Description

Technical Field

[0001] This utility model relates to the field of idler roller processing technology, and in particular to a lathe idler roller mechanism with stable structure. Background Technology

[0002] The lathe idler roller mechanism is an important auxiliary device on a lathe, mainly composed of idler rollers, supports, and adjustment devices. The idler rollers are typically cylindrical with a smooth surface, used to support the workpiece during machining, reducing deformation and vibration during rotation and ensuring machining accuracy. The supports are used to fix the idler rollers, keeping them in a stable position. The adjustment device allows for flexible adjustment of parameters such as the height and angle of the idler rollers according to different workpiece dimensions and machining requirements.

[0003] The existing lathe roller support mechanism achieves a stable structure through the collaboration of multiple components. The support is made of high-strength metal material and is integrally formed. Its bottom has a large-area base that is rigidly connected to the lathe worktable. Vibration transmission is reduced by bolt fastening and shock-absorbing pads. The adjustment device uses a trapezoidal threaded screw with a locking nut. After adjustment, the position of the roller can be double-locked to avoid displacement during processing.

[0004] Traditional stabilizing mechanisms lack positioning accuracy and are prone to gap accumulation after multiple adjustments, making it impossible to continuously ensure stable clamping of the idler rollers. This affects the workpiece machining accuracy and limits the stable operation of the lathe under high-precision and high-speed conditions. Therefore, a structurally stable lathe idler roller mechanism is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a lathe roller mechanism with a stable structure, aiming to improve the problem of unstable clamping of rollers in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A structurally stable lathe roller support mechanism includes a base. Two sliding grooves are formed on the top of the base. A support frame is slidably connected inside the sliding grooves. A pneumatic cylinder is fixedly connected to the outer wall of the support frame. A push plate is fixedly connected to the drive end of the pneumatic cylinder. A follower rod is rotatably connected to one end of the push plate, and a driven rod is rotatably connected to the other end of the push plate. A semicircular ring is fixedly connected to one end of the driven rod, and a semicircular ring is fixedly connected to one end of the follower rod. An adjustment assembly is provided inside the base. As a further description of the above technical solution: The adjustment assembly includes a hydraulic cylinder, a rotating plate is fixedly connected to the drive end of the hydraulic cylinder, a follower plate is rotatably connected to one end of the rotating plate, and a driven plate is rotatably connected to the other end of the rotating plate. As a further description of the above technical solution: One end of the driven plate is fixedly connected to the second support frame, and one end of the follower plate is fixedly connected to the bottom of the first support frame; As a further description of the above technical solution: The second support frame is slidably connected to the inner wall of the slide groove, and the top of the first support frame is movably connected to a roller; As a further description of the above technical solution: The inner wall of the first semicircular ring is in contact with the outer wall of the roller, and the inner wall of the second semicircular ring is in contact with the outer wall of the roller. As a further description of the above technical solution: A fixed column is fixedly connected inside the base, and the inner wall of the fixed column is rotatably connected inside the rotating plate. As a further description of the above technical solution: The outer wall of the follower plate is slidably connected to the inside of the base, and the outer wall of the driven plate is slidably connected to the inside of the base; As a further description of the above technical solution: The bottom of the first support frame is slidably connected to the top of the base, and the bottom of the second support frame is slidably connected to the top of the base.

[0007] This utility model has the following beneficial effects: 1. In this utility model, the pneumatic cylinder is activated, and the driving end of the pneumatic cylinder pushes the push plate to move upward, causing the follower rod and driven rod to rotate around the rotating shaft as the fulcrum, driving the top semicircular ring one and semicircular ring two to move closer to the roller. After the inner walls of the two are in contact with the outer wall of the roller, the roller is locked by the symmetrical clamping force. The semicircular semicircular ring one and semicircular ring two restrict the position of the roller, while ensuring that the roller can rotate freely, thus ensuring the stable and efficient operation of the lathe roller support mechanism.

[0008] 2. In this utility model, the hydraulic cylinder is activated, and the hydraulic cylinder pushes the rotating plate to rotate around the fixed column as the axis. The rotating plate is connected to the follower plate and the driven plate through the rotating shaft to form a transmission structure. Since the follower plate and the driven plate are fixed at the bottom of the support frame one and the support frame two respectively, when the rotating plate rotates, it will drive the follower plate and the driven plate to move, thereby causing the support frame one and the support frame two to generate relative movement and complete the position adjustment.

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0012] Reference Figure 1 and Figure 4 This utility model provides an embodiment of a structurally stable lathe roller mechanism, comprising a base 1, with two sliding grooves 2 on the top of the base 1. A support frame 3 is slidably connected inside the sliding grooves 2. The sliding grooves 2 have a T-shaped cross-section, which effectively prevents the support frame 3 from detaching from the base 1 during sliding. The bottom of the support frame 3 is slidably connected to the top of the base 1 to ensure stability during sliding. A pneumatic cylinder 12 is fixedly connected to the outer wall of the support frame 3. A push plate 10 is fixedly connected to the driving end of the pneumatic cylinder 12. The push plate 10 can move up and down under the drive of the pneumatic cylinder 12. A follower rod is rotatably connected to one end of the push plate 10. 11. The other end of the push plate 10 is rotatably connected to the driven rod 14. When the push plate 10 moves up and down under the action of the pneumatic cylinder 12, the follower rod 11 and the driven rod 14 will rotate around the rotating shaft as the fulcrum. One end of the driven rod 14 is fixedly connected to a semi-circular ring 15. The inner wall of the semi-circular ring 15 is in contact with the outer wall of the roller 4. One end of the follower rod 11 is fixedly connected to a semi-circular ring 13. The inner wall of the semi-circular ring 13 is in contact with the outer wall of the roller 4. The semi-circular ring 13 and the semi-circular ring 15 can stably support and position the roller 4 under the drive of the follower rod 11 and the driven rod 14, thereby ensuring the stability of the lathe roller mechanism during operation. Reference Figure 2 and Figure 3The base 1 is equipped with an adjustment component, which includes a hydraulic cylinder 5. The drive end of the hydraulic cylinder 5 is fixedly connected to a rotating plate 6. The base 1 is fixedly connected to a fixed column 9. The rotating plate 6 is elongated. The inner wall of the fixed column 9 is rotatably connected to the inside of the rotating plate 6. The rotating plate 6 can rotate flexibly around the fixed column 9. One end of the rotating plate 6 is rotatably connected to a follower plate 7. The drive end of the hydraulic cylinder 5 performs telescopic movement, thereby driving the rotating plate 6 to rotate around the fixed column 9. One end of the rotating plate 6 is rotatably connected to the follower plate 7 via a rotating shaft. The outer wall of the follower plate 7 is slidably connected to the inside of the base 1. One end of the follower plate 7 is fixedly connected to the bottom of the support frame 3. When the follower plate 7 slides, it will drive the support frame 3 to move in the slide groove 2 at the top of the base 1. The top of the support frame 3 is movably connected to the roller 4. The other end of the rotating plate 6 is rotatably connected to the driven plate 8. The outer wall of the driven plate 8 is slidably connected to the inside of the base 1. One end of the driven plate 8 is fixedly connected to the second support frame 16. The second support frame 16 is slidably connected to the inner wall of the slide groove 2 to ensure the stability of the sliding process. The bottom of the second support frame 16 is slidably connected to the top of the base 1. Driven by the hydraulic cylinder 5, the rotating plate 6 rotates, driving the follower plate 7 and the driven plate 8 to slide, thereby allowing the support frame 3 and the second support frame 16 to move relative to each other in the slide groove 2, realizing position adjustment.

[0013] Working principle: The operator starts the hydraulic cylinder 5, which pushes the rotating plate 6 connected to it to start rotating around the fixed column 9. The two ends of the rotating plate 6 are connected to the follower plate 7 and the driven plate 8 respectively through the rotating shaft, forming a stable transmission structure. One end of the follower plate 7 is fixed to the bottom of the support frame 1 3, and one end of the driven plate 8 is fixed to the bottom of the support frame 2 16. The rotation of the rotating plate 6 drives the follower plate 7 and the driven plate 8 to rotate, which drives the support frame 1 3 and the support frame 2 16 to move relative to each other, thereby realizing the adjustment of position.

[0014] Roller 4 is placed into the slot opened in support frame 3. The shape of the slot matches the bottom contour of roller 4, providing initial positioning support for roller 4. Pneumatic cylinder 12 is activated, and the drive end of pneumatic cylinder 12 pushes push plate 10 upward. When push plate 10 rises, follower rod 11 and driven rod 14 rotate around the rotation axis. Semicircular ring 13 is fixed to the top of follower rod 11, and semicircular ring 25 is fixed to the top of driven rod 14. Semicircular ring 13 and semicircular ring 25 gradually move closer to roller 4 until the inner wall is tightly attached to the outer wall of roller 4. The roller 4 is firmly locked by symmetrical clamping force. Since semicircular ring 13 and semicircular ring 25 are semicircular, they provide all-round positioning constraints for roller 4, while not hindering its free rotation in the clamping state. This ensures that the lathe roller support mechanism can effectively fix roller 4 and meet its rotation requirements during operation, achieving stable and efficient working performance.

[0015] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
