Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1-6: a set of rolling linear rails 6 which move linearly is arranged on the structure of the base body head library 7 and is fixedly connected with the two positioning pins 2 and the supporting seat 9 through the second connecting plate 8 and the first connecting plate 3. Meanwhile, the two positioning pins 2 are connected with a transition plate 12, and the transition plate 12 is connected with a guide shaft (a compression spring is arranged on the shaft) 11 and a fixed seat 10 and is limited and positioned by a limit block 13. The whole mechanism can move back and forth for a certain distance along the direction of the linear guide rail under the action of the spring force, and the position of the accessory milling head 1 is ensured to be unchanged after the accessory milling head is used and returns to the head warehouse.
The utility model is provided with a set of safer detection mechanisms, namely a limit switch 5 and a displacement sensor 4, which are used for detecting whether the accessory milling head 1 positioned and supported by the mechanical structure is safely and accurately put in place.
The supporting seat 9 is used for supporting the accessory milling head 1 to reach a one-surface two-pin positioning support, the one-surface two-pin positioning support is that the two positioning pins 2 limit the residual freedom degrees of the free body except the Z-axis direction in an over-positioning mode, and the one-surface two-pin positioning support can be used for auxiliary support, so that the accessory milling head can be stably and correctly placed.
The working principle of the utility model is as follows:
the attached figures 1-3 show a device for automatically replacing an accessory milling head, which comprises a base body head library 7, a set of rolling linear rail 6 which moves linearly, two positioning pins 2 and a supporting seat 9 which are fixedly connected and arranged on the rolling linear rail 6 which moves linearly through two connecting plates 8 and 3. Meanwhile, the two positioning pins 2 are connected with a transition plate 12, and the transition plate 12 is connected with a guide shaft (a compression spring is arranged on the shaft) 11 and a fixed seat 10 and is limited and positioned by a limit block 13. The whole mechanism can move back and forth for a certain distance along the direction of the linear guide rail under the action of the spring force, and the position of the accessory milling head is ensured to be unchanged after the accessory milling head is used and returns to the head warehouse. The limit switch 5 and the displacement sensor 4 are used for detecting whether the accessory milling head 1 positioned and supported by the mechanical structure is safely and accurately placed in place.
Fig. 4 shows that the ram provided with the accessory milling head 1 moves to a preset return position under the driving of the feeding mechanism of the machine tool.
In fig. 5, the clamping mechanism 15 in the ram 14 is released under hydraulic drive, and the pull stud 16 moves forward 9mm, so that the critical state that the end face of the ram 14 is separated from the end face of the accessory milling head 1 is reached, but the liquid adsorption effect is most obvious. And then, the blind rivet is continuously moved for 2mm, the adsorption effect fails at the moment, the accessory milling head 1 moves leftwards together with the supporting mechanism under the guidance of the linear guide rail 6, the spring 11 is compressed for 2mm (the maximum deformation of the spring is designed to be 5mm), and the ram end face and the accessory milling head end face are also separated for 2mm at the moment. Then the ram withdraws from the base body head stock 7, and the mechanism is restored to the head changing position (original position) under the action of the spring force. So far, the action of warehousing the accessory milling head 1 is completed.
