Description

Technical Field

[0001] This invention relates to the field of precision machinery technology, and in particular to an auxiliary oscillation mechanism for an oilstone frame. Background Technology

[0002] In precision machining, especially in grinding and polishing processes involving complex curved surfaces or high-precision surfaces, the oilstone holder, as a key actuator that directly contacts the workpiece, has a motion trajectory whose complexity and stability are crucial to the final machining quality. Traditional oilstone holder drive mechanisms often employ simple linear reciprocating oscillations or rotational motions, which are insufficient to meet the demands of complex, multi-dimensional composite oscillation trajectories. Such single-dimensional motion modes easily lead to uneven grinding and low efficiency, especially when processing workpieces with complex shapes, making it difficult to achieve ideal surface quality. Some mechanisms attempting to achieve composite motions are often structurally complex, requiring multiple power sources or complex transmission chains, resulting in bulky equipment, high costs, increased energy consumption, and difficulty in guaranteeing reliability, while motion accuracy and synchronization are also easily affected. Furthermore, existing mechanisms also face challenges in maintaining a stable and appropriate contact pressure between the oilstone holder and the workpiece while ensuring precise and controllable oscillation trajectories. Summary of the Invention

[0003] This invention relates to an auxiliary oscillation mechanism for an oilstone rack, which has a compact structure, high transmission efficiency, and precise and stable motion. It can significantly improve the grinding and polishing effect and working efficiency of the oilstone rack, while also having the advantages of high reliability and ease of implementation.

[0004] This invention provides an auxiliary oscillation mechanism for an oilstone rack, specifically comprising: a base; a base fixedly mounted on the upper end of the base, a carrier seat above the base, an oscillation transmission frame and a drive frame positioned between the base and the carrier seat, the oscillation transmission frame and the drive frame being vertically distributed; a composite oscillation frame positioned at each end of the oscillation transmission frame, the composite oscillation frame being equipped with a composite oscillation mechanism; the oscillation transmission frame being equipped with an oscillation transmission mechanism, the drive frame being equipped with a drive mechanism, the drive mechanism being used to drive the oscillation transmission mechanism, the oscillation transmission mechanism being used to link with the composite oscillation mechanism, the composite oscillation mechanism being used to drive the carrier seat to oscillate, and the carrier seat being used to clamp and mount the oilstone rack.

[0005] Optionally, a tension spring is fixedly connected to each end of the front and rear sidewalls of the base.

[0006] Optionally, follower legs are fixedly installed vertically downward at the four corners of the bottom of the carrier. A slot is opened vertically on one side of the follower leg. A pull pin is fixedly installed vertically on the lower outer wall of the follower leg. The pull pin is fixedly connected to the other end of the tension spring. Two bearing seats are fixedly installed on the bottom plane of the carrier at the positions corresponding to the location of the oscillation compound mechanism.

[0007] Optionally, the oscillation transmission mechanism includes a transmission shaft, a worm gear, a fork arm, and a turntable. The transmission shaft is rotatably mounted on the base via a support frame. A worm gear is fixedly provided in the middle of the transmission shaft, and turntables are fixedly provided at both ends of the transmission shaft. A "U"-shaped fork arm is rotatably mounted on the transmission shaft inside the turntable.

[0008] Optionally, the drive mechanism includes a drive motor, a drive shaft, and a worm gear. The drive shaft is longitudinally fixedly mounted on the upper middle part of the base via a support frame. The drive motor is fixedly mounted on the support frame at one end of the drive shaft. The drive motor is used to drive the drive shaft to rotate. A worm gear is provided in the middle of the drive shaft, and the worm gear meshes with a worm wheel.

[0009] Optionally, the composite oscillation mechanism includes an oscillating horizontal shaft, a cam, a vibrating arm, a connecting rod, a sleeve shaft, a support arm, a hanger, and a hanging shaft. The oscillating horizontal shaft is longitudinally rotatably mounted on the base via a support frame. Both ends of the oscillating horizontal shaft pass through the ends of the fork arms, and a cam is fixedly connected to the end of the oscillating horizontal shaft. One end of the cam is always slidably placed in the slot of the follower foot column. Two symmetrical vibrating arms are fixedly connected in the oscillating horizontal shaft. A connecting rod is fixedly connected between the ends of the vibrating arms. A sleeve shaft is slidably mounted on the connecting rod, and the end of the sleeve shaft is vertically slidably inserted into the position of the turntable near the edge.

[0010] Optionally, the two ends of the connecting rod are respectively rotatably sleeved with support arms, and the other end of the support arm is rotatably installed with a hanger. The two ends of the hanger are vertically provided with hanging shafts, and the hanging shafts are respectively slidably inserted into both sides of the shaft seat. The hanger slides in the shaft seat through the hanging shafts.

[0011] This invention provides an auxiliary oscillation mechanism for an oilstone rack, which has the following beneficial effects: First, this mechanism creatively utilizes a single drive motor as the power source, employing a highly efficient meshing transmission between a worm gear and a worm wheel to stably convert the longitudinal rotation of the drive shaft into the lateral rotation of the transmission shaft. This significantly simplifies the power transmission structure and improves transmission efficiency and reliability. Second, the core composite oscillation mechanism is ingeniously designed: the rotational motion of the turntables at both ends of the transmission shaft directly drives the oscillating horizontal axis to generate a basic oscillation through the fork arms; simultaneously, the eccentric motion of the turntables pushes and pulls the connecting rod through the sleeve shaft. This push-pull action not only further intensifies the oscillation amplitude of the oscillating horizontal axis through the vibrating arm but also drives the hanger to slide within the bearing seat through the support arms at both ends of the connecting rod. The oscillation of the oscillating horizontal axis drives the cam at its end to move within the slot of the carrier's follower foot, pushing the carrier to generate oscillation in the first dimension (e.g., the front-to-back direction); simultaneously, the sliding of the hanger causes the carrier to generate oscillation in the second dimension (e.g., the up-and-down direction) perpendicular to it. This ingenious design allows for the efficient and coordinated synthesis of composite oscillation motion of the carrier in two vertical directions using only a single drive motor. The motion trajectory is complex yet precisely controllable, greatly satisfying the requirements of high-quality grinding and polishing. Third, the tension spring positioned between the base and the carrier plays multiple crucial roles: providing elastic restoring force for smoother carrier movement; partially balancing the load and reducing the drive load; and most importantly, continuously applying tension to ensure the cam maintains reliable contact pressure with the slot, avoiding the risk of disengagement during movement and guaranteeing the accuracy and stability of the oscillation trajectory transmission. Fourth, the sliding fit design of the follower pin and its slot, and the shaft seat and its mounting shaft, provides precise guidance and constraint for the movement of the cam and the mounting element, further ensuring the accuracy and repeatability of the oscillation trajectory. Finally, the robust support frame composed of the base, the carrier, the oscillation transmission frame, and the drive structure ensures the accuracy of the relative positions of each component and the rigidity of the overall mechanism, providing a solid foundation for the stable realization of complex oscillating motion.

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please refer to Figures 1 to 8 : Example 1: This invention proposes an auxiliary oscillation mechanism for an oilstone frame, comprising: a base 1; a base 2 fixedly mounted on the upper end of the base 1, a carrier 3 above the base 2, an oscillation transmission frame 4 and a drive frame 5 between the base 2 and the carrier 3, the oscillation transmission frame 4 and the drive frame 5 being vertically distributed; a composite oscillation frame 6 is provided at both ends of the oscillation transmission frame 4, and a composite oscillation mechanism is provided on the composite oscillation frame 6; an oscillation transmission mechanism is provided on the oscillation transmission frame 4, and a drive mechanism is provided on the drive frame 5. The drive mechanism is used to drive the oscillation transmission mechanism, the oscillation transmission mechanism is used to link the composite oscillation mechanism, the composite oscillation mechanism is used to drive the carrier 3 to partially oscillate, and the carrier 3 is used to clamp and mount the oilstone frame.

[0018] Among them, a tension spring 21 is fixedly connected to each end of the front and rear side walls of the base 2.

[0019] Among them, the four corners of the bottom of the carrier 3 are respectively fixedly vertically downward with follower foot columns 31. A slot 311 is vertically opened on one side of the follower foot column 31. A pull pin 312 is vertically fixed on the lower outer wall of the follower foot column 31. The pull pin 312 is fixedly connected to the other end of the tension spring 21. Two bearing seats 32 are fixedly installed on the bottom plane of the carrier 3 at the positions corresponding to the location of the oscillation compound mechanism.

[0020] The oscillation transmission mechanism includes a transmission shaft 41, a worm gear 42, a fork arm 43, and a turntable 44. The transmission shaft 41 is rotatably mounted on the base 2 via a support frame. The worm gear 42 is fixedly installed in the middle of the transmission shaft 41. The turntables 44 are fixedly installed at both ends of the transmission shaft 41. A "U"-shaped fork arm 43 is rotatably mounted on the transmission shaft 41 inside the turntable 44.

[0021] The drive mechanism includes a drive motor 51, a drive shaft 52, and a worm gear 53. The drive shaft 52 is longitudinally fixedly installed in the middle of the upper end of the base 2 via a support frame. The drive motor 51 is fixedly installed on the support frame at one end of the drive shaft 52. The drive motor 51 is used to drive the drive shaft 52 to rotate. The worm gear 53 is provided in the middle of the drive shaft 52, and the worm gear 53 meshes with the worm wheel 42.

[0022] The composite oscillation mechanism includes an oscillating horizontal shaft 61, a cam 62, a vibrating arm 63, a connecting rod 64, a sleeve shaft 65, a support arm 66, a hanger 67, and a hanging shaft 671. The oscillating horizontal shaft 61 is longitudinally rotatably mounted on the base 2 via a support frame. Both ends of the oscillating horizontal shaft 61 pass through the ends of the fork arm 43, and a cam 62 is fixedly connected to the end of the oscillating horizontal shaft 61. One end of the cam 62 is always slidably placed in the slot 311 of the follower foot column 31. Two symmetrical vibrating arms 63 are fixedly connected in the oscillating horizontal shaft 61. A connecting rod 64 is fixedly connected between the ends of the vibrating arms 63. A sleeve shaft 65 is slidably mounted on the connecting rod 64. The end of the sleeve shaft 65 is vertically slidably inserted into the turntable 44 near the edge.

[0023] In Embodiment 2, based on Embodiment 1, the two ends of the connecting rod 64 are respectively rotatably sleeved with support arms 66, and the other end of the support arm 66 is rotatably installed with a hanging member 67. The two ends of the hanging member 67 are vertically provided with hanging shafts 671, and the hanging shafts 671 are respectively slidably inserted into both sides of the bearing seat 32. The hanging member 67 slides in the bearing seat 32 through the hanging shafts 671.

[0024] The following provides further explanation and description of the functions and effects of each structure mentioned above, to help those skilled in the art better understand the technical solution: Power is provided by a drive mechanism (drive motor 51, drive shaft 52, worm gear 53). Specifically, after the drive motor 51 starts, it drives the drive shaft 52 to rotate, which in turn causes the worm gear 53 fixed on it to rotate synchronously. The worm gear 53 meshes with the worm wheel 42 fixed in the middle of the transmission shaft 41 of the oscillation transmission mechanism, thereby efficiently and stably transmitting and changing the direction of the rotational motion of the drive shaft 52, driving the transmission shaft 41 to rotate laterally on the base 2. Turntables 44 are fixedly installed at both ends of the transmission shaft 41, and the rotation of the turntables 44 is the key input for subsequent oscillation. At the same time, a "U"-shaped fork arm 43 is rotatably fitted on the transmission shaft 41 inside the turntables 44. The ends of the fork arms 43 are connected to both ends of the oscillation horizontal shaft 61 of the compound oscillation mechanism, so that the rotational motion of the turntables 44 can be transmitted to the oscillation horizontal shaft 61.

[0025] The compound oscillation mechanism is the core component for achieving complex oscillation movements. The oscillating horizontal shaft 61 is longitudinally rotatably mounted on the base 2. Cams 62 are fixedly connected to both ends of the shaft, with one end of each cam 62 always slidably embedded in a slot 311 on the follower foot 31 at the bottom of the carrier 3. This design is crucial; the profile of the cam 62 determines the displacement trajectory of the carrier 3 in a specific direction, while the slot 311 precisely constrains and guides the movement of the cam 62, ensuring the accuracy and repeatability of the oscillation trajectory. In the middle of the oscillating horizontal shaft 61, two symmetrical vibrating arms 63 are fixedly connected, with a connecting rod 64 fixedly connected between the ends of the vibrating arms 63. A sleeve 65 is slidably mounted on the connecting rod 64, and the end of the sleeve 65 is vertically slidably inserted into the turntable 44 near its edge. Therefore, when the turntable 44 rotates, its eccentric motion pushes and pulls the connecting rod 64 through the sleeve 65, forcing the connecting rod 64 to slide along the sleeve 65 and causing the vibrating arms 63 and the oscillating horizontal shaft 61 to reciprocate. The oscillation of the horizontal axis 61 directly drives the cams 62 at both ends to move along a predetermined trajectory within the slots 311, thereby causing the carrier 3 to oscillate in one dimension (e.g., back-and-forth or left-and-right). Furthermore, both ends of the connecting rod 64 are rotatably sleeved with support arms 66, and the other end of the support arms 66 is rotatably mounted with a hanger 67. The hanging shafts 671 at both ends of the hanger 67 are vertically arranged and slidably inserted into the sides of the bearing seat 32 fixed to the bottom of the carrier 3. Thus, when the connecting rod 64 is driven by the turntable 44 to reciprocate, it pulls or pushes the hanger 67 through the support arms 66, and the hanger 67 slides within the bearing seat 32 via its hanging shafts 671, thereby causing the carrier 3 to oscillate in another dimension (e.g., up-and-down or in a direction perpendicular to the driving direction of the cams 62). The ingenious design of the compound oscillation mechanism (oscillation horizontal axis 61, cam 62, vibration arm 63, connecting rod 64, sleeve shaft 65, support arm 66, hanger 67, hanger shaft 671) enables the rotational motion from a single drive source (drive motor 51) to be synthesized into a compound oscillation motion of the carrier 3 in two vertical directions through the coordinated action of multiple components such as turntable 44, connecting rod 64, support arm 66, and cam 62.

[0026] As the mounting platform for the oilstone frame, the bottom structure design of the carrier 3 is crucial for achieving stable oscillation. At each of its four corners, a follower post 31 is vertically fixed downwards. The slots 311 on the follower post 31 accommodate and guide the movement of the cam 62. A pull pin 312 fixed to the lower outer wall of the follower post 31 is connected via a tension spring 21 to the other end of a tension spring 21 fixed to the front and rear side walls of the base 2. These tension springs 21 serve multiple functions: first, they provide the carrier 3 with the necessary elastic restoring force, ensuring that the carrier 3 returns to its initial or equilibrium position after the force of the oscillation mechanism disappears; second, they balance part of the load, making the movement smoother; and finally, they maintain the contact pressure between the cam 62 and the slots 311, ensuring reliable motion transmission. The bearing seat 32 fixed to the bottom of the carrier 3 provides a precise sliding track for the hanging shaft 671 of the hanger 67, allowing the hanger 67 to smoothly drive the carrier 3 in the second dimension of oscillation.

[0027] The base 1 serves as the supporting foundation for the entire mechanism, with the base 2 fixed upon it. This provides a stable mounting platform for the oscillation transmission frame 4, drive frame 5, oscillation transmission mechanism, drive mechanism, and the oscillation horizontal axis 61 in the composite oscillation mechanism, ensuring the accuracy of the relative positions of each component and overall rigidity. The oscillation transmission frame 4 and drive frame 5, as structural frames, primarily support and position the oscillation transmission mechanism and drive mechanism they contain. Their vertically distributed design optimizes the spatial layout and power transmission path.

[0028] In summary, this mechanism provides power through a drive mechanism, which converts and transmits the motion via an oscillation transmission mechanism (transmission shaft 41, worm gear 42, fork arm 43, turntable 44). This motion is then linked to a compound oscillation mechanism (oscillation horizontal shaft 61, cam 62, vibration arm 63, connecting rod 64, sleeve shaft 65, support arm 66, hanger 67, hanger shaft 671). By cleverly utilizing the constrained movement of the cam 62 within the slot 311 and the lever and sliding combination of the connecting rod 64, support arm 66, and hanger 67, the mechanism ultimately drives the carrier 3 to generate a specific and controllable compound oscillation motion. The tension spring 21 provides the tension for reset and maintaining contact, the follower foot 31 and shaft seat 32 provide precise guidance for the oscillation, while the base 1 and base 2 form a stable support foundation.

[0029] Working principle: After the drive motor 51 is started, it drives the drive shaft 52 to rotate, and the worm 53 fixed in the middle of the drive shaft 52 rotates accordingly. The worm 53 meshes with the worm wheel 42 fixed in the middle of the transmission shaft 41 of the oscillation transmission mechanism, efficiently and stably converting the longitudinal rotational motion of the drive shaft 52 into the lateral rotational motion of the transmission shaft 41. The turntables 44 fixedly mounted at both ends of the transmission shaft 41 rotate together.

[0030] The rotational motion of the turntable 44 drives the subsequent mechanisms through two key paths: First, the rotating "U"-shaped fork arm 43, mounted on the transmission shaft 41 and located inside the turntable 44, has its ends connected to both ends of the oscillating horizontal shaft 61 of the compound oscillation mechanism, allowing the oscillating horizontal shaft 61 to oscillate fundamentally with the rotation of the turntable 44. Second, as the turntable 44 rotates, its position near the edge drives the sleeve shaft 65, which is vertically slidably inserted there, to perform an eccentric circular motion. The sleeve shaft 65 is slidably mounted on the connecting rod 64, so the eccentric motion of the sleeve shaft 65 forces the connecting rod 64 to slide along its own axis, while simultaneously driving the two symmetrical vibrating arms 63 fixedly connected to the oscillating horizontal shaft 61, thereby intensifying the reciprocating oscillation amplitude of the oscillating horizontal shaft 61. The oscillation of the oscillating horizontal shaft 61 directly drives the cams 62 fixedly connected to its two ends.

[0031] One end of the cam 62 is always slidably embedded in the vertically opened slots 311 on the follower foot posts 31 at the four corners of the bottom of the carrier 3. The contour movement of the cam 62 is precisely constrained and guided by the slots 311, thereby driving the carrier 3 to generate a first-dimensional oscillation (e.g., in the forward or backward or left and right directions). At the same time, the sliding movement of the connecting rod 64 drives the support arms 66 that are rotated and sleeved at both ends. The other end of the support arm 66 is rotatably mounted with a hanger 67. The vertical hanging shafts 671 at both ends of the hanger 67 are slidably inserted into both sides of the bearing seat 32 fixed to the bottom plane of the carrier 3. Therefore, the sliding of the connecting rod 64 pulls or pushes the hanger 67 through the support arm 66, forcing the hanger 67 to slide within the bearing seat 32 through the hanging shafts 671, thereby driving the carrier 3 to generate a second-dimensional oscillation (e.g., in the up and down direction) perpendicular to the first dimension. The power from the single drive motor 51, through the coordinated action of the above mechanisms, is finally synthesized into a composite oscillating motion that drives the carrier 3 in two vertical directions in space.

[0032] Throughout the entire operation, the tension springs 21 connected to the front and rear side walls of the base 2 are connected at their other ends to the carrier 3 via a pull pin 312 on the lower outer side wall of the follower foot 31. The tension springs 21 provide multiple functions: first, they provide the necessary elastic restoring force to the carrier 3, assisting it in returning to its balanced position; second, they balance part of the load, making the composite oscillation motion of the carrier 3 smoother; third, they continuously apply tension to ensure that the cam 62 and the slot 311 of the follower foot 31 maintain reliable contact pressure, preventing disengagement and ensuring the accuracy and reliability of motion transmission. The base 1 and the base 2 fixed on it provide a stable support foundation for the entire mechanism, while the oscillation transmission frame 4 and drive frame 5 ensure the optimization of the spatial positioning and power transmission path of the internal mechanism. Finally, the oilstone frame, installed and fixed on the carrier 3, performs a specific composite oscillation motion together with the carrier 3, achieving effective grinding or polishing of the workpiece.
