Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples.

The utility model discloses an automatic drill bit feeding device, as shown in figure 1, which comprises an operation table top 1 and a tool table top 2; the operation table board 1 is provided with a charging barrel 3, and a drill bit tool 4 is arranged on a tool table board 2 right below the charging barrel 3; the lower part of the charging barrel 3 is provided with an upper cylinder 5 and a lower cylinder 6. The section of the inner hole of the charging cylinder 3 is a profiling hole 8 corresponding to the section of the large head end of the drill bit 7. The side surface of the charging barrel 3 is provided with an observation hole 9; the observation hole 9 is formed in the shape of a long hole provided along the longitudinal direction of the charging barrel 3. The upper cylinder 5 and the lower cylinder 6 are connected to the lower portion of the charging barrel 3 via a cylinder frame 10.

As shown in fig. 2, the drill bit tool 4 includes a base 11, the base 11 is a circular tube structure, a flange 12 is disposed at the top end of the circular tube, a set of guide posts 13 are disposed at the edge of the flange 12 and are uniformly distributed along the circumference, and a buffer disc spring 14 is sleeved on the guide posts 13.

As shown in fig. 3, the ends of the telescopic rods 15 of the upper cylinder 5 and the lower cylinder 6 are provided with notches 16.

The working process and principle of the present invention are further explained below:

the working object of the present invention is a bit as shown in fig. 4, which is seen from fig. 4. The shape of the drill bit is a cylinder structure with a big end and a small end, therefore, the utility model discloses according to the shape of drill bit, the shape of the inner hole cross section of the charging barrel 3 is the profiling hole 8 corresponding to the shape of the big end cross section of the drill bit 7. The circumferential preliminary positioning of the drill bit 7 can be achieved during the insertion of the drill bit into the cartridge 3. The length of the charging barrel 3 can be adjusted automatically according to the requirement. Meanwhile, the alternating operation of the upper air cylinder 5 and the lower air cylinder 6 can realize that the drill bits 7 are placed in the seat body 11 one by one. The distance between the upper air cylinder 5 and the lower air cylinder 6 is different by the height of the drill bit 7, and when the upper air cylinder 5 and the lower air cylinder 6 are at the initial positions, the telescopic rods 15 of the two air cylinders are in an extending state. When a drill bit 7 needs to be placed, the telescopic rod 15 of the lower air cylinder 6 retracts into the air cylinder, the telescopic rod 15 of the upper air cylinder 5 blocks the upper drill bit 7, and the drill bit 7 falls from the bottom of the charging barrel 3. Then the telescopic rod 15 of the lower cylinder 6 extends again, the telescopic rod 15 of the upper cylinder 5 retracts, the drill bit 7 falling from the upper side is blocked by the telescopic rod 15 of the lower cylinder 6, and then the telescopic rod 15 of the upper cylinder 5 extends again and is inserted above the drill bit 7 at the lowest side. Ready for the next feed. After the drill bit 7 falls into the base body 11, the drill bit and the base body 11 are sent into an alloy column press-fitting station together by the tooling table board 2.

The utility model discloses an automatic feed of bore bit has improved work efficiency, also provides favourable guarantee for bore bit automated production afterwards.
