A kind of movable V-shaped thrust rod sealing cover crimping machine and its processing method

Abstract

The invention discloses a movable V-shaped thrust rod sealing cover withholding machine and belongs to the field of V-shaped thrust rod machining equipment. The movable V-shaped thrust rod sealing cover withholding machine is characterized in that an end cover riveting tool is connected to the lower portion of a hydraulic cylinder (1) and comprises fixing mechanisms (3) and a downward-pressing riveting mechanism, the power output end is positioned through the vertical fixing mechanisms (3) on the two sides, and an end cover (6) of a V-shaped thrust rod (2) is pressed through the downward-pressing riveting mechanism and riveted to the top of an upper ball base (7); the contact end face of the inner side of the lower portion of the downward-pressing riveting mechanism and the upper portion of the upper ball base (7) is provided with a plurality of elastic clamping riveting points. According to the movable V-shaped thrust rod sealing cover withholding machine, the movable end cover riveting tool is arranged on the lower portion of the hydraulic cylinder, can be positioned through the hydraulic cylinder and can also achieve the downward-pressing and riveting action through the elastic clamping riveting points, the movable V-shaped thrust rod sealing cover withholding machine is suitable for a long or short production line and suitable for large-scale production, and large-scale and standard production of products can be achieved more conveniently.

Description

technical field [0001] A movable V-shaped thrust rod sealing cover crimping machine and a processing method thereof belong to the field of V-shaped thrust rod processing equipment. Background technique [0002] At present, the mainstream V-shaped thrust rods mainly have two types in terms of structure, one is the global hinge type, and the other is the flange type joint bearing structure, and the flange type is widely used for its superior load-bearing performance. However, the sealability of the end cover of the V-shaped thrust rod of the joint bearing directly affects the service life of the joint ball assembly inside the ball seat housing on the V-shaped thrust rod, and restricts the reliability of the V-shaped thrust rod assembly. and usability.

Problems solved by technology

[0002] At present, the mainstream V-shaped thrust rods mainly have two types in terms of structure, one is the global hinge type, and the other is the flange type joint bearing structure, and the flange type is widely used for its superior load-bearing performance. However, the sealability of the end cover of the V-shaped thrust rod of the joint bearing directly affects the service life of the joint ball assembly inside the ball seat housing on the V-shaped thrust rod, and restricts the reliability of the V-shaped thrust rod assembly. and usability

[0003] In the field of commercial tractors at home and abroad, the sealing forms of the V-shaped thrust rod end cover are different, but most of the designs are very complicated and have poor reliability. For example, the V-shaped thrust rod end Six sealing protrusions are stamped out of the cylindrical surface of the cover, and the sealing end cover is pressed into the annular groove of the V-shaped thrust rod shell by the pressure of the hydraulic cylinder. During the process of pressing the V-shaped thrust rod end cover, the end The cover produces an elastic deformation under the action of the six stamping protrusions. Under the action of the elastic deformation of the end cover, the matching sealing gap between the inner hole of the sealing end cover and the outer shell of the upper ball seat will become larger, thus seriously affecting the sealing of the upper ball seat. The sealing performance and fit between the ball seat end cover and the shell, so in the long-term use process, the internal joint ball bearing will be corroded and lose its performance, which will directly lead to the failure of the V-shaped thrust rod assembly

[0004] For another example, the sealing method of the V-shaped thrust rod end cover adopted by the foreign ZF company is to complete the sealing by welding the upper ball seat and the sealing end cover of the V-shaped thrust rod. The damage of the shell is relatively large. Due to the high welding heat, the sealing ring of the end cover is also easy to burn during welding and sealing, which seriously affects the sealing performance of the end cover of the thrust rod.
