10 relatively rotate.Arc portion feed mechanism further includes top-pushing mechanism (not shown), and arc portion 7 is under the promotion of top-pushing mechanism
Arcuately elongated slot 10 is transported to arc portion positioning seat.Control module in place and location switch are also configured on arc portion feed mechanism
The setting position on arc portion feed mechanism is arranged in (not shown), location switch, sets when an arc portion 7 is transported to this
When positioning is set, location switch is triggered, signal is passed to control module in place by location switch, and control module controls arc immediately in place
Portion's feed mechanism stops working, and is welded with reserving time enough to for the arc portion 7 of welding, avoid subsequent arc portion with
The arc portion 7 welded is collided, and after arc portion completion welding is acted and taken out, control module continues to control arc portion feeding in place
Mechanism action carries out the feeding of next arc portion.
Location switch in the present embodiment is travel switch, and concrete model is LXK3 type travel switch.
Arc portion positioning seat is equipped with positioning pin 5 and locating piece, locating piece, that is, locating piece 8, and positioning pin 5 is driven by positioning pin
Mechanism, that is, hydraulic cylinder (not shown) driving, positioning pin 5 are arranged on the piston rod of hydraulic cylinder, pass through stretching for control piston rod
Contracting may be implemented the reciprocating movement of positioning pin 5, the positioning with arc portion 7 realized in the pluggable pin hole 701 to arc portion 7 of positioning pin 5
Cooperation, when piston rod stretch out when, positioning pin 5 be inserted into pin hole 701 in, after welding, piston rod retract, drive positioning pin 5 with
Pin hole 701 separates.Locating piece 8 is used to support location fit along the width direction perpendicular to arc portion 7 with arc portion 7, specifically, positioning
Block 8, which has be adapted to the intrados of arc portion 7, is bonded curved end to support arc portion 7, curved end increase locating piece 8 and
The contact area of the intrados of arc portion 7, support effect are more preferable.Block location structure, i.e. baffle 9 are additionally provided on arc portion positioning seat,
Baffle 9 can on the width extending direction of arc portion 7 to arc portion 7 carry out block limit, in this way, positioning pin 5, locating piece 8 and
Under the cooperation positioning support of baffle 9, shape that holding that the equal arc length straight line of arc portion 7 can be made stable and datum axis intersect vertically
State, the holding that width etc. divides camber line stable intersect at datum axis, namely make arc portion 7 by it is stable be located in one it is fixed
Posture is ready for welding.
Apparatus for welding and positioning further include pressure touching driving mechanism, pressure touching driving mechanism be used for arc portion 7 apply active force so that
Arc portion 7 and the relatively close pressure of axle portion 2 are touched, specifically, pressure touching driving mechanism includes arc portion driving mechanism and push rod, arc portion driving machine
Structure be resistance welder second electrode terminal, push rod be between second electrode terminal and locating piece 8 and with second electrode end
The telescopic rod of the cylinder of son connection, second electrode terminal and locating piece 8 be conductively connected and with 7 conductive communication of arc portion, along benchmark
Axis direction drives 8 reciprocating action of locating piece to drive arc portion 7 to act；Cylinder driving push rod under the driving of second electrode terminal
Apply active force to locating piece 8 to realize the movement of arc portion 7.It is pressed after touch when arc portion 7 is moved to axle portion 2, passes through resistance welder
Arc portion 7 and axle portion 2 can be welded, to form the agricultural machinery cross lever limiting bracket of one.
Since cooperation is to 7 positioning support of arc portion jointly for positioning pin 5 and locating piece 8 and baffle 9, in order to make positioning pin 5 exist
Arc portion 7 can still be limited in the moving process of arc portion 7, and relative motion, apparatus for welding and positioning not occur with locating piece 8
In be additionally provided with guiding mechanism, guiding mechanism can be oriented to positioning pin 5 to be cooperated so that positioning pin 5 follows arc portion 7 to act, and is sufficiently protected
Demonstrate,prove the stabilization of the posture of arc portion 7.Specifically, guiding mechanism includes cross rail and vertical guide rail, cross rail is arranged on the rack and edge
The block direction of baffle 9 extends, and is provided with sliding block on cross rail, and vertical guide rail is arranged on sliding block and edge is parallel to datum axis side
To extension, positioning pin 5 is oriented to slidable fit in indulging on guide rail, in this way, the guide rail of transverse and longitudinal cooperation makes the mobile route of positioning pin 5
Available more accurately to control, also more stable to position-limiting action of the arc portion 7 in moving process, locating effect is more preferable.
Welder further includes PLC controller (not shown), the small-sized editable of controller model Micro800
Logic controller, the control module in place of above-mentioned control axle portion feed mechanism, the control mould in place for controlling arc portion feed mechanism
Block belongs to a part of controller, and controller further includes the positioning control for controlling the pin hole location fit inserting of positioning pin and arc portion
Molding block, control arc portion driving structure, that is, second electrode terminal drive control module, in this way, each movement of axle portion and arc portion
It can timely be controlled by PLC controller, and be moved to pressure touching position accurately to be welded, it is fixed to improve welding
The uniformity of various pieces cooperation in the device of position.
When agricultural machinery cross lever limiting bracket welder of the present invention works, PLC controller issues instruction, the first control mould
Block and the second control module control axle portion feed mechanism 6 respectively and convey axle portion 2 and arc portion feed mechanism to arc to axle portion positioning seat 1
Portion's positioning seat conveys arc portion 7, and when a transport of axle portion 2 extremely will reach axle portion positioning seat 1, axle portion 2 is touched first to be opened in place
It closes, control module controls axle portion feed mechanism 6 after the signal for receiving location switch and stops working in place, enough to reserve
Time is welded for the axle portion 2 of welding, is collided to avoid subsequent axle portion 2 with the axle portion 2 welded, and the clamping of manipulator 11 should
Axle portion 2 is placed in the positioning straight trough 3 of axle portion positioning seat 1 and is fixed by gripping block, the first electrode terminal and machine of resistance welder
Tool hand 11 connects, and is ready for the welding of axle portion 2；On the other hand, an arc portion 7 after being transported to arc portion positioning seat, touch by arc portion 7
Dynamic location switch, the arc portion feed mechanism of control module control in place stops working, to reserve time enough for the arc portion 7 of welding
