[0001] The utility model relates to the technical field of mechanical design and manufacturing, in particular to a positioning and clamping mechanism for mechanical design and manufacturing. Background Art

[0002] Mechanical manufacturing refers to the process of using various mechanical processing technologies and equipment to process raw materials into mechanical parts or finished products with specific functions and uses. Mechanical manufacturing is an important part of modern industry, and its development directly affects the production efficiency and product quality of all walks of life. With the continuous advancement of technology, mechanical manufacturing will develop in a more efficient, intelligent and green direction.

[0003] During the machining process, a clamping mechanism is often required to clamp the workpiece. The clamping end size of the existing clamping mechanism is generally fixed. When facing larger or smaller workpieces, it cannot be adapted and the clamping may be unstable. For this reason, we propose a positioning clamping mechanism for mechanical design and manufacturing.

[0020] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0021] In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0022] Please see the attached Figure 1 -Attached Figure 4 The utility model is a positioning and clamping mechanism for mechanical design and manufacturing, including a fixed frame 1, a power slot 2 is opened in the fixed frame 1, an electric push rod 3 for providing power is installed in the power slot 2, one end of the electric push rod 3 is fixed to the inner wall of the power slot 2, the output end of the electric push rod 3 slides through the fixed frame 1 and continues to extend, and the extended end of the electric push rod 3 is fixedly installed with a rack 4 that can follow the electric push rod 3 to make a reciprocating motion. A plurality of rotating slots 5 are also opened in the fixed frame 1, and a clamping device 6 for clamping a workpiece is installed in the rotating slot 5. The clamping device 6 is symmetrically arranged with the fixed frame 1 as the center, and the clamping device 6 includes a first rotating rod 601, a second rotating rod 602, a connecting rod 603, an arc gear 604 and a clamping block 605.

[0023] In the first embodiment, one end of the first rotating rod 601 is rotatably connected to the rotating groove 5, and the other end is rotatably connected to the end of the second rotating rod 602. One end of the connecting rod 603 is rotatably connected to another rotating groove 5, and the other end is rotatably connected to the second rotating rod 602. The arc gear 604 is fixedly connected to one end of the connecting rod 603 located in the rotating groove 5. The arc gear 604 is meshed with the rack 4. The first rotating rod 601 is arranged in an F-shape with the second rotating rod 602 and the connecting rod 603. The clamping block 605 is installed at the end of the second rotating rod 602 away from the first rotating rod 601.

[0024] Specifically, an electric push rod 3 is arranged in the power slot 2, and a rack 4 is fixed to the output end of the electric push rod 3, so that the electric push rod 3 will drive the rack 4 to move back and forth when working. At the same time, when the rack 4 moves back and forth, it will drive the two sets of clamping blocks 605 to approach each other through the arc gears 604 on both sides, thereby achieving the clamping effect.

[0025] In the second embodiment, a plug plate 7 is fixedly installed on a side of the clamping block 605 close to the second rotating rod 602. The plug plate 7 is slidably inserted into the second rotating rod 602. A limiting column 8 is also installed in the second rotating rod 602. The limiting column 8 passes through the second rotating rod 602 and the plug plate 7 respectively. The plug plate 7 can be fixed in the second rotating rod 602 by relying on the limiting column 8. A clamping groove 9 is formed on the side of the clamping block 605 away from the second rotating rod 602. An anti-slip pad 10 is fixedly installed in the clamping groove 9;

[0026] Specifically, when the size of the clamping block 605 needs to be changed, the limiting column 8 can be pulled out from the second rotating rod 602. At this time, the plug plate 7 can move freely, and then the clamping block 605 of appropriate size can be placed in the second rotating rod 602 and fixed by the limiting column 8.

[0027] Working principle:

[0028] First, start the electric push rod 3. When the electric push rod 3 is pushed outward, it will drive the rack 4 to move outward. Since the rack 4 is meshed with the arc gear 604, the rack 4 will drive the arc gear 604 to move together. Since the arc gear 604 is fixed to the connecting rod 603, one end of the connecting rod 603 is rotatably installed in the rotating groove 5, and the other end is rotatably connected to the second rotating rod 602. The end of the second rotating rod 602 away from the clamping block 605 is rotatably connected to the first rotating rod 601, so that when the arc gear 604 moves, it will pass through the connecting rod 603. Drive the two groups of second rotating rods 602 away from each other. When it is necessary to clamp the workpiece, just drive the electric push rod 3 in the opposite direction. When it is necessary to change the size of the clamping block 605, the limiting column 8 can be pulled out from the second rotating rod 602. At this time, the insert plate 7 can be pulled out from the second rotating rod 602. Finally, put the clamping block 605 of appropriate size into the second rotating rod 602 and fix it through the limiting column 8. The anti-slip pads 10 set on the opposite surfaces of the two groups of clamping blocks 605 can effectively avoid slipping during clamping. At this point, the entire work process ends.
