Description

Technical Field

[0001] The present application relates to the technical field of diesel engines, and particularly relates to a disassembly tool for adjusting the explosion pressure of a diesel engine. Background Art

[0002] In a diesel engine, a fuel injection pump injects fuel into a cylinder in a high-pressure manner within a short time to achieve the mixing and combustion of fuel and air. The magnitude of the fuel injection advance angle has a great influence on the operation of the diesel engine. If the fuel injection advance angle is too large, it will lead to a long combustion period, too high an explosion pressure, and rough operation of the diesel engine. If the fuel injection advance angle is too small, it will lead to combustion lag, too low an explosion pressure, and low working efficiency of the diesel engine. However, due to the cumulative errors in the machining and assembly of parts in the diesel engine, the actual explosion pressure of the diesel engine will be outside the theoretical range.

[0003] Therefore, the user needs to replace and adjust the thickness of the shim of the push rod in the diesel engine to adjust the fuel injection advance angle, and then adjust the explosion pressure of the diesel engine. However, due to the special installation position of the push rod in the diesel engine, it is difficult to manually disassemble it, and there is currently no disassembly tool that is easy to operate and labor-saving to disassemble the push rod.

Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0027] Combined with the attached Figure 1 and the attached Figure 2 , the present application relates to a disassembly tool for adjusting the explosion pressure of a diesel engine. The disassembly tool includes a first pull head 1100, a first pull rod 1200, a stop block 1300, and a top head 1400. The lower end of the first pull head 1100 is used to connect the top column of the diesel engine. The lower end of the first pull rod 1200 is fixedly connected to the first pull head 1100. The stop block 1300 is arranged on the first pull rod 1200. The top head 1400 is sleeved on the outer side of the first pull rod 1200, and the stop block 1300 is located above the top head 1400. On the first pull rod 1200, the top head 1400 is located between the stop block 1300 and the first pull head 1100.

[0028] Further, the stop block 1300 is arranged at the top of the first pull rod 1200, and the top head 1400 can move up and down along the first pull rod 1200. The user moves the top head 1400 upward and impacts the stop block 1300. The top head 1400 impacts the stop block 1300 by inertia, and the stop block 1300 drives the first pull rod 1200 to move upward. Then, the first pull rod 1200 lifts the top column through the first pull head 1100, realizing the disassembly of the top column so as to replace or adjust the gasket of the top column.

[0029] It can be understood that, in order to increase the inertia of the top head 1400, the top head 1400 is set as a solid metal structure.

[0030] As an implementation manner, the lower end of the first slider 1100 is sleeved on the outer side surface of the top column. A first connection hole is provided at the lower end of the first slider 1100. The top column penetrates through the first connection hole, and the top end of the top column is fixed to the first connection hole.

[0031] Specifically, the disassembly tooling includes at least two first locking clips 1500. The first locking clips 1500 are arranged on the inner side wall of the first connection hole to reduce the aperture of the first connection hole. The first locking clips 1500 are clamped around the outer side wall of the top column. The lower end of the first pull rod 1200 abuts against the top end of the top column, so that the top column is fixed to the lower end of the first slider 1100.

[0032] In some examples, two first locking clips 1500 are provided. The two first locking clips 1500 are arranged in a split manner to form a semi-circular structure. The two first locking clips 1500 are clamped around the outer side wall of the top column. It can be understood that in other examples, if at least three first locking clips 1500 are provided, each first locking clip 1500 is combined to form a circular ring structure that is clamped around the outer side wall of the top column.

[0033] It should be noted that the top end of the top column is formed into a tapered shape that is larger at the top and smaller at the bottom. The aperture of the first connection hole is larger than the maximum diameter of the top end of the top column, so that the top end of the top column can penetrate through the first connection hole. When the first slider 1100 fills the first connection hole with the first locking clips 1500 between the inner side wall of the first connection hole and the outer side wall of the top column, and the lower end of the first pull rod 1200 abuts against the top end of the top column, the first locking clips 1500 are clamped around the tapered outer side wall of the top column, thereby preventing the top column from separating from the first slider 1100. And the lower end of the first pull rod 1200 applies a downward pressure to the top end of the top column, so that the top end of the top column is fixedly connected to the first slider 1100.

[0034] It can be understood that one side of the first locking clip 1500 facing the outer side wall of the top column is provided as a tapered side wall, so that the side wall shape of the first locking clip 1500 is adapted to the tapered shape of the top end of the top column.

[0035] Furthermore, the first connection hole is provided as a tapered hole that is larger at the top and smaller at the bottom, so as to prevent the first locking clips 1500 from falling downward under the pressure from the outer side wall of the top column when the first pull rod 1200 presses down the top column.

[0036] In some examples, the first locking clips 1500 are arranged in a circle along the inner side wall of the first connection hole. The first locking clips 1500 are combined to form a ring structure, so that the outer side wall of the top column is uniformly stressed, and the strength of the fixed connection between the top column and the first slider 1100 is improved. Or, as an alternative solution, at least it can also be designed as: the first locking clips 1500 are arranged at intervals on the inner side wall of the first connection hole.

[0037] In some examples, the first locking clip 1500 is made of a rubber material, and there is a flexible contact between the first locking clip 1500 and the top post to avoid damaging the surface of the top post.

[0038] As an implementation, the first pull rod 1200 is threadedly connected to the first pull head 1100. When the user rotates the first pull rod 1200, the first pull rod 1200 can move downward so that the lower end of the first pull rod 1200 abuts against the top of the top post.

[0039] Specifically, the lower end of the first pull rod 1200 is provided with an external thread, the upper end of the first pull head 1100 is provided with a threaded hole, and the lower end of the first pull rod 1200 penetrates through the threaded hole.

[0040] In some examples, the first pull rod 1200 is set as a stud.

[0041] As an implementation, the first pull head 1100 includes a first lower connection part 1102 and a first upper connection part 1101. The threaded hole for connecting the first pull rod 1200 is arranged on the first upper connection part 1101, and the first connection hole is arranged on the first lower connection part 1102.

[0042] The left and right ends of the first upper connection part 1101 are respectively connected to the first lower connection part 1102. The middle part of the first upper connection part 1101 is hollowed out to form a U-shaped shape with the opening downward. The port at the upper end of the first connection hole is in the hollowed-out area of the first upper connection part 1101, so that the user can put the first locking clip 1500 into the first connection hole from the hollowed-out area.

[0043] As an implementation, an impact part 1401 is arranged at the top of the top head 1400, and the impact part 1401 is formed in a circular shape.

[0044] Furthermore, the diameter of the impact part 1401 is larger than the diameter of the top head 1400 to increase the contact area between the impact part 1401 and the stop block 1300, thereby increasing the impact force of the impact part 1401 on the stop block 1300.

[0045] As an implementation, the stop block 1300 is sleeved on the outside of the first pull rod 1200. Furthermore, the stop block 1300 is threadedly connected to the first pull rod 1200.

[0046] It should be noted that there are also the following replaceable embodiments for the disassembly tooling.

[0047] Combined with the attached Figure 3 and the attached Figure 4, the disassembly tooling includes a second pull head 2100, a second pull rod 2200, and a support base 2300. The lower end of the second pull head 2100 is used to connect to the top column of the diesel engine. The lower end of the second pull rod 2200 is fixedly connected to the second pull head 2100, and the second pull rod 2200 passes through the support base 2300. The support base 2300 serves as the support for the second pull rod 2200 to lift the top column. Under the operation of the user, the second pull rod 2200 moves upward on the support base 2300 in a screw drive manner, and the second pull rod 2200 lifts the second pull head 2100, thereby lifting the top column to achieve the disassembly of the top column for replacing or adjusting the gasket of the top column.

[0048] Specifically, the support base 2300 is provided with a through hole, and the second pull rod 2200 passes through the through hole of the support base 2300. Further, a nut is provided on the support base 2300. The second pull rod 2200 passes through the nut and is threadedly connected to the nut. The nut is fixed on the support base 2300. When the user rotates the second pull rod 2200, the second pull rod 2200 can move upward.

[0049] It can be understood that when the user operates the top end of the second pull rod 2200 with a tool, the second pull rod 2200 can be rotated. In some examples, the second pull rod 2200 is set as a stud or a shoulder bolt.

[0050] Regarding the second pull rod 2200 and the support base 2300, as an alternative solution, it can be at least designed as: the through hole of the support base 2300 is set as a threaded hole, and the second pull rod 2200 is threadedly connected to the support base 2300.

[0051] As an implementation manner, the lower end of the second pull head 2100 is sleeved on the outer side wall of the top column. The lower end of the second pull head 2100 is provided with a second connection hole. The top column passes through the second connection hole, and the top end of the top column is fixed to the second connection hole.

[0052] Specifically, the disassembly tooling includes at least two second lock clips 2400. The second lock clips 2400 are arranged on the inner side wall of the second connection hole to reduce the aperture of the second connection hole. When the second pull rod 2200 lifts the second pull head 2100, the second lock clips 2400 are clamped on the outer side wall of the top column so that the second pull head 2100 can lift the top column.

[0053] In some examples, two first lock clips 1500 are provided. The two first lock clips 1500 are arranged in a split manner to form a semi-circular structure, and the two first lock clips 1500 are clamped on the outer side wall of the top column. It can be understood that in other examples, if at least three first lock clips 1500 are provided, each first lock clip 1500 is combined to form a ring structure that is clamped on the outer side wall of the top column.

[0054] It should be noted that the aperture of the second connection hole is larger than the maximum diameter of the top end of the ejector pin, so that the top end of the ejector pin can penetrate through the second connection hole. The second pull head 2100 is filled with the second locking clip 2400 between the inner side wall of the second connection hole and the outer side wall of the ejector pin at the second connection hole. When the second pull rod 2200 lifts the second pull head 2100, the second locking clip 2400 clamps onto the tapered outer side wall of the ejector pin, thereby preventing the ejector pin from separating from the second pull head 2100.

[0055] It can be understood that one side of the second locking clip 2400 facing the outer side wall of the ejector pin is set as a tapered side wall, so that the side wall shape of the second locking clip 2400 is adapted to the tapered shape of the top end of the ejector pin.

[0056] Furthermore, the second connection hole is set as a tapered hole with a larger upper part and a smaller lower part to prevent the second locking clip 2400 from falling downward from the second connection hole when the top end of the ejector pin presses down the second locking clip 2400.

[0057] In some examples, the second locking clips 2400 are arranged in a circle along the inner side wall of the second connection hole, and the second locking clips 2400 are combined to form an annular structure, so that the outer side wall of the ejector pin is uniformly stressed, and the strength of the fixed connection between the ejector pin and the second pull head 2100 is improved. Or, as an alternative solution, it can be at least designed as: the second locking clips 2400 are arranged at intervals on the inner side wall of the second connection hole.

[0058] In some examples, the second locking clip 2400 is made of rubber material, and the second locking clip 2400 has a flexible contact with the ejector pin to avoid damaging the surface of the ejector pin.

[0059] As an implementation manner, the second pull head 2100 includes a second upper connection portion 2101 and a second lower connection portion 2102. The lower end of the second pull rod 2200 is connected to the second upper connection portion 2101, and the second connection hole is arranged in the second lower connection portion 2102.

[0060] The left and right ends of the second upper connection portion 2101 are respectively connected to the second lower connection portion 2102. The middle part of the second upper connection portion 2101 is hollowed out to form a U-shaped shape with an opening downward. The port at the upper end of the second connection hole is located in the hollowed-out area of the second upper connection portion 2101, so that the user can put the second locking clip 2400 into the second connection hole from the hollowed-out area.

[0061] As an implementation manner, the disassembly tooling includes a sleeve 2500. The second pull head 2100 is arranged in the sleeve 2500. The support seat 2300 is arranged at the top end of the sleeve 2500. The top end of the second pull rod 2200 extends out from the top end of the sleeve 2500. The lower end of the sleeve 2500 abuts against the structure of the diesel engine. The support seat 2300 and the sleeve 2500 provide support for the upward movement of the second pull rod 2200.

[0062] Further, the side wall of the sleeve 2500 is provided with a window so that the user can put the second lock clip 2400 into the second connection hole from the window.

[0063] The embodiments of the present application have been described in detail with reference to the accompanying drawings. However, the present application is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present application within the knowledge of those of ordinary skill in the art.
