Description

Technical Field

[0001] This utility model belongs to the field of CNC machine tool technology, and in particular relates to a CNC milling machine with a protective mechanism. Background Technology

[0002] This CNC milling machine with protective mechanisms includes a machine body, a material discharge pipe, a CNC control center, and a sliding protective door on the side of the machine body. Inside, there is a machine tool, a cross slide, a worktable, and a spindle. It is also equipped with a cleaning mechanism and a water spraying mechanism. The cleaning mechanism is driven by a motor-driven threaded rod, which in turn drives a threaded sleeve, a cleaning plate, and a bottom cleaning brush assembly to clean the worktable. The water spraying mechanism uses a gear and rack transmission to cause a pressure plate to squeeze the water tank, and water is sprayed through a telescopic water pipe from a nozzle with a circumferential array of water holes. The whole machine achieves automated cleaning, improves machining accuracy and equipment life, and provides strong protection.

[0003] A CNC milling machine with a protective device, according to a formula (publication number: CN112296741A), includes: a CNC milling machine, a base fixed below the CNC milling machine, an inner chamber inside the base, threaded sleeves symmetrically fixed to the bottom inner wall of the inner chamber via bearings, the other end of a rotating shaft passing through the right inner wall of the inner chamber and fixed to a rocker arm, threaded rods threadedly connected to each threaded sleeve, the bottom ends of each threaded rod fixed to a movable plate, and a protective cover passing through the top inner wall of the inner chamber fixed to the upper end of the movable plate. This CNC milling machine with a protective device only requires manual rotation of the rocker arm to rotate the threaded rods, pushing the protective cover located in the base to rise, fully protecting the working area. This prevents metal chips generated during high-speed milling of metal materials by the CNC milling machine from flying into the working area near the milling machine, causing a deterioration of the working environment and potentially injuring workers.

[0004] Although the above-mentioned application achieves the protection of CNC milling machine through the cooperation of components such as the rotating shaft and the threaded sleeve, it also has the disadvantage of poor cleaning effect of the machine bed, resulting in low machining accuracy. Therefore, we propose a CNC milling machine with a protective mechanism. Utility Model Content

[0005] The purpose of this invention is to provide a CNC milling machine with a protective mechanism. Through the design of components such as a cleaning mechanism and a water spraying mechanism, the problem of poor cleaning effect of the machine bed in the prior art is solved.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a CNC milling machine with a protective mechanism, including a machine body, a discharge pipe fixedly connected to the side of the machine body, a CNC control center fixedly connected to the side of the machine body, a protective door slidably connected to the side of the machine body, a machine tool fixedly connected to the inner side of the machine body, a cross slide slidably connected to the top of the machine tool, a worktable slidably connected to the top of the cross slide, a spindle slidably connected to the side of the machine tool, and a cleaning mechanism provided inside the machine body;

[0008] The cleaning mechanism includes a motor, the side of which is bolted to the side of the slide plate. The side of the motor is bolted with screws. A threaded rod is fixedly connected to the end of the motor output shaft. A threaded sleeve is threaded to the circumferential surface of the threaded rod. A telescopic adjustment seat is fixedly connected to the circumferential surface of the threaded sleeve. A cleaning plate is snapped onto the side of the telescopic adjustment seat. A cleaning brush assembly is fixedly connected to the bottom of the cleaning plate.

[0009] Furthermore, the side of the body is provided with a sliding groove, and the number of sliding grooves is set to a certain extent and arranged in a linear array on the side of the body, which provides guidance and support for the sliding of the protective door, ensuring that the protective door can be opened and closed stably and smoothly along the sliding groove, thereby improving the operational stability of the protective mechanism.

[0010] Furthermore, the number of screws is set to several and is symmetrical about each other along the vertical central axis of the motor, which can evenly transmit the vibration and torque generated by the motor during operation and prevent the motor from loosening or deviating due to single-point force. The number of threaded rods and threaded sleeves is set to two and is symmetrical about each other along the vertical central axis of the slide plate, which makes the movement of the cleaning mechanism on the slide plate more stable, avoids jamming or deflection caused by uneven force on one side, and ensures that the cleaning brush group accurately covers the entire area of ​​the workbench.

[0011] Furthermore, the number of cleaning brush sets is set to several, and they are arranged in a linear array at the bottom of the cleaning plate. The top of the workbench is located on the displacement trajectory of the cleaning brush sets, avoiding blind spots in cleaning and achieving all-round cleaning of the top of the workbench.

[0012] Furthermore, the machine body is equipped with a water spraying mechanism, which includes a gear. The side of the gear is fixedly connected to the end of the threaded rod away from the motor. A rack is slidably connected to the side of the transverse slide plate. The gear and the rack mesh with each other. A connecting plate is fixedly connected to the side of the rack. A pressing rod is fixedly connected to the top of the connecting plate. A pressing plate is fixedly connected to one end of the pressing rod. A water tank is fixedly connected to the side of the transverse slide plate. The circumferential surface of the pressing plate is slidably connected to the inner side of the water tank. A telescopic water pipe is fixedly connected to the circumferential surface of the water tank. A nozzle is fixedly connected to the side of the telescopic water pipe.

[0013] Furthermore, there are two gears and racks, which are symmetrical to each other along the vertical central axis of the connecting plate. The side of the telescopic water pipe is located on the displacement trajectory of the extrusion plate, ensuring that the extrusion rod and the extrusion plate move smoothly along the central axis of the water tank, avoiding sealing failure or structural wear caused by off-center loading.

[0014] Furthermore, the nozzle has water holes on its side, and the number of water holes is set to several and arranged in a circumferential array on the side of the nozzle to form a ring-shaped water curtain, which can simultaneously cover multiple areas of the workbench, cleaning brush assembly and surrounding components, avoiding the cleaning blind spots that exist in traditional unidirectional water spraying.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model utilizes the coordinated operation of components such as threaded rods, threaded sleeves, and cleaning brush sets within the cleaning mechanism. A motor drives the threaded rod to rotate, causing the threaded sleeve and telescopic adjustment seat to move. This allows the cleaning brush sets at the bottom of the cleaning plate to clean the worktable surface, efficiently removing residual debris and preventing impurities from affecting processing accuracy. The numerous and arrayed cleaning brush sets, combined with the worktable's displacement trajectory design, ensure comprehensive cleaning coverage, achieving automated cleaning, reducing manual operation, and improving equipment maintenance efficiency.

[0017] 2. This utility model utilizes the interplay of gears, racks, and extrusion plates within the water spray mechanism. The rotation of the threaded rod drives the gears, which in turn mesh with the rack to move the connecting plate and extrusion rod. This causes the extrusion plate to squeeze water from the water tank, which is then sprayed out from the nozzle through a telescopic water pipe. The nozzle features numerous water holes arranged in a circumferential array, effectively rinsing away residual debris and stains on the workbench, enhancing cleaning efficiency. The symmetrical arrangement of the gears and rack improves operational stability. No additional power source is required, saving energy. Automated operation reduces manual labor, improving the cleanliness of the processing environment and extending equipment lifespan.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5 This utility model is a CNC milling machine with a protective mechanism, including a machine body 1, a discharge pipe 2 fixedly connected to the side of the machine body 1, a CNC control center 3 fixedly connected to the side of the machine body 1, a protective door 4 slidably connected to the side of the machine body 1, a machine tool 5 fixedly connected to the inner side of the machine body 1, a cross slide 6 slidably connected to the top of the machine tool 5, a worktable 7 slidably connected to the top of the cross slide 6, a spindle 8 slidably connected to the side of the machine tool 5, and a cleaning mechanism 9 provided inside the machine body 1;

[0029] The cleaning mechanism 9 includes a motor 91, the side of which is bolted to the side of the slide plate 6. The side of the motor 91 is bolted with screws 92. The end of the output shaft of the motor 91 is fixedly connected to a threaded rod 93. The circumferential surface of the threaded rod 93 is threadedly connected to a threaded sleeve 94. The circumferential surface of the threaded sleeve 94 is fixedly connected to a telescopic adjustment seat 95. The side of the telescopic adjustment seat 95 is snapped with a cleaning plate 96. The bottom of the cleaning plate 96 is fixedly connected to a cleaning brush assembly 97.

[0030] As shown in the figure, the side of the body 1 is provided with a sliding groove. The number of sliding grooves is set in a linear array on the side of the body 1 to provide guidance and support for the sliding of the protective door 4, ensuring that the protective door 4 can open and close stably and smoothly along the sliding groove, thereby improving the operational stability of the protective mechanism.

[0031] As shown in the figure, there are several screws 92, which are symmetrically arranged along the vertical central axis of the motor 91. This ensures that the vibration and torque generated by the motor 91 during operation are transmitted evenly, preventing the motor 91 from loosening or shifting due to single-point force. There are two threaded rods 93 and two threaded sleeves 94, which are symmetrically arranged along the vertical central axis of the slide plate 6. This makes the movement of the cleaning mechanism 9 on the slide plate 6 more stable, avoids jamming or tilting caused by uneven force on one side, and ensures that the cleaning brush assembly 97 accurately covers the entire area of ​​the workbench 7.

[0032] As shown in the figure, there are several cleaning brush sets 97, which are arranged in a linear array at the bottom of the cleaning plate 96. The top of the workbench 7 is located on the displacement trajectory of the cleaning brush sets 97, avoiding blind spots and achieving all-round cleaning of the top of the workbench 7.

[0033] As shown in the figure, the machine body 1 is equipped with a water spraying mechanism 10. The water spraying mechanism 10 includes a gear 101. The side of the gear 101 is fixedly connected to the end of the threaded rod 93 away from the motor 91. The side of the transverse slide plate 6 is slidably connected to a rack 102. The gear 101 and the rack 102 mesh with each other. The side of the rack 102 is fixedly connected to a connecting plate 103. The top of the connecting plate 103 is fixedly connected to a pressing rod 104. One end of the pressing rod 104 is fixedly connected to a pressing plate 105. The side of the transverse slide plate 6 is fixedly connected to a water tank 106. The circumferential surface of the pressing plate 105 is slidably connected to the inner side of the water tank 106. The circumferential surface of the water tank 106 is fixedly connected to a telescopic water pipe 107. The side of the telescopic water pipe 107 is fixedly connected to a nozzle 108.

[0034] As shown in the figure, there are two gears 101 and racks 102, which are symmetrical to each other along the vertical central axis of the connecting plate 103. The side of the telescopic water pipe 107 is located on the displacement trajectory of the extrusion plate 105, ensuring that the extrusion rod 104 and the extrusion plate 105 move smoothly along the central axis of the water tank 106, avoiding sealing failure or structural wear caused by uneven load.

[0035] As shown in the figure, the nozzle 108 has water holes on its side. The number of water holes is set to several and they are arranged in a circumferential array on the side of the nozzle 108 to form a ring-shaped water curtain, which can simultaneously cover multiple areas of the workbench 7, cleaning brush group 97 and surrounding components, avoiding the cleaning blind spots that exist in traditional unidirectional water spraying.

[0036] A specific application of this embodiment is as follows: The operator starts the motor 91, whose output shaft drives two symmetrical threaded rods 93 to rotate. This causes the threaded sleeve 94 to move linearly along the axial direction of the threaded rods 93. The threaded sleeve 94 drives the telescopic adjustment seat 95 and the engaged cleaning plate 96 to move synchronously. Several cleaning brush groups 97 at the bottom of the cleaning plate 96 move with it. Since the top of the worktable 7 is on the movement trajectory of the cleaning brush groups 97, the cleaning brush groups 97 clean the surface of the worktable 7 during movement, removing debris and dust generated during processing. The symmetrical design of the double threaded rods 93 and the threaded sleeve 94 ensures the smooth movement of the cleaning plate 96, while the linear array of cleaning brush groups 97 ensures that the entire worktable 7 is thoroughly cleaned, achieving automated cleaning and maintenance of the processing area.

[0037] When the threaded rod 93 rotates, it drives the end gear 101 to rotate, and the rack 102 meshing with the gear 101 moves accordingly. The rack 102 drives the connecting plate 103 and the extrusion rod 104 to move, causing the extrusion plate 105 to slide inside the water tank 106. Because the displacement trajectory of the extrusion plate 105 covers the side of the telescopic water pipe 107, the extrusion plate 105 extrudes the cleaning fluid inside the water tank 106, which flows through the telescopic water pipe 107 and is delivered to the nozzle 108. The water holes in the circumferential array on the side of the nozzle 108 spray water out, which works in conjunction with the cleaning mechanism 9 to rinse the workbench 7.
