Abstract
The utility model relates to a transmission gear realizing synchronous level motion of fastening mechanisms, which is mainly used for a large sealing head spinning flanging machine with a two-step method. The utility model is characterized in that the utility model is driven by a motor, and three chain wheels and three asymmetric leading screws connected with the chain wheels are driven by two chains; the two chains altogether adopt five tension wheels of which positions can be adjusted to exert bidirectional tension. As a consequence, an upper fastening mechanism and a lower fastening mechanism can respectively realize mechanical bidirectional synchronous horizontal motion along an upper guide rail and a lower guide rail.
Description
The utility model relates to a kind of clamp mechanism that is used for the two-step method end enclosure rotary extrusion flanger, to realize the transmission device of the mechanical bi-directional synchronization horizontal movement of upper and lower clamp mechanism accurately and reliably.
According to the flanging process requirement, must carry out horizontal displacement operation at equipment upper cover blank, that the upper and lower clamp mechanism that promptly clamps blank should be able to be finished is two-way (about) the level of synchronization motion.In Italian Boldrinni company relevant device, horizontal movement is by upper and lower each servomotor, drive upper and lower clamp mechanism left and right horizontal motion by three ball-screws (on once two) respectively, but this kind mechanism control system complexity, cost is higher.
The purpose of this utility model is to propose a kind of replacement scheme under the condition that does not change three lead screw transmission, adopts the Purely mechanical transmission, so that upper and lower clamp mechanism can realize reliably that also two-way horizontal is synchronized with the movement.
The utility model be achieved in that by a motor by two chain drive respectively with a rhizoid thick stick of upper clamping mechanism and the coaxial sprocket wheel of two rhizoid thick sticks of following clamp mechanism, chain is by five two-way tensionings of regulating wheel that the position is adjustable.This adjustable two-way tensioning mode produces various accumulated errors owing to having eliminated because of chain is long, thereby can realize the two-way horizontal motion of upper and lower clamp mechanism.Two-way tensioning is essential, if only one-sided two regulating wheels are set, because what apply is unidirectional tensile force, then can't realize the horizontal synchronization campaign of clamp mechanism along left and right sides both direction.
Accompanying drawing the 1, the 2nd, structure principle chart of the present utility model.
Embodiment:
As shown in drawings, the related transmission device of the utility model comprises motor (containing decelerator) 2, chain 5,1, sprocket wheel 3,4,7,22,24, leading screw 8,21,25, regulating wheel 11,12,17,18,23, regulating wheel fixed head 9,14,15,20,26, screw 10,13,16,19,27; The sprocket wheel 3,4 that links with motor 2 output shafts is by chain 5,1 drive sprocket 7 and 22,24, and sprocket wheel 7,22,24 is coaxial with leading screw 8,21,25 respectively, and three rhizoid thick sticks drive upper and lower clamp mechanism 6,28 and are synchronized with the movement along the guide rail left and right horizontal; Regulating wheel 11,12,17,18,23 is fixed on the fuselage with screw 10,13,16,19,27 respectively by regulating wheel fixed head 9,14,15,20,26, and chain is carried out two-way tensioning; Screw hole on each fixed head is a strip, so each regulating wheel position is adjustable.
The utility model applies two-way tensile force to two chains, so can realize the bi-directional synchronization horizontal movement of clamp mechanism owing to adopted five two-way tensioning modes of regulating wheel; And each regulating wheel position is adjustable, when chain, sprocket wheel serious wear, still can guarantee tensioning, realizes bi-directional synchronization horizontal movement requirement.
