Abstract
The invention discloses a tool for checking an M value of an internal spline, which comprises a conduit, a measuring rack, a spring, a shaft, a choke plug, a dial indicator, a measuring rod and a measuring jaw. The conduit is a blind pipe of which left is solid and right is hollow; the measuring rack is sleeved outside the left section of conduit wall and the tightness of the measuring rack is adjusted by a bolt; the inside of right sector hole of the conduit is provided with the spring and the shaft; an axial elongated slot is formed on the bottom conduit wall matched with the shaft, and the elongated slot and the measuring rod are in clearance fit; the right end of the conduit is provided with the choke plug; a dial indicator rod is inserted from an axial hole of the choke plug and locked by a screw; and a dial indicator head is in elastic contact with the right end face of the shaft. In the tool for checking the M value of the internal spline, the hanging end of the measuring rack and the measuring rod are perpendicular to the conduit; the measuring jaws are arranged on the external side and the bottom end of the conduit respectively; and the line of the centers of the two measuring jaws is parallel to the centre line of the conduit. The zero position of the dial indicator is adjusted according to the designed M value before actual measurement; and the deflection relative to the zero position is offset value during measurement. The tool for checking the M value of the internal spline has high measurement accuracy and high efficiency, and particularly is suitable for the mass production of on-line check tools.
Description
Technical field
The present invention relates to a kind of length dimension cubing, particularly a kind of cubing of measuring M value of internal spline.
Background technology
It is a kind of machinery type of attachment commonly used that spline connects, and its manufacturing accuracy directly influences its fit quality, and M value of internal spline is the critical size of influence and splined shaft fit quality.The keyway of female spline is in the endoporus, and conventional measurer is difficult for accurately measuring, and prior art is inserted length bar in keyway and the method for the calibrated bolck of jumping a queue is done the M value of internal spline measurement.This measuring technique can be measured indirectly, but that measuring accuracy is influenced by human factor is bigger, and efficiency of measurement is too low, can not satisfy the batch process online detection requirements.
Summary of the invention
The present invention is primarily aimed at the deficiencies in the prior art, propose a kind of simple in structure, easy to operate, measure tool for checking M value of internal spline accurately.The direct value indication of this cubing measured value, the efficiency of measurement height satisfies and produces on-the-spot online detection requirements in batches.
The present invention is achieved through the following technical solutions technical goal.
Tool for checking M value of internal spline, it comprises conduit, amount frame, spring, axle, plug, dial gauge, gauge rod and measuring jaw.Described amount frame upper end is the open tube ring structure, directly is sleeved on the conduit left end outer wall, and low end is a straight-bar.Its improvements are: described conduit is a blind pipe, the real right hollow structure in a left side, and section tube wall bottom, a left side is provided with key and measures frame and cooperate, the degree of tightness that cooperates of bolt regulated quantity frame and conduit.The part is provided with axial elongated slot at the bottom of the hollow tube wall of the right section of conduit, the axle of clearance fit is housed to the elongated slot section at catheter shaft, spring is equipped with in the axle left side between conduit endoporus bottom, the conduit right-hand member is provided with plug, the table bar of dial gauge inserts from the plug axial hole and by screw lock, its gauge outfit and an axle right side Elastic Contact.The minor face of described gauge rod penetrates from the axial elongated slot of the right section of conduit tube wall bottom, and is connected with axle by screw.Measuring jaw is installed in the low end of described amount frame and the outside, gauge rod bottom respectively.
Said structure is at first according to the design M value of tested female spline, elder generation's adjustment amount frame is with respect to the installation site of gauge rod, preliminary definite two measuring jaw end air line distances, air line distance with two measuring jaw ball end of outside micrometer measurement is design M value then, gauge outfit contact position with axle right-hand member and dial gauge is made as zero-bit in the case, during actual measurement, the deflection of the relative zero-bit of dial gauge pointer is the actual M value of the female spline deviate of design M value relatively.
The present invention compared with prior art has following good effect:
1, designed the deviate of M value by the actual M value of dial gauge value indication female spline relatively, measure accurately, precision reaches 0.001mm.
2, measuring operation is easy, efficiency of measurement is high.
3, simple in structure, make easily.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the A-A section enlarged diagram of Fig. 1.
Embodiment
The invention will be further described with reference to the accompanying drawings below.
Tool for checking M value of internal spline shown in the drawings, it comprises conduit 1, amount frame 2, spring 3, axle 4, plug 5, dial gauge 6, gauge rod 7 and measuring jaw 8.Described conduit 1 is left real right empty blind pipe, and left section tube wall bottom is provided with key 2.2 and cooperates with amount frame 2, and amount frame 2 upper end pipe rings are opening shapes and are provided with bolt 2.1 adjusting cooperation degrees of tightness.The part is provided with axial elongated slot at the bottom of the hollow tube wall of conduit 1 right section, the axle 4 of clearance fit is housed in conduit 1 axial elongated slot section, spring 3 is equipped with in axle 4 left sides between conduit 1 endoporus bottom, conduit 1 right-hand member is provided with plug 5, the table bar of dial gauge 6 inserts from plug 5 axial holes and is locked by screw 5.1, its gauge outfit and axle 4 right side Elastic Contact.The minor face of gauge rod 7 penetrates from the axial elongated slot of section tube wall bottom, conduit 1 right side, and is connected with axle 4 by screw 7.1, and gauge rod 7 and axial elongated groove shaft are to clearance fit.The low end of amount frame 2 and gauge rod 7 are perpendicular to conduit 1 among the present invention, and the line of centres that 8, two measuring jaws 8 of measuring jaw are installed respectively outside its bottom is parallel with conduit 1 center line.The present invention is according to the installation site of the first adjustment amount frame of female spline design M value with respect to gauge rod 7, preliminary definite two measuring jaw 8 end air line distances, air line distance with two measuring jaw 8 ball end of outside micrometer measurement is design M value then, and the gauge outfit contact position with axle 4 right-hand members and dial gauge 6 is made as zero-bit in the case.Detect with inner flower-key M value cubing of the present invention, the biased commentaries on classics of pointer Relative Zero of dial gauge 6 is the actual M value of the female spline deviate of design M value relatively.Measurement result value indication of the present invention, the measuring accuracy height, it is convenient to measure, and the detection efficiency height satisfies and produces online detection requirements in enormous quantities.
