Problems solved by technology
However, limited by the overall structure of the machine tool, the ratio of the length dimension of the paired positioning racks to the section width and height dimension is about 20:1, which belongs to the slender type of slats. When the tooth surface is cut, the stress is not completely released, and the deformation and bending are serious after loosening, which cannot meet the use requirements

Embodiment Construction
[0016] see Figure 1 to Figure 5 , the processing method of processing and positioning racks in pairs to ensure the same height of the tooth surface, through the design of special paired positioning racks for grinding tires, to ensure that the grinding state and the paired positioning racks when grinding the tooth surfaces of paired positioning racks The use state on the machine tool is consistent, so as to ensure the tooth surface contour of the paired positioning rack and reduce deformation before and after grinding, and at the same time, the tooth surface contour of the paired positioning rack returns to the state during grinding, thus ensuring The equal height of the tooth surfaces at the same position of the paired positioning racks is within 0.005. The paired positioning rack grinding tire 1 is composed of a grinding tool seat 2, a short backing plate 3, a round head set bolt 4, and a T-slot bolt 5, and the left side of the grinding tool seat 2 is threaded A plurality ...

The invention discloses a machining method for machining positioning racks in pairs to guarantee the consistency of a tooth surface, and the machining method is characterized in that a special paired positioning rack grinding mold is designed to guarantee that the grinding state for grinding the tooth surface of the paired positioning racks to be consistent with the application state of the paired positioning racks on a machine tool, the consistency of the tooth surface of the paired positioning racks can be guaranteed, the deformation of the tooth surface of the paired positioning rack before and after the grinding can be reduced, the consistency of the tooth surface of the paired positioning racks can be restored to the state in grinding, and the consistency of the tooth surface on the identical position of the paired positioning racks can be guaranteed to be less than 0.005. By designing the special paired positioning rack grinding mold and the corresponding grinding machining method, mechanical machining is carried out by simulating a working condition of the paired positioning racks, so that the consistency of the tooth surface on the identical position of the paired positioning racks can be further guaranteed. The severe influence of the consistency of the tooth surface on the identical position of the paired positioning racks on the G5 precision of the machine tool and the component machining precision can be thoroughly solved.
Description
technical field [0001] The invention relates to a processing method for processing and positioning racks in pairs to ensure tooth surface contours, and belongs to the technical field of mechanical processing. Background technique [0002] The stereotyped products SVT80~SVT250 single-column vertical lathe and DVT250-DVT630 double-column vertical lathe produced by our factory are supported by the synthetic pair of positioning racks on both sides of the column, and the electrical control positioning pin is supported on the tooth surface of the positioning rack to ensure that the tool holder The crossbeam is in a suitable fixed position during the processing of parts, eliminating the influence of slight changes in the position of the crossbeam on the accuracy of the processed parts. Therefore, the tooth surface contour at the same position of the paired positioning racks has a significant impact on the G5 accuracy of the machine tool and the machining accuracy of the parts. In ...
