[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Example 1, such as Figure 1-4 As shown, this utility model provides a technical solution: a lifting fixture for improving the efficiency of manual immersion coating, including a lifting platform 1, a vertical pole 2, and a limiting installation block 10. A balancer 3 is installed at the top of the lifting platform 1, and positioning rods 4 are installed at the four corners of the top of the lifting platform 1. A lifting chain 5 is provided at the top of the positioning rods 4. An installation groove 6 is opened inside the lifting platform 1, and a guide rod 7 is provided on the inner wall of the installation groove 6. A moving block 8 is sleeved on the outer wall of the guide rod 7. The limiting installation block 10 is installed at the bottom of the moving block 8, and a cylinder head water jacket core assembly sand core is placed above the limiting installation block 10. The lifting platform 1 has uprights 2 installed on both sides at its bottom. The lifting fixture is suspended above the casting coating pool by the lifting chain 5. The cylinder head water jacket core assembly sand core is placed on the limiting installation block 10 of the lifting platform 1 by the operator. Through the balancer 3 installed above and the buoyancy of the coating pool itself, a dynamic balance is formed with the weight of the overall cylinder head water jacket core assembly sand core and the weight of the lifting fixture. The operator can complete the coating work of the cylinder head water jacket core assembly sand core in the coating pool by lightly touching the sand core. This structure is simple to make, easy to operate, improves the coating quality, reduces the labor intensity of workers, and improves labor productivity.
[0017] Example 2, as Figure 1-6As shown, this utility model provides a technical solution: a lifting fixture for improving the efficiency of manual immersion coating, comprising a movable block 8 with a limiting mechanism 9 for penetrating the interior of a lifting platform 1. The limiting mechanism 9 includes an I-shaped groove 901 and a rotating screw 902. The movable block 8 has an I-shaped groove 901 inside, and the rotating screw 902 is threadedly connected inside the I-shaped groove 901. The bottom end of the rotating screw 902 is fitted with a meshing tooth block 904 via a bearing. A rigid spring 903 is sleeved on the outer wall of the rotating screw 902 and connected to the I-shaped groove 901 and the meshing tooth block 904. The top end of the lifting platform 1 has a sliding groove 905, and the bottom end of the sliding groove 905 is fitted with a limiting tooth block 9 that meshes with the meshing tooth block 904. 06. A limiting tooth block 906 is installed at the bottom of the moving block 8, and the limiting tooth block 906 is adapted to the inside of the slide groove 905. Four sets of limiting installation blocks 10 are installed at the upper lifting platform 1. The limiting installation blocks 10 are made according to the different shapes of the product type. By rotating the rotating screw 902 upward through the I-shaped groove 901, the rotating screw 902 drives the meshing tooth block 904 to not contact the limiting tooth block 906, and the rigid spring 903 is tightened. At this time, the moving block 8 is pushed, so that the slide groove 905 and the limiting installation block 10 move parallel to each other in the slide groove 905 and the guide rod 7, respectively, thereby achieving the function of making support points for different shapes, so as to achieve the ability to switch between different products at any time to use the lifting tool.
[0018] Working principle: First, the operator suspends the lifting fixture above the casting coating tank using the chain 5. The operator then manually places the cylinder head water jacket core assembly sand core onto the limiting mounting block 10 on the lifting platform 1. Through the balancer 3 installed above and the buoyancy of the coating tank itself, a dynamic balance is formed with the weight of the entire cylinder head water jacket core assembly sand core and the lifting fixture. The operator can easily complete the coating work by lightly touching the sand core in the coating tank. This structure is simple to manufacture, easy to operate, improves coating quality, reduces worker labor intensity, and increases labor productivity. (The last sentence appears to be incomplete and possibly refers to a separate point about the lifting platform 1.) Four sets of limit mounting blocks 10 are installed, and the limit mounting blocks 10 are made according to the different shapes of the product types. By rotating the rotating screw 902 upward through the I-shaped groove 901, the rotating screw 902 causes the meshing tooth block 904 to not contact the position of the limit tooth block 906, resulting in the compression of the rigid spring 903. At this time, the position of the moving block 8 is pushed, so that the position of the slide 905 and the limit mounting block 10 moves parallel within the slide 905 and the guide rod 7, respectively, thereby achieving the function of creating support points for different shapes, so as to achieve the ability to switch between different products at any time and use the lifting tool.
[0019] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
