Embodiment 1

[0031] Such as Figure 1 to Figure 4 As shown, the center positioning device of the circular hole in this embodiment is used to determine the center (center) of a circular hole whose two ends are flat. On the workpiece, the circular hole 10 is a through hole, and the circular hole 10 The planes on which the end faces at both ends are located are parallel to each other.

[0032] Such as figure 1 As shown, the center positioning device for the circular hole includes two positioning discs 7 of equal diameter, a vertical threaded connecting rod 6, a positioning plate 5, and a connecting part. The connecting part is used to install the positioning disc 7 and the vertical threaded connecting rod 6, which includes a connecting block 8 and a transverse connecting rod 9 fixed laterally on the connecting block. The two positioning discs 7 are arranged coaxially and fixed or fixed respectively. The upper end of the vertical threaded connecting rod 6 is connected with the connecting block 8,...

Embodiment 2

[0040] Figure 5 to Figure 9 The drawing device between the centers of the circular holes in this embodiment is shown. The line drawing device between the center of the circular hole includes two circular hole center positioning devices and the line drawing bending plate 3 in embodiment 1. The circular hole center positioning devices are the first circular hole center positioning device 1 and the second circular hole center respectively Positioning device 2.

[0041] Such as Figure 5 Image 6 As shown, in the first circular hole center positioning device 1, the connecting block 8 is provided with a vertical sliding groove 81, and a slider 82 is provided in the sliding groove 81. The sliding direction of the slider 82 is the same as the vertical threaded connecting rod 6 The axis 61 is parallel. The slider 82 is provided with a screw 84 and a beam emitting device 83. When the slider 82 is slid to a proper position, the slider 82 can be locked with the connecting block 8 by the s...

Embodiment 3

[0046] Such as Picture 10 As shown, this embodiment shows a device for measuring the distance between the centers of circular holes. In this device, its structure is basically the same as the first circular hole center positioning device 1 and the second circular hole center positioning device 2 in the second embodiment. The difference is that there is no need to draw a line bending plate 3 in the distance measuring device between the centers of the circular holes, and the beam emitting device 83 can not only emit a light beam, but also has a distance measurement function. When measuring the distance between the centers of two circular holes, the first circular hole center positioning device 1 and the second circular hole center positioning device 2 are respectively placed on the two circular holes of the structure under test, first visually perform rough aiming, and adjust the beam emitting device 83 And the direction of the light receiving plane, so that the light beam emitte...

Abstract

The invention relates to a round hole center positioning device. In order to solve the problems of high cost and low efficiency of positioning the center of a round hole in a workpiece, the inventionprovides a round hole center positioning device which is used for determining the center of a round hole with two end surface being flat surfaces. The device is characterized by comprising two positioning discs with the same diameter, a vertical threaded connecting rod, a positioning flat plate and a connecting component, wherein the two positioning discs are coaxially mounted at two ends of the connecting component, the vertical threaded connecting rod is mounted on the connecting component, the positioning flat plate is mounted at the lower end of the vertical threaded connecting rod and canmove along the axis of the vertical threaded rod through a thread on the vertical threaded rod, the axis of the vertical threaded connecting rod is perpendicular to the positioning flat plate and perpendicularly intersects with the axes of the positioning discs, and the two positioning discs are in central symmetry about the axis of the vertical threaded connecting rod. The round hole center positioning device is simple in structure and convenient to manufacture, and can position centers and axes of round holes with different diameters at different positions on a structural member.

Description

Technical field [0001] The invention relates to a measuring device, more specifically, to a device for positioning the center of a circular hole, a device for drawing a line between the centers of the circular hole and a distance measuring device. Background technique [0002] At present, for the lofting of structural parts based on the center of the circular hole as the reference line, the method of manufacturing tooling, the on-site welding method, or even the method based on experience is generally adopted. For measuring the distance between the axis of two circular holes or the distance from the center of the circular hole to the plane, it is difficult to determine the center of the circular hole or the axis of the circular hole, which makes it difficult to accurately obtain the measurement data of the distance between the two circular holes or the distance from the axis of the circular hole to a certain plane. . [0003] For the lofting of structural parts based on the center...
