Description

Technical Field

[0001] The utility model relates to the field of laser cutting machines, in particular to a positioning component for laser cutting machines. Background Art

[0002] The laser cutting machine focuses the laser emitted from the laser into a high-power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach the melting point or boiling point. At the same time, the high-pressure gas coaxial with the beam blows away the molten or vaporized metal.

[0003] Patent CN220093443U proposes "a positioning component for a laser cutting machine", which adds the functionality of rapid positioning, so that it has the effect of positioning the workbench of the laser cutting machine, preventing the laser cutting machine from having poor positioning performance after the work is completed, and solving the problem of poor positioning performance of the laser cutting machine after the work is completed. However, the comparison document cannot fix the workpiece, which may easily cause defects in the workpiece welding. Utility Model Content

[0006] As a further solution of the utility model: a cooling mechanism is arranged on the side of the welding machine body, and the cooling mechanism includes a support plate fixed on the top of the base, a motor is installed on the outer side of the support plate through a support rod, a water bucket is fixed on the side of the welding machine body, a first gear is fixed on the output end of the motor, a connecting inclined groove is arranged on the back of the first gear, a pressure plate is slidably connected to the inside of the water bucket, a vertical rod is fixed to the bottom of the pressure plate, and an insert is fixed to the bottom of the vertical rod.

[0007] As a further solution of the utility model: a connecting rod is fixed to one end of the threaded rod and is rotatably connected to the disc through the connecting rod.

[0008] As a further solution of the utility model: the water bucket can store water for cooling.

[0009] As a further solution of the utility model: the insert block is located inside the inclined slot.

[0010] As a further solution of the utility model: a feed port is arranged on the top of the water bucket, and the feed port is opened or closed by a solenoid valve.

[0011] As a further solution of the utility model: a shock absorbing plate is arranged at the bottom of the base.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. Place the workpiece to be welded on the top of the base at the bottom of the pressing block, and then use the handle to drive the threaded rod to rotate, and then the threaded rod moves on the top of the support seat. When the threaded rod moves, the pressing block is driven to rotate through the connecting rod, and then one end of the pressing block is rotated downward to press the workpiece to achieve positioning, which is helpful to prevent the workpiece from offsetting and causing defects during welding;

[0014] 2. Pour water into the bucket from the feed port, and then put the nitrate block in. The nitrate block will then remain on the top of the pressing plate. Start the motor to drive the first gear to rotate. Since the plug block is located inside the chute, the chute will rotate when the first gear rotates. The plug block will then drive the vertical rod and the pressing plate to rise and fall. When the pressing plate rises and falls, the nitrate block will be crushed and then fall from the leak hole. Crushing the nitrate block helps to reduce the volume and shorten the time it takes to dissolve in water. The lifting of the pressing plate stirs the water, which then causes the nitrate to quickly dissolve in the water. The nitrate dissolved in the water absorbs a large amount of heat to form cooling water, which is then discharged through the drain pipe into the cavity of the welding head to cool the welding head.
