Problems solved by technology
And we know that the bed segments cannot be shortened indefinitely, otherwise, the strength may be reduced and the processing performance of machine tool products may be affected
Moreover, even if technically allowed, the more segments, the less economical to process
Therefore, the above-mentioned process method has many deficiencies such as many sections and high processing cost.

Embodiment Construction
[0016] The main processing machine takes the gantry type processing center XH2425 / 12 as an example. The stroke of the table is 12 meters, and the total length of the machined bed is 30 meters.
[0017] The processed bed with a total length of 30 meters is divided into three sections, each section is 10 meters.
[0018] according to figure 1 The shape of the machined bed shown in the figure first designs and processes a tool setting template 1. The cross-sectional shape and material of the tool setting model are completely consistent with each processing surface of the machined bed, and its thickness is 80 mm. The public benchmark of the tool setting template 1 is fixedly installed on the tool setting template support 2 at one end of the worktable of the processing machine, and the tool setting sample support 2 is integrally installed on the working table 6 of the processing machine, and the sample support 2 is the tooling in the process of processing; Then fix the segmented f...

The invention discloses a processing method of a multi-segment extension lathe bed, comprising the following steps of: firstly designing and processing a tool setting sample plate with the thickness of 60-100 millimeters according to the section shape and the material quality of a lathe bed to be processed, fixedly installing the tool setting sample plate on a tool setting sample plate support at one end of a working table of a processing master, and then fixing a segmented first-segment lathe bed on the working table; and then processing the lath beds according to the following steps of: (1) roughly processing the first-segment lathe bed without using the tool setting sample plate; (2) simultaneously carrying out semi-finished processing on the first-segment lathe bed and the tool setting sample plate and then sequentially installing other segments of lathe beds to carry out contour processing based on the tool setting of the tool setting sample plate; (3) sequentially carrying out contour fine processing on each-segment lathe bed according to the step (2); and (4) processing both end surfaces of each-segment lathe bed to make the lathe beds meet extension requirements. The method can be used for processing the segmented lathe bed slightly shorter than the total stroke length of the processing master, thereby realizing that small machine tool with a short stroke carries out segmented contour processing on an overlength lathe bed.
Description
technical field [0001] The invention relates to a processing method for a machine bed, in particular to a processing method for a multi-segment extended bed. Background technique [0002] In recent years, with the development of social economy and the advancement of equipment manufacturing technology, the demand for large, heavy and even super-heavy high-end machine tools has been increasing. In the research and development of large-scale high-end machine tools, how to process and manufacture large-scale parts has become an important technology. problem, specifically how to use existing smaller machine tools to machine large-format parts that exceed their maximum travel. [0003] Segmental processing means that the ultra-long parts to be processed are divided into multiple segments, and then they are connected as a whole after the processing of each segment is completed. This segmental processing method is currently a technology commonly used by machine tool manufacturers at...
