Description

Technical Field

[0001] The utility model relates to the technical field of mechanical engineering, in particular to a component three-coordinate detection auxiliary support device. Background Art

[0002] Three-coordinate detection has high accuracy and wide applicability. It is often used for dimensional detection of various complex parts. However, it requires that the measured part must be fixed in the spatial coordinate system during measurement, and often has more stringent requirements for the support of parts with insufficient rigidity. When supporting the measured part, it should not be allowed to move at will, nor should it deform itself due to unreasonable arrangement of support points. In response to these requirements, special brackets should generally be developed for parts with insufficient rigidity such as stamping parts, such as parts used in some automobile processing. However, in order to save project costs, there are often some measurement situations without brackets. Temporary supports are often not convenient for dealing with batch inspections, resulting in low measurement efficiency. Moreover, some drawings specify support points, and conventional means do not always meet the requirements, which also limits the detection range. In order to solve the problem of lack of special brackets and limited detection efficiency and range during three-coordinate detection of parts, it is necessary to make a three-coordinate detection auxiliary support device for parts, which can be easily combined and can meet the detection support needs of various parts.

[0019] The lifting self-locking thread pair 2 includes an internal thread and a stud; the top of the base is provided with an internal thread, and the bottom of the turntable 3 is provided with a stud, and the stud is screwed in the internal thread. The bottom of the turntable 3 is fixedly arranged with the stud, and when the lifting self-locking thread pair 2 rotates, it can provide lifting adjustment for the turntable 3.

[0020] A spherical support head 5 is provided on the extended support rod 4. Furthermore, the spherical support head 5 is made of magnetic material. Taking the extended support rod 4 as a cylindrical structure as an example, the diameter of the spherical support head 5 is not less than the radius of the extended support rod 4. During the three-dimensional detection of parts, the length of the extended support rod 4 is between 50mm and 100mm, and the diameter does not exceed 30mm. It is generally made of rigid metal material. Extended support rods 4 of different specifications are used in different positions during the three-dimensional detection of different parts, and can be flexibly combined.

[0021] The extended support rod 4 and the stud are arranged at the same center as the turntable 3 .

[0022] Taking the example that both the base 1 and the turntable 3 are cylindrical structures, the diameter of the turntable 3 is not greater than the diameter of the base 1; during the three-coordinate detection of parts, the diameter of the base 1 is between 70mm and 120mm, and the height is between 70mm and 100mm. Similarly, bases 1 and turntables 3 of different specifications can be flexibly combined.
