Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, specifically to a CNC machine tool with a protective mechanism. Background Technology

[0002] A CNC machine tool is an automated machine tool equipped with a program control system. This control system can logically process programs with control codes or other symbolic instructions, decode them, represent them with coded numbers, input them to the CNC device through an information carrier, and after calculation and processing, the CNC device sends out various control signals to control the machine tool's movements. It automatically processes parts according to the shape and dimensions required by the drawings. The machining of parts on a CNC machine tool mainly depends on the machining program. Unlike ordinary machine tools, it does not require the manufacture or replacement of many molds and fixtures, nor does it require frequent readjustment of the machine tool. Therefore, CNC machine tools are suitable for situations where the parts being machined frequently change, that is, suitable for the production of single-piece or small-batch products and the development of new products, thereby shortening the production preparation cycle and saving a significant amount of process equipment costs.

[0003] Chinese patent CN220993775U discloses a novel protective mechanism for CNC machine tools. By activating two sets of motors via a control panel, the motor outputs drive a threaded rod to rotate along the inner side of a threaded hole. Simultaneously, the bottom of the threaded rod rotates along a bearing seat, causing two sets of support seats to move the protective door downwards. During this downward movement, the auxiliary slider further moves downwards along the inside of a groove until the support seats contact the limit switch. This allows the protective door to cover the machine tool housing, preventing debris from flying during machining of internal parts. The mechanism eliminates the need for manual opening and closing of the protective door, saving time and effort and improving the protective effect.

[0004] In the aforementioned patent, during CNC machine tool processing, a protective door is used to block the splashing of chips and cutting fluid. However, the side of the protective door is often equipped with an observation window, and chips and cutting fluid easily adhere to the surface of the observation window, which affects the operator's vision and makes it difficult to intuitively understand the working status of the machine tool. Therefore, this does not meet the existing needs, and a CNC machine tool with a protective mechanism is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a CNC machine tool with a protective mechanism. When the protective plate is closed, as the CNC machine tool body begins its cutting operation, workpiece chips and cutting fluid gradually adhere to the surface of the observation window. At this time, the operator moves the movable plate under the observation window using an electric telescopic rod, and the nozzle washes the surface of the observation window. Then, the electric telescopic rod drives the movable plate to move back and forth, allowing the water-absorbing cleaning sponge to scrape off the adhering substances on the surface of the observation window, preventing the adhering substances on the observation window from obstructing the operator's view, improving processing efficiency, and solving the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a CNC machine tool with a protective mechanism, comprising a CNC machine tool body, a protective plate, and a closed groove. The protective plate is located on one side of the CNC machine tool body, and an observation window is provided inside the protective plate. A movable plate is provided between the protective plate and the CNC machine tool body. A machining center is provided inside the CNC machine tool body, and a three-jaw chuck is provided inside the machining center. An upper guide groove, a first driven gear, and a first slide rail are provided on the top of the CNC machine tool body. A lower guide groove, a second driven gear, and a second slide rail are provided on the side of the CNC machine tool body. A nozzle is provided inside the movable plate, and a touch switch is provided inside the closed groove.

The upper limit plate is located inside the upper guide groove, and the lower limit plate is located inside the lower guide groove.

[0008] Preferably, a first rack is provided on the upper side of the protective plate, and a second rack is provided on the side of the protective plate. The first rack meshes with a first driven gear, and the second rack meshes with a second driven gear.

[0009] Preferably, the CNC machine tool body is equipped with a motor inside, a first transmission shaft is provided above the motor, the upper end of the first transmission shaft is connected to a first driven gear, the lower end of the first transmission shaft is connected to the motor, and a first driving gear is provided outside the first transmission shaft.

[0010] Preferably, the CNC machine tool body is provided with a second transmission shaft inside, one end of the second transmission shaft is connected to a second driven gear, and the other end of the second transmission shaft is provided with a second driving gear, which meshes with a first driving gear.

[0011] Preferably, the spray nozzle has its spray end facing the side of the observation window, a cleaning sponge is provided on one side of the movable plate, and a first slider and a second slider are provided on the other side of the movable plate.

[0012] Preferably, the first slider is mounted on the first slide rail, the second slider is mounted on the second slide rail, and a first fixed plate and a second fixed plate are provided below the movable plate.

[0013] Preferably, both the first fixing plate and the second fixing plate are mounted on the CNC machine tool body, and an electric telescopic rod, a water tank and a water pump are provided between the first fixing plate and the second fixing plate.

The two ends of the electric telescopic rod are respectively fixed to the first fixed plate and the second fixed plate. One end of the electric telescopic rod is provided with a connecting plate, which is connected to the movable plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In this utility model, after one end of the protective plate is moved into the closed groove by a motor, the protective plate is in a closed state. As the CNC machine tool body begins its cutting operation, the workpiece chips and cutting fluid gradually adhere to the surface of the observation window. At this time, the operator moves the movable plate to the bottom of the observation window using an electric telescopic rod, and the nozzle washes the surface of the observation window. Then, the electric telescopic rod moves the movable plate back and forth, allowing the water-absorbing cleaning sponge to scrape off the adhering substances on the surface of the observation window, preventing the adhering substances on the observation window from obstructing the operator's view, reducing the frequency of wiping the observation window, and improving processing efficiency.

[0017] 2. This utility model provides a touch switch inside the enclosed slot. When a person starts the motor, the motor drives the first and second transmission shafts to rotate, which in turn drives the first and second driven gears to rotate, causing the protective plate to move. When one end of the protective plate enters the enclosed slot and triggers the touch switch, the motor shuts off, thus ensuring that the protective plate is completely closed and preventing personnel from accidentally entering the interior of the machining center, which could lead to personal safety accidents.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] To address the issue of workpiece debris and cutting fluid easily adhering to the observation window surface, obstructing the operator's view and making it difficult to intuitively understand the machine tool's operating status, please refer to... Figure 1-5 This utility model provides an embodiment of a CNC machine tool with a protective mechanism, including a CNC machine tool body 1, a protective plate 2, and a closed groove 202. The protective plate 2 is located on one side of the CNC machine tool body 1, and an observation window 201 is provided inside the protective plate 2. A movable plate 3 is provided between the protective plate 2 and the CNC machine tool body 1. A machining center is provided inside the CNC machine tool body 1, and a three-jaw chuck 101 is provided inside the machining center. An upper guide groove 102, a first driven gear 104, and a first slide rail 106 are provided on the top of the CNC machine tool body 1. A lower guide groove 103, a second driven gear 105, and a second slide rail 107 are provided on the side of the CNC machine tool body 1. A nozzle 301 is provided inside the movable plate 3, and a touch switch is provided inside the closed groove 202.

[0026] The upper end of the protective plate 2 is provided with an upper limit plate 203, and the lower end of the protective plate 2 is provided with a lower limit plate 204. The upper limit plate 203 is located inside the upper guide groove 102, and the lower limit plate 204 is located inside the lower guide groove 103. A first rack 205 is provided on the upper side of the protective plate 2, and a second rack 206 is provided on the side of the protective plate 2. The first rack 205 meshes with the first driven gear 104, and the second rack 206 meshes with the second driven gear 105. A motor 4 is provided inside the CNC machine tool body 1. A first drive shaft 401 is provided at the top, the upper end of the first drive shaft 401 is connected to the first driven gear 104, the lower end of the first drive shaft 401 is connected to the motor 4, a first driving gear 403 is provided on the outside of the first drive shaft 401, and a second drive shaft 402 is provided inside the CNC machine tool body 1, one end of the second drive shaft 402 is connected to the second driven gear 105, and the other end of the second drive shaft 402 is provided with a second driving gear 404, which meshes with the first driving gear 403.

[0027] After the motor 4 drives one end of the protective plate 2 to move into the closed groove 202, the protective plate 2 is in the closed state. As the CNC machine tool body 1 begins its cutting operation, the workpiece chips and cutting fluid gradually adhere to the surface of the observation window 201. At this time, the operator moves the movable plate 3 under the observation window 201 using the electric telescopic rod 304. The nozzle 301 then rinses the surface of the observation window 201. Afterward, the electric telescopic rod 304 drives the movable plate 3 to move back and forth, causing the cleaning sponge 302, which has absorbed water and expanded, to scrape off the adhering substances on the surface of the observation window 201. This prevents the adhering substances on the observation window 201 from obstructing the operator's view, reduces the frequency of wiping the observation window 201, and further improves processing efficiency.

[0028] The spray nozzle 301 faces the side of the observation window 201. A cleaning sponge 302 is provided on one side of the movable plate 3, and a first slider 309 and a second slider 310 are provided on the other side of the movable plate 3. The first slider 309 is mounted on the first slide rail 106, and the second slider 310 is mounted on the second slide rail 107. A first fixed plate 303 and a second fixed plate 307 are provided below the movable plate 3. Both the first fixed plate 303 and the second fixed plate 307 are mounted on the CNC machine tool body 1. An electric telescopic rod 304, a water tank 305, and a water pump 308 are provided between the first fixed plate 303 and the second fixed plate 307. The water pump 308 is connected to the water tank 305 through a water pipe, and the water pump 308 is connected to the nozzle 301 through a water pipe. The two ends of the electric telescopic rod 304 are fixed to the first fixed plate 303 and the second fixed plate 307 respectively. A connecting plate 306 is provided at one end of the electric telescopic rod 304, and the connecting plate 306 is connected to the movable plate 3.

[0029] When the operator starts the motor 4, the motor 4 sequentially drives the first drive shaft 401, the first drive gear 403, and the first driven gear 104 to rotate. The first drive gear 403 then sequentially drives the second drive gear 404, the second drive shaft 402, and the second driven gear 105 to rotate, causing the protective plate 2 to move. When one end of the protective plate 2 enters the interior of the closed groove 202 and triggers the touch switch, the motor 4 shuts off, thus ensuring that the protective plate 2 is completely closed. This prevents personnel from accidentally entering the interior of the machining center and causing personal safety accidents, and further improves the standardization of personnel using the CNC machine tool body 1 for machining.

[0030] Working principle: After the motor 4 drives one end of the protective plate 2 to move into the closed groove 202, the protective plate 2 is in the closed state. As the CNC machine tool body 1 begins its cutting operation, the workpiece chips and cutting fluid gradually adhere to the surface of the observation window 201. At this time, the operator moves the movable plate 3 under the observation window 201 by using the electric telescopic rod 304. The nozzle 301 washes the surface of the observation window 201. Then, the electric telescopic rod 304 drives the movable plate 3 to move back and forth, so that the cleaning sponge 302, after absorbing water and expanding, scrapes off the adhering substances on the surface of the observation window 201, preventing the adhering substances on the observation window 201 from obstructing the operator's view, reducing the frequency of wiping the observation window 201, and improving processing efficiency.
