Description

Technical Field

[0001] The utility model relates to the technical field of machine tools, in particular to a milling and turning compound machine tool. Background Art

[0002] A milling-turning machine tool is a machine tool that can realize multiple processes such as turning, milling, drilling, tapping, etc. of parts under the same clamping, the same precision and the same program. The milling-turning machine tool realizes the processing of the workpiece through the rotation of the spindle and the movement of the worktable, in conjunction with the cutting of the tool. Milling-turning machine tools are widely used in aerospace, automobile manufacturing, machinery manufacturing, mold manufacturing, medical equipment, precision machinery and other fields.

[0003] The milling-turning machine tool is mainly composed of a bed, a spindle system, a worktable, a tool system, etc. The chuck is a kind of machine tool accessory, which is mainly used for clamping and positioning the workpiece. The chuck has a large clamping force and can clamp larger workpieces and withstand higher cutting forces to ensure the stability of the processing process. However, during the operation of the milling-turning machine tool, the turning and milling operations often produce splashes such as metal debris. If these splashes are not properly protected, they may cause harm to the operator. In order to meet this challenge, some milling-turning machine tools are equipped with protective covers above the chuck, which are designed to effectively prevent metal debris from splashing and ensure operation safety. However, in actual operation, especially when processing large workpieces, the presence of such protective covers may become an obstacle to operation and affect work efficiency. At the same time, such protective covers are usually tightly fixed to the machine bed by bolts during installation. Although this fixing method is stable, when it needs to be disassembled or installed, it is necessary to remove multiple bolts one by one. The process is cumbersome and time-consuming, which undoubtedly increases the difficulty of operation and affects the progress and efficiency of the entire processing process. In view of this, we propose a milling-turning machine tool. Utility Model Content

[0025] See also Figure 1-Figure 5 As shown, a milling and turning compound machine tool comprises a bed 1, a chuck 10 for clamping a workpiece is installed at the front end surface of the bed 1, a detachable fixing seat 11 is provided on the top of the bed 1, a slot 111 is provided at the bottom front end of the fixing seat 11, and two symmetrical strip grooves 113 are provided at the top rear end of the fixing seat 11; a fixing plate 13 is fixed in the strip groove 113, a guide rod 14 is slidably installed at the center of the fixing plate 13, and two opposite ends of the two guide rods 14 are fixed There is a slider 16, and the guide rod 14 is sleeved with a spring 15 for pressing the slider 16. A clamping block 17 is fixed to one end face of the slider 16, and the end of the clamping block 17 is inserted into the slot 111; a protective cover 2 is provided above the chuck 10, and the front end face of the protective cover 2 is open, and a plug plate 22 is fixed to the rear end face of the protective cover 2, and the plug plate 22 is plugged into and matched with the slot 111, and both side walls of the plug plate 22 are provided with clamping grooves 221 at the rear end, and the clamping block 17 is clamped into and matched with the clamping grooves 221.

[0026] In this embodiment, grooves are provided at the top center and both sides of the protective cover 2, and transparent observation panels 20 are installed in the grooves. This design is conducive to the operator to clearly observe the processing process without affecting the protective effect. It improves the safety and convenience of operation and reduces the possible operation errors caused by the inability to directly observe.

[0027] In this embodiment, both sides of the slot 111 are provided with plug holes 112, and both sides of the plug plate 22 are fixed with plug rods 21, and the plug rods 21 are plugged into and matched with the plug holes 112. This design makes the installation and removal of the protective cover 2 simple and quick. This design reduces the workload during the disassembly process and improves the processing efficiency.

[0028] In this embodiment, the cross-sectional shape of the protective cover 2 is arched, and the protective cover 2 is made of aluminum alloy. The arched cross-sectional design increases its structural strength, enabling it to withstand greater external impact. The aluminum alloy material is not only light, but also has good corrosion resistance and durability, which prolongs the service life of the protective cover.

[0029] In this embodiment, mounting plates 12 are installed at both left and right ends of the fixing seat 11, and two mounting holes 121 are provided on the mounting plates 12, and connecting bolts threadedly connected to the bed 1 are passed through the mounting holes 121.
