2, this frock does not have stopping means, seam by the second pressure head 15 when forcing press presses down is spacing, can't offset the mismachining tolerance of piston 2 and protruding bulb 3, also with regard to uncontrollable height dimension, cause the height of the stroking mechanism after withholding not reach requirement, inclusion tightness and the end play of recessed ball-and-socket and protruding bulb are inconsistent, cause easily defective work;
3, the die seam split of the two halves of this frock is straight, and the shape after the pressing is not regular, and the size of bag mouthful can't guarantee;
Summary of the invention
The purpose of this utility model is to solve in the bag ball process, the size that cause easily defective work, can't guarantee to wrap mouthful, cause the injured problem of hand easily, provide a kind of assembling not only fast but also the assembly tooling of safety, hydraulic motor stroking mechanism that operation possibility is high.
In order to achieve the above object, the utility model provides a kind of assembly tooling of hydraulic motor stroking mechanism, comprise forcing press workbench and press ram, be provided with protruding bulb between forcing press workbench and the press ram, protruding bulb is provided with the variable piston, it is characterized in that, described forcing press workbench top is provided with base, base is connected with fairlead, also be provided with groove on the centre position of base, be provided with back-moving spring in the groove, protruding bulb and shaped block, and back-moving spring, protruding bulb and shaped block all are complementary with groove, back-moving spring is connected with shaped block by protruding bulb, be provided with the variable piston in the shaped block, and shaped block and variable piston be complementary, be provided with the first pressure head in the fairlead, one end of the first pressure head is connected with the variable piston, and the other end of the first pressure head is connected with press ram.
Preferably, be provided with scroll chuck between described forcing press workbench and the base.
Preferably, described shaped block is located between base and the fairlead, and shaped block and fairlead are complementary.
Preferably, be provided with optional dress cushion block between described fairlead and the press ram.
The utility model provides a kind of fast again assembly tooling of safety, reaches the fine inclusion of recessed ball-and-socket and protruding bulb, improves the qualification rate of withholding the bag ball.
Specific as follows:
1, on the basis of traditional frock, increased base, with the base clamping in the scroll chuck of forcing press, the centering effect the when pressure head that has played forcing press press-fits;
2, the end face of protruding bulb is attached in the groove of base, has played good positioning action, simultaneously need not improve safety coefficient with hand steered part, and operation possibility improves greatly;
3, increase back-moving spring in the stepped recesses of base, can play good reset effect, after the pressing assembly is ejected, the convenient taking-up, the shaped block that those secondary two halves are split after also having prevented from simultaneously withholding is stuck in the base, cannot take out;
4, the size of optional dress cushion block can be made different size according to the height tolerance of the stroking mechanism after the assembling, so that can guarantee after press-fiting that the variable piston is consistent with the end play of protruding bulb, has greatly improved the qualification rate of withholding;
5, the secondary two halves shaped block of splitting is that structure according to stroking mechanism designs, more the fit distortion of shirt rim behind the bag ball of the die of splitting compared with original secondary two halves, thereby so that the closing in shape of bag ball is unified, with protruding bulb well inclusion get up.

The specific embodiment
For the utility model is become apparent, hereby with preferred embodiment, and cooperate accompanying drawing to be described in detail below.
The utility model is a kind of assembly tooling of hydraulic motor stroking mechanism, as shown in Figure 2, is a kind of structural representation of assembly tooling of hydraulic motor stroking mechanism.With base 11 clampings in the scroll chuck 13 of forcing press workbench 5, back-moving spring 12 is placed on groove 14 inner bottom parts of base 11, and both are complementary, and the end face of protruding bulb 3 is placed on the ground floor step in the groove 14, and the slotted eye size of the size of protruding bulb 3 and this layer step is complementary.The shaped block 10 that one secondary two halves are split is placed on the second layer step in the groove 14, and the slotted eye size of the size of shaped block 10 and this layer step is complementary, and so that the spherical part of protruding bulb 3 passes the hole of shaped block 10 centres.14 pairs of back-moving springs 12 of groove, protruding bulb 3, shaped block 10 all play the effect that limits the position.Variable piston 2 is vertically placed in the shaped block 10 of protruding bulb 3 tops, variable piston 2 is complementary with shaped block 10, the fairlead 9 that the first pressure head 7 is equipped with in inside is enclosed within the outside of shaped block 10, and be connected with base 11, in the space of shaped block 10 between base 11 and fairlead 9, shaped block 10 is complementary with fairlead 9.Optional dress cushion block 8 is installed between fairlead 9 and the press ram 6, and the end that choosing fills suitable optional dress cushion block 8, the first pressure heads 7 according to the height dimension of variable structure is connected with variable piston 2, and the other end of the first pressure head 7 is connected with press ram 6.
The utility model is specially adapted to the bag ball assembling of recessed ball-and-socket and protruding bulb.Press ram 6 pushes away the first pressure head 7, the first pressure heads 7 downwards and drives variable pistons 2 and move down, until press ram 6 when running into suitable optional dress cushion block 8, just having been finished the bag ball task that closes up automatically.
Skirt mouth pattern behind protruding bulb 3 inclusions of the identical stroking mechanism of the shape of the shaped block 10 that a pair is partly split in the utility model, distortion becomes the skirt mouth because extruding metal extends to have solved better the material at variable piston 2 bags mouthful place behind the bag ball, thus with protruding bulb 3 well inclusion get up.Place back-moving spring 12 in groove, the reverse impulse force after the pressing is convenient to the material returned; Optional dress cushion block 8 meets the height tolerance demand of stroking mechanism; Fairlead 9 has played position-limiting action, has improved the qualification rate of product.
The utility model is a kind of assembly tooling of hydraulic motor stroking mechanism, improved original old-fashioned structure, because base 11 is larger than the volume of protruding bulb 3, cancelled the scroll chuck 13 among the embodiment 1, holding base 11 by hand press-fits, also than original old-fashioned structural safety, be more suitable for the demand of hommization.Other are identical with embodiment 1.
