Description

Technical Field

[0001] This utility model relates to the field of thrust rod processing technology, and in particular to a thrust rod processing fixture with adjustable angle. Background Technology

[0002] In the field of thrust rod machining, traditional tooling often uses a fixed structure, which is difficult to adapt to machining requirements at different angles and positions. Especially in the machining of thrust rods with complex curved surfaces or multiple angles, operators need to frequently adjust the workpiece position, which is not only inefficient but also prone to insufficient machining accuracy due to human error.

[0003] While some adjustable tooling exists in existing technologies, their adjustment mechanisms mostly rely on manual operation, resulting in poor adjustment accuracy, low stability, and a lack of effective positioning devices. This leads to easy workpiece displacement during processing, affecting the quality of the finished product. Therefore, there is an urgent need for a thrust rod machining tooling capable of high-precision angle adjustment, rapid positioning, and high stability to overcome the aforementioned technical bottlenecks.

[0026] Reference Figure 2 The tilting component 5 includes a fixing sleeve 51 and a hydraulic cylinder 52. The fixing sleeve 51 is welded to the outer wall of the upright 3, and the hydraulic cylinder 52 is hinged between the V-shaped positioning seat 4 and the upright 3.

[0027] During adjustment, the hydraulic cylinder 52 extends and retracts, causing the V-shaped positioning seat 4 to rotate around the hinge point at the top of the upright 3.

[0028] Reference Figure 4 The thrust rod positioning assembly 6 includes a support frame 61, a connecting frame 62, a pressure plate 63, and a cylinder 64.

[0036] Workpiece clamping: Place the push rod in the V-groove 7, start the cylinder 64, and the pressure plate 63 rotates downward under the drive of the cylinder 64, pressing the two sides of the push rod with the polyurethane gasket to complete the fixing.

[0037] Angle adjustment:

[0038] Horizontal rotation: Servo motor 24 drives worm gear 23 to rotate, which in turn drives worm wheel 22 and upright rod 3 to rotate, so that V-shaped positioning seat 4 rotates horizontally to the target angle.

[0039] Tilt angle adjustment: The hydraulic cylinder 52 extends or shortens, pushing the V-shaped positioning seat 4 to tilt around the hinge point, thereby adjusting the machining tilt angle of the thrust rod.

[0040] Machining Stage: After angle adjustment, the tooling locks all moving parts, and the machining equipment performs milling, drilling, and other operations on the thrust rod. The reinforcing rod 8 and the chassis 1 work together to resist the cutting force, ensuring machining stability.

[0041] Reset and unloading: After processing is completed, hydraulic cylinder 52 and servo motor 24 are reset to their initial positions, cylinder 64 releases pressure plate 63, and finished product is taken out.
