[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0027] Refer to Figures 1 to 6 , an embodiment of the present invention provides a mechanical material clamping mechanism, which includes: a base 1, a moving seat 2, a plurality of material clamping seats 31 and a plurality of ejector rods 41. The moving seat 2 is arranged on the base 1, and a material clamping driver 20 capable of driving the moving seat 2 to move up and down relative to the base 1 is also arranged on the base 1; all the material clamping seats 31 are arranged side by side in the left-right direction at the lower part of the moving seat 2, and a material clamping groove 30 for inserting a workpiece is formed between adjacent material clamping seats 31. An elastic member capable of clamping the workpiece in the material clamping groove 30 is arranged on the material clamping seat 31; the ejector rods 41 are arranged on the moving seat 2, and the lower end of each ejector rod 41 faces a material clamping groove 30 and can eject the workpiece located in the material clamping groove 30 downward. An ejecting driver 40 capable of driving all the ejector rods 41 to move up and down relative to the moving seat 2 together is also arranged on the moving seat 2. The ejecting driver 40 is preferably a cylinder.

[0028] Refer to Figure 7 And Figure 8 , one use of the present invention is to grab a plurality of insulating shells 7 placed in a row, and then under the drive of an external driving device, the present invention and the grabbed insulating shells 7 are moved together above a row of stator cores 6 or a row of stator cores 6 are moved below the present invention. Finally, all the insulating shells 7 are ejected downward together, so that the insulating shells 7 are sleeved on the stator cores 6 one by one.

[0029] The process of clamping the insulating shell 7 is as follows: First, a row of insulating shells 7 are conveyed below the present invention, and the insulating shells 7 are positioned by other mechanisms. The positioned insulating shells 7 are located below the corresponding material clamping grooves 30. Then the material clamping driver 20 works to drive the moving seat 2 to move downward, so that the insulating shells 7 are inserted into the corresponding material clamping grooves. At this time, the elastic member deforms to clamp the insulating shells 7, and then the material clamping driver 20 drives the moving seat 2 to move upward, that is, the work of clamping the insulating shell 7 is completed. The process of ejecting the insulating shell 7 is as follows: First, the material clamping driver 20 drives the moving seat 2 and the ejector rods 41 on the moving seat 2 to move downward a certain distance. After the moving seat 2 reaches the predetermined position, the ejecting driver 40 works to drive the ejector rods 41 to extend into the corresponding material clamping grooves 30, and eject the insulating shells 7 from the material clamping grooves 30 and sleeve them on the corresponding stator cores 6.

[0030] As a preferred embodiment of the present invention, the elastic member is a spring plate 32 provided on the side of the clamping seat 31. Both ends of the spring plate 32 are connected to the clamping seat 31. The portion between the two end portions of the spring plate 32 is a deformation portion 321, and the deformation portion 321 is arc-shaped and bulges away from the clamping seat 31 to which it is connected. In each clamping groove 30, generally two spring plates 32 are provided, and the two spring plates 32 are respectively installed on the clamping seats 31 on both sides of the clamping groove 30; of course, only one spring plate 32 can also be provided. For example, the left side of the clamping groove 30 has a spring plate 32, and there is no spring plate 32 on the right side.

[0031] Referring to Figure 3 With Figure 6 , a longitudinal limiting groove 311 is provided on the side wall of the clamping seat 31. Both ends of the deformation portion 321 are embedded in the limiting groove 311, and the middle portion of the deformation portion 321 extends out from the opening of the limiting groove 311. Such a structure can limit the spring plate 32, so that the spring plate 32 can only generate elastic deformation in the left-right direction. In addition, the maximum stroke of the spring plate 32 is also limited, avoiding that defective products with larger volume excessively squeeze the spring plate 32 to cause the spring plate 32 to fail.

[0032] A first clamping groove 312 is provided on the upper end surface of the clamping seat 31, and a second clamping groove 313 is provided on the lower end surface of the clamping seat 31. The upper end portion of the spring plate 32 is clamped in the first clamping groove 312, and the lower end portion of the spring plate 32 is clamped in the second clamping groove 313.

[0033] In some embodiments of the present invention, the above-mentioned elastic member can also adopt other structural forms. For example, an arc-shaped plate is used to replace the deformation portion 321 of the spring plate 32, and a spring is connected between the arc-shaped plate and the clamping seat 31; or an elastic colloid is directly used to replace the above-mentioned spring plate 32.

[0034] Referring to Figure 1 With Figure 2 , in this embodiment, a motor seat 11 is provided on the upper part of the base 1. The clamping driver 20 includes a motor provided on the motor seat 11, and the output end of the motor is connected to the moving seat 2 through a lead screw pair 5. A cylinder seat 21 is provided on the upper part of the moving seat 2. The ejecting driver 40 includes a cylinder provided on the cylinder seat 21, and the output end of the cylinder is connected to a ejector rod mounting plate 42, and all the ejector rods 41 are installed at the bottom of the ejector rod mounting plate 42.

[0035] In some embodiments of the present invention, the clamping driver 20 can also adopt devices such as a cylinder, and the ejecting driver 40 can also adopt devices such as a motor.

[0036] Furthermore, the moving seat 2 is arranged on the base 1 through a vertically guiding rail mechanism; the ejector rod mounting plate 42 is arranged on the moving seat 2 through a vertically guiding rail mechanism.

[0037] The above is only the preferred implementation mode of the present invention. As long as the technical solutions that achieve the purpose of the present invention by basically the same means fall within the protection scope of the present invention.
