A kind of automatic leading mechanism on bushing press
The present invention relates to the automatic leading mechanism in the technical field of pressing machine, more particularly to a kind of bushing press.
Bushing is the ring set as pad effect, and it is mainly used in the field of valve, and it is generally fitted on bonnet,
So as to protect the valve rod through bonnet, there is good sealing effectiveness.From in dynamic pressure lining mechanism, product passes through supplied materials flowing water
Line reaches specified location, and automatic feed mechanism is shifted by clamping jaw cylinder clamping product, rotary cylinder rotation, stepper motor
Product is displaced on product displacement detent mechanism by action, and product is displaced to by product displacement detent mechanism by shifting and positioning
On positioning carrier, then bushing is discharged by vibrating disc, on the cylinder connector that the pressure lining mechanism above it passes through lift cylinder
The magnet of installation adsorbs to bushing, and is pressed on the both ends of product, should be from dynamic pressure lining mechanism and product flowing water
Line operation is engaged, and effectively realizes unmanned operation.But it is in the prior art, design from the cylinder connector in dynamic pressure lining mechanism
It is integrated, is connected directly between on pressing plate, when cylinder action, certain angle deviation when its piston rod pushes often is present, holds
Stuck situation easily occurs.
Chinese invention patent 201310106190.0 discloses a kind of cylinder connector, including one is connected with cylinder motion bar
The top connection connect and a lower contact being connected with using device, the lower end of the top connection is disposed with circle from top to bottom
Trunk portion and round boss, narrow slot and sipes, the circle of top connection are offered successively from top to bottom in the upper surface of the lower contact
Trunk portion is arranged in narrow slot, and the round boss of top connection is arranged in sipes, and the diameter in the cylinder portion is less than narrow slot
Width, the diameter of the round boss are less than the width of sipes and are adapted to more than the width of narrow slot, the cylinder connector special
Occasion uses, and can compensate cylinder automatically and using the coaxiality deviation between device, and compensation range is larger.It is but anti-according to applicant
Reflect, the cylinder connector in use, although can realize to cylinder and be mended using the coaxiality deviation between device
Repay, but still come with some shortcomings：The round boss of the top connection of the cylinder connector is arranged in the sipes of lower contact, its circumferential edge
Contacted between sipes for arc, to realize automatic compensation cylinder and use the coaxiality deviation between device, and round boss
End face and lower contact sipes between be plane contact, due between the two to answer power cooperation, under cylinder drive cylinder joint
It during pressure, can still be misplaced between top connection and lower contact, when causing the lower contact to push vertically, certain angle deviation, meeting be present
Appearance bush press-fit position is inaccurate, bears the problem of pressure is small, and percent defective is high, reduces production efficiency.
The content of the invention
The purpose of the present invention is in view of the deficiencies of the prior art, there is provided the automatic guiding on a kind of bushing press
Mechanism, cylinder connector use separation design, by the arc surface fit system between top connection and lower contact, to pushing vertically
When all around the deviation in direction and axiality direction compensate, realize automatic guiding, and combine X-axis governor motion and Y-axis
Governor motion, ensure the positional precision pushed, improve pressure head and bear pressure.
The technology solution of the present invention is as follows：
A kind of automatic leading mechanism on bushing press, it is characterised in that：Including cylinder connector, cylinder contiguous block and
Pressure head, the cylinder contiguous block are symmetrically positioned in the both sides of cylinder connector, and cylinder contiguous block is sequentially provided with narrow slot and width from top to bottom
Groove；The cylinder connector includes top connection and lower contact, and its top connection is fixedly connected with the piston rod of cylinder, and lower contact is set
On cylinder contiguous block, the top connection is sequentially provided with cylinder portion and circular arc boss, the upper surface processing of lower contact from top to bottom
Go out the arc groove to match with the circular arc boss, the cylinder portion of top connection is placed in narrow slot, and lower contact is placed in sipes；
The pressure head is fixedly connected with lower contact and is provided with electromagnet positioned at the lower section of cylinder contiguous block, the pressure head.
As an improvement, it is coaxially disposed between the top connection, lower contact and pressure head.
As an improvement, the narrow slot is coaxially disposed with sipes, the diameter of sipes is more than the diameter of narrow slot.
As an improvement, symmetrically offering two necks in the side wall in the cylinder portion, being equipped with one in each neck stops
Switch block, the anti-rotation block are arranged on cylinder contiguous block, for preventing the piston rod rotation of cylinder.
As an improvement, also including X-axis governor motion and Y-axis governor motion, the X-axis governor motion includes X-axis regulation spiral shell
Nail seat and X-axis regulating block, X-axis adjusting screw seat and X-axis regulating block are connected by X-axis adjusting screw；The Y-axis governor motion
Y-axis adjusting screw seat and Y-axis regulating block including being installed on cylinder contiguous block bottom, Y-axis adjusting screw seat and Y-axis regulating block lead to
Y-axis adjusting screw is crossed to be connected.
As an improvement, the X-axis adjusting screw seat and X-axis regulating block are arranged on Y-axis regulating block, X-axis regulating block and Y
Axle regulating block is sheathed on the pressure head.
As an improvement, the X-axis adjusting screw seat is vertically arranged with Y-axis adjusting screw seat.
The beneficial effects of the present invention are：
(1) present invention uses the cylinder connector of separation design, and it is inclined that certain angle is produced when the piston rod of cylinder pushes
In the case of difference, by the arc surface being engaged between the top connection and lower contact of cylinder connector, can to direction all around with
And the deviation in axiality direction is compensated automatically, realizes automatic guiding, ensure the positional precision pushed, meanwhile, top connection and
Contact area is big between arc surface in lower contact, increases it and bears pressure, avoids lower contact because left and right directions generation deviation is larger,
Make the inaccurate even lower contact in pressing position of bushing that the problem of stuck occur；
(2) X-axis governor motion and Y-axis governor motion are mounted on the bottom of cylinder contiguous block, and X-axis governor motion is arranged on
On Y-axis governor motion, corresponding X-axis regulating block and Y-axis regulating block are adjusted by X-axis adjusting screw and Y-axis adjusting screw respectively
Position, and then adjust position of the pressure head in X-axis or Y direction, it is ensured that the position of pressure head pressing bushing is accurate, improves product
In summary, the present invention has simple in construction, is easily installed, and requirement on machining accuracy is low, the advantages that automatic guiding.
