Description
Technical field
The present invention relates to work pieces process technical field, especially a kind of small lot threeway work pieces process turning attachment.
Background technology
Threeway workpiece is processed, is always the problem in turnery processing.Common method is the single centering on chuck,
Each end face processing, the method so done cause the precision for processing workpiece or geometric tolerance to depend on the operator of equipment,
Processing quality cannot be guaranteed.In the case of producing threeway workpiece in enormous quantities, then turning equipment can be transformed, be equipped with equipment
Hydraulic pressure or pneumatic index chuck can directly be indexed after so processing one end by index chuck, and conversion needs to process threeway
The end face of workpiece, this large batch of production method can ensure the geometric tolerance of threeway workpiece.But small lot threeway workpiece
Clamping method it is still urgently to be resolved hurrily.
The content of the invention
The technical problem to be solved by the present invention is to：It proposes a kind of small lot threeway work pieces process turning attachment, passes through folder
The design of tool enables the clamping of threeway workpiece to realize fast and accurate positioning under the auxiliary of fixture；Fixture is easy to simultaneously
It realizes, simplifies clamp mechanism.
The technical solution adopted in the present invention is：A kind of small lot threeway work pieces process turning attachment, including clamp body
And threeway workpiece keeps seat；The threeway workpiece keeps placing threeway workpiece in seat；The clamp body is mounted on numerical control
On lathe, one end of clamp body passes through 1:20 tapers with latching characteristics are engaged with inner hole of spindle；The other end of clamp body
It sets fluted；The threeway workpiece keeps seat to be positioned in groove；The top surface that clamp body has reeded one end is set
It is equipped with lock-screw；The reeded bottom of clamp body is provided with threeway workpiece and keeps seat alignment concavity.
Further, it is the rectangular block with notch that threeway workpiece of the present invention, which keeps seat,；Threeway workpiece is kept
The top of seat is provided with locking countersunk head threaded hole；Threeway workpiece keeps the bottom of seat to be provided with and keeps seat positioning surface convex surface；Threeway
Workpiece keeps seat by keeping the threeway workpiece on seat positioning surface convex surface and clamp body that seat alignment concavity is kept to be connected.
It further says, threeway workpiece of the present invention is positioned over threeway workpiece and keeps in the notch of seat.
The beneficial effects of the invention are as follows：
1st, on numerically controlled lathe, the biographies such as scroll chuck, chuck, floral disc can only be used by changing centre numerically controlled lathe
The limitation of system fixture expands the range of work of numerically controlled lathe, while the precision of fixture is far beyond the precision of universal fixturing.
2nd, the installation on numerically controlled lathe uses 1:20 taper positioning, threeway workpiece lathe fixture and main shaft is strictly same
The heart ensure that the circle bounce and total run-out of fixture, advantageously ensure that the circularity of the threeway workpiece of processing, be more advantageous to ensureing threeway
The geometric tolerance of three end faces of workpiece.
3rd, seat is kept using threeway workpiece, when realizing crossover tee workpiece difference end face, threeway workpiece need not be dismantled,
With keeping converting together with seat, the geometric tolerance between three end faces is advantageously ensured that, after effectively solving three end face conversions
The technical barrier that workpiece needs correct.

Specific embodiment
Presently in connection with attached drawing and preferred embodiment, the present invention is described in further detail.These attached drawings are simplified
Schematic diagram only illustrates the basic structure of the present invention in a schematic way, therefore it only shows composition related to the present invention.
A kind of small lot threeway work pieces process turning attachment keeps seat including clamp body and threeway workpiece；Described
Threeway workpiece keeps placing threeway workpiece in seat.
Clamp body is as shown in Figure 1, clamp body passes through 1 on numerically controlled lathe:20 have the taper of latching characteristics and master
Axis endoporus is engaged so that entire process engineering is not in the situation that clamp body has skidded with inner hole of spindle, ensure that and adds
Work is normally carried out, if carrying out heavily loaded turning, fixture can be firmly locked at main shaft by M20 clamp body locking screws
In endoporus, meanwhile, M20 clamp body locking screws can be used for clamper for disassembling body.Seat positioning surface is kept to keep seat for workpiece
Positioning, the center line of positioning surface ensure that hanging down between three end faces of threeway workpiece strictly by the center line of clamp body
Directly, the concentric of two of which end face is also ensured.M10 keeps seat lock-screw seat can be kept to lock in clamp body workpiece
It is interior, while unclamp M10 and keep seat lock-screw that can easily convert different processing end faces.
Threeway workpiece keeps seat as shown in Fig. 2, being put into a threeway workpiece in threeway workpiece installing zone, Workpiece structure is such as
Shown in Fig. 3, the placement of workpiece ensures with keeping seat symmetrical.Threeway workpiece locking countersunk head threaded hole can lock threeway workpiece
Threeway workpiece is kept in seat, ensures situations such as being not in loosening in turnery processing.Workpiece keeps seat positioning surface and clamp body
On holding seat positioning surface be engaged, ensure that the interchangeability of three end faces of workpiece, as Figure 4-Figure 6, in process engineering not
Threeway workpiece is needed dismantle to turn around, need to only unclamp locking countersunk head screw thread, turning of work piece is kept.
This fixture designs the Main Analysis geometrical property of threeway workpiece, and three end faces for obtaining threeway workpiece are in
What the heart rotated, so designing this sleeve clamp so that process different end faces, use same numerical control program.
The specific embodiment of the simply present invention described in description above, various illustrations are not to the reality of the present invention
Matter Composition of contents limits, and person of an ordinary skill in the technical field can be to described in the past specific after specification has been read
Embodiment is made an amendment or is deformed, without departing from the spirit and scope of the invention.
