Description
Technical field
The present invention relates to a kind of reaming bit.
Background technology
In the cutting process such as glass, ceramics, stone material, often use reaming bit and glass, ceramics, stone material are bored
Hole, but suitable drill bit is equipped with according to specific boring aperture every time, it is very inconvenient, also increase and purchase drill bit
Quantity and cost.In addition, after alloy cutter head blunt on reaming bit, whole drill bit also can not be just continuing with, bore
The matrix of head is scrapped, and causes certain waste.Additionally, it is sometimes desirable to carry out reaming, edging successively to material to be processed, fall
Angle operation, traditional operating type is carried out successively using different drill bits, between different work will more bit change, so not
Only efficiency is low, and in more bit change, it is difficult to ensure concentricity, cause crudy to be difficult to control to.
The content of the invention
The purpose of the present invention is to propose to a kind of expansion bit of detachable cutter head, to improve efficiency, cost is reduced.
The expansion bit of the detachable cutter head of the present invention includes matrix, and matrix is provided with for consolidating for being connected with driving part
Dead axle；Key is that described matrix is provided with centered on fixing axle, and several grooves radially distributed, matrix is provided with edge
The sliding block of groove movement, the sliding block is provided with the fastener for being used for being fixedly connected with matrix, and sliding block is removably provided with cutter head.
In the reaming for different-diameter（Or edging, chamfering）Deng operation when, adjust it beforehand through mobile sliding block
Spacing between fixing axle, so as to adjust the distance between cutter head and fixing axle, changes the diameter of drill bit, after the completion of adjustment
Sliding block is integrally fixed with matrix using fastener, you can carry out corresponding operation., can will be old after cutter head weares and teares
Cutter head is dismantled, the cutter head more renewed, without sliding block and matrix are scrapped, so as to save cost.
Further, the angle between adjacent groove is identical, so the active force suffered by each cutter head can be made identical, mill
Damage speed identical, and improve reaming quality.
Further, scale groove of the described matrix provided with a plurality of concentric circles by the center of circle of fixing axle, adjacent scale
Diameter difference between groove is identical.Adjust sliding block position when, preferably using disk as a reference to sliding block progress it is spacing, make
The diameter of disk is with treating reaming（Or edging, chamfering）Diameter it is identical, then sliding block and disk are offseted again and sliding block is fixed,
Scale groove can certainly be utilized as a reference to the position of adjustment sliding block, although so limited precision, is adjusted more square
Just.
Specifically, the sliding block is by flat sliding part and the cutter head mounting blocks structure being perpendicularly fixed on sliding part
Into the cutter head utilization sequentially passes through cutter head and the bolt of cutter head mounting blocks is removably installed on sliding block, the sliding part
It is in contact with matrix, the fastener is the bolt for sequentially passing through sliding block and groove.Tool bit abrasion to a certain extent after, can be with
Cutter head is pulled down from cutter head mounting blocks and changed, without sliding block is changed together, efficiency is further increased, reduces
Cost.After unclamping as the bolt of fastener, you can sliding block is moved relative to matrix, to change the position of sliding block.
Further, the groove is the step trough that cell wall is provided with step, and the sliding part is provided with and stretched in groove
Locating piece, the end of the locating piece offsets with the step, and the both sides of locating piece and the cell wall of groove offset.Above-mentioned locating piece
Extend into groove, for sliding block can provide support force in matrix rotation direction, anti-limited slip block in operation process relative to
Matrix is rocked, so as to improve reliability, the stability that the accuracy and cutter head of operation are installed.
Further, the side of the cutter head mounting blocks away from fixing axle is the mounting surface of arc, the installation of the cutter head
Portion towards the side of cutter head mounting blocks be cambered surface；The cambered surface and mounting surface of the cutter head are using fixing axle as the center of circle.So making
During industry, the impulsive force suffered by cutter head can improve the stabilization that cutter head is connected with sliding block perpendicular to the bolt of fixed cutter head
Property.
Further, the cutter head includes separate reaming cutter and edging chamfering cutter head, the edging rose reamer
The work department of head is made up of the edging portion and the chamfered section between edging portion and installation portion of end, the end in the edging portion
Than reaming cutter end closer to matrix, and the outer ledge in edging portion is located farther from base than the external margin of reaming cutter
The center of body.By above-mentioned setting, in the course of work of drill bit, mill of the end prior to edging chamfering cutter head of reaming cutter
Edge is in contact with material to be processed, i.e., drill bit first carries out ream operation, after the completion of ream operation, edging chamfering cutter head
Edging portion is in contact with material, proceeds by edging operation, after the completion of edging operation, the chamfered section and material of edging chamfering cutter head
Material is in contact, and proceeds by chamfering operation, thus once completes the different processing operation of reaming, edging, three kinds of chamfering, no
It improve only in operating efficiency, and three kinds of operations without again being positioned drill bit, it is ensured that reaming, edging, chamfering
Concentricity, improve crudy.More it is essential that after abrasion occurs in the lateral surface of edging chamfering cutter head（Edging and fall
Angle operation is carried out using the lateral surface of edging chamfering cutter head）, can be to the position of external-adjuster edging chamfering cutter head, it is ensured that edging
The outer ledge in portion is located farther from the center of matrix than the external margin of reaming cutter, normally reaming, edging, chamfering can make
Industry, without changing edging chamfering cutter head, saves cost.
Further, reaming cutter and edging the chamfering cutter head is arranged at intervals, to cause drill bit stress in operation equal
It is even, and improve operation effectiveness.
Specifically, the work department of the reaming cutter is arc tabular, so that rushing suffered by cutter head in operation process
Power is hit parallel to cutter head, reaming quality is improved.
Edging portion in the edging chamfering cutter head is arc tabular, and the lateral surface of chamfered section is provided with outstanding in edging
The inclined-plane in portion, the contact surface of cutter head and material when inclined-plane is chamfering.
The expansion bit of the detachable cutter head of the present invention is simple in construction, its working diameter it is easy to adjust quick, work is straight
The precision in footpath can be effectively ensured, and the stable connection of cutter head and matrix is reliable, and can be carried out reaming, edging simultaneously, be fallen
Angle operation, it is possible to extend the service life of edging chamfering cutter head by way of adjusting edging chamfering cutter head position, reduction
Use cost, is very suitable for the ream operations such as glass, ceramics, stone material.
