Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of transfer equipment, and in particular to a dual-station variable-distance clamping and transplanting mechanism for impeller production and processing. Background Technology
[0002] As a core component of mechanical equipment such as fans, pumps, and compressors, the impeller's processing quality directly affects the overall operating efficiency and stability of the machine. Furthermore, with the development of industrial intelligence, impeller production has gradually shifted towards flexible and automated production lines. In the automated impeller processing flow, the clamping and transferring mechanism is a key piece of equipment connecting different processes. Its core function is to precisely clamp the impeller from the feed tray of the preceding conveyor line and transfer it to the following conveyor line, achieving continuous flow between processes.
[0003] Currently, traditional clamping and transferring mechanisms on impeller production lines are mostly fixed-spacing dual-station or single-station designs. Once the clamping component spacing of such mechanisms is formed, it cannot be flexibly adjusted, and can only accommodate two conveyor lines with a specific spacing. However, in actual production, due to the diversity of impeller specifications (diameter, thickness, etc.) or the need for production line process optimization, the spacing of conveyor lines in different processes often needs to be adjusted. When the conveyor line spacing changes, traditional fixed-spacing mechanisms are difficult to adapt to the new installation requirements, necessitating the replacement of the entire clamping assembly or equipment modification. This not only increases equipment investment costs but also leads to extended production line downtime, severely restricting production efficiency. Utility Model Content
[0004] In order to enable the clamping and transplanting mechanism to flexibly adjust the distance between the clamping stations, adapt to two conveyor lines with different distances, and improve its practicality, this application provides a dual-station variable-distance clamping and transplanting mechanism for impeller production and processing.

[0017] This application discloses a dual-station variable-pitch clamping and transferring mechanism for impeller manufacturing. (Refer to...) Figure 1 , Figure 2 and Figure 3 The dual-station variable-pitch clamping and transplanting mechanism for impeller production and processing includes a frame 1, a swing arm 2 connected to the frame 1, the swing arm 2 being located above the frame 1, a drive assembly 3 for driving the swing arm 2 to rotate on the frame 1, a fixed plate 11 connected to the frame 1, the fixed plate 11 being located on one side of the frame 1 and having no movement interference with the swing arm 2, a positioning synchronous wheel 111 fixedly connected to the fixed plate 11, the axis of the positioning synchronous wheel 111 being collinear with the axis of rotation of the swing arm 2 to ensure transmission stability, and the swing arm 2 being located away from the positioning synchronous wheel 111. A fixed column 21 is connected to the end of the swing arm 2. A bearing synchronous wheel 211 is connected to the fixed column 21. A synchronous belt 4 is wound between the positioning synchronous wheel 111 and the bearing synchronous wheel 211. The synchronous belt 4 is arranged along the length direction of the swing arm 2. A mounting plate 5 is connected to the bearing synchronous wheel 211. Two movable plates 6 are slidably arranged at the end of the swing arm 2 away from the positioning synchronous wheel 111. A clamping component 7 is arranged on the movable plate 6. An adjustable connecting piece 8 is rotatably connected between the mounting plate 5 and the movable plate 6. The two adjustable connecting pieces 8 are arranged opposite to each other on the mounting plate 5.
[0018] The adjustable connector 8 includes a first connecting rod 81 and a second connecting rod 82. The first connecting rod 81 has two parallel oblong holes, and the second connecting rod 82 has two connecting holes corresponding to the two oblong holes. The oblong holes and the connecting holes are connected by bolts. The adjustable connector 8 allows adjustment of the length of the first connecting rod 81 and the second connecting rod 82 after they are joined together, so as to adjust the distance between the two movable plates 6, so that the clamping assembly 7 can be adapted to the preceding and following conveyor lines with different distances, or be compatible with the workpiece distance difference caused by the change of impeller specifications.
[0019] One end of the first connecting rod 81 is connected to the first bearing 811, and the first bearing 811 is connected to the mounting plate 5 by a first shoulder screw 8111. The end of the second connecting rod 82 away from the first connecting rod 81 is connected to the second bearing 821, and the second bearing 821 is connected to the movable plate 6 by a second shoulder screw 8211.
[0020] The drive assembly 3 includes a motor 31 and a reducer 32. The reducer 32 is mounted on the frame 1. The output shaft of the motor 31 is connected to the input end of the reducer 32, and the output end of the reducer 32 is connected to the swing arm 2.
[0021] The swing arm 2 is connected to a guide rail 22, and two sliders 221 are slidably arranged on the guide rail 22. The two sliders 221 are symmetrically arranged on the guide rail 22, and the sliders 221 are connected to the movable plate 6. The movable plate 6 slides with the guide rail 22 on the swing arm 2 through the first slider 221, so that the movement trajectory is precise, avoiding deviation or jamming during the spacing adjustment process, and ensuring the consistency of the spacing adjustment of the two gripping components 7.
[0022] The clamping assembly 7 includes a lifting cylinder 71, a connecting frame 72, a thumb cylinder 73, and a clamping plate 74. The lifting cylinder 71 is vertically mounted on the movable plate 6. The connecting frame 72 is connected to the piston rod of the lifting cylinder 71. The thumb cylinder 73 is connected to the connecting frame 72. The clamping plate 74 is connected to one of the two movable seats of the thumb cylinder 73. The clamping plate 74 has a contoured groove adapted to the bottom of the impeller.
[0023] A guide block 721 is connected to the connecting frame 72, and a guide groove adapted to the guide block 721 is opened on the side wall of the lifting cylinder 71. Through the cooperation of the guide block 721 and the guide groove, the stability of the thumb cylinder 73 in lifting up and down is further improved.
[0024] The implementation principle of a dual-station variable-pitch clamping and transferring mechanism for impeller production and processing according to an embodiment of this application is as follows: Step 1: Initial State Preparation The mechanism is in standby mode, and the swing arm 2 is stopped at the corresponding transfer station of the next process conveyor line. The distance between the two gripping components 7 is consistent with the placement distance of the impeller of the next process conveyor line. The piston rod of the lifting cylinder 71 retracts, and the connecting frame 72 and the thumb cylinder 73 are in a high position; the two clamping plates 74 of the thumb cylinder 73 are in an open state, the contour groove faces the direction to be placed, and the guide block 721 is embedded in the guide groove of the lifting cylinder 71 to ensure accurate initial position. The positioning synchronous wheel 111 is fixed to the stationary fixed plate 11, the synchronous belt 4 is tensioned between the positioning synchronous wheel 111 and the bearing synchronous wheel 211, the adjustable connecting piece 8 is in the initial state, and the two movable plates 6 are symmetrically distributed at both ends of the guide rail 22 through the first slider 221.
[0025] Step 2: Swing arm 2 rotates forward and the spacing automatically shrinks. After the previous process conveyor line transports the two impeller workpieces to the designated clamping station, it sends a workpiece arrival signal to the mechanism. When the motor 31 starts, the power is reduced by the reducer 32 and output, which drives the swing arm 2 to rotate 90° in the positive direction around the axis of the positioning synchronous wheel 111. The clamping component 7 moves synchronously with the swing arm 2 to the next process conveyor line. Since the positioning synchronous wheel 111 is fixed, during the rotation of the swing arm 2, the tensioned synchronous belt 4 drives the bearing synchronous wheel 211 to rotate synchronously in the forward direction by 90°. The bearing synchronous wheel 211 drives the mounting plate 5 to rotate. The mounting plate 5 pulls the two movable plates 6 closer to each other along the guide rail 22 through two relatively set adjustable connecting pieces 8. After the swing arm 2 rotates 90° in the forward direction, it stops precisely above the preceding conveyor line. At this time, the distance between the two gripping components 7 is exactly matched with the distance between the two impeller workpieces of the preceding conveyor line, and the clamping plate 74 of each gripping component 7 is directly above the corresponding impeller.
[0026] Step 3, Gripping component 7 action The piston rod of the lifting cylinder 71 extends, driving the connecting frame 72, thumb cylinder 73 and clamping plate 74 to move downward. During the movement, the guide block 721 on the connecting frame 72 slides along the guide groove of the lifting cylinder 71 to ensure accurate descent trajectory and avoid deviation. When the thumb cylinder 73 is activated, the two movable seats drive the clamping plates 74 to clamp each other. Stable clamping is achieved through the contact action between the contour groove and the bottom of the impeller, ensuring that the workpiece does not shake or fall off. After clamping is completed, the piston rod of the lifting cylinder 71 retracts, driving the clamping plate 74 holding the impeller to return to its original position and detach from the material tray of the preceding conveyor line, preparing for subsequent transfer.
[0027] Step 4: Reverse rotation of swing arm 2 and automatic spacing reset. After the gripping component 7 rises and resets, the motor 31 drives the swing arm 2 to rotate 90° in the opposite direction around the axis of the positioning synchronous wheel 111, and the gripping component 7 moves with the swing arm 2 to the subsequent conveyor line. Similarly, the positioning synchronous wheel 111 remains stationary, the synchronous belt 4 drives the bearing synchronous wheel 211 to rotate 90° in the opposite direction, the mounting plate 5 pushes the two movable plates 6 away from each other along the guide rail 22 through the adjustable connector 8, and the spacing of the clamping components 7 is gradually reset to be consistent with the impeller placement spacing of the subsequent conveyor line. After the swing arm 2 rotates 90° in the opposite direction, it stops precisely above the subsequent conveyor line, and the two gripping components 7 are respectively facing the two placement stations of the subsequent conveyor line.
[0028] Step 5: Placement of the workpiece The piston rod of the lifting cylinder 71 extends again, causing the clamping plate 74 holding the impeller to move downward, accurately placing the impeller at the designated position on the subsequent conveyor line; After the impeller is placed stably, the thumb cylinder 73 is activated, the two clamping plates 74 open in opposite directions and detach from the impeller surface, the piston rod of the lifting cylinder 71 retracts, and drives the clamping plates 74 to return to the initial high position.
[0029] Finally, it should be noted that the above description is only a preferred embodiment of this utility model, and the protection scope of this utility model is not limited to the above embodiments. All technical solutions within the scope of this utility model's concept are within the protection scope of this utility model. It should be pointed out that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
