Description

Technical Field

[0001] This utility model relates to an auxiliary ball pressing device, and more particularly to a deep groove ball bearing filling rolling element mechanism. Background Technology

[0002] In the assembly of deep groove ball bearings, the ball pressing mechanism is mainly used to fill the rolling elements (such as steel balls) into the inner and outer ring grooves of the bearing. Typically, the inner and outer rings are laid flat on a horizontal worktable, and the operator manually places the steel balls one by one into the groove between the inner and outer rings. Due to gravity, the steel balls naturally fall to the lowest point, which is level with the bearing flange. In the subsequent assembly step, when the inner and outer rings are pressed together, the bearing flange inevitably comes into contact with the steel balls, causing impact damage to the surface of the steel balls. This damage can cause abnormal noise during bearing operation, the so-called "ball noise." To alleviate this problem, existing technology introduces an arc-shaped tooth structure, which is placed on the ball pressing platform to elevate the steel balls, aligning their center with the center of the ring groove. This avoids direct contact between the flange and the steel balls during assembly, ensuring a smooth initial assembly process.

[0003] However, this curved tooth design has significant shortcomings. First, the lack of a fixing device on the ball-pressing platform causes the curved tooth to easily shift position each time a new bearing is assembled, requiring repeated manual calibration by operators. This not only increases operation time but also reduces overall efficiency. Second, when assembling different types of bearings, the curved tooth cannot be integrally molded with the platform and must be customized or adjusted according to the specific model. This design lacks flexibility and is difficult to adapt to the needs of rapid model changeover and mass production, thus limiting the feasibility and economy of this device in large-scale industrial applications. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a deep groove ball bearing filling rolling element mechanism that solves the problems of arc-shaped tooth position misalignment and poor flexibility.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a deep groove ball bearing filling rolling element mechanism, comprising a base, the upper surface of which is used to place the ball bearing to be pressed, the ball bearing to be pressed comprising an outer ring and an inner ring, a raceway for filling rolling elements is formed between the outer ring and the inner ring, a fixed seat is slidably disposed on the base and an arc-shaped tooth is formed and fixed to the fixed seat in a detachable manner, the fixed seat is used to drive the arc-shaped tooth to slide on the base, and the fixed seat can be positioned on the base.

[0006] The beneficial effects of this utility model are as follows: The sliding fixed seat and the detachable curved tooth allow for flexible adjustment and reliable fixation of the curved tooth's position, avoiding positional shifts caused by the lack of a fixing device during ball pressing operations. This reduces the time spent on repeated manual calibration by operators, thereby improving operational efficiency and accuracy. Simultaneously, the detachable design allows for quick replacement of the curved tooth according to different bearing models, enhancing the adaptability and versatility of the device. This facilitates rapid model changeovers in mass production and reduces adjustment costs associated with model changes. As a preferred embodiment, the fixed seat is equipped with an axial adjustment groove, and the curved tooth is connected to the adjustment groove by bolts. This allows the operator to slide the curved tooth along the bearing axis to the desired position and then lock it, achieving precise axial positioning without the need for additional tools. As another preferred embodiment, a guide rail and locking mechanism are used between the fixed seat and the base. A slider moves on the guide rail and is fixed using a quick-clamping device, ensuring stable guidance of the fixed seat during sliding and preventing accidental displacement after positioning.

[0007] Furthermore, the base has a sliding groove at its center for the fixed seat to slide within it. The sliding groove has a T-shaped cross-section, and the fixed seat has a rectangular cross-section that matches the horizontal side of the sliding groove. The fixed seat has a fixing hole and a positioning hole. A fixing member passes through the fixing hole to engage with the arc-shaped tooth to form a detachable fixation. A positioning member passes through the positioning hole to engage with the bottom of the sliding groove to position the fixed seat.

[0008] The T-shaped sliding groove and the fixed seat provide stable guidance and support, preventing the fixed seat from shaking or tilting during sliding, ensuring the accuracy and repeatability of the arc-shaped tooth position, thereby reducing operational errors. The setting of the fixing hole and positioning hole allows the arc-shaped tooth to form a reliable connection with the fixed seat, and the fixed seat can be quickly positioned on the base, simplifying the installation and adjustment process and improving the overall stability and ease of use of the device. As a preferred method, the fixing hole is designed as an elongated slot, and the fastener uses a combination of bolts and nuts. The axial distance of the arc-shaped tooth is adjusted by sliding the bolt within the slot, achieving fine-tuning and locking, facilitating the installation requirements of different bearing models. As another preferred method, the positioning hole is aligned with the corresponding threaded hole at the bottom of the sliding groove, and a positioning pin or screw is inserted for fixation. Pressure is applied by rotating the screw to ensure the fixed seat is tightly against the bottom of the sliding groove, forming a strong mechanical connection and preventing loosening under vibration or load.

[0009] Furthermore, the arc-shaped tooth is connected to a connecting seat facing the fixing seat, and the connecting seat is provided with a connecting hole that can be spliced ​​with the fixing hole; the arc-shaped tooth is connected to one side of the connecting seat and its corresponding end face, and the cross-sectional width of the end face of the connecting seat corresponding to the arc-shaped tooth is greater than the cross-sectional width of the arc-shaped tooth.

[0010] The connecting seat enhances the connection strength between the curved tooth and the fixed seat. The splicing of the connecting and fixing holes enables detachable fixing, facilitating the replacement and maintenance of the curved tooth. Simultaneously, the wide end face provides a larger support area, effectively distributing the load generated during rolling element filling and preventing deformation or displacement of the curved tooth due to uneven stress. This structural design also improves the durability and reliability of the device, reducing the risk of failure due to loose connections. As a preferred option, the connecting seat is integrally cast or machined and connected to the curved tooth by welding or bolting, ensuring a gap-free connection. The wide end face is covered with an elastic gasket to buffer impact forces, further protecting the curved tooth and bearing assembly. Alternatively, a plug-in structure is used between the connecting seat and the fixed seat, connected by a quick-release pin, allowing operators to quickly disassemble and install the curved tooth without tools, improving maintenance efficiency and ease of operation.

[0011] Furthermore, the base is provided with a plurality of guard seats in the circumference of the sliding groove. The guard seats protrude from the end face of the base for placing the ball bearing to be pressed. The inner side of the plurality of guard seats forms a virtual circle with an inner diameter larger than the outer diameter of the ball bearing to be pressed.

[0012] The guard seat forms a protective enclosure, limiting the bearing's movement range through a virtual circle. This effectively prevents the bearing from accidentally detaching from the base during operation, reducing damage or production interruptions caused by bearing falls. Simultaneously, the inner surface design of the guard seat cushions the impact between the bearing and the base, reducing the risk of scratches or deformation on the bearing surface due to collisions, thus improving the safety and lifespan of the device. As a preferred option, the inner surface of the guard seat is covered with a polymer or rubber layer, which absorbs the impact energy during bearing movement through elastic deformation, reducing surface damage caused by hard contact. The polymer layer is also replaceable to adapt to different working environments. Alternatively, the guard seat employs an adjustable design, connected to the base via a screw mechanism. Operators can adjust the position of the guard seat and change the size of the virtual circle by rotating the screw, thereby accommodating various bearing outer diameters and ensuring both protective effectiveness and flexibility.

[0013] Furthermore, a positioning post is provided at the center of the lower surface of the base, and countersunk connecting holes are symmetrically provided on both radial sides of the positioning post.

[0014] The placement of the positioning pins and countersunk connecting holes facilitates quick and accurate connection between the base and the external platform. Initial alignment is achieved by the positioning pins engaging with corresponding holes on the platform, reducing adjustment time during installation. The countersunk connecting holes ensure that the connectors do not protrude from the surface, preventing interference with other operations or equipment and improving the overall structural compactness and safety. This design also enhances the stability of the base, preventing displacement under load and ensuring the accuracy and reliability of the rolling element filling process. As a preferred option, the positioning pins are designed with a stepped structure, using a transition fit with the platform holes. Precise positioning can be achieved with slight pressure, and the countersunk connecting holes are secured with hexagonal socket head cap bolts. The bolt heads are recessed into the holes without affecting the flatness of the base's upper surface. Alternatively, reinforcing ribs are placed around the positioning pins to increase the base's rigidity. The countersunk connecting holes use a threaded bushing embedding design, applying preload by rotating the bolts to create a secure connection between the base and the platform, suitable for high-frequency use environments.

Detailed Implementation

[0016] This utility model embodiment provides a deep groove ball bearing filling rolling element mechanism, such as... Figure 1-4 As shown: The mechanism includes a base 1, the upper surface 11 of which is used to place the ball bearing 4 to be pressed. The ball bearing 4 includes an outer ring 41 and an inner ring 42, and a raceway 43 for filling the rolling elements is formed between the outer ring 41 and the inner ring 42. A fixed seat 2 and an arc-shaped tooth 3 are slidably disposed on the base 1. The fixed seat 2 is used to drive the arc-shaped tooth 3 to slide on the base 1, and the fixed seat 2 can be positioned on the base 1. The arc-shaped tooth 3 is fixed to the fixed seat 2 in a detachable manner for easy replacement and to prevent displacement during use.

[0017] The base 1 has a sliding groove 12 at its center, within which the fixed seat 2 slides. The sliding groove 12 has a T-shaped cross-section, and the fixed seat 2 has a rectangular cross-section that matches the horizontal side of the sliding groove 12, providing a stable sliding and anti-detachment structure. The fixed seat 2 has a fixing hole 21 and a positioning hole 22. A fixing element such as a bolt passes through the fixing hole 21 to engage with the arc-shaped tooth 3 for detachable fixing. A positioning element such as a screw passes through the positioning hole 22 to engage with the bottom of the sliding groove 12 to position the fixed seat 2, thereby achieving precise position adjustment and locking of the fixed seat 2 within the sliding groove 12.

[0018] The curved tooth 3 is connected to a connecting seat 31 facing the fixed seat 2. The connecting seat 31 is provided with a connecting hole 311, which can be spliced ​​with the fixed hole 21 and detachably connected through a fastener. The curved tooth 3 is connected to one side of the connecting seat 31 and its corresponding end face. The cross-sectional width of the end face of the connecting seat 31 corresponding to the curved tooth 3 is larger than the cross-sectional width of the curved tooth 3 to enhance connection stability and prevent the curved tooth 3 from shifting position when carrying the rolling element.

[0019] The base 1 has several guard seats 13 arranged around the sliding groove 12. The guard seats 13 protrude from the upper surface 11 of the base 1. The inner side of the several guard seats 13 forms a virtual circle with an inner diameter larger than the outer diameter of the ball bearing 4 to be pressed, which is used to prevent the bearing from falling off during the movement of the bearing. At the same time, the surface of the guard seat 13 is designed to be smooth or made of a cushioning material to avoid damage to the bearing surface when it collides with the bearing surface.

[0020] A positioning post 141 is provided at the center of the lower surface 14 of the base 1. Countersunk connecting holes 142 are symmetrically provided on both radial sides of the positioning post 141 to form a firm connection between the base 1 and the external platform through bolts or other connecting parts, so as to ensure the stability of the entire mechanism during operation.

[0021] The working principle of this mechanism is as follows: First, the base 1 is fixed to the external platform via the positioning pin 141 and the countersunk connecting hole 142 to ensure the stability of the base 1. Then, the fixing seat 2 is inserted into the sliding groove 12 of the base 1, allowing the fixing seat 2 to slide within the sliding groove 12. Next, the arc-shaped tooth 3 is fixed to the fixing seat 2 via the connecting seat 31 and the fixing hole 21. By comparing the positions of the outer ring 41 and the inner ring 42 of the ball bearing 4 to be pressed, the axial position of the arc-shaped tooth 3 is adjusted to a suitable point. Afterward, the fixing seat 2 is positioned within the sliding groove 12 via the positioning hole 22 and the positioning element to prevent it from sliding. When filling the rolling elements, the arc-shaped tooth 3 guides the rolling elements into the raceway 43, making the entire process efficient and reliable.

[0022] The above embodiments are merely one preferred embodiment of the present utility model. Ordinary changes and substitutions made by those skilled in the art within the scope of the present utility model's technical solution are all included within the protection scope of the present utility model.
