Among them, the fixture plays the role of fixing the workpiece.

[0003] In the prior art, the arrangement of the fixtures is relatively simple. For example, the fixtures are usually arranged to fix the workpiece laterally (along the horizontal direction of the CNC machine tool worktable), and the tool on the CNC machine tool further processes the side end of the workpiece.

[0004] However, when the fixed workpiece is thin or irregular in shape, its own surface to be processed is hidden by the fixture. At this time, it is necessary to move the tool or re-fix the workpiece to adapt to the working conditions of the fixed workpiece. The process is relatively cumbersome. The existing fixture limits the fixing direction of the workpiece, which not only reduces the fixing efficiency of the workpiece, but also narrows the scope of application of the CNC machine tool.

At this time, the support plate 81 is placed under the plate body 4; Step 3: When the plate body 4 and the clamp chuck 6 thereon are required to be in a horizontal state When in the vertical state, the staff first takes out the support plate 81, and then rotates the clamping plate 51 to make the clamping plate 51 disengage from the through slot 42. At this time, rotate the plate body 4 clockwise, lift another bolt 52 to make another clamping plate 51 pass through another through slot 42, and then rotate the other clamping plate 51 so that it is clamped on the top of the other through slot 42 compared to the description in step one; step four: the staff pushes the support plate 81 horizontally from the sides of the L-shaped plate body 2 and the plate body 4 into the first limit groove 82 and the second limit groove 83.

It should be noted that the specific area is determined according to the specific working conditions of the actual CNC machine tool. It is a prior art and will not be described in detail here. The device can fix the fixing plate 1 to a specific area of ​​the CNC machine tool by passing screws, bolts, etc. through the through holes 11 in the prior art, or directly weld the fixing plate 1 to a specific area of ​​the CNC machine tool.

[0039] When the plate body 4 is required to be in a horizontal state, that is, when the fixture chuck 6 is in a horizontal state, the staff moves the plate body 4 so that it is in a horizontal state, referring to Figure 3 As shown, at this time, the clamping plate 51 extends into the through slot 42, and the staff lifts the bolt 52 from the bottom of the bolt 52. After the clamping plate 51 completely passes through the through slot 42, the clamping plate 51 is rotated so that it is clamped at the top of the through slot 42. The staff then picks up the support plate 81 and pushes it horizontally into the first limit slot 82 and the second limit slot 83 from the side of the L-shaped plate body 2 and the plate body 4, thereby completing the horizontal state locking of the clamp chuck 6 in this device.

[0040] When the plate 4 is required to be in a vertical state, refer to Figure 1 and Figure 2 As shown, the staff moves the plate body 4 clockwise to make it in a vertical state.

[0041] The device, through the arrangement of the L-shaped plate 2, the roller 3 and the plate 4, utilizes the plate 4 being located at the intersection of the top surface and the side surface of the L-shaped plate 2, and cooperates with the use of the fixing component 5 and the support plate 81, so that the horizontal or vertical state of the plate 4 can be flexibly switched and firmly locked. The device also utilizes the arrangement of the support plate 81, the first limiting groove 82 and the second limiting groove 83, so that the support plate 81, the L-shaped plate 2 and the plate 4 can quickly form a stable triangle when the plate 4 is in a vertical or horizontal state, thereby improving the stability of the plate 4. The device also utilizes the fixing component 5 and the support plate 81, so that the support plate 81, the L-shaped plate 2 and the plate 4 can quickly form a stable triangle when the plate 4 is in a vertical or horizontal state, thereby improving the stability of the plate 4. The arrangement of the component 5 ensures that when the card plate 51 is fixing the plate body 4, the staff only needs to rotate the card plate 51 so that the card plate 51 extends into the through slot 42, and then the staff lifts the bolt 52 from the bottom of the bolt 52, and after the card plate 51 completely passes through the through slot 42, the card plate 51 is rotated so that it is stuck in the top of the through slot 42, wherein the card plate 51 is located in the slot body 41 and rotates to complete the fixation of the plate body 4, and at the same time, the support plate 81 is used to support the other side of the plate body 4 to complete the fixation and stabilization of the plate body 4 in a horizontal or vertical state.
