Numerically controlled lathe tool tower with overload protection structure

Abstract

This utility model discloses a CNC lathe turret with an overload protection structure, including a mounting base. A cylinder is fixedly installed in the middle of the top of the mounting base. This CNC lathe turret with an overload protection structure monitors the torque force of the tool head and other structures during operation using a torque sensor. When the torque force reaches the maximum preset value, the torque sensor feeds the information back to the control panel, thereby controlling the turret structure to stop working and activating an alarm that flashes red light and sounds a buzzer, thus reminding the operator of torque overload and requiring immediate action. The cylinder pushes the mounting plate up and down, thereby moving the turret body up and down, adjusting the height of the turret until the distance between the mounting plate and the mounting base reaches the preset value of the displacement sensor. At this point, the displacement sensor feeds the information back to the control panel, controlling the cylinder to stop working, thus achieving precise adjustment of the turret height.

[0002] The CNC lathe turret (also known as a CNC tool post) is a key component mounted on a CNC lathe. It is responsible for fixing the cutting tool and performing rapid tool changes to complete machining operations such as turning, drilling, and milling. However, existing CNC lathe turrets do not have torque overload protection and are not convenient for precise adjustment of the turret height according to usage requirements.

[0003] To address the aforementioned issues, a CNC lathe turret with an overload protection structure is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a CNC lathe turret with an overload protection structure to solve the problems mentioned in the background art.

[0006] The torque sensor monitors the torque force of the cutter head and other structures during operation. When the torque force reaches the maximum preset value, the torque sensor feeds back the information to the control panel, which then controls the turret structure to stop working and activates the alarm, releasing a flashing red light and emitting a buzzer sound to remind the operator that the torque force is overloaded and needs to be dealt with promptly. The cylinder pushes the mounting plate up and down, which in turn moves the turret body up and down, thereby adjusting the height of the turret body until the distance between the mounting plate and the mounting base reaches the preset value of the displacement sensor. At this point, the displacement sensor feeds back the information to the control panel, which then controls the cylinder to stop working, thus achieving precise adjustment of the turret height.

[0007] Preferably, a guide hole is provided on one side of the top of the mounting base, and a guide rod is inserted into the guide hole. The bottom end of the guide rod is fixedly connected to the mounting plate. The cooperation between the guide rod and the guide hole facilitates the stable movement of the mounting plate.

[0008] Preferably, both sides of the inner wall of the mounting base are provided with movable grooves, and movable blocks are slidably arranged inside the two movable grooves. The two movable blocks are fixedly connected to the mounting plate. The cooperation between the two movable blocks and the two movable grooves facilitates the stable movement of the mounting plate.

[0009] Preferably, a fixing block is fixedly provided at the bottom of both sides of the mounting base, and fixing holes are provided on both sides of the top of the two fixing blocks. The combination of the two fixing blocks and the four fixing holes facilitates the fixed installation of the device.

[0010] Preferably, the top of the mounting plate has first threaded holes on both sides, and the top of the tower body has second threaded holes on both sides. Fixing bolts are threaded between the two first threaded holes and the two second threaded holes respectively. Fixing the tower body with the two fixing bolts respectively is convenient for fixing and installing the tower body.

[0011] Preferably, the surface of the cutter head is provided with a plurality of mounting slots, and each of the plurality of mounting slots is provided with a cutter holder structure, thereby facilitating the installation of the cutter holder structure.

[0012] Preferably, the cylinder, displacement sensor, torque sensor, and alarm are all electrically connected to the control panel, and the control panel controls the cylinder, displacement sensor, torque sensor, and alarm to be powered on and start working.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The torque sensor monitors the torque force of the cutter head and other structures during operation. When the torque force reaches the maximum preset value, the torque sensor feeds back the information to the control panel, which then controls the turret structure to stop working and activates the alarm, releasing a flashing red light and emitting a buzzer sound to remind the operator that the torque force is overloaded and needs to be dealt with promptly. The cylinder pushes the mounting plate up and down, which in turn moves the turret body up and down, thereby adjusting the height of the turret body until the distance between the mounting plate and the mounting base reaches the preset value of the displacement sensor. At this point, the displacement sensor feeds back the information to the control panel, which then controls the cylinder to stop working, thus achieving precise adjustment of the turret height.

An alarm 11 is fixedly mounted on the outer side of the control panel 10. The torque sensor 16 monitors the torque force of the cutter head 12 and other structures during operation. When the torque force reaches the maximum preset value, the torque sensor 16 will feed the information back to the control panel 10, thereby controlling the turret structure to stop working and controlling the alarm 11 to be powered on, releasing a flashing red light and emitting a buzzer sound, thus reminding the staff that the torque force is overloaded and needs to be dealt with in time. The cylinder 2 pushes the mounting plate 3 to move up and down, thereby driving the tower body 4 to move up and down, thereby adjusting the height of the tower body 4 until the distance between the mounting plate 3 and the mounting base 1 reaches the preset value of the displacement sensor 5. The displacement sensor 5 will then feed the information back to the control panel 10, thereby controlling the cylinder 2 to stop working, thus achieving precise adjustment of the height of the tower body 4.

[0022] A guide hole 7 is provided on one side of the top of the mounting base 1. A guide rod 6 is inserted inside the guide hole 7.
