[0026] The utility model will be further explained in detail in combination with the drawings.

[0027] Please refer to Figures 1-4 As shown in the figure, in the embodiment, a point welding auxiliary clamping device for coupling production is provided, which comprises a base 1.

[0028] As Figure 1 , 2As shown in Figure 4, in this embodiment, the base 1 has slide rails 101 on both sides of its top. A horizontal adjusting screw 102 is longitudinally installed inside the slide rails 101. A support frame 2 is installed on the top of the slide rails 101, and a top plate 201 is installed on the top of the support frame 2. A drive wheel 204 is located at the center of the top of the top plate 201, and a handle 206 is installed at the center of the drive wheel 204. A chain 205 is sleeved on the surface of the drive wheel 204. Driven wheels 203 are located on both sides of the top of the top plate 201. A height adjusting screw 202 is installed inside the support frame 2, and a clamping plate 3 is installed between the support frames 2. The support frame 2 is divided into left and right sections, and each support frame 2 has a height adjusting screw 202. When the product is placed on the clamping plate 3, the height adjusting screw 202 passes through both sides of the clamping plate 3 and engages with the threaded holes. Rotating the height adjustment screw 202 drives the clamping plate 3 to move up and down, thereby adjusting the product height. Two drive wheels 204 are mounted on the handle 206, one high and one low, coaxially arranged. Rotating the handle 206 drives both drive wheels 204 to rotate simultaneously. These two drive wheels 204 are connected to two driven wheels 203 (one on the left and one on the right) via a chain 205. Each drive wheel 204 drives one driven wheel 203 to rotate, achieving simultaneous rotation of both driven wheels 203. The two driven wheels 203 are respectively mounted on the corresponding height adjustment screws 202, causing the two height adjustment screws 202 to rotate synchronously and engage with the threaded holes on both sides of the clamping plate 3, providing upward force from both sides simultaneously. This prevents the clamping plate 3 from tilting during the ascent due to left-right force deviation, thus avoiding any impact on the installed product.

[0029] like Figure 1 , 3 As shown, in this embodiment, a second clamping plate 301 is provided above the first clamping plate 3. A clamping screw 303 is vertically installed on one side of the first clamping plate 3. A threaded sleeve 304 is sleeved between the surface of the second clamping plate 301 and the clamping screw 303. The threaded sleeve 304 is installed on the second clamping plate 301 and extends from the surface of the second clamping plate 301 by a certain distance, thereby extending the contact length between the clamping screw 303 and the second clamping plate 301. This makes the force on the second clamping plate 301 at the threaded sleeve 304 more dispersed and more stable, and the threads are not easily damaged after long-term use. The bottom of the clamping screw 303 is embedded in the first clamping plate 3, so the clamping screw 303 can be rotated without falling off the first clamping plate 3. By rotating the clamping screw 303, the surface threads and the threaded sleeve 304 engage, causing the second clamping plate 301 to press down, thereby cooperating with the first clamping plate 3 to clamp and fix the product between them.

[0030] like Figure 1 , 3As shown, the top of the first clamp plate 3 and the bottom of the second clamp plate 301 of the embodiment are provided with clamping pads 302, and arc grooves are formed on the surfaces of the clamping pads 302; wherein the clamping pads 302 are directly in contact with the product, and some cylindrical products are fitted into the arc grooves, thereby increasing the contact area between the clamping pads 302 and the surface of the product, and the clamping is more firm, and the product will not easily slip during spot welding.

[0031] As shown in the drawings, Figure 3 As shown, the bottom of the support frame 2 is provided with a bottom plate, the bottom of the bottom plate is provided with a base 207, the length of the base 207 is less than the length of the bottom plate, and the bottom of the bottom plate is fitted to the top of the slide 101; wherein a threaded hole is formed in the center of the base 207, and the horizontal adjusting screw 102 is threadedly engaged with the threaded hole of the base when rotating, thereby driving the base 207 to move in the slide 101, so as to drive the support frame 2 to move, thereby adjusting the longitudinal position of the product, and the entire horizontal adjustment stroke is established by the movement of the base 207 in the slide 101. Since the base 207 has a smaller size, and the bottom plate is located on the top of the slide 101, the bottom plate can move beyond the edge of the slide 101 when moving, so that the stroke of the support frame 2 is longer, and the adjustment range is also larger.

[0032] As shown in the drawings, Figure 4 As shown, the two sides of the first clamp plate 3 of the embodiment extend into the interior of the support frame 2; wherein the region extending into the interior of the support frame 2 is controlled and adjusted by the height adjusting screw 202 provided with a threaded hole, and the extending part is supported by fitting the inner wall of the support frame 2, and is matched with the two height adjusting screws 202 rotating synchronously, thereby assisting the first clamp plate 3 to prevent tilting when moving up and down.

[0033] As shown in the drawings, Figure 2 As shown, the driven wheel 203 must be horizontally installed at a position corresponding to the driving wheel 204; wherein the two driving wheels 204 are vertically coaxially sleeved on the handle 206, and the corresponding driven wheel 203 and the driving wheel 204 need to be horizontal to ensure that the rotating chain 205 is not tilted, otherwise the transmission ratio of the two will deviate, causing the rotating speeds of the two height adjusting screws 202 to be inconsistent, and the first clamp plate 3 will be clamped in the support frame 2 or tilted.

[0034] Working principle: the product is put into the clamp plate 3 and the clamp plate 2 301 support, the clamping screw 303 is rotated to lower the clamp plate 2 301, and the two clamps are clamped on the product through the clamping gasket 302; the horizontal adjusting screw 102 is rotated to move the base 207 in the slide 101 to adjust the longitudinal position of the product; then the handle 206 is rotated to drive the two driving wheels 204 to rotate, the two driving wheels 204 drive a left and a right driven wheel 203 respectively through the chain 205, the driven wheel 203 is sleeved on the height adjusting screw 202, and the two supporting frames 2 in the height adjusting screw 202 are simultaneously rotated; the height adjusting screw 202 is engaged with the threaded holes at the two ends of the clamp plate 3, the clamp plate 3 drives the clamp plate 2 301 and the clamped product to move upward or downward to adjust the horizontal height position of the product; the products on the left and right sides can be adjusted separately to find the best welding position.

[0035] The utility model is not limited to the above-mentioned embodiment, any person should know the structural change made under the inspiration of the utility model, any technical scheme with the same or similar utility model falls into the protection scope of the utility model. The utility model does not describe the technology, shape and structure part in detail, which is the known technology.
