Description

Technical Field

[0001] The invention belongs to the technical field of turret trial operation, and in particular relates to a turret trial operation control system for a numerically controlled lathe. Background Art

[0002] As the core component of a CNC lathe, the assembly and operation of the turret require very strong professionalism. It is not possible to assemble the turret on a simple workbench and then install the newly developed turret on the lathe for operation as in the traditional assembly. If there is a problem with the newly developed turret, it is not only inconvenient to repair it on the lathe, but also cannot guarantee the safety of the operator. Therefore, after the turret is assembled, it must first be tested on a specific test platform with a specific test system. Only after confirming that the whole set of actions are correct can it be installed on the lathe for use. However, the current system has a single function and the detection effect is not comprehensive. There are great limitations in actual use and there is room for improvement. Summary of the invention

[0003] The object of the present invention is to provide a turret test operation control system for a CNC lathe, so as to solve the problems of single function and poor detection effect of the existing control system proposed in the above background technology.

[0006] The control box is equipped with a turret servo driver, an IO control circuit board, a power-on brake circuit board, a 220V distribution circuit board and electrical control components. This control system is mainly used to detect the tool change process of the turret and whether the hydraulic release and locking signals of the turret can be detected;

[0007] The turret servo driver is connected to the spindle servo motor, and the servo driver drives the spindle servo motor to perform the tool change operation of the turret. After the tool change is completed, the proximity switch is used to detect whether the turret is hydraulically locked, and the servo motor stops to complete the entire tool change process. A path optimization module is provided in the turret servo driver, which is used to calculate the optimal path according to the target position and the current position, so as to control the spindle servo motor to change the tool with the shortest path when changing the tool, thereby improving the tool change speed;

[0008] The electrical control component is provided with a detection module, which is used to detect whether the turret is hydraulically locked; the turret running-in platform is also provided with a hydraulic module, which is used to lock and separate the turret.

[0009] As a preferred technical solution in the present invention, the turret servo driver is also connected to an alarm module, which is an audible and visual alarm.

[0010] As a preferred technical solution in the present invention, the detection module is a proximity switch.

[0011] As a preferred technical solution in the present invention, the turret servo driver is also connected to a program editing module, which writes a turret tool changing logic control program, and the turret servo driver controls the spindle servo motor to complete the tool changing action.

[0012] As a preferred technical solution in the present invention, the operating steps of the control system are as follows:

[0013] Step 1: The turret servo drive calculates the optimal path based on the path optimization module, and at the same time the hydraulic module is released;

[0014] Step 2: The proximity switch detects whether the hydraulic module locks the turret. If it is still locked, return to step 1 to continue to loosen it through the hydraulic module. If the loosening is completed, start the servo motor to drive the turret to perform tool change operation;

[0015] Step 3: After the tool change is completed, the proximity switch is used to detect whether the tool change position of the turret is in place. If not, return to step 2, and continue to adjust the position of the turret by rotating the servo motor. Then, the proximity switch is used to detect whether the hydraulic module is locked on the turret. If it is in a loose state, continue to start the hydraulic module until the proximity switch detects that the hydraulic module has completed locking the turret.

[0016] Step 4: The turret servo driver and servo motor are turned off synchronously to complete the tool change.

[0017] As a preferred technical solution in the present invention, the servo motor realizes tool change of the turret by switching forward rotation or reverse rotation.

[0018] As a preferred technical solution in the present invention, after the turret servo driver is started, a turret servo driver preparation check will be performed, and when an error occurs during the check, the turret servo driver will generate an alarm.

[0019] As a preferred technical solution in the present invention, the priority of the turret servo driver is lower than that of the IO control circuit board and the power-on brake circuit board, and the priority of the 220V branch circuit board and the electrical control components are lower than that of the turret servo driver.
