Description
Technical field
The utility model relates to machine industry, specially a kind of hydraulic centralizing mechanism.
Background technique
Currently, the positive/negative thread centering that the centering of part mainly uses in machine-building, the structure is by screw thread process essence
The influence of degree causes centered positions inaccurate, influences the machining accuracy of part it cannot be guaranteed that two sides are fully synchronized；Meanwhile by spiral shell
The limitation of line spiral shell square, the centering time is long, influences processing efficiency.
Summary of the invention
The purpose of the utility model is to provide a kind of structures simply, convenient for operation, high-efficient hydraulic centralizing mechanism, the machine
Structure can guarantee that synchronous progress is held in the centering of two side cylinders tightly, improve the accuracy of centering.
A kind of the technical solution of the utility model are as follows: hydraulic centralizing mechanism comprising left oil cylinder, left centering piece, left pin shaft,
Left connecting rod, left straight pin, turntable, right straight pin, right connecting rod, right pin shaft, right centering piece, right oil cylinder, pedestal, left oil cylinder are fixed on
Chassis left side, left centering piece are placed in base rail, and left oil cylinder is mounted in left centering piece piston hole, and left centering piece passes through left pin
Axis is connected with left connecting rod, and right oil cylinder is fixed on base right side, and right centering piece is placed in base rail, and right oil cylinder is mounted on right centering
In part piston hole, right centering piece is connected by right pin shaft with right connecting rod, and left connecting rod and right connecting rod pass through left straight pin and right cylinder
Pin is connect with turntable, and turntable is mounted in the location hole of pedestal.
The left connecting rod and right connecting rod is connect by left straight pin and right straight pin with turntable, is machined on turntable symmetrical
Two straight pin location holes, left and right connecting rods two center carpenters square cun is identical.
The advantages of the utility model is as follows: after the oil cylinder oil inlet of left and right, left connecting rod and right connecting rod pass through turntable and mutually restrain work
With realizing the synchronous operation of centering.It is simple and reliable for structure, it is high-efficient, at low cost convenient for operation.
Detailed description of the invention
The present invention will be further described with example with reference to the accompanying drawing.
Fig. 1 is the structure chart of utility model.
Fig. 2 is the cross-sectional view of Fig. 1.
Specific embodiment
As depicted in figs. 1 and 2, a kind of hydraulic centralizing mechanism, specifically includes: left oil cylinder 1, left centering piece 2, left pin shaft 3, a left side
Connecting rod 4, left straight pin 5, turntable 6, right straight pin 7, right connecting rod 8, right pin shaft 9, right centering piece 10, right oil cylinder 11, pedestal 12, it is left
Oil cylinder 1 is fixed on 12 left side of pedestal, and left centering piece 2 is placed in 12 guide rail of pedestal, and left oil cylinder 1 is mounted on left 2 piston hole of centering piece
In, left centering piece 2 is connected by left pin shaft 3 with left connecting rod 4, and right oil cylinder 11 is fixed on 12 right side of pedestal, and right centering piece 10 is placed in
In 12 guide rail of pedestal, right oil cylinder 11 is mounted in right 10 piston hole of centering piece, and right centering piece 10 passes through right pin shaft 9 and right connecting rod
8 are connected, and left connecting rod 4 and right connecting rod 8 are connect by left straight pin 5 and right straight pin 7 with turntable 6, and turntable 6 is mounted on pedestal 12
Location hole in.The left connecting rod 4 and right connecting rod 8 is connect by left straight pin 5 and right straight pin 7 with turntable 6, on turntable 6
Symmetrical two straight pin location holes are machined with to connect with left straight pin 5 and right straight pin 7；The left connecting rod 4 and right connecting rod 8
It is connect by left straight pin 5 and right straight pin 7 with turntable 6, left connecting rod 4 is identical as right connecting rod 8 liang of center carpenters squares cun.
Concrete operating principle: left 1 oil inlet and oil return of oil cylinder drives left 2 forward-reverse of centering piece, while 11 oil inlet and oil return band of right oil cylinder
It moves right 10 forward-reverse of centering piece, since the effect of left pin shaft 3 drives left connecting rod 4 to rotate when left 2 forward-reverse of centering piece, pushes
Turntable 6 is rotated around the location hole of pedestal 12, meanwhile, when right 10 forward-reverse of centering piece due to the effect of right pin shaft 9 drive it is right
Connecting rod 8 rotates, and pushes turntable 6 to rotate around the location hole of pedestal 12, realizes the self-centering and release of workpiece.
