[0002] In existing workpiece cutting equipment, such as lathes, sawing machines, laser cutting machines, plasma cutting machines, etc., an automatic feeding mechanism is usually required to achieve continuous cutting of workpieces. The current feeding mechanism is mainly composed of a series of combinations such as a driver, a threaded rod, a feed block and its auxiliary devices. The driver drives the threaded rod to rotate, and then the linear motion of the feed block is achieved through the interaction between the threaded rod and the feed block. However, most of the feeding mechanisms do not have a self-cleaning structure. After the feed mechanism works for a long time, metal debris is easily accumulated in the spiral groove of the threaded rod, which may cause the movement of the feed block to be blocked, and it is easy to cause damage to the thread or scratches inside the feed block.

Detailed implementation mode
[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.
[0020] The present invention provides a technical solution: As Figure 1 and Figure 4 shown, in this embodiment, an automatic feeding mechanism for workpiece cutting includes a template 1. A threaded rod 2 is rotatably connected inside the template 1. A driver 3 is provided on one side of the template 1. A slide block 4 is threadedly connected to the threaded rod 2. A sleeve 7 is fixedly connected to the side surface of the slide block 4. A cleaning structure 6 is provided inside the slide block 4. The cleaning structure 6 is rotatably connected inside the sleeve 7. A lubricating structure 8 is fixedly connected to one side of the slide block 4. The lubricating structure 8 is connected to the sleeve 7. A groove 9 is opened inside the sleeve 7. The cleaning structure 6 includes a first worm 601, a second worm 602, a motor 604 and a cleaning brush sleeve 605. An auxiliary ring 607 is fixedly connected to one side of the cleaning brush sleeve 605. A worm gear 606 is fixedly connected to one side of the auxiliary ring 607. The first worm 601 is externally connected with an anti-slip belt 603.
[0021] As Figure 1 and Figure 3 shown, the output shaft of the driver 3 is connected to the threaded rod 2. The driver 3 drives the threaded rod 2 to rotate forward and backward. A mounting block 5 is fixedly connected above the slide block 4. The first worm 601 is rotatably connected inside the slide block 4. The second worm 602 is rotatably connected inside the slide block 4. The motor 604 is fixedly connected outside the slide block 4. The output shaft of the motor 604 is connected to the first worm 601. The first worm 601 is connected to the second worm 602 through the anti-slip belt 603. The second worm 602 meshes with the worm gear 606. The cleaning brush sleeve 605 is rotatably connected inside the sleeve 7.
[0022] By setting the anti-slip belt 603 and the auxiliary ring 607, the worm 601 is driven by the motor 604 to rotate. Since the worm 601 is connected to the worm 602 through the anti-slip belt 603, the worm 601 and the worm 602 will rotate synchronously. And the worm gear 606 meshes with the worm 602, and the cleaning brush sleeve 605 will rotate in the slider 4 through the auxiliary ring 607 and the worm gear 606. When the anti-slip belt 603 drives the worm 601 and the worm 602 to operate, the generated noise and vibration can be reduced, which helps to improve the comfort of the working environment. And when the worm gear 606 receives a turning force, it will drive the auxiliary ring 607 to rotate in the slider 4, so that the auxiliary ring 607 plays a certain supporting role in the rotation of the cleaning brush sleeve 605, preventing the cleaning brush sleeve 605 from falling off during rotation.
[0023] As Figure 4 shown, the lubrication structure 8 includes a liquid storage tank 801, the liquid storage tank 801 is fixedly connected to the other side of the slider 4, a controller 802 is fixedly connected to the front of the liquid storage tank 801, a connecting pipe 803 is connected to the outside of the liquid storage tank 801, the connecting pipe 803 is clamped with the sleeve 7, and a water pump is provided in the liquid storage tank 801.
[0024] By setting the lubrication structure 8, the water pump inside the liquid storage tank 801 is controlled by the controller 802 to operate, and the water pump will transport the lubricating oil in the liquid storage tank 801 through the connecting pipe 803. After the lubricating oil is transported, it will be evenly sprayed on the surface of the threaded rod 2. After cleaning the surface of the threaded rod 2, its surface can be lubricated, reducing the temperature of the friction between the surface of the slider 4 and the threaded rod 2, and ensuring the flexibility of the feeding mechanism.
[0025] The present utility model provides an automatic feeding mechanism for workpiece cutting, and the specific working principle is as follows:
[0026] When the feeding mechanism is operating, it will drive the threaded rod 2 to rotate in the sleeve plate 1 through the driver 3, and then realize the linear motion of the feeding block through the interaction between the threaded rod 2 and the slider 4. During the movement of the slider 4, the worm 601 is driven by the motor 604 to rotate. Since the worm 601 is connected to the worm 602 through the anti-slip belt 603, the worm 601 and the worm 602 will rotate synchronously. And the worm gear 606 meshes with the worm 602, and the cleaning brush sleeve 605 will rotate in the slider 4 through the auxiliary ring 607 and the worm gear 606, and the cleaning brush sleeve 605 will clean the surface of the threaded rod 2, and the debris after cleaning will fall through the groove 9. When the feeding mechanism operates for a long time, the water pump inside the liquid storage tank 801 is controlled by the controller 802 to operate, and the water pump will transport the lubricating oil in the liquid storage tank 801 through the connecting pipe 803. After the lubricating oil is transported, it will be evenly sprayed on the surface of the threaded rod 2.
[0027] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
