Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary positioning, and particularly relates to an auxiliary positioning device for a laser cutting robot. Background Technique

[0002] The auxiliary positioning device of a laser cutting robot is one of the key technologies for improving cutting accuracy and efficiency. In industrial automation, laser cutting robots are usually used for precise cutting of various materials, such as metal sheets, plastic sheets, etc. Since the cutting process requires highly precise positioning and control, especially in large-scale production, traditional manual positioning methods may not meet the requirements of accuracy and efficiency.

[0003] The patent with the patent announcement number CN215393289U discloses an auxiliary positioning device for a laser cutting robot, including a base. The lower end of the base is fixedly connected to two support plates. A lead screw is rotatably connected to the side walls of the two support plates. One of the support plate side walls is fixedly connected to a first motor, and the movable end of the first motor is fixedly connected to one end of the lead screw. The utility model drives the lead screw to rotate by rotating the first motor, and then drives the slider to slide in the horizontal direction, and then drives the article to move in the horizontal direction. The second motor rotates to drive the U-shaped plate to rotate, and then drives the article to rotate. At the same time, the telescopic electric push rod is adjusted, and then drives the U-shaped plate to rotate up and down, and then adjusts the angle of the article. Therefore, this device can not only adjust the cutting position of the article, but also adjust the cutting angle of the article, without repeatedly positioning and cutting the article, reducing the labor intensity and accelerating the cutting efficiency.

[0004] However, the current auxiliary positioning device has the following problems: when the auxiliary positioning device clamps and fixes objects made of special materials such as plastics, excessive clamping will cause deformation or damage to the surface or structure of the workpiece. Therefore, we propose an auxiliary positioning device for a laser cutting robot. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an auxiliary positioning device for a laser cutting robot, which can solve the problem that when the auxiliary positioning device clamps and fixes objects made of special materials such as plastics in the related technology, excessive clamping will cause deformation or damage to the surface or structure of the workpiece.

[0006] The technical solution adopted by the utility model is specifically as follows:

[0007] An auxiliary positioning device for a laser cutting robot, comprising a base. A moving device is arranged on the inner wall of the base. A rotating device is arranged on the top of the moving device. An anti-pinch device is arranged on the top of the rotating device. The anti-pinch device includes an outer plate, which is fixedly connected to the top of the rotating device. A rotating rod is threadedly connected to the side of the outer plate. One end of the rotating rod is fixedly connected to a turntable. The end of the rotating rod away from the turntable is rotatably connected to a clamping plate. A friction plate is slidably connected to the side of the clamping plate. A hinge rod is hinged to the side of the friction plate. The end of the hinge rod away from the friction plate is hinged to a protective plate. A spring is arranged between the clamping plate and the protective plate. A friction strip is fixedly connected to the bottom of the inner wall of the outer plate.

[0008] A groove for placing the friction strip is arranged at the bottom of the inner wall of the outer plate, and the friction strip is located on the movement track of the friction plate.

[0009] The protective plate is smaller than the clamping plate, and a gap is arranged between the protective plate and the clamping plate.

[0010] A high-temperature prevention device is arranged on the top of the base. The high-temperature prevention device includes a liquid storage tank, which is fixedly connected to the top of the base. An input pipe is fixedly connected to the top of the liquid storage tank. An output pipe is fixedly connected to the side of the liquid storage tank. One end of the output pipe away from the liquid storage tank is fixedly connected to a spray head. A resisting plate is fixedly connected to the side of the clamping plate. A resisting rod is fixedly connected to the side of the clamping plate. A pressing member is fixedly connected to the side of the liquid storage tank, and the pressing member is used to control the lubricating liquid in the liquid storage tank to be sprayed out through the spray head.

[0011] The spray head and the resisting plate are on the same horizontal plane, and the spray port of the spray head is located on the displacement track of the resisting plate.

[0012] The resisting rod is located below the resisting plate, and the pressing member is located on the movement track of the resisting rod.

[0013] The technical effects achieved by the present utility model are as follows:

[0014] Through the setting of the anti-pinch device of the present utility model, the cooperation of the moving disk, the rotating rod, the clamping plate, the spring, the protective plate, the hinge rod, the friction plate and the friction strip enables the friction plate to generate friction force when it touches the friction strip. The increase in the friction force will prevent the clamping plate from continuing to push inward, thereby preventing excessive clamping from damaging objects made of special materials such as plastics and achieving a protective effect.

[0015] Through the setting of the high-temperature prevention device, the cooperation of the clamping plate, the resisting rod, the pressing member, the nozzle, the liquid storage tank, the output pipe, and the resisting plate enables the pressing member to control the lubricating liquid in the liquid storage tank to be ejected through the nozzle along the output pipe, effectively reducing the frictional heat generated during high-speed cutting, reducing the frictional resistance during cutting, and thus improving the cutting efficiency; the movement of the resisting plate will limit the spraying range of the nozzle, preventing the problem of waste of lubricating liquid.

SPECIFIC EMBODIMENTS

[0023] In order to make the purpose and advantages of the present utility model clearer, the following describes the present utility model in detail with reference to the embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present utility model, and does not strictly limit the specific protection scope claimed by the present utility model.

[0024] Such as Figures 1-5As shown in the figure, an auxiliary positioning device for a laser cutting robot includes a base 1. A moving device 4 is provided on the inner wall of the base 1. A rotating device 5 is provided on the top of the moving device 4. The moving device 4 can drive the rotating device 5 to move. A pinch prevention device 2 is provided on the top of the rotating device 5. The pinch prevention device 2 includes an outer plate 21. The outer plate 21 is fixedly connected to the top of the rotating device 5. The rotating device 5 can drive the outer plate 21 to rotate. A rotating rod 22 is threadedly connected to the side of the outer plate 21. The outer wall of the rotating rod 22 is threaded. One end of the rotating rod 22 is fixedly connected to a turntable 23. The end of the rotating rod 22 away from the turntable 23 is rotatably connected to a clamping plate 24. The movement of the clamping plate 24 drives a protection plate 27 to move inward through a spring 28. A friction plate 25 is slidably connected to the side of the clamping plate 24. An articulated rod 26 is articulated to the side of the friction plate 25. One end of the articulated rod 26 away from the friction plate 25 is articulated to a protection plate 27. A spring 28 is provided between the clamping plate 24 and the protection plate 27. The spring 28 can push the protection plate 27 to move inward through its own elastic force. A friction strip 29 is fixedly connected to the bottom of the inner wall of the outer plate 21. When the friction plate 25 abuts against the friction strip 29, friction is generated, and the increase in friction will prevent the clamping plate 24 from continuing to move inward.

[0025] A groove for placing the friction strip 29 is provided at the bottom of the inner wall of the outer plate 21. The friction strip 29 is located on the movement track of the friction plate 25.

[0026] The protection plate 27 is smaller than the clamping plate 24. A gap is provided between the protection plate 27 and the clamping plate 24. The protection plate 27 is located on the movement track of the inner wall of the clamping plate 24.

[0027] According to the above structure, the worker rotates the turntable 23 to make the rotating rod 22 rotate. The rotation of the rotating rod 22 drives the clamping plate 24 to move inward. The movement of the clamping plate 24 drives the protection plate 27 to move inward through the spring 28. When the protection plate 27 abuts against the object to be clamped, the protection plate 27 drives the friction plate 25 to move downward through the articulated rod 26. When the friction plate 25 abuts against the friction strip 29, friction is generated, and the increase in friction will prevent the clamping plate 24 from continuing to move inward, thereby preventing excessive clamping from damaging objects made of special materials such as plastics and achieving a protective effect.

[0028] Such as Figures 1-5As shown in the figure, an auxiliary positioning device for a laser cutting robot includes a high-temperature protection device 3 disposed on the top of a base 1. The high-temperature protection device 3 includes a liquid storage tank 31 fixedly connected to the top of the base 1. An input pipe 32 is fixedly connected to the top of the liquid storage tank 31, and an output pipe 33 is fixedly connected to the side of the liquid storage tank 31. The output pipe 33 is bent. One end of the output pipe 33 away from the liquid storage tank 31 is fixedly connected to a nozzle 34, and the nozzle 34 is strip-shaped. A resisting plate 35 is fixedly connected to the side of a clamping plate 24, and a resisting rod 36 is fixedly connected to the side of the clamping plate 24. A pressing member 37 is fixedly connected to the side of the liquid storage tank 31. The pressing member 37 is used to control the lubricating liquid in the liquid storage tank 31 to be sprayed out through the nozzle 34. The working principle of the pressing member 37 is similar to that of a spray bottle. The pressing member 37 is composed of a pressing part and a spring pump, and thus is reset by the elastic force of the spring pump.

[0029] The nozzle 34 and the resisting plate 35 are on the same horizontal plane. A plurality of small holes are provided at the inner wall nozzle of the nozzle 34, and the nozzle of the nozzle 34 is located on the displacement track of the resisting plate 35.

[0030] The resisting rod 36 is located below the resisting plate 35, and the pressing member 37 is located on the movement track of the resisting rod 36.

[0031] According to the above structure, when the clamping plate 24 moves inward, it drives the resisting rod 36 to move. The resisting rod 36 touches the pressing member 37, and the pressing member 37 controls the lubricating liquid in the liquid storage tank 31 to be sprayed out through the output pipe 33 and the nozzle 34, effectively reducing the frictional heat generated during high-speed cutting, reducing the frictional resistance during cutting, and thus improving the cutting efficiency; when the clamping plate 24 moves inward, it drives the resisting plate 35 to move, and the movement of the resisting plate 35 restricts the spraying range of the nozzle 34, avoiding the problem of excessive spraying of the lubricating liquid and resulting in waste.

[0032] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and retouches can be made, and these improvements and retouches should also be regarded as the protection scope of the present invention.
