Abstract
The utility model discloses a gauge for measuring the lower limit of a cylinder head valve, comprising a positioning core shaft, wherein the upper part of the positioning core shaft is a circular disc while the lower part is a guide rod; the outer diameter of the circular disc has the same gauge size with a valve line; and the guide rod is matched with a valve guide. While detecting the lower limit of a valve, the gauge is relatively convenient and reliable and high in accuracy; meanwhile, the manufacturing cost is low.
Description
Technical field
The utility model relates generally to and is used for cylinder cover for diesel engine, detects the measurement mechanism of valve lower limit after the valve line processing.
Background technology
After the processing of cylinder cover of diesel valve line; It is relatively stricter that the valve line gauge is put the cylinder junction surface required distance; The precision of valve lower limit can have influence on engine in work, valve probably can and piston between distance too small, the phenomenon of produce interfering; The size that how to guarantee and detect gauge size point to big face is to have great significance to quality and the performance of cylinder head product, and we have invented the valve lower limit and have measured cubing in order to measurement for this reason.
The utility model content
The utility model purpose is exactly for a kind of measurement cubing device of valve lower limit amount is provided, its detect more convenient in limited time, reliable under valve, accuracy is high, manufacturing cost is not high yet simultaneously.
The utility model is realized through following technical scheme:
The head valve lower limit is measured cubing, includes positioning core axle, and the top of positioning core axle is disk, and the bottom is a guide pole, and the external diameter of disk is identical with the gauge size of valve valve line, and guide pole matches with valve guide bushing.
The right alignment of said guide pole and disk requires in 0.005mm.
The upper end of described disk has screwed togather bolt.
In the middle of cubing, is furnished with bolt; So that cubing is taken from cylinder cap easily; The utility model holds up cylinder head when carrying out depth survey with three thimbles; Cylinder junction surface upwards in the guide pole insertion valve guide bushing with cubing, is measured the end face distance of cylinder junction surface to cubing with electronic digital indicator.
The disk external diameter of the utility model requires identical with measured gauge external diameter, and permissible error is at 0.01 mm, and the right alignment of guide pole and cylinder requires at 0.005mm, and the verticality of end face and guide pole requires at 0.005mm.Sounding rod all need adopt to grind with positioning core axle and standard gauge block and cooperate.
The utility model has the advantages that:
The utility model is convenient in limited time, reliable the measurement of gas student, accuracy is high, and manufacturing cost is not high simultaneously, has simple in structurely, easy to operate, is prone to the advantage of processing and manufacturing, and suitable medium-sized and small enterprises are used for controlling the product quality of valve lower limit.
Description of drawings
Fig. 1 is the instrumentation plan of the utility model.
Embodiment
Referring to accompanying drawing, the head valve lower limit is measured cubing, includes positioning core axle 1; The top of positioning core axle 1 is disk 2; The upper end of disk has screwed togather bolt 5, and the bottom is a guide pole 3, and the external diameter of disk is identical with the gauge size of valve valve line; Guide pole matches with 3 valve guide bushings 4, and the right alignment of guide pole and disk requires in 0.005mm.
