The present invention is simple in structure, compact, and measuring accuracy is high, and is simple to operate, can the tested grade width change amount of opening of fast detecting, and can make checkout equipment can check more high-grade size.
Description of drawings
Fig. 1 is one-piece construction schematic diagram of the present invention.
Fig. 2 is one-piece construction profile schematic diagram of the present invention.
Embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in Figure 1: the present invention mainly is comprised of flange 1, push rod 2, regulator 3, screw 4, the first measuring staff 5, elastomer block 6, the second measuring staff 7, limited block 8, screw 9, screw 10 etc.
Width measurement mechanism, it comprises the mounting groove 13 that regulator 3 two sides are offered, interior with two elastomer block 6 of screw 4 connections at mounting groove 13, offer elastic deformation zone 11 and bonding survey ball 14 in elastomer block 6, and offer mounting hole 12 on the elastomer block 6, the first measuring staff 5 is installed respectively and the second measuring staff 7, the first measuring staffs 5 other ends are provided with oblique groove 16 mounting hole 12 is interior, and the second measuring staff 7 other ends are provided with inclined-plane 15.Inclined-plane 15 and oblique groove 16 are spacing mandrils 2, the bottom of push rod 2 is spherical 17, the top of push rod 2 has the center hole 18 that ground, push rod 2 stretches out regulator 3 in flange 1, be provided with spacing preiection 19 in push rod 2 parts that are positioned at flange 1 the inside, regulator 3 is fastenedly connected with flange 1 usefulness screw 9.Use screw 10 fastening two limited blocks 8 in regulator 3 both sides.
The contact workpiece of described elastomer block 6 partly is spherical surface body.Described spacing preiection is circular protruding 19 of push rod 2 outer walls setting.There is the certain proportion relation position that offers elastic deformation zone 11, bonding survey ball 14 and mounting hole 12 on the described elastomer block 6.Offering elastic deformation zone 11 on the described elastomer block 6 is in order to make elastomer block 6 one ends bonding survey ball 14 reaches measurement around this area rotation purpose, to be equivalent to the swivel point of lever.The first measuring staff 5 other ends are provided with angle that oblique groove 16 and the second measuring staff 7 other ends are provided with inclined-plane 15 need be combined with the proportionate relationship that elastomer block 6 position of mounting hole and bonding are surveyed ball position that to reach last ratio out be the relation of 1:1.Described spacing preiection 19 has certain distance to guarantee to bond with flange 1 hole end surface to survey the stroke of ball.Described regulator 3 both sides are connected with two limited blocks 8 and limit the initial position that bonding is surveyed ball 14.
During installation, the first step is installed to the first measuring staff 5, the second measuring staff 7 on the elastomer block 6 first; Be installed to again in the regulator 3; Second step is fastened on limited block 8 on the regulator 3; The 3rd step installed regulator and flange 1 fixing; The 4th step was put into regulator 3 the insides with push rod 2, contacted with the first measuring staff 5, the second measuring staff 7.
The present invention is when making, and the width that limited block 8 combines is slightly larger than detected width, and elastic body 6 touches the tested grade wall of opening, and outwards upheld by acting force, thereby measuring staff is also outwards upheld.Push rod 2 is moved down by the measuring staff effect, thereby reaches the purpose of transmitting the wide variety amount.
As shown in Figure 1, elastomer block 6 is clearance fit with regulator 3, and the error that elastomer block 6 is produced in rotation process reaches less; The first measuring staff 5, the second measuring staff 7 are interference fit with elastomer block 6; The first measuring staff 5, the second measuring staff 7 pass to push rod 2 to the displacement of elastomer block 6; Elastomer block 6 itself provides the elastic force of an inside contraction always owing to elastic deformation, be that measuring point contacts the workpiece measured surface all the time.
Principle of work of the present invention and the course of work are as follows:
Elastomer block 6 relatively and limited block 8 certain bulge quantity is arranged, snapping into the tested grade rear elastomer block 6 of opening upholds outward, make the first measuring staff 5, the second measuring staff 7 also and then outwards mobile, impel push rod 2 to move down, finally can make the detecting instrument (can be scale or sensor) that is connected to the feeler gauge head detect out grade width change amount and demonstrate numerical value.
