Description

Technical Field

[0001] This utility model belongs to the field of laser projection positioning technology, specifically relating to a high-precision target point base used in a laser projection positioning system. Background Technology

[0002] In a laser projection positioning system, a single or multiple camera is needed to identify pre-set target points on the workpiece to locate the workpiece's position. This guides the laser projection positioning system to project the required laser pattern onto the workpiece, which in turn guides workers to process the workpiece or assemble parts according to the position of the laser pattern.

[0003] How to quickly and conveniently fix the target point relative to the workpiece is a common problem encountered in practical work. Therefore, a high-precision target point base for laser projection positioning system is provided to solve the target point installation problem. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a high-precision target point base for use in a laser projection positioning system.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] A high-precision target point base for a laser projection positioning system includes a stop block and a pressure block, wherein the stop block and the pressure block are threadedly connected.

[0007] The pressure block includes a main body and a screw disposed on one side of the main body;

[0008] The stop block is provided with a screw hole adapted to the screw rod, the screw rod is locked into the screw hole, and a clamping space is formed between the pressure block and the stop block;

[0009] The stop block has an assembly hole on the other side opposite to the screw hole for installing the target point.

[0010] In this utility model, the target point is provided with a coded point or a non-coded point, and there is a pin for installation on one side of the target point. A through hole is pre-set on the workpiece, and the two sides of the workpiece are defined as side A and side B respectively.

[0011] The screw on the pressure block passes through the through hole from side A of the workpiece and reaches side B of the workpiece. The stop block is threadedly connected to the screw from side B of the workpiece. Specifically, the screw hole of the stop block is screwed into the screw of the pressure block. The workpiece is located in the clamping space formed between the pressure block and the stop block. As the screw and the screw hole are continuously screwed into each other, the clamping space becomes smaller and smaller. When the pressure block and the stop block are close to both sides of the workpiece, the screw and the screw hole can no longer be screwed into each other, and the stop block and the pressure block are installed.

[0012] Subsequently, the pin of the target point is inserted into the assembly hole of the pressure block. By rotating the pin in the assembly hole, the orientation of the target point is changed. When setting the coding point, the orientation of the coding point can also be changed so that the coding point faces the projection binoculars, which makes it easier for the binocular camera to identify the target point and align the coordinate system.

[0013] The beneficial effects of this utility model are: simple and convenient installation with high installation accuracy. By continuously screwing the screw and screw hole together, the clamping space is continuously reduced. When the pressure block and the stop block are close to both sides of the workpiece, the screw and screw hole can no longer be screwed together, and the stop block and pressure block are installed. The pin of the target point is inserted into the assembly hole of the pressure block. By rotating the pin in the assembly hole, the orientation of the coding point can be changed so that the coding point faces the projection binoculars, which facilitates the binocular camera to identify the target point and align the coordinate system.

[0026] Example 1

[0027] like Figure 1-6 As shown, this embodiment provides a high-precision target point base for a laser projection positioning system, including a stop block 1 and a pressure block 2. The stop block 1 and the pressure block 2 are connected by threads. The stop block 1 is made of aluminum A6061 and the surface is treated with an oxidation blackening process.

[0028] The pressure block 2 includes a main body 21 and a screw 22 disposed on one side of the main body. The screw 22 has an M8 thread specification and a length of 11 mm. The main body 21 is a cylinder with a diameter of 25 mm and a height of 14 mm. The main body is made of rubber, and the screw 22 is made of stainless steel.

[0029] The stop block 1 is provided with a screw hole 12 for the screw 22. The screw hole 12 has an M8 thread specification, a pitch of 1.25 mm, and a depth of 10 mm. The screw 22 is locked into the screw hole 12, and a clamping space is formed between the pressure block 2 and the stop block 1.

[0030] The stop block 1 has a mounting hole 11 on the other side of the screw hole 12 for mounting the target point 3. The mounting hole has a size of φ10 and a depth of 10 mm.

[0031] In this embodiment, a coding point is provided on target point 3, a pin for installation is provided on one side of target point 3, a through hole is pre-set on the workpiece, and the two sides of the workpiece are defined as side A and side B respectively.

[0032] The screw 22 on the pressure block 2 passes through the through hole from side A of the workpiece and reaches side B of the workpiece. The stop block 1 is threadedly connected to the screw 22 from side B of the workpiece. Specifically, the screw hole 12 of the stop block 1 is screwed into the screw 22 of the pressure block 2. The workpiece is located in the clamping space formed between the pressure block 2 and the stop block 1. As the screw 22 and the screw hole 12 are continuously screwed into each other, the clamping space becomes smaller and smaller. When the pressure block 2 and the stop block 1 are close to both sides of the workpiece, the screw 22 and the screw hole 12 can no longer be screwed into each other, and the stop block 1 and the pressure block 2 are installed.

[0033] Subsequently, the pin of target point 3 is inserted into the assembly hole 11 of pressure block 2. By rotating the pin in the assembly hole 11, the orientation of the target point is changed. When setting the coding point, the orientation of the coding point can also be changed so that the coding point faces the projection binoculars, which makes it easier for the binocular camera to identify target point 3 and align the coordinate system.

[0034] Example 2

[0035] like Figure 4 As shown, this embodiment provides a high-precision target point base for use in a laser projection positioning system. The difference from embodiment 1 is that the outer surface of the stop block 1 is provided with a flat surface 13 that facilitates the installation and removal of a wrench.

[0036] In this embodiment, the function of the plane 13 is to increase the contact area with the wrench, thereby improving the stability of the wrench when holding the stop block 1. The stop block 1 can be easily rotated by the wrench, so that the screw 22 can rotate in the screw hole 12.

[0037] Example 3

[0038] like Figure 5 As shown, this embodiment provides a high-precision target point base for use in a laser projection positioning system. The difference from embodiment 1 is that the stop block 1 is provided with a side threaded hole 14 that communicates with the assembly hole 11.

[0039] In this embodiment, a suitable plug is locked into the side threaded hole 14. The plug can be used to hold the pin of the target point 3 in place, so that the target point 3 cannot rotate and the coding point remains fixed.

[0040] Example 4

[0041] This embodiment provides a high-precision target point base for use in a laser projection positioning system. The difference from Embodiment 1 is that the coaxiality of the screw hole 12 and the mounting hole 11 is less than or equal to 0.03 mm.

[0042] In this embodiment, a high degree of coaxiality can ensure the positional accuracy of target point 3.

[0043] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
