[0052] Some embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. In the case of no conflict, the embodiments described below and the features in the embodiments can be combined with each other.
[0053] As shown in FIG. 1, some embodiments provide a numerical control positioning device for silicon steel sheet, which comprises: Figures 1 to 4 A base 1 is arranged on a workpiece clamping table of a numerical control lathe, and the base 1 is horizontally arranged. Two positioning mechanisms 2 are oppositely arranged on the base 1, and the two positioning mechanisms 2 are suitable for pressing and positioning the workpiece from both sides. The positioning mechanism 2 comprises a positioning block 20 which is vertically arranged on the base 1. The distance between the two positioning blocks 20 is not less than the width of the workpiece, that is, when the workpiece is horizontally placed on the base 1, the distance between the two sides of the workpiece in the width direction and the positioning blocks 20 is provided with a distance. A buffer plate 3 is vertically arranged on the side wall of the positioning block 20, and the buffer plate 3 is parallel to the base 1. The positioning mechanism 2 drives the buffer plate 3 to move downward and abut against the workpiece, and the positioning block 20 continues to move downward. The buffer plate 3 is suitable for moving upward relative to the positioning block 20. Through the arrangement of the buffer plate 3, when the positioning mechanism 2 drives the positioning block 20 to move downward to clamp and position the workpiece, the buffer plate 3 can reduce the extrusion force of the positioning block 20 on the workpiece, thereby avoiding damage to the surface of the workpiece during clamping and positioning.
[0054] Reference is made to FIG. 2, which shows the working principle of the numerical control positioning device for silicon steel sheet. The base 1 is arranged on the workpiece clamping table of the numerical control lathe, and the base 1 is horizontally arranged. Two positioning mechanisms 2 are oppositely arranged on the base 1, and the two positioning mechanisms 2 are suitable for pressing and positioning the workpiece from both sides. The positioning mechanism 2 comprises a positioning block 20 which is vertically arranged on the base 1. The distance between the two positioning blocks 20 is not less than the width of the workpiece, that is, when the workpiece is horizontally placed on the base 1, the distance between the two sides of the workpiece in the width direction and the positioning blocks 20 is provided with a distance. A buffer plate 3 is vertically arranged on the side wall of the positioning block 20, and the buffer plate 3 is parallel to the base 1. The positioning mechanism 2 drives the buffer plate 3 to move downward and abut against the workpiece, and the positioning block 20 continues to move downward. The buffer plate 3 is suitable for moving upward relative to the positioning block 20. Through the arrangement of the buffer plate 3, when the positioning mechanism 2 drives the positioning block 20 to move downward to clamp and position the workpiece, the buffer plate 3 can reduce the extrusion force of the positioning block 20 on the workpiece, thereby avoiding damage to the surface of the workpiece during clamping and positioning.
[0055] Figure 2 The positioning mechanism 2 comprises: a driving cylinder 21 vertically arranged on the base 1; a lifting column 22 arranged at both ends of the piston rod of the driving cylinder 21 and the positioning block 20 respectively; the lifting column 22 penetrates the upper surface of the base 1; a limiting plate 23 vertically arranged on the side wall of the positioning block 20 and arranged above the buffer plate 3. The limiting plate 23 is arranged above the base 1, when the workpiece is horizontally placed on the base 1, the limiting plate 23 is above the workpiece, when the driving cylinder 21 drives the limiting plate 23 to vertically move downward, the limiting plate 23 is suitable for driving the buffer plate 3 to synchronously move downward until the buffer plate 3 abuts against the workpiece, with the limiting plate 23 continuing to move downward, the buffer plate 3 keeps stationary relative to the workpiece, at this time, the limiting plate 23 applies a pushing force to the buffer plate 3 through each compression spring 30 to improve the extrusion force of the buffer plate 3 on the workpiece, preventing the workpiece from moving or shaking during cutting. The compression spring 30 and the buffer plate 3 can also avoid leaving marks or local deformation on the workpiece due to excessive pressure applied by the limiting plate 23.

A plurality of telescopic columns 31 are arranged between the buffer plate 3 and the limiting plate 23, and the compression spring 30 is sleeved on the outer wall of the telescopic column 31. The compression spring 30 and the telescopic column 31 can drive the buffer plate 3 to synchronously move upward when the limiting plate 23 moves upward, and the telescopic column 31 can prevent the buffer plate 3 from shaking relative to the limiting plate 23, thereby improving the accuracy of the extrusion and limiting of the limiting plate 23 on the workpiece.
[0057] With reference to the accompanying drawings Figure 3 A plurality of air outlets 201 are formed in the side wall of the positioning block 20, the air outlets 201 face the bottom wall of the buffer plate 3, the air outlets 201 are communicated with a compressed air pump, and the compressed air pump is suitable for conveying compressed air into the air outlets 201. When the workpiece is horizontally placed on the base 1, the compressed air is conveyed outward from the air outlets 201 to clean the impurities on the bottom wall of the buffer plate 3 and the surface of the workpiece. Before cutting, the workpiece is horizontally placed on the base 1, at this time, the compressed air is conveyed outward from the air outlets 201 to clean the impurities or debris remaining on the surface of the workpiece and the bottom wall of the buffer plate 3, thereby preventing the impurities or debris from remaining on the bottom wall of the buffer plate 3 during the process of the buffer plate 3 pressing the workpiece.
