Description
Technical field
The present invention relates to measuring appliance manufacturing technology field, especially a kind of three seats for being applied to the measurement of large ship rib
Mark joint arm measuring instrument.
Background technology
The existing three-dimensional coordinates measurement instrument for being applied to the measurement of large ship rib generally comprises two ways, one kind be
One side clod wash is measured on one side when rib clod wash is processed, including it is multiple turn round shaft device, photoelectricity alignment device, laser sensor and
In the target device that is externally provided with of measuring machine, this measuring instrument solves the problems, such as the precision controlling in clod wash is processed well,
But the measurement of the ship rib to cold roll forming, due to and complex structure, and laser ranging system and the revolution nothing such as shaft device
The measure track of stabilization, thus measurement effect is not very good, and measuring instrument high cost, using being also inconvenient.
Existing another measuring instrument is measured after ship Cold Bending Forming of Frame, and it includes bearing, bearing
Multiple gyroaxises being mutually flexibly connected two-by-two of upper setting, the last gyroaxis movable end is provided with measurement head.This measurement
Instrument, due to large ship rib either height or width x length, its size is all very big, and the length of gyroaxis extremely has
Limit, thus measurement result is not accurate enough if without target device, using being also inconvenient, and large-scale measuring instrument, its
The error that bearing is inevitably produced with gyroaxis and the first-class observing and controlling part of measurement, larger deviation is caused to measurement result,
Certainty of measurement is difficult to ensure.So that a kind of gyroaxis that can make up of design can not be in contract on a large scale, and measurement essence
Degree three-dimensional coordinates measurement instrument high, to adapt to the measurement of large ship rib.
The content of the invention
Problem to be solved by this invention is to provide a kind of ship rib measurement joint arm, to solve existing argosy
The measurement of oceangoing ship rib uses inconvenience, certainty of measurement problem not high with joint arm.
In order to solve the above problems, the technical scheme is that：The measurement of this ship rib includes bearing, institute with joint arm
The multiple gyroaxises being mutually flexibly connected two-by-two set on bearing are stated, the movable end of the last gyroaxis is provided with measurement head,
The measurement head is provided with laser sensor；The bearing includes pedestal, and the pedestal is inlaid on an elongated slide rail, the cunning
Rail is connected by the groove of the slide rail two sides with the lug boss of the inner side of the pedestal two, the lug boss at the pedestal two ends
Upper end is respectively provided with an elastic component with the gap in the sliding rail groove, and the lower end of the elastic component is arranged on pedestal projection
The recessed place of portion upper surface, the elastic component is provided with the sensor that measurement spring bears pressure.
In above-mentioned technical proposal, more specifically scheme can be：The elastic component includes spring.
Further：The elastic component includes the slide plate of rubber and the rubber upper end.
By adopting the above-described technical solution, the present invention has the advantages that compared with prior art：
1st, the measuring instrument of this ship rib measurement joint arm multiple gyroaxises by existing bearing and thereon, changes
Its susceptor design makes bearing and multiple gyroaxises thereon into the elongated slide rail being connected by groove and the form of pedestal
Measuring instrument can be slided on slide rail, to measure the two-dimensional of ship rib along the length direction of large ship rib, be made
With very convenient, and simple structure, low cost of manufacture；
2nd, this ship rib measurement joint arm is connected in groove by elastic component, and elastic component is provided with measurement spring and bears
The sensor of pressure, sensor is connected with control device, two differences for bearing pressure of spring, can calculate pedestal both sides horizontal
To the deviation of horizontal plane, the deviation of the actual generation of the measurement head with laser sensor is obtained final product, to overcome bearing in the prior art
The inadequate problem of accuracy of detection is caused with the deviation of observing and controlling part, to ensure certainty of measurement.
Brief description of the drawings
Fig. 1 is the front view of the embodiment of the present invention；
Fig. 2 is the A-A sectional views of Fig. 1；
Fig. 3 is enlarged drawing at the B of Fig. 2.
Specific embodiment
The embodiment of the present invention is described in further detail below in conjunction with the accompanying drawings：
This ship rib measurement joint arm as shown in Figure 1 to Figure 3, it includes bearing, and bearing includes pedestal 2, pedestal 2
It is inlaid on an elongated slide rail 1, slide rail 1 is connected by the groove 1-1 of the two sides of slide rail 1 with the lug boss 2-1 of 2 liang of inner sides of pedestal
Connect, groove 1-1 here is wedge-shaped slot, and lug boss 2-1 is wedge-shaped protrusion.In other embodiments, can also be dovetail groove etc.
All form of grooves.The multiple gyroaxises 6 being mutually flexibly connected two-by-two set on bearing 2, the activity of the last gyroaxis 6
End is provided with measurement head 7, and measurement head 7 is provided with laser sensor 8.The measurement of pedestal 2 and multiple gyroaxises 6 thereon can so be made
Instrument can be slided on slide rail 1, to measure the two-dimensional of ship rib along the length direction of large ship rib, use ten
Divide convenient, and simple structure, low cost of manufacture.The gap of 1-1 in the upper end of the lug boss 2-1 at the two ends of pedestal 2 and the groove of slide rail 1
An elastic component 4 is respectively provided with, elastic component 4 here includes spring, and the lower end of spring is arranged on the lug boss 2-1 upper surfaces of pedestal 2
Recessed 2-2 at, elastic component 4 is provided with measurement spring and bears the sensor 5 of pressure, and sensor 5 and laser sensor 8 can be with
Control device 5 is connected.Two differences for bearing pressure of spring, can calculate the deviation on the both sides of pedestal 2 and transverse horizontal face, i.e.,
The deviation of the actual generation of measurement head of laser sensor must be carried, to ensure certainty of measurement.
In other embodiments, elastic component can also be without using spring, it is possible to use rubber, is set in rubber upper end and slided
Plate.Can make to be contacted by slide plate between pedestal and slide rail, both keep pedestal normally to be slided with slide rail, bearing can be measured again
And the deviation of the gyroaxis on bearing and slide rail horizontal plane.
