    机床在碰撞后不能移动怎么回事?
    2020-1-16 14:50:56

      当加工中心执行加工程序时,第一刀具加工正常,但第二刀具更换后,主轴与工件在加工过程中发生碰撞,机床在碰撞后不能移动。这是怎么回事?

      When the machining center executes the machining program, the machining of the first tool is normal, but after the replacement of the second tool, the spindle collides with the workpiece during the machining process, and the machine cannot move after the collision. What's going on?

      上述现象可能与驱动控制面板的电源和行程开关有关。打开控制柜,清除灰尘,仔细检查线路、连接器和部件是否有异常。经过测试,我发现是X, Y, Z。

      The above phenomena may be related to the power supply and travel switch of the drive control panel. Open the control cabinet, remove the dust, and carefully check the circuit, connector and components for abnormalities. After testing, I found it was x, y, Z.

      轴驱动板上的gtk457功率晶体管烧坏了。更换损坏的电源管后,X, Y, Z。

      The gtk457 power transistor on the shaft drive board is burnt out. After replacing the damaged power tube, x, y, Z.

      轴可以向三个方向移动,可以进行手动换刀,但不能在执行加工指令时进行。在机器返回零之后,您可以替换第一个工具,但是在处理过程中不能替换该工具。根据经验,按顺序运行以下测试。

      The axis can be moved in three directions, and manual tool change can be carried out, but it can not be carried out when the machining command is executed. After the machine returns zero, you can replace the first tool, but you cannot replace the tool during processing. Based on experience, run the following tests in sequence.

      1. TM 4通过伺服检测证明z轴为±0.02。它通常意味着X = 0。009-0.000mm, Y = 0。009年?

      1. TM 4 proves that the z-axis is ± 0.02 through servo detection. It usually means x = 0. 009-0.000mm, Y = 0。 009 years?

      0.000mm, Z在0.009到0.000mm之间。这表示在加工完第一个工具后替换第二个工具之前,机器不会返回到零。

      0.000mm, Z is between 0.009 and 0.000mm. This means that the machine will not return to zero until the first tool is machined and the second tool is replaced.

      坐标值不在0.009到0.000mm之间。改变Z轴检测精度参数(也称机器定位精度)后,设Z = 0。050

      The coordinate value is not between 0.009 and 0.000mm. After changing the z-axis detection accuracy parameter (also known as machine positioning accuracy), set z = 0. 050

      嗯,这台机器运转良好。然而,在机器上,第二天在反向时,机床上却出现了X、Y正、Y负、Z正、Z负的覆盖。

      Well, this machine works well. However, on the machine, in the reverse direction the next day, the coverage of X, y positive, y negative, Z positive and Z negative appears on the machine.

      2. 检查机器上的电路和急停按钮,工作正常,检查所有的保险丝,即使交换后,确保FU4(在强盒中)被烧坏,显示的功率仍然是X轴、Y轴和Z轴。

      2. Check the circuit and emergency stop button on the machine to ensure they work normally. Check all fuses. Even after switching, make sure fu4 (in the strong box) is burnt out, and the displayed power is still x-axis, Y-axis and z-axis.

      轴超速。请检查电源板上的24v电压。输出正常,检查z轴限位开关没有24v电压

      Shaft overspeed. Please check the 24V voltage on the power board. The output is normal. Check that the z-axis limit switch has no 24V voltage

      检查电压输入后,可以看到这是一个松动的保险丝,当您在上一步更换保险丝时,在拧紧保险丝后,机器的电源运行正常,但是有一个工具在工作时仍在开关我。根据经验,关掉机器5分钟

      After checking the voltage input, it can be seen that this is a loose fuse. When you replace the fuse in the previous step, after tightening the fuse, the power supply of the machine operates normally, but there is a tool that is still switching me when it is working. According to experience, turn off the machine for 5 minutes

      当电源再次打开,系统复位时,工具号也会随之改变。机器的通讯正常。

      When the power is turned on again and the system is reset, the tool number will change accordingly. The communication of the machine is normal.
