When via bottoms need chamfering, then must by product upset, again clamping be processed, processing efficiency is extremely low, and 2 times plus
Work, also in the presence of certain error, causes the crudy of product bad.
The content of the invention
The utility model purpose is to provide a kind of via bottoms facing attachment, by using the structure, without rotating product,
Realize directly carries out chamfering to the bottom of product through hole, prevents secondary operation error, improves processing efficiency and crudy.
To reach above-mentioned purpose, the technical solution adopted in the utility model is：A kind of via bottoms facing attachment, including turn
Axle, the rotating shaft top is provided with connecting portion, and the rotating shaft bottom end face is provided with a facing attachment, and the facing attachment includes connecting
Extension bar and the rose reamer of connecting rod bottom is arranged at, the blade of the rose reamer is set towards the rotating shaft bottom end face, described
Connecting rod is installed vertically on the rotating shaft bottom end face, and the axial line of the connecting rod is between the axial line of the rotating shaft
Distance is the 1/4 of the shaft diameter, and the rose reamer is arranged at the bottom outside of the connecting rod, and the rose reamer away from
The axial line of the rotating shaft is set.
In above-mentioned technical proposal, the connecting portion is provided with a positioning through hole, and the positioning through hole is perpendicular to the rotating shaft
Axial line set.
In above-mentioned technical proposal, the rose reamer is set perpendicular to the connecting rod, the medial surface of the rose reamer and institute
The bottom for stating connecting rod is connected, and the lateral surface of the rose reamer is set away from the axial line of the rotating shaft.
In above-mentioned technical proposal, the lateral surface of the rose reamer be arranged in parallel with the connecting rod, the knife of the rose reamer
Sword is arranged at the top of rose reamer, and the outer end of the blade is connected with the lateral surface of the rose reamer, the blade it is inner with
The connecting rod is connected, and the angle between the blade and the connecting rod in 135 °~150 °.
In above-mentioned technical proposal, the diameter of the connecting rod is less than the 1/4 of the shaft diameter.
Because above-mentioned technical proposal is used, the utility model has following advantages compared with prior art：
1. facing attachment is set by rotating shaft bottom in the utility model, facing attachment includes connecting rod and blade upward
Rose reamer, wherein the axial line of connecting rod to the distance between the axial line of the rotating shaft is the 1/4 of the shaft diameter, is led to
Cross and the axial line of rotating shaft overlaps with the axial line of product through hole, rotating shaft, you can drive connecting rod and rose reamer to rotate, profit
Chamfering is carried out to the edge of through hole with blade, the chamfering of via bottoms is realized, via bottoms are capable of achieving without overturning product
Chamfering, it is convenient and swift, without secondary positioning product, secondary operation error is prevented, improve through hole chamfer quality.
Brief description of the drawings
Fig. 1 is the structural representation in the utility model embodiment one.
Wherein：1st, rotating shaft；2nd, connecting portion；3rd, connecting rod；4th, rose reamer；5th, blade；6th, positioning through hole；7th, lateral surface.
Specific embodiment
Below in conjunction with the accompanying drawings and embodiment is further described to the utility model：
Embodiment one：It is shown in Figure 1, a kind of via bottoms facing attachment, including rotating shaft 1, the top of the rotating shaft 1 is provided with
Connecting portion 2, the bottom end face of the rotating shaft 1 is provided with a facing attachment, and the facing attachment includes connecting rod 3 and is arranged at connection
The rose reamer 4 of the bottom of bar 3, the blade 5 of the rose reamer 4 is set towards the bottom end face of the rotating shaft 1, and the connecting rod 3 is vertical
It is installed on the bottom end face of the rotating shaft 1, the distance between axial line of the axial line of the connecting rod 3 to the rotating shaft 1 is
The 1/4 of the diameter of the rotating shaft 1, the rose reamer 4 is arranged at the bottom outside of the connecting rod 3, and the rose reamer 4 away from institute
The axial line for stating rotating shaft 1 is set.
In the present embodiment, with rotating shaft not on same axial line, when in use, the axial line of rotating shaft can be with product for connecting rod
The through hole axial line of product overlaps, and during such axis of rotation, can carry out chamfering to the bottom of through hole by rose reamer.If directly will
Connecting rod is coaxially disposed with rotating shaft, and the diameter that the length of rose reamer then must be greater than through hole could fall to via bottoms
Angle, but the length of rose reamer is more than through-hole diameter, and rose reamer is then difficult to by through hole, it is difficult to carry out chamfering to via bottoms.
Therefore, chamfering effectively is carried out to via bottoms in the present embodiment, chamfering is carried out without overturning product repositioning, prevent secondary adding
The error of work positioning, improves through hole chamfer quality and efficiency.
Shown in Figure 1, the connecting portion 2 is provided with a positioning through hole 6, and the positioning through hole 6 is perpendicular to the rotating shaft 1
Axial line set.By the setting of positioning through hole, directly rotating shaft can be installed on the toolframe of machining center, be easy to produce
The processing of product.
The rose reamer 4 is set perpendicular to the connecting rod 3, the bottom of the medial surface of the rose reamer 4 and the connecting rod 3
Portion is connected, and the lateral surface 7 of the rose reamer 4 is set away from the axial line of the rotating shaft 1.So rose reamer is in rotating shaft
When the heart rotates, the diameter with diameter greater than product through hole that the lateral surface of rose reamer is rotated so can be using blade to product
Through hole carries out chamfering, realizes the bottom chamfer of product through hole.
The lateral surface 7 of the rose reamer 4 be arranged in parallel with the connecting rod 3, and the blade 5 of the rose reamer 4 is arranged at down
The top of angle knife 4, the outer end of the blade 5 is connected with the lateral surface of the rose reamer 4, the inner and company of the blade 5
Extension bar 3 is connected, and the angle between the blade 5 and the connecting rod 3 in 135 °~150 °.Wherein, blade and connecting rod it
Between angle according to the angle of product needed chamfering be adapted.
In the present embodiment, 1/4 of the diameter of the connecting rod less than the shaft diameter.
