Description
Technical Field
The invention belongs to the technical field of industrial laser levels, and particularly relates to a laser level and a preparation method thereof.
Background
The supporting pendant laser level appearance of current universal appearance includes several core components: a housing for holding the gimbal; the universal instrument can swing within a range of 3-5 degrees in any direction within 360 degrees; a heavy pressing piece fixed below the universal instrument is hung, is similar to a lead weight, and drives the universal instrument to swing by relying on the self weight of the heavy pressing piece; and the plurality of the line laser modules are fixed on the presser member, and each module projects a line laser beam.
Each laser is adjusted to the desired plumb or horizontal orientation and secured. When the horizontal or plumb position needs to be calibrated, as long as the level meter is placed on the surface inclined by no more than 5 degrees and corresponding to the required position to project laser, the laser beam of the first line can automatically swing along with the heavy pressing piece and finally be stabilized in the plumb and horizontal directions, and the calibration requirement is realized.
This device has the following disadvantages:
1. the universal instrument has a very small swing range and is inflexible in swing, so that a large weight is required to realize relatively precise reset. Therefore, the level and weight based on the gimbals are generally large. The overall mechanism is generally large, resulting in significant inconvenience to carry and transport.
2. Every time a line of laser beam needs to be added, one more laser module needs to be fixed, so that the manufacturing cost is higher, and the production difficulty is increased.
Disclosure of Invention
Aiming at the technical problem, the invention provides a laser level and a preparation method thereof, and solves the following problems:
1. the laser level is reduced for convenient transportation and carrying;
2. the manufacturing cost and the technical difficulty of the laser level meter are reduced.
The specific technical scheme is as follows:
the laser level comprises a transparent shell, wherein a flexible wire fixing piece is arranged at the top in the transparent shell;
the laser device also comprises a plurality of flexible wires, preferably a first flexible wire and a second flexible wire, wherein the upper ends of the first flexible wire and the second flexible wire are fixed on a flexible wire fixing piece, the lower ends of the first flexible wire and the second flexible wire are connected with a base, and a multi-mode laser head is installed in the base.
The preparation method of the laser level meter comprises the following steps:
firstly, adjusting the emission direction of the multi-mode laser head, and obtaining laser spots of 2 x 4mm at the intersection of the first column lens and the second column lens; fixing the multimode laser head at the corresponding mounting hole position of the base;
secondly, adjusting the first cylindrical lens and the second cylindrical lens to obtain two intersecting 90 linear lasers;
and thirdly, fixing one end of the first flexible wire and one end of the second flexible wire at positions close to two ends of the base, enabling the other end of the first flexible wire and the other end of the second flexible wire to penetrate through the hole position of the flexible wire fixing piece, adjusting the length of all the flexible wires between the flexible wire fixing piece and the base, enabling the base to correspondingly rotate and pitch, monitoring a linear laser beam generated by the second cylindrical lens, and fixing all the flexible wires when the linear laser beam is positioned in the same horizontal plane.
The laser-line is a sector laser which is formed by irradiating laser beams on a specific optical element and is uniformly distributed in a certain sector angle.
And fourthly, assembling the adjusted base and the flexible wire fixing piece into the transparent shell together to obtain the laser level meter.
The invention has the technical effects that:
1. the size of the laser level meter is reduced, the weight of the laser level meter is reduced, and the laser level meter is convenient to transport and carry;
2. the hardware cost and the production difficulty of the laser level meter are reduced, and the laser level meter is convenient for mass production.
