Description

Technical Field

[0001] This utility model relates to the field of ball bushing technology, and in particular to a ball limiting structure for a ball bushing. Background Technology

[0002] Ball bushings, as key components in mechanical transmission systems, are widely used in various automated equipment, precision machine tools, aerospace machinery, and industrial robots. Their main function is to provide low-friction, high-precision support and guidance between relatively moving parts, ensuring smooth and accurate operation of the equipment.

[0003] In traditional ball bushing designs, the ball limiting structure typically takes a conventional form. A common approach is to use simple annular grooves or bosses inside the bushing to restrict the axial and radial displacement of the balls. However, with the ever-increasing performance requirements of modern industry, this traditional limiting structure has revealed numerous drawbacks. Under high-speed operating conditions, the balls are prone to collisions and friction, leading to heat accumulation. This not only reduces transmission efficiency but also accelerates wear on the balls and bushing, shortening the equipment's lifespan. When equipment faces complex and variable load conditions, traditional limiting structures struggle to effectively constrain the balls, easily resulting in balls slipping off the track or jamming, severely impacting the stability and reliability of the equipment's operation.

[0004] Traditional limit structures also present inconveniences in terms of maintenance. Once an internal fault occurs, the repair is difficult and often requires disassembly or even replacement of the entire bushing, resulting in long downtime and high maintenance costs. Therefore, a ball limit structure for ball bushings is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a ball limiting structure for a ball bushing, which aims to improve the problem of poor fixing effect in some existing devices.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] As a further description of the above technical solution:

[0009] The rotating fixing mechanism includes a connecting support ring, and a rotating fixing ring is rotatably connected inside the connecting support ring. The connecting support ring has a groove inside.

[0010] As a further description of the above technical solution:

[0011] The telescopic connecting rod 2 is rotatably connected to a connecting rotating column, the connecting rotating column is rotatably connected to a telescopic connecting rod 3, and the telescopic connecting rod 2 is rotatably connected to a connecting rotating ring 1.

[0012] As a further description of the above technical solution:

[0013] The telescopic connecting rod 2 is externally rotatably connected to two connecting rotating rings 3, and the connecting rotating rings 3 are internally rotatably connected to a connecting rotating ring 4;

[0014] As a further description of the above technical solution:

[0015] The external rotatable connection of the first connecting rotating ring is a fixed support block, and the external fixed connection of the fixed support block is a telescopic connecting rod.

[0016] As a further description of the above technical solution:

[0017] The output end of the telescopic cylinder is fixedly connected to a telescopic connecting rod, and the outside of the connecting rotating column is fixedly connected to a fixed arc plate.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, when the telescopic cylinder is activated, it drives the telescopic connecting rod one to move, which in turn pushes the fixed support block to move. The movement of the fixed support block causes the connecting rotating ring two to rotate synchronously with the connecting rotating ring one, driving the telescopic connecting rod three and the telescopic connecting rod two to move together with the fixed support block. During this process, the connecting rotating ring three and the connecting rotating ring four provide stable support for the telescopic connecting rod three and the telescopic connecting rod two. Through the coordinated operation of each component, the fixed arc plate is squeezed to achieve the purpose of fixing the ball. The structure can limit the displacement of the ball. Compared with the traditional limiting method, it effectively reduces the collision and friction of the ball during movement, significantly improves the stability and reliability of the ball bushing, and extends its service life.

[0024] 2. In this utility model, when the rotating handle starts to rotate, it will drive the rotating fixing ring connected to it to rotate together. The rotating fixing ring rotates smoothly inside the connecting support ring. As the rotation continues, the relative positions between the components are gradually fixed, thereby achieving the effect of fixing the system structure. Attached Figure Description

The externally rotatably connected telescopic connecting rod 206 is the rotating column 208, connecting the telescopic connecting rod 206 and the telescopic connecting rod 207, allowing them to rotate relative to each other. This ensures that under the push of the telescopic cylinder 201, the two connecting rods can change their included angle, achieving the pressing action on the fixed arc plate 2011. The movable column 208 is externally rotatably connected to a telescopic connecting rod three 207. The telescopic connecting rod two 206 is externally rotatably connected to a connecting rotating ring one 204, which is rotatably connected to the fixed support block 203. When the telescopic cylinder 201 pushes the telescopic connecting rod one 202, the motion is transmitted to the connecting rotating ring two 205. The telescopic connecting rod two 206 is externally rotatably connected to two connecting rotating rings three 209. The connecting rotating rings three 209 are internally rotatably connected to a connecting rotating ring four 2010, which is connected to the telescopic connecting rod two 206 and the connecting rotating column 208 respectively. A rotating connection provides stable support for the movement of telescopic connecting rod 206 and telescopic connecting rod 207. A fixed support block 203 is externally rotatably connected to the rotating ring 204, and a telescopic connecting rod 202 is externally fixedly connected.

[0033] Reference Figures 1 to 3The rotating fixing mechanism 3 includes a connecting support ring 301 with an internal groove for accommodating a rotating fixing ring 302, providing it with rotation space.

When the rotating handle 303 starts to rotate, it drives the rotating fixed ring 302 to rotate, which in turn drives the rotating fixed ring 302 to rotate inside the connecting support ring 301, thereby achieving the fixing effect.
