Description

Technical Field

[0001] The utility model belongs to the technical field of numerical control machining centers, and particularly relates to a guide rail protection device for a numerical control machining center. Background Art

[0002] The CNC machining center is mainly composed of mechanical equipment and CNC system, which is suitable for processing complex parts. It can perform a variety of processing operations such as milling, boring, drilling, tapping and cutting threads. It has the characteristics of high precision, high efficiency and high automation, and is widely used in manufacturing industry, aerospace industry, shipbuilding industry and other fields.

[0003] At present, the Chinese utility model with the publication number of CN218518243U discloses a lathe guide rail protection device, including a guide rail housing, wherein a protection mechanism is arranged inside the guide rail housing; the protection mechanism includes a motor protection cover, a motor, a motor shaft, a threaded rod, a first gear, a second gear, a crushing rod, a crushing tooth and a first bearing; the top of one side of the guide rail housing is bolted with a motor protection cover, the motor is bolted with a motor on one side of the motor protection cover, one side of the motor is connected to a motor shaft, the side of the motor shaft away from the motor is fixedly connected with a threaded rod, and the side of the threaded rod away from the motor shaft passes through the guide rail housing and the first gear. This application uses the threaded rod on the motor to not only drive the table to move, but also can drive the two crushing rods and crushing teeth to rotate through the gears during the movement of the table, actively crush the fallen thread, process the thread, avoid the thread affecting the guide rail, and save energy without the need for additional driving equipment.

[0004] When the existing CNC machining center processes the workpiece, the hair and debris dropped during the processing are very easy to fall into the moving guide rail of the CNC machining center's processing table. When a large amount of hair and debris accumulates inside the guide rail, it will block the guide rail, making it difficult for the CNC machining center's processing table to move. The hair and debris are also easy to cause wear to the inside of the guide rail, and the guide rail is prone to shaking when moving, affecting the processing stability. At the same time, when the CNC machining center's processing table moves to the ends of the guide rail, it will contact the guide rail. Since the CNC machining center's processing table moves faster, it will collide with the guide rail, causing the CNC machining center's processing table to be unstable, affecting the processing accuracy. Utility Model Content

[0005] The utility model aims to provide a guide rail protection device for a CNC machining center, which has the advantages of protecting the guide rails of the CNC machining center, reducing the vibration caused by the collision with the guide rails and preventing the processed hair debris from falling into the guide rails.

[0006] The above-mentioned technical purpose of the utility model is achieved through the following technical scheme: a guide rail protection device of a CNC machining center, comprising a guide rail, a motor is installed on one side of the guide rail, a screw rotatably connected to the guide rail is installed on the output end of the motor, the surface of the screw is threadedly sleeved with a threaded sleeve, the top of the threaded sleeve is fixedly connected to a slide frame slidably connected to the guide rail, both ends of the slide frame are fixedly connected to sliders, both sides of the guide rail are rotatably connected with a take-up wheel, the surface of the take-up wheel is fixedly wrapped with a protective belt fixedly connected to the slider, both ends of the slider pass through the guide rail and are fixedly connected to a toothed plate slidably connected to the guide rail, both ends of the take-up wheel pass through the guide rail and are fixedly connected to a toothed belt pulley, and the surface of the toothed belt pulley is meshingly sleeved with a toothed belt meshing with the toothed plate.

[0007] By adopting the above technical scheme, the toothed plate is meshed with the inner ring surface of the toothed belt, so that the toothed belt drives the winding wheels at both ends of the guide rail to rotate in the same direction, and the protective belt covers the position where the top of the guide rail and the slide frame are not in contact, thereby realizing the protection of the guide rail of the CNC machining center and preventing the hair and debris from being processed from falling into the inside of the guide rail, thereby improving the stability of the movement of the machining table of the CNC machining center inside the guide rail; after the buffer plate contacts and collides with the slide frame, the telescopic rod and the spring are continuously contracted and rebounded to buffer the collision force, and at the same time, the slide frame will not vibrate under the thread engagement friction of the screw and the threaded sleeve, thereby reducing the jitter caused by the collision with the guide rail and improving the machining accuracy of the machining table of the CNC machining center.

[0008] The utility model is further configured as follows: telescopic rods are fixedly installed on both sides of the guide rail, the surface of the telescopic rods is sleeved with springs fixedly installed with the guide rails, and one end of the telescopic rods close to the slide is fixedly connected with a buffer plate used in conjunction with the slide.

[0009] By adopting the above technical solution, after the buffer plate contacts and collides with the slide frame, the telescopic rod and the spring are continuously contracted and rebounded to buffer the collision force, thereby reducing the jitter caused by the collision with the guide rail and improving the machining accuracy of the machining table of the CNC machining center.

[0010] The utility model is further configured as follows: through grooves used in conjunction with the protective belt are provided on both sides of the top of the guide rail.

[0011] By adopting the above technical solution, it is convenient to clean up the hair debris dropped from the top of the protective belt through the through groove.

[0012] The utility model is further configured as follows: a heat dissipation net used in conjunction with the motor is installed at one end of the guide rail outside close to the motor.

[0013] By adopting the above technical solution, the motor can be ventilated and cooled to improve working stability.

[0014] The utility model is further configured as follows: both sides of the bottom of the guide rail are fixedly connected with mounting bolts.

[0015] The above technical solution makes it easy to install the guide rail on the platform of the CNC machining center.

[0016] The utility model is further configured as follows: a buffer pad used in conjunction with the slide frame is bonded to one side of the buffer plate close to the slide frame.

[0017] By adopting the above technical solution, the buffering effect on the sliding platform is improved and the collision sound is reduced.

[0018] The utility model is further configured as follows: the surface of the protective belt is coated with organic silicon high temperature resistant paint.

[0019] The above technical solution is adopted to prevent the high-temperature hair debris caused by grinding and cutting from burning the protective belt, thereby increasing the service life of the protective belt.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. The toothed plate meshes with the inner ring surface of the toothed belt, so that the toothed belt drives the winding wheels at both ends of the guide rail to rotate in the same direction, so that the protective belt covers the position where the top of the guide rail and the slide frame do not contact, thereby protecting the guide rail of the CNC machining center and preventing the processed hair debris from falling into the inside of the guide rail, thereby improving the stability of the CNC machining center's machining table moving inside the guide rail;

[0022] 2. After the buffer plate contacts and collides with the slide, the telescopic rod and spring are used to continuously contract and rebound, thereby buffering the collision force. At the same time, the slide will not vibrate under the thread engagement friction of the screw and the threaded sleeve, thereby reducing the jitter caused by the collision with the guide rail and improving the processing accuracy of the CNC machining center processing table.
