Description

Technical Field

[0001] The utility model belongs to the technical field of machine tool equipment and relates to a turning tool fixture. Background Art

[0002] The tool rest is an important part of the machine tool for placing tools, including turret tool rests, square tool rests, etc. The turret tool rest is a commonly used tool rest mechanism on CNC machine tools. Several tools are installed on the turret tool rest, and the tools can be automatically switched according to the needs of processing. The turret tool rest is referred to as the turret, which is installed and fixed on the saddle of the machine tool, and the saddle is installed on the bed of the machine tool.

[0003] In order to realize the modular production of the saddle and turret assembly during the assembly of the machine tool, engineers designed a special assembly fixture, such as a turning frame for machine tool assembly proposed in Chinese patent literature [application number: CN201921576824.8; announcement number: CN 210589142U], which includes a base frame, a rotatable fixed frame for fixing the saddle is provided on the base frame, a horizontally placed support shaft is detachably fixed on the base frame, the right end of the fixed frame is hinged on the base frame, the left end of the fixed frame is supported on the support shaft, a support frame is fixedly connected to the base frame on the left side of the support shaft, and a support bolt capable of supporting the saddle is threadedly connected to the upper end of the support frame. When using the turning frame to assemble the saddle and turret, first fix the support shaft to the base frame, support the left end of the fixed frame on the support shaft, then fix the saddle to the fixed frame, and then remove the support shaft from the base frame. After the fixed frame loses the support of the support shaft, rotate downward around the hinge between the fixed frame and the base frame until the saddle is supported on the support bolts, and then rotate the support bolts to make the mounting surface of the turret on the saddle horizontal. Then fix the turret on the saddle, and after the turret and the saddle are modularly connected, rotate the fixed frame upward, re-fix the support shaft on the base frame, and support the fixed frame on the support shaft again. Move the assembly of the turret and the saddle to the bed of the machine tool for assembly, and install the next set of saddles and turrets on the turning frame. The above-mentioned turning frame for machine tool assembly is suitable for the assembly of single-track saddles and turrets.

[0004] With the development of the manufacturing industry, CNC machine tools as production equipment are also constantly upgraded. For example, on the basis of the traditional horizontal lathe, the addition of a Y-axis to the turret can greatly improve the range and accuracy of processing. In this way, it is necessary to develop the single-line rail saddle into a double-line rail saddle. The double-line rail saddle has a slide plate mounting surface and a turret mounting surface facing different directions. During assembly, the linear rail and the slide plate need to be installed on the slide plate mounting surface (the other linear rail is installed on the slide plate), and the turret is installed on the turret mounting surface. The above-mentioned turning frame for machine tool assembly can no longer meet the assembly requirements of the double-line rail saddle, and engineers need to redesign a special tooling fixture suitable for the assembly of the double-line rail saddle, that is, to design a special tooling fixture so that the saddle can be assembled with both the turret and the slide plate.
