In addition, the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
Referring to fig. 1 to 4, the present application provides a hydraulic cylinder testing apparatus for actually measuring various parameters of a hydraulic cylinder to determine whether the hydraulic cylinder meets an expected standard. This pneumatic cylinder test equipment includes: the device comprises a base 10, a loading oil cylinder 20, a first fixed seat 30, a second fixed seat 40 and a sensor 50.
The piston rod of the loading oil cylinder 20 is in collinear connection with the piston rod of the oil cylinder to be tested so as to apply load to the oil cylinder to be tested. The sensor 50 may be used to monitor the operating state of the cylinder under test when the load cylinder 20 applies a load to the cylinder under test. The first fixing base 30 is disposed on the base 10, and is used for mounting the loading cylinder 20. Referring to fig. 2 and 4, the second fixing base 40 is disposed on the base 10, and includes a fixing base 41 and a flange 42 detachably mounted on the fixing base 41; and the flange 42 is used for installing the oil cylinder K to be tested. Different flanges can be adapted to mounting hydraulic cylinders K of different sizes.
A first cylinder support base 60 is installed on the base 10, and is used to support the cylinder body of the loading cylinder 20. The second cylinder support 70 is mounted on the base 10 and is used for supporting the cylinder body of the cylinder to be measured. The first cylinder support 60 and the second cylinder support 70 can enhance the stability of the cylinder during the test.

The sleeve 80 connects the supports on the base 10 together, which can increase the stability of the whole device during the oil cylinder test.
Referring further to fig. 1, a plurality of rows of mounting holes 11 are disposed on the base 10, and each row of mounting holes 11 is arranged along the extending direction of the loading cylinder 20, so that the second fixing seat 40 and the second cylinder supporting seat 70 can be installed at different positions, thereby adapting to cylinders with different sizes.
Referring to fig. 3, the second cylinder support 70 includes a support base 71 and a plurality of jack posts 72; a supporting through hole 711 for the cylinder body of the oil cylinder to be tested to pass through is formed in the supporting base 71; the ejector pin groups 72 are uniformly arranged along the circumferential direction of the support through hole 711. The ejector rod assembly 72 is used for supporting the cylinder body of the oil cylinder to be measured at multiple points from multiple positions in the circumferential direction.
Further, the push rod assembly 72 includes a rod body 721 mounted on the support base 71, and a pressing block 722 disposed on the rod body 721; the pressing piece 722 is provided at one end of the rod body 721 extending into the support through hole 711. The rod body 721 can axially adjust the length of the rod body extending into the supporting through hole 711, so that the press block 722 is pressed against the surface of the cylinder body of the oil cylinder to be tested. During installation, the oil cylinder to be tested firstly penetrates through the supporting through hole 711, and then the position of each rod body 721 is adjusted to change the length of the rod body stretching into the supporting through hole 711, so that the pressing block 722 is just pressed on the surface of the cylinder body of the oil cylinder to be tested to form multi-point support.

Further, the pressing block 722 is movably connected with the rod 721, so that the pressing block 722 and the rod 721 can freely rotate relatively, and thus, when the rod 721 adjusts the axial position through rotation, the pressing block 722 cannot rotate along with the rod, and can keep contact with the surface of the cylinder.
In some embodiments, the number of the ram groups 72 included in the second cylinder support seat 70 is set to be 3 or more, specifically, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, … …, and the specific number may be set according to actual conditions, which is not limited herein.
