Description
Technical field
The present invention relates to one kind to tap frock, and especially a kind of steering gear ball, which rises, taps frock, also relates to its application method, 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 the significant points that it is connected with main frame that hydraulic steering gear, which has the end face of four hydraulic fluid ports, to ensure reliably to seal after assembling, avoids permeability phenomenon, the end face does not allow the defects of colliding with scuffing be present.But when assembling, the end face needs of steering gear tap hammer percussion press-in press fitting and risen by ball of the overcoat center counterbore equipped with steel ball.Production practices show, the press fitting that the ball rises is easy to leave scar in end face, because ball rises smaller, during with tapping hammer percussion press-in, the result that hammer injures end face is tapped it is difficult to avoid producing because striking askew deflection, for a long time, this problem fails to be properly settled always, so as to influence the assembling quality of steering gear and using effect.
The content of the invention
It is an object of the invention to：In view of the above-mentioned problems of the prior art, proposing that a kind of steering gear ball that can prevent steering gear facet damage, ensure assembling quality rises taps frock, while provide its application method.
In order to reach object above, the present invention steering gear ball rise tap frock include on the basis of bottom surface face panel, the panel has four positioning holes with the hydraulic fluid port position correspondence of steering gear end face four respectively, and spacing pin described in fixed spacing pin is inserted in the positioning hole with the fork for stretching out reference plane；The panel corresponds to ball and rises by rigging position with percussion hole, the connecting pole above panel is extended in the percussion hole, the connecting pole small big inner bore of step under having, the top of the endoporus is equipped with the compression leg for moving cooperation therewith, extend and the dynamic pad coordinated in endoporus bottom the lower end of the compression leg, compression leg is resisted against equipped with upper end in the endoporus, lower end is resisted against the spring of connecting pole, the upper end of the connecting pole is equipped with the stop collar for covering compression leg, and the percussion block through stop collar is extended in the upper end of the compression leg.
In use, comprise the following steps that：
The first step, ball, which rises, to be placed in steering gear end face and needs pushed position；
Second step, the fork of four spacing pins of panel is respectively aligned in oilhole corresponding to steering gear end face and pushed, until the reference plane of panel is bonded with steering gear end face, pad lower end, which is trapped the ball, rises；
3rd step, impact taps block downwards, until ball rises and is pressed into steering gear end face.
Only rise due to the lower end of pad with ball and contact, steering gear end face will not be encountered, therefore even if tapping repeatedly, also steering gear end face will not be damaged, and pad is connected the constraint of post endoporus, all the time in plumbness, tap anyway, can only produce the vertical active force to rise to ball, avoid its deflection.Therefore, it after using the present invention, can thoroughly avoid steering gear facet damage, ensure to assemble quality.
Brief description of the drawings
Fig. 1 is the structural representation of one embodiment of the invention.
Fig. 2 is Fig. 1 top view.
Fig. 3 is the structural representation of steering gear.
Fig. 4 is Fig. 3 sectional view.
Embodiment
The steering gear ball of the present embodiment, which rises, taps frock as depicted in figs. 1 and 2, the face on the basis of bottom surface of panel 2, with four positioning holes with the hydraulic fluid port position correspondence of steering gear end face shown in Fig. 3 P, T, A, B tetra- respectively, the fixed spacing pin 1 of inserting, spacing pin 1 have the fork for stretching out reference plane respectively in each positioning hole；The internal diameter of the diameter of fork and each hydraulic fluid port matches, more than the diameter of the spacing inserting paragraph of pin 1, therefore being capable of reliable location.The corresponding ball of panel 2 rigging position that rises has and makes female percussion hole, and there is externally threaded connecting pole 3 to twist as the percussion hole is fixed for lower end, and the upper surface of panel 2 is extended in its upper end.Connecting pole 3 has epimere tapered from top to bottom, stage casing, hypomere three-level inner bore of step, the epimere on the endoporus top is equipped with the compression leg 6 for moving cooperation therewith, the lower end of compression leg 6 extend with the dynamic pad 5 coordinated of the hypomere of endoporus bottom, the stage casing of endoporus is resisted against compression leg 6 equipped with upper end, lower end is resisted against the spring 4 of connecting pole end surface of step hole.The lid stop collar 7 for covering compression leg 6 is fixedly mounted in the upper end of connecting pole 3, and the upper end of compression leg 6 is to extend the percussion block 8 through stop collar 7.Tap block 8 to be made up of the percussion disk 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.
In use, as shown in Figure 3 and Figure 4, comprise the following steps that：
The ball that the first step, Q that ball rises are placed in steering gear end face M and need to be pressed into rises at hole；
Second step, the fork of four of panel 2 spacing pins 1 is respectively aligned in oilhole P, T, A, B corresponding to the M of steering gear end face and pushed, until the reference plane of panel 2 is bonded with steering gear end face M, the lower end of pad 5 is trapped the ball the Q that rises；
3rd step, impact taps block 8 downwards, until ball rises, Q is pressed into steering gear end face M.
After the frock of the present embodiment, because in assembling process, the lower end of pad can not possibly encounter steering gear end face, therefore percussion will not damage the end face, ensure that the sealing after steering gear installation.And tap block and pad has the vertical bullport to match respectively, ensure that the vertical active force for tapping and rising to ball, effectively prevent deflection, it is ensured that assembling quality.
