[0002] The main functions of CNC machine tool protective covers include protecting precision components such as machine tool guideways and lead screws from corrosion by chips and cutting fluid, extending equipment life, isolating high-speed moving parts, preventing operators from touching them and causing mechanical injury, blocking debris splashed during processing, maintaining a clean workshop environment, and some protective covers can also reduce noise and improve the safety and reliability of machine tool operation.

[0003] In the current technology, when operators manually open the protective cover of a CNC machine tool, if they want to open the door from the middle to the sides, they need to swing the cover door to both sides. This method can easily damage the internal parts of the machine tool. Therefore, most manual opening methods involve opening one side of the cover door first, then walking to the other side, and then pulling open the other side's cover door. Because this method requires the operator to move frequently, it reduces work efficiency. Therefore, a CNC machine tool protective cover that is easy to open and close is proposed to solve the above problems. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figures 1-3 This utility model provides an embodiment of a conveniently opening and closing CNC machine tool protective cover, comprising a body 1 for supporting the overall device and a cover door 4 for enclosing the space. Extension plates 2 for supporting limiting rods 3 are fixedly connected to both ends of the upper surface of the body 1. Limiting rods 3 for restricting the movement of the cover door 4 are fixedly connected to opposite sides of the two sets of extension plates 2. The outer wall of the limiting rod 3 is slidably connected to the inner wall of the cover door 4. A locking assembly 6 for fixing the cover door 4 is provided on the lower inner wall of the cover door 4. A linkage assembly 7 for linking the movement of the two cover doors 4 is provided on the lower surface of the body 1. The linkage assembly 7 includes a slide groove 71 for supporting the sliding of a slider 72. The slide groove 71 is opened on the lower surface of the body 1. A slider 72 for supporting a support rod 73 is slidably connected to the inner wall of the slide groove 71. A support rod 73 for supporting a swing rod 74 is fixedly connected to the lower surface of the slider 72.

[0031] Reference Figures 2-4Two sets of swing rods 74 are rotatably connected to the outer wall of the support rod 73 to connect the support rod 73 and the connecting rod 75. The upper surface of the swing rod 74 is rotatably connected to the front part of the upper surface of the connecting rod 74 to the door 4. The upper surface of the connecting rod 75 is rotatably connected to the lower surface of the door 4. A limiting plate 78 is fixedly connected to the lower part of the front surface of the body 1 to restrict the movement of the connecting rod 75. The outer wall of the connecting rod 75 is slidably connected to the inner wall of the limiting plate 78. The lower surface of the door 4 is fixedly connected to the left and right ends of the door to support the rollers 77. The support base 76 has rollers 77 installed at both the front and rear ends of its lower surface for moving the door 4. The upper surface of the limiting plate 78 has a receiving groove 79 for the rollers 77 to move. The front surface of the door 4 is fixedly connected to a handle 5 for the operator to move the door 4. The limiting plate 78 is H-shaped, so that the limiting plate 78 can restrict the movement of the connecting rod 75 while allowing the insertion rod 63 to pass through. The slider 72 is H-shaped and the slide groove 71 is T-shaped. The slider 72 and the slide groove 71 slide in a sliding fit, so that the connection between the slider 72 and the slide groove 71 is tighter.

[0032] Reference Figures 2-4 The locking assembly 6 includes a pedal 61 for the operator to step on to facilitate the movement of the insertion rod 63. The upper surface of the pedal 61 is provided with anti-slip texture 62 to increase the friction between the shoe and the pedal 61. The middle of the upper surface of the pedal 61 is fixedly connected to the insertion rod 63 for inserting into the door 4 to fix the door 4. The outer wall of the insertion rod 63 penetrates and is slidably connected to the middle inner wall of the limiting plate 78. The upper part of the outer wall of the insertion rod 63 is inserted into the inner wall of the door 4. The upper surface of the insertion rod 63 is set as a slope. When the slope is squeezed, it drives the insertion rod 63 to move downward, realizing the automatic locking of the insertion rod 63 to the door 4. The pedal 61 and the limiting plate 78 are elastically connected by a support spring 64. The support spring 64 uses its own elastic force to force the insertion rod 63 and insert it into the door 4, maintaining the insertion of the insertion rod 63.

[0033] Working principle: When the operator needs to manually open the door 4, first step down on the pedal 61. The downward movement of the pedal 61 causes the insertion rod 63 to move downward and disengage from the door 4, releasing the limit on the door 4. At this time, the support spring 64 is stretched. Then, grasp the handle 5 and pull the door 4 to the right until it moves to the position where it is disengaged from the insertion rod 63. Then release the pedal 61. The insertion rod 63 returns to its original position under the action of the support spring 64. During the movement, the door 4 moves along the limit rod 3. When the door 4 moves, it causes the connecting rod 75 to move. During the movement of the connecting rod 75, the connecting rod 75 rotates through the connection with the door 4, causing the slider 72 on the swing rod 74 to slide forward synchronously on the inner wall of the slide groove 71, thereby causing the other set of swing rods 74 to move synchronously, so that the two sets of door 4 can be opened synchronously.

[0034] When the door 4 moves, the bottom roller 77 assists the door 4 in moving, making the movement of the door 4 smoother. At the same time, because the roller 77 rolls inside the receiving groove 79, it also restricts the movement of the door 4 below.

[0035] When it is necessary to close the door 4, simply pull the door 4 towards the center. When the door 4 contacts the insertion rod 63, it will press the sloping part of the insertion rod 63, causing the insertion rod 63 to move downward. Then, under the action of the support spring 64, it will be reinserted into the door 4. This process does not require the operator to step on the pedal 61 a second time.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
