Abstract
The invention discloses an arm-variable articulated coordinate measuring machine and relates to the technical field of coordinate measuring machines. The arm-variable articulated coordinate measuring machine comprises a measuring arm, wherein two ends of the measuring arm are respectively in articulated connection with a measuring head and a base measuring arm; the base measuring arm is mounted on a base; the measuring arm comprises a first fixed arm, a movable arm and a second fixed arm which are sequentially connected with one another; one end of the movable arm sleeves the exterior of the first fixed arm; the movable arm is in threaded connection with the first fixed arm; the other end of the movable arm is connected with one end of the second fixed arm by virtue of a bolt. Compared with the prior art, the arm length of the measuring arm is adjustable; the application range of the measuring machine can be widened; when the arm-variable articulated coordinate measuring machine is used for measuring small-sized parts, the arm length is regulated and the size of the measuring space is reduced, so that the measurement accuracy of the small-sized parts can be improved.
Description
Technical field
The present invention relates to coordinate measuring machine technical field, especially a kind of change shoulder joint formula coordinate measuring machine.
Background technology
Articulated coordinate machine is a kind of nonopiate coordinate-measuring instrument, and it, compared with traditional normal coordinates measuring machine, has tandem-in-space structure, thus has that degree of freedom is large, measurement space is open, a flexible and convenient operation and be suitable for the features such as in-site measurement.But, the gage beam of existing articulated coordinate machine is all fixing brachium, and when adopting the change shoulder joint formula coordinate measuring machine of this structure to measure small size part, the part of its measurement space often than measured is much larger, this just causes measurement space redundancy, reduces measuring accuracy; The immutable structure of this brachium, makes the usable range of measuring machine be subject to larger restriction.
Summary of the invention
The object of this invention is to provide a kind of change shoulder joint formula coordinate measuring machine, this immutable problem of brachium that can solve the gage beam of existing articulated coordinate machine.
In order to solve the problem, the technical solution used in the present invention is: this change shoulder joint formula coordinate measuring machine comprises gage beam, the two ends of described gage beam are connected with gauge head and pedestal gage beam respectively by joint, described pedestal gage beam is installed on a pedestal, it is characterized in that: described gage beam comprises the first arms, swing arm and the second arms that connect successively, one end of described swing arm is sleeved on outside described first arms, described swing arm is threaded with described first arms, and the other end of described swing arm is connected by bolt one end with described second arms.
In the technical scheme of above-mentioned change shoulder joint formula coordinate measuring machine, technical scheme can also be more specifically: the outer wall of described first arms and described swing arm is equipped with telltale mark.
Further, the shifting block that the outer wall of described swing arm is fixed with.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect: simple to operate, the brachium of gage beam is adjustable, the usable range of measuring machine can be expanded, when measuring small size part, reduce measurement space size by adjustment brachium, thus improve the measuring accuracy to small size part.
Accompanying drawing explanation
Fig. 1 is the structural representation of this change shoulder joint formula coordinate measuring machine.
