Embodiment Construction

[0013] Embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings:

[0014] Such as Figure 1 to Figure 3 The shown articulated arm support for measuring ribs of this ship includes a seat body 2, which is embedded on a long slide rail 1, and the slide rail 1 passes through the grooves 1-1 on both sides of the slide rail 1 It is connected with the protrusions 2-1 on both inner sides of the seat body 2, the groove 1-1 here is a wedge-shaped groove, and the protrusion 2-1 is a wedge-shaped protrusion. In other embodiments, it may also be in the form of all grooves such as dovetail grooves. In this way, the measuring instruments of the seat body 2 and the plurality of rotating shafts 6 on it can slide on the slide rail 1, so as to measure the two-dimensional size of the rib of a large ship along the length direction of the rib of a large ship, which is very convenient to use and simple in structure. Low manufacturing ...

Abstract

The invention discloses a articulated arm support for ship rib measurement, which includes a seat body, the seat body is embedded on a long slide rail, and the slide rail passes through grooves on both sides of the slide rail and the The protrusions on the two inner sides of the seat body are connected, and the upper ends of the protrusions at both ends of the seat body and the gap in the groove of the slide rail are respectively provided with an elastic piece, and the lower ends of the elastic pieces are installed on the seat. In the depression on the upper end surface of the convex part of the body, the elastic member is provided with a sensor for measuring the pressure of the spring. Compared with the prior art, the present invention can solve the problems of excessive measurement deviation and low measurement accuracy of the existing joint arm support for rib measurement of large ships.

Description

technical field [0001] The invention relates to the technical field of measuring instrument manufacturing, in particular to a support for a three-coordinate articulated arm measuring instrument used in rib measurement of large ships. Background technique [0002] An existing three-coordinate measuring instrument applied to the measurement of large-scale ship ribs is to measure after the ship ribs are cold-formed. A measuring head is provided at the movable end of a rotary shaft. This kind of measuring instrument, because the rib of a large ship is all very large in terms of height and width, the length of the rotary shaft is very limited, so if there is no target device, the measurement result is not accurate enough, and it is very inconvenient to use. Moreover, for large-scale measuring instruments, the support generally includes a foot or a seat body, and the inevitable errors generated by the measurement and control components such as the rotating shaft and the measuring...
