Description

Ball-grinding machine

The utility model relates to a kind of ball crusher.

The processing of steel ball is that grinding forms on grinding ball specialized machine at present, common ball crusher comprises support, transmission mechanism, hoisting mechanism, fixed head and the turnover ball-collecting rack that radially is provided with thereof, axle bed and the internal fixation plate axle thereof that support is provided with above, and goal road and ball outlet channel between turnover ball-collecting rack and hoisting mechanism.Said transmission mechanism comprises fuel tank and motor, pressure pull bar, hydraulic cylinder, transmission case and rotor plate.Said hoisting mechanism comprises that body rises device base, lifter transmission case and ball lifter.Mainly utilize the plate face of fixed head and rotor plate to contact the purpose that the grinding steel ball reaches processing with ball in this mechanism, this fixed head is circular flat board, wherein be processed with ball track in advance on the plate face of fixed head, steel ball just rolls in ball track, because the relative motion of fixed head and rotor plate, make steel ball between the fixed head of executing pressure and rotor plate, make circular motion, thereby be subjected to grinding, become qualified product.Because driving steel ball, the rotation of rotor plate follow rotor plate to rotate along same direction, and the effect that rolls between steel ball and the rotor plate, make the plate face become the smooth flat that is unfavorable for grinding, thereby Grinding Machining Quality is difficult for guaranteeing that working (machining) efficiency is low.

The utility model improves at the problem that prior art exists, and provides a kind of and can guarantee the crudy requirement, a kind of ball crusher that working (machining) efficiency is high.

The utility model is achieved by following manner: a kind of ball crusher, comprise support, transmission mechanism, hoisting mechanism, fixed head and the turnover ball-collecting rack that radially is provided with thereof, axle bed that support is provided with above and interior fixed head axle thereof and goal road and the ball outlet channel between turnover ball-collecting rack and hoisting mechanism, wherein transmission mechanism comprises fuel tank and motor, pressure pull bar, hydraulic cylinder, transmission case and rotor plate, it is characterized in that on the fixed head in the turnover ball-collecting rack abrading block automatic grinding feed mechanism being set.This mechanism mainly is moving forward and backward of control abrading block, and with the plate face of polishing rotor plate, rotor plate is regrinded and cut steel ball then.

Said abrading block automatic grinding feed mechanism, a motor and reduction box are arranged, it drives the splined shaft that is connected with the drive II by belt, drive I and drive II and rotates, the splined shaft front portion can move forward and backward for leading screw, be provided with the upper plate of the hollow shaft sleeve of two ends symmetry before the leading screw, two hollow shaft sleeve outer ends are provided with the advance and retreat switch, be provided with lower roof plate before the upper plate, two apical axis are arranged on it, two apical axis are inserted in two hollow shaft sleeves of upper plate, upper plate and down decide to be provided with between the plate top spring is provided with abrading block at the lower roof plate front end.

The center of above-mentioned said fixed head is processed with axis hole, be processed with ball track on its plate face, this ball track is set for the eccentric, little, the inefficient deficiency of grinding of frictional force when the rotor plate that can overcome original equipment like this rotates with fixed head is concentric, and the design can produce the dislocation increased friction, improved grinding efficiency.

Operation principle of the present utility model and process are: as the K that closes a switch, and the time relay sj adhesive, it is normally closed to be broken as an action by being incorporated into, because the switch WK that advances ₁In normally closed position and the action of SJ point, make the relay J adhesive, relay J ₁Make the J self-locking, J ₂, J ₃Closed motor just changes motor through the molten device C of electricity, drives leading screw and travels forward, and make upper plate head on lower roof plate by the top spring, and promote abrading block at last and move ahead, and the plate face of grinding rotor plate, thereby increased its degree of roughness with the grinding steel ball, improve working (machining) efficiency.Along with moving forward of leading screw, two apical axis of lower roof plate touch the switch WK that moves forward and backward when moving to the end of two hollow shaft sleeves of upper plate ₁And WK ₂, make the switch WK that advances ₁Normally closed point disconnect, retreat switch WK ₂Normal battle closed, like this, relay J stops adhesive, J ₂, J ₃Disconnection makes motor out of service, owing to retreat switch WK ₂Normal battle closure and relay J stop, making J ₄, J ₅Normally closed closed, the anti-phase power supply of capacitor C drives motor D counter-rotating, and leading screw is withdrawed from, and makes during to certain position to retreat switch WK ₂The normal battle disconnects, and motor stops operating, and finishes the primary feed of abrading block, moves again through back time relay sj after a while and puts action repetition said process next time.

The utility model is compared with prior art; Have rational in infrastructurely, can guarantee crudy, frictional force is big, characteristics such as working (machining) efficiency height.
