Description

Technical Field

[0001] The utility model relates to the technical field of numerically controlled lathes, in particular to an automatic material receiving device for numerically controlled lathes. Background Art

[0002] A CNC lathe is a high-precision, high-efficiency automated machine tool equipped with a multi-station turret or a power turret. The machine tool has a wide range of processing capabilities and can process complex workpieces such as straight cylinders, oblique cylinders, arcs, and various threads, grooves, worms, etc. It has various compensation functions such as linear interpolation and circular interpolation, and has played a good economic role in the mass production of complex parts.

[0003] For example, the automatic material receiving device for a CNC lathe disclosed in Chinese utility model CN218984056U specifically provides an automatic material receiving device for a CNC lathe, including a material receiving body, a sliding member is provided on the right side of the material receiving body, the sliding member is composed of a sliding sleeve and a connecting plate, a material receiving trough is provided on one side of the connecting plate, a collecting drawer is provided on the side of the material receiving trough, and also includes a lifting component for driving the connecting plate to rise and fall inside the sliding sleeve; a vibration filter component for receiving the workpiece and filtering debris during workpiece processing; and a cleaning component for cleaning debris on the surface of the workpiece on the vibration filter component.

[0004] When the above device is in use, the electric cylinder is used to control the up and down movement of the material trough, so that the spring at the bottom of the filter screen vibrates to shake off the debris on the collected workpiece into the collection box. The various components cooperate to clean the processed workpiece and then transport the workpiece through the transmission component. However, in actual use, the electric cylinder provided in the above device directly controls the up and down movement of the material trough, and the filter screen in the material trough is separately provided with a spring to cooperate with the movement of the material trough. In this process, the filter screen needs the material trough to move to produce shaking, but the material trough will not shake continuously, and the filter screen is not directly subjected to force, so the vibration degree is relatively light, which affects the cleaning effect of the workpiece. In order to solve this problem, we propose an automatic material receiving device for CNC lathes. Utility Model Content

[0037] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0038] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0039] In this application, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0040] The existing device is provided with a lifting component, which is used to adjust the distance between the receiving trough and the workpiece to be processed, so that the receiving trough can receive workpieces of different sizes, prevent them from falling out of the receiving trough, and reduce damage.

[0041] In the related art, the electric cylinder installed in the existing device directly controls the up and down movement of the material trough, and the filter in the material trough is separately provided with a spring to cooperate with the movement of the material trough. In this process, the filter needs the movement of the material trough to produce shaking, but the material trough will not shake continuously, and the filter is not directly subjected to force, so the vibration degree is relatively light, which affects the cleaning effect of the workpiece.

[0042] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides an automatic material feeding device for a CNC lathe. When it is needed, only the motor 21 needs to work. The motor 21 controls the rotation of the shaft 22 through the steering gear 211. The steering gear 211 is an existing component with two meshing bevel gears inside, which can change the rotation direction of the motor 21. Therefore, the motor 21 can control the rotation of the shaft 22. The rotation of the shaft 22 causes the two eccentric rotating members 221 to rotate. The protruding part of the eccentric rotating member 221 controls the movement of the rod body 222. The rod body 222 can drive the connecting block 23. Synchronous lifting and lowering, the lifting and lowering movement of the connecting block 23 causes the cylinder 1 24 on its top to move synchronously, the cylinder 1 24 extends and retracts on the cylinder 2 241, and the fixed block 25 and the material trough 13 on the top of the cylinder 2 241 are continuously pushed out and shake. At the same time, the spring 251 set at the bottom of the fixed block 25 keeps the fixed block 25 lifted up. When the cylinder 1 24 is controlled by the connecting block 23 to be pulled downward and contact the top of the cylinder 2 241, the cylinder 2 241 and the fixed block 25 are pulled to compress the spring 251. Under the action of the spring force, the spring 251 can be reset. In this process, the components cooperate to make the material trough 13 vibrate.

[0043] The present application is described below with reference to specific embodiments and with reference to the accompanying drawings:

[0044] Combine Figure 1-Figure 5 , the embodiment of the present application provides an automatic material receiving device for a CNC lathe, including a lathe device 1; the lathe device 1 includes: a lathe body 11; a robotic arm 12 is arranged on the lathe body 11; a conveyor belt 14 is arranged on the lathe body 11; a material receiving device 2 is provided on the lathe device 1, and the material receiving device 2 includes: a motor 21 is arranged on the outer wall of the lathe body 11, the output end of the motor 21 passes through the lathe body 11 and is fixedly connected to the steering gear 211; a rotating shaft 22 is arranged on the steering gear 211, and two eccentric rotating parts 221 are provided on the rotating shaft 22, and the middle of the eccentric rotating part 221 A rod body 222 is rotatably provided; a connecting block 23 is rotatably provided on the top of the rod body 1 222 through a rotating member 223; a cylinder body 24 is provided on the top of the connecting block 23, and a cylinder body 241 is sleeved on the outside of the cylinder body 1 24; a through groove is provided inside the connecting block 23, a rod body 242 is provided inside the through groove, and a block 243 is provided at the bottom of the rod body 242; a fixed block 25 is provided on the top of the cylinder body 241, a spring 251 is provided at the bottom of the fixed block 25, the fixed block 25 is rotatably connected to the material trough 13, and a filter screen 253 is provided inside the material trough 13.

[0045] When a user uses a CNC lathe to process a workpiece, the user sets the usage time of each component through the PLC controller on the lathe body 11. According to the pre-set time, after the robot arm 12 releases the processed workpiece, the workpiece falls into the trough 13 under the action of gravity. At this time, the motor 121 is working, and the motor 121 controls the rotation of the shaft 122 through the steering gear 211. The steering gear 211 is an existing component with two meshing bevel gears inside, which can change the rotation direction of the motor 121. Therefore, the motor 1 21 can control the rotation of the rotating shaft 1 22, and the rotation of the rotating shaft 1 22 causes the two eccentric rotating members 221 to rotate. The protruding portion of the eccentric rotating member 221 controls the movement of the rod body 1 222, and the eccentric rotating member 221 and the rod body 1 222 are rotatably connected. Therefore, the rod body 1 222 will move up and down when the eccentric rotating member 221 rotates. The connecting block 23 is rotatably connected to the rod body 1 222, so the rod body 1 222 can drive the connecting block 23 to rise and fall synchronously. The rising and falling movement of the connecting block 23 causes the cylinder body 1 24 on its top to move. Synchronous movement, cylinder 1 24 is arranged inside cylinder 2 241 and is slidably connected to cylinder 2 241, so when the connecting block 23 and cylinder 1 24 move synchronously, cylinder 1 24 stretches and contracts on cylinder 2 241, and the connecting block 23 and cylinder 1 24, rod 242 and block 243 inside cylinder 2 241 restrict cylinder 1 24 from being separated from cylinder 2 241, so the fixed block 25 and the trough 13 at the top of cylinder 2 241 are constantly pushed out and shake, and at the same time the spring 22 arranged at the bottom of the fixed block 25 51 keeps the fixed block 25 lifted up. When the cylinder 1 24 is controlled by the connecting block 23 to be pulled downward and contacts the top of the cylinder 2 241, the cylinder 2 241 and the fixed block 25 are pulled to compress the spring 2 251. Under the action of the spring force, the spring 2 251 can be reset. In this process, the various components cooperate to make the trough 13 vibrate, and the filter screen 253 inside the trough 13 vibrates synchronously to clean the debris on the workpiece. After cleaning, the baffle 271 is opened and the workpiece can fall onto the conveyor belt 14 for transportation.

[0046] In some embodiments, the trough 13 is rotatably connected to the lathe body 11 via a third rotating member 252. The third rotating member 252 is also slidably connected to the lathe body 11. The trough 13 changes its tilt angle when vibrating, thereby changing its position on the lathe body 11. The provision of the third rotating member 252 improves the stability of the device.

[0047] In some embodiments, a baffle 271 is rotatably mounted on the trough 13, and a second motor 27 is mounted on the outer sidewall of the trough 13. The output end of the second motor 27 is fixedly connected to the baffle 271. The second motor 27 can be used to control the baffle 271 to flip and drop the workpiece onto the conveyor belt 14, thereby improving the automation of the device.

[0048] In some embodiments, a collection box 28 is provided on the trough 13. A pulley 281 is provided inside the trough 13, and the collection box 28 is slidably connected to the trough 13 via the pulley 281. The collection box 28 is provided at the bottom of the filter 253 to collect debris. Therefore, when the collection box 28 needs to be cleaned, the user can pull out the collection box 28 for cleaning. The structure is simple and easy to use.

[0049] In some embodiments, the collection box 28 and the trough 13 are magnetically connected via a magnetic block 282. The magnetic block 282 has a moderate fixing effect, and the magnetic connection can be released manually, which can ensure the fixing effect of the collection box 28 and the trough 13 during use.

[0050] In some embodiments, a handle is provided on the outer side wall of the collection box 28. The handle can provide a force point for the user and facilitate the user to pull the collection box 28.

[0051] In some embodiments, a fixing frame 26 is provided on the lathe body 11, and a turntable 261 is provided on the fixing frame 26. The turntable 261 is fixedly connected to the rotating shaft 1 22. The fixing frame 26 and the turntable 261 provide support for the rotating shaft 1 22, thereby improving the stability of the entire device.

[0052] In some embodiments, a spring 1 244 is disposed inside the cylinder 1 24, and the spring 1 244 is sleeved outside the rod 2 242. The spring 1 244 can assist the rod 2 242 in quickly returning to its original position when the rod 2 242 is pulled, thereby improving the stability of the entire device.
