The traction body of the railway passenger car is used as an important component of a bogie of the railway passenger car, and mainly plays a role in transmitting longitudinal tensile or compressive load of a car body. In the rail passenger car traction body machining process, the rail passenger car traction body needs to be clamped and fixed on a numerical control machine operation platform. The traditional rail passenger car traction body fixing mode is as follows: firstly, determining a datum line for a traction body of the railway passenger car and correcting the datum line through manual drawing, then supporting the traction body of the railway passenger car on a numerical control machine tool operating platform by using sizing blocks with equal height, finally fastening bolts on the numerical control machine tool operating platform, and clamping and fixing the traction body of the railway passenger car by a pressing plate connected with the bolts. The traditional rail passenger car traction body positioning and clamping operation is complex, time and labor are wasted, and the machining efficiency is low; and the clamping structure for clamping the rail passenger car traction body by the pressing plate is insecure through the fastening bolt, so that the rail passenger car traction body is not accurately machined, and the product percent of pass is low.
Disclosure of Invention
The utility model provides a positioning tool for processing the traction body of the railway passenger car, which can simplify the positioning and clamping operation of the traction body of the railway passenger car, save time and labor and improve the processing efficiency; and the traction body of the railway passenger car can be firmly clamped, the machining precision of the traction body of the railway passenger car is improved, and the product percent of pass is improved.
The technical solution of the utility model is that:
railway passenger train traction body processing location frock dress, including the bottom plate, its special character lies in: the vertical upward centering chuck is fixedly installed on the top surface of the bottom plate, the inner ends of the jaws of the centering chuck are provided with protruding parts protruding upwards, the vertical first oil cylinders are fixedly installed on the left side and the right side of the centering chuck respectively on the top surface of the bottom plate, the first pressing plate is fixedly installed on the top end of a piston rod of each first oil cylinder, the vertical limiting baffle is fixedly installed on one side of one of the first oil cylinders on the top surface of the bottom plate, and the horizontal second oil cylinder is fixedly installed on one side of the other first oil cylinder on the top surface of the bottom plate.
Further preferably, be located first auxiliary stay body of first clamp plate fixed mounting under the bottom plate top surface, improve rail passenger train traction body location structural stability.
Further preferably, the second auxiliary supporting body is fixedly arranged on one side of the first auxiliary supporting body on the top surface of the bottom plate, so that the stability of the positioning structure of the traction body of the railway passenger car is improved.
Preferably, a vertical third oil cylinder is fixedly arranged on one side of the top surface of the bottom plate, which is positioned on the two first oil cylinders, and a second pressing plate is fixedly arranged at the top end of a piston rod of the third oil cylinder.
The utility model has the advantages that:
because the centering chuck is fixedly arranged on the top surface of the floor and is vertically upward, the inner ends of the claws of the centering chuck are provided with the convex parts which protrude upwards, the rail passenger car traction body is placed on the top surface of the claws of the centering chuck to be horizontally positioned, the convex parts at the inner ends of the claws are propped against the inner wall of the circumference of the central hole of the rail passenger car traction body to be axially positioned, because the convex parts are fixedly arranged on the top surface of the bottom plate and are positioned on one side of a first oil cylinder, a second oil cylinder is fixedly arranged on the top surface of the bottom plate and is positioned on one side of the other first oil cylinder, a piston rod of the second oil cylinder props against the rail passenger car traction body to horizontally and circumferentially rotate by taking the centering chuck as the center until the rail passenger car traction body is propped against the limiting baffle to be circumferentially positioned, because the first oil cylinders which are fixedly arranged on the, start first hydro-cylinder, first clamp plate pushes down the track passenger train and pulls the body fixed, and the track passenger train pulls body location easy operation, and labour saving and time saving has improved machining efficiency to pull the firm clamping of the body with the track passenger train, improved the precision that the body was processed is pull to the track passenger train, improve the product percent of pass.
