Abstract
The invention discloses a circle center measurement device, including a central disc, wherein a left support arm and a right support arm which are both extendable are connected with the central disc, a laser beam device is arranged on the top of each of the left and right support arms, and particularly light rays transmitted by the laser beam devices are respectively perpendicular to the left and right support arms. The circle center measurement device provided by the invention is simple in structure, small in size, accurate in display and practical.
Description
Technical field
The invention relates to a kind of center of circle measurement mechanism.
Background technology
The method of traditional positioning centre still adopts construction with ruler and compasses, the method troublesome poeration, and efficiency is lower, also there is the method adopting vertical panel location, but owing to adopting sheet material to measure, be subject to the stop of sheet material when locating, accurately cannot locate, easily cause bias.
Innovation and creation content
For the problems referred to above, a kind of center of circle measurement mechanism is carried in the invention.
Center of circle measurement mechanism, comprise center disk, also comprise one end to be connected with center disk, the other end is provided with left socle arm and the right support arm of laser wire harness device, described left socle arm and right support arm are telescopic, and the original light of described laser wire harness device is vertical respectively with right support arm with left socle arm.
Further, described left socle arm and right support arm are that axle center rotates with center disk, form the angle of 0 ° ~ 180 °.
Further, described center disk is also provided with fixed screw.
Compared with prior art, the beneficial effect of the invention is: the mode of abandoning tradition vertical panel location, adopts laser positioning, and be not subject to the size restriction of circle to be measured on the one hand, visual determination is more accurate on the other hand, can precise positioning.
Accompanying drawing explanation
Fig. 1 is the structural drawing of the invention.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the invention is described in further detail:
As shown in Figure 1, center of circle measurement mechanism, comprise center disk 1, also comprise one end to be connected with center disk, the other end is provided with left socle arm 2 and the right support arm 3 of laser wire harness device 4, described left socle arm 2 and right support arm 3 are telescopic, and the original light of described laser wire harness device 4 is vertical respectively with right support arm with left socle arm.
Described left socle arm and right support arm are that axle center rotates with center disk, form the angle of 0 ° ~ 180 °.Described center disk is also provided with fixed screw 5.
During concrete use, the angle of adjustment left and right support arm, makes the end of center disk, left socle arm, the end of right support arm is at circumferential position, open laser wire harness device, because the wire harness of laser wire harness device is all vertical with left and right support arm, its intersection point necessarily passes home position.Due to laser wire harness device launch for laser wire harness, its width is very little, and the position location of intersection point is more accurate, and staff can adopt mark instrument by this record simultaneously, easy to operate.
