Description
Technical field：
It the utility model is related to punching machine drive technology field, and in particular to a kind of compact mechanical with guide pillar
Driver of press.
Background technology：
At present, punching machine connecting rod and sliding block are connected with two kinds, and one kind is that connecting rod and sliding block are direct-connected, this structure letter
It is single, but the connecting rod due to rotating plus swinging will pass through the bottom plate of main transmission casing, cause main transmission casing to close, and transmission is only
Can half-closed lubricating system, while the guide rail that sliding block can only be leaned on itself is oriented at last, guiding accuracy is poor, and offset load resistance is weak.
Another kind is to be connected between connecting rod and sliding block by guide pillar, this complicated, but the motion of connecting rod is completely in main transmission box
Interior, transmission is enclosed lubricating system, and sliding block is oriented to simultaneously by the guide rail on itself and guide pillar, and guiding accuracy is good, offset load resistance
By force.But the transmission mechanism with guide pillar, due to guide pillar space-consuming, causes transmission mechanism space-consuming to add there is also a problem
Greatly, machine shape size is increased accordingly, and for being engaged in Forging Technology power Relatively centralized, lifting surface area is small, and work top will
Little forging and stamping are asked to process, such as slab punching press pressure, cold-extruded, stretching etc., because not needing so big table top at all, cause to set
Standby utilization rate is not high.
Utility model content：
The purpose of this utility model is exactly to make up the deficiencies in the prior art, there is provided a kind of compact with guide pillar
Punching machine transmission device, it has the advantages that compact-sized, reliable transmission stablizes, occupies little space, saves material, solves existing
There is problem present in technology.
The utility model is that technical scheme is used by solving above-mentioned technical problem：
A kind of compact mechanical driver of press with guide pillar, including transmission case body, interior be provided with of transmission case body pass
Moving axis, power transmission shaft are provided with eccentric gear, connecting rod are connected with eccentric gear, and connecting rod lower end is connected by connecting pin with guide pillar,
Guide pin bushing is provided between guide pillar and transmission case body, guide pillar lower end is connected with sliding block, and the guide pillar is provided with close to the side of eccentric gear
Indent continuing surface.
Bearing shell is provided between the power transmission shaft and transmission case body.
The eccentric gear passes through connecting key and transmission axis connection.
Overbank face is provided between the continuing surface and side wall of the guide pillar.
The utility model uses such scheme, for technical problem existing for existing machinery driver of press, design
A kind of compact mechanical driver of press with guide pillar, it is real by designing power transmission shaft, eccentric gear, connecting rod, guide pillar
Now the movement locus of sliding block is accurately controlled, and then improves kinematic accuracy；By in guide pillar close to the side of eccentric gear
Indent continuing surface (milling out a plane) is designed, and then makes overall structure structure is compacter, and space-consuming is smaller to contract,
Because transmission device is symmetrical design event, compact overall structure more highlights, and space-consuming is smaller.
Brief description of the drawings：
Fig. 1 is structural representation of the present utility model；
Fig. 2 is side view of the present utility model；
Wherein, 1, transmission case body, 2, power transmission shaft, 3, eccentric gear, 4, connecting rod, 5, connecting pin, 6, guide pillar, 7, guide pin bushing, 8,
Continuing surface, 9, bearing shell, 10 connecting keys, 11, overbank face.
Embodiment：
The utility model is described further with embodiment below in conjunction with the accompanying drawings：
As shown in Figure 1-2, a kind of compact mechanical driver of press with guide pillar, including transmission case body 1, transmission
Power transmission shaft 2 is provided with casing 1, power transmission shaft 2 is provided with eccentric gear 3, connecting rod 4 is connected with eccentric gear 3, and the lower end of connecting rod 4 leads to
Cross connecting pin 5 to be connected with guide pillar 6, guide pin bushing 7 is provided between guide pillar 6 and transmission case body 1, the lower end of guide pillar 6 is connected with sliding block, guide pillar 6
Indent continuing surface 8 is provided with close to the side of eccentric gear 3, by designing power transmission shaft 2, eccentric gear 3, connecting rod 4, guide pillar 6, is realized
The movement locus of sliding block is accurately controlled, and then improves kinematic accuracy；By in guide pillar 6 close to the side of eccentric gear 3
Indent continuing surface 8 (milling out a plane) is designed, makes guide pillar upper end inwardly and then overall structure is more stepped up to contract, structure
Gather, space-consuming is smaller, and because transmission device is symmetrical design event, compact overall structure more highlights, space-consuming
It is smaller.
Bearing shell 9 is provided between power transmission shaft 2 and transmission case body 1.
Eccentric gear 3 is connected by connecting key 10 with power transmission shaft 2.
Overbank face 11 is provided between the continuing surface 8 and side wall of guide pillar 6, ensures the structural strength of guide pillar 6.
The course of work of the present utility model：
Power transmission shaft 2, which rotates, first drives eccentric gear 3 to rotate, and eccentric gear 3 rotates drivening rod 4 and rotates and swing, and enters
And driving guide pillar 6 to be moved up and down along guide pin bushing 7, band movable slider is accurately moved up and down guide pillar 6 again, because guide pillar 6 is close
Indent design has been done in the side of eccentric gear 3, and then transmission device entirety lateral dimension reduces, and makes drive mechanism compacter,
Save material, reduce space-consuming.
Above-mentioned embodiment cannot function as the limitation to scope of protection of the utility model, for the skill of the art
For art personnel, any alternate modification or conversion made to the utility model embodiment all fall within guarantor of the present utility model
In the range of shield.
Part is not described in detail for the utility model, is the known technology of those skilled in the art of the present technique.
