Abstract
Description
Technical Field
[0001] This application relates to the technical field of machining, and in particular to an automatic feeding device for machining. Background Technology
[0002] Machining is a manufacturing process that uses mechanical equipment to cut, grind, drill, punch, forge, and perform other processing on workpieces to change their shape, size, and surface quality to meet design requirements. An automatic feeding device in machining is a piece of equipment that can automatically transport the workpiece to be ground to the grinding station. It can improve production efficiency, reduce labor costs, and ensure the accuracy and stability of feeding.
[0003] A search revealed Chinese Patent Publication No. CN 222041722 U, which discloses an automatic feeding device for machining. The device includes a feeding box with an energy-saving monitoring component at its bottom. This component monitors and controls the operation of a cleaning structure. Inside the feeding box is a vibration arrangement component that controls the overall material arrangement. This automatic feeding device, equipped with the energy-saving monitoring component, allows the support wheels to contact the conveyor belt surface. Upon contact, the pressure sensor maintains a constant pressure reading on a flat conveyor belt. When the surface becomes dirty or uneven, the monitor controls a lifting push rod to adjust its height. This, in turn, controls the cleaning rollers and scrapers to contact the conveyor belt surface, removing dirt and grime. The energy-saving monitoring component reduces energy consumption, thus saving costs.
[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: In existing machining processes, when grinding is being performed, workers come into contact with the workpiece, making them susceptible to scratches from burrs on the workpiece surface. This also increases labor costs, increases worker fatigue leading to errors, and causes material blockages, thus delaying machining time. Utility Model Content

[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0023] This application discloses an automatic feeding device for machining. For example... Figure 1As shown, the system includes a base plate 1. A support frame 21 is fixedly installed at one end of the upper surface of the base plate 1. A motor 18 is fixedly installed at the bottom of the inner wall of the support frame 21. A rotating shaft 23 is fixedly installed on the output shaft of one side of the motor 18. The connection between the rotating shaft 23 and the eccentric wheel 15 is located at one-third away from the center. Under the action of the rotating shaft 23, the eccentric wheel 15 can rotate up and down. The eccentric wheel 15 is fixedly sleeved at the end of the rotating shaft 23 away from the motor 18. An elliptical ring 3 is slidably installed on the outer circumference of the eccentric wheel 15. A limiting vertical rod 2 is slidably inserted into the middle of both ends of the elliptical ring 3. The bottom of the limiting vertical rod 2 is fixedly installed on the upper surface of the base plate 1. The limiting vertical rod 2 is located on both sides of the support frame 21. The elliptical ring 3 slides on the surface of the limiting vertical rod 2, thus restricting the movement trajectory of the elliptical ring 3.
[0024] Please see Figure 1 and Figure 2 A pad 4 is fixedly installed on the top of the elliptical ring 3. A sliding vertical plate 13 is fixedly installed in the middle of the upper surface of the pad 4. An external limiting plate 5 is slidably sleeved on the outside of the sliding vertical plate 13. A support plate 17 is fixedly installed at the bottom of the back of the external limiting plate 5. The bottom of the support plate 17 is rotatably sleeved on the outside of the middle of the rotating shaft 23. The support plate 17 ensures that the rotating shaft 23 and the eccentric wheel 15 can rotate normally and prevent displacement. A transverse plate 14 is fixedly installed in the middle of the back of the external limiting plate 5. The end of the transverse plate 14 away from the external limiting plate 5 is rotatably connected to the middle of the rotating push plate 16 through a rotating rod. The transverse plate 14 acts as a fulcrum for the rotating push plate 16 at one end. The elliptical groove in the middle of the external limiting plate 5 matches the shape of the sliding vertical plate 13. The matching elliptical groove ensures that the sliding vertical plate 13 can slide smoothly vertically. A support frame 21 is fixedly installed on the top of the back of the external limiting plate 5. The bottom of the support frame 21 is fixedly installed on the upper surface of the base plate 1.
[0025] Please refer to the previous reading. Figure 1 and Figure 2A bottom frame 22 is fixedly installed on the top of the sliding vertical plate 13. The groove on the upper surface of the bottom frame 22 is trapezoidal. The trapezoidal shape at the bottom of the slide plate 10 is symmetrically arranged with the trapezoidal groove at the top of the bottom frame 22. The groove is trapezoidal, which is narrower at the top and wider at the bottom, to prevent the slide plate 10 from deviating from the track during movement. The slide plate 10 is slidably installed on the inner wall of the trapezoidal groove in the middle of the bottom frame 22. A blocking plate 8 is fixedly installed at the end of the slide plate 10 away from the first inclined rod 12. A feeding groove 7 is slidably sleeved at the end of the blocking plate 8 away from the slide plate 10. A feeding port is provided in the middle of the blocking plate 8. The diameter of the feeding port is smaller than the inner wall diameter of the feeding groove 7. The length of the blocking plate 8 is greater than its maximum movement distance. Scrapers are provided on both sides of the contact position between the feeding groove 7 and the blocking plate 8. The blocking plate 8 slides under the action of the slide plate 10. The feed inlet coincides with the middle of the feed trough 7 during its reciprocating motion, allowing the material to fall. The scraper on one side of the feed trough 7 removes impurities adhering to the surface of the block plate 8. A top support plate 9 is fixedly installed on the top of one side of the feed trough 7, supporting one side of the feed trough 7. The bottom of the top support plate 9 is fixedly installed on both sides of the top of the bottom frame 22 via connecting rods. Uprights 11 are slidably inserted into both ends of one side of the top support plate 9 via sliding rods. The bottom of the uprights 11 is fixedly installed on the top of the support frame 21. A crossbar 6 is installed on the outside of the feed slide plate 10 at the bottom of the feed trough 7. The other end of the crossbar 6 is fixedly installed on one side of the external limiting plate 5. When the bottom frame 22 moves up and down, it drives the top support plate 9 to slide on the surface of the uprights 11, increasing the stability during up and down movement under the action of the uprights 11.
[0026] Please see Figure 1 One end of the skateboard 10 is rotatably mounted with a first inclined rod 12 via a rotating frame. The end of the first inclined rod 12 away from the skateboard 10 is rotatably mounted with a rotating push plate 16. The bottom of the rotating push plate 16 is rotatably mounted with a second inclined rod 19 via a rotating rod. The end of the second inclined rod 19 away from the rotating push plate 16 is rotatably mounted with a third inclined rod 20 via a rotating rod. The connection point between the third inclined rod 20 and the eccentric wheel 15 is located at the center of one side of the eccentric wheel 15. The length of the third inclined rod 20 is less than the length of the second inclined rod 19. The third inclined rod 20 is connected to the edge of the eccentric wheel 15. Under the action of the rotation of the eccentric wheel 15, one end of the third inclined rod 20 can swing up and down while making circular motion. The end of the third inclined rod 20 away from the second inclined rod 19 is rotatably mounted on one side of the eccentric wheel 15 via a rotating rod.
[0027] The implementation principle of the automatic feeding device for machining according to this application embodiment is as follows: During use, the workpiece to be fed is placed inside the feeding trough 7. The motor 18 is started, providing power to drive the eccentric wheel 15 to rotate via the rotating shaft 23. Since the rotating shaft 23 is connected to the eccentric wheel 15 at one-third of its length, the eccentric wheel 15, under the action of the rotating shaft 23, drives the elliptical ring 3 to move up and down. The elliptical ring 3 drives the sliding vertical plate 13 above to move up and down. The sliding vertical plate 13 drives the bottom frame 22 above and the feeding trough 7 on one side to vibrate, preventing blockage of the workpiece inside the feeding trough 7 and ensuring that the feeding trough 7 remains unobstructed. When the eccentric wheel 15 rotates, it drives the third... One end of the diagonal rod 20 rotates, and the other end of the third diagonal rod 20 drives the second diagonal rod 19 to swing back and forth. Under the action of the second diagonal rod 19, the bottom of the rotating push plate 16 swings around the rotating rod in the middle of one end of the horizontal plate 14. Under the action of the top of the rotating push plate 16, one end of the first diagonal rod 12 moves. The first diagonal rod 12 pulls the slide plate 10 to move left and right. The slide plate 10 drives the blocking plate 8 to reciprocate inside the feeding groove 7. The feeding port in the middle of the blocking plate 8 reciprocates and overlaps with the middle of the feeding groove 7, so that the workpiece falls through the feeding port. This reduces the manual feeding process, reduces the dependence on manual labor, thereby reducing labor costs. It also reduces errors caused by factors such as human fatigue.
[0028] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
