Abstract

The invention relates to a deflagration type inner and outer ring drawing detacher. A sliding block cylinder barrel flexibly slides on a guide rail and is connected with a valve seat through a tension spring. And the piston is fixed on the valve seat and is matched with the sliding block cylinder barrel. A fuel oil plunger pump and a lubricating oil plunger pump are installed on the valve seat, and when the two plunger pumps are impacted and compressed by the sliding block cylinder barrel, fuel oil and lubricating oil can be sprayed into the sliding block cylinder barrel and the piston ring groove respectively. The sliding block cylinder barrel is rapidly sleeved with the piston under the tension effect of the tension spring, air in the sliding block cylinder barrel is compressed, the temperature rises sharply, fuel oil pumped into the sliding block cylinder barrel is mixed with high-temperature compressed air, detonation is rapidly conducted, the size expands sharply, and strong impact thrust is generated to separate the sliding block cylinder barrel from the piston. And the separated sliding block cylinder barrel continuously rushes to the piston under the action of the tension spring, the process is repeated, the piston is regularly subjected to counteractive impact thrust, and the counteractive impact thrust is transmitted to the drag hook through the guide rail to generate regular impact drawing force, so that the embedded workpiece is disassembled.

Description

Technical Field

[0001] The invention relates to a deflagration type inner and outer ring puller and disassembler, which is used for disassembling various inlaid workpieces, especially for disassembling difficult-to-disassemble workpieces in the field without power supply. Background Art

[0002] At present, when disassembling various embedded workpieces, such as bearings, flywheels, sleeves and other workpieces, manual spiral pullers or hydraulic pullers are generally used. However, there must be a force vertex on the workpiece, and the workpiece is disassembled by using the static pulling force generated by the reaction force. For the disassembly of inner ring workpieces without a force vertex on the workpiece, currently only a sliding hammer puller can be used, which relies on manual continuous sliding of the hammer head to utilize the impact force of the hammer head for disassembly, which is not only time-consuming and labor-intensive, but also difficult to disassemble larger inner ring workpieces. Summary of the invention

[0003] In order to solve the existing problem of disassembling workpieces without force-bearing vertices in the market as described in the background technology, the present invention provides a deflagration type inner and outer ring pulling and disassembling device.

[0004] The solution adopted by the present invention to solve the technical problem is: the hook 1 is hinged on the hook plate 2, the hook plate 2 is fixed on the end of the guide rail 3, and the valve seat 9 is fixed on the guide rail 3 and keeps a certain distance from the hook plate 2. The slider cylinder 4 is passed through the guide rail 3 and can slide flexibly on the guide rail 3, and is connected to the valve seat 9 by a tension spring 5. The piston 6 is fixed on the valve seat 9 and is coaxially matched with the slider cylinder 4, so that the slider cylinder 4 can be tightly sleeved on the piston 6 and flexibly reciprocate. In order to ensure the air tightness between the piston 6 and the slider cylinder 4, two piston rings are installed on the piston 6. A through hole is vertically opened in the middle of the piston 6, which is connected to the fuel duct in the valve seat 9. A ring groove is processed in the middle of the piston 6, which is connected to the lubricating oil duct inside the piston 6 and also to the lubricating oil duct in the valve seat 9. A fuel plunger pump 7 and a lubricating oil plunger pump 8 are installed on the valve seat 9, and their oil discharge ports are respectively connected to the fuel duct and the lubricating oil duct in the valve seat 9. A fuel tank 11 is fixed at the rear end of the valve seat 9. The fuel tank 11 has two mutually isolated inner chambers. One inner chamber stores fuel and communicates with the fuel inlet of the fuel plunger pump 7 through a pipeline. A valve is installed on it. The other inner chamber stores lubricating oil and communicates with the oil inlet of the lubricating oil plunger pump 8 through a pipeline. A handle 10 is installed at the end of the valve seat 9 and the guide rail 3 for the convenience of the operator to hold it. When in use, first fill the fuel tank 11 with fuel and lubricating oil, including but not limited to diesel, hook the workpiece to be disassembled with the hook 1, open the valve on the fuel pipeline, manually pull the slider cylinder 4 a certain distance and then release it, the slider cylinder 4 is quickly inserted into the piston 6 under the tension of the tension spring 5, the air in the slider cylinder 4 is rapidly compressed and the temperature rises sharply, as the slider cylinder 4 continues to move, the fuel plunger pump 7 and the lubricating oil plunger pump 8 are impacted and compressed by the slider cylinder 4, and the fuel and lubricating oil are pumped into the slider cylinder 4 and the ring groove of the piston 6 through the channel respectively, the fuel pumped into the slider cylinder 4 is mixed with the high-temperature compressed air and reaches the ignition point of the fuel, and the volume expands rapidly, generating a strong impact thrust to separate the slider cylinder 4 and the piston 6 and discharge the exhaust gas after combustion. The lubricating oil pumped into the ring groove on the piston 6 lubricates the slider cylinder 4 and the piston 6 to prevent wear of both. After the slider cylinder 4 is separated from the piston 6, it is pulled by the tension spring 5 and then rushes toward the piston 6. During this process, the slider cylinder 4 is refilled with air until the piston 6 is inserted and the aforementioned fuel work process is repeated and circulated. Due to the inertia of the slider cylinder 4, the piston 6 is subjected to a reaction impact thrust each time the slider cylinder 4 is separated from the slider cylinder 4, and is transmitted to the hook 1 through the guide rail 3, thereby generating a regular impact pulling force, thereby removing the embedded workpiece. After closing the valve on the fuel pipeline, there is no fuel work, and the slider cylinder 4 can gradually stop.

[0005] The beneficial effects of the present invention are: it can generate regular impact pulling force, disassemble difficult-to-disassemble inlaid workpieces without force vertices, and is suitable for use under no-power supply conditions. BRIEF DESCRIPTION OF THE DRAWINGS
