Embodiment
It is described below for disclosing the utility model so that those skilled in the art can realize the utility model.Retouch below
Preferred embodiment in stating is only used as illustrating, it may occur to persons skilled in the art that other obvious modifications.
A kind of steel ball press-in device for valve body manufacture as shown in Figs. 1-5, including base 5, be fixed on base 5
Push rod 6, be set on push rod 6 and can be along the beam barrel 7 that its axis direction moves.
Specifically, the beam barrel 7 is provided with hollow cavity 73 on its axis, and the push rod 6 coordinates with hollow cavity 73
And move back and forth in hollow cavity 73.The beam barrel 7 away from push rod 6 fixing end one end periphery on be provided with
The steel ball entrance 71 that hollow cavity 73 connects, the cross-sectional sizes in the hole of the steel ball entrance 71 can only accommodate steel ball 100
Size.The section of the steel ball entrance 71 is preferably circular, and circular diameter is equal to or slightly greater than the diameter of steel ball 100.
Connection flexible pipe 72 at the steel ball entrance 71, the hose 72 are connected with the storeroom of steel ball 100 to constantly into beam barrel 7
Transporting steel balls.In order to ensure only have a steel ball 100 to be entered from steel ball entrance 71 in hollow cavity 73 every time, the hollow cavity
Diameter of the body 73 at steel ball entrance 71 is equal to or slightly greater than the diameter of steel ball 100.
The limiting slot 74 extended along its axis is provided with the beam barrel 7, is provided with push rod 6 and matches somebody with somebody with limiting slot 74
The spacer pin 61 of conjunction, can limit push rod 6 by the cooperation of spacer pin 61 and limiting slot 74 and beam barrel 7 moves within the specific limits
It is dynamic.In order to ensure that steel ball 100 can be pushed out, when beam barrel 7 and push rod 6 relatively move, the push rod 6 at least can be from
One end for being provided with steel ball entrance 71 of beam barrel 7 is stretched out so that steel ball 100 is ejected beam barrel 7, while the free end of push rod 6 can contract
The side of the fixing end of the close push rod 6 of steel ball entrance 71 is returned to so that steel ball 100 can be dropped into hollow cavity 73.Together
When, it is inserted into order to facilitate push rod 6 in beam barrel 7, the spacer pin 61 uses screw thread or other dismountable modes with push rod 6
Connection.
The spring (not shown) for being in compressive state all the time is provided with push rod 6 and between beam barrel 7 and base 5,
The spring has makes push rod 6 be in the trend of retracted mode relative to beam barrel 7 all the time, when pressing-in force eliminates, push rod 6 oneself
Steel ball entrance 71 is retracted into close to the side of the fixing end of push rod 7 by end.
The steel ball press-in device further includes driving structure, and the driving structure includes pedestal 1, is pivotally supported at base
Screw 51 on seat 1 and the pair of nut 58 with the cooperation of screw 51, the base 5 is fixedly connected with pair of nut 58, and push rod 6
Axis it is parallel with the axis of screw 51 and then beam barrel 7 can be driven to move back and forth along its axis.When in use, by valve body 101
Receiving port 102 be aligned beam barrel 7 (thering are other grip devices to be aligned) the port of export, then screw 51 rotate, drive base 5
Moved towards the direction of valve body 101, after the reception end in contact of the port of export and valve body 101 of beam barrel 7, screw 51 is rotated further,
Beam barrel 7 no longer moves at this time, and base 5 drives push rod 6 to continue the direction movement towards valve body 101, and push rod 6 pushes away steel ball 100
Enter to after the precalculated position in valve body 101, screw 51 inverts, after the receiving terminal 102 of beam barrel 7 and valve body 101 departs from, in bullet
Under the action of spring, push rod 6 is set to be retracted into original position, next steel ball 100 is entered in hollow cavity 73.
In order to ensure stability of the base 5 in moving process, two are provided with pedestal 1 and parallel with screw 51 is led
Rail 57, is provided with two sliding blocks coordinated with guide rail 57 on base 5.
In order to ensure that beam barrel 7 can exactly in place during relative movement with push rod 6, the corresponding limit on beam barrel 7
The position in place extended and retracted of position pin 61 sets position sensor (not shown), when the position sensor of respective side detects
To spacer pin in place when screw no longer rotate or rotated towards opposite direction.
In order to enable steel ball 100 steel ball entrance 71 can be arranged to court automatically into hollow cavity 73
Upward or at least towards inclined upward, can so be entered by gravity in hollow cavity 73.
Larger power is needed due to being pressed into steel ball 100 in the receiving terminal 102 of valve body 101, is all collected when by all power
In when on fixture, the relative position of the position or valve body 101 of fixture on fixture can be made to change, in order to reduce fixture
Etc. the active force suffered by equipment, on pedestal 1 and with the port of export of beam barrel 7 relative to fixed seat 53, when in use, valve body
101 are moved to fixed seat 53 close to the side of base 5 and are resisted against in fixed seat 53, in this way, when steel ball 100 is pressed into, press-in
Power is just largely focused in fixed seat 3, and the equipment such as fixture only needs to keep the position of valve body 101.
The driving structure further includes the servomotor 56 being connected with leading screw 51, between the servomotor 56 and screw 51
It is provided with retarder 55.
