AI Technical Summary
The existing workpiece flipping mechanism has a complex structure and high manufacturing cost. Furthermore, the clamping rotation and movement use different power inputs, which increases the overall structural complexity and cost.
Using a drive cylinder as the power input, the workpiece is moved laterally while being rotated in conjunction with the gripper cylinder, thus achieving synchronous flipping of the workpiece, simplifying the structure and reducing manufacturing costs.
It achieves synchronous linkage in the workpiece flipping process, simplifies structural design, and reduces manufacturing costs.

Abstract
Description
An automatic workpiece flipping mechanism Technical Field
[0001] This utility model relates to the field of automated tooling technology, specifically to an automatic workpiece flipping mechanism. Background Technology
[0002] Modern mechanical manufacturing and processing equipment is gradually developing towards automation, digitalization, high precision, and wide applicability. In current production processes, due to the demands of workpiece processing, double-sided machining is often required. In such cases, it is necessary to use equipment to process one side of the workpiece first, then flip it to the other side, and then continue to the next processing step. Flipping the workpiece to the next step involves two actions: rotation and translation. Existing tooling uses separate power inputs to drive the clamping, rotation, and movement of the workpiece, resulting in a complex overall structure and high manufacturing costs. Summary of the Invention
[0003] The purpose of this invention is to provide an automatic workpiece flipping mechanism to solve the problems mentioned in the background art.

[0005] Preferably, two L-shaped limiting blocks are fixedly installed on the base plate, and the limiting blocks are used to constrain the lateral travel of the moving seat.
[0006] Preferably, a roller is mounted on the end of the drive pin, and the roller rolls along the oblique elongated hole to reduce the moving resistance of the drive pin.
[0007] Compared with the prior art, the beneficial effects of this utility model are: this utility model uses a driving cylinder as the power input, and the gripper cylinder clamps the workpiece and moves it laterally while rotating in linkage. The structure of this mechanism is simple and easy to process and manufacture. Attached Figure Description

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0012] Please refer to Figures 1-2. This utility model provides a technical solution: an automatic workpiece flipping mechanism, including a base plate 1, a cylinder support 2 fixedly installed on the upper side of the base plate 1, a drive cylinder 3 along the length direction installed on the cylinder support 2, a linear guide rail 4 along the length direction fixedly installed on the upper side of the base plate 1, a matching slider 5 slidably connected on the linear guide rail 4, an L-shaped movable seat 6 fixedly installed on the slider 5, the front end of the piston rod of the drive cylinder 3 fixedly connected to the movable seat 6, and the drive cylinder 3 pushes the movable seat 6 to move laterally along the linear guide rail 4.
[0013] The movable seat 6 is equipped with a longitudinally horizontally penetrating rotating shaft 10, which is connected to the movable seat 6 via bearings. A gripper cylinder 9 is fixedly mounted at the front end of the rotating shaft 10, and a gripper is mounted at the actuating end of the gripper cylinder 9. The gripper cylinder 9 drives the two grippers to open and close to clamp the workpiece. Two L-shaped limiting blocks 13 are fixedly mounted on the base plate 1 to constrain the lateral travel of the movable seat 6. A radial connecting rod is fixedly mounted at the tail end of the rotating shaft 10, and a perpendicular drive pin 11 is fixedly connected to the outer side of the connecting rod. A vertical plate 7 is fixedly mounted on the back side of the base plate 1, and the vertical plate 7 has an oblique elongated hole 8. The drive pin 11 is inserted into the oblique elongated hole 8, and a roller 12 is mounted at the end of the drive pin 11. The roller 12 rolls along the oblique elongated hole 8 to reduce the moving resistance of the drive pin 11. When the drive pin 11 moves along the oblique elongated hole 8, the connecting rod and the rotating shaft 10 flip, thereby causing the gripper cylinder 9 and the workpiece to rotate synchronously.
[0014] Working principle: During use, the workpiece is held by the gripper cylinder 9, and the drive cylinder 3 pushes the moving seat 6 to move laterally to the left. The drive pin 11 moves along the oblique elongated hole 8. At the same time, the connecting rod, rotating shaft 10, and gripper cylinder 9 rotate, realizing the flipping of the workpiece. The lateral movement and flipping of this mechanism are synchronized and linked. Only one drive cylinder 3 is needed as the power input, which simplifies the structure and reduces manufacturing costs.
[0015] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
