Abstract

The utility model discloses flexible equipment for processing mechanical parts, and particularly relates to a flexible polishing machine for a curved inner wall for finish machining of the curved inner wall of the mechanical parts. An electric motor (5) is arranged at the right lower end of a speed reducer (4) and is connected with a grinding wheel spindle (3) through a coupling; and a flexible tire grinding wheel is arranged in an external groove (7) of the grinding wheel spindle (3) and is movably connected with the inner wall of a workpiece (1). In the flexible polishing machine, an inflating tire grinding wheel is arranged and grit gravel is attached to the outer circumferential wall of the inflating tire, the inner wall of the curved workpiece can be flexibly ground to be smooth by using the rotating tire grinding wheel. According to the flexible polishing machine, the structure is simple, the effects are remarkable, the quality of products is ensured, the efficiency is improved, the noise is reduced, and the labor intensity is reduced.

Description

The flexible sanding machine of curved surface inwall

Technical field: the utility model relates to a kind of process equipment of machine components flexibility, especially the flexible sanding machine of a kind of curved surface inwall of the fine finishining of machine components curved surface inwall use.

Background technology: at present, in machine components curved surface inwall process, have many workpiece to need polishing, particularly curve surface work pieces grinding difficulty is bigger.Many enterprises can only generally adopt offhand grinding with manually surface of the work being carried out attrition process, and hand-held polishing thickness of workpiece is wayward, and defective work piece easily, are difficult to guarantee the precision and the roughness of processing.

The utility model summary of the invention: the present utility model has overcome the drawback that former curved surface inwall processing exists, and provides a kind of tire emery wheel of inflation that utilizes that the curved surface inwall is carried out the flexible sanding machine of a kind of curved surface inwall that fine finishining is used.The technical scheme that technical solution problem of the present invention is adopted is: described motor 5 is arranged on decelerator 4 bottom righthand sides, and is connected with grinding wheel spindle 3 by shaft coupling, and flexible tire emery wheel is built in grinding wheel spindle 3 outer grooves 7, and and the inwall of workpiece 1 flexibly connect.

The beneficial effects of the utility model are: owing to designed a kind of tire emery wheel of inflation, airtyred periphery is stained with gravel on facing the wall and meditating, the inwall of the grinding curve surface work pieces of the tire emery wheel flexibility of rotating can be smooth with the inwall grinding of curve surface work pieces, thereby reduced noise.And simple in structure, effect is remarkable, has guaranteed product quality, has improved effect, has reduced noise, has alleviated labour intensity.

Description of drawings: Fig. 1 is a structure chart of the present utility model

Fig. 2 is the left view of Fig. 1

The specific embodiment: as Fig. 1, Fig. 2, shown in Figure 3, described motor 5 is arranged on decelerator 4 bottom righthand sides, and is connected with grinding wheel spindle 3 by shaft coupling, and flexible tire emery wheel is built in grinding wheel spindle 3 outer grooves 7, and and the inwall of workpiece 1 flexibly connect.

As Fig. 1, Fig. 2, shown in Figure 3, the grinding layer of sand 6 of described flexible tire emery wheel is bonded on pneumatic tire 2 peripheries face the wall and meditate.

If the utility model is adjusted the blowing pressure, the thickness of gravel and the speed of rotation of tire, can reach the precision and the roughness of multiple processing, even reach higher precision and roughness.

The course of work of the present utility model is: at first, after the movement velocity of motor is slowed down through decelerator, will move and transmission of power to grinding wheel spindle.Then, grinding wheel spindle drives the tire emery wheel and rotates, the curved surface inwall that the tire emery wheel of rotation will grinding work piece.

Operation principle of the present utility model is: because the tire emery wheel is the flexible abrasive wheel of inflation, so the shape of tire emery wheel can change along with the change of shape of curve surface of workpiece inwall.

The pressure at any position, tire emery wheel inflation back is all equally big, and the curve surface of workpiece inwall is also all the same big with the pressure that any position of tire emery wheel contact is subjected to.Therefore, any position of contacting with the tire emery wheel of the curved surface inwall that changes of radius of curvature is all can grinding smooth.
