Profiling grinding wheel dressing device for surface grinder

Abstract

The invention discloses a profiling grinding wheel dressing device for a surface grinder. The profiling grinding wheel dressing device comprises a base, a mould plate and a movable tool carrier; one end of the base is provided with a hand-wheel assembly while the other end is fixedly connected with the mould plate; the base and the upper table-board of the mould plate are provided with the movable tool carrier; one end of the tool carrier is provided with a horizontal through hole, an end face of the through hole is fixed with a nut, the centre of the movable tool carrier is provided with a vertical positioning hole, an upper end face of the vertical positioning hole is fixedly equipped with a guiding sleeve, an elastic guide rod assembly is arranged in the vertical positioning hole, and a guide rod on the elastic guide rod assembly upwards extends out of the guide sleeve, the extending part of the guide rod is sleeved with a fixing sleeve in which a diamond cutter is arranged, the diamond cutter is coaxial with the guide rod, an upper end face of the diamond cutter extends out of the fixing sleeve, and a lower end face of the diamond cutter is propped against the upper end face of the guide rod. The profiling grinding wheel dressing device provided by the invention can enable the diamond cutter to finish the profiling action to dress the profile of the grinding wheel; and thestructure is simple and the operation is convenient.

Description

Technical field [0001] The invention belongs to the technical field of mechanical equipment and relates to a profiling grinding wheel dressing device for a surface grinder. Background technique [0002] In the manufacturing process of steel rolling machinery, parts of the camber backing plate type are often encountered. Common cambered backing plates have a single arc surface, multiple arc surfaces connected, and arc surfaces and inclined surfaces. And so on, such as Figure 5 Disclosed is a cambered cushion 13 in the assembly of the lower support roll of a cold rolling mill. The top surface of the cambered cushion 13 is formed by a combination of a circular arc surface R and an inclined surface A, and the two inclined surfaces are tangent to the circular arc surface and are relatively round. The arc surface is symmetrical, thus forming a chamfered arc surface, and its surface finish is required to reach Ra1.6. For setting the above-mentioned backing plate with a beveled arc surf...
