[0022] The present invention will be described in detail below with reference to the accompanying drawings:

[0023] As shown in Figure 1, the auxiliary tooling fixture of a CNC machining center described in the utility model includes a clamping seat 1, and slide rails 2 are symmetrically fixedly installed on both sides of the interior of the clamping seat 1. The upper part of each slide rail 2 is slidably connected to a slider 3, and the upper part of each slider 3 is fixedly installed with a clamping plate 4. A threaded rod 5 is provided on the outer side of each clamping plate 4, and the threaded rod 5 is threadedly connected to the clamping seat 1. A handwheel 6 is fixedly installed on the outer end of each threaded rod 5, and the threaded rod 5 is connected to the clamping plate 4 with a bearing. A height bracket assembly 7 is installed in the middle part of the interior of the clamping seat 1.

[0024] In this embodiment, combined with the Figure 2 and attached Figure 3 As shown, the height bracket assembly 7 includes a linear motor 71, which adopts a bidirectional screw linear motor. A connecting piece 72 is fixedly installed in the middle of the linear motor 71, and both sides of the connecting piece 72 are pin-connected to the first rotating rod 73. The outer side of each of the first rotating rods 73 is cooperated with a second rotating rod 75, and the external pin of each group of the first rotating rod 73 away from the end of the connecting piece 72 and the end of the second rotating rod 75 is installed with a support block 74. The outer end of the second rotating rod 75 is also cooperated with a translation block assembly 8, which connects the linear motor 71 with the external control device. The linear motor 71 drives the translation block assembly 8 to move toward the middle. At this time, the second rotating rod 75 and the first rotating rod 73 support the support block 74, and the user uses the support block 74 to support the workpiece 9 and erect the workpiece 9 to a certain height according to the size of the workpiece 9 or the height at which the workpiece 9 needs to be placed. After fixing the workpiece 9 with the clamping plate 4, the support block 74 is lowered to prevent the support block 74 from affecting the processing of the workpiece 9.

[0025] In this embodiment, combined with the Figure 4 As shown, the translation block assembly 8 includes a translation connecting block 81, and U-shaped parts 82 are removably installed on both sides of the translation connecting block 81. A brush plate 83 is removably installed on the outer side of each U-shaped part 82. When the translation connecting block 81 moves, the brush plates 83 on both sides clean the upper part of the guide rail of the linear motor 71 to prevent the debris generated by the processing of the workpiece 9 from affecting the movement of the translation connecting block 81.

[0026] In this embodiment, specifically, the lower portions of the brush plates 83 provided on both sides of each translation connection block 81 are provided in contact with the translation connection block 81 .

[0027] In this embodiment, specifically, the lower end of each brush plate 83 is arranged to contact the upper surface of the linear motor 71 .

[0028] In this embodiment, specifically, the two translation connecting blocks 81 are fixedly mounted on the upper portion of the sliding ends on both sides of the linear motor 71 .

[0029] In this embodiment, specifically, the two translation connection blocks 81 are respectively connected to the outer end pins of the two second rotation rods 75 .

[0030] In this embodiment, specifically, the linear motor 71 is fixedly installed in the middle part of the clamping seat 1.

[0031] How it works

[0032] In the present invention, the user installs the clamping seat 1 on the lathe of the CNC machining center, and uses the height bracket assembly 7 to support the workpiece 9, so that the workpiece 9 is erected to a certain height. At this time, the threaded rod 5 is rotated by the handwheel 6, and the threaded rod 5 moves relative to the clamping seat 1, thereby driving the clamping plate 4 to move along the slide rail 2 through the slider 3, and the two clamping plates 4 move toward the middle, thereby clamping the workpiece 9.

[0033] Utilizing the technical solution described in the present invention, or those skilled in the art designing similar technical solutions inspired by the technical solution of the present invention to achieve the above-mentioned technical effects, all fall within the scope of protection of the present invention.
