Description

Technical Field

[0001] The utility model relates to a numerically controlled machine tool, in particular to a tool chip pushing device for the numerically controlled machine tool. Background Art

[0002] During the processing of CNC machine tools, when the turning tool is cutting the workpiece, due to the feed amount, workpiece material, tool, etc., iron chips (or chips of other materials) often get entangled on the tool. When the tool is entangled with iron chips, the iron chips entangled on the tool will rub against the workpiece violently under the high-speed rotation of the workpiece during processing, causing scratches on the workpiece at the least, and causing the workpiece to be scrapped at the worst. At present, if iron chips are entangled on the tool in the factory, if it is found during the processing, the machine tool is controlled to stop and the iron chips are removed. When removing, the operator manually removes them or uses tools such as hooks to remove them. Direct removal by hand can easily cause injuries to the hands. Using tools such as hooks to remove them is more troublesome, and it is more difficult to remove them when they are tightly entangled, which is inefficient. To this end, a tool chip pushing device for CNC machine tools is proposed. Utility Model Content

[0015] Hereinafter, we will further explain the tool chip pushing device for a CNC machine tool described in the utility model in conjunction with the accompanying drawings.

[0016] It should be noted that all directional indications such as up, down, left, right, front, back... in the embodiments of the utility model are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture as shown in the accompanying drawings. If the specific posture changes, the directional indication will also change accordingly.

[0017] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation" and the like shall be used in a broad sense. For example, "fixation" may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be a direct connection or an indirect connection through an intermediate medium; it may be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example 1

[0018] See also Figure 1-2As shown in the figure, a tool chip pushing device for a CNC machine tool comprises a tool holder 1 and a tool 2 mounted on the tool holder 1; it is characterized in that it also comprises a pushing mechanism 3 mounted on the tool holder 1 for pushing off the chips wrapped around the tool 2, the pushing mechanism 3 comprising a pusher 31 mounted on the tool holder 1 and a pushing member 32 mounted on the pusher 31;

[0019] By setting the pushing mechanism 3, the iron chips or other material chips wrapped around the tool 2 can be automatically pushed off the tool 2 during the processing or after the processing is completed, so as to avoid the iron chips being wrapped around the tool 2 and causing damage to the workpiece, resulting in the scrapping of the workpiece;

[0020] At the same time, there is no need to manually remove iron chips, which is highly efficient. During the processing, there is no need to stop the machine for manual chip removal, and it can also avoid being injured by iron chips during manual chip removal.

[0021] In one embodiment, it also includes a pushing frame 33 installed on the tool holder 1, and the pusher 31 is installed on the pushing frame 33; the pushing member 32 is provided with an avoidance groove 4 adapted to the tool 2; the avoidance groove 4 is set to avoid interference between the pushing member 32 and the tool 2, and at the same time, the pushing member 32 is placed around the tool 2, so that the shavings wrapped around the tool 2 can be pushed down more easily.

[0022] In one embodiment, the pushing frame 33 is installed behind the tool holder 1, and one end of the pushing member 32 is connected to the pusher 31, and the other end passes through the tool holder 1 and forms a double plate on both sides of the tool 2 through the setting of the avoidance groove 4; the pushing member 32 forms a double plate on both sides of the tool 2 through the avoidance groove 4. When the crumbs are pushed by the pushing member 32, the pushing member 32 simultaneously forms a thrust on both sides of the crumbs, avoiding the crumbs from being subjected to a unilateral thrust, causing them to tilt after being subjected to the force, and the force is applied to the tool 2, which is difficult to remove and causes damage to the tool 2.

[0023] The pusher 31 can be any one of a cylinder, an electric push rod, and an electromagnet pusher 31. Example 2
