Detailed Description
As shown in fig. 1-3, a fixture for processing an inclined plane at the upper end of an eight-section type structural ring rail comprises eight clamping tools, each clamping tool comprises a base 1, four supporting blocks 2 and four puller bolts 3, the supporting blocks 2 are respectively symmetrically arranged at four corners of the base 1, the supporting blocks 2 are provided with screw holes, and the puller bolts 3 are screwed into the screw holes; the front end of the puller bolt 3 is a pointed end, and a steel ball is embedded in the end part of the pointed end; two mounting grooves 4 are symmetrically arranged on the base 1.
As shown in fig. 4 and 5, the two ends of the arc-shaped member 5 of the eight-segment type structure circular rail are oblique joint surfaces 9, and the upper end of the arc-shaped member needs to be processed into an inclined surface 8.
The processing process is as follows: as shown in fig. 6, eight clamping tools are placed on a lathe workbench 6, a T-shaped block is placed in a T-shaped groove 7 of the lathe workbench 6, a pressure plate is pressed on a base 1 by a pressure bolt and is screwed with the T-shaped block, and a screw rod of the pressure bolt is positioned in an installation groove 4 and is tightly clamped at the innermost end of the installation groove 4, so that the clamping tools are fixed on the lathe workbench 6; eight arc-shaped pieces 5 of the eight-section type structural ring rail form a circular ring and are placed on an eight-piece clamping tool, oblique joint surfaces 9 of two adjacent arc-shaped pieces 5 are attached together, the oblique joint surfaces 9 are positioned at the central positions of four supporting blocks 2 of the clamping tool, and four puller bolts 3 are screwed in to clamp the arc-shaped pieces 5; and starting the lathe to process the upper end surface of the eight-section type structure ring rail into the inclined surface 8.
