Abstract

A device for detecting coaxial reducing shaft shoulders relates to a device for detecting the dimension of a mechanical element. The device comprises a standard plane bench and a microheight gauge, and is characterized by also comprising a height gauge block and a detection pedestal, wherein the height dimension of the height gauge block equals the standard end face spacing dimension of the two shaft shoulders of a to-be-detected workpiece, the detection pedestal is of a shaft sleeve shape, the center hole of the detection pedestal is larger than the diameter of a step-link shaft being adjacent to the large-diameter shaft shoulder of the to-be-detected workpiece, the height of the detection pedestal is larger than the spacing between the lower end face of the large-diameter shaft shoulder and the shaft bottom end face of the to-be-detected workpiece, and the upper plane and the lower plane of the detection pedestal are mutually parallel. The device has the advantages that the device has high precision in detecting the end face spacing dimension of the coaxial reducing shaft shoulders, has simple detection procedure, and can detect end face run-out error at the same time.

Description

Coaxial reducing shaft shoulder pick-up unit
Technical field:
The utility model relates to the mechanical component size detecting device.
Background technology:
Coaxial can being stuck in vernier scale, vernier micrometer with the footpath shaft shoulder or the little shaft shoulder of size difference detected diaxon shoulder end face spacing dimension between two shaft shoulders, but also can't test side surface jitter size, and the larger-size shaft shoulder end distance of coaxial reducing size detection is because of holding the depth of parallelism of vernier scale and workpiece axial line, it is big even can't detect to detect error, and the diaxon shoulder end face size of beating can't detect equally.
Use the height gauge that clock gauge is installed to detect also can't to implement if workpiece is placed on the standard flat platform, because workpiece and standard flat platform surface of contact are the workpiece bottom face rather than the shaft shoulder, microheight gauge can only detect the height of itself and workpiece bottom face to two shaft shoulders respectively, then two absolute value additive operations are drawn relative value, this detection method exists equally than mistake, because reference field all is an axial end, two absolute value stacks produce cumulative errors again, and running program is many.
During enterprise production lot workpiece, detection limit is very big, and the accuracy requirement height, and an urgent demand has simple and easy but an accurate detection method and a pick-up unit.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned defective, and a kind of coaxial reducing shaft shoulder pick-up unit is provided.
Scheme of the present utility model is: comprise standard flat platform, microheight gauge, it is characterized in that: also be provided with the height slip gauge, detect base, height slip gauge height dimension equals workpiece for measurement two shaft shoulder standard sizes, the detection base is a sleeve-like, detect centre hole of base greater than the adjacent step shaft diameter of the big footpath of the workpiece for measurement shaft shoulder, detect substructure height greater than workpiece for measurement shaft shoulder lower surface, big footpath and workpiece spindle bottom face spacing, lower plane is parallel each other on the detection base.
Advantage of the present utility model is: this device detects coaxial reducing shaft shoulder end distance dimensional accuracy height, the detection operation is simple and easy, but while test side surface jitter error.
Description of drawings:
Accompanying drawing is the utility model structural representation.
Embodiment:
The utility model comprises standard flat platform 1, microheight gauge 5, it is characterized in that: also be provided with the height slip gauge, detect base 2, height slip gauge height dimension equals 3 liang of shaft shoulder standard sizes of workpiece for measurement, detecting base 2 is sleeve-like, detect base 2 center pits and the adjacent step shaft diameter of workpiece for measurement 3 big footpath shaft shoulders clearance fit, detect base 2 height greater than workpiece for measurement 3 big shaft shoulder lower surface, footpath and 3 bottom face spacings of workpiece, lower plane is parallel each other on the detection base 2.
To detect base 2 during detection and microheight gauge 5 horizontal of clock gauge 4 will be installed on standard flat platform 1 table top, the height slip gauge is placed in detection base 2 upper surfaces, then microheight gauge 5 swing type measuring heads are close to height slip gauge upper surface, and with clock gauge 4 gauge outfit rotation direction zero-bits (this moment, clock gauge 4 will have certain decrement).Then turn-off microheight gauge 5 measuring heads take off the height slip gauge, workpiece for measurement 3 big footpath shaft shoulder lower step axle sleeves are gone into to detect base 2 medium pore horizontal to be laid, again microheight gauge 5 measuring heads are turned to, the bulb body that makes measuring head is by last path shaft shoulder upper surface, if measuring head to the right beat then clock gauge 4 readings be positive error; If measuring head left beat then clock gauge 4 readings be negative error, thereby draw two shaft shoulder spacing accurate dimensions.
If be used for flicking and rotational workpieces 3, then can read this end face axial jitter values from clock gauge 4 readings.
