Description
Technical Field
[0001] The utility model relates to the technical field of turning machines, in particular to an external cylindrical turning machine for mechanical processing. Background Art
[0002] Turning is the main method for rough machining and semi-finishing of the outer cylindrical surfaces of various materials (steel, cast iron, non-ferrous metals, non-metals, etc.), and is also the final finishing method for various materials that are not suitable for grinding (non-ferrous metals such as copper and aluminum). However, hardened workpieces are not suitable for turning and are usually ground. During the production process, cylindrical workpieces are turned by external turning machines to improve their own outer arc surface processing accuracy. When using external turning machines for some mechanical processing, the staff first clamps and fixes the cylindrical workpiece with a three-jaw chuck, and then makes the cylindrical workpiece rotate at high speed through the driving element, and then rotates the hand wheel through the lead screw thread connection to move the turning tool of the external turning machine longitudinally and horizontally, respectively, so that the turning tool can turn the outer circle of the high-speed rotating cylindrical workpiece. However, a large amount of turning residues will be generated during the turning process of the outer circle of the cylindrical workpiece. These residues remain on the turning machine worktable. Long-term accumulation will hinder the turning accuracy of the outer circle of the cylindrical workpiece of the turning machine, which needs to be improved. Utility Model Content

[0023] The working principle of an external cylindrical turning machine for mechanical processing provided by the utility model is as follows: when turning the external cylindrical workpiece of a cylindrical workpiece, the cylindrical workpiece is first fixed by a three-jaw chuck 4, and then the single-chip computer 2 starts the motor 1 5 so that its output shaft indirectly drives the cylindrical workpiece to rotate around its own axis through the rotating shaft 1, and then the single-chip computer 2 starts the motor 3 11 in the middle so that its output shaft drives the corresponding stud 2 10 to rotate, and the stud 2 10 is connected by a thread so that the tool holder 8 moves longitudinally along the slide groove 3 toward the cylindrical workpiece, thereby longitudinally turning the turning tool 9 of the turning machine. The cylindrical workpiece is then rotated and the outer circle of the cylindrical workpiece is turned by the turning tool. Then, the single-chip computer 2 starts the motor 3 11 on the right side so that its output shaft drives the corresponding stud 2 10 to rotate, and the turning frame 7 drives the turning tool 9 of the device along the slide groove 2 to move the outer circle of the cylindrical workpiece horizontally through the threaded connection. When the device has completed the turning of the outer circle of the cylindrical workpiece, the single-chip computer 2 starts the motor 2 69 so that its output shaft drives the stud 1 68 to rotate.

Then, as the moving seat 61 continues to move, the meshing connection between the gear three 662 and the rack plate 661 causes the rearmost rotating shaft 2 62 to rotate, and the rotating shaft 2 62 is meshed with the gear two 65 and the gear one 64 to cause the brush seat 63 to rotate around its own axis. The brush on its lower side rotates in contact with the outer cylindrical turning residues of the bottom cylindrical workpiece of the turning table 1, thereby dynamically cleaning it to avoid the adhesion of turning residues and improve the turning residue cleaning effect of the device on the outer cylindrical turning machine of the cylindrical workpiece. Then, it moves through the moving seat 61, and with the help of two auxiliary scrapers 672, the outer cylindrical turning residues of the cylindrical workpiece are cleaned into the corresponding slag discharge groove 12. It is easy to use, and the output shaft of the motor 2 69 is controlled by the single-chip microcomputer 2 to rotate forward and reverse, so as to control the left or right movement of the cylindrical workpiece outer cylindrical turning residue cleaning part of the device.
