Problems solved by technology

[0002] In the prior art, the rotary motion of the worktable of the vertical lathe and the feed motion of the tool rest are mutually independent transmission mechanisms. Since there is no transmission chain, the transmission ratio between the two cannot be guaranteed.
Since the vertical lathe cannot guarantee the strict transmission ratio between the workpiece rotation and the feed motion of the tool required for thread processing, it cannot process the threads of large workpieces.

Abstract

The invention discloses a speed feedback mechanism for a vertical lathe worktable. A worktable (1) is arranged on a fixedly-arranged main shaft (4) and is driven by a rotary driving mechanism; a rotary coder (5) is arranged on the main shaft (4); and a signal circuit of the rotary coder (5) is connected with an electrical control system of the vertical lathe. By adopting the technical scheme, the mounting and positioning precision of a speed measuring mechanism of the speed feedback mechanism is high, and thus the speed feedback mechanism is convenient for producing and manufacturing; and after the numerical control knife rest vertical lathe is provided with the set of coder mechanism, the function of threading can be achieved.

Description

technical field [0001] The invention belongs to the technical field of metal cutting machine tools, and relates to a transmission mechanism of a workbench of a vertical lathe. More specifically, the invention relates to a speed feedback mechanism of a workbench of a vertical lathe. Background technique [0002] In the prior art, the rotary motion of the worktable of the vertical lathe and the feed motion of the tool post are mutually independent transmission mechanisms, and since there is no transmission chain, the transmission ratio between the two cannot be guaranteed. Since the vertical lathe cannot guarantee the strict transmission ratio between the workpiece rotation and the feed motion of the tool required for thread processing, it cannot process the threads of large workpieces. Contents of the invention [0003] The invention provides a speed feedback mechanism of a vertical lathe workbench, the purpose of which is to realize thread processing on the vertical lathe....
