Description

Technical Field

[0001] This utility model relates to the field of cable cutting machines, and in particular to a quick-change mechanism for the cutter wheel of a cable cutting machine. Background Technology

[0002] A cable cutting machine is a device specifically designed for cutting cables. It is mainly used to cut long cables into segments of the required length and is widely used in various scenarios that require precise cable cutting, such as wire and cable manufacturing, hardware processing, automotive parts processing, and electronic component processing.

[0003] The cutter wheel is an important component of a cable cutting machine. It usually achieves cutting by rotating the cutting blade. Since the types of cables to be cut are different and the cutter wheel is a consumable part that needs to be replaced regularly, it often involves the disassembly and replacement of the cutter wheel. The existing cutter wheel usually requires fixing the mounting base during the disassembly and replacement process, and then disassembling and assembling the bolts to achieve the replacement of the cutter wheel.

[0004] However, the existing cable cutting machine mounting base is inconvenient to fix and can easily affect the tightening of bolts. At the same time, the cutter wheel lacks a pre-fixing structure during installation, which makes the switching of the cutter wheel time-consuming and labor-intensive, resulting in low efficiency.

[0013] Preferably, the rear side of the adjusting seat has a threaded hole, the lead screw is threaded to the inner side of the threaded hole, and the rear end of the lead screw extends to the outer side of the adjusting seat and a knob is fixedly installed thereon.

[0014] The beneficial effects of this utility model are:

[0015] The cable cutting machine's quick-change mechanism for the cutter wheel works by rotating a lead screw to control a moving block to slide inside the adjusting seat until the ball bearings abut against the mounting seat. By rotating the mounting seat, when the engaging hole aligns with the movable rod, the movable rod inserts into the engaging hole, thus fixing the mounting seat. At this point, tightening the fixing bolts releases the clamping seat and the cutter wheel body, facilitating their removal. The cutter wheel body to be switched is then fitted onto the outside of the boss, and the clamping seat is fitted onto the outside of the boss. Through the cooperation of the elastic buckle and the engaging groove, the clamping seat and the cutter wheel body are pre-installed and fixed, facilitating the installation of the fixing bolts and enabling the switching of the cutter wheel body.

[0025] Please see Figures 2-5 In this embodiment, the movable rod 11 and the inner side of the sleeve 10 are slidably connected. The rear end of the movable rod 11 and the inner side of the sleeve 10 are elastically connected by a spring. The front end of the movable rod 11 extends to the inner side of the protective cover 2 through a sliding hole. The side of the mounting base 3 is provided with a locking hole 31. The front end of the movable rod 11 and the inner side of the locking hole 31 are mutually adapted. The moving block 9 and the inner side of the adjusting seat 8 are slidably connected.

The rear side of the adjusting seat 8 is provided with a threaded hole. The lead screw 13 is threadedly connected to the inner side of the threaded hole. A knob 131 is fixedly installed on the outer side of the rear end extending to the adjusting seat 8. By rotating the screw 13 through the knob 131, the moving block 9 slides inside the adjusting seat 8. The sleeve 10 drives the movable rod 11 to approach the mounting seat 3 until the ball 12 abuts against the mounting seat 3. By rotating the mounting seat 3, the ball 12 rolls in cooperation. When the locking hole 31 is aligned with the movable rod 11, the movable rod 11 is inserted into the locking hole 31 under the elastic force of the spring, thus fixing the mounting seat 3. At this time, the fixing bolt 7 is turned to release the fixing of the clamping seat 6 and the cutter wheel body 5, making it convenient to remove the clamping seat 6 and the cutter wheel body 5.

[0026] During operation, the screw 13 is rotated by the knob 131 to control the sliding block 9 to slide inside the adjusting seat 8. The sleeve 10 drives the movable rod 11 to approach the mounting seat 3 until the ball bearing 12 abuts against the mounting seat 3. By rotating the mounting seat 3, the ball bearing 12 rolls in cooperation. When the locking hole 31 aligns with the movable rod 11, the movable rod 11 is inserted into the locking hole 31 under the elastic force of the spring, thus fixing the mounting seat 3. At this time, the fixing bolt 7 is turned to release the fixing of the clamping seat 6 and the cutter wheel body 5, making it easy to remove the clamping seat 6 and the cutter wheel body 5. By sleeve the switched cutter wheel body 5 on the outside of the boss 4, and then sleeve the clamping seat 6 on the outside of the boss 4, the clamping seat 6 and the cutter wheel body 5 are pre-installed and fixed through the cooperation of the elastic buckle 14 and the locking groove 61, which facilitates the installation of the fixing bolt 7 and realizes the switching of the cutter wheel body 5.

When the mounting base 3 is rotated and the locking hole 31 is aligned with the movable rod 11, the movable rod 11 is inserted into the locking hole 31 to fix the mounting base 3. The switchable cutter wheel body 5 is sleeved on the outside of the boss 4, and then the clamping seat 6 is sleeved on the outside of the boss 4. Through the cooperation of the elastic buckle 14 and the locking groove 61, the clamping seat 6 and the cutter wheel body 5 are pre-installed and fixed, which facilitates the installation of the fixing bolt 7. This solves the problem that the mounting base of the cable cutting machine is inconvenient to fix and easily affects the tightening of the bolts. At the same time, the lack of a pre-fixing structure during the installation of the cutter wheel leads to the time-consuming and labor-intensive switching of the cutter wheel and the low efficiency.
