[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0019] like Figures 1 to 4 The embodiment of the utility model presented preferably provides a protective door for a CNC machine tool, including a machine tool body 1 and a protective door 2, a first guide rail 3 and a second guide rail are respectively provided on the outside of the machine tool body 1, the first guide rail 3 and the second guide rail are coaxially arranged, the protective door 2 is slidingly arranged on the first guide rail 3 and the second guide rail, a baffle 5 is rotatably provided on one side of the machine tool body 1 and located at one end of the first guide rail 3 or the second guide rail, and a connecting component 6 that can drive the baffle 5 to maintain a closed state is provided on the machine tool body 1, and the closed state of the baffle 5 can prevent the protective door 2 from moving away from the first guide rail 3 and the second guide rail.

[0020] Specifically, the protective door is slidably connected to the first guide rail and the second guide rail located on the outside of the machine tool body. When the protective door needs to be disassembled for maintenance or replacement, the protective door can be directly displaced and removed from the ends of the first guide rail and the second guide rail, avoiding the cumbersome disadvantage of having to disassemble the machine tool body shell before disassembling the protective door; and when the protective door is in normal use, it can be limited by the cooperation of the baffle and the connecting component to effectively prevent the protective door from being disassembled and detached, thereby achieving the limiting effect of the normal sliding of the protective door.

[0021] Furthermore, the connecting member 6 includes a spring latch 8 that is disposed on one side of the machine tool body 1 and is relatively elastic and retractable. The baffle 5 has a pin hole 9 that can cooperate with the spring latch 8. When the spring latch 8 is inserted into the pin hole 9, the baffle 5 maintains a closed state that blocks one end of the first guide rail 3 or the second guide rail. Specifically, the spring latch is a relatively mature existing technology, which includes a spring and a pin shaft. A limit groove is formed in the inner recess of one side of the machine tool body. The pin shaft is limited in the limit groove, and one end of the pin shaft can move and protrude outward from the outside of the machine tool body along the depth of the limit groove. The spring is placed in the limit groove and abuts against one end of the pin shaft. The elastic force of the spring drives the pin shaft to maintain one end protruding outward from the limit groove, so that the pin shaft is inserted into the pin hole of the baffle to achieve the fixation of the baffle. When the protective door needs to be removed, the pin shaft is pressed to disengage it from the pin hole, so that the protective door can be displaced axially along the first and second guide rails and disengaged from the ends of the first and second guide rails.

[0022] Furthermore, an upper-opening chip groove 11 is provided on the outer wall of one side of the machine tool body 1. The length direction of the chip groove 11 is parallel to the length direction of the first guide rail 3. One end of the chip groove 11 has a notch 12. The baffle 5 is rotated to cover the notch 12. The lower end of the protective door 2 is accommodated in the chip groove 11 and can slide axially along the first guide rail 3 through the notch 12. Furthermore, by providing the chip groove, waste chips that splash onto the protective door can fall along the inner side wall of the protective door into the chip groove for centralized collection. And by placing the baffle cover on the notch at one end of the chip groove, when the baffle is rotated to disengage from covering the end of the chip groove, the user can scrape and clean the inner cavity of the chip groove, and the waste inside the chip groove can be swept out through the notch. At the same time, it can also meet the requirements of disassembling the protective door from the first and second guide rails.

[0023] Furthermore, a sealing strip capable of abutting against the side wall of the chip removal groove 11 is provided on the peripheral side of the baffle 5 .

[0024] Furthermore, the edge profile of one side of the machine tool body 1 is identical to the cross-sectional profile of the protective door 2, and the protective door 2 covers the corresponding side of the machine tool body 1. The protective door 2 comprises a horizontal section 21, a first vertical section 22, an inclined section 23, and a second vertical section 24, which are sequentially connected. The inclined section 23 is tilted inwardly relative to the first vertical section 22 toward the horizontal section 21, and the angle between the extended line of the inclined section 23 and the extended line of the horizontal section 21 is 0° to 90°. Furthermore, through the combined position limiting of the horizontal and inclined sections, the protective door can effectively achieve upper and lower limit locking relative to the machine tool body.

[0025] Furthermore, the first guide rail 3 is arranged on the upper side of the machine tool body 1, and a limiting groove 25 is provided on one side of the first guide rail 3 along its axial direction. A slider 28 that can cooperate with the first guide rail 3 is provided on the inner side of the protective door 2. The slider 28 can only be movably placed on the first guide rail 3 by the end of the first guide rail 3 and cooperate with the limiting groove 25.

[0026] Furthermore, the second guide rail is located in the chip removal groove 11, and a pulley 26 is provided at the lower end of the protective door 2. The pulley 26 is slidably provided on the second guide rail.

[0027] Furthermore, the protective door 2 is formed by integral bending using a sheet metal process, thereby effectively reducing the production and assembly costs of the protective door.

[0028] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for illustrative purposes. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
