Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting equipment, and specifically relates to a portable laser cutting equipment. Background Technique

[0002] Laser cutting is to focus the laser emitted from the laser into a laser beam through an 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 melted or vaporized metal. As the relative position of the beam and the workpiece moves, the purpose of cutting is achieved, and it is widely used in the processing of metal workpieces;

[0003] The existing portable laser cutting equipment, such as a portable laser cutting machine with the publication number CN216264119U, includes a cutting machine main body. A pressing plate is arranged at the bottom of the cutting machine main body. A laser emitter is arranged at the front end of the lower end surface of the cutting machine main body. A protective plate is sleeved on the upper end of the laser emitter. A handle is arranged at the upper end of the cutting machine main body. A switch is arranged at the lower end of the handle. An air inlet is arranged on the front end surface of the cutting machine main body. An exhaust duct is arranged on the back surface of the cutting machine main body. A blower is arranged inside the cutting machine main body. An observation device is arranged on the side end surface of the cutting machine main body. The observation device consists of a suspension rod, a mounting bracket, a reflecting mirror and a wing nut. The reflecting mirror is installed on the mounting bracket, and the mounting bracket is installed at the lower end of the suspension rod. The present invention improves the cutting accuracy of the cutting machine by arranging an observation device on the side end surface of the cutting machine main body, which is convenient to observe the cutting point of the cutting machine through the reflecting mirror;

[0004] In the actual use process of the above-mentioned existing portable laser cutting equipment, since the cutting equipment needs to be held manually for cutting, when straight-line cutting is required, the existing portable laser cutting equipment lacks a guiding and positioning mechanism, resulting in difficulty in ensuring straight cutting during manual cutting, thereby affecting the processing progress of the workpiece. Summary of the Invention

[0005] The purpose of the present invention is to provide a portable laser cutting equipment to solve the problems raised in the above background technique.

One end of the limiting frame is fixedly connected to one end of the first spring, and the other end of the first spring is fixed on the movable frame.

[0007] Preferably, a wire bundling frame is fixed on the front side of the electric control chassis, and a heat dissipation port is arranged on the left side of the electric control chassis. The wire bundling frame can facilitate the storage and limitation of wires.

[0008] Preferably, a handle is fixed on the upper end surface of the cutting host, and a control switch is installed on the handle. Rollable balls are installed on the lower end surface of the cutting host, and a controller is also installed on the cutting host. Through the rolling action of the balls, the friction between the cutting host and the workpiece can be reduced, facilitating the movement of the cutting host.

[0009] Preferably, the cutting mechanism includes an electric telescopic rod, which is electrically connected to the controller. The electric telescopic rod is fixed inside the cutting host, and the output end of the electric telescopic rod is fixedly connected to a movable plate. A positioning shaft is fixed on the movable plate, and the positioning shaft is engaged with the circular hole on the circular plate to achieve positioning. Through the action of the electric telescopic rod, a basic acting force can be provided for the movement of the movable plate and the positioning shaft. With the engagement and positioning between the positioning shaft and the circular hole on the circular plate, the anti-misoperation effect can be achieved.

[0010] Preferably, a cross bar is fixed on the left side of the movable plate, and the cross bar is slidably connected to a partition plate, and the partition plate is fixed inside the cutting host. When the movable plate moves, with the sliding guiding action between the cross bar and the partition plate, the stability of the movement of the movable plate can be ensured.

[0011] Preferably, a mounting plate is fixed on the cross bar, and a laser cutting head is fixed on the lower end surface of the mounting plate. The laser cutting head is connected to the electric control chassis through a wire, and the laser cutting head is electrically connected to the control switch. A baffle is fixed on the left side of the mounting plate, and rubber pads are symmetrically fixed on the upper and lower sides of the baffle. Through the action of the baffle, after the device is used, the laser cutting head can be shielded and protected to prevent the staff from being accidentally touched and scalded.

[0012] Preferably, a first magnet is fixed on one side of the scale rod close to the cutting host, and a magnetic attraction structure is formed between the first magnet and a third magnet fixed on the cutting host. A second magnet is fixed on the other side of the scale rod away from the cutting host, and a magnetic attraction structure is formed between the second magnet and a fourth magnet fixed on the cutting host.

[0013] Preferably, the limiting mechanism includes a connecting frame. One end of the connecting frame is fixedly connected to the circular plate, and the connecting frame is slidably connected to the cutting host. The other end of the connecting frame is fixedly connected to the movable ring. A ball shaft is nested and slidably connected to the movable ring. The ball shaft is slidably connected to the scale rod, and the ball shaft is fixed on the limiting rack. The limiting rack is slidably connected to the scale rod. At the same time, the limiting rack is engaged with the limiting tooth block to achieve the positioning function.

[0014] Preferably, a fixed frame is also fixed on the movable ring, and a clamping block is fixed on the fixed frame. The clamping block is nested with the lower opening of the rotating shaft to achieve positioning. Through the nesting and positioning of the clamping block and the lower opening of the rotating shaft, the rotating shaft can be locked to prevent the rotating shaft from rotating during the cutting process.

[0015] Preferably, the control mechanism includes a pull rod. The pull rod is slidably connected to the cutting host. A pressure rod is fixed at the upper end of the pull rod. The distance between the pressure rod and the control switch is 1 cm - 2 cm. At the same time, a circular plate is fixed on the pressure rod. A second spring is fixed between the circular plate and the cutting host. Through the above structure, the control and start-up function of the device can be realized. With the elastic action of the second spring, a basic acting force can be provided for the automatic reset of the pull rod.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. This portable laser cutting device adopts a foldable and retractable positioning and guiding mechanism. When cutting a workpiece, the cutting width can be controlled by adjusting the position of the limiting frame. The guiding and positioning are realized by the contact and sliding between the limiting frame and the side of the workpiece, so as to ensure the straightness of the cutting line, and then ensure the cutting accuracy, and effectively improve the convenience of device operation.

[0018] 2. This portable laser cutting device adopts a linkage self-locking mechanism. When the device starts to cut a workpiece, the positioning of the limiting frame can be realized by the engagement of the limiting rack and the limiting tooth block. The angular positioning of the scale rod can be realized by the nesting of the clamping block and the rotating shaft, avoiding the deviation of the limiting frame or the scale rod during the cutting process, thus effectively ensuring the stability during the operation of the device, and then effectively ensuring the cutting accuracy.

[0019] 3. The portable laser cutting device adopts a retractable cutting mechanism. After cutting is completed, it can achieve the storage and protection of the laser cutting head, avoiding the problem of workers being scalded by accidentally touching the laser cutting head. After the laser cutting head is stored, with the cooperation of the engagement between the positioning shaft and the circular plate, the positioning of the circular plate can be achieved, thereby realizing the self-locking of the pull rod, and further avoiding the accidental activation of the device and ensuring the safety of the device during use.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figures 1-7 , the present invention provides a technical solution: a portable laser cutting device, including an electric control chassis 1 and a cutting host 2. A cutting mechanism 3 is installed on the cutting host 2. Positioning mechanisms 4 are symmetrically installed on the front and back sides of the cutting host 2. A limiting mechanism 5 and a control mechanism 6 are also installed on the cutting host 2. The positioning mechanism 4 includes a rotating shaft 401, the rotating shaft 401 is connected to the cutting host 2 by bearings, a scale rod 402 is fixed at the upper end of the rotating shaft 401, a movable frame 407 is slidably connected to the scale rod 402, a limiting tooth block 408 is fixed on the movable frame 407, a limiting frame 409 is arranged on the lower side of the movable frame 407, and the lower end surface of the limiting frame 409 is lower than the lower end surface of the ball 203. Slide rods 410 are symmetrically fixed on the left and right sides of the limiting frame 409, and the slide rods 410 are slidably connected to the movable frame 407. The limiting frame 409 is fixed to one end of a first spring 411, and the other end of the first spring 411 is fixed to the movable frame 407.

[0030] A wire bundling frame 101 is fixed on the front side of the electric control chassis 1, and a heat dissipation port 102 is arranged on the left side of the electric control chassis 1; a handle 201 is fixed on the upper end surface of the cutting host 2, a control switch 202 is installed on the handle 201, rolling balls 203 are installed on the lower end surface of the cutting host 2, and a controller 204 is also installed on the cutting host 2;

[0031] When using this portable laser cutting device, as Figures 1-7As shown in the figure, first place the cutting host 2 on the workpiece to be cut, and rotate the scale rod 402 by 90°. At this time, the first magnet 403 is separated from the third magnet 405, and the second magnet 404 is adsorbed to the fourth magnet 406, so that the scale rod 402 is perpendicular to the cutting host 2. Then move the limit frame 409 to contact the edge of the workpiece. At this time, the first spring 411 is in a contracted state, so that there is a certain pressure between the limit frame 409 and the workpiece. Adjust the distance between the limit frame 409 and the laser cutting head 307 according to the width to be cut. With the sliding action between the movable frame 407 and the scale rod 402, the position adjustment of the limit frame 409 can be realized. Combined with the scale line on the scale rod 402, the distance between the limit frame 409 and the laser cutting head 307 can be determined, so as to realize the positioning adjustment. During the subsequent cutting process, through the sliding guiding action between the limit frame 409 and the edge of the workpiece, the guiding of the laser cutting head 307 can be realized, ensuring that the laser cutting head 307 moves in a straight line;

[0032] The cutting mechanism 3 includes an electric telescopic rod 301, which is electrically connected to the controller 204. The electric telescopic rod 301 is fixed in the cutting host 2, and the output end of the electric telescopic rod 301 is fixed to the movable plate 302. A positioning shaft 303 is fixed on the movable plate 302, and the positioning shaft 303 is engaged with the circular hole on the circular plate 603 to achieve positioning; a cross bar 304 is fixed on the left side of the movable plate 302, and the cross bar 304 is slidably connected to the partition plate 305, and the partition plate 305 is fixed in the cutting host 2; an installation plate 306 is fixed on the cross bar 304, and a laser cutting head 307 is fixed on the lower end surface of the installation plate 306. The laser cutting head 307 is connected to the electric control chassis 1 through a wire, and the laser cutting head 307 is electrically connected to the control switch 202. A baffle 308 is fixed on the left side of the installation plate 306, and rubber pads 309 are symmetrically fixed on the upper and lower sides of the baffle 308; a first magnet 403 is fixed on one side of the scale rod 402 close to the cutting host 2, and the first magnet 403 and the third magnet 405 fixed on the cutting host 2 form a magnetic attraction structure. A second magnet 404 is fixed on the side of the scale rod 402 far from the cutting host 2, and the second magnet 404 and the fourth magnet 406 fixed on the cutting host 2 form a magnetic attraction structure; the control mechanism 6 includes a pull rod 601, which is slidably connected to the cutting host 2. The upper end of the pull rod 601 is fixed with a pressure rod 602, and the distance between the pressure rod 602 and the control switch 202 is 1 cm - 2 cm. A circular plate 603 is fixed on the pressure rod 602, and a second spring 604 is fixed between the circular plate 603 and the cutting host 2;

[0033] After the cutting width adjustment is completed, when cutting, such as Figures 1-7As shown in the figure, at this time, the electric telescopic rod 301 is controlled by the controller 204 to extend, so as to drive the movable plate 302 and the positioning shaft 303 to move. When the positioning shaft 303 is separated from the circular hole on the circular plate 603, the limiting effect on the circular plate 603 is released. When the movable plate 302 moves, the cross bar 304, the mounting plate 306, the laser cutting head 307 and the baffle 308 are synchronously driven to move, so that the laser cutting head 307 moves out of the cutting host 2 for cutting operation until the movable plate 302 contacts the partition plate 305. At this time, the removal operation of the laser cutting head 307 is completed. After the laser cutting head 307 is removed, it moves by pulling the pull rod 601. At this time, the second spring 604 is stressed and contracts. When the pressure rod 602 presses the control switch 202, the control switch 202 controls the laser cutting head 307 to start, so as to realize the cutting and processing function of the workpiece. After cutting is completed, the pull rod 601 is released. At this time, under the action of the second spring 604, the pull rod 601 and the pressure rod 602 are automatically reset. According to the above principle, after the laser cutting head 307 finishes cutting, by controlling the electric telescopic rod 301 to contract, the laser cutting head 307 can be stored. With the shielding and protection function of the baffle 308, it can not only prevent the laser cutting head 307 from being damaged due to collision, but also avoid the problem that workers are scalded by accidentally touching the laser cutting head 307. And when the laser cutting head 307 is reset, at this time, the positioning shaft 303 just engages with the circular hole on the circular plate 603, so as to realize the locking of the pull rod 601 and avoid the device from being started by workers accidentally touching it. And when the pressure rod 602 is reset, since the distance between the pressure rod 602 and the control switch 202 is 1 cm - 2 cm and the distance is small, it is difficult for the worker's finger to reach between the pressure rod 602 and the control switch 202 to press the control switch 202, so as to further realize the anti-misoperation function;

[0034] The limiting mechanism 5 includes a connecting frame 501. One end of the connecting frame 501 is fixedly connected with the circular plate 603, and the connecting frame 501 is slidably connected with the cutting host 2. And the other end of the connecting frame 501 is fixedly connected with the movable ring 502. At the same time, a ball shaft 503 is nested and slidably connected on the movable ring 502. The ball shaft 503 is slidably connected with the scale rod 402, and the ball shaft 503 is fixed on the limiting rack 504. And the limiting rack 504 is slidably connected with the scale rod 402. At the same time, the limiting rack 504 is engaged with the limiting tooth block 408 to realize the positioning function; A fixed frame 505 is also fixed on the movable ring 502, and a clamping block 506 is fixed on the fixed frame 505. And the clamping block 506 is nested with the lower opening of the rotating shaft 401 to realize the positioning;

[0035] When pulling the pull rod 601 to start the device for cutting, as Figures 1-7As shown, the pull rod 601 moves upward, synchronously driving the circular plate 603 to move, thereby driving the connecting frame 501, the movable ring 502, the ball shaft 503 and the limit rack 504 to move upward. When the pressure rod 602 contacts the control switch 202 for pressing, at this time, the limit rack 504 just engages with the limit tooth block 408 to achieve positioning, thereby realizing the locking function of the movable frame 407 and the limit frame 409, avoiding the deviation of the limit frame 409 during the cutting process and affecting the cutting accuracy. And when the movable ring 502 moves upward, it synchronously drives the fixed frame 505 and the clamping block 506 to move upward. When the pressure rod 602 contacts the control switch 202 for pressing, at this time, the clamping block 506 just nests with the lower opening of the rotating shaft 401 to achieve positioning, thereby realizing the angle locking of the scale rod 402, avoiding the rotation of the scale rod 402 during cutting, and further ensuring the cutting and processing accuracy of the workpiece. And when the cutting is completed, when the pull rod 601 is released, the locking of the scale rod 402 and the movable frame 407 can be synchronously released, facilitating the subsequent adjustment. This is the working principle of the portable laser cutting device.
