Description

A kind of measurement apparatus of leading screw pitch circle dimensional variations amount
Technical field:
It the utility model is related to a kind of measurement apparatus of leading screw pitch circle dimensional variations amount.
Background technology:
The conventional detection mode of existing leading screw pitch circle dimensional variations amount is:Corresponding rule are loaded onto in the measurement head of micrometer The steel ball of lattice, then raceway detects one by one.This detection method efficiency is low, and because each raceway can not possibly detect, Testing result is not comprehensive, is usually just found in assembling, certain section of leading screw raceway pitch circle off-dimension.
The content of the invention:
The utility model is to provide a kind of leading screw pitch circle dimensional variations to solve the above-mentioned problems of the prior art The measurement apparatus of amount.
There is technical scheme used by the utility model:A kind of measurement apparatus of leading screw pitch circle dimensional variations amount, including turn Axle, chuck, rotation thimble, pressure sensor, supporting plate, slide rail and sliding block, the chuck are fixedly connected with rotating shaft, the leading screw One end is fixed on chuck, and rotation thimble is connected on leading screw other end end face, and slide rail is located at the lower section of leading screw, and slide rail and silk Thick stick is parallel, and supporting plate is slidably connected on slide rail by sliding block, and pressure sensor is fixed on supporting plate, and the sense of pressure sensor It should hold in the raceway for stretching in leading screw.
Further, the induction end of the pressure sensor is connected with contact.
Further, the contact is spherical shape.
Further, the chuck grabs chuck for three.
The utility model has the advantages that:
The utility model can draw the detection data of leading screw raceway pitch circle dimensional variations amount, and the detection data are accurate, comprehensive, The pitch circle dimensional variations amount in raceway total length can be not only measured, but also can know that the circularity feelings of the pitch circle on each radial section Condition.
Brief description of the drawings:
Fig. 1 is the utility model structure chart.
Embodiment:
The utility model is further described below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of measurement apparatus of leading screw pitch circle dimensional variations amount of the utility model, including rotating shaft 1, chuck 2, Rotation thimble 3, pressure sensor 4, supporting plate 5, slide rail 6 and sliding block 7, chuck 2 are fixedly connected with rotating shaft 1, and the left end of leading screw 100 is consolidated Due on chuck 2, rotation thimble 3 is connected on the right-hand member end face of leading screw, and slide rail 6 is located at the lower section of leading screw, and slide rail 6 and leading screw 100 is parallel, and supporting plate 5 is slidably connected on slide rail 6 by sliding block 7, and pressure sensor 4 is fixed on supporting plate 5, and pressure sensing The induction end of device 4 is stretched in the raceway of leading screw 100.
Pressure sensor in the utility model selects model CYZ102 pressure sensors, can also select other models Pressure sensor, pressure sensor by data measured by single-chip microcomputer in use, be transferred to computer, the work of pressure sensor Process is same as the prior art, therefore the utility model repeats no more.
The utility model is causes pressure sensor preferably to be slided in the raceway of leading screw 100, in pressure sensor 4 Induction end is connected with contact 41, and the contact 41 is spherical shape.
Chuck 2 in the utility model grabs chuck for three.
In use, pressure sensor 4 by contact 41 in radial displacement(Y-direction)Numerical value be transmitted to computer, according to chuck 2 The helical pitch of rotating speed, leading screw 100, computer can be by the radial displacements of the contact of any position in the X-axis direction of contact 41(Y side To)Variation be converted into the total length pitch circle dimensional variations amount of leading screw raceway and the circularity of pitch circle.
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art For art personnel, some improvement can also be made on the premise of the utility model principle is not departed from, these improvement also should be regarded as The scope of protection of the utility model.
