Referring to fig. 1, the invention provides a flexible universal device for machining a center sill slave plate seat hole of a railway wagon, which comprises a workbench 1, a portal frame 2, a small sliding table 3, two spindle boxes 4 which are arranged on the left side and the right side of the portal frame 1 and can move up and down and left and right, a top pressing device 5, a workpiece moving roller bed 6, a numerical control system 7 and the like. The portal frame 2 is arranged on the workbench 1, the workbench 1 is also provided with a workpiece moving roller way 6, a servo motor, a speed reducer, a lead screw, a lubricating system and the like, the lead screw is a ball screw pair, and the portal frame 2 is driven by the servo motor and the ball screw pair to move longitudinally along the workbench 1. Two small sliding tables 3, a guide rail, a servo motor, a reducer, a screw rod, a lubricating system and the like are symmetrically arranged on the upright columns on two sides of the portal frame 2 in a left-right mode, and two spindle boxes 4 are respectively arranged on the small sliding tables 3 corresponding to the spindle boxes and can move back and forth along the small sliding tables 3 under the driving of the servo motor, the reducer and a ball screw pair. The small sliding table 3 can move up and down along the upright post of the portal frame 2, so that the spindle box 4 can move up and down along the upright post of the portal frame 2. Therefore, the main spindle box 4 can move up and down and left and right under the drive of the servo motor and the ball screw pair. The main spindle box 4 in the embodiment is provided with 27 holes, 27 drill bits are installed, the arrangement of the drill bits is consistent with the positions of the front and the rear of the center sill workpiece 8 of the main type railway wagon C70E and the plate seat holes, and the 27 holes of the slave plate seat of the center sill workpiece 8 of the main type railway wagon C70E can be drilled at one time. The top pressing device 5 is arranged in the middle position below a cross beam of the portal frame 2 and consists of an oil cylinder, a piston rod and a pressing head, and when a middle beam workpiece 8 reaches a preset position through the workpiece moving roller bed 6, the piston rod is driven by a hydraulic system to move until the pressing head presses the middle beam workpiece 8. The workpiece moving roller bed 6 is used for conveying a middle beam workpiece 8 to a designated position, and the numerical control system 7 is used for driving each servo motor and controlling the actions of the hydraulic and detection systems.
When the holes of the plate seat of the middle beam of the railway wagon are machined, the device can realize the simultaneous machining of multiple holes; when the transverse position of the center sill from the plate seat hole changes due to the change of the type of the railway wagon, only one row of longitudinal drill bits of the main spindle box 4 needs to be reserved, the rest drill bits are removed, and the main spindle box 4 is transversely moved in a numerical control mode, so that all holes are machined; when the wagon type changes and leads to the horizontal position and the longitudinal position of well roof beam from the plate seat hole all to change, headstock 4 only remains a drill bit, and all the other drill bits are all got off, then realize the processing in hole with numerical control's mode, and concrete work flow is as follows:
the first work flow is as follows: the center sill workpiece 8 moves to the right position through the workpiece moving roller way 6 → the portal frame 2 moves to the working position and is positioned → the top hold-down device 5 holds down the center sill workpiece 8 → the spindle box 4 moves quickly to approach the slave plate seat → the drill of the spindle box 4 rotates → the spindle box 4 continues to move to the slave plate seat to finish drilling → the spindle box 4 returns → the drill stops rotating. The process is suitable for mass production of C70E and similar center sills, and the number and the position of the drill bits of the main headstock 4 are completely matched with the number and the position of the plate seat holes of the center sill.
The second work flow is as follows: the middle beam workpiece 8 moves in place through the workpiece moving roller way 6 → the portal frame 2 moves to a working position and is positioned → the top hold-down device 5 compresses the middle beam workpiece 8 → the spindle box 4 moves quickly to approach the slave plate seat → the drill of the spindle box 4 rotates → the spindle box 4 continues to move to the slave plate seat to finish the drilling of the first longitudinal three holes → the spindle box 4 returns → the moving portal frame 2 moves to the position of the second row of longitudinal holes to perform the drilling of the second row of holes → the above actions are repeated until all the holes are machined. The process is suitable for medium-batch production, the longitudinal hole distance of the slave plate seat is consistent with the hole distance of the slave plate seat of the beam slave plate seat in the existing batch production, the transverse distance is inconsistent, only one row of longitudinal drill bits of the spindle box 4 needs to be reserved before use, and other drill bits are removed.
The third workflow is: the middle beam workpiece 8 moves in place through the workpiece moving roller way 6 → the portal frame 2 moves to a working position and is positioned → the top hold-down device 5 holds down the middle beam workpiece 8 → the spindle box 4 moves quickly to approach the slave plate seat → the drill of the spindle box 4 rotates → the spindle box 4 continues to move to the slave plate seat to finish the drilling of the first hole → the portal frame 2 and the spindle box 4 are moved simultaneously through the numerical control system 7 until the drill reaches the position of the second hole → the above actions are repeated until the whole holes are machined. The process is suitable for small-batch production, the situation that the longitudinal hole distance and the transverse hole distance of the slave plate seat are different from those of the slave plate seat hole of the beam in the existing large-batch production is that only one drill bit of the spindle box 4 needs to be reserved before use, and other drill bits are removed.
