Description

Technical Field

[0001] This application relates to the field of bushing feeding technology, and in particular to a feeding device for a dual-channel volute bushing. Background Technology

[0002] A dual-flow-channel volute is a volute structure specifically designed for dual-flow-channel pumps. Its key feature is the presence of two independent flow channels, which significantly enhances the pump's anti-clogging and anti-winding properties. A bushing is a component used for connection or support between mechanical parts, its primary function being to reduce friction, wear, and vibration. During the manufacturing process of a dual-flow-channel volute, it is typically necessary to insert the bushing into the volute.

[0003] Currently, bushing insertion mainly relies on robotic arms to pick up the bushings at predetermined loading positions. Due to the different structures at both ends of the bushing, it must be placed in a specific orientation to facilitate picking by the robotic arm.

[0004] However, in practice, operators usually need to observe the bushing and place it in the correct orientation. When placing a large number of bushings, operators are prone to errors due to fatigue, resulting in inaccurate positioning of the bushing by the robotic arm, which affects the correct installation of the bushing on the dual-flow-channel volute. Utility Model Content

[0016] Optionally, the feeding section further includes a feeding trough located above the vibrating plate, and the height of the bottom of the inner wall of the feeding trough gradually decreases in the direction away from the vibrating plate and closer to the vibrating plate.

[0017] Optionally, the horizontal pushing part includes a pushing bar and a lateral pushing cylinder, wherein:

[0018] The push bar is placed in the conveying groove and slides in cooperation with the conveying groove;

[0035] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0036] This application discloses a feeding device for a dual-channel volute bushing.

[0037] A feeding device for a dual-channel volute bushing, used to place the bushing 1 at a predetermined feeding position, includes a worktable 2, a conveyor table 3, and a feeding unit 4. Both the conveyor table 3 and the feeding unit 4 are mounted on the worktable 2. The conveyor table 3 is provided with a conveying trough 31 for moving the bushing 1, and the feeding unit 4 is used to place the bushing 1 into the conveying trough 31. The bushing 1 moves horizontally in the conveying trough 31 via a horizontal pushing part 5, and moves vertically in the conveying trough 31 via a vertical pushing part 6.

[0038] The feeding unit 4 vertically places the bushing 1 into the conveying trough 31. Before placing the bushing 1 into the conveying trough 31, the feeding unit 4 changes the orientation of the bushing 1 so that all bushings 1 are vertically positioned and placed in the conveying trough 31 according to a specific orientation. Then, the horizontal pushing unit 5 moves the bushing 1 in the conveying trough 31 and moves it above the vertical pushing unit 6. During the movement of the bushing 1 inside the conveying trough 31, the inner wall of the conveying trough 31 guides and limits the bushing 1, reducing the possibility of the bushing 1 detaching from the conveying trough 31 during movement.

[0039] When the bushing 1 is delivered to the end of the conveying trough 31 by the horizontal pushing part 5 and is located directly above the vertical pushing part 6, it reaches the predetermined feeding position.

[0040] Then, the vertical pushing part 6 moves the bushing 1 in the vertical direction, pushing the bushing 1 out of the conveying groove 31 so that the bushing 1 can be picked up later.

[0041] The conveyor table 3 is equipped with an adjustment section 7, which is fixed at a predetermined feeding position and allows for adjustment of the height of the conveyor table 3. The adjustment section 7 includes a telescopic frame and a mounting plate 71, with the mounting plate 71 horizontally fixed at the top and bottom of the telescopic frame. The adjustment section 7 is mounted on the workbench 2 via the lowermost mounting plate 71, and the conveyor table 3 is fixedly mounted on the top of the uppermost mounting plate 71. The telescopic frame includes an upper fixing plate 72 and a lower fixing plate 73, with the upper fixing plate 72 mounted on the uppermost mounting plate 71 and the lower fixing plate 73 mounted on the lowermost mounting plate 71. The upper fixing plate 72 and the lower fixing plate 73 are parallel to each other, and the upper fixing plate 72 is mounted on the side wall of the lower fixing plate 73. The overall height of the adjustment section 7 is changed by altering the fixed position between the upper fixing plate 72 and the lower fixing plate 73. A feed inlet 32 ​​is provided on the side wall of the conveying trough 31, and the feeding section 4 places the bushing 1 into the conveying trough 31 through the feed inlet 32. After changing the orientation of the bushing 1, the feeding unit 4 places the bushing 1 into the conveying trough 31 from the feed inlet 32. The side wall of the feed inlet 32 ​​is provided with an inclined surface near the end of the conveying trough 31. When the horizontal pushing unit 5 pushes the bushing 1 from the feed inlet 32 ​​to move inside the conveying trough 31, the inclined surface at the feed inlet 32 ​​guides the bushing 1 so that the bushing 1 can be completely inserted into the conveying trough 31, reducing the possibility that the horizontal pushing unit 5 will squeeze the bushing 1 out of the feed inlet 32 ​​into the conveying trough 31 when pushing the bushing 1.

[0042] The feeding section 4 consists of a vibratory feeder 41 and a feeding trough 42. The discharge end of the vibratory feeder 41 is located at the inlet 32. Bushings 1 are poured into the vibratory feeder 41 in batches. The orientation of the bushings 1 is adjusted by the vibratory feeder 41, and the adjusted bushings 1 are gradually conveyed to the inlet 32 ​​via vibration, thus simultaneously conveying and adjusting the orientation of the bushings 1. The feeding trough 42 is located above the vibratory feeder 41, and the height of the bottom of the inner wall of the feeding trough 42 gradually decreases from away from the vibratory feeder 41 to closer to it. When feeding material into the vibratory feeder 41, bushings 1 are poured into the feeding trough 42 in batches. The feeding trough 42 guides the bushings 1 into the vibratory feeder 41, allowing workers to replenish the bushings 1 into the vibratory feeder 41 from outside the processing area, thus improving worker safety.

[0043] The horizontal pushing unit 5 includes a pushing bar 51 and a transverse pushing cylinder 52. The pushing bar 51 is placed in the conveying trough 31 and slides in cooperation with it. The pushing cylinder is mounted on the conveying table 3, and the end of the pushing rod of the pushing cylinder is connected to the end of the pushing bar 51. When the bushing 1 moves inside the conveying trough 31, the push rod of the transverse pushing cylinder 52 pushes the bushing 1 to move inside the conveying trough 31 through the pushing bar 51. The end of the pushing bar 51 pushes the bushing 1 to move, and the pushing bar 51 pushes the top and bottom of the bushing 1 to move synchronously, which improves the stability of the bushing 1 moving inside the conveying trough 31 and reduces the possibility of the bushing 1 tipping over during the conveying process in the conveying trough 31. At the same time, when the pushing bar 51 pushes the bushing 1, it gradually covers the feed inlet 32 ​​to block the feed inlet 32, so as to ensure that there is only one bushing 1 in the conveying trough 31 and ensure the conveying rhythm of the bushing 1.

[0044] A limiting plate 33 is provided at the top of the conveying trough 31. During the movement of the pushing part, the limiting plate 33 and the inner wall of the conveying trough 31 cooperate to limit the pushing bar 51, thereby improving the stability of the pushing bar 51 moving inside the conveying trough 31 and reducing the possibility of the pushing bar 51 tilting during the movement, resulting in uneven force on the top and bottom of the bushing 1 and causing it to tip over.

[0045] The vertical pushing part 6 includes a pushing seat 61 and a vertical pushing cylinder 62. A pushing port is provided at the bottom of the inner wall of the conveying trough 31. The pushing seat 61 is placed at the pushing port and is inserted into it. The vertical pushing cylinder 62 is mounted on the conveying table 3, and the push rod of the vertical pushing cylinder 62 is connected to the pushing seat 61. After the bushing 1 moves to the pushing port in the conveying trough 31, the bushing 1 is placed on the pushing seat 61, which supports and positions the bushing 1. Then, the vertical pushing cylinder 62 pushes the bushing 1 vertically out of the conveying trough 31 via the pushing seat 61, facilitating subsequent pickup of the bushing 1.

[0046] The push base 61 includes a plug-in rod 611 and a limiting ring 612. The plug-in rod 611 is mounted on the top of the push rod of the vertical push cylinder 62, and the plug-in rod 611 and the bushing 1 are plugged into each other. The limiting ring 612 is mounted on the plug-in rod 611, and the bottom of the bushing 1 contacts the top of the limiting ring 612. When the bushing 1 is placed at the push port, the bushing 1 is fitted onto the plug-in rod 611 under the action of gravity, and the bottom of the bushing 1 contacts the top of the limiting ring 612. The bushing 1 is positioned by the plug-in rod 611 and the limiting ring 612, so as to improve the stability and positional accuracy of the bushing 1 movement.

[0047] In this embodiment, the limiting ring 612 is a limiting nut, and the limiting nut and the plug rod 611 are threaded together. The relative position of the bushing 1 and the plug rod 611 is adjusted by rotating the limiting nut.

[0048] The implementation principle of the feeding device for a dual-channel volute bushing according to an embodiment of this application is as follows: automatic feeding of the bushing 1 is achieved through a series of precisely matched components. First, the vibratory feeder 41 of the feeding unit 4 receives and adjusts the orientation of the bushing 1 to make it vertically aligned, and then the bushing 1 is fed into the conveying trough 31 through the feed inlet 32. In the conveying trough 31, the transverse pushing cylinder 52 of the horizontal pushing unit 5 drives the pushing bar 51 to move the bushing 1 horizontally to above the vertical pushing unit 6. During this process, the inner wall of the conveying trough 31 and the limiting plate 33 work together to ensure the stable movement of the bushing 1 and prevent it from tipping over or falling out of the conveying trough 31. When the bushing 1 reaches the designated position, the vertical pushing cylinder 62 of the vertical pushing unit 6 pushes the bushing 1 out of the conveying trough 31 vertically through the pushing seat 61, completing the feeding process. The height of the conveying table 3 can be flexibly adjusted by the telescopic frame of the adjusting unit 7 and the mounting plate 71 to adapt to different production needs. In addition, the design of the feeding trough 42 of the feeding section 4 allows workers to safely replenish the bushing 1 outside the processing area, improving the safety and convenience of operation.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
