Embodiment 1

[0047] like figure 1 As shown, the cylindricity measuring device provided in this embodiment includes a workbench 300, and the workbench 300 includes a base body 100 and an installation frame 200. The installation frame 200 is installed on the base body 100 through elastic connectors, and a scanning structure is installed on the installation frame 200. 209. Linear drive mechanism and rotary drive mechanism, the scanning structure 209 is provided with a part accommodating hole 214, the side wall of the part accommodating hole 214 is provided with a measuring head, and the measuring head is connected with the data processing device 400.

[0048] In this embodiment, as figure 1 and figure 2 As shown, the base body 100 is a cylindrical structure, the mounting frame 200 includes an upper frame body 201 and a lower frame body 202, the upper frame body 201 and the lower frame body 202 are both annular plate-shaped structures, and the elastic connecting member is an elastic rod 203....

Embodiment 2

[0056] The difference between this embodiment and Embodiment 1 is that, in Embodiment 1, the elastic connecting member is an elastic rod. In this embodiment, the elastic connector is a spring, the mounting frame is supported on the base by the spring, one end of the spring is connected and fixed with the mounting frame, and the other end of the spring is connected and fixed with the base. When the force is applied, the mounting seat can transmit the force to the spring, and the spring is deformed by the force, so that the mounting bracket can be deflected to the position where the part receiving hole is aligned with the part to be measured, and when the part to be measured enters the part receiving hole Afterwards, the spring can also drive the mounting frame to return to the initial position by its own elastic force.

Embodiment 3

[0058]The difference between this embodiment and Embodiment 1 is that in Embodiment 1, the elastic connecting pieces extend laterally and are arranged in a plurality of circumferential directions of the mounting frame, and the two ends of each elastic connecting piece are respectively connected with the seat body and the mounting frame. Connection is fixed. In this embodiment, the elastic connecting pieces are arranged vertically extending, and the number of elastic connecting pieces is two. The two elastic connecting pieces are arranged on both sides of the part accommodating hole, and the upper and lower ends are respectively supported and fixed to the mounting frame and the base. Ensure that when the robot exerts a force on the mounting frame through the part to be tested, the acting force can apply sufficient yaw moment to the two elastic connectors. After the two elastic connectors are deformed, the mounting bracket can also be swayed to the part accommodating hole and the...

Abstract

A cylindricity measuring device provided by the present invention comprises a workbench, the workbench comprises a mounting rack, the mounting rack is provided with a scanning structure, a linear driving mechanism and a rotation driving mechanism, the scanning structure is provided with a part accommodating hole, and the wall surface of the part accommodating hole is provided with a measuring head. The linear driving mechanism is used for enabling the to-be-measured part and the part containing hole to move relatively, the rotation driving mechanism is used for enabling the to-be-measured part and the part containing hole to rotate relatively, the measuring head is made to complete measurement of the peripheral face of the to-be-measured part, the workbench comprises a base, and the installation frame is installed on the base through an elastic connecting piece. And the elastic connecting piece is used for enabling the mounting rack to deflect relative to the seat body, so that when a to-be-detected part is put into the part accommodating hole, the mounting rack can deflect to a position where the part accommodating hole is aligned with the to-be-detected part. The cylindricity measuring device provided by the invention can effectively solve the technical problem in the prior art that parts are easily clamped when a cylindricity measuring device is matched with a robot for use.

Description

technical field [0001] The invention relates to the technical field of shape tolerance measuring devices, in particular to a cylindricity measuring device. Background technique [0002] Cylindricity is an index to measure the shape error of cylindrical objects. In the production of enterprises, shaft parts need to be measured for their cylindricity after processing, and the parts are classified according to the measurement results. The existing cylindricity measuring device includes a workbench, the workbench includes an installation frame, a scanning structure is installed on the installation frame, a part accommodating hole is arranged on the scanning structure, a measuring head is arranged on the wall surface of the parts accommodating hole, and the measuring head is connected with a data processing device. In addition, a linear drive mechanism and a rotary drive mechanism are also installed on the mounting frame. At present, the measurement of cylindricity mainly relie...
