Description
Technical Field
The utility model relates to a train draw beam processing equipment especially relates to a vertical numerical control lathe clamping frock of train draw beam.
Background
The draft sill is an important bearing part on a bogie and is a main stress part for connecting a middle beam of a train, and the draft sill needs to be clamped and fixed in the process of machining a bearing hole of the draft sill, so that the form and position tolerance of the bearing hole of the draft sill is strictly controlled. The traditional equipment for machining the bearing hole of the draw beam is a lathe, the draw beam needs to be marked by marking, the marking is used for alignment, and then the draw beam is clamped by a four-jaw chuck of the lathe. The positioning and clamping traction beam is slow, time-consuming and labor-consuming in operation and low in machining efficiency.
Disclosure of Invention
The utility model relates to a solve above-mentioned technical problem, provide a vertical numerical control lathe clamping frock of train draw beam, it can fix a position and clamping draw beam fast, and operation labour saving and time saving improves machining efficiency.
The technical solution of the utility model is that:
train draw beam vertical numerically controlled lathe clamping frock, including the base, its special character lies in: the center of the base is provided with three vertical supporting rods which are circumferentially arranged around the circle center of the base, the outer edge of the base is provided with two supporting seats which are radially arranged, one of the supporting seats is fixedly provided with a V-shaped fixed clamping block, the other supporting seat is provided with a V-shaped movable clamping block in a radial sliding manner through a slide way, the V-shaped fixed clamping block and the V-shaped movable clamping block are radially arranged oppositely, and a radial adjusting mechanism is arranged between the V-shaped movable clamping block and the supporting seat where the V-shaped movable clamping block is located.
Further preferably, the vertical support rod is a vertical screw rod which is installed with the base through threads, the heights of the three vertical screw rods are adjusted through the threads, and the levelness of the plane where the top ends of the three vertical screw rods are located is determined.
Preferably, the radial adjusting mechanism is an adjusting bolt radially installed on the supporting seat through threads, and the inner end of the adjusting bolt is rotatably installed with the V-shaped movable clamping block.
Preferably, the outer end of the V-shaped movable clamping block is provided with a radial insertion hole, and the inner end of the adjusting bolt is inserted into the radial insertion hole.
Further preferably, two vertical limiting rods which are radially and symmetrically arranged are arranged on the base and abut against the protruding part on the outer edge of the train traction beam, so that the train traction beam is prevented from rotating in the circumferential direction in the machining process.
The utility model has the advantages that:
the top ends of the three vertical support rods arranged in the center of the base form a horizontal support surface, so that the top ends of the three vertical support rods are horizontally placed on the traction beam, and the traction beam is ensured to keep a vertical posture; the V-shaped fixed clamping block is fixedly arranged on one of the two supporting seats arranged on the outer edge of the base, the V-shaped movable clamping block is radially and slidably arranged on the other supporting seat through the slide way, the radial adjusting mechanism is adjusted to move the V-shaped movable clamping block to the V-shaped fixed clamping block, the V-shaped movable clamping block and the V-shaped fixed clamping block rapidly clamp the draw beam, the draw beam and the base are coaxially positioned, finally, the bearing hole of the draw beam is machined through the machining tool bit which is coaxial with the base on the numerical control lathe, the draw beam positioning and clamping operation are rapid, the operation is time-saving and labor-saving, and the machining efficiency of the bearing hole of the draw beam is improved.
