Description
Technical field
The utility model belongs to machining equipment field, is related to a kind of drill bit device of the big aperture of synchronous processing.
Background technology
Traditional drill bit divides straight shank drill and taper shank drill, and the less drill bit of outside diameter is designed to straight shank drill at present, outside diameter compared with
Small drill bit drill thrust is little, and clamping frictionally by collet drives bit operation；The larger drill bit of outside diameter is designed to taper shank
Bore, the big drill bit drill thrust of outside diameter is big, with collet can not clamping operation, by Morse's taper self-locking clamp, to meet bit bore
Work.
It is first with straight shank drill that macropore hole machined is complete such as according to traditional processing method when product has large and small hole at the same time,
Taper shank drill machining small, secondary clamping are used again, it is difficult to ensure the position degree in two groups of holes, and low production efficiency.Therefore it is badly in need of design one
Kind staight shank, taper shank drill converter device, taper shank drill is converted into by straight shank drill, while processes large and small hole, improves product quality and production
Efficiency.
Utility model content
The purpose of this utility model is to provide a kind of drill bit device of the big aperture of synchronous processing, and being mainly used for need to be at the same time with straight
Handle bores and the product of taper shank drill.
The utility model is realized in this way：
A kind of drill bit device of the big aperture of synchronous processing, including multi-shaft device, some sets in multi-shaft device shaft bore
Head conversion equipment, according to the size of boring aperture be installed on big ting model different straight shank drill and taper shank on drill bit conversion equipment
Bore, the drill bit conversion equipment includes the Mohs No.1 taper shank with internal taper hole and the straight tube with clear opening, Mohs No.1 taper shank
Head is connected with shaft, and Mohs No.1 taper shank turns the reducing hole of taper hole with straight tube formation clear opening, is equipped with the stack shell of straight tube
Two threaded holes, are equipped with screw in two threaded holes, the center line of two threaded holes is vertical with the axis of straight tube, each straight shank drill
Drill bit and each taper shank drill drill bit at grade.
The Mohs No.1 taper shank is structure as a whole with straight tube.
The Mohs No.1 taper shank internal taper hole and the clear opening of straight tube are coaxial.
Drill bit conversion equipment in the utility model is versatile, you can to meet straight shank drill, and can meet taper shank drill
Installation, can also realize the large and small hole of synchronous processing, product quality can be effectively improved, greatly improve production efficiency.

Embodiment
The utility model by the following examples the utility model can be made into-step description, however, this practicality
New scope is not limited to following embodiments.
Embodiment 1：Referring to Fig. 1 --- a kind of drill bit device of the big aperture of synchronous processing of Fig. 3, including multi-shaft device 1, installation
Some set drill bit conversion equipments 3 in 1 shaft 2 of multi-shaft device, be installed on drill bit conversion equipment 3 according to the size of boring aperture
Big ting model different straight shank drill and taper shank drill, the drill bit conversion equipment 3 include 31 He of Mohs No.1 taper shank with internal taper hole
Straight tube 32 with clear opening, the head of Mohs No.1 taper shank 31 are connected with shaft 2, and Mohs No.1 taper shank 31 is formed directly with straight tube 32
Through hole turns the reducing hole of taper hole, and two threaded holes are equipped with the stack shell of straight tube 32, is equipped with screw 33 in two threaded holes, and two
The center line of a threaded hole is vertical with the axis of straight tube 32, and the drill bit of the drill bit of each straight shank drill and each taper shank drill is in same plane
On.The Mohs No.1 taper shank 31 is structure as a whole with straight tube 32.31 internal taper hole of Mohs No.1 taper shank is straight with straight tube 32
Through hole is coaxial.The internal taper hole of the Mohs No.1 taper shank 31 is with the concentricity 0.02mm of Mohs No.1 taper shank, installing staight shank
Screw 33 is first unclamped when boring 34, screw 33 is tightened after the insertion of 34 bar portion of straight shank drill, first unclamps screw when taper shank drill is installed
33, the internal taper hole of the bar portion insertion Mohs No.1 taper shank 31 of taper shank drill can be realized that self-locking clamps, you can to meet staight shank
Brill is clamped by frictional force, while can meet that the independent self-locking of taper shank drill clamps again.
By taking rear axle shaft as an example, for semiaxis ring flange as shown in figure 3, there is two groups of holes, first group is that six holes are uniformly distributed hole, point
It is 139.7mm to spend circle, and aperture is 13.6 ± 0.1mm, and second group of hole is that holes is uniformly distributed hole, reference circle 139.7mm, hole
Footpath is 5.1 ± 0.1mm, and 5.1mm drill bit staight shanks outside diameter is 5.1 ± 0.03 mm, is highly 115mm.13.6mm taper shank drill is high
Spend for 180mm.
Converter body diameter of bore is 5.1mm+0.055mm+0.04mm, is matched somebody with somebody with 5.1mm drill bit staight shanks for gap
Close, bore depth 36mm, during processing as needed at the same time using cover more above-mentioned drill bit conversion equipment 3 install respectively straight shank drill and
Taper shank drill, drill bit conversion equipment 3 is installed on multi-shaft device 1, the drill bit of the drill bit of each straight shank drill and each taper shank drill is same
In plane, so as to ensure the position degree in two groups of holes, the utility model drill bit conversion equipment is versatile, you can to meet staight shank
Bore, and can meet the installation of taper shank drill, can also realize the large and small hole of synchronous processing, product quality can be effectively improved, greatly
Improve production efficiency.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
