Abstract
The utility model provides a clamp for milling rotor bearing shells. The clamp comprises a bottom plate, wherein V-shaped iron is fixed on the bottom plate; a fixed screw hole and guide pillars are arranged on the V-shaped iron; a frame-type platen is arranged on the guide pillars; a fixed hole corresponding to the fixed screw hole of the V-shaped iron is manufactured on the frame-type platen; and a compression bolt is arranged in the fixed screw hole and the fixed hole. The clamp has the following beneficial effects: the bottom plate, the V-shaped iron fixed on the bottom plate and the frame-type platen which is connected with the V-shaped iron form the multi-position clamp; the clamp is installed in the position of the original square tool post of the lathe and can ensure that the lathe can carry out milling in combination with a milling part installed between a three-jaw chuck and a tail tip; the application range of the lathe is expanded and the working efficiency is improved; and a plurality of machining workpieces can be fixed in the clamp once, thus improving the machining efficiency manyfold.
Description
Technical field
The utility model relates to a kind of milling attachment that is used for lathe, uses this device and can enlarge the lathe scope of application, solves to lack the milling machine problem.
Background technology
The situation that needs batch machining shell type part is often arranged in commercial process, and a common small processing enterprise promptly has and produces per year tens thousand of or hundreds thousand of single parts need be processed, like the small-size shaft bearing sleeve etc.; Common sleeve surface one side of this type part often has several facets need carry out Milling Process; The method of prior art is to clamp workpiece with three-jaw one division head, singlely on vertical knee-type milling machine, carries out milling, and production efficiency is extremely low; Processing cost is high, is difficult to satisfy the demand.If increase milling machine quantity, because of milling machine use single, when the workpiece lazy weight; Can form idlely again, and all there are some lathes in general processing enterprise, if lathe is used to remedy the milling machine lazy weight; Then can temporarily idle lathe be come into operation, improve utilization ratio.
Summary of the invention
The utility model provides a kind of rotor bearing shell to mill and has used anchor clamps, has solved the problem that substitutes the milling machine processing parts with engine lathe, has both improved the lathe utilization rate, and also having solved does not have milling machine or the not enough problem of milling machine.
A kind of rotor bearing shell of the utility model mills uses anchor clamps; Comprise base plate; On base plate, be fixed with v block, fixing threaded hole and guide pillar are arranged on v block, on guide pillar, be with the frame pressing plate; On the frame pressing plate, be shaped on the fixing hole corresponding, in fixing threaded hole and fixing hole, hold-down bolt arranged with the fixing threaded hole of v block.
Described rotor bearing shell mills uses anchor clamps, it is characterized in that a side of v block is provided with location-plate, and vertical plate bottom is provided with little pressing plate in the both sides of frame pressing plate, is with back-moving spring on the described hold-down bolt.
Described rotor bearing shell mills uses anchor clamps, and wherein little pressing plate and frame pressing plate are hinged, and described little pressing plate cross sectional shape is a triangle.
Described rotor bearing shell mills uses anchor clamps, it is characterized in that cutterhead quantity is three.
The rotor bearing shell of the utility model mills uses anchor clamps; Through base plate and be fixed on the v block on the base plate and the frame pressing plate that links to each other with v block formation clip tool more than; These anchor clamps are installed in the former squaring head of lathe position, and the milling parts that combine simultaneously to be installed between scroll chuck and the tail point can make lathe carry out milling operation.Enlarge the scope of application of lathe, improved operating efficiency.Can once fix a plurality of processing works in the anchor clamps, improve working (machining) efficiency exponentially.
Description of drawings
Fig. 1 mills to use the clamp structure sketch map.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is a milling modular construction sketch map.
Among the figure, 1-base plate, 2-V sections, 3-guide pillar, 4-back-moving spring, 5-nut, 6-packing ring; The 7-hold-down bolt, 8-frame pressing plate, the little pressing plate of 9-, 10-workpiece, 11-knife bar, 12-scroll chuck, 13-cutterhead; The 14-locating sleeve, 15-is top, 16-hinge, 17-packing ring, 18-locking nut, 19-location-plate.
The specific embodiment
Below in conjunction with accompanying drawing the utility model rotor bearing shell is milled with anchor clamps and to do detailed description.
Many clips of accompanying drawing 1-2 tool front view and vertical view; These jig main body parts are by a base plate 1 shown in the figure; V block 2 constitutes with frame pressing plate 8, and wherein v block 2 is fixed on the both sides of base plate 1, on both sides v block 2, is provided with several V-type grooves; And each V-type groove all keeps being coaxially set with the V-type groove of offside, and each is to placing a workpiece on the V-type groove.There is fixing threaded hole at the middle part of v block 2 in both sides, and the correspondence position of the vertical plate in both sides of frame pressing plate 8 is shaped on fixing hole, and hold-down bolt 7 links together frame pressing plate 8 and bottom v block 2 and base plate 1 through said fixing hole and fixing threaded hole.Behind place work piece on the v block, frame pressing plate 8 is fastening with nut.In order to prevent 8 swings of frame pressing plate, near four end points of v block, be fixed with guide pillar 3 respectively, correspondence position is provided with pilot hole on four angles of frame pressing plate 8.Pile up accurately for the ease of workpiece, also be fixed with location-plate 19 in a side of v block 2.
During work; Through two elongated slot on the base plate 1 many clips tool is fixed on the position of lathe squaring head (laying down squaring head in advance); Workpiece 10 is installed in the V-type groove of v block 2; End face and location-plate 19 are close to the realization location, and frame pressing plate 8 gives pressure by hold-down bolt secondary (two ends all are shaped on screw thread hold-down bolt 7, packing ring 6, form with nut 5).Frame pressing plate 8 is compressed the workpiece two ends.Another kind of embodiment is in that vertical plate bottom is delivered on the workpiece through little pressing plate 9 by the pressure of hinge 16 with pressing plate 8 by the little pressing plate 9 of hinge fixed triangle shape in the both sides of frame pressing plate 8.
Shown in Figure 3, cutterhead 13 is installed on the knife bar 11 of milling parts, select cutterhead 13 according to the processing request of workpiece, the quantity of cutterhead is installed confirms according to the quantity that needs machined surface on the workpiece.If need two planes of processing on the workpiece; Two cutterheads 13 then are installed,, the locating sleeve 14 of equal length are set between two cutterheads promptly according to the machined surface distance; And this is installed on the knife bar 11; Pad upper gasket 17, fastening nut 18 is installed on this on scroll chuck 12 and the tailstock centre 15 then in the lump.
During work, the milling parts are cutterhead 13 rotations, and then connect synkinesia, send workpiece to through cross slide and do feed motion.
V block 2 as a whole being fixed on the base plate among another embodiment of the utility model.
