The utility model content
The technical matters that the utility model will solve provide a kind of simple in structure, easy to operate, according to the measuring basis principle consistent with machining benchmark to the locating bar being valve seat that the valve seat of benchmark processing the carries out glitch detection cubing of beating.
For solving the problems of the technologies described above; The utility model comprises locating sleeve and rotary sleeve; Locating sleeve is sleeved on the top of the locating bar used of processing valve seat; Locating sleeve is fixed on the locating bar through dog screw, and rotary sleeve does not have axially to jump and do not have radial displacement ground turning set and is contained on the locating sleeve, and lever indicator is installed on the rotary sleeve.
Bottom-up lower floor's boss and the upper strata boss of being equipped with respectively of the periphery of said locating sleeve; Rotary sleeve is located on lower floor's boss; The upper strata boss is provided with the stop collar that is sleeved on the locating sleeve; The locating sleeve top is provided with the stop nut on the end face that is pressed against stop collar, the bottom surface clearance fit of the end face of rotary sleeve and stop collar.
Have table bar hole on the outer wall of said rotary sleeve, the table bar is fitted with the table bar in the hole, and the outer end of table bar is equipped with lever indicator.
But be provided with the clip of banding table bar in the said table bar hole, table bar hole sidewall has tapped through hole, and the table bar trip bolt that can hold out against clip is housed in the tapped through hole.
The beneficial effect of the utility model is: locating sleeve can be sleeved on the top of locating bar and be fixed on the locating bar with dog screw; The pointer of lever indicator is leaned against on the valve seat; Rotary sleeve rotated a circle to accomplish the measurement that valve seat is beated; Principle simple to operation, that the coincidence measurement benchmark is consistent with machining benchmark, measurement result are accurately, reliably; The periphery of locating sleeve sets layer boss and the upper strata boss is used for installing rotary sleeve and stop collar; Wherein stop collar can more effectively prevent axially jumping of rotary sleeve; In addition, the table top of upper strata boss is a little more than the end face of rotary sleeve, and stop nut holds out against stop collar on the boss of upper strata; Prevent that stop collar from following rotary sleeve and rotating, make the position-limiting action of stop collar more reliable; Lever indicator is packed on the rotary sleeve through the table bar and uses table bar trip bolt fastening, and the table bar has certain telescopic adjustment amount in table bar hole, measures simpler, more practical.The utility model is simple in structure, easy to operate, has solved the glitch detection problem of the valve seat that with the locating bar is benchmark processing, and the principle that the coincidence measurement benchmark is consistent with machining benchmark is measured accurate, reliable.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is along the cut-open view of B-B direction among Fig. 1.
Embodiment
With reference to accompanying drawing; The utility model comprises locating sleeve 4 and rotary sleeve 6; Locating sleeve 4 is sleeved on the top of the locating bar 3 of processing valve seat 2 usefulness; Locating sleeve 4 is fixed on the locating bar 3 through dog screw 5, and rotary sleeve 6 nothings axially jump and do not have radial displacement ground turning set and are contained on the locating sleeve 4, and lever indicator 10 is installed on the rotary sleeve 6.As shown in fig. 1; Locating bar 3 is plugged in the cylinder cap 1 in order to processing valve seat 2, processes after the valve seat 2, and locating bar 3 need not take out; Put locating sleeve 4 on locating bar 3 tops; Have in the middle of the locating sleeve 4 that size with locating bar 3 adapts internal cavity, this internal cavity and locating bar 3 assert basically that with the clearance fit of 0.003-0.006mm both are the cooperation of no gap.Dog screw 5 holds out against locating bar 3, make locating sleeve 4 locating bar 3 axially with radially all do not produce displacement.Rotary sleeve 6 turning sets are contained on the locating sleeve 4; Match grinding gap between the outer wall of the inwall of rotary sleeve 6 and locating sleeve 4 is 0.003-0.006mm; Basically think not have the gap and cooperate, around locating sleeve 4 rotations, accomplish measurement valve seat 2 jitter values but this gap can guarantee rotary sleeve 6 no radial displacement ground.Lever indicator 10 is a pointer contact table of measuring jitter values in the prior art.
