Description

Technical Field

[0001] The present invention relates to the technical field of part processing equipment, and particularly to a part processing production line transfer process and its transfer structure. Background Art

[0002] The plunger pump is an important device in the hydraulic system. It relies on the reciprocating movement of the plunger in the cylinder block to change the volume of the sealed working chamber to achieve oil suction and oil pressure. The plunger pump has the advantages of high rated pressure, compact structure, high efficiency, and convenient flow regulation. The plunger pump is widely used in occasions such as high pressure, large flow, and flow regulation requirements, such as hydraulic presses, construction machinery, and ships.

[0003] Currently, when processing a relatively complex plunger pump part, multiple processes are usually required. For example, during the forming process of general steel or aluminum parts, the following basic steps are mostly required: turning of the blank, deburring, finish milling, deburring, cleaning, etc.; and when the spatial span between two process equipment is large, or the time difference between the completion of two processes is large, and the previous process only requires less time while the next process requires longer time, the parts processed in the previous process will accumulate. At this time, it is not very suitable to use the conveyor belt on the assembly line for transfer. Therefore, it is generally necessary to manually collect and transport these trays containing parts to the designated position for processing, which is rather troublesome. At the same time, workers need to walk back and forth between the two workstations, affecting production efficiency. For this reason, we propose a part processing production line transfer process and its transfer structure. Summary of the Invention

A rack five 121 meshing with the gear disk ten 117 is slidably connected to the mounting frame 3. The rack five 121 is fixedly connected to the rack four 118. One end of the rack four 118 is fixedly connected to a connecting rod fixedly connected to the rack five 121, and a sliding sleeve is fixedly connected to the mounting frame of the conveyor belt 1. The connecting rod slides through the sliding sleeve. Rotating the shaft eleven 119 drives the gear disk ten 117 to rotate, thereby driving the rack five 121 to move, and further driving the rack four 118 to move.

[0085] A gear disk eleven 122 is fixedly connected to the shaft eleven 119. An arc - shaped plate 123 is fixedly connected to the shaft six 88. A plurality of tooth grooves two 124 meshing with the arc - shaped plate 123 are evenly and equidistantly arranged on the arc - shaped plate 123. Rotating the shaft six 88 drives the arc - shaped plate 123 to rotate, thereby driving the gear disk eleven 122 to rotate, and further driving the shaft eleven 119 to rotate.

[0086] During the normal operation of the material transfer structure of the part processing production line, the AGV cart 5 automatically detaches from the conveyor belt 1 and transports the parts to the processing location of the next process, thus avoiding the need for workers to walk back and forth between two workstations to carry the parts, which is more convenient. At the same time, it saves the working time of the workers and improves the production efficiency. When the AGV cart 5 returns to the storage space after feeding, the first tooth groove 79 drives the fourth gear 77 to rotate, which in turn drives the fifth gear 78 to rotate, thereby driving the two third shafts 74 to rotate and using the first synchronous pulley 75 to cooperate with the synchronous belt to drive the second shaft 72 and one first shaft 67 to rotate, thereby driving the third gear 73 to rotate, which in turn drives the second gear 71 to rotate, thereby driving the two first shafts 67 to rotate synchronously, which in turn drives the first gear 68 to rotate, thereby driving the first rack 69 to move, which in turn drives the sliding block 62 to move, thereby driving the tray to displace above the AGV cart 5. At the same time, the limit plate 66 presses the push switch 64 to cut off the power supply of the electromagnet 63, so that the tray falls into the placement groove 65, thus automatically completing the assembly operation of the tray, which is more convenient. At the same time, when the AGV cart 5 returns to the storage space after feeding, it drives the seventh gear 98 to rotate, which in turn drives the sixth gear 97 to rotate, thereby driving the seventh shaft 93 to rotate, which in turn drives the second screw 94 to rotate, thereby driving the movable plate 95 to move, which in turn drives the support rod 89 to move downward to cancel the support for the collection box 2. At the same time, when the AGV cart 5 completely enters the storage space, it pushes the second round rod 109 to move, which in turn drives the second piston 108 to move, so that air is filled into the first injection barrel 103, thereby driving the first piston 104 to move, which in turn drives the two first round rods 105 to move, so that the locking plate 102 moves away from the convex block 101, thereby releasing the lock on the collection box 2, so that it deflects and dumps the parts, thus automatically completing the feeding operation of the AGV cart 5, which is more convenient.
