Description
Technical Field

[0002] A laser engraving machine is a device that uses a laser beam to engrave patterns, text or designs on the surface of various materials. It uses the high energy density of the laser beam to achieve the engraving effect by accurately etching or ablating the surface of the material. The laser head is a key component in the laser equipment that is responsible for focusing the laser beam and achieving specific functions.
[0003] The common way to fix the laser head is to insert the laser head into the mounting seat and then tighten the positioning bolts. The positioning bolts will hold the laser head tight to ensure its stability. However, the laser engraving machine will drive the laser head and the mounting seat to move during operation, which will cause jitter during the movement. When used for a long time, the jitter can easily cause the positioning bolts to reverse and loosen, which can easily cause the laser head to loosen. At the same time, in order to ensure the cooling of the workpiece and the laser head during processing, a common laser head generally has a cooling pipe installed on the side, and in order to facilitate the connection of the cooling pipe and the cooling pipe on the machine, a plug-in fixation method is generally adopted.

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0032] Reference Figure 1 , Figure 3 , Figure 4The utility model provides an embodiment: a laser head stabilizing structure for a laser engraving machine, including a machine table 1, which is the main body of the laser engraving machine. It is a prior art and can be implemented by technicians in this field. Since it is a prior art, it will not be described in detail in this case. A positioning block 2 is arranged on the upper surface of the machine table 1. Starting the machine table 1 can drive the positioning block 2 to move along the Y-axis and the X-axis. A mounting plate 3 is installed on the front surface of the positioning block 2. The mounting plate 3 is installed on the front surface of the positioning block 2 with bolts. A mounting seat 4 is fixedly connected to the front surface of the mounting plate 3. The mounting seat 4 is used to install a laser head body 5. The laser head body 5 is installed on the lower surface of the mounting seat 4. A clamping component is arranged on the left surface of the laser head body 5. The clamping assembly can connect the air blowing pipe 71 on the positioning block 2 and the fixing pipe 73 on the laser head body 5. An anti-loosening assembly is arranged inside the mounting seat 4. The anti-loosening assembly can prevent the positioning bolt 61 from reversing and loosening, and can ensure the stability of the laser head body 5. The common laser head body 5 is generally installed on the mounting seat 4 by tightening with the positioning bolt 61. However, after long-term use, the positioning bolt 61 is prone to reverse loosening due to the operation of the machine 1, affecting the stability of the laser head body 5. The anti-loosening assembly includes the positioning bolt 61, and the inner wall of the mounting seat 4 is elastically connected with a ring 65 through a limit spring 64. The left surface of the ring 65 is fixedly connected with a block 66, and the ring 65 and the block 66 will move synchronously.
[0033] Reference Figure 2 , Figure 4 , Figure 5 The anti-loosening component also includes a slot 601, the shape and size of which match the block 66, and the inner wall of the mounting seat 4 is elastically connected to the block 62 through a positioning spring 63.
[0034] Reference Figure 2 , Figure 6 The clamping assembly includes an air blowing pipe 71. The air blowing pipe 71 is a prior art and can be implemented by technicians in this field. Since it is a prior art, it will not be described in detail in this case. The lower surface of the laser head body 5 is penetrated and fixedly connected with an air outlet pipe 72. The air blowing pipe 71 can transport gas, and the gas will eventually be discharged from the air outlet pipe 72 to cool the workpiece and the laser head body 5. The upper surface of the laser head body 5 is penetrated and fixedly connected with a fixed pipe 73. The upper part of the outer wall of the fixed pipe 73 is provided with The thread has a lead angle of less than five degrees and has a self-locking function. A clamp block 74 is slidably connected to the upper surface of the fixed tube 73. There are multiple groups of clamp blocks 74, which are arranged in a circular array with the center of the fixed tube 73 as the origin. The multiple groups of clamp blocks 74 can synchronously shrink toward the center of the fixed tube 73 or synchronously open toward the edge of the fixed tube 73. An arc block 75 is fixedly connected to the right surface of the clamp block 74. A threaded ring 76 is threadedly connected to the outer wall of the fixed tube 73. When the threaded ring 76 is rotated, the threaded ring 76 will rise or fall.
[0035] Reference Figure 2 , Figure 6 One end of the air blowing pipe 71 is arranged on the left surface of the positioning block 2, and the other end of the air blowing pipe 71 is inserted into the inner wall of the fixed pipe 73. The air outlet pipe 72 is connected to the fixed pipe 73. The lower surface of the arc block 75 is set as an arc surface. By squeezing the arc surface of the arc block 75, the arc block 75 will drive the clamping block 74 to move toward the center of the fixed pipe 73 to clamp the air blowing pipe 71, thereby fixing the air blowing pipe 71.
[0036] Reference Figure 1 , Figure 3 , Figure 4 The positioning bolt 61 passes through and is threadedly connected to the left surface of the mounting seat 4 , one end of the limit spring 64 is fixedly connected to the right surface of the ring 65 , and the other end of the limit spring 64 is fixedly connected to the inner wall of the right side of the mounting seat 4 .
[0037] Reference Figure 4 - Figure 5 The circular ring 65 is slidably connected to the inner wall of the mounting seat 4. When the circular ring 65 moves to the right, it will squeeze the limit spring 64 to generate a reaction force. There are multiple groups of blocks 66, and there are multiple groups of slots 601. The multiple groups of blocks 66 and slots 601 are arranged in a circular array with the center of the circular ring 65 as the origin.
[0038] Reference Figure 4 - Figure 5 The slot 601 is provided on the right surface of the positioning bolt 61, and the slot 601 is provided in an arc shape. The left surface of the block 66 is set as an arc surface, and the block 66 is inserted into the inner wall of the slot 601. The positioning bolt 61 will drive the slot 601 to move when it shakes and reverses. When the slot 601 moves, it will squeeze the arc surface of the block 66. When the block 66 is squeezed, it will drive the ring 65 to move to the right to squeeze the limit spring 64 to generate a reaction force. Then, under the push of the reaction force of the limit spring 64, the ring 65 and the block 66 will move to the left, and the block 66 will squeeze the slot 601 to make the positioning bolt 61 rotate forward and be tightened to prevent loosening, and ensure that the positioning bolt 61 can tightly hold the laser head body 5 to ensure stability.
[0039] Reference Figure 4 - Figure 5 One end of the positioning spring 63 is fixedly connected to the upper surface of the stopper 62, and the other end of the positioning spring 63 is fixedly connected to the inner wall at the top of the mounting seat 4. When the stopper 62 moves upward, it will squeeze the positioning spring 63 to generate a reaction force. The stopper 62 is slidably connected to the inner wall of the mounting seat 4. The left surface of the stopper 62 is set as an inclined surface, and the right surface of the stopper 62 is set as an inclined surface. When the inclined surface of the stopper 62 is squeezed, the stopper 62 will move upward.
[0040] Working principle: When the device is used, if the laser head body 5 needs to be replaced, the threaded ring 76 can be rotated in the opposite direction to move the threaded ring 76 downward to release the squeezing of the arc surface of the arc block 75. The arc block 75 and the clamping block 74 will be in a loose state, and then the air pipe 71 can be pulled out of the fixed pipe 73.
[0041] Then unscrew the positioning bolt 61. When the positioning bolt 61 is unscrewed, the inclined surface of the stopper 62 will be squeezed to make the stopper 62 move upward and retract into the interior of the mounting seat 4 to release the obstruction to the positioning bolt 61. After the positioning bolt 61 is unscrewed, it will be separated from the laser head body 5 to release the limit on the laser head body 5. Then remove the laser head body 5 from the mounting seat 4, take out the new laser head body 5, align it with the lower surface of the mounting seat 4 and install it. After the installation is completed, tighten the positioning bolt 61. During the tightening process of the positioning bolt 61, the inclined surface on the other side of the stopper 62 will be squeezed to make the stopper 62 move upward and retract into the interior of the mounting seat 4 to release the obstruction to the positioning bolt 61. After the positioning bolt 61 is tightened The squeezing of the block 62 will be released, and the block 62 will move downward again under the push of the positioning spring 63 to block the positioning bolt 61, and when the positioning bolt 61 is tightened, the laser head body 5 will be pressed tightly to prevent the laser head body 5 from loosening. At the same time, the slot 601 will be aligned with the block 66, and the block 66 will be plugged into the slot 601. At this time, the installation of the laser head body 5 is completed, and then the air blow pipe 71 is inserted into the fixed tube 73 and the threaded ring 76 is rotated to make the threaded ring 76 move upward to squeeze the arc surface of the arc block 75. When the arc block 75 is squeezed, it will drive the clamping block 74 to move toward the center of the fixed tube 73 to clamp the air blow pipe 71 to ensure the stability of the installation of the air blow pipe 71.
[0042] When the machine 1 is running, the positioning bolt 61 will drive the slot 601 to move due to the shaking and reversing. When the slot 601 moves, it will squeeze the arc surface of the block 66. The squeezed block 66 will drive the ring 65 to move to the right to squeeze the limit spring 64 to generate a reaction force. Since the reversal angle of the positioning bolt 61 caused by a single shaking is limited, when the device stops shaking, the reaction force of the limit spring 64 will push the ring 65 and the block 66 to move to the left. The block 66 moving to the left will squeeze the slot 601 to make the positioning bolt 61 rotate forward and tighten, which can tightly hold the laser head body 5 to ensure stability.
[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
