Description

Technical Field

[0001] The utility model relates to the technical field of clamping, in particular to a clamping mechanism for blade processing. Background Art

[0002] The fan blade is an important part of the fan, which can generate wind force or other power by rotating. During the fan processing, it is usually necessary to clamp the blade through a clamping mechanism and then perform processes such as grinding.

[0003] However, the end of the existing clamping mechanism is fixedly arranged, so that the blade cannot be flipped after being clamped. When it is necessary to process the back surface of the blade, the blade needs to be taken out, flipped, and then clamped again, which makes the operation steps more cumbersome and the work efficiency lower. Therefore, we propose a clamping mechanism for blade processing to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantages of the existing technology involved in the background art, and to propose a clamping mechanism for blade processing.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A clamping mechanism for blade processing, including a support base. One side of the top of the support base is provided with a fixed seat, and the other side of the top of the support base is provided with a moving seat. A rotating shaft rod is inserted into the top of the moving seat, and a placing seat is arranged at the end of the rotating shaft rod. The placing seat is arranged in a U-shape, and there are two groups of placing seats. The other group of placing seats is movably connected to the fixed seat through a rotating shaft. The placing seat can rotate on the fixed seat or the moving seat, and a threaded adjusting rod is inserted into the top of the placing seat;

[0007] The two ends of the blade can be clamped and fixed through two groups of placing seats and the threaded adjusting rod. At the same time, the placing seat itself can rotate, and thus can drive the blade to rotate, so that the blade does not need to be disassembled, flipped and reinstalled during processing, improving the work efficiency.

[0008] Preferably, a buffer pad is arranged at the bottom end of the threaded adjusting rod, and a rubber pad is arranged on the inner wall of the placing seat;

[0009] The blade can be protected to avoid the situation that the extrusion force of the threaded adjusting rod is too large and causes damage to the blade.

[0010] Preferably, a fixed insertion rod is inserted into the top of the moving seat. The fixed insertion rod is arranged in a T-shape, and a plurality of limit insertion holes are annularly opened on the outer part of the rotating shaft rod. The bottom end of the fixed insertion rod is adapted to the limit insertion holes;

[0011] The fixed insertion rod can be inserted into the inner part of the limit insertion hole for limiting, so that the rotating shaft rod cannot drive the placement seat to continue rotating, and the placement seat can limit and fix the blade, making the processing of the blade more convenient.

[0012] Preferably, a support spring is sleeved outside the fixed insertion rod. One end of the support spring is fixedly connected to the end of the fixed insertion rod, and the other end of the support spring is fixedly connected to the top end of the moving seat.

[0013] The support spring can drive the fixed insertion rod to better insert into the inner part of the limit insertion hole, avoiding the situation that the fixed insertion rod moves and disengages from the inner part of the limit insertion hole.

[0014] Preferably, a sliding groove is formed at the top end of the support base, and a sliding block is arranged at the bottom end of the moving seat. The sliding block extends into the inner part of the sliding groove.

[0015] The moving seat can slide through the sliding block in the inner part of the sliding groove, so that the distance between the moving seat and the fixed seat can be adjusted, facilitating the clamping and processing of blades of different sizes and lengths.

[0016] Preferably, a threaded rotating rod is inserted into the side wall of the support base. The threaded rotating rod extends into the inner part of the sliding groove. The sliding block is sleeved outside the threaded rotating rod, and the sliding block is threadedly connected to the threaded rotating rod.

[0017] By rotating the threaded rotating rod, the threaded rotating rod can drive the sliding block to rotate, so that the sliding block drives the moving seat to move through the threaded structure. At the same time, the threaded structure has a self-locking structure, which can complete the limitation of the moving seat.

[0018] Preferably, a rotating disc is arranged at one end of the threaded rotating rod located outside the support base, and a rocker is arranged at the eccentric shaft position of the rotating disc.

[0019] It can enable personnel to rotate the threaded rotating rod by rotating the rotating disc outside, making the rotation of the threaded rotating rod more convenient.

[0020] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0021] 1. The present utility model can place the blade into the inner parts of two groups of placement seats, then complete the limitation of the blade by rotating the threaded adjusting rod. Subsequently, pull the fixed insertion rod so that the fixed insertion rod disengages from the inner part of the limit insertion hole. At this time, the blade can be directly rotated to complete the flipping of the blade, without the need for disassembly, flipping, and reinstallation, reducing the operation steps required for flipping, and thus improving the work efficiency.

[0022] 2. The utility model can drive the threaded rotating rod to rotate by rotating the rotating disc, and then drive the sliding block and the moving seat to move by the threaded rotating rod, so that the distance between the fixed seat and the moving seat can be adjusted, and thus the blades of different sizes and lengths can be clamped.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0029] Refer to Figures 1-4A clamping mechanism for blade processing as shown. A fixed seat 2 is provided on one side of the top end of the support base 1. Subsequently, a movable seat 3 is provided on the other side of the top end of the support base 1. A rotating shaft rod 4 is inserted into the top end of the movable seat 3. At the same time, a placing seat 5 is provided at the end of the rotating shaft rod 4. The placing seat 5 is arranged in a U-shape. At the same time, there are two groups of the placing seats 5. The other group of the placing seats 5 is movably connected to the fixed seat 2 through a rotating shaft, so that the placing seat 5 can rotate on the fixed seat 2 or the movable seat 3. Subsequently, a threaded adjusting rod 6 is inserted into the top end of the placing seat 5. A buffer pad 7 is provided at the bottom end of the threaded adjusting rod 6. At the same time, a rubber pad is provided on the inner wall of the placing seat 5. Subsequently, a fixed insertion rod 12 is inserted into the top end of the movable seat 3. The fixed insertion rod 12 is arranged in a T-shape. A plurality of limit insertion holes 14 are annularly formed on the outer part of the rotating shaft rod 4, so that the bottom end of the fixed insertion rod 12 is adapted to the limit insertion holes 14. At the same time, a support spring 13 is sleeved on the outer part of the fixed insertion rod 12, so that one end of the support spring 13 is fixedly connected to the end of the fixed insertion rod 12, and the other end of the support spring 13 is fixedly connected to the top end of the movable seat 3.

[0030] Specifically, the threaded rotating rod 10 in this embodiment will be described. Please refer to Figure 3 , a sliding groove 8 is formed at the top end of the support base 1. Subsequently, a sliding block 9 is provided at the bottom end of the movable seat 3. The sliding block 9 extends into the sliding groove 8. At the same time, a threaded rotating rod 10 is inserted into the side wall of the support base 1, so that the threaded rotating rod 10 extends into the sliding groove 8, and the sliding block 9 is sleeved on the outer part of the threaded rotating rod 10.

A rocker is provided at the eccentric shaft position of the rotating disc 11.

[0031] Working principle: When the utility model is in use, the position of the movable seat 3 can be adjusted according to the length of the blade. By rotating the rotating disc 11, the rotating disc 11 drives the threaded rotating rod 10 to rotate. The threaded rotating rod 10 drives the movable seat 3 to move through the sliding block 9, so as to adjust the distance between the two placing seats 5. The blade can be placed into the inside of the placing seat 5. Subsequently, the threaded adjusting rod 6 is rotated, so that the threaded adjusting rod 6 drives the buffer pad 7 to squeeze and clamp the end of the blade, and the fixation of the blade is completed.

[0032] When the blade needs to be flipped during the processing, the fixed insertion rod 12 can be pulled so that the end of the fixed insertion rod 12 is disengaged from the inside of the limit insertion hole 14, so that the rotating shaft rod 4 can drive the placement seat 5 to rotate, and then the blade is flipped. Subsequently, the fixed insertion rod 12 is released, so that the support spring 13 drives the end of the fixed insertion rod 12 to be inserted into the inside of the limit insertion hole 14 for limit fixation, and then the blade is fixed after flipping, making the processing of the blade more convenient.
