[0002] A machining center is a highly efficient automated machine tool composed of mechanical equipment and a numerical control system, suitable for machining complex parts. Currently, CNC machining centers are among the most productive and widely used CNC machine tools in the world.

[0003] During the machining process of the machining center, the debris generated will fly out and hit the protective door, causing damage to the inner wall of the protective door. At the same time, it will generate a lot of noise. The noise will pass through the gap between the protective door and the machine body, causing noise pollution to the outside world. Utility Model Content

[0004] The purpose of the utility model is to provide a machining center protection device in view of the defects and shortcomings of the prior art.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a machining center protection device, including a machining center body, and its innovation lies in: a shell is arranged inside the machining center body, and multiple groups of roller assemblies are arranged inside the shell, and are arranged in an arc structure, and each group of roller assemblies consists of a pair of rollers, and an arc-shaped guide groove is arranged between the roller assemblies, and an arc-shaped protective cover is arranged in the guide groove and between the rollers. The protective cover moves along the guide groove under the action of the roller assembly, and an opening for the protective cover to enter and exit is provided on the shell. A motor is also arranged in the shell, and a driving wheel is arranged on the output shaft of the motor. At the same time, the rollers are connected by pulleys and belts for transmission, and a driven wheel is provided on one of the rollers, and is connected to the driving wheel through a belt.

[0006] Furthermore, a magnet sheet with an arc-shaped structure is embedded in the inner side of the protective cover.

[0007] Furthermore, a rubber scraper is provided at the opening, and the rubber scraper is pressed against the inner side of the protective cover.

[0008] Furthermore, a material collection box is provided below the opening.

[0009] After adopting the above structure, the beneficial effects of the utility model are:

[0010] The utility model provides a movable protective cover, which can be moved between the protective door and the machine body during processing in the machining center. On the one hand, it can prevent debris from bouncing out and hitting the protective door to avoid damage to the protective door, and at the same time it can reflect noise, thereby achieving a noise reduction effect. At the same time, a magnet sheet can absorb the debris, and when the protective cover retracts, the debris is scraped off by the rubber scraper and then collected by the aggregate box, avoiding manual cleaning and effectively reducing the labor intensity of the staff.

[0014] 1 machining center body, 2 shell, 3 roller assembly, 4 guide groove, 5 protective cover, 6 opening, 7 motor, 8 driving wheel, 9 pulley, 10 belt, 11 magnet sheet, 12 rubber scraper, 13 collection box. DETAILED DESCRIPTION

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0017] See Figure 1-2A machining center protection device includes a machining center body 1, a shell 2 is arranged inside the machining center body 1, and multiple groups of roller assemblies 3 are arranged inside the shell 2, and are arranged in an arc structure, and each group of roller assemblies consists of a pair of rollers, and an arc-shaped guide groove 4 is arranged between the roller assemblies 3, and an arc-shaped protective cover 5 is arranged in the guide groove 4 and between the rollers. The protective cover 5 moves along the guide groove 4 under the action of the roller assembly 3, and an opening 6 for the protective cover to enter and exit is opened on the shell 2. A motor 7 is also arranged in the shell 2, and a driving wheel 8 is arranged on the output shaft of the motor 7. At the same time, the rollers are connected by pulleys 9 and belts 10, and a driven wheel is provided on one of the rollers, and is connected to the driving wheel 8 through a belt. Specifically, during use, the motor 7 drives the roller assembly 3 to rotate through the driving wheel 8 and the belt, and the roller assemblies 3 rotate through the pulley and the belt 10, thereby applying force to the protective cover 5, so that it moves from the shell 2 to between the protective door and the machine body. On the one hand, it can prevent debris from bouncing out and hitting the protective door, avoiding damage to the protective door. At the same time, the arc-shaped structure of the protective cover can effectively reflect noise, thereby achieving a noise reduction effect; the roller surface adopts convex points to increase friction, so that it can effectively apply force to the protective cover 5, which is beneficial to the discharge and retraction of the protective cover 5. At the same time, the protective cover is made of lightweight material, which is further beneficial to the operation of the protective cover 5; the guide groove 4 is a U-shaped structure for supporting the protective cover 5, and a roller is arranged at the bottom of the guide groove 4, thereby reducing the friction with the protective cover 5, which is beneficial to the operation of the protective cover.

[0018] In this embodiment, a magnet sheet 11 having an arc-shaped structure is embedded in the inner side of the protective cover 5. The magnet sheet 11 is used to absorb the flying debris, so as to collect the debris in a centralized manner, thereby facilitating centralized cleaning of the debris in the later stage.

[0019] In this embodiment, a rubber scraper 12 is provided at the opening 7, and the rubber scraper 12 abuts against the inner side of the protective cover 5. When the protective cover 5 retracts, the rubber scraper 12 is used to scrape off the debris adsorbed by the magnet sheet 11, thereby ensuring the normal use of the magnet sheet 11.

[0020] In this embodiment, a collection box 13 is provided below the opening 7. The collection box 13 is used to collect the debris scraped off by the rubber scraper 12, thereby avoiding manual cleaning and effectively reducing the labor intensity of the staff.

[0021] The above description is only used to illustrate the technical solution of the present invention and is not intended to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
