Description
Technical Field
[0001] The utility model relates to the technical field of reciprocating motion components, and in particular discloses an improved rolling ball module. Background Art
[0002] During the use of product equipment, sometimes two components need to frequently reciprocate relative to each other. For example, during the use of a vibrating bed, the power system needs to drive the movable bed frame to frequently move back and forth relative to the fixed bed frame.
[0003] For example, a modular rolling guide rail unit announced in the prior application CN213298602U includes a fixed seat, a movable seat movably arranged relative to the fixed seat, and a roller member rollingly arranged between the fixed seat and the movable seat; the fixed seat has a first groove body, the movable seat has a second groove body for matching the first groove body, the roller member is accommodated in the groove body, and the two ends of the roller member are respectively accommodated in the first groove body and the second groove body.
[0004] Although this rolling guide rail mechanism can reduce the friction between the fixed seat and the movable seat and delay the wear between the fixed seat and the movable seat, during its actual use, the inventor found that the fixed seat and the movable seat adopt a single groove structure. When the movable seat moves horizontally forward and backward, the stability of the movable seat in the left and right horizontal directions is difficult to control. In other words, the movable seat is prone to shaking during displacement, which limits its reliability in use.
[0005] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content
[0006] In order to overcome the shortcomings and deficiencies in the prior art, the utility model aims to provide a slide rail device with low resistance and stable and reliable operation.
[0007] To achieve the above-mentioned purpose, the utility model provides an improved rolling ball module, including a mounting seat, and a movable part movably arranged relative to the mounting seat; the mounting seat is provided with a channel penetrating the mounting seat and matching with the movable part, and the mounting seat is sleeved on the movable part via the channel; a slide groove is provided on the inner wall of the mounting seat or / and the movable part, and a rolling part matching with the slide groove is provided between the mounting seat and the movable part, and the movable part is arranged to roll with the mounting seat via the rolling part. The utility model solves the problem that it is difficult to control the stability of the horizontal direction of the movable part when the movable part moves horizontally forward and backward by sleeved on the mounting seat to limit the displacement of the movable part, so that the movable part maintains stability during the movement, thereby improving the stability of the rolling ball module; at the same time, it reduces the possibility of dust and impurities entering the slide groove, and maintains the cleanliness and stability of the slide groove.
[0008] Furthermore, the movable part is a cylindrical strip, and the slide groove is arranged along the length direction of the movable part and runs through both ends of the movable part. The cylindrical strip will produce a uniform pressure distribution on the contact surface with the rolling part, which helps to reduce local stress concentration and make the ball module more stable when bearing load; at the same time, the cylindrical shape may be easier to achieve self-centering during movement, and even when the axial and radial loads change, it can maintain relatively stable movement characteristics.
[0009] Furthermore, the movable member is a rectangular bar, and the slide groove is arranged along the length direction of the movable member and runs through both ends of the movable member. The rectangular bar has a flat surface, which can provide a stable contact surface when contacting the rolling member, helping to ensure that the rolling member rolls smoothly. At the same time, the rectangular bar is more likely to resist torsional force and maintain the stability of the slider, especially under high speed or high load conditions.
[0010] Furthermore, the slide grooves are provided in multiple groups, and the multiple groups of slide grooves are distributed in a circular array around the central axis of the movable part. The multiple groups of slide grooves cooperate with the rolling parts to provide additional guidance, so that the movement of the movable part in the mounting seat is more stable and accurate. This design helps to reduce the swing and offset of the movable part during the movement, improve the movement accuracy of the movable part, and at the same time reduce the friction between the movable part and the mounting seat, making the movement smoother and more efficient. This helps to reduce energy loss and wear and extend the service life of the ball module.
[0011] Furthermore, the rolling elements in the chute are arranged in multiple groups, and the rolling elements are arranged along the length direction of the chute. Since the load is evenly distributed on the multiple rolling elements, the wear degree of a single rolling element can be reduced, and the service life of the rolling element and the mounting seat can be extended.
[0012] Furthermore, the chute is an arc-shaped groove, and the rolling element is a spherical ball. Increasing the contact area between the chute and the rolling element helps to reduce local stress concentration and ensure that the rolling element rolls smoothly.
[0013] Furthermore, the rolling element is made of silicone. Silicone has excellent wear resistance, can maintain a high surface quality in long-term use, reduce wear when in contact with the mounting seat and moving parts, thereby extending the service life of the mounting seat and moving parts; at the same time, silicone usually has good elasticity, which can reduce the noise of relative movement between the mounting seat and moving parts, and realize the "silent" use of the rolling ball module. At the same time, with the help of the elasticity of silicone, the vibration transmitted from the outside to the moving parts through the mounting seat is absorbed, ensuring that the moving parts can run smoothly.
[0014] Furthermore, the mounting seat is a rectangular bar, the mounting seat is fixedly connected to the external mounting frame via bolts, and the slide groove is arranged along the length direction of the mounting seat and passes through both ends of the mounting seat. The rectangular bar-shaped mounting seat increases the contact area between the mounting seat and the external mounting frame, and improves the stability of the mounting seat.
[0015] Furthermore, baffles are provided at both ends of the mounting seat, and the baffles are used to stop the rolling element in the slide groove. The baffles are provided with avoidance holes penetrating the baffles, and the movable element extends out of the baffles through the avoidance holes. With the arrangement of the baffles, all rolling elements are encapsulated in the slide groove, and the rolling element is prevented from falling from between the mounting seat and the movable element, which may cause the ball module to be used improperly, thereby extending the service life of the ball module.
[0016] Furthermore, both ends of the movable part are provided with connecting parts protruding from the movable part, and the movable part is fixedly connected to the external support frame via the connecting parts, so as to ensure that the movable part can run smoothly.
[0017] Beneficial effects of the utility model: The utility model sets the mounting seat on the movable part to limit the displacement of the movable part, so that the movable part maintains stability during movement, solves the problem that the stability of the left and right horizontal directions is difficult to control when the movable part moves horizontally forward and backward, and improves the stability of the ball rolling module; at the same time, it reduces the possibility of dust and impurities entering the slide groove, and maintains the cleanliness and stability of the slide groove; multiple groups of slide grooves and rolling parts can provide additional guidance, so that the movement of the movable part in the mounting seat is more stable and precise. This design helps to reduce the swing and deviation of the movable part during movement, improves the moving accuracy of the movable part, and can reduce the friction between the movable part and the mounting seat, making the movement smoother and more efficient. This helps to reduce energy loss and wear and extend the service life of the ball rolling module. BRIEF DESCRIPTION OF THE DRAWINGS

The utility model solves the problem that it is difficult to control the stability in the horizontal direction of the left and right when the movable part 2 moves horizontally forward and backward by sleeved on the mounting seat 1 to limit the displacement of the movable part 2, so that the movable part 2 maintains stability during the movement, thereby improving the stability of the rolling ball module; at the same time, it reduces the possibility of dust and impurities entering the slide groove 3, and maintains the cleanliness and stability of the slide groove 3.
[0028] The movable member 2 is a rectangular bar, and the chute 3 is arranged along the length direction of the movable member 2 and runs through both ends of the movable member 2.
