telescopic rod 21 to clamp both ends of the front and rear sides of the handle 23, which can increase the clamping area of ​​the handle 23 and thus stably clamp the handle 23.

[0039] The dust collection assembly includes a fixed box 24 located on the rear side of the fixed plate 2. The fixed box 24 is connected to a dust collection pipe 29 that passes through the fixed plate 2. A suction fan 25 is located on the rear side of the fixed box 24. An activated carbon adsorption plate 27 and a filter screen 28 are arranged sequentially from back to front inside the fixed box 24. During the welding process, the suction fan 25 is turned on, so that the harmful gases and fumes generated during the welding process are sucked into the fixed box 24 through the dust collection pipe 29, filtered and adsorbed by the filter screen 28 and the activated carbon adsorption plate 27, and then discharged.

[0040] To facilitate maintenance of the internal structure of the fixed box 24, a box door 26 is provided on the side of the fixed box 24.

[0041] The bottom of the fixed box 24 is connected to a support shaft 30 via bearings. A connecting frame 31 is provided at the top of the support shaft 30, and rubber rings 32 are evenly arranged on the connecting frame 31. The support shaft 30, connecting frame 31 and rubber rings 32 are all located on the front side of the filter screen 28. A gear 33 is provided at the bottom of the support shaft 30. The gear 33 is meshed with a rack 34, and the rack 34 is laterally slidably connected to the rear side of the fixed plate 2. A spring 35 is provided between the rack 34 and the fixed plate 2. A rotating wheel 36 is provided on the side of the rack 34 away from the spring 35. The rotating wheel 36 is connected to the transmission assembly. The spring 35 is used to reset the rack 34. When the rack 34 moves, it can drive the gear 33 to rotate, which in turn drives the connecting frame 31 and rubber rings 32 to rotate through the support shaft 30. Example

[0042] Reference Figure 1 , Figure 2 and Figure 6 The transmission assembly includes a rotating shaft 38 and a transmission shaft rotatably mounted on the base 1 via bearings. A cam 37 is mounted on the rotating shaft 38, contacting the rotating wheel 36. A belt drive assembly 39 connects the rotating shaft 38 and the transmission shaft. A driven bevel gear 40 is mounted on the transmission shaft, and a driving bevel gear 41 meshes with the driven bevel gear 40. The driving bevel gear 41 is mounted on the connecting shaft 11. Each time the handwheel 14 is rotated, causing the slide 9 to move laterally, the driving bevel gear 41 drives the driven bevel gear 40 to rotate, causing the transmission shaft to rotate via the belt drive assembly 39, which in turn drives the cam 37 to rotate. The cam 37 presses against the rotating wheel 36, causing the rack 34 to move laterally back and forth, which in turn causes the rubber ring 32 to strike the filter screen 28 back and forth, shaking off the dust and fumes from the filter screen 28. This improves the efficiency of treating harmful gases and fumes during welding, thus better protecting the working environment.

[0043] The rest of the structure is the same as in Example 1.

[0044] A welding method for a welding fixture for a go-kart handlebar bracket that prevents welding deformation, using the welding fixture for a go-kart handlebar bracket that prevents welding deformation as described in Example 2, specifically includes the following steps:

[0045] Step 1: Place the electronically controlled steering wheel 7 on the support block 4, and use the electric push rod 5 to drive the clamping rod 6 to clamp it.

[0046] Step 2: Place the middle position of the handle 23 on the support rod 17, so that the bottom of the handle 23 is supported by the support rod 17 and the support rod 18. Then, drive the pressing rod 22 through the electric telescopic rod 21 to clamp both ends of the handle 23. Then, turn the handwheel 14 to make the lead screw 10 rotate and drive the slide 9 to move, so that the handle 23 can contact the electronic induction steering wheel 7. Then, welding can be performed by the welding robot.

[0047] Step 3: During the welding process, turn on the suction fan 25 so that the harmful gases and fumes generated during the welding process are sucked into the fixed box 24 through the suction pipe 29, and discharged after being filtered and adsorbed by the filter screen 28 and the activated carbon adsorption plate 27.

[0048] Step 4: After welding, release the electronically controlled steering wheel 7 by clamping rod 6, release the handle 23 by squeezing rod 22, and then turn handwheel 14 to move the slide 9 away from the support block 4. When turning handwheel 14, the transmission component can drive the support shaft 30 to rotate back and forth, thereby driving the rubber ring 32 to hit the filter screen 28 back and forth.

[0049] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
