Description

Technical Field

[0001] The present application relates to the field of laser cutting, and in particular to a laser cutting device for sheet metal workpieces. Background Art

[0002] Laser cutting uses a focusing mirror to focus a CO2 laser beam on the surface of the material to melt the material, and at the same time uses compressed gas coaxial with the laser beam to blow away the melted material, and makes the laser beam and the material move relative to each other along a certain trajectory, thereby forming a certain shape of the cut. Laser cutting technology is widely used in the processing of metal and non-metal materials.

[0003] The patent document with announcement number CN217071127U discloses a laser cutting device for sheet metal parts. The utility model discloses a laser cutting device for sheet metal parts, which belongs to the field of laser cutting technology. Its technical points are: it includes a sliding component, which is installed on the machine body and connected to a laser head at the end; a clamping component, which is installed on the cutting table; and a limit component, which is connected to the clamping component. In the above application document, when fixing the sheet metal parts, the sheet metal parts are placed on the cutting table and the clamping component is rotated so that the clamping component can clamp and fix the sheet metal parts.

[0020] In order to enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0021] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0022] Example 1

[0023] See also Figures 1-4The present embodiment provides a laser cutting device for sheet metal workpieces, comprising a base plate 1, a clamping assembly 2 is provided above the base plate 1, the clamping assembly 2 comprises a second support plate 201, the second support plate 201 is fixedly connected to the top of the base plate 1, an electric push rod 202 is fixedly connected to the left side of the second support plate 201, the left end of the electric push rod 202 is rotatably connected to the second clamping plate 203, a holding assembly 3 is provided on the left side of the clamping assembly 2, the holding assembly 3 comprises a first support plate 301, a first holding assembly 302, and a second holding assembly 303. The support plate 301 is fixedly connected to the top of the bottom plate 1, and a rotating rod 302 is passed through the right side of the first support plate 301 and is rotatably connected. The right end of the rotating rod 302 is fixedly connected to the first clamping plate 303, and the left end of the rotating rod 302 is fixedly connected to the chuck 304. Four slots are provided on the chuck 304. A limit assembly 4 is provided below the chuck 304. The limit assembly 4 includes a card strip 401. A semicircular protrusion is provided on the card strip 401 for clamping into the slot on the chuck 304. The card strip 401 is connected to the chuck 304. 04 is clamped at the bottom, and the card strip 401 is rotated and elastically connected to the left side of the first support plate 301 through the torsion spring 402. Under normal conditions, the torsion spring 402 will apply torque to press the card strip 401 to the bottom of the chuck 304. A fixing component 7 is provided under the card strip 401, and a driving component 5 is provided on the left side of the chuck 304. A cutting component 6 is provided above the base plate 1. The cutting component 6 includes a support frame 601. The support frame 601 is shaped like a door frame. The left side of the inner surface of the support frame 601 is fixedly connected to the left side of the motor 501. The support frame 601 is fixedly connected to the top of the base plate 1. The top of the inner surface of the support frame 601 is fixedly connected with an electric slide rail 602, and a sliding seat 603 is slidably connected to the bottom of the electric slide rail 602. The electric slide rail 602 can drive the sliding seat 603 to slide, which is a prior art. A cutting device 604 is fixedly installed under the sliding seat 603. The cutting device 604 is specifically a laser head of a laser cutting machine for cutting sheet metal parts, which is a prior art.

[0024] When the above device is used, the sheet metal part is first placed between the second clamping plate 203 and the first clamping plate 303, and then the electric push rod 202 is started to drive the second clamping plate 203 to move toward the first clamping plate 303, thereby clamping the sheet metal part. At this time, the electric slide rail 602 drives the sliding seat 603 to move the cutting device 604 to accurately cut the sheet metal part. When it is necessary to cut other surfaces of the sheet metal part, the rotating rod 302 drives the first clamping plate 303 to rotate so that the sheet metal part is brought into contact with the workpiece. The second clamping plate 203 is driven to rotate on the electric push rod 202. When the rotating rod 302 rotates, the chuck 304 is driven to rotate, and the clamping strip 401 slides out of the slot on the chuck 304. When the next slot moves to the clamping strip 401 as the chuck 304 rotates, the torsion spring 402 applies a torsional force to pressurize the clamping strip 401 toward the bottom of the chuck 304, so that the clamping strip 401 is clamped into the slot on the chuck 304, thereby limiting the chuck 304 to facilitate the steering of the clamped sheet metal.

[0025] Example 2

[0026] See also Figures 1-4 On the basis of the first embodiment, the fixing assembly 7 includes a hydraulic push rod 701, which is fixedly connected to the top of the base plate 1. The upper end of the hydraulic push rod 701 is fixedly connected to a head 702, and the head 702 is made of rubber. The driving assembly 5 includes a motor 501, and the output end of the motor 501 faces to the right. The output end of the motor 501 is fixedly connected to a rotating shaft 502 through a coupling, and the rotating shaft 502 is fixedly connected to the left side of the chuck 304.

[0027] When the above-mentioned equipment is used in practice, when it is necessary to rotate the clamped sheet metal, the motor 501 is started to drive the rotating shaft 502 to rotate. The rotation of the rotating shaft 502 will drive the chuck 304 to rotate the rotating rod 302, and then drive the first clamping plate 303 to rotate so that the sheet metal drives the second clamping plate 203 to rotate on the electric push rod 202. When it needs to be fixed after the rotation is completed, the hydraulic push rod 701 is started to make the head 702 rise, and the head 702 will support the card strip 401, so that the card strip 401 firmly locks the card slot on the chuck 304. At this time, the chuck 304 cannot rotate, and the rotating rod 302 and the first clamping plate 303 cannot drive the sheet metal to rotate, thereby achieving the fixing effect of the sheet metal.

[0028] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
