The utility model provides a worm processing centering adjustment device, which can flexibly adjust the position of the positioning sleeve according to the centering requirements during worm processing to ensure the smooth feeding process of the worm;

[0003] However, it cannot adapt to different sizes of worm blanks, and cannot automatically slide left and right to adjust the amount of engagement with the thread rolling cutter. Utility Model Content

[0004] The technical problem to be solved by the utility model is: in order to overcome the above problems, a worm processing centering adjustment device is provided, which solves the above problems.

[0005] The utility model solves the technical problem by adopting the following technical solutions:

[0006] A worm processing centering adjustment device includes a thread rolling machine for processing worm threads, wherein the thread rolling machine includes two worm thread rolling machine cutters arranged symmetrically and in parallel, and also includes a self-adjusting symmetrical guide rail arranged on the thread rolling machine and a transverse sliding block arranged on the self-adjusting symmetrical guide rail for transverse sliding sliding, a longitudinal sliding rail is fixedly arranged between the two transverse sliding blocks, two longitudinal sliding blocks are symmetrically arranged on the longitudinal sliding rail for sliding back and forth, and a clamping arm is fixedly arranged on the longitudinal sliding block.

[0007] Preferably, a top seat is fixedly provided at the upper end of the clamp arm, a top is rotatably provided in the top seat, and blind holes for the top of the top are provided at both ends of the worm blank, so that the worm is rotatably supported between the two top seats.

[0008] Preferably, the height of the rotating shaft of the top is consistent with the height of the rotating shaft of the hob of the worm thread rolling machine.

[0009] Preferably, a tightening screw is threadedly connected between the clamp arms, and a cross slot is provided at the end of the tightening screw for adjustment by a cross screwdriver. The tightening screw and the two clamp arms have opposite screwing directions. When the tightening screw is rotated, the clamp arms will move closer to or away from each other, thereby adjusting screw blanks of different lengths.

[0010] Preferably, the self-adjusting symmetrical guide rail is fixed to the thread rolling machine by bolts.

[0011] Preferably, the clamping arm and the longitudinal sliding block are fixed by screws.

[0012] The advantages and positive effects of the utility model are: compared with the existing centering clamping structure, it is simpler and more convenient to use, and can clamp blanks of different specifications;

[0013] When the two worm rolling cutters on the thread rolling machine are started, they will approach each other to perform thread rolling on the worm blank. The sliding cooperation of the transverse slider on the self-adjusting symmetrical guide rail ensures that the worm blank can always be at the same bite depth with the two worm rolling cutters. The other two tips can quickly clamp worm blanks of different lengths, which is simple, convenient and efficient. BRIEF DESCRIPTION OF THE DRAWINGS
