Detailed description of the invention
For the benefit of structure of the present utility model is understood, be described below in conjunction with drawings and Examples.
The utility model with dynamic knife machining mechanism structure as shown in Figure 2,3, described rocking arm 1 is in L-type, the end of the long-armed and galianconism of L-type rocking arm 1 is provided with the first follower 1 and the 3rd follower 10 separately, the corner of L-type rocking arm 1 is connected with mounting seat 8 by rotating shaft 9, can realize the swing in the height centered by rotating shaft 9; Fixed support 6 is arranged on by screw forges a knife on the cylinder body of cylinder 7, and mounting seat 8 is fixedly connected with cylinder 7 of forging a knife; Back-moving spring 4 and lead limit switch 5 are arranged on fixed support 6, and the long-armed connection of spring hook and L-type rocking arm 1 is passed through in one end of back-moving spring 4; L-type rocking arm 1 long-armed on be also provided with a protuberance, described protuberance is provided with the top that the second follower 3, second follower 3 is positioned at cylinder 7 push rod of forging a knife, and the contact of lead limit switch 5 is positioned at the side of the second follower 3.
The mode of forging a knife of the utility model knife machining mechanism can be divided into two kinds, manually forges a knife and automatic forging.
Particularly, as shown in Figure 4, manually forge a knife is control to forge a knife the motion up and down of push rod of cylinder 7 by magnetic valve, when push rod up moves, promotion second follower 3 moves upward by the nut on push rod, the swing that L-type rocking arm 1 can do back and forth centered by rotating shaft 9, main shaft is forged a knife ring 17 toward pressing down by the 3rd follower 10 simultaneously, thus achieves the action of manually forging a knife of main shaft 14.
Particularly, as shown in Fig. 5,6,7, the operating principle of automatic forging: tool arm motor 19 rotating band moving knife arm 11 rotates, and cam disc 5 is connected with cam box 12 by chain 16, and tool arm 11 is linked by the first follower 2 of the long-armed end of cam box 12, chain 16, wheel disc 5 and L-type rocking arm 1; When tool arm 11 turns to position (tool arm 11 is positioned at position concentric immediately below main shaft 14) as shown in Figure 7, cam disc 5 synchronous axial system is to maximum cylindrical place, the galianconism of L-type rocking arm 1 is toward pressing down, thus make the 3rd follower 10 main shaft be forged a knife ring 17 toward pressing down, achieve the action of forging a knife of main shaft 14.Rotate in the process of tool changing with dynamic i.e. tool arm 11 of forging a knife, the cam box 12 strap cam dish 5 that simultaneously operate rotates, and the galianconism of L-type rocking arm 1 is past to be pressed down main shaft ring 17 of forging a knife and realize main shaft and forge a knife, and this process is synchronously carried out, therefore tool-changing speed is fast.
Particularly, the adjustment of the amount of forging a knife is as shown in Fig. 3, Fig. 8, the effect of the amount of forging a knife repair sheet 20 is equivalent to adjust pad, pad, between mounting seat 8 and main spindle box 13, adjusts L-type rocking arm 1 by the height value h of the match grinding amount of forging a knife repair sheet 20 and main shaft is forged a knife ring 17 toward the amount (this value is the amount of forging a knife of main shaft) pressed down.
Below embodiment has been described in detail the utility model by reference to the accompanying drawings, and those skilled in the art can make many variations example to the utility model according to the above description.Thus, some details in embodiment should not formed restriction of the present utility model, the utility model by the scope that defines using appended claims as protection domain.
