The installation insallation instructions are compiled for the purpose of adjusting and keeping the center(rotation axis) of two chucks within the required range,so that the equipment can meet the processing requirements of users.We hope that each equipment manufacturer can operate strictly according to this installation procedure.We also appreciate customer's communicating with us about the installation details,so that we can make improcement in time.Thank you.
1.Fix two products on the worktable accoding to the design requirements.As shown in the figure,the left chuck is named 'Main chuck' and the right is named 'Tail chuck'.
2.Screw down the fixing screws of the tail chuck.As shown in the figure,a hollow mandrel is clamped by the claw in the front of the tail chuck (Prepare a mandrel which is not too heavy in advance.Too heavy mandrel may affect the subsequent opeartions).The mandrel shall be 200-300mm long and have a diameter of 30-50mm.The magnetic base is fixed on the machine (not on the mounting table of tail chuck),with the pointer pointing to the position shown in the figure.Rotate the tail chuck manually,measure and ensure that the near end and far end runout of the mandrel is about 0.1. If the value is out of the specified scope, adjust the position of correspinding claw to meet the accuracy requirements.
Note:Measurement can also be conducted by inserting a long mandrel of size matching the center hole of tail chuck into the chuck center, and the mandrel shall be 1000-2000mm long.
3.Measure the ipper bus bar and side bus bar of mandrel
Measure the ipper bus bar of mandrel(namely the central upper bus bar of mandrel).The magnetic base is fixed on the machine (not on the mounting table of tail chuck),with the pointer pointing to the position shown in the figure.Move the entire mounting table to the left and right,measure and unsure that the upper bus bar value is below 0.05mm.Upper bus bar value exceeding the required scope can be adjusted by inserting copper sheet at two points on the bottom mounting surface of chuck.
Measure the side bus bar of mandrel(namely the central side bus bar of mandrel).The magnetic base is fixed on the machine(not on the mounting table of tail chuck), with the pointer pointing to the position shown in the figure,Move the entire mounting table to the left and right,measure and ensure that the side bus bar value is below 0.05mm.Side bus bar value out of the scope can be adjusted by slightly rotating the mounting base of chuck. After adjustment,check again if the bus bar accuracy meets standard.If the value is still out of the scope,repeat the adjustment till the error value of ipper bus bar and side bus bar of tail chuck is below 0.05mm.
Note:Measurement can also be conducted by inserting a long mandrel of size matching the center hole of tail chuck into the chuck center, and the mandrel shall be 1000-2000mm long.
4.With the center of tail chuck as the benchmark(the rotation center of tail chuck),measure the verticality of the reference plane on the back of the main chuck relative to the rotation center of tail chuck.
Measurement and adjustment method:magnetic base is fixed on the end face of the tail chuck with the pinter of dial indicator pointing to the position shown in the figure(reference plane of the main chuck).Slowly turn the tail chuck for one circle and ovserce the pointer reading of the dial indictor,The difference of the four points within the maximum transverse and vertical range measured shall be within 0.05mm.Error between two lateral points exceeding the required scope,if any, may be adjusted by inseting copper sheet at two points on the bottom mounting surface of chuck.Error between two vertical(up and down) points exceeding the required scope,if any, may be adjusted by inserting copper sheet at two points on the bottom mounting surface of chuck.Repeat the step several times till the error value is witnin 0.05mm.
5.With the center of tail chuck as the benchmark(the rotation center of tail chuck),measure the coaxiality between the rotation center of main chuck and the rotation center of tail chuck,that is the center of two chucks shall be of equal height.
Measurement and adjustment method:the magnetic base is fixed on the end face of the tail chuck,with the pointer of dial indiactor pointing to the position shown in the figure(inner wall of basic hole in main chuck).Slowly turn the tail chuck for one circle and observe the pinter reading of the dial indicator.The difference of the four points within the maximum transverse and vertical range measured shall be within 0.05mm.Error between two lteral points exceeding the required scope,if any,may be adjusted by slightly and transversely moving the mounting base of the main chuck.Error between two vertical(up and down) points exceeding the required scope,if any.may be adjusted by slightly and transversely moving the mounting base of the main chuck.
6.Measurement and adjustment of chuck centering accuracy.
Adjust the distance between two chucks between 500mm and 1000mm,and clamp the same mandrel.The mandrel shall be 1500-2000mm long and have a diameter of 30-50mm.The magnetic base is fixed on the machine,with the pointer pointing to the position shown in the figure(at the outer circle fo mandrel about 30mm away from the claw).Rotate the chuck and mandrel.The dial indicator respectively measures the mandrel runout at the position about 30mm away from the claw and mandrel runout of about 0.1mm is acceptable(in general,the clamping accuracy of claw has been adjusted before delivery of chuck.Users need to adjust the claw accuracy in case of customized product,extended claw or other special circumstances).If the valve is out of the specified scope,adjust the posiotion of corresponding claw to meet the accuracy requirements.
7.Check the overall accuracy.
Adjust the distance between two chucks between 500mm and 1000mm,and clamp the same mandrel.The magnetic base is fixed on the machine,with the pointer pointing to the posiotion shown in the figure(at the outer circle of mandrel about 30mm away from the main chuck claw).Move the tail chuck back and forth,so that the distance between the tail chuck and the main chuck is-100mm to 1000mm or so (tail chuck can be moved to the center hole fo the main chuck).The valve difference of the dial indicator pointer of about 0.05mm is acceptable .In the same away,point the dial indicator pointer to the outer circle of mandrel side,and the overall installation is qualified if the indicator value of dial indicator is about 0.05mm.If the value difference is still out of the scope,carefully check the details of the above steps and confrim if therre is any omission or if an acccuracy item is out of the scope.
