Các lỗi thường gặp của giá đỡ dao vuông điện của máy tiện CNC là gì
The electric square tool holder of the lathe is a relatively common tool changing device. With the automatic processing unit, numerical control processing can be realized. It is mainly divided into turret turret, hexagonal turret and square turret, etc. Because CNC lathes have higher requirements for the application of turrets, it is necessary to ensure that they have a level of sufficient cutting force and maintain good rigidity and stability. In addition, the rotary tool holder should ensure that the accuracy of repeated positioning meets expectations in practical applications. For example, it is necessary to set the end toothed plate as the precise positioning element of the entire structural system, and use the Hall switch to complete the signal transmission control, so as to reduce the adverse effects caused by mechanical contact and prolong the application time of the electric square tool holder of the CNC lathe.
In order to further improve the rationality and effectiveness of the application of the CNC lathe electric square tool holder, it is necessary to retrieve and analyze the fault problem in time, and make targeted judgments from the tool holder lock, tool body and tool holder, and maintenance personnel must formulate corresponding Matching measures to reduce the adverse effects of failures.
What are the common faults of the electric square tool holder of the CNC lathe
1 Tool holder lock failure
In the application process of the electric square tool rest of the CNC lathe, the more common problem is the lack of tightness of the tool rest. The reasons are as follows:
(1) The control circuit of the entire tool holder structure has hidden troubles, resulting in insufficient power supply, interruption of supply, and failure in the operation of the lathe;
(2) The locating pin at the actual locking position inside the tool holder is seriously worn, the components are seriously detached, and the gear matching degree is insufficient;
(3) In the application of CNC machine tools, the machine parameters are not reasonably set, especially the anti-lock time of the tool holder. The setting value is small, or the position of the sending plate is not calibrated accurately, which will affect the application of the tool holder lock. efficiency.
2 Tool body failure
For the application and operation of the electric square tool holder of the CNC lathe, the fault of the tool body is also relatively common, which is mainly manifested in the inability to effectively change the tool. Generally, its failure problems should be analyzed from the mechanical level and the electrical level. If there is vibration in the contact motor during the tool change operation, the fault may originate from the motor. If the power fault can be eliminated, it is generally caused by mechanical jamming inside the tool holder or damage to the mechanical components.
3 Tool holder failure
In the electric square tool rest of CNC lathes, the fault of the tool rest is also more common. First, if the power supply is insufficient or the switch position of the control box is wrong, the tool holder will not operate normally; secondly, the motor phase sequence is reversed, which will cause insufficient running reversal; finally, the clamping force of the corresponding components on the tool holder is large, and the will cause rotational imbalance.
