Description

Technical Field

[0001] This utility model relates to the field of motor end ring production technology, and more specifically, to a raw material sawing mechanism for end ring processing. Background Technology

[0002] The raw material for motor end rings is generally cylindrical copper material (copper rod, bar). During processing, the copper material needs to be cut into individual round pieces, and then the center of the round pieces is punched and enlarged before being processed into the shape of an end ring by a CNC lathe.

[0003] Utility model patent application number CN202322243121.6 discloses a raw material sawing mechanism for end ring processing, including a worktable. A first motor is fixedly installed at one end of the worktable, and a first transmission rod is splinedly connected to the output end of the first motor. This raw material sawing mechanism for end ring processing utilizes a feeding plate, a U-shaped plate, a threaded knob rod, a clamping plate, a mounting groove, a spring, a slide rod, a clamping half-ring, and the slide rod in a coordinated arrangement. In use, a copper tube is placed on the feeding plate, and the height of the clamping plate is adjusted by rotating the threaded knob rod. This causes the clamping half-ring to abut against the surface of the copper tube, thus fixing copper tubes of different sizes and effectively improving production efficiency. Through the coordinated arrangement of a sleeve, an extension rod, and a baffle, the extension rod is pulled out from inside the sleeve to a suitable length during use, and then a fixing bolt is screwed into the sleeve and the extension rod for fixation, thereby adjusting the sawing length of the end ring.

[0004] The patented method involves rotating a threaded knob to adjust the height of the clamping plate, which then abuts the clamping half-ring against the surface of the copper tube, thereby fixing copper tubes of different sizes. Since the blade may not be able to complete the cut in one go when cutting metal bars with a large diameter, it is necessary to re-fix the metal bar after rotating it. This requires not only ensuring the stability of the metal bar, but also carefully readjusting its position to ensure it is precisely below the blade. Otherwise, the subsequent cutting operation cannot be guaranteed to proceed smoothly, resulting in cutting failure and wasting metal bars.

[0005] Therefore, we have made improvements to this by proposing a raw material sawing mechanism with end ring processing. Utility Model Content

[0006] The purpose of this invention is to address the issue that when cutting metal bars with large diameters, the blade may fail to complete the cut in one go. After rotating the metal bar, it is necessary to re-fix it.
