[0025] By providing the four-corner clamping assembly 2, the workpiece can be clamped and fixed at the four corners to increase stability and prevent the workpiece from shifting during processing. Starting the electric push rod 206 can drive the four clamping jaws 203 to move outward or inward at the same time.

[0026] See also Figures 1 to 4 The slide groove 201 is provided at the bottom of the housing 1, the movable block 202 is slidably connected to the inside of the slide groove 201, the clamping claw 203 is fixedly connected to the bottom of the movable block 202, the slider 204 is fixedly connected to both sides of the movable block 202, the limiting groove 205 is provided on one side of the movable block 202, the electric push rod 206 is fixedly connected to the inner top wall of the housing 1, the connecting plate 207 is fixedly connected to the output shaft of the electric push rod 206, the limiting block 208 is fixedly connected to the surface of the connecting plate 207, and is located inside the limiting groove 205, the limiting groove 205 is in the shape of a trapezoid with a wide inside and a narrow outside, the limiting block 208 is consistent with the model of the limiting groove 205, and the slider 204 is slidably connected to the inner wall of the slide groove 201;

[0027] When fixing the workpiece, start the electric push rod 206 to drive the connecting plate 207 to move upward, so that the limiting blocks 208 on all sides slide in the limiting grooves 205 respectively, which can drive the two relative movable blocks 202 to move in different directions, so that the two relative movable blocks 202 are close to each other, and the four clamping claws 203 can be driven to move toward the workpiece at the same time to clamp and fix the workpiece.

[0028] See also Figure 2 and Figure 5 , a reminder component 5 is arranged inside the clamping jaw 203, and the reminder component 5 includes a light switch 501, a slide bar 502, a collision block 503, a spring 504 and a protection pad 505. The light switch 501 is fixedly installed on the inner wall of one side of the clamping jaw 203, and the slide bar 502 is slidably connected to one side of the clamping jaw 203, and one end of the slide bar 502 is fixedly connected to the collision block 503, and the spring 504 is sleeved on the surface of the slide bar 502, and one end of the spring 504 is fixedly connected to the collision block 503, and the other end of the spring 504 is fixedly connected to the inner wall of the clamping jaw 203, and the other end of the slide bar 502 is fixedly connected to the protection pad 505. The two side surfaces of the housing 1 are fixedly connected with mounting plates 3, and both ends of the one side surface of the mounting plate 3 are installed with LED lamps 4, and the switches of the four LED lamps 4 are four light switches 501 respectively;

[0029] By providing a reminder component 5, a reminder of being in position can be given after the jaws 203 clamp the workpiece. After the protective pad 505 contacts the workpiece during the clamping process, as the jaws 203 continue to move toward the workpiece, the impact block 503 can be driven to move and hit the light switch 501, and then the LED light 4 is turned on to give a reminder of being in position. The four jaws 203 correspond to four LED lights 4 respectively, so that it can be intuitively understood whether the jaws 203 are clamped on the surface of the workpiece.

[0030] In the utility model, the working principle of the device is as follows:

[0031] During operation, the housing 1 is moved to the top of the workpiece so that the four clamping jaws 203 are located at the four corners of the workpiece respectively, and then the electric push rod 206 is started to drive the connecting plate 207 to move upward, so that the limiting blocks 208 on all sides slide in the limiting grooves 205 respectively, which can drive the two relative movable blocks 202 to move in different directions, so that the two relative movable blocks 202 are close to each other, and the four clamping jaws 203 can be driven to move toward the workpiece at the same time, and finally the protection pad 505 is fitted with the surface of the workpiece for clamping and fixing, and the workpiece can be clamped and fixed at the four corners, thereby increasing stability and preventing the workpiece from shifting during processing. By starting the electric push rod 206 to drive the connecting plate 207 to move downward, the four clamping jaws 203 can be driven to reset and release the fixation of the workpiece;

[0032] When the jaws 203 clamp the workpiece, the protection pad 505 first contacts the surface of the workpiece. As the jaws 203 continue to move toward the workpiece, the protection pad 505 is forced to move toward the jaws 203, and the slide bar 502 and the impact block 503 are driven to move, so that the protection pad 505 is finally fitted with the surface of the jaws 203. The impact block 503 then hits the light switch 501 to turn on the LED light 4, so as to provide a reminder of the position. The four jaws 203 correspond to four LED lights 4 respectively. By observing whether the LED lights 4 are on, it is possible to intuitively understand whether the jaws 203 are clamped on the surface of the workpiece. When the jaws 203 are reset, the restriction of the workpiece on the protection pad 505 is released, and the impact block 503 can be driven to reset by the spring 504, so that the distance between the impact block 503 and the light switch 501 is increased, thereby turning off the LED light 4.

[0033] The light switch 501 in the present invention is a self-resetting push button switch, which is a relatively mature technology at present, and its working principle is a well-known technology, so it will not be explained in detail.
