Description

Technical Field

[0001] This utility model belongs to the field of laser cutting machine technology, specifically relating to a special tool for disassembling the pressure plate of a laser cutting machine. Background Technology

[0002] In practical applications of laser cutting equipment, the material table is a key component for carrying and transferring workpieces. Its main load-bearing structure consists of groups of grid plates. The grid plate groups are fixed to the material table frame by pressure plates and bolts to ensure the stability of workpiece placement and the reliability of the cutting process.

[0003] However, when the material platform is placed within the C-slot frame of the exchange table, due to structural space limitations, the fixing bolts of the material platform pressure plate are obstructed by the upper edge of the C-slot of the exchange table, creating a narrow and restricted operating space. The specific layout is as follows... Figure 10 As shown. Figure 10 In the diagram, 3.1 is the C-slot frame of the exchange workbench, 3.2 is the material platform, 3.2.1 is the grating pressure plate, and 3.2.2 is the grating assembly. This structural feature makes it difficult for operators to disassemble the pressure plate bolts using conventional tools, thus making the replacement of the grating extremely difficult.

[0004] Over time, the flatness of the grating plate will be affected by wear and deformation. If it is not replaced in time, it will directly lead to a decrease in workpiece positioning accuracy and affect the processing quality of laser cutting. In severe cases, the worn grating plate may even interfere with the laser cutting head, causing equipment damage. This not only increases maintenance costs but also affects production efficiency due to downtime, resulting in unnecessary economic losses for the company. Therefore, how to achieve convenient disassembly of the material table pressure plate bolts in a confined space has become an important issue for improving the maintenance convenience of laser cutting machines and ensuring stable equipment operation. Utility Model Content

[0005] The purpose of this utility model is to provide a special tool for disassembling the pressure plate of a laser cutting machine, so as to solve the problems existing in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a special tool for disassembling the pressure plate of a laser cutting machine, comprising a protective cover, a handle, a support frame, a transmission device, and an open sleeve; the protective cover is connected to the support frame, and the handle, transmission device, and open sleeve are all mounted on the support frame, with the handle connected to the input end of the transmission device and the open sleeve connected to the output end of the transmission device.

[0007] Preferably, the protective cover is integrally molded from transparent acrylic material to prevent external impurities from entering the transmission device and to prevent lubricating oil from splashing out.

[0008] Preferably, the handle includes a grip portion, a handle body, and a square connecting post; the grip portion is connected to the handle body via a bearing; the square connecting post is of standard size, with two retractable ball bearings at the bottom.

[0010] Preferably, the transmission device includes an input gear, a shaft retaining ring, a vertical transmission gear, a horizontal transmission gear, and an output gear; the central shaft of the input gear is fitted with a bearing in the support frame, and the end of the central shaft is provided with a snap ring groove, which connects to the support frame through the shaft retaining ring to achieve axial positioning, and its central shaft core is a standard slotted square hole; the vertical transmission gear has the same module as the input gear but has a larger number of teeth.

[0011] Preferably, the upper end of the open sleeve is a standard-sized square connecting post, with two retractable ball bearings at the lower part; its bottom is a standard hexagonal sleeve size and has a through groove, so that the bottom presents a four-sided slotted shape.

[0012] Preferably, the handle is connected to the slotted square hole of the input gear in the transmission device via a square connecting post; the open sleeve is connected to the slotted square hole of the output gear in the transmission device via the upper square connecting post.

[0015] Preferably, the transmission device uses bevel gears with different numbers of teeth for meshing transmission, with an overall transmission ratio of less than 1, and uses ultra-thin gears.

[0016] The beneficial effects of this utility model are as follows: This special tool, through its unique structural design, can smoothly complete the bolt disassembly operation within the limited working space where the bolts of the material table pressure plate are obstructed by the upper edge of the C-shaped groove of the exchange worktable. It adopts a bevel gear meshing transmission with a transmission ratio of less than 1, which amplifies the output torque. Combined with an ultra-thin gear to compress the height of the output end to adapt to confined spaces, it effectively solves the problem of traditional tools being unable to reach the bolts, making the replacement of the grating plate convenient and avoiding the decrease in cutting accuracy and equipment damage caused by the long-term neglect of grating plate replacement, significantly improving the maintainability of the laser cutting machine.

[0017] Meanwhile, the application of this tool reduces the time and labor costs of replacing the grating, and lowers the workload of operators. By replacing the grating in a timely manner, the stable operation and cutting accuracy of the laser cutting machine can be maintained, reducing production interruptions and product scrap caused by equipment failure or accuracy issues, thereby improving production efficiency, reducing enterprise production costs, and extending the service life of the laser cutting machine.

[0022] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings and preferred embodiments.

[0023] like Figure 1 As shown, a special tool for disassembling the pressure plate of a laser cutting machine is characterized by comprising a protective cover 1, a handle 2, a support frame 3, a transmission device 4, and an open sleeve 5; the protective cover 1 is connected to the support frame 3, the handle 2, the transmission device 4, and the open sleeve 5 are all mounted on the support frame 3, and the handle 2 is connected to the input end of the transmission device 4, and the open sleeve 5 is connected to the output end of the transmission device 4.

[0024] like Figure 2 As shown, the protective cover 1 is integrally molded from transparent acrylic material, possessing good strength and light transmittance. By tightly connecting the protective cover 1 to the support frame 3, it effectively blocks external impurities from entering the transmission device 4, while also preventing lubricating oil from splashing out of the transmission device, ensuring the cleanliness of the device's interior and stable operation.

[0025] like Figure 3 As shown, the handle 2 includes a grip portion 2-1, a handle body 2-2, and a square connecting post 2-3. The grip portion 2-1 and the handle body 2-2 are connected by bearings. The square connecting post 2-3 is of standard size, with two retractable ball bearings at the bottom. The grip portion 2-1 is made of wood and is ergonomically sized for comfortable gripping and force application by the operator. The handle body 2-2 is made of cast aluminum, which reduces overall weight while ensuring strength. The grip portion 2-1 and the handle body 2-2 are connected by bearings, allowing for relative rotation. The square connecting post 2-3 is of standard size and has two retractable ball bearings at the bottom. When inserted into the slotted square hole of the input gear 4-1 in the transmission device 4, the ball bearings can be engaged in the slot, achieving a secure fit and quick release between the handle 2 and the input gear 4-1.

[0026] like Figure 4 and Figure 5As shown, the support frame 3 includes a frame body 3-1, a bearing 3-2, and a retaining ring 3-3; the frame body 3-1 is formed by screwing together three machined mounting plates, and the mounting plates are provided with bearing mounting positions 3-4 and retaining ring mounting positions 3-5; the bearing 3-2 is mounted on the bearing mounting position 3-4 to support the gear and provide rotational motion for the gear; the retaining ring 3-3 is mounted on the retaining ring mounting position 3-5.

[0027] The bearing 3-2 is installed in the bearing mounting position 3-4 to support the gear in the transmission device 4 and enable it to rotate flexibly; the circlip 3-3 is installed in the circlip mounting position 3-5 to axially position the bearing 3-2 and prevent it from moving axially.

[0028] like Figure 6 and Figure 7 As shown, the transmission device 4 includes an input gear 4-1, a shaft retaining ring 4-2, a vertical transmission gear 4-3, a horizontal transmission gear 4-4, and an output gear 4-5. The central shaft of the input gear 4-1 is fitted with a bearing 3-2 in the support frame 3. The shaft retaining ring 4-2 is installed in the retaining ring groove at the end of the central shaft to achieve axial positioning of the input gear 4-1 and the support frame 3. The standard slotted square hole of its central shaft core can reliably fit with the square connecting post 2-3 of the handle 2.

[0029] The vertical transmission gear 4-3 has the same module as the input gear 4-1, but with a larger number of teeth, which can increase the transmission distance in the vertical direction; the horizontal transmission gear 4-4 is used to increase the output distance in the horizontal direction; the output gear 4-5 has a similar structure to the input gear 4-1, but its central axis is in the opposite direction, and its central axis core has a standard slotted square hole that can be fitted with the open sleeve 5.

[0030] The entire transmission device uses bevel gears with different numbers of teeth for meshing transmission, with an overall transmission ratio of less than 1. Furthermore, ultra-thin gears are selected, which can compress the height of the output end to fit the limited operating space of the machine tool.

[0031] like Figure 8 and Figure 9 As shown, the upper end of the open sleeve 5 is a standard-sized square connecting post, and the two retractable balls in the middle and lower part enable it to be firmly connected to the slotted square hole of the output gear 4-5 and achieve quick release; the bottom is a standard hexagonal sleeve size, and is provided with a through groove to form a four-sided slotted shape, which makes it easy to snap into the pressure plate bolt head.

[0032] In use, first insert the square connecting post 2-3 of handle 2 into the slotted square hole of input gear 4-1 and secure it firmly. Select a suitable open sleeve 5 according to the specifications of the pressure plate bolt, insert its upper square connecting post into the slotted square hole of output gear 4-5 and secure it firmly. Next, rotate handle 2 so that the opening direction of open sleeve 5 is consistent with the bolt head direction, and then put open sleeve 5 onto the pressure plate bolt. At this time, the operator rotates handle 2, and the torque is transmitted to input gear 4-1 through the handle. Input gear 4-1 meshes with vertical transmission gear 4-3, which drives horizontal transmission gear 4-4. Horizontal transmission gear 4-4 then transmits power to output gear 4-5. Since the transmission ratio of transmission device 4 is less than 1, the torque is proportionally amplified during transmission and finally acts on the pressure plate bolt through open sleeve 5 to achieve bolt disassembly. The protective cover 1 protects transmission device 4 from impurities and lubricating oil splashes throughout the process, while the support frame 3 provides stable support for each component, ensuring reliable and efficient transmission.

[0033] It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
