Description
Technical field
The invention belongs to mattress processing technique fields, more particularly, to a kind of equipment for spring production and processing.
Background technology
Sping mattress is very universal in bed accessory field, is twined by steel wire by multiple wind springs to knot up and down
Spring is gone here and there around rear formation, then after forming rectangular array by string spring, forms the spring bed core of mattress.Wherein, wind spring usually passes through wind spring
Multiple stations such as machine manufactures to obtain, and traditional spring coiling machine generally includes wind spring, knots, fires up and down, are rotated by turntable and are driven
Mechanical arm is moved to different location, and workpiece is driven to be moved between different station.But the brachium of mechanical arm in existing spring coiling machine
It can not be adjusted, and then when mechanical arm is in processing there are when mismachining tolerance, will be unable to be applicable in a device, mechanical arm is processed
Scrappage is high, high processing costs.Secondly, if assembly when there is rigging error, cause assembly after mechanical arm brachium it is too small or
It is excessive, it needs after dismantling entire mechanical arm, then reinstalled, operation is time-consuming and laborious.
Invention content
The present invention for overcome the deficiencies in the prior art, it is length-adjustable for spring production and processing to provide a kind of mechanical arm
Equipment.
To achieve the goals above, the present invention uses following technical scheme：A kind of equipment for spring production and processing, packet
Include central turnplate, wind spring station, upper knotting station, lower knotting station, heat treatment station and discharging station；The central turnplate packet
Include disk body, multiple mechanical arms on disk body, with the matched elastic flexible component of mechanical arm and for driving the disk body to turn
Dynamic actuator；The mechanical arm includes pedestal, the detachable body of rod being set on pedestal, the folder for being movably set in the body of rod top
Part and it is sheathed on that the body of rod is outer and the matched connector of elastic telescopic part；The connector is floating by elasticity with the folder
Moving part is connected；The body of rod includes first body of rod, is movably set in outside first body of rod second body of rod and for position this
One, the locking structure of the relative position between second body of rod.Relative displacement can occur in the present invention between first, second body of rod,
And then realize that the length of mechanical arm is adjustable, machinery can be passed through even if processing if there are errors or installation there are when error by realizing
The length adjustment of arm itself directly makes up existing error, and mechanical arm scrappage is low, without re-starting disassembling operations, works
It is efficient；Locking structure can carry out the position between first, second body of rod effectively to fix, and ensure in course of normal operation, the
One, between second body of rod be not in position movement；Mechanical arm is connected by elastic telescopic part with disk body, so that mechanical arm
A degree of floating can occur compared to the circumferencial direction of disk body to swing；Secondly folder passes through elastic floating part and connector phase
Even, to folder can on the length direction of the body of rod radial floating；When mechanical arm and station part are hit, mechanical arm exists
Mobile floating can be generated on front-rear direction, left and right directions, to effectively prevent the appearance of hardness shock, mechanical arm is not
It is fragile；Meanwhile floating is generated by elastic telescopic part, elastic floating part, the two all has after generating deformation replys
Power, to ensure mechanical arm after shock, can automatically reset back original state, ensure that workpiece is moved to when being processed on station
Position be not in deviation, ensure machining accuracy, the qualification rate of workpiece will not be impacted.
Further, the locking structure include be set to first body of rod in shrapnel, the positioning column on shrapnel,
The first trepanning that the positioning column is pierced by and be pierced by for the positioning column on second body of rod second is supplied on first body of rod
Trepanning；Pass through the setting of shrapnel so that positioning column can carry out scaling operation with respect to the first, second trepanning, and then press positioning column
So that in positioning column retraction to first body of rod, you can adjust the relative position between first, second body of rod, easy to operate, work
It is efficient.
Further, the positioning column is an integral molding structure with the shrapnel；It is easy to process, and be hardly damaged.
Further, second body of rod is equipped with the positioning element being defined for the position to positioning column；Pass through
Positioning column is limited on the position for being pierced by second body of rod by positioning element, ensures mechanical arm in the case where height rotates, positioning
Column will not be retracted in first body of rod, avoid the length of mechanical arm in process from changing, failure rate is low.
Further, the positioning element includes the operating lever being bolted on second body of rod and determines with what the operating lever was connected
Position block, the locating piece are placed in first body of rod, which can be inconsistent with the shrapnel；It is by turn operating lever
Locating piece can be driven to move, it is when needing to adjust the position between first, second body of rod, turn operating lever is separate to locating piece
The position of shrapnel；When needing to lock the position of first, second body of rod, turn operating lever to locating piece is contradicted to the position of shrapnel
It sets, ensures that shrapnel can not move backward, and then ensure that positioning column will not be retracted in first body of rod.
Further, the folder is equipped with the matched gripping slot of workpiece and scalable action to coordinate unlatching or pass
Close the elastic disconnecting prevention structure of the gripping slot；By the setting of elastic disconnecting prevention structure, effectively prevent workpiece the centrifugal force being subject to compared with
When big or mechanical arm is by larger shock, for workpiece by deviating from gripping slot, equipment failure rate is low；And flexible setting, make
Workpiece is obtained after completing to process, is still able to easily be pulled out out of gripping slot, feeding is easy to operate.
Further, the gripping slot includes positioned at the arc groove of folder upper surface central part and set on arc groove or so two
Two inclined-planes being connected with the arc groove on side；The elasticity disconnecting prevention structure includes symmetrical two groups be set on the folder
One group of retaining member is respectively arranged on two inclined-plane in retaining member.
In conclusion the present invention has the following advantages：Machine mechanical arm can directly be made up by the length adjustment of itself and be deposited
Error, mechanical arm scrappage is low, and without re-starting disassembling operations, work efficiency is high；Locking structure can avoid first, the
There is position movement in normal operation in bipole body；Mechanical arm can generate movement on front-rear direction, left and right directions
Floating, to effectively prevent the appearance of hardness shock, mechanical arm is hardly damaged；And mechanical arm can oneself after shock
It is dynamic to reset back original state, ensure that the position that workpiece is moved to when being processed on station is not in deviation, ensures machining accuracy, no
The qualification rate of workpiece can be impacted.
