1, for withholding for piston shoes 2 and plunger 3.
The piston shoes buckle tool 1 includes the pedestal 11 with accommodating space 110, spring pad 13, molding block 15, Yi Jishe
Withhold mechanism 17 in 11 top of the pedestal, the spring pad 13 be set to the bottom of the pedestal 11 and with the pedestal 11 it
Between by 12 elastic connection of the first spring, the molding block 15 is set in the pedestal 11 and passes through the between the pedestal 11
Two springs, 14 elastic connection, the plunger 3 are placed on the spring pad 13, and the piston shoes 2 are placed on the plunger 3, institute
It states molding block 15 and is located on the plunger 3, described withhold after mechanism 17 pushes the piston shoes 2 is further continued for pushing the molding block
15, so that the molding block 15 elastic shrinkage inwardly downward, until the plunger 3 and piston shoes 2 close up.
The pedestal 11 is including bottom plate 111, the lower module 112 on the bottom plate 111 and is set to the lower module
The center of upper end cover 113 on 112, the lower module 112 and upper end cover 113 be it is hollow, the bottom plate 111, lower module 112,
Upper end cover 113 forms the accommodating space 110, and when the plunger 3 is assembled with piston shoes 2, it is empty that the plunger 3 is placed in the receiving
Between in 110, by 11 automatic centering of pedestal, positioning can be played the role of.
The bottom plate 111 and the lower module 112 are preferably fixedly connected by screw 114, structure is simple, it is easy to disassemble,
It is fixed.
As shown in Figure 1, the bottom plate 111 is equipped with the groove to be formed that is recessed inwardly, institute close to the surface of the lower module 112
The first spring 12 is stated in the groove, space can be saved, entire 1 more compact structure of piston shoes buckle tool.
The spring pad 13 is set on first spring 12, passes through the bottom plate of first spring 12 and the pedestal 11
Elastic connection between 111, when assembly, the plunger 3 was placed on the spring pad 13, the spring pad 13 and first bullet
Spring 12 provides pressure buffer for the piston shoes 2 and the assembly of plunger 3, keeps being flexibly connected between the piston shoes 2 and plunger 3, be allowed to
Stress is more evenly；When assembled, the mechanism 17 of withholding removes pressure, and first spring 12 can be restored to original position
It sets, the position of the piston shoes 2 and plunger 3 assembled is raised, convenient for being drawn off.
In the present embodiment, the spring pad 13 is the T-type spring pad being made of horizontal arm and vertical arm, as shown in figure 3,
When it is described withhold mechanism 17 and compress the piston shoes 2 and plunger 3 when, the cross-sectional length of the horizontal wall is greater than the section of the groove
Length, i.e., the horizontal ledge of the spring pad 13 is set on the groove at this time, to withhold the pushing of mechanism 17 described in control
Distance, the spring pad 13 also act as certain insulation blocking effect, prevent it is described withhold the pushing of mechanism 17 and transfinite, described in damage
First spring 12 or the plunger 3.
The molding block 15 is a kind of mold for the piston shoes 2 and auxiliary molding when the assembly of plunger 3, under described
The top of module 112 is abutted with the inner wall of the upper end cover 113, described when the plunger 3 is placed in the pedestal 11
Molding block 15 is located on the plunger 3.
By 14 elastic connection of second spring between the molding block 15 and the pedestal 11, when the piston shoes 2 with
When the plunger 3 assembles, it is described withhold mechanism 17 downward pressure be provided first act on the piston shoes 2, after pushing certain distance
It acts on the molding block 15,15 retracted downward of molding block, the second spring 14 buffers in the vertical direction at this time
The pressure for withholding mechanism 17 makes the pressure stepless action in the piston shoes 2 and plunger 3, keeps the piston shoes 2 and plunger
It is flexibly connected between 3, is allowed to stress more evenly, by fit-up gap control in stable range, improve assembly efficiency.
As shown in figure 4, Fig. 4 is cross-sectional view of the piston shoes buckle tool shown in Fig. 3 along line A-A.Further, the molding block
Third spring 151 is equipped in 15, when it is described withhold mechanism 17 and push the molding block 15 when, the molding block 15 at the same downwards to
Interior elastic shrinkage；The third spring 151 also buffers the pressure for withholding mechanism 17 in the horizontal direction, cuts down institute
The pressure in molding block 15 is stated, can be prolonged its service life, the second spring 14 and third spring 151 are by the buckle machine
The pressure of structure 17 buffers in different directions, and function and effect are more preferable, and the assembly efficiency of the piston shoes 2 and plunger 3 is high, closing in quality
Stabilization, qualification rate are higher.
As shown in Figures 2 and 3, the mechanism 17 of withholding includes pressure head 171, the ejector beam in the pressure head 171
172, it is located in the transition sleeve 173 between the pressure head 171 and the ejector beam 172, is located in the transition sleeve 173 and described
Fastener 174 between ejector beam 172 and the nut 175 in the pressure head 171.
The pressure head 171 provides downward pressure under the action of press machine；The ejector beam 172 is for withholding the cunning
Boots 2 and plunger 3；The transition sleeve 173 is used for the middle transition of the pressure head 171 and ejector beam 172, is preferably steel bushing, leads to
The techniques such as over mechanical processing, heat treatment, steel bushing is more wear-resistant, impact resistance, intensity are good；The fastener 174 is used for will be described
Ejector beam 172 is installed in the transition sleeve 173, fills gap between the two；The nut 175 passes through the 4th spring 176
It is connect with the ejector beam 172, for adjusting pretightning force；4th spring 176 plays certain buffering in the vertical direction
Effect, so that the pressure of the ejector beam 172 uniformly acts on the piston shoes 2 and plunger 3, while the 4th spring
176 intensity is greater than first spring 12, so that described when withholding mechanism 17 and pushing, first spring 12 is preferentially shunk.
When assembly, the plunger 3 is placed in the pedestal 11, the ball-and-socket part of the piston shoes 2 and the plunger 3
Bulb partial preliminary is cooperated, and then the pressure head 171 for withholding mechanism 17 provides downward pressure by press machine, described
Ejector beam 172 first pushes the piston shoes 2, and active force is transferred to the plunger 3, so that 13 stress of the spring pad moves downward,
Compress first spring 12, then the pressure head 171 continues to push the molding block 15 so that the molding block 15 simultaneously to
Inside elastic shrinkage down, until the plunger 3 and piston shoes 2 close up, the spring pad 13 is abutted with the bottom plate 111 at this time, nothing
Method moves still further below.
In the present embodiment, the pressure of the pushing from 0 increase to 8.5KN when pressure release, the piston shoes 2 and plunger 3 after closing in
Axial gap be stable at 0.01~0.04mm, the angle that freely swings of the piston shoes 2 reaches 15 °~20 °, through pull-off test machine
Carry out pull-off test verifying, pulling-out force > 4000N, the skid shoe type plunger assembly axial mobility that the piston shoes 2 are assembled with plunger 3
Small, spherical deformation is small, and closing in quality is stablized.
The utility model is limited it should be noted that above-described embodiment illustrates rather than the utility model
System, and those skilled in the art can be designed alternative embodiment without departing from the scope of the appended claims.?
