In process of production, have the elongated rod member type component of many kinds to need welding, for example rod member of the parts such as rod assembly on the automobile and one or both joints are welded as a whole, and the shape of weld seam mostly is the shape of a saddle or annular.If the welding of these parts does not have the frock clamp location, just be difficult to guarantee requirements such as relevant fitted position, welding quality and mass production.For rod member type component revolution welding tooling, realize that rod member supports, Centering Clamping fast, make rod member sentence level or vertical state, be vital with the needs that satisfy the workpiece welding procedure.
At present, in Centering Clamping class mechanism design, centre frame, triangle chuck, turning rolls or special-purpose centralized positioning locking device.Centre frame is used for the turning or the grinding aspect of thin and long shafts workpiece more, needs artificial three strong point centerings of adjusting, and efficient is low.The triangle chuck is used for the turning aspect of shaft-like workpiece more, also is used for the welder of shaft-like workpiece, needs manual locking usually, also can change a social system to modes such as pneumatic, electronic, hydraulic pressure and lock, but integral body is an enclosed construction, and the clamping of inconvenient workpiece picks and places, particularly elongated class rod member.Turning rolls is used for big or large cylindrical shape workpiece more, is not suitable for elongated rod member class workpiece.Special-purpose centralized positioning locking device is applicable to a certain concrete workpiece, and versatility is poor.
The utility model content
The problem of carrying out automatic Centering Clamping when solving rod member class part welding processing, the utility model provides a kind of pneumatic pinch centring means.This device has been realized 3 interlocks, the automatic Centering Clamping of open loop type, with the rod member type component of different-diameter reliably Centering Clamping on the same centre of gyration.
For achieving the above object, the technical solution of the utility model is: this device mainly is made up of pin and screw that Centering Clamping Component, arc drive block, guide-localization assembly, holder, cylinder (also drive units such as motor, hydraulic pump) and some are connected and fixed usefulness, wherein Centering Clamping Component is made up of pin and screw that Centering Clamping bar, bearing and some are connected and fixed usefulness, and the guide-localization assembly is made up of pin and screw that guide securement bar, bearing and some are connected and fixed usefulness.The arc drive block is connected with holder by the guide-localization assembly, is fixed with three bearings on it, is used to drive Centering Clamping Component; Respectively be processed with an arc concentric grooves inside and outside the arc drive block, inside and outside groove respectively has two guide-localization assembly positioning and guidings, and the guide-localization assembly is separately fixed on the holder, has constituted the arc slew gear; The arc drive block is by guide-localization assembly positioning and guiding.Three Centering Clamping Components and holder are hinged, are processed with groove on part Centering Clamping bar under it, and three fixing on arc drive block bearings are assemblied in respectively in the groove of three Centering Clamping bars, and bearing can freely roll in groove, move up and down; The groove of the affiliated part Centering Clamping bar of Centering Clamping Component adds sliding block type structure with the arc drive block with hinge and is connected, and the other end is equipped with the Centering Clamping part.Drive the arc drive block, it can do gyration around its center of circle at the guide-localization inter-module, and drive three interlocks of Centering Clamping Component, realize the automatic Centering Clamping of open loop type, with the rod member type component of different-diameter reliably Centering Clamping on the same centre of gyration.The holder bottom is equipped with alignment pin and some screwed holes that is used to install, and is convenient to be connected with different devices, constitutes automatic complete set of equipments.
The utility model adopts the open loop type structure of three rod members interlocks, quickly and easily to the rod member type component of different-diameter reliably Centering Clamping on the same centre of gyration; The utility model is except that pneumatic, and also being fit to adopt motor, Hydraulic Station is that Power Drive Unit constitutes automatic control equipment.The utility model is simple in structure, and adaptability is strong, and low cost of manufacture is very practical, and very high application and popularization value is arranged.
