Description

Technical Field

[0001] This utility model belongs to the field of CNC machine tool protective equipment, specifically a CNC machine tool protective device. Background Technology

[0002] The protective devices for CNC machine tools mainly include protective doors, bellows covers, and aluminum curtains. These protective devices are key components used to protect the safety of operators and the machine tools, helping to maintain the accuracy and stability of the machine tools and significantly extending their service life.

[0003] Machine tool safety doors are devices specifically designed to protect CNC machine tools and their operators. They are typically made of metal or plastic and have good wear and corrosion resistance. These doors not only effectively prevent workpieces from flying out when the machine tool experiences a runaway, but also allow operators to easily observe the machining process in real time. However, the observation windows on these doors are usually made of transparent glass. In the event of a runaway, a broken tool or a workpiece flying out at high speed can impact the glass and cause it to break. Although current technologies use tempered glass or multi-layered insulated glass to increase impact resistance, safety hazards still exist after prolonged use when the glass develops cracks or wear.

[0004] In summary, this utility model provides a protective device for CNC machine tools to solve the above-mentioned problems. Utility Model Content

[0022] To better understand the technical content of this utility model, specific embodiments are described below in conjunction with the accompanying drawings. Various aspects of this utility model are described in this disclosure with reference to the accompanying drawings, which illustrate numerous illustrative embodiments. The embodiments of this disclosure are not necessarily defined to include all aspects of this utility model. It should be understood that the various concepts and embodiments described above, as well as those described in more detail below, can be implemented in any of many ways, because the concepts and embodiments disclosed in this utility model are not limited to any particular implementation. Furthermore, some aspects of this utility model can be used alone or in any suitable combination with other aspects disclosed in this utility model.

[0023] Example 1

[0024] like Figure 1-6As shown, this is the first embodiment of the present invention. This embodiment provides a CNC machine tool protective device, including a protective door assembly 1. The protective door assembly 1 includes a door panel 101 and tempered glass 102. The tempered glass 102 is embedded in the surface of the door panel 101. A protective component 2 is installed on the back of the door panel 101. The protective component 2 is used to protect the tempered glass 102. The protective component 2 includes a protective frame 201, a metal elastic mesh 202, a fixing cylinder 203, a mounting plate 204, a sliding rod 205, a first spring 206, a compression plate 207, and a second spring 208. The protective frame 201 and the metal elastic mesh 202 provide protection. The fixing cylinder 203, mounting plate 204, sliding rod 205, first spring 206, compression plate 207, and second spring 208 absorb impact forces. The mesh 202 is fixed to the inner cavity of the protective frame 201. One end of the fixing cylinder 203 is fixedly connected to the door panel 101. The mounting plate 204 is threadedly connected to the protective frame 201 by screws. The extrusion plate 207 and the second spring 208 are both installed in the inner cavity of the fixing cylinder 203. One end of the slide rod 205 extends into the inner cavity of the fixing cylinder 203 and is fixedly connected to the extrusion plate 207. The other end of the slide rod 205 is fixedly connected to the mounting plate 204. The two ends of the second spring 208 are fixedly connected to the inner wall of the fixing cylinder 203 and the extrusion plate 207, respectively. The first spring 206 is sleeved on the surface of the slide rod 205. The two ends of the first spring 206 are fixedly connected to the mounting plate 204 and the fixing cylinder 203, respectively. A cleaning component 3 is also installed on the back of the door panel 101. The cleaning component 3 is used to clean the tempered glass 102.

[0025] like Figure 1-6 As shown, the metal elastic mesh 202 and the protective frame 201 work together to intercept broken knives or workpieces. When the metal elastic mesh 202 is impacted, it drives the protective frame 201 closer to the door panel 101. When the protective frame 201 moves, it pushes the sliding rod 205 into the inner cavity of the fixed cylinder 203 through the mounting plate 204. At the same time, the mounting plate 204 pushes the sliding rod 205 and compresses the first spring 206, causing the first spring 206 to deform under force. At the same time, the sliding rod 205 pushes the compression plate 207 to compress the second spring 208, causing the second spring 208 to deform under force. The restoring elasticity of the second spring 208 and the first spring 206 can absorb and alleviate the impact force, thereby preventing the broken knife or workpiece from directly contacting the tempered glass 102 and causing the tempered glass 102 to break, effectively improving the safety of the protective door.

[0026] Example 2

[0027] Reference Figure 2 , 4 5 and 6 are the second embodiment of this utility model, which is based on the previous embodiment.

[0028] In this embodiment, the cleaning component 3 includes a fixed plate 301, a scraper 302, a protective cover 303, a servo motor 304, a drive wheel 305, a driven wheel 306, a threaded rod 307, a slider 308, and a groove 309. The fixed plate 301 is fixedly connected to the door panel 101, and the protective cover 303 is fixed to one end of the fixed plate 301.

[0029] The fixed plate 301 is fixed to the top of the fixed plate 301. The driving wheel 305 and the driven wheel 306 are both installed in the inner cavity of the protective cover 303. The threaded rod 307 and the slider 308 are both installed in the inner cavity of the fixed plate 301. The slide groove 309 is opened at the bottom of the fixed plate 301.

[0030] The slider 308 is sleeved on the surface of the threaded rod 307 and is threadedly connected to the surface of the threaded rod 307. The end of the slider 308 away from the threaded rod 307 passes through the slide groove 309 and is fixedly connected to the scraper 302, and is slidably connected to the inner cavity of the slide groove 309.

[0031] The output shaft of the servo motor 304 passes through the inner cavity of the protective cover 303 and is connected to the drive wheel 305. The drive wheel 305 and the driven wheel 306 are connected by a synchronous belt. One end of the threaded rod 307 passes through the inner cavity of the protective cover 303 and is connected to the driven wheel 306.

[0032] The other end of the threaded rod 307 is movably connected to the inner wall of the fixed plate 301 via a bearing, and the cleaning surface of the scraper 302 is in contact with the surface of the tempered glass 102.

[0033] like Figure 2 , 4 As shown in Figures 5 and 6, the protective cover 303 is used to protect the driving wheel 305 and the driven wheel 306. The output shaft of the servo motor 304 rotates, driving the driving wheel 305 to rotate. When the driving wheel 305 rotates, it drives the driven wheel 306 to rotate via a synchronous belt. When the driven wheel 306 rotates, it drives the threaded rod 307 to rotate in the inner cavity of the fixed plate 301. When the threaded rod 307 rotates, it drives the slider 308 to move along the surface of the threaded rod 307. When the slider 308 moves, it drives the scraper 302 to move along the inner cavity of the groove 309. When the scraper 302 moves, it can scrape off the cutting fluid on the surface of the tempered glass 102. The groove 309 can limit the movement trajectory of the slider 308. The cleaning surface of the scraper 302 can be made of silicone strip.

[0034] In use, the metal elastic mesh 202 and the protective frame 201 work together to intercept broken knives or workpieces. When impacted, the metal elastic mesh 202 causes the protective frame 201 to move closer to the door panel 101. As the protective frame 201 moves, it pushes the sliding rod 205 into the inner cavity of the fixed cylinder 203 via the mounting plate 204. Simultaneously, the mounting plate 204 compresses the first spring 206, causing it to deform. Simultaneously, the sliding rod 205 pushes the compression plate 207 into the inner cavity of the fixed cylinder 203, compressing the second spring 208 and causing it to deform. The restoring elasticity of the second spring 208 and the first spring 206 absorbs and mitigates the impact force. This prevents the broken blade or workpiece from directly contacting the tempered glass 102, thus preventing damage to the tempered glass 102 and effectively improving the safety of the protective door. The output shaft of the servo motor 304 rotates, driving the drive wheel 305 to rotate. When the drive wheel 305 rotates, it drives the driven wheel 306 to rotate via the synchronous belt. When the driven wheel 306 rotates, it drives the threaded rod 307 to rotate in the inner cavity of the fixed plate 301. When the threaded rod 307 rotates, it drives the slider 308 to move along the surface of the threaded rod 307. When the slider 308 moves, it drives the scraper 302 to move along the inner cavity of the groove 309. When the scraper 302 moves, it can scrape off the cutting fluid on the surface of the tempered glass 102.
