SU1756118A1 - Device for bilateral grinding of cylindrical part ends - Google Patents

Abstract

Use: in the technique for two-sided grinding of flat products on end faces of machine tools, in particular rings of barium ferrite with an outer diameter of 60-140 mm and a height of G-15 mm. Essence: the device contains guides in the form of a support bracket (1), as well as input exit cheeks and a flexible tape (4). The supporting blade is made with a crescent-shaped convex working surface and is installed between the grinding wheels (2), and the belt conveyor is located outside the grinding wheels, above the treatment area. In order to supply the coolant, the knife is made hollow with side holes, and a friction coating is made on the working surface of the knife; pf ls, 6 Il. 5-s

Claims (2)

Claim 1. A device for double-sided grinding of the ends of cylindrical parts, containing tool spindles with faceplates, a guiding element with a curved working surface, a flexible tape and a drive for moving it, characterized in that, in order to improve the quality of processing of thin parts, it is equipped with intermediate bars mounted between the flexible tape and the periphery of the tool plates equidistant to the guide element installed • the center of curvature of its working surface is located between them. 2. The device according to claim 1, with the exception of the fact that the guide element is made with side openings for supplying coolant. com between the grinding wheels. In the proposed device, this condition is met and an additional run of the part relative to the point of minimum approximation of the grinding wheels by an amount approximately 2 'where d is the diameter of the workpiece. 10 Compliance with this condition will increase the accuracy of the machining in relation to the accuracy with fixed parts. Thus, the zone of loading, unloading and points of minimum convergence of the grinding wheels, 15 rotated at an angle a are interconnected, as in machines according to the known version. j Depending on the specific processing conditions and the dimensions of the parts, it is possible to constructively select the zone for loading parts directly into the grinding zone: 'the manufacturability of diamond tools with a small height of the diamond layer and diamond savings due to the fact that the diamond layer of the wheel wears out almost completely. On basic devices with the use of diamond blades with a wide cutting surface, when the diamonds wear on the intake cone, the circle becomes unsuitable for operation; the possibility of processing parts in the form of rings and disks of large diameters and small height: the ability to automate loading and unloading of parts. The length of the part processing path, as well as 35 during conventional double-sided grinding between tool spindles, is as follows. that when turning the grinding wheels through the angle a, it is selected depending on the removed allowance, the material of the workpieces and other factors. 7 7 40 'The output of parts from the processing zone in known variants was carried out in the ultrasound itself' '/.7. g .. / Щ-7 '7' • 1 Compiled by O.
