Description

Technical Field

[0001] This utility model relates to the field of mechanical transmission connection components, specifically to a mechanism that relies on mechanical cooperation to achieve rotation and fixed angle. Background Technology

[0002] A mechanism is a combination of two or more components that are connected by movement to achieve a specified motion. Most existing rotary motions rely on gear transmission. However, gear transmission has the disadvantage of not being able to lock itself. Under load or external force, it is prone to reverse rotation, which leads to positioning failure. An additional brake or clutch is required to fix the angle, which increases the complexity and cost of the system. Moreover, gear transmission itself cannot directly achieve indexing positioning. Therefore, it is urgent to improve it. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings and deficiencies of the existing technology by providing a simple, reasonably designed, and easy-to-use mechanism that achieves rotation and fixed angle through mechanical cooperation. It is driven by intermittent rotation to achieve fixed angle rotation and uses a reinforced structure to achieve angle positioning.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: it includes a base and a central shaft, with the central shaft threaded through the upper end of the base via a bearing; it also includes:

[0005] The rotating component is sleeved and fixed on the central shaft and is located inside the base; several arc-shaped grooves and strip-shaped grooves are evenly distributed on the outer ring wall of the rotating component, and the arc-shaped grooves and strip-shaped grooves are spaced apart.

[0006] The drive motor is fixedly mounted on the upper side of the base and is located on the right side of the central shaft; the output end of the drive motor passes through the top plate of the base and is provided with a drive shaft.

[0007] A rotating platform, wherein the rotating platform is sleeved and fixed on the drive shaft, and the outer ring wall of the rotating platform is engaged with the arc-shaped groove;

[0008] A rotating component is sleeved and fixed on a drive shaft, and the rotating component is located on the lower side of a rotating table. A drive rod is provided on the rotating component, and the drive rod slides through a strip groove.

[0009] The above technical solution is designed so that the drive motor is started to make the rotating table and rotating parts rotate. When the rotating table rotates and engages with the arc-shaped groove, the rotating parts are in a fixed state. When the rotating parts rotate and the drive rod is placed in the strip groove to rotate, the rotating parts are driven to rotate, causing the central shaft to rotate.

[0010] As a further improvement of this utility model, the upper surface of the rotating platform is flush with the upper surface of the rotating component, and the lower surface of the rotating platform is flush with the lower surface of the rotating component.

[0011] The above technical solution design allows the outer ring wall of the rotating platform to fit into the arc-shaped groove.

[0012] As a further improvement of this utility model, a frustum is sleeved and fixed on the central shaft, and the frustum is located on the upper side of the base; several protrusions are fixedly arranged circumferentially on the outer ring wall of the frustum; an ejection limiting component is provided on the lower side of the protrusions, the ejection limiting component comprising:

[0013] A support block is fixedly mounted on the inner top surface of the base and is located on the left side of the central axis; a movable block is slidably mounted on the front side of the support block.

[0014] A rotary motor is fixedly mounted on the rear side of the support block, and the output shaft of the rotary motor passes through the support block and is fitted with and fixed with an eccentric wheel, which is located on the lower side of the moving block.

[0015] The support rod is fixedly installed on the upper side of the movable block, and the upper end of the support rod passes through the top plate of the base and is installed on the lower side of the boss.

[0016] A limiting block is fixedly installed on the upper side of the base, and a support rod passes through the limiting block;

[0017] The spring is sleeved on the support rod, and the bottom end of the spring is connected to the moving block, and the upper end of the spring is connected to the bottom of the limiting block.

[0018] The insert sleeve is fitted and fixed to the upper end of the support rod, and the insert sleeve is movably inserted into the boss.

[0019] Through the above technical solution design, the rotary motor starts and drives the eccentric wheel to rotate. The rotation of the eccentric wheel drives the moving block. The movement of the moving block compresses the spring, causing the support rod to move until the sleeve is inserted into the boss, positioning the truncated cone and reinforcing the stability of the central shaft.

[0020] As a further improvement of this utility model, a steering seat is provided at the upper end of the central shaft, and a connecting buckle is hinged inside the steering seat via a hinge shaft.

[0021] Through the above technical solution design, the connecting buckle connects the steering seat to the workpiece.

[0023] The above technical solution design allows for easy disassembly of the movable cover, facilitating maintenance of the base's interior.

[0024] The working principle of this utility model is as follows: The drive motor is started, causing the rotating table and rotating component to rotate. When the rotating component rotates and the drive rod is placed in the slotted groove, it drives the rotating component to rotate, causing the central shaft to rotate. Each rotation of the rotating component achieves a 90° rotation. When the rotating table engages with the arc-shaped groove, the rotating component is in a fixed state. The rotating motor starts, driving the eccentric wheel to rotate. The rotation of the eccentric wheel drives the moving block, which in turn compresses the spring, causing the support rod to move until the insert sleeve is inserted into the boss, positioning the frustum and reinforcing the stability of the central shaft.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] 1. By driving the rotating table and rotating parts with a drive motor, the rotating parts are driven and positioned to achieve the purpose of rotation and fixing the angle;

[0027] 2. By adding an eccentric wheel and driving it, the spring is compressed. When the spring is compressed, the support rod moves upward to position the boss and strengthen the stability of the central shaft.

[0028] 3. The bottom of the base can be regularly maintained and inspected by removing the movable cover. Attached Figure Description
