Said spacing preiection and flange hole end face have certain interval to guarantee the gauge head stroke; Said rule body both sides are connected with two limited blocks and limit the initial position of surveying ball.
The bottom of said push rod is a spherical, and the top of push rod has the center hole that ground.
The contact workpiece of said elastomer block partly is a spherical surface body.The circular convexity that said spacing preiection is provided with for the push rod outer wall.
There is the certain proportion relation position that offers elastic deformation zone, bonding survey ball and mounting hole on the said elastomer block.
The said first measuring staff other end has oblique groove and the bevelled angle of the second measuring staff other end to merge the relation that the ratio that reaches to come out at last is 1:1 with the proportionate relationship of elastomer block position of mounting hole and bonding survey ball position.
The utility model is simple in structure, compact, and measuring accuracy is high, and is simple to operate, can the tested variable quantity of opening grade width of fast detecting, and can make checkout equipment can check more high-grade size.

Fig. 1 is the one-piece construction synoptic diagram of the utility model.
Fig. 2 is the one-piece construction profile synoptic diagram of the utility model.
Embodiment
Below in conjunction with concrete accompanying drawing and embodiment the utility model is described further.
As shown in Figure 1: the utility model mainly is made up of flange 1, push rod 2, rule body 3, screw 4, first measuring staff 5, elastomer block 6, second measuring staff 7, limited block 8, screw 9, screw 10 etc.
Width measure mechanism; It comprises the mounting groove 13 that rule body 3 two sides are offered, and in mounting groove 13, connects two elastomer block 6 with screw 4, on elastomer block 6, offers elastic deformation zone 11 and bonding and surveys ball 14; And mounting holes 12 on the elastomer block 6; First measuring staff 5 is installed respectively in mounting hole 12 and second measuring staff, 7, the first measuring staffs, 5 other ends are provided with oblique groove 16, and second measuring staff, 7 other ends are provided with inclined-plane 15.Inclined-plane 15 is to be used for spacing push rod 2 with oblique groove 16; The bottom of push rod 2 is a spherical 17; The top of push rod 2 has the center hole 18 that ground; Push rod 2 stretches out rule body 3 in flange 1, is provided with spacing preiection 19 in push rod 2 parts that are positioned at flange 1 the inside, and rule body 3 is fastenedly connected with flange 1 usefulness screw 9.Advising body 3 both sides with screw 10 fastening two limited blocks 8.
The contact workpiece of said elastomer block 6 partly is a spherical surface body.Said 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 said elastomer block 6.Offering elastic deformation zone 11 on the said elastomer block 6 is to rotate the purpose that reaches measurement in order to make elastomer block 6 one ends survey ball 14 around this zone, is equivalent to the swivel point of lever.First measuring staff, 5 other ends are provided with the angle that oblique groove 16 and second measuring staff, 7 other ends are provided with inclined-plane 15 need merge the relation that the ratio that reaches to come out at last is 1:1 with the proportionate relationship that elastomer block 6 position of mounting hole and bonding are surveyed ball position.Said spacing preiection 19 has certain distance to guarantee the gauge head stroke with flange 1 hole end surface.Said rule body 3 both sides are connected with two limited blocks 8 and limit the initial position of surveying ball 14.
During installation, the first step is installed to first measuring staff 5, second measuring staff 7 on the elastomer block 6 earlier; Be installed to again in the rule body 3; Second step was fastened on limited block 8 on the rule body 3; The 3rd step will advise body and flange 1 installs and fixes; The 4th step was put into rule body 3 the insides with push rod 2, contacted with first measuring staff 5, second measuring staff 7.
The utility model is when making, and the width that limited block 8 combines is slightly larger than width to be detected, and elastic body 6 touches the seized 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 change width amount.
Shown in accompanying drawing 1, elastomer block 6 is clearance fit with rule body 3, and the error that elastomer block 6 is produced in rotation process reaches less; First measuring staff 5, second measuring staff 7 are interference fit with elastomer block 6; First measuring staff 5, second measuring staff 7 pass to push rod 2 to the displacement of elastomer block 6; Elastomer block 6 is own because elastic deformation provides an elastic force of inwardly shrinking always, is measuring point contact workpiece measured surface all the time.
The principle of work and the course of work of the utility model are following:
Elastomer block 6 relatively and limited block 8 certain protrusion amount is arranged; Snapping into the tested grade back elastomer block 6 of opening upholds outward; First measuring staff 5, second measuring staff 7 are also and then outwards moved; Impel push rod 2 to move down, finally can make the detecting instrument (can be scale or sensor etc.) that is connected to the feeler gauge head detect out the variable quantity of grade width and demonstrate numerical value.
