Tool setting tool

Technical Field

The utility model belongs to the technical field of the work piece processing, more specifically say, relate to a tool setting frock.

Background

The single continuous casting machine constituting the continuous casting line in the continuous casting production is generally called a sector section, and is generally divided into an arc section (or a bending section), a straightening section, a horizontal section and the like. According to different casting blanks, the steel can be divided into slab sector, square billet sector, round billet sector, special-shaped billet sector and the like. The most common in production are slab and billet sectors. The work piece of fan-shaped section is influenced by continuous casting billet heat radiation, cooling water spray, hot corrosive gas erosion, casting blank gravity, casting blank pressure etc. factor in the work, and fan-shaped section work piece work is continuous and has not had the intermittence in the continuous casting process, just carries out the change of corresponding work piece and the maintenance of inserting the production line of work piece when corresponding work piece appears unusually or fan-shaped section reaches certain excess steel volume. The sector section has the characteristics of severe working environment and no intermittence in working, so that the sector section needs to be frequently replaced and maintained. The maintenance comprises off-line maintenance and factory precision recovery: the offline maintenance (in an off-inspection workshop on a continuous casting site) is used for replacing a roller set, replacing a nozzle of a cooling system, replacing parts of a lubricating system, performing pressure test, arc correction, calibration and the like, and the above contents only can be used for replacing a simple workpiece and cannot completely recover the precision influence of large workpieces caused by factors such as abrasion and the like. And (4) recovering the precision of the factory (a professional manufacturing factory) to further disassemble the roller set, replace parts such as a bearing, a seal and the like, manufacture the scrapped parts and recover the precision of the fan-shaped section frame. The Chinese patent application numbers are: 200520078968.2, filing date: 2005.06.24 which discloses the construction of a segmental frame.

The fan-shaped section frame is special in structure, the mounting roller set surface is an inclined surface, and the processing, the measurement and the like are all technical difficulties. The inclined surface on the fan-shaped section frame is not parallel to the XZ plane of the machine tool but forms a certain included angle, so that a cutter for processing the inclined surface of the fan-shaped section frame is required to form a certain included angle with the Y axis of the machine tool perpendicular to the inclined surface. The milling head of the machine tool for processing the fan-shaped section frame can deflect a certain angle (meeting the requirement of a drawing); in addition, repeated tool setting and trigonometric function calculation are needed, the process is complex, continuous precision adjustment of the fan-shaped section frame is not facilitated, and precision and efficiency are low.

In the manufacturing process of the tool setting tool, the structural dimension data of the tool setting tool is known. And the tool setting tools 5 on the first pair of tool blocks 1 have five planes A1-A6 (since the plane A3 and the plane A4 are both parallel to the horizontal plane, the plane A3 and the plane A4 share one tool setting tool 5), and the tool setting tools only need to be installed on the fan-shaped section frame once to complete the whole repairing work (finally, the plane A3 and the plane A4 are repaired).

S6, calculating the distance between the center of the tool 9 and the initial surface (the initial surface in this embodiment is a plane formed by a surface A3 and a surface A4) and the Y coordinate of the initial surface to obtain the Y-direction distance between the tool 9 and the original coordinate origin, translating the center of the bottom surface of the tool 9 in the Y direction to combine with the determined zero points in the X direction and the Z direction, marking the center of the bottom surface of the tool 9 as a new rectangular space coordinate zero point, and coinciding the original point of the coordinate system actually used for repairing on the machine tool 8 with the original point of the workpiece coordinate system in this embodiment, so coinciding the original point of the coordinate system actually used for repairing on the machine tool 8 with the original point of the coordinate system of the design drawing.

And S7, as shown in the figures 12 and 13, repairing the plane to be repaired on the segmental frame according to the coordinate system and the corresponding coordinates of the design drawing. And when the plane with the same inclination angle is repaired, the steps S4-S6 are repeated to finish the repairing work of the whole segmental frame.
