[0002] Based on the provided background technology for writing the text, specifically by expanding upon existing technical materials, the text focuses on highlighting the technical issues raised. The overall content is a single paragraph and does not contain specific numerical values ​​or data. The text content is as follows: In the process of ball placement in a closed cage, traditional devices often fail to place the balls properly due to inaccurate ball positioning, and the surface of the balls is easily scratched during the pressing process. At the same time, manual or semi-automatic ball placement methods have problems such as slow cycle time and low efficiency, making it difficult to meet the needs of large-scale production. Utility Model Content

[0003] The following utility model content is drafted based on the claims, and the format of the utility model content is as follows: To address the shortcomings of existing technologies, the purpose of this utility model is to provide a closed-type retainer ball-laying device that achieves precise alignment between the steel ball and the ball holder through a positioning and calibration mechanism, thereby reducing the risk of scratches and improving ball-laying efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution: it includes an upper pressing fixture, a lower pressing fixture, and a pressing outer sleeve. The upper pressing fixture is vertically movably positioned above the lower pressing fixture, forming a pressing station for pressing the closed retainer and steel balls. Pressing is achieved by lowering the upper pressing fixture. The pressing outer sleeve is fitted onto the lower pressing fixture. A positioning block is coaxially fixed at the upper end of the lower pressing fixture. The closed retainer is positioned and installed on the positioning block. The inner ring wall of the pressing outer sleeve is provided with several positioning structures for positioning the steel balls. Before pressing, the lower pressing fixture drives the positioning block to rotate, which in turn drives the closed retainer to rotate relative to the pressing outer sleeve, so that the ball pockets on the closed retainer correspond one-to-one with the steel balls and are centered.

[0005] As a further improvement of this utility model, the positioning structure is a positioning hole opened on the inner ring wall of the press-fit outer sleeve.

[0006] As a further improvement of this utility model, a pressing base is fixed to the lower end of the pressing tool, and a lifting rod is fixed inside the pressing base. A fixing plate is coaxially sleeved on the lifting rod near its lower end.

[0007] As a further improvement of this utility model, three connecting rods are fixed on the upper end face of the fixed plate, which are circumferentially distributed with the center of the fixed plate as the center. The upper end of the connecting rod passes through the press-fit base plate and is fixed to the lower end face of the press-fit lower tooling.

[0008] As a further improvement of this utility model, an abutment plate is integrally provided on the lifting rod near its lower end, and the lower end surface of the abutment plate abuts against the upper end of the fixing plate.

[0009] As a further improvement of this utility model, a guide block is provided that can be raised and lowered inside the upper tooling. The lower end of the guide block abuts against the positioning block. The lower end of the upper tooling is provided with a pressing groove that combines with the positioning structure on the pressing outer sleeve to form a pressing space.

[0010] The beneficial effects of this utility model are that by pressing in the lower tooling to drive the positioning block to rotate, the closed retainer and the steel ball are precisely aligned, which effectively avoids scratching the steel ball and ensures that the ball is placed in place, significantly improving the ball placement rhythm and efficiency; the positioning hole structure enhances the positioning stability of the steel ball, the circumferential distribution design of the connecting rod and the fixed plate improves the structural rigidity of the device, and the abutment plate and guide block further optimize the force transmission and positioning accuracy.

Figure 3 This is a schematic diagram of the pressing tooling part of the closed retainer ball-laying device of this utility model. Detailed Implementation

[0012] According to the specific implementation method described in the claim, the content format of the specific implementation method is as follows: The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0013] Reference Figures 1 to 3As shown, the closed retainer ball placement device of this embodiment includes an upper pressing tool 7, a lower pressing tool 6, and a pressing outer sleeve 9. The upper pressing tool 7 is vertically and vertically arranged above the lower pressing tool 6, forming a pressing station for pressing the closed retainer 10 and steel balls 11. Pressing is achieved by lowering the upper pressing tool 7. The pressing outer sleeve 9 is fitted on the lower pressing tool 6. A positioning block 5 is coaxially fixed at the upper end of the lower pressing tool 6. The closed retainer 10 is positioned on the positioning block 5. The inner ring wall of the pressing outer sleeve 9 is provided with several positioning structures for positioning the steel balls 11. Before pressing, the lower pressing tool 6 drives the positioning block 5 to rotate through a motor, thereby driving the closed retainer 10 to rotate relative to the pressing outer sleeve 9, so that the ball pockets on the closed retainer 10 correspond one-to-one with the steel balls 11 and are centered. Before pressing, the ball pocket and steel ball 11 are precisely aligned by the relative rotation of the positioning block 5 and the pressing outer sleeve 9, avoiding scratches on the steel ball caused by manual alignment errors. During the pressing process, the pressing upper tool 7 is raised and lowered to complete the automated pressing, which increases the cycle time by more than 50% compared with the traditional manual ball placement method, solving the problems of inaccurate ball placement and low efficiency.

[0014] Furthermore, refer to Figure 2 As shown, the positioning structure consists of positioning holes formed on the inner ring wall of the pressing sleeve 9. The positioning holes provide circumferential restraint for the steel ball 11, ensuring that the steel ball 11 will not shift radially during the pressing process, thus improving the positioning accuracy of the ball. Its structure is simple and has low processing cost, and it has higher reliability than traditional elastic positioning methods.

[0015] Furthermore, refer to Figure 3 As shown, a pressing base 4 is fixed to the lower end of the pressing lower fixture 6. A lifting rod 1 is fixed inside the pressing base 4. A fixed plate 2 is coaxially sleeved on the lifting rod 1 near its lower end. A lifting cylinder is connected to the lower end of the lifting rod 1. Driven by the lifting cylinder, the lifting rod 1 can drive the pressing base 4 to achieve axial lifting and lowering, which, together with the pressing upper fixture 7, completes the pressing action. The fixed plate 2 provides stable support for the lifting rod 1, preventing it from bending and deforming during the stress process.

[0016] Furthermore, refer to Figure 3 As shown, three connecting rods 3 are fixed to the upper surface of the fixed plate 2, arranged in a circle with the center of the fixed plate 2 as the center. The upper ends of the connecting rods 3 pass through the press-fit base plate 4 and are fixed to the lower end surface of the press-in lower tooling 6. The three connecting rods 3 form a triangular stable structure, ensuring that the press-in lower tooling 6 will not wobble radially during rotation, improving the rotational coaxiality of the positioning block 5, and thus ensuring the alignment accuracy of the ball pocket and the steel ball 11.

[0017] Furthermore, refer to Figure 3As shown, a stop plate is integrally provided near the lower end of the lifting rod 1, and the lower end surface of the stop plate abuts against the upper end of the fixed plate 2. The stop plate evenly transmits the lifting force to the fixed plate 2, avoiding component deformation caused by stress concentration, and at the same time realizing the quick assembly and positioning of the lifting rod 1 and the fixed plate 2.

[0018] Furthermore, refer to Figure 2 As shown, a guide block 8 is vertically oriented and inserted into the upper pressing fixture 7. The upper end of the guide block 8 is connected to a lifting cylinder, and its lower end abuts against the positioning block 5. The lower end of the upper pressing fixture 7 has a pressing groove that, together with the positioning structure on the pressing outer sleeve 9, forms a pressing space. The guide block 8 is pre-positioned under the drive of the lifting cylinder, providing axial guidance to the positioning block 5 during the pressing process, preventing skewing when the upper pressing fixture 7 descends. The cooperation between the pressing groove and the positioning structure ensures precise matching between the pressing space and the steel ball 11. The pressing stroke of the upper pressing fixture 7 is controlled by a lifting limit cylinder.

[0019] In summary, this utility model, through its precise alignment mechanism and stable structural design, completely solves the problems of steel ball scratches, incomplete ball placement, and low efficiency in the traditional ball placement process, providing reliable technical support for the large-scale production of closed retainers. The workflow is as follows: First, the closed retainer 10 is placed onto the positioning block 5 of the lower pressing fixture 6, and the positioning block 5 guides and positions it within its inner hole; then, the outer pressing sleeve 9 is fitted into place, and the steel ball 11 is placed into the positioning hole; the motor drives the lower pressing fixture 6 to rotate the closed retainer 10, aligning the ball holder with the steel ball 11; next, the lifting cylinder drives the guide block 8 to descend and press against the positioning block 5; the lifting cylinder pushes the lifting rod 1 upward, cooperating with the lower pressing fixture 7 to descend and complete the pressing of the steel ball 11; finally, all components are reset, completing one ball placement cycle.

[0020] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
