The elastic piece mechanism can realize diameter differential measurement, pulsation measurement and multifunction, has good linearity, low error and high repeated accuracy, and can be connected and mounted with various baseboards via reserved thread holes, to improve application field and improve positioning accuracy, therefore, the detection devices can detect the sizes of higher level.

Description

Elastic block mechanism

Technical field

The utility model relates to a kind of elastic block mechanism, specifically is used to measure the difference transmission, and the correlating factor precision measure belongs to the inspection technology field of measuring.

Background technology

In prior art, to measure transmission mechanism and normally adopt lever, the rotation that lever is based on point of fixity reaches the effect of transmission.Generally precision is low for it, and linear poor, contact measurement is inaccurate, and repeatable accuracy is low.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned weak point, thereby a kind of elastic block mechanism is provided, and can realize the diameter variate, the measurement of beating, and linear good, error is little, and can improve bearing accuracy, can make the more high-grade size of checkout equipment check.

According to the technical scheme that the utility model provides, it mainly adopts movable block to be placed in the rule body, with pin movable block is connected with the rule body to be integral; Bearing Installation is at the two ends of pin, and bearing is pressed in the rule body mounting hole, and the bearing capping is installed on the end face of bearing; Pin and bearing are press-fitted to be connected by advising body packs in the movable block, and with tightening screw lock; Measuring staff and chuck be connected and fixed and and the latch segment clamping on movable block; Spring assembly is by being screwed into movable block on the rule body.

Described rule body is provided with threaded hole A and threaded hole B.

Described spring assembly is made up of spring and threaded joint.

The utility model the utility model is simple, compact and reasonable for structure; The position control of selling by the motion of measuring staff is converted to the motion of movable block, has reached the effect of alternative traditional lever, can improve precision, increases functions of use; Movable block separates making with the rule body, makes the measuring staff transfer turn to the movable block displacement; Owing on this elastomer block, can realize the diameter variate, the measurement of beating, realize multi-functional, and linear good, error is little, the repeatable accuracy height, can by its reserve threaded hole easily with various bedplate connections, can increase the occasion of using, and can improve bearing accuracy, make checkout equipment can check more high-grade size.

Embodiment

Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:

As shown in Figure 1, comprising: measuring staff 1, chuck 2, latch segment 3, bearing 4, pin 5, bearing capping 6, movable block 7, spring assembly 8, pin 9, rule body 10, bearing 11 and tighten screw 12 etc.

The utility model is placed in movable block 7 earlier in the rule body 10, with pin 5 movable block 7 and rule body 10 is linked together then.Bearing 4 is installed in the two ends of pin 5, simultaneously bearing 4 is pressed in the mounting hole that rule body 10 reserves, bearing capping 6 also is installed on the end face of bearing 4 subsequently, tightens screw 13 lockings after adjusting the position.It is good that pin 9 and bearing 11 are press-fitted connection in advance, packs into by rule body 10 and tighten screw 12 lockings after movable block 7 is adjusted the position.Again measuring staff 1 is connected and fixed with screw and chuck 2 by screw hole C, then with screw with latch segment 3 and the measuring staff 1 that has fixed, chuck 2 clampings on movable block 7.Spring assembly 8 is screwed into by the reservation threaded hole B on the rule body 10 and adjusts the position.Spring assembly 8 is made up of spring and threaded joint.Be provided with on the body 10 on rule and reserve threaded hole A, can by reserve threaded hole A easily with various bedplate connections.

The utility model measuring staff 1 mainly plays the contact measured workpiece.When making, connect rule body 10 and movable block 7, played good bearing accuracy and guide effect through bearing 4 with pin 5.Pin 9 has limited the rotation of movable block to pin 5 after screw 12 is fixing, and sells 9 and be press-fitted with bearing 11 and guaranteed alignment, and bearing 11 has played supporting pin 9 and movable block 7 plays good guide effect in moving.Well move linear precision through having played behind the two cover bearings.Spring assembly 8 provides the pressure of measuring staff contact measurement workpiece, and the return action of movable block 7.

The principle of work of the present utility model and the course of work:

The utility model contacts measured workpiece with measuring staff in work, when rotating or be mobile, workpiece caused the motion of measuring staff owing to error, measuring staff and movable block link together, and have so just driven the motion of movable block, transmit the purpose of measuring thereby reached.

Points for attention of the present utility model:

1, bar lubricating oil protection purpose.2, reduce friction force.3, make abrasion reduce to minimum, prevent corrosion phenomenon.
