Description

Technical Field

[0001] This utility model relates to the field of polishing fixture technology, specifically a bidirectional polishing clamping fixture for the inner hole of a blocking wheel. Background Technology

[0002] Photovoltaic (PV) obstruction wheels are crucial devices in PV systems, protecting modules, optimizing power generation efficiency, and coping with extreme environments. Addressing power loss caused by shading of PV modules, obstruction wheels actively avoid obstacles by dynamically adjusting the module angle. For example, some devices employ a worm gear drive mechanism, using a motor to move the mounting base along a semi-circular track, constantly changing the tilt angle of the PV panels to ensure sunlight always hits perpendicularly, thus improving power generation efficiency. When covered by obstructions (such as bird droppings or snow), the system can quickly adjust to a vertical position, reducing the shaded area. Simultaneously, in conjunction with the adjustment function of the micro-inverter, it ensures the unshaded portion operates independently, preventing a decrease in overall power generation efficiency. During manufacturing, obstruction wheels require polishing to ensure assembly precision.

[0003] However, the inner diameter of common blocking wheels varies. When grinding and polishing their inner holes, existing polishing fixtures require the blocking wheels to be clamped multiple times, which affects the polishing accuracy and has low polishing efficiency. Utility Model Content

[0004] The purpose of this invention is to address the problem of low polishing precision and efficiency of existing baffle wheel inner hole polishing fixtures.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

A positioning ring is fixedly connected to the top of the through hole. Several positioning platforms are fixedly connected to the top of the positioning ring vertically along its axis. A dust cover is fixedly connected to the bottom and the outer side of the top of the through hole. A pair of limiting mechanisms are symmetrically arranged on both sides of the positioning ring. An upper polishing mechanism and a lower polishing mechanism are respectively arranged at the top and bottom of the frame. The lower polishing mechanism includes a lower mounting frame. A lower lifting mechanism is fixedly connected to the side wall of the lower mounting frame. A lower polishing motor is fixedly connected to the lifting platform of the lower lifting mechanism. The shaft of the lower polishing motor passes through the dust cover and is detachably connected to a lower polishing head. An exhaust port is opened on the side wall of the dust cover.

[0007] Furthermore, the upper grinding mechanism includes an upper mounting frame, an upper lifting mechanism is fixedly connected to the side wall of the upper mounting frame, an upper grinding motor is fixedly connected to the lifting platform of the upper lifting mechanism, and an upper grinding head is detachably connected to the rotating shaft of the upper grinding motor.

[0021] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-5The bidirectional polishing clamping fixture for the inner hole of the blocking wheel in this embodiment includes a frame 1. A through hole 9 is opened at the center of the top of the frame 1. A positioning ring 2 is fixedly connected to the top of the through hole 9. Several positioning platforms 3 are fixedly connected to the top of the positioning ring 2 vertically along its axis. Dust covers 14 are fixedly connected to the bottom and the outer side of the top of the through hole 9. A pair of limiting mechanisms 4 are symmetrically arranged on two sides of the positioning ring 2 for limiting and fixing the blocking wheel. An upper grinding mechanism and a lower grinding mechanism are respectively arranged at the top and bottom of the frame 1 for simultaneously grinding the upper and lower ends of the inner hole of the blocking wheel. The lower grinding mechanism includes a lower mounting frame 10, a lower lifting mechanism 11 is fixedly connected to the side wall of the lower mounting frame 10, a lower grinding motor 12 is fixedly connected to the lifting platform of the lower lifting mechanism 11, and a lower grinding head 13 is detachably connected to the rotating shaft of the lower grinding motor 12 through a dust cover 14. An exhaust port 15 is provided on the side wall of the dust cover 14. The upper grinding mechanism includes an upper mounting frame 5, an upper lifting mechanism 6 is fixedly connected to the side wall of the upper mounting frame 5, an upper grinding motor 7 is fixedly connected to the lifting platform of the upper lifting mechanism 6, and an upper grinding head 8 is detachably connected to the rotating shaft of the upper grinding motor 7. During polishing, the blocking wheel is placed between the positioning platforms 3 on top of the positioning ring 2 and positioned by the positioning platforms 3. Then, the blocking wheel is fixed by the limiting mechanisms 4 on both sides. At this time, the upper grinding motor 7 and the upper grinding head 8 are driven to move downward to the polishing position by the lifting mechanism 6 at the top. During the movement, the upper grinding motor 7 drives the upper grinding head 8 to start rotating, polishing the larger diameter part at the top of the inner hole of the blocking wheel. At the same time, the lower grinding mechanism repeats the above steps to polish the larger diameter part at the bottom of the inner hole of the blocking wheel. After the end of the blocking wheel is polished, The upper grinding motor 7 and the lower grinding motor 12 are reset, and then the upper grinding head 8, which matches the diameter of the middle part of the inner hole of the blocking wheel, is replaced. The above steps are repeated to grind the middle part of the inner hole of the blocking wheel. This achieves bidirectional synchronous grinding and polishing of the inner holes of the blocking wheel with different diameters, effectively improving the polishing accuracy and efficiency of the polishing wheel. During grinding, the dust in the inner hole of the blocking wheel falls into the dust cover 14 along the through hole 9. Then, the dust in the dust cover 14 is sucked out through the exhaust port 15, and the dust is collected and treated in a centralized manner to prevent it from falling into the lower grinding motor 12 along the through hole 9 and affecting its service life.

[0023] The upper grinding head 8, the lower grinding head 13, the through hole 9, and the positioning ring 2 are coaxially arranged.

[0024] The limiting mechanism 4 includes a limiting seat 401, a limiting cylinder 402 is horizontally fixedly connected to the side wall of the limiting seat 401, and an arc-shaped limiting block 403 is fixedly connected to the piston rod of the limiting cylinder 402. During limiting, the arc-shaped limiting block 403 is driven by the limiting cylinder 402 to move to the limiting position, thereby limiting the outer side wall of the blocking wheel.

[0025] An upper limit rod 404 is fixedly connected to the top of the arc-shaped limiting block 403. When the arc-shaped limiting block 403 moves, it drives the upper limit rod 404 at its top to move synchronously, thereby limiting the blocking wheel in the vertical direction and preventing it from moving along with the upper grinding head 8 and the lower grinding head 13 when they are raised and lowered, thus further improving the grinding and polishing accuracy.

[0026] Several rollers are rotatably connected to the bottom of the frame 1. The presence of rollers facilitates the adjustment of the position of the frame 1, improving its operational flexibility.

[0027] Working principle: During grinding, the blocking wheel is placed between the positioning platforms 3 on top of the positioning ring 2, and positioned by the positioning platforms 3. Then, the blocking wheel is limited and fixed by the limiting mechanisms 4 on both sides. At this time, the upper grinding motor 7 and the upper grinding head 8 are driven by the upper lifting mechanism 6 to move downward to the grinding position. During the movement, the upper grinding motor 7 drives the upper grinding head 8 to start rotating, grinding and polishing the larger diameter part at the top of the inner hole of the blocking wheel. At the same time, the lower grinding mechanism repeats the above steps to grind and polish the larger diameter part at the bottom of the inner hole of the blocking wheel. After the end of the blocking wheel is polished... After completion, the upper grinding motor 7 and the lower grinding motor 12 are reset. Then, the upper grinding head 8, which matches the diameter of the middle part of the inner hole of the blocking wheel, is replaced, and the above steps are repeated to grind the middle part of the inner hole of the blocking wheel. This achieves bidirectional synchronous grinding and polishing of the inner holes of the blocking wheel with different diameters, effectively improving the polishing accuracy and efficiency of the polishing wheel. During grinding, the dust in the inner hole of the blocking wheel falls into the dust cover 14 along the through hole 9. Then, the dust in the dust cover 14 is sucked out through the exhaust port 15, and the dust is collected and treated in a centralized manner to prevent it from falling into the lower grinding motor 12 along the through hole 9 and affecting its service life.
