Problems solved by technology

[0005] The weak point of the marking instrument in the above-mentioned prior art is: as figure 1 As shown, for marking multiple straight lines 3 parallel to the horizontal stakeout reference line 2 on the target plane 1 (practical applications such as: for interior decoration, it is used to mark the upper and lower sides of the window frame, where the The lower part is preset as the horizontal stakeout reference line), the existing solution is to set the laser marking instrument on a tripod, such as figure 2 As shown, when a horizontal stakeout laser surface 4 intersects the target plane 1, a horizontal stakeout reference line 2 is projected on the target plane 1, and the connecting rod on the tripod is manually lifted to raise and lower the line marker, and then the target plane 1 marks a straight line parallel to the horizontal stakeout reference line 2. The operation of this scheme requires the cooperation of two people, which is time-consuming and laborious; in addition, the accuracy of the straight line 3 marked in the existing scheme is often low, that is, it is often consistent with the horizontal stakeout reference line 2 The parallelism is not high

Embodiment 1

[0035] The laser line marking instrument of this embodiment includes an electric rotating base 10, and a turntable 11 that rotates and cooperates with the electric rotating base 10, such as Figure 7 As shown, a bracket 22 is set on the turntable 11, a gravity automatic leveling mechanism 21 is suspended on the bracket 22, a first laser 20 is fixedly arranged on the gravity automatic leveling mechanism 21, and a top plate 23 is set on the top of the bracket 22, as Figure 10 As shown, the top of the gravity automatic leveling mechanism 21 cooperates with the bearing seat 25 arranged on the lower end surface of the top plate 23 through the cross pivot 24, so that the gravity automatic leveling mechanism 21 can be in a natural drooping state below the top plate 23 to ensure The laser surface emitted by the first laser 20 is kept horizontal.

[0036] The laser marking instrument also includes a first swing arm 32, a first drive mechanism for driving the first swing arm 32 to rot...

Embodiment 2

[0040] The working method of the above-mentioned laser marking instrument, such as Figure 4 to Figure 6 shown, including the following steps:

[0041] A. Place the laser marking instrument in front of the target plane 1 to be constructed, so that the stakeout laser surface 4 emitted by the first laser 20 and the signal laser surface 5 emitted by the second laser 30 are projected onto the target plane 1; the gravity is automatic The leveling mechanism 21 is in a naturally drooping state under the action of gravity, so that the stakeout laser surface 4 emitted by the first laser 20 remains horizontal, and the intersection of the stakeout laser surface 4 and the target plane 1 forms a horizontal stakeout reference line 2 .

[0042] B, start the second motor, drive the second screw mandrel 73 to rotate, so that the second swing arm 35 rotates around the second rotating shaft 34, adjust the mounting plate 36 until the level sensor 33 shows that it is in a horizontal state, and the...

Abstract

The invention relates to a laser line marking instrument component and a working method thereof. The laser line marking instrument component comprises a first laser capable of emitting a lofting laser plane, and a second laser capable of emitting a signal laser plane, wherein the lofting laser plane is projected to a target plane to obtain a horizontal lofting datum line; and the signal laser plane, when in a horizontal state, and the horizontal lofting datum line are at different heights. The laser line marking instrument component also comprises a horizontal rotating shaft, wherein the second laser is in running fit with the rotating shaft; the signal laser plane projects a straight line on the target plane; when the second laser rotates along with the rotating shaft, the straight line moves up and down on the target plane; and when the straight line moves to the horizontal lofting datum line, if the straight line and the horizontal lofting datum line are completely superposed, the second laser is driven to rotate around the rotating shaft, and then a straight line parallel to the horizontal lofting datum line can be obtained at any height on the target plane.

Description

technical field [0001] The invention relates to the technical field of laser measuring equipment, in particular to a laser line marking instrument component and a working method thereof. Background technique [0002] When building decoration construction, doors and windows or equipment installation, leveling, setting out and measuring will take you a lot of time and energy. The line marking instrument brings convenience to leveling, setting out and measuring. The laser line marking machine uses semiconductor lasers as the light source. After beam expansion, a high-brightness laser line is formed on the target wall. [0003] The host of the existing multi-line laser marking instrument includes: a vertical laser base and a horizontal laser located on one side of the middle of the vertical laser base in the height direction (for outputting a horizontal stakeout reference line, that is, it can be formed on the target plane W A horizontal line), four groups of vertical lasers th...
