Fig. 3 is cutting ferrule connection set of the present utility model left TV structure schematic diagram embodiment illustrated in fig. 2.
Embodiment
Below in conjunction with accompanying drawing, cutting ferrule connection set one preferred embodiment in the utility model is further elaborated to explanation.
In prior art as shown in Figure 1, this old-fashioned cutting ferrule adopts thread bush form to connect described thread type cutting ferrule 2, and thread type cutting ferrule 2 is connected with pull bar 1 on the one hand, is connected on the other hand with oil cylinder 3.What original ZGM medium speed grinding lira bar and oil cylinder adopted is old-fashioned thread type cutting ferrule 2.The pull bar and the mailbox that in the time of the long-time use of process and dismounting maintenance, easily caused afterwards damage, reason to be that old-fashioned employing thread bush form connects easily cause easily concentrated, easy-rupturing of stress, and safety coefficient is little, is not easy to install and overhaul, and bearing strength is little.
Embodiment 1:
Be the structural representation of cutting ferrule connection set one preferred embodiment of the present utility model as Figure 2-3, comprise two cutting ferrule 7, the first pull bar being fixedly connected with by cutting ferrule 7 and the second pull bars that pairing body forms that are bolted to connection, cutting ferrule 7 links together pull bar and load cylinder to play the effect being fixedly connected with.Cutting ferrule 7 adopts 45# steel to make.The outer surface of the internal surface of each pairing body connection corresponding to each pull bar is complementary shape, and described complementary shape is axle center hole 6, and this axle center hole is cylindrical hole or is the cylindrical hole with shoulder hole shape.The junction point that described two pairing bodies connect is provided with the radial direction through hole 5 perpendicular to described axle center hole.The diameter of described radial direction through hole 5 is less than the diameter of cutting ferrule axle center hole 6.In described radial direction through hole 5, be inserted with straight pin, with straight pin isolation pull bar and oil cylinder, in case both relatively rotate.Described straight pin one side and the first pull bar movable contact, on the other hand with the second pull bar movable contact.By improvements over the prior art, after change the cutting ferrule connection set in the present embodiment into, adopt removable two pairing bodies, solve the phenomenon of above appearance, meet equipment user demand, the use that has also greatly promoted grinding machine is simultaneously economical.
