Bed splicing positioning key of machining center

Abstract

The invention relates to a bed splicing positioning key of a machining center, comprising a first bed and a second bed. The bed splicing positioning key is characterized in that a T-shaped key, a first slope key and a second slope key are arranged in a splicing key groove of the first bed and the second bed. A slope is respectively machined at upper and lower surfaces of a convex part of the T-shaped key. Slopes are respectively machined at the contact surfaces between the first slope key and the T-shaped key, as well as between the second slope key and the T-shaped key. As the slopes of 1: 100 are both machined at the junctions of the T-shaped key and the slope keys, the two slope keys do not need to be repaired after the T-shaped key is installed in place, and the slope keys can be directly arranged in gap between the T-shaped key and the beds, thereby achieving the purpose of positioning between the two spliced beds. Compared with the ordinary flat key, the bed splicing positioning key reduces repair surfaces and can overcome the shortcomings that the ordinary flat key needs to be sectioned for repair under the situation and the operation difficulty is great. The bed splicing positioning key can achieve the design requirements of positioning of the ordinary flat key, has simple repair, convenient installation and improves the work efficiency.

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] Before the present invention is made, in existing solutions, genera...

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.
