the feeding assembly is also provided with a distributing wheel lower baffle 129 and a distributing wheel upper baffle 130 which are arranged on the upper side and the lower side of the distributing wheel 114 and between the first bracket 106a and the second bracket 106 b; the feeding assembly further comprises a material reverse detection device, which is arranged on the upper baffle 130 of the material distributing wheel 114 and comprises a detection rod 132 and a proximity switch 136, wherein the proximity switch 136 is arranged on the upper baffle 130 of the material distributing wheel through a proximity switch bracket 135, one end of the detection rod 132 is abutted with the outer diameter of the reverse workpiece or the groove diameter of the normal workpiece, and when the reverse workpiece is abutted with the detection rod 132, the other end of the detection rod 132 triggers the proximity switch 136.

In this embodiment, all cylinders are made of brand name of Sudoku.

Before the equipment runs, a certain amount of products to be processed are manually placed into the hopper (because the products are divided into the front end and the back end, the products need to be manually placed into the hopper in the correct direction). The hopper is internally provided with a material distributing wheel which rotates periodically. The material distributing wheel is provided with arc grooves which are evenly distributed along the circumference, and a pair of arc grooves are respectively positioned right above and right below the motor in each rotation. At this point, a workpiece will drop into the slot directly above, with the slot directly below being aligned with the slot in the lower stop 129 of the feed wheel. The workpiece falls on the lower V-shaped groove guide rail through the long hole, and the motor rotates every time to finish the workpiece conveying process. When the lower optical fiber sensor 124 senses that the workpiece is on the V-groove guide rail 104, the rear material pushing cylinder 118 pushes forwards, the workpiece is pushed into the front jig hole through the push rod 121, and the push rod 121 and the threaded cylinder 122 are mounted at the front end of the piston rod of the material pushing cylinder 118 through the connecting rod 120 (the threaded cylinder 122 is mounted on the push rod 121). The purpose is that the workpiece can be displaced in two sections when pushed, and firstly, the workpiece is not pushed onto the positioning surface in the jig when the pushing cylinder 118 reaches the stroke end, but has a certain gap. And the screw cylinder 122 in front pushes the workpiece to move for the second section again, so that the workpiece is jacked on the positioning surface of the jig, and the axial position of the workpiece is ensured to be accurate. Because the thrust of the material pushing cylinder 118 is not applied to the jig positioning surface, only the thrust of the thread cylinder 122 pushes the workpiece against the jig positioning surface. Therefore, the pressure applied to the workpiece impacting the positioning surface of the jig can be greatly reduced. After the workpiece is in place, the pusher cylinder 118 retracts to wait for the next workpiece to be in place.

The feed reverse detection device is provided on the feed wheel upper flap 130, while the feed wheel lower flap 129 is designed to be manually openable (a flip flap). The principle of material reverse detection is as follows: the detection position corresponds exactly to the indexing position of the circular arc groove of the distributing wheel 114. When the dispensing wheel 114 rotates the workpiece to this position, the workpiece will push up the detection rod 132 (the detection rod 132 is reset by the spring 133). If the workpiece orientation is reversed, the sensing bar 132 contacts the outer diameter of the workpiece and conversely the groove diameter of the workpiece, the upper feed proximity switch 136 is triggered by the difference in height between the outer diameter of the workpiece and the groove diameter of the workpiece. When the workpiece is inverted, the upper feed proximity switch 136 is triggered because the detection rod 132 is raised to a height greater than the height of the upright workpiece. And because the servo motor 117 is triggered by a pulse signal every time it is indexed (the motor rotates a fixed angle every time it receives a fixed amount of pulse signal). When the proximity switch feeding proximity switch 136 of material reversal detection is switched on, the equipment stops and gives an alarm after the lower motor servo motor 117 receives two pulse signals, at the moment, the detected workpiece just stops at the movable baffle of the lower baffle 129 of the material distribution wheel, the lower baffle 129 of the material distribution wheel needs to be opened manually, and the equipment is restarted after the workpiece is taken out. The purpose of material reversal detection is to prevent the work piece from being reversed by manual error to cause waste.

Meanwhile, the feeding assembly also has a blanking function, and after one workpiece is machined, the cylinder of the X-axis assembly drives the jig assembly above the workpiece to move. And moving the jig for processing the workpiece to a blanking position for blanking, moving the other jig to a processing position for repeating the feeding processing process (the two jigs alternately and circularly carry out feeding processing and blanking). When the jig reaches the blanking position, the blanking cylinder 126 drives the blanking air claw 128 to extend out to clamp the workpiece, then the diaphragm chuck of the jig is loosened, and the blanking cylinder 126 retracts and drives the blanking air claw to draw the workpiece out of the jig 302. After the blanking air cylinder 126 is reset, the blanking air claw 128 is opened, and the workpiece falls on the lower conveyor belt 4 and is conveyed to a finished product box outside the equipment.

As shown in fig. 6, the feeding assembly of the present invention is applied to a mechanism body of a motor shaft hole processing device, and the mechanism body further includes a Z-axis assembly 2, an X-axis assembly 3 and a conveyor belt 4, wherein the feeding assembly 1, the Z-axis assembly 2 and the X-axis assembly 3 are all mounted on a working table of a bed body a, and the conveyor belt 4 is mounted on a side edge of the X-axis assembly 3 and right below a blanking clamping jaw.

The feed assembly 1 is matched with the X shaft assembly 3, automatic feed of the X shaft assembly 3 is completed, the traditional manual feed operation mode is replaced, the efficiency is greatly improved, the feed is accurate in place, the labor intensity of operators is reduced, and the rejection rate is reduced.
