A jig for detecting the vacuum adsorption force of a template comprises a detection jig 1 and a template body 5, the template body 5 is connected to the outer wall of the detection jig 1, a vacuum cavity 101 is cut out on the outer wall of the detection jig 1, a vacuum tube 2 is connected to the outer wall of the vacuum cavity 101, a vacuum adsorption air pipe interface 201 is connected to the outer wall of the vacuum tube 2, a vacuum pressure detector 3 is connected to the end of the vacuum tube 2 away from the detection jig 1, a compressed air pipe 4 is also connected to the outer wall of the vacuum pressure detector 3, grooves 102 are cut out on the outer walls of both sides of the detection jig 1, a second elastic element 9 is connected to the inner wall of the groove 102, a push plate 10 is connected to the end of the second elastic element 9 away from the inner wall of the groove 102, and the inner wall of the groove 102 is also connected to the sliding plate 10. A plug rod 6 is movably connected, and the plug rod 6 and the push plate 10 are movably opposed to each other. The outer wall of the plug rod 6 is chiseled with evenly distributed positioning grooves 601, and the inner wall of the positioning groove 601 is slidably connected with a positioning rod 602. A first elastic element 603 is connected between the positioning rod 602 and the inner wall of the positioning groove 601. The outer walls of the detection fixture 1 and the template body 5 are respectively chiseled with a first concave hole 7 and a second concave hole 8 that match the positioning rod 602. The aperture of the first concave hole 7 is larger than the aperture of the second concave hole 8. The top of the positioning rod 602 is provided with an inclined surface, which is movably opposed to the detection fixture 1 and the template body 5 respectively. A card groove 6021 is chiseled on the outer wall of the positioning rod 602, and the inner wall of the card groove 6021 is movably opposed to the template body 5.

[0028] Insert the insertion rod 6 into the groove 102, and make the insertion rod 6 slide into the groove 102. During the sliding process, the detection fixture 1 and the template body 5 squeeze the inclined surface of the positioning rod 602, so that the first elastic element 603 contracts, and the positioning rod 602 retracts into the positioning groove 601. As the insertion rod 6 is pushed to the right, the insertion rod 6 squeezes the push plate 10 and compresses the second elastic element 9, which no longer exerts force on the insertion rod 6. The second elastic element 9 recovers and pushes the insertion rod 6 to move left. After moving a certain distance, the top of the positioning rod 602 is not squeezed. Figure 4 As shown, the first elastic element 603 will push the positioning rod 602 to slide in the positioning groove 601, and make the positioning rod 602 pass through the first recessed hole 7 and the second recessed hole 8. At the same time, the second elastic element 9 will continue to push the insertion rod 6 to move left. The first recessed hole 7 is larger than the second recessed hole 8. The insertion rod 6 drives the positioning rod 602 to move in the first recessed hole 7, and makes the inner wall of the slot 6021 gradually abut against the top of the template body 5. At this time, the positioning rod 602 is stuck by the template body 5, and the positioning rod 602 drives the insertion rod 6 to no longer move left with the push of the second elastic element 9, thereby realizing the fixation of the detection fixture 1 and the template body 5. The present invention provides a fixture for detecting the vacuum adsorption force of the template, which realizes locking and fixing of the detection fixture 1 and the template through the positioning rod 602 on the outside of the insertion rod 6, replacing the screw fixing method, and simply and quickly completing the installation and disassembly of the template, saving operation time and improving work efficiency.

[0029] Embodiment 1:

[0030] Please refer to Figure 3-5 ,in, Figure 3 A schematic diagram of the structure of a detection jig and a template body in a jig for detecting the vacuum adsorption force of a template provided by the present invention, Figure 4 A schematic diagram of the cross-sectional structure of a detection jig in a jig for detecting the vacuum adsorption force of a template provided by the present invention, Figure 5 A fixture for detecting the vacuum adsorption force of a template provided by the present invention Figure 4 A through hole is drilled in the detection fixture 1, and a main pull rope 11 is movably connected in the through hole. A branch pull rope 111 is connected to the outer wall of the main pull rope 11. The branch pull rope 111 is connected to the bottom of the positioning rod 602. The outer wall of the main pull rope 11 is also connected to a pull ring 112, and the pull ring 112 is placed outside the insertion rod 6; when it is necessary to separate the detection fixture 1 from the template body 5, the insertion rod 6 is pushed to the right to squeeze the second elastic element 9, and the second elastic element 9 contracts, so that the positioning rod 602 moves to Figure 4 The picture shown, that is, the outer wall of the template body 5 no longer abuts against the inner wall of the slot 6021, and then the pull ring 112 is pulled, so that the pull ring 112 drives the main pull rope 11 to move left in the through hole, so that the main pull rope 11 drives the sub-pull rope 111 to pull the positioning rod 602 to retract into the positioning slot 601, and the first elastic element 603 is compressed, so that the positioning rod 602 is retracted from the first recessed hole 7 and the second recessed hole 8. At this time, the positioning rod 602 has completely entered the positioning slot 601 and is no longer in contact with the template body 5 or the detection fixture 1, so that the detection fixture 1 is separated from the template body 5, and the insertion rod 6 can also be moved to the left to pull out of the groove 102.

[0031] The outer wall of the template body 5 is connected with a positioning block 501 , and the outer wall of the detection fixture 1 is drilled with a positioning hole 12 that matches the positioning block 501 , so as to facilitate the positioning between the detection fixture 1 and the template body 5 .

[0032] One end of the insertion rod 6 placed inside the groove 102 is set to be trapezoidal, which facilitates the insertion rod 6 to enter the groove 102.

[0033] A handle 13 is provided on the outer wall of the insertion rod 6 to facilitate pushing the insertion rod 6 .

[0034] The working principle of a fixture for detecting the vacuum adsorption force of a template provided by the present invention is as follows:

[0035] Insert the insertion rod 6 into the groove 102, and make the insertion rod 6 slide into the groove 102. During the sliding process, the detection fixture 1 and the template body 5 squeeze the inclined surface of the positioning rod 602, so that the first elastic element 603 contracts, and the positioning rod 602 retracts into the positioning groove 601. As the insertion rod 6 is pushed to the right, the insertion rod 6 squeezes the push plate 10 and compresses the second elastic element 9, which no longer exerts force on the insertion rod 6. The second elastic element 9 recovers and pushes the insertion rod 6 to move left. After moving a certain distance, the top of the positioning rod 602 is not squeezed. Figure 4 As shown, the first elastic element 603 will push the positioning rod 602 to slide in the positioning groove 601, and make the positioning rod 602 pass through the first recessed hole 7 and the second recessed hole 8. At the same time, the second elastic element 9 will continue to push the insertion rod 6 to move left. The first recessed hole 7 is larger than the second recessed hole 8. The insertion rod 6 drives the positioning rod 602 to move in the first recessed hole 7, and makes the inner wall of the slot 6021 gradually contact with the top of the template body 5. At this time, the positioning rod 602 is stuck by the template body 5, and the positioning rod 602 drives the insertion rod 6 to no longer move left with the push of the second elastic element 9, thereby achieving the fixation of the detection fixture 1 and the template body 5.
