Description

Technical Field

[0001] This utility model relates to the field of laser grooving technology, and in particular to a grooving device for silicon steel sheets. Background Technology

[0002] Electrical steel, also known as silicon steel sheet, is an essential soft magnetic alloy for the power, electronics, and military industries. Silicon steel sheets are divided into two types: non-oriented and grain-oriented. Grain-oriented silicon steel sheets are often used to manufacture rotor or stator components of high-voltage transformers and large generators. Reducing the iron loss of grain-oriented silicon steel sheets can effectively reduce the reactive power loss of transformers.

[0003] Currently, common methods to reduce iron loss in oriented silicon steel sheets include increasing the degree of grain aggregation and improving the grain structure. Among these, improving the grain structure requires scoring the silicon steel sheet to create a new type of coating with optimized tension. During scoring, the silicon steel sheet is first placed on a work platform, and then the operator clamps and fixes the silicon steel sheet. After fixing, the laser scoring machine is started to score the silicon steel sheet.

[0004] In the prior art, the silicon steel sheets are cut to different sizes according to process requirements. When the silicon steel sheets are placed on the work platform, the clamping mechanism cannot effectively clamp the silicon steel sheets of different sizes, which can easily cause the silicon steel sheets to loosen during grooving, thereby causing the silicon steel sheets to shift and affecting the grooving quality. Utility Model Content

[0005] Therefore, the technical problem to be solved by this utility model is to overcome the fact that the clamping mechanism in the prior art cannot effectively clamp silicon steel sheets of different sizes, which easily leads to the silicon steel sheets becoming loose during grooving, and thus causing the silicon steel sheets to shift and affecting the grooving quality.

The workpiece body 5 is placed on the machine body 1 within the clamping groove 8. During operation, before the silicon steel sheet is made into mechanical parts, it needs to be cut into squares of different sizes to facilitate the fabrication of different parts of the component. When the cut silicon steel sheet is placed on the machine body 1, the operator drives the drive disk 14 to rotate. When the drive disk 14 rotates, it can cause the four sets of upper gears 12 connected to the upper teeth 15 to rotate. The upper gears 12 are all bevel gears, all sleeved on the ball screw 11 and set on the drive disk 14. Above, a movable block 10 is connected to a ball nut on the ball screw 11. The ball nut is an assembly consisting of a ball nut, a steel ball, a circulating mechanism, and accessories. When the ball screw 11 rotates, it can drive the movable block 10 to move linearly on the ball screw 11. During linear motion, the silicon steel sheet workpiece body 5 can be clamped simultaneously by the clamping plate 6 above the movable block 10. Through the cooperation of the drive disk 14 and the upper gear 12, workpiece bodies 5 of different sizes can be clamped to avoid the workpiece body 5 from shifting when the clamping is not suitable.

[0025] In one embodiment of the present invention, a support column 20 is fixedly connected to the bottom of the inner body 1; the end of the support column 20 is rotatably connected to the drive disk 14. When working, the support column 20 is fixedly connected to the bottom of the inner body 1 to support the drive disk 14, and the top of the support column 20 is rotatably connected to the drive disk 14 to avoid the support column 20 affecting the operation of the drive disk 14.

[0026] In one embodiment of this utility model, a support block 23 is fixedly connected to the bottom of the machine body 1; a drive rod 22 is rotatably connected to the top of the support block 23; a through hole is opened on the side wall of the machine body 1; the drive rod 22 is disposed through the through hole; a drive gear 21 is fixedly connected to the end of the drive rod 22 away from the machine body 1; the drive gear 21 is meshed with the lower tooth 16. During operation, the operator can rotate the drive rod 22 and use the drive gear 21 at the end of the drive rod 22 to drive the drive disk 14 to rotate. The drive gear 21 is a bevel gear and meshes with the lower tooth 16 on the drive disk 14, thereby driving the clamping plate 6 to clamp the workpiece body 5.

[0027] In one embodiment of this utility model, a telescopic plate 19 is slidably connected in the clamping groove 8; four sets of telescopic plates 19 are provided. During operation, the telescopic plates 19 can prevent dust from entering the machine body 1 and affecting the internal mechanical transmission effect.

[0028] In one embodiment of this utility model, a rotating column 2 is rotatably connected to the top of the machine body 1; a bridge plate 3 is fixedly connected to the top of the rotating column 2; and a laser head 4 is fixedly connected to the bottom end of the bridge plate 3. During operation, after the workpiece body 5 is clamped, the rotating column 2 drives the laser head 4 on the bridge plate 3 to align with the workpiece body 5 to perform grooving.

[0029] In one embodiment of this utility model, a clamping pad 7 is provided on the clamping plate 6; the clamping pad 7 is made of rubber, and during operation, the clamping pad 7 can prevent the clamping plate 6 from slipping when clamping the workpiece body 5.

[0030] In one embodiment of this utility model, both the upper gear 12 and the drive gear 21 are bevel gears; a hand crank 24 is fixedly connected to one end of the drive rod 22 near the machine body 1. During operation, the operator can manually rotate the hand crank 24 to rotate the drive rod 22, thereby making the adjustment mechanism 27 operate. The bevel gear is a conical gear.

[0031] In one embodiment of the present invention, a support leg 25 is fixedly connected to the bottom of the body 1; a rubber pad 26 is fixedly connected to the bottom of the support leg 25. During operation, the body 1 may shake, and the support leg 25 can alleviate the shaking and the rubber pad 26 can prevent slippage during shaking.

[0032] Working Principle: To overcome the limitations of existing clamping mechanisms that cannot effectively clamp silicon steel sheets of different sizes, which can easily lead to loosening and displacement of the silicon steel sheets during grooving, thus affecting the grooving quality, the silicon steel sheets are first cut into squares of varying sizes before being manufactured into mechanical parts. This facilitates the fabrication of different parts within the component. When the cut silicon steel sheets are placed on the machine body 1, the operator drives the drive disk 14 to rotate. As the drive disk 14 rotates, it causes the four sets of upper gears 12, which are meshed by upper teeth 15, to rotate. All upper gears 12 are bevel teeth. All wheels are sleeved on the ball screw 11 and positioned above the drive disk 14. A ball nut connects to a moving block 10 on the ball screw 11. The ball nut is an assembly consisting of a ball nut, steel balls, a circulating mechanism, and accessories. When the ball screw 11 rotates, it can drive the moving block 10 to move linearly on the ball screw 11. During linear motion, the silicon steel sheet workpiece body 5 can be clamped simultaneously by the clamping plate 6 above the moving block 10. Through the cooperation of the drive disk 14 and the upper gear 12, workpiece bodies 5 of different sizes can be clamped, preventing the workpiece body 5 from shifting when the clamping is not suitable.

Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
