Description

Technical Field

[0001] This utility model relates to the field of laser cutting machines, and in particular to a laser cutting machine with safety protection functions. Background Technology

[0002] Chinese Patent CN219379422U discloses a safety protection structure for a laser cutting machine, including a base, support columns on the left and right sides of the top of the base, a cutting seat between the two support columns on the top of the base, a connecting horizontal plate at the end of the two support columns away from the base, an electric push rod at the bottom of the connecting horizontal plate, and the laser cutting machine body at the output end of the electric push rod. Strip plates are located on the left and right sides of the cutting seat on the top of the base, between the two support columns. A protective frame is provided on the top of the base, and the cutting seat is located within the protective frame. Inside, the protective frame is located between two strip plates. A snap-fit ​​frame is provided on both the left and right sides of the protective frame. A snap-fit ​​assembly that is slidably connected to the top of the base is provided on the opposite sides of the two strip plates. The snap-fit ​​assembly includes two connecting springs respectively provided on the opposite sides of the two strip plates, and a rectangular plate with one end connected to the base at the end of the connecting springs away from the strip plates. A connecting shaft is provided on the opposite sides of the two rectangular plates, and a rack plate is provided on the opposite sides of the two connecting shafts. A servo motor is provided on the opposite sides of the two rectangular plates, and a gear that meshes with the rack plate is provided at the output end of the servo motor.

[0003] When the protective frame in the above structure is needed, a servo motor drives the gear to rotate, which in turn drives the rack plate that it is matched with to move. At this time, the protective frame will move upward with the rack plate, so that the cutting seat is covered in it, thereby playing a protective role. However, in the above structure, the protective frame needs to be completely covered outside the cutting seat, and the protective frame needs the cooperation of the servo motor, gear and rack plate to play a protective role when in use, which results in a high cost of using the protective frame. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies where the protective frame needs to be completely covered outside the cutting base, and the protective frame requires the cooperation of a servo motor, gears, and rack plates to achieve its protective function, resulting in high operating costs. It provides a laser cutting machine with safety protection functions that can reduce operating costs.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A laser cutting machine with safety protection function includes a laser cutting machine body, a cutting head disposed on the laser cutting machine body, and a protective mechanism disposed on the outer wall of the cutting head to protect workers in the vicinity when the cutting head is in operation. The protective mechanism includes a protective cover fitted on the outer wall of the cutting head, and a detachable component disposed between the protective cover and the cutting head for assembling and disassembling the two. The detachable component includes an insert block disposed on the outer wall of the cutting head, a slot disposed on the protective cover for vertical insertion of the insert block when the protective cover is covering the outer wall of the cutting head, and an anti-dislodgement component for preventing the insert block from dislodging from the slot after it is inserted into the slot.

[0007] With the above solution, the insert block set on the outer wall of the cutting head can be inserted into the slot inside the protective sleeve when the protective sleeve is installed on the outer wall of the cutting head. After the insert block is inserted into the slot, it can be fixed in the slot by the anti-detachment component, thereby reducing the probability of the protective sleeve falling off the cutting head. This allows the protective sleeve to protect the cutting head during use, reducing the probability of workers around the laser cutting machine being injured by sparks generated by the cutting head. At the same time, the installation and removal of the protective sleeve and the cutting head are convenient and the cost of use is low.

[0008] Preferably, the anti-detachment component includes an arc-shaped groove inside the protective cover, one end of which is connected to the slot. After the insert is inserted into the slot, it can move horizontally inside the arc-shaped groove. A limiting component is provided at the end of the arc-shaped groove away from the slot to restrict the movement of the insert in the arc-shaped groove.

[0009] Using the above method, when the insert is inserted into the slot, the protective cover can be rotated to allow the insert to move horizontally away from the slot within the arc groove. After the insert has moved within the arc groove, the position of the insert can be limited by the limiting component, preventing the insert from moving further within the arc groove. At this point, the installation between the protective cover and the cutting head can be completed.

[0010] Preferably, the limiting component includes a mounting hole that is vertically arranged at the end of the arc groove away from the slot and communicates with the arc groove. A limiting shaft is provided in the mounting hole, with one end passing through the mounting hole and inserted into the arc groove. The insert block is provided with a limiting insertion hole that allows the limiting shaft to be inserted into the limiting shaft when the insert block moves to the limiting shaft and limits the movement of the insert block.

[0011] Using the above solution, one end of the limiting shaft set in the mounting hole can be inserted into the arc-shaped groove. When the insert block moves, when the limiting hole on it is aligned with the limiting shaft, it is inserted into the limiting hole on the insert block, thereby limiting the position of the insert block in the arc-shaped groove and preventing the insert block from coming out of the arc-shaped groove. This realizes the installation between the protective cover and the cutting head, thereby reducing the cost of using the protective cover.

[0012] Preferably, a guide component is provided on the limiting shaft to automatically raise and lower the limiting shaft when the insert block moves to the limiting shaft, so as to avoid subsequent movement of the insert block.

[0013] Preferably, the guide component includes a guide slope provided on the insertion end of the limiting shaft, the guide slope being oriented toward the slot and increasing in inclination from the direction near the insertion end of the limiting shaft to the direction away from the insertion end of the limiting shaft.

[0014] Using the above scheme, the guide slope set on the limiting shaft can squeeze the guide slope when the insert block moves to abut against its surface, thereby driving the limiting shaft to partially retract into the mounting hole. At this time, the insert block can continue to move away from the slot in the arc groove. When the insert block moves to the point where the limiting insertion hole on it is directly opposite the limiting shaft, the limiting shaft will fall and insert into the limiting insertion hole, thereby limiting the movement of the insertion hole and preventing it from coming out of the arc groove, thus realizing the installation between the protective cover and the cutting head.

[0015] Preferably, a blocking component is provided on the limiting shaft near the insertion end to prevent the limiting shaft from coming out of the mounting hole.

[0016] Preferably, the blocking component includes a blocking ring protruding on the outer wall of the limiting shaft near the insertion end, a relief hole provided on the protective cover to avoid the movement of the blocking ring, and an elastic component provided between the bottom of the relief hole and the blocking ring to drive the limiting shaft to be partially inserted into the arc-shaped groove under normal conditions.

[0017] Using the above scheme, the blocking ring set on the outer wall of the limiting shaft can prevent the limiting shaft from coming out of the mounting hole. The elastic component set between the blocking ring and the clearance hole can drive the limiting shaft to be partially inserted into the arc groove under normal conditions. At the same time, after the limiting shaft retracts, it can drive the limiting shaft to move into the arc groove for reset.

[0018] Preferably, the elastic component includes a spring disposed between the blocking ring and the bottom of the clearance hole, with both ends of the spring abutting against each other, and the spring being sleeved on the outer wall of the limiting shaft.

[0019] Using the above scheme, the spring set between the blocking ring and the clearance hole can drive the limiting shaft to be partially inserted into the arc groove, while the spring sleeved outside the limiting shaft can prevent the spring from shifting between the blocking ring and the clearance hole.

[0020] Preferably, a heat-absorbing component is provided on the inner wall of the protective cover to absorb the heat generated when the cutting head is in use.

[0021] Preferably, the heat-absorbing component includes a plurality of heat-absorbing sheets evenly embedded in the inner wall of the protective cover, and a heat dissipation groove is provided on the outer wall of the protective cover opposite to the heat-absorbing sheets to facilitate heat dissipation of the heat-absorbing sheets.

[0022] Using the above solution, the heat-absorbing fins set on the inner wall of the protective cover can absorb the heat generated by the cutting head, thereby reducing the temperature of the cutting head during use and increasing the service life of the cutting head. Meanwhile, the heat dissipation grooves set on the protective cover can facilitate the heat dissipation of the heat-absorbing fins themselves, thereby improving the heat dissipation performance of the heat-absorbing fins.

[0023] This utility model, by adopting the above technical solution, has significant technical effects: the insert block set on the outer wall of the cutting head can be inserted into the slot inside the protective sleeve when the protective sleeve is installed on the outer wall of the cutting head. After the insert block is inserted into the slot, it can be fixed in the slot by the anti-detachment component, thereby reducing the probability of the protective sleeve falling off the cutting head. This allows the protective sleeve to protect the cutting head during use, reducing the probability of workers around the laser cutting machine being injured by sparks generated by the cutting head. At the same time, the installation and removal of the protective sleeve and the cutting head are convenient and the cost of use is low. Attached Figure Description

The detachable component includes an insert 5 mounted on the outer wall of the cutting head 2, a slot 4 mounted on the protective cover 3 for vertical insertion of the insert 5 when the protective cover 3 is mounted on the outer wall of the cutting head 2, and an anti-detachment component to prevent the insert 5 from being dislodged from the slot 4 after it is inserted into the slot 4. In this embodiment, two inserts 5 are provided and symmetrically arranged on the outer wall of the cutting head 2. The number of anti-detachment components and slots 4 corresponds one-to-one with the number of inserts 5.

[0037] refer to Figures 3-6 , Figures 8-9 The anti-detachment component includes an arc-shaped groove 6 located inside the protective cover 3, one end of which communicates with the slot 4. After the insert 5 is inserted into the slot 4, it can move horizontally inside the arc-shaped groove 6. A limiting component is provided at the end of the arc-shaped groove 6 away from the slot 4 to restrict the movement of the insert 5 in the arc-shaped groove 6. The limiting component includes a mounting hole 7 vertically located at the end of the arc-shaped groove 6 away from the slot 4 and communicating with the arc-shaped groove 6. A limiting shaft 8 is provided inside the mounting hole 7, one end of which passes through the mounting hole 7 and is inserted into the arc-shaped groove 6 (in this embodiment, the end of the limiting shaft 8 away from the arc-shaped groove 6 extends outwards). (Outside the mounting hole 7), the insert 5 is provided with a limiting insertion hole 9, which allows the limiting shaft 8 to be inserted into the insert 5 when the insert 5 moves to the limiting shaft 8 and limits the movement of the insert 5. The limiting shaft 8 is provided with a guide component that drives the limiting shaft 8 to automatically rise and fall when the insert 5 moves to the limiting shaft 8 to avoid the subsequent movement of the insert 5. The guide component includes a guide inclined surface 10 provided on the insertion end of the limiting shaft 8. The guide inclined surface 10 faces the slot 4 and is inclined from the direction close to the insertion end of the limiting shaft 8 to the direction away from the insertion end of the limiting shaft 8.

[0038] refer to Figures 4-5 , Figure 9 A blocking component is provided on the limiting shaft 8 near the insertion end to prevent the limiting shaft 8 from coming out of the mounting hole 7. The blocking component includes a blocking ring 11 protruding on the outer wall of the limiting shaft 8 near the insertion end. A relief hole 12 is provided on the protective cover 3 to avoid the movement of the blocking ring 11. An elastic component is provided between the bottom of the relief hole 12 and the blocking ring 11 to drive the limiting shaft 8 to be partially inserted into the arc-shaped groove 6 under normal conditions. The elastic component includes a spring 13 provided between the blocking ring 11 and the bottom of the relief hole 12. The two ends of the spring 13 abut against each other, and the spring 13 is sleeved on the outer wall of the limiting shaft 8.

[0039] refer to Figure 7 The inner wall of the protective cover 3 is provided with a heat-absorbing component for absorbing the heat generated when the cutting head 2 is used. The heat-absorbing component includes a plurality of heat-absorbing sheets 14 evenly embedded in the inner wall of the protective cover 3. A heat dissipation groove 15 is provided on the outer wall of the protective cover 3 opposite to the heat-absorbing sheets 14 to facilitate heat dissipation of the heat-absorbing sheets 14. An observation window 16 is also provided on the outer wall of the protective cover 3 to facilitate workers to observe the status of the cutting head 2.

[0040] Specific disassembly and assembly process: When the protective cover 3 needs to be installed on the cutting head 2, firstly, the protective cover 3 is fitted onto the outer wall of the cutting head 2 from bottom to top. During the installation of the protective cover 3, the slot 4 inside the protective cover 3 can be aligned with the insert block 5 on the outer wall of the cutting head 2, so that the insert block 5 is inserted into the slot 4. When the insert block 5 is inserted into the slot 4, the protective cover 3 can be rotated to move the insert block 5 in the arc groove 6. When the insert block 5 abuts against the limiting shaft 8 in the arc groove 6, as the insert block 5 continues to move, the insert block 5 will be squeezed by the guide inclined surface 10 on the limiting shaft 8, thereby driving the limiting shaft 8 to move. The positioning shaft 8 retracts into the mounting hole 7, at which point the insert block 5 can continue to move in the arc groove 6. When the limiting insertion hole 9 on the insert block 5 is aligned with the limiting shaft 8, the limiting shaft 8 will be inserted into the limiting insertion hole 9 under the action of the spring 13, and the movement of the insert block 5 will be limited. At this time, the protective cover 3 can be installed on the cutting head 2. When the protective cover 3 needs to be removed, first, pull the limiting shaft 8 upward to disengage the limiting shaft 8 from the limiting insertion hole 9. At this time, the insert block 5 can move in the arc groove 6. When the insert block 5 moves to the slot 4, the protective cover 3 can be removed from the cutting head 2.
