Description

Technical Field

[0001] The utility model relates to the technical field of nut feeding devices, in particular to a stainless steel nut feeding device. Background Art

[0002] The parts used in mechanical equipment are large and small, with different shapes. During the processing of these mechanical parts, the shapes of the blanks are also very different. During processing, these blanks need to be fed onto the machine tool.

[0003] For example, the authorization announcement number "CN205916798U" is titled "a nut feeding device." The nut feeding device is designed by combining a storage box, a receiving box, a rotating shaft, a base, a striking rod, a feeding rail, a fixed bin, a pyramidal surface, and a feeding hole. The middle part of the storage box is made into a pyramidal surface, so the nuts slide smoothly along the pyramidal surface inside the storage box with little resistance. The feeding hole is machined in the center of the storage box, so the nuts fall smoothly from the feeding hole. However, when the storage box is hit by the striking rod, the nuts will be thrown out and fall to the outside of the bottom box. At the same time, the nuts will fall on the inner wall of the bottom box, producing a loud impact sound. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figure 1-5A stainless steel nut feeding device includes a storage bin 1. A connecting pipe 2 is provided on the surface of the storage bin 1. The connecting pipe 2 prevents the nuts from falling out of the transition bin 3, ensuring the safe and stable operation of the device. A transition bin 3 is provided at the lower end of the connecting pipe 2. A fixed bin 4 is provided in front of the transition bin 3. A feeding rail 5 is connected between the transition bin 3 and the fixed bin 4. A cut-off device is provided on one side surface of the feeding rail 5 near the transition bin 3. A plurality of legs 6 are provided on the lower surface of the transition bin 3 and the feeding rail 5. The plurality of legs 6 serve to support the transition bin 3 and the feeding rail 5. A feed hole 7 is provided on the lower inner wall of the storage bin 1. The feed hole 7 is a circular hole. The radial dimension of the feed hole 7 is equal to the diameter of the hexagonal circumscribed circle of the nut, ensuring that the nut can fall smoothly from the feed hole 7. The feed hole 7 connects the storage bin 1 and the transition bin 3. A bin cover 8 is provided on the upper end of the storage bin 1. The bin cover 8 serves to isolate noise. A handle 9 is provided on the top of the silo cover 8. A fixing bracket 10 is provided on the underside of the inner wall of the connecting pipe 2. A buffer device is provided on the top surface of the fixing bracket 10. The outer surfaces of the storage silo 1, connecting pipe 2, transition bin 3, and feed rail 5 are all provided with a sound insulation layer 11. This layer 11 significantly reduces noise and absorbs the sound of the nut impact. Multiple first cylinders 12 are evenly distributed on the top surface of the transition bin 3. Each of these first cylinders 12 has a first telescopic rod 13 on its top surface, and a collision seat 14 is provided on the top end of each of these first telescopic rods 13.

[0021] The buffer device includes a buffer spring 15 . The buffer spring 15 is arranged on the upper surface of the fixing frame 10 . A buffer cap 16 is provided at the upper end of the buffer spring 15 .

[0022] A protective edge 17 is provided in an annular shape on the lower surface of the buffer cap 16. The protective edge 17 prevents the nut from hitting the buffer spring 15.

[0023] A slide bar 18 is provided on the lower surface of the buffer cap 16. The slide bar 18 is arranged inside the buffer spring 15. The lower end of the slide bar 18 slides through the fixing frame 10. The slide bar 18 can make the buffer cap 16 fall more steadily.

[0024] The cut-off device includes a second cylinder 19 , a second telescopic rod 20 is provided on one side surface of the second cylinder 19 , a supporting plate 21 is provided at one end of the second telescopic rod 20 , a stop plate 22 is provided at one side end of the supporting plate 21 , and the stop plate 22 slides through the feeding rail 5 .

[0025] A positioning groove 23 is provided on the inner wall of one side of the feeding rail 5, and one end of the retaining plate 22 extends into the positioning groove 23. The positioning groove 23 can make the retaining plate 22 and the feeding rail 5 resist more tightly.

[0026] Working principle: First, the nut is placed in the storage bin 1, and the first cylinder 12 is started to extend the first telescopic rod 13, and the impact seat 14 hits the lower surface of the storage bin 1. The nut is vibrated and falls into the connecting pipe 2 through the discharge hole 7, and then hits the buffer cap 16. The buffer spring 15 is compressed by the buffer cap 16 to buffer the nut, and then falls into the transition bin 3, and slides into the fixed bin 4 through the feeding rail 5. If the nut needs to be cut off, start the second cylinder 19 to shorten the second telescopic rod 20, and then probe into the positioning groove 23 through the baffle plate 22 to complete the cutting operation, which can prevent the nut from sliding down.
