[0002] Cutting refers to the process of using cutting tools (including cutting tools, grinding tools and abrasives) to cut off the excess material layer on the blank or workpiece into chips, so that the workpiece can obtain the specified geometric shape, size and surface quality. The workpiece refers to the object to be processed during the machining process. It can be a single part or a combination of several parts fixed together. There are various types of workpiece processing methods, including turning, milling, planing, grinding, casting, forging, etc. The processing procedures of the workpiece also change with the change of the processing method.

[0003] A positioning device for cutting electrical cabinet steel disclosed in the Chinese utility model patent application publication specification CN 204171701 U relates to the field of electrical cabinet production equipment, and includes a cutting knife, a workpiece mounting plate is arranged below the cutting knife, a clamping mechanism is arranged at one end of the workpiece mounting plate, a control rod is connected to the other end of the workpiece mounting plate, a handle is arranged at the end of the control rod, the middle of the workpiece mounting plate is mounted on a support through a rotating shaft, and the lower end of the support is fixed on a base. The positioning device for cutting electrical cabinet steel provided by the utility model has a reasonable structural design, is suitable for positioning and processing electrical cabinet support skeleton steel, is convenient for workpiece clamping, is convenient for controlling the distance between the workpiece and the cutting knife, and is safe to use.

[0004] However, this positioning technology requires manual adjustment of the joystick and handle to fix the workpiece, and then use a cutting knife to cut the workpiece, which is labor-intensive and has low cutting accuracy. It is not convenient to cut the details of the workpiece. Since laser cutting easily generates a lot of heat, excessive temperature can cause the workpiece to crack, reduce the yield rate, and increase raw material loss. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The positioning structure for circular workpiece cutting is provided with a bottom plate, an adjustment module, a carbon dioxide laser, an air chamber and a nozzle. During the cutting process, the nozzle irradiates the laser beam generated by the carbon dioxide laser onto the surface of the cutting material, generating an extremely high temperature, causing the surface of the material to evaporate or melt rapidly, and forming a tiny slit on the material to achieve the purpose of cutting. The laser cutting speed is fast, the incision is narrow and parallel, and the cutting accuracy is high.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-Figure 4 As shown, a technical solution provided by the utility model:

[0024] A positioning structure for cutting a circular workpiece, comprising a bearing base 01, one end of the upper side of the bearing base 01 is fixedly connected to a fixing base 02, one end of the fixing base 02 is fixedly connected to a rotating motor 03, one end of the rotating motor 03 is fixedly connected to a power switch, and the other end of the upper side of the bearing base 01 is fixedly connected to a hydraulic press 07. When in use, the cutting material is pressed by the hydraulic press 07, and the power supply of the rotating motor 03 is started to complete the rotary cutting of the cutting material, thereby replacing manual precise positioning and cutting of the workpiece, improving cutting efficiency, and reducing production costs;

[0025] The bottom of the supporting base 01 is fixedly connected with anti-skid support feet around it. When the circular workpiece is being cut, it can prevent the rotating motor 03 from vibrating when it is working, causing the entire supporting base 01 to be displaced due to vibration, which is not conducive to the precise positioning and cutting of the workpiece.

[0026] Preferably, connecting grooves 04 are provided at both ends of the upper side of the supporting base 01, one end of the connecting groove 04 is fixedly connected to a push rod motor 05, and one end of the push rod motor 05 is fixedly connected to a moving seat 06. When in use, the push rod motor 05 can complete reciprocating motion along a straight line after being started, driving the moving seat 06 to complete displacement, thereby completing the cutting of circular workpieces of different sizes and thicknesses.

[0027] Preferably, both sides of the supporting base 01 are slidably connected with a moving base 06, one end of the moving base 06 is rotatably connected with a bottom plate 15, one end of the upper side of the bottom plate 15 is fixedly connected with an adjusting module 14, one end of the adjusting module 14 is fixedly connected with a carbon dioxide laser 12, one end of the carbon dioxide laser 12 is fixedly connected with an air chamber 16, and one end of the air chamber 16 is fixedly connected with a nozzle 17. During the cutting process, the nozzle 17 generates a laser beam to irradiate the surface of the cutting material, generating an extremely high temperature, causing the surface of the material to evaporate or melt rapidly, and forming a tiny slit on the material to achieve the purpose of cutting. The laser cutting speed is fast, the incisions are narrow and parallel, and the cutting accuracy is high. The adjusting module 14 can adjust the angle of the laser cutting, which is convenient for fine-tuning the cutting details.

[0028] Preferably, a movable groove is provided at the bottom of the supporting base 01, and the inside of the movable groove is slidably connected to the movable seat 06. The other end of the movable seat 06 is fixedly connected to a coolant pipe 11, and one end of the coolant pipe 11 is fixedly connected to a nozzle 10. Since a large amount of heat is easily generated during laser cutting, excessive temperature will affect the stability and life of the equipment. It is necessary to cool the workpiece in time to prevent the workpiece from cracking due to a rapid increase in temperature. The nozzle 17 can spray the coolant evenly and stably on the surface of the workpiece to prevent the nozzle 17 from being abnormal or damaged due to high temperature generated by long-term cutting.

[0029] Preferably, one end of the hydraulic press 07 is rotatably connected to a rotating seat 19, and one end of the rotating seat 19 is fixedly connected to a first clamping member 08. A socket is provided inside the first clamping member 08. When in use, after the raw material is clamped, the rotating motor 03 is started to drive the clamped raw material and the rotating seat 19 rotatably connected to the hydraulic press 07 to rotate synchronously.

[0030] Preferably, the other end of the rotating motor 03 is fixedly connected to a rotating rod, one end of the rotating rod is fixedly connected to a second clamping member 09, and one side of the second clamping member 09 is fixedly connected to a plug-in 20 that matches the internal socket of the first clamping member 08. When in use, the cutting material is inserted into the side where the first clamping member 08 and the second clamping member 09 are connected, and the first clamping member 08, the second clamping member 09 and the cutting material are pressed together by the hydraulic press 07, thereby preventing the workpiece from falling off during high-speed rotation and avoiding damage to the equipment.

[0031] When a positioning structure for cutting a circular workpiece in this embodiment is in use, the cutting material is pressed by the hydraulic press 07, and the power supply of the rotating motor 03 is started to make the cutting material complete the rotational cutting, thereby replacing manual precise positioning and cutting of the workpiece, improving cutting efficiency, and reducing production costs. When the circular workpiece is being cut, it can prevent the rotating motor 03 from vibrating during operation, causing the overall supporting base 01 to be displaced due to vibration, which is not conducive to the precise positioning and cutting of the workpiece.
