Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting machines, in particular to a laser cutting machine with a protective structure. Background Art

[0002] A laser cutting machine focuses the laser light emitted from a laser generator into a high-power, high-density laser beam through an optical system. The laser beam strikes the workpiece surface, causing it to reach its melting or boiling point. Simultaneously, high-pressure gas coaxial with the beam blows away the molten or vaporized metal, achieving the desired cutting effect.

[0003] In the existing laser cutting machine, in order to prevent the laser from damaging the laser cutting machine itself after penetrating the workpiece to be cut, a conical support member is generally used to support the workpiece to be cut. However, the surface of such a conical support member is still prone to the accumulation of molten material generated during laser cutting, and the laser after penetrating the workpiece will also damage these support members. Therefore, to address this problem, a laser cutting machine with a protective structure is needed to be improved. Utility Model Content

[0004] The purpose of the present invention is to provide a laser cutting machine with a protective structure to solve the problems raised in the above background technology.

[0006] Preferably, the transmission mechanism includes a screw, a sliding rod, and a support plate. A screw is movably provided on one side of the lower end of the cutting table through a bearing, and a sliding rod is fixedly provided on the side of the lower end of the cutting table away from the screw. A support plate is movably sleeved on the outer surface of the sliding rod, and the end of the support plate close to the screw is movably sleeved on the outer surface of the screw through a threaded sleeve. Through the transmission mechanism, a simple structure can be used in conjunction with the notches set at intervals to drive multiple different movable plates to move up and down respectively.

[0007] Preferably, an electric motor is fixedly provided on one side of the cutting table surface, and the output shaft end of the electric motor is connected to the screw through a coupling, so that the screw can be driven to rotate by the electric motor; thereby, the support plate can be driven to move along the sliding rod through the screw; when the support plate moves to a position aligned with the notch of the connecting plate; the connecting plate and the corresponding movable rod and movable plate will move downward.

[0008] Preferably, the notches on the surface of the connecting plate are arranged evenly in oblique lines; Figure 2 As shown, all the notches are evenly spaced in an oblique line in sequence; the purpose is that when the support plate moves to the notch position; the connecting plate, the movable rod and the corresponding movable plate and the conical support block can all move downward, so that the movable plate and the conical support block can be moved away from the cutting position, thereby protecting the function of the protective device itself; and the device is provided with multiple groups of movable plates and conical support blocks, even if one group of movable plates and conical support blocks moves downward and away, it will not affect the normal fixed support work of the device.

[0009] Preferably, the two sides of the notch surface are inclined, such as Figure 6 As shown, the surface of the notch is set to be inclined, so that when the support plate is stuck in the notch, the support plate can also move out of the notch; when the support plate moves to both sides; due to the inclination of the notch surface, the notch can be squeezed to make the connecting plate and the movable plate and movable rod move upward; thereby finally making the support plate detach from the notch.

[0010] Preferably, the movable plates and conical support blocks are provided in multiple groups and are evenly spaced and distributed at the upper end of the cutting table, and the plates to be cut are jointly supported by the multiple groups of movable plates and conical support blocks; in this way, when a group of movable plates and conical support blocks moves downward, the normal support work of the entire device will not be affected.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. When cutting, the present invention lowers the movable plate and the conical support block closest to the laser cutting head wherever the laser cutting head is located, so that the movable plate and the conical support block near the laser cutting area can be moved away from the cutting area, thereby protecting the protective device itself.

[0013] 2. When the utility model is used, the lifting and lowering of multiple sets of movable plates and conical support blocks are completed by using a screw to drive a support plate to move horizontally, and then cooperating with the notches set at the angles on both sides. There is no need to set a set of lifting structures for each movable plate and conical support block, which can greatly reduce the cost of the device and facilitate its popularization and use.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-7The utility model provides a technical solution: a laser cutting machine with a protective structure, comprising a cutting table 1, wherein the cutting table 1 is internally provided with a supporting mechanism for supporting the parts to be cut, wherein the supporting mechanism comprises a movable rod 2, a movable plate 3, a conical support block 4, a connecting plate 5, and a notch 6, and a plurality of movable rods 2 are evenly and movably interspersed inside the cutting table 1, a movable plate 3 is fixedly provided on the upper end of the movable rod 2, a conical support block 4 is fixedly provided on the upper end of the movable plate 3, a connecting plate 5 is fixedly provided on the lower end of the movable rod 2, a notch 6 is provided on the outer surface of the lower end of the connecting plate 5, and a transmission mechanism for controlling the lifting and lowering of the support plate 9 is provided at the lower end of the cutting table 1.

[0024] The transmission mechanism includes a screw 7, a slide rod 8, and a support plate 9. A screw 7 is movably provided on one side of the lower end of the cutting table 1 through a bearing. A slide rod 8 is fixedly provided on the side of the lower end of the cutting table 1 away from the screw 7. A support plate 9 is movably sleeved on the outer surface of the slide rod 8. The end of the support plate 9 close to the screw 7 is movably sleeved on the outer surface of the screw 7 through a thread. The transmission mechanism can use a simple structure to cooperate with the notches 6 set at intervals to drive multiple different movable plates 3 to move up and down respectively;

[0025] A motor 10 is fixedly provided on one side of the surface of the cutting table 1. The output shaft end of the motor 10 is connected to the screw 7 through a coupling. The motor 10 can drive the screw 7 to rotate; thereby, the screw 7 can drive the support plate 9 to move along the slide rod 8; when the support plate 9 moves to a position aligned with the notch 6 of the connecting plate 5, the connecting plate 5 and the corresponding movable rod 2 and movable plate 3 will move downward;

[0026] The notches 6 on the surface of the connecting plate 5 are arranged evenly in a diagonal pattern; Figure 2 As shown, all the notches 6 are evenly spaced in an oblique line in sequence; the purpose is that when the support plate 9 moves to the position of the notch 6; the connecting plate 5, the movable rod 2 and the corresponding movable plate 3 and the conical support block 4 can all move downward, so that the movable plate 3 and the conical support block 4 can be moved away from the cutting position, thereby protecting the function of the protective device itself; and the device is provided with multiple groups of movable plates 3 and conical support blocks 4, even if one group of movable plates 3 and conical support blocks 4 moves downward and away, it will not affect the normal fixed support work of the device;

[0027] The two sides of the notch 6 are inclined, as shown in FIG. Figure 6 As shown, the surface of the notch 6 is inclined, so that when the support plate 9 is inserted into the notch 6, the support plate 9 can also be moved out of the notch 6; when the support plate 9 moves to both sides; due to the inclination of the notch 6 surface, the notch 6 can be squeezed to move the connecting plate 5 and the movable plate 3 and the movable rod 2 upward; thereby finally causing the support plate 9 to detach from the notch 6;

[0028] The movable plates 3 and the conical support blocks 4 are provided in multiple groups and are evenly spaced and distributed on the upper end of the cutting table 1. The plates to be cut are supported by the multiple groups of movable plates 3 and conical support blocks 4. In this way, when a group of movable plates 3 and conical support blocks 4 moves downward, the normal support work of the entire device will not be affected.

[0029] Working principle: When using this device, all movable plates 3 and conical support blocks 4 are initially kept at the same horizontal line. The conical support blocks 4 can then be used to support the plate to be cut. The plate can then be cut using the laser cutting device in the prior art. During cutting, the movable plate 3 and conical support blocks 4 closest to the laser cutting head are lowered to the laser cutting head, so that the movable plate 3 and conical support blocks 4 near the laser cutting position can be moved away from the cutting position, thereby protecting the protective device itself.

[0030] When the conical support block 4 is controlled to descend, the screw rod 7 is driven to rotate by the motor 10, so that the support plate 9 can be driven to slide along the slide rod 8 by the screw rod 7. When the support plate 9 moves to the position of the notch 6, the connecting plate 5, the movable rod 2 and the corresponding movable plate 3 and the conical support block 4 can all move downward, so that the movable plate 3 and the conical support block 4 can be kept away from the cutting position, thereby protecting the function of the protective device itself. In addition, the device is provided with multiple groups of movable plates 3 and conical support blocks 4. Even if one group of movable plates 3 and conical support blocks 4 moves downward and away, it will not affect the normal fixed support work of the device.

[0031] When the device is in use, the lifting and lowering of multiple sets of movable plates 3 and conical support blocks 4 are completed by using a screw 7 to drive a support plate 9 to move horizontally, and then cooperating with the notches 6 set obliquely on both sides. There is no need to set a lifting structure for each movable plate 3 and conical support block 4, which can greatly reduce the cost of the device and facilitate its popularization and use.

[0032] When this device is in use, it only protects the material support part of the laser cutting machine, and the laser cutting part is a mature technology in the existing technology. Generally, a laser cutting head is installed through a three-axis translation structure, and the laser cutting head is used to move to perform cutting work; and the material support part of this device does not conflict with the traditional laser cutting part, so there is no need to modify the laser cutting part; therefore, this application document does not introduce the laser cutting part in detail.

[0033] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.
