At present, there is a kind of road cutting machine that can cut out a circle. Its working principle is to set the front wheel as the central axis facing the working circle center of the road cutting machine, and the central axis of the rear wheel can be adjusted to face the working circle center of the cutting machine. , the traditional cutting disc is replaced by a parabolic cutting disc, which can cut a circle around the working circle center of the cutting machine, but this kind of circular road cutting machine can not accurately locate the center of the circular pavement to be cut. The disadvantage is that the center of the road surface to be cut is often determined by visual inspection, and the cut circle often has an error with the predetermined circular position

Embodiment Construction
[0009] The present invention will be further described below in conjunction with the accompanying drawings.
[0010] like figure 1 As shown, the locator includes 3 strips of equal length, each strip is provided with a screw hole 1 at the end, and a round hole 2 is provided at the end away from the screw hole, and the 3 strips are flexibly connected at the round hole.
[0011] In the present invention, the distance between the round hole and the end with the screw hole is set according to the needs, and is suitable for the radius of the required cutting circle. For example, the radius of the circle to be cut is 50 cm, and the distance between the round hole and the screw hole It is set to 50cm, that is to say, a round hole is opened 50cm away from the screw hole, and the three strips are set in this way.
[0012] The 3 strips are flexibly connected at the round hole. When using this locator, the 3 strips rotate around the overlapping round hole, and the two crosses present a c...

The invention discloses a locator for quickly locating a cutting circle center for a pavement cutting machine. The locator comprises three long strips with same length, wherein the tail end of each long strip is provided with a screw hole (1); one end of each long strip, which is far away from the screw hole, is further provided with a round hole (2); and the three long strips are movably connected at the round holes. The locator for quickly locating the cutting circle center for the pavement cutting machine has the beneficial effects that based on the principle of determining a unique circle by three points, when the locator is crossed on the ground in a certain angle, each long strip can be fixed on the ground through the screw hole at the tail end, at the moment, the round holes of the three long strips are superposed, and the superposition position of the round holes is the circle center of a pavement to be cut.
Description
technical field [0001] The invention relates to a positioning device, in particular to a positioner for quickly positioning the center of a cutting circle for a road cutting machine. Background technique [0002] Road cutting machine is an important equipment used in road construction, and is widely used in grooving, resting and cutting of concrete and asphalt pavement. At present, there is a kind of road cutting machine that can cut out a circle. Its working principle is to set the front wheel as the central axis facing the working circle center of the road cutting machine, and the central axis of the rear wheel can be adjusted to face the working circle center of the cutting machine. , the traditional cutting disc is replaced by a parabolic cutting disc, which can cut a circle around the working circle center of the cutting machine, but this kind of circular road cutting machine can not accurately locate the center of the circular pavement to be cut. The disadvantage is t...
