Description
Technical field
The utility model relates to a kind of tool mechanisms for hydraulic pump swash plate wear test, and it is real to belong to hydraulic pump components
Test tooling field.
Background technique
Swash plate is an important part for influencing hydraulic variable flow pumpage regulation performance, as shown in Figure 1.In entire hydraulic change
During measuring pump work, the conciliation of hydraulic pump discharge is realized by the swing of swash plate, the mill of two arc surfaces of swash plate
Damage amount and wear form will directly affect the service life entirely pumped.
Occur more rapid wear and plucking phenomenon in the use process of swash plate at present.Pass through analysis, the mill of swash plate
Damage is mainly related with arc surface and its cooperation profile tolerance of a surface, the support oil groove area on roughness, hardness and swash plate.Swash plate portion
The raising of the machining accuracy and hardness of part will will cause the different degrees of raising of production cost, support the control of oil groove area to life
Produce cost influence it is relatively small, but the change of oil groove the leakage of hydraulic pump will be had an impact and also will cause swash plate by
Very big deflection torque, it will increase the abrasion of another side.
Summary of the invention
Technical problem to be solved by the utility model is: solving the abrasion for how avoiding occurring in the use process of swash plate
The problem of too fast and plucking phenomenon.
In order to solve the above-mentioned technical problem, there is provided one kind for hydraulic pump swash plate mill for the technical solution of the utility model
Damage the tool mechanism of experiment, which is characterized in that including sliding plate, sliding plate is equipped with oval-shaped groove, and being equipped in oval-shaped groove can
With the straight pin of sliding, one end of straight pin and connecting rod is connected, and the outside of connecting rod is equipped with guide sleeve, guide sleeve and guide rod
Interference connection, the other end and inclination pin connection of connecting rod, the end of angled pin is equipped with the swash plate that can be swung, swash plate and plunger
Piston shoes connection, plunger piston slippery boots are set in cylinder body, and cylinder body is equipped with the pipe fitting connected with plunger piston slippery boots, pipe fitting and second pressure
Oil pipe is connected.
Preferably, the connecting rod is threadedly coupled with straight pin；Connecting rod is slidably connected with guide sleeve；Connecting rod with incline
Taper pin is threadedly coupled.
The utility model is simple compared with machine assembly experiment installation to save the time, it is known that swash plate is not by maximum support force
Become, by pressure formula F=PA it is found that swash plate support force is related with pressure and bearing area, the change of supporting surface needs to add
Work obtains, the influence that the utility model can wear swash plate by changing the pressure experiment difference support force of external pressure oil；?
In experimentation because the tool mechanism of the utility model be it is non-closed, can by visually see under different support forces swash plate with
The hydraulic oil amount of leakage of supporting table contact surface, can be the same as the amount of leakage under the different support forces for crossing measuring cup collection leakage oil droplet.
