Description

Technical Field

[0001] This application relates to the technical field of plugging tools, and more specifically, to a pneumatic gun plugging tool that is convenient for replacement. Background Art

[0002] In traditional cylinder block designs, sand cleaning holes are added on the top or side of the cylinder block to ensure that the sand in the water jacket and lubricating oil passage can be cleaned thoroughly. After the sand cleaning work is completed, the sand cleaning holes are trimmed, and then the sand cleaning holes are plugged with bowl-shaped plugs, which is called the plugging operation. Specifically, during the operation, a tool needs to be installed on the pneumatic gun, and then this tool is used to drive the bowl-shaped plug onto the orifice of the sand cleaning hole.

[0003] This tool includes a pressure head and a pressure rod, which are generally integrally formed. The pressure rod is used to connect to the pneumatic gun, and the pressure head is used to connect to the bowl-shaped plug. In actual plugging operations, because the impact force of the pneumatic gun is very strong, the pressure rod is often prone to breakage or deformation. Once the pressure rod breaks, the entire plugging tool has to be scrapped. Moreover, in order to adapt to different specifications of bowl-shaped plugs, multiple specifications of tools need to be customized, resulting in a high cost. Summary of the Invention

[0004] In order to overcome the existing deficiencies, the embodiments of this application provide a pneumatic gun plugging tool that is convenient for replacement, which can solve the problems that the entire tool is scrapped due to damage to the pressure rod and the high cost caused by the need to customize the entire tool for each of the multiple specifications of bowl-shaped plugs mentioned in the above background art.

[0005] The technical solution adopted by the embodiments of this application to solve its technical problems is: a pneumatic gun plugging tool that is convenient for replacement, including a head assembly and a rod assembly.

[0006] The head assembly includes a pressure head and a threaded hole. The threaded hole is opened at one end of the pressure head. The other end of the pressure head is movably connected to an external bowl-shaped plug. The rod assembly includes a threaded rod and a rod body. The threaded rod is fixedly connected to one end of the rod body. The other end of the rod body is movably connected to an external pneumatic gun. The threaded rod is screwed to the pressure head through the threaded hole, and the end face of the rod body abuts against the end face of the pressure head.

[0007] In a specific implementation, the head assembly further includes an annular convex ring, and the convex ring is fixedly connected to the outer circle of the pressure head.

[0008] In a specific implementation, flat positions are opened on both sides of the outer circle of the convex ring.

[0009] In a specific implementation, a root cleaning groove is opened at the root of the threaded rod.

[0010] In a specific embodiment, the rod body includes a head section, a middle section, and a tail section. The head section, the middle section, and the tail section are integrally formed. The outer diameter of the middle section is larger than that of the tail section, and the outer diameter of the middle section is smaller than that of the head section.

[0011] In a specific embodiment, flat positions are provided on both sides of the outer circle of the head section.

[0012] In a specific embodiment, a limiting ring is provided between the tail section and the middle section, and the limiting ring is movably pressed against an external air gun.

[0013] In a specific embodiment, both between the head section and the middle section and on both sides of the limiting ring are provided with inverted arcs.

[0014] The advantages of the embodiments of the present application are as follows:

[0015] The present application utilizes the screwing connection between the threaded rod and the threaded hole to detachably connect the pressing head and the rod body together, so that when one of the components is damaged, it can be replaced at any time without scrapping the whole, and the head component can be easily replaced with different specifications to adapt to different types of bowl-shaped plugs, and the rod body can be universal, reducing the cost.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The technical solutions in the embodiments of the present application are to solve the problems that the entire tooling is scrapped after the damage of the pressure rod and that the bowl-shaped plugs have many specifications and all need to customize the overall tooling one by one, resulting in high costs in the above-mentioned background technology. The general idea is as follows:

[0022] Please refer to Figure 1, A convenient-to-replace air gun plugging tooling, including a head component 100 and a rod component 200.

[0023] Among them, the head component 100 and the rod component 200 are fixedly connected by means of threads, so that when one of the components is damaged, it can be replaced at any time without the need to scrap the whole. Moreover, the head component 100 can easily replace the punches 110 of different specifications to adapt to different models of bowl-shaped plugs, and the rod body 220 can be universal, reducing the cost.

[0024] Please refer to Figures 1-4 , The head component 100 includes a punch 110 and a threaded hole 120. The threaded hole 120 is opened at one end of the punch 110, and the other end of the punch 110 is movably connected to an external bowl-shaped plug. The rod component 200 includes a threaded rod 210 and a rod body 220. The threaded rod 210 is fixedly connected to one end of the rod body 220, and the other end of the rod body 220 is movably connected to an external air gun. The threaded rod 210 is screwed to the punch 110 through the threaded hole 120, and the end face of the rod body 220 abuts against the end face of the punch 110. Here, through the screwing connection of the threaded rod 210 and the threaded hole 120, the punch 110 and the rod body 220 are connected together, and then the bowl-shaped plug is punched on the orifice of the cleaning hole of the cylinder block by using the punch 110 to block the cleaning hole. When the rod body 220 or the punch 110 is damaged, only the rod body 220 or the punch 110 needs to be replaced separately. Moreover, the punch 110 can easily replace different specifications and sizes to adapt to different models of bowl-shaped plugs, with stronger universality. In summary, the head component 100 and the rod component 200 are fixedly connected by means of threads, so that when one of the components is damaged, it can be replaced at any time without the need to scrap the whole. Moreover, the head component 100 can easily replace the punches 110 of different specifications to adapt to different models of bowl-shaped plugs, and the rod body 220 can be universal, reducing the cost.

[0025] Please refer to Figures 1-3 , The head component 100 further includes an annular convex ring 130, and the convex ring 130 is fixedly connected to the outer circle of the punch 110. Here, since the impact force of the air gun is very strong, an additional convex ring 130 is added to improve the rigidity of the punch 110, reduce deformation caused by long-term use, and improve durability.

[0026] Please refer to Figures 1-3 , Flat positions are opened on both sides of the outer circle of the convex ring 130. Here, the flat positions are used for clamping external tools such as wrenches, facilitating the screwing and fastening of the punch 110 and the rod body 220.

[0027] Please refer to Figure 2, a root clearance groove 230 is provided at the root of the threaded rod 210. Here, during the machining of the thread, due to the interference between the cutting tool and the rod body 220, the thread cannot be machined at the root of the threaded rod 210, resulting in the pressing head 110 not being able to be screwed to the bottom. Therefore, the root clearance groove 230 is provided here so that the pressing head 110 can be screwed to the bottom, in order for the end face of the pressing head 110 to fit with the end face of the rod body 220.

[0028] Please refer to Figures 1-2 , the rod body 220 includes a head section 221, a middle section 222 and a tail section 223. The head section 221, the middle section 222 and the tail section 223 are integrally formed. The outer diameter of the middle section 222 is larger than that of the tail section 223, and the outer diameter of the middle section 222 is smaller than that of the head section 221. Here, the rod body 220 needs a certain length for convenient use, so it is set in a pagoda shape. While ensuring the structural strength, the weight is reduced as much as possible. The head section 221 has the largest outer diameter to ensure that there is enough end face area to contact the end face of the pressing head 110, which is convenient for the transmission of force, and the tail section 223 is used to connect with an external air gun.

[0029] Please refer to Figures 1-4 , flat positions are provided on both sides of the outer circle of the head section 221. Here, the flat positions of the head section 221 and the pressing head 110 have the same function, which are both used for the clamping of external tools such as wrenches, so as to screw and fasten the pressing head 110 and the rod body 220.

[0030] Please refer to Figures 1-2 , a limiting ring 224 is provided between the tail section 223 and the middle section 222, and the limiting ring 224 is movably abutted against an external air gun. Here, the limiting ring 224 is used to abut against the mouth of the external air gun to ensure that the entire tail section 223 is inserted into the air gun, and the limiting ring 224 is also used to receive the axial impact force of the air gun.

[0031] Please refer to Figures 1-2 , arc chamfers are provided between the head section 221 and the middle section 222 and on both sides of the limiting ring 224. Here, the arc chamfers are used for the connection of the head section 221, the middle section 222 and the tail section 223. Because the stress is most concentrated at the connection position and is prone to fracture, an arc transition is adopted to facilitate stress dispersion and reduce the fracture situation.

[0032] When this application is used: By screwing the threaded rod 210 with the threaded hole 120, the pressing head 110 is connected to the rod body 220. Then, the bowl-shaped plug is punched at the orifice of the sand cleaning hole of the cylinder block by using the pressing head 110 to block the sand cleaning hole. When the rod body 220 or the pressing head 110 is damaged, only the rod body 220 or the pressing head 110 needs to be replaced separately. Moreover, the pressing head 110 can be easily replaced with different specifications and sizes to adapt to different types of bowl-shaped plugs, and the rod body 220 can be universal, reducing the cost.

[0033] In summary, in the present application, the pressing head 110 and the rod body 220 are detachably connected together by screwing the threaded rod 210 into the threaded hole 120, so that when one of the components is damaged, it can be replaced at any time without scrapping the whole, and the head component 100 can be easily replaced with different specifications to adapt to different types of bowl-shaped plugs, while the rod body 220 can be universal, reducing the cost.

[0034] Finally, it should be noted that: Obviously, the above embodiments are merely examples for clearly illustrating the present invention and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the present invention.
