Description

Technical Field

[0001] This utility model relates to the field of engine disassembly tooling technology, and in particular to an oil pump column disassembly tooling. Background Technology

[0002] like Figure 1 As shown, the existing oil pump string 2 is installed in the mounting channel of the engine housing 1. The mounting channel has openings at both ends. A block is set not far from the opening at one end, and a connecting section is set inside the opening at the other end. The connecting section has internal threads. The oil pump string is tightly fitted into the mounting channel by interference fit.

[0003] When disassembling existing engines, because there is no dedicated tooling for disassembling oil pump strings, it is impossible to remove the oil pump strings intact. The oil pump strings can only be removed by damaging them, resulting in the oil pump strings not being effectively reused and causing waste. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model designs a tooling for disassembling an oil pump tubing column.

[0005] The present invention adopts the following technical solution:

[0006] An oil pump string disassembly tool includes a vibrating bar and a disassembly head detachably connected to the vibrating bar. The disassembly head includes a guide cylinder and a telescopic rod. One end of the guide cylinder is provided with an external thread that is threadedly fixed to a connecting section of the mounting channel of the engine housing. The telescopic rod cooperates with the guide cylinder to extend and retract axially along the inner axis of the guide cylinder. One end of the telescopic rod is connected to a screw, and a top cover is threadedly connected to the screw. The outer diameter of the top cover is larger than the inner diameter of the oil pump string, and the inner diameter of the guide cylinder is larger than the outer diameter of the oil pump string. The other end of the telescopic rod is fixedly connected to a connector, and the tail end of the connector is detachably connected to the vibrating bar.

[0007] Preferably, the connector has an internal threaded hole at both ends, which is used to connect to the vibrator rod via the internal threaded hole.

[0008] Preferably, the vibrating rod includes a vibrating rod, a vibrating hammer, and a limiting nut. The vibrating rod is a screw rod with the limiting nut threaded onto it, and the vibrating hammer is sleeved on the vibrating rod. The limiting nut allows the user to adjust the vibration distance.

[0009] Preferably, the vibrating rod has a handheld end attached to its tail end.

[0010] Preferably, the guide cylinder is fixedly connected to an external hexagonal screw nut at its tail end. This facilitates the threaded connection between the guide cylinder and the mounting channel of the engine housing.

[0011] The beneficial effects of this utility model are: This utility model designs an oil pump string disassembly tool, which presses the oil pump string from the other end by the top cover, and removes the oil pump string step by step by the vibration force of the hammer. It can remove the oil pump string without damage, realize the reuse of the oil pump string, and has high disassembly efficiency. Attached Figure Description

[0017] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:

[0018] Example: Figure 2-3 As shown, an oil pump column disassembly fixture includes a vibrating rod and a disassembly head detachably connected to the vibrating rod. The disassembly head includes a guide cylinder 4 and a telescopic rod 5. One end of the guide cylinder is provided with an external thread that is threadedly fixed to a connecting section of the mounting channel of the engine housing. The telescopic rod cooperates with the guide cylinder to extend and retract axially along the inner axis of the guide cylinder. One end of the telescopic rod is connected to a screw rod 6, and a top cover 7 is threadedly connected to the screw rod. The outer diameter of the top cover is larger than the inner diameter of the oil pump column, and the inner diameter of the guide cylinder is larger than the outer diameter of the oil pump column. The other end of the telescopic rod is fixedly connected to a connector 8, and the tail end of the connector is detachably connected to a vibrating rod 9.

[0019] The connector has internal threaded holes at both ends, which are threaded to the vibrating rod. The vibrating rod includes a vibrating rod 10, a vibrating hammer 11, and a limiting nut 12. The vibrating rod is a screw rod with the limiting nut threaded onto it, and the vibrating hammer is sleeved on the vibrating rod.

[0020] A handheld end is installed at the tail end of the vibrating rod. An external hexagonal screw nut is fixedly connected to the tail end of the guide cylinder.

[0021] like Figure 4As shown, when using this oil pump string disassembly fixture, first, the guide cylinder is threadedly connected to the connecting section of the engine housing's mounting channel via external threads. Then, a telescopic rod is inserted into the guide cylinder, pushing out from the front end of the oil pump string. The top cover is then inserted through another opening in the mounting channel and threadedly connected to the screw at the end of the telescopic rod. A vibratory bar is then threaded onto the connector at the tail end of the telescopic rod. Holding the guide cylinder in one hand and a vibratory hammer in the other, the oil pump string is gradually disassembled after repeated vibrations and taps. This method allows for the non-destructive removal of the oil pump string, enabling its reuse, and offers high disassembly efficiency.

[0022] The embodiments described above are merely preferred solutions of this utility model and are not intended to limit this utility model in any way. Other variations and modifications are possible without departing from the technical solutions described in the claims.
