Description
Technical field
The utility model belongs to Machining Technology, mainly proposes a kind of hub bearing overcoat cold roll spare turning end face anchor clamps.
Background technology
The processing that the turning of automobile hub bearing overcoat is shaped mainly contains two kinds of processing technologys, and the processing technology that turning is shaped is: forging stock → car internal diameter end face (smooth end as the location datum level) → car external diameter end face → buffing Double End → buffing external diameter → rounding → ditching (the ditch position measures from datum end face).The processing technology that cold roll shapes is: base before forging stock → car system is rolled over → cold roll is shaped.The overcoat end face that cold roll is shaped is rough and uneven in surface after spreading, jagged, reach the processing technology requirement, and end face must be in the roll milling forming post processing, so it is different from the turning forming technology, and workpiece end face can not be as machining benchmark.Adopting which kind of mode clamping work pieces processing end face to satisfy the requirement of hub bearing overcoat processing technology, is the problem that cold roll technology must solve.
Summary of the invention
The purpose of this utility model promptly is to propose a kind of hub bearing overcoat cold roll spare turning end face anchor clamps, satisfies the processing technology requirement of hub bearing overcoat cold roll spare turning end face.
The technical pattern of anchor clamps that the utility model proposes is: it mainly is made of clamping fixture seat, pull bar and fixed bearing, moving supporting; Clamping fixture seat is connected on the machining tool by flange, and a plurality of fixed bearings and moving supporting are divided into that two row are arranged on the anchor clamps pedestal and along the circumference uniform distribution of clamping fixture seat pedestal, fixed bearing, moving supporting be obliquely installed promptly and the clamping fixture seat axis between angle＜90 °; Circumferential fixed bearing, moving supporting are corresponding with the twice raceway groove of bearing outside respectively, with the twice raceway groove as the location benchmark; By supporting fixedly the twice raceway groove with the bearing outside fixed bearing; Its fixed bearing is the bulb pin, and its moving supporting is made of mobile pin, back-moving spring and steel ball, and cavity, the steel ball that its back-moving spring is positioned at mobile pin is fixed on the R nest of mobile pin one end; And be provided with mobile pin is stopped spacing spacing pin; Clamping fixture seat has in central shaft hole and the axis hole and has pull bar, and pull bar is connected by the piston rod of connecting rod with the machining tool oil cylinder.
The utility model anchor clamps are to the explanation of piece-holder process: anchor clamps are installed on the bearing process equipment, according to two raceway grooves of work piece with high-precision mould roll milling forming, its geometric accuracy can be used as the location benchmark (during the Che Yiduan end face fully, with the opposite side raceway groove of workpiece to be machined as benchmark, vice versa), the processing request when satisfying the turning end face.Clamping fixture seat is connected on the lathe spindle ring flange by connector, and pull bar is connected by the piston rod of connecting rod with the lathe oil cylinder.When initial, the piston rod of oil cylinder stretches out, and the moving effect that is bearing in the compression spring bounces back down, terminates in spacing pin place.During work, work piece is packed on the clamping fixture seat, one end raceway groove is affixed on the fixed supported bulb, oil cylinder piston bar retraction, pull bar is moved to left, and the uniform moving supporting of a plurality of inclinations (mobile pin is protruding, compression spring be fixed pin spacing back compression) contacts afterwards protruding with the outer surface of cone of pull bar, the promotion work piece moves to left, and finishes the clamping to workpiece.
The utility model jig Design is scientific and reasonable, and clamping workpiece is simple to operation, has guaranteed the supporting accurate positioning of workpiece and the production efficiency of processing.
