Abstract
The utility model discloses a bench work scribing device for heavy castings. In the device, thread ends of two sliding rods are connected with center screw holes of foundation bases, two transverse carriers are installed on the sliding rods in a one-to-one correspondence mode. Two ends of a transverse rod are respectively inserted in the two transverse carriers. A sliding ring which is tied with a plumb is sleeved on the transverse rod in an empty mode. Movement and fixing of the transverse carriers on the sliding rods are achieved by that fastening screws on the transverse carriers are unscrewed and screwed, and the purpose that the plumbed is moved or positioned is achieved. When the bench work scribing device for the heavy castings is used for scribing the heavy castings, accumulative errors and random errors are eliminated when a traditional scribing device and a scribing method are used for conducting vertical direction precision aligning. Thus, three-dimensional scribing precision of the castings is greatly improved.
