Example 1:

as one typical application scenario of the present application, a double-layer base for installing and positioning a laser provided by the present embodiment is specifically illustrated by taking laser positioning adopted by a control system in publication No. CN110755142B as an example, a use state is shown in fig. 6, a specific structure is shown in fig. 1, and the double-layer base includes a second base 7 for detachably connecting with a laser device, a first base 4 is detachably and floatingly installed on the second base 7, and a floating base 2 for installing a laser head 1 is slidably installed on the first base 4. The first base 4 is connected with the second base 7 through three fasteners 3 distributed in a triangular shape, and a spring ring 6 is sleeved on any one fastener 3 and is positioned between the first base 4 and the second base 7. The advantage of adopting three fasteners 3 that are the triangular distribution to connect and cooperate spring ring 6 to adjust lies in that stability is high, and the controllability of regulation is good, and is convenient, quick, high-efficient. The problem that in the prior art, when the spherical seat is adjusted in a floating mode, the adjustment amount is not easy to master, or the adjustment amount is too large or too small, and more time is needed for accurate adjustment can be solved. The operation is more convenient when the structure is adopted for adjustment, and the three fasteners 3 are distributed in a triangular shape, so that the operator can adjust the laser beam to the target position or the target position only by adjusting the two fasteners 3 at most no matter which direction the laser beam and the target position have, and the adjustment precision has lower requirement on the skill of the operator. Simultaneously, adopt the mode of spring ring 6 can effectually prevent the not hard up of base in the use, improve the stability of laser head precision.

The laser head 1 is a key device for emitting laser to make a target positioning point visible, and the double-layer base for installing the laser head 1 is used for adjusting the laser head 1 to make the laser beam indicate a target position. In order to enable the laser beam indicating position to coincide with the preset position, accurate indication needs to be achieved by changing a double-layer base for installing the laser head 1. Specifically, the second base 7 is fixedly connected with the laser device and serves as a stable fixed structure, and the first base 4 and the second base 7 are installed in a floating structure and used for adjusting the deflection angle of the laser head 1; when the laser beam is deflected, the adjustment is achieved by correcting the floating angle between the first base 4 and the second base 7. The floating structure can be realized in various ways, such as a ball socket, a universal joint, etc. in the prior art. It should be noted that the double-layer base provided by the present embodiment can only satisfy a single linear adjustment, such as a horizontal or vertical direction, but the double-layer base can be linearly adjusted in a desired direction according to actual situations by being installed horizontally or vertically. Laser head 1 is any one in dot laser head, a word laser head and the cross laser head. In the embodiment, a straight laser head is taken as an example for explanation, as shown in fig. 6, a plurality of double-layer bases can be used in combination, so that laser beams emitted by a plurality of laser heads 1 can be converged in the air to realize positioning of space specific target points by laser beams at different angles. Specifically, in fig. 6, four laser heads 1 are used, and any one of the laser heads 1 is installed by a double-layer base structure, and when a certain point of space needs to be located, the operation mode is as follows:

firstly, placing a standard checking tool in an area where a target point is located, preferably using the standard checking tool with scales or marks, and driving a double-layer base to a specified position through a coordinate which needs to be indicated by laser equipment;

secondly, observing whether the laser beams emitted by the laser heads 1 are exactly mapped on the indication check points or the scale marks of the standard check tool one by one, and if the laser beams are superposed, checking the accuracy of the laser beam of the next laser head 1 until the last laser head 1 is checked; if the laser beam does not coincide with a predetermined check point or graduation mark, an adjustment is required.

Thirdly, if the actual laser beam deviates from the standard check point or the standard scale mark in the relative sliding direction of the floating base 2 and the first base 4, the relative position between the floating base 2 and the first base 4 is firstly adjusted, so that the laser beam is overlapped with the standard check point or the standard scale mark or is at the minimum distance. If the laser beams can be superposed, the laser beams and the target position do not deflect and only have linear offset; if the laser beam and the target position cannot be overlapped, the linear offset and the angular deflection exist simultaneously between the laser beam and the target position.

And fourthly, adjusting the laser beam and the target position to the minimum distance, and then adjusting the three fasteners 3 until the laser beam and the target position coincide. The principle of the adjustment is as follows: when the screwing fastener 3 is screwed in the screwing direction, the laser beam deflects towards the cover fastener 3, otherwise, when the fastener 3 is loosened, the laser beam deflects towards the opposite direction; any two fasteners 3 are moved according to the actual deflection condition, so that the laser beams can be coincided with the target positions. It should be noted that, due to the elastic force of the spring ring 6 on the fastening member 3, the second base 7 and the first base 4 do not come loose from spontaneous combustion, resulting in failure of the precise pointing position.

In this embodiment, three fastening members 3 are distributed in an isosceles or equilateral triangle in the plane of the first base 4. The fastener 3 with the required adjustment amount and the corresponding direction can be estimated through the deflection amount of the current laser beam and the actual offset amount of the laser beam during actual adjustment by adopting the distribution of an equilateral triangle or an isosceles triangle, so that the adjustment efficiency can be greatly improved in the adjustment process.

Example 2:

on the basis of embodiment 1, in order to implement linear adjustment in the horizontal direction or the vertical direction to change the horizontal position or the vertical position of the laser beam, as further shown in fig. 1-5, the first base 4 has a floating cavity 42 for accommodating the floating base 2, a rib 43 integrally formed with the first base 4 and used for limiting the sliding of the floating base 2 is arranged in the floating cavity 42, a screw rod 5 penetrating through the floating base 2 and rotatably connected with the first base 4 is installed between the rib 43 and the inner side wall of the floating cavity 42, and an adjusting hole 41 corresponding to the end position of the screw rod 5 is arranged on the first base 4. When adjustment is performed, a tool, such as a screwdriver, penetrates through the adjustment hole 41 to screw the screw rod 5, the screw rod 5 and the first base 4 are in a rotating connection state, the relative position relation between the screw rod 5 and the first base 4 cannot be changed by rotation of the screw rod 5, but the screw rod 5 and the floating base 2 are in through threaded connection, so that the floating base 2 can be driven to slide along the ribs 43 while the screw rod 5 is rotated, and the sliding direction is controlled by clockwise or anticlockwise rotating the screw rod 5. It is worth mentioning that the pitch of the thread on the screw rod 5 can be reduced as much as possible according to the accuracy requirement, and the smaller the pitch, the higher the accuracy of the adjustment can be achieved, and the lower the energy saving requirement for the operator.

In this embodiment, the floating base 2 includes the clamping part 21 and the installation part 23 that are coaxially and fixedly connected, the floating part 22 is further disposed between the clamping part 21 and the installation part 23, and the length of the floating part 22 is adapted to the width of the floating cavity 42. The smaller the fit clearance between the floating portion 22 and the ribs 43, the higher the accuracy, and likewise the smaller the fit clearance between the floating cavity 42 and the floating base 2, as one of the means for facilitating the operation, the contact surfaces between all the clearance-fitted structural members are provided with a smooth hard plating layer, such as a chromium plating layer, and the surfaces are coated with a lubricating material.

In order to facilitate the installation of the laser head 1, the clamping part 21 is provided with an expansion joint 24 dividing the clamping part 21 into a first part and a second part along the axial direction, and the first part and the second part are both provided with installation holes fastened by screws. The tightness adjustment is realized by adjusting the fastening degree of the screw.
