Abstract

The utility model discloses a tool of a computer numerical control (CNC) gear grinding machine for machining a gear shaft. The main body of the tool adopts a V shape face structure, a fixing hole is arranged on the outer surface of the bottom end of the V shape, extending arms at two ends of the V shape are parallel to an axis of the fixing hole, and gripping combined mouths are arranged on the extending arms of the two ends of the V shape. According to the tool, when workpiece is mounted and clamped by clamping hoops, two clamping hoops form a group of clamping tools, preloaded double-head bolts on two sides of each clamping tool are combined on the clamping hoops from the outer side in a gripping combined mode, the V shape face with 120 degrees angle is tightly attached to a shaft neck position of the gear shaft, the contact area of square flat cushions disposed under nuts of the double-head bolts and the surfaces of the clamping hoops is big and an anti-loosening effect is good. The tool of the CNC gear grinding machine for machining the gear shaft is simple in structure, low in cost, easy to manufacture, and capable of adjusting size dimension according to different shaft neck sizes, and therefore the adjusting scope is big, the adjusting scope of the clamping hoops is increased, machining efficiency of the gear grinding machine is greatly improved, and work intensity of labors is reduced.

Description

The frock of numerically controlled tooth grinding machine processing tooth axle

Technical field

The utility model belongs to plant equipment manufacturing technology field, relates to the used a kind of frock of numerically controlled tooth grinding machine process, is specifically related to a kind of frock of numerically controlled tooth grinding machine processing tooth axle.

Background technology

The clip that numerically controlled tooth grinding machine processing tooth axle uses, traditional process was to use according to the clip that the difference of the place of being installed tooth shaft neck is processed respectively different size in the past, and the scope that each clip uses is in ± 1mm, and the clip quantity of use is many like this, and manufacturing cost is very high.

Summary of the invention

The frock that the purpose of this invention is to provide a kind of numerically controlled tooth grinding machine processing tooth axle solves the numerically controlled tooth grinding machine processing tooth axle limited problem that is installed.

The technical scheme that the utility model adopts is, a kind of frock of numerically controlled tooth grinding machine processing tooth axle, main body adopts V-type face structure, and the V-type bottom outer surface is provided with fixing hole, the cantilever arm at V-type two ends is parallel with the fixing hole axis, and V-type two ends cantilever arm is provided with healing up.

The beneficial effects of the utility model are, numerically controlled tooth grinding machine uses this frock can reduce the use of many clips, greatly improve the working (machining) efficiency of numerically controlled tooth grinding machine, specifically comprise: (1) self structure is simple, shape is easy to processing and manufacturing, the about 2KG of quality, light handled easily can be quickly installed on the workpiece.(2) owing to existing clip is the enclosed construction reason, can only be before clamping tooth axle, just install before noting be used in clamping workpiece after the improvement, the pretension screw is convenient to closing in both sides, adopt the open type structure, rapidly fixing hoop, very easily jointing clip on workbench.(3) pit one against tenEvery man is worth ten, the clip adjusting range is large, can replace the clip of many fixed dimensions, has saved resource, raises the efficiency.

Among the figure, 1. go up top, 2. workpiece, 3. knife rest, 4. column, 5. emery wheel, 6. block, 7. lathe bed, 8. time top, 9. clip, 10. rear column, 11. workbench, 12. existing clips, 13. healing up 14. fixing holes, 15. cantilever arms.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is elaborated.

As shown in Figure 1, be the structural representation of existing clip 12, closing, the tooth axle of dress fixed diameter in the hole has clip 12 now and is screwed on workbench 11 with bearing 6 by the pretension screw in the front-loading hole.Existing clip 12 since structure institute limit scope can only

Use in the scope.

As shown in Figure 2, figure a wherein is the schematic front sectional view of clip 9, and figure b is the top cross sectional view of clip 9.Clip 9 of the present utility model is capable of regulating diameter clip, and the main body of clip 9 adopts the V-type face of hexagonal angle degree, and this V-type face is used for contacting the location firmly with cylindrical journal; The V-type bottom outer surface is provided be used to the fixing hole 14 that installs hold-down screw, the cantilever arm 15 at V-type two ends is parallel with fixing hole 14 axis, V-type two ends cantilever arm 15 is provided with to be convenient to pretension the handle that closes screw is healed up 13, the 13 employing open type structures of healing up, can install rapidly the stud that closes so that fixing hoop is easy and simple to handle.The clip material is 45 steel, and heat treatment hardness is HB241～286.

As shown in Figure 3, clip 9 of the present utility model is when card engaging workpiece 2, form one group of jig by two clips 9, both sides pretension stud heals up on 13 from the outside closing in the handle of two ends cantilever arm 15, the V-type face of hexagonal angle degree closely is affixed on tooth shaft neck place, the square plain cushion of placement and clip face contact area are large and locking good under the nut of stud, have formed so firm being installed.

As shown in Figure 4, clip 9 of the present utility model is behind the workpiece 2 that has been installed, during grinding tooth axle with workpiece 2 vertical clampings on the workbench 11 of vertical numerical control gear grinding machines, workpiece 2(tooth axle) upper centre bore cooperates with upper top 1 of rear column 10, the lower centre bore of workpiece 2 with place numerically controlled tooth grinding machine workbench 11 on lower top 8 cooperate.The grinding motion of grinding tooth axle is the resultant motion that rotatablely moves by high speed rotary motion and the workbench 11 of emery wheel 5.The effect of clip 9 is exactly that the fixing block 6 that moves through on the workbench 11 with workbench 11 passes to workpiece 2 like clockwork, workbench 11 is two direction rotations when work, not allowing in the whole process has drive gap when changing direction, there is not backlass in the middle of guaranteeing, so clip 9 will firmly tight and clip self also will be so closing with block 6.

Because existing clip is enclosed construction, can only before clamping workpiece 2, after installing change can not be arranged again outside workbench, and the utility model is open architecture, can after workpiece 2 clampings are installed to workbench, install and fix again clip, close by two studs handles.

The utility model is simple in structure, and cost is low, and is easy to manufacture, can adjust size according to different journal sizes, so adjusting range is large, can satisfy the processing for the tooth axle of various different size axle journals.Numerically controlled tooth grinding machine no longer is subjected to the restriction of a plurality of fixing hoops, has strengthened the adjusting range of clip, has greatly improved the working (machining) efficiency of gear grinding machines.
