Abstract
The invention discloses an articulated arm supporting seat for measuring a ship rib. The articulated arm supporting seat comprises a seat body, wherein the seat body is embedded on an elongated sliding rail; the sliding rail is connected with lug bosses on two inner sides of the seat body through grooves in two side surfaces of the sliding rail; an elastic piece is arranged in a gap between the upper end of each of the lug bosses at two ends of the seat body and the corresponding groove of the sliding rail; the lower end of each elastic piece is mounted at a sunk part of the upper end surface of the corresponding lug boss of the seat body; each elastic piece is provided with a sensor which is used for measuring the bearing pressure of a spring. Compared with the prior art, the articulated arm supporting seat for measuring the ship rib has the advantage that the problems of over-large measured deviation and low measurement accuracy of the existing articulated arm supporting seat for measuring a large ship rib can be solved.
Description
Technical field
The present invention relates to measuring instrument manufacturing technology field, especially a kind of bearing being applied to the three-coordinate joint arm surveying instrument that large ship rib is measured.
Background technique
Existing a kind of three-dimensional coordinates measurement instrument being applied to the measurement of large ship rib measures after boats and ships Cold Bending Forming of Frame, it comprises bearing, multiple turning axlees be mutually flexibly connected between two that bearing is arranged, the last turning axle movable end is provided with measuring head.This surveying instrument, because no matter large ship rib is height or width x length, its size is all very large, and the length of turning axle is very limited, if thus do not have target device, measurement result is not accurate enough, and it is also very inconvenient to use.And large-scale surveying instrument, its bearing generally comprises leg or pedestal, and with the turning axle on it with measures the error that first-class observing and controlling parts inevitably produce, cause larger deviation to measurement result, measuring accuracy is difficult to guarantee.Thus need to design and a kind ofly can make up that turning axle can not shrink on a large scale, and the three-dimensional coordinates measurement instrument bearing that measuring accuracy is high, to coordinate boats and ships rib measurement joint arm, jointly complete large ship rib and measure accurately.
Summary of the invention
Problem to be solved by this invention is to provide a kind of boats and ships rib measurement joint arm bearing, excessive to solve existing large ship rib measurement joint arm bearing measured deviation, the problem that measuring accuracy is not high.
In order to solve the problem, technological scheme of the present invention is: these boats and ships rib measurement joint arm bearing comprises pedestal, described pedestal is inlaid on a microscler slide rail, described slide rail is connected with the lug boss inside described pedestal two by the groove of described slide rail bi-side, gap in the upper end of the lug boss at described pedestal two ends and described sliding rail groove is respectively provided with an elastic component, the lower end of described elastic component is arranged on the recessed place of described pedestal lug boss upper-end surface, and described elastic component is provided with the sensor that measuring spring bears pressure.
In technique scheme, more specifically scheme can be: described elastic component includes spring.
Further: described elastic component includes the slide plate of rubber and described rubber upper end.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, existing susceptor design is become the form of microscler slide rail and the pedestal be connected by groove by these boats and ships rib measurement joint arm bearing, make bearing and on the surveying instrument of multiple turning axlees can slide on slide rail, to measure the two-dimensional of boats and ships rib along the length direction of large ship rib, use very convenient, and structure is simple, low cost of manufacture;
2, these boats and ships rib measurement joint arm bearing is connected by elastic component in groove, elastic component is provided with the sensor that measuring spring bears pressure, sensor is connected with control gear, the difference of bearing pressure of two springs, the deviation in transverse horizontal face, pedestal both sides can be calculated, obtain the deviation of the actual generation of measuring head with laser sensor, the problem causing testing precision inadequate with the deviation overcoming bearing and observing and controlling parts in prior art, to ensure measuring accuracy.
Accompanying drawing explanation
Fig. 1 is the plan view of the embodiment of the present invention;
Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is the B place enlarged view of Fig. 2.
Embodiment
Below in conjunction with accompanying drawing, the embodiment of the present invention is described in further detail:
These boats and ships rib is as shown in Figure 1 to Figure 3 measured and is used joint arm bearing, it includes pedestal 2, pedestal 2 is inlaid on a microscler slide rail 1, slide rail 1 is connected by the lug boss 2-1 of groove 1-1 and pedestal 2 liang of inner sides of slide rail 1 bi-side, here groove 1-1 is wedge slot, and lug boss 2-1 is that wedge shape is protruding.In other embodiments, can also be all form of grooves such as dovetail groove.Can make like this pedestal 2 and on the surveying instrument of multiple turning axlees 6 can slide on slide rail 1, to measure the two-dimensional of boats and ships rib along the length direction of large ship rib, use very convenient, and structure is simple, low cost of manufacture.In the upper end of the lug boss 2-1 at pedestal 2 two ends and slide rail 1 groove, the gap of 1-1 is respectively provided with an elastic component 4, here elastic component 4 comprises spring, the lower end of spring is arranged on the recessed 2-2 place of pedestal 2 lug boss 2-1 upper-end surface, elastic component 4 is provided with the sensor 5 that measuring spring bears pressure, and sensor 5 can be connected with control gear 5.The difference of bearing pressure of two springs, can calculate the deviation in pedestal 2 both sides and transverse horizontal face, obtains the deviation of the actual generation of measuring head with laser sensor, to ensure measuring accuracy.
In other embodiments, elastic component can not also use spring, can use rubber, arranges slide plate in rubber upper end.Can make to be contacted by slide plate between pedestal with slide rail, both keep pedestal and slide rail normally to slide, the deviation of turning axle on bearing and bearing and slide rail horizontal plane can be measured again.
Claims (3)
1. a boats and ships rib is measured and is used joint arm bearing, it is characterized in that: comprise pedestal, described pedestal is inlaid on a microscler slide rail, described slide rail is connected with the lug boss inside described pedestal two by the groove of described slide rail bi-side, gap in the upper end of the lug boss at described pedestal two ends and described sliding rail groove is respectively provided with an elastic component, the lower end of described elastic component is arranged on the recessed place of described pedestal lug boss upper-end surface, and described elastic component is provided with the sensor that measuring spring bears pressure.
2. boats and ships rib measurement joint arm bearing according to claim 1, is characterized in that: described elastic component includes spring.
