Description

Technical Field

[0001] The invention relates to the technical field of couplings, in particular to a coupling device for tool power transmission. Background Art

[0002] The coupling device commonly used in tool power transmission is a key component in the mechanical system that connects the shaft where the tool is located with the power source (such as a motor). It is responsible for transmitting motion and power. The coupling transmits the rotational power of the motor to the shaft where the tool is located, ensuring that the tool can rotate stably and efficiently, thereby completing processing tasks such as cutting and grinding. It also has a certain compensation capability and can cope with the offset between the two shafts caused by inaccurate manufacturing and installation or deformation and thermal expansion during operation, ensuring the continuity and stability of power transmission. The plum blossom coupling is a type of coupling device for tool power transmission. It has a simple structure, does not require lubrication, and is easy to maintain and inspect. The middle elastic body connection can absorb vibration and compensate for radial, angular and axial deviations. It is suitable for occasions with certain impact and vibration. It is mainly composed of a first half coupling, a second half coupling and a plum blossom elastic member. The first half coupling and the second half coupling are both fixed by bolts in two halves.

[0003] However, when the existing tool power transmission coupling device is in use, when the offset amplitude of the first half coupling and the second half coupling is too large, it is not easy to detect and remind. At the same time, the plum blossom-shaped elastic part will gradually wear out due to continuous friction, extrusion, etc. during long-term use. This wear will cause the thickness of the elastic part to become thinner and the elastic performance to decrease, thereby affecting the coupling's ability to absorb vibration and impact, making it difficult to detect and remind. In addition, the bolts on the first half coupling and the second half coupling will also loosen during use, making it difficult to detect and remind, and it is not stable and reliable, thereby affecting its use effect and life.

At this time, the movement of the first triangular plate 1602 can be detected by the distance sensor 1603 to remind the operator to perform inspection and maintenance, and at the same time, it can provide extrusion force; Furthermore, when the first triangular plate 1602 moves, the limiting rod 1002 can be driven to move through the second connecting block 1001 and inserted between two adjacent triangular blocks 1003, thereby temporarily limiting the first half 101 and the second half 102. Similarly, the looseness of the third half 1101 and the fourth half 1102 can be detected, and temporary limiting effect can be performed when looseness occurs, which is more stable and reliable.
