Description

Technical Field

[0001] This utility model relates to the field of cable drag chain technology, specifically a machine tool drag chain with cable protection. Background Technology

[0002] Cable drag chains, also known as cable protection drag chains, are devices used to secure cables, wires, pneumatic hoses, and hydraulic hoses to facilitate their rotation and movement. Cable drag chains are divided into steel drag chains and plastic drag chains. Steel drag chains are made of steel and aluminum and can be customized. Plastic drag chains are also called engineering plastic drag chains or tank chains. Depending on the usage environment and requirements, cable drag chains are classified into three types: bridge drag chains, fully enclosed drag chains, and semi-enclosed drag chains. Rectangular metal flexible hoses, protective sleeves, corrugated pipes, and metal flexible hoses can also be included in cable drag chain protection and mobile power supply products.

[0003] According to a public notice (No.: CN217668200U) of a machine tool cable carrier with cable protection, the cable inside the cable carrier body passes between two semi-circular protective sleeves. Two telescopic rods and telescopic springs connect the two semi-circular protective sleeves through two connecting plates. The two semi-circular protective sleeves and two semi-circular rubber pads protect the cable inside the cable carrier body, preventing the cable from getting tangled due to the movement of the cable carrier body. At the same time, it prevents the cable from being affected by friction between the cable and the inner wall of the cable carrier body, thus reducing the cable's service life. When the cable carrier body is in operation, the support roller rotates around the axis of the shaft and supports the upper and lower sections of the cable carrier body through a circular anti-slip sleeve, improving the stability of the cable carrier body during operation and preventing the upper and lower sections of the cable carrier body from deforming due to gravity.

[0004] However, in actual use, the length of the cable chain is adjusted by disassembling or installing the cable chain body. But in practice, the actual required length often cannot perfectly match the needs of the equipment, and the cable chain cannot be offset at small angles. In view of this, we propose a machine tool cable chain with cable protection. Utility Model Content

[0005] The purpose of this invention is to provide a machine tool cable chain with cable protection to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A machine tool cable chain with cable protection includes a cable chain body, an installation groove is provided at the end of the cable chain body, a clamping component is provided in the installation groove, and an adjustment mechanism capable of flexibly adjusting the size of the cable chain is provided on the side wall of the cable chain body, the adjustment mechanism including:

[0007] A connector, the side wall of which abuts against the side wall of the drag chain body, the inside of which is provided with a sliding groove, the inner wall of which is slidably connected with a limit block, the end of which is away from the sliding groove is fixedly connected with a connecting rod, and the inside of which is provided with a limit groove.

[0008] A compression spring is provided, with one end of the compression spring disposed on the bottom surface of the limiting groove, and the other end of the compression spring is fixedly connected to a fixing block.

[0010] Preferably, the end of the fixing block away from the compression spring is fixedly connected to a left fixing plate and a right fixing plate, and the outer surfaces of the left fixing plate and the right fixing plate abut against each other.

[0011] Preferably, the number of connecting rods is set in multiple sets, with each pair of connecting rods arranged in a mirror image symmetrically at the end of the limiting block away from the slide groove.

[0012] Preferably, the left and right fixed plates are provided with a connecting mechanism that can assist the connector in angular deflection. The connecting mechanism includes a connecting groove, which is opened inside the left fixed plate and passes through the right fixed plate. A connecting shaft is fixedly connected to the end of the connecting groove. One end of a spiral spring is fixedly connected to the outer wall of the connecting shaft. The other end of the spiral spring is fixedly connected to the inner wall of the right fixed plate. A hinge seat is fixedly connected to the end of the connecting rod away from the limiting block.

[0016] Compared with the prior art, this utility model provides a machine tool cable chain with cable protection, which has the following advantages:

[0017] 1. This machine tool cable carrier with cable protection, through the coordinated design of an adjustment mechanism, connector, slide, limit block, connecting rod, compression spring, and fixing block, achieves flexible adjustment of the cable carrier size. The dumbbell-shaped slide inside the connector cooperates with the limit block to allow the connecting rod to slide within the slide. The elasticity of the compression spring ensures that the limit block is stably fixed at the large size of the slide, thereby ensuring a smooth and reliable adjustment process.

[0018] 2. This machine tool cable carrier with cable protection, through a clever combination of a connecting mechanism, connecting groove, connecting shaft, spiral spring, and hinge seat, achieves flexible angular deflection of the connecting parts. The connecting shaft and spiral spring are embedded between the left and right fixed plates, and the spiral spring provides continuous restoring force, allowing the connecting parts to automatically return to their original position after deflection, ensuring a smooth transition of the cable carrier during bending or torsional movements. The hinge seat connects its left and right parts through a hinge shaft, further increasing the mechanism's degree of freedom and adaptability. Attached Figure Description

[0025] like Figures 1-5As shown, this utility model provides a technical solution: a machine tool cable carrier with cable protection, including a cable carrier body 1, an installation groove 11 is provided at the end of the cable carrier body 1, a clamping component 12 is provided in the installation groove 11, and an adjustment mechanism 2 that can flexibly adjust the size of the cable carrier is provided on the side wall of the cable carrier body 1. The adjustment mechanism 2 includes: a connector 21, a slide 22, a limiting block 23, a connecting rod 24, a limiting groove 25, a compression spring 26, a fixing block 27, a left fixing plate 28, and a right fixing plate 29.

[0026] In one embodiment of this utility model, the sidewall of the connector 21 abuts against the sidewall of the drag chain body 1. A groove 22 is provided inside the connector 21, and a limiting block 23 is slidably connected to the inner wall of the groove 22. A connecting rod 24 is fixedly connected to the end of the limiting block 23 away from the groove 22. A limiting groove 25 is provided inside the connector 21. A compression spring 26 is provided, with one end of the compression spring 26 located on the bottom surface of the limiting groove 25, and a fixing block 27 fixedly connected to the other end of the compression spring 26. Multiple sets of fixing blocks 27 are provided, with each pair of sets of fixing blocks 27 distributed symmetrically in a mirror image at the end of the compression spring 26 away from the limiting groove 25. The connector 21 is symmetrically configured, and the grooves 22 and limiting grooves 25 are provided in the two symmetrically configured connectors 21. The shape of the groove 22 is dumbbell-shaped, and the size of the limiting block 23 matches the larger size of the dumbbell-shaped groove 22. A left fixing block 24 is fixedly connected to the end of the fixing block 27 away from the compression spring 26. The left and right fixed plates 28 and 29 are connected, with the outer surfaces of the left and right fixed plates 28 and 29 abutting each other. Multiple sets of connecting rods 24 are provided, with each pair of connecting rods 24 arranged in a mirror image symmetrically at the end of the limiting block 23 away from the slide groove 22. By providing the slide groove 22 and the limiting groove 25, the two sets of connecting parts 21 can have a certain size adjustment effect under the combined action of the limiting block 23, the connecting rods 24, the compression spring 26, the fixed block 27, the left fixed plate 28, and the right fixed plate 29. When a fine adjustment of the size is required, one set of connecting parts 21 in the two sets of mirror-symmetrically arranged connecting parts 21 will be pulled, so that the limiting block 23 and the connecting rods 24 can slide in the slide groove 22. The dumbbell-shaped slide groove 22 can cooperate with the connecting rods 24 and the limiting block 23 to restrict the limiting block 23. The left fixed plate 28 and the right fixed plate 29, together with the compression spring 26, can enable the connecting parts 21 to have a reset effect.

[0027] Additionally, the left fixed plate 28 and the right fixed plate 29 are equipped with connecting mechanisms 3 that assist the connector 21 in angular deflection. The connecting mechanism 3 includes a connecting groove 31, which is located inside the left fixed plate 28 and extends through the right fixed plate 29. A connecting shaft 32 is fixedly connected to the end of the connecting groove 31. One end of a spiral spring 33 is fixedly connected to the outer wall of the connecting shaft 32, and the other end of the spiral spring 33 is fixedly connected to the inner wall of the right fixed plate 29. A hinge seat 34 is fixedly connected to the end of the connecting rod 24 away from the limiting block 23. The hinge seat 34 is configured with a left part and a right part, and the left part and the right part of the hinge seat 34 are connected by the hinge shaft 35. When the entire cable chain needs to be deflected at a certain angle, the connecting groove 31 and the connecting shaft 32, together with the spiral spring 33, can enable the two sets of mirror-symmetrically arranged connecting parts 21 to have a certain angle deflection effect. The spiral spring 33 can also cause the connecting parts 21 to reset. When the connecting parts 21 deflect at an angle, the left part and the right part of the hinge seat 34 can synchronously adapt to the angle deflection under the action of the hinge shaft 35.

[0028] In an embodiment of this utility model, a circular fixing groove is provided on the outer wall of the connector 21, and a fixing pin 4 abuts against the inner wall of the fixing groove. The connector 21 is connected to the side wall of the cable chain body 1 through the fixing pin 4. The number of cable chain body 1 and connector 21 is set in several groups, and the several groups of cable chain body 1 and connector 21 are arranged to cooperate with each other. The length of the entire cable chain can be flexibly adjusted through the fixing pin 4, thereby facilitating the use of the machine tool.

[0029] In this utility model, when the cable chain size needs to be adjusted, the limiting block 23 inside the connector 21 can slide in the dumbbell-shaped groove 22, and drive the left fixed plate 28 and the right fixed plate 29 to move through the connecting rod 24. The compression spring 26 provides elastic tension to maintain structural stability. At the same time, the hinge seat 34 in the connecting mechanism 3 is deflected through the hinge shaft 35. The spiral spring 33 inside it is wound or released on the connecting shaft 32, which can flexibly adapt to different working strokes. It can not only effectively protect the internal cables, but also flexibly adjust the size, length and deflection angle in actual work.

[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
