Anonymous users2024-01-24Most ordinary lathes are manually drilled, and some models can be automatically drilled by driving the tailstock with a large pallet. A stepper motor is installed on the original rocker to achieve automatic feeding, and the tailstock of heavy machine tools can be automatically fed. Shenyang No. 1 Machine Tool Factory CA6140 horizontal lathe tailstock feed automation transformation, transformation parameters:
The output speed of the reducer is 139N·m, and after the motor power is transformed, the automatic feed function is used when processing batch parts, and manual feed (crank handwheel is realized) when processing non-batch partsThe tailstock feed is changed to motor plus reducer drive, and the motor drives the reducer to transmit the power to the top feed screw through the clutch to achieve feed. When an automatic feed is not required, the clutch is disconnected and the operator can turn the lead screw by the handwheel to achieve the center feed.
The lathe tailstock mechanism of automatic feeding, comprising: support body, and the driving mechanism and toggle mechanism that are installed on the support body, the driving mechanism and the toggle mechanism are connected by the fork lever, the driving mechanism is driven by the power unit, the driving mechanism drives the drill bit action, and the driving mechanism can drive the driving gear forward rotation and reverse; The toggle mechanism comprises a lever that is slidably arranged, and two fork levers are respectively positioned at the two ends of the driving gear outside; One end of the drive shaft is provided with a screw rod, and the screw sleeve that connects the bending rod is sleeved on the screw rod; The fork is connected with the lever by the first pivot, and the fork is connected with the chain rod by the second pivot, and the fork rotates by the third pivot; The two ends of the chain are respectively connected with the free end of the chain rod and the free end of the bending rod, and the free end of the chain rod and the free end of the bending rod can be topped together; One end of the first spring is fixedly connected to the pendulum at the second rotating shaft, and the other end of the first spring is fixedly connected to the fixed block. The lever is also provided with a bump, and the bump is connected with the stopping mechanism.
The tailstock of ordinary lathes can not move automatically, and it needs to be drilled automatically or can be modified to give it power, so there is a tailstock changing automatic feed punching device, which is sold on the market, and it can not be advertised on the Internet. The effect is good, there is a video you can watch.
The manual feed of the tailstock is changed to a motor plus reducer drive, and the motor drives the reducer to transmit the power to the top feed screw through the clutch to achieve feed. When an automatic feed is not required, the clutch is disconnected and the operator can turn the lead screw by the handwheel to achieve the center feed.
The tailstock of an ordinary lathe cannot be moved automatically, it needs to be drilled automatically or it can be modified to give it power.
The lathe tailstock pressure plate can not be used iron plate, this is a strict requirement.
The tailstock lead screw thread is severely worn.
The threads of the platen screw are worn. >>>More
