The model of the second servo motor 11 can be BMH0701P06A2A, and the bottom of the storage board 12 near the side of the second servo motor 11 is equipped with a bottom plate 10 through a hinge. , and the top of the bottom plate 10 is installed on the side away from the second servo motor 11 with a limit block 6 , and the adjustment structure 5 is arranged inside the bottom plate 10 .

[0028] The bottom end of the base plate 10 is provided with a base plate 9, and a PLC controller 7 is installed on one end of t...

Embodiment 2

[0032] Embodiment 2: The adjustment structure 5 is composed of a support plate 501, a firmware block 502, a first servo motor 503, a screw 504, and a threaded sleeve 505. The screw 504 is horizontally arranged inside the bottom plate 10 through a bearing, and the outer wall of the screw 504 is provided with a screw thread. sleeve 505, and the top of the threaded sleeve 505 runs through the top of the bottom plate 10 and is equipped with a support plate 501 through a hinge, and a firmware block 502 is installed at the bottom of the storage plate 12 near the limit block 6, and the other end of the support plate 501 is hinged The first servo motor 503 is installed on the side of the bottom plate 10 close to the limit block 6, and the output end of the first servo motor 503 is connected to the screw rod 504 through the rotating shaft.

[0033] The bottom of the threaded sleeve 505 is slidingly connected to the bottom inside the base plate 10 , and the length of the support plate 50...

Embodiment 3

[0035] Embodiment 3: movable structure 8 is made up of supporting block 801, movable block 802, auxiliary block 803 and pneumatic telescopic rod 804, and pneumatic telescopic rod 804 is arranged on the side away from PLC controller 7 inside substrate 9, and the output of pneumatic telescopic rod 804 A movable block 802 is installed at the end, and a support block 801 is installed on the top of the movable block 802, and auxiliary blocks 803 are installed at the four corners of the bottom of the bottom plate 10;

[0036] The top of the supporting block 801 is connected to the bottom of the base plate 10 , and the movable block 802 and the auxiliary block 803 are both slidingly connected to the base plate 9 .

[0037] Specifically, as figure 1 and image 3 As shown, the PLC controller 7 controls the opening of the pneumatic telescopic rod 804. The model of the pneumatic telescopic rod 804 can be BC21-A, so that the pneumatic telescopic rod 804 drives the support block 801 to mo...

Abstract

The invention discloses a fixing fixture for milling machining, and relates to the technical field of milling production and machining equipment. The fixing fixture comprises a base plate, a bottom plate and a storage plate, a second servo motor is mounted in the center of one side of the storage plate, the bottom plate is mounted on the side, close to the second servo motor, of the bottom end of the storage plate through a hinge piece, a limiting block is mounted on the side, away from the second servo motor, of the top end of the bottom plate, an adjusting structure is arranged in the bottom plate, the base plate is arranged at the bottom end of the bottom plate, a PLC is mounted on the side, close to the limiting block, of one end of the base plate, a movable structure is arranged in the base plate, and a bidirectional threaded rod is transversely mounted in the storage plate through a bearing. A rotating plate is driven by a clamping plate to move to clamp a workpiece, then a rotating head is rotated to drive the rotating plate to rotate, after the rotating plate reaches a proper position, a clamping rod is inserted into a clamping groove to fix the rotating head, and therefore the workpiece can be rotated and overturned.

Description

technical field [0001] The invention relates to the technical field of milling production and processing equipment, in particular to a fixed fixture for milling. Background technique [0002] Milling is to fix the blank workpiece, and use a high-speed rotating milling cutter to move on the blank to cut out the required shape and features. During the cutting process, the blank workpiece needs to be fixed to prevent shaking, but the traditional processing fixture cannot hold the workpiece Flip, when processing the back of the workpiece, the workpiece needs to be turned over and fixed again. [0003] After searching, the Chinese Patent Authorization Announcement No. CN209439818U, announced on September 27, 2019, announced a milling processing fixture. It is proposed in the article that "the X-axis clamping assembly includes an X-axis double-helix lead screw set on the base. , the first moving piece and the second moving piece arranged on the X-axis double screw screw, the firs...
