DETAILED DESCRIPTION

[0027] The embodiments of the present invention are described in detail below. Figures 1 to 7 The embodiment of the utility model provides a simple multi-station linkage positioning device, including: a base 100, a telescopic structure 200, an elastic structure 300 and a positioning structure 400, the workpiece 600 is located on the upper end surface of the base 100; the telescopic structure 200 is located on the base 100, the telescopic structure 200 includes a cylinder 210 and a guide rod 220, the guide rod 220 can be extended and retracted with the cylinder 210, the guide rod 220 is connected to the cylinder 210, and a retractable pushing part 221 is provided on the guide rod 220; the elastic structure 300 is connected to the guide rod 220; the positioning structure 400 is connected to the base 100, and the guide rod 220 can be extended and retracted with the cylinder 210, At the same time, it drives the pushing part 221 provided on the guide rod 220, and the workpiece 600 is always between the pushing part 221 and the positioning structure 400. When the cylinder 210 drives the guide rod 220 to extend, the pushing part 221 can move to contact the workpiece 600 and push the workpiece 600 to move synchronously. When the other side of the workpiece 600 contacts the positioning structure 400, the workpiece 600 stops moving and the positioning is completed. The cylinder 210 continues to drive the guide rod 220 to extend and retract to compress the spring on the guide rod 220, so that the positioning device can adapt to workpieces 600 of different widths. Of course, the positioning device does not limit the structure and shape of the base 100. Preferably, the base 100 is a cylindrical structure.

[0028] Further, refer to Figure 2 and Figure 4 , a connecting block 110 is provided on the base 100, and the cylinder 210 and the guide rod 220 are connected through the connecting block 110. Of course, the present device does not limit the specific connection method of the guide rod 220 and the connecting block 110. Preferably, a through hole 120 is provided on the base 100, and the guide rod 220 is plugged into the through hole 120, and the guide rod 220 is plugged into the connecting block 110. At the same time, the cylinder 210 and the connecting block 110 are tightened and fixed by screws. When the cylinder 210 is working, it drives the connecting block 110 to extend and retract together, and the connecting block 110 synchronously drives the guide rod 220 to move together, so as to realize the movement of the pin on the guide rod 220, so that one side of the workpiece 600 contacts the pin, and further promotes the movement of the workpiece 600. Further, referring to Figure 5 and Figure 6The guide rod 220 is provided with a mounting groove 222, and the push portion 221 is plugged into the mounting groove 222. Of course, the present device does not limit the structure of the mounting groove 222. Preferably, the mounting groove 222 is a waist-shaped hole 150, and the push portion 221 can reciprocate in the mounting groove 222 under the action of the elastic structure 300. Further, referring to Figure 7 A moving tube 500 is also sleeved on the guide rod 220, and a pin outlet 510 is provided on the moving tube 500. The pushing portion 221 passes through the mounting groove 222 and is inserted into the pin outlet 510. Preferably, the moving tube 500 is made of copper material to make the guide rod 220 smooth during movement. Of course, the positioning device does not limit the specific structure of the pushing portion 221. The pushing portion 221 is used to push the movement of the workpiece 600. Preferably, the pushing portion 221 is a pin.

[0029] Furthermore, referring to 4 and Figure 5 The elastic structure 300 is a spring, which is sleeved on the guide rod 220. When the cylinder 210 drives the guide rod 220 to move together and pushes the pin to one side of the workpiece 600, the cylinder 210 continues to drive the guide rod 220 to extend, and the workpiece 600 is always between the pin and the positioning structure 400. The pin moves forward and contacts one side of the workpiece 600. When the other side of the workpiece 600 contacts the positioning structure 400, the workpiece 600 stops moving, but the cylinder 210 still drives the guide rod 220 to continue to extend. The pin cannot continue to move forward, which will cause the moving tube 500 compresses the spring until the cylinder 210 completely stops extending. Through the compression of the spring, the workpieces 600 with different shapes and inconsistent widths can still be positioned against the edge at one time without the need to disassemble and replace the positioning device. Furthermore, the positioning device does not limit the length of the spring and the stroke of the cylinder 210. The length of the spring and the stroke of the cylinder 210 determine the specific width range of the workpiece 600 that can be positioned by the positioning device. According to actual production needs, springs of different lengths and cylinders 210 of different strokes can be replaced to meet the positioning of workpieces 600 of different widths.

[0030] Further, refer to Figure 5 , the number of the pushing parts 221 and the positioning structure 400 is multiple, and the present device does not limit the specific position and size of the positioning device and the pushing part 221. Preferably, the number of the positioning device and the pushing part 221 is the same, the positioning device is arranged longitudinally or transversely, and the multiple pushing parts 221 are also arranged longitudinally or transversely, and the column formed by the positioning device is parallel to the column formed by the pushing device, and the workpiece 600 is always in the range between the positioning device and the pushing part 221. Further, referring to Figure 2A suction structure 130 is provided on the base 100, and the suction structure 130 is connected to one end of the mounting hole 140. The suction structure 130 is used to suction the positioned workpiece 600 to prevent the workpiece 600 from moving. Of course, the positioning device does not limit the specific type of the suction structure 130. Preferably, the suction structure 130 can be a vacuum device. Furthermore, a waist-shaped hole 150 is provided on the base 100, and the waist-shaped hole 150 is connected to the mounting hole 140. The suction device is also connected to the waist-shaped hole through the mounting hole 140. The workpiece 600 is placed above the waist-shaped hole. When the suction device is turned on, the positioned workpiece 600 can be suctioned onto the base 100 through the waist-shaped hole 150, thereby fixing the positioned workpiece 600 at one time.
