Description
(1) technical field
The utility model relates to a kind of tyre building machine structure, is specially the cord guiding mechanism of tyre building machine bandage drawn-back device.
(2) background technology
The bandage drawn-back device of tyre building machine, a plurality of jaws that on the circumference of bandage drawn-back device frame, evenly distribute, jaw is used to clamp bandage, so that device is drawn in make-up machine with it.When last bandage, according to bandage cylindrical size, carry out the adjustment of certain limit to the jaw of circle distribution, adapt to the cylindrical of bandage.The employed guiding mechanism of bandage drawn-back device of the tyre building machine of present domestic current, most of adopt the chain-type transmission, each jaw connects through chain, after driving a jaw and moving, it is corresponding mobile that chain drives other jaw, and then adjust the diameter range of jaw circumference.This structure distinct issues are: when the chain drive amount of movement drives some jaws, because this body structure of chain belongs to loosely connected form, the defective that amount of movement postpones appears in the transmission of chain inevitably, the jaw that promptly occurs on the circumference moves nonsynchronous phenomenon, cause the site error between last jaw of first jaw that directly is activated and chain drive very big, so just make the bandage center circle occur tire quality being caused negative effect than large deviation.In addition, chain structure causes whole chain structure more inconsistent through frequent and adjustment chronically, and each section error strengthens, and keeps in repair also very difficult.The long-term bandage centre deviation that uses the rear chain transmission to cause will be more remarkable.
(3) utility model content
The purpose of this utility model is the cord guiding mechanism of a kind of tyre building machine bandage drawn-back device of design, guarantees the same moved further of jaw, avoids the deviation at bandage center.
The cord guiding mechanism of the tyre building machine bandage drawn-back device of the utility model design, comprise a plurality of jaws that are fixed in the tyre building machine bandage drawn-back device mainframe cylinder, be installed on the spiral disk of mainframe cylinder outer end in addition, this spiral disk is annular disc, its external diameter equals or is slightly smaller than the internal diameter of bandage drawn-back device cylinder mainframe cylinder, a plurality of archimedes spiral grooves corresponding with jaw evenly distribute on it, archimedes spiral groove is a curved groove, and the center line of each groove is one section identical Archimedes spiral.At least 3 pairs of rotating support rollers are installed on the outer face of bandage drawn-back device mainframe cylinder, and the circumference that support roller constitutes is concentric with the mainframe cylinder, and spiral disk is installed between the support roller.Connecting plate is positioned at the inner face of frame tube, spiral disk, the inner jaw assembly that connects of connecting plate, and there is the connection roller bearing outer end, connects in the archimedes spiral groove of roller bearing insertion spiral disk.
Rotation seat is installed in bandage drawn-back device mainframe, screw is arranged on the rotation seat, clamping plate are two overlapping straight plates up and down, the one end is clamped and is fixed in the spiral disk edge, the other end outwards stretches to mainframe cylinder outer rim, screw, bottom that the active screw rod passes rotation seat are inserted between the clamping plate, and train wheel bridge has chute, and initiatively the slide block on the screw rod is positioned at the chute of clamping plate.
When initiatively screw rod rotates, slide block slides in the chute of clamping plate, drive clamping plate, spiral disk is rotated on the circumference that support roller forms, the rotation of spiral disk and then the connection roller bearing that drives each connecting plate move along archimedes spiral groove, and the circle diameter of jaw assembly is adjusted in the mobile realization of connecting plate synchronously.
The advantage of the cord guiding mechanism of the utility model tyre building machine bandage drawn-back device is: 1, use the spiral disk of an integral body to drive all jaw assemblies simultaneously, avoided each jaw site error each other, the center line that guarantees bandage can not depart from frame central, helps improving tire quality; 2, the compact conformation of this guiding mechanism, whole rigidity is strong; Guiding mechanism than chain-type improves a lot; 3, be convenient to regulate, and regulate the influence of precision very for a short time repeatedly, can use for a long time.
