Description

Technical Field

[0001] The utility model relates to the technical field of power cord processing, and specifically relates to a tensile test device for power cord processing. Background Technique

[0002] A power cord is a wire for transmitting current. The structure of a power cord mainly includes an outer sheath, an inner sheath, and a conductor. Common transmission conductors are metal wires made of copper or aluminum. In some high-precision electrical appliances, materials such as silver and gold are also used as conductors. After the existing power cords are produced, it is necessary to detect their tensile strength.

[0003] A tensile test device for power cord processing disclosed in Chinese Patent with the publication number CN219201099U includes a main body device, and the main body device includes a support unit, a clamping unit, and a driving and detecting unit. The support unit includes a test bench. By using the cooperation of the first installation groove, the second installation groove, and the third installation groove formed in the four-part clamping plate installed in the fixed clamping frame, the device can perform tensile tests on power cords with different diameter specifications, thereby improving the practicability of the device.

[0004] In view of the above related technologies, there are some deficiencies in this device. During the tensile test of the power cord, the test area is completely exposed, which means that there are no protection measures for the power cord during the test. If there are quality problems with the power cord, during the pulling process, the power cord breaks, and a large elastic force or rebound force will be generated at the moment of fracture, which may cause harm to the staff around the device. Therefore, it is necessary to provide a tensile test device for power cord processing to solve the above technical problems. Content of the Utility Model

A support plate 25 is fixedly installed on the top of the adjusting block 13;

A driving mechanism is arranged above the inside of the protective cover 2 in front of the front of the activity plate 3.

[0034] The clamping mechanism 11 includes bearing plates 18, and the number of the bearing plates 18 is two. The two bearing plates 18 are respectively fixedly installed on the other side of the top of the substrate 1 and on the top of the support plate 25. The bearing plate 18 is fixedly installed with a fixing plate 26 through a support column installed on its top. An electric telescopic rod 19 is fixedly inserted through the top of the fixing plate 26. A pressing plate 22 is fixedly installed at the driving end of the electric telescopic rod 19. A plurality of upper convex strips 23 are fixedly installed at the bottom of the pressing plate 22. A plurality of lower convex strips 24 are fixedly installed on the top of the bearing plate 18, and the lower convex strips 24 and the upper convex strips 23 are arranged in a vertically staggered manner.

[0035] In one embodiment, the driving mechanism includes a rotating shaft 7, and the rotating shaft 7 is rotatably installed above the inside of the protective cover 2 in front of the front of the activity plate 3. A second motor 16 corresponding to the position of the rotating shaft 7 is fixedly installed on one side of the protective cover 2, and the driving end of the second motor 16 penetrates through one side of the protective cover 2 and extends into the inside of the protective cover 2 to be fixedly connected with one end of the rotating shaft 7.

[0036] In one preferred embodiment, a plurality of positioning rods 20 are fixedly installed on the top of the pressing plate 22. Positioning holes 21 corresponding to the position and quantity of the positioning rods 20 are opened on the top of the fixing plate 26, and the positioning holes 21 are slidably connected with the positioning rods 20, enabling the pressing plate 22 to move vertically stably.

[0037] In one embodiment, an explosion-proof glass 8 is fixedly installed on the activity plate 3 through a window opened on its front, facilitating the real-time monitoring of the processing situation.

[0038] In one of the preferred embodiments, a threaded hole adapted to the screw 12 is provided on one side of the adjusting block 13, and the adjusting block 13 is threadedly connected to the screw 12 through the threaded hole provided on one side thereof. A number of balls 14 are movably installed on the sliding contact surface between the adjusting block 13 and the slideway 9, and the balls 14 are in rolling contact with the inner wall of the slideway 9. Through the arrangement of the balls 14, the friction between the adjusting block 13 and the slideway 9 is greatly reduced, the efficiency of the first motor 10 is improved, and at the same time, the wear of the adjusting block 13 is reduced, making it more durable.

[0039] The working principle of the present utility model is as follows: all the electrical components mentioned in the text are electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer for control, and the existing publicly disclosed power connection technology will not be elaborated in the text. During use, first control the second motor 16 to start working. The driving end of the second motor 16 drives the rotating shaft 7 to rotate. The rotation of the rotating shaft 7 drives the gear 6 to rotate. Through the meshing of the gear 6 and the rack 5, the movable plate 3 moves vertically under the limitation of the fixed through groove 4. The movement of the movable plate 3 causes a sliding relationship between the limiting groove 15 and the limiting block 17. The cooperation of the limiting groove 15 and the limiting block 17 limits the vertical movement position of the movable plate 3. At this time, control the upward movement of the movable plate 3, and the movable plate 3 will lose the sealing effect on the front opening of the protective cover 2. At this time, the staff can put the power cord to be tested into the interior of the protective cover 2 from the front opening of the protective cover 2. Subsequently, fix the two ends of the power cord through two clamping mechanisms 11. Place the two ends of the power cord on the tops of the bearing plates 18 of the two clamping mechanisms 11 respectively, and then control the electric telescopic rod 19 to start working. The driving end of the electric telescopic rod 19 drives the pressing plate 22 to move vertically, so that the pressing plate 22 moves downward to clamp and fix the two ends of the power cord. Then control the movable plate 3 to move downward to close the front opening of the protective cover 2. Then control the first motor 10 to start working. The driving end of the first motor 10 drives the screw rod 12 to rotate. Through the screw drive of the screw rod 12 and the adjusting block 13, and the sliding relationship between the adjusting block 13 and the slideway 9, the adjusting block 13 moves horizontally stably. The movement of the adjusting block 13 drives the support plate 25 to move. The movement of the support plate 25 drives the clamping mechanism 11 on its top to move. At this time, one clamping mechanism 11 remains in the initial position and does not move. The clamping mechanism 11 located on the support plate 25 will move to the right to conduct a tensile test on the power cord. During the whole test process, the test area is enclosed on the top of the base plate 1 by a protective cover 2 and a movable plate 3, forming a fully enclosed protection system. In this way, even if the power cord breaks during the test, since the test area is completely enclosed, the reactions such as elasticity or the splashing of broken objects after the break are restricted inside the protective cover 2 and will not cause any harm to the external staff, thus significantly improving the safety of the device. After the power cord completes the test, control the movable plate 3 to move upward, and take out the power cord above the top of the base plate 1 through the front opening of the protective cover 2. In addition, during the use of this device, the opening and closing of the protective cover 2 and the fixing of the power cord are all mechanized operations without manual operation, which improves its use efficiency.

[0040] The above has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present utility model and are not used to limit the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
