[0002] The hydraulic cylinder is a device that can drive objects to perform reciprocating linear motion. The strength of the hydraulic cylinder is related to the stability and durability of the mechanical structure. Therefore, a strength testing device is required to test the hydraulic cylinder during its production and processing.

[0003] For example, the hydraulic cylinder performance test device disclosed in Chinese patent application number CN202222078504.8 has the following specific contents: the clamping assembly includes a clamping seat, a clamping plate, a screw and a clamping knob, wherein the clamping seat is fixedly connected to the inner side of one end of the test device body, the clamping plate is arranged directly above the clamping seat, the screw passes through the clamping plate and is fixedly connected to both sides of the clamping seat, the clamping knob is arranged above the clamping plate, and the clamping knob is threadedly connected to the screw. When fixing the hydraulic cylinder to be tested, the hydraulic cylinder is placed on the clamping seat, and then the clamping plate is slid down along the screw until it presses the hydraulic cylinder, and then the clamping knob is tightened to make it descend along the screw to squeeze the clamping plate, so that the clamping plate and the clamping seat clamp the hydraulic cylinder to achieve clamping and fixing of the hydraulic cylinder. The following technical problems exist:

[0004] The threaded connection between the clamping knob and the screw requires that two knobs be rotated when the hydraulic cylinder is clamped, which is cumbersome to operate and makes it difficult to quickly lock the hydraulic cylinder. Utility Model Content

[0032] The preferred specific implementation methods for implementing the present utility model are described in detail below, and a clear and complete description is made in conjunction with the accompanying drawings.

[0033] See also Figure 1-Figure 6 The utility model provides a hydraulic cylinder performance test bench.

[0034] The lower end of the clamping assembly 002 is provided with an operating table 001 for supporting and limiting the clamping assembly 002. The operating table 001 includes a supporting base plate 100. A supporting table 200 is fixedly installed on the upper left end of the supporting base plate 100. A limiting plate 220 is installed on the upper end of the supporting table 200. A telescopic rod 210 for limiting the limiting plate 220 is movably installed at the front and rear ends of the limiting plate 220. A pressure sensor 221 is fixedly installed at the middle of the right end of the limiting plate 220. A contact 222 is fixedly installed at the middle of the left end of the limiting plate 220. A counter 230 is installed at the middle of the supporting table 200. When testing the hydraulic cylinder, the hydraulic cylinder moves toward the limiting plate 220, contacts the pressure sensor 221, and pushes the limiting plate 220, so that the contact 222 and the counter 230 touch each other, thereby recording the number of extensions of the hydraulic cylinder.

[0035] An adjusting component 300 for limiting the clamping component 002 is movably installed at the upper end of the supporting base plate 100, a first limiting groove 310 for limiting the locking component 003 is provided in the middle of the adjusting component 300, a second limiting groove 311 is provided on one side of the first limiting groove 310, and a plurality of blocks 312 for cooperating with the locking component 003 to quickly lock the clamping component 002 are fixedly installed on the groove wall on one side of the second limiting groove 311. The long rod 600 slides in the groove cavities of the first limiting groove 310 and the second limiting groove 311. When the long rod 600 slides from the groove cavity of the first limiting groove 310 into the groove cavity of the second limiting groove 311, the clamping block 312 is clamped into the groove cavity of the clamping slot 620 to lock the long rod 600, so that the long rod 600 cannot move forward and backward, and the long rod 600 cannot move up and down, thereby limiting the clamping assembly 002, so that the clamping plate 500 and the clamping block 10 clamp and stabilize the hydraulic cylinder.

[0036] A reinforcing plate 320 is installed inside the adjusting assembly 300. A groove cavity for sliding the limit rod 510 is opened at the upper end of the adjusting assembly 300. The reinforcing plate 320 for limiting the limit plate 511 is installed at the lower end of the groove cavity. A screw nut 330 for cooperating with the reciprocating screw 400 to control the left and right movement of the adjusting assembly 300 is fixedly installed at the bottom of the adjusting assembly 300. When the reciprocating screw 400 is rotated by the turntable 410, the reciprocating screw 400 cooperates with the screw nut 330 to move the adjusting assembly 300, thereby adjusting the distance between the support platform 200 and the adjusting assembly 300 for hydraulic cylinders of different lengths. A fixed block for limiting the pin shaft 531 is installed inside the adjustment component 300, and a vertical groove for the pin shaft 531 to slide up and down is opened in the middle of the fixed block, so that when the long rod 600 presses the V-shaped rod 530 downward or pulls it upward, the distance between the clamping plate 500 and the clamping block 10 is closer to or farther away from each other.

[0037] A reciprocating screw 400 for adjusting the adjustment assembly 300 left and right is installed in the middle of the support base plate 100 , and a turntable 410 for rotating the reciprocating screw 400 is installed at the right end of the reciprocating screw 400 .

[0038] The clamping assembly 002 includes a clamping plate 500 for clamping the hydraulic cylinder, a non-slip pad 520 is fixedly installed in the middle of the clamping plate 500, a limit rod 1 510 is fixedly installed at the lower end of the clamping plate 500, a limit plate 511 for limiting the limit rod 1 510 is fixedly installed in the middle of the limit rod 1 510, and a limit rod 2 512 is fixedly installed at the lower end of the limit rod 1 510. The clamping plate 500 includes a clamping block 10 for cooperating with the clamping plate 500 to clamp the hydraulic cylinder, and the clamping block 10 and the clamping plate 500 have the same structure and size.

[0039] A V-shaped rod 530 is movably mounted on the lower end of the limiting rod 512, and a connecting block 532 for limiting the long rod 600 is fixedly mounted on the right end of the V-shaped rod 530, and a pin is mounted on the upper end of the connecting block 532, and the pin cooperates with the limiting hole 610 to limit the long rod 600, so that when the long rod 600 is pressed and pulled, the V-shaped rod 530 is synchronously driven to swing. A pin 531 is arranged in the middle of the V-shaped rod 530, and one end of the pin 531 is movably connected with a connecting rod 540 for cooperating with the V-shaped rod 530 to control the movement of the clamping block 10, and the upper end of the connecting rod 540 is movably mounted on the lower end of the clamping block 10. Through the arrangement of the V-shaped rod 530 and the connecting rod 540, when the long rod 600 is operated, the clamping plate 500 and the clamping block 10 are synchronously driven to move to clamp the hydraulic cylinder.

[0040] The lower end of the clamping assembly 002 is equipped with a locking assembly 003 for quickly locking the clamping assembly 002 in cooperation with the operating table 001. The locking assembly 003 includes a long rod 600, a slot 620 for engaging with the clamping block 312 is provided in the middle of the long rod 600, a limiting hole 610 is provided at the lower end of the long rod 600, and a handle 630 is installed at the upper end of the long rod 600 for facilitating the movement of the long rod 600. When clamping the hydraulic cylinder, the long rod 600 is pressed downward by holding the handle 630, so that one end of the V-shaped rod 530 moves downward synchronously, and drives the clamping plate 500 to rotate around the pin 531. The V-shaped rod 530 cooperates with the connecting rod 540 to make the clamping plate 500 and the clamping block 10 approach each other to clamp the hydraulic cylinder. After the hydraulic cylinder is clamped, the long rod 600 is moved from one end of the groove cavity of the first limiting groove 310 to the groove cavity mouth of the second limiting groove 311, and the long rod 600 is moved to the groove cavity of the second limiting groove 311, so that the blocking block 312 is inserted into the groove cavity of the blocking groove 620 to complete the rapid locking of the hydraulic cylinder.
