Detreader is to be used to polish the equipment on old tire surface, mainly comprises frame, cutter head, cutter head tumbler, cutter head mobile device, cutter head frame, tire chuck for installing, tyre rotation device and electric apparatus control apparatus.On the at first rack-mounted tire chuck for installing of old tire, rotate under the drive of tyre rotation device, cutter head rotates under the drive of cutter head tumbler again, and the cutter head frame moves simultaneously, drives cutter head and polish satisfactory tire section exterior contour.The tire chuck for installing generally comprises a fixed-site chuck and a mobile chuck, be installed in the both sides of frame relatively, mobile chuck drives by rack-mounted cylinder or oil cylinder and moves, and by moving of mobile chuck rim clamp is held in fixedly between the chuck and mobile chuck.
In order to polish carcass surface satisfactory for result, to inflate polishing usually, simulate tire exactly and under running status, polish.Therefore tire will be inflated tire after being installed in fixedly between the chuck and mobile chuck, expand under gas pressure owing to tire in the gas replenishment process, it is moving to travelling backwards to promote mobile chuck, this moment will be to mobile chuck location, making fixedly, the distance between the chuck and mobile chuck keeps certain, in order to avoid mobile chuck is excessive to the moving distance of travelling backwards, lose the effect of inflation.
At present, be to adopt the method that between mobile chuck and frame, adds locating shaft to the location of mobile chuck, but, just need the locating shaft of multiple different length because size, the width of tire are different.The tire of a kind of specification of every polishing all will be changed a kind of locating shaft of length.This method is complicated operation not only, and if misoperation, locating shaft is got easily under the very big air pressure of tire, perhaps the rear base of cylinder collapses out, threat to life safety.
Summary of the invention
The utility model is at the problem that existing detreader chuck location technology exists, and a kind of location automatically, safe and reliable detreader chuck positioner can realized accurately is provided.
Detreader chuck positioner of the present utility model adopts following technical solution:
This detreader chuck positioner comprises magnetic valve, hand-operated valve, shuttle valve, oil storage pressure-bearing jar, Pneumatic and hydraulic check valve, gas-liquid mixed cylinder and control module; The gas-liquid mixed cylinder is made up of cylinder body and piston rod, and the front end of cylinder body is provided with air inlet, and the rear end is provided with inlet; The import of magnetic valve and hand-operated valve all is connected with gas circuit, and the outlet of magnetic valve is connected with an import of shuttle valve, and an outlet of hand-operated valve is connected with another import of shuttle valve and the air inlet of gas-liquid mixed cylinder simultaneously; The outlet of shuttle valve is connected with the air inlet of Pneumatic and hydraulic check valve, another outlet of hand-operated valve is communicated with oil storage pressure-bearing jar, oil storage pressure-bearing jar is connected with the inlet of gas-liquid mixed cylinder rear end by the Pneumatic and hydraulic check valve, have the displacement transducer that detects the piston rod displacement on the gas-liquid mixed cylinder, this displacement transducer and magnetic valve all are electrically connected with control module.
Magnetic valve adopts the two-bit triplet magnetic valve, and hand-operated valve adopts the 3-position 4-way hand-operated valve.
Control module adopts Programmable Logic Controller (PLC).
The utility model is located chuck by the constrictive hydraulic oil of tool not, can realize accurately location automatically under the effect of control module, and is safe and reliable, easy to use.
Description of drawings
Accompanying drawing is a structural principle schematic diagram of the present utility model.
Wherein: 1, two-bit triplet magnetic valve, 2, the 3-position 4-way hand-operated valve, 3, shuttle valve, 4, the Pneumatic and hydraulic check valve, 5, oil storage pressure-bearing jar, 6, the gas-liquid mixed cylinder.
The specific embodiment
As shown in drawings, detreader chuck positioner of the present utility model mainly comprises two-bit triplet magnetic valve 1,3-position 4-way hand-operated valve 2, shuttle valve 3, Pneumatic and hydraulic check valve 4, oil storage pressure-bearing jar 5, gas-liquid mixed cylinder 6 and control module.Gas-liquid mixed cylinder 6 is made up of cylinder body and piston rod, and the front end of cylinder body is provided with air inlet, and the rear end is provided with inlet.The import of two-bit triplet magnetic valve 1 and 3-position 4-way hand-operated valve 2 all is connected with gas circuit, the outlet of two-bit triplet magnetic valve 1 is connected with an import of shuttle valve 3, an outlet of 3-position 4-way hand-operated valve 2 is connected with another import of shuttle valve 3 and the air inlet of gas-liquid mixed cylinder 6 simultaneously, the outlet of shuttle valve 3 is connected with the air inlet of Pneumatic and hydraulic check valve 4, another outlet of 3-position 4-way hand-operated valve 2 is communicated with oil storage pressure-bearing jar 5, oil storage pressure-bearing jar 5 is connected with the inlet of gas-liquid mixed cylinder 6 rear ends by Pneumatic and hydraulic check valve 4, have the displacement transducer that detects its piston rod displacement on the gas-liquid mixed cylinder 6, this displacement transducer and magnetic valve 1 all are electrically connected with a control module (not drawing among the figure), and control module adopts Programmable Logic Controller (PLC).
The course of work of the present utility model is as follows:
According to two chuck spacings that all size tire is installed, in the program of control module, set the displacement of gas-liquid mixed cylinder 6 piston rods after all size tire is inflated in advance.Tire is handled 3-position 4-way hand-operated valve 2 after being in fixedly between the chuck and mobile chuck, makes source of the gas enter oil storage pressure-bearing jar 5, and air pressure enters Pneumatic and hydraulic check valve 4 through normal open magnetic valve, shuttle valve 3, and the spool of Pneumatic and hydraulic check valve 4 is opened.Hydraulic oil in the oil storage pressure-bearing jar 5 enters gas-liquid mixed cylinder 6 by Pneumatic and hydraulic check valve 4 under gas pressure, the piston rod that promotes gas-liquid mixed cylinder 6 drives mobile chuck and moves forward, and rim clamp is held in fixedly between the chuck and mobile chuck.Then tire is inflated, huge tire lateral thrust by the tyre inner pressure generation, force chuck to bear the counter motion of air pressure back pressure simultaneously, when the piston rod that detects gas-liquid mixed cylinder 6 when the displacement transducer on the gas-liquid mixed cylinder 6 has arrived the displacement of setting in the control module program, send signal to control module.Control module control two-bit triplet magnetic valve 1 cuts out source of the gas, the spool return of Pneumatic and hydraulic check valve 4, and hydraulic oil no longer flows backwards.Because the Incoercibility of hydraulic oil, make fixedly that distance has obtained strict control between the chuck and mobile chuck, guaranteed the blowing pressure and the quality of polishing.
In the time of need unclamping chuck, bleed off the tire internal gas pressure earlier, handle 3-position 4-way hand-operated valve 2 then and make source of the gas enter gas-liquid mixed cylinder 6, and enter Pneumatic and hydraulic check valve 4 through shuttle valve 3, the spool that promotes Pneumatic and hydraulic check valve 4 is opened.Chuck is done backhaul at gas pressure and is moved, and the hydraulic oil in the gas-liquid mixed cylinder 6 will be by the Pneumatic and hydraulic check valve of the opening 4 oil storage pressure-bearing jar 5 that flows backwards back.
