Abstract
The invention relates to a tool structure for measuring the length of a ring groove of a plunger piston part. The tool structure comprises a chassis, wherein a support is fixedly connected with the chassis, a positioning mandrel penetrates the support and is located in the support, respectively sleeved by a first lining and a second lining and located between the first lining and the second lining, and a first spring is further arranged on the positioning mandrel. Steel balls are symmetrically arranged inside the positioning mandrel, and a second spring is connected between two steel balls. The tool structure is simple in structure and quick and convenient to measure, embedding connection of the ring groove of an inner ring of a plunger sleeve is achieved by utilizing the steel balls symmetrically arranged in the positioning mandrel, positioning is quick and convenient, a measurement standard of the plunger sleeve is effectively achieved by utilizing a blocking plate, measurement of a distance between the ring groove of the plunger sleeve and the end face is achieved, the time and labor are saved, the measurement efficiency is greatly improved, and the enterprise cost is saved.
Description
Technical field
The present invention relates to frock, relate in particular to a kind of tool structure for the linear measure longimetry of plunger member ring recess.
Background technology
Plunger matching parts is formed by plunger and plunger bushing precision-fit, delivery valve matching parts (being made up of delivery valve and delivery valve seat) is equipped with in its top, plunger can be divided into A type, Type B, K type, AD type, P type etc. by its applicable injection pump difference, to meet the demand of different diesel engines.At present, the inner ring of existing plunger bushing generally needs to process one ring recess, for the dimensional requirement needs that meet product drawing, the distance between ring recess and plunger bushing end face is measured, existing frock cannot meet the measurement of above-mentioned size, therefore in the urgent need to designing a kind of new tool structure.
Summary of the invention
The applicant, for above-mentioned existing issue, is studied improvement, and a kind of tool structure for the linear measure longimetry of plunger member ring recess is provided, effectively realize the ring recess of plunger bushing to the Quick Measurement of end face distance, make measure batch become possibility, improved work efficiency, time saving and energy saving.
The technical solution adopted in the present invention is as follows:
A kind of tool structure for the linear measure longimetry of plunger member ring recess, comprise chassis, support and described chassis are affixed, positioning core axle through-going device is in described support, be positioned at described support, on described positioning core axle, be set with the first lining and the second lining, between the first lining and the second lining, returning apparatus the first spring on described positioning core axle; Be positioned at the symmetrical mounting steel ball of positioning core axle, between two steel balls, connect the second spring.
Its further technical scheme is:
On described positioning core axle, have the through hole for installing interlocking steel ball, the two ends of described through hole arrange closing in, at least in one end of through hole, in the interior installation sleeve that is also socketed of described positioning core axle;
The closing in diameter of described through hole is less than the diameter of steel ball;
Affixed baffle plate also on described chassis, on baffle plate, symmetry extends to form boss.
Affixed clamping plate also on described chassis, the locator sub of device dial gauge in described clamping plate.
Beneficial effect of the present invention is as follows:
The present invention is simple in structure, it is quick and convenient to measure, the steel ball that utilization is arranged symmetrically in positioning core axle has been realized the interlocking to plunger bushing inner ring ring recess, locate quick and convenient, utilize baffle plate effectively to realize the benchmark that plunger bushing is measured, realize the range observation between plunger bushing ring recess in enormous quantities and end face, time saving and energy saving, greatly improve measurement efficiency, save enterprise cost.
Accompanying drawing explanation
Fig. 1 is front view of the present invention.
Fig. 2 is sectional structure schematic diagram of the present invention.
Wherein: 1, dial gauge; 2, clamping plate; 3, locator sub; 4, support; 5, the first lining; 6, the first spring; 7, the second lining; 8, plunger bushing; 801, ring recess; 9, the second spring; 10, steel ball; 101, installation sleeve; 11, chassis; 12, baffle plate; 1201, boss; 13, positioning core axle; 1301, through hole.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1 and Figure 2, a kind of tool structure for the linear measure longimetry of plunger member ring recess, comprise chassis 11, support 4 and chassis 11 be not by register pin and securing member affixed (register pin and securing member mark in the drawings), positioning core axle 13 through-going devices, in support 4, are positioned at support 4, are set with the first lining 5 and the second lining 7 on described positioning core axle 13, between the first lining 5 and the second lining 7, returning apparatus the first spring 6 on positioning core axle 13; Be positioned between symmetrical mounting steel ball 10, two steel balls 10 of positioning core axle 13 and connect the second spring 9.On positioning core axle 13, have the through hole 1301 for installing interlocking steel ball 10, the two ends of through hole 1301 arrange closing in, at least in one end of through hole 1301, in the interior installation sleeve 101 that is also socketed of positioning core axle 13.The closing in diameter of through hole 1301 is less than the diameter of steel ball 10.Affixed baffle plate 12 also on chassis 11, on baffle plate 12, symmetry extends to form boss 1201.Affixed clamping plate 2 also on chassis 11, the locator sub 3 of the interior device dial gauge 1 of described clamping plate 2.
Specific works process of the present invention is as follows;
As Fig. 1, shown in Fig. 2, first the internal diameter of the plunger bushing 8 that processes ring recess 801 is matched with positioning core axle 13, and make the outward extending two end boss places of plunger bushing 8 and boss 1201 butts, find thus measurement datum, then in engagement process, the stretching at plunger bushing 8 internal diameters by positioning core axle 13, until steel ball 10 contacts with the ring recess 801 of plunger bushing 8, now two steel balls 10 are stretched out by the elastic force of the second spring 9, because the two ends of the through hole 1301 of positioning core axle 13 arrange closing in, therefore steel ball 10 to stretch out area less, but it stretches out area and embeds in ring recess 801, because the other end of positioning core axle 13 and the locator sub 3 of dial gauge 1 connect, therefore now by checking that the distance that the reading of dial gauge can be found between ring recess 801 and plunger bushing end face measures.
More than describing is explanation of the invention, is not the restriction to invention, and limited range of the present invention, referring to claim, within protection scope of the present invention, can be done any type of modification.
