[0016] like Figures 1-8 As shown, this utility model embodiment provides an automatic workpiece shaft feeding device, which is installed on an automated grinding equipment. It includes: a feed mounting base 10, a rotary drive mechanism 20 disposed on the feed mounting base, a workpiece chuck 30 connected to the rotary drive mechanism, and a workpiece feeding mechanism 40 disposed on the feed mounting base and connected to the rotary drive mechanism.

[0017] The rotary drive mechanism 20 includes: a workpiece rotary motor 201 located at one end of the feed mounting base; a rotary transmission assembly 202 connected to the output end of the workpiece rotary motor; a workpiece rotary shaft 203 connected at one end; a rotary bushing 204 sleeved outside the workpiece rotary shaft and located at one end inside the feed mounting base; two rotary bearings 205 respectively located inside the two ends of the rotary bushing and sleeved on the workpiece rotary shaft; and a rotary connector 206 connected to the other end of the workpiece rotary shaft, arranged along its axial direction, and located outside the rotary bushing; one end of the workpiece chuck 30 is inserted into and connected to the rotary connector.

[0018] The rotary transmission assembly 202 includes a drive gear 202a connected to the output end of the workpiece rotary motor and located in the feed mounting base, and a driven gear 202b perpendicularly connected to one end of the feed mounting base and meshing with the drive gear; one end of the workpiece rotary shaft 203 is inserted into the driven gear and is arranged along the length direction of the feed mounting base.

[0019] It also includes: a feed push rod 207 inserted into the axial hole of the workpiece rotating shaft and with one end located outside the end of the workpiece rotating shaft connected to the driven gear; a feed pull rod 208 located in the axial hole of the workpiece rotating shaft and with one end abutting against the other end of the feed push rod; and a feed spring 209 located in the axial hole of the workpiece rotating shaft and sleeved outside the feed pull rod.

[0020] The feed rod 208 has a feed end plate 208a perpendicular to the feed rod at one end that abuts against the feed push rod, and one end of the feed spring abuts against the inner surface of the feed end plate; the feed rod is connected to one end of the workpiece chuck 30.

[0021] The workpiece feeding mechanism 40 includes: a feed mounting plate 401 disposed on one side plate of the feed mounting base 10; a lead screw mounting seat 402 and a feed base 403 disposed on the feed mounting plate; a feed motor 404 disposed at one end of the feed base; a feed coupling 405 disposed inside the feed base and connected to the output end of the feed motor; a feed lead screw 406 whose one end passes vertically through the end plate at the other end of the feed base and extends into the feed base and is connected to the feed coupling, and whose other end is connected to the lead screw mounting seat; a feed lead screw nut 407 movably sleeved on the feed lead screw; a first connecting plate 408 whose one end is vertically connected to the feed lead screw nut; and a second connecting plate 409 whose one end is connected to the first connecting plate and whose other end passes vertically through one side plate of the feed mounting base 10 and is vertically connected to the rotating bushing 204.

[0022] It also includes an adjustment mechanism 50; the adjustment mechanism includes: two adjustment columns 501 located at one end of the feed mounting base 10, parallel to each other and located on one side of the workpiece rotary motor 201; an adjustment plate 502 vertically connected to the free ends of the two adjustment columns; a feed adjustment screw 503 with one end vertically passing through the adjustment plate and abutting against one end of the feed push rod 207; and a rotary handle 504 located at the other end of the feed adjustment screw.

[0023] The other end of the feed mounting base 10 is provided with a mounting cylinder 101 that is sleeved on the outside of the rotating bushing 204 and integrally formed with the feed mounting base; the other end of the rotating bushing is provided with a circular ring 210 located outside the feed mounting base.

[0024] During processing, after the workpiece rotary motor 201 starts, it drives the drive gear 202a to rotate, which in turn drives the driven gear 202b to rotate. Since the driven gear 202b is sleeved outside the workpiece rotating shaft 203, the workpiece rotating shaft 203 rotates accordingly, and the rotary connector 206 rotates accordingly, thereby driving the workpiece chuck 30 to rotate, thus driving the workpiece to rotate. At the same time, after the feed motor 404 starts, it drives the feed screw 406 to rotate, and the feed screw nut 407 moves forward along the feed screw. The first connecting plate 408, one end of which is connected to the feed screw nut, ... The workpiece moves accordingly, causing the second connecting plate 409 to move as well. This, in turn, moves the rotating bushing 204, workpiece rotating shaft 203, rotating connector 206, workpiece chuck 30, feed ejector 207, feed pull rod 208, and feed spring 209 forward. The feed ejector 207 disengages from the feed adjusting screw 503, or there is no pressure between them. The workpiece chuck 30 carries the workpiece forward to the electric spindle grinding wheel mechanism of the grinding equipment for grinding. After the workpiece is processed, the workpiece rotating motor 201 stops rotating, and at the same time, the feed motor 404 starts and rotates in the opposite direction, driving the feed... When the lead screw 406 rotates in the reverse direction, the feed screw nut 407 moves backward along the feed screw. The first connecting plate 408, connected at one end to the feed screw nut, moves backward, causing the second connecting plate 409 to move as well. This, in turn, causes the rotating sleeve 204, workpiece rotating shaft 203, rotating connector 206, workpiece chuck 30, feed push rod 207, feed pull rod 208, and feed spring 209 to move backward. Once the feed push rod contacts the feed adjusting screw 503, the rotating sleeve, workpiece rotating shaft, and feed push rod continue to move. Because the feed push rod is fed... The adjusting screw presses, transmitting the pressure sequentially to the feed rod 208, causing it to move axially along the workpiece rotation axis and pushing the workpiece chuck 30 forward. The workpiece chuck opens to remove the finished workpiece and place a new workpiece. At this time, the feed spring 209 is compressed. Then, the feed motor 404 starts again, driving the rotating bushing 204, workpiece rotation axis 203, and other components forward. The feed push rod 207 disengages from the feed adjusting screw 503, the feed spring 209 is released, and the workpiece chuck 30 returns to its original position and closes to clamp the workpiece, allowing for the next processing cycle.

[0025] In the above description, it should be noted that the terms "installation", "connection", "connection" and other related terms should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components; "set at" should be understood as "installed at" or "set at", including installation methods such as fixed installation and movable installation.
