On be provided with hydraulic pressure top；The main pressed seat and two secondary pressed seats are located at the both sides of positioning seat respectively, are set on secondary pressed seat
It is equipped with hydraulic push rod, fixed block and Z-shaped pressure arm；One end of the lower part of the Z-shaped pressure arm is hinged with hydraulic push rod, and the other end passes through
Connecting plate is connected with fixed block, and the both ends of connecting plate are hinged with fixed block and Z-shaped pressure arm respectively, the end on the top of Z-shaped pressure arm
It is provided with compact heap.
Preferably, the horizontal clamping assembly has two groups, and two groups of horizontal clamping assemblies are symmetrically set in the both sides of main pressed seat
Put, the main pressure arm on main pressed seat is double end pressure arm, and the middle part of main pressure arm and the flexible bar portion of main pressed seat are hinged, main pressure arm
Both ends coordinate clamping workpiece with two groups of horizontal clamping assemblies respectively.
Preferably, vertical guide groove is provided with the clamping seats, the locking pin coordinated with guide groove is additionally provided with base.
Due to the utilization of above-mentioned technical proposal, the present invention has following advantages compared with prior art：
The reverse fixture of the knuckle of the present invention, by optimizing clamping component, improves the handling speed of knuckle workpiece, improves
Processing efficiency；Each clamping component fixes the agent structure of knuckle workpiece, ensure that the stability of clamping；And optimize
The integral layout of clamping component, makes overall basic holding weight balancing, ensure that machining accuracy.
Brief description of the drawings
Technical solution of the present invention is described further below in conjunction with the accompanying drawings：
Attached drawing 1 is a kind of stereogram of the reverse fixture of knuckle of the present invention；
Attached drawing 2 is the stereogram of secondary pressed seat of the present invention.
Embodiment
Illustrate the present invention below in conjunction with the accompanying drawings.
As shown in attached drawing 1-2, a kind of reverse fixture of knuckle of the present invention, comprising base 21, sets on base 21
Main pressed seat 22 and two groups of horizontal clamping assemblies for being symmetricly set on main 22 both sides of pressed seat are equipped with, horizontal clamping assembly includes fixed
Position seat 23, clamping seats 24 and two secondary pressed seats 25；Main pressure arm 26 is provided with the main pressed seat 22, main pressure arm 26 is double end
Pressure arm, the middle part of main pressure arm 26 and the flexible bar portion of main pressed seat 22 are hinged；Steering arm fixture block is provided with the clamping seats 24
