Description
Technical field
The utility model relates to the cylinder jacket measuring technique, especially the appliance special for detecting that the inclination angle of cylinder jacket supporting shoulder lower surface is measured.
Background technology
Supporting shoulder lower surface is the significant points of cylinder jacket part, it is the end face of cylinder jacket and engine body hole axial location, requirement on machining accuracy to it is very high, at present, in order to prevent cylinder jacket supporting shoulder breakage problem, increasing domestic main engine plants, particularly a lot of external famous engine company, optimized the design of cylinder jacket, the requirement that the lower surface has increased the inclination angle is takeed in supporting, different company has proposed different requirements, this angle is general require be 0 °～0 ° 15 ' or 0 ° 10 '～0 ° 25 ' or 0 °～0 ° 30 ' etc., for so little, the angle requirement that tolerance is so strict again, how to measure is a technical barrier.
The utility model content
The purpose of this utility model provides a kind of appliance special for detecting that the inclination angle of cylinder jacket supporting shoulder lower surface is measured.
For achieving the above object, the utility model adopts following technical scheme: a kind of appliance special for detecting that is used for detecting support shoulder inclination angle, lower surface, comprise base, be provided with dial test indicator and micrometer caliper on the base from left to right successively in the same way, micrometer caliper comprises telescopic sounding rod, fixed cover, the fixed sleeving that has scale, microdrum and knob, and sounding rod promotes dial test indicator.
Between dial test indicator and sounding rod, be provided with slide block assembly, slide block assembly comprise be arranged in parallel and and dial test indicator, sounding rod in the same way two baffle plates and the slide block between two baffle plates, the slide block right-hand member is provided with the round steel ball, the right side of round steel ball is provided with and returns baffle plate between two baffle plates, return the corresponding sounding rod of baffle plate and be provided with and stretch out the hole, sounding rod inserts and stretches out the hole and contact with the round steel ball; Dial test indicator is fixedlyed connected with slide block.
The fixed cover of micrometer caliper is inserted in the differential seat that has through hole, and through-hole diameter and fixed cover are suitable, and the differential seat is fixedly arranged on the base.
Described slide block upside is installed with column, and column is provided with vertical chute, also comprises the tong-test ammeter piece, and tong-test ammeter piece one end is provided with the projection that is fitted into chute, and level is equipped with bolt in the projection, and the bolt end face contacts with the chute bottom surface; The tong-test ammeter piece other end extends to the slide block left end outside and dial test indicator is fixedly arranged on tong-test ammeter piece left side.
The corresponding slider bottom of base is provided with groove, and slider bottom inserts in the groove.
Also comprise and be positioned at the cover plate that returns the baffle plate upside and be fixedly arranged on baffle plate.
During use, the cylinder jacket that will need earlier to detect is fixedly arranged on the base, because dial test indicator is fixedly arranged on the tong-test ammeter piece, tong-test ammeter piece projection can move up and down along the column chute, so dial test indicator also can move up and down and support the adaptive position of shoulder height degree thereupon, and the chaining pin of dial test indicator is positioned at and supports on the shoulder end face, tight a bolt then, at this moment the tong-test ammeter piece is also fixedlyed connected with slide block with column with dial test indicator, because the fixed cover of micrometer caliper is located in the differential seat, and micrometer caliper has the fixed sleeving external diameter of scale greater than the fixed cover external diameter, turn and can not be moved to the left so micrometer caliper has the outer ring of scale, not the time spent, also micrometer caliper can be extracted out from the right side.Rotate micrometer caliper and release sounding rod, sounding rod passes the hole of returning on the baffle plate of stretching out, promote round steel ball and slide block, slide block is moved to the left, tong-test ammeter piece and dial test indicator also move to left thereupon, then the chaining pin of dial test indicator just on cylinder jacket supporting shoulder lower surface straight line move, the difference in height of supporting shoulder lower surface just is reflected in the pointer rotation of dial test indicator, draw the numerical value that moves to left by micrometer caliper again, just can calculate cylinder jacket and support shoulder inclination angle, lower surface.Two baffle plates and base inner groovy all play the effect of guiding to slide block, return baffle plate and can limit the slide block right end position.In the practical operation, can make supporting shoulder inclination angle, lower surface-difference in height table of comparisons, in this table, the numerical value that rotates according to the dial test indicator indicator is the numerical value that difference in height can inquire corresponding supporting shoulder inclination angle, lower surface easily, perhaps according to question blank, work out dial test indicator indicator rotation value scope interval of acceptance, as long as dial test indicator indicator rotation value is in interval of acceptance, supporting shoulder inclination angle, lower surface is exactly qualified so, but note the direction that the dial test indicator indicator rotates, because when this inclination angle is actual when being negative value, the dial test indicator indicator can rotate in the opposite direction.It is accurate to detect supporting shoulder inclination angle, lower surface quite stable with this appliance special for detecting, is simple and easy to usefulness, and easy to operate, detection efficiency is higher, and the cubing failure rate is low, satisfies the qualified requirement of measuring system MSA fully.
