Part splitting device and part splitting method for crankshaft connecting gear of high pressure water pump

Abstract

The invention discloses a simple part splitting device for a crankshaft connecting gear of a high pressure water pump. The simple part splitting device comprises a structural part frame and a baking gun, wherein the structural part frame comprises two rectangular supporting steel plates, a bolt hole is formed in each of four corners of each supporting steel plate, and upper, middle and lower I steel slots are separately formed from top to bottom symmetrical to a vertical center line in the middle of each supporting steel plate; two supporting steel plates are vertically and parallelly arrangedin a spaced manner, are connected and fixed separately at four corners by arranging connecting screws and matching with nuts, and upper, middle and lower I steel matched with the slots is inserted into the corresponding upper, middle and lower I steel slots of the two supporting steel plates; and a bottom plate is fixedly arranged above the two pieces of lower I beam and a jacking device is arranged in the center of the bottom plate. By applying the simple part splitting device, a part of the crankshaft connecting gear on the high pressure water pump can be taken out quickly, and the labor intensity of workers is reduced, the labor efficiency is improved and the repair cost is lowered.

Description

technical field [0001] The invention belongs to the technical field of high-pressure water pump equipment for rolling high-speed wheels, and in particular relates to a simple dismantling device and method for parts of a high-pressure water pump crankshaft connecting a gear. Background technique [0002] Masteel Wheel Co., Ltd. is an important train wheel production base in my country. It is the largest wheel manufacturer in Asia and the only domestic company capable of producing passenger car wheels with speeds above 120Km / h. The research and development of heavy-duty wheels has reached the international advanced level. At present, there are two wheel production lines with an annual production capacity of 800,000 pieces. The key part is the high-pressure pump room. There are 12 high-pressure water pumps dedicated to the second-line rolling system of wheels. The delivery pressure is 32 MPa, and they are placed in two rows on the ground. The large crankshaft is the main core d...

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that the large crankshaft shaft and the gear are connected and assembled by heating the shaft gear through oil temperature and installed with the pin shaft in the above background technology. It is difficult to replace and disassemble through the traditional removal method, and propose a high-pressure The simple disassembly device and disassembly method of the parts connected to the crankshaft on the water pump and the disassembly method are implemented, and the process is verified. The application of the present invention not only quickly removes the parts of the crankshaft connected to the gear on the high-pressure water pump, but also reduces the labor intensity of workers and improves labor efficiency. Reduce the maintenance cost, meanwhile, the dismantling device described in the present invention basically does not require large investment, takes up little space, is convenient to use and maintain, and the relevant size parameters and performance indicators of the crankshaft reassembled to connect the gear can meet the original design requirements, which is reasonable Group production provides a guarantee
