1、 Is Dalian single column double lift vertical car also a kind of vertical car

Vertical lathes can generally be divided into single column and double column. Small vertical lathes are generally made into single column type, and large vertical lathes are made into double column type. The main feature of vertical lathe structure is that its spindle is in a vertical position. The main characteristics of vertical lathe are: the workbench is in the horizontal plane, and the installation and adjustment of workpieces are more convenient. The worktable is supported by guide rail, with good rigidity and stable cutting. There are several tool holders, and the tool can be changed quickly. The machining accuracy of the vertical lathe can reach it9-it8, and the surface roughness Ra can reach 3.2-1.6um The main parameter of vertical lathe is the maximum turning diameter D.

2、 Precautions for vertical car

1. The vertical lathe is mainly used to process large and heavy workpieces with large diameter and short length and workpieces that are not easy to be clamped on the horizontal lathe. When the rotation diameter is met, the workpieces that are too heavy are not easy to be clamped on the sleeper. Due to their own weight, it has an impact on the machining accuracy. The vertical lathe can solve the above problems.

2. Before the vertical car is put into use, its control handle shall be flexible. When pulling the control handle to the "start" position, the rocker arm pressing the friction plate shall reach the self-locking position to ensure reliable positioning; The workbench shall be equipped with a locating plate to prevent the four claw seat from withdrawing.

3. When machining eccentric workpieces, counterweight iron must be added to keep the worktable balanced. The counterweight iron must be firmly clamped to prevent injury from being thrown out; The friction clutch in the fast travel mechanism must be intact and can play a protective role when the load is too large. The safety pin in the safety coupler in the feed box must meet the design requirements to prevent accidents caused by overload.

4. The vertical car shall be equipped with a limit device to prevent the cross beam and tool holder from exceeding the travel when moving; The operating platform shall be equipped with rail and bottom guard. 1.8 all operating hand wheels shall be equipped with positioning devices and obvious gear labels. The bolts and nuts for pressing the hand wheel shall be complete, intact and fastened; The triangular tape and the coupling between the main motor and the gearbox shall be provided with a protective cover; The workbench shall be provided with a fence to prevent injury caused by the rotation of the workbench, and a chip baffle shall be set around it.

5. During the vertical turning operation, the tools and measuring tools shall not be placed on the cross beam tool holder; It is not allowed to remove iron filings directly by hand, but should be cleaned with special tools; When loading and unloading workpieces and tools, closely cooperate with the driver and hooker; The workpiece and cutting tool shall be fastened. The jack, inclined base plate and cushion block used shall be fixed and checked frequently to prevent loosening; Before the workpiece is clamped, it can only be inched to correct the workpiece. Pay attention to keep a certain distance between the human body and the rotating body. It is strictly forbidden to stand on the rotating workbench to adjust the machine tool and operation buttons. Non operators are not allowed to approach the machine tool.
