Description

Technical Field

[0001] This utility model relates to the field of workpiece clamping and flipping technology, and in particular to a workpiece clamping and flipping fixture that can be rotated 90 degrees. Background Technology

[0002] In industrial fields such as machining, automotive parts manufacturing, hardware assembly, and surface treatment, workpieces often need to be rotated 90 degrees during processing (e.g., switching between horizontal and vertical workstations). For example, in welding processes, workpieces need to be rotated to complete multi-faceted weld connections; in milling, the vertical and horizontal surfaces of the workpiece need to be switched; and in painting processes, workpieces need to be rotated to ensure uniform coating coverage. In this process, "stable clamping" and "precise rotation" of the workpiece are core requirements for ensuring machining accuracy, production efficiency, and operational safety.

[0003] Existing workpiece clamping and flipping technologies still have many shortcomings. Traditional small fixtures mostly rely on manual clamping and flipping of workpieces, which is not only labor-intensive but also slow. More importantly, during manual flipping, the workpiece's center of gravity may shift, causing it to fall and posing safety hazards such as equipment collisions and personnel injuries. Therefore, we propose a workpiece clamping and flipping fixture that can be rotated 90 degrees. Utility Model Content

[0004] The main purpose of this utility model is to provide a workpiece clamping and flipping fixture that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A workpiece clamping and flipping fixture with a 90-degree rotation includes an adjusting frame. One end of the adjusting frame has a mounting groove, within which a servo motor is installed. A mounting plate is mounted on the bottom surface of the mounting groove. A brake cylinder is mounted on the upper surface of the mounting plate. A brake disc is mounted at the output end of the servo motor. A mounting frame is mounted on the bottom surface of the brake disc. Vertical plates are symmetrically arranged on the bottom surface of the mounting frame. Electric telescopic rods are symmetrically hinged to one side of the mounting frame. A rotating column is inserted through one side of the vertical plates. A connecting piece is rotatably connected to the output end of the electric telescopic rod. A rotating frame is mounted at one end of the rotating column, and a clamping frame is located in the middle of the rotating frame.

[0006] Preferably, the clamping frame is provided with an electric push rod, the bottom surface of the inner wall of the clamping frame is symmetrically provided with sliding grooves, a connecting block is slidably connected in the sliding groove, the bottom surface of the clamping frame is symmetrically provided with a slide rail, the surface of the slide rail is slidably connected with a sliding block, and the bottom surface of the sliding block is symmetrically provided with grippers.

[0007] By adopting the above technical solution, the servo motor and brake cylinder are integrated into the mounting slot of the adjustment frame, resulting in a compact structure that saves space. The servo motor provides precise angle control, while the brake cylinder can achieve fast and reliable locking at any position, preventing rotation due to external force or its own weight during handling or clamping, thus ensuring stability and safety during processing or transfer.

[0008] Preferably, the brake disc has a clamping surface on the circular edge of the brake cylinder, one side of the upright plate is rotatably engaged with the rotating column, the clamping surface of the brake disc is covered with a wear-resistant friction material, and the rotating contact surface of the upright plate is inlaid with a bronze bushing.

[0009] Preferably, one end of the connector is fixedly connected to the circumferential side of the rotating column, and the rotating column is fixedly connected to one side of the rotating frame.

[0010] Preferably, the shape and size of the clamping frame are adapted to the mounting frame and the two sets of upright plates, and rotate within the mounting frame and the two sets of upright plates.

[0011] Preferably, the upper surface of the sliding block is fixedly connected to the bottom surface of the connecting block, and both the sliding block and the connecting block are made of high-strength steel and are fixed by bolts.

[0012] By adopting the above technical solution, both the sliding block and the connecting block are made of high-strength steel, ensuring that the connection part will not deform or break when subjected to clamping force. The bolt fixing is a reliable and detachable connection method, which not only ensures the firmness of the connection, but also facilitates the replacement and maintenance of wear parts in the future.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model integrates the servo motor and brake cylinder into the mounting slot of the adjustment frame, forming a compact drive and braking module. The servo motor ensures high-precision control of the tilting angle, while the brake cylinder enables fast and reliable mechanical locking at any position. This design not only significantly saves installation space but also fundamentally solves the problem of accidental rotation caused by external forces or workpiece weight during handling or processing, greatly improving the operational stability and safety of the entire fixture under high-speed and high-load conditions.

[0014] 2. By adopting a dual drive structure of "servo motor plus dual electric telescopic rods", the flipping action is realized. The servo motor can drive the mounting frame and the components below to rotate as a whole, providing a basic angle adjustment for flipping; while the symmetrically arranged electric telescopic rods push the rotating column to drive the rotating frame to flip precisely through synchronous extension and retraction. This method provides strong thrust and is suitable for flipping heavy work. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] Please see Figure 1-4 This utility model provides a technical solution: A workpiece clamping and rotating fixture with a 90-degree rotation includes an adjusting frame 1. One end of the adjusting frame 1 has a mounting groove 10. A servo motor 101 is installed in the mounting groove 10. A mounting plate 102 is installed on the bottom surface of the mounting groove 10. A brake cylinder 103 is installed on the upper surface of the mounting plate 102. A brake disc 20 is installed at the output end of the servo motor 101. A mounting frame 2 is installed on the bottom surface of the brake disc 20. Vertical plates 202 are symmetrically arranged on the bottom surface of the mounting frame 2. Electric telescopic rods 201 are symmetrically hinged to one side of the mounting frame 2, and one side of the vertical plates 202 is inserted into them. There is a rotating column 203, and the output end of the electric telescopic rod 201 is rotatably connected to the connector 204. One end of the rotating column 203 is provided with a rotating frame 3, and the middle of the rotating frame 3 is provided with a clamping frame 31. An electric push rod 310 is provided inside the clamping frame 31. The bottom surface of the inner wall of the clamping frame 31 is symmetrically provided with a sliding groove 311. A connecting block 312 is slidably connected in the sliding groove 311. The bottom surface of the clamping frame 31 is symmetrically provided with a slide rail 313. A sliding block 314 is slidably connected to the surface of the slide rail 313. The bottom surface of the sliding block 314 is symmetrically provided with a gripper 315.

[0021] In this embodiment, the brake disc 20 has a clamping surface on the circular edge of the brake cylinder 103. One side of the upright plate 202 is rotatably engaged with the rotating column 203. The clamping surface of the brake disc 20 is covered with a wear-resistant friction material. The rotating contact surface of the upright plate 202 is inlaid with a bronze bushing. One end of the connector 204 is fixedly connected to the circumferential side of the rotating column 203. The rotating column 203 is fixedly connected to one side of the rotating frame 3. The shape and size of the clamping frame 31 are adapted to the mounting frame 2 and the two sets of upright plates 202, and it rotates within the mounting frame 2 and the two sets of upright plates 202. The upper surface of the sliding block 314 is fixedly connected to the bottom surface of the connecting block 312. Both the sliding block 314 and the connecting block 312 are made of high-strength steel and are fixed by bolts.

[0022] Through the above scheme: the brake cylinder 103 first releases the clamp on the brake disc 20, and the servo motor 101 starts. The output shaft of the servo motor 101 directly drives the brake disc 20 to rotate. The brake disc 20 is fixedly connected to the mounting frame 2, thereby driving the entire mounting frame 2 and all the components below it to rotate together. Two symmetrically arranged electric telescopic rods 201 extend or retract synchronously. The tail of the electric telescopic rod 201 is hinged to the mounting frame 2, and its output end pushes the connector 204, which is fixedly connected to the rotating column 203, through the connector 204. Since the rotating column 203 is supported in the vertical plate 202, this thrust is converted into torque, forcing the rotating column 203 to rotate. The rotating column 203 drives the rotating frame 3 and the clamping frame 31 to rotate within the frame formed by the mounting frame 2 and the vertical plate 202, realizing the flipping. This method provides strong thrust and is suitable for flipping heavy work. At the same time, the electric push rod 310 is activated, which drives the sliding block 314 to move synchronously in the opposite direction along the slide rail 313 through the connecting block 312, so that the gripper 315 installed at the bottom of the sliding block 314 firmly clamps the workpiece from one side.

[0023] It should be noted that the brake cylinder 103 first releases the clamp on the brake disc 20, and the servo motor 101 starts. The output shaft of the servo motor 101 directly drives the brake disc 20 to rotate. The brake disc 20 is fixedly connected to the mounting frame 2, thereby driving the entire mounting frame 2 and all the components below it to rotate together. Two symmetrically arranged electric telescopic rods 201 extend or retract synchronously. The tail of the electric telescopic rod 201 is hinged to the mounting frame 2, and its output end pushes the connector 204, which is fixedly connected to the rotating column 203, through the connector 204. Since the rotating column 203 is supported in the upright plate 202, this thrust is converted into torque, forcing the rotating column 203 to rotate. The rotating column 203 drives the rotating frame 3 and the clamping frame 31 to rotate within the frame formed by the mounting frame 2 and the upright plate 202, realizing the flipping. This method provides strong thrust and is suitable for flipping heavy work. At the same time, the electric push rod 310 is activated, which drives the sliding block 314 to move synchronously in the opposite direction along the slide rail 313 through the connecting block 312, so that the gripper 315 installed at the bottom of the sliding block 314 firmly clamps the workpiece from one side.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
