Abstract

The utility model discloses a kind of thin wall and deep holes to process special holder, it includes knife bar matrix, nut, transmission lasso, holding screw and reamer head, the front end of knife bar matrix is equipped with nut, keyway is provided in the nut front end of knife bar matrix, keyway is provided with key, transmission lasso is connected by key on knife bar matrix, and the hinged cutter head of the front end sleeve of knife bar matrix, holding screw is for fixed conveyor lasso in knife bar matrix.Using the special holder of the utility model, alloy standard reamer head is selected, is processed on drilling machine (lathe), replaced grinding, greatly improve efficiency, ensure that quality, drops bottom cost.There is no grinding undercut to profound ladder small blind hole simultaneously, be ground bad processing, and require high, it is also possible to which knife bar fraising on lathe is met the requirements.

Description

A kind of thin wall and deep hole processing special holder
Technical field
The utility model relates to a kind of processing special holders more particularly to a kind of thin wall and deep hole to process special holder.
Background technique
There are many ways to finishing of internal diameter, generallys use grinding, but grinding is slow, unstable product quality, And there is no grinding undercut simultaneously for profound ladder small blind hole, grinding is not.There is a product draw ratio greater than 7,2 millimeters of wall thickness Left and right.For this product thin wall and deep hole processing method, interior hole machined uses grinding, processing efficiency is low, unstable quality, Grinding wheel consumption is fast, causes at high cost.
Utility model content
To solve deep Hole processing slowly, unstable product quality problem, and deep small blind hole requirement are high, and grinding is not The technical issues of, the utility model provides a kind of thin wall and deep hole processing special holder.
The technical solution adopted in the utility model:
A kind of thin wall and deep hole processing special holder, it includes knife bar matrix, nut, transmission lasso, holding screw and reamer The front end of head, the knife bar matrix is equipped with nut, is provided with keyway in the nut front end of knife bar matrix, the keyway is provided with Key, the transmission lasso are connected by key on knife bar matrix, the hinged cutter head of front end sleeve of the knife bar matrix, the clamp screw Nail is for fixed conveyor lasso in knife bar matrix.
Further, the middle part of the knife bar matrix is straight-bar portion, and the front end in the straight-bar portion is followed successively by thread segment, keyway Section and small cone section, the rear end in the straight-bar portion are Morse's cone section.
Further, it is screwed with nut on the thread segment of the knife bar matrix, is cased with biography in the keyway section of the knife bar matrix Dynamic lasso.
Further, reamer head is cased on the small cone section of the knife bar matrix, the reamer head is connect with transmission lasso again.
Further, one end of the transmission lasso has boss, and the boss on the transmission lasso is connect with reamer head.
Compared with prior art, the utility model has the beneficial effects that using the utility model special holder, select alloy Standard reamer head is processed on drilling machine (lathe), is replaced grinding, is greatly improved efficiency, ensure that quality, drops bottom Cost.There is no grinding undercut to profound ladder small blind hole simultaneously, be ground bad processing, and require high, it is also possible to which the knife bar is in lathe Upper fraising, meets the requirements.

Specific embodiment
In order to deepen the understanding to the utility model, with reference to the accompanying drawing and specific embodiment is described in detail, this Embodiment described in specification is only used for explaining the utility model, is not used to limit the utility model.
Shown in Fig. 1, Fig. 2, a kind of thin wall and deep hole of the utility model processes special holder, including knife bar matrix 1, nut 2, Transmission lasso 3, holding screw 5 and reamer head 6, the front end of knife bar matrix 1 are equipped with nut 2, before the nut 2 of knife bar matrix 1 End is provided with keyway 8, and keyway 8 is provided with key 4, and transmission lasso 3 is connected on knife bar matrix 1 by key 4, the end of knife bar matrix 1 It is cased with reamer head 6, holding screw 5 is for fixed conveyor lasso 3 in knife bar matrix 1.
The middle part of above-mentioned knife bar matrix 1 is straight-bar portion 11, and the front end in straight-bar portion 11 is followed successively by thread segment 12,13 and of keyway section Small cone section 14, the rear end in straight-bar portion 11 are Morse's cone section 15.
It is screwed with nut 2 on the thread segment 13 of knife bar matrix 1, transmission lasso 3 is cased in keyway section 13.
Reamer head 6 is cased on the small cone section 14 of knife bar matrix.Reamer head 6 is connect with transmission lasso 3 again.
Shown in Fig. 3, one end of transmission lasso 3 has boss 31, and the boss 31 being driven on lasso 3 is connect with reamer head 6.
By the knife bar combined on lathe, product 7 is fixed on to the other end of opposite knife bar, starting lathe can add Chemical product.
When processing deep step small blind hole, hole surplus is few as far as possible, can twist out, while at the aperture angle Yin Daoyin, then Twist and cuts.
The special holder of the utility model loads onto nut 2 respectively on knife bar matrix 1, is driven lasso 3 on set, and with key 4 Will transmission lasso 3 be connected on knife bar matrix 1, further according to inner hole size choose 6 sets of reamer head on knife bar matrix 1 and with transmission The connection of 3 convex platform 31 of lasso, is then loaded on holding screw 5.It can converted products on lathe by the tool cover installed.It is applicable in Using the knife bar of finishing inner hole on drilling machine and lathe, improve efficiency, to stepped hole and aperture deeply and is relatively the product of blind hole, Reamer head can also be chosen with this kind of knife bar in lathe process.
