[0002] The hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swinging motion). During the production process of the hydraulic cylinder, it is necessary to detect the verticality of the piston rod in the cylinder. If the piston rod is not completely vertical, the hydraulic cylinder will generate a part of bending moment when pushing the piston rod during use. This will not only increase the energy consumption of the hydraulic cylinder, but also the bending moment will affect the service life of the piston rod under the action of long-term, resulting in the problem of piston rod breakage.

[0003] The existing piston rod verticality detection device usually inserts the piston rod into a fixed frame in a vertical direction, and the staff observes whether the piston rod is vertical. The fixed frame usually fixes piston rods of the same diameter. When piston rods of different diameters need to be detected, different fixed frames need to be replaced. The operation is relatively complicated, and the detection device is not easy to display the degree of bending of the piston rod. It is not convenient to adjust the piston rod production device and perform subsequent processing on the bent piston rod, resulting in low production efficiency of the piston rod.

[0004] Therefore, a verticality detection device that is easy to operate is needed to solve the problems in the prior art that the detection device is not easy to fix piston rods of different diameters and is not easy to display the degree of bending of the piston rod. Utility Model Content

[0023] The adjusting mechanism 8 includes a first motor 81 and a threaded rod 83. The first motor 81 is fixedly connected to the top surface of the base 1. The output end of the first motor 81 rotates through the inner wall of one side of the mounting frame 2 and is coaxially fixedly connected with a driving bevel gear 82. The bottom end of the threaded rod 83 is rotatably connected to the top surface of the base 1. The outer surface of the bottom of the threaded rod 83 is fastened with a driven bevel gear 84 meshing with the driving bevel gear 82. The threaded rod 83 is threadedly connected to the lifting rod 5.

[0025] Further Figure 1 As shown, it is worth explaining in detail that an arc block 10 is fixedly connected to the top surface of the base 1, and a plurality of scale lines 11 distributed in a circle are arranged on the outer wall of one end of the arc block 10.

[0026] Further Figure 1 and Figure 3 As shown, it is worth explaining in detail that an L-shaped rod 12 is fixedly connected to the top surface of the top plate 6, a second motor 13 is fixedly connected to an outer wall of one side of the transverse section of the L-shaped rod 12, and a driving gear 14 is coaxially fixedly connected to the output end of the second motor 13.

[0030] When the verticality of the piston rod is detected, according to the length of the piston rod to be detected, the first motor 81 is turned on to drive the active bevel gear 82 to rotate. Under the meshing action, the active bevel gear 82 drives the driven bevel gear 84 to rotate, thereby causing the threaded rod 83 to rotate on the top surface of the base 1. Through the cooperation of the slide groove 3 and the slider 4 and under the action of the thread, the lifting rod 5 rises in the mounting frame 2, thereby driving the top plate 6 to move upward, so as to adjust the height of the fixing component 9 and ensure that the bottom end of the piston rod fixed by the fixing component 9 is located above the arc block 10. By observing the position of the bottom end of the piston rod above the arc block 10, it is possible to determine whether the piston rod is vertical. The degree of bending of the piston rod can be understood through the scale line 11, which is convenient for subsequent adjustment of the piston rod and effectively avoids the problem that the detection device is not easy to display the degree of bending of the piston rod.
