Description

A kind of big regulated quantity connecting rod attachment structure
Technical field
The utility model is related to a kind of big regulated quantity connecting rod attachment structure, belongs to metal forming machinery technical field, particularly should For the large-scale multi-link lever press using non-guide pillar guide pin bushing guidance mode.
Background technology
Medium-and-large-sized two point and 4 multi-link lever press are generally used for the system of the stamping parts such as automobile panel, auto parts machinery Make, the advantages of possess energy-saving and environmental protection and strong Technological adaptability.When stroke is larger, output connecting rod is excessive with guide pillar angle, no Guide pillar guide pin bushing is preferably used as guidance mode.It is general using output connecting rod and sliding block when die-filling height of sliding block regulated quantity is smaller Part(Typically pass through adjusting screw rod)It is directly connected to.In order to meet during more process requirements, then larger height of packing compact is needed , now with slider part should not be directly connected to output connecting rod by regulated quantity(Additional bending moment is produced at adjusting screw rod position).Adopt more Guide rail is installed at adjusting screw rod, while increasing spigot surface in slide body, and guide rail is carried out spacing(Preset clearance).Due to The presence in gap, still can produce certain additional bending moment, and it is complicated, it is necessary to the accuracy of manufacture higher to be oriented to portion structure.
Utility model content
The purpose of this utility model is the defect for overcoming prior art to exist, and solves above-mentioned technical problem, is proposed a kind of Big regulated quantity connecting rod attachment structure, by by the point of application in two point or 4 multi-link lever press in the horizontal direction(Right and left To)On be joined directly together by connecting rod, in punching course push and pull system produce side force born by connecting rod and mutually supported Disappear, simplify structure.Simultaneously because two point has been rigidly connected into one by connecting rod, rigidly it is improved.When die-filling During Height Adjustment, once two point is asynchronous, due to the presence of connecting rod, cause to adjust, realize the protection to lathe.
The utility model is adopted the following technical scheme that:A kind of big regulated quantity connecting rod attachment structure, it is characterised in that if including Dry key-bolt, several connecting rods, several adjusting screw rods, several output connecting rods, the adjusting screw rod is arranged at described The middle part of key-bolt, several symmetrical nestings of connecting rod are arranged at the left and right sides of the key-bolt, the output connecting rod Symmetrical to be arranged between the connecting rod and the adjusting screw rod, the output connecting rod is nested in the periphery of the key-bolt On.
Preferably, the inside of output connecting rod is further opened with exporting connecting rod bearing shell, and output connecting rod bearing shell nesting is arranged at key-bolt On periphery, output connecting rod is connected by exporting connecting rod bearing shell with key-bolt.
Preferably, open up jagged above adjusting screw rod, indentation, there is provided with the screw being engaged, key-bolt passes through spiral shell The cooperation of nail and breach is compressed with adjusting screw rod and is connected.
Preferably, connecting rod is fastenedly connected by holding screw with key-bolt, for connecting rod is limited with key-bolt Position is fixed.
Preferably, between connecting rod and output connecting rod, between output connecting rod and adjusting screw rod gap is offered.
The beneficial effect that the utility model is reached:(1)The point of application is directly connected to by connecting rod at the utility model two, Realize that the side force in punching course is cancelled out each other, eliminate possible additional bending moment;(2)Design is simplified simultaneously, is reduced Manufacturing cost;(3)When height of packing compact is adjusted, if two point is asynchronous, the further action of mould adjusting mechanism can be avoided, realized Protection to whole machine.
Brief description of the drawings
Fig. 1 is the structural representation of one embodiment of the present utility model.
Fig. 2 is the structural representation of the C-C direction views of Fig. 1.
The implication marked in figure:1- connecting rods, 2- key-bolts, 3- adjusting screw rods, 31- screws, 4- output connecting rods, 41- is defeated Go out connecting rod bearing shell, 5- holding screws.
Specific embodiment
The utility model is further described below in conjunction with the accompanying drawings.Following examples are only used for clearly illustrating this The technical scheme of utility model, and protection domain of the present utility model can not be limited with this.
Fig. 1 is the structural representation of one embodiment of the present utility model.Connect the utility model proposes a kind of big regulated quantity Bar attachment structure, including several key-bolts 2, several connecting rods 1, several adjusting screw rods 3, several output connecting rods 4, adjust Section screw rod 3 is arranged at the middle part of key-bolt 2, and several symmetrical nestings of connecting rod 1 are arranged at the left and right sides of key-bolt 2, export Connecting rod 4 is symmetrical to be arranged between connecting rod 1 and adjusting screw rod 3, and output connecting rod 4 is nested on the periphery of key-bolt 2.
Fig. 2 is the structural representation of the C-C direction views of Fig. 1.The inside for exporting connecting rod 4 is further opened with exporting connecting rod bearing shell 41, The output nesting of connecting rod bearing shell 41 is arranged on the periphery of key-bolt 2, and output connecting rod 4 is coordinated by exporting connecting rod bearing shell 41 with key-bolt 2 Connection.
Used as a kind of preferred embodiment, the top of adjusting screw rod 3 opens up jagged, and indentation, there is provided with the spiral shell being engaged Nail 31, key-bolt 2 is compressed with adjusting screw rod 3 by the cooperation of screw 31 and breach and is connected.
Used as a kind of preferred embodiment, connecting rod 1 is fastenedly connected by holding screw 5 with key-bolt 2, for that will connect Bar 1 is fixed with key-bolt 2.
As a kind of preferred embodiment, between connecting rod 1 and output connecting rod 4, between output connecting rod 4 and adjusting screw rod 3 Offer gap.
Operation principle of the present utility model:By taking two-point press as an example, by connecting rod 1 at two by the sliding block point of application A, B It is attached.When forcing press punching press, the side force that output connecting rod 4 is produced is acted directly in connecting rod 1, it is born pressure Power, and sliding block is not subject to side force, can improve the operational reliability at slider guide position.When height of packing compact adjustment is carried out, Once it is asynchronous at A, B two, due to the connection of connecting rod 1, will lead to not carry out height of packing compact adjustment, so as to realize to connecting more The protection of bar large pressing machine bed.
The above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art For art personnel, on the premise of the utility model know-why is not departed from, some improvement and deformation can also be made, these change Enter and deform also to should be regarded as protection domain of the present utility model.
