Referring to fig. 1 to 4, an embodiment of the present application discloses an automatic processing apparatus including a housing 1; a main shaft 2 penetrating the housing 1; a positioning device at least partially penetrating the main shaft 2;

the positioning device comprises a positioning mechanism 4 arranged in the main shaft 2, a pull rod 3 connected with the positioning mechanism 4 and capable of enabling the positioning mechanism 4 to move along the axial direction of the main shaft 2, and a driving mechanism 5 connected with the pull rod 3 and capable of enabling the pull rod 3 to move along the axial direction of the main shaft 2;

a first anti-rotation mechanism 6 is arranged between the positioning mechanism 4 and the pull rod 3; a second anti-rotation mechanism 7 is arranged between the driving mechanism 5 and the pull rod 3.

With the above structure, the positioning mechanism 4 can rotate with the spindle 2, but the driving shaft 10 of the driving mechanism 5 can not rotate with the first rotation preventing mechanism 6 and the second rotation preventing mechanism 7, so that damage to the driving mechanism 5 can be avoided.

Referring mainly to fig. 1, in particular, the housing 1 constitutes the main body structure of the automatic processing apparatus, which is generally a frame made of a metal material. The main shaft 2 is arranged on the shell 1 in a penetrating way and can rotate relative to the shell 1 under the drive of a driving motor. The spindle 2 extends in an axial direction and is generally circular. The spindle 2 has a cavity 21 through which the positioning device is arranged. The end of the main shaft 2 extending out of the shell 1 is provided with a clamping jaw 9. The clamping jaw 9 is a three-jaw self-centering chuck in this embodiment. Of course, in other alternative embodiments, the clamping jaw 9 may have other configurations as desired.

The driving mechanism 5 can also drive the pull rod 3 and the positioning mechanism 4 to move along the axial direction of the main shaft 2 until the positioning mechanism 4 is abutted with the part to be machined while the clamping jaw 9 can process the part to be machined.

Specifically, the positioning mechanism 4 includes a positioning block 41 for abutting against a part to be machined. The outer peripheral side of the fixed outer block is provided with a plurality of seal rings 43 arranged at intervals in the axial direction. The seal ring 43 is also abutted against the inner side wall of the main shaft 2.

Referring to fig. 2, the first rotation preventing mechanism 6 includes a first bearing 61 connected to the tie rod 3 and a second bearing 62 rotatably connected to the positioning mechanism 4, and the first bearing 61 and the second bearing 62 abut. The first bearing 61 has an end face abutting against the second bearing 62, and the first bearing 61 has a stepped portion 611 facing away from the end face. The positioning mechanism 4 includes a pressing plate 42 fixed to the positioning block 41. The first bearing 61 is inserted into the platen 42 and is rotatable relative to the platen 42, and the step 611 abuts against the platen 42. The second bearing 62 is disposed inside the positioning block 41 and is rotatable relative to the positioning block 41. The first bearing 61 is connected to the tie rod 3 by a predetermined bolt 63. For example, in the present embodiment, the first bearing 61 may be rotatably connected to the tie rod 3. Of course, the first bearing 61 may also be fixedly or rotatably connected to the pull rod 3. The prescribed bolt 63 is provided between the first bearing 61 and the second bearing 62.

During the movement, when the driving shaft 10 pushes the pull rod 3 to move rightward, the pull rod 3 drives the first bearing 61 to move, and the first bearing 61 pushes the second bearing 62 and the positioning mechanism 4 to synchronously move rightward. When the driving shaft 10 pushes the pull rod 3 to move leftwards, the pull rod 3 drives the first bearing 61 to move, and the first bearing 61 drives the positioning mechanism 4 to synchronize leftwards through the step 611. During the above movement, the positioning mechanism 4 rotates relative to the positioning mechanism 4 during the rotation of the spindle 2, so that the torsion of the pull rod 3 is basically avoided, and the rotation of the pull rod 3 is avoided as much as possible.

Referring to fig. 3, the second rotation preventing mechanism 7 includes a fixing sleeve 71 provided on the driving shaft 10 of the driving mechanism 5, a third bearing 72 rotatable with respect to the fixing sleeve 71, and a fourth bearing rotatably connected to the second bearing 62, and further connected to the pull rod 3.

An internally threaded sleeve 73 can also be detachably provided on the fixing sleeve 71. In other words, the driven shaft 10 is screwed with the fixing sleeve 71 by a screw. The female screw sleeve 73 is screwed to the fixing sleeve 71. One side of the third bearing 72 may abut against an end surface of the fixed sleeve 71, and the other side of the third bearing 72 may abut against the female sleeve 73. And the third bearing 72 may also be fixedly or rotatably connected to the tie rod 3 by means of bolts. Preferably, the number of the third bearings 72 is two, and the two third bearings 72 are aligned and abutted in the axial direction of the main shaft 2. The pull rod 3 is further formed with a radially outward protruding portion 31, and the third bearing 72 closer to the protruding portion 31 is also abutted against a side surface of the protruding portion 31.

During the movement, when the driving shaft 10 moves rightwards, the fixing sleeve 71 is driven to move rightwards, and the fixing sleeve 71 pushes the third shaft to drive the pull rod 3 to move rightwards synchronously. When the driving shaft 10 moves leftwards, the female screw sleeve 73 drives the third bearing 72 to move synchronously, so that the pulling plate is synchronized leftwards. During the above-described movement, although the tie rod 3 is not twisted substantially or with a high probability by the first rotation preventing mechanism 6, even when a slight twisting force or torsion is applied, the third bearing 72 is rotated with respect to the drive shaft 10, and thus the tie rod 3 does not rotate the drive shaft 10, thereby causing no damage to the drive shaft 10.

In the present embodiment, the first bearing 61 and the second bearing 62 may be halbimerfed HRBMKF-NKXR20, and the third bearing 72 may be halbimerfed HRBMKF-NKXR15.

Referring to fig. 4, the tie rod 3 is preferably connected to the housing 1 by a composite bearing 8. The shell 1 is provided with a bearing seat 81, and the composite bearing 8 is arranged in the shaft of the bearing seat 81 in a penetrating way. The composite bearing 8 is sleeved on the pull rod 3.

In addition, the automatic processing equipment only needs to input the needed size into the control panel, and the positioning device can automatically adjust the length size of the processed workpiece under the action of the driving shaft 10 of the driving mechanism 5. Therefore, the repeated tool setting time can be saved, the machining efficiency is greatly improved, and the accurate positioning in the length direction is realized by utilizing a mechanical structure and an electrical control system.

The above disclosure is only a preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model, so that all equivalent technical changes made by the specification and drawings of the present utility model are included in the scope of the present utility model.
