Description

Technical Field

[0001] The utility model relates to the technical field of remanufacturing tooling, and more specifically, to an engine remanufacturing tooling. Background Technique

[0002] In order to avoid waste of resources, old machines will be recycled, reformed and reused. When recycling, reforming and reusing, each component needs to be assembled with the cylinder block. The existing assembly method is to place the cylinder block on the operating table and then directly assemble it. Since the cylinder block is heavy by itself and different angles are involved during assembly, the operator has to manually rotate and adjust the position of the cylinder block. On the one hand, the labor intensity of the operator is relatively large and the assembly efficiency is also low; on the other hand, continuously rotating and adjusting on the operating table will also cause damage to the cylinder block. In the existing patent, an engine remanufacturing tooling with the patent authorization number CN 215148654 U reduces the labor intensity of the operator and improves the assembly efficiency on the one hand; on the other hand, it avoids damage to the cylinder block.

[0003] However, in the patent with the authorization number CN 215148654 U, two positioning units placed in the storage tray are taken out, and then one is placed on each side of the cylinder block to be fixed. The fixing plate on the positioning unit is attached to the cylinder block and fixed to the cylinder block through several screws respectively passing through the positioning holes. The operation of fixing the cylinder block with bolts is very cumbersome. It is necessary to use multiple bolts to fix the cylinder block one by one, and the operation is relatively inconvenient. Therefore, we propose an engine remanufacturing tooling to solve the above existing problems. Content of the Utility Model

[0037] It should be noted that, by placing the cylinder body of the scrapped engine on the upper surface of the rotating seat 2, and then rotating the double-headed screw 4 according to the size of the engine, the spacing between the pressure plates 8 can be adjusted by sliding the movable seat 5 in cooperation with the guide groove 3, so that the end of the pressure plate 8 can correspond to the edge of the cylinder body, and then the double-acting cylinder 9 is externally connected to a pneumatic control device, and the pneumatic control device is used to control the extension and retraction of the movable end of the double-acting cylinder 9. The movable end of the double-acting cylinder 9 is extended, and the connecting shaft 10 is rotated in cooperation with the movable end of the double-acting cylinder 9. At the same time, the pressure plate 8 is rotated in cooperation with the open groove 7 opened at the top of the support plate 6, so that the end of the pressure plate 8 is pressed down and abuts against the edge of the cylinder body, thereby quickly fixing the cylinder body, and the operation is very convenient.

[0038] like Figure 2 As shown, one end of the double-headed screw 4 passes through the guide groove 3 and extends to the outside of the rotating seat 2, and there is no thread arrangement at the place where the double-headed screw 4 passes through the rotating seat 2, and a hand wheel 11 is installed at the through end of the double-headed screw 4;

[0039] It should be noted that the hand wheel 11 is provided to facilitate driving the double-headed screw 4 to rotate.

Then, it moves through the cooperation of the guide post 14 and the guide hole 16, and the guide post 14 is limited by the limit block 15, and the accessories are moved to the assembly position of the cylinder block, which is convenient for the assembly of the accessories, thus realizing the remanufacture of the waste engine.

[0047] During use: Place the cylinder block of the waste engine on the upper surface of the rotating seat 2, and then rotate the double-headed screw 4 according to the size of the engine. The distance between the pressure plates 8 can be adjusted by sliding the movable seat 5 in cooperation with the guide groove 3, so that the end of the pressure plate 8 can correspond to the edge of the cylinder block. Then, the double-acting cylinder 9 is externally connected to a pneumatic control device, and the pneumatic control device is used to control the expansion and contraction of the movable end of the double-acting cylinder 9. When the movable end of the double-acting cylinder 9 extends, the connecting shaft rod 10 rotates in cooperation with the movable end of the double-acting cylinder 9, and at the same time, the pressure plate 8 rotates through the opening groove 7 opened at the top of the support plate 6, so that the end of the pressure plate 8 presses down and abuts against the edge of the cylinder block, thereby quickly fixing the cylinder block.
