Embodiment Construction
[0026] The adjustment and measurement of the middle rod circle blister using the present invention will be described in detail below in conjunction with the accompanying drawings.
[0027] Such as image 3 , 4 , Shown in 5, 7, 8, 9, the present invention comprises upper end fixing device, lower end supporting device. The upper end fixing device is composed of a hollow ring 1, a conical hollow cylinder 2, and a limit bolt 3. The lower end supporting device is a circular gasket 4. There is a tapered hole 5 in the center of the front of the circular gasket 4. The opposite edge of the circular gasket 4 Three small conical feet 6 are evenly distributed, and the material of this device can be processed by any metal or alloy material.
[0028] The hollow ring 1 and the conical hollow cylinder 2 can be welded or integrally processed with materials. Three bolt holes are distributed on the hollow ring 1 at an angle of 120 degrees, and the limit bolt 3 is screwed into the three bolt ho...

The invention discloses a measuring centering rod bubble adjusting device and a matched usage method, for mainly calibrating of a centering rod bubble in engineering measurement. The device comprises an upper end fixing device and a lower end support device, wherein the upper end fixing device consists of a hollow ring, a conical hollow cylinder and a limiting bolt; the lower end support device is a round gasket; a conical hole is formed in the center of the front side of the round gasket; three small conical feet are uniformly distributed on the edge of the back side of the round gasket. The device can be made of any metal or alloy material and can be directly inserted into a round hole in a head part of a tripod of an ordinary instrument for measuring so as to calibrate the centering rod bubble. The device has the advantages of small size,, convenience in carrying over, convenience in mounting and application, high calibration precision, simple structure, unlikeliness to have faults and the like, and can be widely applied to engineering measurement to solve the problem that the round bubble of a centering rod or a similar centering rod is calibrated by vast operators.
Description
technical field [0001] The invention relates to an adjustment device and a matching use method thereof, in particular to an adjustment device for measuring centering rod circle blisters and a matching use method thereof, which is mainly used for engineering measurement centering rod round blister correction. Background technique [0002] The centering rod is mainly composed of a round metal rod with a diameter of 30mm~35mm, a round blister installed on the metal rod, and two support rods. There are three adjustment screws on the round blister, and the vertical axis of the metal rod is connected with the vertical axis of the circular blister. Parallel, when working, align the lower end of the centering rod with the tip of the centering rod to the target point to be measured, adjust the two support rods to center the round blister, and make the centering rod vertical so that the observation target point on the centering rod coincides with the underground target point. In order...
