Description

Technical Field

[0001] This invention relates to the field of industrial automation equipment technology, and more particularly to a tilting mechanism. Background Technology

[0002] As the manufacturing industry moves towards intelligence and automation, flipping fixtures are needed on production lines in industries such as metal processing, special casting, and hazardous waste treatment when heavy workpieces require precise angle adjustment and safe transfer. In actual use, similar flipping fixtures still have many defects, such as: the traditional flipping device of the traditional flipping fixture has insufficient positioning accuracy, which leads to the risk of collision; the simple ratchet mechanism has obvious return error; the cumulative deviation after multiple flips can easily cause equipment damage; at the same time, the traditional flipping fixture has low manual operation efficiency and prominent safety hazards; the flipping operation that requires multiple people to complete has blind spots in command; and the hydraulic system leaks oil, which pollutes the workshop environment. Therefore, it is necessary to design a flipping fixture. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention provides a flipping mechanism.

[0004] This invention is achieved using the following technical solution: a flipping mechanism, comprising a column, a rotary motor fixedly connected inside the column, a lifting motor fixedly connected to the top of the column, a reduction motor fixedly connected to the right side of the rotary motor, a lifting lead screw fixedly connected to the bottom of the lifting motor, a positioner box fixedly connected to the right side of the reduction motor, a pinion gear fixedly connected to the right side of the positioner box, a large gear meshing with the right side of the pinion gear, a clamping seat fixedly connected to the right side of the large gear, a linear guide fixedly connected inside the clamping seat, a clamping ring fixedly connected to the right side of the clamping seat, a servo electric cylinder fixedly connected to the surface of the clamping seat, a workpiece transport vehicle connected to the right side of the column, and a universal joint rotatably connected to the top of the workpiece transport vehicle.

[0005] Through the above technical solution, a rotary motor is fixedly connected inside the column. Since the rotary motor is fixedly connected to the small gear through the reduction motor, the clamp seat fixedly connected to the large gear can be controlled to rotate through the rotary motor, thereby facilitating the rotation of the workpiece.

[0006] As a further improvement to the above solution, two columns are provided, which are symmetrically fixed on both sides of the workpiece transport vehicle. Two clamp seats are provided, which are installed on one side of the column.

[0007] With the above technical solution, two columns are provided, and the firmness of clamping the workpiece is improved by providing two independent clamping seats.

[0008] As a further improvement to the above scheme, two small gears and two large gears are provided, and the small gears and large gears are respectively fixed on one side of the displacement box.

[0009] Through the above technical solution, two small gears and two large gears are provided. The meshing between the small gears and the large gears forms a gear reduction ratio, which reduces the high speed to the low speed required for the workpiece to be turned, making the turning of the workpiece smoother.

[0010] As a further improvement to the above solution, two clamp seats are provided, which are respectively fixed on one side of the small gear and the large gear. Multiple linear rails are provided, which are symmetrically installed on the surface of the clamp seats.

[0011] With the above technical solution, two clamping seats are provided. The clamping ring is moved by the linear guide to clamp the workpiece, which replaces the simple sleeve sliding and makes the clamping ring run more smoothly, with higher precision and less resistance.

[0012] As a further improvement to the above solution, two clamping rings are provided. The clamping rings are fixed on one side of the clamping seat, and the two ends of the clamping rings can be flipped. The inner wall of the clamping rings is fixed with rubber skin.

[0013] With the above technical solution, two clamping rings are provided. Since the two ends of the clamping rings can be flipped, it is convenient to clamp the workpiece.

[0014] As a further improvement to the above solution, two locking buckles are provided, each of which is fixed to one end of the clamp ring.

[0015] With the above technical solution, two locking buckles are provided. By installing independent locking buckles at both ends of the clamping ring, the firmness of the workpiece clamping is improved.

[0016] As a further improvement to the above solution, multiple universal wheels are provided, and the universal wheels are symmetrically fixed on the top of the workpiece transport vehicle.

[0017] Through the above technical solution, multiple universal wheels are provided. By installing multiple universal wheels on the top of the workpiece transport vehicle, the workpiece can be freely turned and its angle adjusted in place, which improves the flexibility of the equipment.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention uses clamping seats and clamping rings installed on one side of two columns to simultaneously clamp and position the workpiece from both sides, ensuring uniform force on the workpiece. This effectively counteracts the eccentric load and torsional force generated during flipping and lifting, preventing workpiece swaying and displacement, and improving workpiece stability during flipping. Simultaneously, because the rotary motor is connected to a pinion gear via a reduction motor and a positioner box, and the pinion gear meshes with a large gear, the rotary motor controls the mechanical transmission between the pinion and large gears, rapidly flipping the clamping seats fixed to the large gear. With the cooperation of a servo cylinder and linear guide, the clamping rings automatically clamp and release the workpiece, eliminating the need for manual assistance in handling and flipping the workpiece. The entire process is automated, effectively reducing process time and improving production efficiency.

[0019] This invention features a clamping ring with flip-open and lockable ends, enabling quick opening and locking without the need for inserting a sleeve through the workpiece end. This simplifies workpiece loading and unloading and adapts to workpieces of various shapes. A rubber layer on the inner wall of the clamping ring increases gripping friction, prevents workpiece slippage, and buffers clamping force, avoiding rigid contact that could scratch the workpiece surface. This enhances equipment safety and strengthens workpiece protection. Multiple universal joints on the top of the transport vehicle allow for free fine-tuning of the workpiece after placement. Before clamping, the workpiece position and angle can be quickly corrected without moving the entire vehicle, reducing the difficulty of workpiece loading and improving the overall flexibility of the equipment.

[0029] The implementation principle of the flipping mechanism in this embodiment is as follows: During use, the workpiece is placed on the workpiece transport vehicle 14, and the workpiece is adjusted by the universal joint installed on the workpiece transport vehicle. After the workpiece is adjusted to a suitable position and angle, the servo electric cylinder 12 installed on the surface of the clamping seat 9 is activated, causing the servo electric cylinder 12 to push the clamping ring 11 to move and clamp the workpiece. Then, the workpiece is locked by the latches 13 at both ends of the clamping ring 11. After clamping is completed, the lifting motor 3 is activated, causing the lifting motor 3 to drive the positioner box 6 and the clamping seat 9 to move through the lifting screw 5. After moving to a suitable position, the rotary motor 2 is activated, causing the rotary motor 2 to drive the large gear 8 to rotate through the reduction motor 4 and the small gear 7. This causes the large gear 8 to drive the clamping seat 9, which is fixedly connected to it, to rotate, thereby realizing the flipping of the workpiece.
