Description

Multi-direction adjustment laser indicating device for cutting machine

technical field

The utility model relates to a cutting machine, in particular to a multi-directional adjustment laser indicating device of the cutting machine which can adjust the projection angle of laser light in multiple directions in response to various sawing work requirements.

Background technique

The sawing work of the general cutting machine is mainly that the operator draws the ink line on the part to be cut off, and then aligns the circular saw blade with the ink line to cut the workpiece, and then the workpiece can be cut into the size desired by the operator. Due to the high-speed rotation It is difficult to align the circular saw blade with the ink line, so the cutting machine is usually equipped with an indicator device, which can project a laser indicator line on the surface of the workpiece, so that the operator can clearly know that the circular saw blade The position where the knife will be cut.

Referring to Fig. 1, a traditional indicating device 10 is fixed on the side of the axis of a circular saw blade 100, which includes a hollow casing 11 and a laser lamp 12 installed inside the casing 11, the casing There is a through hole 111 outside the body 11, which can project a little light source outward from the laser lamp 12. Since the indicating device 10 is fixed on the circular saw blade 100, as the circular saw blade 100 rotates at a high speed, the indicating device 10 The emitted point light sources will converge to form a straight indicating line. The advantage of the above-mentioned indicating device is that it can project an indicating line covering the workpiece regardless of the size of the workpiece. However, it has its shortcomings in use, because the indicating device 10 is fixed On one side of the circular saw blade 100, there will be a small gap between the through hole 111 and the surface of the circular saw blade 100, so the indicator line projected by the indicating device 10 and the real cutting position of the circular saw blade 100 will have errors, which are accurate. The accuracy is not good, and the position of the indicating line is fixed and cannot be adjusted left and right. If the operator is used to measuring and sawing on the other side of the circular saw blade 100, the indicating device 10 is not applicable.

Referring to Fig. 2, a traditional cutting machine 2 has a working platform 3 for placing a workpiece 200, a support 4 pivotally connected to the rear of the working platform 3, and a sliding slide mounted on the support 4. Unit 5, a front seat 6 affixed to the front of the sliding unit 5, and a sawing device 7 that is axially connected to the front seat 6 and has a circular saw blade 8 inside, the operator presses down on the sawing device 7 to The workpiece 200 is sawed. At the same time, the sawing device 7 can be pushed forward and backward by the sliding unit 5. In this way, the circular saw blade 8 can completely saw off the large workpiece 200. The front seat 6 of the cutting machine 2 is in a relatively circular position Another indicator device 20 is provided at the position of the saw blade 8, as shown in Figure 3, the indicator device 20 includes a set of movable seat 21 arranged in a slot 601 inside the front seat 6, and a set of movable seats embedded in the movable seat 21. The laser lamp 22, a screw located at the side of the front seat 6 can screw to drive the adjustment piece 23 of the movable seat 21 to move left and right, and a cover 24 located outside the slot hole 601 (see Figure 2 ), the cover 24 has a window hole 241 corresponding to the position of the laser light 22, so that the laser light 22 can project a laser indicator line 25 toward the direction of the working machine 3 through the window hole 241. The projection position of the line 25 is the same as the cutting position of the circular saw blade 8, but the operator can drive the movable seat 21 to move left or right by screwing the adjustment member 23, so that the indicator line 25 can follow the direction of the operator. Change the left and right position according to the idea.

The advantage of the above-mentioned indicating device 20 is that the position of the indicating line 25 can be adjusted left and right to meet the needs of sawing work, but there are still shortcomings in its use, because the laser light 22 is fixed on the movable seat 21 and projected on the working machine table 3 The indicator line 25 has only a short length, which may be sufficient for sawing workpieces of general width, but for a large workpiece 200, the length of the indicator line 25 cannot be extended to cover the entire range of the entire workpiece 200, which will affect the indicator line 25. The alignment and calibration work with the ink line of the workpiece 200 may cause errors in the size of the cut workpiece 200 .
