Abstract

The utility model belongs to the manufacture of pumps and motors in the technical field of hydraulic pressure, which solves the defects that in the existing closing-up mode, the equipment which is complicated has high cost, unstable pulling-out force and low qualification rate. The utility model is characterized in that a closing-up module (4) and a base (5) are respectively provided with conicity; a slipper (3) moves downwards in the module (4); due to the impediment of the module (4), the slipper (3) covers the surface of a plunger ball to obtain the purpose of combination. The utility model can be used for the manufacture factories and the non-manufacture factories of hydraulic pumps and hydraulic motors to manufacture and to repair plunger pumps and the plunger assemblies of the motors, which ensures that after closed up, the plunger pumps and the plunger assemblies of the motors have stable quality; the qualification rate reaches above 98%; the pulling-out force is higher than the prior art; the indexes of mobility and axial drunkenness are stable.

Description

Closing-up device for plunger assembly
The utility model is a kind of closing-up device, especially for oil hydraulic pump and the manufacturing of oil hydraulic motor plunger assembly and the plunger assembly closing-up device of reparation in hydraulics field.
Plunger assembly in pluger type hydraulic pump and the motor is a key part and component, the quality of plunger assembly directly influences the quality of oil hydraulic pump and motor, and the quality critical of plunger assembly is its closing in, mainly containing (1) bikini hydraulic rolling in the prior art closes up, its formation is a press, the top of hydraulic pressure bed compression leg plug (2), and plunger ball places in crawler shoe (3) ball-and-socket, to three closing in roller pressurizations the outside of crawler shoe (3) is under pressure by hydraulic press, plunger ball surface is contained.Its deficiency is, equipment requires complicated, frock manufacture cost height, and closing in quality and plunger pulling-out force instability, product percent of pass is low, and is can consumption high efficiency low, and for bigger plunger assembly, this closing in method still can not be satisfied the demand.
(2) hydraulic pressure closes up, and its formation is to make crawler shoe generation plastic deformation by pressure, reaches the purpose that plunger ball is contained, its deficiency is that the mould volume is big, makes more complicated, the cost height, its manufacturing technology is required height, also have closing in quality instability.
The purpose of this utility model is to remedy above-mentioned deficiency of the prior art, and provide a kind of structure simple especially, with low cost, the efficient height, energy saving, not tight to the hydraulic equipment requirement, be applicable to oil hydraulic pump oil hydraulic motor manufacturing firm, non-manufacturing firm makes, repairs the plunger assembly of plunger pump and motor and can guarantee its stay-in-grade plunger assembly closing-up device.
Technical solution of the present utility model is: be shaped on the tapering that both match respectively on closing in module (4) and pedestal (5), be convenient to the loading and unloading of crawler shoe.Module (4) places in the pedestal (5), crawler shoe (3) places in the module (4), press leads to the top of depresses plunger (2) and through guide way, institute exerts pressure and makes crawler shoe (3) motion downwards in module (4), make crawler shoe (3) produce plastic deformation plunger body ball surface is contained, reach the purpose of combination closing in.
The utility model has following advantage compared to existing technology:
1. structure is simple and practical especially, and is in light weight, easily processing, and required expense is not as good as a thousandth of prior art tooling device manufacturing expense.
2. not strict to the hydraulic equipment requirement, operating method is simple and easy to grasp.
3. be applicable to that oil hydraulic pump and oil hydraulic motor manufactory make the plunger assembly that plunger assembly and non-manufacturing firm repairing plunger pump and motor are changed.Can turn waste into wealth, especially to the repairing and the renewal of the plunger assembly of the pluger type hydraulic pump of the equipment introduced and motor, prolong the working life of imported hydraulic pump and motor greatly, its economic benefit is considerable, and is practical.
4. the most important thing is to guarantee the closing in steady quality of plunger assembly, up-to-standard rate is up to more than 98%, and plunger combination back pulling-out force is higher than prior art far away, and flexibility, technical orders such as axial float are also highly stable, solved a great problem that this technical field faces at present.
The drawing of accompanying drawing is described as follows:
This figure is an overall structure schematic representation of the present utility model.Wherein 1 is guide way, and 2 is plunger, and 3 is crawler shoe, and 4 are the closing in module, and 5 is pedestal.
The utility model is described in further detail below in conjunction with drawings and Examples: outside closing in module (4) and pedestal (5), inner side surface, be shaped on the tapering that both match respectively.Closing in module (4) is two hollow semicircles, has placed in the end cavity pedestal (5), and crawler shoe (3) places in the closing in module (4).Guide way (1) is a hollow, and the last plane of its lower plane and pedestal (5) is involutory.During use, pedestal (5) is placed on the platform, press only needs the top of depresses plunger (2) in a direction indicated by the arrow, and lead through guide way, crawler shoe (3) is motion downwards in module (4), by the obstruction of module (4), make crawler shoe (3) produce plastic deformation simultaneously, the purpose that reaches the combination closing in is contained on plunger ball surface.According to dissimilar plungers and crawler shoe, change corresponding with it closing in module (4) and guide way (1) and get final product.Module in this device (4) is crucial part, and its quality is the quality of decision closing in quality directly.The plunger assembly closing-up device can be used for oil hydraulic pump and oil hydraulic motor manufacturing firm and non-manufacturing firm new system, repairs the plunger assembly of plunger pump and motor.

Claims (4)

1, a kind of closing-up device, especially for the manufacturing of oil hydraulic pump and motor and the plunger assembly closing-up device in hydraulics field, by pedestal (5), crawler shoe (3) is formed, it is characterized in that, be closing in module (4) between pedestal (5) and crawler shoe (3), the last plane of the lower plane of guide way (1) and pedestal (5) is involutory.
According to the plunger assembly closing-up device described in the claim 1, it is characterized in that 2, closing in module (4) is two removable hollow semicircles, be shaped on the tapering that matches with the inner side surface of pedestal (5) at its outer side surface.
3, according to the plunger assembly closing-up device described in the claim 1, it is characterized in that, be shaped on the tapering that matches with the outer side surface of the module that closes up (4) at the inner side surface that end cavity pedestal (5) is arranged, the lower plane of the last plane of pedestal (5) and guide way (1) is involutory.
According to the plunger assembly closing-up device described in the claim 1, it is characterized in that 4, guide way (1) is a hollow.
