Description
Technical Field
The invention belongs to the technical field of machining equipment for motorcycle shoe brake linings, and particularly relates to a motorcycle shoe brake lining inner arc chamfer combined grinding machine.
Background
Currently, the technological route of most motorcycle shoe brake lining manufacturers is: pressing the friction material into long tiles, cutting the long tiles into short tile single pieces, and then sequentially grinding the inner arcs of the short tile single pieces, chamfering, gluing, drying, bonding with aluminum hooves, and processing the side surfaces and the outer arcs of the hoof assembly.
Wherein, the short tile monolithic inner arc grinding and chamfering process are respectively completed on two devices:
during inner arc grinding, the lining is pushed into the gap inlet of the guide-in wheel and the inner arc grinding wheel manually, the guide-in wheel brings the lining into the gap by means of friction force, and simultaneously, the inner arc of the lining is pressed towards the inner arc grinding wheel to start inner arc grinding. Then the lining is taken out of the gap along with the continuous rotation of the guide wheel under the action of friction force, and the grinding process of the inner cambered surface is completed.
During chamfering grinding, a workpiece is manually held to slide to a chamfering grinding wheel to start chamfering at one end along the arc surface of the seat plate, when the front end of the gasket is in contact with the positioning end of the seat plate, chamfering grinding at the end is completed, then the gasket which completes unilateral chamfering is withdrawn, the gasket which completes unilateral chamfering is rotated for 180 degrees and manually held again to slide to the chamfering grinding wheel along the arc surface of the seat plate, the other end of the gasket is ground, and finally grinding chamfering at two ends of the gasket is realized
The inner arc grinding and chamfering grinding processing are both in a short tile single-chip manual mode, the labor intensity of workers is high, potential safety hazards exist in the operation process, and workpieces need to be transferred and conveyed in the process. For the production line, the production efficiency is reduced. Is not suitable for automatic production lines.
In recent years, to improve production efficiency, many manufacturers have adopted: the efficient process route of long tile grinding inner arc-chamfering-gluing-drying-cutting into a plurality of short tile linings is obviously not suitable for the efficient process route by the inner arc grinding machine and the chamfering machine which are only suitable for the short tile linings.
Some manufacturers try to apply a long tile inner arc chamfering combination machine specially designed for an automobile drum brake pad to the processing of the inner arc and chamfer of the long tile of the motorcycle. When the long tile inner arc chamfering combination machine is used, a long tile needs to be positioned on a supporting slide way and can move forwards along guide rails on two sides under the action of a conveying chain and a push plate, the outer diameter of an inner arc grinding wheel is the same as the inner arc diameter required by a product, and the front position and the rear position and the angle of the chamfering grinding wheel on the two sides can be adjusted to meet the chamfering processing requirements of different products.
However, compared with an automobile drum brake pad, the motorcycle shoe type lining has special dimensions, such as the inner arc radius, chord length and thickness which are far smaller than those of an automobile drum type lining, so that the motorcycle shoe type lining has small thickness (generally about 5 mm) and poor rigidity, and only depends on small-area contact support of a positioning slideway and guide rail guiding and limiting, a workpiece is deformed during processing, and the grinding of the inner arc surface is seriously uneven; moreover, the chord length of most motorcycle hoof type liner products is smaller than the supporting width between two supporting slideways, so that the positioning cannot be realized; even if the positioning can be carried out, the chamfering angle of some motorcycle hoof type lining products is too large, so that the chamfering grinding wheels on the two sides are easy to interfere with other mechanisms when moving forwards and backwards or rotating, and the chamfering cannot be carried out.
In conclusion, the existing automobile drum brake pad long tile inner arc chamfering combination machine is only suitable for inner arc grinding and chamfering of a very small number of large-size motorcycle shoe type liner long tiles, and the application range is very limited.
