Description

Technical Field

[0001] The utility model relates to the technical field of machine tool processing, in particular to a machine tool for processing a vehicle bearing seat. Background Art

[0002] In the field of processing technology, it involves the processing and manufacturing of bearing seats specifically used in industries such as petroleum, nuclear energy, pipelines, valves, etc.

[0003] After searching, it was found that the announcement number is CN212443269U, and the name is a machine tool for turning bearing seats. The application proposes that for bearing seats, the size and centering accuracy of the inner hole are the key to quality. The traditional processing method is to turn directly on a lathe, which requires alignment of each piece, has a slow processing speed, and is difficult to ensure accuracy. Through the overall design, compared with the prior art, the block is first fixed to the base with a first bolt and a locating pin, and then the block is installed in the four-jaw chuck, and then the workpiece is loaded, and the workpiece is pressed with a pressure plate, a latch, and a second bolt. The four-jaw chuck drives the base to rotate along the X direction, thereby driving the workpiece to rotate, and the tool moves along the X axis and the Z axis to complete the turning process. After the processing is completed, only the pressure plate needs to be loosened, the workpiece that has been added is taken out, and the workpiece to be processed is loaded, and the pressure plate is fixed to carry out the processing. The clamping is convenient, and no alignment is required, which reduces the operator's The skill requirements of the workers are improved, the production efficiency is improved, the human error is eliminated, the processing accuracy is effectively improved, and the stability of product quality is significantly improved. At the same time, by setting two groups of second bolts, compared with the prior art, the workpiece is placed on the base, and then the pressure plate is placed by means of a snap fit, and four groups of pins are inserted from above, and two groups of second bolts are inserted from the side surface of the base, and each group of second bolts passes through the two groups of pins. After tightening the second bolts, the locking effect of the two groups of second bolts is used to quickly fix the pressure plate, avoiding the use of multiple groups of locking bolts for fixing, and providing higher operational convenience. However, this application uses multiple groups of pressure plates and pin parts during the initial adjustment, and uses multiple groups of bolts for fixing, which is more troublesome. At the same time, it is difficult to perform limit adjustment according to the contour of the bearing seat, and the fit with the edge contour of the bearing seat is low, and the anti-rotation limit effect is not good. Further improvements can be made.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

Figure 1-4 As shown, according to the embodiment of the utility model, the machine tool for processing the vehicle bearing seat includes a gantry machine tool body 1 and a chuck 2. The chuck 2 is installed inside the gantry machine tool body 1, and the top surface of the chuck 2 is fixedly clamped to hold the mounting seat 3, and the mounting seat 3 is fixedly connected with an inner plate 12. The inner plate 12 and the top surface of the mounting seat 3 are respectively penetrated with an inner hole 13 and a top hole 11. The inner hole 13 is located directly below the top hole 11, and a limiting rod 6 is inserted and inserted into the top hole 11, and the limiting rod 6 extends into the inner hole 13. A cork pad 7 is fixedly connected between the bottom surface of the inner plate 12 and the inner bottom surface of the mounting seat 3 to facilitate the limiting rod 6 to penetrate and fix. At the same time, the cork pad 7 has a certain strength. When the limiting rod 6 is not under pressure, the limiting rod 6 itself is not enough to be inserted into the cork pad 7. The two ends of the top surface of the mounting seat 3 are rotatably connected with side frames 4 through second rotating connecting seats 10, and one end of the side frame 4 is penetrated by a threaded connection It is connected to a handle bolt 5, and the other end of the handle bolt 5 is rotatably connected to a pressure plate 9 through a first rotating connecting seat 8. When installing the vehicle bearing seat tooling, the vehicle bearing seat tooling can be placed on the top surface of the limit rod 6. After adjusting the position, the bearing seat tooling is pressed downward, and the bearing seat tooling can squeeze the limit rod 6 located on the bottom surface of the bearing seat tooling. The limit rod 6 of this part can be inserted into the cork pad 7 to form a sinking, and the sunken part forms the contour of the bearing seat tooling. During the later installation, it is only necessary to put the vehicle bearing seat into the contour to quickly position it, eliminating the trouble of frequent positioning. The limit rod 6 sinks according to the contour of the vehicle bearing seat, and the limit rod 6 at the edge of the contour fits perfectly with the edge of the vehicle bearing seat, which has a higher limiting effect on the side of the vehicle bearing seat, avoiding the rotation of the vehicle bearing seat during processing, and has a good limiting effect, eliminating the trouble of bolt fixing. It is convenient and quick to use, and improves work efficiency.

[0031] In one embodiment, a plurality of limiting rods 6 are evenly and densely distributed, and the distribution area of ​​the limiting rods 6 is larger than the maximum projection area of ​​the vehicle bearing seat, so as to facilitate the placement and installation of the vehicle bearing seat.

[0032] In one embodiment, the spacing between the limiting rods 6 is no greater than 1 mm, and the limiting rods 6 are rectangular metal rods to prevent the limiting rods 6 from rotating.

[0033] In one embodiment, a tip 14 is provided on the bottom surface of the limiting rod 6 to facilitate penetration into the cork pad 7, and the projection size of the limiting rod 6 is the same as the size of the top hole 11 to avoid the entry of debris due to excessive gap.

[0034] In one embodiment, the height of the limiting rod 6 is greater than the thickness of the cork pad 7, and the vertical projection area of ​​the cork pad 7 is greater than the distribution area of ​​the limiting rod 6. After the bottom tip 14 of the limiting rod 6 abuts against the inner bottom surface of the mounting seat 3, the upper limiting rod 6 is still located above the top hole 11, and the top hole 11 and the inner hole 13 limit the limiting rod 6.

After adjusting the position, press the bearing seat tooling downward, and the bearing seat tooling can squeeze the limit rod 6 located on the bottom surface of the bearing seat tooling. The limit rod 6 of this part can be inserted into the cork pad 7 to form a sinking, and the sunken part forms the contour of the bearing seat tooling. During the later installation, you only need to put the vehicle bearing seat into the contour to quickly position it, eliminating the trouble of frequent positioning. The limit rod 6 sinks according to the contour of the vehicle bearing seat, and the limit rod 6 at the edge of the contour perfectly fits and abuts against the edge of the vehicle bearing seat. The side limiting effect of the vehicle bearing seat is higher, which prevents the vehicle bearing seat from rotating during processing. The limiting effect is good, which saves the trouble of bolt fixing, is convenient and quick to use, and improves work efficiency. At the same time, the side frame 4 can rotate along the second rotating connecting seat 10, and the staff can rotate the side frame 4 to make the pressure plate 9 located above the surface of the vehicle bearing seat that does not participate in the processing. Then, turning the handle bolt 5 can drive the pressure plate 9 to move downward, drive the pressure plate 9 to press against the vehicle bearing seat, and avoid up and down movement during processing. The fixing stability is high, and the fixing is more convenient and quick, which further improves the convenience of use and work efficiency.
