Description
Technical Field
[0001] This utility model relates to the technical field of toothed ring assembly, specifically an automatic assembly system based on a water pump toothed ring. Background Technology
[0002] In the assembly process of water pumps, the toothed ring, as one of the key components, is usually formed by bending a thin sheet material into an approximately elliptical structure with an opening. Due to its open nature, the toothed ring cannot form a complete circle in its natural state, and its theoretical outer diameter is generally designed to be about 2mm smaller than the inner diameter of the water pump front cover to facilitate assembly.
[0003] In an automated assembly line for water pumps, if a key process still requires manual intervention, it will disrupt the automation continuity of the entire line, necessitating the allocation of additional dedicated personnel, increasing labor costs, and restricting production pace.
[0004] In existing technologies, the assembly of the toothed ring generally relies on manual operation: the operator needs to manually press both sides of the toothed ring opening to temporarily close it before inserting it into the inner hole of the front cover; during this process, the two open ends of the toothed ring often overlap due to elastic rebound, requiring manual intervention again to pry them open and align them before the assembly can be completed. This results in the following disadvantages: the toothed ring relies on manual assembly, which easily wastes labor and time costs, makes it difficult to guarantee the assembly accuracy of the toothed ring, and reduces the consistency and stability of the toothed ring assembly. Utility Model Content
[0005] The purpose of this invention is to provide an automatic assembly system based on a water pump toothed ring, in order to solve the problems of toothed rings relying on manual assembly, which easily wastes labor and time costs, makes it difficult to guarantee the assembly accuracy of the toothed rings, and reduces the consistency and stability of toothed ring assembly.
[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: an automatic assembly system based on a water pump toothed ring, comprising a toothed ring feeding belt, a housing, a central control system, a frame, a toothed ring sorting and transfer mechanism, a transfer positioning mechanism, a toothed ring transfer mechanism, a product positioning mechanism, and a toothed ring assembly mechanism. The toothed ring feeding belt and the frame both extend into the housing. The central control system, the toothed ring sorting and transfer mechanism, the transfer positioning mechanism, the toothed ring transfer mechanism, and the toothed ring assembly mechanism are all disposed within the housing. The product positioning mechanism is slidably disposed on the frame. A plurality of toothed ring bodies are placed on the toothed ring feeding belt, and a plurality of belt line baffles are fixed on the toothed ring feeding belt. The toothed ring bodies are snapped onto the belt line baffles, and a positioning sensor is fixed on the toothed ring feeding belt.
[0007] Preferably, the toothed ring sorting and transplanting mechanism includes a mounting plate, which is fixed to the inner wall of the housing. An electric slide rail is fixed on the mounting plate, and a first gripper is fixed on the electric slide rail.
[0008] Preferably, the transfer positioning mechanism includes a mounting frame, which is fixed to the inner wall of the housing. Two telescopic cylinders are fixed to the bottom surface of the mounting frame. A positioning sleeve is fixed to one end of the telescopic rod of each telescopic cylinder, and the positioning sleeve is slidably connected inside the mounting frame.
[0009] Preferably, the toothed ring transplanting mechanism includes a load-bearing plate, which is fixed to the inner wall of the housing. Two guide rails are fixed to the top surface of the load-bearing plate, and two electric sliders are slidably connected to the guide rails. A sliding column is fixed to the load-bearing plate.
[0010] Preferably, the product positioning mechanism includes a positioning fixture, which is slidably mounted on a frame. A second gripper is fixed on the frame and corresponds to the positioning fixture. A lifting positioning mechanism is fixed on the inner bottom surface of the housing. One end of the telescopic rod of the lifting positioning mechanism is fixed to the positioning fixture. A front cover is provided on the positioning fixture, and the front cover is engaged with the toothed ring body.
[0011] Preferably, the toothed ring assembly mechanism includes a fixed plate, which is fixed to the top surface of the electric slider on the guide rail. The fixed plate is slidably connected to the sliding column. A pressing plate is provided below the fixed plate. Several limiting posts are fixed to the top surface of the pressing plate and inserted into the fixed plate. An assembly cylinder is fixed to the top surface of the fixed plate. One end of the telescopic rod of the assembly cylinder is fixed to the top surface of the pressing plate. A protective sleeve is fixed to the bottom surface of the pressing plate. Several connecting posts are fixed to the top surface of the pressing plate. A connecting plate is fixed to the top of the connecting posts. A pressing cylinder is fixed to the top surface of the connecting plate. A central pressing sleeve is fixed to one end of the telescopic rod of the pressing cylinder and corresponds to the toothed ring body.
[0012] Compared with existing technologies, an automatic assembly system based on a water pump toothed ring, which adopts the above technical solution, has the following advantages: I. Through the coordinated action of the toothed ring feeding belt, housing, central control system, frame, toothed ring sorting and transfer mechanism, transfer positioning mechanism, toothed ring transfer mechanism, product positioning mechanism, and toothed ring assembly mechanism, automatic assembly of the toothed ring body can be achieved, reducing manual intervention and effectively saving the labor and time costs wasted by manual assembly, thereby improving the assembly efficiency of the toothed ring body. Through the coordinated action of the electric slide rail and the first gripper, automated gripping and transfer of the toothed ring body can be achieved, replacing manual sorting and transfer operations, improving sorting and transfer efficiency, avoiding errors and inefficiencies caused by manual operation, and facilitating the automated connection of the toothed ring body from the toothed ring feeding belt to the transfer positioning mechanism. Second, the toothed ring body is clamped and positioned by a transfer positioning mechanism fixed by a mounting bracket. A telescopic cylinder drives the positioning sleeve to slide, achieving a corrective treatment of the open toothed ring body. This transforms the originally irregular, elliptical toothed ring body into an orderly state, preventing assembly difficulties caused by the irregular shape of the toothed ring body during manual assembly. The load-bearing plate of the toothed ring transfer mechanism provides a stable installation base, allowing the guide rail and electric slider to cooperate for smooth sliding during the transfer. The sliding column limits the sliding stroke, preventing over-transfer or offset. This achieves automated and precise transfer of the toothed ring body from the transfer positioning mechanism to the assembly station, replacing manual handling, improving transfer efficiency and positioning accuracy, and ensuring the continuity of the assembly process. Third, the positioning fixture of the product positioning mechanism can be slidably set on the frame. Combined with the lifting and positioning functions of the top-mounting positioning mechanism, it can quickly and accurately position the positioning fixture carrying the front cover to the assembly station. The second gripper then clamps and positions the front cover, ensuring it remains fixed during assembly and preventing displacement. This guarantees precise alignment between the toothed ring body and the front cover, preventing the inaccuracies and inefficiencies of manual front cover positioning and ensuring accurate assembly of the toothed ring body. The assembly cylinder drives the pressing plate to descend, achieving initial assembly by inserting the lower part of the toothed ring body into the front cover. Then, the pressing cylinder drives the central pressing sleeve to press down, completing the secondary assembly by pressing the entire toothed ring body into the bottom of the front cover. This two-stage pressing and positioning, along with the cooperation of the protective sleeve, limiting posts, and other components, ensures the stability of the pressing and lowering process, preventing deformation or displacement of the toothed ring body during assembly. This replaces manual pressing and pushing assembly methods, preventing problems such as overlapping openings and incomplete assembly during manual assembly, significantly improving assembly accuracy and efficiency.

[0019] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0020] like Figures 1-5 As shown, an automatic assembly system based on a water pump toothed ring includes a toothed ring feeding belt 1, a housing 2, a central control system 201, a frame 3, a toothed ring sorting and transferring mechanism 4, a transfer and positioning mechanism 5, a toothed ring transferring mechanism 6, a product positioning mechanism 7, and a toothed ring assembly mechanism 8. The toothed ring feeding belt 1 and the frame 3 both extend into the housing 2. The central control system 201, the toothed ring sorting and transferring mechanism 4, the transfer and positioning mechanism 5, the toothed ring transferring mechanism 6, and the toothed ring assembly mechanism 8 are all housed within the housing 2. The product positioning mechanism 7... The toothed ring is slidably mounted on the frame 3. Several toothed ring bodies 101 are placed on the toothed ring feeding belt 1. Several belt baffles 102 are fixed on the toothed ring feeding belt 1. The toothed ring bodies 101 are snapped onto the belt baffles 102. A position sensor 103 is fixed on the toothed ring feeding belt 1. The toothed ring sorting and transfer mechanism 4 includes a mounting plate 401, which is fixed to the inner wall of the housing 2. An electric slide rail 402 is fixed on the mounting plate 401, and a first gripper 403 is fixed on the electric slide rail 402.
[0021] In use, when it is necessary to assemble the toothed ring body 101, the operator can first place a batch of toothed ring bodies 101 on the toothed ring feeding belt 1, so that the opening direction of the toothed ring body 101 is engaged with the belt baffle 102 to ensure stable posture during feeding. When the toothed ring body 101 is conveyed to the end housing 2 by the toothed ring feeding belt 1, the position sensor 103 detects the product signal and feeds it back to the central control system 201. The central control system 201 controls the toothed ring feeding belt 1 to stop running, completing the feeding and positioning. Subsequently, the central control system 201 commands the toothed ring sorting and transfer mechanism 4 to start. Its first gripper 403 grabs the toothed ring body 101 positioned on the toothed ring feeding belt 1 and transfers it to the transfer positioning mechanism 5 through a preset trajectory. After the toothed ring body 101 is placed at the center of the transfer positioning mechanism 5, the two side positioning sleeves 503 clamp the toothed ring body 101 under the action of the telescopic cylinder 502. On the one hand, it achieves precise positioning, and on the other hand, it corrects the toothed ring body 101, which was originally open elliptical, so that its shape is regular and ready for subsequent assembly. After receiving the signal from the central control system 201, the toothed ring transfer mechanism 6 and the toothed ring assembly mechanism 8 move to the top of the transfer positioning mechanism 5 through the toothed ring transfer mechanism 6. The toothed ring assembly mechanism 8 descends and grabs the corrected toothed ring body 101. Then the toothed ring transfer mechanism 6 drives the toothed ring assembly mechanism 8 to move to the top of the positioning fixture 701, waiting for the assembly station to be ready. After the positioning fixture 701 is loaded with the front cover 704 and transported to the assembly station, the central control system 201 controls the lifting and positioning mechanism 703 to start, lifting the positioning fixture 701 and achieving precise positioning. At the same time, the second gripper 702 of the product positioning mechanism 7 extends to clamp and fix the front cover 704 in the center position to prevent the front cover 704 from shifting during the assembly process. Under the control of the central control system 201, the toothed ring assembly mechanism 8 presses down, first inserting the lower part of the toothed ring body 101 into the front cover 704 to achieve preliminary assembly. Then, the protective sleeve 805 of the toothed ring assembly mechanism 8 opens synchronously, and the central pressing sleeve 809 applies downward pressure under the drive of the pressing cylinder 808, pressing the toothed ring body 101 into the bottom of the front cover 704 to complete the final assembly. After the assembly is completed, each mechanism rises and resets, and the positioning fixture 701 is transported away from the assembly station. The system repeats the above process and enters the next assembly cycle. Through the coordinated action of the toothed ring feeding belt 1, housing 2, central control system 201, frame 3, toothed ring sorting and transfer mechanism 4, transfer positioning mechanism 5, toothed ring transfer mechanism 6, product positioning mechanism 7, and toothed ring assembly mechanism 8, the automatic assembly of the toothed ring body 101 can be achieved, reducing manual intervention and effectively saving the labor and time costs wasted by manual assembly, thereby improving the assembly efficiency of the toothed ring body 101. Through the coordinated action of the electric slide rail 402 and the first gripper 403, the automated gripping and transfer of the toothed ring body 101 can be achieved, replacing manual sorting and transfer operations, improving sorting and transfer efficiency, avoiding errors and inefficiencies caused by manual operation, and facilitating the automated connection of the toothed ring body 101 from the toothed ring feeding belt 1 to the transfer positioning mechanism 5.
[0022] like Figures 1-5 As shown, the transfer positioning mechanism 5 includes a mounting frame 501, which is fixed to the inner wall of the housing 2. Two telescopic cylinders 502 are fixed to the bottom surface of the mounting frame 501. A positioning sleeve 503 is fixed to one end of the telescopic rod of the telescopic cylinder 502. The positioning sleeve 503 is slidably connected inside the mounting frame 501. The toothed ring transplanting mechanism 6 includes a load-bearing plate 601, which is fixed to the inner wall of the housing 2. Two guide rails 602 are fixed to the top surface of the load-bearing plate 601. Two electric sliders are slidably connected to the guide rails 602. A sliding column 603 is fixed to the load-bearing plate 601.
[0023] In use, the toothed ring body 101 is fixed by the transfer positioning mechanism 5 via the mounting bracket 501. The telescopic cylinder 502 drives the positioning sleeve 503 to slide, which clamps and positions the toothed ring body 101, achieving the straightening treatment of the open toothed ring body 101. This straightens the originally irregular open elliptical toothed ring body 101 into an orderly state, preventing assembly difficulties caused by the irregular shape of the toothed ring body 101 during manual assembly. The load-bearing plate 601 of the toothed ring transfer mechanism 6 provides a stable installation base, allowing the guide rail 602 and the electric slider to achieve smooth sliding of the transfer action. The sliding column 603 limits the sliding stroke, avoiding over-transfer or offset. This realizes the automated and precise transfer of the toothed ring body 101 from the transfer positioning mechanism 5 to the assembly station, replacing manual handling, improving transfer efficiency and positioning accuracy, and ensuring the continuity of the assembly process.
[0024] like Figures 1-3 and Figure 5As shown, the product positioning mechanism 7 includes a positioning fixture 701, which is slidably mounted on the frame 3. A second gripper 702 is fixed on the frame 3, corresponding to the positioning fixture 701. A lifting positioning mechanism 703 is fixed to the inner bottom surface of the housing 2. One end of the telescopic rod of the lifting positioning mechanism 703 is fixed to the positioning fixture 701. A front cover 704 is provided on the positioning fixture 701, which is engaged with the toothed ring body 101. The toothed ring assembly mechanism 8 includes a fixing plate 801, which is fixed to the top surface of the electric slider on the guide rail 602. The fixing plate 801 is slidably connected to the sliding column 603. The lower part of the fixing plate 801... A pressing plate 802 is provided, and several limiting posts 803 are fixed on the top surface of the pressing plate 802. The limiting posts 803 are inserted into the fixing plate 801. An assembly cylinder 804 is fixed on the top surface of the fixing plate 801. One end of the telescopic rod of the assembly cylinder 804 is fixed to the top surface of the pressing plate 802. A protective sleeve 805 is fixed on the bottom surface of the pressing plate 802. Several connecting posts 806 are fixed on the top surface of the pressing plate 802. A connecting plate 807 is fixed at the top of the connecting posts 806. A pressing cylinder 808 is fixed on the top surface of the connecting plate 807. A central pressing sleeve 809 is fixed at one end of the telescopic rod of the pressing cylinder 808. The central pressing sleeve 809 corresponds to the toothed ring body 101.
[0025] In use, the positioning fixture 701 of the product positioning mechanism 7 can be slidably set on the frame 3. With the lifting and positioning functions of the lifting positioning mechanism 703, the positioning fixture 701 carrying the front cover 704 can be quickly and accurately positioned at the assembly station. Then, the second gripper 702 clamps and positions the front cover 704, ensuring that the front cover 704 remains fixed during the assembly process, avoiding displacement during assembly, ensuring accurate docking between the toothed ring body 101 and the front cover 704, preventing the problems of insufficient accuracy and low efficiency when manually positioning the front cover 704, and providing a guarantee for the accurate assembly of the toothed ring body 101. The assembly cylinder 804 drives the pressing plate 802 to descend, achieving the initial assembly of the toothed ring body 101 being inserted into the front cover 704. Then, the pressing cylinder 808 drives the central pressing sleeve 809 to press down, completing the secondary assembly of the toothed ring body 101 being pressed into the bottom of the front cover 704. This achieves two pressing and positioning operations, thus ensuring the stability of the pressing and lowering process with the cooperation of components such as the protective sleeve 805 and the limiting post 803. This prevents the toothed ring body 101 from deforming or shifting during assembly, replacing the manual pressing and pushing assembly method and preventing problems such as overlapping openings and incomplete assembly in manual assembly, thereby significantly improving assembly accuracy and efficiency.
[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
