A cone-shaped positioning head (1) and a positioning scale (2) are arranged at the front end of the utility model by the same coaxial line. An index head (4) which is sheathed on the positioning scale (2) is fixedly locked through a lock screw (7). A telescopic vernier (3) is perpendicular to the axial cord of the positioning scale (2) and is arranged on the rotational part of the index head (4). Both ends of the positioning scale (2) are supported on two adjustable brackets (5). The device is convenient to operate and has high measurement accuracy. The spatial three-dimensional coordinate of a measured point of any cross section can be measured.
Description
The utility model relates to a kind of major diameter object space three-dimensional coordinate measurement device, belongs to the device of measuring the closed structures interior shape of major diameter.
In the prior art, picture fish torpedo type iron mixing vehicle one class integral body is the closed structures microscler, that the cross section is rounded, measurement to its interior shape is adopted following method more: draw a long line in body of heater on the axis, telescopic board foot and long line perpendicular and be adjacent to long line after turn around around it, determine its shape according to the change in radius in each cross section of body of heater.During measuring, this method has elasticity in order to the long line itself that substitutes the body of heater axis, can produce bigger amount of deflection in the practical application, scalable board foot can't be with vertical as the real maintenance of the long line of axis, axially the measuring position is difficult to accurately determine, and fully by manually-operated, thereby measuring accuracy and work efficiency are low, can not satisfy the production needs.Chinese patent CN2082396U discloses a kind of " interior tray (well) diameter detector ", on the instrument frame left and right sidesing post is housed, is supported on inner walls by dog screw, the chi frame that can horizontally rotate links to each other with the instrument frame by coupling spindle, telescopic secondary chi is housed on the chi frame, on the secondary chi main scale is housed.This detector only can be used to measure the diameter of housing, and can't determine its locus.
The purpose of this utility model provides a kind of easy to operate, and the measuring accuracy height can be measured the major diameter object space three-dimensional coordinate measurement device of arbitrary section measured point space three-dimensional coordinate, to increase work efficiency, satisfies needs of production.
The purpose of this utility model realizes by following measure.
A kind of major diameter object space three-dimensional coordinate measurement device, have taper positioning head, Position Scale, scalable vernier, dividing head and adjustable support, taper positioning head and Position Scale coaxial cable are installed in its front end, dividing head is sleeved on the Position Scale, be locked by lock-screw, scalable vernier is installed on perpendicular to the Position Scale axis on the rotating part of dividing head, and the two end supports of Position Scale is on two adjustable supports.
Be positioned on the adjustable support of Position Scale rear end bidimensional coordinate translation device is installed, the rear end of Position Scale is supported on the bidimensional coordinate translation device, so that the translation of Position Scale, Position Scale is on the testee axis when guaranteeing to measure.
Position Scale is made by hollow bar, is guaranteeing that it has enough bending strengths with when reducing amount of deflection, alleviates the weight of Position Scale.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.
Accompanying drawing is the structural representation of the utility model major diameter object space three-dimensional coordinate measurement device.
The utility model major diameter object space three-dimensional coordinate measurement device as shown in the figure, mainly is made up of taper positioning head 1, Position Scale 2, scalable vernier 3, dividing head 4, adjustable support 5 and bidimensional coordinate translation device 6.Taper positioning head 1 is installed in its front end with Position Scale 2 coaxial cables, and Position Scale 2 is made by hollow bar.Dividing head 4 is sleeved on the Position Scale 2, is locked by lock-screw 7.Scalable vernier 3 is installed on the rotating part of dividing head 4 perpendicular to Position Scale 2 axis.The front end of Position Scale 2 directly is supported on the adjustable support 5, is positioned on the adjustable support 5 of Position Scale 2 rear ends bidimensional coordinate translation device 6 is installed, and the rear end of Position Scale 2 is supported on the bidimensional coordinate translation device 6.
During work, whole device places in the tested major diameter object, and taper positioning head 1 is inserted in the axis centre of location hole of testee one end, adjusts two and regulates support 5 and bidimensional coordinate translation device 6, and the axis of Position Scale 2 and the axis of testee are coincided.Move dividing head 4 to the sectional position that need detect along Position Scale 2, it is fixing with dividing head 4 to tighten lock-screw 7.Measure the distance of each measuring point by scalable vernier 3, and can directly read the angle of each measuring point by dividing head 4 apart from body axis.Cross section, place, measured point, determined the 3 d space coordinate of measured point apart from axial line distance and corner.
The advantage that the utility model compared with prior art has is: simple in structure, and behaviour Make things convenient for, can accurately detect the space three-dimensional coordinate of measured point on the arbitrary section, improve Accuracy of detection and operating efficiency, can satisfy the needs of actual production fully.
