Examples
A processing device for drilling multiple holes on a bearing seat of a processing center has a structure shown in figures 1-3, and can position a part 4 arranged on a processed bearing seat in three directions of an X axis, a Y axis and a Z axis, so that the processing precision and the stability are improved. The device is last including tool bottom plate 3, connects main shaft connection pad 1 and the four-axis connection pad 2 at tool bottom plate 3 both ends, sets up wedge locating piece 5 and the location cylinder bolt 6 at tool bottom plate 3 upper surface, blocks by processing bearing frame part 4, sets up the side clamp plate 8 at tool bottom plate 3 lateral part, fixes on tool bottom plate 3 through clamp bolt 9 and compresses tightly by processing bearing frame part 4.
The used wedge-shaped positioning block 5 not only belongs to a positioning element, but also plays a limiting role and is a core component of the whole set of processing device. The wedge-shaped positioning block 5 can slide on the tool base plate 3 within a certain range, one surface facing the processed bearing seat part 4 is a wedge-shaped inclined surface, and the wedge-shaped positioning block is matched with the design of the inclined surface angle of the wedge-shaped positioning block and used for adapting to bearing seat parts with different opening sizes and propping against an opening, so that the workpiece is prevented from rotating and displacing in a plane formed by an X axis and a Y axis during processing, and the actual processing of the product is influenced. (the product is not hard up, and two hole positions are beaten askew) and wedge locating piece 5 can also be changed according to the size of being processed bearing frame part 4, adjusts the angle of inclination of wedge inclined plane.
The two ends of the positioning cylindrical bolt 6 are turned with threads, the positioning cylindrical bolt is connected to the tool bottom plate 3 through the threads at the bottom end, the middle part is a cylindrical shaft section, and the positioning cylindrical bolt 6 is sleeved with a bearing seat part hole during installation and then locked by the threads sleeved with the upper end of the M12 nut 7.
The side pressing plate 8 and the pressing bolt 9 are used in a matched mode, a threaded hole is formed in the tool bottom plate 3, the pressing bolt 9 is screwed into the threaded hole and used for pressing the side pressing plate 8 to press a workpiece, and the workpiece is prevented from vibrating and deviating.
The spring 10, the telescopic bolt 11 and the limit stop 12 are matched for use. The spring is sleeved in the telescopic bolt to penetrate through the wedge-shaped positioning block, the bolt is screwed on the limit stop, the wedge-shaped positioning block can horizontally move on the tool bottom plate in a small range by screwing and loosening the bolt, and an operator can drive the wedge-shaped positioning block to tightly push the workpiece by screwing the bolt when installing a bearing seat workpiece. (work can be pulled inside and outside to check whether the work is tight)
One side of tailstock connection pad 1 and four-axis connection pad 2 towards frock bottom plate 3 is equipped with the fluting, and frock bottom plate 3 inserts in the fluting. The other side surfaces of the tailstock connecting disc 1 and the four-axis connecting disc 2 are connected to the main shaft and the four-axis through bolts. The tool bottom plate 3 connected in this way can realize free rotation processing on the processing center.
The bearing seat part 4 to be machined involves various hole machining such as a plurality of through holes, four threaded holes, 4 pin holes (different in pairs), a nameplate hole and the like, so the machining is most suitable on a machining center. All the holes can be processed at one time by the processing center, and two counter bores on the back can be drilled through four-axis rotation (a reserved hole is drilled on the back of the tool bottom plate, and the counter bores are drilled during the process of rotating the tool in the aspect).
I think that two earholes are processed and finished on the processing device when designing the secondary tool, utilize four-axis to respectively rotate 90 degrees in the positive and negative directions, will two
The ear hole is directly processed. In the initial design stage, the diameter of the lug hole is considered to be large, and the load requirement on a machine tool is high, so that the process route is to drill a bottom hole on a drilling machine and then machine a central boring hole. In the process of sample processing, the processing parameters are adjusted (the rotating speed is slowed down when the lug holes are punched), smooth processing under the condition that the specified load is not exceeded can be met, so that the manual cost and the equipment cost are saved by combining processes in the subsequent processing process, and the vacated machine tool can be used for processing other products.
The positioning cylindrical bolt 6 and the wedge-shaped positioning block 5 are two important positioning elements of the processing device. The cylindrical bolt is positioned to roughly position the workpiece, and the wedge-shaped positioning block 5 completely positions the workpiece (the positioning element has the requirement of symmetry degree due to the two lug holes, so that the workpiece can be automatically aligned to meet the requirement of form and position tolerance of the symmetry degree 2). After the positioning is finished, the workpiece is completely pressed by a lateral pressing plate and a nut M12 with a shoulder (better strength), and four-axis rotating processing is realized!
