Description
Technical field
The present invention relates to press equipment fields, and in particular to ball head connecting rod tooling.
Background technology
The rotary motion of motor is generally converted to the straight reciprocating motion of sliding block by forcing press by slider-crank mechanism,
Blank is formed the metal forming machinery of processing.Thus many forcing presses by ball head connecting rod come interlink electric machine and sliding block, shape
At slider-crank mechanism.But many large-scale forcing presses need to dismantle sliding block from forcing press since weight, volume are excessive
Get off separated transport.The ball head connecting rod being assemblied at this time on sliding block can be rotated arbitrarily, carried in sliding block and held in long distance transportation
The fracture of bulb pin is easily caused, the damages such as upper ball bowl dislocation cause very big puzzlement to transport and installation.
Therefore, a kind of tooling of ball head connecting rod how is designed, so that it is overcome the problems, such as above-mentioned, is people in the art
Member's problem urgently to be resolved hurrily.
Invention content
The main purpose of the present invention is to provide a kind of fixed ball head connecting rods, and adapt to different size ball in a certain range
The press ball connecting rod carrying tooling of head connecting rod.
To achieve the above objectives, the technical solution adopted by the present invention is：A kind of press ball connecting rod carrying tooling, it is special
Sign is：Be relatively arranged on tooling unit including two, each tooling unit include fixed plate, movable plate, propulsion assembly,
Circumferential limit assembly and axial limiting component；
The fixed plate is fixedly installed on slide body, and the propulsion assembly is set to the fixed plate and the movable plate
Between, for pushing the movable plate closer or far from ball head connecting rod, and then the tooling unit is made to close up or separate；
The circumferential direction limit assembly includes semicircular planform, half smooth block and elastica, and the semicircular planform is fixedly installed on
On the movable plate, half smooth block is circumferentially slideably positioned on the semicircular planform and can fix at an arbitrary position, institute
The lower binding post for being provided on semicircular planform and along the circumferential direction arranging is stated, is provided on half smooth block and along the circumferential direction arranges
Upper binding post, the lower binding post and upper binding post is concentric and not isometrical setting, the elastica both ends are fixed respectively
It is set on the corresponding lower binding post and the upper binding post；When two tooling unit alignments are closed up, the institute of both sides
It states semicircular planform to merge to form circular platform, the semicircle sliding block of both sides merges to form round slider, and the round slider exists
It is rotated on the circular platform, makes the elastica that circumference dislocation motion occur, iris diaphragm structure is formed, for limiting the bulb
Movement of the connecting rod in circumferential plane；
The axial limiting component includes upright bar, handle, locking arm and spring, and the upright bar is fixedly installed on the movement
On plate, the handle is rotatably dispose in the upright bar, and the locking arm is fixedly installed on the handle, the spring setting
Between the upright bar and the handle, force the handle and the locking arm close to the ball head connecting rod；Two works
When dress unit alignment is closed up, the locking arm of both sides clamps the ball head connecting rod, and in conjunction with the locking arm and the bulb
Frictional force between connecting rod limits the axial movement of the ball head connecting rod and circumferentially rotates.
Preferably, the propulsion assembly includes slide bar, the first sliding block, the second sliding block, sliding pin and link in rhomb form mechanism,
The slide bar, first sliding block, second sliding block and the sliding pin are two and are symmetrical arranged, first sliding block
It is transversely slideably positioned in the fixed plate, second sliding block is transversely slideably positioned on the movable plate, the cunning
Bar is slideably positioned on first sliding block and is fixedly installed on second sliding block, and the sliding pin is slideably positioned in described
On slide bar, link in rhomb form mechanism transverse ends are rotatably dispose in respectively on the sliding pin of both sides, the link in rhomb form
Mechanism longitudinal direction both ends are rotatably dispose in respectively in the fixed plate and the movable plate, first sliding block and second sliding block
In any one can transversely fix.Above structure is simple, reliable.
As an improvement, the semicircle slider bottom is provided with bevel gear, cone tooth handwheel, institute are provided on the semicircular planform
State the bevel gear engagement on the bevel gear and half smooth block on cone tooth handwheel；There are one described for two tooling unit tools
Tooth handwheel is bored, when two tooling unit alignments are closed up, the cone tooth handwheel drives the round slider in the circular flat
It rotates, and can fix at an arbitrary position on platform.
Specifically, the cone tooth handwheel includes shaft, bevel gear disk, friction shim and locking wrench, the shaft is fixed
It is set on the semicircular planform, the spindle central offers threaded hole, and the bevel gear disk is rotatably dispose in the shaft
On, and the shaft end face and the bevel gear side surface flush, the locking wrench front end is provided with spiro rod section, the screw rod
Section tail end is provided with compression plate, and the friction shim is sheathed on the spiro rod section, and the spiro rod section is threadedly connected to the spiral shell
In pit；The locking wrench inside precession when, the bevel gear disk is contradicted by the friction shim, and limit by frictional force
Make the bevel gear disk rotation.Rotating bevel gear disk can easily rotate round slider, while tightening locking wrench again can be very well
Round slider is fixed.
Further specific, the friction shim includes metal layer and rubber layer, and the metal layer contacts the compression plate, institute
It states rubber layer and contacts the bevel gear disk.Rubber layer is close to bevel gear disk, increases safety, greatly reduces due to boring tooth
It is loosened caused by wheel disc rotation；And metal layer can protect rubber layer not worn by compression plate.
As an improvement, the locking arm outer cover is equipped with rubber sleeve, the rubber sleeve has sawtooth upward, the rubber
It is in lower concave arc shape to cover section.Handle is first passed through before merging two semicircular planforms overcomes spring by locking arm toward recycling, in two semicircles
Platform unclamps handle after the completion of merging, locking arm rebound, at this time due to the presence of ball head connecting rod, locking arm is close to pole, completes
Locking.The setting of rubber sleeve can increase the frictional force between locking arm and ball head connecting rod, and since rubber sleeve has saw upward
Tooth, this structure make ball head connecting rod moves upwards to be easier, move downward, need to overcome prodigious resistance, to ensure
The bulb of lower end is far from ball bowl.The setting of lower concave arc shape can increase and the contact area of ball head connecting rod, to increase frictional force.
Preferably, the lower binding post is around outer ring is constituted, the upper binding post is around composition inner ring.Structure more adduction
Reason.
As an improvement, being both provided with guiding between the fixed plate and the movable plate and the movable plate of both sides
Box member, the guide pin hole component enable two fixed plates and two movable plates to be directed at movement successively.Ensure
