Wherein, 1, clamping part, 2, drill bit, 21, chip-removal hole, 22, drill plate, 23, screw thread, 24, necking drill bit, 25, expand Mouthful drill bit, 26, big drill, 3, boring bar tool.

Specific implementation mode

Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings.

Technical solution used by the utility model is：As shown in Figures 1 to 4, a kind of rubber drill bit comprising with drilling The clamping part 1 that tool 3 is connected and the drill bit 2 for drilling, the drill bit 2 are attached with clamping part 1 by screw thread 23, can Drill bit 2 is selected according to actual condition, the drill bit 2 is provided circumferentially about to have chip-removal hole 21,2 front end of the drill bit to be provided with brill Hole blade 22.

Boring bar tool 3 is connected with 1 one end of clamping part of the application, and 1 other end of clamping part passes through screw thread 23 and drill bit 2 It is connected, by the way that clamping part 1 and drill bit 2 are arranged to dismountable mode, clamping part 1 and drill bit 2 need to be only dismantled i.e. Can, boring bar tool 3 and clamping part 1 need not be detached, a clamping part 1 can be attached with multiple drill bits 2, be dropped significantly Low production cost；The rubber scraps generated in boring procedure can be passed through chip-removal hole by the chip-removal hole 21 provided circumferentially about of drill bit 2 Self-discharged, it is high in machining efficiency, and processing can be carried out continuously.

Preferable scheme is that the drill bit includes three kinds, respectively necking drill bit 23, flaring drill bit 24 and big drill 25；By the setting of these three drill bits, the demand in various model apertures during rubber processing is met.

Preferable scheme is that the diameter of 22 front end of drill plate in the necking drill bit 24 be less than drill plate 22 with The diameter of 24 junction of necking drill bit, the drill plate 22 and the diameter of 24 junction of necking drill bit are equal to 1 diameter of clamping part, The diameter of 22 front end of drill plate is more than the diameter of drill plate 22 and 24 junction of necking drill bit in the flaring drill bit 25, The diameter of 22 front end of drill plate is equal to the diameter with 24 junction of necking drill bit, the big hole drill in the flaring drill bit 25 First 26 diameter is more than the diameter of clamping part 1.

Necking drill bit 23 is suitable for rubber bore dia and drills less than the rubber of 1 diameter of clamping part, and flaring drill bit 25 is suitable The rubber for being more than 1 diameter of clamping part for rubber bore dia drills, and big drill 26 is suitable for rubber bore dia and is more than folder The rubber for holding 1 diameter of portion drills.

Preferable scheme is that the angle between the drill plate 22 and clamping part 1 is 10 ° -15 °, which is discharge The best angle of rubber scrap.

Preferable scheme is that the boring bar tool 3 is rotation lathe or power drill.

The operation principle of the utility model is, when processing, boring bar tool drives entire clamping part rotation, drill bit also to follow one Rotation is played, when the drill plate below drill bit touches rubber tyre, drill plate can drill on rubber rapidly, boring procedure The rubber scraps of middle generation can be high in machining efficiency by chip-removal hole Self-discharged by chip-removal hole, and can be carried out continuously processing, leads to It crosses and clamping part and drill bit is arranged to dismountable mode, drill bit can be selected according to actual condition, it only need to be by clamping part and brill Head is dismantled, and without detaching boring bar tool and clamping part, a clamping part can be carried out with multiple drill bits Connection, greatly reduces production cost.

It is the preferred embodiment of the utility model above, does not impose any limitation on the present invention, Every foundation the technical essence of the utility model any simple modification, equivalent change and modification made to the above embodiment, Belong in the range of utility model technical solution.
