Description
Technical field
The invention belongs to technical field of tooling clamps, specifically, relate to a kind of dismounting frock that is used for automobile engine piston rod part piston pin
Background technology
The piston rod part of engine is made up of piston, connecting rod and piston pin usually.By piston pin is fitted together piston and connection rod set.Piston pin and connecting rod form interference fit when fitting together, and two of piston pin and piston can relatively rotate and make piston and connecting rod form the semifloating state.In the process that piston, connecting rod and piston pin are assembled together, generally be that small end of connecting rod heating back is pressed into piston pin fast with press at existing this semi-floating piston rod part assembling.This assembling mode is with the disposable small end of connecting rod that is pressed into of piston pin.Because piston adopts the aluminum alloy materials anti-pressure ability poor, it will bear assembling pressure in the assembling, and connecting rod is in quick condition, so the setting of press pressure can not be too big in the assembling.Because of destabilizing factors such as the fluctuation that has variation, the lathe pressure of the assembly parts magnitude of interference in the assembling inevitably, rapid cooling, assembler's action after the connecting rod heating are discontinuous, the part piston pin is not assembled to correct position.
Because of a variety of causes causes the situation that piston pin accurately can not be seated, just need take out piston pin and assemble once more or adjust by the press intensified pressure this moment at above-mentioned.Usually the way that piston pin is taken out is to utilize a push rod suitable with the piston pin diameter, aims at piston pin for one.Piston pin is pounded out in artificial other end of using hammer to aim at push rod.Usually can damage assembly and pull down piston pin by the adjustment of press intensified pressure or the method for manually knocking.Reason is that the inaccurate continuation intensified pressure adjustment of the equipment of itself causes error to strengthen probably, thereby makes the more difficult taking-up of piston pin.Even if the method for manually knocking dismounting then since inconsistent the making of artificial amount of force inequality, direction can take out piston pin but tend to cause the damage of piston pin.Because it is very high that itself requires the accuracy of piston rod part, in case damage is arranged then generally all can only scrap.Cause the waste of resource and the increase of cost.
Summary of the invention
For solving above technical problem, the object of the present invention is to provide a kind of can be with assembling piston pin not in place at the tool for dissembling piston pins of electric generator that does not damage under the situation of itself its taking-up.
Technical scheme of the present invention is as follows:
A kind of tool for dissembling piston pins of electric generator, it comprises base, gripper shoe, jack, on described base, vertically be fixed with a pair of guide-track groove that is parallel to each other, described gripper shoe two ends are inserted in the guide-track groove that be arranged in parallel and can move up and down along described guide-track groove, be set with the guiding pole socket on the described gripper shoe, have pilot hole along this guiding pole socket axial line, be set with spring and guide post in this pilot hole from the bottom up successively, when described spring was in free state, the guide post upper end reached outside the described guiding pole socket; The top of described guide-track groove is provided with top board, and this top board central bottom is fixed with push rod, and this push rod and guide post are on the same axial line.
The piston rod part of waiting to tear open engine placed the upper end of guiding pole socket and the guide post of guiding pole socket is inserted in the piston and with the piston pin lower surface and connect.Handle jack and make on the guiding pole socket and move, suitably adjust position of piston and be inserted into piston and connect with the piston pin upper surface until the push rod that is positioned at piston top.Continue to handle jack piston moved on continuing, this moment push rod will promote piston pin move down and drive guide post compress spring move down until piston pin is released piston and the pilot hole of the guide post seat of entering in.The application point of the power of jack is identical in said process, and simultaneously piston moves and guide post and push rod have all played in the positioning action of motion process to piston and piston pin all the time in vertical direction, and piston pin is on the vertical direction all the time.Therefore piston pin in the process that is pushed out the direction of stressed big or small basis equalization, especially power be in a straight line all the time, promptly consistent with the axial line of piston pin.The smooth-going taking-up that has guaranteed piston pin can't damage piston pin.
The end that described push rod and guide post and piston pin to be torn open connect all forms step surface, and the larger diameter end of this step surface is identical with the end face external diameter of waiting to tear open piston pin, and smaller diameter end waits to tear open the little 0.5-1MM of piston pin hole diameter than described.
Adopt said structure that piston and piston pin have been played spacing effect in the horizontal direction, further guaranteed the stability of piston and piston pin position in unloading process, the skew of piston and piston pin in avoiding dismantling.
The top of described guiding pole socket also is provided with a pair of supporting pin, and this supporting pin is positioned at the both sides of described guide post.
Beneficial effect: this tool for dissembling piston pins of electric generator is practical and convenient, can under situation own that do not damage and piston piston pin be taken out smoothly by the piston pin that assembling is not in place.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is that use the present invention dismantles the structural representation in the piston pin process;
Fig. 3 is the vertical view of middle guide groove of the present invention and gripper shoe annexation.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples:
Embodiment, as Fig. 1, shown in 2: a kind of tool for dissembling piston pins of electric generator, it comprises base 1, gripper shoe 3, jack 4, on described base 1, vertically be fixed with a pair of guide-track groove that is parallel to each other 2, described gripper shoe 3 two ends are inserted in the guide-track groove 2 that be arranged in parallel and can move up and down along described guide-track groove 2, be set with guiding pole socket 5 on the described gripper shoe 3, have pilot hole along these guiding pole socket 5 axial lines, be set with spring 8 and guide post 9 in this pilot hole from the bottom up successively, when described spring 8 was in free state, guide post 9 upper ends reached outside the described guiding pole socket 5; The top of described guide-track groove 2 is provided with top board 6, and these top board 6 central bottom are fixed with push rod 10, and this push rod 10 is on the same axial line with guide post 9.
Described push rod 10 and guide post 9 all forms step surface with the end that piston pin to be torn open connects, and the larger diameter end of this step surface is identical with the end face external diameter of waiting to tear open piston pin, and smaller diameter end waits to tear open the little 0.5-1MM of piston pin hole diameter than described.The top of described guiding pole socket 5 also is provided with a pair of supporting pin 7, and this supporting pin 7 is positioned at the both sides of described guide post 9.
The using method of this frock:
