Problems solved by technology

[0003] Since this method uses a single-wire grinding wheel, the wear of the grinding wheel will affect the profile of the helix. As the grinding process progresses, the wear of the grinding wheel will become more and more serious. surface size, it is necessary to modify the grinding wheel; the process is cumbersome, and it is difficult to guarantee the relative position accuracy between the grinding wheel and the workpiece after the practice is completed

Embodiment Construction

[0017] The multi-line grinding wheel for multi-thread processing proposed by the present invention includes a plurality of grinding blades, the number m of grinding blades is equal to the number n of multi-start threads, and the axial distribution of n grinding blades follows the following rules: L i+1 = L i +(k*m+(i-1) / m)*P 0 , where L i is the distance from the center of the i-th grinding edge to the end face of the grinding wheel, L i+1 is the distance from the center of the i+1th grinding edge to the end face of the grinding wheel, k is a positive integer, P 0 is the pitch of the multi-start thread, 1≤i≤n-1.

[0018] The axial spacing between the grinding edges fully considers the chip removal of grinding metal chips, and its axial spacing conforms to the law of pitch indexing; the use of this multi-thread multi-line grinding wheel can reduce the requirements for indexing and improve Processing accuracy and processing efficiency. Guarantee the accuracy and performanc...

Abstract

The invention relates to a multi-line grinding wheel for multiple threads. The number n of grinding blades of the grinding wheel is equal to the number m of the multiple threads. The molded surfaces of the n grinding blades are consistent. The n grinding blades are distributed in the axial direction according to the following rule: Li+1=Li+(k*m+(i-1) / m)*P0. The multi-line grinding wheel is used for machining the multiple threads, so that the defects that when a single-line grinding wheel is used for machining multiple threads, the requirement for indexing is high, and the machining process is cumbersome are overcome, and the multiple threads can be machined through one-time grinding. The requirements for the grinding feed amount, chip removal and thread pitches are fully considered, distribution of the grinding blades is adjusted through the value of k, and the machining requirements are met.

Description

technical field [0001] The invention relates to a multi-thread grinding wheel with multiple threads, belonging to the field of grinding wheels. Background technique [0002] The planetary roller screw is a typical planetary screw drive, and its transmission contact unit is threaded, while the screw and nut are multi-threaded, generally more than 3. At present, the process of grinding multi-start threads with a single-line grinding wheel is as follows: the grinding wheel is adjusted to the feed rate, and a single helix is ​​ground first; then, the starting position of the second helix is ​​adjusted through the indexing plate to realize the tool setting of the grinding wheel. Grind out the second helix; the 3rd, ..., the nth and so on. [0003] Since this method uses a single-wire grinding wheel, the wear of the grinding wheel will affect the profile of the helix. As the grinding process progresses, the wear of the grinding wheel will become more and more serious. The size o...
