The crankshaft lathe is a type of specialized car.So what are the operating procedures for crankshaft machine tools?What are the characteristics of crankshaft machine tools?
Calcium operating procedures for crankshaft machine tools
1. The operator obtains the operating permit after passing the examination, and it is allowed to perform operations. The operator should be familiar with the performance, structure, etc. of the machine, and must abide by the safety and handover system.
2. Cheer in accordance with the instructions of Run, check the oil quality, whether the amount of oil is normal.
3. Check whether the manipulating handle is flexible and reliable, and whether the power supply, grounding device and protective device are good.
4. Check the functions of each button. Whether manual, automatic work and component work are normal.
5. When booting, run at low speed for 3 to 5 minutes to observe whether the operation of each department is normal.
6. It is forbidden to change the speed during the operation of the machine. The handle must be in place during the transmission to ensure that the internal gear is well meked.
7. Forbidden to step on the surface of the machine tool or place objects with the surface of the machine tool.It is strictly forbidden to repair the workpiece on the top of the machine tool and the table on the bed.
8. The sliding site of the machine tool is prohibited from putting wrenchs and other things.
9. When the machine tool is abnormal, parking should be parked immediately or notified the maintenance workers for maintenance.
10. After the work is completed, we must clean up the machine, keep tidy, and apply oil to prevent rust on the surface of the guide rail. Place each handle in a non -working position, cut off the power supply, and carefully implement the handover system.
Features of crankshaft machine tools
Compared with ordinary lathes, the crankshaft lathe has the following characteristics:
(1) Special cartridge, in addition to the chip head with a general card, this type of card also has the function of adjusting the eccentricity and orientation.The card is installed on the main axis of the machine tool. The sliding platform can be moved on the radial guide rail of the card body to adjust the eccentric amount.
(2) Large crankshaft lathes do not have a rear end conjugate, but supported by the same number of centers with the same number of necks in the lower part of the workpiece.
(3) Multi -blade processing semi -automatic circulation. In order to increase productivity, crankshaft lathes generally have front and rear blades, and the side of the rod neck and curve arm is processed.
The machine tool is processed automatically after starting, and automatic parking is automatically stopped after processing.The reason why the crankshaft lathe has these characteristics is that when designing and manufacturing, the crankshaft itself has a poor stiffness, the crankshaft connecting neck and the crankshaft rotation line do not coincide, and the curve -necked position angle is different.
Condition of crankshaft machine tools
The normal use of crankshaft lathes must meet the following conditions. The power supply voltage of the location where the machine is located is small, the ambient temperature is less than 30 shot, and the relative temperature is less than 80%.
1 The location environment requirements of the machine tool
The location of the machine tool should be far from the source of the vibration, and the impact of direct irradiation and thermal radiation of the sun should be avoided, and the effects of humidity and air flow should be avoided.If there is a source near the machine tool, the anti -vibration groove should be set around the machine tool.Otherwise, it will directly affect the processing accuracy and stability of the machine tool, which will make the electronic components in poor contact, fail, and affect the reliability of the machine.
2 Power requirements
Generally, crankshaft lathes are installed in the machine processing workshop. Not only are the ambient temperature changes, poor use conditions, but also a large number of electromechanical equipment, resulting in a large fluctuation of the power grid.Therefore, the location of the crankshaft lathe needs to be strictly controlled by the power supply voltage.The power supply voltage fluctuations must be within the allowable range and remain relatively stable.Otherwise it will affect the normal work of the CNC system.
3 temperature conditions
The ambient temperature of the crankshaft lathe is less than 30 shot, and the relative temperature is less than 80%.Generally speaking, the inside of the CNC electronics box is equipped with row or cold fans to keep the electronic component, especially the central processors working temperature is constant or the temperature difference changes very little.Excessive temperature and humidity will lead to a decrease in the life of the control system and the increase in failure.Increased temperature and humidity, the increase in dust will be bonded on the integrated circuit board and leads to short circuit.
4 Use machine tools in accordance with the instructions
When using machine tools, users are not allowed to change the parameters set by the manufacturer in the control system at will.The setting of these parameters is directly related to the dynamic characteristics of various components of the machine.Only the gap compensation parameter value can be adjusted according to the actual situation.
Users cannot replace machine tool accessories at will, such as hydraulic cards that exceed the specified in the manual.When the manufacturer sets the attachment, it will fully consider the matching of various link parameters.Blind replacement causes the non -matching of various link parameters, and even causes an unexpected accident.The pressure of hydraulic cards, hydraulic blade, hydraulic tail seats, and hydraulic oil cylinders shall not be increased arbitrarily within the stress range of stress.
