The working principle is as follows:
the adjustable tightening hook 2 of the decomposing device is adjusted to be slightly larger than the diameter of a product part, and then the product part is arranged in a hole of the tightening screw sleeve 1 of the decomposing device. The adjustable tightening hook 2 can be formed by a sleeve which is composed of a conical surface outside, a hole in the center, a sharp edge 21 protruding from the large end of the conical surface into the hole, and a semicircular arc at the small end of the conical surface, and the sleeve is uniformly divided along the radius direction to form the adjustable tightening hook. The adjustable tightening hook 2 extends the flat 22 into the assembly notch 14 on the hook 13 in the tightening screw sleeve 1 and is hung on the hook 13 through the pin 24 in the pin hole 23 on the flat 22, so that the adjustable tightening hook 2 is hung on the hook 13 and is connected with the tightening screw sleeve 1. And the adjustable tightening hook 2 can be conveniently used for exchanging thin-wall part products with different sizes or matched models.
In the operation process, the handle 12 is held by hand, and the wrench is aligned to one end of the tightening nut 5, the outer surface of which is a hexagonal prism, so as to rotate the tightening nut 5, drive the conical surface pressing sleeve 6 to move towards the direction of the adjustable tightening hook 2, and utilize the conical surface in the conical surface pressing sleeve 6 to tightly press the conical surface outer wall of the adjustable tightening hook 2. Wherein because the screw thread fit between tightening nut 5 and the tightening screw sleeve 1 realizes that it moves along the central line extending direction of tightening screw sleeve 1, then can drive conical surface pressure sleeve 6 to the adjustable tightening hook 2 direction of joining in marriage and move. Wherein the conical surface pressing sleeve 6 is connected with the tightening nut 5 through a connecting structure. In the connecting structure, a set screw 8 penetrates through a threaded hole which is avoided by the conical surface pressing sleeve 6 and is pushed into the annular groove 7, so that the conical surface pressing sleeve 6 is fixed on the tightening nut 5 and can move along with the tightening nut 5.
When the conical surface pressing sleeve 6 presses the adjustable tightening hook 2, the adjustable tightening hook 2 rotates inwards around the pin 24 in the pin hole 23, when the protruding sharp edge 21 of the adjustable tightening hook 2 is approximately consistent with the diameter of a product part, the protruding sharp edge 21 of the adjustable tightening hook 2 is aligned with a gap between the two parts of the product, the tightening nut 5 continues to rotate, the conical surface pressing sleeve 6 is driven to continue to shrink the adjustable tightening hook 2, and the protruding sharp edge 21 of the adjustable tightening hook 2 is embedded into the gap between the two parts of the product.
Then, the handle 12 is held by a hand, a wrench is used for aligning one end of the ejection screw 3, which is a hexagonal prism, and rotating the ejection screw 3, meanwhile, the end where the stud of the ejection screw 3 is located is in threaded fit with the internal threaded hole in the central step hole of the tightening screw sleeve 1 and extends into the tightening screw sleeve 1, so that the ejection screw 3 rotates to move along the extension direction of the center line of the tightening screw sleeve 1, the ejection screw 3 drives the pressing block 4 to move towards the product part, the pressing block 4 compresses the product part, the ejection screw 3 is continuously rotated, and the product thin-wall sleeve is taken out of the product. The pressing block 4 passes through the conical hole and the round hole of the pressing block 4 through the connecting screw 41 and is screwed into the connecting threaded hole 31 to be connected with the ejection screw 3, and the pressing block 4 can rotate relative to the ejection screw 3 because the countersunk head of the connecting screw 41 is in the conical hole of the pressing block 4.
After the thin-wall part is removed, the tightening nut 5 is rotated by a wrench to move in the opposite direction of the adjustable tightening hook 2, the adjustable tightening hook 2 is loosened by driving the conical surface pressing sleeve 6, and the three adjustable tightening hooks 2 are opened to be larger than the diameter of the product part, so that the product thin-wall part can be taken out.
Implementation example:
the adjustable tightening hook 2 of the decomposition device is adjusted to be slightly larger than the diameter of a product part, and the product part with the outer diameter of phi 35mm is arranged in a phi 37mm (the maximum detachable product outer diameter phi 37mm) hole of the tightening screw sleeve 1 of the decomposition device. Handle 12 is held with the hand, tighten up nut 5 with the spanner rotation, make it drive the conical surface and press cover 6 to the adjustable 2 directions of joining in marriage and tighten up the hook and move, when the conical surface is pressed and is compressed tightly adjustable and join in marriage and tighten up hook 2, adjustable and join in marriage and tighten up hook 2 will be around pin 24 inside rotation, when the 30 degrees angle point limit that can join in marriage and tighten up hook 2 outstanding is close unanimous with the product part diameter, will join in marriage 30 degrees angle point limits that tighten up hook 2 is outstanding and aim at 45 degrees gaps between two parts of product, continue rotatory tighten up nut 5, drive conical surface and press cover 6 and continue to shrink adjustable and join in marriage and tighten up hook 2, make adjustable 30 degrees angle point limits that tighten up hook 2 is outstanding imbed in the gap between two parts. The handle 12 is held by a hand, the ejection screw 3 is rotated by a wrench, the pressing block 4 and the connecting screw 41 are driven to move towards the product part, the pressing block 4 is enabled to press the product part, the ejection screw 3 is rotated continuously, and the product thin-wall sleeve is taken out from the product. The tightening nut 5 is rotated by a wrench to move towards the opposite direction of the product part, and the adjustable tightening hooks 2 are loosened by driving the conical surface pressing sleeve 6 to move together, and the three adjustable tightening hooks 2 are opened to be larger than phi 35mm, so that the product thin-wall part can be taken out.
It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments.
