Abstract
The utility model provides a measuring head with a constant measuring force and a rotary measuring ball and without measuring range limitation. The measuring head comprises the measuring head, a pressure sensor, a spring, a movable sleeve, a fixed sleeve, a big stroke moving component, a small stroke moving component, a measuring rod and a driving mechanism. The measuring head with the constant measuring force and the rotary measuring ball and without measuring range limitation can select a measuring force reasonably according to measuring requirements of a measuring instrument and keep the measuring force in the measuring process and can rotate continuously to guarantee the measuring precision; and the measuring head is applicable to a contact-type continuously-moving measuring instrument, can guarantee direct contact between the measuring head and a workpiece to be measured as well as the rolling frication between the measuring head and the workpiece to be measured and can exert a constant force on the measuring surface.
Description
Technical field
The invention belongs to the dimensional measurement device, relate to the permanent dynamometry of a kind of immeasurable degree system in the precise detection technology, and the rotating measuring head of ball energy is surveyed in the gauge head end.
Background technology
When using contact formula weight instrument to measure, the gauge head of instrument directly contacts with the measurement face of measured workpiece, contacts with the reliable of surface of the work for guaranteeing the instrument gauge head, and gauge head should act on surface of the work with certain ergometry.The common elastic force that has cylindrically coiled spring, flat spring or other elastic body to produce provides ergometry.This class force measuring machine is simple, mechanism's compactness, but the ergometry that produces changes in whole range, thereby should not be used for the surveying instrument of wide range; Also have the gauge head that some can control survey power in addition, but all limited measuring stroke accordingly.
Contact measuring head is when carrying out continuous traverse measurement, and translational speed is measured in the sliding friction meeting of gauge head end and measured surface restriction, even causes surface survey trace and influence measuring accuracy.
Summary of the invention
A kind of immeasurable degree system, the ergometry that the objective of the invention is to provide in order to overcome the deficiencies in the prior art are constant, and ball is surveyed in the end can rotating measuring head.
In order to achieve the above object, technical scheme of the present invention is: the ball measuring head is surveyed in a kind of immeasurable degree system, permanent dynamometry, revolution, comprising: ball, pressure transducer, spring, quill, fixed muffle, big stroke moving-member, little stroke moving-member, measuring staff and driving mechanism are surveyed in revolution.
Fixed muffle, quill and big stroke moving-member realize turning round the big stroke of surveying ball.
Quill, spring and little stroke moving-member realize turning round the little stroke of surveying ball.
Gauge head is pressed on the pressure transducer, surveys the ergometry that ball is applied in by the pressure sensor monitoring revolution, and feeds back to the driving mechanisms control system.
Driving mechanism is surveyed ball for revolution by quill, spring and surface of the work and is applied ergometry, adjust the drive displacement amount according to the pressure transducer feedback signal.
Revolution is surveyed between ball and the axle pivoting support is installed, and realizes surveying the continuous revolution of ball.
The present invention compared with prior art has the following advantages:
1. survey ball in gauge head end can turn round, and is suitable for continuous traverse measurement, and measurement friction force is rolling friction;
2. the gaging pressure variable quantity is controlled, and to the measuring head range without limits.
Description of drawings
Accompanying drawing 1 is the measuring head structural representation;
Accompanying drawing 2 is surveyed the spherical structure synoptic diagram for revolution;
Accompanying drawing 3 is installed in synoptic diagram on the lathe cutter saddle for measuring head.
Embodiment
Below in conjunction with accompanying drawing embodiments of the present invention are described in detail:
Measuring head is as shown in Figure 3 installed on the lathe cutter saddle 13 by measurement bracket 14, can be implemented in the continuous revolution of on the machining tool external diameter in large-scale being carried out and measure.
[0021] the foregoing description only is explanation technical conceive of the present invention and characteristics, and its purpose is to allow the personage who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
