Problems solved by technology
At present, the disassembly process mainly uses the disassembly method of pulling out the positioning pin according to the inertia generated by the gravity block. The disassembly efficiency is low and the labor intensity is high. Workers who operate for a long time may easily cause physical exhaustion.
At present, other tools used for positioning pin disassembly take a long time to disassemble, and do not make full use of the more common air compression equipment in the factory. The cost of the tool is high, it is relatively heavy, and it is difficult to be used in actual production

The invention discloses a pneumatic-hydraulic pin puller. The pneumatic-hydraulic pin puller comprises a support as well as a pneumatic device, a crank-slider mechanism and a hydraulic device which are mounted on the support, wherein the pneumatic device is connected with the hydraulic device through the crank-slider mechanism, and comprises a pneumatic wind wheel, an air delivery pipe and a rotating shaft; the two ends of the rotating shaft are mounted on the support, the middle part of the rotating shaft is of a spline structure, the rotating shaft penetrates through a matched spline groove in the pneumatic wind wheel, and then the pneumatic wind wheel is fixed on the support; one end of the air delivery pipe is connected with the pneumatic wind wheel; the other end of the air delivery pipe is connected with the air input end of air compression equipment; the crank-slider mechanism is connected with the rotating shaft and used for transferring power supplied by the pneumatic device to the hydraulic device; and the hydraulic device is used for dismounting of a positioning pin. According to the pneumatic-hydraulic pin puller disclosed by the invention, the conventional air compression equipment in a factory is sufficiently utilized for supplying power to the pneumatic-hydraulic pin puller, wind energy is converted into kinetic energy, and then the power is transferred through the crank-slider mechanism to the hydraulic device for pulling-out of the positioning pin, thereby saving manpower and achieving simple and convenient operation.
Description
technical field [0001] The invention belongs to the technical field of mechanical assembly, and in particular relates to a pneumatic hydraulic pin puller. Background technique [0002] At present, for the stamping die manufacturing industry and fixture manufacturing industry, a large number of positioning pins are required in the manufacturing process of molds and fixtures, and all installed positioning pins need to be pulled out during repeated debugging of molds and disassembly of fixtures. The fit of the pin adopts an interference fit, so there is greater difficulty in the disassembly process of the positioning pin. The disassembly process is currently mainly based on the use of gravity blocks to generate inertia to pull out the positioning pin. The disassembly efficiency is low and the labor intensity is high. Workers who operate for a long time may easily cause physical exhaustion. At present, other tools used for positioning pin disassembly take a long time to disasse...
