Spray painting manipulator is divided into electric spray painting and hydraulic spray painting,As the name implies,The electric painting manipulator is fully automatic operation,No labor required,The hydraulic painting manipulator requires manual assistance to complete the job。Therefore, the electric painting manipulator is compared with the hydraulic painting machine hand,The former has more advantages。
allowance: Standard deep groove ball bearings have ordinary grades,All andGB307.1Tally with。 play: Standard deep groove ball bearings haveC2、Standard(CN)、C3、C4andC5Interstage clearance,All andGB4604Tally with。
Single-phase ac motorprinciple: Description of single-phase capacitive motor:A single-phase motor has two windings,Namely, starting winding and running winding。The two windings differ in space90The degree of。A capacitor with a large capacity is connected in series on the starting winding,When the running winding and the starting winding pass through a single phase AC,Due to the action of the capacitor, the current in the starting winding is time ahead of the current in the running winding90Degree Angle,Get to the big value first。
PLCDuring the Siemens servo motor origin reset,withSThe type close to the origin regression method has high repetition accuracy,Ordinary photoelectric switches are difficult to meet,Optical fiber is preferred for origin sensors。The accuracy depends on the lead accuracy of the lead screw and the gear ratio of the servo。
Key points of lightning protection for Jinan Mingweft switching power supply
Advantages of automatic feeding robot: 1、Long working hours、High production efficiency,Can be repeated uninterrupted labor,The assembly line works normally。 2、Strong adaptability to the environment,Can be in dusty、Work in flammable and explosive environments。
Automatic manipulator features: 1、The arm adopts high-strength aluminum alloy structural beam with precision linear slide rail,Low noise、Long life。 2、900/1000/1100/1200The type is a double-cut structure。
RBCRolling bearings are an important tool for reducing friction in machinery,It is often used by businesses and factories。Bearing according to its frictional properties,It is divided into rolling bearings and plain bearings。Any parts are used regularly,They produce some pollutants on the surface,Bearings are no exception,In particular, the bearings are constantly rolling during work,Reduce friction between machines,This will inevitably cause some oil to enter the bearing,Therefore, bearings should be cleaned regularly,So how to clean the bearing?
TRFour repair process steps and limit speed of sliding bearing seat
The above bearing pressure is the value given at normal clearance,If the bearing uses very large clearance,Suitable for lower bearing pressures。The relationship between the bearing pressure and the allowable sliding speed is determined by the balance of heat generation and thermal radiation in the bearing。
