Description

Technical Field

[0001] This utility model relates to the field of wire harness protection technology, specifically a wire harness protection component for CNC machine tools. Background Technology

[0002] CNC machine tools are widely used in industrial production. The connection between the CNC machine tool and the CNC host machine relies on complex wiring harnesses. These harnesses are responsible for transmitting power and signals to ensure the normal operation of the machine tool. In order to allow operators to move around freely near the CNC machine tool and observe the working status of the machine, the wiring harnesses between the CNC machine tool and the CNC host machine are usually placed on the ground and protected by protective components to prevent damage to the wiring harnesses.

[0003] However, the length of existing wire harness protection components for CNC machine tools is relatively fixed, and the distance between the CNC machine tool and the CNC host needs to be adjusted according to the actual situation of the factory. When the distance between the CNC machine tool and the CNC host is short, the protection component will be too long, making it impossible to install. When the distance between the CNC machine tool and the CNC host is long, some wire harnesses will be exposed on the ground, making it impossible to shorten the wire harnesses to achieve effective protection, which greatly reduces the adaptability of the protection component. Utility Model Content

[0004] The purpose of this utility model is to provide a wire harness protection component for CNC machine tools, so as to solve the problem mentioned in the background art that the distance between the CNC machine tool and the CNC host is uncertain, while the length of the wire harness protection component for CNC machine tools is relatively fixed, which greatly reduces the adaptability of the protection component.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wire harness protection assembly for CNC machine tools, comprising a first protective base plate, an adjusting plate slidably connected to the surface of the first protective base plate, a second protective base plate fixedly connected to the surface of the adjusting plate, a limiting block fixedly connected to the surface of the first protective base plate, a first limiting rod fixedly connected to the surface of the limiting block, a first protective cover inserted into the surface of the first limiting rod, a second protective cover slidably connected to the inner surface of the first protective cover, a limiting guide rail fixedly connected to the surface of the second protective base plate, the second protective cover slidably connected to the surface of the limiting guide rail, a second limiting rod fixedly connected to the surface of the limiting guide rail, the second protective cover inserted into the surface of the second limiting rod, a fixing nut fixedly connected to the surface of the first protective cover, a limiting bolt threadedly connected to the surface of the fixing nut, a limiting hole formed on the surface of the second protective cover, and a shielding half-tube fixedly connected to the inner side of the second protective cover.

[0006] Preferably, the bottom of the first protective base plate and the second protective base plate are provided with an installation mechanism. The installation mechanism includes an installation plate. Two sets of installation plates are provided and are respectively located at the bottom of the first protective base plate and the second protective base plate. Multi-stage telescopic rods are fixedly connected to the surface of the installation plate. The telescopic ends of the two sets of multi-stage telescopic rods are respectively fixedly connected to the bottom of the first protective base plate and the second protective base plate. Support rods are rotatably connected to the bottom of the first protective base plate and the second protective base plate.

[0007] Preferably, a guide hole is provided on the surface of the first protective base plate, the adjusting plate slides on the guide hole of the first protective base plate, the bottom sides of the first protective cover are in an "L" shape, and the second protective cover is supported by the bottom sides of the first protective cover and slides on the inner surface of the first protective cover.

[0008] Preferably, the limiting block is L-shaped, and two sets of the limiting blocks are provided. The installation position of the first protective cover is rotated on the surface of the first protective base plate. A circular groove is opened on the surface of the first protective cover, and the first protective cover is inserted into the first limiting rod through the circular groove.

[0009] Preferably, two sets of limiting guide rails are provided, and a guide groove is formed on the surface of the limiting guide rail. The bottom of the second protective cover slides on the guide groove of the limiting guide rail. A circular hole is formed at the bottom of the second protective cover, and the second protective cover is inserted into the surface of the second limiting rod through the circular hole.

[0010] Preferably, the limiting holes are provided in multiple sets and are arranged linearly and evenly. The limiting bolt is inserted into one set of limiting holes by a fixing nut. The length of the shielding half tube is the same as the length of the second protective cover and is located on one side of the limiting hole.

[0011] Preferably, the mounting plate has mounting holes on its surface, and the height of the first protective base plate and the second protective base plate can be adjusted by multi-stage telescopic rods.

[0012] Preferably, the supporting rotating rod is L-shaped and there are four sets of supporting rotating rods.

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

[0014] 1. This protective assembly allows for the sliding adjustment plate on the guide groove of the first protective base plate to change the distance between the second and first protective base plates. A first protective cover slides on the surface of the first protective base plate, causing a first limiting rod to insert into a limiting groove at the bottom of the first protective cover. A second protective cover slides on the first protective cover and slides on a limiting guide rail, causing a second limiting rod to insert into a limiting groove at the bottom of the second protective cover. A limiting bolt is rotated on a fixing nut, causing the limiting bolt to insert into one set of limiting holes, thereby limiting the distance between the first and second protective covers. The first and second protective covers are then confined to the surfaces of the first and second protective base plates, thus allowing for adjustment of the overall length of the protective assembly. This enables flexible control of the protective length, adapting to the distance between the CNC machine tool and the CNC host, and improving the adaptability of the protective assembly.

[0015] 2. This protective assembly raises the height of the first and second protective base plates on the mounting plate via multi-stage telescopic rods, allowing the support rotating rod to rotate to a vertical position on the first and second protective base plates. At this point, the first and second protective base plates descend via the multi-stage telescopic rods, causing the bottom of the support rotating rod in its vertical position to contact the ground. The support rotating rod then supports the first and second protective base plates, thereby changing the overall height of the entire protective assembly. This prevents immersion when there is water on the ground and improves the safety of the wiring harness. Attached Figure Description

[0024] 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.

[0025] Please see Figure 1-7 One embodiment provided by this utility model:

[0026] A wire harness protection assembly for CNC machine tools includes a first protective base plate 1, an adjusting plate 11 slidably connected to the surface of the first protective base plate 1, a second protective base plate 12 fixedly connected to the surface of the adjusting plate 11, a limit block 2 fixedly connected to the surface of the first protective base plate 1, a first limit rod 21 fixedly connected to the surface of the limit block 2, a first protective cover 22 inserted into the surface of the first limit rod 21, a second protective cover 23 slidably connected to the inner surface of the first protective cover 22, a limit guide rail 24 fixedly connected to the surface of the second protective base plate 12, the second protective cover 23 slidably connected to the surface of the limit guide rail 24, a second limit rod 25 fixedly connected to the surface of the limit guide rail 24, and the second protective cover 23 inserted into the second limit rod. On the surface of the first protective cover 22, a fixing nut 26 is fixedly connected to the surface of the first protective cover 22. A limit bolt 27 is threadedly connected to the surface of the fixing nut 26. A limit hole 28 is opened on the surface of the second protective cover 23. A shielding half tube 29 is fixedly connected to the inner side of the second protective cover 23. The protective assembly protects the wire harness through the first protective base plate 1, the adjusting plate 11, the second protective base plate 12, the first protective cover 22, and the second protective cover 23. The first protective base plate 1, the adjusting plate 11, the second protective base plate 12, the first protective cover 22, and the second protective cover 23 are the main body of the protective assembly. The length of the protection can be flexibly controlled to adapt to the distance between the CNC machine tool and the CNC host, thus improving the adaptability of the protective assembly.

[0027] Furthermore, the bottom of the first protective base plate 1 and the second protective base plate 12 are provided with an installation mechanism. The installation mechanism includes an installation plate 3, which is provided in two sets and is respectively set at the bottom of the first protective base plate 1 and the second protective base plate 12. Multi-stage telescopic rods 31 are fixedly connected to the surface of the installation plate 3. The telescopic ends of the two sets of multi-stage telescopic rods 31 are respectively fixedly connected to the bottom of the first protective base plate 1 and the second protective base plate 12. The bottom of the first protective base plate 1 and the second protective base plate 12 are rotatably connected to a support rod 32. The installation plate 3 of this installation mechanism is fixed to the ground by bolts. The first protective base plate 1 and the second protective base plate 12 can be raised by the multi-stage telescopic rods 31 and supported by the support rod 32, thereby preventing soaking when there is water on the ground. Under normal circumstances, the height of the first protective base plate 1 and the second protective base plate 12 can be lowered to the ground, so as to avoid the first protective base plate 1 and the second protective base plate 12 from obstructing the view.

[0028] Furthermore, a guide hole is provided on the surface of the first protective base plate 1. The adjusting plate 11 slides on the guide hole of the first protective base plate 1. The adjusting plate 11 changes the distance between the first protective base plate 1 and the second protective base plate 12 by sliding. The bottom sides of the first protective cover 22 are in an "L" shape. The second protective cover 23 is supported by the bottom sides of the first protective cover 22 and slides on the inner surface of the first protective cover 22. The second protective cover 23 and the first protective cover 22 cover and shield the first protective base plate 1, the adjusting plate 11 and the second protective base plate 12, and pass the wire harness through them to protect the wire harness.

[0029] Furthermore, the limiting block 2 is L-shaped and there are two sets of limiting blocks 2. The installation position of the first protective cover 22 is rotated on the surface of the first protective base plate 1. A circular groove is opened on the surface of the first protective cover 22, and the first protective cover 22 is inserted into the first limiting rod 21 through the circular groove. The first limiting rod 21 restricts the first protective cover 22 on the surface of the limiting block 2, preventing the first protective cover 22 from moving directly upward on the limiting block 2.

[0030] Furthermore, two sets of limiting guide rails 24 are provided, and guide grooves are opened on the surface of the limiting guide rails 24. The bottom of the second protective cover 23 slides on the guide groove of the limiting guide rail 24. A circular hole is opened at the bottom of the second protective cover 23. The second protective cover 23 is inserted into the surface of the second limiting rod 25 through the circular hole. The second limiting rod 25 restricts the second protective cover 23 on the guide groove of the second protective cover 23, preventing the second protective cover 23 from moving upward on the limiting guide rail 24.

[0031] Furthermore, multiple sets of limiting holes 28 are provided and are arranged linearly and evenly. The limiting bolt 27 is inserted into one set of limiting holes 28 through the fixing nut 26. The limiting bolt 27 restricts the second protective cover 23 from continuing to slide on the first protective cover 22, thereby locking the length of the first protective cover 22 and the second protective cover 23. The lengths of the first protective base plate 1, the adjusting plate 11 and the second protective base plate 12 are adjusted according to the lengths of the first protective cover 22 and the second protective cover 23. After the adjustment, the first protective base plate 1, the adjusting plate 11 and the second protective base plate 12 are installed through the installation mechanism to ensure that after the lengths of the first protective cover 22 and the second protective cover 23 are adjusted, the limiting bolt 27 can pass through the limiting hole 28 and restrict the second protective cover 23 from sliding on the first protective cover 22. The length of the blocking half tube 29 is the same as the length of the second protective cover 23 and is located on one side of the limiting hole 28. The blocking half tube 29 blocks the limiting bolt 27 inside the second protective cover 23 to prevent the limiting bolt 27 from touching the wire harness.

[0032] Furthermore, mounting holes are provided on the surface of the mounting plate 3. The mounting holes of the mounting plate 3 are countersunk through holes, which, together with self-tapping screws, enable quick fixing. The mounting plate 3 is installed on the ground with screws. The mounting plate 3 can adjust the height of the first protective base plate 1 and the second protective base plate 12 through the multi-stage telescopic rod 31, thereby raising the first protective base plate 1 and the second protective base plate 12 to prevent the wire harness from being soaked in water.

[0033] Furthermore, the support rod 32 is L-shaped and there are four sets of support rods 32. The support rods 32 are arranged in pairs and staggered with each other. When the support rods 32 are in a parallel state, their bottoms are in contact with the ground, supporting the first protective base plate 1 and the second protective base plate 12. After raising the first protective base plate 1 and the second protective base plate 12, the support rods 32 can be rotated to a vertical state. At this time, the support rods 32 can also support the first protective base plate 1 and the second protective base plate 12.

[0034] Working principle: The adjusting plate 11 slides on the guide groove of the first protective base plate 1 to change the distance between the second protective base plate 12 and the first protective base plate 1. The first protective cover 22 slides on the surface of the first protective base plate 1, so that the first limiting rod 21 is inserted into the limiting groove at the bottom of the first protective cover 22. The second protective cover 23 slides on the first protective cover 22 and slides on the limiting guide rail 24, so that the second limiting rod 25 is inserted into the limiting groove at the bottom of the second protective cover 23. The limiting bolt 27 is rotated on the fixing nut 26, so that the limiting bolt 27 is inserted into one of the limiting holes 28, thereby limiting the distance between the first protective cover 22 and the second protective cover 23. The first protective cover 22 and the second protective cover 23 are then restricted on the surface of the first protective base plate 1 and the second protective base plate 12, thereby adjusting the overall length of the protective component. The length of the protection can be flexibly controlled to adapt to the distance between the CNC machine tool and the CNC host, thus improving the adaptability of the protective component.

[0035] The height of the first protective base plate 1 and the second protective base plate 12 is raised by the multi-stage telescopic rods 31 on the mounting plate 3, so that the support rotating rod 32 rotates the first protective base plate 1 and the second protective base plate 12 to a vertical state. At this time, the first protective base plate 1 and the second protective base plate 12 are lowered by the multi-stage telescopic rods 31, so that the bottom of the support rotating rod 32 in the vertical state contacts the ground. At this time, the support rotating rod 32 supports the first protective base plate 1 and the second protective base plate 12, thereby changing the overall height of the entire protective assembly, which can prevent immersion when there is water on the ground and improve the safety of the wire harness.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
