[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. Example

[0024] Please see Figure 1-3 A multi-station wedge-shaped linkage fixture for a machining center, comprising:

[0025] Two mounting bases 1, each mounting base 1 has a mounting groove on one outer wall, and a mounting plate 2 is rotatably embedded inside each mounting groove. Each mounting plate 2 has two threaded holes on its outer wall, and a track rod 3 is threaded between each pair of threaded holes; and

[0026] The clamping mechanism 5 is mounted on two track rods 3 and is used for clamping the workpiece.

[0027] In this embodiment, the mounting base 1 is installed on the multi-station of the machining center and is used as a support for the clamping mechanism 5. The length of the track rod 3 and the number of clamping mechanisms 5 can be adjusted according to the usage of the multi-station of the machining center. The clamping mechanism 5 slides on the track rod 3 to facilitate adjustment of its position. The track rod 3 is threaded onto two mounting discs 2 for easy replacement. The mounting discs 2 rotate on the mounting base 1 to facilitate angle adjustment of the clamping mechanism 5 on the track rod 3, which facilitates linkage of the clamping mechanisms 5 on multiple stations and improves the utilization efficiency of the machining center.

[0028] Please refer to the specific details. Figure 1-2 As shown, each mounting plate 2 has a limit ring 4 fixedly connected to its outer wall, and a drive motor 6 is fixedly installed on one side of the outer wall of one of the mounting bases 1. The output end of the drive motor 6 is fixedly connected to the corresponding outer wall of the mounting plate 2.

[0029] In this embodiment, the installation stability of the mounting plate 2 is improved by the limiting ring 4 to prevent the mounting plate 2 from detaching from the mounting base 1. The drive motor 6 can easily drive one of the mounting plates 2 to rotate, thereby facilitating the angle adjustment of the clamping mechanism 5.

[0030] Please refer to the specific details. Figure 2-3 As shown, the clamping mechanism 5 includes a chuck 501, which is slidably sleeved between the outer surfaces of the two track rods 3, and two positioning bolts 502 are threaded into the outer wall of the chuck 501.

[0031] In this embodiment, the chuck 501 is slidably sleeved on the two track rods 3, which facilitates its position adjustment. The positioning bolt 502 facilitates its positioning and improves the stability of the clamping mechanism 5 during operation.

[0032] Please refer to the specific details. Figure 3 As shown, two wedge-shaped jaws 503 are movably embedded inside the chuck 501. A dovetail slider 504 is fixedly connected to one side of the outer wall of each wedge-shaped jaw 503. Dovetail grooves are correspondingly opened on both sides of the inner wall of the chuck 501.

[0033] In this embodiment, the two wedge-shaped jaws 503 slide inside the chuck 501. Since the inner wall of the chuck 501 is inclined, the two wedge-shaped jaws 503 will move closer or further apart when sliding, which facilitates the use of the clamping mechanism 5. The dovetail slider 504 and the dovetail groove cooperate to improve the smoothness of the movement of the wedge-shaped jaws 503 and improve the use effect of the clamping mechanism 5.

[0034] Please refer to the specific details. Figure 3 As shown, a cylinder 505 is fixedly installed on one side of the outer wall of the chuck 501. A push plate 506 is fixedly installed on the telescopic end of the cylinder 505. A limit groove is opened on one side of the outer wall of the push plate 506. Two limit sliders 507 are movably embedded in the limit groove, and each limit slider 507 is fixedly connected to the outer wall of the corresponding wedge-shaped gripper 503.

[0035] In this embodiment, the cylinder 505 facilitates the movement of the push plate 506. Since the limiting slider 507 on the wedge-shaped gripper 503 is located inside the limiting groove on the push plate 506, it is convenient to drive the limiting slider 507 and the wedge-shaped gripper 503 to move, thereby improving the ease of use of the clamping mechanism 5.

[0036] Please refer to the specific details. Figure 3 As shown, each wedge-shaped gripper 503 has multiple anti-slip teeth 508 fixedly connected to one side of its outer wall.

[0037] In this embodiment, the anti-slip teeth 508 are used to improve the clamping effect of the wedge-shaped gripper 503.

[0038] Working principle: In use, the clamping mechanism 5 is installed on the track rod 3, and the track rod 3 is installed between the two mounting plates 2. The mounting base 1 is installed to the appropriate position of the machining center with bolts. The cylinder 505 is started, and the cylinder 505 drives the push plate 506 to move away from the cylinder 505, which drives the two wedge-shaped jaws 503 to move and move closer to each other to clamp the workpiece. When it is necessary to adjust the use angle of the clamping mechanism 5 at multiple stations, the drive motor 6 is started. The drive motor 6 drives one of the mounting plates 2 to rotate, which in turn drives the two track rods 3 to rotate, and drives multiple clamping mechanisms 5 to rotate synchronously, realizing the linkage of the clamping mechanisms 5 at multiple stations.

[0039] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
