[0029] refer to Figure 1 、 Figure 3 and Figure 4 As shown, the dust storage assembly 5 is arranged on the inner side of the support plate 1, and the dust storage assembly 5 includes a through groove 51, a shielding cover 52 and a placement groove 53.

[0035] The working principle of the quantitative cutting device for internal combustion engine valve steel bars provided by the utility model is as follows:

[0036] When in use, the connecting plate 45 and the positioning plate 7 are driven to move inside the limit groove 43 by the positioning rod 44 and adjusted to the required position according to the scale line 42. Under the action of the nut 6, the positioning rod 44 is fixed, and then the position of the connecting plate 45 and the positioning plate 7 is determined. The distance length between the cutter 20 and the first fixed frame 3 is fixed and unchanged. By adjusting the position of the connecting plate 45 and the positioning plate 7, quantitative cutting is convenient, and there is no need for manual length measurement. The valve steel rod body 12 is placed on the two second clamping blocks 11 through the placement groove 53 and placed against the positioning plate 7. The two threaded rods 9 are rotated respectively so that the threaded rod 9 drives the first clamping block 10 to move downward, clamping and limiting the valve steel rod body 12. Under the drive, the connecting rod 18 drives the adjustment plate 19 to move, so that the adjustment block 22 rotates under the support of the support frame 21, thereby facilitating the adjustment of the position of the cutter 20 and cutting the valve steel rod body 12 inside the shielding cover 52. The flying chips generated during cutting are blocked by the shielding cover 52 and fall into the storage box 54 for centralized storage, effectively avoiding the accumulation of chips and impurities on the support plate 1. After the cutting is completed, under the action of the handle 8, under the limit of the connecting plate 45, the positioning plate 7 is pulled upward to facilitate the removal of the cut valve steel rod body 12. When the limit of the bolt 16 is loosened, the control plate 15 is pulled to rotate under the support of the fixing frame 14, so that the cover 55 is opened, which is convenient for cleaning the chips and impurities in the storage box 54.
