Description

Technical Field

[0001] The utility model relates to the field of cable detection, in particular to a cable wear resistance detection device. Background Art

[0002] After the cable is produced and processed, its wear resistance needs to be tested to avoid the phenomenon of easy wear of the cable after it is put on the market. A wear resistance detection device for cable processing is disclosed in the Chinese utility model patent with announcement number CN218382214U. The staff moves upward by holding the pressure rod tightly. The pressure rod drives the sliding plate to move upward on the positioning rod to clamp the cable. The staff starts the motor, and the grinding wheel rotates to rub the cable sheath, thereby continuously testing the wear resistance of the cable. In the above structure, the cable is placed in the groove above the sliding plate and moves up to contact the grinding wheel under the action of the spring. The spring will produce elastic fatigue after long-term use, and its elasticity will decrease, which will reduce the pressure between the cable and the grinding wheel, and then cause different test results for the same cable, which will cause deviations in the test results. To this end, we designed a cable wear resistance detection device. Utility Model Content

[0003] In order to solve the technical problem that the detection results of the same cable are different, the utility model provides a cable wear resistance detection device.

[0004] The utility model is implemented by the following technical scheme: a cable wear resistance detection device, comprising a base, a machine table and a fixed plate are respectively installed on the left and right sides above the base, a rotating shaft is rotatably installed between the machine table and the fixed plate through a bearing, two symmetrically arranged grinding wheels are installed on the rotating shaft, an upper fixed component is arranged above the grinding wheel, and a lower fixed component is arranged below the grinding wheel, a cable is tensioned between the upper fixed component and the lower fixed component, and the cable contacts the front side of the outer ring surface of the grinding wheel.

[0005] As a further improvement of the above scheme, the upper fixing assembly includes a mounting plate installed horizontally above the machine table and the fixing plate, two symmetrically distributed support frames are arranged above the mounting plate, an adjusting screw is threadedly connected to the top of the support frame, the lower end of the adjusting screw passes through the support frame and is placed below it, and the bottom end of the adjusting screw is rotatably connected to a clamping plate, the cable is placed between the mounting plate and the clamping plate, and then the adjusting screw is rotated to make the cable tightly pressed between the mounting plate and the clamping plate, so that it can be fixed, and it is suitable for cables of various diameters;

[0006] The structural composition of the lower fixed component is consistent with that of the upper fixed component, and the lower fixed component is designed vertically to the upper fixed component. When testing the cables, the length of each cable is ensured to be the same, and the length of the cable at the rear side of the upper fixed component and the part below the lower fixed component is the same, which can ensure that the resistance between each cable and the grinding wheel is the same, thereby ensuring the accuracy of the detection.

[0007] As a further improvement of the above scheme, the upper fixing assembly is located at a rear position above the grinding wheel, and the lower fixing assembly is located at a rear position below the grinding wheel. After the cable is fixed between the upper fixing assembly and the lower fixing assembly, the cable can contact the front side of the outer ring surface of the grinding wheel, thereby facilitating friction therewith, thereby enabling wear resistance testing;

[0008] The multiple corners of the mounting plate are all chamfered, and the multiple corners of the clamping plate are all chamfered, so that the outer surface of the cable will not contact the mounting plate and the clamping plate and cause scratches. The left and right sides of the clamping plate are in sliding contact with the left and right ends of the inner wall of the support frame, which can limit the clamping plate so that it can only move in a straight line.

[0009] As a further improvement of the above scheme, the rotating shaft includes a rotating head one and a rotating head two, and the rotating head one and the rotating head two are respectively rotatably mounted on the fixed plate and the machine platform through bearings. The rotating head one and the rotating head two are both provided with mounting grooves, and a mounting shaft is rotatably mounted in the mounting groove of the rotating head one through an axle pin. The mounting shaft is placed in the mounting groove of the rotating head two, and the two are fixed by bolts. By unscrewing the bolts, the mounting shaft can be deflected upward with the axle pin as the axle pin, thereby facilitating the replacement of the grinding wheel on the mounting shaft.

[0010] As a further improvement of the above scheme, the grinding wheel is slidably sleeved on the mounting shaft, and the two are fixed by screws, which facilitates the replacement of the grinding wheel, ensures the frosting degree of the grinding wheel surface, and facilitates accurate cable detection.

[0011] As a further improvement of the above scheme, the right end of the rotating head one passes through the fixed plate and is placed on the right side thereof, and the rotating head one is connected to the output shaft of the driving motor through a pulley and a belt. The rotation of the output shaft of the driving motor can cause the rotating shaft to rotate, and then the grinding wheel can rotate and rub the cable surface, thereby detecting its wear resistance.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The utility model arranges upper fixing components and lower fixing components at the rear positions of the upper and lower sides of the grinding wheel, thereby facilitating the quick fixing of the cable, and the surface of the cable can contact the surface of the grinding wheel, so that the wear resistance test can be performed on the cable, and the utility model is suitable for cables of various diameters, and can also ensure that the resistance between each cable and the grinding wheel is the same, thereby ensuring the accuracy of the detection;

[0014] The rotating shaft is divided into three parts: rotating head 1, mounting shaft and rotating head 2. The grinding wheel is installed on the mounting shaft. The grinding wheel can be quickly replaced, ensuring the grinding degree of the grinding wheel surface, which is convenient for accurate cable detection.

[0015] Two grinding wheels are arranged on the installation shaft, and two groups of upper fixing components and lower fixing components are arranged, so that two cables can be tested at the same time, and comparative testing can be performed, so as to observe the wear resistance of different cables.

It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0026] The upper fixing assembly 5 includes a mounting plate 51 installed horizontally above the machine table 2 and the fixing plate 3. Two symmetrically distributed support frames 52 are arranged above the mounting plate 51. An adjusting screw 54 is threadedly connected to the support frame 52. The lower end of the adjusting screw 54 passes through the support frame 52 and is placed below it. The bottom end of the adjusting screw 54 is rotatably connected to a clamping plate 53. The cable is placed between the mounting plate 51 and the clamping plate 53. After that, the adjusting screw 54 is rotated to make the cable tightly pressed between the mounting plate 51 and the clamping plate 53, so that it can be fixed. It is suitable for cables of various diameters.

[0027] The structural composition of the lower fixing component 8 is consistent with that of the upper fixing component 5, and the lower fixing component 8 is designed vertically to the upper fixing component 5. When testing the cables, the length of each cable is ensured to be the same, and the length of the cable at the rear side of the upper fixing component 5 and the part below the lower fixing component 8 is the same, which can ensure that the resistance between each cable and the grinding wheel 7 is the same, thereby ensuring the accuracy of the detection.

[0028] The upper fixing assembly 5 is located at a rear position above the grinding wheel 7, and the lower fixing assembly 8 is located at a rear position below the grinding wheel 7. After the cable is fixed between the upper fixing assembly 5 and the lower fixing assembly 8, the cable can contact the front side of the outer ring surface of the grinding wheel 7, thereby facilitating friction therewith, thereby enabling wear resistance testing;

[0029] Multiple corners of the mounting plate 51 are designed with rounded corners, and multiple corners of the clamping plate 53 are designed with rounded corners, so that the outer surface of the cable will not contact the mounting plate 51 and the clamping plate 53 and cause scratches. The left and right sides of the clamping plate 53 are in sliding contact with the left and right ends of the inner wall of the support frame 52, which can limit the clamping plate 53 and enable it to move only in a straight line.

[0030] The rotating shaft 6 includes a rotating head 1 61 and a rotating head 2 63. The rotating head 1 61 and the rotating head 2 63 are respectively rotatably installed on the fixed plate 3 and the machine table 2 through bearings. The rotating head 1 61 and the rotating head 2 63 are both provided with a mounting groove 611. The mounting shaft 62 is rotatably installed in the mounting groove 611 of the rotating head 1 61 through an axle pin. The mounting shaft 62 is placed in the mounting groove 611 of the rotating head 2 63, and the two are fixed by bolts. By unscrewing the bolts, the mounting shaft 62 can be deflected upward with the axle pin as the axle pin, thereby facilitating the replacement of the grinding wheel 7 on the mounting shaft 62.

[0031] The grinding wheel 7 is slidably sleeved on the mounting shaft 62, and the two are fixed by screws, so that the grinding wheel 7 can be easily replaced, the frosting degree of the surface of the grinding wheel 7 is guaranteed, and the cable can be accurately detected.

[0032] The right end of the rotating head 61 passes through the fixed plate 3 and is placed on its right side, and the rotating head 61 is connected to the output shaft of the driving motor 4 through a pulley and a belt. The rotation of the output shaft of the driving motor 4 can rotate the rotating shaft 6, and then the grinding wheel 7 can rotate and rub the surface of the cable, thereby detecting its wear resistance.

[0033] The implementation principle of a cable wear resistance detection device in the embodiment of the present application is as follows: in actual use, the upper end of the cable is inserted between the mounting plate 51 and the clamping plate 53 in the upper fixing component 5 and the adjusting screw 54 is rotated, so that the upper end of the cable is fixed in the upper fixing component 5, and the outer surface of the cable is attached to the front side of the outer ring surface of the grinding wheel 7, and then the lower end of the cable is inserted between the mounting plate 51 and the clamping plate 53 in the lower fixing component 8, and the lower end of the cable is fixed in the lower fixing component 8 in the same manner as described above. At this time, the power supply of the driving motor 4 can be turned on, so that the rotating shaft 6 drives the grinding wheel 7 to rotate, and the rotating grinding wheel 7 will rub the surface of the cable, thereby wearing the surface of the cable, and the wear resistance thereof can be detected;

[0034] When the surface of the grinding wheel 7 is worn, the bolts in the second rotating head 63 are removed, and then the screws on the grinding wheel 7 are removed, and the mounting shaft 62 is deflected upward with the shaft pin as the shaft pin, so that the left end of the mounting shaft 62 can be separated from the second rotating head 63, and the grinding wheel 7 can be removed and replaced with a new one;

[0035] By arranging the upper fixing assembly 5 and the lower fixing assembly 8 at the rear position on the upper and lower sides of the grinding wheel 7, the cable can be quickly fixed, and the surface of the cable can contact the surface of the grinding wheel 7, so that the wear resistance test can be performed on it, and it is suitable for cables of various different diameters, and it can also ensure that the resistance between each cable and the grinding wheel 7 is the same, thereby ensuring the accuracy of the detection;

[0036] The rotating shaft 6 is divided into three parts: a rotating head 1 61, a mounting shaft 62 and a rotating head 2 63. The grinding wheel 7 is mounted on the mounting shaft 62. The grinding wheel 7 can be quickly replaced, ensuring the frosting degree of the surface of the grinding wheel 7, which is convenient for accurate cable detection.

[0037] Two grinding wheels 7 are arranged on the installation shaft 62, and two groups of upper fixing components 5 and lower fixing components 8 are arranged, so that two cables can be tested at the same time and comparative testing can be performed, so as to observe the wear resistance of different cables.

[0038] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention.
