[0002] The cylinder block main bearing cap is one of the key components of the engine. In the engine, it is usually used to connect the cylinder block to fix and support the engine crankshaft and is located at the bottom of the engine. After being equipped with the bearing bush, it can ensure that the crankshaft rotates easily in the circumferential direction and restrict the axial movement of the crankshaft. The most critical function of the cylinder block main bearing cap is to bear the cyclic alternating load applied during the engine's operation to ensure the efficient operation of the engine. However, the positioning pin is one of the indispensable parts for the assembly of the main bearing cap. The traditional installation of the positioning pin uses manual feeding, which requires manually placing the parts or products on the production line, consuming time and labor, with low production efficiency, and it is difficult to guarantee the product quality. There are also some automatic feeding mechanisms that have problems such as high cost, high rejection rate, waste of beats, and difficult maintenance. Summary of the Utility Model

The ends of the clamping pin cylinder 23 and the material blocking cylinder 24 are respectively connected to a clamping rod 25 and a material blocking rod 26. The moving material path mechanism includes a moving material path seat 20 and a guide pin plate 29 fixed on a bottom plate 18. The bottom plate 18 is installed on a linear guide 19. The guide pin plate 29 is fixed on the moving material path seat 20. The guide pin plate 29 has holes on both sides for a full material switch 6 and a material shortage switch 5 of the moving material path connected to the guide pin plate 29 to detect the feeding situation in the guide pin plate 29. The slide table feeding mechanism includes a slide table cylinder 17 and a slideway 11. The slide table cylinder 17 is fixed on the bottom plate 18 and moves with the bottom plate 18. The slideway 11 is fixed on the slide table cylinder 17 through a slideway mounting plate 16. A baffle 8, a switch mounting plate 10, a material presence switch 9 and a feeding cylinder 13 are installed on the slideway 11. A plate 14 and an ejector rod 15 are installed on the feeding cylinder 13.

[0019] The vibrating bowl 1 is connected to the transition plate 2 by bolts and positioned through a positioning sleeve 4, so that the vibrating bowl 1 is seamlessly butted with the fixed material path 3.

[0020] Both the clamping rod 25 and the material blocking rod 26 are connected to the material distribution seat 21 through copper sleeves 26 embedded in the material distribution seat 21.

[0021] The bottom plate 18 is mounted on the linear guide 19 by bolts. The guide pin plate 29 is fixed on the moving material channel base 20 by bolts. The full material switch 6 and the material shortage switch 5 of the moving material channel are both fixed on the guide pin plate 29 by screws.

[0022] The sliding table cylinder 17 is a purchased finished product integrating a guide rail, a cylinder, a magnetic switch, and a limit device. It is fixed on the bottom plate 18 by bolts. The feeding cylinder 13 is a double-guided cylinder and is fixed on the feeding cylinder 13 by the feeding cylinder mounting L plate 12.

[0023] All the switches used in the device are opposed switches. The vibrating bowl 1, the linear guide 19, and the fixed material channel 3 are all fixed parts. Embodiment 2

[0024] The working process of the present utility model is as follows:

[0025] As Figure 1 、 Figure 3 , first, the initial state is the material receiving state. The moving material channel part is at the leftmost side. The fixed material channel 3 is always full of materials. When the fixed material channel 3 is not full, the fixed material channel material shortage switch 7 detects it and issues a material shortage command. The vibrating bowl 1 starts to drop materials until the fixed material channel 3 is full. As Figure 6 , at this time, the blocking cylinder 24 is always in the extended state to block the positioning pin 28 from falling. When the moving material channel part and the fixed material channel part are butted, the moving material channel material shortage switch 5 of the moving material channel part sends a signal to start dropping materials. At this time, the blocking cylinder 24 retracts, and the clamping pin cylinder 23 extends to ensure that one material drops at a time. The two cylinders work alternately. When 5 materials drop, the moving material channel full material switch 6 sends a signal, and the fixed material channel part stops dropping materials. The moving material channel part always maintains five positioning pins 28. In actual application, four positioning pins 28 are pressed. One more is to prevent defective products and save the beat; As Figure 3 , then the sliding table cylinder 17 slides to the butting position with the moving material channel part. The positioning pin 28 naturally drops into the circular groove of the slideway 11 by gravity. Then the material presence switch 9 of the slideway 11 detects that there is material in the slideway 11. As Figure 4 , after the sliding table cylinder 17 slides to the right and reaches the position, the feeding cylinder 13 drives the plate 14 and the ejector rod 15 to send out the positioning pin. Then the material presence switch 9 detects that there is no material in the slideway 11. The sliding table cylinder 17 continues to slide to the butting position with the moving material channel part and continues to receive materials. This action is repeated until the moving material channel material shortage switch 5 detects that there is no material in the moving material channel part. The moving material channel part returns to butt with the fixed material channel part to receive materials. Thus, one pressing ends.
