[0002] Clamping devices are widely used in the manufacturing and processing industry. Sometimes, it is necessary to fix the target object in sequence from multiple directions during the manufacturing and processing process.

Detailed Implementation
[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0019] like Figure 1-3 As shown, a segmented clamp includes a base plate 10, a placement platform 11, a cylinder 12, an upper clamping module, and an upper clamping module. The cylinder 12 is mounted on one side of the base plate 10, and the placement platform 11 is fixedly mounted on the other side of the base plate 10. A lateral clamping module is positioned between the cylinder 12 and the placement platform 11, and an upper clamping module is mounted above the lateral clamping module. Both the lateral clamping module and the upper clamping module are connected to the cylinder 12. The lateral clamping module can fix the object to be clamped from the side, and the upper clamping module can clamp the object from the top after the lateral clamping is completed.
[0020] The cylinder 12 is hinged to the edge of the base plate 10, and a mounting seat for installing the lateral clamping module is provided on the base plate 10 between the cylinder 12 and the placement platform 11.
[0021] The lateral clamping module includes a lateral base rod 13, an L-shaped rod 14, a side clamp 15, a side clamp fixing knob 16, a slider 18, and a slide rod 19. The lateral base rod 13 is hinged to the mounting base of the base plate 10. The cylinder 12 and the lateral base rod 13 are on the same horizontal plane. The rotation direction of the cylinder 12 and the lateral base rod 13 around the hinge point is the same, and they are perpendicular to the placement surface of the placement platform 11. The slide rod 19 is fixedly connected to the top of the lateral base rod 13. The slider 18 is slidably mounted on the slide rod 19, and the extended end of the cylinder 12 is hinged to the slider 18. One end of the L-shaped rod 14 is fixedly mounted on the side of the lateral base rod 13 facing away from the cylinder 12. The other end of the L-shaped rod 14 is detachably mounted with the side clamp 15 via the side clamp fixing knob 16.
[0022] When lateral clamping is required, the cylinder 12 is activated, the extended end of the cylinder 12 is extended, and the slider 18 is pushed so that the slide rod 19 drives the lateral bottom rod 13 to rotate around the hinge point toward the placement table 11, thereby causing the L-shaped rod 14 fixed on the lateral bottom rod 1 to drive the side clamp 15 to clamp the object to be clamped on the placement table 11 from the side.
[0023] The upper clamping module includes a horizontal rod 17, a slide head 20, a return spring 21, a push rod 22, an upper clamp 23, and an upper clamp fixing knob 24. One end of the slide head 20 is fixedly connected to the top of the slide rod 19, and the other end of the slide head 20 is hinged to the middle of the horizontal rod 17. One end of the push rod 22 is hinged to the protruding end of the cylinder 12 through the same hinge point, and the other end of the push rod 22 is hinged to one end of the horizontal rod 17. The return spring 21 is located on the upper side of the slide rod 19. One end of the return spring 21 is fixedly connected to the upper end of the slider 18, and the other end of the return spring 21 is fixedly connected to the lower end face of the slide head 20. The upper clamp 23 is detachably provided on the end of the horizontal rod 17 near the placement platform 11 through the upper clamp fixing knob 24.
[0024] After the lateral clamping module completes clamping, the continued extension of the cylinder 12 will cause the upward component of the force received by the slider 18 along the slide rod 19 to be greater than the elastic force of the return spring 21. The slider 18 compresses the return spring 21 and moves upward, thereby causing the push rod 22 to push one end of the horizontal rod 17 upward, causing the horizontal rod 17 to rotate around the hinge point of the slide rod head 20, thereby causing the upper clamp 23 of the horizontal rod 17 near the placement table 11 to fix the object to be clamped on the placement table 11 from the top. It is worth mentioning that when the cylinder 12 extends, since there is no lateral return spring 21 to provide a reverse force, it will first push the lateral bottom rod 13 to perform lateral clamping when it just extends. When lateral movement is impossible, it will overcome the elastic force of the return spring 21 to complete clamping from the top, thereby realizing the front and rear clamping sequence.
[0025] Cylinder 12, side bottom rod 13, L-shaped rod 14, horizontal rod 17, slide rod 19 and push rod 22 are all located on the same horizontal plane; the rotation direction of cylinder 12, side bottom rod 13, slide rod head 20 and push rod 22 around the hinge point is perpendicular to the placement surface of the placement platform 11.
[0026] The structure of the upper chuck 23 and the side chuck 15 is selected according to the clamping requirements.
[0027] In one embodiment, the upper clamp fixing knob 24 and the side clamp fixing knob 26 are threadedly connected to the upper clamp 23 and the side clamp 15, respectively. By unscrewing the knobs from the upper clamp 23 and the side clamp 15, the structure of the upper clamp 23 and the side clamp 15 can be changed to achieve different effects.
[0028] In one embodiment, the side clamp 15 and the side clamp fixing knob 16 are connected to the L-shaped rod 14 with a counterweight system. By using counterweights or a low center of gravity design, the posture of the top component is automatically adjusted by gravity so that the clamping surface of the side clamp 15 is perpendicular to the placement surface of the placement table 11 during the clamping process.
[0029] In one embodiment, the upper chuck 23 and the upper chuck fixing knob 24 are also provided with a counterweight system at the connection with the horizontal bar 17. By using counterweights or a low center of gravity design, the posture of the top component is automatically adjusted by gravity so that the clamping surface of the upper chuck 23 is horizontal relative to the placement surface of the placement table 11 during the clamping process.
[0030] The above embodiments are merely descriptions of preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Various modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the design concept of the present invention should fall within the protection scope of the present invention.
