[0036] Specifically, the fixture body 12 includes a mounting frame 121, a threaded rod 122, and a pressure plate 123. The threaded rod 122 is threadedly connected to the mounting frame 121, the pressure plate 123 is fixed to the bottom end of the threaded rod 122, and a handwheel is fixed to the top end of the threaded rod 122.

[0037] Rotating the handwheel on the fixture body 12 causes the threaded rod 122 to move downwards as it is threadedly connected to the mounting bracket 121. The pressure plate 123 at the bottom of the threaded rod 122 then descends until the pressure plate 123 presses the car parts firmly, thus fixing the car parts onto the mounting bracket 1.

[0038] The fan 141 is existing technology, and the working principle of this part is also existing technology, which can be clearly understood by those skilled in the art, and will not be described in detail here.

[0039] Example 2, refer to Figures 1 to 8This is the second embodiment of the present invention, which is based on the previous embodiment.

[0040] Specifically, a quincunx plate 125 is fixed to the bottom of one end of the mounting bracket 121. Both the quincunx plate 125 and the mounting bracket 121 have through holes, and the same bolt 124 passes through the through holes.

The bottom inner wall of the quincunx groove 13 has a threaded hole 11, and the bolt 124 is threadedly connected to the threaded hole 11.

[0041] By providing multiple slots 13 on the surface of the mounting bracket 1, various options are available for the placement of automotive parts and the installation of the fixture body 12. Adjust the mounting bracket 121 to a suitable angle, insert the slot 125 at the bottom of one end of the mounting bracket 121 into the slot 13 on the surface of the mounting bracket 1, then pass the bolt 124 through the through hole and screw it into the threaded hole 11 on the inner wall of the bottom of the slot 13, tighten the bolt 124, and firmly fix the fixture body 12 on the mounting bracket 1.

[0042] Specifically, a first stop rod 3 and a second stop rod 31 are fixed on one side of the hollow ball 22, a rod body 32 is fixed on one side of the knob 24, the angle between the first stop rod 3 and the second stop rod 31 is ninety degrees, and an indicator 33 is fixed on one side of the knob 24.

[0043] The rotation of knob 24 also drives the rotation of rod 32. Rotating knob 24 ninety degrees (causes rod 32 to rotate to the position of the first stop rod 3, where the first stop rod 3 blocks against the first stop rod 3; it should be noted that rotating knob 24 in the opposite direction will rotate rod 32 to the position of the second stop rod 31, thus switching back to the initial state).

[0044] Specifically, the hollow sphere 22 has a receiving cavity, and a sealing ring 41 is provided inside the receiving cavity. The sealing ring 41 is fitted onto the knob 24.

[0045] The sealing ring 41 can improve the sealing between the knob 24 and the hollow ball 22.

[0046] Specifically, a damping sleeve 4 is fitted on the outer side of one end of the knob 24, and one side of the damping sleeve 4 is fixedly connected to one side of the hollow ball 22.

[0047] The damping sleeve 4 increases the resistance of the knob 24, requiring an appropriate force to rotate it and preventing it from rotating freely. The inner diameter of the damping sleeve 4 is slightly smaller than the diameter of one end of the knob 24, thus generating resistance.

[0048] Specifically, a circular hole is provided between the receiving groove 16 and the cavity 17, and a one-way valve 18 is fixed on the inner wall of the circular hole.

[0049] The circular hole allows the receiving groove 16 and the cavity 17 to be connected, and the one-way valve 18 can prevent gas backflow and ensure that the smoke and dust can only flow in the set direction.

[0050] Specifically, a metal shaping hose 15 is fixed to one end of the second fixing tube 23.

[0051] The metal-shaped flexible hose 15 facilitates the extraction of smoke and dust, and its deformability allows for easy adjustment of its position.

[0052] Specifically, two sealing plates 142 are fixed to one side of the filter box 14 by screws, and the sealing plates 142 cover the receiving groove 16.

[0053] The receiving groove 16 can be sealed by the sealing plate 142, wherein a sealing gasket is fixed on the inner side of the sealing plate 142 to improve the sealing performance.

[0054] When in use, the entire unit is installed in a suitable working position (the support frame has mounting holes for easy installation). According to the shape and size of the automotive parts, a suitable position is selected on the placement frame 1, and the clamp body 12 is installed. By opening multiple plum blossom grooves 13 on the surface of the placement frame 1, a variety of options are provided for the placement of automotive parts and the installation of the clamp body 12.

[0055] The specific steps for installing the fixture body 12 are as follows: Adjust the mounting bracket 121 to a suitable angle, insert the plum blossom plate 125 at the bottom of one end of the mounting bracket 121 into the plum blossom groove 13 on the surface of the placement bracket 1, then pass the bolt 124 through the through hole and screw it into the threaded hole 11 on the inner wall of the bottom of the plum blossom groove 13, tighten the bolt 124, and firmly fix the fixture body 12 on the placement bracket 1. The number of fixture bodies 12 can be added or reduced according to actual needs.

[0056] Place the car parts on the placement rack 1, below the pressure plate 123. Turn the handwheel on the fixture body 12. Since the threaded rod 122 is threadedly connected to the mounting bracket 121, the handwheel drives the threaded rod 122 to move downward. The pressure plate 123 at the bottom of the threaded rod 122 then descends until the pressure plate 123 firmly presses the car parts, fixing the car parts on the placement rack 1 and preventing the car parts from moving during the welding process.

[0057] Adjust the metal shaping hose 15 by hand to align it with the welding position. During the welding process, start the fan 141. The fan 141 generates suction (one-way valve 18 opens). The fumes generated during the welding process are transported to the receiving tank 16 through the metal shaping hose 15 and filtered through the filter screen 161 (retaining particulate impurities in the fumes). The filtered gas is then drawn into the cavity 17 and discharged through the outlet of the fan 141, reducing the pollution of the working environment by the fumes during the welding process and protecting the health of the operators.

[0058] When the filter 161 needs to be replaced, the knob 24 can be rotated. The knob 24 drives the ball 25 to rotate inside the hollow ball 22. The rotation of the knob 24 also drives the rod 32 to rotate. Rotating the knob 24 ninety degrees (causing the rod 32 to rotate to the position of the first stop rod 3, where the first stop rod 3 blocks the first stop rod 3; it should be noted that rotating the knob 24 in the opposite direction will cause the rod 32 to rotate to the position of the second stop rod 31, thus switching back to the initial state). At this time, the direction of the conveying channel 251 inside the ball 25 is changed, and the two ends of the conveying channel 251 are aligned with the second fixed pipe 23 and another first fixed pipe 21, realizing the switching of the gas flow direction. The gas flow path can be flexibly controlled through the switching mechanism 2. Then, the gas is filtered through another unused filter 161. At this time, the used filter 161 can be removed and replaced (remove the screws of the sealing plate 142, pull the filter 161 out of the slot, replace it with a new filter 161, and then install the sealing plate 142 on the filter box 14).

[0059] The threaded rod 122 has a single-start thread (the thread helix angle is less than or equal to the equivalent friction angle, and it has self-locking properties). The material specifications of the threaded rod 122 can be selected according to actual needs. The material of the filter screen 161 is preferably activated carbon filter screen, but the specific material can be selected according to actual needs.

[0060] It should be noted that the fan 141 requires an external controller (such as a PLC controller) and an external power supply (such as mains power) for operation. When replacing the filter 161, workers may selectively wear protective equipment depending on the welding position.

[0061] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
