Problems solved by technology

This device can be used to measure the coordinates of the center of the hole in different cross-sections, which is the data needed to measure the verticality of the hole, but there is a problem that the movement of the probe will drive the object to be measured to move when measuring the hole diameter, so that the side hole The position of the center will move, so the coordinates of the center of the circle obtained by each measurement are not for the hole to be measured at the same position, and it is inaccurate to calculate the verticality based on these coordinates of the center of the circle

Embodiment 1

[0048] like figure 1 As shown, the present invention mainly includes a measuring mechanism 1, an X-Y mobile platform 2 and a control module. The object to be tested is placed on the X-Y mobile platform 2 for measurement. The axial lifting of the measuring hole extends into the hole to be measured, and the control module receives the feedback signal from each component and issues instructions to each component.

[0049] like figure 2 As shown, the measuring mechanism 1 includes a probe base 11 , a lifting mechanism 15 , a spherical probe 12 , a probe driving mechanism 13 , and a probe displacement sensor 14 . The spherical probe 12 is arranged on the probe base 11, and includes two fixed probes 121 and one movable probe 122, and the spherical centers of the three probes are located on the same horizontal plane. The probe driving mechanism 13 drives the movable probe 122 to move on the horizontal plane, and the probe displacement sensor 14 measures the moving distance of the...

Embodiment 2

[0065] In order to measure the coordinates of the center of each cross-section as accurately as possible, the probe can perform three or more measurements on the same cross-section to obtain three or more coordinates of the center of the circle, which are determined by the three or more centers of the circle. The coordinates of the center of the circle are the coordinates of the center of the cross section.

[0066] For this reason, on the basis of the first embodiment, a rotation mechanism 16 is also included to drive the probe holder 11 to rotate by a set angle. The rotation mechanism 16 is mainly a motor, which is connected to the lifting platform 151 and controls the rotation of the probe base 11 .

[0067] The process of measuring the coordinates of the center of a cross section is as follows (taking three measurements on the same cross section as an example):

[0068] The elevating platform 151 of the measuring mechanism 1 descends upon receiving the instruction, and dr...

Abstract

The invention discloses an oligodynamic measuring device of hole verticality, wherein, a device for measuring the movement of objects to be measured is added based on the oligodynamic measuring device of hole diameter. In other words, a sliding table which can move along an X direction and a Y direction in an oligodynamic manner is arranged below a clamp and a displacement transducer is used for feeding back the displacement of the objects to be measured relative to an initial point in the X direction and the Y direction; furthermore, a cylinder is arranged and the clamp is caused to return to the original place after the completion of one measurement. The oligodynamic measuring device of the invention has simple structure and low cost, and can accurately provide data required by the holeverticality to be calculated.

Description

【Technical field】 [0001] The invention relates to the field of measurement, in particular to a device for measuring verticality. 【Background technique】 [0002] The existing verticality measuring equipment adopts CMM machine (three-coordinate measuring machine). The verticality measurement method adopted is: the workpiece is fixed, and the CMM machine has only one probe, and each stop position of this probe can be recorded. Use this probe to scan the inner wall of each cross-section hole point by point (stop after touching the inner wall to detect the strength, and record the coordinates of this point), so as to find the center coordinates of each cross-section hole, and then obtain the verticality of the hole. The cost of this measurement method is very high, and the price of a CMM machine is 800,000 to 1,000,000 yuan / set. [0003] For this reason, a hole diameter measuring device with simple structure and low cost is designed, which mainly uses the principle of three poi...
