Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-6 As shown, a clamping structure for a motor stator core includes: a processing table 1, a support mechanism 2 fixedly connected to the rear end face of the processing table 1, and two support mechanisms 2 are provided in a straight line array and fixedly connected to the left and right sides of the rear end face of the processing table 1.

[0026] Both support mechanisms 2 have longitudinally arranged support components 201 fixedly connected to their front ends. Hydraulic rods 2011 are mounted on the bottom ends of the support components 201, and pressure plate mechanisms 3 are fixedly connected to the bottom ends of the hydraulic rods 2011. The main body of the pressure plate mechanism 3 is circular. A servo motor 301 is fixedly connected to the top end of the pressure plate mechanism 3. A mounting base 3011 is mounted on the bottom output shaft of the servo motor 301. The mounting base 3011 has a rectangular cross-section. A ranging component 3012 is fixedly connected to the outside of the mounting base 3011. The ranging component 3012 is a laser ranging mechanism, and the ranging component 3012 has two... At the same location, two ranging components 3012 are fixedly connected to the left and right sides of the mounting base 3011 in opposite directions. An adjusting push rod 3013 is fixedly connected to the outer side of the mounting base 3011. There are two adjusting push rods 3013. The adjusting push rod 3013 is a cylinder structure. The two adjusting push rods 3013 are fixedly connected to the left and right sides of the mounting base 3011 in opposite directions. A clamping part 3014 is fixedly connected to the outer side of both adjusting push rods 3013. A chuck assembly 1014 is fixedly connected to the side of the moving component 1012 away from the clamping push rod 1011. The workpiece 1015 is clamped and limited inside the chuck assembly 1014.

[0027] Among them, a support leg assembly 101 is fixedly connected to the bottom surface of the processing table 1. The main body of the support leg assembly 101 is a rectangular frame structure. There are two support leg assemblies 101, which are fixedly connected to the left and right sides of the bottom surface of the processing table 1 respectively.

[0028] The processing table 1 and the support leg assembly 101 together form a support structure. A clamping push rod 1011 is fixedly connected inside the groove at the top of the processing table 1. There are two clamping push rods 1011. The two clamping push rods 1011 are fixedly connected to the left and right sides inside the processing table 1, respectively. A moving assembly 1012 is fixedly connected to the inner side of each of the two clamping push rods 1011. A sliding assembly 1013 is fixedly connected to the front and rear sides of the moving assembly 1012.

[0029] In use, firstly, the stator core to be clamped (i.e., workpiece 1015) is placed in the jaw assembly 1014, and the jaw assembly 1014 initially clamps and fixes it. At this time, the processing table 1 is stably supported by the support leg assembly 101 to ensure the stability of the entire device during operation. The clamping push rod 1011 is fixed on the left and right sides inside the processing table 1. The moving assembly 1012 connected to its inner side can move under the drive of the clamping push rod 1011. The sliding assembly 1013 on the front and rear sides of the moving assembly 1012 can assist the moving assembly 1012 to slide smoothly, so that the jaw assembly 1014 accurately positions the workpiece 1015 in the appropriate processing position.

[0030] The servo motor 301 at the top of the pressure plate mechanism 3 is started. The output shaft of the servo motor 301 drives the mounting base 3011 to rotate, so that the ranging component 3012 on the outside of the mounting base 3011 is in a suitable measuring position. Since the ranging component 3012 is a laser ranging mechanism and there are two opposite positions on the left and right sides of the mounting base 3011, it can measure the distance between it and the workpiece 1015. Based on the measured data, it is determined whether the position of the workpiece 1015 is accurate.

[0031] If the ranging component 3012 detects a deviation in the position of the workpiece 1015, the adjusting push rod 3013 on the outside of the mounting base 3011 starts to work. The adjusting push rod 3013 is a cylinder structure, and there are two opposing positions on the left and right sides of the mounting base 3011. The clamping part 3014 connected to its outside will adjust the position of the workpiece 1015 according to the deviation under the push of the adjusting push rod 3013. Through the synergistic action of the adjusting push rods 3013 on both sides, the workpiece 1015 can be accurately adjusted to the ideal clamping position, ensuring the positional accuracy of the workpiece 1015 before clamping.

[0032] After confirming that the position of workpiece 1015 is accurate, the hydraulic rod 2011 at the bottom of the support assembly 201 is activated. The hydraulic rod 2011 extends and pushes the pressure plate mechanism 3 downward to apply pressure to the workpiece 1015 located on the processing table 1, thereby realizing the clamping operation of the motor stator core. During the clamping process, the support mechanism 2 and the support assembly 201 provide stable support for the entire clamping action, ensuring that the clamping force can be evenly applied to the workpiece 1015.
