1, change the position of the ball screw.

There are many reasons why the accuracy of the ball screw is not enough, because it is not placed in the right way and cannot be placed horizontally, which leads to the problem that the parts of the ball screw are inaccurate because of the influence of gravity. Therefore, it is necessary to change the placement mode of the ball screw, put the ball screw vertically, and let the original inside the ball screw move up and down due to the change of gravity, so that the original inside the ball screw will not rub against the outer wall of the ball screw because it is attached to the outer wall of the ball screw. It affects the accuracy of the original, so placing the ball screw vertically can solve the problem of gravity influence caused by placing the ball screw horizontally, and ensure that the accuracy will not be affected by gravity factors.

2, increase the correctness of the assembly method

Ball screws should be assembled by professional assemblers, not casually, but through scientific training. Without professional training, the assembly will lead to improper assembly and affect the accuracy of screws. In the assembly work of assembly technicians, it is necessary not only to meet strict requirements, but also to train and teach assembly workers scientific assembly methods according to the actual situation. To ensure that assembly technicians can use scientific assembly methods, it is necessary to put forward strict requirements for each assembly process and assembly personnel to ensure that the accuracy of the lead screw will not be affected by improper assembly.

3. Adopt the correct detection method.

In the process of testing the accuracy of the lead screw, the inspector should use a dial indicator with a magnetic meter base, take the linear guide slider of the workbench as the testing benchmark, unify the testing method, and ensure the clear testing accuracy. The most important problem is that the instruments for testing accuracy should be updated in time, and the inspectors who ensure the accuracy of ball screws must use the latest testing instruments. Because the previous testing instruments are difficult to adapt to the constant changes of ball screws, the latest testing instruments can ensure more accurate testing accuracy of ball screws, and unified scientific testing methods are needed to ensure the accuracy of ball screws with the most accurate values.

4, adopt the correct assembly process

When assembling the ball screw, strict and correct assembly technology should be adopted, and the dust on the ball screw should be cleaned in time. When dust enters the screw, it will wear the original parts inside the screw, resulting in the problem of insufficient precision of the screw. Therefore, it is necessary not only to improve the assembly process, but also to carry out dust removal in time. Ensure that the internal parts of the ball screw will not be worn due to the entry of dust, resulting in the problem of insufficient accuracy. Standardize the assembly process of the ball screw, educate the ball screw assembly personnel scientifically, strictly grasp the assembly requirements of each process, and strictly assemble the ball screw to ensure that there will be no problems in the assembly of the ball screw.

Problems of ball screw assembly;

1, the accuracy of ball screw is not enough.

The ball screw itself will be inspected when it is put into storage, and there is no quality problem in itself. The main problem of insufficient accuracy is that many ball screws are placed horizontally. An important problem of horizontal placement is that the main parts inside the ball screw will be deformed due to the direct force of gravity on the parts, or the parts will rub against the outer wall of the screw, resulting in wall sticking, which will lead to the influence of gravity on the parts of the ball screw.

2. Improper assembly will affect the accuracy of the lead screw.

Professional technicians should be used to assemble the screw, but many of them are not professional at present, and any mechanical worker can assemble the ball screw, so some problems will occur in the ball screw assembled by unprofessional people, or the original parts of the screw will be misplaced or damaged in the assembly process due to careless operation, which will directly affect the accuracy of the screw.

3. The detection method is incorrect.

In the inspection process of ball screw assembly equipment, many inspectors adopt different inspection standards, which leads to different precision of screw, and many inspectors' methods are incorrect, which will also lead to accuracy errors. When testing the ball screw, many people's own testing methods have shortcomings, but the inspectors do not understand the problems of their own testing instruments. There are still many people who use instruments that are not advanced enough, and some staff use instruments that are long ago, which leads to inaccurate detection.

4, the assembly process is wrong

At present, the assembly sequence of ball screws is wrong, which leads to the problem that the parallelism of ball screws exceeds the normal range. Moreover, in the process of drilling and reaming, dust is not treated, resulting in a large amount of dust entering the transmission surface of the ball screw pair, and the surface of the original will become less smooth because of dust wear, so the problem of the guide part will make it difficult for the internal original of the ball screw to maintain its previous working efficiency, leading to problems in accuracy.
