Abstract
The invention relates to a gapless displacement transmission mechanism which mainly comprises an upper pressure plate, a lower pressure plate and a leaf spring. The upper pressure plate, the lower pressure plate and the leaf spring are connected with one another by screws, a limiting shaft is screwed into a fixing block, a copper bush is pressed into the fixing block, a fixing pressure plate and the leaf spring are mounted on the fixing block by screws, screws penetrate through a movable pressure plate so as to connect the leaf spring with a movable block, a spring device is screwed into the fixing block via the leaf spring and is positioned, a measuring block is fixed onto the movable block via the leaf spring by the aid of a set screw and is positioned, and a measuring bar is fixed onto the movable block by screws. The gapless displacement transmission mechanism has the advantages that the traditional lever can be replaced, the precision can be improved, and service functions are increased; gapless displacement of the measuring bar and the movable block is realized via the leaf spring; and multifunctional measurement for diameter differences, pulsation and the like can be realized by the gapless displacement transmission mechanism, the gapless displacement transmission mechanism is good in linearity and high in repeatability precision, and has few errors, and detection equipment can be used for detecting high-grade dimensions owing to the gapless displacement transmission mechanism.
Description
Technical field
The present invention relates to a kind of gapless displacement transmission mechanism, realize the non-size transmission that directly contacts between high-acruracy survey device and workpiece, belong to the inspection technology field of measuring.
Background technology
For making measuring element (for example electronic displacement sensor or clock gauge) produce unnecessary damage to its bump when avoiding tangential force and preventing the workpiece loading and unloading; Need between measuring element and workpiece, to set up a cover displacement transmission mechanism.In prior art, the displacement transmission mechanism normally adopts rolling bearing leverage or linear bearing or line slideway transfer mode, because the gap between its motion directly affects the measuring accuracy transmission, and along with the growth of term of life, precision can reduce gradually.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, thereby a kind of gapless displacement transmission mechanism is provided, can realize the measurements such as the high precision diameter is poor, beat, and reduce maintenance cost.
According to technical scheme provided by the invention, gapless displacement transmission mechanism comprises measuring staff, movable block, movable pressing board, top board, lower platen, measurement piece, limit shaft, sheet spring, fixation clip, fixed block, tightens screw, copper sheathing and spring assembly; Described top board, lower platen are connected by screw with the sheet spring is in the same place, described limit shaft is screwed into fixed block, copper sheathing is pressed into fixed block, utilize screw that fixation clip, sheet spring are installed on the fixed block, sheet spring and movable block are linked together by movable pressing board with screw, spring assembly passes the sheet spring and is screwed in the fixed block, and adjusts the position, the measurement piece passes the sheet spring and is fixed on the movable block with holding screw, with screw measuring staff is fixed on the movable block.
As a further improvement on the present invention, described spring assembly is comprised of spring and threaded shaft.Described spring housing is on threaded shaft.As a further improvement on the present invention, described fixed block is provided with the reservation threaded hole.
The present invention is simple in structure, compact, reasonable; Directly drive the motion of movable block by the motion of measuring staff, reached the effect of alternative traditional lever, can improve precision, increase and use function; Movable block separates making with fixed block, has realized measuring staff and the displacement of movable block gapless by the sheet spring; Can by reserving the convenient and various base plate connections of threaded hole on the fixed block, can increase use occasion; On this gapless displacement transmission mechanism, can realize the multifunctional measurings such as diameter is poor, beat, and linear good, error is little, repeatable accuracy is high, makes checkout equipment can check more high-grade size.
Description of drawings
Fig. 1 is structural front view of the present invention.
Fig. 2 is structure right view of the present invention.
Embodiment
The invention will be further described below in conjunction with drawings and Examples:
As shown in Figure 1, comprising: measuring staff 1, movable block 2, movable pressing board 3, top board 4, lower platen 5, measure piece 6, limit shaft 7, sheet spring 8, fixation clip 9, fixed block 10, tighten the compositions such as screw 11, copper sheathing 12, spring assembly 13.
The present invention links together top board 4, lower platen 5 and sheet spring 8 first by screw 14, limit shaft 7 is screwed into fixed block 10, copper sheathing 12 is pressed into fixed block 10, then utilize screw that fixation clip 9, sheet spring 8 are installed on the fixed block, sheet spring 8 and movable block 2 are linked together by movable pressing board 3 with screw 15, spring assembly 13 passes sheet spring 8 preformed holes and is screwed in the fixed block 10, and spring assembly 13 is comprised of spring and threaded shaft, and described spring housing is on threaded shaft.Measurement piece 6 passes sheet spring 8 preformed holes and is fixed on the movable block 2 with holding screw, with screw 16 measuring staff 1 is fixed on the movable block 2.
Measuring staff 1 mainly plays the contact measured workpiece among the present invention, 2 spacing and guide effects of 7 pairs of movable blocks of limit shaft, utilize the Flexible change of sheet spring 8 to make measuring staff 1, movable block 2 that the linear precision of good movement be arranged within the specific limits, spring assembly 13 provides the pressure of measuring staff 1 contact measurement workpiece, and the reset response of movable block 2.
Principle of work of the present invention and the course of work:
The present invention 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 directly 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 invention:
1, is used for load and the little occasion of distortion variation.
2, prevent corrosion phenomenon.
