[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0018] Reference Figure 1-2 The present specific implementation adopts the following technical scheme: an automatic tightening device with multiple channels working in parallel, comprising a buttstock 1, a power supply assembly switch 2, an intelligent detection module 3, an auxiliary structural member 4, a DC reduction motor 5, a shaft connection 6 and a screwdriver head 7. An intelligent detection module 3 is arranged above the buttstock 1, a power supply assembly switch 2 is arranged on the inner side of the buttstock 1, the power supply assembly switch 2 is connected to the power supply assembly in the buttstock 1, a plurality of DC reduction motors 5 are arranged at the front end of the intelligent detection module 3 through the auxiliary structural member 4, the DC reduction motor 5 is connected to the screwdriver head 7 through the shaft connection 6, and the screwdriver head 7 is connected to the workpiece 8 to be tightened; the intelligent detection module 3 is connected to the DC reduction motor 5.
[0019] It is worth noting that the number of the DC reduction motors is 4 or 6.
[0020] The core components of this specific implementation method are a DC reduction motor and an electronic control board matched therewith. The working process is as follows: Figure 3 shown.
[0021] The working characteristics of the DC reduction motor in this specific implementation are as follows:
[0022] In steady state, its working torque-current characteristic curve is as follows: Figure 4 As shown;
[0023] When the motor working torque reaches the set value, the motor enters the stall state. The working current during stall is usually 3-5 times the normal working current. Its torque-current characteristic curve is as follows: Figure 5 shown.
[0024] The working principle of this specific implementation is as follows:
[0025] 1. Tightening judgment
[0026] In normal working mode, the equipment is powered on and the four-way tightening operation starts in parallel. However, due to the different initial positions of the bolt heads, there are differences in the order of finding the cap, tightening and tightening. When one way reaches the tightening state first, the DC reduction motor will stall when we set the torque. At this time, the current will increase sharply, and the intelligent detection module we developed will issue a command to stop tightening the way.
[0027] 2. Tighten in parallel
[0028] As described in step 1, after the first way is tightened, the second way and the third way will inevitably be tightened, until all four ways are finally tightened.
[0029] 3. Keep working
[0030] When all four lines are tightened, the tightening operation of the product is also completed, and the operator will start tightening the next product. At this time, he can reset the tightening equipment, and after resetting, the tightening equipment can start a new round of tightening operations. This cycle is repeated to achieve the effect of multi-line parallel automatic tightening operations.
[0031] This specific implementation method is widely used in the field of automobile manufacturing: for tightening automobile parts, such as high-voltage boxes and control boxes. In the field of aerospace: for assembly and maintenance of aerospace equipment. In the field of electric power energy: for assembly of electric power energy products, such as power protection devices, harmonic detection devices, etc. In the field of mechanical manufacturing: for assembly and maintenance of various mechanical equipment. In the field of construction: for tightening operations in construction, such as bolt tightening, etc.
[0032] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
