Description

Technical Field

[0001] The utility model belongs to the technical field of wire welding rod production equipment, and particularly relates to a fixing device for a wire welding rod coil. Background Art

[0002] At present, the operation content of the existing workshop layer winding process includes the following steps: winding the wire welding rod until the coil is full, then cutting the wire welding rod; using a wrench to loosen the nut and then removing the nut by hand; removing the coil filled with the wire welding rod, and then installing an empty coil on the wire winding shaft; installing a baffle plate, screwing the screw by hand for several turns and then tightening it with a wrench, and continuing to repeat the wire winding. Since manual operation is generally adopted, the efficiency is low.

[0003] The existing Chinese utility model patent with the application number CN201821647852.X provides a wire welding rod coil automatic rotation and positioning device, which includes a base. Both the front and rear sides of the top of the base are fixedly installed with linear slide rails through bolts. The tops of the two linear slide rails are clamped and slidably connected to the bottom of a sliding plate. The left and right ends of the bottom of the base are fixedly installed with rodless cylinders through bolts. A moving block is slidably connected to the outer wall of the rodless cylinder, and the moving block is fixedly connected to the front side wall of the sliding plate through bolts. Both the left and right ends of the top of the sliding plate are fixedly installed with support plates through bolts. This kind of wire welding rod coil automatic rotation and positioning device is reasonably designed, easy to operate, has high production efficiency, and reduces the labor cost.

[0004] However, the existing positioning device lacks central limit for the wire welding rod coil, and since there is no distinction between the driving and driven turntables, when driving the wire welding rod coil to rotate for layer winding, the rotation stability of the wire welding rod coil is not good, which is not conducive to improving the layer winding effect of the wire welding rod. In addition, the existing positioning device lacks limit fixation for the wire welding rod coil. After the wire welding rod coil is layer wound, when performing operations such as wire welding rod cutting or bending, the stability of the wire welding rod coil is not good, which is also not conducive to improving the layer winding effect of the wire welding rod.

[0032] The above-mentioned driving disc mechanism includes a driving turntable 2 rotatably arranged on a machine tool body 1 and a power assembly 6 for driving the driving turntable 2 to rotate. One end of the driving turntable 2 facing the driven disc mechanism is provided with a driving shaft 3 that can cooperate with a wire spool, and a pull stud 4 is arranged on the driving shaft 3. Exemplarily, the driving turntable 2 can be rotatably installed on the machine tool body 1 through a bearing.

[0034] The above-mentioned driven disc mechanism includes an equipment rack 9 slidably arranged on the machine tool body 1 and a driven turntable 5 rotatably arranged on the equipment rack 9.

The disc spring is sleeved outside the connecting member 17, with one end abutting against the driven turntable 5 and the other end abutting against the convex portion. By arranging the disc spring, not only can a good buffering effect be achieved, but also under the reset elastic force of the disc spring, the pull claw 16 can be quickly driven to reset, which is beneficial to improving the cooperation effect between the pull claw 16 and the pull stud 4.

[0041] Optionally, a fitting sleeve 20 for accommodating the elastic element 21 is arranged on the driven turntable 5, and the fitting sleeve 20 communicates with the positioning hole 15. Exemplarily, a threaded connection can be adopted between the fitting sleeve 20 and the driven turntable 5.

Among them, the fitting sleeve 20 can not only play a good protective role for the elastic element 21, but also play a good guiding role for the elastic element 21, which is beneficial to improving the reliability of the elastic element 21 during use.

[0042] During the assembly process, the operator can first install the driven turntable 5 with the pull claw 16 on the taper sleeve 18, then insert the conical surface portion 19 and the fitting sleeve 20 into the taper sleeve 18 in sequence and install them on the driven turntable 5 in sequence, and finally install the connecting member 17 with the elastic element 21 and the tool clamping cylinder 12 again. The operation is simple, which is beneficial to reducing the use and maintenance difficulty of this fixing device.

[0043] Optionally, the jaw assembly includes jaws 11 and a telescopic rod 10. The jaws 11 are rotatably mounted on the equipment rack 9.
