Description
Technical Field
[0001] This utility model relates to the field of grinding wheels, and more particularly to a flexible grinding wheel. Background Technology
[0002] A grinding wheel is a tool used for grinding processes, composed of abrasive grains, bonding agents, etc. It features high hardness and good wear resistance, enabling precision machining of various materials. Different grit sizes, hardnesses, and shapes of grinding wheels can be selected according to different processing requirements.
[0003] In the existing technology, flexible grinding wheels are often made of solid material, which results in a large overall weight of the grinding wheel. This significantly increases the load on the grinding machine spindle during operation, leading to high energy consumption. At the same time, due to the inertia caused by its own weight, the grinding wheel speed increases slowly and has poor acceleration performance, which directly restricts the improvement of grinding efficiency and makes it difficult to meet the needs of high-efficiency processing.
[0004] To address the above problems, a flexible grinding wheel is proposed. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a flexible grinding wheel, which aims to improve the problem that existing flexible grinding wheels are often solid, resulting in a large overall weight of the grinding wheel, which greatly increases the load on the grinding machine spindle during operation and leads to high energy consumption. At the same time, due to the inertia caused by its own weight, the grinding wheel speed increases slowly and the acceleration performance is poor, which directly restricts the improvement of grinding efficiency and makes it difficult to meet the needs of high-efficiency processing.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a bendable grinding wheel, including a mounting base, a motor fixedly connected to the outside of the mounting base, a rotating rod fixedly connected to the output end of the motor, a weight reduction and efficiency enhancement component provided at the end of the rotating rod away from the motor, and a cooling component provided on the outside of the mounting base;

A spring is sleeved on the outside of the push rod, and a stop block is fixedly connected to the end of the push rod away from the push plate. A liquid outlet is formed inside the mounting frame.
[0010] As a further description of the above technical solution:
[0011] The outer side of the rotating rod is rotatably connected to the inside of the support rod.
[0012] As a further description of the above technical solution:

[0022] This utility model has the following beneficial effects:
[0023] 1. In this utility model, a hollow design is formed by combining multiple fan-shaped arc-shaped fan blade blocks. Without affecting the overall strength and grinding performance, the weight of the grinding wheel is reduced, the load on the grinding machine spindle is reduced, energy consumption is reduced, the grinding wheel speed and acceleration performance are increased, and the grinding efficiency is improved.
[0024] 2. In this utility model, as the temperature rises, the thermally expanding material expands and pushes the push plate. The push plate drives the push rod to overcome the spring force, causing the stop block to move and open the outlet. The coolant in the cooling box flows out through the outlet groove and outlet to cool the grinding wheel. When the temperature drops, the thermally expanding material contracts, and the spring pushes the push plate and push rod to close the outlet, stopping the cooling. This achieves automatic release and closure of the coolant, precisely controlling the cooling process, effectively reducing the temperature of the grinding wheel, preventing performance degradation and workpiece quality problems caused by overheating, and extending the service life of the grinding wheel.

[0040] Specifically, the outer side of the rotating rod 20 is rotatably connected to the inside of the support rod 3 and the mounting base 1 to ensure that the rotating rod 20 can rotate flexibly and drive the weight reduction and efficiency enhancement components to operate smoothly under the drive of the motor 2; the outer side of the stop block 9 is slidably connected to the inside of the cooling box 6 to control the opening and closing of the liquid outlet 15 by sliding under the drive of the push rod 11, thereby regulating the flow of coolant; the outer side of the push plate 13 is slidably connected to the inner wall of the thin shell 10 to slide along the inner wall of the thin shell 10 under the expansion of the thermal expansion material 14 or the action of the spring 12, transmitting thrust or receiving the restoring force of the spring 12.

When the temperature rises, the thermal expansion material 14 expands due to heat and pushes the push plate 13. The push plate 13 drives the push rod 11 to overcome the elastic force of the spring 12, causing the stop block 9 to move and open the liquid outlet 8. The coolant in the cooling box 6 flows out through the liquid outlet 8 and the liquid outlet 15 to cool the grinding wheel. When the temperature drops, the thermal expansion material 14 contracts, and the spring 12 pushes the push plate 13 and the push rod 11, causing the stop block 9 to close the liquid outlet 8 and stop cooling.
