Description

The anchor clamps that are used for double-head piston ball pit processing
Technical field
The present invention relates to a kind of anchor clamps positioner, especially a kind of anchor clamps that are used for double-head piston ball pit processing.
Background technology
The anchor clamps that are used for double-head piston ball pit processing at present still adopt traditional anchor clamps, and the anchor clamps of this quasi-tradition mainly comprise screw mandrel and locating piece, and locating piece and screw mandrel are through being threaded; Locating piece can be done to move around through the rotation of screw mandrel, thus intact existing locking positioning to workpiece, because the idiosome that is used to process is mostly for cylindrical; On this type of conventional brace, it radially all can only be accomplished through axial clamping with axial location, and locating effect is relatively poor; The idiosome work in-process is easy to generate slight loosening; Because double-head piston ball pit need be through repeatedly processing repeatedly, higher to requirement on machining accuracy, becoming flexible that idiosome is small just possibly influence product quality; And,, clamp deleterious when the stressed revolution that can cause screw mandrel when excessive of workpiece because screw mandrel self does not have locking function, thus cause that idiosome is loosening, be easy to damage idiosome man-hour adding, this has brought inconvenience for processing of double-head piston ball pit.
Summary of the invention
The objective of the invention is to provide for the deficiency that solves above-mentioned technology a kind of radially with axially all have clamp function, accurate positioning is difficult for the loosening anchor clamps that are used for double-head piston ball pit processing.
In order to achieve the above object, the anchor clamps that are used for double-head piston ball pit processing that the present invention designed, it mainly comprises base plate; Base plate is provided with locating piece and holds out against pole socket, can place the idiosome that is used for double-head piston ball pit processing on the locating piece, holds out against and is provided with the top-fastening rod that cooperates the location with locating piece in the pole socket; Described top-fastening rod side is provided with telescopic clamping rod; This clamping rod and first hydraulic jack are in transmission connection, and also are provided with on the said base plate and compress arm seat, compress arm seat and are provided with clamping arm; Clamping arm is installed in through hinge arrangement and compresses on the arm seat, and said clamping arm one end is positioned at the locating piece top and cooperates clamping with locating piece.Clamping rod can play good locking action to top-fastening rod; After top-fastening rod holds out against the completion of workpiece location, can make it fix top-fastening rod through the operation clamping rod, thereby can prevent top-fastening rod generation rollback phenomenon; Make that the axial location of workpiece is more firmly accurate; Through being used of clamping arm and locating piece, can play the good effect that is fixed to workpiece diametrically in addition, prevent to become flexible; In order to realize good automatic work, the described clamping arm other end is connected with telescopic push rod through hinge arrangement, and this push rod and second hydraulic jack are in transmission connection.Hydraulic jack is easy to operate, and enough big push-tight power can be provided.Can be that described push rod vertically is provided with, second hydraulic jack be in transmission connection through a horizontally disposed connecting rod and push rod.
In order to realize better clamping and positioning, can be provided with " V " shape groove on the described said locating piece, the part of said clamping arm above locating piece comprise one fall " V " shape groove chuck." V " shape groove can play advantages of good positioning effect, and especially for some cylindrical workpieces, locating effect is better.In order to cooperate the twitch up and down of push rod, said clamping arm two ends can upwarp, and its hinge arrangement junction can be recessed, form " √ " shape substantially.
In order to realize better clamping and positioning, can be provided with circular trough on the said locating piece, the part of said clamping arm above locating piece comprises the chuck of a semi-circular groove.
In order to play the good effect that compresses at ordinary times, the described pole socket that holds out against is provided with handle, and handle stretches into to hold out against in the pole socket and with said top-fastening rod and is connected, and handle is outer to be provided with spring base, is provided with the compression spring between this spring base and the top-fastening rod.The compression spring can produce pressure to top-fastening rod, especially when clamping rod is flexible, can guarantee the invariant position of top-fastening rod.
The resulting anchor clamps that are used for double-head piston ball pit processing of the present invention can make it fix top-fastening rod through the operation clamping rod, thereby can prevent top-fastening rod generation rollback phenomenon, make that the axial location of workpiece is more firmly accurate; Through being used of clamping arm and locating piece, can play the good effect that is fixed to workpiece diametrically, prevent to become flexible, make workpiece radial location more firmly accurately, reduce greatly adding the probability of damaging workpiece man-hour, crudy is better.
