Description

Technical Field

[0001] The utility model relates to the technical field of machine tool equipment, and particularly relates to a milling and grinding machine tool with a protection mechanism. Background Art

[0002] A milling and grinding machine tool mainly refers to a machine tool that processes various surfaces of a workpiece with a milling cutter. Usually, the rotational movement of the milling cutter is the main movement, and the movement of the workpiece and the milling cutter is the feed movement. It can machine planes, grooves, and can also machine various curved surfaces, gears, etc. A milling and grinding machine tool is a machine tool that mills a workpiece with a milling cutter. Since traditional milling and grinding machine tools are convenient for clamping workpieces and tools, the milling cutter spindle and the slide table are both in an exposed state, which makes the workpiece somewhat dangerous during the processing. For example, when the feed rate is too large, the workpiece may become loose or the tool may break, resulting in the workpiece and the broken tool flying out and causing an accident. In addition, when there are defects in the fixture and the tool, it will also cause the workpiece and the broken tool to fly out and injure people. Therefore, it is necessary to install a set of accessories on existing milling machines, grinding machines and other equipment to provide safety protection capabilities. Content of the Utility Model

[0008] Preferably, on the top of the annular base and the bottom of the fixed ring, alignment tracks for cooperating with the rear cover are respectively provided circumferentially. The rear cover cooperates with the corresponding alignment tracks through the top and the bottom, and the tops on both sides of the annular base are respectively fixedly connected with the bottom of the fixed ring through vertically arranged support columns.

[0009] The beneficial effects of the present utility model are as follows: The movable cover can be pushed and pulled and slid in the lower ring rail, so as to form an enclosed structure with the rear cover, realizing the protection of the workpiece and the tool during the processing process, and avoiding the safety production accidents caused by the direct flying out of the workpiece and tool fragments from the workbench. The fixed ring restricts the tops of the rear cover and the movable cover, thereby improving the stability and protection strength of the two, while the shielding ring provides a certain degree of protection for the area above the rear cover and the movable cover. The floating cover is connected to the axle box through a flexible sleeve, so as to meet the protection requirements after the spindle angle is adjusted. When the worker processes the workpiece, the cutting fluid flowing in the lower ring rail automatically closes the movable cover. The support columns improve the stability of the fixed ring and limit the vertical distance between the fixed ring and the annular base, thereby ensuring the working stability of the movable cover and the rear cover.

[0017] According to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, a milling and grinding machine tool with a protection mechanism includes a milling machine body. A workbench 1 is provided on the milling machine body, and an axle box 2 corresponding to the upper part of the workbench 1, which includes: an annular base 3, the annular base 3 is fixedly arranged on the workbench 1, and a lower ring rail 4 is provided circumferentially on the top of the annular base 3; a rear cover 5, the rear cover 5 is a semi-circular transparent tube sheet structure, the rear cover 5 is vertically connected to the top of the annular base 3, and the rear cover 5 and the annular base 3 are coaxially set; a movable cover 6, the movable cover 6 is a semi-circular transparent tube sheet structure, the movable cover 6 is vertically arranged on the top of the annular base 3 and is coaxially set with the annular base 3, and the bottom of the movable cover 6 is slidably matched with the lower ring rail 4; a handle 7 is provided on the outer side wall of the movable cover 6.

[0018] Through the above settings, the worker pushes and pulls the movable cover 6 through the handle 7 to make it slide in the lower ring rail 4, so as to form an enclosed structure with the rear cover 5, realizing the protection of the workpiece and the tool during the processing process, and avoiding safety production accidents caused by the direct flying out of the workpiece and tool fragments from the workbench 1. Among them, the movable cover 6 can be made of all-acrylic, or lightweight protective net, or a combination of plate and glass, plate and protective net, and has the characteristics of sufficient impact resistance, light weight and easy movement.

[0019] A fixing ring 8 is provided on the top of the rear cover 5 corresponding to the annular base 3, an upper ring rail 9 is provided on the bottom of the fixing ring 8 corresponding to the lower ring rail 4, and the top of the movable cover 6 is slidably matched with the upper ring rail 9; a shielding ring 10 extending horizontally towards the center is provided on the bottom of the fixing ring 8, and the inner edge of the shielding ring 10 is spaced from the outer side wall of the axle box 2.

[0020] With this setting, the fixed ring 8 restricts the top of the rear cover 5 and the movable cover 6, thereby improving the stability and protection strength of both. The shielding ring 10 provides a certain degree of protection for the areas above the rear cover 5 and the movable cover 6.

[0021] It further includes a floating cover 11 provided at the top of the shielding ring 10. A round hole is provided in the center of the floating cover 11, and the round hole is connected to the outer side wall of the axle box 2 through a flexible sleeve 12.

[0022] With this setting, the floating cover 11 is connected to the axle box 2 through the flexible sleeve 12, so as to meet the protection requirements after the main shaft angle is adjusted.
