With the improvement of people's living standards, people's consumption of cars is also increasing, and car headlights are an important part of auto parts. In the process of adjusting the headlights, an adjusting screw is required, and in the process of producing the adjusting screw, it needs to be assembled and welded. Therefore, a car headlight adjusting screw assembly and welding device is particularly needed.

[0003] However, in the existing automobile headlight adjusting screw assembly welding device, during use, most welding equipment can only perform single-sided welding work on the adjusting screw, which is not convenient for rotating welding of the adjusting screw, greatly reducing the assembly welding efficiency of the automobile headlight adjusting screw.

[0004] Chinese patent CN217167092U discloses an assembly welding device for adjusting screws of automobile headlights. The device solves the problem that most welding equipment can only perform single-sided welding on the adjusting screws, which is inconvenient for rotational welding of the adjusting screws, greatly reducing the assembly welding efficiency of the adjusting screws of automobile headlights; however, in actual operation, the lengths of the screws and the bolt heads are often inconsistent, the welding equipment in the device only has up and down adjustment, and the clamping mechanism and the support seat in the device cannot realize the adjustment function, which makes it difficult to weld accurately during the welding process, resulting in a low product qualification rate and greatly reducing the processing efficiency. Summary of the invention

The bolt rod and the bolt head are clamped respectively by a first clamping mechanism and a second clamping mechanism, and the height of the welding gun is adjusted by a welding gun moving device. When the welding gun is working, the first rotating mechanism and the second rotating mechanism rotate synchronously, so that the welding gun can weld at multiple angles. At the same time, when welding bolts of different sizes, the first clamping device and the second clamping device are driven to shrink and move respectively by the first multi-link contraction mechanism and the second multi-link contraction mechanism, so that bolts of different sizes can be processed. After the processing is completed, the processed bolts are transported to a material collection area by a horizontal moving device. At this time, the clamping device is released to allow the processed bolts to enter the material collection area, thereby increasing practicality.

The first vertical moving mechanism 41 and the second vertical moving mechanism 42 have the same structure. The first vertical moving mechanism 41 and the second vertical moving mechanism 42 are fixedly arranged on the first horizontal moving mechanism 31 and the second horizontal moving mechanism 32 respectively.

[0123] The multi-link contraction device 5 includes a first multi-link contraction mechanism 51 and a second multi-link contraction mechanism 52.

The first rotating mechanism 81 is arranged at the output end of the first multi-link contraction mechanism 51, and the second rotating mechanism 82 is arranged at the output end of the second multi-link contraction mechanism 52.

[0125] The clamping device 6 includes a first clamping mechanism 61 and a second clamping mechanism 62. The first clamping mechanism 61 and the second clamping mechanism 62 have the same structure.

[0126] The material collecting mechanism 7 is arranged in the cavity, and a baffle 71 is arranged inside the material collecting mechanism 7 . The baffle 71 divides the material collecting mechanism 7 into a material collecting area 711 and a welding slag collecting area 712 .

[0127] When it is necessary to weld bolts, the bolt rod and the bolt head are clamped respectively by the first clamping mechanism 61 and the second clamping mechanism 62, and the height of the welding gun 25 is adjusted by the welding gun moving device 2. When the welding gun 25 is working, the first rotating mechanism 81 and the second rotating mechanism 82 rotate synchronously, so that the welding gun 25 can weld at multiple angles. At the same time, when welding bolts of different sizes, the first multi-link contraction mechanism 51 and the second multi-link contraction mechanism 52 respectively drive the first clamping device 6 and the second clamping device 6 to contract and move, so that bolts of different sizes can be processed. After the processing is completed, the processed bolts are transported to the material collection area 711 by the horizontal moving device 3. At this time, the clamping device 6 is released to allow the processed bolts to enter the material collection box, thereby increasing practicality.

[0139] When bolts of different lengths need to be processed, the two-way screw 511 is rotated to make the slider move toward or in the opposite direction, while driving the X-shaped bracket 514 to stretch and contract until it is adjusted to a position suitable for bolt processing. The above operations solve the problem of processing bolts of different lengths.

Through the arrangement of the slide plate 3161, a certain supporting force can be given to the support plate 316, thereby extending the service life of the second belt 315.

[0153] The welding gun 25 is disposed on a side of the second extension plate 241 away from the first bracket 21 .

[0154] The first motor 22 rotates to rotate the first screw rod 23 , and the first sliding bracket 24 can move up and down in coordination with the first screw rod 23 , thereby achieving the up and down adjustment of the welding gun 25 .

[0155] See also Fig.13 As shown, the first rotating mechanism 81 includes a dividing plate 811;

[0156] A pair of hinged seats are provided at one end of the indexing plate 811 close to the X-shaped bracket 514 , and the hinged seats are hinged to the X-shaped bracket 514 .

[0157] By setting the indexing plate 811, the first rotating mechanism 81 can drive the first clamping device 6 to rotate, thereby driving the bolt to be processed to rotate, so that multi-angle welding is possible during welding.

[0164] The limit sensor 4141 is fixedly disposed on a side of the second sliding bracket 414 away from the second screw rod 413 .

[0165] By using the limit sensor 4141, the multi-link retraction device 5, the rotating device 8 and the clamping device 6 are always kept in the same horizontal plane, so that the bolts to be processed are kept in the same horizontal plane, thereby achieving better processing effects and a higher qualified rate of processed products.

[0166] See also Fig.11 As shown, the material collecting mechanism 7 further includes a slide bar 72;

[0167] The slide bar 72 has a pair and is arranged in mirror image on both sides of the material collecting mechanism 7 .

[0168] The setting of the slide bar 72 makes it easier to save effort when the material collecting mechanism 7 is pulled out. The slide bar 72 also has the function of blocking welding slag, preventing the welding slag from entering the cavity, and increasing the resistance of the material collecting mechanism 7 when being pulled out.

[0169] When it is necessary to weld bolts, the head and tail of the bolts are clamped respectively by two three-jaw chucks 611, and the first slider 512 and the second slider 513 are moved toward or in the opposite direction by rotating the bidirectional screw 511, so that the X-shaped bracket 514 can contract, so that it can adapt to the position of bolts of different lengths to obtain a precise welding position. The rotating device 8 rotates so that the bolts can contact and weld with the welding gun 25 at multiple angles, so that the welding quality is more reliable. After the welding is completed, the processed bolts can be accurately transported to the material collection area 711 by adjusting the vertical moving device 4 and the horizontal moving device 3. At this time, the clamping device 6 is released to allow the processed bolts to enter the material collection area 711, thereby increasing practicality.

It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
