Description

Technical Field

[0001] The invention relates to the technical field of welding auxiliary equipment, and in particular to welding auxiliary equipment for an anti-collision bracket of an electric tricycle. Background Art

[0002] The electric tricycle anti-collision bracket is a safety device installed on the electric tricycle. The main function of the electric tricycle anti-collision bracket is to absorb the impact force when the vehicle collides, protecting the safety of the driver and the vehicle. It can also prevent the tricycle from rolling over when turning, reducing personal and property losses. Figure 8 The electric tricycle anti-collision bracket shown is mainly composed of a crossbeam and two side beams. During processing, the two side beams need to be welded to the crossbeam. However, during processing, impurities will adhere to the surface of the side beams. If they are not cleaned in time, the quality after welding will be affected. Summary of the invention

The base plate is arranged on the workbench and two positioning plates 1 are symmetrically arranged on both sides thereof. The vertical plate is arranged on the base plate and a positioning plate 2 is arranged on the top thereof. The horizontal plate is perpendicularly arranged on the vertical plate and L-shaped plates are symmetrically arranged on both sides thereof.

[0008] Preferably, the limiting mechanism includes a toggle clamp, a cylinder, a pressure plate and a connecting plate. The toggle clamps are provided with two and are symmetrically arranged on both sides of the workbench. The cylinder body of the cylinder is provided on the support frame and the end of the piston rod thereof is hinged with a pressure plate. One end of the connecting plate is hinged to the pressure plate, and the other end is hinged to the cylinder body of the cylinder.

[0009] Preferably, the cleaning mechanism includes a pressing rod, a spring, an arc-shaped plate and a torsion spring. The pressing rod is slidably connected to the second positioning plate and the vertical plate. The pressing rod is connected with a lifting plate through a fixing plate. The spring is sleeved on the pressing rod and located below the fixing plate. Installation plates are symmetrically arranged on both sides of the lifting plate. A fixed shaft is arranged in the installation plate. Arc-shaped plates are rotatably connected to the upper and lower sides of the fixed shaft.

The cleaning mechanism 5 is arranged on the positioning frame 2 and is used to clean the welding end faces of the side beams 62 on both sides of the anti-collision bracket 6 under the action of the gravity of the cross beam 61 of the anti-collision bracket 6.

[0024] It should be noted that the positioning frame 2 includes a bottom plate 21, a vertical plate 23 and a cross plate 25. The bottom plate 21 is arranged on the workbench 1, and two first positioning plates 22 are symmetrically arranged on both sides thereof.

Both the first positioning plate 22 and the second positioning plate 24 are of a "U" - shaped structure and are arranged with the opening facing upwards.

[0025] In addition, the limiting mechanism 4 includes an elbow clamp 41, a cylinder 42, a pressing plate 43 and a connecting plate 44. Two elbow clamps 41 are provided and symmetrically arranged on both sides of the workbench 1. The cylinder body of the cylinder 42 is arranged on the support frame 3, and the end of its piston rod is hinged with a pressing plate 43. One end of the connecting plate 44 is hinged with the pressing plate 43, and the other end is hinged with the cylinder body of the cylinder 42.

[0026] In addition, the cleaning mechanism 5 includes a pressure rod 51, a spring 53, an arc plate 55 and a torsion spring 553. The pressure rod 51 is slidably connected to the positioning plate 24 and the vertical plate 23. The pressure rod 51 is connected to the lifting plate 52 through the fixed plate 511. The spring 53 is sleeved on the pressure rod 51 and is located at the lower side of the fixed plate 511. Mounting plates 54 are symmetrically provided on both sides of the lifting plate 52. A fixed shaft 541 is provided in the mounting plate 54. The upper and lower sides of the fixed shaft 541 are rotatably connected with the arc plate 55. The end of the arc plate 55 is rotatably provided with a guide roller 552. A cleaning brush 551 is provided on the inner side of the arc plate 55. The torsion spring 553 is sleeved on the fixed shaft 541. One end of the torsion spring 553 is connected to the arc plate 55, and the other end is connected to the mounting plate 54. An L-shaped frame 56 is provided at the bottom of the mounting plate 54. A fixed frame 57 is provided at the end of the L-shaped frame 56. A cleaning roller 58 is provided in the fixed frame 57.

[0027] Specific implementation and principle:

[0028] During operation, the side beams 62 of the two anti-collision brackets 6 are respectively placed in the positioning plates 22 on the bottom plate 21, and pushed toward the direction of the L-shaped plate 26 at the end of the transverse plate 25. When the side beams 62 of the anti-collision bracket 6 contact the guide rollers 552 on the arc plate 55, the arc plate 55 is squeezed toward both sides, and the side beams 62 enter between the two arc plates 55. Under the action of the torsion spring 553, the arc plate 55 is reset and closed, so that the cleaning brush 551 on the inner side of the arc plate 55 contacts the side beams 62. When the side beams 62 contact the L-shaped plate 26, the pushing of the side beams 62 is stopped, and then the side beams 62 are fixed by the toggle clamps 41.

[0029] Then, the cross beam 61 of the anti-collision bracket 6 is placed in the positioning plate 24 at the top of the vertical plate 23, and then the cross beam 61 is pressed downward, and the cross beam 61 presses the pressure rod 51 to move downward, so that the lifting plate 52 moves downward, and the cleaning brush 551 in the arc plate 55 cleans the side welding surface of the top of the side beam 62, and at the same time, the fixing frame 57 on the side of the L-shaped plate 26 cleans the side welding surface of the bottom of the side beam 62 through the cleaning roller 58;

[0030] Next, the piston rod of the cylinder 42 drives the pressing plate 43 and the connecting plate 44 to rotate, and the pressing plate 43 presses the crossbeam 61 of the anti-collision bracket 6 onto the measurement surface;

[0031] Then, the cross beam 61 and the side beam 62 of the anti-collision bracket 6 are welded.

[0032] In summary, the present application fixes and limits the cross beam 61 and the side beam 62 of the anti-collision bracket 6 through the elbow clamp 41 and the cylinder 42 of the limiting mechanism 4. When moving, the side beam 62 squeezes the arc plate 55 toward both sides, and the side beam 62 enters between the two arc plates 55. Under the action of the torsion spring 553, the arc plate 55 is reset and closed, so that the cleaning brush 551 on the inner side of the arc plate 55 contacts the side beam 62, and the pressure rod 51 is pressed by moving the cross beam 61 downward, so that the cleaning brush 551 and the cleaning roller 58 on the arc plate 55 clean the side welding surface of the side beam 62 of the anti-collision bracket 6, thereby improving the welding quality of the cross beam 61 and the side beam 62 of the anti-collision bracket 6.

[0033] The above-described embodiments of the present invention do not constitute a limitation on the protection scope of the present invention. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
