Description

Technical Field

[0001] The utility model relates to the technical field of diesel engines, in particular to an auxiliary tool for disassembling a distribution plate of a diesel engine starting air distributor. Background Art

[0002] The starting air distributor is used to control the air intake timing of the starting valves of each cylinder of the diesel engine, so as to control the ignition sequence of the diesel engine. It is an important part of the diesel engine. The starting air distributor is driven by the shaft system, the driving end is connected to the diesel engine gear system, the shaft at the output end is conical, and the distribution plate is pressed into the conical output end.

[0003] The prior art generally uses a puller to disassemble the distribution plate. However, since the distribution plate of the starter air distributor is made of aluminum and is installed on the conical shaft at the output end, when the ordinary disassembly process uses a puller for disassembly, firstly, the puller will crush the end surface of the distribution plate, and secondly, the puller size is generally large, and it is difficult to find a suitable puller for disassembly. Therefore, there is a problem of difficulty in disassembling the distribution plate. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an auxiliary tool for disassembling a distribution plate of a diesel engine starting air distributor.

[0005] The utility model adopts the following technical solutions:

[0006] Construct a diesel engine starting air distributor distribution plate disassembly auxiliary tooling, comprising:

[0007] A bearing plate, formed with a push hole and at least one connecting hole;

[0008] A pushing member for pushing the output shaft of the air distributor to start the air distributor, wherein the pushing member is movably arranged in the pushing hole; and

[0009] At least one connecting member is detachably arranged in the mounting hole of the distribution plate of the starting air distributor, and the connecting member is arranged in the connecting hole.

[0010] In some embodiments, the supporting plate is rectangular.

[0011] In some embodiments, chamfers are provided on the rectangular corners of the carrying plate.

[0012] In some embodiments, the size of the carrier plate is smaller than the opening size of the distribution tray.

[0013] In some embodiments, the number of the connecting holes is two, which are symmetrically arranged on both sides of the push hole.

[0014] In some embodiments, the connecting member is a bolt, and the connecting member is detachably inserted into the connecting hole and the mounting hole on the distribution plate, and the mounting hole is a threaded hole.

[0015] In some embodiments, the connecting hole is a threaded hole.

[0016] In some embodiments, the pushing member is a pushing bolt, and the pushing hole is a threaded hole.

[0017] In some embodiments, a protrusion is provided at the end of the push member close to the output shaft.

[0018] In some embodiments, the end of the output shaft is provided with a groove corresponding to the protrusion.

[0019] The utility model has the following advantages:

[0020] The utility model provides a connecting piece corresponding to the installation hole of the distribution plate and a pushing piece corresponding to the output shaft of the starting air distributor, so that the constructed auxiliary tooling for disassembling the distribution plate of the diesel engine starting air distributor corresponds to the size structure of the starting air distributor, thereby solving the problem that the puller size is generally large and it is difficult to find a suitable puller for disassembly;

[0021] The present application realizes connection with the distributor by setting a connecting piece. During the disassembly operation, the connecting piece is inserted into the mounting hole at the bottom of the distribution plate, so the force on the distribution plate is not easy to cause deformation of the distribution plate, thus solving the problem that the puller will crush the end surface of the distribution plate when the puller is used for disassembly;

[0022] The present application provides a push piece, so that the process of disassembling the distribution plate is changed from using a puller to pull out the easily deformed distribution plate in the prior art to using a push piece to push the output shaft with greater rigidity, which can make the disassembly of the distribution plate easier.

[0028] In the following description, specific details such as specific system structures and technologies are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present invention. However, it should be clear to those skilled in the art that the present invention can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details that hinder the description of the present invention.

[0029] Figure 1 and Figure 2 An auxiliary tool 1 for disassembling a distribution plate of a diesel engine starting air distributor in an embodiment of the utility model is shown, which can adapt to the size and material of the distribution plate of the diesel engine starting air distributor to avoid damage to the distribution plate during the disassembly process.

[0030] like Figure 2 As shown, the starting air distributor 3 includes a main body and a distribution plate 2 detachably arranged on the main body, and an output shaft 301 is arranged on the main body, and the output shaft 301 is a tapered shaft. A groove-shaped opening 203 is formed at the end of the distribution plate 2 away from the main body, and a through assembly hole 201 and a mounting hole 202 are formed at the bottom end of the opening 203 along the thickness direction of the bottom wall, wherein the assembly hole 201 is a tapered hole, and the output shaft 301 is penetrated in the assembly hole 201. There are two mounting holes 202, which are respectively located on both sides of the assembly hole 201.

[0031] The diesel engine starting air distributor distribution plate disassembly auxiliary tool 1 includes a bearing plate 10, a push piece 20 and at least one connecting piece 30. The bearing plate 10 is used to bear the stress during the disassembly process and serves as a mounting plate for the push piece 20 and the connecting piece 30. It is formed with a push hole 11 and at least one connecting hole 12 along the thickness direction. The push piece 20 is movably inserted into the push hole 11 and is used to push the output shaft 301 of the starting air distributor 3. The connecting piece 30 is inserted into the connecting hole 12 and can be detachably inserted into the mounting hole 202 to achieve detachable connection with the distribution plate 2.

[0032] The setting of the auxiliary tooling 1 for disassembling the distribution plate of the diesel engine starting air distributor makes it possible to disassemble the distribution plate 2 by only inserting the connecting member 30 into the connecting hole 12 and the mounting hole 202 at the same time, so as to realize the installation on the distribution plate 2, and make the pushing member 20 abut against the output shaft 301. At this time, the pushing member 20 and the connecting member 30 are connected to form a whole through the bearing plate 10. At the same time, since the connecting member 30 is installed on the distribution plate 2, the pushing member 20 and the distribution plate 2 are in a relatively fixed state at this time. However, since the pushing member 20 is movably inserted into the pushing hole 11 and abuts against the output shaft 301, at this time, by moving the pushing member 20, it is moved in the pushing hole 11, that is, the output shaft 301 is pushed, and then the output shaft 301 is realized to fall off from the assembly hole 201 of the distribution plate 2, that is, the distribution plate 2 is disassembled from the main body of the starting air distributor 3.

[0033] Since the diesel engine starting air distributor distribution plate disassembly auxiliary tool 1 constructed in the present application corresponds to the size structure of the starting air distributor 3, the problem that the puller size is generally large and it is difficult to find a suitable puller for disassembly is solved. At the same time, since the connecting member 30 of the present application is inserted into the mounting hole 202 at the bottom of the distribution plate 2 during the disassembly operation, the force on the distribution plate 2 is not easy to cause the distribution plate 2 to deform, and the problem that the puller will crush the end surface of the distribution plate 2 when using the puller for disassembly is solved.

[0034] like Figure 1 As shown, in some embodiments, the supporting plate 10 is arranged in a rectangular shape.

[0035] In this embodiment, the rectangular size of the carrier plate 10 is slightly smaller than the opening size of the opening 203 of the distribution plate 2. This can prevent the edge of the carrier plate 10 from abutting against the end of the distribution plate 2 away from the main body of the starting air distributor 3 during the pushing process, thereby preventing the end of the distribution plate 2 from being deformed.

[0036] In some other optional embodiments, the shape of the carrier plate 10 can also be set to other shapes such as circular, elliptical, polygonal, irregular, etc. It should be understood that the setting of its shape only needs to ensure that the pushing member 20 and the connecting member 30 can be penetrated, and the structural rigidity constructed by its shape can ensure that no deformation occurs during the pushing process.

[0037] In some other optional embodiments, the size of the carrier plate 10 may be equal to or greater than the size of the opening 203 of the distribution tray 2. It should be understood that when the size of the carrier plate 10 is equal to or greater than the size of the opening 203, the length of the connecting member 30 and the pushing member 20 should be set to ensure that the carrier plate 10 is always spaced apart from the distribution tray 2 during the pushing and disassembly process, so as to avoid the carrier plate 10 and the end of the distribution tray 2 abutting against each other, causing deformation of the end of the distribution tray 2.

[0038] like Figure 1 As shown, in some embodiments, the four corners of the rectangular shape of the carrier plate 10 are chamfered respectively to prevent the distribution plate 2 from being scratched by the sharp corners during assembly or use.

[0039] It should be understood that the chamfer on the carrier plate 10 can be an oblique angle or a rounded angle, etc., which is not specifically limited here.

[0040] In some embodiments, the number of the connecting holes 12 may also be set to two, which respectively correspond to the two mounting holes 202 and are symmetrically arranged on both sides of the push hole 11 .

[0041] It should be understood that “respectively corresponding to the two mounting holes 202 ” refers to the positional relationship between the two connecting holes 12 and the push hole 11 , corresponding to the positional relationship between the assembly hole 201 on the distribution plate 2 and the two mounting holes 202 .

[0042] Specifically, the axes of the two connecting holes 12 and the axis of the pushing hole 11 are located on the same plane, and the distances between the two connecting holes 12 and the pushing hole 11 are equal.

[0043] In this embodiment, the axis of the long axis of the carrying plate 10 passes through the plane where the axes of the two connecting holes 12 and the axis of the pushing hole 11 are located, and the axis of the short axis is perpendicular to the plane.

[0044] In some other optional embodiments, when the number of the connecting member 30 is only one, it can be set correspondingly to one of the two mounting holes 202, and one corresponding connecting hole 12. In this case, the size of the carrying plate 10 can be reduced accordingly.

[0045] In some embodiments, the connector 30 is a bolt, and the size of the bolt head is larger than the diameter of the connecting hole 12. The connector 30 is detachably inserted into the connecting hole 12, and the mounting hole 202 is a threaded hole. During the installation process, the connector 30 is inserted into the connecting hole 12 and the mounting hole 202 at the same time, and is threadedly connected to the mounting hole 202, thereby achieving the connection between the connector 30 and the distribution plate 2.

[0046] Specifically, in this embodiment, the connection hole 12 is also a threaded hole, and the connection piece 30 is threadedly connected to the carrier plate 10 and the distribution plate 2 to improve the stability of the connection.

[0047] In some other optional embodiments, the connecting hole 12 can also be set as a smooth hole. According to the relative movement direction between the supporting plate 10, the connecting member 30 and the distribution plate 2 during the pushing and disassembly process, when the connecting hole 12 is set as a smooth hole, it is only necessary to ensure that the bolt head of the connecting member 30 rests against the end of the connecting hole 12 away from the distribution plate 2, that is, a close fit between the two can be achieved during the pushing and disassembly process without relative movement.

[0048] In some other optional embodiments, the connecting member 30 may also be disposed on the bearing plate 10, cannot be removed from the connecting hole 12, and can only be detachably connected to the mounting hole 202. For example, the bolt head of the connecting member 30 is fixed to the bearing plate 10.

[0049] In some other optional embodiments, the connecting member 30 may also be configured as only a threaded rod or a screw rod, etc., and its end is fixed to the supporting plate 10 to achieve the connection between the two.

[0050] In some embodiments, the push member 20 is a push bolt, and its push hole 11 is a threaded hole. In the process of push disassembly, only the push member 20 needs to be screwed to achieve the movement of the push member 20 in the push hole 11, and then the output shaft 301 can be pushed.

[0051] In some other optional embodiments, the pushing member 20 can also be configured as a lead screw.

[0052] For example Figure 2As shown, in some embodiments, the push member 20 includes a body 21 and a protrusion 22 disposed at the end of the body 21, and the body 21 is a push bolt. The protrusion 22 is disposed at the end of the body 21 close to the output shaft 301, and is provided with the protrusion 22, which is used to contact the end of the output shaft 301 during the pushing process, so as to avoid direct contact between the end of the push member 20 and the end of the output shaft 301, which would cause scratches to the output shaft 301 when the plane is slightly tilted.

[0053] In this embodiment, the protrusion 22 is hemispherical, coaxially disposed with the body 21 , and has a diameter smaller than that of the body 21 .

[0054] In some other optional embodiments, the diameter of the protrusion 22 may be equal to the diameter of the body 21 , that is, the end of the body 21 may be directly configured as a hemispherical shape with an equal diameter.

[0055] In some other optional embodiments, the protrusion 22 may not be provided, and the output shaft 301 may be protected by providing a soft elastic gasket such as rubber at the end of the body 21.

[0056] Furthermore, in some embodiments, a groove is correspondingly provided at the end of the output shaft 301, thereby realizing a positioning function during the docking process, avoiding incomplete correspondence between the two during docking, or during the pushing process, the pushing member 20 is separated from the end of the output shaft 301 during rotation, thereby causing damage to the output shaft 301 or even the distribution disk 2.

[0057] In some embodiments, the diameter of the push hole 11 is larger than the diameter of the connecting hole 12, and the diameter of the push member 20 is larger than the diameter of the connecting member 30. This ensures that the push member 20 can withstand a larger torque during the push process, ensuring the stability of the operation.

[0058] The present application will be further described below through a specific embodiment:

[0059] In this embodiment, the bearing plate 10 is 63 mm long, 30 mm wide, and 10 mm thick. The four corners of the rectangle are provided with chamfers with an inclination of 45° and a length of 5 mm. The connecting hole 12 is a circular threaded hole of φ10, and the distance between the two connecting holes 12 is 44 mm. The push hole 11 is an M16 threaded hole, and the distance between it and the two connecting holes 12 is 22 mm respectively.

[0060] It can be understood that the above embodiments only express the preferred implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the utility model. It should be pointed out that, for ordinary technicians in this field, without departing from the concept of the utility model, the above-mentioned technical features can be freely combined, and several deformations and improvements can be made, which all belong to the protection scope of the utility model. Therefore, all equivalent changes and modifications made to the scope of the claims of the utility model should fall within the scope of the claims of the utility model.
