Description

Technical Field

[0001] The invention belongs to the field of cutting technology, and in particular relates to a blank cutting device for ball screw processing. Background Art

[0002] A ball screw is a mechanical transmission component that converts rotational motion into linear motion. The presence of balls makes up for the inevitable screw thread clearance problem in spiral transmission, making the ball screw stable during transmission, with no setbacks or gaps during forward and reverse conversion, low friction resistance, high reversibility and efficiency, which is equivalent to changing the bearing's sliding motion into rolling motion. Therefore, ball screws are widely used in various industrial equipment and precision instruments.

[0024] The present invention has the following beneficial effects:

[0025] When the present invention is used, the lead screw blank is first passed through the clamping rotating mechanism, the outer clamping plate and the inner clamping plate in sequence, and finally passed through the fixed ring until it contacts the grinding head of the No. 2 grinder. At this time, the infrared sensor detects that the lead screw blank is in place and sends a signal to the No. 3 electric telescopic rod and the clamping servo motor. The No. 3 electric telescopic rod is started, and the output end of the No. 3 electric telescopic rod pushes the adjusting rod to drive the rotating ring to rotate, so that the circular clamping plate clamps the lead screw blank, and at the same time, the clamping servo motor drives the clamping screw to rotate, thereby driving the outer clamping plate and the inner clamping plate to clamp the lead screw blank; after the lead screw blank is clamped, the No. 2 grinder, the No. 2 electric telescopic rod, the cutting machine, the No. 1 grinder and the rotating servo motor are turned on at the same time. At this time, the No. 2 grinder grinds one end of the lead screw blank, and at the same time, the No. 2 electric telescopic rod drives the cutting machine to cut the lead screw blank, and the rotating servo motor drives the driving wheel to rotate, and the driving wheel meshes with the teeth, thereby driving the circular ring to rotate, and the circular ring drives the lead screw blank 77 to rotate, thereby improving the cutting efficiency.

[0026] After the cutting is completed, the transfer servo motor is turned on to drive the transfer rod to rotate, so that the fixed ring drives the cut screw blank to rotate to the next grinding work station. The cut end of the cut screw blank contacts the grinding head of the No. 1 grinder to grind it. At the same time, the clamping servo motor is turned on to make its output end rotate in the opposite direction to drive the outer and inner plates to loosen the screw blank to be cut. The conveying servo motor is turned on to drive the conveying screw to rotate, so that the clamping rotating mechanism drives the screw blank to be cut to move to the right, and then the clamping structure of the clamping rotating mechanism loosens the screw blank After returning, the lead screw blank is clamped and transported to the right until the lead screw blank to be cut is transported to the grinding head position of the No. 2 grinder, and then the clamping servo motor is turned on to clamp the outer clamping plate and the inner clamping plate to the lead screw blank to be cut, thereby continuously cutting the lead screw blank. After the grinding is completed, the hydraulic cylinder is turned on to extend its output end to push the lead screw blank out of the fixing ring, and finally it falls into the guide groove and is sent out. The above operation is repeated until the lead screw blank is completely cut. At this time, the cut lead screw blank does not need to be ground, thereby improving the efficiency of lead screw production.

[0027] The present invention starts the adjustment servo motor to drive the adjustment screw to rotate, so that the adjustment slider drives the cutting machine and the No. 1 grinder to move to a suitable position, which is convenient for meeting the needs of different cutting lengths of the lead screw blank. At the same time, the cutting auxiliary table follows the position change of the cutting machine through the auxiliary electric telescopic rod, so that it also moves to the corresponding position to cooperate with the cutting machine, which is convenient for auxiliary positioning and fixing of the lead screw blank during cutting, and avoids deformation of the cutting position of the lead screw blank.

[0061] See also Figure 1-Figure 8As shown, this embodiment is a method for using a blank cutting device for ball screw processing: when in use, first pass the screw blank 77 through the clamping rotating mechanism 6, the outer clamping plate 11 and the inner clamping plate 12 in sequence, and finally pass through the fixing ring 37 until it contacts the grinding head of the second grinder 33. At this time, the infrared sensor 35 detects that the screw blank 77 is in place and sends a signal to the No. 3 electric telescopic rod 73 and the clamping servo motor 14. The No. 3 electric telescopic rod 73 is started, and the output end of the No. 3 electric telescopic rod 73 pushes the adjusting rod 72 to drive the rotating ring 66 to rotate, so that the circular clamping plate 70 clamps the screw blank 77, and at the same time the clamping servo motor 14 drives the clamping screw 8 to rotate, thereby driving the outer clamping plate 11 and the inner clamping plate 12 to clamp the screw blank 77; after the screw blank 77 is clamped, the No. 2 grinder 33, the No. 2 electric telescopic rod 23, the cutter 24, the No. 1 grinder 26 and the rotating servo motor 75 are turned on at the same time. At this time, the No. 2 grinder 33 grinds one end of the screw blank 77, the No. 2 electric telescopic rod 23 drives the cutter 24 to cut the screw blank 77, and the rotating servo motor 75 drives the driving wheel 76 to rotate, and the driving wheel 76 engages with the teeth 63, thereby driving the ring 62 to rotate, and the ring 62 drives the screw blank 77 to rotate, thereby improving the cutting efficiency. After the cutting is completed, the transfer servo motor 31 is turned on to drive the transfer rod 30 to rotate, so that the fixing ring 37 drives the cut screw blank 77 to rotate to the next grinding work position, and the cut end of the cut screw blank 77 contacts the grinding head of the first grinder 26 to grind it. At the same time, the clamping servo motor 14 is turned on to make its output end rotate in the opposite direction to drive the outer clamping plate 11 and the inner clamping plate 12 to loosen the screw blank 77 to be cut, and the conveying servo motor 4 is turned on to drive the conveying screw 3 to rotate, so that the clamping rotating mechanism 6 drives the screw blank 77 to be cut to move to the right, and then the clamping structure of the clamping rotating mechanism 6 loosens the screw blank 7 7 and then returns. After returning, the screw blank 77 is clamped and conveyed to the right until the screw blank 77 to be cut is conveyed to the grinding head position of the second grinder 33, and then the clamping servo motor 14 is turned on to make the outer clamping plate 11 and the inner clamping plate 12 clamp the screw blank 77 to be cut, thereby continuously cutting the screw blank 77. After the grinding is completed, the hydraulic cylinder 28 is turned on to extend its output end to push the screw blank 77 out of the fixing ring 37, and finally fall into the guide groove 27 for delivery. The above operation is repeated until the screw blank 77 is completely cut. At this time, the cut screw blank 77 does not need to be ground, thereby improving the efficiency of screw production.

[0062] It should be further explained that the grinding time of grinder No. 1 26 can be set, as long as the time is less than the cutting time; when it is necessary to cut screw blanks of different lengths, the adjusting servo motor 19 is turned on to drive the adjusting screw 20 to rotate, so that the adjusting slider 21 drives the cutting machine 24 and grinder No. 1 26 to move to the appropriate position. At the same time, the cutting auxiliary table 16 follows the position change of the cutting machine 24, and through the auxiliary electric telescopic rod 15, it also moves to the corresponding position to cooperate with the cutting machine 24.

[0063] When the infrared sensor 35 senses that the screw blank 77 moves to the first grinding position of the No. 2 grinder 33, the infrared sensor 35 first gives the No. 3 electric telescopic rod 73 and the clamping servo motor 14 a signal to turn them on, thereby clamping and fixing the screw blank 77, and then the No. 2 grinder 33 is turned on for grinding; when the cut screw blank 77 rotates to the next grinding position after cutting is completed, the infrared sensor 35 senses that the screw blank 77 is detached, and the No. 2 grinder 33 will be closed, and then the clamping servo motor 14 will be given a signal to release the screw blank 77, and then the conveying servo motor 4 will be given a signal to drive the screw blank 77 to move until it reaches the first grinding position again and is sensed by the infrared sensor 35, and the above process is repeated until the screw blank 77 is completely cut.
