Description

Technical Field

[0001] This utility model relates to the technical field of an adjustable-size universal automotive piston ring installation tool, specifically an adjustable-size universal automotive piston ring installation tool. Background Technology

[0002] The engine is the heart of a car. An engine is a machine that converts other forms of energy into mechanical energy, including internal combustion engines, external combustion engines, jet engines, and electric motors. For example, internal combustion engines typically convert chemical energy into mechanical energy. The term "engine" can refer to both the power generating device and the entire machine including the power unit. In the automotive repair industry or automotive repair vocational education, there are often major overhauls of automotive engines or teaching activities on disassembling and assembling automotive engines. When installing engine pistons, the pistons cannot be installed into the cylinder because the diameter of the elastic piston rings is larger than the cylinder diameter, which presents a problem.

[0003] Typically, piston rings are positioned using an annular iron pipe. However, due to the wide variety of piston ring sizes, the annular iron pipe, which is difficult to adjust in size, is unsuitable for fixing piston rings of different sizes, leading to inconvenience in piston ring installation. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable-size universal automotive piston ring installation tool to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides an adjustable universal automotive piston ring installation tool, including a base and a positioning seat. A positioning pin is movably fitted inside the base, and a turntable is movably fitted inside the positioning seat. A spiral guide rail is fixedly connected to the top of the turntable, and a positioning block is movably fitted inside the spiral guide rail. A pawl is fixedly connected to the top of the positioning block, and a positioning rod is fixedly connected to the top of the pawl. A gear ring is fixedly connected to the bottom of the turntable. A rotating shaft is movably fitted inside the base, and a gear is fixedly fitted to the top of the rotating shaft. An anti-slip toothed sleeve is fixedly fitted to the bottom of the rotating shaft. A limit mechanism is provided inside the base.

[0006] Preferably, the gear ring is meshed with a gear, and the gear ring is located directly below the turntable.

[0007] Preferably, the claw is movably sleeved inside the positioning seat, and the front shape of the claw is I-shaped.

[0008] Preferably, the diameter of the anti-slip toothed sleeve is smaller than the diameter of the toothed ring, and the anti-slip toothed sleeve is made of stainless steel.

[0009] Preferably, the limiting mechanism includes a limiting sleeve, which is fixedly connected to the bottom of the inner cavity of the positioning seat. A sliding post is movably sleeved inside the toothed ring, and the number of sliding posts is several, which are evenly distributed around the limiting sleeve inside the toothed ring.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This adjustable universal automotive piston ring installation tool, by setting a gear ring, allows the piston ring to be fitted onto the outside of multiple positioning rods when different sizes of piston rings need to be installed. At this time, rotating the rotating shaft causes the gear ring to rotate through the gear, which in turn drives the spiral guide rail to rotate. This causes the spiral guide rail to drive multiple claws to move radially through the positioning blocks, thereby causing multiple positioning rods to spread out and fix the piston rings on the outside of the multiple positioning rods, thus achieving the fixing effect of piston rings of different sizes, and bringing convenience to the installation of piston rings of multiple specifications. In addition, this adjustable-size universal automotive piston ring installation tool also features a limiting mechanism. When the gear drives the gear ring to rotate, the limiting sleeve can limit the rotating gear ring through the sliding pin, that is, limit the rotating spiral guide rail, thereby improving the stability and smoothness of the spiral guide rail rotation, and thus improving the smoothness of piston ring fixing.

[0018] Please see Figure 1-5 An embodiment of this utility model provides: an adjustable-size universal automotive piston ring installation tool, including a base 1 and a positioning seat 2. A positioning post 3 is movably sleeved inside the base 1. A turntable 4 is movably sleeved inside the positioning seat 2. A spiral guide rail 5 is fixedly connected to the top of the turntable 4. A positioning block 6 is movably sleeved inside the spiral guide rail 5. A pawl 7 is fixedly connected to the top of the positioning block 6. A positioning rod 8 is fixedly connected to the top of the pawl 7. A gear ring 9 is fixedly connected to the bottom of the turntable 4. A rotating shaft 10 is movably sleeved inside the base 1. A gear 11 is fixedly sleeved to the top of the rotating shaft 10. An anti-slip toothed sleeve 12 is fixedly sleeved to the bottom of the rotating shaft 10. A limit mechanism 13 is provided inside the base 1.

[0019] The gear ring 9 meshes with the gear 11, and the gear ring 9 is located directly below the turntable 4. By setting the gear ring 9, when piston rings of different sizes need to be installed, the piston rings are fitted onto the outside of multiple positioning rods 8. At this time, the rotating shaft 10 is rotated, so that the rotating shaft 10 drives the gear ring 9 to rotate through the gear 11, that is, the turntable 4 drives the spiral guide rail 5 to rotate, so that the spiral guide rail 5 drives multiple claws 7 to move radially through the positioning block 6, thereby causing multiple positioning rods 8 to spread out, so that the piston rings can be fixed and stuck on the outside of multiple positioning rods 8, thus achieving the fixing effect of piston rings of different sizes, thereby bringing convenience to the installation of piston rings of multiple specifications.

[0020] The chuck 7 is movably sleeved inside the positioning seat 2, and the front of the chuck 7 is I-shaped. By setting the chuck 7, when the spiral guide rail 5 drives the chuck 7 to move radially through the positioning block 6, the positioning seat 2 can limit the moving chuck 7, thereby avoiding the problem of rotation when the spiral guide rail 5 drives the chuck 7 to move radially, thus improving the stability of the chuck 7 when it moves.

[0021] The diameter of the anti-slip toothed sleeve 12 is smaller than that of the toothed ring 9, and the anti-slip toothed sleeve 12 is made of stainless steel. By setting the anti-slip toothed sleeve 12, when the position of the positioning rod 8 needs to be adjusted, the anti-slip toothed sleeve 12 can be manually rotated, so that the anti-slip toothed sleeve 12 can drive the gear 11 to rotate through the rotating shaft 10. This avoids the problem that the rotating shaft 10 is too small to rotate manually, thereby improving the convenience of manually rotating the toothed ring 9, that is, improving the convenience of manually adjusting the position of the positioning rod 8.

[0022] The limiting mechanism 13 includes a limiting sleeve 131, which is fixedly connected to the bottom of the inner cavity of the positioning seat 2. A sliding post 132 is movably sleeved inside the gear ring 9. There are several sliding posts 132, which are evenly distributed around the limiting sleeve 131 inside the gear ring 9. By setting the limiting mechanism 13, when the gear 11 drives the gear ring 9 to rotate, the limiting sleeve 131 can limit the rotating gear ring 9 through the sliding posts 132, that is, limit the rotating spiral guide rail 5, thereby improving the stability and smoothness of the spiral guide rail 5 when rotating, that is, improving the smoothness of the piston ring fixing.

[0023] Working principle: When installing piston rings of different sizes, the piston rings are fitted onto the outside of multiple positioning rods 8. Rotating the rotating shaft 10 causes the gear ring 9 to rotate via the gear 11, which in turn drives the helical guide rail 5 to rotate via the turntable 4. This causes the helical guide rail 5 to move radially via the positioning block 6, thereby causing the multiple positioning rods 8 to spread out and secure the piston rings to the outside of the positioning rods 8. This achieves the fixing effect for piston rings of different sizes, facilitating the installation of piston rings of various sizes. When the helical guide rail 5 moves radially via the positioning block 6, the positioning seat 2 limits the movement of the pawls 7, preventing rotation during the radial movement of the helical guide rail 5 and the pawls 7. This addresses the issue of the stability of the pawl 7 during movement. When the position of the positioning rod 8 needs to be adjusted, the anti-slip toothed sleeve 12 is manually rotated, allowing the anti-slip toothed sleeve 12 to drive the gear 11 to rotate via the rotating shaft 10. This avoids the problem of the rotating shaft 10 having a small diameter and being difficult to rotate manually, thus improving the convenience of manually rotating the gear ring 9, i.e., improving the convenience of manually adjusting the position of the positioning rod 8. When the gear 11 drives the gear ring 9 to rotate, the limiting sleeve 131 can limit the rotating gear ring 9 via the sliding column 132, i.e., limit the rotating spiral guide rail 5, thereby improving the stability and smoothness of the spiral guide rail 5 during rotation, i.e., improving the smoothness of piston ring fixing. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0024] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
