Locator key for splicing machine tool bodies in processing center

Abstract

The invention relates to a key for splicing and positioning a lathe bed in a machining center, which comprises a first lathe bed and a second lathe bed, and is characterized in that a T-shaped key, afirst flat key and a second flat key are arranged in spliced key grooves of the first lathe bed and the second lathe bed respectively. The T-shaped key, the first flat key and the second flat key arearranged in the spliced key grooves of the first lathe bed and the second lathe bed respectively; and the T-shaped key is arranged in the first lathe bed, and the first flat key and the second flat key are arranged between the T-shaped key and the second lathe bed respectively. A clearance is reserved between a protrusion part of the T-shaped key and the second lathe bed. The key for splicing andpositioning the lathe bed has a simple and reasonable structure, reduces overhauling faces compared with the prior flat key, and can overcome the defect that the prior flat key needs to be overhauledby sections under the condition, thereby causing difficult operation; and the key can reach the design requirements of the prior flat key for positioning, has the advantages of simple overhauling, convenient installation, and labor cost conservation.

Description

technical field [0001] The invention relates to a splicing positioning key for a bed of a machining center. Specifically, it is suitable for use when large-scale mobile machining centers such as gantry milling need to be spliced ​​with multiple sections of bed, and belongs to the technical field of mechanical structures. Background technique [0002] With the rapid development of my country's machinery industry, especially the development of heavy industry, there is an increasing demand for large-scale metal processing equipment such as CNC gantry milling; at the same time, higher requirements are put forward for the technical parameters of the equipment. For large-scale equipment such as CNC gantry milling, the long stroke must be completed by splicing the bed. After the bed is spliced, it is not only necessary to connect with bolts, but also to install keys at the joint of the bed for positioning. [0003] In the prior art, it is generally used to process the keyway at the...

AI Technical Summary

Problems solved by technology

However, due to factors such as machine bed processing and splicing, it is not guaranteed that the keyways on the two bed sections match according to the theoretical requirements, and the positioning flat key designed according to the theoretical situation requires different repair allowances for the keys in the two bed sections. into a stepped shape

The height difference of the keyway on different sections of the bed increases the difficulty in the key repair process and increases the number of repair surfaces, resulting in low work efficiency.
