Description

Technical Field

[0001] The invention relates to the technical field of mechanical equipment, and in particular to a dual-spindle turning and milling processing device. Background Art

[0002] CNC lathe is one of the most widely used CNC machine tools. It is mainly used for cutting inner and outer cylindrical surfaces of shaft parts or disk parts, inner and outer conical surfaces of arbitrary taper angles, complex rotational inner and outer curved surfaces, cylindrical and conical threads, etc., and can perform grooving, drilling, reaming, reaming and boring. However, the current CNC lathe auxiliary worktable has few tool positions and cannot meet the increasingly complex milling needs, and the processing range is limited. In addition, the turret has poor stability when raising and lowering the milling position, and the spindle slide and the milling cutter slide are difficult to move relative to each other, which is easily restricted when processing workpieces of different specifications.

[0003] In order to solve the deficiencies of the prior art, people have conducted long-term exploration and proposed various solutions. For example, a Chinese patent document discloses a milling structure of a dual-spindle dual-table CNC lathe [CN202221827306.0], which includes a bed and a main spindle, the main spindle is arranged on one side of the upper surface of the body, a Y-axis transmission member is arranged on the rear side of the main spindle, a bidirectional power head is arranged on the transmission shaft of the Y-axis transmission member, a first Z-axis transmission member is arranged on the lower side of the bidirectional power head, a sub-table is arranged on the front side of the main spindle away from the bidirectional power head, a turret is arranged on the upper side of the sub-table, an X-axis transmission member is arranged on the side of the upper surface of the bed away from the sub-table, a second Z-axis transmission member is arranged on the upper side of the X-axis transmission member, and a sub-spindle is arranged on the upper side of the second Z-axis transmission member.

[0004] The above solution has to some extent solved the problem in the prior art that the CNC lathe auxiliary worktable has few tool positions and cannot meet the increasingly complex milling needs. However, the solution still has many shortcomings, such as: the turret has poor stability when raising and lowering the milling position, and the spindle slide and the milling cutter slide are difficult to move relative to each other, which is easily restricted when processing workpieces of different specifications.
