Title: SHAFT THREAD MACHINING LIMITING CLAMP OF THREAD ROLLING MACHINE
Abstract:
A shaft thread machining limiting clamp of a thread rolling machine, comprising a base frame, a limiting block (5), a movable positioning plate (1), a hinge pin (6), a spring I, a baffle (9), a bolt (12), and guide rods (11); the base frame comprises a side plate I (14), a side plate II (2), and a connecting plate (8); the limiting block (5) is of a plate structure; a V-shaped opening is formed in one side of the limiting block (5); a positioning slot is formed in the other side of the limiting block (5); the movable positioning plate (1) has an L-shaped plate structure, and one end of the movable positioning plate (1) is provided in a horizontal open slot (4) formed in the side plate I (14) and is rotatably connected with the horizontal open slot (4); one end of the spring I is provided on the lower part of the other side of the limiting block (5), and the other end of the spring I is provided on the lower part of the connecting plate (8); one end of each of at least two guide rods (11) is separately provided on the baffle (9), and the other end of each of at least two guide rods (11) is separately inserted in guide holes which are matched with the guide rods (11) and are respectively formed in the side plate I (14) and the side plate II (2); the bolt (12) is inserted in a screw hole formed in the lower part of the baffle (9); and one end of the bolt is rotatably connected with the connecting plate (8). By means of the clamp, the accuracy of a long shaft at the radial position can be guaranteed, and therefore, the precision of thread machining is guaranteed.
