Embodiment Construction

[0021] like figure 1 , figure 2 As shown, the device for processing multi-thread threads of the present invention includes a main shaft 13 sleeved with a tubular workpiece 16. There is a shaft shoulder 15 on the main shaft 13. The tubular workpiece 16 is sleeved on the main shaft 13 and is offset against the shaft shoulder 15. The side away from the shaft shoulder 15 locks the tubular workpiece 16 with a first nut 23; it also includes a rotating device, which includes an active friction plate 11, a sleeve 10, a transverse gear 9, a transverse rack 8, a first vertical Gear 7, the second vertical gear 3, the rotating shaft 5 and the vertical rack 2, the horizontal rack 8 is "L" type, and the two ends of the "L" have horizontal teeth 22 and vertical teeth 21 respectively, the first vertical tooth Both the gear 7 and the second vertical gear 3 are sleeved on the rotating shaft 5, and both ends of the first vertical gear 7 and the second vertical gear 3 are locked with the second...

Abstract

The invention discloses a device for machining multi-start threads. The device comprises a rotary device, a feeding device and a spindle; a tubular workpiece and a transverse bearing sleeve the spindle; the rotary device comprises a driving friction sheet, a sleeve, a transverse gear, a transverse rack, a first vertical gear, a second vertical gear, a rotary shaft and a vertical rack; the transverse rack is L-shaped; teeth are arranged at two end surfaces of the L shape; a tool rest is arranged on the feeding device; the vertical rack is connected with the feeding device. The device overcomes the technical defects that the existing device for machining the multi-start threads is complex in structure and complicated in operation and wastes resource, and the device for machining the multi-start threads is simple in structure, simple in operation and resource-saving.

Description

technical field [0001] The invention belongs to the field of mechanical processing, and in particular relates to a device for processing multi-thread threads. Background technique [0002] A multi-thread thread refers to a thread formed along two or more helical lines on a cylinder, and the multi-thread threads are equidistantly distributed in the axial direction. Due to the large thread lead angle of the multi-thread thread, the friction formed by screw or nut screwing is small, so the multi-thread thread is usually used to transmit power and motion, such as jacks for lifting equipment maintenance, for clamping workpieces Bench vices for fitter processing, etc. [0003] When processing threads, it is necessary to give the tool a feed force to move the tool forward, and at the same time to give the workpiece a rotational force to rotate the workpiece to process the thread. At present, the devices for processing multi-thread threads usually include the feeding device of the...
