Description

Technical Field

[0001] This utility model relates to the field of milling machine support structure technology, specifically a rotary support mechanism for a double-milling head machine tool used in mold steel processing. Background Technology

[0002] Die steel is a type of steel used to manufacture molds such as cold stamping dies, hot forging dies, and die casting molds. Molds are the main processing tools for manufacturing parts in industries such as machinery manufacturing, radio instruments, motors, and electrical appliances. The quality of the mold directly affects the quality of the pressure processing, the precision and output of the product, and the production cost. In addition to reasonable structural design and machining accuracy, the quality and service life of the mold are mainly affected by the mold material and heat treatment.

[0003] When machining the sides of mold steel, a double-head milling machine is typically used to grind both sides simultaneously. The mold steel is supported on a support turntable mechanism, and its upper end is pressed by a press head. In some cases, the press head of the double-head milling machine can rotate, causing the mold steel to rotate 90° to machine the other two sides. Currently, the support turntable mechanism generally uses a thrust bearing to support the tray. However, due to gaps at the bottom, debris easily enters the bearing at the lower end of the turntable during mold steel machining, affecting its service life. Therefore, an improved technology is urgently needed to solve this problem in the existing technology. Utility Model Content

The second thrust bearing 4 is provided on the upper surface of the slide 1, and the bottom end of the second thrust bearing 4 is fastened to the slide 1 with bolts to fix the bottom of the second thrust bearing 4. The second thrust bearing 4 is sleeved around the frustum 5. The rotary table 2 is supported on the upper surface of the first thrust bearing 3, and a first surrounding plate 6 is provided around the rotary table 2, which wraps around the first thrust bearing 3. The outer periphery of the force bearing 3 has an annular plate 7 at the bottom of the first surrounding plate 6. Several reinforcing plates 12 are evenly arranged on the outer surface of the first surrounding plate 6. The bottom of the reinforcing plates 12 is connected to the upper surface of the annular plate 7 to ensure the structural strength between the first surrounding plate 6 and the annular plate 7. The bottom of the annular plate 7 and the first surrounding plate 6 is supported on the upper surface of the second thrust bearing 4. A second surrounding plate 8 is arranged around the annular plate 7 and wraps around the second thrust bearing 4. Two sets of sliders 9 are symmetrically arranged on the lower surface of the slide block 1. The sliders 9 cooperate with the guide rail on the upper surface of the double milling head machine tool to realize the movement of the turntable mechanism. A lead screw and nut pair 11 is arranged on the lower surface of the slide block 1 and located in the middle position through a fixing block 10. The lead screw and nut pair 11 cooperates with the lead screw used by the double milling head machine tool to drive the slide block 1 to move.
