An electromagnet is arranged on the upper connecting seat, and an adsorption piece is arranged on the lower connecting seat. When the upper connecting seat is connected with the lower connecting seat, the electromagnet is magnetically connected with the adsorption piece.

[0008] Through the above technical scheme, the upper connecting seat and the lower connecting seat are connected by an electromagnet and an adsorption piece.

DETAILED DESCRIPTION

[0037] The following is combined with Figure 2-5 This application is described in further detail.

[0038] Reference Figure 2 and Figure 3 The present embodiment discloses a quick clamping mechanism for tool installation, including an upper connecting seat 1 and a lower connecting seat 2. An annular electromagnet installation groove 103 is provided at the lower end of the upper connecting seat 1. An electromagnet 3 is provided in the annular electromagnet installation groove 103. The electromagnet 3 can be fixed in the electromagnet installation groove 103 by means of screws, buckles, etc. An annular adsorption member installation groove 202 is provided at the upper end of the lower connecting seat 2. An adsorption member 4 can be fixed in the adsorption member installation groove 202 by means of screws, buckles, etc. The adsorption member 4 is a material that can be adsorbed by the electromagnet 3 when it is energized. In the present embodiment, iron is used. When the lower connecting seat 2 is installed on the upper connecting seat 1, the annular electromagnet mounting groove 103 corresponds to the annular adsorption member mounting groove 202, so that the electromagnet 3 and the adsorption member 4 are in contact. When the electromagnet 3 is energized, the electromagnet 3 adsorbs the adsorption member 4, so that the upper connecting seat 1 and the lower connecting seat 2 are connected together. When the electromagnet 3 is powered off, the electromagnet 3 is disconnected from the adsorption member 4, thereby disconnecting the upper connecting seat 1 and the lower connecting seat 2.

[0039] Reference Figure 3 and Figure 4In order to prevent the upper connecting seat 1 and the lower connecting seat 2 from being disconnected suddenly due to the sudden power failure of the electromagnet 3 during operation, thus causing an accident, a protective mechanism is also provided between the upper connecting seat 1 and the lower connecting seat 2, and the protective mechanism includes a connecting portion 501, and there are 4 connecting portions 501, each of which is a quarter-ring structure, and the 4 connecting portions 501 are combined into a circular clamping ring. A cylinder 601 is connected to the side of each connecting portion 501 through a connecting sleeve 7, and the piston rod of the cylinder 601 is connected to one end of the connecting sleeve 7, and the other end of the connecting sleeve 7 is connected to the connecting portion 501 through a screw. The cylinder 601 is fixed to the upper connecting seat 1 through a mounting seat 602, and a positioning block 603 is provided on the mounting seat 602, and a positioning groove 101 is provided on the upper connecting seat 1, and the mounting seat 602 is installed in the positioning groove 101 through the positioning block 603, and the mounting seat 602 is fixed to the upper connecting seat 1 through a screw.

[0040] The cylinder 601 is in motion, driving each connection part 501 to move away from the upper connection seat 1 and the lower connection seat 2, so that each connection part 501 has no contact with the upper connection seat 1 and the lower connection seat 2. At this time, the upper connection seat 1 and the lower connection seat 2 can be separated only by losing power to the electromagnet 3. The cylinder 601 is in motion, driving each connection part 501 to move toward the upper connection seat 1 and the lower connection seat 2. When the connection part 501 moves toward the upper connection seat 1 and the lower connection seat 2, the four connection parts 501 will be combined into a circular ring structure. At this time, each connection part 501 will connect the upper connection seat 1 and the lower connection seat 2 together. At this time, if the electromagnet 3 loses power, the upper connection seat 1 and the lower connection seat 2 will still be connected together under the action of the connection part 501, and the separation and disengagement phenomenon will not occur.

[0041] The connecting portion 501 is connected to the upper connecting seat 1 and the lower connecting seat 2 by the following structure. Figure 3 and Figure 5 A connecting protrusion 502 is arranged at the lower end of each connecting portion 501 near the side of the lower connecting seat 2. Each connecting protrusion 502 is a quarter-circular ring structure. When the four connecting portions 501 are put together, the four connecting protrusions 502 form a circular convex ring. A recessed portion 201 is arranged at the bottom end of the lower connecting seat 2. The recessed portion 201 is a ring-shaped structure. When the four connecting portions 501 are put together, the circular convex ring formed by the four connecting protrusions 502 is inserted into the recessed portion 201, thus completing the connection between the connecting portion 501 and the lower connecting seat 2. In this embodiment, the recessed portion 201 is a notch with an L-shaped cross section. Of course, the recessed portion 201 can also be an annular groove.

[0042] Reference Figure 4 and Figure 5 The upper end of the connecting portion 501 is connected to the upper connecting seat 1 through a guiding mechanism. In this embodiment, the guiding mechanism includes a guiding block 503 arranged at the upper end of the connecting portion 501, and a guiding groove 101 is arranged on the upper connecting seat 1, and the guiding block 503 can slide in the guiding groove 101.

[0043] The workflow of this embodiment is:

[0044] When the tool needs to be replaced, first, the cylinder 601 is used to drive each connection part 501 to move away from the upper connection seat 1, so that each connection part 501 is disengaged from the lower connection seat 2. At this time, the electromagnet 3 is powered off, and the lower connection seat 2 can be separated from the upper connection seat 1. The lower connection seat 2 is removed, and then a new tool is replaced. The tool to be replaced is installed together with the lower connection seat 2 on the upper connection seat 1, and the electromagnet 3 is turned on. The electromagnet 3 adsorbs the adsorption part 4 on the lower connection seat 2, thereby fixing the upper connection seat 1 and the lower connection seat 2 together. Then start the cylinder 601, which drives the connecting part 501 to move towards the direction close to the upper connecting seat 1, and the connecting protrusion 502 at the lower end of the connecting part 501 is inserted into the recessed part 201 on the lower connecting seat 2. When the four connecting parts 501 are assembled into a circular ring structure, it means that the connecting part 501 moves into place. At this time, the cylinder 601 stops. At this time, the protective mechanism formed by the connecting part 501 and the like connects and fixes the upper connecting seat 1 and the lower connecting seat 2, which can prevent the upper connecting seat 1 and the lower connecting seat 2 from being suddenly disconnected due to a sudden power failure of the electromagnet 3.

After reading this specification, those skilled in the art may make modifications to the present embodiment without any creative contribution as needed, but such modifications are protected by the patent law as long as they are within the scope of the claims of the present application.
