Embodiment 1

[0020] Such as figure 1 The large-angle tie rod head structure shown includes a ball head rod 1, a rotating rod 4, and a ball head shell 2. The ball head shell 2 is composed of two hemispherical shells 5 and the fixing parts 6 of the two hemispherical shells 5. The ball head The shell 2 is provided with the ball head cavity of the ball head rod 1 and the rotary rod head cavity of the rotary rod 4, the rotary rod cavity is arranged on the side of the ball head shell 2 rotary rod head cavity, the rotary rod head and the part connected with the rotary rod head The rotating rod is respectively located in the rotating rod head cavity and the rotating rod cavity, and an opening groove 7 is arranged on one side of the ball head cavity of the ball head shell 2, the ball head of the ball head rod 1 is located in the ball head cavity, and the ball head rod 1 is connected with the ball head Part of the rod body is located in the open groove 7, and the open groove 7 makes the ball head ro...

Embodiment 2

[0023] As the preferred design of embodiment 1, such as Figure 4 As shown, the opening groove 7 is a ridge-shaped opening groove. In order to avoid the ball head rod 1 and the tail end of the rotating rod 4 from being stuck in a straight line, the opening groove 7 is designed as a ridge shape, so that the ball head rod 1 is in the It is easy to deflect here.

Embodiment 3

[0025] As the preferred design of embodiment 1, such as figure 2 , 3 As shown, the hemispherical shell 5 is provided with a positioning post 8 and a positioning hole 9, and the two hemispherical shells are mutually positioned through the positioning post 8 and the positioning hole 9 and buckled into a spherical head shell 2, and then the thread and taper outside the rotating rod cavity are processed. This can ensure the concentricity of the inner cavity of the ball head shell. The outer wall of the ball head shell where the rotating rod cavity is located is set as a cone, and the taper thread is arranged on the cone. The taper nut 3 is sleeved on the taper thread, and the two hemispherical shells 5 lock and fix.

[0026] As a specific design, the rotating rod head is spherical or ellipsoidal, and the rotating rod head cavity is made into a corresponding shape to prevent the rotating rod from coming out. The two hemispherical shells block the rotating rod head so that the rot...

Abstract

The invention discloses a large-angle tie rod ball head structure. The large-angle tie rod ball head structure comprises a ball head rod, a rotating rod and a ball head shell, the ball head shell is composed of two hemispherical shells and fixing pieces of the two hemispherical shells, a ball head cavity of the ball head rod and a rotating rod head cavity of the rotating rod are formed in the ball head shell, and a rotating rod cavity is formed in one side of the rotating rod head cavity of the ball head shell; and the rotating rod head and the part, connected with the rotating rod head, of the rotating rod are located in the rotating rod head cavity and the rotating rod cavity respectively, an open groove is formed in one side of the ball head cavity of the ball head shell, a ball head of the ball head rod is located in the ball head cavity, the part, connected with the ball head, of the ball head rod is located in the open groove, and the ball head rod rotates and swings back and forth through the open groove. The large-angle tie rod ball head structure is simple in structure and easy to assemble, the two hemispherical shells are combined together to form the spherical shell, the open groove enables the ball head rod to rotate and swing back and forth, the rotating rod at the other end rotates, a large-angle concentric ball connecting structure is formed, and large-angle connecting rod movement is achieved.

Description

technical field [0001] The invention relates to a tie rod head structure, in particular to a tie rod head structure with a large angle. Background technique [0002] In order to prevent the ball head from falling out of the spherical shell in the existing pull rod ball head structure, the designed swingable angle is not large. However, in robots and new vehicles, a tie rod head with a large range of motion is required. This requirement creates a contradiction with the existing tie rod head structure, which cannot meet this demand. Innovation is required. Contents of the invention [0003] In order to overcome the shortcomings of the above-mentioned prior art, the present invention provides a large-angle tie rod ball head structure. [0004] In order to achieve the above-mentioned technical purpose, the technical solution adopted by the present invention is: a large-angle pull rod ball head structure, including a ball head rod, a rotating rod, and a ball head shell, [0...
