Description
Technical Field
[0001] This utility model relates to the field of power tool technology, and in particular to an electric cable grinder. Background Technology
[0002] In the production, repair, and wiring of cables, it is often necessary to grind the cable insulation layer or surface. For example, when making cable heads, to ensure the effectiveness of the wiring and electrical connections, the cable insulation layer needs to be ground to the appropriate size and flatness for easy installation of the cable head. Currently, common cable grinding methods have many problems. Manual grinding with sandpaper is not only inefficient, consuming a lot of manpower and time, but also produces cable parts with low precision, poor consistency, and a low yield. Some existing electric grinding equipment also suffers from drawbacks such as complex structure, difficulty in control, low grinding precision, and inability to meet the grinding requirements of cables of different specifications. For example, some grinding equipment can only grind one side of the cable, making it difficult to achieve uniform grinding of the entire cable ring surface, resulting in unsatisfactory grinding effects and affecting the subsequent performance of the cable. Therefore, there is a need to propose an electric cable grinding machine. Utility Model Content

The output end of the motor 23 can drive the drive wheel 21 to rotate. The rotation of the drive wheel 21 can cooperate with the other drive wheel 21 to drive the sanding belt 22, thereby rotating the sanding belt 22 and thus grinding the cable.
[0027] In this embodiment, when using this device, the cable to be ground is first placed inside the through hole 7. Then, the knob 13 is rotated, which drives the bidirectional screw 14 to rotate. The rotation of the bidirectional screw 14 drives the two threaded blocks 15 to move closer or further apart, thereby driving the two clamping blocks 16 to clamp and fix the cable. This allows cables of different sizes to be clamped and fixed. After clamping and fixing, the motor 10 can be started. The output end of the motor 10 drives the gear 11 to rotate. The rotation of the gear 11 drives the gear ring 8 to rotate. The rotation of the gear ring 8 drives the turntable 6 to rotate. The rotation of the turntable 6 drives the cable clamped and fixed by the two clamping blocks 16 to rotate. Simultaneously, motor 17 operates, driving a one-way screw 3 to rotate via its output. The rotation of the one-way screw 3 causes the threaded block 4 to move along the one-way screw 3, thus enabling comprehensive and uniform grinding of the cable. While the cable moves and rotates, motor 3 operates, driving a two-way screw 18 to rotate via its output. The rotation of the two-way screw 18 causes two threaded blocks 19 to move closer to each other, thereby causing two T-shaped frames 20 to move closer to each other, which in turn causes two sanding belts 22 to clamp the cable between them. Then, motor 4 operates, driving a transmission wheel 21 and sanding belts 22 via its output, thus grinding the cable.
