Description

Technical Field

[0001] The utility model belongs to the technical field of machine tool guide rail protective covers, in particular to a novel telescopic machine tool guide rail protective cover. Background Art

[0002] CNC lathe is one of the most widely used CNC machine tools at present. It is mainly used for cutting inner and outer cylindrical surfaces of shaft parts or disk parts, inner and outer conical surfaces of arbitrary taper angles, complex rotating inner and outer curved surfaces, and cylindrical and conical threads, and can perform grooving, drilling, reaming, reaming and boring, etc.

[0003] After searching, the Chinese utility model patent with authorization announcement number: CN212794188U discloses a telescopic protective cover for machine tools. Although the above device covers the internal screw, guide rails and other components of the machine tool through the first protective cover, the second protective cover, the third protective cover, the fourth protective cover, the fifth protective cover and the sixth protective cover, after the telescopic cover covers the multiple protective covers, the waste chips generated by cutting will fall into the gap of the telescopic cover, resulting in inconvenience in cleaning. At the same time, with continuous extension and retraction, the waste chips may puncture the protective cover, resulting in a decrease in the protection performance of the guide rails, affecting the service life of the machine tool.

[0004] To this end, we proposed a new type of telescopic machine tool guide rail protective cover to solve the above problems. Utility Model Content

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0022] Reference Figure 1-Figure 3 A novel telescopic machine tool guide rail protective cover comprises a first protective cover 1, one side of the first protective cover 1 is fixedly connected with a fixing plate 7, a second protective cover 2 is slidably embedded in the first protective cover 1 on the side facing away from the fixing plate 7, a third protective cover 3 is slidably embedded in the inner side of the second protective cover 2 away from the first protective cover 1, a fourth protective cover 4 is slidably embedded in the inner side of the third protective cover 3 away from the second protective cover 2, a fifth protective cover 5 is slidably embedded in the inner side of the fourth protective cover 4 away from the third protective cover 3, a connecting plate 6 is fixedly connected to the fifth protective cover 5 away from the fixing plate 7, and the first protective cover 1 is connected to the second protective cover 2. A cleaning piece is provided on the adjacent side for cleaning the surface of the second protective cover 2 as the first protective cover 1 moves. Not only is there a cleaning piece between the first dust cover and the second dust cover, but also a cleaning piece is provided at one end close to the inner side between each adjacent layer of protective covers, and a connecting piece is provided on the side of the vertical end where the first protective cover 1 and the second protective cover 2 are attached to each other for keeping the second protective cover 2 sliding smoothly along the first protective cover 1. Similarly, a connecting piece is provided on the inner wall close to the vertical end between each adjacent layer of protective covers. By shrinking the adjacent layers of protective covers, the surface of the inner protective cover can be cleaned, which improves the cleaning convenience of the protective cover and at the same time improves the service life of the internal guide rail.

[0023] Reference Figure 4 The cleaning part includes a cleaning inclined plate 9 fixedly connected to one end of the first protective cover 1, and the cleaning inclined plate 9 is in close contact with the top surface of the second protective cover 2. When the first protective cover 1 retracts the second layer, the cleaning inclined plate 9 on one side of the first protective cover 1 pushes the waste on the surface of the second layer of protective cover to clean and pile them together for centralized treatment.

[0024] Reference Figure 5 The connecting part includes a T-shaped slider 11 fixedly connected to the inner side of the first protective cover 1, and a T-shaped slide groove 10 matched with the T-shaped slider 11 is provided on the outer side of the second protective cover 2. The first protective cover 1 and the second protective cover 2, etc., the vertical ends of the two adjacent inner sides of the multi-layer protective cover are provided with T-row sliders, and the outer vertical ends of the two sides of each layer of protective cover facing away from each other are provided with T-shaped slide grooves 10, and the T-shaped slider 11 moves along the T-shaped slide groove 10 to maintain the stability of movement.

[0025] Reference Figure 3-Figure 4 A guide plate 8 is provided above the T-shaped chute 10, and a moving groove 12 adapted to the guide plate 8 is provided on the inner side of each layer of the protective cover. The guide plate can prevent waste chips mixed with water from entering the T-shaped chute 10 when cleaning the protective cover, causing each layer of the protective cover to move unsmoothly. At the same time, the service life of the protective cover is improved.

[0026] Reference Figure 3 The length of the guide plate 8 is greater than the length of the T-shaped chute 10, ensuring that the guide plate 8 completely separates the T-shaped chute 10.

[0027] Reference Figure 4 The T-shaped slider 11 is fixedly connected to one end of each layer of protective cover away from the fixed plate 7. When each layer of protective cover moves, only one side is fully unfolded before the other protective cover can be extended, thereby fully utilizing the length of the protective cover.

[0028] Working principle:

[0029] When the first protective cover 1 extends to one side, the internal T-shaped slider 11 moves along the T-shaped slot 10 on the outside of the second protective cover. When the first protective cover 1 is fully unfolded, the T-shaped slider 11 will abut against one end of the T-shaped slot 10 to pull out the second protective cover 2, and so on. Each layer of the protective cover will be fully used. When the first protective cover 1 takes in the second layer, the cleaning inclined plate 9 on one side of the first protective cover 1 pushes the waste on the surface of the second protective cover to clean it and pile it together for centralized treatment. When cleaning the unfolded multi-layer protective cover, it is rinsed with water. Since the guide plate 8 is located above the T-shaped slot 10, it prevents the protective cover from being cleaned, and the waste mixed with water enters the T-shaped slot 10, causing each layer of the protective cover to move unsmoothly. At the same time, the service life of the protective cover is improved.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
