Description
Technical field
The present invention relates to the assembling field of plastic extruder, relate in particular to the installation adjusting method and the device of single screw extrusion machine machine barrel.
Background technology
Vitals in the extruder is machine barrel and screw rod, the serviceability and the life-span of the processing of machine barrel and screw rod, assembly method and accuracy affects extruder.The more important that the installation of machine barrel need guarantee is: the center line of center line and speed reducer output shaft that make the screw barrel hole guarantees screw rod and speed reducer output shaft concentric on same straight line.But, because the machine barrel self gravitation, after the bolt at speed reducer output shaft place is tightened, machine barrel one end can sink to causing the machine barrel center line not with speed reducer output shaft in this problem of same straight line.Be head it off; The single screw extrusion machine machine barrel is installed the method for adjusting at present has following two kinds: the one: proofread and correct the levelness of adjusting frame with level meter after putting frame well; Until frame at grade; Install reductor afterwards, hang machine barrel with driving again, be fixed by bolts to an end of machine barrel on the reductor; Proofread and correct the axiality of machine barrel and speed reducer output shaft then, the method for adjustment is to be placed on the machine barrel top to level meter, the levelness of check machine barrel; And the position up and down of adjustment machine barrel support; Make machine barrel on horizontal plane, the screw on the lock bracket is fixed machine barrel then.Other parts are installed afterwards.The 2nd: after putting frame well reductor is installed; Be installed in machine barrel on the reductor afterwards, with the distance of tape measure speed reducer output shaft terminal tube peak to the frame bottom, this distance deducts the radius of this position machine barrel then; Obtain the distance L 1 of machine barrel center line to the frame bottom; And then measure the distance of bracing frame place machine barrel peak to the frame bottom, this distance deducts here that the radius of machine barrel obtains the distance L 2 of machine barrel center line to the frame bottom, adjusts the bolt at bracing frame place; Make L2 equate with L1, show that machine barrel installs this moment.Have following defective through analyzing above-mentioned two kinds of methods: in first method, will carry out the adjustment of levelness with level meter to frame in advance, bother with the level meter adjustment, the accuracy of adjustment is not high yet in addition; Even the levelness of frame is very accurate; But because processing and installation errors can not guarantee the speed reducer output shaft certain level, after this just inaccurate with level meter adjustment machine barrel; Even machine barrel center line level can not guarantee that machine barrel and speed reducer output shaft are coaxial.In the second approach; With the distance of ruler measurement machine barrel peak to frame; Deduct the radius of machine barrel again, such method one is when measuring, to guarantee the degree of accuracy of measuring, the 2nd, and what measure is the peak of machine barrel; Be at indirect survey machine barrel center line, so this installation method can not reach result accurately.
Summary of the invention
To the deficiency in the art methods; The present invention provides a kind of method and apparatus that the adjustment extruder barrel is installed simply and easily; The axis of ability Direct Test and adjustment machine barrel axis and speed reducer output shaft uses these apparatus and method can well guarantee the axiality of machine barrel and speed reducer output shaft.
It is as follows that the present invention installs the technical scheme that the method for adjustment single screw extrusion machine machine barrel adopts: 1) on frame, fix reductor, bracing frame is contained on the column, machine barrel is fixed on the reductor and tightens the adjustment bolt; 2) first axle is inserted in the screw hole of machine barrel left end, second axle is inserted in the speed reducer output shaft right-hand member hole; 3) open the laser switch of generating laser, laser beam penetrates and behind machine barrel endoporus, speed reducer output shaft endoporus, big centre bore, arrives on the dash receiver successively along little centre bore; 4) position of observation hot spot on dash receiver; When laser beam drops on the center of dash receiver, the center line that shows machine barrel inner hole centreline and speed reducer output shaft on same straight line, otherwise; Then adjust the adjustment bolt on the bracing frame, drop on the center of dash receiver up to hot spot.
The technical scheme that the present invention installs the device employing of adjustment single screw extrusion machine machine barrel is: the bottom of device is a frame; Frame right-hand member top is provided with reductor, and the frame left end vertically connects column, and the column upper end connects bracing frame through the adjustment bolt; Bracing frame connects the machine barrel stage casing of horizontal positioned; The machine barrel left end is an emitter, and the machine barrel right-hand member connects speed reducer output shaft, and the speed reducer output shaft right-hand member is a receiving system; Emitter comprises first axle and generating laser, and the center of first axle is coaxial to have that a little centre bore, left end connect generating laser, the right-hand member gap is enclosed within the machine barrel endoporus; The equal conllinear of central shaft of the laser beam that generating laser sends and the central shaft of little centre bore and machine barrel endoporus, little center-hole diameter is greater than the diameter of laser beam; Receiving system comprises second axle and dash receiver; The coaxial big centre bore that has diameter greater than little center-hole diameter in the center of second axle; The little gap of the left end of second axle is enclosed within the speed reducer output shaft endoporus, right-hand member is fixedly connected dash receiver through support, and the center of dash receiver is vertical with the second axle center line with center conllinear, the end face of big centre bore; In dash receiver, be provided with cross hairs and round wire in the heart.
The present invention adopts the beneficial effect that has after the technique scheme to be: when the adjustment machine barrel is installed, saved conventional method of operating, needn't adjust the levelness of frame with level meter; Any data of ruler measurement needn't be used, the error that causes because of measurement can be eliminated, simple to operate; Observe directly perceived; But the axis of Direct Test and adjustment machine barrel axis and speed reducer output shaft is beneficial to the axiality that guarantees screw barrel hole and speed reducer output shaft, improves efficiency of assembling.
