Description

Technical Field

[0001] This utility model relates to the field of clamping mechanism technology, specifically a multi-angle rotary clamping mechanism. Background Technology

[0002] Existing clamping mechanisms are used in scenarios such as precision parts processing, semiconductor packaging, and multi-angle inspection of optical devices.

[0004] 2. Unsynchronized clamping: Single-point clamping can easily lead to product displacement. Multi-cylinder external support structure is complex and costly.

[0005] Therefore, a multi-angle rotating clamping mechanism needs to be designed. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] A multi-angle rotary clamping mechanism, such as Figures 1-4As shown, the rotary clamping mechanism includes a base 1, a guide shaft 10 fixedly mounted on the base 1, a base 11 mounted on the guide shaft 10, an X-axis rotating base 12 mounted on the base 11, a stand 13 fixedly mounted on the X-axis rotating base 12, and a Y-axis pitch adjustment frame 14 mounted on the stand 13.

[0027] In this embodiment, the X-axis rotating base is equipped with a 360° annular scale (minimum division 1°), and the worm gear is driven by a handwheel to achieve horizontal rotation and self-locking (accuracy ±0.05°).

[0028] Y-axis pitch adjustment bracket: The bracket side wall is equipped with 0-90° angle scale lines. The pitch is adjusted by pushing the arc-shaped guide rail with a screw, and then fixed by a pin after locking (5° increment).

[0029] A cylinder 2 is fixedly mounted on the Y-axis pitch adjustment bracket 14, and a hollow seat 21 is fixedly mounted on the housing of the cylinder 2.

[0030] The output end of cylinder 2 moves within the hollow seat 21, and the output end of cylinder 2 is fixedly connected to an array of push shafts 22.

[0031] A groove 23 is provided on the hollow seat 21, and a support rod 24 is slidably provided in the groove 23. One end of the support rod 24 extends out of the groove 23 and is internally supported and clamped, while the other end is provided with a sliding hole 27, which is slidably connected to the push shaft 22.

[0032] A crossbar 26 is fixedly installed inside the inclined groove 23, and a sliding groove 25 is provided on the support rod 24, which is slidably connected to the crossbar 26.

[0033] The cylinder 2 pushes the push shaft 22 to move to the front end, and then the push shaft 22 slides and connects with the sliding hole 27. Then the push support rod 24 moves into the inclined groove 23, and the outer end of the support rod 24 extends out of the inclined groove 23 to internally support and fix the product. The crossbar 26 limits the sliding groove 25.

[0034] One end of the hollow base 21 is provided with an array of guide rods 3. One end of the guide rod 3 is fixed with a spring 31, and the other end is fixed with a guide block 32. When the product moves toward the guide block 32, it is guided by the guide block 32 to be guided to the coaxial position with the hollow base 21 for easy clamping and fixing. The spring 31 is fixedly connected to the hollow base 21.

[0035] In use, the cylinder 2 controls the push shaft 22 to move forward, which pushes the support rod 24 to slide in the inclined groove 23, so that multiple support rods 24 move outward synchronously and then clamp synchronously. The inclined guide makes the four support rods 24 synchronously support and clamp the workpiece.

[0036] The clamping angle and orientation can be adjusted by using the X-axis rotating base 12 and the Y-axis pitch adjustment bracket 14.
