Description

Technical Field

[0001] This utility model relates to the field of cable testing technology, and in particular to a calibration table for precise inspection of cable surface finish. Background Technology

[0002] A cable is an electrical or signal transmission device, usually composed of several or several groups of conductors. An outer sheath is installed on the outside of the cable. After the cable is manufactured, it is inspected for cracks or damage to the cable sheath. Generally, the cable is placed on a testing platform to observe whether the cable is damaged. This calibration platform is used to inspect the surface smoothness of the cable.

[0025] The material conveying assembly comprises a rectangular cavity 9 formed in the rear end wall of the rack 1, a driving gear 10 rotatably connected to the center of the cavity 9, and two driven gears 11 symmetrically arranged near the two sides of the driving gear 10 and rotatably connected to the end wall of the cavity 9. The driving gear 10 and the driven gears 11 are in gear meshing. The material conveying assembly further comprises a transmission shaft 12 fixed to the front center end wall of the driving gear 10 and the driven gears 11, a fixed buckle 13 fixed to the front end wall of the transmission shaft 12 on the front side of the driven gears 11, a motor 14 drivingly connected to the end of the transmission shaft 12 on the front side of the driving gear 10, a material roller 15 arranged on the end wall of the fixed buckle 13 for winding and unwinding the cable, and a roller buckle opening 16 formed in the end wall of the material roller 15 for clamping the fixed buckle 13.

[0026] A docking port 17 is formed in the center of the upper end wall of the rack 1. The docking port 17 is clamped with a docking seat 20. A pair of rectangular docking plates 18 are vertically fixed to the upper end of the docking seat 20. A pulling wheel 19 for pulling and redirecting the cable is rotatably connected to the top end wall of the docking plate 18.

[0027] Working principle:

[0028] In the material conveying assembly, the cavity 9 is used to install and rotatably connect a driving gear 10 and two driven gears 11. One driving gear 10 is driven to rotate by the motor 14. The two driven gears 11 are driven to rotate in the same direction by gear meshing. The front end of each driven gear 11 is fixed with a fixed buckle 13 through a transmission shaft 12. The fixed buckle 13 is clamped with the roller buckle opening 16 for disassembling and assembling the material roller 15. When the material roller 15 is used, it is assembled on the front side of the driven gear 11. When it is idle or needs to be replaced, the material roller 15 is disassembled from the front side of the driven gear 11. The two material rollers 15 are designed for feeding and winding the cable. When in use, the cable is guided and pulled along the moving roller 7. The cable is spread on the rack 1, which has better neatness and prevents the cable from being piled up and connected together, which affects the observation effect of the skin.

[0029] The rotating column 5 is rotated to rotate the side plate 6, thereby changing the height position of the moving roller 7. The height of the moving roller 7 can be controlled and adjusted when pulling the cable. The angle and height position of the cable being pulled are changed. The screw 8 is tightened, the screw 8 penetrates the threaded hole in the end wall of the rotating column 5, and the rotating column 5 and the side plate 6 are limited. The height-adjusted moving roller 7 is further limited. The moving roller 7 is stably used for pulling the cable after adjusting the height.

[0030] The material conveying assembly conveys and winds the cable. The cable is sequentially displaced and transported along the two moving rollers 7. The cable is sequentially and alternately arranged in the upper end region of the rack 1.

[0031] When the cable is pulled, a section of the cable is spread out at the upper end region of the rack 1, at which time the flatness, damage and rupture of the surface of the cable can be manually observed and detected, and at the same time, the cable surface defect detector of the prior art can be placed at the upper end of the rack 1 to intelligently detect the cable part;

[0032] During detection, the interface 17 can be clamped to the docking seat 20, and a pair of docking plates 18 fixed to the docking seat 20 are rotatably connected to a pulling wheel 19, which is used to pull the cable to form a large height difference between the cable and the two movable rollers 7, so that when the cable is pulled through the pulling wheel 19, the turning is obvious, the bending degree of the cable surface near the pulling wheel 19 is large, and when the cable surface has damage, the damage and rupture of the cable surface are more obvious in the pulling bending state, so as to better identify the damage of the cable surface;

[0033] Among them, the clamping of the docking interface 17 and the docking seat 20 facilitates the disassembly and assembly of the pulling wheel 19, and the use or disassembly of the pulling wheel 19 is more flexible and convenient;

[0034] The guide wheel 4 at the rack 1 is designed to assist the movable roller 7 in pulling the cable.

[0035] The above shows and describes the basic principle, main features and advantages of the present application. It should be understood by those skilled in the art that the present application is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the present application. The scope of protection required by the present application is defined by the appended claims and their equivalents.
