Description

TECHNICAL FIELD

[0001] The utility model relates to cigarette mechanical equipment technical field more specifically, it relates to a ball screw assembly frock of sand wheel reciprocating mechanism of shredding machine. BACKGROUND

[0002] In the production process of tobacco shredding machine, the sand wheel reciprocating mechanism of SQ34 type shredding machine relies on frequency conversion speed reducer motor to match ball screw to realize driving function. As the key transmission component, ball screw plays an important role in the long-term operation of the equipment. However, due to the continuous friction movement of the ball in the raceway, the ball will inevitably wear after a period of use. With the gradual decrease of the diameter of the ball, the gap between the ball and the raceway will increase. The increase of this gap not only affects the accuracy and stability of the transmission, but more seriously, in extreme cases, it may cause the ball screw pair to be stuck during operation. Once stuck, the equipment will be forced to stop, which will have a great negative impact on the continuous production of tobacco shredding operation.

[0003] In order to ensure the stable operation of the shredding machine and maintain stable shredding quality, it is necessary to replace and maintain the 210 balls in the ball screw nut regularly. However, when designing the ball screw, the manufacturer sets the ball diameter to 3mm and the raceway diameter to 4mm in order to ensure accurate transmission ratio and improve transmission flexibility. Although such design has certain performance guarantee, it puts forward very high requirements for the assembly of the ball.

[0004] In the actual assembly process, a series of strict and tedious steps and requirements must be followed. First of all, the ball screw, ball nut and ball itself must be thoroughly cleaned to ensure that the surface is free of water and oil. Because even a small amount of water or oil can cause the ball to fall unevenly during installation, resulting in gaps between the balls, making it impossible to install all 210 balls in the nut, ultimately causing the ball nut to be stuck and the assembly to fail. Secondly, the rotation direction of the sealing gasket at both ends of the ball nut must be consistent with that of the ball screw. If the rotation directions are not consistent, gaps will occur during assembly, which will directly affect the smooth installation of the ball. In addition, 210 balls need to be evenly installed into two guide tubes and guide holes, which requires the assembler to have high patience and precise operation skills. Moreover, when installing the guide tube, great attention must be paid to its installation position. Once installed incorrectly, the entire assembly process will be affected. Finally, the sealing gasket must be tightened with a jack screw during installation. Any looseness may cause subsequent assembly problems.

[0005] In order to complete such a complex and delicate assembly work, the assembly personnel need to keep the body down, bent over the waist for a long time on the operation platform. Moreover, the hands of the assembly personnel must be kept water and oil free, and 210 balls are put into the raceway between the nut and the screw one by one. Every time a ball is put in, the screw needs to be slowly rotated once, and the screw is slightly pulled back, so that each ball can be closely attached, and the gap between the balls is eliminated. Such operation mode is extremely tedious and laborious, and the technical level and experience of the assembly personnel are extremely high. According to the proficiency of different assembly personnel, the whole assembly work usually needs 30 to 60 minutes.
