Abstract
Description
Technical Field
[0001] This utility model relates to the field of new energy vehicle motor technology, and in particular to a core clamping device. Background Technology
[0002] With the rapid development of new energy electric vehicles, the electric drive system, as one of the "three electrics" (battery, motor, and electronic control), plays a crucial role in new energy electric vehicles. It is not only related to acceleration performance but also closely related to noise and vehicle stability. It is a key component.
[0003] Currently, most mainstream pure electric vehicles worldwide use either permanent magnet synchronous motors or AC induction (asynchronous) motors. Permanent magnet synchronous motors are the mainstream of the two. Permanent magnet synchronous motors use permanent magnets to provide excitation, which makes the motor structure simpler, reduces processing and assembly costs, and eliminates the slip rings and brushes that are prone to problems, thus improving the reliability of motor operation.
[0004] Different permanent magnet synchronous motors have different rotor cores, such as one-piece, two-layer, and four-layer, which need to be stacked in sequence during production. Manual stacking is slow and prone to errors. Utility Model Content
[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a core clamping device that can realize the rapid stacking of cores, maximize the realization of automated and intelligent production mode, reduce manual operation, liberate workers from busy and heavy work, improve production efficiency, and the fully automatic production cycle is only 50 seconds, which can meet the requirements of mass production.
[0006] The objective of this utility model is achieved through the following technical solution:
[0007] A core clamping device, comprising:
[0008] The clamping mechanism and the pressing mechanism are provided. The output end of the pressing mechanism is located in the clamping space of the clamping mechanism. An anti-drop mechanism is also provided on the outside of the clamping mechanism to prevent the iron core clamped on the clamping mechanism from falling accidentally.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0025] In this embodiment, as Figures 1 to 7 As shown, a core clamping device includes a clamping mechanism and a pressing mechanism. The output end of the pressing mechanism is located within the clamping space of the clamping mechanism. An anti-drop mechanism is also provided on the outside of the clamping mechanism to prevent the core clamped on the clamping mechanism from accidentally falling off. The moving directions of the clamping mechanism and the anti-drop mechanism are on the same horizontal line.
[0026] The clamping mechanism includes a fixed plate 1, which serves as the basic mounting component of the entire clamping mechanism, supporting and fixing other components. A gripper cylinder 2 is bolted to the underside of the fixed plate 1. The gripper cylinder 2 provides power to drive the movement of its output component. Two opposing sliding seats 3 are fixed to the output end of the gripper cylinder 2, allowing relative movement under the action of the gripper cylinder 2. A clamping seat 4 is welded to the underside of the sliding seat 3, and a clamping block 5 is screwed to the inner side of the clamping seat 4. The clamping block 5 directly contacts the iron core for clamping. Specifically, a trapezoidal groove is formed on the inner side of the clamping block 5. This groove is designed to fit the shape of the iron core, increasing the contact area and friction between the clamping block 5 and the iron core, thereby improving the stability and reliability of the clamping.
[0027] The clamping mechanism includes two supports 6 bolted to the lower side of the fixed plate 1. The supports 6 support and fix the clamping cylinders 7. The lower side of each support 6 is bolted to the clamping cylinder 7, and the output ends of both clamping cylinders 7 face downwards and are bolted to the same clamping plate 8. A gripper cylinder 2 is located between the two supports 6; this arrangement makes the structure compact and reasonable. When the clamping mechanism grips the iron core, the clamping cylinder 7 operates, pushing the clamping plate 8 downwards to clamp the iron core, further ensuring the stability of the iron core during handling and preventing the iron core from shaking or shifting.
[0028] The anti-fall mechanism includes a cylinder seat 9 bolted to the lower side of the sliding seat 3. The cylinder seat 9 is used to mount and fix the anti-fall cylinder 10. The anti-fall cylinder 10 is bolted to the cylinder seat 9, and the output end of the anti-fall cylinder 10 passes through the cylinder seat 9 and is bolted to an anti-fall seat 11. The anti-fall seat 11 is located outside the clamping seat 4, and the bent end of the bottom of the anti-fall seat 11 is located below the clamping seat 4. At the same time, a linear slide rail is fixed to the lower side of the sliding seat 3, and a slider is slidably mounted on the linear slide rail. The anti-fall seat 11 is fixed to the lower side of the slider. The cooperation between the linear slide rail and the slider can ensure that the anti-fall seat 11 slides stably in the horizontal direction. In addition, a rectangular opening is provided on the clamping seat 4. The rectangular opening and the clamping block 5 form a groove. The groove is adapted to the anti-fall seat 11. When the anti-fall cylinder 10 pushes the anti-fall seat 11 to move, the anti-fall seat 11 can be embedded in the groove of the clamping seat 4 to form a reliable blocking structure. After the clamping mechanism clamps the iron core, the anti-fall cylinder 10 operates, pushing the anti-fall seat 11 to move towards the clamping seat 4, so that the bent end of the anti-fall seat 11 is located below the iron core. Even if the clamping mechanism is accidentally loosened, the iron core will not fall, which greatly improves the safety of the device.
[0029] The structure of the anti-fall seat 11 is an integrally formed structure. The upper end of the anti-fall seat 11 forms an upper bending end and a lower bending end, respectively. The bending directions of the upper bending end and the lower bending end are opposite, and the bending angle of both is ninety degrees.
[0030] The clamping plate 8 has an integrally formed structure. The middle part of the clamping plate 8 is a circular structure with both ends extending outwards. The output end of the clamping cylinder 7 is fixed to the upper side of the extended end.
[0031] The fixed plate 1 is also fixed with a compensation unit, which is an outsourced component and is existing technology. The compensation unit is used for compensation and adjustment between the robot and the gripper to adapt to the small movements and deformations of the workpiece in the XY direction, ensuring that the workpiece will not move due to deformation during the gripping process, thereby improving production efficiency and product quality.
[0032] Working principle of this utility model:
[0033] First, the gripper cylinder 2 operates, driving the two sliding seats 3 to move relative to each other, which in turn causes the clamping seat 4 and clamping block 5 to clamp the iron core. Then, the pressing cylinder 7 is activated, pushing the pressing plate 8 downward to press the iron core. Finally, the anti-fall cylinder 10 is activated, pushing the anti-fall seat 11 to move to the predetermined position to prevent the iron core from falling. When it is necessary to release the iron core, the cylinders are operated in reverse order.
