[0011] In order to make the purpose, technical scheme and advantages of the utility model more clear and intelligible, the utility model will be further described in detail below through the drawings and examples. However, it should be understood that the specific examples described herein are only used to explain the utility model and are not used to limit the scope of the utility model.
[0012] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the utility model belongs. The terminology used in the description of the utility model herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model.
[0013] As shown in Figure 1 , Figure 2 A novel cable cutting resistance testing machine, comprising a test bench; the test bench is provided with a horizontal testing device and a vertical testing device;
[0014] The horizontal testing device comprises a horizontal servo motor 7 and a lead screw sliding table 8; the lead screw sliding table 8 is connected with the moving platform 6; the moving platform 6 is used for fixing the test cable 5; a pressure sensor 9 is arranged between the lead screw sliding table 8 and the moving platform 6;
[0015] The vertical testing device comprises a vertical servo motor 1, a lead screw sliding table 2 and a test cone head 4; the test cone head 4 is installed on the lead screw sliding table 2; a pressure sensor 3 is arranged on one side of the test cone head 4; the pressure sensor 3 is installed on the lead screw sliding table 2.
[0016] Main working principle:
[0017] A movement process: the test cone head and the pressure sensor are both fixedly installed on the sliding table. The lead screw sliding table is moved up and down through the servo motor.
[0018] B vertical testing process: the test cone head is fixed below the pressure sensor, and the test cable is placed on the moving platform (there is a notch on the platform, and the cable can be freely positioned); when the test cone head just contacts the uppermost part of the cable (when the pressure sensor value is just greater than zero), the current position can be recorded through the servo motor (the position of the just contact is set as zero position); with the sliding table moving downward, the pressure value and the displacement value change simultaneously, and a numerical relationship is generated.
[0019] And the relevant data are recorded.
[0020] C horizontal testing process: when the vertical servo motor moves to the set depth position, the horizontal servo motor starts to move at this time, with the platform (the measured cable) moving together, the test cone head generates a pressure value and displacement value change relationship on the outer sheath of the cable.
[0021] The relevant data are recorded and the test is ended.
[0022] The device provides significant parameters for improving product quality and provides theoretical data for improving the cutting resistance of the cable sheath.
[0023] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement or improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
