[0026] The working principle of a processing device for the spatial guide vane of a cryogenic ethylene pump disclosed in the present invention is as follows: Control the top displacement drive motor 130. The output shaft of the top displacement drive motor 130 drives the top displacement bidirectional lead screw 132 to rotate. The rotation of the top displacement bidirectional lead screw 132 drives the two three-jaw chuck brackets 135 to move relative to each other (away from or close to each other, and at the same time, the three-jaw chuck brackets 135 will also slide on the top displacement spline shaft 133), so as to adjust the distance between the two three-jaw chucks 139. The two three-jaw chucks 139 fix the guide vane to be turned. Control the top rotation drive motor 131. The output shaft of the top rotation drive motor 131 drives the top displacement spline shaft 133 to rotate. The top displacement spline shaft 133 drives the spline belt pulley 136 to rotate. The spline belt pulley 136 drives the rotation transmission belt 137 to rotate. The rotation transmission belt 137 drives the three-jaw chuck 139 to rotate. The three-jaw chuck 139 will drive the guide vane to be turned to rotate, so as to realize turning at different positions (since the outer contour of the guide vane is not circular, it is necessary to cooperate with the continuous telescoping of the telescopic rods of the central support electric cylinder 103 and the edge adjustment electric cylinder 102 to control the distance between the guide vane and the tool 111). Control the middle displacement drive motor 129. The output shaft of the middle displacement drive motor 129 drives the middle displacement lead screw 127 to rotate. The two middle displacement lead screws 127 rotate synchronously through the middle displacement lead screw 127. The rotation of the two middle displacement lead screws 127 will drive the top displacement support side plate 128 to move, so as to drive the guide vane to displace axially along the middle displacement lead screw 127, realizing cutting at different positions (such as a processed flat section). Control the telescopic rod of the bottom displacement drive electric cylinder 124. The telescopic rod of the bottom displacement drive electric cylinder 124 drives the bottom displacement bracket 122 to move on the bottom displacement slide bar 121 through the drive cross beam 123. The bottom displacement bracket 122 drives the middle displacement support side plate 125 to move. At this time, the guide vane can be driven to move synchronously for turning along the axis of the guide vane.
[0027] For example, if the outer contour of the guide vane is an irregular curved surface, it is necessary to adjust the angle with the tool 111. At this time, controlling the telescopic amount of the telescopic rods of the edge adjustment electric cylinders 102 at different positions can control the swing angle of the disc plate 104 (the central support electric cylinder 103 does not move, Figure 2 、 Figure 3 the middle part of the disc plate 104 in the figure is in a hollow state, which is convenient for the discharge of iron filings), so as to control the swing of the guide vane on the disc plate 104. Cooperating with the movement of the guide vane, an irregular curved surface can be processed (the feeding needs to control the synchronous telescoping of all the edge adjustment electric cylinders 102 and the central support electric cylinder 103).
[0028] The rotation of the cutting tool 111 needs to be achieved by controlling the cutting motor 113 and the control motor 114. Specifically, when the cutting motor 113 starts, the control motor 114 also needs to start. The output shaft of the cutting motor 113 drives the inner gear 119 to rotate. The inner gear 119 drives the ring gear disk 118 to rotate through the planetary gears 117. The ring gear disk 118 drives the driving spindle 108 to rotate. The driving spindle 108 drives the cutting tool 111 to rotate through the spline camshaft 109 (to replace different cutting tools 111, only need to pull the cutting tool 111 away from the driving spindle 108, and then insert the new cutting tool 111 and the spline camshaft 109 onto the driving spindle 108). In order to reduce the deformation of the cutting tool 111 during cutting, at this time, the internal reinforcement sleeve 110 is pulled out from the external reinforcement sleeve 107 and sleeved on the cutting tool 111 to achieve the effect of strengthening the cutting tool 111 (where the internal reinforcement sleeve 110 is replaced synchronously with the change of the rod diameter of the cutting tool 111). The output shaft of the control motor 114 drives the planetary gear driving disk 115 to rotate through the adjustment belt 116. The rotation of the planetary gear driving disk 115 drives all the planetary gears 117 to revolve. At this time, the control motor 114 can control the revolution speed and direction of the planetary gears 117. Therefore, when the rotational speed of the output shaft of the cutting motor 113 remains unchanged, the transmission ratio between the output shaft of the cutting motor 113 and the driving spindle 108 can be controlled. Therefore, the function of jointly driving the cutting tool 111 to rotate by the cutting motor 113 and the control motor 114 can be achieved, and it also has the function of stepless speed regulation.
