Abstract
The invention discloses an articulated arm for measuring ship ribs. The articulated arm comprises a support seat, and a plurality of rotation shafts which are arranged on the support seat and are movably connected with each other in pairs, wherein a measuring head is arranged at the movable end of a last rotation shaft; a laser sensor is arranged on the measuring head; the support seat comprises a seat body; the seat body is embedded into a long sliding rail; the sliding rail is connected with convex parts on two inner sides of the seat body by virtue of grooves in two side surfaces of the sliding rail; an elastic part is respectively arranged between the upper ends of the convex parts at two ends of the seat body and at a gap between the grooves in the sliding rail; the lower ends of the elastic parts are mounted on concave positions of the upper end surfaces of the convex parts of the seat body; sensors used for measuring the pressure applied to springs are arranged on the elastic parts. Compared with the prior art, the problems of inconvenience in use and low measurement accuracy of the existing large articulated arm for measuring ship ribs can be solved.
Description
Technical field
The present invention relates to measuring appliance manufacturing technology field, especially a kind of three-dimensional joint arm surveying instrument being applied to large ship rib and measuring.
Background technology
The existing three-dimensional coordinates measurement instrument being applied to the measurement of large ship rib generally comprises two kinds of modes, one adds clod wash on one side in man-hour while measure in rib clod wash, comprise multiple revolving shaft device, photoelectricity alignment device, laser sensor and be provided with target device outside measuring machine, this surveying instrument solves the precision controlling problem in clod wash processing well, but to the measurement of the boats and ships rib of cold roll forming, due to and complex structure, and laser ranging system and revolving shaft device etc. are without stable measurement track, thus measurement effect is very not good, and surveying instrument cost is high, it is also very inconvenient to use.
Existing another kind of surveying instrument measures after boats and ships Cold Bending Forming of Frame, and it comprises bearing, and multiple revolving shaftes be mutually flexibly connected between two that bearing is arranged, the last revolving shaft 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, the length of revolving shaft 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 and revolving shaft and 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 revolving shaft can not shrink on a large scale in, and the three-dimensional coordinates measurement instrument that measuring accuracy is high, to adapt to the measurement of large ship rib.
Summary of the invention
Problem to be solved by this invention is to provide a kind of boats and ships rib measurement joint arm, uses inconvenience, the problem that measuring accuracy is not high to solve existing large ship rib measurement joint arm.
In order to solve the problem, technical scheme of the present invention is: these boats and ships rib measurement joint arm comprises bearing, multiple revolving shaftes be mutually flexibly connected between two that described bearing is arranged, the movable end of the last revolving shaft is provided with measuring head, and described measuring head is provided with laser sensor; Described 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 two sides, 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 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, these boats and ships rib measurement joint arm by existing bearing and on the surveying instrument of multiple revolving shaftes, change the form that its susceptor design becomes microscler slide rail and the pedestal be connected by groove, make bearing and on the surveying instrument of multiple revolving shaftes 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 is connected by elastic component in groove, elastic component is provided with the sensor that measuring spring bears pressure, sensor is connected with control device, 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 accuracy of detection 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 front view of the embodiment of the present invention;
Fig. 2 is the A-A cut-open view of Fig. 1;
Fig. 3 is the B place enlarged drawing 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 measurement joint arm as shown in Figure 1 to Figure 3, it comprises bearing, bearing comprises 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 two sides, here groove 1-1 is wedge-shaped 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.Multiple revolving shaftes 6 be mutually flexibly connected between two that bearing 2 is arranged, the movable end of the last revolving shaft 6 is provided with measuring head 7, and measuring head 7 is provided with laser sensor 8.Can make like this pedestal 2 and on the surveying instrument of multiple revolving shaftes 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 surface, elastic component 4 is provided with the sensor 5 that measuring spring bears pressure, and sensor 5 and laser sensor 8 all can be connected with control device 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 revolving shaft on bearing and bearing and slide rail surface level can be measured again.
