Description

Technical Field

[0001] This utility model belongs to the field of CNC machine tool technology, and specifically relates to a positioning device for CNC machine tools. Background Technology

[0002] During the machining process of CNC machine tools, it is usually necessary to position various workpieces. Existing positioning mechanisms typically use clamping to hold and fix the ring-shaped workpiece to prevent it from shaking during drilling. However, in actual use, the following problems exist: the model of the clamp is generally fixed, but the model and size of the ring-shaped workpiece are undetermined. When the size of the ring-shaped workpiece is smaller than the clamping angle of the clamp, the ring-shaped workpiece cannot effectively fit against the surface of the clamp. This makes it easy for the ring-shaped workpiece to shake during drilling, causing trouble for the operator. To address these issues, we propose a positioning device for CNC machine tools. Utility Model Content

[0003] The purpose of this invention is to provide a positioning device for a CNC machine tool, which has the advantage of being able to clamp ring-shaped workpieces of different sizes, thereby improving the stability of drilling holes in the ring-shaped workpieces.

Detailed Implementation

[0019] The present invention will be further described in detail below with reference to the accompanying drawings.

[0020] Example 1: refer to Figure 1 , 2 and Figure 4 A positioning device for a CNC machine tool includes a fixed base 1 and a placement base 8. Fixed blocks 9 are welded to both sides of the placement base 8. A fixed plate 7 is bolted to one side of the fixed block 9. An electric push rod 5 is bolted to the center of one side of the fixed plate 7. A push plate 6 is bolted to one side of the electric push rod 5. A C-shaped limiting ring 4 is welded to the side of the push plate 6. Screw holes 18 are provided on both sides of the surface of the C-shaped limiting ring 4. A first bolt 11 is threaded into the inner cavity of the screw holes 18. A first bearing 12 is rotatably connected to one side of the first bolt 11. A limiting pad 13 is welded to the side of the first bearing 12. By using the screw holes 18 on both sides of the C-shaped limiting ring 4 in conjunction with the first bolt 11, the clamping distance of the limiting pad 13 can be adjusted to accommodate ring-shaped workpieces of different outer diameters, avoiding wobbling caused by size differences.

[0021] Furthermore, mounting blocks are welded to both sides of the fixing base 1, and mounting bolts are provided on the surface of the mounting blocks. The mounting blocks and mounting holes facilitate the assembly and disassembly of the fixing base 1.

[0022] Furthermore, a second nut 10 is welded to one side of the first bolt 11. The surface of the second nut 10 is provided with anti-slip stripes, which improve the stability of the second nut 10 in use.

[0023] Example 2: refer to Figure 1-4 A positioning device for a CNC machine tool includes a second bearing 16 welded to the bottom of the inner cavity of a fixed seat 1. A rotating rod 3 is rotatably connected to the inner cavity of the second bearing 16. The top of the rotating rod 3 is bolted to the bottom of a placement seat 8. The angle of the placement seat 8 can be easily adjusted through the second bearing 16 and the rotating rod 3. The drilling angle of the annular workpiece can be adjusted by the spacing, thereby improving the efficiency of processing the annular workpiece.

[0024] Furthermore, a nut 14 is welded to one side of the inner cavity of the fixed seat 1, and a second bolt 15 is threaded into the inner cavity of the nut 14. A first nut 2 is welded to the outer side of the second bolt 15. The nut 14 and the second bolt 15 facilitate the limiting and fixing of the rotating rod 3, preventing the rotating rod 3 from shaking during the stationary process, and improving the stability of drilling the ring workpiece.

[0025] Furthermore, a limiting hole 17 is provided on the surface of the rotating rod 3, and the inner side of the second bolt 15 is inserted into the inner cavity of the limiting hole 17. The limiting hole 17 facilitates the insertion of the second bolt 15.

[0026] Brief description of usage: The user places the annular workpiece on the surface of the placement seat 8. Then, the user starts the electric push rod 5 through the external controller. The electric push rod 5 pushes the push plate 6 to move, which in turn pushes the C-shaped limit ring 4 to move. The C-shaped limit ring 4 moves to fit against the outer surface of the annular workpiece. When the annular workpiece cannot fit against the surface of the C-shaped limit ring 4, the user turns the second screw cap 10 clockwise. The second screw cap 10 drives the first bolt 11 to rotate in the inner cavity of the screw hole 18. Since the threads on the surface of the first bolt 11 and the threads in the inner cavity of the screw hole 18 are threadedly connected, the rotation of the first bolt 11 allows it to move. For example, when the first bolt 11 rotates clockwise, it moves inward; conversely, when the first bolt 11 rotates counterclockwise, it moves outward. The clockwise and inward movement of the first bolt 11 pushes the first bearing 12 and the limit pad 13 to move. The rotating rod 3 moves to fit the surface of the annular workpiece, facilitating its positioning and fixation. When drilling holes in other locations on the surface of the annular workpiece, the user turns the first screw cap 2 in reverse. Since the threads on the surface of the first screw cap 2 and the threads in the inner cavity of the nut 14 are connected, when the first screw cap 2 reverses, it moves outward and disengages from the inner cavity of the limiting hole 17. At this time, the limiting pressure of the rotating rod 3 is eliminated. The user then turns the placement seat 8, which in turn drives the rotating rod 3 to rotate in the inner cavity of the second bearing 16. Simultaneously, the placement seat 8 drives the annular workpiece placed on the surface to rotate, effectively adjusting the angle position of the annular workpiece. After the angle position of the annular workpiece is adjusted, the user turns the second bolt 15 clockwise. The clockwise rotation of the second bolt 15 moves the rotating rod 3 into the inner cavity of the limiting hole 17, facilitating its positioning and fixation and improving the stability of drilling the annular workpiece.

[0027] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.
