Description

Technical Field

[0001] The invention relates to a laser hole opening device. Background Art

[0002] Laser cutting is a process in which a horizontal laser beam emitted by a laser is transformed into a vertical downward laser beam through a 45° total reflection mirror, and then focused by a lens to form a very small light spot at the focal point. When the light spot is irradiated on the material, the material is quickly heated to the vaporization temperature and evaporates to form holes. As the light beam moves over the material and auxiliary gases (carbon dioxide, oxygen, nitrogen, etc.) are used to blow away the molten waste, the holes are continuously formed into a very narrow (such as about 0.1mm) cut, completing the cutting of the material.

[0003] In the prior art, laser cutting equipment is mainly divided into two types: fixed equipment and mobile equipment. Fixed equipment uses multi-axis drive and can complete precise position drilling. It is mainly used for mass production and large-scale drilling needs.

[0039] See also Figure 8 and Fig. 9 As shown, the main plate is A and the cut waste is B.

[0040] The steps are as follows:

[0041] The device is pushed to the side or surface of the metal plate to be perforated, so that the vertical lifting device 5 corresponds to the center position of the hole to be perforated.

[0042] The rotating device 6 adjusts the laser cutting head 2 to the circumferential position required for cutting. After the laser cutting head 2 moves into place, the vertical lifting device 5 moves downward to be fixed with the main plate A. The main machine 1 drives the laser cutting head 2 to emit a laser. The rotating device 6 rotates at a constant speed along the vertical lifting device 5, driving the laser cutting head 2 to rotate 361 to 365 degrees, so that there is no connection point between the waste B and the main plate A. After the cutting is completed, the laser cutting head 2 moves upward and moves outward to separate from the top of the waste B. At this time, the vertical lifting device 5 absorbs the separated waste B, lifts the waste B upward and separates it from the main plate A, uses a cart or other tools to move it to the bottom of the waste B, and then releases the waste B, completing the waste material removal work.

[0050] The counterweight block 9 is provided to increase the stability of the support device 4, so that the movement of the laser cutting head 2 is more stable and the cutting edge of the obtained hole is smoother.

[0051] See also Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the vertical lifting device 5 includes an electric push rod 51, a fixed cylinder 52, a movable cylinder 53 and a vacuum pump 54.

[0052] In the above technical solution, the movable cylinder 53 is controlled by the electric push rod 51 to move downward along the fixed cylinder 52 until the negative pressure suction cup 56 is adsorbed on the surface of the main plate A. At this time, the air in the negative pressure suction cup 56 is extracted by the vacuum pump 54, so that the negative pressure suction cup 56 is adsorbed and fixed to the main plate A, which plays a role in centering and fixing.

[0053] When the laser cutting head 2 rotates around the fixed cylinder 52 for one circle, the cutting is completed. At this time, the cut waste B is separated.

[0058] In the above technical solution, the rotation of the screw drives the slide 68 to move, thereby completing the position adjustment of the laser cutting head 2, so that the laser emitting end of the laser cutting head 2 is located at the circumferential position of the hole to be cut.

[0059] After the cutting is completed, the laser cutting head 2 moves outward and away from the position of the hole, so as to facilitate the upward removal of the waste.

A slide cylinder 613 is slidably matched through the stepped hole 612. The bottom of the slide cylinder 613 is connected to the laser cutting head 2. The top of the slide cylinder 613 is threadedly connected to a limiting ring 614. The limiting ring 614 limits the downward movement of the slide cylinder 613.

[0065] The cable 3 for supplying power to the laser cutting head 2 passes through the axis of the slide cylinder 613, thereby avoiding interference with components such as the screw.

Both ends of the sleeve 9 are fixed to the bracket device 4, and the cable 3 passes through the sleeve 9.

[0067] In the above technical solution, an elastic sleeve 9 is used. When the outer bracket 62 rotates one circle, the cable 3 will be pulled out, and the cable 3 will interfere with the sleeve 9. Therefore, an elastically deformable sleeve 9 is used. When position interference occurs, the position is retreated through the elastic deformation of the sleeve 9, so that the laser cutting head 2 can complete a position movement of more than 360 degrees.

A pulley 77 is provided, and the cable 3 enters from the top of the box body 71, passes around the pulley 77 and then passes out from the top of the box body 71. When the slide seat 68 moves in the direction away from the fixed cylinder 52, the cable 3 is pulled out. At this time, the pulley 77 moves upward after being subjected to force, providing the cable 3 with a margin for being pulled out. When the slide seat 68 moves toward the direction of the fixed cylinder 52, the pulley 77 moves downward under the action of the spring 76 to adapt to the retraction of the cable 3.

[0069] The function of the wire pulling device 7 is to maintain the tension on the cable 3 as much as possible, so as to prevent the cable 3 from being in contact with and worn by other running parts in the device after being loosely hung.
