Description

Articulated Arm Measuring Stand

technical field

The utility model relates to a part of a measuring device, in particular to a measuring base of an articulated arm.

Background technique

The existing fixed measuring base of the portable articulated arm coordinate machine is bulky and requires a large space for placement, so it cannot be used in some on-site measurements. Although other portable measuring bases are light, they are not shared with the fixed measuring base and are not suitable for fixed The base plane has high requirements, and it cannot be used on some plates with T-shaped slots or threaded holes, which has certain limitations.

Chinese Patent Publication No. CN101556137A discloses a coordinate measuring machine for determining the measurement position of a probe, which includes an articulated arm, the first end of which is formed as a base that can be positioned on a support surface, and the second end can be moving relative to the first end, and to which the probe is attached, there is also at least one sensing unit for measuring the actual relative position of the at least one joint, and at least one computing unit for measuring the probe relative to the base and used to calibrate the measurement position in the external coordinate system by using the provided base position in the external coordinate system, the articulated arm also includes a first inclinometer for measuring relative to the calibrated in the external coordinate system The inclination of the external vector, more specifically, relative to the gravity vector. The articulated arm coordinate measuring machine has a bulky base, requires a large space for placement, and has high requirements for a fixed plane.

Utility model content

The purpose of this utility model is to provide a measuring machine base that is small in size, easy to carry, and has low requirements on the fixed plane, which can be used in conjunction with the articulated arm measuring machine, so as to solve the problem that the measuring machine base in the background technology is heavy and takes up The problem of large space and high requirements for fixed planes.

In order to achieve the above object, the technical solution of the present utility model is: an articulated arm measuring machine base, including a disc-shaped measuring machine base body, a detachably connected base is provided in the front center of the measuring machine base body, and a There is a threaded rod used to connect with the articulated arm measuring machine, and three magnetic gauge bases uniformly distributed on the circumference are fixed on the back periphery of the measuring base body. The measuring machine base is relatively small overall, and the threaded rod on the measuring machine base body is used to connect with the measuring machine. Since the base is detachably connected, when the threaded rod is damaged, the base can be replaced directly. When measuring, use the measuring machine The magnetic watch base on the back of the base is adsorbed on the fixed plane, and the requirements for the fixed plane are relatively low.

As a preference, there are arc-shaped holes on the surface of the measuring machine base body and between adjacent magnetic gauge bases, the arc centers of the arc-shaped holes coincide with the circle centers of the measuring machine base body, each of the arc-shaped holes Bolts are worn inside, and the nuts of the bolts face the front of the measuring machine base body. When some special plates (such as T-shaped plates or other irregular plates) cannot be fixed with a magnetic base, the bolts in the arc-shaped holes are used to fix the base plate.

Preferably, at least three threaded blind holes are opened on the back of the measuring base body. The measuring base can also be installed on a tripod for supporting use, and the threaded blind hole on the back of the measuring base is used to connect with the tripod.

The beneficial effect of the measuring machine base of the articulated arm of the utility model is that the measuring machine base is relatively small overall, and the threaded rod on the measuring machine base body is used to connect with the measuring machine. Since the base is detachably connected, when the threaded rod is damaged , the base can be replaced directly. When measuring, use the magnetic base on the back of the measuring base to adsorb on the fixed plane. The requirements for the fixed plane are low. If it is an irregular plane where the magnetic base cannot be used, the measuring base can be used The bolts on it are fixed.

Detailed ways

The technical solution of the utility model will be further specifically described below through the embodiments and in conjunction with the accompanying drawings.

Example:

As shown in Figures 1 and 2, an articulated arm measuring base includes a disc-shaped measuring base body 1, a base 2 is provided in the center of the front of the measuring base body 1, and the base 2 is in the shape of a bolt and includes a screw thread There are two parts, the rod and the nut, and there are four countersunk installation holes on the periphery of the nut plane. The installation holes are connected with the measuring machine base body 1 through screws 5, and the threaded rod is used to connect with the articulated arm measuring machine. The back periphery of the measuring base body 1 is fixed with three magnetic gauge bases 3 uniformly distributed on the circumference with screws 5, and arc-shaped holes are arranged between adjacent magnetic gauge bases 3. The arc center of the arc-shaped holes is in line with the measurement The center of the base body 1 coincides, the arc holes are countersunk holes, and bolts are passed through each arc hole, and the nuts of the bolts face the front of the measuring base body 1. For the convenience of manual operation, a A cross bar is also fixed on the nut, and six threaded blind holes 4 are opened on the back of the measuring machine base body 1 .

The articulated arm measuring base can be used in conjunction with the articulated arm measuring machine, and can also be used in conjunction with the tripod 6 . When used in conjunction with the articulated arm measuring machine, use the threaded rod on the base 2 to thread the articulated arm measuring machine; when connecting with the tripod 6, first remove the magnetic meter base 3 and the bolts passing through the arc-shaped hole, Then use the threaded blind hole 4 on the back of the articulated arm to measure the base and connect the tripod 6 with bolts.
