Technical Field

[0001] This utility model relates to the field of piston tooling, specifically a piston pressing tooling. Background Technology

[0002] The piston is a reciprocating component in the cylinder block of a car engine. The basic structure of the piston can be divided into the top, head, and skirt. The piston top is the main part that makes up the combustion chamber. Its shape is related to the type of combustion chamber selected. Gasoline engines mostly use flat-top pistons, which have the advantage of a small heat absorption area. The piston top of diesel engines often has various kinds of pits. Their specific shape, position, and size must be adapted to the requirements of mixture formation and combustion in diesel engines.

[0003] In existing technology, pistons are mainly installed in piston cylinders. To help employees install pistons more easily, tooling is usually used to improve installation efficiency. However, the diameters of various pistons are different, making it difficult for tooling to install pistons of different sizes, thus reducing efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, where the diameters of various pistons differ, making it difficult to install tooling for pistons of different sizes and thus reducing efficiency, this invention proposes a piston-pressing tooling.

[0023] 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 scope of protection of the present utility model.

[0024] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0025] This application discloses a piston-pressing tooling. (Refer to...) Figure 1-5 A piston-pressing fixture includes a hollow block 1, a first fixing block 2 fixedly connected to one side of the hollow block 1, a cylinder 3 fixedly connected to the inner cavity of the first fixing block 2, a piston block 5 disposed on one side of the hollow block 1, a piston cylinder 4 disposed on one side of the piston block 5, and an adjustment mechanism 6 disposed on the surface of the piston cylinder 4. The hollow block 1 can be connected to the cylinder 3 through the first fixing block 2, so that the cylinder 3 can be located on one side of the piston block 5, while the piston block 5 is located between the cylinder 3 and the piston cylinder 4. The piston block 5 can be pushed and moved into the interior of the piston block 5 by the cylinder 3, thereby realizing the installation of the piston block 5.

[0026] The adjustment mechanism 6 includes a disc 601, the surface of which is rotatably connected to the inner cavity of the hollow block 1. A planar threaded block 602 is fixedly connected to one side of the disc 601. A slider 604 is provided on one side of the planar threaded block 602. A groove 603 is provided on the surface of the hollow block 1. One side of the slider 604 is slidably connected to the inner cavity of the groove 603. A limit rod 605 is fixedly connected to one side of the slider 604. A connecting block 606 is fixedly connected to one side of the limit rod 605. An L-shaped fixing rod 607 is provided on the surface of the piston cylinder 4. One side of the L-shaped fixing rod 607 is fixedly connected to one side of the connecting block 606.

[0027] The disc 601 can rotate within the cavity of the hollow block 1, while the planar threaded block 602 can be rotated together by the disc 601. The slider 604 can be moved by the rotating planar threaded block 602. The cavity of the groove 603 can be used to install the slider 604 and limit its movement, allowing the slider 604 to move smoothly when the planar threaded block 602 rotates. When the slider 604 moves, it can drive the limiting rod 605 to move together. Multiple sliders 604 and limiting rods 605 are provided, allowing the piston block 5 to be placed between the multiple limiting rods 605. The slider 604 moves, allowing the limiting rod 605 to support and place piston blocks 5 of different diameters. The connecting block 606 connects the limiting rod 605 and the L-shaped fixing rod 607, stabilizing the L-shaped fixing rod 607 on one side of the hollow block 1. The L-shaped fixing rod 607 can then hold the piston cylinder 4, stabilizing it on one side of the piston block 5. This allows the piston block 5 to be smoothly pushed into the piston cylinder 4. Simultaneously, the L-shaped fixing rod 607 can also be moved by the limiting rod 605, enabling it to support and place piston cylinders 4 of different sizes.

[0028] Reference Figure 3 A fixed shaft 7 is fixedly connected to the inner cavity of the hollow block 1. A first gear 8 is rotatably connected to the surface of the fixed shaft 7. A second gear 9 is fixedly connected to one side of the disc 601. The teeth of the second gear 9 mesh with the teeth of the first gear 8. The fixed shaft 7 can be used to connect the first gear 8, so that the first gear 8 can be stably placed on the outside of the hollow block 1 and rotate. The second gear 9 is connected to one side of the disc 601 and meshes with the first gear 8, so that when the first gear 8 rotates, it can drive the disc 601 to rotate together through the second gear 9, which makes the rotation of the disc 601 more convenient.

[0029] Reference Figure 4The hollow block 1 has a hollow groove 10 in its inner cavity. A limiting block 11 is slidably connected to the inner cavity of the hollow groove 10. One side of the limiting block 11 is fixedly connected to one side of the slider 604. The hollow groove 10 can limit the slider 604 through the limiting block 11, so that the slider 604 is not easy to get out when sliding in the inner cavity of the groove 603, and the stability is better.

[0030] Reference Figure 3 The hollow block 1 has an installation groove 12 in its inner cavity. The inner cavity of the installation groove 12 is rotatably connected to a ball bearing 13. The inside of the installation groove 12 can be used to install the ball bearing 13. The ball bearing 13 is located on the surface of the disc 601, which allows the disc 601 to rotate more smoothly and easily in the inner cavity of the hollow block 1, and it is less likely to cause a feeling of blockage.

[0031] Reference Figure 3 A second fixing block 14 is fixedly connected to the surface of the hollow block 1. A threaded rod 15 is threadedly connected to the inner cavity of the second fixing block 14. A rubber pad 16 is fixedly connected to one side of the threaded rod 15. The inner cavity of the second fixing block 14 can be used to install the threaded rod 15, which can be moved by rotation. After moving, it presses against the first gear 8, making it difficult for the first gear 8 to rotate. Consequently, the second gear 9, the disc 601, and the limiting rod 605 are all difficult to move, improving stability. The rubber pad 16 has greater friction, making it even more difficult for the first gear 8 to rotate when the threaded rod 15 presses against it.

[0032] Reference Figure 2-3 A reinforcing rod 17 is fixedly connected to one side of the slider 604. One side of the reinforcing rod 17 is fixedly connected to one side of the connecting block 606. The reinforcing rod 17 can reinforce the connection of the limiting rod 605, making the limiting rod 605 more secure on one side of the slider 604 and less prone to deformation and breakage.

[0033] Reference Figure 1 A support plate 18 is fixedly connected to one side of the hollow block 1. The surface of the support plate 18 is provided with a threaded hole 19. The support plate 18 can prevent the hollow block 1 from tipping over when it is placed on the platform. The support plate 18 and the hollow block 1 can be fixed to the platform by bolts inside the threaded hole 19.

[0034] Working principle: When using this device, first place the piston block 5 on multiple limiting rods 605, then place the piston cylinder 4 on multiple L-shaped fixing rods 607. Then, rotate the first gear 8 to drive the second gear 9 to rotate. The second gear 9 will drive the disc 601 to rotate together, and the disc 601 will drive the planar threaded block 602 to rotate. Then, the planar threaded block 602 can drive the slider 604 to slide inside the slide groove 603. At the same time, the slider 604 will drive the multiple limiting rods 605 to move, so that the multiple limiting rods 605 can support different straight rods by moving. The piston block 5 of different diameters is moved along with the limiting rod 605, which in turn moves the connecting block 606 and the L-shaped fixing rod 607. The L-shaped fixing rod 607 can support and fix the piston cylinder 4, and can also support piston cylinders 4 of different sizes by moving. Then, the cylinder 3 can be activated to push and move the piston block 5, allowing the piston block 5 to move into the interior of the piston cylinder 4 for installation. This solves the problem that the diameters of the piston blocks 5 are different, making it difficult for the tooling to install piston blocks 5 of different sizes, thus reducing the efficiency of use.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
