Description

Technical Field

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

[0002] Laser cutting machines focus the laser light emitted from a laser generator into a high-power density laser beam through an optical system. The laser beam irradiates the surface of the workpiece, causing it to reach its melting or boiling point. Simultaneously, high-pressure gas coaxial with the beam blows away the molten or vaporized metal.

[0003] However, in actual applications, when most existing laser cutting devices are used to cut standard plate-shaped metal parts, a large amount of sparks and slag will be generated on the cutting surface of the metal parts, which will fly around irregularly. Since workers need to keep an eye on the cutting status, the flying sparks and slag can easily cause burns to the workers' skin, leading to danger. Although workers usually wear protective clothing to wrap themselves up, the hot summer is not conducive to this. Protective clothing can easily cause workers to suffer from heatstroke, which is not conducive to its promotion and use.

[0004] Therefore, those skilled in the art provide a laser cutting device for metal parts to solve the problems raised in the above background technology. Utility Model Content

[0005] In order to solve the problem proposed in the above background technology that the cutting surface of the metal parts will generate a large amount of spark slag and fly around irregularly, since the workers need to keep paying attention to the cutting status, the flying spark slag can easily cause burns to the workers' skin, leading to danger. Although workers usually wear protective clothing to wrap themselves, the hot summer is not good, and the protective clothing can easily cause heatstroke in the workers, which is not conducive to promotion and use. The present application provides a laser cutting device for metal parts.

[0006] The present application provides a laser cutting device for metal parts, which adopts the following technical solution: it includes a placing table, the front and rear sides of the placing table are slidably connected to the same U-shaped frame, the top side of the U-shaped frame is provided with a rectangular hole, the top side of the U-shaped frame is fixedly connected to a motor, the output shaft of the motor is fixedly connected to a screw rod, the outer spiral transmission sleeve of the screw rod is connected to a transmission block, the transmission block is slidably connected to the inner wall of the rectangular hole, the bottom side of the transmission block is fixedly connected to an electric telescopic rod, the output shaft of the electric telescopic rod is fixedly connected to a mounting plate, the bottom side of the mounting plate is fixedly installed with a laser cutting head body, and the outer side of the output shaft of the electric telescopic rod is slidably connected to a shield.

[0007] Preferably, two T-shaped rods are fixedly connected to the top side of the mounting plate, the shield is slidably sleeved on the outer sides of the two T-shaped rods, the top inner walls of the two T-shaped rods are fixedly connected to springs, and the two springs are fixedly connected to the top side of the shield.

[0008] Preferably, a connecting thread is provided on the outer side of the baffle, and a cover is connected to the outer side of the baffle via the thread.

[0009] Preferably, the bottom side of the shield is designed to be semicircular.

[0010] Preferably, the front and rear inner walls of the rectangular hole are fixedly connected to a same guide rod, and the transmission block is slidably sleeved on the guide rod.

[0011] In summary, this application has the following beneficial technical effects:

[0012] 1. By setting up a shield, the plate-shaped metal parts are placed on the placement table, and the left and right mobility of the U-shaped frame is utilized. In cooperation, the output shaft of the motor drives the screw rod to rotate, and the screw rod drives the transmission block to move. The transmission block cooperates with the electric telescopic rod to drive the mounting plate to move, and the mounting plate drives the laser cutting head body to move longitudinally, so that cutting operations can be performed on different positions of the placed metal parts. When the electric telescopic rod adjusts the distance between the laser cutting head body and the metal part, the shield will contact the surface of the placed metal part in advance. As the laser cutting head body continues to move, a sliding will be formed between the shield and the output shaft of the electric telescopic rod, and it can move synchronously with the movement of the laser cutting head body. At this time, the shield can be used to seal the cutting environment during the cutting operation, thereby effectively avoiding the situation where sparks and slag are splashed everywhere, so that workers can still be effectively protected without wearing protective clothing, avoiding the occurrence of danger, which is conducive to promotion and use.

[0013] 2. By setting the spring, the two springs cooperate with each other. When the springs are squeezed and contracted, the rebound force generated will act on the shield, so that the shield can always be in a downward pressing state during the cutting process, ensuring that the shield is always in contact with the surface of the metal part during the cutting process, thereby improving safety and avoiding the occurrence of sparks and slag splashing.

Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0019] The present application discloses a laser cutting device for metal parts, referring to Figure 1-3 , including a placing table 1, the front and rear sides of the placing table 1 are slidably connected with the same U-shaped frame 2, the top side of the U-shaped frame 2 is provided with a rectangular hole, the top side of the U-shaped frame 2 is fixedly connected with a motor 3, the output shaft of the motor 3 is fixedly connected with a screw rod 4, the outer spiral transmission sleeve of the screw rod 4 is connected with a transmission block 5, the transmission block 5 is slidably connected to the inner wall of the rectangular hole, the bottom side of the transmission block 5 is fixedly connected with an electric telescopic rod 6, the output shaft of the electric telescopic rod 6 is fixedly connected with a mounting plate 7, the bottom side of the mounting plate 7 is fixedly installed with a laser cutting head body 8, and the outer side of the output shaft of the electric telescopic rod 6 is slidably connected with a blocking cover 9; by setting the blocking cover 9, the plate-like metal parts are placed on the placing table 1, and the left and right mobility of the U-shaped frame 2 is utilized, and the output shaft of the motor 3 drives the screw rod 4 to rotate, and the screw rod 4 drives the transmission block 5 to move, The transmission block 5 cooperates with the electric telescopic rod 6 to drive the mounting plate 7 to move, and the mounting plate 7 drives the laser cutting head body 8 to move longitudinally, so that cutting operations can be performed on different positions of the placed metal parts. When the electric telescopic rod 6 adjusts the distance between the laser cutting head body 8 and the metal part, the shield 9 will contact the surface of the placed metal part in advance. As the laser cutting head body 8 continues to move, a sliding will be formed between the shield 9 and the output shaft of the electric telescopic rod 6, and it can move synchronously with the movement of the laser cutting head body 8. At this time, the shield 9 can be used to seal the cutting environment during the cutting operation, thereby effectively avoiding sparks and slag flying everywhere, so that workers can still be effectively protected without wearing protective clothing, avoiding the occurrence of danger, which is conducive to promotion and use.

[0020] In the present application, two T-shaped rods 10 are fixedly connected to the top side of the mounting plate 7, and the shield 9 is slidably sleeved on the outer sides of the two T-shaped rods 10. The inner walls of the top sides of the two T-shaped rods 10 are fixedly connected with springs 11, and the two springs 11 are fixedly connected to the top side of the shield 9; by setting the springs 11, the two springs 11 cooperate with each other, and the rebound force generated when the springs 11 are squeezed and contracted will act on the shield 9, so that the shield 9 can always be in a downward pressing state during the cutting process, ensuring that the shield 9 is always in contact with the surface of the metal part during the cutting process, thereby improving safety and avoiding the occurrence of sparks and slag splashing.

[0021] In the present application, a connecting thread is provided on the outer side of the shield 9, and a cover 12 is connected to the outer side of the shield 9 through the thread; by setting the cover 12, when the cutting operation is completed, the cover 12 is screwed to the shield 9, and the interior of the shield 9 is in a sealed state, thereby preventing dust in the air from adhering to the laser cutting head body 8 and affecting the subsequent cutting operation, thereby protecting the laser cutting head body 8 when not in use.

[0022] In the present application, the bottom side of the shield 9 is designed to be semicircular; by setting the bottom side of the shield 9 to be semicircular, the friction between the shield 9 and the surface of the placed plate-shaped metal part can be reduced to a minimum, thereby improving the smoothness of movement.

[0023] In the present application, the front and rear inner walls of the rectangular hole are fixedly connected with the same guide rod 13, and the transmission block 5 is slidably connected to the guide rod 13; by setting the guide rod 13, when the transmission block 5 moves, the guide rod 13 limits the transmission block 5, so that the transmission block 5 can maintain a straight line direction of movement to avoid deviation, thereby improving the accuracy of the cutting operation.

[0024] The standard parts used in this utility model can all be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here.

[0025] The implementation principle of a laser cutting device for metal parts in the embodiment of the present application is as follows: when in use, a plate-shaped metal part is placed on a placing table 1, and the left and right mobility of the U-shaped frame 2 is utilized. In cooperation, the output shaft of the motor 3 drives the screw rod 4 to rotate, and the screw rod 4 drives the transmission block 5 to move. The transmission block 5 cooperates with the electric telescopic rod 6 to drive the mounting plate 7 to move, and the mounting plate 7 drives the laser cutting head body 8 to move longitudinally, so that cutting operations can be performed on different positions of the placed metal parts. When the electric telescopic rod 6 adjusts the distance between the laser cutting head body 8 and the metal part, the shield 9 will contact the surface of the placed metal part in advance. As the laser cutting head body 8 continues to move, a sliding will be formed between the shield 9 and the output shaft of the electric telescopic rod 6, and it can move synchronously with the movement of the laser cutting head body 8. At this time, the shield 9 can be used to form a sealed cutting environment during the cutting operation, thereby effectively preventing sparks and slag from flying everywhere, so that workers can still be effectively protected without wearing protective clothing, avoiding dangerous situations. The laser cutting head body 8 is convenient to use and can be widely used. The two springs 11 cooperate with each other. When the springs 11 are squeezed and contracted, the rebound force generated will act on the shield 9, so that the shield 9 is always in a downward pressing state during the cutting process, ensuring that the shield 9 is always in contact with the surface of the metal part during the cutting process, thereby improving safety and avoiding the occurrence of sparks and slag splashing. When the cutting operation is completed, the cover 12 is screwed to the shield 9. At this time, the interior of the shield 9 is in a sealed state, thereby preventing dust in the air from adhering to the laser cutting head body 8 and affecting the subsequent cutting operation, so that the laser cutting head body 8 can be protected when not in use. The bottom side of the shield 9 is semicircular, so that when the shield 9 contacts the surface of the placed plate-like metal part, the friction between the two is reduced to a minimum, thereby improving the smoothness of movement. When the transmission block 5 moves, the guide rod 13 limits the transmission block 5, so that the transmission block 5 can keep moving in a straight line to avoid deviation, thereby improving the accuracy of the cutting operation.
