Description

Technical Field

[0001] This utility model relates to the field of laser drilling technology, and in particular to a laser drilling device for a lifting table sleeve. Background Technology

[0002] The sleeve of a height-adjustable desk often needs to be fitted with screws, nuts and other fixing components to connect the desk legs, desktop or other accessories. Therefore, holes need to be drilled in the corresponding positions on the sleeve to secure these components. For electric height-adjustable desks, holes need to be drilled in the sleeve so that the power cord or data cable can pass through smoothly to enable power supply or data connection for the devices on the desktop. Therefore, drilling holes in the sleeve of a height-adjustable desk is a common industrial requirement.

[0003] Currently, Chinese patent CN206883025U discloses a laser drilling device for pipe fittings. It includes a housing fixed on a base plate, a laser printer mounted on the housing, a clamping device on the left side of the housing, and a driving mechanism on the right side of the housing. The clamping device and the driving mechanism are connected by a temperature-sensing sleeve placed inside the housing. The temperature-sensing sleeve has a plurality of laser transmission holes uniformly formed in the middle, and the laser printer is directly facing the laser transmission holes.

[0004] Although this laser drilling device specifically designed for pipe fittings eliminates the need to remove and re-fix the pipe fittings during the drilling process, thus improving both drilling efficiency and accuracy, it lacks a tool positioning detection function. Therefore, it cannot detect in real-time whether the tool has reached its position or completely penetrated the outer wall of the workpiece during the drilling process. Utility Model Content

[0005] In view of the above situation and to overcome the defects of the prior art, the purpose of this utility model is to provide a laser drilling device for lifting table sleeves, which realizes the function of real-time detection of whether the laser drilling is in place by equipping a set of vertical positioning detection modules.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A laser drilling device for a height-adjustable table sleeve includes:

[0008] The device workstation plate has a lifting table sleeve installed above it.

[0009] A laser drilling device is provided, which is located on the upper end of the workstation plate and directly above one end of the lifting table sleeve. The laser drilling device includes a laser drilling cutter, a cutter lifting block, a side wall connecting block, and a synchronous lifter. The cutter lifting block is located on one side of the laser drilling cutter, the side wall connecting block is located on the side wall of the cutter lifting block, and the synchronous lifter is located at the lower end of the side wall connecting block. The bottom surface of the synchronous lifter is at the same level as the bottom surface of the laser drilling cutter.

[0010] The positioning detection base plate is equipped with a drilling positioning sensor at its upper end. The drilling positioning sensor is located directly below the synchronous lifter, and the sensing end face of the upper part of the drilling positioning sensor is at the same horizontal plane as the lower end face of the drilling hole of the lifting table sleeve.

Support frames are provided on both sides of the upper end of the device station plate. A stabilizing plate is provided at the upper end of the support frames. The stabilizing plate is located on the back of the vertical linear module.

[0012] Furthermore, a sleeve fixing device is provided on the outer side of the lifting table sleeve.

[0025] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figure 1 To be continued Figure 4 The detailed description of the embodiments will make this clear. All structural details mentioned in the following embodiments are based on the accompanying drawings.

[0026] Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings.

[0027] A laser drilling device 2 for a height-adjustable table sleeve includes:

[0028] The device workstation plate 1 has a lifting table sleeve on top of it. The lifting table sleeve is the main object that needs to be laser-drilled in this embodiment. The lifting table sleeve often needs to be connected to the table legs, tabletop or other accessories by installing screws, nuts and other fixing components. Therefore, holes need to be drilled in the corresponding positions on the sleeve to fix these components firmly. For electric lifting tables, holes need to be drilled in the sleeve so that wires or data cables can pass through smoothly to realize the power supply or data connection of the devices on the tabletop. Therefore, drilling on the lifting table sleeve is a common industrial requirement.

[0029] The laser drilling device 2 is located on the upper end of the workstation plate 1 and is directly above one end of the lifting table sleeve. The laser drilling device 2 includes a laser drilling cutter 201, a cutter lifting block 202, a side wall connecting block 203, and a synchronous lifter 204. The cutter lifting block 202 is located on one side of the laser drilling cutter 201, the side wall connecting block 203 is located on the side wall of the cutter lifting block 202, and the synchronous lifter 204 is located at the lower end of the side wall connecting block 203. The bottom surface of the synchronous lifter 204 is at the same level as the bottom surface of the laser drilling cutter 201.

[0030] The positioning detection base plate 3 is also set on the upper end of the device workstation plate 1. A drilling positioning sensor 301 is set on the upper end of the positioning detection base plate 3. The drilling positioning sensor 301 is set directly below the synchronous lifter 204. The upper sensing end face of the drilling positioning sensor 301 is at the same level as the lower end face of the drilling hole of the lifting table sleeve.

[0031] A vertical linear module 205 is provided on one side of the tool lifting block 202. The vertical linear module 205 is located at the upper end of the device station plate 1. Support frames 4 are provided on both sides of the upper end of the device station plate 1. A stabilizing plate 5 is provided at the upper end of the support frames 4. The stabilizing plate 5 is located on the back of the vertical linear module 205. In the above structure, the vertical linear module 205 driven by the servo motor can accurately control the movement of the laser drilling tool 201 in the vertical direction. The support frames 4 on both sides of the device station plate 1 and the stabilizing plate 5 at the top form a stable structure, which can effectively suppress the vibration of the vertical linear module 205 during operation, enhance its control accuracy, and prevent the laser focus of the laser drilling tool 201 from shifting due to vibration during drilling operations, resulting in hole distortion.

[0032] The laser drilling tool 201 is controlled by the vertical linear module 205 to perform lifting and adjusting movements. When the lifting table sleeve is sent to the work station, the laser drilling tool 201 descends and drills holes in the surface of the lifting table sleeve. During this process, the synchronous lifter 204 follows the laser drilling tool 201 and descends synchronously. When the laser drilling tool 201 penetrates the lower end of the lifting table sleeve, the synchronous lifter 204 touches the drilling position sensor 301. If the synchronous lifter 204 does not touch the drilling position sensor 301 until the drilling ends, then the laser drilling tool 201 has not completely penetrated the lower wall of the lifting table sleeve, that is, the tool has not reached the preset depth, and the current drilling action fails.

[0033] A sleeve fixing device 6 is provided on the outside of the lifting table sleeve. The sleeve fixing device 6 includes a connecting sleeve 601, a top fixing member 602, and a locking device 603. The connecting sleeve 601 is located on the outside of the end of the lifting table sleeve to be drilled. The top fixing member 602 is located on the upper end of the connecting sleeve 601. The locking device 603 is threaded into the top fixing member 602. The lower part of the locking device 603 penetrates the upper wall of the connecting sleeve 601 and abuts against the top of the lifting table sleeve. The locking device 603 is screwed into the top fixing member 602 by threads and directly abuts against the top of the lifting table sleeve. After being locked, the lifting table sleeve moves horizontally with the connecting sleeve 601, which can also prevent the workpiece from shaking during processing.

[0034] The connecting sleeve 601 has extension plates 604 integrally formed with the connecting sleeve 601 on both sides. The top fixing component 602 includes a fixing rod 6021, a fixing platform plate 6022, and an installation tube 6023. There are two sets of fixing rods 6021, and the fixing rods 6021 are located at the upper end of the extension plate 604. The fixing platform plate 6022 is located at the upper end of the fixing rods 6021. The installation tube 6023 is located in the middle of the fixing platform plate 6022. The locking device 603 is located in the installation tube 6023.

[0035] A moving block 605 is provided at the lower end of the outer side of the extension plate 604, and a horizontal linear module 606 is provided at the lower end of the moving block 605. The horizontal linear module 606 is driven by a servo motor. Since the extension plate 604 is provided on both sides of the connecting sleeve 601, there are two sets of horizontal linear modules 606 in this embodiment. The parameters of the two sets of horizontal linear modules 606 are set the same, and they work together to precisely control the movement of the lifting table sleeve and the entire sleeve fixing device 6 in the horizontal direction.

[0036] A synchronous moving block 7 is provided at the lower end of one side extension plate 604. An auxiliary rail 8 located on the upper end of the device workstation plate 1 is provided at the lower end of the synchronous moving block 7. The synchronous moving block 7 and the auxiliary rail 8 are slidably assembled. A synchronous horizontal mover 9 is provided on one side of the synchronous moving block 7. A transport position sensor 302 is also provided at the upper end of the position detection base plate 3. The synchronous horizontal mover 9 is positioned directly opposite the transport position sensor 302. When the lifting table sleeve is sent to the workstation, the transport position sensor 302 detects the position signal.

[0037] The above description is a further detailed explanation of the present utility model in conjunction with specific embodiments, and it should not be considered that the specific implementation of the present utility model is limited to this. For those skilled in the art to which the present utility model pertains and related fields, any extensions, operation methods, and data substitutions made based on the technical solution concept of the present utility model should fall within the protection scope of the present utility model.
