Description

Technical Field

[0001] This utility model belongs to the field of cable testing, and specifically relates to a device for testing the tensile strength of cable sheaths. Background Technology

[0002] Currently, cable sheaths are an important component protecting the internal structure of cables, and their tensile strength is one of the key indicators for measuring cable quality. During the cable production process, it is necessary to test the tensile strength of the cable sheath to ensure that it meets the usage requirements.

[0003] However, cable sheaths generally have strong tensile properties in order to achieve better performance during use. Traditional tensile testing devices have a short travel distance, which can easily lead to insufficient travel when testing sheaths with good tensile properties, resulting in limitations.

[0004] Therefore, considering the shortcomings of the above-mentioned solutions in actual production and implementation, modifications and improvements have been made. Furthermore, in the spirit of striving for excellence, and with the assistance of professional knowledge and experience, and after much ingenuity and experimentation, this utility model was created. It provides a cable sheath tensile performance testing device to address the problem that existing cable sheaths, in order to achieve better performance, generally have strong tensile properties. Traditional tensile testing devices have a short travel distance, which easily leads to insufficient travel when testing sheaths with good tensile properties, resulting in limitations in effective testing. Utility Model Content

[0005] This utility model proposes a cable sheath tensile performance testing device, which solves the problem that in the prior art, cable sheaths generally have strong tensile properties when used to achieve better performance. Traditional tensile testing devices have a short stroke, which easily leads to insufficient stroke when testing sheaths with good tensile properties, resulting in ineffective testing of the sheath.

[0006] The technical solution of this utility model is implemented as follows: a cable sheath tensile performance testing device includes: a support base, a guide support fixedly connected to the center of the top surface of the support base, a slot opened inside the guide support, and a tensile sensor fixedly connected inside the slot; A guide rod assembly is fixedly connected to the top surface of the tension sensor. The guide rod assembly has a cylindrical structure, and a guide rail assembly is fixedly connected to the top surface of the guide rod assembly. The guide rail assembly is horizontally arranged, and a horizontal groove is formed inside the guide rail assembly. A clamping push rod is fixedly connected inside the horizontal groove. There are two clamping push rods, and clamping assemblies are fixedly connected to the inner side of each clamping push rod. In a preferred embodiment, sliders are fixedly connected to both the front and rear sides of the clamping assembly, the clamping assembly is slidably connected within the guide rail assembly, and a guide rod assembly is fixedly connected to the top surface of the support base.

[0007] In a preferred embodiment, the guide rod assembly is a cylindrical structure, and there are four guide rod assemblies. The four guide rod assemblies are fixedly connected to the four corners of the top surface of the support base, and a top plate assembly is also fixedly connected to the top surface of the four guide rod assemblies.

[0008] In a preferred embodiment, the support base and the guide rod assembly together form a support structure for the top plate assembly, and a vertical plate mechanism is fixedly connected to the bottom surface of the top plate assembly, with the vertical plate mechanism being perpendicular to the bottom surface of the top plate assembly.

[0009] In a preferred embodiment, the upright plate mechanism is provided in two locations, and the two upright plate mechanisms are fixedly connected to the front and rear sides of the bottom end face of the top plate assembly in opposite directions. A support plate assembly is also fixedly connected to the front end face of the upright plate mechanism located on the front side.

[0010] In a preferred embodiment, a servo motor is fixedly connected to the top surface of the support plate assembly, and an output shaft is provided at the bottom end of the servo motor, on which a bevel gear A is mounted.

[0011] In a preferred embodiment, a rotating shaft assembly is rotatably connected to the inner side of the upright plate mechanism. A bevel gear B is coaxially mounted at the front end of the rotating shaft assembly. The bevel gear B meshes with the bevel gear A for transmission. A take-up roller is also fixedly connected to the outer side of the rotating shaft assembly. A test piece with a protective sleeve structure is wound around the outer side of the take-up roller. A fixing bolt for limiting the test piece is screwed onto the outer side of the take-up roller.

[0012] After using the above technical solution, the beneficial effects of this utility model are: 1. In this utility model, the cable sheath is stretched by rotating the winding roller. Compared with the traditional tensile testing device, the winding length can be adjusted to adapt to cable sheaths with different tensile properties. This solves the problem that the traditional device cannot effectively test high tensile performance sheaths due to insufficient stroke, and breaks through the testing limitations.

[0013] 2. In this utility model, by using a bevel gear transmission structure to drive the winding roller to rotate, and cooperating with a tension sensor to monitor the tension in real time, combined with the sliding cooperation between the clamping assembly and the guide rail assembly, the tensile performance of the cable sheath is accurately detected while ensuring the stability of the detection process, thereby improving the applicability and detection effect of the detection device.

Detailed Implementation

[0016] The technical solutions of the present invention will now be described in conjunction with the accompanying drawings of the embodiments thereof. like Figures 1-6 As shown, a cable sheath tensile performance testing device includes: a support base 1, a guide support 2 fixedly connected to the center of the top surface of the support base 1, and a slot opened inside the guide support 2, and a tensile sensor 201 fixedly connected inside the slot; A guide rod assembly 2011 is fixedly connected to the top surface of the tension sensor 201. The guide rod assembly 2011 has a cylindrical structure, and a guide rail assembly 2012 is fixedly connected to the top surface of the guide rod assembly 2011. The guide rail assembly 2012 is arranged horizontally, and a horizontal groove is opened inside the guide rail assembly 2012. A clamping push rod 2013 is fixedly connected inside the horizontal groove. There are two clamping push rods 2013, and a clamping assembly 2014 is fixedly connected to the inner side of each clamping push rod 2013.

[0017] The clamping assembly 2014 has sliders fixedly connected to both its front and rear sides, and the clamping assembly 2014 is slidably connected to the guide rail assembly 2012. The top surface of the support base 1 is fixedly connected to a column assembly 101, which is a cylindrical structure. There are four column assemblies 101, which are fixedly connected to the four corners of the top surface of the support base 1. The top surface of the four column assemblies 101 is also fixedly connected to a top plate assembly 1011.

[0018] Among them, the support base 1 and the column assembly 101 together form a support structure for the top plate assembly 1011, and the bottom end surface of the top plate assembly 1011 is fixedly connected to the upright plate mechanism 3. The upright plate mechanism 3 is perpendicular to the bottom end surface of the top plate assembly 1011. There are two upright plate mechanisms 3, and the two upright plate mechanisms 3 are fixedly connected to the front and rear sides of the bottom end surface of the top plate assembly 1011 in opposite directions. The front end surface of the upright plate mechanism 3 on the front side is also fixedly connected to the support plate assembly 301.

[0019] The inner side of the upright plate mechanism 3 is rotatably connected to a rotating shaft assembly 3013. A bevel gear B3014 is coaxially mounted at the front end of the rotating shaft assembly 3013. The bevel gear B3014 meshes with the bevel gear A3012 for transmission. A take-up roller 3015 is also fixedly connected to the outer side of the rotating shaft assembly 3013. A test piece 3017 with a protective sleeve structure is wound around the outer side of the take-up roller 3015. A fixing bolt 3016 for limiting the test piece 3017 is screwed onto the outer side of the take-up roller 3015. A servo motor 3011 is fixedly connected to the top surface of the support plate assembly 301. An output shaft is provided at the bottom end of the servo motor 3011, and a bevel gear A3012 is mounted on the output shaft.

[0020] In use, firstly, one end of the cable sheath to be tested (test piece 3017) is fixed to the take-up roller 3015 by the fixing bolt 3016, and the other end is placed between the two clamping components 2014 in the guide rail assembly 2012. Then, the clamping push rod 2013 is activated to push the two clamping components 2014 to slide relative to each other along the transverse groove of the guide rail assembly 2012. By utilizing the sliding cooperation of the sliders on the front and rear sides of the clamping components 2014 in the guide rail assembly 2012, the other end of the cable sheath is stably clamped. Then, the servo motor 3011 is started, and its output shaft drives the bevel gear A3012 to rotate. Since the bevel gear A3012 meshes with the bevel gear B3014, the bevel gear B3014 rotates with the bevel gear A3012 and drives the rotating shaft assembly 3013 to rotate inside the vertical plate mechanism 3, thereby causing the winding roller 3015 to rotate synchronously, winding up the cable sheath wrapped on its outer side and generating an upward pulling force. When the cable sheath is stretched, the tension is transmitted to the tension sensor 201 through the clamping assembly 2014, the guide rail assembly 2012, and the guide rod assembly 2011. The tension sensor 201 detects and records the tension value in real time. During this process, the support base 1 provides stable support to the top plate assembly 1011 through the column assembly 101. The upright plate mechanism 3 is fixed to the bottom surface of the top plate assembly 1011, providing a foundation for the installation and rotation of components such as the rotating shaft assembly 3013 and the winding roller 3015. The guide support 2 provides fixed support for the tension sensor 201, ensuring the stability of the position of each component and the effective transmission of force during the entire detection process.
