Description

Technical Field

[0001] This utility model relates to the field of laser cutting technology, specifically to an automatic point pressing device for mechanical engraving machines. Background Technology

[0002] A laser cutting machine focuses a laser beam emitted from a laser source into a high-power-density beam through an optical path system. This beam irradiates 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. Laser cutting uses an invisible beam of light instead of a traditional mechanical blade, offering advantages such as high precision, fast cutting speed, no limitation on cutting patterns, automatic layout to save material, smooth cuts, and low processing costs. It is gradually improving upon or replacing traditional metal cutting equipment.

[0003] In the existing technology, existing laser cutting and engraving equipment lacks a dedicated device for effectively clamping the cut sheet after cutting. After cutting, it usually relies on the initial fixing method, such as simple suction cup adsorption or mechanical gripper to maintain the state of the sheet. However, these methods are affected by laser impact and thermal effects during the cutting process, and the fixing effect is greatly reduced. After cutting, the sheet may shift or warp due to its own weight, internal airflow disturbance of the equipment, or even slight vibration, which greatly affects the quality of the product and the accuracy of subsequent processing.

[0004] In light of this, we have launched an automatic pressure device for mechanical engraving machines. Utility Model Content

[0005] The purpose of this invention is to provide an automatic pressure device for mechanical engraving machines to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic point-pressing device for a mechanical engraving machine, comprising: a side plate, a connecting plate, and a positioning plate;

[0007] A carving machine is provided on one side of the side plate, and a carving head is provided at the output end of the carving machine;

[0008] The connecting plate is disposed on one side of the surface of the side plate, and the connecting plate and the side plate are fixedly disposed therebetween. A movable plate is provided on the side of the connecting plate.

[0009] The positioning plate is disposed on the side of the moving plate, and the positioning plate and the moving plate are fixedly disposed together, preferably by welding. A vertical plate is slidably attached to the surface of the positioning plate, and an L-shaped plate is disposed on the surface of the vertical plate.

[0010] A pressing mechanism is provided between the L-shaped plate and the upright plate. The cylinder A of the pressing mechanism drives the L-shaped plate, the inclined block and the pressing block to move downward so that the pressing block presses down on the plate.

[0011] Preferably, the pressing mechanism includes a positioning seat connected to one side of the top of the L-shaped plate, the positioning seat being fixedly installed with the L-shaped plate support, a cylinder A connected to the surface of the upright plate by bolts, a guide rail A connected to one side of the surface of the upright plate, the guide rail A being fixedly installed with the upright plate, a guide seat A slidably mounted on the surface of the guide rail A, the L-shaped plate connected to the surface of the guide seat A, the guide seat A being fixedly installed with the L-shaped plate, the output end of the cylinder A connected to the positioning seat, an inclined block connected to one side of the L-shaped plate by bolts, and a pressing block connected to the bottom of the inclined block, the pressing block being fixedly installed with the inclined block.

[0012] Preferably, the surface of the positioning plate is connected to a limiting block, the surface of the limiting block is slidably connected to a limiting seat, and the limiting seat is connected to the upright plate.

[0013] Preferably, a cylinder B is connected to the surface of the connecting plate, and the cylinder B is connected to the surface of the moving plate, with the cylinder B and the moving plate being detachable.

[0014] Preferably, a support base is connected to the surface of the connecting plate, the support base and the connecting plate are fixedly connected, and the output end of the cylinder B is connected to the surface of the support base.

[0016] Preferably, the surface of the connecting plate is provided with a slot for the movement of cylinder B, and the slot and the connecting plate are integrally formed.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] (1) Extend through the output end of cylinder A to pull the positioning seat connected to it. Since the positioning seat is connected to the top side of the L-shaped plate and the L-shaped plate is connected to the guide seat A, and the guide seat A slides on the guide rail A, the L-shaped plate moves down along the guide rail A under the thrust of cylinder A. As the L-shaped plate moves down, the inclined block connected to one side and the pressure block at the bottom also move down synchronously. When the pressure block contacts the plate, it continues to press down. Relying on the friction between the pressure block and the plate, the plate is pressed tightly and will not be allowed to move after cutting. Then the engraving machine drives the engraving head to move up.

[0019] (2) The laser cutting and engraving machine enters the work preparation state. After the position of the engraving machine is adjusted, the engraving machine is started. The engraving machine works, and its output end drives the engraving head to rotate at high speed to engrave or cut the board.

[0020] (3) After the cylinder B is started, its output end pushes the support seat. Since the support seat is connected to the moving plate, and the guide rail B connected to the surface of the connecting plate is provided with a guide seat B connected to the moving plate, the extension and retraction of the cylinder B drives the moving plate to move horizontally along the guide rail B. The positioning plate, vertical plate, L-shaped plate and pressing mechanism and other components will move synchronously with it, thereby realizing the precise adjustment of the pressing block in the horizontal direction to meet the needs of different processing positions.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-6 This utility model provides a technical solution: an automatic point pressing device for a mechanical engraving machine, comprising: a side plate 1, an engraving machine 2 disposed on one side of the side plate 1, and an engraving head 3 disposed at the output end of the engraving machine 2;

[0030] A connecting plate 9 is disposed on one side of the surface of the side plate 1. The connecting plate 9 is fixedly disposed with the side plate 1. A movable plate 12 is provided on the side of the connecting plate 9.

[0031] Positioning plate 8 is disposed on the side of moving plate 12. Positioning plate 8 and moving plate 12 are fixedly disposed together, preferably by welding. A vertical plate 18 is slidably connected to the surface of positioning plate 8. An L-shaped plate 7 is disposed on the surface of vertical plate 18.

[0032] A pressing mechanism is provided between the L-shaped plate 7 and the upright plate 18. The cylinder A6 of the pressing mechanism drives the L-shaped plate 7, the inclined block 5 and the pressing block 4 to move downward so that the pressing block 4 presses down on the plate.

[0033] The pressing mechanism includes a positioning seat 21 connected to one side of the top of the L-shaped plate 7, the positioning seat 21 being fixedly installed with the L-shaped plate 7 support, a cylinder A6 connected to the surface of the upright plate 18 by bolts, a guide rail A19 connected to one side of the surface of the upright plate 18, the guide rail A19 being fixedly installed with the upright plate 18, a guide seat A20 slidably attached to the surface of the guide rail A19, the L-shaped plate 7 being connected to the surface of the guide seat A20, the guide seat A20 being fixedly installed with the L-shaped plate 7, the output end of the cylinder A6 being connected to the positioning seat 21, an inclined block 5 connected to one side of the L-shaped plate 7 by bolts, and a pressing block 4 connected to the bottom of the inclined block 5, the pressing block 4 being fixedly installed with the inclined block 5.

[0034] The surface of the positioning plate 8 is connected to a limiting block 16, the surface of the limiting block 16 is slidably connected to a limiting seat 17, and the limiting seat 17 is connected to the upright plate 18.

[0035] A cylinder B13 is connected to the surface of the connecting plate 9. The cylinder B13 is connected to the surface of the moving plate 12, and the cylinder B13 and the moving plate 12 are detachable.

[0036] The surface of the connecting plate 9 is connected to the support base 10, and the support base 10 and the connecting plate 9 are fixedly connected, and the output end of the cylinder B13 is connected to the surface of the support base 10.

[0037] In the first embodiment, a guide rail B14 is connected to the surface of the connecting plate 9, and the guide rail B14 is fixedly disposed with the connecting plate 9. A guide seat B15 is connected to the surface of the guide rail B14, and the guide seat B15 is connected to the surface of the moving plate 12, so that the guide seat B15 can drive the moving plate 12 to be limited. The guide rail B14 and the guide seat B15 are a set.

[0038] In the second embodiment, the guide rail B14 and the guide seat B15 are two sets respectively.

[0039] The surface of the connecting plate 9 is provided with a slot 22 for the movement of the cylinder B13, and the slot 22 and the connecting plate 9 are integrally formed.

[0040] Specifically, when using it, place the board to be processed on the worktable. At this time, the laser cutting and engraving machine 2 will enter the work preparation state. After the position of the engraving machine 2 is adjusted, start the engraving machine 2. The engraving machine 2 will work, and its output end will drive the engraving head 3 to rotate at high speed to engrave or cut the board.

[0041] When the cutting of the plate is completed, the pressing mechanism starts to work. The cylinder A6 starts and the output end of the cylinder A6 extends to pull the positioning seat 21 connected to it. Since the positioning seat 21 is connected to the top side of the L-shaped plate 7 and the L-shaped plate 7 is connected to the guide seat A20, and the guide seat A20 slides on the guide rail A19, the L-shaped plate 7 moves down along the guide rail A19 under the pushing force of the cylinder A6. As the L-shaped plate 7 moves down, the inclined block 5 connected to one side and the pressing block 4 at the bottom also move down synchronously. When the pressing block 4 contacts the plate, it continues to press down. Relying on the friction between the pressing block 4 and the plate, the plate is pressed tightly. Then the engraving machine 2 drives the engraving head 3 to move up.

[0042] Throughout the entire processing, the limiting seat 17 is connected to the upright plate 18. When the upright plate 18 moves with the moving plate 12 or rises and falls due to the action of the pressing mechanism, the limiting seat 17 slides along the limiting block 16. This structure limits the range of motion of the upright plate 18 and ensures the stability and accuracy of its movement.

[0043] If the position of the pressure block 4 needs to be adjusted, the cylinder B13 will take effect. After the cylinder B13 is started, its output end will push the support seat 10. Since the support seat 10 is connected to the moving plate 12, and the guide rail B14 connected to the surface of the connecting plate 9 is provided with a guide seat B15 connected to the moving plate 12, the extension and retraction of the cylinder B13 will drive the moving plate 12 to move horizontally along the guide rail B14. At the same time, the slot 22 opened on the surface of the connecting plate 9 provides space for the movement of the cylinder B13, avoiding obstruction during its movement. When the moving plate 12 moves, the positioning plate 8, the upright plate 18, the L-shaped plate 7 and the pressing mechanism will move synchronously with it, thereby realizing the precise adjustment of the horizontal position of the pressure block 4 to meet the needs of different processing positions.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
