Hot-blast stove column one-time clamping turning clamping device

Abstract

The invention relates to a hot-blast stove column one-time clamping turning clamping device. The hot-blast stove column one-time clamping turning clamping device comprises a supporting rod (3), a first disc (4), a second disc (9) and a weight (10); the first disc (4) and the second disc (9) are arranged on the supporting rod (3) in a sleeving mode; the supporting rod (3) is provided with positioning holes (31) in the radial direction, an axial positioning device is arranged on the supporting rod (3), the weight (10) can penetrate through the positioning holes (31), and the left side of the weight (10) can be in contact connection with the axial positioning device; and the right side walls of the first disc (4) and the second disc (9) are provided with radial positioning devices. Accordingto the hot-blast stove column one-time clamping turning clamping device, the weight (10) and the two ends are pressed on an opening of one side of a stove column through the axial positioning device,axial fixing is achieved, in addition, the hot-blast stove column one-time clamping turning clamping device and the stove column are fixed in the radial direction through the radial positioning devices, and thus, the clamping alignment function of a machining lathe is easy to achieve; and all surfaces are clamped and machined at a time, the form and position error is small, and the problems that an existing stove column is difficult to clamp and disassemble, the number of times of clamping is large, procedures are large, and the machining efficiency is low are solved.

Description

technical field [0001] The invention relates to a one-time clamping and turning clamping device for a furnace column of a hot blast stove, which belongs to the field of metallurgical equipment manufacturing. Background technique [0002] Furnace column is the supporting part of furnace grate of blast furnace hot blast stove. It is a cast hollow cylindrical part. The two ends of the cylinder body are cast into four long grooves at 90° along the outer circle. This structure has the function of reducing weight and ventilation. The inner opening at the upper end is trumpet-shaped, and the inner opening at the lower end is a flange structure. The outer end plane, upper end plane, outer circle and inner cone of the lower flange need to be processed. Due to the large diameter of the furnace column workpiece, the inner and outer walls are rough surfaces and have holes, so it is difficult to clamp. Generally, it needs to be clamped three times for processing, first turning the oute...
