specific Embodiment approach 1

[0015] Specific implementation mode one: as Figure 1 to Figure 9 As shown, a kind of processing method of adjusting the inclined block in this embodiment is carried out according to the following steps:

[0016] Step 1: Under the conditions of rotation speed of 500r / min, feed rate of 0.4mm / r, and cutting depth of 2.5mm, turn the outer circle of the blank according to Ф46.3(+0.1 / 0)mm×50.5mm to obtain a cylindrical blank 1, and process the auxiliary head 2 on the lower end surface along the height direction of the cylindrical blank 1 according to Ф20mm×30mm. The auxiliary head 2 is concentric and coaxial with the cylindrical blank 1, and the first center hole 3 is punched on the upper end surface of the cylindrical blank 1. On the auxiliary head 2 The second center hole 4 is drilled on the lower end surface of the lower end surface to obtain the workpiece A to be processed;

[0017] Step 2: Under the condition that the rotation speed is 200r / min, the feed rate is 5mm / r, and th...

Abstract

The invention relates to a machining method of an adjusting oblique block, and aims to solve the problems of high machining cost and long machining period in the conventional adjusting oblique block. The method comprises the following steps: I, turning an outer circle, machining an auxiliary head, and punching a central hole; II, milling to form a flat part; III, performing thermal treatment; IV, accurately grinding the outer circle; V, accurately grinding a flat surface and upper and lower surfaces; VI, machining a boss; VII, forming a U-shaped groove, and drilling holes in upper and lower parts to finish machining of the adjusting oblique block. The machining method is used for manufacturing the adjusting oblique block.

Description

technical field [0001] The invention relates to a processing method for adjusting an inclined block. Background technique [0002] Adjusting the inclined block is an important part of the eccentricity gauge of the steam turbine tooling. Due to the complex structure and irregular shape of this part, the high accuracy of the molded line, the dimensional accuracy is 0.02mm, and the symmetry of the molded line is 0.04mm, so the manufacturing cost is high and the processing cycle is long. . Contents of the invention [0003] The present invention aims to solve the problems of high processing cost and long processing period of the existing adjusting slanting block, and provides a processing method for adjusting the slanting block. [0004] A kind of processing method of adjusting the inclined block of the present invention is to carry out according to the following steps: [0005] Step 1: Under the conditions of rotation speed of 500r / min, feed rate of 0.4mm / r, and cutting dep...
