Description

Technical Field

[0001] The invention belongs to the technical field of engine manufacturing, in particular to a universal bowl-type plug assembly tool. Background Art

[0002] An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines, external combustion engines, jet engines, electric motors, etc. For example, an internal combustion engine usually converts chemical energy into mechanical energy. The engine is applicable to both power generation devices and the entire machine including the power device. The engine was first born in the UK, so the concept of engine also originated from English, and its original meaning refers to the "mechanical device that generates power."

[0003] An internal combustion engine is a power machine. It is a heat engine that burns fuel inside the machine and converts the heat energy released directly into power. In a broad sense, internal combustion engines include not only reciprocating piston internal combustion engines, rotary piston engines and free piston engines, but also rotary impeller jet engines, but the internal combustion engine usually refers to piston internal combustion engines. The reciprocating piston type is the most common piston internal combustion engine. The piston internal combustion engine mixes fuel and air and burns them in its cylinder. The heat energy released causes high-temperature and high-pressure combustion gas to be generated in the cylinder. The expansion of the combustion gas pushes the piston to work, and then the mechanical work is output through the crank-connecting rod mechanism or other mechanisms to drive the driven machine to work. Common ones include diesel engines and gasoline engines, which convert internal energy into mechanical energy, that is, changing internal energy by doing work.

[0004] During the assembly process of the internal combustion engine, the water channel, oil channel of the engine body and the air channel of the cylinder head need to use bowl-shaped plugs of different specifications. In order to facilitate people to quickly assemble the bowl-shaped plugs, people invented bowl-shaped plug assembly tools;

[0005] However, research has found that existing bowl-type plug assembly tools have certain drawbacks when used;

[0006] 1. The existing bowl-shaped plug assembly tools can only be used for the assembly of bowl-shaped plugs of one size. Due to assembly line production, bowl-shaped plugs of different specifications sometimes need to be assembled at the same position. Frequent switching of bowl-shaped plug assembly tools of different specifications results in a waste of costs in the production process.

[0007] 2. When the existing bowl-shaped plug assembly tool is used, the bowl-shaped plug is directly put on the bowl-shaped plug assembly tool and knocked. The bowl-shaped plug will slip when knocked, which may easily cause the bowl-shaped plug to be transferred to the wrong position and the assembly accuracy is not high. Summary of the invention

[0008] In order to overcome the shortcomings of the prior art, an embodiment of the present application provides a universal bowl-shaped plug assembly tool. The device is capable of meeting the assembly requirements of different bowl-shaped plugs by setting several groups of assembly steps with different sizes, thereby achieving the technical effect that bowl-shaped plugs of different specifications can be assembled using the same assembly air hammer.

[0009] The technical solution adopted by the embodiment of the present application to solve the technical problem is:

[0010] A universal bowl plug assembly tool, comprising:

[0011] An assembly rod, the assembly rod is mounted on an air hammer, and the air hammer drives the assembly rod to perform impact movement;

[0012] An assembly head, the assembly head contacts the bowl-shaped plug and knocks the bowl-shaped plug into the water channel, the oil channel and the air channel of the cylinder head. The assembly head is fixed to one end of the assembly rod. A plurality of groups of assembly steps are coaxially arranged on the assembly head, and the diameters of the plurality of groups of assembly steps are not equal.

[0013] Wherein, the bowl-shaped plug is mounted on an assembly step, and assembly steps of different diameters are suitable for mounting bowl-shaped plugs of different sizes.

[0014] Preferably, the diameter of the assembly step far from the assembly rod position is smaller than the diameter of the assembly step close to the assembly rod position, and the diameter of the assembly step changes gradually along one direction.

[0015] Preferably, the assembly step includes a first limit step and a second limit step installed on the first limit step away from the assembly rod. The bowl-shaped plug is sleeved on the second limit step. Like the existing bowl-shaped plug assembly tool, the first limit step limits the depth of the bowl-shaped plug knocked into the water channel, oil channel and air channel of the cylinder head.

[0016] Preferably, the diameter of the second limiting step is smaller than the diameter of the first limiting step.

[0017] Preferably, a magnetic attraction component that is magnetically attracted to the bowl-shaped plug is provided on the end surface of the second limiting step away from the assembly rod.

[0018] The magnetic attraction component is magnetically attracted to the bowl-shaped plug, which can preliminarily limit the position of the bowl-shaped plug and improve the stability of the bowl-shaped plug during the knocking process.

[0019] Preferably, the magnetic attraction component adopts a magnetic attraction ring, which can adsorb the end face of the bowl-shaped plug, thereby improving the stability of the bowl-shaped plug after installation. The magnetic attraction ring is embedded and fixedly installed on the end face of the second limiting step away from the assembly rod. The embedded setting of the magnetic attraction ring can reduce wear and extend the service life of the magnetic attraction ring.

[0020] The magnetic suction component can also be replaced by several groups of magnet blocks. Several groups of magnet blocks are evenly distributed, which can achieve the effect of adsorbing the bowl-shaped plug.

[0021] The magnetic component mainly plays an adsorption effect, and components with adsorption effect, such as suction cups, can also be used.

[0022] Preferably, a plurality of groups of the second limiting steps are each provided with a limiting component for limiting the position of the bowl-shaped plug.

[0023] Preferably, the limiting assembly includes several groups of limiting members, and the several groups of limiting members are fixedly installed in the installation grooves opened on the outer surface of the second limiting step. The setting of the installation grooves can play the role of protecting the limiting members, and the several groups of limiting members are arranged in a ring shape with equal spacing.

[0024] Preferably, the limiting member adopts a spring plunger, one end of which is located outside the mounting groove, the spring plunger contacts the inner surface of the bowl-shaped plug, and the spring plunger elastically supports the bowl-shaped plug, thereby further limiting the position of the bowl-shaped plug, so that the bowl-shaped plug will not shake during the knocking process, making the knocking more precise.

[0025] The spring plunger can also be directly replaced by a bump or a convex point, or by an elastic clip. The elastic clip and the spring plunger have a certain elasticity, which can reduce the deformation of the edge of the bowl-shaped plug when it is installed.

[0026] In summary, the present invention includes at least one of the following beneficial technical effects:

[0027] First, a universal bowl-shaped plug assembly tool of the present invention is provided with a plurality of groups of assembly steps of different diameters on its assembly head, and the assembly steps of different diameters can meet the assembly requirements of different bowl-shaped plugs, so that bowl-shaped plugs of different specifications can be assembled using the same bowl-shaped plug assembly tool, which can save the waste of time caused by changing tools back and forth, and can save the cost of purchasing bowl-shaped plug tools at the post.

[0028] Second, a limiting component for limiting the position of the bowl-shaped plug is provided on the second limiting step of a universal bowl-shaped plug assembly tool of the present invention. When in use, the limiting component contacts the bowl-shaped plug so that the bowl-shaped plug is stuck on the second limiting step, which can improve the stability of the bowl-shaped plug and prevent the bowl-shaped plug from loosening during knocking, thereby improving the installation accuracy of the bowl-shaped plug.

[0034] The embodiment of the present application provides a universal bowl-shaped plug assembly tool to solve the problem that the existing bowl-shaped plug assembly tool in the prior art can only be used for the assembly of bowl-shaped plugs of one size. Due to assembly line production, bowl-shaped plugs of different specifications sometimes need to be assembled at the same position. Frequent switching of bowl-shaped plug assembly tools of different specifications causes waste of costs in the production process. In the universal bowl-shaped plug assembly tool, a plurality of groups of assembly steps of different diameters are arranged on the assembly head. The assembly steps of different diameters can meet the assembly requirements of different bowl-shaped plugs, so that bowl-shaped plugs of different specifications can be assembled using the same bowl-shaped plug assembly tool, which can save the time waste caused by changing tools back and forth and can save the cost of purchasing bowl-shaped plug tools at the position.

[0035] Embodiment 1:

[0036] A universal bowl plug assembly tool, such as Figure 1-Figure 4 As shown, it includes an assembly rod 1 and an assembly head 2. The assembly head 2 is integrally formed with one end of the assembly rod 1. The assembly rod 1 is assembled on an air hammer. The air hammer drives the assembly rod 1 to move, so that the assembly head 2 strikes the bowl-shaped plug, thereby realizing the installation of the bowl-shaped plug.

[0037] Among them, several groups of assembly steps are coaxially installed on the assembly head 2, and the diameters of the several groups of assembly steps are not equal. The diameters of the several groups of assembly steps gradually decrease as they move away from the assembly rod 1, so that bowl-shaped plugs of different sizes can be easily installed;

[0038] Among them, the bowl-shaped plug is sleeved on the assembly step, and after being sleeved and clamped on the assembly step, the position of the bowl-shaped plug can be preliminarily limited.

[0039] When in use, install the assembly rod 1 on the air hammer and fix it, then put the bowl-shaped plug on the assembly step, align it with the water channel, oil channel of the machine body and the air channel of the cylinder head, start the air hammer, and install the bowl-shaped plug;

[0040] When installing bowl plugs of different specifications, the bowl plugs are stuck on assembly steps of different diameters.

[0041] The diameter of the assembly step at a position far from the assembly rod 1 is smaller than the diameter of the assembly step at a position close to the assembly rod 1 .

[0042] The assembly step includes a first limit step 3 and a second limit step 4 installed at a position of the first limit step 3 away from the assembly rod 1. The first limit step 3 and the second limit step 4 are coaxial, and the bowl-shaped plug is sleeved on the second limit step 4. When the bowl-shaped plug is sleeved, it is stuck on the second limit step 4 and will not loosen.

[0043] The diameter of the second limiting step 4 is smaller than that of the first limiting step 3, and has the same function as the existing bowl-shaped plug assembly tool. When in use, the first limiting step 3 limits the depth of the limiting bowl-shaped plug knocked into the water channel, oil channel and air channel of the cylinder head.

[0044] The assembly head 2 of a universal bowl-shaped plug assembly tool of the present invention is provided with a plurality of groups of assembly steps of different diameters. The assembly steps of different diameters can meet the assembly requirements of different bowl-shaped plugs, so that bowl-shaped plugs of different specifications can be assembled using the same bowl-shaped plug assembly tool, which can save the waste of time caused by changing tools back and forth and can save the cost of purchasing bowl-shaped plug tools at the post.

[0045] Embodiment 2:

[0046] On the basis of Example 1, Figure 1-Figure 4 As shown, this embodiment is a limiting structure of a bowl-shaped plug.

[0047] The end surface of the second limiting step 4 away from the assembly rod 1 is provided with a magnetic attraction component which is magnetically attracted to the bowl-shaped plug.

[0048] The magnetic suction component has the effect of absorbing the bowl-shaped plug, which can prevent the bowl-shaped plug from loosening, thereby making the bowl-shaped plug more accurate during installation.

[0049] The magnetic attraction component adopts a magnetic attraction ring 5 , and the magnetic attraction ring 5 is embedded in the end surface of the second limiting step 4 away from the assembly rod 1 .

[0050] The magnetic attraction component can also use magnet blocks, which are evenly distributed. The magnet blocks and the magnetic attraction ring 5 use nepidium magnets, which have strong magnetic force and good adsorption effect. Other existing adsorption structures can also be used as substitutes.

[0051] A plurality of groups of second limiting steps 4 are each provided with a limiting component for limiting the position of the bowl-shaped plug.

[0052] The limiting assembly includes a plurality of groups of limiting members, which are respectively installed in a plurality of groups of mounting grooves provided on the outer surface of the second limiting step 4, and the plurality of groups of limiting members are arranged in a ring shape with equal intervals.

[0053] The limiting member adopts a spring plunger 6, one end of which is located outside the installation groove, squeezing the bowl-shaped plug and applying pressure to the bowl-shaped plug, thereby improving the stability of the bowl-shaped plug and avoiding the loosening of the bowl-shaped plug during installation, thereby effectively improving the installation accuracy of the bowl-shaped plug.

[0054] When a small bowl-shaped plug is installed, the magnetic ring 5 will be adsorbed on it and contact the limiting components on the second limiting steps 4 with the magnetic ring 5, further improving the installation stability of the bowl-shaped plug. When a large bowl-shaped plug is installed, it will contact the limiting components on the second limiting steps 4 at other positions to improve stability.

[0055] A limiting component for limiting the position of the bowl-shaped plug is provided on the second limiting step of a universal bowl-shaped plug assembly tool of the present invention. When in use, the limiting component contacts the bowl-shaped plug so that the bowl-shaped plug is stuck on the second limiting step, which can improve the stability of the bowl-shaped plug and prevent the bowl-shaped plug from loosening during knocking, thereby improving the installation accuracy of the bowl-shaped plug.

[0056] It should be noted that when in use, the assembly rod 1 is installed on the air hammer and fixed, and then the bowl-shaped plug is put on the assembly step, aligned with the water channel, oil channel of the machine body and the air channel of the cylinder head, and the air hammer is started to install the bowl-shaped plug.

[0057] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
