Referring to fig. 5, after the metal rod abuts against the movable block 73 and forces the diagonal brace 76 to move in a direction away from the movable slot 621, the diagonal brace 76 can squeeze the first air bag 77 and force the first air bag 77 to shrink and deform inwards, and the air in the first air bag 77 can be transferred into the second air bag 78, so that the second air bag 78 expands and pushes the push-out block 75 to a side close to the clamping slot 611, and the effect of pushing the clamping block 71 out of the clamping slot 611 is achieved.

It can be appreciated that, after the swing rod 61 is reset to the initial state, the clamping block 71 is clamped into the clamping groove 611 again under the action of the elastic force of the first spring 72, so that the push-out block 75 can be forced to reset, and the second air bag 78 is pressed to enable the air in the second air bag 78 to return to the first air bag 77, so that the first air bag 77 is in the inflated state again, and the polishing process of the next metal rod piece is facilitated.

The inner diameter of the first air bag 77 is larger than the inner diameter of the second air bag 78 in this embodiment, so that the small-amplitude compressed length of the first air bag 77 can be converted into the large-amplitude expanded length of the second air bag 78, and further the moving distance of the push-out block 75 in the push-out groove 612 is increased, so that the push-out block 75 can smoothly push out the clamping block 71 from the clamping groove 611.

In addition, it should be noted that, after the metal rod member simultaneously abuts against the two sets of positioning mechanisms 7 and releases the positioning of the deflection link 61, the metal rod member moves forward and pushes the deflection link 61 to rotate, and at this time, the clamping block 71 can always abut against the side wall of the deflection link 61, so as to facilitate the torsion spring 63 to force the deflection link 61 to reset automatically after the metal rod member leaves the deflection link 61.

The implementation principle of the metal rod piece polishing equipment provided by the embodiment of the application is as follows:

When polishing the metal rod pieces of various sizes, the metal rod pieces enter the two spiral grooves 31 of the two conveying rods 3 through the feeding mechanism 9 and enter the channel between the conveying rods 3 and the pressing guard plate 52 along with the rotation of the conveying rods 3; when the metal rod member enters, the whole body is in an inclined state, and one side end of the metal rod member is abutted with one of the resisting rods 62, and the specific process is as follows: the metal rod abuts against the bearing part 731, so that the movable block 73 is forced to retract into the movable groove 621, at this time, the first guide surface 761 of the movable block 73 can abut against the second guide surface 732 of the diagonal brace 76, and further drive the diagonal brace 76 to move towards the direction close to the unlocking groove 613, the first air bag 77 is extruded to be forced to shrink, and air of the first air bag 77 flows into the second air bag 78 through the air pipe, so that the second air bag 78 is inflated and expanded, and the pushing block is forced to push the clamping block 71 out of the clamping groove 611, so that the locking of the clamping block 71 to the eccentric swing rod 61 is released.

When one side end of the metal rod member is abutted against one abutting bar 62, the other group of positioning mechanisms 7 still keeps locking the offset swinging rods 61, at the moment, the metal rod member is still conveyed forwards on the two conveying rods 3, the metal rod member is abutted against one side of the abutting bars to jump and force the pressing guard plate 52 to slide upwards, and the possibility that the metal rod member is clamped between the conveying rods 3 and the pressing guard plate 52 is reduced, so that polishing operation can be conveniently and normally performed.

After the other side end of the metal rod is abutted against the other abutting rod 62, the metal rod is adjusted to be perpendicular to the two conveying rods 3, and in this state, the metal rod abuts against the bearing parts 731 on the two abutting rods at the same time, so that the locking of the two groups of positioning mechanisms 7 to the deflection rods 61 can be simultaneously released, and further when the conveying rods 3 drive the metal rod to continue to travel, the deflection rods 61 can rotate, so that the metal rod is conveyed forwards along the axial direction of the conveying rods 3, and the polishing processing of the two ends of the metal pipe fitting by the follow-up polishing mechanism 2 is facilitated.

The above is a preferred embodiment of the present application, and is not intended to limit the scope of the present application in this way, therefore: all equivalent changes in structure, shape and principle of the application should be covered in the scope of protection of the application.
