Detailed Description
The technical solution of the present invention will be described clearly and completely below with reference to the embodiments of the present invention, and it should be understood that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
With reference to the accompanying drawings 1-3, a general type clamping frock of automobile flywheel drilling, including bottom plate 1, 1 upper surface middle part of bottom plate is equipped with base 2, and 2 middle parts of base run through and are equipped with center pin 4, and 1 middle part of bottom plate corresponds center pin 4 and is equipped with centering shaft 3, and 1 upper portion of bottom plate is equipped with three group's support fixed knot around base 2 and constructs, and the contained angle between three group's support fixed knot constructs is 120, and every group support fixed knot constructs including fixing the cylinder bottom plate 5 at 1 upper surface of bottom plate, and 5 upper portions of cylinder bottom plate are equipped with bracing piece 7 and compress tightly cylinder 8, the top that compresses tightly cylinder 8 rotates and is equipped with clamp plate 9, and bracing piece 7 is located and compresses tightly between cylinder 8 and the base 2. And a supporting pad 6 is arranged between the supporting rod 7 and the cylinder bottom plate 5. The strip-shaped holes 10 are formed in the two sides of the cylinder bottom plate 5, and the fastening pieces are arranged in the strip-shaped holes 10 to connect the cylinder bottom plate 5 to the bottom plate 1.
The utility model discloses adopt the supporting mode of height support flywheel one side such as adjustable three points when concrete implementation, compress tightly the clamping mode of cylinder 8, as shown in fig. 1, the figure position compresses tightly the state for the flywheel on the frock. The center of the flywheel is determined by matching the central shaft 4 with the center hole of the flywheel. The flywheels of different models are different in size, and the diameters, heights and outer diameters of the center holes of the flywheels related to positioning and pressing are arranged in the tooling, and the positions of the center shaft 4, the base 2, the support rod 7 and the cylinder bottom plate 5 corresponding to the center holes are all arranged to be replaceable or adjustable structures so as to adapt to the sizes of different models. The flywheel mounting holes to be processed are generally uniformly distributed in a three-point group manner in the circumferential direction, and the three pressing cylinders 8 are also uniformly distributed in the circumferential direction at three points, as shown in fig. 2, so that the cylinders can avoid the flywheel mounting holes to be pressed, and the positions of drilling holes are not influenced. The pressing cylinder 8 adopts a three-connecting-rod mechanism for pressing, and after the cylinder is released, as shown in figure 3, the cylinder pressing plate 9 can be completely opened, so that the assembly and disassembly of the flywheel are not influenced at all. Secondly, the cylinder compresses tightly can realize quick compressing tightly and unclamp, and efficiency is high.
The tool use adjusting method comprises the following steps: in fig. 1, the supporting pad 6, the supporting rod 7 and the pressing cylinder 8 are all installed on the cylinder bottom plate 5 and can move along with the cylinder bottom plate 5. In fig. 2, the position of the compaction cylinder 8 is adjusted according to the outer diameters of flywheels of different models by the back and forth movement of the cylinder bottom plate 5. The position of the cylinder can be finely adjusted through the strip-shaped holes 10 of the cylinder bottom plate 5, the position of the cylinder can be coarsely adjusted by replacing threaded holes of the bottom plate, and the adjustment of the flywheel with the outer diameter of phi 263-phi 599mm can be realized. The flywheel of different models, centre bore diameter, height also can be inequality, need change the center pin 4 that figure 1 shows, base 2, bracing piece 7 according to the size, wherein bracing piece 7 highly adjusts through changing supporting pad 6, and the height-adjusting compresses tightly with supporting flywheel rear cylinder, and the visual observation clamp plate 9 level can, and three back bracing piece 7 difference in height should not exceed 0.15mm after adjusting. The adjustment of the base 2 is based on the principle that the central shaft 4 is completely matched with the central hole of the flywheel, and the chassis of the central shaft 4 does not interfere with the flywheel.
The present invention and the embodiments thereof have been described above, but the description is not limited thereto, and the embodiment shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. In summary, those skilled in the art should understand that they should not be limited to the embodiments described above, and that they can design the similar structure and embodiments without departing from the spirit of the invention.
