DETAILED DESCRIPTION
[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.
[0021] Example 1
[0022] The utility model provides a die punch for precision machining, such as Figures 1 to 5 As shown, it includes a fixed block 1, a first fixed rod 3 is movably connected inside the fixed block 1, a threaded rod 4 is welded at one end of the first fixed rod 3, a second fixed rod 14 is movably connected inside one end of the first fixed rod 3, three positioning holes 15 are equidistantly provided inside the second fixed rod 14, a limiting plate 16 is welded on the top of one end of the second fixed rod 14, a second bolt 17 is movably connected inside the limiting plate 16, the second bolt 17 passes through the limiting plate 16 and is fixed at the position of the limiting groove 18 of the fixed block 1, a limiting groove 18 is provided on one end surface of the fixed block 1, a plane groove 19 is provided on one end surface of the first fixed rod 3, three guide holes 21 are equidistantly provided on the outside of the first fixed rod 3 at the position of the plane groove 19, one of the guide holes 21 is movably connected inside the third bolt 20, the third bolt 20 passes through the guide hole 21 and the positioning hole 15 inside the second fixed rod 14 and is fixed inside the first fixed rod 3, and a guide rail 13 is provided on the top of the outer surface of the first fixed rod 3.
[0023] like Figure 1 and Figure 4 As shown, the outer side of the threaded rod 4 is threadedly connected to a fixing sleeve 5, the inner side of the threaded rod 4 is sleeved with a limiting sleeve 6, a first positioning hole 8 is provided at the top of one end of the limiting sleeve 6, a punch 7 is clamped inside the limiting sleeve 6, a second positioning hole 9 is provided at the top of one end of the punch 7, and a first bolt 12 is movably connected to one end face of the punch 7. The threaded rod 4 is fixed by the fixing sleeve 5 on the outer side, thereby enhancing the stability of the structure.
[0024] like Figure 1 and Figure 5 As shown, the limiting plate 16 and the guide rail 13 have the same size, and the limiting plate 16 is movably connected to the inside of the guide rail 13. The cooperation between the limiting plate 16 and the guide rail 13 can adjust the position of the first fixing rod 3 as needed, thereby enhancing adaptability and flexibility.
[0025] like Figure 1 and Figure 4 As shown, the first positioning hole 8 and the second positioning hole 9 have the same size and are clamped with a positioning plate 10 inside. A fixing hole 11 is provided inside the positioning plate 10. The first bolt 12 passes through one end of the punch 7 and the fixing hole 11 inside the positioning plate 10 and is fixed to one end face of the punch 7. The cooperation between the positioning plate 10 and the first bolt 12 effectively prevents the punch 7 from being displaced, thereby ensuring the accuracy of the processing.
[0026] like Figure 1 and Figure 5 As shown, the width of the limiting plate 16 is the same as the width of the limiting groove 18. The combination of the limiting plate 16 and the limiting groove 18 prevents the first fixing rod 3 from being displaced in the vertical direction, thereby enhancing the stability of the overall structure.
[0027] like Figure 1 and Figure 5 As shown, the size of the guide hole 21 is equal to the size of the positioning hole 15 , ensuring that the third bolt 20 is accurately aligned in the guide hole 21 and the positioning hole 15 .
[0028] Working principle: During actual use of the device, the limiting plate 16 is slid, and the limiting plate 16 drives the second fixing rod 14 to slide. A suitable guide hole 21 is selected according to production requirements, and the third bolt 20 is passed through the guide hole 21 and the positioning hole 15 inside the second fixing rod 14 to be fixed inside the first fixing rod 3. At this time, the limiting plate 16 is inserted into the limiting groove 18, and then the second bolt 17 is passed through the limiting plate 16 to be fixed to the position of the limiting groove 18 of the fixing block 1. At this time, the position of the first fixing rod 3 is fixed, and the height or position of the fixing rod can be quickly adjusted according to processing requirements, thereby improving the applicability in different application scenarios, and can also prevent the fixing rod from moving when subjected to force, thereby increasing the stability of the fixing rod and ensuring processing accuracy.
[0029] Then, the punch 7 is inserted into the limiting sleeve 6. At this time, the positioning plate 10 enters the punch 7 along the first positioning hole 8 and the second positioning hole 9. Then, the first bolt 12 is used to make the first bolt 12 pass through the fixing hole 11 of the positioning plate 10 through the thread, so that the positioning plate 10 and the first bolt 12 are threadedly fixed. At this time, the punch 7 and the limiting sleeve 6 are fixed. Then, after the limiting sleeve 6 and the punch 7 are inserted into the threaded rod 4, the fixing sleeve 5 passes through the punch 7 and contacts the threaded rod 4, and the fixing sleeve 5 is screwed. At this time, the fixing sleeve 5 increases the strength of the outside of the threaded rod 4 and squeezes the threaded rod 4, so that the punch 7 is fixed for the second time, which increases the stability of the punch 7 and avoids the sliding of the punch 7 caused by the limiting sleeve 6 under force, thereby ensuring the accuracy of the processing process.
[0030] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
