[0024] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Embodiment 1

[0026] See also Figure 1 - Figure 4 The utility model provides an automobile parts welding fixture, comprising: a base 1, a processing table 2 is fixedly installed on the top of the base 1, a groove is opened on the top of the processing table 2, two movable plates 3 are symmetrically slidably connected in the groove, and an adjustment mechanism for moving the movable plates 3 is provided in the groove;

[0027] The two movable plates 3 are provided with a flipping mechanism, the output end of the flipping mechanism is connected to a clamping block 14, and the two sides of the two movable plates 3 are symmetrically rotatably connected to two groups of supporting connecting rods 4, and the top end of each group of supporting connecting rods 4 is hinged to an L-shaped plate 5;

[0028] One side of the vertical section of the two L-shaped plates 5 is rotatably connected with a one-way screw rod 6, and a limiting guide rod 7 is fixedly installed on one side of the vertical section of the L-shaped plate 5 and located on both sides of the one-way screw rod 6, and a placement plate 8 that slides with the limiting guide rod 7 is threadedly connected to the surface of the one-way screw 6;

[0029] A driving member is provided on the L-shaped plate 5 , and a filtering mechanism is provided on the processing table 2 .

[0030] When in use, the two workpieces are placed on the two placement plates 8 respectively, and the one-way screw 6 is driven by the driving member to rotate, so that the placement plates 8 slide along the surface of the limiting guide rod 7, so that the two placement plates 8 move relatively close to each other, so as to make the butt surfaces of the two workpieces contact, and then the two movable plates 3 drive the flip mechanism and the clamping block 14 to move relatively close to each other through the adjustment mechanism, and the movable plate 3 drives the supporting connecting rod 4 to rotate, so that the L-shaped plate 5 moves up, and at the same time, the placement plate 8 drives the workpiece to rise. When the two workpieces are misaligned, the clamping block 14 first contacts one workpiece and pushes this workpiece to move until the clamping block 1 4 contacts two workpieces at the same time to achieve the clamping effect, which is convenient for personnel to weld. At this time, the placement plate 8 is located below the clamping block 14 and can support the workpiece. Therefore, the placement plate 8 and the clamping block 14 cooperate to achieve the effect of automatic deviation correction, clamping and fixing of the workpiece, avoiding the situation where the workpiece is misaligned and offset after clamping to affect the welding quality. No manual adjustment is required, which reduces the labor intensity of the personnel and effectively improves the convenience of use and the processing effect and efficiency. When the workpiece is turned over, the one-way screw 6 is driven by the driving member to rotate, so that the placement plate 8 is separated from the workpiece, and the workpiece is driven to turn over through the turning mechanism.

[0031] Furthermore, two gas springs 10 connected to the L-shaped plate 5 are symmetrically fixedly installed on the top of the processing table 2, and an anti-slip pad 15 is fixedly installed on one side of the clamping block 14.

[0032] Specifically, when the L-shaped plate 5 is raised or lowered, the gas spring 10 can be synchronously driven to extend and retract, so as to support the L-shaped plate 5 and ensure its rising stability. The anti-slip pad 15 is provided to increase the friction between the clamping block 14 and the workpiece, thereby ensuring the stability of the flipping.

[0033] Furthermore, the driving member is composed of a motor 9 fixedly mounted on the other side of the vertical section of the L-shaped plate 5. The output end of the motor 9 passes through the L-shaped plate 5 and is connected to the one-way screw 6. The thread grooves on the surfaces of the two one-way screws 6 rotate in opposite directions.

[0034] Specifically, when the workpiece is flipped, the one-way screws 6 at their output ends are driven by two motors 9 to rotate in the same direction. Since the thread grooves on the surfaces of the two one-way screws 6 rotate in opposite directions, the two placement plates 8 can be moved relative to each other and separated from the workpiece to prevent interference with the flipping of the workpiece.

[0035] Furthermore, the adjustment mechanism includes a bidirectional screw 11 rotatably connected between the two sides of the inner wall of the groove and a motor 12 fixedly installed on the outer circumferential surface of the processing table 2. The output end of the motor 12 penetrates into the groove and is connected to the bidirectional screw 11. The two movable plates 3 are threadedly connected to the surface of the bidirectional screw 11.

[0036] Specifically, when clamping the workpiece, the two-way screw 11 is driven to rotate by the second motor 12, thereby driving the two movable plates 3 to slide relatively close to each other along the groove, so that the clamping block 14 contacts the workpiece, thereby achieving the purpose of clamping and fixing the workpiece.

[0037] Furthermore, the flipping mechanism includes a rotating shaft rod 13 rotatably connected to the opposite surfaces of the two movable plates 3 and a motor 3 16 fixedly installed on one side of a movable plate 3, the output end of the motor 3 16 passes through the movable plate 3 and is connected to the rotating shaft rod 13, and the clamping block 14 is fixedly connected to one end of the rotating shaft rod 13.

[0038] Specifically, when the two movable plates 3 are relatively close to each other, the clamping block 14 can contact the two sides of the workpiece to achieve the effect of clamping and fixing. When the workpiece is turned over, the placing plate 8 and the workpiece are separated, and the motor 3 16 drives the rotating shaft rod 13 to rotate, thereby driving the workpiece to rotate and turn over through the clamping block 14.

[0041] The purification component is composed of a dust suction fan 20 fixedly installed on one side of the filter box 19, a dust suction cover 21 fixedly installed on the other side of the filter box 19, a filter screen 22 fixedly installed in the dust suction cover 21, two notches symmetrically opened on the top of the filter box 19, and a high-efficiency air filter screen 23 and an activated carbon filter screen 24 slidingly connected to the two notches from front to back in sequence.

[0042] The technical solution provided by this embodiment is as follows: a negative pressure is formed in the filter box 19 through the dust suction fan 20, and the exhaust gas generated by welding can be absorbed by the dust suction hood 21, and large particles of impurities are filtered through the filter 22, and then the exhaust gas enters the filter box 19, and small particles of impurities are filtered again through the high-efficiency air filter 23, and finally the exhaust gas is purified and discharged through the activated carbon filter 24, so as to achieve the effect of filtering and purifying the exhaust gas and dust, and prevent the exhaust gas and dust from affecting the health of personnel;

[0043] The moving block can be used to drive the rotating ring 17 to rotate, so as to adjust the position of the dust hood 21 and to facilitate the exhaust gas suction at different positions.

[0044] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
