[0002] At present, most welding workshops adopt a production method of switching fixtures of different models on a four-sided turntable, that is, four different types of fixtures are fixed on the four sides of the turntable, and the fixtures of the corresponding models are rotated to the welding robot for processing by rotating the turntable, but this method can only meet the welding of 4 types of models. If more types of models are to be processed, the fixture needs to be removed from the turntable and replaced with a fixture of the new model. Due to the large size and heavy weight of the fixture, the disassembly and transportation process is time-consuming and labor-intensive, which seriously affects production efficiency. Therefore, the applicant has developed a method for quick replacement of fixtures, which connects the trolley with the turntable. After the fixture is disassembled, it is directly pushed horizontally onto the trolley and transported away by the trolley. The fixture that needs to be replaced is transported by the trolley and pushed directly onto the turntable to achieve quick replacement of the fixture. The applicant found in actual application that the stable movement of the fixture is the key to quick replacement of the fixture. How to ensure the stable movement of the fixture is a problem that needs to be solved urgently. Utility Model Content

Rollers are rotatably installed at the bottom of both sides of the fixture 2, and the rollers can roll on the top surfaces of the fixture rail 22 and the trolley rail 21, and anti-skew wheels 24 are rotatably installed on both sides of the rollers, and the anti-skew wheels 24 can roll on the sides of the fixture rail 22 and the trolley rail 21.
[0025] Combination Figure 3As shown, the clamp guiding mechanism also includes a pressure plate 11, and wing plates 26 are integrally formed on both sides of the clamp 2, and a pressure plate seat 27 is bolted on the wing plate 26. One end of the pressure plate 11 is placed on the pressure plate seat 27, and the other end of the pressure plate 11 is placed on the trolley 1. Limiting plates 25 for limiting the pressure plate 11 are vertically fixed on both sides of the top of the pressure plate seat 27 by bolts.
[0026] Combination Figure 5 As shown, the trolley guide mechanism includes wheel guide plates symmetrically arranged on the ground on both sides of the trolley 1, the wheel guide plates are used to guide the wheels 12 of the trolley 1, and the wheel guide plates include a straight section 14 extending along the moving direction of the trolley 1 (radial direction of the turntable 3) and an outer deflection section 13 offset toward the outside of both sides of the trolley 1, and the straight section 14 is smoothly connected to one end of the outer deflection section 13 close to the turntable 3 ( Figure 5 center left).
[0027] Combination Figure 6 As shown, the trolley guide mechanism also includes guide wheels and guide blocks 15. The guide wheels include side guide wheels 153 and top guide wheels 155. The guide blocks 15 are symmetrically fixed on the ground. Figure 6 The figure shows the guide block 15 on the right side of the trolley 1.

[0028] The working principle of a fixture quick-change guide structure is as follows:
[0029] The trolley 1 moves to the fixture 2 that needs to be switched, and the trolley 1 drives toward the turntable 3, so that the trolley slide rail 21 is docked with the fixture slide rail 22. During the docking process, on the one hand, the wheel guide plates on both sides guide the wheels 12 of the trolley 1; on the other hand, the side guide wheels 153 roll along the side guide surfaces of the guide blocks 15, and the top guide wheels 155 roll along the top surfaces of the guide blocks 15; on the other hand, the Z-shaped docking notch on the trolley slide rail 21 is inserted into the Z-shaped guide notch 23 on the fixture slide rail 22. The trolley 1 is guided from the above three aspects to ensure that the trolley slide rail 21 and the fixture slide rail 22 are accurately docked.
[0030] After the trolley rail 21 and the fixture rail 22 are docked, the trolley 1 is in place. After the trolley 1 is in place, the pressure plate 11 is placed, with one end of the pressure plate 11 pressing on the pressure plate seat 27, and the other end of the pressure plate 11 pressing on the trolley 1. The worker removes the bolts connecting the fixture 2 and the turntable 3, and then pushes the fixture 2 along the fixture rail 22 and the trolley rail 21 onto the trolley 1, and is transported away by the trolley 1. The fixture 2 that needs to be replaced is transported to the turntable 3 by the trolley 1. After the trolley rail 21 and the fixture rail 22 are docked, the fixture 2 that needs to be replaced is pushed onto the turntable 3 along the trolley rail 21 and the fixture rail 22, and the fixture 2 is fixed to the turntable 3 with bolts, and the replacement of the fixture 2 is completed.
[0031] When the clamp 2 slides along the trolley slide rail 21 and the clamp slide rail 22, the anti-deflection wheels 24 on both sides hold the trolley slide rail 21 and the clamp slide rail 22 to prevent deflection. On the other hand, the wing plates 26 on both sides of the clamp 2 move along the pressure plate 11 through the pressure plate seat 27, which can further guide the movement of the clamp 2 and improve the sliding stability of the clamp 2. In addition, the pressure plate 11 pressed on both sides of the clamp 2 can further prevent the clamp 2 from lateral deflection and improve the anti-deflection effect.
