Description
Technical field
The utility model relates to a kind of Vehicle Processing frock, specifically a kind of swash plate support semi arch Vehicle Processing frock.
Background technology
At present, in China's field of machining, processing semi arch workpiece generally all is to adopt method for turning processing circular arc, and its principle is that lathe tool point of a knife movement locus is a circular arc, and arc radius and forming face arc radius equate.During turning, work centre line should be at grade.Installation can be carried out the specific purpose tool or the anchor clamps of gyration, size cambered surface.Present existing frock clamp is when turning, and No. one time clamping can only be accomplished side processing, needs the secondary clamping could accomplish the circular arc turning of opposite side, owing to need the secondary clamping, so can not satisfy the requirement of swash plate support special construction and processing technology.
In view of this, to the problems referred to above, propose a kind of reasonable in design and effectively improve the swash plate support semi arch Vehicle Processing frock of above-mentioned disappearance.
Summary of the invention
The purpose of the utility model is to provide a kind of swash plate support semi arch Vehicle Processing frock; In the time of can effectively solving turning processing both sides circular arc; Workpiece need be changed the secondary clamping; And secondary clamping and the positioning accuracy that causes is not high, machining deviation does not reach the form and position tolerance and the processing work size problem of unstable of workpiece technological requirement.
In order to reach above-mentioned purpose, the utility model provides a kind of swash plate support semi arch Vehicle Processing frock, comprising: a clamp body, this clamp body rear end are connected with machine tool chief axis and same with it axle center; The bottom lining plate that one clamp body front end connects, the shape of this bottom lining plate is identical with the location basal plane of swash plate support, is buckled in the swash plate support on the bottom lining plate; The front end of bottom lining plate and be provided with the movable locating device that is used for to swash plate support location with the clamp body same axis; Perpendicular to bottom lining plate and the opening pressing plate and the nut that are provided with the mandrel that passes the swash plate support and are used for clamping the swash plate support with swash plate support same axis.
Said movable locating device by bolt, be enclosed within the nut on this bolt, the limiting plate in this nut the place ahead constitutes.
Said bottom lining plate is fixed on the clamp body with hexagon socket head cap screw, and bottom lining plate and clamp body adopt the structure that is separated.
The thickness of said clamp body and bottom lining plate is the circular arc center of circle 2 times to spacing basal plane distance, makes clamping retread disc carrier two workpiece circular arcs on same diameter circle.
Clamp body through bolt and machine tool chief axis be linked together, and through taper bolt anchor clamps and machine tool chief axis are positioned simultaneously, the assurance clamp body is concentric with main shaft.
Compared to existing apparatus; The utility model has been optimized the structure of whole anchor clamps; Adaptable across machined numerically controlled lathe and engine lathe; And a clamping can be accomplished the processing of all semicircle cambered surfaces of two swash plate supports, has improved the production efficiency of part, has effectively guaranteed the precision of accessory size and form and position tolerance.Fundamentally solved the not high and low problem of production efficiency of the positioning accuracy that causes owing to the secondary clamping; The technological requirement and the stability that improves workpiece size of workpiece have effectively been satisfied; This frock overall performance is stable, adapts to the needs of producing in batches; Simultaneously because this device adopts the structure that clamp body is connected with main shaft and the use of opening pressing plate, the assembling of workpiece, dismantle very conveniently, reduced labour intensity.

[main element symbol description]
The specific embodiment:
Detailed description of relevant the utility model and technology contents, conjunction with figs. are explained as follows, yet accompanying drawing only provides the usefulness of reference with explanation, are not to be used for the utility model is limited.
Please with reference to Fig. 1, Fig. 2 and Fig. 3, a kind of swash plate support semi arch Vehicle Processing frock comprises: a clamp body 1, this clamp body rear end are connected with machine tool chief axis 12 and same with it axle center; Clamp body through hexagon socket head cap screw 2 and machine tool chief axis be linked together, and position through 3 pairs of anchor clamps of taper bolt and machine tool chief axis simultaneously, the assurance clamp body is concentric with main shaft.The bottom lining plate 4 that one clamp body front end connects, said bottom lining plate is fixed on the clamp body with hexagon socket head cap screw 5, and bottom lining plate and clamp body adopt the structure that is separated.The shape of this bottom lining plate is identical with the location basal plane of swash plate support, is buckled in the swash plate support on the bottom lining plate; The front end of bottom lining plate and be provided with the movable locating device that is used for to swash plate support location with the clamp body same axis; Perpendicular to bottom lining plate and the opening pressing plate 7 and the round nut 6 that are provided with the mandrel 8 that passes the swash plate support and are used for clamping the swash plate support with swash plate support same axis.Swash plate support medial surface and bottom surface are cooperated be matched in clearance, 5 frees degree of restriction workpiece.Consider the particularity (both sides processing) and the design of Clamping Apparatus structure of machined surface, then the design activity positioner, said movable locating device by bolt 9, be enclosed within the nut 10 on this bolt, the limiting plate 11 in this nut the place ahead constitutes.The thickness of said clamp body and bottom lining plate is the circular arc center of circle 2 times to spacing basal plane distance, makes clamping retread disc carrier two workpiece circular arcs on same diameter circle.
In the middle of present embodiment, movable locating device: bolt 9, nut 10, limiting plate 11.Certainly movable locating device is not defined as that this is a kind of.According to the movable locating device shown in Fig. 1, Fig. 2 and Fig. 3, bolt 9 is fixed on the limiting plate 11 through nut 10, regulate the relative position of bolt 9 and nut 10, the swash plate support is positioned.Through round nut 6 and opening pressing plate 7 the swash plate support is clamped.During clamping, design mandrel locking device is locked mandrel through nut, prevents the rotation of mandrel 8.After treating that workpiece clamps, take out movable locating device bolt 9, nut 10, limiting plate 11, prevent resetting, follow 6 rules in the frock design.The lathe tool that utilizes lathe left side is processed semicircle cambered surface φ 1, the φ 2 of swash plate support left end; The lathe tool that utilizes the lathe right side is again processed semicircle cambered surface φ 1, the φ 2 of swash plate support right-hand member; After machining, only need to unscrew round nut 6, take out opening pressing plate 7; The swash plate support is changed, accomplished the loading and unloading task of workpiece.The processing back is measured, and both sides circular arc symmetry is no more than 0.05mm, and the arc surface profile tolerance is lower than 0.02mm, and the perpendicularity of two circular arcs and end face has fully improved machining accuracy less than 0.015mm, makes product quality be able to guarantee.
The above is merely the preferred embodiment of the utility model, and non-in order to limit the claim of the utility model, the equivalence of the patent spirit of other utilization the utility model changes, and all should all belong to the claim of the utility model.
