Description

Technical Field

[0001] This utility model relates to the field of CNC machine tools, and in particular to a protective mechanism for CNC machine tools. Background Technology

[0002] A CNC machine tool is an automated machine tool equipped with a program control system. This control system can logically process programs with control codes or other symbolic instructions, decode them, represent them with coded numbers, and input them into the CNC device via an information carrier. After processing, the CNC device sends out various control signals to control the machine tool's movements, automatically machining parts according to the shape and dimensions required by the drawings.

[0003] In the existing technology, some CNC machine tools are equipped with protective mechanisms to prevent the chips generated during the processing of products from flying to the outside. However, the opening and closing of the protective mechanisms are mostly done manually, which is cumbersome, inefficient and requires additional human resources. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies where opening and closing are mostly done manually, and to propose a CNC machine tool protection mechanism.

[0005] To address the problems existing in the prior art, the present invention adopts the following technical solution:

[0006] A protective mechanism for a CNC machine tool includes a worktable, a cover fixedly mounted on the worktable, a top plate on the cover, a pair of fixed plates fixedly mounted inside the cover, each fixed plate having an elongated hole and an arc-shaped hole, a pair of connecting plates between the pair of fixed plates, each connecting plate having a pair of round blocks fixedly mounted on it, the two pairs of round blocks being movably connected to the pair of elongated holes respectively, and a transmission assembly inside the cover, the transmission assembly including a pair of rotating plates, a pair of connecting plates, a round rod, and a motor.

[0007] Preferably, a pair of rotating plates are rotatably mounted on a pair of fixed plates, a pair of connecting plates are rotatably mounted at the ends of the pair of rotating plates, a round rod is fixedly mounted between the connecting plates, a motor is fixedly mounted on the cover, and the motor output shaft is fixedly connected to the end of one rotating plate.

[0008] Preferably, a fixed box is fixedly provided on the workbench, a suction fan is fixedly provided inside the fixed box, a filter box is fixedly provided inside the fixed box, a connecting pipe is fixedly provided on the filter box, and the connecting pipe is fixedly connected to the cover.

[0009] Preferably, the filter box has a first chamber and a second chamber, and a filter plate is fixedly installed inside the filter box.

[0010] Preferably, the connecting pipe connects the first chamber and the cover.

[0011] Preferably, the fixing box has multiple ventilation holes, and the top plate has multiple connecting holes.

[0012] Preferably, a glass plate is fixedly provided on the cover.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, a rotating plate drives a connecting plate to move, a connecting plate drives another connecting plate to move via a round rod, a pair of connecting plates drive a pair of connecting plates to move, and the connecting plate moves upward along the elongated hole under the constraint of the round block. When the upper round block moves to the top of the elongated hole, the connecting plate drives the connecting plate to rotate, and the lower round block enters the arc-shaped hole from the elongated hole until the lower round block moves to the top of the arc-shaped hole, and the connecting plate moves to a position perpendicular to the original position. During this process, the connecting plate first drives the top plate to move upward, so that the top plate is separated from the cover, and then the connecting plate drives the top plate to rotate until it is perpendicular to the original position, thus realizing the automatic opening and closing of the cover.

[0015] 2. In this utility model, the suction fan draws air into the filter box, causing the connecting pipe to draw air into the cover. This not only cools the inside of the cover but also absorbs the debris generated during the processing of the cover. The debris enters the filter box and is blocked by the filter plate, remaining in the first chamber for centralized collection. Attached Figure Description
