Abstract

The invention relates to an automatic clamping and centering method and an automatic clamping and centering device. A sliding block set taking an arc sliding block mechanism as a center and clamping and centering assemblies form a three-bar linkage open structure, and three-point linkage is performed by drive of a power module so as to automatically clamp and center rods of different diameters on the same rotary center. The device mainly comprises the power module, a transmission module, three clamping and centering assemblies and a fixed seat. The transmission module is the arc sliding block mechanism consisting of an arc driving block serving as a main body, certain guiding and positioning assemblies and rolling elements; and the three clamping and centering assemblies and the transmission module form a three-bar linkage sliding block set through the rolling elements. The power module can drive the transmission module by adopting a pneumatic, electric or hydraulic power source so that the arc sliding block mechanism rotates around the circle center of the power module and drives the linkage of the three clamping and centering assemblies to realize open automatic clamping and centering. The device has a simple structure and strong practicability, and has higher application and popularization values.

The present invention relates to a kind of method and device of automatic Centering Clamping, be meant a kind of method and device that rod member class part carries out automatic Centering Clamping that be used for especially.
Background technology
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 the box-like structure of a sealing, 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.
Summary of the invention
The problem of carrying out automatic Centering Clamping when solving rod member class part welding processing the invention provides a kind of method and device of automatic Centering Clamping.It is the slide block at center that the present invention adopts with arc shaped slider mechanism, constitutes the open architecture that three rod members link with Centering Clamping Component, carries out 3 interlocks with the power plant module drive source, realizes the automatic Centering Clamping of the rod member of different-diameter on the same centre of gyration.
For achieving the above object, technical scheme of the present invention is: this device mainly is made up of power plant module, transmission module, three Centering Clamping Components and holder.Transmission module is the arc shaped slider mechanism based on an arc drive block.Be fixed with three rolling members on the arc drive block, be used to drive the Centering Clamping module; 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; The guide-localization assembly is made up of pin and screw that guide securement bar, rolling member and some are connected and fixed usefulness, and the guide-localization assembly is separately fixed on the holder; Arc drive block and guide-localization assembly etc. constitute an arc shaped slider mechanism, can do gyration around its center of circle.Centering Clamping Component is made up of pin and screw that Centering Clamping bar, rolling member and some are connected and fixed usefulness; Three Centering Clamping Components and holder are hinged, be processed with groove on the part Centering Clamping bar under it, three fixing on arc drive block rolling members are assemblied in respectively in the groove of three Centering Clamping bars, and rolling member can freely roll in groove, move up and down.Power plant module can adopt drive power source transmission modules such as cylinder, motor or hydraulic pressure, makes arc shaped slider mechanism do gyration around its center of circle, and drives three interlocks of Centering Clamping Component, realizes the automatic Centering Clamping of open type.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 present invention adopts the open architecture of three bars interlocks, can be quickly and easily to the automatic Centering Clamping of rod member type component of different-diameter on the same centre of gyration.The present invention is fit to adopt Power Drive Units such as cylinder, motor, Hydraulic Station to constitute automatic control equipment.The present invention is simple in structure, and low cost of manufacture is practical, and very high application and popularization value is arranged.
