Description

Technical Field

[0001] This utility model relates to the field of automated cylinder assembly equipment, and in particular to a multi-part number piston rod quantitative feeding device. Background Technology

[0002] The main components of a cylinder include the cylinder body and the piston rod. Currently, automated cylinder assembly lines aim to reduce manual labor and achieve full automation. Therefore, during piston rod assembly, precise conveying of the piston rod is crucial to prevent assembly deviations. However, due to the different specifications of cylinders, the piston rod specifications, including length and diameter, vary. This necessitates the use of multiple different conveying structures, resulting in higher costs. Ideally, these should be integrated into a single conveying system. Furthermore, a challenge arises when conveying piston rods with different diameters at both ends. Precise positioning of the piston rod is required, and if the conveying device cannot perfectly match the diameter difference between the front and rear ends, the piston rod may become stuck and fail to fall, impacting the entire automated line's operation.

Detailed Implementation

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] like Figure 1 As shown, this utility model proposes a multi-material-number piston rod quantitative feeding device, including...

[0025] An adjusting trough 1 is provided, with an opening 2 at the top for piston rods to enter. The adjusting trough 1 is used to hold a batch of piston rods. The length of the adjusting trough 1 can be adjusted according to the length of the piston rods. A rotating feeding assembly 3 is provided inside the adjusting trough 1. When assembling piston rods of a certain length, the length of the trough is adjusted.

[0026] Specifically: such as Figure 2 As shown, the adjusting trough 1 includes an end plate 22 and panels 23 located on both sides of the end plate 22. The end plate 22 and the panels 23 form a cavity. The lower part of the two panels 23 has a slot for the product to fall. A conveyor belt 16 is provided at the bottom for conveying. A slide rail 24 is provided on the panel 23. A limiting plate 25 is slidably connected to the slide rail 24. A baffle 26 is provided between the opposing limiting plates 25. The bottom of the baffle 26 presses against the limiting block 14 and the rotating feeding assembly 3. The baffle 26 is configured to cooperate with the rotating feeding assembly 3. A pulling device 27 is connected to one of the limiting plates 25. The pulling device 27 drives the limiting plate 25 to slide on the panel 23. The pulling device 27 can be a cylinder or a lead screw module. Depending on the piston rod of different lengths, the conveying limiting plate 17 can be pulled by the pulling device 27, which can pull the baffle 26 to move above the entire cavity. It is suitable for piston rods of different lengths. The rotating feeding assembly 3 can drive the falling piston rod to rotate and fall onto the lower conveyor belt 16.

[0027] like Figure 3 , Figure 4 , Figure 5As shown, the rotating feeding assembly 3 is located inside the adjusting feed trough 1, and includes a continuously arranged feeding plate assembly. The feeding plate assembly includes a fixed feeding plate 4 and a movable feeding plate 5, and the movable feeding plate 5 has a protrusion 6 at its center. The protrusion 6 is inserted into the center of the fixed feeding plate 4 on the adjacent side, which can more stably ensure the connection between a set of fixed feeding plates 4 and movable feeding plates 5. The fixed feeding plate 4 has a plurality of positioning round holes 9 arranged circumferentially, and the movable feeding plate 5 has a plurality of arc-shaped holes 10. The positioning round holes 9 and the arc-shaped holes 10 correspond to each other. A positioning rod passes through the hole, between the circular hole and the arc-shaped hole 10. The circular hole of the fixed lever 4 fits perfectly with the positioning rod. The positioning rod passes from one end of the lever assembly to the other end. In this embodiment, four sets of positioning rods are provided. The corresponding circular holes are arranged circumferentially on the surface of the fixed lever 4, and the arc-shaped holes 10 are evenly distributed circumferentially on the surface of the movable lever 5. After the fixed lever 4 is positioned by the four sets of positioning rods, it is relatively stationary, while the movable lever 5 can rotate relative to the fixed lever 4. The surfaces of the fixed lever 4 and the movable lever 5 are provided with multiple sets of adjustment holes 12 with different degrees of overlap. For details on the degree of overlap, see [link to relevant documentation]. Figure 7 The adjustment hole 12 corresponds to the V-shaped receiving groove. The pin 13 passes through the adjustment hole 12 located at both ends of the rotating feeding assembly 3 and is used to determine the size of the opening 2 of the V-shaped receiving groove 11. By inserting the pin 13, a certain set of adjustment holes 12 coincide, that is, the movable actuating plate rotates relative to the fixed actuating plate 4 along the arc-shaped hole 10. That is, the opening 2 of the V-shaped receiving groove 11 on the circumference of the movable actuating plate 5 and the fixed actuating plate 4 changes to accommodate piston rods of different specifications. The two ends are locked by the pin 13 respectively, the end of the piston rod is positioned, and the movable plate in the middle position is adjusted according to the diameter of the inserted piston rod.

[0028] When the piston rod falls into the V-groove, the piston rod can be driven to move by rotating the actuating assembly. Specifically, the center of the protrusion 6 of the movable actuating plate 5 is provided with a through hole 20, and the inner wall of the through hole 20 is provided with a slot 21. The drive shaft 7 passes through the through hole 20, and the drive shaft 7 is provided with a protrusion 28. The protrusion 28 is locked in the slot 21. When the drive shaft 7 rotates, it can drive the movable actuating plate 5 to rotate. The drive assembly 8 includes a drive motor 18, and the end of the drive motor 18 is connected to a synchronous pulley assembly 19. The synchronous pulley assembly 19 is connected to the drive shaft 7.

[0029] To ensure stable rotation of the piston rod within the adjusting trough 1 when it rotates in the V-shaped receiving groove 11, a limiting block 14 is provided on the side wall of the adjusting trough 1. Figure 6 As shown, the bottom of the limiting block 14 is provided with a feeding hole 15, and the limiting blocks 14 form a circular cavity that fits with the circumference of the movable paddle 5 and the fixed paddle 4.

[0030] The bottom of the adjusting trough 1 is provided with a conveyor belt 16, and a conveyor limiting plate 17 is provided on the conveyor belt 16, which limits the movement trajectory of the piston rod.

[0031] The working method of this utility model is as follows: according to the length of the piston rod to be conveyed, the length of the adjustable material groove is first adjusted by the pulling device 27. Then, according to the end diameter of the cylinder, the pin 13 is inserted into the corresponding adjustment hole 12 to adjust the width of the opening 2 of the corresponding V-shaped groove. After the piston rod of the cylinder completed in the previous process is sent into the adjustable material groove, it enters the determined V-shaped receiving groove 11. The drive device controls the drive shaft 7 to rotate, thus driving this rotation.
