[0017] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0018] like Figure 1-3As shown, a detection tool for a swing cylinder comprises a positioning seat 1, a swing arm 2 and a driving cylinder 3, one end of the swing arm 2 is hinged on the positioning seat 1, and the other end of the swing arm 2 is hinged to the piston rod of the swing cylinder 4, one end of the swing cylinder 4 is hinged on the positioning seat 1, the driving cylinder 3 is hinged on the positioning seat 1, and the piston rod of the driving cylinder 3 is hinged to the swing arm 2, the swing cylinder 4 is tiltedly arranged on the positioning seat 1, and one end of the swing cylinder 4 is hinged on the positioning seat 1. When the driving cylinder 3 starts to work, its piston rod continuously performs telescopic movement, driving the swing arm 2 to swing back and forth, and the movement of the swing arm 2 drives the piston rod of the swing cylinder 4 to perform telescopic movement and swing, that is, the swing cylinder 4 rotates up and down relative to the positioning seat 1, thereby realizing the detection of the swing cylinder 4 in the swinging state, and through repeated and continuous movement, the continuous use time of the swing cylinder 4 and the number of telescopic times of the piston rod of the swing cylinder 4 can be judged, thereby realizing the service life detection of the swing cylinder 4.

[0019] Specifically, the positioning seat 1 includes a support leg 11 and a positioning plate 12 located on the support leg 11. The swing arm 2 and one end of the swing cylinder 4 are respectively hinged on the two ends of the positioning plate 12 along the length direction of the positioning plate 12. The driving cylinder 3 is arranged obliquely in the middle of the positioning plate 12 and is hinged to the positioning plate 12. The swing arm 2 and the swing cylinder 4 are both arranged obliquely on the positioning seat 1 and are obliquely connected to each other. When the swing arm 2 is rotated due to the piston rod of the driving cylinder 3, the angle between the swing arm 2 and the swing cylinder 4 will also change, which will also drive the swing cylinder 4 to swing up and down.

[0020] In order to adjust the inclination angle of the swing cylinder 4, a slide groove 121 arranged along the length direction is provided on one end of the positioning plate 12, and a movable slider 122 is provided in the slide groove 121. The end of the swing cylinder 4 away from the swing arm 2 is hinged to the slider 122. By moving the slider 122, the inclination of the swing cylinder 4 can be changed, so as to facilitate the detection of swing cylinders 4 with different inclinations and improve its detection range.

[0021] In order to drive the slider 122, a driving screw 123 is also included. A nut 122a is provided on one side of the slider 122. The driving screw 123 is arranged on one side of the slider 122 along the arrangement direction of the slide groove 121, and one end of the driving screw 123 can extend into the slider 122. The nut 122a is sleeved on the outside of the driving screw 123. When the driving screw 123 rotates, the nut 122a moves horizontally along the arrangement direction of the screw, driving the slider 122 to move in the slide groove 121.

[0022] In order to realize the installation and positioning of the swing cylinder 4, a through hole 124 is provided in the middle of the positioning plate 12, and hinged ear plates 125 are provided on the positioning plate 12 on both sides of the bottom of the through hole 124. The driving cylinder 3 is penetrated through the through hole 124, and the outer shells on both sides of the driving cylinder 3 are connected to the corresponding hinged ear plates 125 through a rotating shaft. The rotating shaft realizes the rotation installation of the driving cylinder 3 and the swing of the driving cylinder 3.
