Description

Technical Field

[0001] This utility model belongs to the field of cable chain testing technology, specifically relating to a dust-free cable chain testing device. Background Technology

[0002] Cleanroom cable chains, used in cleanroom environments as cable or pipeline protection devices, leverage their flexible bendability and robust structure to ensure orderly arrangement of internal cables or pipelines, preventing tangling and wear, while also preventing the entry of dust and other contaminants. They are widely used in fields with extremely high cleanliness requirements, such as electronic chip manufacturing and precision instrument production. Testing cleanroom cable chains is crucial. Testing not only verifies whether their bending performance meets standards and assesses the wear and tear on the chain itself and its internal cables during repeated bending, but also ensures the protective performance of the cable chain in cleanroom environments, preventing dust ingress due to issues such as inadequate sealing.

[0003] In cleanroom cable chain testing scenarios, it is necessary to accurately simulate the actual working state of the cable chain and test its performance parameters such as bending radius. Previous testing equipment struggled to flexibly and precisely adjust the bending radius of the cable chain; therefore, a cleanroom cable chain testing device is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a dust-free cable chain testing device that allows for quick adjustment and detection of the cable chain bending radius in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A cleanroom cable chain testing device includes a workbench and a linear motor assembly mounted on the workbench. The workbench is provided with a detection guide groove. The device also includes:

[0007] A sliding plate, which is slidably mounted on the linear motor assembly;

[0008] A fixing mechanism is provided on the sliding plate. One end of the drag chain is fixed by the fixing mechanism, and the bending radius is changed by changing the position of the sliding plate on the linear motor assembly.

[0009] Rack 1, wherein rack 1 is mounted on the linear motor assembly;

[0010] Rack 2 is slidably mounted on the sliding plate. By adjusting the fixing mechanism, rack 2 is made to mesh with rack 1, thereby fixing the position of the sliding plate on the linear motor assembly.

[0011] As a further optimization of this utility model, the fixing mechanism includes a mounting plate, which is fixedly mounted on a sliding plate. A second screw is rotatably mounted on the mounting plate, and a second clamping plate is threaded onto the second screw. A sliding rod is mounted at one end of the second clamping plate, and the sliding rod is slidably mounted on the mounting plate.

[0012] As a further optimization of this utility model, side plates are provided on both sides of the sliding plate, a pressure plate is slidably provided on the sliding plate, a spring is provided between the pressure plate and the sliding plate, a trapezoidal block is provided on the pressure plate, and the pressure plate abuts against the sliding rod.

[0013] As a further optimization of this utility model, a connecting post is provided on the rack two, the connecting post is slidably disposed through the side plate, an inclined block is provided on the connecting post, the inclined block cooperates with the trapezoidal block, a spring two is provided between the rack two and the side plate, and the rack two can engage with the rack one.

[0014] As a further optimization of this utility model, the linear motor assembly includes a stator, the stator is mounted on a workbench, a track is mounted on the workbench, a mover is slidably mounted on the track, and a sliding plate is slidably mounted on the mover.

[0015] As a further optimization of this utility model, a horizontal plate is provided on the detection guide groove, a clamping plate is slidably provided on the detection guide groove, and a screw is rotatably provided on the clamping plate, the screw being threadedly connected to the horizontal plate.

[0016] The beneficial effects of this utility model are as follows: Unlike the prior art, in actual use, the bending radius of the cable chain can be easily changed by changing the position of the sliding plate on the mover of the linear motor unit, accurately simulating the actual working conditions of the cable chain and improving the accuracy of the test. On the other hand, when fixing the cable chain, the sliding rod of the fixing mechanism pushes the pressure plate to compress the spring one downward, the trapezoidal block on the pressure plate pushes the inclined block, and drives the connecting column to make the rack two overcome the resistance of the spring two and mesh with the rack one on the linear motor unit, thereby quickly fixing the position of the sliding plate during the fixing of the cable chain.

It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0023] Example 1

[0024] like Figure 1 - Figure 5 As shown, a cleanroom cable chain testing device includes a workbench 1 and a linear motor assembly 2 mounted on the workbench 1. The workbench 1 is provided with a detection guide groove 3. The device also includes:

[0025] Sliding plate 6 is slidably mounted on linear motor assembly 2;

[0026] The fixing mechanism 4 is set on the sliding plate 6. One end of the drag chain is fixed by the fixing mechanism 4. The bending radius is changed by changing the position of the sliding plate 6 on the linear motor group 2.

[0027] Rack 5, rack 5 is mounted on linear motor assembly 2;

[0028] Rack 2 8 is slidably mounted on slide plate 6. By adjusting fixing mechanism 4, rack 2 8 is made to mesh with rack 1 5, thereby fixing the position of slide plate 6 on linear motor assembly 2.

[0029] The fixing mechanism 4 includes a mounting plate 41, which is fixedly mounted on the sliding plate 6. A screw 44 is rotatably mounted on the mounting plate 41, and a clamping plate 42 is threaded onto the screw 44. A sliding rod 43 is mounted at one end of the clamping plate 42, and the sliding rod 43 is slidably mounted on the mounting plate 41. When the screw 44 is rotated, the clamping plate 42 drives the sliding rod 43 to slide on the mounting plate 41 through threaded transmission, thereby firmly clamping the cable chain.

[0030] Side plates 61 are provided on both sides of the sliding plate 6. A pressure plate 71 is slidably provided on the sliding plate 6. A spring 72 is provided between the pressure plate 71 and the sliding plate 6, so that the pressure plate 71 has a restoring force. A trapezoidal block 7 is provided on the pressure plate 71. The pressure plate 71 abuts against the slide rod 43. In this way, when the position of the slide rod 43 changes, the pressure plate 71 moves with the slide rod 43 with the cooperation of the spring 72.

[0031] A connecting post 82 is provided on rack 2 8, which is slidably mounted on side plate 61. An inclined block 83 is provided on the connecting post 82, which cooperates with trapezoidal block 7. By changing the position of trapezoidal block 7, rack 2 8 can move to both sides. A spring 2 81 is provided between rack 2 8 and side plate 61, so that rack 2 8 has a reset force. Rack 2 8 can mesh with rack 1 5, so that the position of rack 2 8 can be fixed.

[0032] The linear motor assembly 2 includes a stator 21, which is mounted on a workbench 1. A track 22 is mounted on the workbench 1, and a mover 23 is slidably mounted on the track 22. A sliding plate 6 is slidably mounted on the mover 23. As a driving component, the linear motor assembly 2 has a fast response speed and high operating accuracy, and can provide stable and accurate power for the testing process.

[0033] A horizontal plate 31 is provided on the detection guide groove 3, and a clamping plate 32 is slidably provided on the detection guide groove 3. A screw 33 is rotatably provided on the clamping plate 32. The screw 33 is threadedly connected to the horizontal plate 31. By rotating the screw 33, the clamping plate 32 can slide along the detection guide groove 3, thereby quickly fixing one end of the cable chain. This design is convenient to operate, accurate in positioning, and greatly improves the preparation efficiency before testing.

[0034] It should be noted that the cleanroom cable chain testing equipment is installed on the workbench 1, with the linear motor assembly 2 serving as the driving component. This assembly consists of a stator 21, a track 22, and a mover 23. The stator 21 is fixed to the workbench 1, while the mover 23 can slide along the track 22. The sliding plate 6 is mounted on the mover 23 and can move with it. During testing, one end of the cable chain is fixed to the detection guide groove 3 by a clamping plate 32. By rotating the screw 33, the position of the clamping plate 32 on the detection guide groove 3 can be adjusted to fix one end of the cable chain. The other end is fixed to the sliding plate 6 by a fixing mechanism 4. The mounting plate 41 of the fixing mechanism 4 is fixed to the sliding plate 6. Rotating the screw 44 causes the clamping plate 42 to slide on the mounting plate 41 due to the threaded transmission of the screw 44, thereby clamping the cable chain. During this process, the slide bar 43 pushes the pressure plate 71 to compress the spring 72 and move downwards. The trapezoidal block 7 on the pressure plate 71 pushes the inclined block 83, causing the connecting column 82 to drive the rack 8 to overcome the resistance of the spring 81 and mesh with the rack 5 on the linear motor assembly 2, thereby fixing the position of the sliding plate 6. In this way, the position of the sliding plate 6 is fixed during the fixing process of the cable chain. Depending on the height of the sliding plate 6 at the mover 23, the bending radius of the cable chain can be changed during the detection.

[0035] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
