Description
Technical field
This utility model relates to a kind of frock that taps, and especially a kind of steering gear ball rises percussion frock, belongs to mechanical assembly technique field.
Background technology
Hydraulic steering gear is a kind of hydraulic actuator being generally used on engineering machinery, agricultural machinery etc..It is its significant points being connected with main frame that hydraulic steering gear has the end face of four hydraulic fluid ports, for guaranteeing to reliably seal after assembling, it is to avoid permeability phenomenon, this end face does not allow existence to collide with the defects such as scuffing.But when assembling, these end face needs of steering gear tap to hammer into shape to tap to press-fit and are risen equipped with the ball of steel ball by overcoat central authorities counterbore.Production practices show, what this ball rose press-fit is easy to leave scar at end face, because ball rises less, with when tapping hammer percussion press-in, it is difficult to avoid producing because striking askew deflection tapping hammer the result injuring end face into shape, for a long time, this problem fails to be properly settled always, thus affects assembling quality and the using effect of steering gear.
Utility model content
The purpose of this utility model is: the problem existed for above-mentioned prior art, proposes a kind of to stop steering gear facet damage, guarantee that the steering gear ball assembling quality rises percussion frock, provides its using method simultaneously.
In order to reach object above, steering gear ball of the present utility model rise percussion frock include the panel in face on the basis of bottom surface, described panel has four holes, location corresponding with steering gear end face four hydraulic fluid port position respectively, and in hole, described location, plug-in mounting is fixed spacing pin described in spacing pin and had the fork stretching out datum level；The described panel correspondence ball rigging position that rises has percussion hole, the connection post above panel is extended in described percussion hole, described connection post is little big inner bore of step under having, the top of described endoporus is equipped with the dynamic compression leg coordinated therewith, the lower end of described compression leg is extended and is moved, with endoporus bottom, the pad coordinated, be resisted against compression leg equipped with upper end in described endoporus, lower end is resisted against the spring connecting post, the upper end of described connection post is equipped with covering the stop collar of compression leg, and the percussion block through stop collar is extended in the upper end of described compression leg.
During use, specifically comprise the following steps that
The first step, being risen by ball is placed in steering gear end face and needs pushed position；
Second step, the fork of four spacing pins of panel is respectively aligned in the oilhole that steering gear end face is corresponding and under press, until the datum level of panel and steering gear end face are fitted, trap the ball and rise in pad lower end；
3rd step, downwards impact tap block, until ball rises is pressed into steering gear end face.
Only rising with ball due to the lower end of pad and contact, steering gear end face will not being encountered, even if the most repeatedly tapping, also will not damage steering gear end face, and pad is connected the constraint of post endoporus, is in plumbness all the time, in any case tap, the vertical active force that ball is risen all can only be produced, it is to avoid its deflection.Therefore, after using this utility model, can thoroughly avoid steering gear facet damage, guarantee to assemble quality.

Detailed description of the invention
The steering gear ball of the present embodiment rises by percussion frock as depicted in figs. 1 and 2, panel 2 face on the basis of bottom surface, there are four holes, location corresponding with steering gear end face shown in Fig. 3 P, T, A, B tetra-hydraulic fluid port positions respectively, in hole, each location, plug-in mounting fixes spacing pin 1 respectively, and spacing pin 1 has the fork stretching out datum level；The diameter of fork and the diameter compatible of each hydraulic fluid port, more than the diameter of spacing pin 1 inserting paragraph, therefore, it is possible to reliably position.The corresponding ball of panel 2 rigging position that rises has the female percussion hole of system, and lower end has externally threaded connection post 3 and twists as fixed in this percussion hole, and the upper surface of panel 2 is extended in its upper end.Connect post 3 and there are the most tapered epimere, stage casing, three grades of inner bore of step of hypomere, the epimere on this endoporus top is equipped with the dynamic compression leg 6 coordinated therewith, the lower end of compression leg 6 is extended the hypomere with endoporus bottom and is moved the pad 5 coordinated, and the stage casing of endoporus is resisted against compression leg 6 equipped with upper end, lower end is resisted against the spring 4 connecting post end surface of step hole.The upper end fixed installation connecting post 3 covers the lid stop collar 7 of compression leg 6, and the upper end of compression leg 6 is to extend the percussion block 8 through stop collar 7.Tapping block 8 to be made up of the percussion dish of upper end and the cylinder percussion handle of bottom, the punch inside diameter of external diameter and stop collar 7 that cylinder taps handle matches.
During use, as shown in Figure 3 and Figure 4, specifically comprise the following steps that
The first step, the Q that risen by ball are placed in the ball that steering gear end face M need to be pressed into and rise at hole；
Second step, the fork of four of panel 2 spacing pins 1 is respectively aligned in steering gear end face M corresponding oilhole P, T, A, B and under press, until the datum level of panel 2 and steering gear end face M fit, trap the ball the Q that rises in the lower end of pad 5；
3rd step, downwards impact tap block 8, until ball rises, Q is pressed into steering gear end face M.
After using the frock of the present embodiment, owing to, during assembling, steering gear end face can not be encountered in the lower end of pad, therefore taps and will not damage this end face, ensures that the sealing after steering gear installation.And tap block and pad is respectively provided with the vertical bullport matched, it is ensured that tap the vertical active force that ball is risen, effectively prevent deflection, it is ensured that assembling quality.
