Description

Technical Field

[0001] This utility model belongs to the field of positioning technology, specifically relating to an aluminum alloy cup positioning fixture. Background Technology

[0002] In the manufacturing process of aluminum alloy cups, precise positioning is crucial for ensuring processing quality. Traditional positioning fixtures for aluminum alloy cups mostly employ a single-directional positioning method, such as bottom support or side clamping. This single-directional positioning method has significant drawbacks: firstly, bottom support alone cannot effectively constrain the sides of the cup, making it prone to wobbling or shifting during processing, thus compromising processing accuracy; secondly, simple side clamping is difficult to precisely match the tilt angle of the side walls of conical aluminum alloy cups, resulting in low positioning efficiency and the risk of cup deformation due to uneven clamping force, affecting product quality. Utility Model Content

[0003] The purpose of this utility model is to provide an aluminum alloy cup body positioning fixture to address the above-mentioned problems and solve the problems existing in the prior art.

[0004] This utility model is achieved through the following technical solution: an aluminum alloy cup body positioning fixture, including a base, a turntable rotatably installed inside the base, a spiral guide rail installed on the turntable, three pairs of synchronous plates arranged in a circle slidably on the spiral guide rail, a top block installed on each synchronous plate, and an extrusion plate in an inclined state installed on the top block.

[0005] A lead screw is installed at the center of the turntable, and a vertically limiting slide plate is meshed on the lead screw. A top rod is installed on the slide plate, and a top plate is installed on the top of the top rod. The turntable drives the lead screw to rotate, causing the top rod and the top plate to move upward and squeeze the bottom of the conical aluminum alloy cup, causing it to move upward. The spiral guide rail on the turntable drives the extrusion plate to slide towards the center, which cooperates with the upward-moving conical aluminum alloy cup to position it.

[0006] Furthermore, a pair of slide rails are installed at the bottom of the base. The pair of slide rails are used to install on the adapted workbench. The base is provided with an installation groove. Bolt holes are provided inside the installation groove and correspond to the slide rails. The bolt holes are used for later installation of locking bolts for positioning.

[0007] Furthermore, a drive motor is installed inside the base, and the output end of the drive motor is connected to the rotation center of the turntable. A slider is slidably arranged on the spiral guide rail, and the slider is connected to the bottom of the synchronization plate.

[0008] Furthermore, a sliding groove is provided on the base, the synchronizing plate passes through the sliding groove, and the side wall of the synchronizing plate and the side wall of the sliding groove are slidably connected. A limit rod is installed on the sliding groove, and the limit rod is movably connected to the synchronizing plate.

[0009] Furthermore, a synchronous shaft is installed at the rotation center of the turntable, and the synchronous shaft moves through the base. A positioning plate for limiting the position is installed on the top of the synchronous shaft.

[0010] Furthermore, a positioning rod is vertically installed inside the slide plate. The bottom of the positioning rod is welded to the bottom of the base, and the height of the positioning rod is lower than the height of the lead screw shaft.

[0011] This invention utilizes a unique dual-drive structure. A turntable drives a lead screw shaft to push the top plate upwards, pressing against the bottom of the cup and causing the cup to move upwards. Simultaneously, a spiral guide rail causes the pressing plate to contract towards the center, with its inclined surface applying inward pressure against the side of the cup. This simultaneous bottom lifting and side clamping mechanism, employing a design that adapts the conical cup sidewall to the inclined surface of the pressing plate, allows for quick and precise fixing of the cup in a preset position. Compared to traditional single-direction positioning methods, this significantly improves positioning efficiency and accuracy, effectively reducing processing errors caused by positioning deviations and providing a stable and reliable foundation for subsequent processing steps.

[0018] The present invention will be further illustrated below with reference to specific examples and accompanying drawings.

[0019] like Figures 1-4As shown, this utility model describes an aluminum alloy cup positioning fixture, including a base 1, a turntable 12 rotatably mounted inside the base 1, a spiral guide rail 11 mounted on the turntable 12, and three pairs of circularly distributed synchronous plates 7 slidably arranged on the spiral guide rail 11. Each synchronous plate 7 is equipped with a top block 5, and an inclined extrusion plate 6 is mounted on the top block 5. Through this structural design, the three pairs of extrusion plates 6 can constrain the aluminum alloy cup from multiple directions simultaneously. Compared with the traditional single-sided or few-point positioning method, it can effectively prevent the cup from shifting or shaking during the positioning process, significantly improve positioning stability, and thus ensure high precision in subsequent processing.

[0020] A lead screw 15 is mounted at the center of rotation of the turntable 12. A vertically limiting slide plate 18 is meshed on the lead screw 15. A top rod 19 is mounted on the slide plate 18, and a top plate 20 is mounted on the top of the top rod 19. The turntable 12 drives the lead screw 15 to rotate, causing the top rod 19 and the top plate 20 to move upward and compress the bottom of the conical aluminum alloy cup, causing it to move upward. At the same time, the spiral guide rail 11 on the turntable 12 drives the extrusion plate 6 to slide towards the center, cooperating with the upward-moving conical aluminum alloy cup to position it. This dual-drive structure, which simultaneously lifts the bottom and clamps the side, greatly improves the positioning efficiency compared to the traditional single-direction positioning method. Operations that originally required steps can now be completed simultaneously, significantly shortening the positioning time of a single cup and improving production efficiency. At the same time, the precise force applied in both directions ensures that the cup can be stably and accurately fixed in the preset position, reducing the scrap rate caused by positioning errors.

[0021] like Figures 1 to 4 As shown in the specific embodiment, a pair of slide rails 2 are installed at the bottom of the base 1. The slide rails 2 are used to install on the adapted workbench, and the base 1 has a mounting groove 3. The mounting groove 3 has bolt holes 4 inside, and the bolt holes 4 correspond to the slide rails 2. The bolt holes 4 are used for later installation of locking bolts for positioning. This installation design allows the tooling to be quickly and easily installed on different workbench surfaces without a complicated debugging process. This not only reduces the installation difficulty but also reduces installation time and labor costs, and improves the deployment flexibility of the production line.

[0022] like Figures 1 to 4 As shown, a drive motor 13 is further installed inside the base 1. The output end of the drive motor 13 is connected to the rotation center of the turntable 12. A slider 10 is slidably mounted on the spiral guide rail 11, and the slider 10 is connected to the bottom of the synchronization plate 7. The drive motor 13 provides stable and strong power to ensure that the turntable 12 can operate continuously and stably, thereby ensuring the continuity and reliability of the entire positioning process and avoiding inaccurate positioning or jamming due to insufficient power.

[0023] like Figures 1 to 4As shown, a further feature is provided on the base 1: a sliding groove 8, through which the synchronization plate 7 passes, and the sidewall of the synchronization plate 7 is slidably connected to the sidewall of the sliding groove 8. A limiting rod 9 is installed on the sliding groove 8, and the limiting rod 9 is movably connected to the synchronization plate 7. The sliding groove 8 and the limiting rod 9 provide precise guidance and limitation for the sliding of the synchronization plate 7, effectively preventing the synchronization plate 7 from shifting or jamming during the sliding process, ensuring that the extrusion plate 6 can accurately slide towards the center and fit against the side of the cup body, further improving the positioning accuracy.

[0024] like Figures 1 to 4 As shown, a synchronous shaft 14 is further installed at the rotation center of the turntable 12, and the synchronous shaft 14 moves through the base 1. A positioning plate 16 for limiting the position is installed on the top of the synchronous shaft 14. The synchronous shaft 14 ensures the coaxiality and stability of the rotation of the turntable 12, reduces the shaking of the turntable 12 during rotation, and, together with the positioning plate 16, provides reliable support and positioning reference for the operation of the entire tooling, enhancing the overall stability of the tooling.

[0025] like Figures 1 to 4 As shown, a positioning rod 17 is vertically installed inside the slide plate 18. The bottom of the positioning rod 17 is welded to the bottom of the base 1, and the height of the positioning rod 17 is lower than the height of the lead screw shaft 15. The positioning rod 17 limits the vertical movement of the slide plate 18, so that the slide plate 18 can only move up and down along the lead screw shaft 15. This ensures that the top plate 20 can vertically press the bottom of the cup upwards, avoiding uneven force due to offset, thereby achieving stable and precise lifting of the cup body.

[0026] The implementation principle of the aluminum alloy cup positioning fixture is as follows:

[0027] When positioning the conical aluminum alloy cup body is required, the drive motor 13 is started, which drives the turntable 12 to rotate, thereby causing the lead screw shaft 15 at the center of the turntable 12 to rotate. Because the sliding plate 18, which is engaged with the lead screw shaft 15, is vertically limited by the positioning rod 17 (the positioning rod 17 vertically passes through the sliding plate 18 and is welded to the bottom of the base 1), the rotation of the lead screw shaft 15 causes the sliding plate 18 to move upward along the lead screw shaft 15. The top rod 19 and top plate 20 on the sliding plate 18 also rise accordingly. After the top plate 20 rises, it applies an upward compressive force to the bottom of the conical aluminum alloy cup body, causing the cup body to move upward.

[0028] Simultaneously, as the turntable 12 rotates, its spiral guide rail 11 operates accordingly. Since the slider 10 is connected to the bottom of the synchronization plate 7 and can slide on the spiral guide rail 11, the rotation of the spiral guide rail 11 drives the slider 10 to move along the guide rail trajectory, thereby causing the three pairs of synchronization plates 7 to contract towards the center along a circular trajectory. The top block 5 and the extrusion plate 6 on the synchronization plate 7 also move together. The extrusion plate 6 is in an inclined state. As it slides towards the center, its inclined surface gradually comes into contact with the side of the aluminum alloy cup body and applies inward extrusion force, reducing the inner diameter of the tooling's internal space.

[0029] As the cup moves upward, its conical sidewall gradually enters the reduced inner diameter space of the extrusion plate 6. Because the inclination angle of the extrusion plate 6 matches the conical sidewall of the cup, the sidewall is held and fixed by the extrusion plate 6 as the cup moves upward. Through the dual action of the upward extrusion of the top plate 20 and the inward contraction of the extrusion plate 6, forces are applied to the aluminum alloy cup from the bottom and the side simultaneously, achieving precise positioning of the conical aluminum alloy cup.

[0030] The above embodiments are merely preferred embodiments of the present utility model and are only used to explain the present utility model, not to limit the present utility model. Any changes, substitutions, combinations, simplifications, modifications, etc., made by those skilled in the art without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
