Problems solved by technology
The disadvantages of this raceway sectional processing method are: due to the large contact area of the grinding wheel during grinding, the surface of the raceway is thermally deformed during grinding, resulting in the machining accuracy of the product cannot meet the requirements; and the surface of the grinding wheel is worn during normal use. Soon, life expectancy also decreases

Embodiment Construction
[0016] A method for machining a screw raceway by a waterjet, the method is specifically as follows:
[0017] 1) Move the water jet linearly along the axis of the screw; what is the pressure of the water jet? ? ;
[0018] 2) While the water jet moves linearly along the axis of the screw, the screw rotates, and the rotation of the screw matches the linear motion of the water jet. The axis of the water jet outlet and the helix of the screw Tangent, that is, the deflection angle of the water jet is the same as the helix angle of the lead screw; the sectional shape of the water jet is the same as that of the screw raceway; the raceway of the lead screw that meets the requirements is processed.
[0019] figure 2 It is a schematic diagram of the direct motion relationship between the water jet and the lead screw in the present invention. The water outlet 12 of the water knife 11 is adapted to the section shape of the raceway 14 of the leading screw 13 . When the final...

The invention discloses a method for processing a lead screw roller path by using a water jet cutter. The water jet cutter does rectilinear motion in the axial direction of a lead screw, simultaneously, the lead screw does rotary motion, the rotary motion of the lead screw is matched with the rectilinear motion of the water jet cutter, the axis of a water outlet of the water jet cutter is tangent to the spiral line of the lead screw, the section of the water outlet of the water jet cutter is identical to that of the lead screw roller path, and accordingly the lead screw roller path meeting requirements can be processed. The ultrahigh pressure water jet cutter is adopted to process the lead screw roller path, thermal deformation does not happen in the processing process, product processing accuracy is high, grinding wheels are not used, and accordingly the method is environment-friendly and energy-saving.
Description
technical field [0001] The invention relates to a processing method for a lead screw raceway, in particular to a method for processing a lead screw raceway with an ultra-high pressure water jet. Background technique [0002] Now the raceway section of the ground ball screw is ground by grinding wheel, see figure 1 , in the figure, grinding wheel 1, raceway 2. The grinding surface of the used emery wheel 1 has the same shape as the surface of the raceway 2, and it is formed once when grinding. The disadvantages of this raceway sectional processing method are: due to the large contact area of the grinding wheel during grinding, the surface of the raceway is thermally deformed during grinding, resulting in the machining accuracy of the product cannot meet the requirements; and the surface of the grinding wheel is worn during normal use. Soon, lifespan also declines. Contents of the invention [0003] In order to overcome the problems existing in the prior art, the object...
