[0039] like Figure 2 and Fig. 9 As shown, the motor 201 is also included. The motor 201 is fixedly installed in the middle of the bottom of the carrier frame 102. The output shaft at the top of the motor 201 is fixedly connected to the rotating guide frame 202. The rotating guide frame 202 has at least four guide grooves 2021. The guide grooves 2021 are divided into an inclined propulsion area and an arc-shaped flat area. The inclined propulsion area is used to push the first sliding frame 103 to move, and the arc-shaped flat area is used to lock the first sliding frame 103. The guide grooves 2021 and the second sliding frame 103 are connected. The lower part of the movable frame 104 is slidably connected, and the side wall of the outer circle of the rotating guide frame 202 is fixedly connected with the missing gears 203 distributed circumferentially at equal intervals along the rotating guide frame 202. The supporting frame 102 is rotatably connected with the rotating shaft 204 distributed circumferentially at equal intervals along the supporting frame 102. Full gears 205 are fixed on the upper and lower sides of the rotating shaft 204. The full gear 205 on the upper side of the rotating shaft 204 is meshed with the rack frame 110, and the full gear 205 on the lower side of the rotating shaft 204 is meshed with the missing gear 203.

[0040] like Figure 2 , Fig.10 and Fig.11 As shown, it also includes a connecting block 301, which is fixedly connected to the middle of the second sliding frame 104. A magnet 302 is fixedly connected to one side of the connecting block 301 close to the lifting frame 107. The magnet 302 cooperates with the angle measuring rod 108 by magnetic attraction to reset the angle measuring rod 108.

[0041] like Figure 1 and Figure 2 As shown, an observation plate 601 is also included. The observation plate 601 is fixedly connected to the upper part of the side wall of the support frame 102. The support frame 102 is made of transparent material and is used to observe the scale of the scale.

[0042] First, the cylinder barrel of the gas cylinder is inverted in the middle of the top of the carrier 102, so that the measuring hole of the cylinder barrel covers the first sliding frame 103, and the placement is completed;

[0043] Then the motor 201 is started, the motor 201 drives the rotating guide frame 202, the missing gear 203 and the guide groove 2021 to rotate counterclockwise, the guide groove 2021 drives the second sliding frame 104 to move outward through the inclined propulsion area, the second sliding frame 104 thereby pulls the spring 105 to move outward, the spring 105 then drives the first sliding frame 103, the first scale 1031, the second scale 106, the lifting frame 107, the angle measuring rod 108, the slider 109, the connecting block 3 01 and the corresponding parts of the magnet 302 move outwards. In the process of the first sliding frame 103 moving outwards, the sharp part of the groove of the first sliding frame 103 touches the hole wall of the measuring hole and is blocked by the hole wall. The first scale 1031, the first sliding frame 103, the second scale 106, the lifting frame 107, the angle measuring rod 108 and the slider 109 stop moving. The hole wall is used as the measurement reference of the hole position. The hole wall position of the measuring hole can be known by observing the zero position of the first scale 1031.

[0044] When the first sliding frame 103 stops moving, the second sliding frame 104 is driven by the guide groove 2021 to continue to move outward, and the second sliding frame 104 drives the connecting block 301 and the magnet 302 to continue to move outward, so that the magnet 302 is out of the magnetic attraction range of the angle measuring rod 108, and the angle measuring rod 108 is unlocked. The spring 105 is deformed and stretched by the force. After the first sliding frame 103 is pulled by the spring 105, the measuring hole is tightened to prevent the cylinder from shaking during subsequent detection. Then, in the process of the second sliding frame 104 moving outward, the lifting frame 107 and the angle measuring rod 108 are driven by the inclined groove 1041 on the side wall. The measuring rod 108 moves upward to measure the hole depth of the measuring hole. If the hole depth of the measuring hole is tilted, it means that the side wall position of the measuring hole depth and the position of the cylinder opening are displaced. At this time, when the angle measuring rod 108 moves upward through the hole wall, the angle measuring rod 108 that detects the tilted position will be guided by the tilt angle of the hole wall to move inward, and the angle measuring rod 108 thereby drives the slider 109 to move inward. As the angle measuring rod 108 moves inward, the relative position of the angle measuring rod 108 and the second scale 106 changes, and the tilt of the measuring hole depth position is known by observing the second scale 106.

[0045] As the rotating guide frame 202 continues to rotate, after the second sliding frame 104 moves from the inclined propulsion area of ​​the guide groove 2021 to the arc-shaped flat area, the second sliding frame 104 stops moving outward. When the second sliding frame 104 slides into the arc-shaped flat area of ​​the guide groove 2021, the rotating guide frame 202 just drives the missing gear 203 to mesh with the full gear 205, thereby driving the full gear 205 and the rotating shaft 204 to rotate clockwise, and then drives the rack frame 110, the telescopic rod 111 and the limit measuring rod 112 to move inward. The corner protrusion of the limit measuring rod 112 near the top of the first scale 1031 moves relative to the first scale 1031. When the limit measuring rod 112 approaches inward, the limit measuring rod 112 The measuring rod 112 stops moving when it contacts the side wall outside the cylinder, while the rack frame 110 is still moving inward under force, and the telescopic rod 111 is adaptively compressed under force. When the tail end of the arc-shaped flat area of ​​the guide groove 2021 contacts the second sliding frame 104, the motor 201 stops rotating, and the zero position of the first scale 1031 and the scale position of the protruding part of the limit measuring rod 112 are observed through the observation plate 601 to obtain the thickness of the cylinder hole wall and the cylinder outer wall. Finally, the distance between the four first scales 1031 and the limit measuring rod 112 in the circumferential direction is observed, and the distance data of the four first scales 1031 are compared. According to the deviation between each first scale 1031, it is obtained whether the position of the measuring hole is offset.

[0046] After the detection is completed, the motor 201 is started to reverse, and the motor 201 drives the rotating guide frame 202 and the missing gear 203 to rotate clockwise and reset, thereby driving the full gear 205 and the rotating shaft 204 to rotate counterclockwise, and then driving the limit measuring rod 112 to move outward and reset. During the reset process, the guide groove 2021 pushes the second sliding frame 104 to reset inward, and then the spring 105 gradually resets, and the first sliding frame 103 no longer presses the limit hole. During the movement of the second sliding frame 104 inward, it drives the connecting block 301 and the magnet 302 to move inward, and the lifting frame 107 is guided by the inclined groove 1041, driving the angle measuring rod 108 to gradually move downward and reset, and then the magnet 302 gradually contacts the angle measuring rod 1 08 is close, when the angle measuring rod 108 enters the magnetic attraction distance of the magnet 302, it is affected by the magnetic force and moves outward quickly to complete the reset. Then, the cylinder after the test can be removed. In summary, the second sliding frame 104 cooperates with the first sliding frame 103 to achieve rapid measurement of the cylinder, which greatly improves the measurement efficiency. The second sliding frame 104 is used to measure with the hole wall as the reference and the outer wall of the cylinder as the reference, which greatly improves the flexibility of detection. It is not affected by the cylinder shape and can detect cylinders with different shapes. The hole wall measurement method reduces the influence of external factors such as machining error and deformation of the outer diameter of the cylinder on the measurement result, making the measurement result more reliable. The second sliding frame 104 moves to push the angle measuring rod 108 upward, so as to detect the hole depth position of the measuring hole, so as to know whether the depth position of the measuring hole deviates from the outer wall of the cylinder, and realize the multi-dimensional measurement of the cylinder hole position.

[0048] In order to prevent the cylinder from tipping over during the inspection process, the specific operation is as follows: when the cylinder is placed on the carrier 102 and the preparation work is completed, the limit plate 407 is then pressed, and the limit plate 407 pushes the piston rod of the piston cylinder 402 to adaptively contract, and the air in the piston cylinder 402 is squeezed and discharged from the lower air outlet 408. When the limit plate 407 fits with the bottom of the cylinder, the limit plate 407 is stopped from being pressed, and as the rotating guide frame 202 rotates counterclockwise, the first guide block 405 is driven to rotate, and when the first guide block 405 rotates, the second guide block 406 is squeezed to move downward, thereby bringing The movable lifting plate 403 descends to block the air outlet 408, and the spring piece 404 is compressed to lock the extended height of the piston barrel 402 to prevent the cylinder from tipping over. After the inspection of the cylinder bore is completed, the rotating guide frame 202 rotates counterclockwise to reset, thereby driving the first guide block 405 and the second guide block 406 to disengage, and the spring piece 404 is reset, thereby driving the lifting plate 403 to reset upward to release the blockage of the air outlet 408. In summary, through the cooperation of the lifting plate 403 and the piston barrel 402, automatic protection of the cylinder is achieved to prevent tipping over during the cylinder inspection process, thereby affecting the test accuracy.
