Summary of the invention
The utility model is for solving the problems referred to above that prior art exists; Provide a kind of cable tube to use the impact test machine; The shock resistance of test cable pipe exactly; For cable tube provides the unified shock resistance method of inspection and unified evaluation foundation, be convenient to cable tube factory control product quality.
The purpose of the utility model realizes through following technical scheme:
A kind of cable tube is used the impact test machine, it is characterized in that, testing machine comprises base plate, drift, two guide rods, weight, weight positioning disk, movable head, backstay, top board; Described two guide rods are vertically set on the left and right sides of base plate respectively; The lower end of two guide rods is connected with base plate, and the upper end of two guide rods is connected with a horizontally disposed top board left and right sides, said movable head a vertical through holes each side arranged; Have on the sidewall of vertical through holes and laterally hold out against screw; Movable head passes through two vertical through holes kinks on two guide rods, and is fastened on two guide rods through laterally holding out against screw with puller bolt, and said weight positioning disk is fixed by the bottom center of movable head; Respectively there is a through hole at the center of said top board, movable head and weight positioning disk; Said backstay vertically passes the through hole at top board, movable head and weight positioning disk center, and the upper end of said backstay is fixed on the top board, and the drift end face is provided with the jack that inserts the backstay lower end; The said weight of kink on the backstay, weight is between drift and weight positioning disk.
Improvement to technique scheme: the bottom surface that described drift contacts with sample is a sphere, and sphere curvature radius is 40-60mm.
Further improvement to technique scheme: described weight positioning disk is electromagnetic disc or permanent magnet dish, and the material of said weight is an iron.
The advantage and the good effect of the utility model are:
The cable tube of the utility model is used the impact test machine, falls to directly impacting the cable tube sample by the drift sphere through the control weight, can carry out impact test with different height of the falls to different cable tubes through the weight of selecting Different Weight.The shock resistance of test cable pipe for cable tube provides the unified shock resistance method of inspection and unified evaluation foundation, is convenient to cable tube factory control product quality exactly.It is simple in structure, easy to operate, and weight falls to having guaranteed experimental safe along backstay.
Description of drawings
Fig. 1 is the structural drawing of a kind of cable tube of the utility model with the impact test machine.
Embodiment
Referring to Fig. 1, a kind of cable tube of the utility model is with the embodiment of impact test machine, mainly is made up of base plate 1, drift 2, two guide rods 3, weight 4, weight positioning disk 5, movable head 6, backstay 8, top boards 9.Described two guide rods 3 are vertically set on the left and right sides of base plate 1 respectively; The lower end of two guide rods 3 is connected with base plate 1; The upper end of two guide rods 3 is connected with a horizontally disposed top board 9 left and right sides, said movable head 6 a vertical through holes each side arranged, have on the sidewall of vertical through holes laterally to hold out against screw; Movable head 6 passes through two vertical through holes kinks on two guide rods 3, and is fastened on two guide rods 3 through laterally holding out against screw with puller bolt 7.Said weight positioning disk 5 is fixed by the bottom center of movable head 6; Respectively there is a through hole at the center of said top board 9, movable head 6 and weight positioning disk 5; Said backstay 8 vertically passes the through hole at top board 9, movable head 6 and weight positioning disk 5 centers, and the upper end of said backstay 8 is provided with the jack that inserts backstay 8 lower ends through being bolted on the top board 9 on drift 2 end faces; The said weight 4 of kink on the backstay 9, weight 4 is between drift 2 and weight positioning disk 5.
On described two guide rods 3 height gauge 10 is arranged, the bottom surface that described drift 2 contacts with sample is a sphere, and its sphere curvature radius is 40-60mm.Weight positioning disk 5 is the permanent magnet dish, and the material of weight 4 should be iron, copper equimagnetic inductive material.Described weight positioning disk 5 also can be an electromagnetic disc.
