Abstract
The utility model discloses a gear measuring tool, comprising a base, a measuring pedestal, a calibration block and a dial indicator, wherein the measuring pedestal is fixed on the base, a calibration hole is arranged on one side surface of the measurement pedestal in the horizontal direction, the calibration block which can freely and horizontally move is arranged in the calibration hole, the calibration hole is a blind hole, a through hole is horizontally arranged at the bottom of the blind hole, a measurement rod of the dial indicator passes through the through hole, and the end part and the measurement rod is tightly contacted with the calibration block. The gear measuring tool disclosed by the utility model has the advantages of low manufacturing cost, simple structure and convenience in operation, can quickly and exactly measure the size of an end surface boss of a left balance shaft gear and solves a measurement problem of field quantity production.
Description
Technical field
The utility model belongs to mechanical field, particularly relates to a kind of gear measurement frock.
Background technology
In present production run, be to adopt artificial mode for the measurement of left balance shaft gear, use vernier caliper measurement.Because different measuring personnel's technical merit is uneven, can cause bigger measuring error.But; This product is the critical piece in the motor car engine, and dimensional requirement is high, in batch process, can't accomplish in-process measurement fast and accurately; To cause this size Control to lose efficacy; Thereby cause not coplane of balance system of engine chain, cause system vibration and noise, have a strong impact on the serviceable life of gear, chain.
The utility model content
The purpose of the utility model just provide a kind of simple in structure, can be fast, the accurate gear measurement frock of prototype gear end face boss size, can effectively solve the problem that above-mentioned prior art exists.
The purpose of the utility model realizes through following technical proposals:
A kind of gear measurement frock comprises base, measures pedestal, calibration block and clock gauge, measures pedestal and is fixed on the base; Measure a side along continuous straight runs of pedestal and offer calibration hole; Place the calibration block that can freely move horizontally in the calibration hole, this calibration hole is a blind hole, and the blind hole bottom level is offered a through hole; The sounding rod of clock gauge passes this through hole, and the end closely contacts with calibration block.
Further, measure base top surface and offer the fastening screw that is communicated with through hole, a holding screw is threaded with this screw.
Further, the shape of said calibration hole size is complementary with the end face boss of tested gear.
Further, said calibration block and calibration hole clearance fit.
Further, the relative two sides of said calibration block horizontal direction are the plane.
The beneficial effect of the utility model is: cheap for manufacturing cost, simple in structure, easy to operate, the end face land length size of measurement of left balance shaft gear has solved on-the-spot batch process problems of measurement fast and accurately.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the utility model user mode synoptic diagram.
Embodiment
As shown in Figure 1, a kind of gear measurement frock comprises base 1, measures pedestal 2, calibration block 4 and clock gauge 5; Measure pedestal 2 and be fixed on the base 1, measure a side along continuous straight runs of pedestal 2 and offer calibration hole 3, place the calibration block 4 that can freely move horizontally in the calibration hole 3; This calibration hole 3 is a blind hole; The blind hole bottom level is offered a through hole, and the sounding rod 6 of clock gauge 5 passes this through hole, and the end closely contacts with calibration block 4.
Measure pedestal 2 end faces and offer the fastening screw that is communicated with through hole, a holding screw 7 is threaded with this screw.
The shape size of said calibration hole 3 is complementary with the end face boss 81 of tested gear 8.
Said calibration block 4 and calibration hole 3 clearance fit.
The relative two sides of said calibration block 4 horizontal directions are the plane.
As shown in Figure 2, according to the length dimension and the excircle dimension of the end face boss 81 of gear 8, process calibration hole 3 and calibration block 4 respectively; The end face of calibration block 4 is concordant with calibration hole 3 end faces of measuring pedestal 2, and clock gauge 5 is carried out " 0 " position proofread, the boss 81 of tested gear 8 is close to the pedestal end face; Thereby the sounding rod 6 that promotes clock gauge 5 moves; Directly on clock gauge 5, carry out reading at last, simple, convenient, quick, accurate, solved on-the-spot batch process problems of measurement.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
Claims (5)
1. a gear measurement frock is characterized in that: comprise base, measure pedestal, calibration block and clock gauge, measure pedestal and be fixed on the base; Measure a side along continuous straight runs of pedestal and offer calibration hole; Place the calibration block that can freely move horizontally in the calibration hole, this calibration hole is a blind hole, and the blind hole bottom level is offered a through hole; The sounding rod of clock gauge passes this through hole, and the end closely contacts with calibration block.
2. gear measurement frock according to claim 1 is characterized in that: measure base top surface and offer the fastening screw that is communicated with through hole, a holding screw is threaded with this screw.
