Description

Technical Field

[0001] The utility model relates to the technical field of machine tools, in particular to a profile cutting machine tool. Background Art

[0002] Profile cutting machine is a kind of mechanical equipment specially used for cutting metal profiles, which is widely used in the fields of construction, bridges, automobile manufacturing, etc. It is mainly used to cut metal profiles of various shapes, such as angle steel, channel steel, I-beam, pipe, etc., to meet the processing needs of different industries. The working principle of profile cutting machine is to cut or cut metal profiles through tools. Profile cutting machine often uses drilling tools, turning tools, cutting wheels and other tools to achieve the purpose of removing and cutting materials. Among them, grinding wheels are one of the most commonly used cutting and grinding tools and are widely used in profile cutting machines. However, grinding wheels often have wear problems during use, and when the machine tool robot arm is deformed or offset, it will cause aggravated wear and reduce the service life of the grinding wheel. Grinding wheel wear will lead to a decrease in the cutting ability of the machine tool, and the poor cutting of the product will increase significantly. In severe cases, it may cause the grinding wheel to break, thereby damaging the machine tool and even endangering the personal safety of the operator. However, the degree of wear of the grinding wheel is difficult to judge directly by the naked eye. Traditional technologies often require operators to approach or touch the grinding wheel and the mechanical arm to observe and detect the degree of wear of the grinding wheel. This measurement method may bring personal safety risks to operators and pose safety hazards. Therefore, the field of profile cutting machine tools urgently needs a technical solution that can safely and quickly monitor the deviation of the mechanical arm of the machine tool and the degree of wear of the grinding wheel.

If the laser emitted by the first laser emitter 8 passes through the detection hole 9 smoothly, the mechanical arm 5 is not obviously offset. At the same time, the device is also provided with a second laser emitter 10, and the sliding vertical rod 11, the scale pointer 1201 and the scale slot 12 are arranged below the second laser emitter 10.

[0031] Specifically, a first rack 22 is provided on the lower surface of the transmitter slot 18, and the upper surface of the transmitter slot 18 is set to a smooth plane. The connection between the second laser emitter 10 and the transmitter slot 18 is provided with teeth that cooperate with the first rack 22 structure. A first knob 23 is provided on the side of the second laser emitter 10 away from the robotic arm 5. The first knob 23 is fixedly connected to the second laser emitter 10.

[0034] Example 2

[0035] See attached Figure 1-5 The difference between this embodiment and embodiment 1 is that the up-and-down motion module 29 is configured as a U-shaped structure, and a shading plate 31 is provided on the side of the up-and-down motion module 29 away from the emitter support frame 7, and the lower end of the shading plate 31 is fixedly connected to the machine tool body 1, and the lasers emitted by the first laser emitter 8 and the second laser emitter 10 pass through the middle of the up-and-down motion module 29 and are projected onto the shading plate 31. The operator can judge the detection and monitoring results through the light spot on the shading plate 31, making detection and monitoring more convenient.

[0036] Specifically, a laser receiving screen 32 is provided on the shading plate 31, and the lasers emitted by the first laser emitter 8 and the second laser emitter 10 are projected onto the laser receiving screen 32.

When the wear degree of the grinding wheel 13 is detected, the controller 3 controls the grinding wheel 13 fixing seat 4 to rotate slowly. If the outer edge of the grinding wheel 13 is rough and uneven, the light spot on the laser receiving screen 32 changes continuously and is recorded, and the roughness of the outer edge of the grinding wheel 13 can be detected. If the mechanical arm 5 is offset, the light beam emitted by the first laser emitter 8 cannot pass through the detection hole 9. The controller 3 controls the movement of the front-back motion module 27, the left-right motion module 28, the up-down motion module 29 and the rotation module 30 to align the detection hole 9 with the light beam emitted by the first laser emitter 8 and record the movement of the mechanical arm 5, so as to record and calibrate the offset of the mechanical arm 5.

Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
