Description

Technical Field

[0001] This utility model relates to the field of oiling equipment technology, specifically to a spring-rotating oiling device. Background Technology

[0002] Springs are fundamental components widely used in industrial fields, playing important roles such as cushioning, energy storage, and resetting in industries like machinery, automobiles, and electronics. During the production, storage, and use of springs, their surfaces are typically coated with lubricating oil or rust-preventive oil to reduce friction, prevent corrosion, extend their service life, and ensure their performance stability.

[0003] Currently, spring oiling mainly relies on two types of technical means: one is manual oiling, in which the operator holds a brush, oil can or spray gun, manually rotates the spring and moves the oiling tool along its axis, and manually controls the oiling trajectory and oil volume; the other is semi-automatic oiling equipment, which usually uses a simple bracket to support and position the spring, and oiling is achieved by manually rotating the spring or manually adjusting the position of the oiling nozzle. Existing technologies have significant drawbacks: First, manual and semi-automatic oiling relies on manual operation, resulting in low oiling efficiency, difficulty in meeting the needs of mass production, and high labor intensity, with operator fatigue easily leading to poor oiling consistency. Second, positioning stability is insufficient; traditional supports or V-grooves have limited fixing effect on the springs, causing them to wobble or shift during rotation or oiling, leading to uneven oil film thickness, and even problems such as missed coating or oil accumulation, affecting spring performance. Third, the oiling trajectory control precision is low; manual movement of the oiling nozzle cannot guarantee synchronization with the spring's rotation. Therefore, there is an urgent need for a device that can achieve stable spring positioning, automatic rotation, and precise axial oiling to solve the problems of low efficiency, poor oiling quality, and cumbersome operation in existing technologies. Utility Model Content

[0004] Purpose of the utility model: In order to overcome the above shortcomings, the purpose of this utility model is to provide a spring rotary oiling device. By setting a positioning device to form a semi-enclosed cavity to stably position the spring, the rotating mechanism clamps and drives the spring to rotate automatically, and the moving oiling mechanism moves precisely along the spring axis to apply oil, so as to improve the oiling efficiency, ensure the consistency and uniformity of oiling, and solve the problems of low efficiency caused by manual operation, uneven oil film caused by insufficient positioning stability, and low accuracy of oiling trajectory control in the prior art.

[0005] Technical Solution: This utility model provides a spring rotary oiling device including a base plate, and a positioning device, a rotating mechanism, and a moving oiling mechanism mounted on the base plate. The positioning device supports the spring and forms a semi-enclosed cavity to position the spring, ensuring that the spring is fixed in position during the oiling process and does not shift or shake. The rotating mechanism clamps and drives the spring located in the semi-enclosed cavity to rotate. By clamping the spring with the rotating mechanism and driving it to rotate at a uniform speed, a basic condition is provided for subsequent uniform oiling. The moving oiling mechanism moves along the axial direction of the spring during its rotation to apply oil, achieving full-length oiling coverage of the spring and avoiding localized missed areas.

[0006] Furthermore, in this application, a spring-rotating oiling device is provided, wherein the positioning device includes several supporting bases, a pair of bearing seats, and an optical shaft passing through the pair of bearing seats; a set of connecting blocks is sleeved on the optical shaft, the connecting blocks are bolted to an upper groove block fixing sheet metal, the upper groove block fixing sheet metal is bolted to an upper groove block, and the upper groove block has an upper horizontal groove; a lower groove block sheet metal bracket is installed on the supporting base, the lower groove block sheet metal bracket has a lower groove block, the lower groove block has a lower horizontal groove, and the spring is placed in the lower horizontal groove; a rotary cylinder is connected to the end of the optical shaft, the rotary cylinder is installed on the base plate, and is used to drive the optical shaft to rotate, thereby causing the upper groove block and the lower groove block to close or open; when the upper groove block and the lower groove block are closed, the upper horizontal groove and the lower horizontal groove cooperate to form the semi-closed cavity; the rotating mechanism clamps and drives the spring located in the semi-closed cavity to rotate, while the moving oiling mechanism extends into the semi-closed cavity to perform moving oiling. The optical shaft is driven to rotate by a rotary cylinder, which drives the connecting block, the upper groove block fixing sheet metal, and the upper groove block on the optical shaft to rotate synchronously, realizing the automatic closing and opening of the upper and lower groove blocks. After the upper and lower groove blocks are closed, the semi-enclosed cavity formed by the upper and lower horizontal grooves can not only stably accommodate the spring, but also reserve space for the rotating mechanism to hold the spring and the moving oiling mechanism to extend into the oiling, realizing the spatial coordination of the three major actions of positioning, rotation, and oiling, and avoiding the cavity structure from hindering the operation of other mechanisms.

[0007] Furthermore, in this application, a spring-rotating oiling device is provided, wherein the rotating mechanism includes a fixed block, a cylinder mounting base, a cylinder, a cylinder connecting block, a rotating shaft, a bushing, a gripper, a second bearing seat, a driven pulley, a motor, a motor mounting base, and a driving pulley; the fixed block is mounted on a base plate, the cylinder mounting base is mounted on the fixed block, the cylinder is mounted on the cylinder mounting base, and connected to the rotating shaft via the cylinder connecting block; the rotating shaft passes through the bushing and is connected to the gripper, the second bearing seat is mounted on the fixed block, the bushing is disposed within the second bearing seat, and the driven pulley... The wheel is fixed to the bushing; the spring is sleeved on the gripper, and the end of the rotating shaft is inverted conical; when the cylinder extends, the end of the rotating shaft extends out of the gripper, causing the gripper to retract, facilitating the loading and unloading of the spring; when the cylinder retracts, the inverted conical end of the rotating shaft opens the gripper, causing the gripper to tighten the spring; the driving pulley is mounted on the rotating shaft of the motor, and drives the driven pulley to rotate through belt drive, thereby driving the spring tightened on the gripper to rotate; at this time, the moving oiling mechanism performs an oiling operation on the rotating spring; wherein, the motor is mounted on the fixed block through a motor mounting base. By utilizing the extension and retraction of the cylinder and the inverted conical end design of the rotating shaft, the automatic tension control of the gripper on the spring is achieved: when the cylinder extends, the end of the rotating shaft extends outward, and the gripper naturally retracts due to the loss of support from the inverted conical structure, allowing for quick loading and unloading of the spring; when the cylinder retracts, the inverted conical end retracts simultaneously and presses against the inner wall of the gripper, forcing the gripper to open outward, thereby tightly gripping the inner wall of the spring. There is no need for manual adjustment of the gripper tension, thus completing the automatic positioning and clamping of the spring.

[0008] Furthermore, this application discloses a spring rotary oiling device, wherein the movable oiling mechanism includes a raised base, a linear module, a screw valve fixing seat, and a screw valve. The raised base is mounted on a base plate, the linear module is mounted on the raised base, the screw valve fixing seat is mounted on the slider of the linear module, and the screw valve is fixed on the screw valve fixing seat. The linear module drives the screw valve to move along the spring axis, and the output end of the screw valve extends into a semi-enclosed cavity. Oil is discharged from the screw valve, and with the assistance of air blowing, the oil is evenly applied to the spring in the form of atomized spray. The linear module is stably mounted on the base plate by the raised base, and its slider is rigidly connected to the screw valve fixing seat, which can drive the screw valve to perform uniform and high-precision reciprocating movement along the spring axis. This function allows for preset travel distances based on the actual length of the spring, ensuring that the output end of the screw valve fully covers the axial range of the spring. This avoids end-coating leaks due to insufficient movement. The travel speed can be adjusted in conjunction with the rotation speed of the rotating mechanism to adapt to different oiling process requirements. As the oiling actuator, the screw valve's output end precisely extends into the semi-enclosed cavity formed by the positioning device, employing a combined "oil output + air blowing" working mode: the screw valve precisely controls the oil output, and high-pressure air blows disperse the oil into tiny oil mist particles, which are then applied to the rotating spring surface in an atomized spray form. Compared to traditional spraying or brushing, this function achieves large-area, uniform contact between the oil and the spring surface, with stronger oil mist adhesion, penetrating even into the gaps between the spring particles.

[0009] Furthermore, in a spring-rotating oiling device of this application, the protective cover is mounted on a fixed block, and the cylinder fixing seat, cylinder, cylinder connecting block, rotating shaft, bushing, gripper, second bearing seat, driven pulley, motor, motor fixing seat and driving pulley cover are disposed inside the protective cover.

[0010] Furthermore, in one spring rotary oiling device of this application, the base plate is provided with handles at both ends along the axial direction of the linear module, and the handles facilitate the handling of the spring rotary oiling device.

[0011] As can be seen from the above technical solution, this utility model has the following beneficial effects: 1. The spring rotary oiling device of this utility model, by setting up a semi-enclosed positioning cavity driven by a rotary cylinder to open and close the upper and lower slot blocks, combined with a pneumatic gripper and belt-driven rotary mechanism, and an atomizing oiling unit driven by a linear module to move axially, realizes automatic clamping, stable rotation and precise axial oiling of springs, effectively solves the problems of low efficiency of manual operation, uneven oiling caused by unstable positioning and poor trajectory control accuracy, and significantly improves oiling efficiency and quality consistency.

Detailed Implementation

[0014] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0015] Example 1 This embodiment relates to a spring rotary oiling device. Its core purpose is to achieve stable positioning, uniform rotation, and precise axial oiling of the spring through an automated structure, thereby improving oiling efficiency and consistency. The device is constructed based on a base plate 1 and includes three main modules: a positioning device 2, a rotating mechanism 3, and a moving oiling mechanism 4. Handles 11 are provided at both ends of the base plate 1 for easy handling and installation.

[0016] like Figure 1 As shown, the device has a compact overall layout, with all components working together. The following is a detailed description of each module.

[0017] The positioning device 2 is used to form a semi-enclosed cavity to fix the spring. It includes several support bases 21 on the base plate 1, a pair of bearing seats 22, and an optical shaft 23 passing through the bearing seats 22. A set of connecting blocks 24 are sleeved on the optical shaft 23. The connecting blocks 24 are bolted to the upper groove block fixing sheet metal 25, and the upper groove block fixing sheet metal 25 is then fixed to the upper groove block 26. The upper groove block 26 has an upper horizontal groove 261. A lower groove block sheet metal bracket 27 is installed on the support base 21. The bracket has a lower groove block 28. The surface of the lower groove block 28 has a lower horizontal groove 281. The spring is initially placed in the lower horizontal groove 281. The end of the optical shaft 23 is connected to a rotary cylinder 29. The rotary cylinder 29 drives the optical shaft 23 to rotate, causing the upper groove block 26 and the lower groove block 28 to close or open. When closed, the upper horizontal groove 261 and the lower horizontal groove 281 cooperate to form a semi-enclosed cavity, effectively limiting the spring displacement.

[0018] Figure 2 The structure after the upper horizontal groove is unfolded is shown, and the upper and lower groove blocks are separated. Figure 3 for Figure 2 The enlarged area A clearly shows the docking details of the upper horizontal groove 261 and the lower horizontal groove 281.

[0019] The rotating mechanism 3 is responsible for clamping and driving the spring to rotate. It includes a fixed block 301, a cylinder mounting base 302, a cylinder 303, a cylinder connecting block 304, a rotating shaft 305, a bushing 306, a gripper 307, a second bearing seat 308, a driven pulley 309, a motor 310, a motor mounting base 311, and a driving pulley 312. The fixed block 301 is mounted on the base plate 1. The cylinder mounting base 302 fixes the cylinder 303, and the cylinder 303 is connected to the rotating shaft 305 via the cylinder connecting block 304. The rotating shaft 305 passes through the bushing 306 and connects to the gripper 307. The bushing 306 is located inside the second bearing seat 308, and the driven pulley 309 is fixed to the bushing 306. The end of the rotating shaft 305 has an inverted conical design: when the cylinder 303 extends, the end of the rotating shaft 305 extends the gripper 307, causing the gripper 307 to retract, facilitating the loading and unloading of the spring; when the cylinder 303 retracts, the inverted conical end expands the gripper 307, pressing it tightly against the inner wall of the spring. The motor 310 drives the driven pulley 309 through the driving pulley 312 and belt drive, causing the spring to rotate. The protective cover 313 covers the above components to ensure safety.

[0020] Figure 4 This is a schematic diagram of the structure after the spring has been removed, highlighting the internal layout of the rotating mechanism 3. Figure 5 for Figure 4 The middle B area is enlarged to highlight the inverted conical mating mechanism between the gripper 307 and the rotating shaft 305.

[0021] The movable oiling mechanism 4 achieves precise axial oiling. It includes a raised base 40, a linear module 41, a screw valve mounting base 42, and a screw valve 43. The raised base 40 is mounted on the base plate 1, the linear module 41 is fixed to the raised base 40, the screw valve mounting base 42 connects to the slider of the linear module 41, and the screw valve 43 is mounted on the mounting base 42. The linear module 41 drives the screw valve 43 to move uniformly along the spring axis. The output end of the screw valve 43 extends into the semi-enclosed cavity, and through a combination of oil output and air blowing, the oil is atomized and evenly sprayed onto the surface of the rotating spring.

[0022] Workflow Clamping stage: The rotary cylinder 29 drives the optical shaft 23 to rotate, which in turn opens the upper slot block 26. The operator places the spring in the lower horizontal slot 281 of the lower slot block 28 and puts it into the gripper 307.

[0023] Clamping and Rotation: The cylinder 303 of the rotating mechanism 3 retracts, and the inverted conical end of the rotating shaft 305 opens the clamping jaws 307, tightening the positioning spring. Then, the rotary cylinder 29 closes the upper slot block 26, forming a semi-closed cavity. The motor 310 starts and drives the spring to rotate at a constant speed via belt drive.

[0024] Oiling operation: The linear module 41 of the moving oiling mechanism 4 drives the screw valve 43 to move along the spring axis, while the screw valve 43 sprays oil in an atomized form to ensure that the oil film covers the entire area and is uniform.

[0025] Reset preparation: After the oiling is completed, cylinder 303 extends to release the spring, and rotary cylinder 29 opens the upper slot block 26 to remove the spring.

[0026] The above embodiments are exemplary and are intended to illustrate the technical concept and features of this utility model, so that those skilled in the art can understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model.
