The air detection type wedge presser and the connecting seat 2 are fixed on the clamp. The driving cylinder 1 is fixed on the connecting seat 2 through a screw, and the pneumatic connector 3 is fixed on the connecting seat 2 through threads. The pneumatic connector 4 is fixed on the connecting seat 2 through threads. The lateral oil cylinder 5 is fixed on the connecting seat 2 through a screw. The right side of the joint 6 is connected to a piston rod of the lateral oil cylinder 5 through threads, and a left boss of the joint 6 is inserted into a right groove of the lateral shaft 8. Big spring 7 is installed in the hole of side direction axle 8, and the left end face of big spring 7 and the terminal surface contact in the hole of side direction axle 8, and the right-hand member face contacts with the boss left side of joint 6. The lateral shaft 8 is mounted in a horizontal hole of the connecting socket 2 and is axially movable. The ram 9 is mounted in a hole in the lower end of the tightening shaft 14 so as to be axially movable. The pin shaft 10 passes through a hole on the pressure head 9 and is arranged in a transverse pin hole at the lower part of the jacking shaft 14. Two ends of the pin shaft 10 are clamped by clamp springs, so that the pin shaft 10 is prevented from falling off along the axial direction. The pneumatic connector 12 is fixed on the connecting base 2 through threads. The tightening shaft 14 is mounted in a vertical hole of the connecting seat 2 and can move along the axial direction of the vertical hole. The side cover plate 13 is fixed on the side surface of the connecting base 2 to prevent sundries from entering the horizontal hole of the connecting base 2. The upper part of the tightening shaft 14 is connected with the piston rod of the driving cylinder 1 through a thread. The piston rod of the driving cylinder 1 can drive the jacking shaft 14 to move along the vertical hole on the connecting seat 2. The pneumatic connector 15 is fixed on the connecting seat 2 through threads.
When the air detection type wedge presser is ejected, the driving cylinder 1 drives the jacking shaft 14 to move downwards through the piston rod, and the jacking shaft 14 drives the pressing head 9 to move downwards through the small spring 11. If the knock-up shaft 14 is not pressed against the workpiece, the compressed air blown from the pneumatic connector 12 escapes from the hole 14.6 in the knock-up shaft 14 through the holes 14.4 and 14.3 in the knock-up shaft 14 and the gap between the ram 9 and the knock-up shaft 14. And the machine tool gives an alarm when the workpiece is not pressed. In a normal state, when the pressing shaft 14 presses the workpiece, the upper end surface of the pressing head 9 contacts the bottom surface of the lower hole of the pressing shaft 14. The compressed air blown from the pneumatic connector 12 is sealed and the air detection mechanism sends a signal indicating that the ram 9 has pressed against the workpiece. At this time, the compressed air blown out from the pneumatic connector 15 escapes through the hole 2.1 on the connecting seat 2, and the corresponding air detection mechanism sends out a signal to indicate that the jacking shaft 14 is not at the upper end. Then, the lateral oil cylinder 5 acts through the control of a machine tool or a sequence valve, the piston rod drives the joint 6 to move leftwards, the joint 6 extrudes the large spring 7 rightwards, the large spring 7 drives the lateral shaft 8 to move leftwards and insert into the through cavity of the jacking shaft 14 until the left side surface of the lateral shaft 8 is in contact with the through cavity surface of the jacking shaft 14. Then, the left boss surface of the joint 6 continuously compresses the large spring 7 until the left boss surface of the joint 6 contacts the left side surface of the stepped groove 8.3 of the lateral shaft 8, so that the lateral oil cylinder 5 stably applies force to the lateral shaft 8, and the jacking shaft 14 outputs heavy pressure to press on a workpiece. Because the slope of the inclined plane on the left side of the lateral shaft 8 is smaller than the friction angle between the lateral shaft 8 and the jacking shaft 14, the mechanism is self-locked, and the jacking shaft 14 reliably compresses the workpiece. After the left side surface of the lateral shaft 8 presses the jacking shaft 14, the inclined surface of the inclined step through cavity 14.1 of the jacking shaft 14 seals the compressed air blown to the left side 8.4 of the lateral shaft 8 from the pneumatic connector 3, and the air detection mechanism sends a signal to indicate that the lateral shaft 8 moves in place. At this time, the compressed air blown out by the pneumatic connector 4 escapes through the 2.4 holes on the connecting seat 2, and the corresponding air detection mechanism sends out a signal to indicate that the lateral shaft 8 is not positioned on the right side. The action is completed.
When the air detection type wedge presser retracts, the piston rod of the lateral oil cylinder 5 retracts to drive the joint 6 to move rightwards, after the joint 6 moves rightwards for a certain distance, the right side face of the boss at the left side of the joint 6 collides with the right side face of the stepped groove 8.3 of the lateral shaft 8, self-locking of the lateral shaft 8 and the jacking shaft 14 is opened through the inertia effect and hydraulic pressure of the joint 6, the left side of the lateral shaft 8 is separated from contact with the jacking shaft 14, and the lateral shaft 8 moves rightwards until the piston rod of the lateral oil cylinder 5 moves to the bottom. At this point the lateral shaft 8 is sealed from the compressed air blown from the pneumatic connector 4 and the air detection mechanism sends a signal indicating that the lateral shaft 8 has moved into position.
Meanwhile, compressed air blown out from the pneumatic connector 3 escapes from the hole 2.3 in the connecting seat 2 through the annular groove 8.5 in the lateral shaft 8, and the corresponding air detection mechanism sends a signal to indicate that the lateral shaft 8 is not on the left side. Then, through the control of a machine tool or a sequence valve, the piston rod of the driving cylinder 1 retracts, and the jacking shaft 14 is driven to move upwards to a proper position. The small spring 12 pushes the ram 9 downwards. The upper end face of the ram 9 is released from contact with the knock shaft 14. The tightening shaft 14 drives the pressing head 9 to move upwards together through the pin shaft 10. At this time, the upper portion of the knock-up shaft 14 seals the compressed air blown from the pneumatic connector 15, and the air detecting mechanism sends a signal indicating that the knock-up shaft 14 has moved into position. Meanwhile, compressed air blown out from the pneumatic connector 12 escapes from the first small hole 2.2 on the connecting seat 2 through the annular groove 14.7 at the lower part of the jacking shaft 14, and the corresponding air detection mechanism sends out a signal to indicate that the jacking shaft 14 is in a retraction state. The action is ended.
The working principle is as follows: this is a gas-check wedge impactor. The jacking shaft 14 is driven to move until contacting the workpiece by extending the piston rod of the driving cylinder 1. The self-locking of the mechanism is realized by extending the piston rod of the lateral oil cylinder 5, and the jacking shaft 14 reliably compresses the workpiece. The air port is opened and closed to realize the action of in-place air detection.
Finally, it should be noted that the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to examples, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, which should be covered by the claims of the present invention.
