Detailed Description

The technical solution in the embodiment of the present invention is clearly and completely described below with reference to the drawings in the embodiment of the present invention. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be implemented in other ways different from the specific details set forth herein, and one skilled in the art may similarly generalize the present invention without departing from the spirit of the present invention, and therefore the present invention is not limited to the specific embodiments disclosed below.

As shown in fig. 1 to 3, the present invention provides a jig for a milling machine, which comprises a mounting plate 10, a fixing block 20 and a clamping member 30;

the fixed block 20 is arranged at the front end of the mounting plate 10, and a plurality of arc-shaped openings 21 with uniform intervals are formed in the inner end of the fixed block 20;

clamping piece 30 sets up the rear end at mounting panel 10, clamping piece 30 includes connecting plate 31, flexible post 32, movable plate 33, spring structure 34, connecting block 35 and driving piece 36, connecting plate 31 sets up the rear end at mounting panel 10, be provided with a plurality of even flexible posts 32 in interval on the connecting plate 10, a plurality of flexible posts 32 correspond one respectively arc opening 21, movable plate 33 is connected with flexible post 32's the inner, the both ends of movable plate 33 are provided with spring structure 34 respectively, spring structure 34's outer end is connected with the both ends of connecting block 35, connecting block 35 sets up the rear end tip at mounting panel 10, driving piece 36 sets up the middle part position at connecting block 35, driving piece 36 is used for driving movable plate 33 and removes.

Operation, install this anchor clamps on the workstation of milling machine, place a plurality of arc openings 21 respectively to a plurality of cylinders 5 afterwards, make movable plate 33 move to cylinder 5 direction through driving piece 36 afterwards, movable plate 33 moves, and make spring structure 34 extend, movable plate 33 drives a plurality of flexible posts 32 and moves to cylinder 5 direction respectively simultaneously, the outer end of a plurality of flexible posts 32 then can contact with cylinder 5 in a plurality of arc openings 21, and press from both sides a plurality of cylinders 5 simultaneously tightly in arc openings 21, and easy operation, also need not repeated change cylinder 5, the sequential messenger operating personnel is light more.

After the milling cutter finishes processing the cylinder 5 at the front end, the next cylinder 5 to be processed is moved to the lower part of the milling cutter for processing through the workbench capable of moving transversely and vertically.

In addition, the driving modes of the transverse movement and the vertical movement of the workbench on the milling machine are all completed by the driving of the screw rod, and the details are not described here because of the prior art.

Preferably, the mounting plate 10 is provided with mounting holes 11 at four corners thereof, respectively.

The jig is mounted to the table through mounting holes 11 at four corners of the mounting plate 10,

preferably, the inner ends of the telescopic columns 32 are respectively provided with a return spring 41, the end parts of the inner ends of the telescopic columns 32 are provided with a connecting disc 42, the inner ends of the connecting discs 42 are respectively provided with a spring 43, and the springs 43 are respectively connected with the moving plate 33.

When the moving plate 33 moves in the direction of the cylinder 5, the moving plate 33 moves the telescopic column 32 in the direction of the cylinder 5 via the spring 43 and the connecting disc 42, and the return spring contracts and clamps the cylinder 5 in the arc-shaped opening 21.

It should be noted that, since the sizes of the same size workpieces are not exactly the same, there is a certain tolerance, for example, when the diameters of the two cylinders are different by a few centimeters, and the telescopic columns corresponding to the two cylinders are stressed uniformly by the contraction of the spring, and are clamped at the same time.

Preferably, the driving member 36 is a screw 51, and a rotating column 52 is disposed on one end of the screw 51.

When the rotating column 52 is rotated manually, the screw 51 is rotated and moved toward the moving plate 33 to contact the moving plate 33, and the rotating column 52 is rotated manually, so that the screw 51 pushes the moving plate 33 to move toward the cylinder 5.

As shown in fig. 4, the clamp can also preferably clamp the square structure 7, and only the square structure 7 needs to be placed between the fixed block 20 and the connecting plate 31, and then the square structure 7 is clamped by moving the moving plate 33 with the telescopic column 32. This allows a small portion of the square to be clamped without the need to change the clamps used for the square 7 regularly.

It is obvious that the described embodiments are only some of the embodiments of the present invention, and not all of them. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
