DETAILED DESCRIPTION
[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] refer to Figure 1-2 As shown, the utility model provides a cemented carbide machine tool tool blank grinding device, comprising: a chuck 2, a blank body 10 and an ejector assembly 6 are sequentially arranged on the top, a plurality of supporting blocks 4 are sequentially arranged along the axial direction below the blank body 10, and a lifting mechanism connected to the bottom of the plurality of supporting blocks 4 is sequentially arranged on one side in the axial direction of the blank body 10, and the lifting mechanism is used to drive the supporting blocks 4 to perform lifting and lowering adjustment.
[0022] As mentioned above, when using the chuck 2, the blank body 10, the ejector assembly 6, the multiple support blocks 4 and the lifting mechanism provided by the utility model, the chuck 2 and the ejector assembly 6 are all prior arts, and therefore are not described in detail. One end of the blank body 10 is clamped on the chuck 2. During this process, according to the length of the blank body 10, multiple support blocks 4 of corresponding lengths are abutted against the bottom of the blank body 10 under the action of the lifting mechanism. When the blank body 10 is rotating, the blank body 10 is supported by the multiple support blocks 4 to prevent the blank body 10 from being deformed.
[0023] In the present utility model, combined with Figure 2 and Figure 4 As shown, the lifting mechanism of this embodiment includes a lifting block 7 and a lifting seat 9 which are arranged in sequence from top to bottom. The top of the lifting seat 9 is provided with a lifting hole 13 extending into the operating table 1. The bottom end of the lifting block 7 is at least partially lifted and extends into the lifting hole 13. The supporting block 4 is detachably mounted on one side of the top end of the lifting block 7. The lifting seat 9 is provided with a limit member for limiting the lifting of the lifting block 7.
[0024] Combination Figure 4 As shown, a spring 14 for elastically supporting the lifting block 7 is also installed in the lifting hole 13, and a guide member for longitudinally guiding the spring 14 is provided between the lifting block 7 and the lifting seat 9.
[0025] As described above, when using the lifting mechanism provided by the utility model, the lifting seat 9 in the lifting mechanism provides a lifting position for the lifting block 7. The lifting block 7 is lifted and lowered by the elastic force of the spring 14 and installed in the lifting hole 13 in the lifting seat 9. The elastic force of the spring 14 can assist the lifting block 7 in lifting and adjusting. During the adjustment process, the spring 14 is longitudinally guided by the guide member.

After the lifting block 7 is lifted and lowered on the lifting seat 9 through the lifting hole 13, the adjusting bolt 8 is tightened so that one end of the adjusting bolt 8 abuts against the lifting block 7, thereby limiting the lifting block 7 on the lifting seat 9 and preventing the lifting block 7 from lifting and lowering on the lifting seat 9.
[0027] Further, in order to prevent the lifting mechanism from interfering with the movement of the ejector assembly 6, refer to Figure 3 As shown, a mounting crossbeam 5 for supporting the support block 4 is also provided on one side of the top of the lifting block 7, and a threaded hole 15 extending into the support block 4 is penetrated through the mounting crossbeam 5, and a fastening bolt 3 screwed into the threaded hole 15 is provided below the mounting crossbeam 5. The mounting crossbeam 5 facilitates the installation of the lifting seat 9 in a direction away from the movement of the ejector assembly 6, so as to avoid the lifting seat 9 interfering with the movement of the ejector assembly 6, and the support block 4 can be detachably mounted on the mounting crossbeam 5 by the fastening bolt 3, so as to facilitate the replacement of the support block 4.
[0028] Further, in order to increase the service life of the spring 14, refer to Figure 4 As shown, the guide member includes a guide rod 12, the bottom end of which is longitudinally mounted inside the lifting hole 13, and a guide hole 11 for accommodating the guide rod 12 is provided at the bottom end of the lifting block 7, and a spring 14 is sleeved on the guide rod 12.
