railway locomotive pulls pull rod adds clamping apparatus, including the supporting seat, its special character lies in: the rear end of the supporting seat is provided with a rotary table which rotates up and down, the rear end of the rotary table is provided with a driving motor which drives the rotary table to rotate, the rotary table is provided with a fixed clamping block and a movable clamping block which are arranged front and back, opposite surfaces of the fixed clamping block and the movable clamping block are respectively provided with a bayonet, and the two bayonets are perpendicular to each other.
Preferably, the movable clamping block is installed with the rotary table in a left-right sliding mode through a slide way, and a locking screw is installed on the movable clamping block through threads.
Further preferably, a longitudinal pressing plate is arranged between the fixed clamping block and the movable clamping block on the rotary table, so that the firmness of the fixed structure of the traction pull rod is enhanced.
Preferably, one end of the longitudinal pressing plate is hinged with the rotary table, and a locking pull rod is connected between the other end of the longitudinal pressing plate and the rotary table.
Preferably, the lower end of the locking pull rod is hinged with the rotary table, the upper end of the locking pull rod is provided with a nut through threads, and the longitudinal pressing plate is provided with a lateral opening corresponding to the locking pull rod.
Further preferably, the turntable is provided with processing openings corresponding to two ends of the traction pull rod, so that the processing operation of a processing tool bit of the vertical numerical control machine tool is facilitated.
The utility model has the advantages that:
1. the fixed clamping block and the movable clamping block which are arranged in the front-back direction are arranged on the rotary table, the bayonets which are perpendicular to each other are arranged on the opposite surfaces of the fixed clamping block and the movable clamping block, and the two ends of the traction pull rod are quickly clamped through the bayonets of the fixed clamping block and the movable clamping block, so that the clamping operation of the traction pull rod is simplified.
2. The rear end of the supporting seat is provided with the rotary table which rotates up and down, the rear end of the rotary table is provided with the driving motor which drives the rotary table to rotate, the traction pull rod is clamped and fixed behind the rotary table, the rotary table is controlled to rotate through the driving motor, and the two ends of the side end face of the traction pull rod rotating to the top surface are machined once through the machining tool bit of the vertical numerical control machine tool every time the traction pull rod rotates 90 degrees until the four side end faces of the traction pull rod all complete machining operation. The traditional clamping operation of four times is replaced by one-time clamping three-time 90-degree rotation, the clamping time is greatly shortened, and the machining efficiency is improved.
