[0030] In the machining process, clamping and fixing cylindrical workpieces (such as shaft parts, pipe parts, etc.) is a critical step. Traditional clamping devices usually use three-jaw chucks or V-blocks for fixing, which can easily lead to workpiece deformation or insecure clamping, affecting machining accuracy. In addition, they also have certain shortcomings in terms of ease of operation. Therefore, developing a cylindrical workpiece clamping and fixing device that is highly adaptable, has uniform clamping force, and is flexible in operation is of great practical significance.

[0031] The design concept of this application is to use a lifting linkage rotation clamping mechanism, which is highly adaptable, provides uniform clamping force, and is flexible in operation.

[0032] like Figure 1-2 As shown, this application provides a cylindrical component clamping and fixing device, including a base 1, a frame 2 connected to the base 1, and a slide 3 located between the base 1 and the frame 2; a pushing mechanism 4 is provided on the base 1, the telescopic end of the pushing mechanism 4 is connected to the bottom of the slide 3, connecting rods 6 are rotatably connected to both sides of the slide 3, the upper middle part of each connecting rod 6 is rotatably connected to the frame 2, the top of each connecting rod 6 is rotatably connected to a base 8, each base 8 is connected to a clamping plate 9, and the space between the two clamping plates 9 is a space for clamping the cylindrical component 10.

[0033] The base 1 is provided with a support column 11, and the top of the support column 11 is provided with a groove. When operating a long cylindrical part 10, the rest of the part except for the clamping part can be placed on the groove, which is more conducive to clamping stability.

[0034] The jacking mechanism 4 uses a hydraulic cylinder, electric cylinder, or pneumatic cylinder; directly using existing equipment is more conducive to the rapid commercialization of the solution.

[0035] The base 1 has guide plates 5 at both ends, and guide grooves are provided on the inner side of the guide plates 5. The guide grooves are slidably connected to the slide block 3. The guide plates 5 and the guide grooves are used to limit the sliding path of the slide block 3.

[0036] The slide block 3 adopts an Ω-shaped structure, and connecting rods 6 are rotatably connected to both sides of the Ω-shaped structure. The two ends of the Ω-shaped structure are slidably connected to the guide groove. In use, the slide block 3 can slide up and down along the guide groove. Pins 31 are provided on both sides of the slide block, and the pins are rotatably connected to the elongated holes.

[0037] The Ω-shaped structure has pins 31 on both sides, and the pins 31 are rotatably connected to the connecting rod 6.

[0038] The bottom of the connecting rod 6 is provided with an elongated hole 7, which is rotatably connected to the slide block 3. The elongated hole 7 facilitates the rotation of the connecting rod 6. The elongated hole 7 is rotatably connected to the pin 31, and the elongated hole 7 can slide and rotate back and forth on the pin 31.

[0039] After installation, the two connecting rods 6 are slightly tapered, with the upper part smaller than the lower part. That is, the connection position of the elongated hole 7 and the pin 31 is on the outside of the connection position between the upper part of the connecting rod 6 and the frame 2 (the connection positions of the elongated holes 7 and the pin 31 on both sides are on the lower left and lower right of the connection position between the upper part of the connecting rod 6 and the frame 2, respectively). This design makes it easier for the two connecting rods 6 to rotate in opposite directions, thereby realizing the action of clamping and releasing.

[0040] Specifically, when clamping, the pushing mechanism 4 starts to extend upward, the slide 3 rises, the left connecting rod 6 rotates clockwise (rotating around the connection position between the upper part of the connecting rod 6 and the frame 2), and the right connecting rod 6 rotates counterclockwise (rotating around the connection position between the upper part of the connecting rod 6 and the frame 2). When releasing, the pushing mechanism 4 starts to retract downward, the slide 3 descends, the left connecting rod 6 rotates counterclockwise (rotating around the connection position between the upper part of the connecting rod 6 and the frame 2), and the right connecting rod 6 rotates clockwise (rotating around the connection position between the upper part of the connecting rod 6 and the frame 2).

[0041] The base 8 adopts a T-shaped structure. The small end of the T-shaped structure is rotatably connected to the top of the connecting rod 6, and the large end of the T-shaped structure is welded to the clamping plate 9. In use, as the connecting rod 6 rotates, the large ends of the T-shaped structures on both sides move closer to each other, that is, the clamping plates 9 on both sides move closer to each other to clamp the workpiece, and vice versa to loosen the workpiece.

[0042] The clamping plate 9 adopts an arc-shaped plate structure; the arc-shaped plate structure is more conducive to fitting the cylindrical parts.

[0043] When this application is used, the push mechanism 4 is activated, the telescopic end moves up and down, driving the slide 3 to move up and down, thereby causing the connecting rods 6 on both sides to swing left and right, thus achieving the clamping or loosening of the workpiece.

[0044] Although the present invention has been described in detail with reference to the accompanying drawings and preferred embodiments, the present invention is not limited thereto. Without departing from the spirit and essence of the present invention, those skilled in the art can make various equivalent modifications or substitutions to the embodiments of the present invention, and such modifications or substitutions should all be within the scope of the present invention. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should also be included within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the protection scope of the claims.
