Description

Technical Field

[0001] This utility model relates to the field of laser processing technology, specifically to a material feeding mechanism for a laser cutting machine. Background Technology

[0002] With the development of society and economy, there are more and more large-format laser cutting equipment on the market. The main material to be cut is sheet metal. When laser cutting sheet metal, a material feeding mechanism of a laser cutting machine is required.

[0003] For example, the authorization notice number is "CN 215200241" A top-feeding mechanism for a laser cutting machine, described in this application, uses a first lifting device to drive a first lifting plate, which in turn drives a support rod and a universal ball to rise and fall. When material needs to be fed, the first lifting device is raised, so that the apex of the universal ball is higher than the top surface of the serrated worktable. The sheet material is then fed in, making contact with the universal ball. At this point, the top-feeding mechanism as a whole supports the sheet material, and the universal ball allows the sheet material to be easily moved while ensuring a smooth surface. After the sheet material is moved to the designated position, the first lifting device descends, causing the universal ball to move so that the apex of the universal ball is lower than or equal to the top surface of the serrated worktable, allowing the sheet material to fall onto the serrated worktable. The sheet material is then supported by the serrated worktable. Therefore, the top-feeding mechanism for a laser cutting machine proposed in this application has the beneficial effects of facilitating material feeding and ensuring the surface quality of the sheet material. However, since the device supports the sheet material through the serrated worktable, the operation is relatively cumbersome when the operator needs to fix and install the serrated worktable, which reduces the working efficiency of the device. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the device supports the sheet metal through a serrated worktable, which requires operators to fix and install the serrated worktable, making the operation cumbersome and reducing the working efficiency of the device. Therefore, this invention proposes a material-lifting mechanism for a laser cutting machine.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a material feeding mechanism for a laser cutting machine, including a support plate and a first housing. The inner wall of the support plate is slidably connected to the first housing. The first housing is provided with a snap-fit ​​device inside. A second housing is fixedly connected to the upper end of the first housing. Multiple hydraulic cylinders are fixedly connected to the inner wall of the second housing.

[0007] Preferably, the locking device includes a motor and a worm gear. The motor is fixedly connected to the first housing via a bracket. The output shaft of the motor is fixedly connected to the worm gear. The outer wall of the worm gear meshes with a worm wheel. The rotating shaft of the worm wheel is fixedly connected to a turntable. Round rods are fixedly connected to both sides of the turntable. The outer wall of the round rods is slidably connected to a slide rod. A locking block is fixedly connected to the outer side of the slide rod.

[0008] Preferably, the motor output shaft is rotatably connected to the first housing via a bearing, and the outer wall of the slide rod is slidably connected to the first housing.

[0009] Preferably, a support block is fixedly connected to the upper end of the hydraulic cylinder.

[0010] Preferably, a omnidirectional ball is installed on the upper end of the support block.

[0011] Preferably, a worktable is fixedly connected to the upper end of the second housing.

[0012] The present invention provides a material feeding mechanism for a laser cutting machine, which has the following advantages: Through the cooperation of the locking device and the support plate, the output shaft of the starter motor rotates, driving the worm gear to rotate. Due to the characteristics of the worm gear, the rotation of the worm gear drives the worm wheel to rotate, which in turn drives the turntable to rotate synchronously. The rotation of the turntable drives the round rod to rotate, which in turn drives the slide rod to move inward. The slide rod drives the locking block to move synchronously. The locking block moves inward and, through the engagement of the locking block with the groove on the inner wall of the support plate, controls the disassembly or installation of the worktable from the surface of the laser cutting machine. This facilitates quick disassembly, installation, and maintenance of the worktable by the operator, improving work efficiency. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] See attached document Figure 1-6 In this embodiment, a top-loading mechanism for a laser cutting machine includes a support plate 1 and a first housing 3. The support plate 1 is fixed to the surface of the laser cutting machine, and the inner wall of the support plate 1 is slidably connected to the first housing 3. The first housing 3 is placed inside a groove processed on the surface of the support plate 1. A snap-fit ​​device 2 is provided inside the first housing 4. A second housing 4 is fixedly connected to the upper end of the first housing 3. A plurality of hydraulic cylinders 5 are fixedly connected to the inner wall of the second housing 4. The hydraulic cylinders 5 can meet the working requirements according to actual needs.

[0022] A support block 6 is fixedly connected to the upper end of the hydraulic cylinder 5. The movement of the extension end of the hydraulic cylinder 5 drives the support block 6 to move. A universal ball 7 is installed on the upper end of the support block 6. The universal ball 7 can support the sheet material. A worktable 8 is fixedly connected to the upper end of the second box 4. The sheet material is placed on the surface of the worktable 8.

[0023] See attached document Figure 1-5 The snap-fit ​​device 2 includes a motor 201 and a worm gear 202. The motor 201 is fixedly connected to the first housing 3 via a bracket. The output shaft of the motor 201 is fixedly connected to the worm gear 202. The rotation of the output shaft of the motor 201 drives the worm gear 202 to rotate. Due to the characteristics of the worm gear, the rotation of the worm gear 202 drives the worm wheel 203 to rotate. The outer wall of the worm gear 202 meshes with the worm wheel 203. The rotating shaft of the worm wheel 203 is fixedly connected to a turntable 204. The rotation of the worm wheel 203 drives the turntable 204 to rotate synchronously. Both sides of the turntable 204 are fixed. A round rod 205 is connected to the turntable 204. The rotation of the turntable 204 drives the round rods 205 on both sides to rotate. The outer wall of the round rod 205 is slidably connected to the slide rod 206. The round rod 205 moves inside the slide rod 206 while driving the slide rod 206 to move. A locking block 207 is fixedly connected to the outside of the slide rod 206. The movement of the slide rod 206 drives the locking block 207 to move synchronously. The output shaft of the motor 201 is rotatably connected to the first housing 4 through the bearing. The outer wall of the slide rod 206 is slidably connected to the first housing 3. The first housing 3 restricts the position and movement track of the slide rod 206.

[0024] Working principle:

[0025] The operator uses the snap-fit ​​device 2 to fix the first box 3 to the surface of the laser cutting machine. The operator places the sheet material on the worktable 8 and cuts the sheet material with the laser cutting machine. When it is necessary to lift the material, the operator controls the extension end of the hydraulic cylinder 5 to extend and drive the support block 6 to move upward. The upward movement of the support block 6 drives the universal ball 7 to move synchronously. The upward movement of the universal ball 7 lifts the sheet material, so that the sheet material can be pulled above the universal ball 7, thus completing the lifting process of the sheet material.

[0026] Maintenance process for the workbench:

[0027] When the external power supply of the motor is turned on, the output shaft of the motor 201 rotates, driving the worm gear 202 to rotate. Due to the characteristics of the worm gear, the rotation of the worm gear 202 drives the worm wheel 203 to rotate, which in turn drives the turntable 204 to rotate synchronously. The rotation of the turntable 204 drives the round rod 205 to rotate, which in turn drives the slide rod 206 to move inward. The slide rod 206 drives the locking block 207 to move synchronously. The locking block 207 moves inward. When the locking block 207 is no longer inserted into the support plate 1, the operator can remove the worktable 8 from the surface of the laser cutting machine for maintenance. After the maintenance is completed, the first housing 3 is inserted into the groove inside the support plate 1. By controlling the above process and reversing the operation, the worktable 8 can be reset. By inserting the locking block 207 into the groove at different heights, different position heights can be adjusted to complete the maintenance process of the worktable.
