Description
Technical field
The utility model relates to jack fields, and in particular to a kind of jack piston rod sleeve pressing machine.
Background technique
Jack needs to be pressed into guide sleeve in piston rod part aperture during assembling, since guide sleeve and aperture are cooperation
Connection, traditional-handwork assembly needs gradually to knock in guide sleeve in a manner of manually tapping in the aperture of piston rod, not only time-consuming to take
Power, and be easy guide sleeve structure is damaged, influence using.And tap by hand, the size and Orientation of percussion power takes completely
Certainly in the experience of operator, the stability of product assembly quality can not be ensured.
Summary of the invention
The technical problem to be solved by the present invention is to provide a kind of jack piston rod sleeve pressing machines, are automatically performed guide sleeve
Press fitting operation, not only increases assembly efficiency, and assembly precision also can effective guarantee.
In order to solve the above-mentioned technical problem, a kind of the technical scheme that the utility model is provided is as follows: jack piston rod pressure
Set machine, including rack, the rack include workbench and the crossbeam above workbench；The upper surface of the workbench is set
There is positioning mold；The crossbeam is equipped with mandril and drives mandril flexible driving device up and down, the free end of the mandril with
Positioning mold is corresponding；The free end releasable connection of the mandril has a press-loading head made of ferrimagnet, outside the press-loading head
It is arranged adjusting sleeve made of resilient material；It further include the magnet being arranged between mandril and press-loading head.
When carrying out guide sleeve press fitting, the end of piston rod is inserted into positioning mold first, so that the aperture end of piston rod
Upward.Then guide sleeve is set in outside adjusting sleeve, and is connect under the magneticaction of magnet with press-loading head.And then driving device
Work, guide sleeve are pressed into the aperture of piston rod end with mandril, complete the press fitting of guide sleeve.Compared with existing assembly method, lead
Set is connect with press-loading head magnetism, is not necessarily to worker's manual alignment and support, under the premise of guaranteeing to middle requirement, worker is avoided to press
Safety accident occurs during set.Since guide sleeve and the accuracy of alignment during piston rod press fitting are more demanding, and piston rod
All there is certain installation error between mold, guide sleeve and press-loading head, so also certainly existing between guide sleeve and piston rod
The error of centralization.During press fitting, when guide sleeve and plunger rod contacts, chamfer contact and production of the guide sleeve with piston rod tapping
Raw radial active force, forces guide sleeve to squeeze adjusting sleeve, and adjusting sleeve is deformed, and finally makes guide sleeve and piston rod centering quasi-
Really, it is ensured that assembly precision.
Preferably, the adjusting sleeve includes guide section and adjustment section, the adjustment section is arranged close to mandril；It is described
The outer diameter of guide section is gradually reduced from close to mandril one end to the other end.
Preferably, the positioning mold and workbench releasable connection.Convenient for the maintenance and replacement of positioning mold.
Preferably, the driving device is cylinder.
Preferably, the positioning mold upper surface is equipped with positioning chamber, and fixed equipped at least one in the positioning chamber
Position step.The bottom surface of positioning chamber and step surface are respectively positioning surface, to adapt to the piston rod of various outer diameter, improve the suitable of sleeve pressing machine
Use range.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the present embodiment jack piston rod sleeve pressing machine；
Fig. 2 is the main view of the present embodiment jack piston rod sleeve pressing machine；
Fig. 3 is the partial enlarged view in Fig. 2 at A；
Fig. 4 is the structural schematic diagram that the present embodiment jack piston rod sleeve pressing machine is pressed state.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
Embodiment
As depicted in figs. 1 and 2, a kind of 7 sleeve pressing machine of jack piston rod, including rack, the rack include workbench 1
With the crossbeam 3 for being located at 1 top of workbench；The upper surface of the workbench 1 is equipped with positioning mold 6；The crossbeam 3 is equipped with mandril
5 and the driving device 4 stretched of about 5 mandril of driving, the free end of the mandril 5 is corresponding with positioning mold 6.
As shown in Figures 2 and 3, the free end releasable connection of the mandril 5 has press-loading head 2 made of ferrimagnet, institute
Adjusting sleeve made of elastic material is arranged with outside the press-loading head 2 stated；The adjusting sleeve includes guide section 23 and adjustment section 22, institute
The adjustment section 22 stated is arranged close to mandril 5；The outer diameter of the guide section 23 is gradually reduced from close to 5 one end of mandril to the other end.
Accuracy of alignment during being pressed due to guide sleeve 8 with piston rod 7 is more demanding, and piston rod 7 and mold, guide sleeve 8 and press-loading head 2
Between all there is certain installation error, so also certainly existing the error of centralization between guide sleeve 8 and piston rod 7.In press fitting
In the process, when guide sleeve 8 and piston rod 7 contact, the chamfer contact of guide sleeve 8 and 7 tapping of piston rod simultaneously generates radial effect
Power forces guide sleeve 8 to squeeze adjusting sleeve, and adjusting sleeve is deformed, and finally makes guide sleeve 8 and 7 centering of piston rod accurate, it is ensured that dress
With precision.It further include the magnet 21 being arranged between mandril 5 and press-loading head 2.Compared with existing assembly method, guide sleeve 8 and pressure
The magnetic connection of head 2 is filled, worker's manual alignment and support is not necessarily to, under the premise of guaranteeing to middle requirement, avoids worker in pressing sleeve
Safety accident occurs in the process.
As shown in Figure 2, Figure 3 and Figure 4, when carrying out the press fitting of guide sleeve 8, positioning mold 6 is inserted into the end of piston rod 7 first
It is interior, so that the aperture end of piston rod 7 is upward.Then guide sleeve 8 is set in outside adjusting sleeve, and under the magneticaction of magnet 21 with
Press-loading head 2 connects.And then driving device 4 works, and guide sleeve 8 is pressed into the aperture of 7 end of piston rod with mandril 5, completes guide sleeve 8
Press fitting.
As depicted in figs. 1 and 2, further, the positioning mold 6 and 1 releasable connection of workbench.Convenient for positioning mold
6 maintenance and replacement.6 upper surface of positioning mold is equipped with positioning chamber, and at least one positioning is equipped in the positioning chamber
Step.The bottom surface of positioning chamber and step surface are respectively positioning surface, to adapt to the piston rod 7 of various outer diameter, improve the suitable of sleeve pressing machine
Use range.
Above-described jack piston rod sleeve pressing machine, jack piston rod sleeve pressing machine are automatically performed the press fitting behaviour of guide sleeve
Make, not only increases assembly efficiency, and assembly precision also can effective guarantee.
In short, the above is only the preferred embodiment of the utility model only, it is not intended to limit the utility model, it is all
Any modifications, equivalent replacements, and improvements made within spirit of the present utility model and principle etc. should be included in practical
Within novel protection scope.
