Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting, in particular to a steel cutting angle deviation detection device. Background Art

[0002] During laser cutting on a multi-axis CNC machine tool, the clamping seat is generally placed vertically, and one end of the long strip of steel is clamped on the clamping seat so that the steel as a whole is horizontal, and then the three-dimensionally movable laser head is combined with the rotatable clamping seat to achieve rapid cutting of the steel.

[0003] When the steel is clamped on the clamping seat, due to the long length of the steel itself and the fact that it is generally only fixed at one end, the steel is prone to a small angular deviation at the end, which in turn causes inaccurate positioning during subsequent laser processing, affecting the processing accuracy. To this end, the existing method for angle detection of steel is mostly achieved by directly setting sensors around the steel, detecting the relative distance of the steel through the sensor, and comparing it with the predetermined distance to form a difference to achieve the detection effect. The above method is generally only suitable for single-position steel processing needs, and cannot adapt to the use needs of multi-point cutting of steel. At the same time, the dust generated during steel processing is also likely to cause pollution and damage to the sensor, so it needs to be improved. Utility Model Content

[0020] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments, wherein the same components are indicated by the same reference numerals.

[0021] like Figure 1-2As shown, a steel cutting angle deviation detection device includes a base 1 and a detection base 2. A sensor unit 3 is provided on the base 1 and the detection base 2. The sensor unit 3 is used to detect the distance between the workpiece surface and the base 1 / detection base 2.

[0023] Specifically, the guide rail 6 is a cylinder guide rail 6 .

[0024] Preferably, the detection terminal 4 is a distance sensor, and its specific principle is that when the laser irradiates the target object and reflects back, the sensor receives the reflected laser and calculates its round-trip time to achieve distance measurement.

[0025] When in use, the guide rail 6 is connected to the frame, and the base 1 and the detection seat 2 are further installed on the guide rail 6, and the base 1 and the detection seat 2 are driven to move on the guide rail 6 by the guide rail 6, and the steel is further clamped on the clamping seat. In the initial state, the base 1 corresponds to the end of the steel close to the clamping seat to detect the distance from the end of the steel to the base 1, and the detection seat 2 moves to the end of the steel away from the clamping seat to detect the distance from the end to the detection seat 2 bracket, and then the difference formed by the two distances is used to complete the detection of the steel angle. At the same time, when the clamping seat rotates, the plane of the steel changes, and the new plane can be quickly detected through the base 1 and the detection seat 2.

[0026] At the same time, the guide rails 6, the base 1 and the detection base 2 can be arranged around the workpiece to complete the simultaneous detection of the four sides of the base 1 to meet the laser cutting processing requirements at different positions.

[0028] The detection terminal 4 can be concealed by the installation groove 8 in cooperation with the protective layer 5 , thereby reducing the pollution or damage to the detection terminal 4 caused by smoke and dust.

[0029] Preferably, mounting ends 9 are formed at both ends of the guide rail 6 , and the guide rail 6 is mounted to the rack via the mounting ends 9 .

[0030] Specifically, the mounting end 9 can be connected to the frame by means of bolts or the like.

[0031] Due to the limitations of installation space and installation position of different racks, the guide rail 6 may easily be angularly offset after installation. Therefore, a horizontal device 10 is provided in the guide rail 6 , and the horizontal device 10 is used to detect the horizontal angle of the guide rail 6 .

[0032] Specifically, the leveling device 10 is any one of the prior art devices capable of detecting leveling.

[0033] Preferably, a correction device 11 is provided on the guide rail 6 , and the correction device 11 is used to correct the horizontal angle of the guide rail 6 .

[0034] By setting the correction device 11, the horizontal angle of the guide rail 6 can be adjusted after installation, thereby improving the detection accuracy.

[0035] Preferably, a mounting hole 12 is provided on the guide rail 6 , and the correction device 11 includes a limiting bolt, which is threadedly connected to the mounting hole 12 .

[0036] When in use, the position of the limit bolt can be adjusted according to the horizontal angle detected by the horizontal device 10, so that the limit bolt contacts the frame to adjust the angle of the guide rail 6.

[0037] Preferably, the number of the mounting holes 12 is at least 2 and they are arranged along the length direction of the guide rail 6 .

[0038] The provision of multiple mounting holes 12 can meet the requirements of different rack installation positions.
