Problems solved by technology
[0009] Due to structural limitations, the mechanical parts driven by the servo motor connected with the screw cannot move horizontally X1-X1 along the existing driven shaft, vertically move Y1-Y1 along the existing driven shaft, and move Z1 axially along the existing driven shaft -Z1 has a large range of motion in three directions, especially it cannot meet the movement amount of the existing driven shaft in the axial direction of Z1-Z1, and it cannot meet the gapless meshing of any number of grinding points on the tooth surface , Each grinding point must be found by the gear grinding technician bit by bit to find the backlash value, so that it cannot be guaranteed that each grinding point has the same backlash value, which is not only inefficient, but also has a complicated mechanical structure and is inconvenient to adjust. And it affects the grinding effect

The invention discloses a device with same backlash for grinding points of numerical control spiral bevel gear lapping machine and a control method thereof. The device comprises a drive shaft, a drive spiral bevel gear, a driven shaft, a driven spiral bevel gear, a device for pushing the driven spiral bevel gear to move along the axial direction thereof, and a device for pushing the drive spiral bevel gear to move along the axial direction thereof. The control method includes the steps of inputting processing parameters in a man-computer interface, generating codes, judging whether the codes are generated for the first time; if yes, beginning backlash detection, moving to a first grinding point to measure backlash difference between the first grinding point and the position of a standard installation distance, moving to a second grinding point to measure backlash difference between the second grinding point and the position of the standard installation distance, moving to a third grinding point to measure backlash difference between the third grinding point and the position of the standard installation distance, beginning to grind, and finishing grinding. The invention has the advantages that the defect of trying to find the grinding points in prior art is overcome, the same backlash value among all the grinding points is ensured, the contact area is improved and the grinding effect and efficiency are improved.
Description
technical field [0001] The invention relates to a numerical control spiral bevel gear grinding machine, in particular to a method for having the same side clearance at multiple grinding points on the numerical control spiral bevel gear grinding machine. Background technique [0002] When grinding the contact area of a pair of spiral bevel gears meshing with each other on the CNC spiral bevel gear grinding machine, it is necessary to determine the coordinate values of each grinding point on the gear grinding machine, especially the backlash value, which must be experienced It is set by the gear grinding technician, and every time the gear grinding technician gives the coordinate value Y1 of the tooth height direction of the grinding point and the coordinate value X1 of the tooth length direction of the grinding point, he must give a backlash value Z1, when the tooth height of the grinding point When the direction coordinate value Y1 and the grinding point tooth length dir...
