DETAILED DESCRIPTION

[0017] In order to more clearly illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings. Obviously, the drawings described below are only one embodiment of the present invention. For ordinary technicians in this field, without paying any creative work, other embodiments can be obtained based on these drawings and embodiments, which all fall within the scope of protection of the present invention.

[0018] according to Figure 1-4 As shown, a quick clamping device for a woodworking machine processing platform includes a base 1, a clamping groove 2 for placing a workpiece 19 is provided on the base 1, a V-shaped seat 3 is movably installed at the bottom of the clamping groove 2, and clamping components are provided on both sides of the clamping groove 2. The clamping components include an active push rod 4 and a passive push rod 5, which are movably installed on the side walls of the clamping groove 2 respectively, and a pressure sensor 6 is fixedly installed on the active push rod 4, and the pressure sensor 6 is connected to the electric telescopic rod 7.

[0019] In this embodiment, a first mounting groove 8 is opened on the right side wall of the clamping groove 2, the active push rod 4 is slidably installed in the first mounting groove 8, the electric telescopic rod 7 is fixedly installed on the right side outer wall of the base 1, and the power output end of the electric telescopic rod 7 is fixedly installed with a pressure sensor 6. The active push rod 4 is driven by the electric telescopic rod 7 to press against the workpiece 19, and the thrust of the electric telescopic rod 7 is detected by the pressure sensor 6 to avoid excessive thrust causing the surface of the workpiece 19 to be clamped.

[0020] In this embodiment, a second mounting groove 9 is provided on the left side wall of the clamping groove 2, and the passive ejector rod 5 is slidably installed in the second mounting groove 9. A fixing plate 10 is fixedly installed on the top of the second mounting groove 9, and a pressure block 11 is slidably installed on the top of the fixing plate 10. The pressure block 11 is provided with a wedge-shaped surface 111 at one end close to the V-shaped seat 3. The pressure block 11 and the passive ejector rod 5 are connected to each other through a transmission assembly. The transmission assembly includes a connecting rod 12, a through slot 101 is provided on the fixing plate 10, and the connecting rod 12 rotates It is installed in the through groove 101, and connecting blocks 13 are hingedly installed at both ends of the connecting rod 12. The pressure block 11 and the passive ejector rod 5 are longitudinally provided with a guide groove 14 at one end away from the V-shaped seat 3. The connecting block 13 is slidably installed in the guide groove 14. When the workpiece 19 squeezes the passive ejector rod 5, the pressure block 11 is pushed toward the workpiece 19 with the cooperation of the connecting block 13 and the connecting rod 12. The wedge surface 111 of the pressure block 11 abuts against the side wall of the workpiece 19, thereby limiting the longitudinal movement of the workpiece 19 through the pressure block 11.

[0021] In this embodiment, a slide groove 15 is provided at the bottom of the clamping groove 2, and a slide seat 16 is installed in the slide groove 15. The V-shaped seat 3 is fixedly installed on the slide seat 16. A spring 17 is welded on the side wall of the V-shaped seat 3 close to the passive push rod 5, and the other end of the spring 17 is welded to the side wall of the clamping groove 2. A limiting block 18 is welded on one end of the slide groove 15 close to the active push rod 4. The workpiece 19 is placed on the V-shaped seat 3. When the workpiece 19 is clamped and positioned, the V-shaped seat 3 will approach the passive push block with the workpiece 19. At this time, the spring 17 is in a compressed state. When unloading, the electric telescopic rod 7 drives the active push rod 4 to retract. Under the action of the spring 17, the V-shaped seat drives the workpiece 19 to move toward the middle of the clamping groove 2, so that the operator can take the workpiece 19.

[0022] When the present invention is in use, the workpiece 19 is first placed on the V-shaped seat 3, and then the electric telescopic rod 7 is started. The electric telescopic rod 7 drives the active push rod 4 to push the workpiece 19 toward the passive push rod 5, and the V-shaped seat 3 will move synchronously with the workpiece. Under the extrusion of the workpiece 19, the passive push rod 5 moves inward, and the pressure block 11 is pushed toward the workpiece 19 under the cooperation of the connecting block 13 and the connecting rod 12, so that the wedge surface 111 abuts against the side wall of the workpiece 19, thereby limiting the longitudinal movement of the workpiece 19 through the pressure block 11, thereby realizing rapid positioning of the workpiece 19 under the cooperation of the V-shaped seat 3 and the clamping assembly, which is conducive to improving processing efficiency. During the positioning process, the V-shaped seat 3 moves synchronously with the workpiece 19, which can effectively prevent the workpiece 19 from scratching the bottom surface when moving in the clamping groove 2. At the same time, the pressure sensor 6 detects the thrust of the electric telescopic rod 7 to prevent the surface of the workpiece 19 from being clamped due to excessive thrust.
