Description
[technical field]
The utility model relates to mechanical manufacturing field, relates in particular to a kind of turning attachment.
[background technology]
Square block as shown in Figure 1, principal character is a lot of oil holes that distributing in it, and bears down in working order larger pressure.Wherein, the two flat holes that to have centre-to-centre spacing be 70 ± 0.3mm, be 17.5 ± 0.2mm apart from basal plane A are arranged on a plane, comprise inner bore chamfering with sealing function in two parallel holes, for the compound characteristics such as rounding (seeing Fig. 2, Fig. 3) of the screw thread, unthreaded hole and the stepped hole transition position that connect.As can be seen from Figure 1, the various morpheme dimensional requirements of two parallel holes are general, but in single hole each feature and compound required precision very high, as inner bore chamfering size, unthreaded hole aperture, mutual axiality, the rounding of stepped hole transition position etc.Want to meet compound characteristics numerous in single hole and corresponding required precision, each feature needs disposable machining.
[summary of the invention]
The problem existed for prior art, it is a kind of simple in structure, easy to operate that the purpose of this utility model is to provide, and can effectively guarantee the conforming turning attachment of processing dimension chain.
The technical solution adopted in the utility model is: a kind of turning attachment is characterized in that: comprise transition disc, locating piece, floating presure hold-down device, support pin, lock-screw and balancing weight; Wherein, transition disc is connected with lathe spindle; Locating piece is fixed on transition disc, is divided into locating piece a, locating piece b, locating piece c, locating piece d; During processing work, take locating piece b and basal plane A is locating surface; By floating presure hold-down device, support pin and the fixing workpiece of supporting lock-screw with it, then keep the gyration balance of transition disc by the increase and decrease balancing weight.
Further, described transition disc is connected with lathe spindle with screwing and respective screws hole by 6.
Further, described locating piece is fixed on transition disc by 2 with screwing and respective screws hole.
Further, described support pin and with it supporting lock-screw according to Working position, configure respectively.
The beneficial effects of the utility model are: simple in structure, easy to operate, guarantee the uniformity of processing dimension chain to have reduced again processing cost, and shortened process time, greatly improved production efficiency.

[specific embodiment]
Referring to accompanying drawing, the utility model is a kind of turning attachment, it is characterized in that: comprise transition disc 10, locating piece, floating presure hold-down device 9, support pin, lock-screw and balancing weight 15; Wherein, transition disc 10 is that circle is connected with lathe spindle; Locating piece is fixed on transition disc 10, is divided into locating piece a3, locating piece b4, locating piece c7, locating piece d8; During processing work 11, take locating piece b4 and basal plane A5 is locating surface; By floating presure hold-down device 9, support pin and the fixing workpiece of supporting lock-screw with it, then keep the gyration balance of transition discs 10 by increase and decrease balancing weight 15.
Described transition disc 10 is connected with lathe spindle with screwing and respective screws hole by 6.
Described locating piece is fixed on transition disc by 2 with screwing and respective screws hole.
Described support pin and with it supporting lock-screw according to Working position, configure respectively.
It is clamp body that the utility model adopts transition disc 10, utilize on transition disc 10 after the assembling of seam and machine tool chief axis, by at least 6 screws, through screw hole and lathe spindle on transition disc, tighten together, transition disc 10 adopts circular configuration, and overall structure symmetry, during mobile processing work 11, keep the balance of fixture gyration by position increasing and decreasing balancing weight 15.
While processing the first station, it is locating surface that locating piece b4 and basal plane A5 be take in workpiece 11 bottoms, with support pin a1 and locating piece a3 spacing after, hold out against square block by the lock-screw a2 corresponding with support pin a1, rotatably compress screw 16, utilize floating presure hold-down device 9 that square block is compressed, processed.
When processing the second station and being, support pin a1, lock-screw a2 dismantle, workpiece 11 is moved to right under the first station state, it is locating surface that locating piece b4 and basal plane A5 still be take in workpiece 11 bottoms, changes support pin b12 and lock-screw b13, according to counterweight, calculates and adds balancing weight 15, hold out against square block by the lock-screw b13 corresponding with support pin b12, rotatably compress screw 16, utilize floating presure hold-down device 9 that square block is compressed, processed.
