[0032] The working principle of the novel needle seat device is as follows:

[0033] The first step: when the needle holder body 2 needs to be adjusted in position first after being fixed, the second threaded column 8 is rotated, so that the second threaded column 8 drives the second sliding block 7 to move back and forth, that is, drives the needle holder body 2 to move back and forth, so that the position adjustment effect of the needle holder body 2 is achieved; at this time, the first threaded column 5 is rotated, so that the first threaded column 5 drives the first sliding block 4 to move horizontally, that is, drives the sliding seat 6 to move horizontally, and then drives the needle holder body 2 to move horizontally, so that the horizontal position adjustment effect of the needle holder body 2 is achieved, and then the adjustment effect of the fixed position of the needle is achieved, and then the convenience of position adjustment after positioning and fixing is brought; when the sliding seat 6 moves horizontally, the limiting groove 3 limits the horizontal movement of the first sliding block 4, so that the problem of position deviation of the first sliding block 4 during horizontal movement is avoided, so that the stability of the first sliding block 4 during horizontal movement is improved, that is, the stability of the needle holder body 2 during movement is improved; when the sliding seat 6 moves horizontally, the sliding ball 9 supports and limits the horizontal movement of the sliding seat 6, so that the problem of friction between the sliding seat 6 and the top of the base 1 during horizontal movement is avoided, so that the smoothness of the sliding seat 6 during horizontal movement is improved;

[0034] The second step: when the first threaded column 5 drives the first sliding block 4 to move horizontally, the shock-absorbing plate 10 limits and protects the first sliding block 4, so that the problem of impact between the first sliding block 4 and the inner wall of the limiting groove 3 during rapid movement is avoided, so that the needle holder body 2 is not vibrated violently, so that the protection effect of the needle holder body 2 during movement is achieved; when the needle holder body 2 needs to be installed and fixed, the first bolt 112 is rotated, so that the first bolt 112 drives the fixed seat 111 to be tightly extruded and fixed on the top of the second sliding block 7, that is, the needle holder body 2 is extruded and fixed on the top of the sliding seat 6, so that the installation and fixing effect of the needle holder body 2 is achieved; when the needle holder device needs to be installed and fixed, the second bolt 122 is rotated, so that the second bolt 122 fixes the support frame 121 on the machine tool table top; at this time, the support frame 121 supports and fixes the base 1, so that the installation and fixing of the needle holder body 2 are achieved, and the convenience of installation and fixing of the needle holder device is brought.

[0035] Compared with the related art, the novel needle holder device has the following beneficial effects:

[0036] When the needle holder body 2 needs to be adjusted in position after being fixed, the second threaded column 8 is rotated, so that the second threaded column 8 drives the second sliding block 7 to move back and forth, i.e. drives the needle holder body 2 to move back and forth, thereby achieving the position adjustment effect of the needle holder body 2. At this time, the first threaded column 5 is rotated, so that the first threaded column 5 drives the first sliding block 4 to move horizontally, i.e. drives the sliding seat 6 to move horizontally, and then drives the needle holder body 2 to move horizontally, thereby achieving the horizontal position adjustment effect of the needle holder body 2, and then achieving the adjustment effect of the fixed position of the needle, and then bringing convenience for the position adjustment after being fixed and positioned.
