Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, and in particular to a side door structure for a CNC machine tool. Background Technology

[0002] A machine tool housing protects the machine tool, providing a sealed cavity to prevent debris, gas, water, and other contaminants generated during operation from escaping. Most CNC machine tools have a side door for observing the machining process and for cleaning the interior. Existing side doors are mostly rotating or removable frames. While these frames allow opening, they require significant space and are inconvenient to disassemble. For machine tools placed close to a wall, rotating side doors require considerable space, which is inconvenient.

[0003] Chinese Patent Publication No. CN213702467U, published on July 16, 2021, discloses an ultra-high-speed, high-precision flat-bed milling and turning composite CNC machine tool. The machine tool includes a main body and is characterized by: a mounting plate on one outer surface of the main body; a dustproof net on one outer surface of the mounting plate; a heat dissipation cylinder on the inner side of the main body; a heat dissipation net on one outer surface of the heat dissipation cylinder; a fixing rod on the inner side of the heat dissipation cylinder; a motor on one outer surface of the fixing rod; a fan on one outer surface of the motor; a rubber plate on the inner outer surface of the main body; a fixing block on the upper outer surface of the rubber plate; a support plate on the upper outer surface of the fixing block; a hydraulic device on one outer surface of the fixing block; and a spring on the outer side of the hydraulic device. A drawback of this invention is that the side door of the CNC machine tool is detachable, making it inconvenient to clean the interior from the side. Utility Model Content

[0004] The present invention aims to overcome the shortcomings of existing rotating side doors, which occupy a large space and are difficult to open, and provides a CNC machine tool side door structure that can be opened by sliding up and down.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A side door structure for a CNC machine tool, comprising:

[0007] The machine tool body is provided with an observation hole;

[0008] A sliding window, wherein the sliding window is placed inside and matches the observation hole;

[0010] The sliding window is slidably connected with the machine tool body through the cladding frame, the cladding frame is provided with a buckle assembly, and the upper end of the machine tool body is provided with a fixed plate.

[0011] The machine tool body is used for machining the main structure, and an observation hole is formed in the side of the machine tool body for observation and cleaning of the inside of the machine tool.

[0012] Preferably, the observation hole is provided with sliding grooves on both sides, and the upper end of the observation hole is provided with a through hole penetrating the machine tool body and corresponding to the sliding grooves.

[0013] Preferably, the front end of the cladding frame is provided with a reinforcing plate, the cross section of the reinforcing plate is in the shape of a trapezoid, and the upper end of the reinforcing plate is provided with a lifting plate.

[0014] As preferred, the buckle assembly comprises a connecting plate, an elastic plate and a buckling plate, one end of the connecting plate is connected with the upper end of the reinforcing plate, the upper end of the connecting plate is connected with one end of the elastic plate, the angle between the plane where the elastic plate is located and the plane where the connecting plate is located is an obtuse angle, the other end of the elastic plate is connected with the buckling plate, and the buckling plate corresponds to the fixed plate. In order to fix the sliding window at the upper end to prevent it from falling down naturally, the buckle assembly is installed on the reinforcing plate, the connecting plate of the buckle assembly is connected with the reinforcing plate, and then the elastic plate and the buckling plate are connected, the obtuse angle is formed between the elastic plate and the connecting plate, the elastic plate is inclined outward, the buckling plate can be better matched with the fixed plate, the existence of the elastic plate can be deformed, the buckling plate is slid along the fixed plate to be buckled with the fixed plate, the existence of the elastic plate is beneficial to the connection between the buckling plate and the fixed plate, and the position of the cladding frame can be fixed.

[0015] As preferred, the buckling plate is provided with a pull plate, the pull plate is arranged at the connection between the buckling plate and the elastic plate, one end of the pull plate is attached to the buckling plate, and the other end of the pull plate is attached to the elastic plate. When the cladding frame needs to be pulled down, the elastic plate is deformed by pulling the pull plate, the buckling plate is driven away from the fixed plate by the deformation of the elastic plate, the fixing of the cladding frame is released, and the observation hole is closed. This design is convenient for releasing the fixing.

[0016] As preferred, the lower end of the observation hole is provided with a falling groove, the falling groove corresponds to the sliding window, and a buffer pad is installed in the falling groove. When the cladding frame carrying the sliding window falls down, the lower end will hit the machine tool body, and if the operator accidentally loosens, the cladding frame will hit the machine tool body quickly and cause damage to the sliding window. Therefore, the falling groove is arranged at the lower end of the observation hole, and the buffer pad is installed in the falling groove for buffering. The cladding frame carrying the sliding window falls into the falling groove and contacts the buffer pad, so as to prevent damage to the device. This design can buffer the impact on the machine tool body.
