[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0022] Example:

[0023] See also Figure 1-Figure 3 , the utility model provides a technical solution:

[0024] A hydraulic cylinder detection device includes a test bench body 1, a support rod 2 is arranged on the outer side of the test bench body 1, and a support plate 3 is arranged at one end of the support rod 2 away from the test bench body 1, and further includes:

[0025] Limiting components 4, two sets of limiting components 4 are both located on the top of the test bench body 1, and the limiting components 4 are used to limit and clamp the hydraulic cylinder;

[0026] Furthermore, the limit assembly 4 is composed of a connecting shell 6, a moving block 7, a driving screw 8, a rotating rod 9, a limit block 10, a rotating block 11 and a fitting block 12. The connecting shell 6 is located at the top of the test bench body 1, the moving block 7 is slidably connected to the inside of the connecting shell 6, the driving screw 8 is located inside the moving block 7, two groups of rotating rods 9 are respectively rotatably connected to the two sides of the moving block 7, the limit block 10 is rotatably connected to the end of the rotating rod 9 away from the moving block 7, the rotating block 11 is rotatably connected to the outside of the limit block 10, and the two groups of fitting blocks 12 are both rotatably connected to the inside of the rotating block 11. When the hydraulic cylinder is tested, it can be limited and clamped by the limit assembly 4 to prevent the hydraulic cylinder from being offset during testing, thereby affecting the test effect.

[0027] Among them, the moving block 7 is internally rotatably connected with a threaded barrel, and a threaded groove is opened inside the threaded barrel. The internal structure size of the threaded barrel is designed to correspond to the external structure size of the driving screw 8. The threaded barrel is connected to the driving screw 8 through the threaded groove, and the driving screw 8 is rotatably connected to the connecting shell 6. The threaded groove is used for threaded connection of the driving screw 8, so that the threaded barrel can be threadedly connected to the driving screw 8, so that the moving block 7 can be connected to the driving screw 8. When the hydraulic cylinder needs to be tested, the hydraulic cylinder is placed between the two sets of limit blocks 10, and the driving screw 8 is rotated to drive the threaded barrel to move, so that the moving block 7 is displaced, and the rotating rod 9 is driven to rotate, so that the limit block 10 can be displaced and contact the hydraulic cylinder. When the limit block 10 contacts the hydraulic cylinder, the rotating block 11 and the fitting block 12 are subjected to relative force to rotate, so that they can fit the surface of the hydraulic cylinder, limit the hydraulic cylinder and clamp it to prevent the hydraulic cylinder from offset during testing.

[0028] Secondly, a plurality of rubber buffer strips are provided at one end of the bonding block 12 away from the rotating block 11, and the plurality of rubber buffer strips are evenly spaced on the surface of the bonding block 12. When the bonding block 12 contacts the hydraulic cylinder, the plurality of rubber buffer strips on its surface can increase the buffer distance between the bonding block 12 and the hydraulic cylinder, thereby preventing the bonding block 12 from damaging the surface of the hydraulic cylinder.

[0029] Furthermore, one end of the limit block 10 close to the connecting shell 6 is rotatably connected to the limit rod 13, and the end of the limit rod 13 away from the limit block 10 is rotatably connected to the connecting shell 6. The limit rod 13 is rotatably connected to the connecting shell 6, so that the limit block 10 can rotate with the connecting shell 6 through the limit rod 13. When the limit block 10 is displaced, the limit rod 13 can increase the stability of its displacement to prevent deviation.

[0030] The detection component 5 is located at one end of the support plate 3 close to the test bench body 1, and the detection component 5 is used to detect the hydraulic cylinder.

[0031] Furthermore, the detection component 5 is composed of a telescopic cylinder 14, a moving rod 15 and a detection head 16. The telescopic cylinder 14 is located at the top of the support plate 3, the moving rod 15 is located at one end of the support plate 3 close to the test bench body 1, and the detection head 16 is located at the end of the moving rod 15 away from the support plate 3. When the hydraulic cylinder is tested, it can be tested through the detection component 5.

[0032] Furthermore, the moving rod 15 is slidably connected to the support plate 3, and the driving end of the telescopic cylinder 14 passes through the support plate 3 and is fixedly connected to the moving rod 15. When the hydraulic cylinder is tested, the telescopic cylinder 14 is started to drive the moving rod 15 to move, so that the detection head 16 can move and contact the hydraulic cylinder, and the hydraulic cylinder can be tested through the detection head 16.

[0033] In this embodiment, the implementation scenario is specifically as follows: in actual use, when the hydraulic cylinder needs to be tested, the hydraulic cylinder is placed between two sets of limit blocks 10, and the drive screw 8 is rotated to drive the threaded barrel to move, so that the moving block 7 is moved, and the rotating rod 9 is driven to rotate, so that the limit block 10 can be displaced and contact the hydraulic cylinder. When the limit block 10 contacts the hydraulic cylinder, the rotating block 11 and the fitting block 12 are rotated by relative force, so that they can fit the surface of the hydraulic cylinder, and the hydraulic cylinder is limited and clamped to prevent the hydraulic cylinder from offset during testing. The telescopic cylinder 14 is started to drive the moving rod 15 to move, so that the detection head 16 can be displaced and contact the hydraulic cylinder. The detection head 16 enables the hydraulic cylinder to be tested. Compared with the existing detection device, the utility model can improve the overall practicality of the detection device through design.
