Description

Technical Field

[0001] The utility model relates to the technical field of laser nozzles, and more specifically, it relates to a positioning device for laser nozzle processing. Background Art

[0002] The laser nozzle is an important component of a laser cutter, which is used to control the laser at the front end of the emitter. Due to its contact with the laser, the service life of the laser nozzle is short, and there is a large demand for its use.

[0003] When processing the laser nozzle, it is necessary to position and fix the workpiece to ensure stability during processing. Since the volume of the laser nozzle is small, ordinary fixing structures are too large to be used. Generally, special fixing equipment is used to clamp and position the workpiece, so as to process the workpiece. However, the fixing structure of the structure is too single and cannot be adjusted. When facing laser nozzles of different sizes, it is necessary to prepare fixing equipment with a variety of adapted structures, which is rather troublesome and consumes too many resources; moreover, when pressing the workpiece with a clamping fixing structure, in order to ensure stable fixing, the workpiece needs to be clamped. When a small workpiece is stressed, if the pressure is too large, it may be damaged, affecting the quality of the laser nozzle; in addition, relying solely on the clamping fixing method, the fixing cannot be guaranteed to be complete. During processing, if the workpiece receives an additional impact, it may deviate, affecting the processing quality. Summary of the Utility Model

Detailed implementation manners

[0027] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. The following will describe the present utility model in detail with reference to the drawings and in combination with the embodiments.

[0028] It should be pointed out that, unless otherwise specified, all the technical and scientific terms used in the present application have the same meanings as those commonly understood by those of ordinary skill in the technical field to which the present application belongs.

[0029] In the present utility model, unless otherwise stated, the orientations such as "upper, lower" are usually in the directions shown in the drawings, or in the vertical, perpendicular or gravitational directions; similarly, for the convenience of understanding and description, "left, right" are usually in the left and right shown in the drawings; "inside, outside" refer to the inside and outside relative to the contours of the respective components, but the above orientation terms do not limit the present utility model.

[0030] Please refer to Figures 1-5 , a laser nozzle processing positioning device, including a base 1, a support plate 2 is provided on the base 1, a support groove 3 is opened on the support plate 2, multiple groups of support plates 2 are provided, and the support plate 2 includes a first clamping plate 4 and a second clamping plate 5. The support groove 3 is arranged inside the first clamping plate 4 and the second clamping plate 5. The first clamping plate 4 is slidably matched with the base 1. A sliding block 6 is slidably connected inside the base 1. The first clamping plate 4 is connected to the sliding block 6. An adjusting screw rod 7 is provided on the base 1. The adjusting screw rod 7 is matched with the sliding block 6;

[0031] Sliding cavities 8 are opened at both ends of the base 1. A sliding strip 9 is arranged inside the sliding cavity 8. The second clamping plate 5 is matched with the sliding strip 9. A buffer spring 10 is arranged between the sliding strip 9 and the inner wall of the sliding cavity 8. A pressing block 11 is arranged at one end of the sliding cavity 8. A driving screw rod 12 is provided at the outer end of the base 1. The driving screw rod 12 is in threaded cooperation with the base 1 and is in rotational cooperation with the pressing block 11.

[0032] In this embodiment, the overall structure is supported by the base 1. The laser nozzle is placed in the support groove 3 and positioned and fixed by the support of the support plate 2, and then processing is carried out. When installing the laser nozzle, a certain gap is left between the first clamping plate 4 and the second clamping plate 5, which is larger than the width of the laser nozzle. Then the laser nozzle is placed between the support grooves 3 of the first clamping plate 4 and the second clamping plate 5, and the laser nozzle is supported by the support groove 3. Then the adjusting screw rod 7 is controlled. By rotating the adjusting screw rod 7, the adjusting screw rod 7 cooperates with the sliding block 6 to provide power for the movement of the sliding block 6, so that the sliding block 6 drives the first clamping plate 4 to move closer to the second clamping plate 5, and thus cooperates with the second clamping plate 5 to clamp the laser nozzle. By adjusting the distance gap between the first clamping plate 4 and the second clamping plate 5, the laser nozzle of different sizes can be adapted for positioning and fixing.

[0033] More specifically, when the first clamping plate 4 cooperates with the second clamping plate 5, the pressure of the movement of the first clamping plate 4 will be transmitted to the second clamping plate 5 through the laser nozzle. The second clamping plate 5 under pressure will drive the sliding bar 9 to move. The movement of the sliding bar 9 will be supported by the buffer spring 10. As the sliding bar 9 moves, the buffer spring 10 compresses, and the pressure on the sliding bar 9 becomes larger, so that the second clamping plate 5 cooperates with the first clamping plate 4 to clamp the laser nozzle, and the excessive pressure will be transmitted to the buffer spring 10 and absorbed by the buffer spring 10 to prevent the laser nozzle from being damaged by excessive pressure. When the buffer spring 10 shrinks to a certain extent, it can be determined that the laser nozzle is clamped and positioned. At this time, the driving screw rod 12 is controlled. By rotating the driving screw rod 12 and cooperating with the base 1, the driving screw rod 12 moves inward along the base 1, driving the pressing block 11 to move towards the sliding bar 9 and pressing the sliding bar 9 to fix the sliding bar 9, thereby ensuring the fixation of the second clamping plate 5.

[0034] Please refer to Figure 1 and Figure 2 , as an implementation method of suction fastening: One end of both the first clamping plate 4 and the second clamping plate 5 is provided with an air extraction pipe 13, an air extraction port 14 is opened in the support groove 3, and the air extraction pipe 13 is communicated with the air extraction port 14. One end of the base 1 is provided with an air pump 15, and the air pump 15 cooperates with the air extraction pipe 13.

[0035] Specifically, when the first clamping plate 4 and the second clamping plate 5 cooperate to clamp and fix the laser nozzle, the external air pump 15 works to extract gas from the air extraction pipe 13, thereby extracting the air near the support groove 3 through the air extraction port 14, so that a vacuum state is formed between the air extraction port 14 and the laser nozzle. Using negative pressure, the laser nozzle is adsorbed, so that the laser nozzle is close to the inner wall of the support groove 3. In addition, after the processing is completed, the air pump 15 supplies air in the reverse direction to make the air extraction port 14 emit air, and the processing debris near the support groove 3 can be cleaned.

[0036] Please refer to Figure 1, As a further implementation of the exhaust pipe: One end of the base 1 is provided with a manifold 16. One end of the manifold 16 is fitted with an air pump 15, and the other end is provided with a gas guide hose 17. Multiple groups of gas guide hoses 17 are provided and are connected to the exhaust pipe 13.

[0037] Specifically, through the manifold 16 as a transfer, multiple gas guide hoses 17 are connected to different exhaust pipes 13, enabling multiple exhaust pipes 13 to cooperate with the air pump 15 through the manifold 16. Through the air pump 15, multiple exhaust pipes 13 can be evacuated simultaneously. Additionally, the material of the gas guide hose 17 is relatively soft, allowing it to deform to adapt to the displacement of the first clamping plate 4 and the second clamping plate 5.

[0038] Please refer to Figures 2-4 , As a further implementation of the first clamping plate: A first sliding opening 18 is formed on the base 1. A first sliding frame 19 is provided in the first sliding opening 18. The first sliding frame 19 is slidably fitted with the first sliding opening 18, and the first clamping plate 4 is slidably fitted with the sliding block 6 through the first sliding frame 19.

[0039] Specifically, when the sliding block 6 moves, it will drive the first sliding frame 19 to move. The first sliding frame 19 passes through the first sliding opening 18 and drives the first clamping plate 4 to move.

[0040] Please refer to Figures 2-5 , As a further implementation of the second clamping plate: A second sliding opening 20 is formed on the base 1. The second sliding opening 20 is communicated with the sliding cavity 8. The outer end of the second clamping plate 5 is provided with a second sliding frame 21. The second sliding frame 21 is slidably fitted with the second sliding opening 20, and the other end of the second sliding frame 21 is connected to the sliding strip 9.

[0041] Specifically, when the second clamping plate 5 moves, it will drive the second sliding frame 21 to move. The second sliding frame 21 passes through the second sliding opening 20 and extends into the sliding cavity 8, connecting with the sliding strip 9 and driving the sliding strip 9 to move.

[0042] Please refer to Figures 2-5 , As a further implementation of the sliding frame: Limiting sliders 22 are provided on both the first sliding frame 19 and the second sliding frame 21. Limiting sliding grooves 23 are formed in both the first sliding opening 18 and the second sliding opening 20.

[0043] Specifically, when the first sliding frame 19 and the second sliding frame 21 move, the limiting sliders 22 will cooperate with the limiting sliding grooves 23. The limiting sliding grooves 23 will guide the movement of the limiting sliders 22, enabling the first sliding frame 19 to slide stably in the first sliding opening 18 and the second sliding frame 21 to slide stably in the second sliding opening 20.

[0044] Please refer to Figure 3, as a further implementation of the sliding bar: a receiving groove 24 is provided in the sliding cavity 8, the pressing block 11 is arranged in the receiving groove 24, and an anti-slip pad 25 is provided at the contact end of the pressing block 11 and the sliding bar 9.

[0045] Specifically, when fixing the laser nozzle, the pressing block 11 will be received in the receiving groove 24 without affecting the movement of the sliding bar 9. When the pressing block 11 fixes the sliding bar 9, it will contact the sliding bar 9 through the anti-slip pad, provide a large friction coefficient through the anti-slip pad, and prevent the movement of the sliding bar 9 under pressure.

[0046] Please refer to Figure 2 , as a further implementation of the sliding bar: a marking rod 26 is provided at one end of the sliding bar 9 close to the buffer spring 10, a marking head 27 is provided on the base 1, and the marking rod 26 passes through the second sliding opening 20 and cooperates with the marking head 27.

[0047] Specifically, when the sliding bar 9 moves and compresses the buffer spring 10, it will drive the marking rod 26 to move. The upper end of the marking rod 26 passes out of the second sliding opening 20 for easy observation. Workers use the marking head 27 as a reference to observe the movement state between the marking rod 26 and the marking head 27, so as to determine the state of the buffer spring 10 and judge the pressing situation of the second clamping plate 5 on the laser nozzle.

[0048] In summary, when the overall device is in use or operation:

[0049] When using the device, the overall structure is supported by the base 1, the laser nozzle is placed in the support groove 3, and the laser nozzle is positioned and fixed through the support of the support plate 2 for processing. When installing the laser nozzle, a certain gap is left between the first clamping plate 4 and the second clamping plate 5, which is larger than the width of the laser nozzle. Then the laser nozzle is placed between the support grooves 3 of the first clamping plate 4 and the second clamping plate 5, and the laser nozzle is supported by the support groove 3. Then the adjusting screw rod 7 is controlled. By rotating the adjusting screw rod 7, the adjusting screw rod 7 cooperates with the sliding block 6 to provide power for the movement of the sliding block 6. When the sliding block 6 moves, it will drive the first sliding frame 19 to move. The first sliding frame 19 passes through the first sliding opening 18 and drives the first clamping plate 4 to move closer to the second clamping plate 5, so as to cooperate with the second clamping plate 5 to clamp the laser nozzle, and the distance gap between the first clamping plate 4 and the second clamping plate 5 is adjusted to adapt to laser nozzles of different sizes for positioning and fixing.

[0050] When the first clamping plate 4 and the second clamping plate 5 cooperate, the pressure generated by the movement of the first clamping plate 4 is transmitted to the second clamping plate 5 through the laser nozzle. The second sliding bracket 21 passes through the second sliding opening 20 and extends into the sliding cavity 8, where it is connected to the sliding bar 9. The pressurized second clamping plate 5 drives the sliding bar 9 to move. The pressing block 11 is received in the receiving groove 24 and does not affect the movement of the sliding bar 9. The movement of the sliding bar 9 is supported by the buffer spring 10. As the sliding bar 9 moves, the buffer spring 10 compresses, increasing the pressure exerted on the sliding bar 9, causing the second clamping plate 5 to cooperate with the first clamping plate 4 to clamp the laser nozzle. Excessive pressure is transmitted to the buffer spring 10 and absorbed by it to prevent damage to the laser nozzle caused by excessive pressure. As the buffer spring 10 contracts to a certain extent, when the sliding bar 9 moves and compresses the buffer spring 10, it drives the identification rod 26 to move. The upper end of the identification rod 26 passes through the second sliding opening 20, facilitating observation. Workers use the identification head 27 as a reference to observe the movement state between the identification rod 26 and the identification head 27, thereby determining the state of the buffer spring 10 and judging the pressure exerted by the second clamping plate 5 on the laser nozzle, and can determine that the laser nozzle is clamped and positioned. At this time, control the driving screw 12. By rotating the driving screw 12 and cooperating with the base 1, the driving screw 12 moves inward along the base 1. The pressing block 11 contacts the sliding bar 9 through the anti-slip pad. The anti-slip pad provides a large coefficient of friction and adheres tightly under pressure, thereby providing a large frictional force to prevent the movement of the sliding bar 9, driving the pressing block 11 to move towards the sliding bar 9, pressing tightly on the sliding bar 9, and fixing the sliding bar 9, thus ensuring the fixation of the second clamping plate 5. In addition, when the first sliding bracket 19 and the second sliding bracket 21 move, they cooperate through the limit slider 22 and the limit sliding groove 23. The limit sliding groove 23 guides the movement of the limit slider 22, enabling the first sliding bracket 19 to slide stably in the first sliding opening 18 and the second sliding bracket 21 to slide stably in the second sliding opening 20.

[0051] In addition, when the first clamping plate 4 and the second clamping plate 5 cooperate to clamp and fix the laser nozzle, the external air pump 15 operates. Through the manifold 16 as a transfer, multiple air guide hoses 17 are connected to different suction pipes 13, enabling multiple suction pipes 13 to cooperate with the air pump 15 through the manifold 16. Through the air pump 15, air can be simultaneously pumped out from multiple suction pipes 13, extracting gas from the suction pipes 13. Thereby, air near the support groove 3 is sucked through the suction port 14, creating a vacuum state between the suction port 14 and the laser nozzle. Using negative pressure, the laser nozzle is adsorbed, causing the laser nozzle to adhere tightly to the inner wall of the support groove 3. In addition, after processing is completed, the air pump 15 supplies air in the reverse direction, causing the suction port 14 to discharge air, which can clean the processing debris near the support groove 3. In addition, the air guide hose 17 is made of a soft material and can deform to adapt to the displacement of the first clamping plate 4 and the second clamping plate 5.

[0052] Among all the solutions mentioned above, for the connection between two components, welding, connection by bolts and nuts, connection by bolts or screws, or other well-known connection methods can be selected according to the actual situation, which will not be elaborated one by one here. For those mentioned above that involve fixed connection, welding is preferably considered. Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
