Description
Technical field
The present invention relates to the survey tool used in a kind of machining, particularly a kind of measurement head location structure.
Background technology
During measurement head is as machine tooling, the contact implemented using machine tool chief axis installation measurement head to workpieces processing is surveyed
Amount, is the measuring method that is commonly used in modern mechanical processing, measurement head in use, because measuring point is different and more
Secondary use, the chaining pin and chaining pin seat of measurement head need that relative displacement occurs with measurement casing, so the manufacture measurement of measurement head
The reseting precision that precision and chaining pin occur after relative displacement with measurement casing is the key for ensureing measurement head measurement accuracy, existing
In similar measurement head, chaining pin is fixed on chaining pin seat, and the positioning of chaining pin seat and measurement casing is employed as movable part
Upper 120 ° of chaining pin seat is distributed three groups of positioning cylinders being arranged in pairs, and measures and positioning ball is set on casing, by positioning ball fixed
It is spacing between circle of position post, realize chaining pin seat with measuring the positioning of casing.The shortcomings that prior art is that 1 due to movable part
The upset of chaining pin seat when, three groups of positioning cylinders mutually produce interference, make the upset of its chaining pin seat difficult, cylinder serious wear, reduction
The physical life of measurement head.The upper three groups of positioning cylinder structures of 2 chaining pin seats increase chaining pin seat axial dimension, make measurement head entirety axle
To larger, the measurement accuracy of measurement head is reduced.
Goal of the invention
During to solve existing measurement head chaining pin seat upset, three groups of positioning cylinders mutually produce interference, make the upset of its chaining pin seat difficult,
Cylinder serious wear, the physical life and the upper three groups of positioning cylinder structures of chaining pin seat for reducing measurement head add chaining pin seat axial dimension
Greatly, the technical problem of the measurement accuracy of measurement head is reduced, the present invention discloses a kind of measurement head location structure.
The present invention realizes that the technical scheme that goal of the invention uses is：A kind of measurement head location structure, including：Chaining pin and measurement
Casing, chaining pin are formed with measurement casing through chaining pin seat and are located by connecting, and described chaining pin is fixed with chaining pin seat lower end coaxial line
Connect, locking ball mounting hole has been uniformly arranged into 120 ° on chaining pin seat circumference, locking ball is fixedly installed on locking ball peace
Fill in hole, locking ball partial denudation chaining pin seat lower surface, on described measurement casing end face circumference corresponding with chaining pin seat into
On hexagonal angle separated time, a pair of axis locating dowel parallel with angle separated time is symmetrical arranged, described measurement head casing center is provided with logical
Hole, chaining pin seat lower end is raised be arranged on formed in through hole chaining pin seat drive chaining pin with measure casing can opposing oscillatory activity even
Connect.
The beneficial effects of the invention are as follows simple in construction, positioning element light abrasion, service life is long, axial dimension is small, precision
It is high.
The present invention will be described in detail below in conjunction with the accompanying drawings.
Accompanying drawing 1 is the cross-sectional view of the embodiment of the present invention 1.
Accompanying drawing 2 is accompanying drawing 1A-A diagrammatic cross-sections.
Accompanying drawing 3 is chaining pin seat 1 and chaining pin 2 and the measurement connection relationship diagram of casing 3.
Accompanying drawing 4 is the cross-sectional view of the embodiment of the present invention 2.
In accompanying drawing, 1 chaining pin seat, 1-1 locking balls mounting hole, 1-2 locking balls, 1-3 are raised, 1-4 resets lower magnet, 1-
5 top pits, 1-6 centre with endlong movements, 2 chaining pins, 3 measurement casings, 3-1 through holes, 3-2 reset upper magnet, 4 locating dowels.
Embodiment
Referring to accompanying drawing, a kind of measurement head location structure, including：Chaining pin and measurement casing, chaining pin is through chaining pin seat and measurement
Casing is formed and is located by connecting, and described chaining pin 2 is fixedly connected with the lower end coaxial line of chaining pin seat 1, into 120 ° on the circumference of chaining pin seat 1
Locking ball mounting hole 1-1 is uniformly arranged, locking ball 1-2 is fixedly installed in locking ball mounting hole 1-1, locking ball
The lower surface of 1-2 partial denudation chaining pins seat 1, into hexagonal angle separated time on described measurement casing 3 end face circumference corresponding with chaining pin seat 1
On, a pair of axis locating dowel 4 parallel with angle separated time is symmetrical arranged, the described center of measurement casing 3 is provided with through hole 3-1, surveys
The lower end projection 1-3 of needle stand 1 is arranged in through hole 3-1, is formed chaining pin seat 1 and is driven chaining pin 2 can opposing oscillatory with measuring casing 3
It is flexibly connected.
Because the positioning ball 1-2 on movable part chaining pin seat 1 is revolving body, so when chaining pin seat 1 overturns or swung, positioning
Do not interfered between ball 1-2, overturn or swing the abrasion for freely, substantially reducing positioning ball 1-2 and locating dowel 4, improve measurement
The physical life of head, the structure design of the positioning ball 1-2 installation sites on chaining pin seat 1 reduce chaining pin seat axial dimension, raising
The measurement accuracy of measurement head.
In the embodiment of the present invention, described chaining pin 2 and the lower end coaxial line fixed connection structure of chaining pin seat 1 to be threadedly coupled or
Tight fit grafting.
In the embodiment of the present invention, to ensure that chaining pin seat 1 resets, the lower magnetic of reset is provided with the described upper surface of chaining pin seat 1
Iron 1-4, measurement casing 3 and the upper surface correspondence position of chaining pin seat 1, which are provided with, resets upper magnet 3-2, reset lower magnet 1-4 with it is multiple
Realize that chaining pin seat 1 resets by magnetic force between the upper magnet 3-2 of position.
In the embodiment of the present invention, to ensure that chaining pin seat 1 resets, top pit is provided with the described upper surface of chaining pin seat 1
1-5, measurement casing 3 are provided with centre with endlong movement 1-6 with the upper surface correspondence position of chaining pin seat 1.
