Description

Technical Field

[0001] This utility model relates to the technical field of aluminum motor rotor processing equipment, specifically a clamping and positioning component. Background Technology

[0002] Cast aluminum motor rotor processing equipment is a mechanical device specifically designed for manufacturing cage-type cast aluminum rotors. Its core function is to inject molten aluminum into the rotor core slots through a casting process to form an integrated aluminum cage assembly with components such as guide bars, end rings, and fan blades. This type of equipment typically incorporates automation technology and covers key processes such as aluminum melting, die casting, cooling, and post-processing to ensure rotor quality and production efficiency.

[0003] The main process of aluminum casting motor rotor processing equipment is to first heat aluminum to a liquid state and then inject the molten aluminum into the groove-shaped cavity of the rotor core through a quantitative pouring or high-pressure injection system. Subsequently, centrifugal force (centrifugal casting) or high pressure (high-pressure casting) is used to ensure that the molten aluminum fills the groove evenly, reducing porosity and improving conductivity. After cooling and solidification, the rotor is demolded and then undergoes post-processing steps such as deburring, dimensional correction, and short-circuit testing to finally form a low-resistance, high-strength aluminum cage rotor. The equipment achieves efficient and stable large-scale production through precision molds, automated temperature control, and pressure regulation systems, and is especially suitable for high-performance demand scenarios such as new energy vehicle motors.

[0004] Existing aluminum casting motor rotor processing equipment injects molten aluminum into the groove-shaped cavity of the rotor core to ensure that the molten aluminum is evenly filled in the groove of the workpiece. Since the workpiece is located in the positioning groove on the conveyor belt, the equipment does not effectively limit the positioning groove at the bottom of the workpiece during the process of injecting molten aluminum, which may cause the positioning groove to shake and affect the effect of molten aluminum injection into the workpiece. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a clamping and positioning component to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a clamping and positioning assembly, comprising a device housing and a liquid injection assembly.

[0015] Preferably, the contact block can limit the movement of workpieces of different sizes within a certain range, thereby improving the practicality of the equipment.

[0016] The present invention is further configured such that the rack is L-shaped and the rack and the large gear mesh with each other.

[0017] Preferably, by using a rack, the movement of the injection component drives the rack to move downward, utilizing the kinetic energy of the downward movement of the injection component, thus reducing the energy consumption of the equipment.

[0018] The present invention is further configured such that a fixing rod is provided at one end of the large gear, and the other end of the fixing rod is connected to the inside of the device housing.

[0019] Preferably, the installation of a fixing rod improves the stability of the large gear during rotation, thereby enhancing the stability of the clamping assembly.

[0020] The present invention is further configured such that a limiting block is provided at the bottom of the injection component, and the limiting block is bolted to the injection component.

[0021] Preferably, the two sets of limiting blocks are threadedly connected to the liquid injection assembly, which facilitates the adjustment of the length of the applicable limiting blocks according to the size of the workpiece.

[0022] The present invention is further configured such that the number of limiting blocks is two sets, and the two sets of limiting blocks are installed on the top of the positioning groove.

[0023] Preferably, the limiting block limits both ends of the positioning groove, thereby improving the stability of the positioning groove during operation of the injection assembly.

[0025] Preferably, the positioning groove is limited at multiple angles to improve its stability, thereby improving the processing effect of the liquid injection component.

[0026] In summary, the present invention has the following main advantages:

[0027] 1. By setting up the clamping component, the contact block contacts the positioning groove during the process of the liquid injection component injecting aluminum liquid into the workpiece. This limits the position of the positioning groove, effectively improving the stability of the workpiece during processing, reducing the possible shaking of the positioning groove, and improving the liquid injection effect of the workpiece.

[0028] 2. This utility model uses a limiting block to limit the position of the positioning groove. The limiting block is set at the bottom of the injection component and contacts the outer wall of the positioning groove. When the fixing block limits the positioning groove, the limiting block also limits the position of the positioning groove, which further improves the stability of the positioning groove and reduces the shaking of the positioning groove during the operation of the injection component.

The large gear 41 and the small gear 42 are provided at one end of the rack 40, and a connecting rod 43 is installed at one end of the small gear 42. Multiple sets of contact blocks 44 are installed on the outer wall of the connecting rod 43. Through the setting of the clamping assembly 4, the device enables the liquid injection assembly 2 to perform... During the aluminum injection process, the contact block 44 contacts the positioning groove 5, limiting the position of the positioning groove 5. This effectively improves the stability of the workpiece during processing, reduces the possibility of shaking in the positioning groove 5, and improves the injection effect. By setting the limiting block 21, a limiting block 21 is set at the bottom of the injection assembly 2, and the limiting block 21 contacts the outer wall of the positioning groove 5. When the fixing block 45 limits the positioning groove 5, the limiting block 21 also limits the position of the positioning groove 5, further improving the stability of the positioning groove 5 and reducing the shaking of the positioning groove 5 during the operation of the injection assembly 2.

[0040] For details regarding the above embodiments, please refer to [link / reference]. Figures 2-4 The connecting rod 43 is provided with fixing blocks 45 at both ends, and the other end of the fixing block 45 is connected to the inner wall of the device housing 1. The setting of the fixing block 45 effectively improves the stability of the connecting rod 43 when rotating, thereby improving the stability of the displacement of the contact block 44.

[0041] For details regarding the above embodiments, please refer to [link / reference]. Figures 2-4 The outer wall of the connecting rod 43 is provided with an external thread, and a contact block 44 is sleeved on the outer wall of the external thread. Limiting rings 46 are provided at both ends of the contact block 44. The setting of the limiting rings 46 makes it easy to limit the position of the contact block 44, so that the distance between the two sets of contact blocks 44 can be adjusted.

[0042] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 , Figure 4 The limiting ring 46 is sleeved on the outer wall of the external thread and meshes with the external thread. One end of the limiting ring 46 is provided with an internal thread, which makes it easy for the limiting ring 46 to limit the position of the contact block 44 and reduce the shaking of the contact block 44.

[0043] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 , Figure 4 There are two sets of contact blocks 44. The set of contact blocks 44 near the pinion 42 is fixedly connected to the connecting rod 43, and the outer wall of the set of contact blocks 44 near the limiting ring 46 is also provided with external threads. The external threads mesh with the limiting ring 46, which makes it easy for the contact blocks 44 to limit the processing workpieces of different sizes within a certain range, thereby improving the practicality of the equipment.

[0044] For details regarding the above embodiments, please refer to [link / reference]. Figures 2-4 The rack 40 is L-shaped and meshes with the large gear 41. By setting the rack 40, the movement of the injection component 2 drives the rack 40 to move downward, utilizing the kinetic energy of the downward movement of the injection component 2, thus reducing the energy consumption of the equipment.

[0046] Second embodiment:

[0047] Please see Figure 5The difference between Embodiment 2 and Embodiment 1 is that, while retaining the features of Embodiment 1, a limiting block 21 is added to the bottom of the injection component 2 and the top of the positioning groove 5, so that the limiting block 21 limits the two ends of the positioning groove 5, thereby improving the stability of the positioning groove 5 during operation of the injection component 2.

[0048] Two sets of limiting blocks 21 are provided at one end of the injection component 2 near the positioning groove 5, and the two sets of limiting blocks 21 are threadedly connected to the injection component 2, so that the length of the applicable limiting blocks 21 can be adjusted according to the size of the workpiece. Secondly, a positioning groove 5 is provided in the middle of the limiting block 21, and the limiting block 21 contacts the outer wall of the positioning groove 5, which temporarily limits the position of the positioning groove 5, effectively improving the stability of the positioning groove 5 during operation of the injection component 2 and reducing the shaking of the positioning groove 5.

[0049] In practical operation, this utility model is as follows:

[0050] When it is necessary to inject liquid into the workpiece, first place the positioning groove 5 on the conveyor belt, and then place multiple sets of workpieces in the groove at the top of the positioning groove 5 in sequence. Then, by starting the control button of the equipment, the conveyor belt drives the workpiece to move. When the workpiece moves to the bottom of the liquid injection component 2, the liquid injection component 2 moves downward, and the liquid injection component 2 drives the positioning plate 20 to move downward in sync. One end of the positioning plate 20 is equipped with a rack 40, which causes the rack 40 to move downward, driving the large gear 41 and the small gear 42 to move. The small gear 42 drives the connecting rod 43 to rotate, causing the contact block 44 to flip, so that the contact block 44 contacts the outer wall of the positioning groove 5 to limit the position of the positioning groove 5, thereby limiting the position of the workpiece. Finally, the liquid injection component 2 injects liquid into the workpiece.

[0051] Furthermore, a limiting block 21 is installed at the bottom of the positioning plate 20 and at one end near the positioning groove 5. The limiting block 21 contacts the outer wall of the positioning groove 5 to limit the position of the positioning groove 5, thereby limiting the positioning groove 5 at multiple angles, improving the stability of the positioning groove 5, and thus improving the processing effect of the liquid injection component 2.

[0052] Furthermore, the outer wall of the connecting rod 43 is provided with contact blocks 44, and there are two sets of contact blocks 44. The set of contact blocks 44 near the pinion 42 is fixedly connected to the connecting rod 43, and the contact block 44 near the external thread of the outer wall of the connecting rod 43 is sleeved on the outer wall of the external thread. The limiting ring 46 is threadedly connected to the contact block 44 and the connecting rod 43 respectively, so that the limiting ring 46 limits the position of the contact block 44, which makes it easier for the contact block 44 to limit the processing of different sizes of workpieces within a certain range, thereby improving the practicality of the equipment.
