Abstract
The utility model discloses a machine tool fixture for machining a symmetric fork type shaft-like part, comprising a fixture body. The fixture body comprises a bottom plate; clamping shafts are systematically arranged above the front side and the back side of the bottom plate; the clamping shafts are fixedly connected on the bottom plate by a support seat; and screw holes are arranged on the baseboard. When the machine tool fixture operates, the machine tool fixture is fixed on a main shaft flange of the machine tool by bolts through the screw holes, so that the fork part of the symmetric fork type shaft-like part (such as a fork type spline shaft) is supported against on the bottom plate; at that moment, the fork part of the part to be machined is clamped by the clamping shafts on the front side and the back side of the bottom plate. Compared with the prior clamping method by a V-shaped position iron, as the clamping shafts and the symmetric fork type shaft-like part are in lineal contact, the machine tool fixture can clamp more firmly and is not easy to slide.
Description
Technical field
The utility model relates to a kind of turning attachment, especially is used for processing the turning attachment of symmetric figure V shape axle shape machine components.
Background technology
For a long time, the turning attachment that is used for processing those symmetric figure V shape axle shape machine components adopts the V shape iron locate mode of traditional classical always, and is unalterable; Certainly this is a kind of very effective locate mode, and comparatively simple, and it is the some contact with contacting of workpiece, and slides easily between the workpiece.The blank of symmetric figure V shape axle shape machine components adopts casting or forging molding often, mostly its mould is to adopt the intermediate section pattern, the phenomenon of axial mismatch more or less can appear in the blank of therefore casting or forging, relatively poor with the part symmetry that the turning attachment of traditional V shape iron locate mode processes, often can not guarantee the specification requirement of pattern, particularly when " sliding york " in the processing automobile power transmission shaft and " spline joint " part, occur axially offsetting because forge the blank that comes out exactly, the part symmetry that causes processing can not satisfy the requirement of pattern, lays particular stress on when finally doing dynamic balancing to lose efficacy and scrap.
At present, when symmetric figure V shape axle shape machine components blank axial offsetting occurs and is unlikely to scrap again, there is not a kind of effective clamp structure form on the market, guarantee the part that is processed, with two faces of part axial line quadrature in, the complete coincidence pattern specification requirement of its symmetry.
The utility model content
The purpose of this utility model is to provide a kind of turning attachment that is used to process symmetric figure V shape axle shape part, and it is firm to piece-holder to add man-hour anchor clamps, sliding phenomenon can not take place.
For achieving the above object, the turning attachment that is used to process symmetric figure V shape axle shape part of the present utility model comprises clamp body, and clamp body comprises base plate, and the top of both sides is arranged with clamp axis before and after the base plate, and clamp axis is fixedly connected on the base plate by bearing.
The base plate middle part is provided with the through hole that is used for by the lathe spindle tapered sleeve, and the top slide that the main shaft tapered sleeve stretches out throughhole portions is connected with the roof pressure piece, and roof pressure piece left and right side is a cambered surface, and the fork intrados of this cambered surface and symmetric figure V shape axle shape part is complementary.
Described base plate is provided with screw, and screw is used for base plate is screwed onto the spindle flange of lathe.
The utlity model has following advantage:
1. use bolt the utility model to be fixed on the spindle flange of lathe when working by the screw on the base plate, on base plate, the clamp axis of both sides just clamps the fork of part to be processed before and after this moment base plate with the fork roof pressure of symmetrical V shape axle shape part (as the V shape splined shaft).Because for line contact, therefore V-arrangement detent rail (point contacts) clamping more in the past is more firm, difficult slip between clamp axis and the symmetrical V shape axle shape part.
The roof pressure piece the further clamping effect of the utility model to the fork of part to be processed that strengthened be set, the fork of part to be processed can not slided.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the plan structure schematic diagram of Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2, a kind of turning attachment that is used to process symmetric figure V shape axle shape part of the present utility model comprises clamp body, and clamp body comprises base plate 1, the top of both sides, base plate 1 front and back is arranged with clamp axis 2, and clamp axis 2 is fixedly connected on the base plate 1 by bearing 3; Base plate 1 is provided with four screws 4, and screw 4 is used for base plate 1 is screwed onto the spindle flange of lathe.
Use bolt the utility model to be fixed on the spindle flange of lathe during work by screw 4, on base plate 1, this moment, the clamp axis 2 of both sides, base plate 1 front and back just clamped the fork 8 of part to be processed with fork 8 roof pressures of symmetrical V shape axle shape part (as the V shape splined shaft).Because for line contact, so V-arrangement detent rail (put and contact) clamping more in the past is more firm between clamp axis 2 and the symmetrical V shape axle shape part.Simultaneously, as shown in Figure 1, roof pressure piece 7 from the inboard of the fork 8 of symmetrical V shape axle shape part and this fork intrados 7B roof pressure mutually, has further strengthened the clamping effect of the utility model to part to be processed by its left and right sides cambered surface 7A.
