Technical Field
The utility model relates to a draw beam on the railway vehicle bogie especially relates to a railway vehicle draw beam processing location frock.
Background
The railway passenger car traction beam is an important component of a railway passenger car bogie. In the process of machining the track passenger car traction beam, the track passenger car traction beam needs to be machined. The traditional railway passenger train draw beam's locate mode is: 1. manually marking a line on the traction beam of the railway vehicle to determine a datum line, 2, supporting the traction beam of the railway vehicle on a processing platform through a plurality of groups of sizing blocks, and 3, fixing the traction beam of the railway vehicle on the processing platform through a bolt fastening pressing plate. The traditional positioning mode has the defects of complicated positioning process, low machining efficiency, insecure positioning structure, easy occurrence of machining size deviation due to displacement of the traction beam of the railway passenger car and low product forming rate.

The utility model relates to a solve above-mentioned technical problem, provide a railway vehicle draw beam processing location frock, it can simplify the location process, improves machining efficiency, and location structure is firm, prevents the railway vehicle draw beam displacement, improves the product shaping rate.
The technical solution of the utility model is that:
railway vehicle draw beam processing location frock, including the bottom plate, its special character lies in: four columns are arranged on the top surface of the bottom plate in a circumferential direction, centering plates are respectively arranged at the top ends of the four columns, inclined planes are respectively arranged on the outer sides of the four centering plates, the four inclined planes are located on the same conical surface, two positioning columns which are symmetrically arranged in a radial direction are arranged on the outer sides of the four columns on the top surface of the bottom plate, and a pressing plate which moves up and down is arranged above the positioning columns.
Preferably, a lifting plate moving up and down is installed above the bottom plate, and the four upright posts are installed on the top surface of the lifting plate to adjust the height of the lifting plate and further adjust the height of the centering plate.
Preferably, the lifting plate is provided with two guide holes which are radially and symmetrically arranged, the bottom plate is provided with two guide rods which are radially and symmetrically arranged, and the guide rods penetrate through the corresponding guide holes to prevent the lifting plate from rotating circumferentially.
Preferably, a support frame is arranged on the top surface of the lifting plate, a vertically downward ejector rod is arranged on the top surface of the support frame through threads, the lower end of the ejector rod abuts against the top surface of the guide rod, and the height of the lifting plate is adjusted through the ejector rod.
Preferably, the centering plates are hinged with the upright columns, and the lower ends of the four centering plates are connected with a connecting plate, so that the four centering plates synchronously rotate, and the arc surface at the lower end of the draw beam of the railway passenger car is adaptively attached to the inclined surface of the centering plate.
Preferably, a vertical screw is arranged on the top surface of the positioning column, the pressing plate is sleeved on the screw, a nut is arranged at the top end of the screw, and a supporting column used for supporting the outer end of the pressing plate is arranged on the bottom surface of the bottom plate and located on the outer side of the positioning column.
The utility model has the advantages that:
the lower end circular arc surface of the traction beam of the railway passenger car is in self-adaptive fit with the inclined surfaces of the four centering plates for concentric positioning; because install two reference columns that are located four stand outsides and radial symmetrical arrangement at the bottom plate top surface, reciprocate and install the clamp plate in the reference column top, push down the clamp plate, the clamp plate is fixed with the centre gripping of railway vehicle draw beam, has simplified the location process, has improved machining efficiency, and location structure is firm, effectively prevents the displacement of railway vehicle draw beam, has improved the product shaping rate.
