[0025] Installation step: Dock the second guide rail on the sliding plate with the first guide rail on the fixed plate, and push the sliding plate to move in the direction approaching the fixed plate. When the sliding plate drives the male joint to be inserted into the female joint, positioning is achieved. Then drive the locking mechanism so that the output shaft of the locking mechanism extends and is inserted into the positioning pin hole on the sliding plate to achieve locking, and the installation is completed;

[0026] Disassembly steps: Drive the locking mechanism so that the output shaft of the locking mechanism shrinks and moves away from the positioning pin hole on the sliding plate. After the output shaft of the locking mechanism completely moves away from the positioning pin hole, pull the sliding plate to move in the direction away from the fixed plate. The sliding plate drives the male connector and the female connector to be completely separated. Continue to pull the sliding plate to move in the direction away from the fixed plate until the second guide rail is completely disengaged from the first guide rail, and the disassembly is completed;

[0027] Steps for replacing the fixture: Remove the fixture from the sliding plate, install another prepared fixture, and after replacement, install it according to the fixture installation steps.

[0028] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0029] 1. The fixture quick replacement device of the present invention includes a fixed plate, a sliding plate, a push-pull guide rail, and a quick-connect joint assembly; the sliding plate and the fixed plate are slidably matched through the push-pull guide rail. Driving the sliding plate to move in the direction approaching or away from the fixed plate can make the sliding plate drive the male connector and the female connector to be inserted or separated; driving the output shaft of the locking mechanism to extend or shrink can make the output shaft insert into or move away from the positioning pin hole on the sliding plate. Therefore, the present invention can effectively improve the replacement efficiency and positioning accuracy of the fixture. The fixture quick replacement method of the present invention includes: equipment preparation steps, installation steps, disassembly steps, and fixture replacement steps; this method has the characteristics of quick replacement, automatic positioning and locking of the fixture, accurate positioning, convenient operation, high work efficiency, low labor cost, and does not require the assistance of other tightening tools, with higher safety.

[0030] 2. The number of locking mechanisms of the present invention is two. Correspondingly, the number of positioning pin holes is two. When the number of locking mechanisms is one, during the processing, the sliding plate is prone to shaking, having the disadvantage of unstable positioning. When the number of locking mechanisms is more than three, there are disadvantages of large occupied space, high manufacturing and use costs. In addition, the two locking mechanisms of the present invention are respectively arranged at both ends of the same diagonal line of the fixed plate. Correspondingly, the positions of the two positioning pin holes are respectively corresponding to the two locking mechanisms. Such a design has the characteristic of stable positioning, which is not only beneficial to avoiding the shaking of the sliding plate during the processing, but also can reduce the occupied space of the locking mechanism. The staggered design is also beneficial to the layout of electrical signal lines and air pipes.

[0031] 3. The first guide rail of the present invention includes two L-shaped guide rails symmetrically arranged on the bottom surface of the fixed plate. A sliding channel is formed by enclosing between the two L-shaped guide rails and the bottom surface of the fixed plate. The L-shaped guide rail includes a longitudinal connecting portion fixedly connected to the bottom surface of the fixed plate and a transverse guiding portion. A notch for the fixture to pass through is formed between the two transverse guiding portions. The second guide rail includes two linear sliders symmetrically arranged on the two side surfaces of the sliding plate. The sliding plate is inserted into the sliding channel, so that the two linear sliders are respectively in sliding fit with the transverse guiding portions of the two L-shaped guide rails. This design has the advantages of simple structure and more stable sliding fit. Tapered surfaces are provided at one ends of the two transverse guiding portions adjacent to the sliding plate. This design enlarges the opening of the sliding channel, which is beneficial to the better insertion of the sliding plate into the sliding channel.

[0032] 4. A limiting plate is further provided at the open end of the sliding channel of the present invention away from the sliding plate. The top surface of the limiting plate is fixedly connected to the bottom surface of the fixed plate, and its two ends are respectively fixedly connected to the two transverse guiding portions. This design ensures that when the sliding plate moves in the sliding channel to a position in contact with the limiting plate, the male connector and the female connector are just fully inserted, and the positioning pin hole on the sliding plate just moves to directly below the output shaft of the locking mechanism. Therefore, in actual operation, only by pushing the sliding plate to the bottom of the sliding channel can the positioning be completed, which has the advantages of convenient operation and accurate positioning; at the same time, it can also increase the connection strength of the two L-shaped guide rails.

[0033] 5. The male connector mounting bracket of the present invention includes a mounting plate with an L-shaped cross-section. The mounting plate includes a vertical mounting plate and a horizontal mounting plate. The horizontal mounting plate is fixedly mounted on the sliding plate. A first strip-shaped hole for the power supply signal line and the air pipe to pass through is further provided on the horizontal mounting plate. A second strip-shaped hole for the power supply signal line and the air pipe to pass through is also provided on the sliding plate at a position corresponding to the first strip-shaped hole. An outer cover covering the first strip-shaped hole is further provided on the horizontal mounting plate. This design can prevent the power supply signal line and the air pipe from being exposed, which is both beautiful and safe.

[0034] 6. The female air pipe connector of the present invention is a self-sealing connector. This design ensures that there is no gas leakage when the fixture is withdrawn. A handle is also provided on the sliding plate. This design facilitates the operator to carry out disassembly and assembly work. BRIEF DESCRIPTION OF THE DRAWINGS

2. The fixture quick replacement device according to claim 1, characterized in that The locking mechanism is a cylinder or a servo motor.

3. The fixture quick change device according to claim 1, characterized in that, The female air pipe joint is a self-sealing joint; a handle is further provided on the sliding plate.

4. A method for quickly replacing a fixture, characterized in that, It includes the following steps: Equipment preparation step: Provide a fixture quick-change device as described in any one of claims 1-3. Installation step: Dock the second guide rail on the sliding plate with the first guide rail on the fixed plate, and push the sliding plate to move in the direction approaching the fixed plate. When the sliding plate drives the male connector to be inserted into the female connector, positioning is achieved; then drive the locking mechanism so that the output shaft of the locking mechanism extends and is inserted into the positioning pin hole on the sliding plate to achieve locking, and the installation is completed. Dismantling step: Drive the locking mechanism so that the output shaft of the locking mechanism contracts and leaves the positioning pin hole on the sliding plate. When the output shaft of the locking mechanism completely leaves the positioning pin hole, pull the sliding plate to move in the direction away from the fixed plate. The sliding plate drives the male connector and the female connector to be completely separated, and continue to pull the sliding plate to move in the direction away from the fixed plate until the second guide rail is completely separated from the first guide rail, and the dismantling is completed. Fixture replacement step: Dismantle the fixture from the sliding plate, install another prepared fixture, and after replacement, perform the installation according to the fixture installation steps.
