[0011] Preferably, the transmission groove includes two arc-shaped grooves and two vertical grooves, the arc-shaped grooves and the vertical grooves surround the outer wall of the rotating cylinder, and the arc-shaped grooves and the vertical grooves are connected.

[0012] Preferably, the method for using the automatic feeding device for grinding the outer circle of a worm shaft comprises the following steps:

[0013] S1: The worm is placed on a clamping device in a placement cavity in a carrier tube, and the worm in one of the placement cavities is located below the grinding device. After the grinding device grinds the worm, the driving motor drives the driving rod to rotate, and the rotation of the driving rod drives the driving frame to rotate. The intermittent rod on the driving frame contacts the intermittent groove on the intermittent rotating disk, and the intermittent rotating disk can be intermittently rotated 90 degrees under the drive of the intermittent rod. The rotation of the intermittent rotating disk drives the rotating rod to rotate, and the rotating rod drives the driving gear to rotate. The driving gear drives the annular gear ring to rotate the carrier tube 90 degrees, thereby moving the next group of worms to be ground to the bottom of the grinding device;

[0014] When the worm is pushed into the placement cavity corresponding to the loading device, the moving frame, driven by the pressure spring, makes the moving wheel contact the inclined surface on the annular plate. At this time, the movement of the moving frame will drive the clamping frame to move, and the movement of the clamping frame drives the moving chuck to slide on the outer wall of the rotating sleeve. When the moving chuck moves, the moving chuck drives the hinged frame to make the clamping plate slide in the rotating sleeve. At this time, the two clamping plates are in an outward expansion state, and then when the feeding device moves the worm toward the placement cavity, the two clamping plates set will not cause obstruction to the worm. When the bearing tube rotates to drive the worm to deflect in the direction of the grinding device, the moving wheel will move to the plane with the inclined surface on the annular plate. At this time, when the moving frame moves and drives the clamping frame to move, the clamping frame will make the moving chuck drive the two clamping plates to clamp the worm, so that when the worm moves to the grinding device, the worm is in a clamping state;

[0015] S3: When the bearing tube drives the worm to deflect toward the grinding device, under the influence of the one-way shaft, the bearing tube rotates, and the adjusting gear on the adjusting rod rotates synchronously with the transmission gear, and the adjusting gear will not rotate under the influence of the transmission gear. When the worm moves to the grinding device, the abutment rod provided on the outer wall of the positioning rod will contact the raised end of the convex plate, and the positioning rod will move toward the direction of the adjusting rod under the drive of the convex plate. When the positioning rod moves in the slide groove, it will drive the adjusting frame to move toward the direction of the adjusting rod. At this time, the adjusting frame drives the telescopic end of the rotating sleeve When the adjusting rod is moved toward the adjusting rod, the inner wall of the rotating sleeve will dock with the slot on the adjusting rod. At this time, the one-way shaft is driven to rotate by the rotating motor, and the one-way shaft drives the transmission gear to rotate. The rotation of the transmission gear drives several adjusting gears to rotate synchronously, and only the rotating sleeve where the adjusting piece contacts the convex plate is in a docking state with the corresponding adjusting rod, and thus can only drive the rotating sleeve at the grinding device to rotate. The worm in the rotating sleeve is in a clamping state at this time, and thus the clamped worm can be rotated to cooperate with the grinding device to perform a rotational grinding operation on the outer wall of the worm;

[0016] S4: When the rotating rod rotates continuously, the rotating rod will drive the spur gear to rotate, and the rotation of the spur gear will drive the rotating ring gear to rotate. The rotation of the rotating ring gear will cause the rotating cylinder to rotate on the support frame. Driven by the reset spring, the clamping rod is at one end of the vertical slot. As the rotating cylinder rotates, the rotating cylinder will cause the clamping rod to move toward the arc slot, and then the clamping rod drives the two connecting rods to move the loading push plate away from the placement cavity. At this time, the worm can be placed on the support frame from the discharge port on the support frame. As the rotating rod continues to rotate, when the placement cavity on the bearing cylinder corresponds to the loading push plate, the clamping rod will move to the vertical slot, and then driven by the reset spring, the worm placed on the support frame can be quickly pushed from the loading push plate to the placement cavity.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] In the present invention, the intermittent rod can make the intermittent rotating disk intermittently rotate 90 degrees. The rotation of the intermittent rotating disk will drive the rotating rod to rotate, and the rotating rod will drive the driving gear to rotate. The driving gear will drive the annular gear ring to rotate the supporting tube 90 degrees, thereby moving the next group of worms to be polished to the bottom of the polishing device, so that the polishing device can polish the next group of worms, thereby improving the efficiency of worm polishing.

[0019] In the present invention, when the supporting tube rotates to drive the worm to deflect toward the direction of the grinding device, the moving wheel will move to the plane with the inclined surface on the annular plate. At this time, when the moving frame moves to drive the clamping frame to move, the clamping frame will make the moving chuck drive the two clamping plates to clamp the worm, so that when the worm moves to the grinding device, the worm is in a clamped state, which is convenient for the subsequent adjustment device to drive the worm to rotate in a stable state, and can cooperate with the grinding device to fully grind the outer wall of the worm.

[0020] In the present invention, with the cooperation of the clamping device and the adjusting device, when the worm enters the placement cavity, the clamping device can first clamp the worm through the rotation of the carrying tube, and then move it to the grinding device after clamping, and the worm can be rotated under the drive of the adjusting device. After the worm contacts and grinds the grinding device, the worm can be unlocked with the rotation of the carrying tube, so that the worm can be taken out from the placement cavity. Through this process, the work efficiency of the worm grinding process can be quickly improved, and the worm can be continuously and intermittently fed into the placement cavity, so that the worm can be continuously ground.

[0021] In the present invention, when the placement cavity on the supporting cylinder corresponds to the loading push plate, the clamping rod will move to the vertical groove, and then driven by the reset spring, the worm placed on the support frame can be quickly pushed from the loading push plate to the placement cavity, thereby realizing continuous loading operation of the worm, allowing the processed worm to be continuously fed, and improving the processing efficiency of the worm.
