DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Reference Figure 1-7 The wear resistance testing device for automobile ceiling fabric comprises a mounting platform 1, a testing platform 4 is arranged on the upper surface of the mounting platform 1, motors 2 are symmetrically arranged on the left and right sides of the testing platform 4 on the upper surface of the mounting platform 1, and clamping mechanisms 3 are assembled on the output ends of the motors 2 on both sides, and the motors 2 can drive the clamping mechanisms 3 to rotate.

[0026] In addition, the clamping mechanism 3 includes a connecting plate 33, one end of which is connected to the output end of the motor 2, and the other end of the connecting plate 33 away from the motor 2 is connected to a winding roller 31. A movable plate 32 is movably arranged above the connecting plate 33, and one end of the movable plate 32 is connected to a winding roller 31. The winding roller 31 on the movable plate 32 is symmetrical and fit together with the winding roller 31 on the lower connecting plate 33, and the winding rollers 31 on the upper and lower sides are fitted together to form a whole and then the car roof fabric is wound on it.

[0027] Among them, the winding roller 31 is semicircular, and blocking plates 311 are provided at both ends of the arc outer wall of the winding roller 31. A plurality of rubber strips 312 are evenly arranged laterally on the surface of the other side of the winding roller 31 away from the arc outer wall. A hollow cavity 313 is opened in the roller body of the winding roller 31. The hollow cavity 313 is convenient for reducing the weight of the winding roller 31, so that the connecting plate 33 will not be broken due to the heavier winding roller 31.

[0028] In addition, a screw rod 333 is vertically arranged on the upper surface of the connecting plate 33, and a fixing component 10 is screwed on the screw rod 333. A rubber block 332 is arranged on the upper surface of the connecting plate 33 on one side of the fixing component 10. The rubber block 332 can prevent the fixing component 10 from over-pressing the movable plate 32, thereby playing a limiting role.

[0029] Among them, a sliding rod 331 is symmetrically arranged on the upper surface of the connecting plate 33, which is located on the side of the rubber block 332 away from the screw rod 333. The movable plate 32 is slidingly fitted on the sliding rod 331. The movable plate 32 has sliding holes 321 symmetrically extending therethrough. A through hole 332 is opened on the plate body of the movable plate 32, which is located on one side of the sliding hole 321. The through hole 332 is used to prevent the movable plate 32 from being restricted by the screw rod 333.

[0030] Among them, the aperture of the through hole 332 is larger than the major diameter of the screw 333, the screw 333 is arranged in the through hole 33, and the fixing component 10 is screwed on the screw 333 located above the movable plate 32, and the fixing component 10 is used to press the movable plate 32, thereby pressing the winding roller 31 on the movable plate 32 onto the winding roller 31 on the connecting plate 33, so that the two winding rollers 31 clamp the car roof fabric.

[0031] In addition, an optical orientation meter 9 is provided at one side of the rear end of the detection platform 4. The optical orientation meter 9 is a prior art and is an instrument that can be used to measure tensioned fabrics. Its principle is to determine the tension of the fabric by measuring the light reflection ability of the fabric. Before the measurement, the fabric should be fixed on the optical orientation meter and calibrated according to the instructions for use. The optical orientation meter is well known to those in the field of fabric tension detection, and its structure and principle need not be elaborated.

[0032] Among them, a mounting frame 5 is arranged on the upper surface of the mounting table 1 in the middle of the detection platform 4, a moving seat 6 is slidably arranged on the upper end frame of the mounting frame 5, a servo electric cylinder 8 is installed on the moving seat 6, and a grinding head assembly 8 is installed at the end of the piston rod at the bottom output end of the servo electric cylinder 8. The grinding head assembly 8 is used to detect wear resistance.

[0033] In this embodiment, when the wear resistance of the automobile roof fabric is tested and compared to select the most suitable fabric, the present detection device can be used. First, the automobile roof fabric is positioned and clamped to the clamping mechanisms 3 on both sides. First, the fixing component 10 is loosened from the screw 333, and then the winding rollers 31 that were originally attached together are separated. The movable plate 32 slides on the slide bar 331 to separate the upper and lower winding rollers 31. At this time, the side of one end of the automobile roof fabric can be placed between the upper and lower winding rollers 31, and then the movable plate 32 is lowered to press the upper winding roller 31 down, thereby pressing the automobile roof fabric tightly. The rubber strip 312 can play a good role in increasing friction to prevent the automobile roof fabric from detaching. Then the movable plate 32 is resisted by the rubber block 332, and the rubber block 332 plays a good limiting role. The fixing component 10 is rotated downward on the screw 333 so that the fixing component 10 presses the movable plate 32 on the rubber block 332.

[0034] At this time, after the clamping mechanism 3 on one side installs the car roof fabric, the clamping mechanism 3 on the other side clamps the side edge of the other end of the car roof fabric in the same way, and then the motors 2 on both sides rotate, and the combined winding roller 31 will wind the car roof fabric on the arc outer wall of the winding roller 31, and then the winding rollers 31 on both sides wind up in opposite directions at the same time, so that the originally loose car roof fabric is slowly tightened, and then the tightened car roof fabric is more convenient for the grinding head assembly 8 to rub, and the loose car roof fabric will produce wrinkles, which will cause the grinding head assembly 8 to have a poor effect when rubbing, and the optical orientation instrument 9 can be used to detect the tension of the car roof fabric after tightening, so as to ensure that car roof fabrics of different materials are clamped, and all the car roof fabric tension fingers can be ensured to be close by the rotation of the motor 2, thereby ensuring the accuracy of the detection.

[0035] After the car roof fabric is installed, the servo electric cylinder 7 can be driven to lower the grinding head assembly 8 so that the grinding head assembly 8 can contact the surface of the car roof fabric and the bottom is attached to the upper surface of the detection platform 4, and then the moving seat 6 moves back and forth on the mounting frame 5, so that the grinding head assembly 8 can rub back and forth on the car roof fabric, and then the wear degree of different car roof fabrics under the same number of frictions is compared to find the one with the best wear resistance.

[0036] In the utility model, the automobile roof fabric is clamped and positioned by the provided clamping mechanism 3, the provided winding roller 31 can effectively wind up the automobile roof fabric, and can also adjust the tension value of the automobile roof fabric by tightening with the motor 2, thereby effectively tightening the automobile roof fabric, making it more convenient for the grinding head assembly 8 to rub, and cooperating with the optical orientation instrument 10 to ensure that the detected tension values ​​of the automobile roof fabric are all detected in a close state, thereby improving the accuracy of the detection.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
