Description
Technical Field
[0001] The utility model relates to the technical field of numerical control processing equipment, in particular to a numerical control processing machine tool with a dustproof structure. Background Art
[0002] CNC machine tool is the abbreviation of digitally controlled machine tool. It is an automated machine tool equipped with a program control system. The control system can logically process programs specified by control codes or other symbolic instructions, decode them, express them in coded numbers, and input them into the CNC device through information carriers. After calculation and processing, the CNC device sends various control signals to control the movement of the machine tool and automatically process parts according to the shape and size required by the drawing.
[0003] In order to reduce the amount of dust from the outside falling on the CNC machine, a dustproof door is usually slidably installed on the CNC machine, and then a track is opened on the CNC machine. The dustproof door slides in the track. The dustproof door is opened when in use and closed when shutting down the machine, which can effectively block the outside dust.
[0004] Although the above-mentioned existing CNC machining center with a dustproof door can achieve dustproof effect, impurities generated by the workpiece are easy to fall into the track during actual use, which hinders the dustproof door from sliding in the track and causes motion interference. Moreover, since the internal space of the track is narrow, it is inconvenient for personnel to clean the impurities inside.
[0005] Therefore, we designed a CNC machining center with a dustproof structure to solve the above problems. Utility Model Content
[0006] The purpose of the utility model is to provide a CNC machine tool with a dustproof structure to solve the problems raised in the above background technology.
[0007] In order to solve the above technical problems, the utility model provides a CNC machining center with a dustproof structure, comprising a CNC machine, a slide rail provided on the CNC machine, a dustproof door slidably inserted into the slide rail, and a sliding member installed at the bottom of the dustproof door, including:
[0008] A fixing groove is vertically provided at the bottom of the dustproof door;
[0009] The magnetic metal block is slidably inserted into the fixing slot along the direction in which the fixing slot is set, and a connecting strip is fixedly installed at the bottom;
[0010] The spring has two ends fixedly connected to the top wall of the fixing groove and the top of the magnetic metal block respectively;
[0011] A U-shaped frame is fixedly mounted on the bottom end of the connecting bar, and a guide rod is fixedly mounted on the U-shaped frame in the transverse direction;
[0012] The scraper is movably mounted on the guide rod and abuts against the bottom wall of the slide rail to remove impurities splashed into the slide rail;
[0013] The slag discharge port is opened on one side of the CNC machine and is connected to the inside of the slide rail.
[0014] Furthermore, an electromagnet is fixedly mounted on the top wall of the fixing groove, and the electromagnet is magnetically connected to the magnetic metal block.
[0015] Furthermore, a limiting rod is inserted into the magnetic metal block, one end of the limiting rod is fixedly connected to the inner top wall of the fixing groove, and the other end of the limiting rod is in a suspended state.
[0016] Furthermore, there are two limit rods, and the two limit rods are symmetrically inserted into the magnetic metal block.
[0017] Furthermore, a rotating shaft is rotatably provided on the U-shaped frame, a gear is fixedly sleeved on the other end of the rotating shaft, a rack is fixedly installed on the top of the scraper, the gear is meshed with the rack, a driving member is fixedly installed on one side of the U-shaped frame, and the driving shaft of the driving member is transmission-connected to one end of the rotating shaft.
[0018] Furthermore, the driving member includes a motor, and a driving shaft of the motor is transmission-connected to one end of the rotating shaft.
[0019] Furthermore, the sliding member includes a ball, the ball is rotatably mounted on the bottom of the dustproof door, and the ball is rollingly connected in the slide rail.
[0020] Furthermore, a placement groove is provided at the bottom of the dustproof door, and the ball is rotatably installed in the placement groove.
[0021] Compared with the prior art, the beneficial effects of the present invention are:
[0022] 1. When there are impurities splashed during workpiece processing in the slide rail, the thrust of the spring can push the U-shaped frame and the scraper downward against the bottom wall of the slide rail. As the dustproof door slides, the scraper can remove the impurities that fall into the slide rail and finally discharge them through the slag discharge port, thus achieving the effect of automatically cleaning the impurities in the slide rail and ensuring smooth sliding of the slide rail.
[0023] 2. By energizing the electromagnet, the electromagnet can generate magnetic force to attract the magnetic metal blocks to move upward and offset each other, so that the scraper can be suspended in the air. The scraper can be properly stored when there is no need to clean the slide rail, avoiding the scraper from sliding repeatedly with the dustproof door for a long time, which is beneficial to alleviate the wear of the scraper and extend its service life.
[0024] 3. By turning on the motor, the rotating shaft can drive the gear to rotate alternately clockwise and counterclockwise, and can drive the rack and the scraper to reciprocate along the direction set by the guide rod, which can cut the stubborn agglomerates formed by the mixture of impurities and mechanical lubricating oil, thereby improving the effect of cleaning impurities.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0032] See also Figure 1-5 The utility model provides a technical solution: a CNC machine tool with a dustproof structure, comprising a CNC machine 1, a slide rail 3 provided on the CNC machine 1, a dustproof door 2 slidably inserted into the slide rail 3, and a sliding member installed at the bottom of the dustproof door 2, including:
[0033] A fixing groove 4 is vertically provided at the bottom of the dustproof door 2;
[0034] The magnetic metal block 5 is slidably inserted into the fixing slot 4 along the direction in which the fixing slot 4 is set, and a connecting strip 7 is fixedly installed at the bottom;
[0035] The spring 6 has two ends fixedly connected to the top wall of the fixing groove 4 and the top of the magnetic metal block 5 respectively;
[0036] A U-shaped frame 8 is fixedly mounted on the bottom end of the connecting bar 7, and a guide rod 9 is fixedly mounted on the U-shaped frame 8 in the transverse direction;
[0037] The scraper 10 is movably mounted on the guide rod 9 and abuts against the inner bottom wall of the slide rail 3 to remove impurities splashed into the slide rail 3;
[0038] The slag discharge port 18 is provided on one side of the CNC machine 1 and is communicated with the interior of the slide rail 3 .
[0039] During specific implementation, by pulling the dustproof door 2, the dustproof door 2 can be made to slide in the slide rail 3, and the processing area on the CNC machine 1 can be blocked to achieve a dust-proof effect. When there are impurities splashed during workpiece processing in the slide rail 3, the thrust of the spring 6 can push the U-shaped frame 8 and the scraper 10 downward against the bottom wall of the slide rail 3. As the dustproof door 2 slides, the scraper 10 can remove the impurities that fall into the slide rail 3 and finally discharge them through the slag discharge port 18, thereby achieving the effect of automatically cleaning the impurities in the slide rail 3, ensuring that the slide rail 3 can slide smoothly.
[0040] See Figure 1-5 As shown, an electromagnet 11 is fixedly mounted on the top wall of the fixing groove 4 and is magnetically connected to the magnetic metal block 5. By energizing the electromagnet 11, it generates a magnetic force that attracts the magnetic metal block 5 upward and counteracts it, thereby suspending the scraper 10. This allows for convenient storage without having to clean the slide rail 3, and prevents the scraper 10 from being damaged by repeated friction with the dustproof door 2 over a long period of time.
[0041] See Figure 1-5 A limiting rod 12 is inserted into the magnetic metal block 5. One end of the limiting rod 12 is fixedly connected to the inner top wall of the fixing groove 4, and the other end of the limiting rod 12 is suspended in the air. This can limit the sliding direction of the magnetic metal block 5, preventing the magnetic metal block 5 from slipping out of the fixing groove 4, and improving the stability of the magnetic metal block 5.
[0042] See Figure 1-5 , the number of the limiting rods 12 is two, and the two limiting rods 12 are symmetrically inserted in the magnetic metal block 5. The symmetrical arrangement of the two limiting rods 12 can balance the magnetic metal block 5 on both sides when sliding, avoiding the problem of tilting.
[0043] See Figure 1-5A rotating shaft 13 is rotatably provided on the U-shaped frame 8, and a gear 14 is fixedly sleeved on the other end of the rotating shaft 13. A rack 15 is fixedly installed on the top of the scraper 10, and the gear 14 is meshed with the rack 15. A driving member is fixedly installed on one side of the U-shaped frame 8, and the driving shaft of the driving member is transmission-connected to one end of the rotating shaft 13. The driving member includes a motor 16, and the driving shaft of the motor 16 is transmission-connected to one end of the rotating shaft 13.
[0044] During specific implementation, when impurities are mixed with the lubricating oil used for the machine and fall into the slide rail 3, stubborn lumps are easily formed, and it is not easy to remove the stubborn lumps by relying on the inertia of the dustproof door 2 to drive the scraper 10. In this case, the motor 16 can be turned on to make the rotating shaft 13 drive the gear 14 to rotate alternately clockwise and counterclockwise, so that the rack 15 and the scraper 10 can be driven to reciprocate along the direction set by the guide rod 9, and the stubborn lumps can be cut, thereby improving the cleaning effect of impurities.
[0045] The sliding member in this embodiment is a ball bearing 17, which is rotatably mounted on the bottom of the dustproof door 2 and rolls within the slide rail 3. The bottom of the dustproof door 2 defines a receiving groove within which the ball bearing 17 is rotatably mounted. By rotatably mounting the ball bearing 17 on the bottom of the dustproof door 2, the ball bearing 17 rolls within the slide rail 3 during movement of the dustproof door 2, converting the sliding friction of the dustproof door 2 into rolling friction, thereby reducing frictional force and, consequently, frictional losses.
[0046] In addition, regarding the power supply problem of the electromagnet 11, the electromagnet 11 can be connected to the main body of the CNC machine 1 through a line, the electromagnet 11 can be powered, and then a switch can be installed on the CNC machine 1 to control the switch and operating status of the electromagnet 11. Since the power supply problem and the switch of the electromagnet 11 belong to the existing technology, this manual will not elaborate on them.
[0047] It should be noted that the CNC machine 1 is equipped with a program control system, which logically processes control codes or symbolic instructions, and sends control signals through decoding and calculation processing to automatically process parts according to the requirements of the drawings. Since the CNC machine 1 belongs to the existing technology, it will not be elaborated in this manual.
[0048] Working principle: When in use, by pulling the dustproof door 2, the dustproof door 2 can slide in the slide rail 3, which can block the processing area on the CNC machine 1 and achieve the effect of dust prevention. In addition, by rotatably installing the ball 17 at the bottom of the dustproof door 2, the ball 17 can be made to roll in the slide rail 3 during the movement of the dustproof door 2, which can change the sliding friction of the dustproof door 2 into rolling friction, reducing friction, thereby reducing friction loss;
[0049] When impurities splashed during workpiece processing exist in the slide rail 3, the thrust of the spring 6 can push the U-shaped frame 8 and the scraper 10 downward against the bottom wall of the slide rail 3. As the dustproof door 2 slides, the scraper 10 can scrape off the impurities that fall into the slide rail 3 and finally discharge them through the slag discharge port 18, thereby achieving the effect of automatically cleaning the impurities in the slide rail 3 and ensuring the smooth sliding of the slide rail 3.
[0050] It should be noted that by energizing the electromagnet 11, the electromagnet 11 can generate a magnetic force to attract the magnetic metal block 5 to move upward and counteract it, so that the scraper 10 can be suspended in the air, which can be conveniently stored properly without cleaning the slide rail 3, thereby avoiding the problem of the scraper 10 being damaged by the friction caused by long-term repeated movement of the dustproof door 2;
[0051] In addition, when impurities are mixed with the lubricating oil used for the machine and fall into the slide rail 3, stubborn lumps are easily formed. At this time, it is not easy to remove the stubborn lumps by relying on the inertia of the dustproof door 2 to drive the scraper 10. The motor 16 can be turned on to make the rotating shaft 13 drive the gear 14 to rotate alternately clockwise and counterclockwise, so that the rack 15 and the scraper 10 can be driven to reciprocate along the direction set by the guide rod 9, and the stubborn lumps can be cut, thereby improving the effect of cleaning impurities.
