Description

Technical Field

[0001] This utility model belongs to the field of fan polishing technology, specifically relating to a fan polishing device for fan production and processing. Background Technology

[0002] A fan is a device that uses mechanically driven blades to rotate, accelerating airflow to achieve ventilation, cooling, or heat dissipation. Blade polishing is a key process in fan production. If there are burrs, unevenness, or processing marks on the surface of the blades, it will increase airflow resistance, resulting in reduced airflow and increased noise. Polishing can eliminate these defects and make the airflow smoother.

[0003] Existing grinding equipment lacks an adaptive design for the curved surface of fan blades, making it difficult for the polished surface to conform to the complex contours during the grinding process. This easily leads to uneven grinding or excessive wear in local areas. Single-point contact or fixed-path grinding methods cannot cover the complex curved surface structure of fan blades, resulting in limited processing range and insufficient flexibility. This makes it difficult to meet the needs of rapid switching between multiple fan blade models, ultimately restricting overall production efficiency.

[0004] Therefore, existing fan polishing devices suffer from poor adaptability to polishing curved fan blade surfaces and insufficient polishing efficiency and flexibility. Utility Model Content

[0005] In order to overcome the problems of poor adaptability to grinding curved fan blade surfaces and insufficient grinding efficiency and flexibility of existing fan grinding devices, a fan grinding device for fan manufacturing and processing is proposed.

[0006] The technical solution of this utility model is as follows: a fan polishing device for fan manufacturing and processing, including a base; it also includes an annular frame and a fixed bracket. A sliding member is slidably arranged on the upper part of the base. Two annular frames are fixedly connected to the left end of the sliding member. Two polishing machine support frames are rotatably arranged on the left end of the annular frames. Limiting rods are fixedly connected to the inner walls of the front and rear ends of the annular frames. A fixed bracket is fixedly connected to the lower end of the inner wall of the polishing machine support frame. An electric rotating roller and a second rotating roller are rotatably arranged on the upper and lower ends of the polishing machine support frame. A polishing belt is sleeved on the outer wall of the electric rotating roller and the second rotating roller. Fixed columns are fixedly connected to the upper and lower ends of the electric rotating roller. The fixed columns are slidably arranged on the outer wall of the limiting rods. A first arc-shaped baffle and a second arc-shaped baffle are slidably arranged on the fixed bracket. The distance between the first arc-shaped baffle and the second arc-shaped baffle is adjusted by rotating the screw thread. The ends of the first arc-shaped baffle and the second arc-shaped baffle that are far apart from each other are in contact with the inner wall of the polishing belt. A clamping member is fixedly connected to the upper end of the base.

[0007] Preferably, a slide rail is fixedly connected to the upper end of the base, and a slider is slidably provided on the left end of the slide rail, with the left end of the slider and the sliding component being fixedly connected to each other.

[0008] Preferably, a spring is fitted on the outer wall of the limiting rod, with one end of the spring fitting against the outer wall of the fixing post and the other end fixed to the inner walls of the front and rear ends of the annular frame.

[0009] Preferably, the upper end of the grinding machine support frame is provided with a first groove, and the upper and lower ends of the second roller are provided with rotating handles.

[0010] Preferably, two first limiting posts and two second limiting posts are slidably arranged at the front and rear ends of the fixed bracket, respectively. The rear ends of the two first limiting posts and the front ends of the first arc-shaped baffle are fixedly connected to each other, and the front ends of the two second limiting posts and the rear ends of the second arc-shaped baffle are fixedly connected to each other.

[0011] Preferably, a first threaded post is fixedly connected to the front end of the first arc-shaped baffle, a second threaded post is fixedly connected to the rear end of the second arc-shaped baffle, and a double-threaded sleeve is rotatably mounted on the fixed bracket.

[0012] Preferably, the first threaded post and the second threaded post are threadedly installed at the front and rear ends of the double-threaded sleeve, respectively. The outer wall of the first threaded post is threaded with a first nut, and the outer wall of the second threaded post is threaded with a second nut.

[0013] The beneficial effects of this utility model are as follows: the fan blade is placed on the clamping component and clamped. The first arc-shaped baffle and the second arc-shaped baffle are connected by a threaded structure to adjust the distance between them. Thus, during the grinding process, the polishing belt can adapt to the arc-shaped surface of the fan blade by its own deformation and the shape limitation of the first arc-shaped baffle and the second arc-shaped baffle. Furthermore, the rotation and sliding of the two grinding machine support frames on the limiting rod can enable the grinding device to self-adapt during operation, thereby improving the overall grinding efficiency.

Furthermore, by the rotation and sliding of the two polishing machine support frames 3 on the limiting rod 202, the polishing device can be adaptively adjusted during operation, thereby improving the overall polishing efficiency.

[0022] Please see Figures 1-2In this embodiment, a slide rail 102 is fixedly connected to the upper end of the base 1, and a slider 103 is slidably arranged on the left end of the slide rail 102. The left end of the slider 103 and the slider 2 are fixedly connected to each other.
