Description

Technical Field

[0001] This utility model belongs to the technical field of steering positioning components, and in particular relates to a simple steering positioning mechanism. Background Technology

[0002] Steering and positioning mechanisms are crucial components in mechanical equipment, vehicles, and other systems. They are primarily responsible for precisely controlling the steering direction of objects or vehicles and ensuring that they maintain accurate position and attitude during steering.

[0003] Its structure is usually quite complex and precise. It generally includes components such as steering knuckle, tie rod, ball joint, and kingpin. The steering knuckle is the key to connecting the wheel with other steering components. It is connected to the main body of the vehicle or equipment through the kingpin and can swing around the kingpin to achieve wheel steering. The tie rod is responsible for transmitting steering force, converting the rotation of the steering wheel into the steering action of the wheel. The ball joint ensures that the various components can be flexibly and stably connected and moved.

[0004] The problem with the above-mentioned technology is that many existing machines often need to rotate to a fixed angle, position and lock during operation, such as drill bushings and multi-directional planers. To achieve this function, indexing heads or servo motors with self-locking devices are often used, which are complex in structure, costly, and have large size and weight. Utility Model Content

[0005] In view of the problems existing in the prior art, this utility model provides a simple steering and positioning mechanism that can overcome or at least partially solve the above problems.

[0006] This utility model is implemented as follows: a simple steering and positioning mechanism includes a positioning seat, a sliding sleeve, a positioning ball, and a rotating shaft. The sliding sleeve is fitted onto the surface of the rotating shaft, the positioning ball is located between the positioning seat and the rotating shaft, the positioning seat is installed in the inner cavity of the sliding sleeve, the rotating shaft has a groove on its surface, a spherical hole on its surface, and a cylindrical pin on the surface of the sliding sleeve.

[0007] Preferably, the upper and lower parts of the groove are straight grooves, and the middle part of the groove is a spiral groove.

[0008] Preferably, the inner cavity of the sliding sleeve is divided into a first locking position, a rotating position, and a second locking position from top to bottom according to the difference in inner diameter.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] This invention utilizes a positioning seat, a sliding sleeve, a positioning ball, and a rotating shaft in cooperation. During operation, when the cylindrical pin on the sliding sleeve is located in the straight groove at the top of the rotating shaft, the second locking position of the sliding sleeve contacts the positioning ball, pressing the positioning ball into the spherical hole of the rotating shaft. The positioning ball and the sliding sleeve are then fixedly connected, achieving the positioning and locking of the rotating shaft. This solves the problem in the prior art where many mechanical actuators, such as drill sleeves and multi-directional planers, often require a fixed angle for positioning and locking during operation. To achieve this function, indexing heads or servo motors with self-locking devices are commonly used, resulting in complex structures, high costs, and large size and weight.

[0015] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0016] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0017] like Figures 1 to 3 As shown in the figure, a simple steering positioning mechanism provided by this utility model embodiment includes a positioning seat 1, a sliding sleeve 2, a positioning ball 3 and a rotating shaft 4. The sliding sleeve 2 is sleeved on the surface of the rotating shaft 4, the positioning ball 3 is located between the positioning seat 1 and the rotating shaft 4, the positioning seat 1 is installed in the inner cavity of the sliding sleeve 2, the surface of the rotating shaft 4 is provided with a groove 5, the surface of the rotating shaft 4 is provided with a spherical hole 6, and the surface of the sliding sleeve 2 is provided with a cylindrical pin 7.

[0018] The upper and lower parts of groove 5 are straight grooves, and the middle part of groove 5 is a spiral groove.

[0019] The inner cavity of the sliding sleeve 2 is divided into the first locking position 201, the rotating position 202 and the second locking position 203 from top to bottom according to the difference in inner diameter.

[0020] The working principle of this utility model:

[0021] During operation, when the cylindrical pin 7 on the sliding sleeve 2 is located in the straight groove at the upper part of the rotating shaft 4, the second locking position 203 of the sliding sleeve 2 contacts the positioning ball 3, pressing the positioning ball 3 into the spherical hole 6 of the rotating shaft 4. The positioning ball 3 is fixedly connected to the sliding sleeve 2, realizing the positioning and locking of the rotating shaft 4. This is the first working position. When the sliding sleeve 2 moves linearly downward under the drive of the cylinder or hydraulic cylinder, the cylindrical pin 7 on the sliding sleeve 2 enters the spiral groove from the straight groove of the rotating shaft 4. At the same time, the positioning ball 3 disengages from the second locking position 203 of the sliding sleeve 2 and enters the rotation position 202. The rotating shaft 4 begins to rotate. When the cylindrical pin 7 on the sliding sleeve 2 enters the straight groove at the lower part of the rotating shaft 4, the first locking position 201 of the sliding sleeve 2 contacts the positioning ball 3, pressing the positioning ball 3 into the spherical hole 6 of the rotating shaft 4. The positioning ball 3 and the sliding sleeve 2 cooperate and fix each other, realizing the positioning and locking of the rotating shaft 4, entering the second working position.

[0022] The sliding sleeve 2 moves up and down reciprocally, which can realize the circulation of the rotating shaft 4 between the first station and the second station.

[0023] In addition, by increasing the number of spiral grooves and straight grooves on the rotating shaft 4 (straight groove - spiral groove - straight groove - spiral groove - straight groove...), multiple workstations can be achieved.

[0024] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
