The guide deviation rectifying mechanism comprises a guide plate 8, a guide pillar 3 and a guide sleeve 6, wherein the guide plate 8 is movably connected with the loading frame 1 through the guide pillar 3 and the guide sleeve 6. The guide posts 3 are symmetrically distributed, so that the stability of guiding is improved.
The bottom of the loading frame 1 is firmly connected with a tested general plane through threaded connection, and the general plane is a general plane for horizontal loading of the hydraulic oil cylinder or a general plane for testing the rotary motion hydraulic oil cylinder, namely a tested general plane of the tested oil cylinder. The top surface of the loading frame 1 is fixed with a loading oil cylinder 2 in a threaded connection mode. A pin shaft 5 is hinged on a trunnion ball at the head of the loading oil cylinder 2, and a piston rod of the loading oil cylinder 2 is connected with a force transmission support 7 through the pin shaft 5. The guide plate 8 is positioned below the force transmission support 7, and under the action of the force transmission support 7, the guide plate 8 moves along the vertical axis direction of the loading oil cylinder 2 to correct small unbalance loading and form a force loading power part along the vertical axis direction of the device, so that a loading force for carrying out radial loading or unbalance loading on the tested oil cylinder is provided. The damping mechanism 13 is designed for a special locking and unlocking structure, locking and unlocking are realized according to working requirements, the rated load is large, one end of the damping mechanism 13 is fixed on the bottom surface of the loading frame 1, and the other end (a damping rod end) is connected with the radial loading or rotary loading stress in the opposite direction.
When the hydraulic oil cylinder which horizontally loads and linearly moves is subjected to radial load loading, an executing mechanism for radial load loading is a movable wheel force transmission pressing assembly 12. The connecting end of the movable wheel force transmission pressing assembly 12 is connected to the load cell 10, and the other end of the load cell 10 is connected with the guide plate 8 of the power loading part of the device. The movable wheel force transmission pressing assembly 12 is composed of a roller 19, a roller shaft 20, a roller seat 16 and a threaded connecting block 17, wherein one end of the roller shaft 20 is provided with the roller 19 through a bearing 22, the other end of the roller shaft is connected with the roller seat 16, and the roller seats 16 of the plurality of movable wheel force transmission pressing assemblies 12 are assembled through the threaded connecting block 17. In the non-operating state, the roller seat 16 of the movable wheel force transmission pressing assembly is connected with the anti-falling plate 14 on the loading frame 1 through screws, and the moving part of the device is prevented from falling under the action of gravity.
When radial load loading is carried out, loading oil pressure is applied to the loading oil cylinder 2, and a piston rod of the loading oil cylinder 2 retracts and extends. When a piston rod of the loading oil cylinder 2 slowly extends out, a roller of the movable wheel force transmission pressing assembly 12 gradually presses a stressed support at the rod end of the tested oil cylinder in a horizontal loading state, a radial load loading test is carried out on the tested oil cylinder, and loading data are collected by the collection system. Different from the loading oil cylinder 2 of the device, when a radial load loading test of the tested oil cylinder is carried out, another horizontal loading oil cylinder provides load for the tested oil cylinder along the horizontal direction (namely the axial direction of the tested oil cylinder), the load bearing capacity of the tested oil cylinder is tested, the load efficiency of the tested oil cylinder can be calculated, and the loading oil cylinder and the tested oil cylinder are connected together through a stress support and a guide mechanism between the loading oil cylinder and the tested oil cylinder.
The damping mechanism 13 is connected below the stressed support, and when the stressed support is stressed to move slowly, the damping mechanism 13 does not play a damping role. Because the tested cylinder has weak capability of bearing radial load, when the tested cylinder is used for testing the radial load, the loading cylinder 2 of the device is perpendicular to the stress support to apply the radial load, although a guide mechanism is arranged between the tested cylinder and the horizontal loading cylinder, the tested cylinder, the stress support and the horizontal loading cylinder can lose the position of the action line of movement along the horizontal direction, and the position of the radial action point of the loading cylinder 2 is rapidly deviated towards the outer side to cause the damage of one or two cylinders, thereby the connection is failed. When the horizontal force support of the tested cylinder, the stressed support and the horizontal loading cylinder suddenly fails, the damping mechanism 13 is under the action of impact load, the damping mechanism 13 is locked, and the damping mechanism 13 is equivalent to a rigid mechanism to support the failed connection, so that the damage of equipment and parts or the injury to personnel caused by sudden impact can be avoided.
When a holding torque measurement test is carried out on the rotary motion hydraulic oil cylinder, an actuating mechanism for providing holding torque is a rotary lever pressing fork 11, similarly, the connecting end of the rotary lever pressing fork 11 is connected to a force measuring sensor 10, and the other end of the force measuring sensor 10 is connected with a guide plate 8 of a device loading power part.

The rotating shaft end of the rotating movement hydraulic oil cylinder is connected with a rotating lever 26, the rotating lever 26 is in a horizontal state under a rated working condition during measurement, the vertical axis of the loading oil cylinder 2 is perpendicular to the horizontal force arm of the rotating lever 26, and the required distance of the force arm is kept. The stressed contact surface of the rotating lever 26 and the stressed contact surface of the rotating lever pressure fork 11 are gradually-changed smooth curved surfaces, so that the loading part of the loading oil cylinder 2 can perform pressurized motion along the vertical axis direction. When the rotating lever 26 moves in an accelerated mode, the damping mechanism 13 is locked, and is equivalent to a rigid mechanism to support the rotating lever 26, so that the supporting function is realized, and the rotating lever 26 under the rated load working condition is supported and is not moved in a horizontal state.
When the piston rod of the loading oil cylinder 2 slowly extends out, a load is vertically and downwards applied to the upper part of the rotating lever 26 through the rotating lever pressing fork 11, the loading load is adjusted from small to large, the special damping mechanism is unlocked because the loads in the positive direction and the negative direction borne by the damping mechanism 13 are balanced, the damping mechanism 13 is unlocked, and meanwhile, when the loading load applied to the loading oil cylinder 2 through the rotating lever pressing fork 11 is gradually increased to be enough to overcome the torsion force of the rotating lever 26, the rotating lever 26 changes the static balance state and rotates instantly. According to the definition of the holding torque, the torque value of the rotary oil cylinder in the transient rotation state is the holding torque value under the rated working condition when the static balance state is changed, namely the value of the holding torque of the rotary oil cylinder can be obtained according to the length value of the force arm of the rotary lever 26 multiplied by the loading load.
The utility model discloses a damping mechanism 13's advantage is guaranteeing not to cause the damage of device loading part because of sudden impact. In other embodiments, the utility model discloses also can not use damping mechanism 13 to keep the torque measurement, hold rotatory lever 26 with fixed bearing support, load cylinder 2 exerts the load perpendicularly downwards above rotatory lever 26, with the load from little to big adjustment, when rotatory lever 26 instantaneous rotation, can be according to the size calculation of load cylinder holding torque size.
