Description

Technical Field

[0001] This utility model relates to the field of universal joint technology, and in particular to an automatic synchronous installation device for universal joint oil nozzles. Background Technology

[0002] As a key component in automotive drive systems, universal joints require grease to be injected into their internal bearings or lubrication chambers via grease fittings to ensure transmission efficiency and service life. The installation accuracy of the grease fittings directly affects the ease of subsequent maintenance and the long-term reliability of the universal joint.

[0003] Chinese patent CN218170224U discloses a positioning device for a universal joint grease nipple, including a base, a column rotatably connected to the top center of the base, an adjusting seat movably connected to the top of the column, a positioning mechanism on the front of the adjusting seat, a tilting mechanism on the top left side of the column, and a rotating mechanism in the middle of the top of the base. This device can fix the universal joint above the adjusting seat via the positioning mechanism and tilt the adjusting seat via the tilting mechanism, facilitating the installation of grease nipples located at the top of the universal joint as well as those at the side angle, thus broadening its applicability.

[0004] However, this technical solution requires manual assistance for loading and unloading, cannot achieve automatic synchronous installation of multiple oil nozzles, lacks intelligent design, resulting in a long production time and low production efficiency for installing universal joint oil nozzles, and cannot achieve intelligent linkage with other equipment on the production line, making the technology relatively backward. Utility Model Content

[0005] To address the problem that the above solutions cannot achieve automatic synchronous installation and intelligent manufacturing of multiple oil nozzles, this utility model provides an automatic synchronous installation device for universal joint oil nozzles. It uses a horizontal operating platform as the supporting base and a ring conveyor belt as the conveying carrier. Equally spaced cross protrusions on the conveyor belt form a clearance fit with the cross-shaped groove at the bottom of the universal joint. Limiting components fix the universal joint from both sides, and a pushing and tightening device installs the oil nozzles, achieving automatic synchronous installation of multiple universal joint oil nozzles while ensuring the stability of the conveying process.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An automatic synchronous installation device for universal joint oil nozzles includes: The control panel is a horizontal rectangular load-bearing structure. The system includes: a conveyor belt (a ring-shaped conveyor structure with two drive rollers mounted on the center of the operating platform), extending from both ends of the conveying direction, with symmetrical support members below the extended sections, the tops of which are flush with the bottom of the conveyor belt; limiting components (diagonally symmetrically distributed on both sides of the conveyor belt's width direction, with their installation height flush with the center of the universal joint); a push-aligning device (mounted on the left and right sides of the conveyor belt's width direction between the two limiting components, with its overall installation height flush with the top of the universal joint's grease nipple); and a tightening device (mounted on a support beam above the corresponding universal joint, including a rotating component and a driving component, with a clamp at the end of the rotating component and the driving component mounted above it, with the axis of the rotating component coinciding with the conveyor belt's center line).

[0007] As an improvement, the upper surface of the conveyor belt is provided with cross protrusions at equal intervals along the conveying direction. The cross protrusions are integrally formed, and the center of the cross protrusions coincides with the center line of the conveyor belt.

[0008] As an improvement, the universal joint is a cross universal joint with a cross-shaped groove at the center of its bottom.

[0009] As an improvement, the cross arm size of the cross-shaped groove matches the cross arm size of the cross protrusion on the conveyor belt, and the cross protrusion and the cross-shaped groove are in clearance fit, specifically, the dimensions of each dimension of the cross arm of the cross protrusion are smaller than the corresponding dimensions of the cross arm of the groove.

[0010] As an improvement, the limiting component includes four identical first cylinders. The first cylinders are fixed to the workbench surface by a bracket. The cylinder barrel of the first cylinder is provided with a first piston rod, and a limiting block is provided at its end.

[0011] As an improvement, the limiting block has a semi-circular structure, and the radius of its arc surface is adapted to the radius of the recess on the side of the universal joint; when the first piston rod extends, the arc surface of the limiting block is in close contact with the recess on the side of the universal joint.

[0012] As an improvement, the push-aligning device includes two identical second cylinders. The second cylinders are fixed to the operating table surface by a bracket. The axis of the second cylinder is set along the width direction of the conveyor belt. A second piston rod is provided in the cylinder barrel, and a push-aligning block is provided at the end. When the second piston rod extends, the inner end face of the push-aligning block abuts against the side of the universal joint oil nozzle, pushing the offset oil nozzle to the placement position corresponding to the end of the clamp.

[0013] As an improvement, the push-up block is a cuboid structure made of flexible material.

[0014] As an improvement, the end of the clamp is a tapered mating structure with a gap in the center set along the conveyor belt conveying direction, the size of which matches the bottom diameter of the universal joint oil nozzle.

[0015] The beneficial effects of this utility model are as follows: (1) This utility model uses a horizontal operating table as the bearing base, an annular conveyor belt as the conveying carrier, a cross protrusion on the conveyor belt for universal joint positioning, a limiting component for fixing the universal joint, and a push-aligning device and a tightening device for installing the oil nozzle, thereby realizing the automatic synchronous installation of multiple universal joint oil nozzles and greatly improving the working efficiency of universal joint oil nozzle installation.

[0016] (2) This utility model realizes the continuous conveying of the universal joint through the ring conveyor belt, and sets a cross protrusion on the conveyor belt to form a gap fit with the cross groove at the bottom of the universal joint to initially position the universal joint and ensure the stability of the universal joint during the conveying process.

[0017] (3) This utility model limits the universal joint that is delivered by a semi-circular limiting block. By precisely fitting the arc surface with the concave part of the side of the universal joint, it achieves multi-directional limiting from the radial direction, avoiding the universal joint from rotating or displacing when installing the oil nozzle, and ensuring positioning accuracy.

[0018] (4) This utility model uses a flexible material push block to calibrate the position of the oil nozzle from the width direction, ensuring that the oil nozzle is accurately aligned with the clamp of the upper tightening device, solving the problem of oil nozzle offset caused by conveying or feeding. At the same time, the flexible push block avoids hard damage to the surface of the oil nozzle, and uses the elasticity of the material to buffer the push force to prevent over-calibration.

[0019] In summary, the entire process, from conveying and positioning to limiting and fixing, then to position calibration, and finally automatic tightening, utilizes the adaptability of the mechanical structure (cross-shaped anti-convex fit, arc-shaped limit, conical clamp) and the coordinated action of the drive device to achieve automatic synchronous installation of multiple universal joint oil nozzles. In particular, the symmetrical layout design provides a structural foundation for the synchronous installation of multiple oil nozzles. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0022] Example like Figure 1-2 As shown, this utility model provides an automatic synchronous installation device for universal joint nozzles, including: an operating table 1, a conveyor belt 2, a limiting component 3, a pushing device 4, and a tightening device 5. The operating table 1 is a horizontal rectangular load-bearing structure, providing a reliable support foundation. The conveyor belt 2 is a ring conveying structure, which is assembled in the middle of the operating table 1 through two transmission rollers on both sides. Both ends of the conveying direction extend out of the operating table 1, and support members 21 are symmetrically arranged below the extended sections. The top of the support members 21 is attached to the bottom of the conveyor belt 2, which can realize the uninterrupted conveying of universal joints 6. While automatically and synchronously installing multiple nozzles 7, it can also avoid material accumulation or supply interruption problems in the production process.

[0023] Preferably, the upper surface of the conveyor belt 2 is provided with cross-shaped protrusions 22 at equal intervals along the conveying direction. The cross-shaped protrusions 22 are integrally formed, and the center of the cross-shaped protrusions 22 coincides with the conveying center line of the conveyor belt 2. The universal joint 6 is a cross-shaped universal joint with a cross-shaped groove 61 at its bottom center. The dimensions of the cross arms of the cross-shaped groove 61 match the dimensions of the cross arms of the cross-shaped protrusions 22 on the conveyor belt 2. The cross-shaped protrusions 22 and the cross-shaped groove 61 are in a clearance fit, specifically, the dimensions of each dimension of the cross arms of the cross-shaped protrusions 22 are smaller than the corresponding dimensions of the cross arms of the cross-shaped groove 61. This allows for rapid initial positioning of the universal joint 6, preventing horizontal slippage during conveying, and avoiding assembly jamming due to dimensional errors, thus balancing positioning accuracy and smooth conveying. The limiting components 3 are diagonally symmetrically distributed on both sides of the width direction of the conveyor belt 2, and their installation height is flush with the middle of the universal joint 6. More specifically, the limiting components 3 include four identical first cylinders 31. The first cylinders 31 are fixed to the table surface of the operating table 1 by brackets. The cylinder barrel of the first cylinder 31 is provided with a first piston rod 32, and a limiting block 33 is provided at its end. The air pressure of the first cylinder 31 can be flexibly adjusted according to the specifications of the universal joint 6, which can ensure the clamping force of the limiting block 33 on the universal joint 6, avoid the universal joint 6 from shifting during processing, and prevent excessive force from damaging the workpiece. Compared with traditional mechanical limiting, the cylinder drive has a faster response speed and can complete the limiting action instantly when the universal joint 6 reaches the designated position, thereby improving production efficiency.

[0024] Preferably, the limiting block 33 has a semi-circular structure, and the radius of its arc surface is adapted to the radius of the recess on the side of the universal joint 6. When the first piston rod 32 extends, the arc surface of the limiting block 33 fits tightly with the recess on the side of the universal joint 6, which can increase the contact area between the limiting block 33 and the universal joint 6, improve the limiting stability, avoid sharp edges from scratching the surface of the universal joint 6, and protect the appearance and structural integrity of the workpiece. The straightening device 4 is respectively mounted on the left and right sides of the conveyor belt 2 in the width direction and located between the two side limiting components 3. The overall installation height is flush with the top of the oil nozzle 7. More specifically, the straightening device 4 includes two identical second cylinders 41. The second cylinders 41 are fixed to the table surface of the operating table 1 by a bracket. The axis of the second cylinder 41 is set along the width direction of the conveyor belt 2. The cylinder barrel is provided with a second piston rod 42 and a straightening block 43 is provided at the end. When the second piston rod 42 extends, the inner end face of the straightening block 43 abuts against the side of the oil nozzle 7. When the oil nozzle 7 is deviated, the second cylinder 41 drives the straightening block 43 to push it to the position corresponding to the clamp 53, ensuring the docking accuracy of the oil nozzle 7 with the subsequent tightening process. The cylinder driving force is stable and controllable and can adapt to the straightening requirements of oil nozzles 7 of different sizes.

[0025] Preferably, the push-aligning block 43 has a cuboid structure, which ensures that the nozzle 7 is subjected to uniform force during alignment, avoiding excessive local force that could lead to deformation. The use of flexible materials (such as rubber or silicone) buffers the impact force during the alignment process, effectively preventing scratches and bumps to the surface of the nozzle 7. The tightening device 5 is mounted on the support beam above the corresponding universal joint 6, and includes a rotating component 51 and a driving component 52. A clamp 53 is provided at the end of the rotating component 51, and the driving component 52 is mounted above the rotating component 51. The axis of the rotating component 51 coincides with the center line of the conveyor belt 2, ensuring that the center of the clamp 53 during rotation is completely aligned with the assembly center of the universal joint 6 and the nozzle 7, thus improving the assembly accuracy of the nozzle 7.

[0026] Preferably, the end of the clamp 53 has a tapered fit structure to quickly align with the oil nozzle 7. The center of the clamp 53 also has a gap set along the conveying direction of the conveyor belt 2, the size of which matches the bottom diameter of the oil nozzle 7 to prevent displacement during tightening.

[0027] Work process (1) The operator places the universal joint 6 on the conveyor belt 2 and achieves initial positioning by the cooperation of the cross-shaped groove 61 at the bottom of the universal joint 6 with the cross-shaped protrusion 22 on the surface of the conveyor belt 2. The conveyor belt 2 continuously transports the universal joint 6 to the processing area in a circular motion. (2) When the universal joint 6 reaches the working area of ​​the limiting assembly 3 along with the conveyor belt, the four diagonally distributed first cylinders 31 start synchronously, driving the first piston rod 32 to extend. The semi-circular limiting block 33 at the end fits the concave part of the side of the universal joint 6 with its arc surface, and after it fits tightly, it applies a uniform clamping force to the universal joint 6 from both sides, and fixes it precisely on the center line of the conveyor belt 3 to ensure the coaxiality of subsequent assembly; (3) While the limit assembly 3 fixes the universal joint 6, the push-aligning device 4 starts to work. The two second cylinders 41 extend the second piston rods 42 along the width direction of the conveyor belt, driving the flexible push-aligning block 43 to move closer to the side of the oil nozzle 7. If the oil nozzle 7 deviates from the center due to placement deviation, the push-aligning block 43 will push it smoothly to the position corresponding to the clamp 53 of the tightening device 5; (4) After positioning and correction are completed, the drive component 52 of the tightening device 5 is activated, driving the rotating component 51 to rotate. The conical structure at the end of the clamp 53 guides the bottom of the oil nozzle 7 to quickly enter the center gap, and tightens the oil nozzle 7 onto the universal joint 6 by rotational force. Since the axis of the rotating component 51 coincides with the center line of the conveyor belt 2, the entire tightening process maintains coaxiality, avoiding tilting or misalignment of the oil nozzle; (5) After assembly, the cylinders and piston rods of the limiting component 3 and the pushing device 4 are reset synchronously, releasing the workpiece. The conveyor belt 2 continues to operate, transporting the finished product to the next process. At the same time, the new universal joint 6 enters the processing area with the conveyor belt 3, starting the next round of automated assembly cycle. The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
