Abstract
A kind of new piston positioning fixture, belongs to clamp art.Piston can be positioned for it and clamping, and effect is good.The floor level is set, riser and the benchmark panel is vertically arranged, riser bottom surface is fixedly connected with plate upper surface left end, the benchmark panel bottom surface is fixedly connected with plate upper surface right-hand member, and the sharp side cylinder is horizontally disposed with, and sharp side cylinder left side is fixedly connected with riser right flank, through hole is offered on the benchmark panel, the plunger passes through benchmark panel by the through hole of benchmark panel, and on plunger, the plunger left side is fixedly connected the spring housing with rubber blanket.The utility model is designed reasonably, accurate positioning is easy to use, simple in construction.Rubber blanket can also reduce the surface abrasion to piston, compensator or trimmer pressure.Measurement to piston provides accurate positioning, avoids piston and measurement data often occurs and forbidden, produces the phenomenon of error, have higher application value.
Description
Technical field
The utility model belongs to clamp art, more particularly to a kind of piston positioning fixture.
Background technology
At present in 1.2TGD1 engine tests, it is insufficient engine combustion often occur, it is necessary to right phenomena such as oil leak
The piston of engine carries out accident analysis detection, and the size at piston ring groove position is most important to the performance impact of engine.By
Annular groove groove width and piston-shaped influence, originally detecting piston does not have positioning fixture, and piston easily produces movement when measuring, makes survey
It is inaccurate to measure result, comes for breakdown in the motor analytic band difficult.
The content of the invention
The purpose of this utility model is to provide a kind of new piston positioning fixture, it piston can be carried out positioning and
Clamping, effect are good.
Technical solution adopted in the utility model is：A kind of new piston positioning fixture, including riser, sharp side circle
Post, plunger, spring, rubber blanket, benchmark panel and bottom plate；The floor level is set, and riser and the benchmark panel is vertical
Set, riser bottom surface is fixedly connected with plate upper surface left end, and the benchmark panel bottom surface is fixed with plate upper surface right-hand member to be connected
Connect, the sharp side cylinder is horizontally disposed with, and sharp side cylinder left side is fixedly connected with riser right flank, is opened up on the benchmark panel
There is through hole, the plunger passes through benchmark panel by the through hole of benchmark panel, and for the spring housing on plunger, the plunger is left
End face is fixedly connected with rubber blanket.
The beneficial effects of the utility model are：
The utility model is designed reasonably, accurate positioning is easy to use, simple in construction.Rubber blanket can be also reduced to piston
Surface abrasion, compensator or trimmer pressure.Measurement to piston provides accurate positioning, avoids piston and measurement data often occurs not
Standard, the phenomenon of error is produced, there is higher application value.The utility model is suitable for 1.2TGD1 engine pistons and more
Change part point side cylinder can also provide reliable guarantee to the measurement of the ring groove position of any model engine piston for detection.

Embodiment
As shown in figure 1, a kind of new piston positioning fixture, including riser 1, sharp side cylinder 2, plunger 3, spring 4, rubber
Pad 5, benchmark panel 7 and bottom plate 8；The bottom plate 8 is horizontally disposed, and the riser 1 and benchmark panel 7 are vertically arranged, the bottom of riser 1
Face is fixedly connected with the upper surface left end of bottom plate 8, and the bottom surface of benchmark panel 7 is fixedly connected with the upper surface right-hand member of bottom plate 8, the point
Side cylinder 2 is horizontally disposed, and the sharp left side of side cylinder 2 is fixedly connected with the right flank of riser 1, is offered on the benchmark panel 7 logical
Hole, the plunger 3 pass through benchmark panel 7 by the through hole of benchmark panel 7, and the spring 4 is sleeved on plunger 3, the plunger 3
Left side is fixedly connected with rubber blanket 5.
The new piston positioning fixture also includes sleeve 6, and sleeve 6 is fixed between the plunger 3 and rubber blanket 5,
The sleeve 6 is sleeved on spring 4.
The thickness of the rubber blanket 5 is 1mm ~ 3mm.
The depth of parallelism of the benchmark panel 7 is 0.01mm.
The new piston positioning fixture also includes bearing 11, installation axle 10 and jackscrew 9；The sharp left end of side cylinder 2
Face offers circular groove, and the bearing 11 is fixedly installed in the circular groove of sharp side cylinder 2, and the bearing 11 fixes suit
In installation axle 10, the installation axle 10 is fixedly connected with the right flank of riser 1, and the riser 1 offers screwed hole, the sharp side
Cylinder 2 and riser 1 are fixed by jackscrew 9.Bearing 11 can rotate sharp side cylinder 2, be easy to measure.
It is sharp when the right-hand member of cylinder 2 is machined with sharp.
Method of work：Piston seam position is gently put on sharp side cylinder 2, rotary-piston is correctly matched somebody with somebody with sharp side cylinder 2
Close, sharp side cylinder 2 is fitted close with piston seam, to prevent coming off for piston, compression spring 4, rubber blanket 5 is slowly connect
Piston is touched, piston is withstood using the strength of spring 4, realizes being properly positioned for piston.Again by the overall vertical rotation of the utility model
90 °, it is placed in universal tool microscope instrument, piston ring groove position is measured.
The effect of rubber blanket 5 is to ensure not damage the clamping face of piston.
Preferred embodiment of the present utility model is the foregoing is only, is not limited to the utility model, for this
