Abstract

The invention relates to abrasive machining using belt grinding and can be used in the processing of workpieces such as bobbins for threads. The purpose of the invention is to expand the functionality of the device. The device consists of a surface table mounted on the frame with peripheral spindle assemblies, a door in the form of a sector enveloping the periphery of the table, and two tape mechanisms installed opposite the top and bottom relative to the guides feeding the workpiece to the spindle assembly. The guides are made in the form of closed belts rotating in opposite directions at different speeds. 2 yl

Description

The invention relates to abrasive processing using belt grinding and can be used in the processing of workpieces such as bobbins for threads.

The purpose of the invention is to expand the functionality of the device.

Figure 1 shows the proposed device, the cut; figure 2 is the same, top view (without the top of the table).

The device comprises a frame 1, a drive 2 of rotation of the table and workpieces 3, polishing sectors - closers 4 with an abrasive surface, fixed with the possibility of elastic pressing to the workpieces on shock absorbers 5 and an arcuate plate - an emphasis 6, which is rigidly fixed on the frame 1. Coaxially with the table of the device mounted on a drive shaft of a large-diameter gear 7, leading to spindle assemblies consisting of 8 pinch centers 9 driven by gears. Guides 10 in the form of driving tapes are rotatable in directions opposing back to each other. On top and bottom with respect to the guides, there are installed tape-driving mechanisms 11. The spindle assemblies are mounted between two swivel table covers: the upper 12 and the lower 13.

The device works as follows.

When the drive 2 is turned on, movement is transmitted through the drive shaft to gear 7, which drives the spindle assemblies through gears 8. The billets 3, rolling from the accumulator (not shown) along the guides 10, are machined at the ends with abrasive tapes driven by tape-carrying mechanisms 11. When the set position is reached (Fig. 2), the workpiece 3 is automatically pressed by the centers 9 of the spindle assembly and starts with them rotate and move around the periphery of the turntable. At the same time, contact with abrasive surfaces.

closers 4, the blanks are machined around their periphery. The workpiece processing cycle ends with the removal of the finished part with an automatic puller (not shown). Thus, the device allows to expand the number of automatically processed surfaces of various types when processing blanks of parts such as coils for threads.
