Description

Technical Field

[0001] The present disclosure relates to the technical field of engines, and in particular, to a process plug for an oil passage hole on the side of an engine block. Background Art

[0002] Under normal circumstances, the oil passage hole on the side of the engine block in an engine is used to install a turbine return oil pipe. However, during cold testing, a process plug needs to be installed in this oil passage hole on the side of the engine block to meet the requirements of cold testing. However, the existing process plugs need to be manually disassembled using tools during use, and the operation is very inconvenient, which is specifically reflected in the following aspects:

[0003] 1. Due to the limited installation space, it is very inconvenient to install the process plug. The bolts often skew during pre-tightening. If a pneumatic wrench is used to tighten it later, the threads are very likely to be damaged, increasing the loss.

[0004] 2. When installing this kind of process plug in the related art, the engine needs to be rotated 180°. Then, while the operator bends down, one hand holds the process plug firmly in place, and the other hand pre-tightens the process plug. However, due to the narrow position where the process plug is installed on the engine, the installation is very inconvenient and extremely time-consuming, seriously affecting the production rhythm. Summary of the Invention

[0005] The purpose of the present disclosure is to provide a process plug for an oil passage hole on the side of an engine block, which does not require additional auxiliary tools for disassembly during use and is convenient to operate.

[0006] To achieve the above object, the present disclosure provides a process plug for an oil passage hole on the side of an engine block, including: a process plug body having opposite first and second faces, a plugging head for plugging the oil passage hole on the side of the engine block being provided on the first face; an operating member including a long rod portion and a fastening portion connected to each other, the fastening portion passing through the process plug body from the second face and being used for fastening with a first turbine return oil pipe bolt mounting hole to fix the plugging head in the oil passage hole on the side of the engine block; and an auxiliary member fixed on the second face and extending in a direction away from the operating member.

[0007] Optionally, a stop end face is formed at the connection between the long rod portion and the fastening portion, and the fastening portion passes through the process plug body so that the stop end face abuts against the second face.

[0008] Optionally, the fastening portion is configured as a threaded fastening rod, the long rod portion is configured as an operating handle protruding circumferentially from the threaded fastening rod, a stop end face is formed at the connection between the threaded fastening rod and the operating handle, and the threaded fastening rod passes through the process plug body for threaded connection with the first turbo return oil pipe bolt mounting hole, so that the stop end face presses the plug head in the engine block side oil passage hole through the process plug body.

[0009] Optionally, the length of the operating handle ranges from 80 mm to 100 mm.

[0010] Optionally, the auxiliary member includes a fixing portion fixed on the second surface, and a holding portion is formed at one end of the fixing portion away from the operating member.

[0011] Optionally, the fixing portion is configured as a cross bar fixed on the second surface and extending horizontally in the transverse direction, the holding portion is configured as an inclined rod, the inclined rod is arranged at an angle with the cross bar and the inclined rod extends in a direction away from the second surface.

[0012] Optionally, the included angle between the inclined rod and the cross bar ranges from 120° to 140°; and / or, the length of the cross bar ranges from 40 mm to 60 mm; and / or, the length of the inclined rod ranges from 60 mm to 80 mm.

[0013] Optionally, an auxiliary convex block for cooperating with the second turbo return oil pipe bolt mounting hole is provided on the first surface.

[0014] Optionally, the plug head and the process plug body are integrally formed.

[0015] Optionally, the process plug for the engine block side oil passage hole further includes a sealing ring, and the sealing ring is sleeved on the plug head.

In this process, the operator can use one hand to operate the auxiliary member to press and hold the process plug body in the appropriate position, while using the other hand to operate the long rod portion of the operating member to fasten the fastening portion in the first turbo return oil pipe bolt mounting hole. In this way, through the mutual cooperation of both hands, the process plug body can be installed in the corresponding position, and finally the reliable plugging of the side oil passage hole of the engine cylinder block can be achieved through the plugging head. Among them, due to the setting of the long rod portion in the operating member and the setting that the auxiliary member extends away from the operating member, the operator can achieve the plugging of the side oil passage hole of the engine cylinder block during the cold test without borrowing additional auxiliary tools.

Detailed implementation manners

[0025] The following will describe in detail the detailed implementation manners of the present disclosure with reference to the accompanying drawings. It should be understood that the detailed implementation manners described herein are only for explaining and illustrating the present disclosure, and are not used to limit the present disclosure.

[0026] In the present disclosure, unless otherwise stated, the orientation terms such as "inside, outside" refer to "inside, outside" relative to the contour of the corresponding component itself. In addition, the terms "first", "second", etc. used in the present disclosure are used to distinguish one element from another element, and do not have sequentiality and importance. In addition, in the following description, when referring to the accompanying drawings, unless otherwise explained, the same reference numerals in different drawings represent the same or similar elements. The above definitions are only used to explain and illustrate the present disclosure, and should not be construed as a limitation to the present disclosure.

[0027] The present disclosure provides a process plug for an engine block side oil passage hole. Refer to Figures 1 to 4 As shown, the process plug for the engine block side oil passage hole includes: a process plug body 1, the process plug body 1 has opposite first surface 11 and second surface 12, and a plugging head 111 for plugging the engine block side oil passage hole 5 is provided on the first surface 11; an operating part 2, including a long rod part 22 and a fastening part 21 connected to each other, the fastening part 21 passes through the process plug body 1 from the second surface 12 and is used for fastening with the first turbine return oil pipe bolt mounting hole 6 to fix the plugging head 111 in the engine block side oil passage hole 5; and an auxiliary part 3, the auxiliary part 3 is fixed on the second surface 12, and the auxiliary part 3 extends in a direction away from the operating part 2.

[0028] With the above technical solution, in the process plug for the side oil passage hole of the engine cylinder block provided in the present disclosure, by operating the long rod portion 22 of the operating member 2, the fastening portion 21 passes through the process plug body 1 and is fastened to the first turbo return oil pipe bolt mounting hole 6 on the engine cylinder block 8, and at the same time, the plugging head 111 on the process plug body 1 is fixed in the engine cylinder block side oil passage hole 5, so as to finally achieve the plugging of the engine cylinder block side oil passage hole 5. In this process, the operator can use one hand to operate the auxiliary member 3 to press and hold the process plug body 1 in the appropriate position, while using the other hand to operate the long rod portion 22 of the operating member 2 to fasten the fastening portion 21 in the first turbo return oil pipe bolt mounting hole 6. In this way, through the mutual cooperation of both hands, the process plug body 1 can be installed in the corresponding position, and finally, the reliable plugging of the engine cylinder block side oil passage hole 5 can be achieved through the plugging head 111. Among them, due to the setting of the long rod portion 22 in the operating member 2 and the setting that the auxiliary member 3 extends in a direction away from the operating member 2, the operator can achieve the plugging of the engine cylinder block side oil passage hole 5 during the cold test without borrowing additional auxiliary tools. At the same time, this setting also enables the operator to form a relatively large operating space when operating the process plug body 1 relative to the engine cylinder block 8, thereby facilitating the installation and disassembly operations of the process plug for the engine cylinder block side oil passage hole.

[0029] In the specific embodiment provided by the present disclosure, with reference to Figure 3 and Figure 4 As shown, a stop end face 23 is formed at the connection between the long rod portion 22 and the fastening portion 21. The fastening portion 21 passes through the process plug body 1 so that the stop end face 23 abuts against the second face 12. Through such a setting, when the fastening portion 21 passes through the process plug body 1 and is fastened to the first turbo return oil pipe bolt mounting hole 6 on the engine cylinder block 8, the process plug body 1 can be pressed against the appropriate position on the engine cylinder block 8 through the setting of the stop end face 23. In this way, on the basis of the good plugging of the engine cylinder block side oil passage hole 5 by the plugging head 111, the plugging effect can be further improved.

[0030] In the specific embodiment provided by the present disclosure, both the fastening portion 21 and the long rod portion 22 can be constructed in any suitable manner. Optionally, with reference to Figure 3 and Figure 4 As shown, the fastening portion 21 is constructed as a threaded fastening rod, and the long rod portion 22 is constructed as an operating handle protruding circumferentially from the threaded fastening rod. A stop end face 23 is formed at the connection between the threaded fastening rod and the operating handle. The threaded fastening rod passes through the process plug body 1 for threaded connection with the first turbo return oil pipe bolt mounting hole 6, so that the stop end face 23 presses the plugging head 111 in the engine cylinder block side oil passage hole 5 through the process plug body 1, thereby further ensuring the good plugging of the engine cylinder block side oil passage hole 5 by the plugging head 111.

[0031] In the specific embodiments provided by the present disclosure, the length of the operating handle ranges from 80 mm to 100 mm. Through such a setting, it can be ensured that when the operator installs and disassembles the process plug for the side oil passage hole of the engine block of the present disclosure, the operating handle has a suitable length to facilitate the operator's gripping operation. Exemplarily, the length of the operating handle here can be 80 mm, 90 mm or 100 mm, or any value between these dimensions.

[0032] In the specific embodiments provided by the present disclosure, with reference to Figure 3 and Figure 4 As shown, in order to further facilitate the operator to install the process plug for the side oil passage hole of the engine block of the present disclosure into the side oil passage hole 5 of the engine block or disassemble it from the side oil passage hole 5 of the engine block, the auxiliary member 3 can be provided with a fixing portion 31 fixed on the second surface 12. A gripping portion 32 is formed at one end of the fixing portion 31 away from the operating member 2, so that there is a certain distance between the gripping portion 32 and the engine block 8. Thus, when the operator performs auxiliary installation or disassembly of the process plug for the side oil passage hole of the engine block through the gripping portion 32, there can be sufficient operating space.

[0033] Among them, the fixing portion 31 and the gripping portion 32 can be constructed in any suitable manner. For example, the fixing portion 31 is constructed as a long rod perpendicular to the second surface 12 of the process plug body 1, and the gripping portion 32 is constructed as a horizontal rod extending outward perpendicular to the long rod. Alternatively, with reference to Figure 3 and Figure 4 As shown, the fixing portion 31 is constructed as a cross bar fixed on the second surface 12 and extending horizontally in the transverse direction, and the gripping portion 32 is constructed as an inclined rod. The inclined rod and the cross bar are arranged at an angle and the inclined rod extends in a direction away from the second surface 12. Through such a setting, on the one hand, the contact area between the cross bar and the process plug body 1 can be increased, thus facilitating the fixed setting of the cross bar on the second surface 12 of the process plug body 1. On the other hand, sufficient space can be reserved between the gripping portion 32 and the engine block 8, thus making it more convenient for the operator to operate the gripping portion 32.

[0034] In the specific embodiments provided by the present disclosure, the range of the angle between the inclined rod and the cross bar and the relationship between their respective lengths can have at least the following several possible implementation manners:

[0035] In the first possible implementation manner, the range of the angle between the inclined rod and the cross bar is 120° - 140°.

[0036] In the second possible embodiment, the range of the length of the cross bar is 40 mm - 60 mm.

[0037] In the third possible implementation, the length of the inclined rod ranges from 60 mm to 80 mm.

[0038] In the fourth possible implementation, the length of the cross bar ranges from 40 mm to 60 mm, and the included angle between the inclined rod and the cross bar ranges from 120° to 140°.

[0039] In the fifth possible implementation, the length of the inclined rod ranges from 60 mm to 80 mm, and the included angle between the inclined rod and the cross bar ranges from 120° to 140°.

[0040] In the sixth possible implementation, the length of the cross bar ranges from 40 mm to 60 mm, and the length of the inclined rod ranges from 60 mm to 80 mm.

[0041] In the seventh possible implementation, the length of the cross bar ranges from 40 mm to 60 mm, the length of the inclined rod ranges from 60 mm to 80 mm, and the included angle between the inclined rod and the cross bar ranges from 120° to 140°.

[0042] In the above seven possible implementations, by limiting the value ranges of the lengths of the cross bar and the inclined rod respectively and the value range of the included angle between the two, the operator can hold the inclined rod more conveniently. In addition, in the above seven possible implementations, the length of the cross bar can be 40 mm, 50 mm or 60 mm, or any value between 40 mm and 60 mm, the length of the inclined rod can be 60 mm, 70 mm or 80 mm, or any value between 60 mm and 80 mm, and the included angle between the cross bar and the inclined rod can be 120°, 130° or 140°, or any value between 120° and 140°. The present disclosure does not limit this.

[0043] In the specific implementation provided by the present disclosure, referring to Figure 3 and Figure 4 As shown, an auxiliary convex block 112 for cooperating with the bolt mounting hole 7 of the second turbine return oil pipe is provided on the first surface 11 of the process plug body 1. Here, the auxiliary convex block 112 can be a cylinder whose shape is adapted to the bolt mounting hole 7 of the second turbine return oil pipe. In this way, when installing the process plug for the side oil passage hole of the engine cylinder block, the auxiliary convex block 112 can be inserted into the bolt mounting hole 7 of the second turbine return oil pipe. In this way, through the interaction force between the auxiliary convex block 112 and the bolt mounting hole 7 of the second turbine return oil pipe, the process plug for the side oil passage hole of the engine cylinder block can be reliably held in this position.

[0044] In the specific implementation provided by the present disclosure, referring to Figure 3 andFigure 4 As shown, for the convenience of processing and to increase the overall structural strength, the plugging head 111 can be integrally formed with the process plug body 1.

[0045] In the specific embodiments provided by the present disclosure, with reference to Figure 4 As shown, the process plug for the side oil passage hole of the engine cylinder block further includes a sealing ring 4. The sealing ring 4 is sleeved on the plugging head 111. In this way, when the process plug for the side oil passage hole of the engine cylinder block is installed at the corresponding position on the engine cylinder block 8, the sealing ring 4 sleeved on the plugging head 111 can reliably seal the gap between the plugging head 111 and the side oil passage hole 5 of the engine cylinder block, thereby avoiding the leakage of oil during the cold test process.

[0046] The following describes the usage process of the process plug for the side oil passage hole of the engine cylinder block in conjunction with Figures 1 to 4 :

[0047] When performing a cold test on the engine, first place the process plug for the side oil passage hole of the engine cylinder block at the appropriate position on the engine cylinder block 8, and insert the plugging head 111, the auxiliary convex block 112, and the threaded fastening rod into the side oil passage hole 5 of the engine cylinder block, the second turbine return oil pipe bolt installation hole 7, and the first turbine return oil pipe bolt installation hole 6 respectively. Then, hold the inclined rod with one hand to keep the process plug for the side oil passage hole of the engine cylinder block in this position, and with the other hand, gradually fasten the threaded fastening rod in the first turbine return oil pipe bolt installation hole 6 by operating the operating handle until the stop end face 23 abuts against the first face 11 of the process plug body 1. In this way, under the action of the stop end face 23, the process plug body 1 can press the plugging head 111 tightly in the side oil passage hole 5 of the engine cylinder block. When the cold test is over and the process plug for the side oil passage hole of the engine cylinder block needs to be disassembled, first hold the inclined rod with one hand to keep the process plug for the side oil passage hole of the engine cylinder block in this position, and with the other hand, operate the operating handle to disengage the threaded fastening rod from the first turbine return oil pipe bolt installation hole 6. Then, remove the process plug for the side oil passage hole of the engine cylinder block from the engine cylinder block 8.

However, the present disclosure is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0049] In addition, it should be noted that, in the case of no contradiction, the various specific technical features described in the above specific embodiments can be combined in any suitable way. To avoid unnecessary repetition, the present disclosure will not separately describe various possible combination methods.

[0050] In addition, any combination can be made among various different embodiments of the present disclosure, as long as it does not violate the idea of the present disclosure, and it should equally be regarded as the content disclosed by the present disclosure.
