Problems solved by technology
[0002] With the development of industry, various large-scale and heavy-duty machine tool industries are developing rapidly. Due to the large span of the guide rail beam and the heavy weight of the slide seat assembly, errors in the machining accuracy of the machine tool are now compensated by finite element analysis or stress calculation. It is time-consuming and labor-intensive to carry out the simulation test for verification, which is suitable for mass production. However, how to solve the processing of heavy-duty long guide rail beam guide rail surface processing for most enterprises, most of which are single-piece and small-batch production is an urgent problem to be solved at present.

Embodiment Construction
[0016] see Figure 1 to Figure 5 , Heavy-duty long guide rail beam guide rail surface processing technology, 1. On the semi-finished guide rail beam 1, find out the support points 11 of the support lines on both sides according to the actual support column positions. 2. Draw the measuring line 12 evenly between the supporting points 11 on both sides, and the distance between the measuring lines 12 is between 300-500mm. 3. The support points 11 on both sides set up the guide rail beam 1 on the machine tool table 14 through the three support seats 2 and adjust the level of the upper plane. 4. Put the actual object of the sliding seat assembly of the equipment or the weight 4 of the same quality in the bearing plate 3 . 5. Place the load-bearing plate 3 together with the weight 4 on each measuring line 12 above the guide rail beam 1 in sequence. 6. Put the dial indicator 7 on the measuring line 12 below the guide rail beam 1 in turn to perform metering measurement, and make a r...

The invention discloses a machining process for the guide rail surface of a heavy long guide rail beam. The machining process comprises the following steps: directly loading a semi-finished guide rail cross beam on a machine tool workbench point by point according to a measuring line and the actual weight of a sliding seat assembly, and carrying out deformation measurement to obtain a downward deformation curve of each measuring point of the actual guide rail cross beam; pressurizing each measuring point of the guide rail cross beam by using a pressing plate according to the actual deformation curve to obtain a downward deformation curve which is the same as each actual measuring point of the guide rail cross beam again, and then directly performing finish machining on the guide rail surface of the guide rail cross beam on the machine tool; after machining and unloading, taking the upper plane of the guide rail beam as a reverse curved surface of an actual deformation curved surface obtained through loading measurement, enabling the guide rail beam to be always in a straight state when moving after being provided with a sliding seat assembly, and meeting the linear machining requirement of a machine tool. The machining process is suitable for single-piece small-batch production, simple, high in practicability, accurate, reliable and worthy of application and popularization.

technical field [0001] The invention relates to a processing technology, in particular to a processing technology for a heavy-duty long guide rail beam guide rail surface, and belongs to the technical field of the machine tool industry. Background technique [0002] With the development of industry, various large-scale and heavy-duty machine tool industries are developing rapidly. Due to the large span of the guide rail beam and the heavy weight of the slide seat assembly, errors in the machining accuracy of the machine tool are now compensated by finite element analysis or stress calculation. It is time-consuming and labor-intensive to process, and simulation tests are required for verification. It is suitable for mass production, but how to solve the processing of heavy-duty long guide rails and beam guide rail surfaces that most enterprises produce in single-piece and small batches is an urgent problem to be solved at present.
