Description

Technical Field

[0001] This utility model relates to the field of detection device technology, and in particular to a device for detecting the elongation of insulating sheaths. Background Technology

[0002] Insulating sheaths are protective layers used to wrap wires, cables, or other electrical equipment. Because cables may be subjected to bending and stretching during use (such as drag chain cables and mobile equipment cables), the sheath needs to have sufficient elongation to prevent breakage. Therefore, the elongation of the insulating sheath is usually tested during the manufacturing process to determine its quality.

[0003] Existing testing devices typically include a worktable and a displacement plate. The displacement plate is provided with mating holes for the insulating sheath to pass through, and is specifically designed with clamping structures for fixing the insulating sheath (located in the mating holes).

[0004] However, the diameter of the mating hole is usually fixed, which means that when testing insulation sheaths of different diameter specifications, it is necessary to change the equipment for testing, resulting in high workshop equipment costs (requiring multiple testing devices) and limited flexibility in the use of testing devices. Utility Model Content

[0005] The main purpose of this utility model is to provide an insulation sheath elongation testing device, which aims to solve the problem in related technologies where the diameter of the mating hole on the displacement plate for the insulation sheath to pass through is fixed, resulting in limited flexibility in the use of the testing device.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: An insulating sheath elongation testing device includes a worktable, a displacement plate, and a drive mechanism for controlling the movement of the displacement plate. The displacement plate is provided with a clamping structure and a mating component. The mating component has a mating hole for the insulating sheath to pass through it and a mating opening for the clamping structure to contact the insulating sheath located in the mating hole. The mating component is detachably connected to the displacement plate. The projection surface of the mating hole in its axial direction is rectangular.

[0007] Furthermore, the clamping structure includes a lifting screw and a clamping plate, wherein the lifting screw is threadedly connected to a displacement pull plate, and the clamping plate and the lifting screw are linked together.

[0008] Furthermore, the lifting screw includes a rotating linkage part, and the clamping plate is provided with a linkage groove for cooperating with the rotating linkage part. The longitudinal section of the rotating linkage part and the linkage groove are both inverted "T" shaped structures, and the clamping plate abuts against the mating part.

[0009] Furthermore, the end of the clamping plate that is close to the mating part and the end of the mating hole that is away from the clamping plate are both provided with anti-slip textures.

[0010] Furthermore, the projected surface of the mating component in the axial direction of the mating hole is a rectangular structure.

[0011] Furthermore, the mating component includes a fixing plate with a plurality of fixing holes, and the displacement pull plate with a plurality of connecting holes. Each connecting hole and each fixing hole are coaxially arranged and are connected by a threaded component. The number of fixing holes on the end of the fixing plate close to the clamping structure is less or more than the number of fixing holes on the end of the fixing plate away from the clamping structure.

[0012] The working principle and beneficial effects of this utility model are as follows: This utility model's technical solution involves setting the mating hole on the traditional displacement pull plate onto the mating component, and detachably connecting the mating component to the displacement pull plate. This allows the insulating sleeve to pass through the displacement pull plate normally (along the mating hole), and the insulating sleeve is fixed by the clamping structure on the displacement pull plate. Thus, after the displacement pull plate is displaced, the insulating sleeve can be stretched. Thus, when the size of the insulating sleeve to be tested changes, the present invention can be adapted to various specifications of insulating sleeves by replacing the mating parts, effectively improving the flexibility of the present invention in use.

[0016] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0018] like Figure 1 As shown in the figure, this embodiment proposes an insulation sheath elongation detection device, which mainly includes a worktable 1, a displacement plate 2, and a drive mechanism 3 for controlling the movement of the displacement plate 2. The displacement plate 2 and the drive mechanism 3 are both located on the worktable 1. The drive mechanism 3 is preferably a lead screw drive mechanism to achieve high-precision movement of the displacement plate 2. Specifically, the drive mechanism 3 mainly includes a drive lead screw and a drive motor. The displacement plate 2 is connected to the drive lead screw, and the drive lead screw is linked to the output shaft of the drive motor. The drive motor is fixedly mounted on the worktable 1 to ensure that the drive mechanism 3 stably provides driving force to the displacement plate 2, causing the displacement plate 2 to move.

[0019] like Figures 2-4 As shown, the displacement plate 2 is provided with a clamping structure 4 and a mating part 5. The mating part 5 is provided with a mating hole 51 for the insulating sheath to pass through itself and a mating opening 52 for the clamping structure 4 to contact the insulating sheath located in the mating hole 51. That is, the insulating sheath can be fixed in the mating hole 51 by the mutual cooperation between the clamping structure 4 and the wall of the mating hole 51.

[0020] Meanwhile, the mating part 5 is detachably connected to the displacement pull plate 2. That is, when the size of the insulation sheath being tested changes, the specification of the mating hole 51 can be changed by replacing the mating part 5 (the size of the mating hole 51 on each mating part 5 is different), so that the mating hole 51 can always be matched with the insulation sheath being tested. In this way, there is no need to replace the testing equipment due to the change in the size of the insulation sheath, which reduces the equipment requirements of the testing workshop and effectively improves the flexibility of use of this embodiment.

[0021] Preferably, in this embodiment, the drive screw is a double-ended screw, with displacement plates 2 connected to both ends of the double-ended screw. Thus, each displacement plate 2 can move synchronously in opposite directions, completing the stretching of the insulating sleeve located on each displacement plate 2. Preferably, the insulation sleeve is considered undamaged when the distance between each displacement plate 2 reaches a specified value, which can be used to test whether the elongation rate of the insulation sleeve is qualified.

[0022] The clamping structure 4 includes a lifting screw 41 and a clamping plate 42. The lifting screw 41 is threadedly connected to the displacement pull plate 2. The clamping plate 42 and the lifting screw 41 are linked together. That is, by rotating the lifting screw 41, the lifting screw 41 moves on the displacement pull plate 2, and drives the clamping plate 42 to move accordingly, thereby clamping the insulating sheath.

[0023] Specifically, the lifting screw 41 includes a rotating linkage part 411, and the clamping plate 42 is provided with a linkage groove 421 for cooperating with the rotating linkage part 411. The longitudinal section of both the rotating linkage part 411 and the linkage groove 421 is an inverted "T" shaped structure. The special structure of the "T" shaped groove can effectively constrain the positional relationship between the lifting screw 41 and the clamping plate 42, and prevent the clamping plate 42 from detaching from the lifting screw 41 during the linkage process with the lifting screw 41. The displacement pull plate 2 is provided with a relief groove. When the clamping plate 42 is located in the relief groove, the clamping plate 42 abuts against the groove wall of the relief groove. When the clamping plate 42 is located in the mating part 5, the clamping plate 42 abuts against the mating part 5 (in sequence abutting against the mating opening 52 and the mating hole 51), so that the clamping plate 42 will only rise and fall with the rotation and lifting movement of the lifting screw 41.

[0024] The projection surface of the mating hole 51 in its axial direction is rectangular. When the mating hole 51 is a conventional circular design, the clamping plate 42 is prone to interference with its arc-shaped hole wall structure, resulting in a limited movement distance of the clamping plate 42 and easily reducing the scope of use of this embodiment. The rectangular hole structure can avoid this phenomenon from the root and provide a guarantee for the scope of use of this embodiment.

[0025] When the length of the mating hole 51 is less than the length of the mating opening 52, the mating opening 52 can be extended to form mating grooves on both sides of the mating hole 51, so that the clamping plate 42 can maintain normal movement.

[0026] The clamping plate 42 is provided with anti-slip texture 6 at the end close to the mating part 5 and the mating hole 51 is provided away from the clamping plate 42. The presence of anti-slip texture 6 enhances the friction between the insulating sleeve and the clamping plate 42 or the mating hole 51, thereby preventing slippage during the clamping of the insulating sleeve and ensuring the clamping stability of the insulating sleeve.

[0027] The projection surface of the mating part 5 in the axial direction of the mating hole 51 is rectangular, which prevents it from rotating when the displacement pull plate 2 is installed, and facilitates the fixed installation of the mating part 5.

[0028] The mating component 5 includes a fixing plate 53. A plurality of fixing parts 7 are provided between the fixing plate 53 and the displacement pull plate 2 for fixing the fixing plate 53 to the displacement pull plate 2. In this embodiment, each fixing part 7 is preferably a commonly available threaded fastener such as a bolt, so that a replacement can be quickly found if it is accidentally lost. That is, the displacement pull plate 2 and the mating component 5 are fixedly connected to each other by means of threaded connection of the fixing parts 7, which not only ensures the connection stability between the two, but also facilitates the disassembly and replacement of the mating component 5 in the later stage.

[0029] Correspondingly, the fixing plate 53 is provided with several connecting holes for the fixing member 7 to pass through itself, and the displacement pull plate 2 is provided with several fixing holes that are coaxially arranged with each connecting hole. Each fixing member 7 is threadedly connected to each fixing hole.

[0030] The number of fixing pieces 7 on the end of the fixing plate 53 close to the clamping structure 4 is less or more than the number of fixing pieces 7 on the end of the fixing plate 53 away from the clamping structure 4. In this way, when installing the mating part 5, the correct installation position can be quickly found by calibrating each fixing hole and each connecting hole, effectively avoiding the discovery that the clamping plate 42 cannot enter the mating part 5 after the mating part 5 is installed, and further improving the installation efficiency of the mating part 5.

In the description of this application, it should be understood that if terms such as "upper," "lower," "left," and "right" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, they are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.
