Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
A kind of clamp structure for pipe fitting process equipment, including cylinder 1, sliding slot 2 and be respectively arranged in 2 both ends of sliding slot
3 wherein at least one grip block 3 of grip block be freely slidable grip block 3.1 upper end of cylinder is equipped with pivot pin 4, grip block 3
Lower end is equipped with the connecting plate component 5 for hinged pivot pin 4.Connecting plate component 5 includes the first connecting plate 501 and the second connecting plate 502, and first connects
501 one end of plate and the hinged other end of grip block 3 and 502 upper end of the second connecting plate are hinged, and 502 lower end of the second connecting plate is articulated with axis jointly
On pin 4.The fulcrum hole 204 being inserted into for shaft is equipped in sliding slot 2,501 middle position of the first connecting plate is equipped with right with fulcrum hole 204
The rotating hole 5011 answered；
It pushes the second connecting plate 502 to enclose the first connecting plate 501 in horizontal development when 1 uplink of cylinder to rotate around the axis to push
Grip block 3 clamps pipe fitting, and when grip block 3 clamps pipe fitting, the first connecting plate 501 is formed self-locking with 3 Relative vertical of grip block.
In the present embodiment, the grip block 3 at 2 both ends of sliding slot is mobilizable grip block 3, and cylinder 1 is upward by pivot pin 4
When pushing connecting plate component 5, connecting plate component 5 pulls the grip block 3 at 2 both ends of sliding slot to be drawn close to centre simultaneously thus by pipe to be processed
Material is fixed.The grip block 3 at 2 both ends of sliding slot can be fixed in sliding slot 2 another for one and pass through company in another embodiment
Board group part 5 connects cylinder 1, and when cylinder 1 pushes up connecting plate component 5 by pivot pin 4, connecting plate component 5 pulls mobilizable clamping
Block 3 is drawn close to fix tubing to be processed to the grip block 3 of another fixation.
On the other hand after the first connecting plate 501 are straightened in cylinder 1, the Impact direction of grip block 3 is vertical with the direction of motion at this time,
Therefore cylinder 1, which continues offer pulling force grip block 3, will not continue to cause to squeeze to pipe fitting to form self-locking state.
In conclusion the clamping device both can to avoid grip block 3 during clamping due to excessive velocities or power
Degree causes greatly pipe fitting to be pinched or deform very much, and can prevent its loosening to the clamping of pipe fitting reinforcement.
In the present embodiment, sliding slot 2 is U-shaped sliding slot 2, and 2 inner wall two sides of sliding slot are equipped with the first groove 201,3 outer wall of grip block
Two sides are equipped with the second groove 301, sliding rail 6 are equipped between sliding slot 2 and grip block 3,6 one end of sliding rail is fixed in the first groove 201
The other end is inserted into the second groove 301, and grip block 3 is slided in sliding slot 2 by sliding rail 6.Thus grip block 3 can be prevented in sliding slot
Generating offset in 2 when sliding slides it more steadily, to improve the stability of the clamp structure.
In the present embodiment, be equipped with fixation hole 202 on the first groove 201 and sliding rail 6, sliding rail 6 by fixation hole 202 with
First groove 201 is fitted close.Thus can anti-anti-slip track 6 generated in sliding slot 2 offset improve the clamp structure stability.
In the present embodiment, the first groove 201 is horizontally set on 2 inside of sliding slot.It can make grip block 3 from there through cylinder 1
It draws close in the horizontal direction, so that tubing horizontal-clamping is easy to operate.
In the present embodiment, baffle 7 is equipped on the outside of connecting plate component 5.Thus it can prevent from foreign matter from entering in connecting plate component 5 to cause
Connecting plate is stuck.
In the present embodiment, the first connecting plate 501 and 502 both ends of the second connecting plate are equipped with hinge hole 503, in hinge hole 503
It is equipped with bolt.In the present embodiment, connecting plate component 5 is hinged composition by the first connecting plate 501 and the second connecting plate 502.
In the present embodiment, the first connecting plate 501 is longer than the second connecting plate 502.Since at this time therefore power arm is greater than resistance arm
The reinforcement that the grip block 3 can be achieved clamps.
In the present embodiment, reinforcing rib 203 is equipped between 2 liang of inner walls of sliding slot.Reinforcing rib 203 and sliding slot in the present embodiment
2 are integrally formed, and thus can prevent sliding slot 2 from deforming, improve the service life stabilizability of the clamp structure.
The operation logic of the clamp structure are as follows:
Start 1 downlink of cylinder when use and drive 4 downlink of pivot pin, pivot pin 4 drives the second connecting plate 502 to make its contraction, and first connects
501 lower end of plate closes up in dynamic lower shrink of effect of the second connecting plate 502, at this time the first connecting plate 501 centered on rotating hole 5011 around
Shaft rotation, because the 501 upper end direction of motion of the first connecting plate and the lower end direction of motion are on the contrary, therefore 501 upper end band of the first connecting plate
Dynamic two grip blocks 3 counter motion in the horizontal direction in sliding slot 2, two grip blocks 3 are gradually disengaged with pipe fitting.
The second connecting plate 502 is pushed to make it in expanding horizontally by pivot pin 4 when 1 uplink of cylinder, 501 lower end of the first connecting plate is the
It being softened under the effects of two connecting plates 502 is dynamic, the first connecting plate 501 is rotated around the shaft centered on rotating hole 5011 at this time, and subsequent the
One connecting plate, 501 upper end drives two grip blocks 3 to move toward one another in the horizontal direction in sliding slot 2, until two grip blocks 3 are tight with pipe fitting
Contiguity touching, so that pipe fitting is carried out horizontal-clamping, at the same time the first connecting plate 501 and grip block 3 keep it is vertical complete it is self-locking.
The principle that the reinforcement of the clamp structure clamps are as follows:
As shown in figure 5, when pivot pin 4 pushes the expansion movement of the second connecting plate 502, the hinge of the second connecting plate 502 and pivot pin 4 at this time
Connecing is the point of application at hole 503, is fulcrum at the hinge hole 503 of the second connecting plate 502 and the first connecting plate 501.Therefore in the second connecting plate
Since therefore effective arm 100 is progressively longer for 502 shape invariance of the second connecting plate when 502 expansion, to complete reinforcement clamping.Such as figure
Shown in 5, the left side is 100 schematic diagram of arm of force when grip block 3 unclamps, and the right is 100 schematic diagram of arm of force when grip block 3 clamps.
Obviously the power arm 100 when 3 clamping self-locking of grip block of the right is greater than the power arm 100 when the left side does not clamp.
Above-described is only some embodiments of the utility model, for those of ordinary skill in the art,
Without departing from the concept of the present invention, various modifications and improvements can be made, these belong to practical
Novel protection scope.
