It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0027] The following describes, with reference to the accompanying drawings, some embodiments of an automobile bracket welding device provided by this utility model. Example

[0028] Combination Figure 1-6As shown, the present invention provides a car bracket welding device, comprising: a welding machine body 100 and a clamping assembly 200; the welding machine body 100 includes a control box 101 fixedly installed at its front end; the clamping assembly 200 includes a worktable 201 fixedly installed at the upper end of the welding machine body 100, a slide groove 202 extending through both sides of the worktable 201, a first toothed plate 203 fixedly installed at the bottom of the slide groove 202, movable frames 204 movably arranged within the slide groove 202, a second toothed plate 205 fixedly installed at the bottom of the movable frame 204, a fixed seat 206 movably installed within the movable frame 204, an electric cylinder 207 fixedly installed on one side of the fixed seat 206, a pressure plate 208 movably installed within the movable frame 204, and a movable plate 209 movably installed on one side of the movable frame 204; the movable frame 204 also has mounting openings 210 on both sides, and springs 211 are fixedly installed within the mounting openings 210, with the tops of the springs 211... Fixed to the lower end of the movable plate 209, the movable frame 204 also has a restraint opening 212. A restraint rod 213 is fixedly installed at the center of the bottom of the movable plate 209, and the restraint rod 213 is movably matched and installed in the restraint opening 212. The upper and lower sides of the pressure plate 208 are also fixedly installed with fixing sleeves 214. The upper and lower sides of the movable frame 204 are both provided with threaded holes 215. Locking screws 216 are movably installed in the threaded holes 215, and one side of the locking screws 216 is movably installed. The movable frame 204 is installed in the fixed sleeve 214. A slot 217 is provided on one side of the movable frame 204. A block 218 is fixedly installed on one side of the fixed seat 206 and is movably matched and installed in the slot 217. A first friction pad 219 is fixedly installed on both sides of the movable frame 204. A second friction pad 220 is fixedly installed on one side of the pressure plate 208. A clamping plate 221 is fixedly installed at the front end of the electric cylinder 207. The electric cylinder 207 is electrically connected to the control box 101.

[0029] Specifically, the automotive bracket welding device is used for welding plates together during automotive bracket processing. The movable frame 204 installed in the sliding grooves 202 on both sides of the worktable 201 in the welding machine body 100 can freely adjust the horizontal position and vertical height of the electric cylinder 207 according to the clamping position requirements during workpiece welding by freely moving horizontally within the sliding grooves 202 and freely lifting and lowering the fixed seat 206 within the movable frame 204. This improves the flexibility and adaptability of adjusting the clamping position during automotive bracket welding. Furthermore, the number of movable frames 204 used within the slide 202 can be freely assembled and disassembled according to usage requirements to ensure clamping tightness during welding. The first toothed plate 203 within the slide 202 is mainly used for meshing connection with the second toothed plate 205 at the bottom of the movable frame 204 to ensure the stability of the movable frame 204 within the slide 202. The movable plate 209 installed on one side of the movable frame 204, and the spring 211 fixedly connected between the bottom of the movable plate 209 and the movable frame 204, are mainly used for pressing the movable frame 204 to secure it. The second toothed plate 205 at the bottom of the movable frame 204 is tightly pressed against the upper end of the first toothed plate 203 to ensure the stability of the movable frame 204 within the slide groove 202. The restraining rod 213 at the center of the movable plate 209 is installed in the restraining opening 212 at the lower end and is mainly used to restrain the movable plate 209 to ensure its stability during compression adjustment. The pressure plate 208, tightened by the locking screw 216 on the movable frame 204, is mainly used to fasten the fixed seat 206 inside the movable frame 204, thereby ensuring the stability of the fixed seat 206 and its outer electric motor. The stability of cylinder 207 is enhanced by the second friction pad 220 at the outer end of pressure plate 208 and the first friction pads 219 on both sides of movable frame 204, which are positioned on both sides of fixed seat 206 during clamping, thereby increasing the friction after clamping. The stability of fixed seat 206 after clamping is achieved by the slot 217 on one side of movable frame 204, which mainly restrains the locking block 218 at the outer end of fixed seat 206, thereby restraining the position of fixed seat 206 and preventing its rotation. The clamping plate 221 at the front end of electric cylinder 207 is mainly used for clamping and pressing workpieces.

[0030] Working principle and usage process of this utility model:

[0031] When the workpiece is clamped at the upper end of the workbench 201, the horizontal position of the electric cylinder 207 can be adjusted according to the clamping position. When adjusting the horizontal position of the electric cylinder 207, the movable frame 204 is first pulled upward so that the upper part of the slide 202 presses down on the movable plate 209 at one end of the movable frame 204. After the movable plate 209 is pressed down, it will compress the spring 211 at the bottom and move downward. After the movable plate 209 is pressed down and moved downward, the entire movable frame 204 will be raised. After the movable frame 204 is raised, the second toothed plate 205 at the bottom will disengage from the engagement with the first toothed plate 203 at the bottom, and then the entire movable frame 204 can move horizontally freely within the slide 202. After the entire movable frame 204 moves to a suitable position, the entire movable frame 204 is lowered so that the spring 211 at the bottom of the movable plate 209 can be compressed. 11. The second toothed plate 205 at the bottom is re-engaged and pressed against the upper end of the first toothed plate 203 to ensure the stability of the overall horizontal position of the movable frame 204 in the slide 202 after adjustment. When it is necessary to adjust the height of the electric cylinder 207 on the movable frame 204, first loosen the locking screws 216 on the upper and lower sides of the movable frame 204 in sequence. Then, the fixed seat 206 and the electric cylinder 207 can be moved up and down freely in the movable frame 204 to move them to a suitable height. After moving to a suitable height, the locking screws 216 on the upper and lower sides are tightened again to press and fix the fixed seat 206 and the electric cylinder 207 in the movable frame 204, thereby completing the free adjustment of the height of the electric cylinder 207. At the same time, the number of movable frames 204 on both sides of the worktable 201 can also be freely increased or decreased as needed.

[0032] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
