Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting machines, in particular to a loading and positioning structure of a laser cutting workbench. Background Art

[0002] In order to facilitate loading and unloading and avoid interference between the plate and the laser cutting head, the single workbench of some laser cutting machines is designed to be pull-out, that is, when loading and unloading, the workbench is pulled forward and away from the processing area of ​​the chassis. When the workbench moves to the set position, the loading positioning structure will limit the movement of the workbench to prevent the workbench from moving on its own and affecting loading and unloading and causing safety accidents. The existing loading positioning mechanism mainly drives the pin through the cylinder to be inserted into the socket on the workbench to limit the movement of the workbench. This loading positioning structure not only requires the supply of compressed air to cause energy consumption, but also requires the additional arrangement of air supply pipes. The initial manufacturing cost and future maintenance costs are high.

[0003] It can be seen that the existing technology still needs to be improved and enhanced. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a loading and positioning structure with a simple structure that can magnetically position and restrict the self-movement of a laser cutting workbench.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

A limiting piece is provided on one side of the pull-out workbench near the rear end. The base frame is provided with a bracket near the front end. The bracket is provided with magnetic shock-absorbing rubber that can produce magnetic attraction with the limiting piece.

[0007] As a further improvement of the above technical solution, the magnetic shock-absorbing rubber includes a magnet seat, a cylindrical magnet, an externally threaded protruding rod, and a shock-absorbing rubber head. A positioning hole for installing the cylindrical magnet is opened in the middle of the magnet seat, and a part of the cylindrical magnet extends out of the positioning hole. One end of the magnet seat is provided with the externally threaded protruding rod, and the other end is connected to the shock-absorbing rubber head that wraps the cylindrical magnet.

[0008] As a further improvement of the above technical solution, the bracket is an L-shaped plate, a mounting hole is opened on the vertical plate part of the L-shaped plate, and the external threaded protruding rod passes through the mounting hole and is fixed to the L-shaped plate by a nut.

[0009] As a further improvement of the above technical solution, a waist-shaped hole is provided on the flat plate portion of the L-shaped plate, and at least two threaded holes corresponding to the waist-shaped hole are provided on the base frame, and the screws pass through the waist-shaped holes and are connected to the corresponding threaded holes.

[0010] As a further improvement of the above technical solution, the base frame is provided with two guide rails extending in the front-to-back direction, and the bottom of the pull-out workbench is provided with sliders slidably connected to the corresponding guide rails.

[0011] As a further improvement of the above technical solution, the base frame is provided with a bracket located in front of the guide rail, and the bracket is provided with a rotatable supporting wheel for supporting the pull-out workbench.

[0012] As a further improvement of the above technical solution, the pull-out workbench includes a frame, a plurality of racks spanning and spaced apart on the frame, and a handle provided on the front end of the frame.

[0013] The beneficial effects of the present invention: Compared with the existing technology, the loading positioning structure provided by the present invention adopts a magnetic attraction positioning method combining magnetic shock-absorbing rubber and a limiter to replace the traditional cylinder-driven pin positioning, which not only eliminates the energy consumption caused by compressed air, but also eliminates the need for additional air supply pipelines, thereby reducing the initial manufacturing cost and subsequent maintenance cost.

DETAILED DESCRIPTION

[0019] The present invention provides a loading and positioning structure for a laser cutting worktable. To make the purpose, technical solution, and effects of the present invention more clear and explicit, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific examples described herein are intended only to illustrate the present invention and are not intended to limit the scope of protection of the present invention.

[0020] See also Figure 1-Figure 4 The utility model provides a loading and positioning structure for a laser cutting workbench, including a base frame 1, a pull-out workbench 2 slidably arranged on the base frame 1, a limiting member 3 is provided on one side of the pull-out workbench 2 near the rear end, and a bracket 40 is provided near the front end of the base frame 1, and a magnetic shock-absorbing rubber 5 is provided on the bracket 40 that can produce a magnetic attraction effect with the limiting member 3.

[0021] During the loading and unloading process, the staff pulls the pull-out workbench 2 out of the processing area of ​​the base frame 1. When the workbench moves to the set position, the limiter 3 is aligned with the magnetic shock-absorbing glue 5 on the bracket 40. Due to the magnetism of the magnetic shock-absorbing glue 5, the limiter 3 will be adsorbed on the magnetic shock-absorbing glue 5, thereby preventing the pull-out workbench 2 from further self-movement. The magnetic shock-absorbing glue 5 not only provides magnetic attraction, but also absorbs vibrations or impacts caused by external forces, protecting the pull-out workbench 2 from damage. After loading and unloading, the pull-out workbench 2 is manually pushed back to the processing area, and the limiter 3 can be separated from the magnetic shock-absorbing glue 5.

[0022] Compared with the existing technology, the loading positioning structure provided by the present invention adopts a magnetic attraction positioning method combining a magnetic shock-absorbing rubber 5 and a limiter 3 to replace the traditional cylinder-driven pin positioning, which not only eliminates the energy consumption caused by compressed air, but also eliminates the need for additional air supply pipelines, thereby reducing the initial manufacturing cost and subsequent maintenance cost. The magnetic attraction between the limiter 3 and the magnetic shock-absorbing rubber 5 realizes automatic positioning, ensuring that the pull-out workbench 2 is stable and motionless in the loading and unloading position, simplifying the operation process and improving work efficiency.

[0023] For details, see Figure 3As shown, the magnetic shock-absorbing rubber 5 includes a magnet base 51, a cylindrical magnet 52, an externally threaded protruding rod 53, and a shock-absorbing rubber head 54. A positioning hole 55 for mounting the cylindrical magnet 52 is provided in the middle of the magnet base 51. A portion of the cylindrical magnet 52 extends out of the positioning hole 55. One end of the magnet base 51 is provided with the externally threaded protruding rod 53, and the other end is connected to the shock-absorbing rubber head 54 that wraps the cylindrical magnet 52. The magnetic shock-absorbing rubber 5 is detachably mounted on the bracket 40 via the externally threaded protruding rod 53. The design of the cylindrical magnet 52 partially extending out of the positioning hole enhances the magnetic attraction of the magnetic shock-absorbing rubber 5, ensuring that the pull-out workbench 2 is firmly fixed in the set position. The shock-absorbing rubber head 54 wraps around the cylindrical magnet 52, which not only provides a good magnetic attraction effect, but also effectively absorbs external impact, protects the workbench from damage, and extends its service life.

[0024] In this embodiment, the bracket 40 is designed as an L-shaped plate with a mounting hole defined in the vertical plate portion. The externally threaded protruding rod 53 passes through the mounting hole and is secured to the L-shaped plate via a nut 41. Passing the externally threaded protruding rod 53 through the mounting hole and being secured via the nut 41 securely secures the magnetic shock-absorbing adhesive 5 to the bracket 40, making installation quick and easy.

[0025] Furthermore, the flat portion of the L-shaped plate is provided with a waist-shaped hole 42, and the base frame 1 is provided with at least two threaded holes corresponding to the waist-shaped holes 42. Screws 43 are inserted through the waist-shaped holes 42 and then connected to the corresponding threaded holes. The design of the waist-shaped holes 42 allows the L-shaped plate to move horizontally within a certain range, thereby adjusting the position of the magnetic shock-absorbing adhesive 5 relative to the limiter 3. When the position of the magnetic shock-absorbing adhesive 5 needs to be adjusted or replaced, it is only necessary to loosen the screws 43, move the L-shaped plate to the appropriate position, and then tighten it again.

[0026] In this embodiment, the limiting member 3 is specifically an iron plate or an iron block, which can generate magnetic attraction with the magnetic shock-absorbing rubber 5 .

[0027] To ensure smooth forward and backward movement of the pull-out workbench 2, the base frame 1 is provided with two guide rails 61 extending in the forward and backward directions. The bottom of the pull-out workbench 2 is provided with sliders 62 slidably connected to the corresponding guide rails 61. The guide rails 61 are preferably aluminum-supported optical axis guide rails 61. The aluminum-supported optical axis guide rails 61 have excellent straightness and parallelism, and the friction coefficient between the aluminum-supported optical axis guide rails 61 and the sliders 62 is low, which reduces the resistance to the movement of the pull-out workbench 2, ensures the smoothness of the pull-out workbench 2 during forward and backward movement, and reduces vibration and noise caused by uneven movement.

[0028] Preferably, the base frame 1 is provided with a bracket 71 located in front of the guide rail 61, and the bracket 71 is provided with a rotatable supporting wheel 72 for supporting the pull-out workbench 2. The supporting wheel 72 can help share the weight of the pull-out workbench 2, reduce the load of the pull-out workbench 2 on the guide rail 61, ensure that the workbench is smooth and without shaking during movement, and improve stability during processing.

[0029] Preferably, the pull-out workbench 2 includes a frame 21, multiple racks 22 spaced across the frame 21, and a handle 23 at the front end of the frame 21. The multiple racks 22 spaced across the frame 21 evenly distribute the weight of the plates placed on the workbench, thereby increasing the workbench's load-bearing capacity. The handle 23 at the front end of the frame 21 allows the operator to easily pull or push the pull-out workbench 2, facilitating loading and unloading operations.
