Description

Technical Field

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

[0002] Cable chains, also known as cable protection cable chains, are devices used to secure cables, wires, air hoses, and hydraulic hoses to facilitate their rotation and movement. Cable chains are divided into steel cable chains and plastic cable chains. Steel cable chains are made of steel and aluminum and can be customized. Plastic cable chains are also called engineering plastic cable chains or tank chains. Depending on the usage environment and requirements, cable chains are classified into bridge cable chains, fully enclosed cable chains, and semi-enclosed cable chains. Rectangular metal hoses, protective sleeves, corrugated pipes, and metal flexible hoses can also be included in cable chain protection and mobile power supply products. Cable chains are used in reciprocating motion applications, providing traction and protection for internal cables, oil pipes, air pipes, water pipes, etc. Cable chains are widely used in CNC machine tools, electronic equipment, glass machinery, injection molding machine robots, handling machinery, plastic machinery, lifting equipment, woodworking machinery, the automotive industry, industrial vehicles, metal processing machinery, machine tools, casting machinery, port equipment, and other industries.

[0003] According to a public notice regarding a machine tool cable carrier with cable protection (publication number: CN217668200U), the aforementioned application uses a support roller that rotates around the axis of the shaft and uses a circular anti-slip sleeve to support the upper and lower sections of the cable carrier body, thereby 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, the distance between the upper and lower support rollers on the side wall of the fixed plate cannot be adjusted, making it impossible to match different sizes of cable chain models. This results in the cable chain body not being able to be fully embedded between the support rollers, affecting the support effect. Utility Model Content

[0005] The purpose of this invention is to provide a machine tool cable chain with good stability 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 good stability, comprising a cable chain body and a back plate. A groove is formed on the surface of the back plate, and a support assembly for supporting the cable chain body is provided inside the groove. The support assembly includes a movable seat, which is slidably connected inside the groove. Two sets of movable seats are symmetrically arranged, and the two sets of movable seats are threadedly connected by a bidirectional threaded rod. A first bearing plate is fixedly connected to the side wall of the movable seat. Multiple sets of neatly distributed support rollers are rotatably connected to the side wall of the first bearing plate. The ends of the support rollers are rotatably connected to a second bearing plate, and the support rollers are in contact with the inner ring wall of the cable chain body.

[0007] Preferably, the inner wall of the cable chain body is provided with a clamping assembly, the clamping assembly includes a through groove, the through groove is provided on the surface and bottom surface of the cable chain body, two sets of symmetrically arranged sliders are slidably connected inside the through groove, a spring is provided between the slider and the through groove, and a clamping plate is fixedly connected to the bottom end of the slider.

[0008] Preferably, one end of the bidirectional threaded rod is rotatably connected to the inner wall of the groove, and the other end of the bidirectional threaded rod is fixedly connected to a rotating wheel.

[0009] Preferably, the two sets of sliders are slidably connected by a sliding rod, the end of which is fixedly connected to the inner wall of the through groove.

[0010] Preferably, the top of the inner wall of the cable chain body is fixedly connected to the ground with an arc-shaped pad, and the bottom surface of the clamping plate has a notch that matches the arc-shaped pad.

[0011] Preferably, the side wall of the clamp is fixedly connected with a rubber pad.

[0012] Preferably, the spring is sleeved on the outer wall of the slide rod.

[0013] Preferably, the bidirectional threaded rod is rotatably connected to the top of the back plate.

[0014] Compared with the prior art, this utility model provides a machine tool cable chain with good stability, which has the following beneficial effects:

[0015] 1. This machine tool cable chain with good stability can flexibly adjust the spacing of the support rollers through the combination of bidirectional threaded rod and moving seat, and can be adapted to different models of cable chain bodies, solving the problem of poor adaptability of the cable chain support structure in the existing technology; at the same time, the support rollers convert the sliding friction of the inner ring of the cable chain into rolling friction, and the double plate fixing structure prevents deviation, reducing cable chain wear while ensuring the stability of the trajectory when the cable chain reciprocates.

[0016] 2. This machine tool cable chain with good stability uses a spring-driven clamping plate assembly to achieve flexible clamping of cables. The rubber pad can avoid damage to the cable insulation layer by rigid clamping, and the elastic adjustment capability of the spring can adapt to cables of different diameters, solving the problems of easy damage to cables and narrow adaptation range in existing technologies. At the same time, the arc-shaped pad matches the notch of the clamping plate, further reducing cable friction without affecting the sliding of the clamping plate, thus improving the safety of cable use.

[0021] like Figures 1-3 As shown, this utility model provides a technical solution: a machine tool cable chain with good stability, including a cable chain body 1 and a back plate 2. A groove 21 is formed on the surface of the back plate 2. A support component 3 for supporting the cable chain body 1 is arranged inside the groove 21. The support component 3 includes a movable seat 31, which is slidably connected inside the groove 21. Two sets of movable seats 31 are symmetrically arranged, and the two sets of movable seats 31 are threadedly connected to each other by a bidirectional threaded rod 32. The bidirectional threaded rod 32 passes through and is rotatably connected to the top of the back plate 2. One end of the bidirectional threaded rod 32 is rotatably connected to the inner wall of the groove 21, and the other end of the bidirectional threaded rod 32 is fixedly connected to a rotating wheel 33. By cooperating with the rotating wheel 33, the two sets of movable seats 31 can be driven to slide in opposite or the same direction along the groove 21 after rotating the rotating wheel 33, thereby adjusting the distance between the two sets of upper and lower support rollers 35 to adapt to different models of cable chain bodies 1.

[0022] A first support plate 34 is fixedly connected to the side wall of the movable seat 31. Multiple sets of evenly distributed support rollers 35 are rotatably connected to the side wall of the first support plate 34. These support rollers 35 are in contact with the inner wall of the cable chain body 1. When the cable chain reciprocates, the support rollers 35 rotate synchronously with the cable chain body 1, converting sliding friction into rolling friction, reducing wear on the inner ring of the cable chain body 1, and extending its service life. The ends of the support rollers 35 are rotatably connected to a second support plate 36, which is also in contact with the inner wall of the cable chain body 1. The two ends of the support rollers 35 are connected to the first support plate 34 and the second support plate 36 respectively, forming a double-plate fixed structure to prevent the support rollers 35 from shifting and ensure the stability of the cable chain body 1's running trajectory.

[0023] The inner wall of the cable chain body 1 is provided with a clamping assembly 4, which includes a through groove 41. Through grooves 41 are formed on both the surface and bottom of the cable chain body 1. Two sets of symmetrically arranged sliders 42 are slidably connected inside the through grooves 41. The two sets of sliders 42 are slidably connected by a sliding rod 43. The end of the sliding rod 43 is fixedly connected to the inner wall of the through groove 41. A spring 44 is provided between the slider 42 and the through groove 41, and the spring 44 is sleeved on the outer wall of the sliding rod 43. A clamping plate 45 is fixedly connected to the bottom end of the slider 42. When a cable is placed, the clamping plate 45 is squeezed by the cable, causing the slider 42 to slide along the sliding rod 43, compressing the spring 44. When the spring 44 returns to its original position, it can drive the clamping plate 45 to automatically conform to the surface of the cable, thus adapting to cables of different diameters.

[0024] Rubber pads 451 are fixedly connected to the side walls of the clamping plate 45. Arc-shaped pads 46 are fixedly connected to the top of the inner wall of the cable chain body 1 and to the ground. A notch 47 matching the arc-shaped pad 46 is provided on the bottom surface of the clamping plate 45. The rubber pads 451 on the side walls of the clamping plate 45 prevent rigid clamping from damaging the cable insulation layer. The arc-shaped pad 46 fits snugly against the notch 47 of the clamping plate 45, preventing it from affecting the sliding of the clamping plate 45. Simultaneously, the arc-shaped pad 46 reduces friction with the cable, improving the cable's service life.

[0025] In this utility model, during use, first adjust the support assembly 3 according to the model of the cable chain body 1, rotate the rotating wheel 33 to drive the bidirectional threaded rod 32 to rotate, so that the two sets of moving seats 31 slide along the groove 21 in the same or opposite directions until the support rollers 35 on the two sets of moving seats 31 are tightly fitted with the inner ring wall of the cable chain body 1. The double plate fixing structure of the first support plate 34 and the second support plate 36 ensures that the support rollers 35 do not shift; then put the cable into the inside of the cable chain body 1, the cable squeezes the clamping plate 45, drives the slider 42 to slide along the slide rod 43 and compress the spring. Spring 44, after the cable is placed in place, spring 44 resets and pushes slider 42 to move, so that clamp 45 fits against the surface of cable. Rubber pad 451 avoids damage to cable insulation layer. Arc-shaped pad 46 matches the notch 47 of clamp 45, does not affect the sliding of clamp 45 and reduces cable friction. When the drag chain body 1 reciprocates, the support roller 35 rotates synchronously with the drag chain, converting the sliding friction of the inner ring of the drag chain into rolling friction, reducing wear. At the same time, clamping component 4 continuously flexibly fixes the cable, ensuring the stability of the drag chain running trajectory and the cable is not easy to shake.

[0026] 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.
