Description
Technical field
The present invention relates to a kind of fine measuring instrument for internal combustion engine piston spigot, belong to the machine-building fields of measurement.
Background technology
In piston machining process process in enormous quantities for guaranteeing piston each size and geometric accuracy; set first basic circle of processing; come other how much parts of machining piston with this origin reference location again, this basic circle claims the piston seam in technical jargon, i.e. diameter of phi in Fig. 1 piston cut-open view.
Circulation seam measuring instrument at home and abroad is various now, but the style structure substantially roughly the same, a common feature is arranged, namely two dynamometry are that pressure or pulling force by spring provides, measure its precision at a surveying instrument and can guarantee the measuring technique requirement fully, if with two the same piston seam of apparatus measures diameters, the value of measurement will change to some extent, its reason is the difference of the spring force of two instruments, so the dynamometry that produces is also different.Because spring has fatigue limit, can produce force variation after use a period of time, this just makes measuring instrument have the factors of instability, and therefore the operator needs frequent check and correction instrument in batch production, and this just brings certain impact to production efficiency.
Summary of the invention
The object of the invention is exactly the deficiency that solves in the above technology, and a kind of invariable and every seam precision measuring instrument that dynamometry equates is provided.
A kind of fine measuring instrument for internal combustion engine piston spigot, comprise the seam tire, establish respectively slide rail in seam tire both sides, two slide rails point-blank and be respectively equipped with a slide block on the slide rail, establish measuring head base on the slide block, measuring staff and measuring head are housed on the measuring head base of one of them slide block, clock gauge and measuring head are housed on the measuring head base of another slide block, two slide blocks are connected with the same gravity system that drives its slip by gentle rope respectively, and slide rail, seam tire are all on platform.
Described gravity system comprises weight, the middle pulley frame is housed on the weight, and the middle pulley frame links to each other with middle pulley by pulley spindle, and middle pulley is travelling block, hang on the gentle rope, the two ends of gentle rope are walked around respectively turnover pulley (fixed pulley) and are tied up on the measuring head base of two slide blocks.
Described turnover pulley is fixed on the platform by turnover pulley yoke and turnover pulley spindle.
Described measuring head base is connected with limited block, and limited block links to each other with the stop screw seat by stop screw, and the stop screw seat is fixed on the platform.
Described measuring staff one end is fixed on measuring head base, and the other end passes the seam tire and contacts with the gauge head of clock gauge.
Described platform has four supporting legs to support.
The present invention arranges slide rail and use same Action of Gravity Field, and dynamometry is balanced, and the dynamometry between instrument is consistent, and it is a kind of instrument that dynamometry changes never, and its advantage is far longer than the original seam precision measuring instrument of making dynamometry of spring.Need not repeatedly to adjust or repair spring force, obviously also will further increase work efficiency, again because of eternal constant of dynamometry, so also just guarantee the stability of product quality.

Embodiment
A kind of fine measuring instrument for internal combustion engine piston spigot, comprise seam tire 12, establish respectively slide rail 4 in seam tire 12 both sides, two slide rails 4 point-blank and be respectively equipped with a slide block 3 on the slide rail 4, establish measuring head base 9,14 on the slide block 3, measuring staff 10 and measuring head 13 are housed on the measuring head base 9 of one of them slide block, clock gauge 23 and measuring head 13 are housed on the measuring head base 14 of another slide block, two slide blocks 3 are connected with the same gravity system that drives its slip by gentle rope 5 respectively, and slide rail 4, seam tire 12 are all on platform 2.
Described gravity system comprises weight 18, middle pulley frame 17 is housed on the weight 18, middle pulley frame 17 links to each other with middle pulley 15 by pulley spindle 16, middle pulley 15 is travelling block, hang on the gentle rope 5, the two ends of gentle rope 5 are walked around respectively turnover pulley 7 (fixed pulley) and are tied up on the measuring head base 9,14 of two slide blocks.
Described turnover pulley 7 is fixed on the platform 2 by turnover pulley yoke 6 and turnover pulley spindle 8.
Described measuring head base 9,14 is connected with limited block 21, and limited block 21 links to each other with stop screw seat 20 by stop screw 19, and stop screw seat 20 is fixed on the platform 2.
Described measuring staff 10 1 ends are fixed on measuring head base 9, and the other end passes seam tire 12 and contacts with the gauge head of clock gauge 23.
Described fine measuring instrument for internal combustion engine piston spigot, the platform 2 that has four supporting legs 1 to support, the slide rail 4 of a line slideway is housed on the platform 2, the above has two symmetrical slide blocks 3 of placing, two slide block 3 is installed in respectively the left and right sides of seam tire 12, two slide blocks 3 are equipped with respectively left measuring head base 9 and right measuring head base 14, measuring staff 10 is housed above its left measuring head base 9 and runs through seam tire 12, one end contacts with the gauge head of clock gauge 23, clock gauge 23 is contained on the gauge stand 22, gauge stand 22 is contained in above the right measuring head base 14, at two measuring head bases 9, measuring head 13 also is housed respectively on 14, such two slide blocks 3 can drive measuring head base 9 when doing relative motion, 14 and measuring staff 10, clock gauge 23, measuring head 13 is done relatively or the reverse direction motion together, and clock gauge 23 just can be read the distance value that produces in 3 motions of two slide blocks like this.The power that two slide blocks 3 are done relative motion derives from weight 18, middle pulley frame 17 is housed on the weight 18, middle pulley frame 17 links to each other with middle pulley 15 by pulley spindle 16, its pulley is that freely falling body is placed on the gentle rope 5, the two ends of gentle rope 5 are walked around respectively turnover pulley 7 and are tied up on two measuring head bases 9 and 14, turnover pulley 7 is to be supported on the platform 2 by turnover pulley yoke 6 and turnover pulley spindle 8, the dynamometry of such two measuring heads 13 derives from a weight power jointly, two stop screw seats 20 also are housed on platform 2, each end that stop screw 19, two stop screws 19 respectively are housed on the stop screw seat 20 leans respectively on the limited block 21 that is assembled together with measuring head base 9 and 14.More than be basic building block and the basic structural relationships of piston seam precision measuring instrument.
This metering system is comparative measurement method, and first an internal diameter ring gauge size is leveled off to the standard component (omitting among the figure) of Φ be put on the seam tire 12 before measuring piston, then with clock gauge 23 and measuring staff 10 precompressed and make list index on null value.Remove the standard component ring gauge, put into again piston 11 and do 360 degree revolutions, so not only can measure the shape circularities that seam physical size value also can be measured seam simultaneously.
Because the dynamometry of two measuring heads 13 derives from a weight 18 jointly, and two power can complementary equate, because weight 18, middle pulley 15, middle pulley frame 17, middle pulley axle 16 are independent assemblies, can weighing after the assembling and can increase and decrease arbitrarily the quality of weight 18, so no matter multiple this grip assembly is, its dynamometry is to accomplish in full accordly, so just can guarantee consistance and the interchangeability of piston seam precision measuring instrument in measurement.
The spacing purpose of stop screw seat 20, stop screw 19, limited block 21 be allow two measuring heads 13 exceed surpass actual measurement seam diameter dimension, be convenient to Quick Measurement and prevent that excessive stroke from breaking clock gauge 23.
