It can be used as a tool to assist in controlling positions and movements. Jigs can be divided into three categories: process assembly jigs, project testing jigs, and circuit board testing jigs. Jigs have a relatively wide range of application fields and a long service time. They have been widely used before the industrial era and are used in the fields of mechanical jigs, woodworking jigs, welding jigs, and jewelry jigs. The shapes and sizes of jigs used for different products are different.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0027] The following combines the attached Figures 1-5Further description of the present utility model.

[0028] To solve the problems existing in the background art, the present application proposes the following technical solution: a clamping mechanism facilitating rapid fixture switching.

[0029] In the specific technical solution, it includes a gantry 1, a lifting and supporting component 5, and a clamping component 6;

[0030] As Figures 1-5 shown, a pneumatic floating ball 2, a travel switch 3, and a sensor 4 are respectively installed above and on two side walls of the gantry 1. The pneumatic floating ball 2 is used to drive the fixture to rise, and the travel switch 3 and the sensor 4 are used to sense the position of the fixture; the lifting and supporting component 5 is installed at the bottom of the gantry 1, and the lifting and supporting component 5 is used to support the bottom of the fixture. The lifting and supporting component 5 includes a bearing block 501 fixedly installed at the bottom of the gantry 1 and a cross plate 502 located above the gantry 1. The bearing block 501 can fix the first cylinder 503 and can also limit the guide post 505. The cross plate 502 can support the positioning pin 504. A first cylinder 503 with a telescopic end fixedly connected to the cross plate 502 is fixedly penetrated in the bearing block 501. The first cylinder 503 can drive the cross plate 502 to rise and fall. A positioning pin 504 and a guide post 505 penetrating through the bearing block 501 are symmetrically installed on the top and bottom surfaces of the cross plate 502 respectively. The positioning pin 504 can fix and support the bottom of the fixture, and the guide post 505 can limit the cross plate 502; the clamping component 6 is installed on the side wall of the gantry 1, and the clamping component 6 is used to clamp both sides of the fixture. The clamping component 6 includes two clamping structures symmetrically installed at both ends of the gantry 1. The clamping structure includes a fixing plate 601 fixedly installed on the bottom surface of the gantry 1 and a second cylinder 602. The fixing plate 601 can fix the second cylinder 602, and the second cylinder 602 can drive the support plate 603 to move. The second cylinder 602 is fixedly connected to the fixing plate 601 and a support plate 603 is fixedly installed at its telescopic end. The support plate 603 can support the pressing block 604. A pressing block 604 located above the gantry 1 is fixedly installed at the top of the support plate 603. The pressing block 604 can fix the side wall of the fixture.

[0031] The fixture is located in the middle of the top surfaces of the mounting table 1 and the pneumatic floating ball 2. By supplying air to the pneumatic floating ball 2, the pneumatic floating ball 2 rises and drives the fixture to rise. After the fixture rises to the set position above the mounting table 1, it can be sensed by the travel switch 3, and the travel switch 3 controls the activation of the first cylinder 503. The first cylinder 503 drives the cross plate 502 to rise, and the cross plate 502 drives the positioning pin 504 and the guide post 505 to rise. The guide post 505 can limit the cross plate 502 to keep the cross plate 502 stable. After the positioning pin 504 rises, it inserts into the bottom of the fixture to prevent the fixture from sliding down. At the same time, the pneumatic floating ball 2 descends and loses the support for the bottom of the fixture, and the pneumatic floating ball 2 can reset. At the same time, the sensor 4 senses the fixture, and the sensor 4 controls the activation of the second cylinder 602. The second cylinder 602 drives the support plate 603 to move, and the support plate 603 drives the pressing block 604 to move towards the fixture. The two support plates 603 clamp on both sides of the fixture, and the side wall of the fixture is fixed. After the fixture is quickly fixed, it is convenient to switch the fixtures on the fixture.

[0032] As Figures 1-2 and Figure 4 shown, a supporting block 7 is fixedly installed on the side wall of the fixed plate 601 and is located below the support plate 603. The supporting block 7 is installed below the support plate 603 and can support the bottom of the support plate 603, which can increase the stability of the support plate 603. After the support plate 603 is stable, it can increase the stability of the pressing block 604.

[0033] As Figures 1-2 and Figure 4 shown, the fixed end of the second cylinder 602 is fixedly installed with a bottom plate 8 located below the first cylinder 503. The bottom plate 8 connects two symmetrical second cylinders 602, and it is convenient to install an air control valve 9 below the bottom plate 8.

[0034] As Figures 1-2 and Figure 4 shown, an air control valve 9 is fixedly installed below the bottom plate 8. When the air control valve 9 is opened, it can supply gas to the pneumatic floating ball 2 through a pipeline, which is convenient for the pneumatic floating ball 2 to rise after being ventilated.

[0035] As Figures 1-4 shown, a fixed side plate 10 is fixedly installed on the side wall of the mounting table 1, and the fixed side plate 10 can fix the mounting table 1.

[0036] As Figures 1-4 shown, a fixing frame 11 is installed on the side wall of the fixed side plate 10, and the fixing frame 11 can support the fixed side plate 10.

[0037] As Figures 2-3As shown, a third cylinder 12 with a telescopic end fixedly connected to the fixed side plate 10 is fixedly installed on the fixing frame 11. The telescopic end of the third cylinder 12 can fix the fixed side plate 10, and when the third cylinder 12 is activated, it can drive the fixed side plate 10 to move. The fixed side plate 10 drives the frame 1 to move, and the frame 1 drives the pneumatic floating ball 2, the travel switch 3, the sensor 4, the lifting support assembly 5, and the clamping assembly 6 to move, facilitating the adjustment of the distance between the two clamping structures and facilitating the adaptation to different jigs.
