Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
As shown in fig. 1-2, the clamping mechanism for an edge milling machine of the present invention is applied to an edge milling machine.
An output shaft of the clamping motor 1 is connected with a first chain wheel 21 in the coupling 2 through a second speed reducer, a second chain wheel 22 in the coupling 2 is linked with the first chain wheel 21 through a double-row chain 23, the second chain wheel 22 is sleeved on a shaft sleeve 24, and a friction plate 25, a pressing plate 26 and an adjusting nut 27 are sequentially arranged on the shaft sleeve 24.
The pressure plate 26 is pressed by the adjusting nut 27 in cooperation with the threaded section of the sleeve 24 to press the friction plate 25 against the side end surface of the second sprocket 22.
The input shaft of the speed reducer 3 is connected with the shaft sleeve 24 so as to transmit the power of the clamping motor 1 to the speed reducer 3, a change shaft 31 and a second power input shaft 32 are arranged in the speed reducer 3, the change shaft 31 is connected with the input shaft of the speed reducer 3 in a vertical state, one end of the second power input shaft 32 is connected with the change shaft 31, and the other end extends out of the shell of the speed reducer 3 and is connected with a rocking handle mechanism 33.
A threaded sleeve 34 is arranged at the other end of the steering shaft 31, internal threads are arranged inside the threaded sleeve 34 and matched with the external threads on the steering shaft 31, and a supporting plate 35 is fixed at the top end of the threaded sleeve 34.
In practical application, the supporting plate 35 is fixed to the feeding platform 5 of the milling cutter, and the feeding platform 5 is disposed on the machine platform via the slide rail 51 and can move up and down. When the clamping motor 1 works, the steering shaft 31 rotates, and because the screw sleeve 34 and the supporting plate 35 are fixed with the feeding platform 5, the screw sleeve 34 cannot rotate along with the steering shaft 31, but can generate a pushing force under the action of the screw thread rotation force to lift the feeding platform 5.
The clamping platform 6 is arranged above the feeding platform 5, when the workpiece 100 abuts against the clamping platform 6, the workpiece 100 can be clamped, and then the milling cutter is started to mill the edge of the workpiece.
When the feeding platform 5 moves to a proper position (the workpiece 100 abuts against the clamping platform 6), the second chain wheel 22 in the coupler 2 and the friction plate 25 generate a slipping effect, so that the power input to the speed reducer 3 is disconnected, and an operator hears the slipping sound sent by the coupler 2, so that the power supply of the clamping motor 1 can be cut off, and the power output is stopped.
On the other hand, the second power input shaft 32 can be manually clamped by the crank mechanism 33, and when the electric clamping mode fails, the clamping can be performed in a manual mode.
The above description is only for the preferred embodiment of the present invention and should not be taken as limiting the invention, and any modifications, equivalent replacements and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
