Technical Field

[0001] This invention is a flip-up automatic clamping device for air rudders, used for clamping air rudders 9 to be processed. Background Technology

[0002] With advancements in industrial technology and improvements in product quality, the dimensions of mechanical parts are becoming increasingly complex. As industry develops, the service requirements and design standards for mechanical parts are constantly rising in the field of mechanical design and manufacturing, leading to increasing demand for batch production and higher requirements for automated and intelligent processing. Meanwhile, air rudders are a crucial product in the aerospace industry, demanding high processing quality. After being coated with a composite material, both sides require machining to meet usage requirements; this process is difficult to clamp and automate. Summary of the Invention

[0003] In order to solve the problems existing in the prior art, the present invention provides a flip-up automatic clamping device for air rudders.

[0004] A flip-up automatic clamping device for an aerodynamic rudder is characterized by comprising a fixed base plate 1, pneumatic fingers 2, at least two rotary pressing cylinders 3, at least two linear cylinders 4, flexible tooling fixtures 5, hole position adapter pins 6, and grippers 7. Multiple flexible tooling fixtures 5, pneumatic fingers 2, linear cylinders 4, and rotary pressing cylinders 3 are provided on the upper surface of the fixed base plate 1. The pneumatic fingers 2 are fixed to the fixed base plate 1. Multiple flexible tooling fixtures 5 are provided on three sides of the pneumatic fingers 2. At least two rotary pressing cylinders 3 and at least two linear cylinders 4 are provided around the periphery of the multiple flexible tooling fixtures 5. A gripper 7 is installed on each side of the pneumatic fingers 2, and a hole position adapter pin 6 is installed on a protrusion on the outer side of the gripper 7.

[0005] During operation, the air rudder 9 to be processed is placed on multiple flexible tooling fixtures 5. The height of the multiple flexible tooling fixtures 5 is adjusted, and the hole position adapter pin 6 is inserted into the positioning hole 92 in the portal frame 91 of the air rudder 9 to be processed. The pneumatic finger 2 extends, so that the hole position adapter pin 6 on both sides of the pneumatic finger 2 presses against the portal frame 91, positioning the air rudder 9 to be processed and locking the height of the multiple flexible tooling fixtures 5. Then, the pressure block of the rotary pressing cylinder 3 is pressed into the positioning groove 93 at both ends of the air rudder 9 to be processed, so that the rotary pressing cylinder 3 and the multiple flexible tooling fixtures 5 clamp the air rudder 9 to be processed. The linear cylinder 4 on the other side is pressed against the other side of the air rudder 9 to be processed, so that the positioning of the air rudder 9 to be processed cannot be shaken, thus completing the air rudder clamping.

[0006] At least five of the aforementioned flexible tooling fixtures 5 are fixedly installed on the fixed base plate 1, each including multiple metal pillars, springs, metal frames and locking mechanisms at the top.

[0007] A shim is placed on the upper surface of each metal column of the flexible tooling fixture 5. The shim is made of a material with low hardness to prevent damage to the contact surface of the air rudder 9 to be machined.

[0008] The top of the linear cylinder 4 is provided with a gasket made of a material with low hardness to prevent damage to the contact surface of the air rudder 9 to be machined.

[0009] The pneumatic finger 2 has multiple protrusions at both ends in the extension direction. The gripper 7 has a groove at one end and a groove at the other end. The groove at one end of the gripper 7 is adapted to the multiple protrusions at both ends of the pneumatic finger 2. A gripper 7 is fixedly installed at each end of the pneumatic finger 2. The hole position adapter pin 6 is a sleeve with a defined shape. The hole position adapter pin 6 is fitted on the protrusion on the outside of the gripper 7. The hole position adapter pin 6 also cooperates with the positioning hole 92 in the door frame 91.

[0010] The beneficial effects of this invention are:

[0011] 1) In order to improve the degree of automation and processing quality, this invention designs an automatic clamping fixture that can process both sides of the air rudder separately, so as to realize the rapid clamping and positioning of the air rudder. The main advantage of this invention is that the clamped air rudder surface to be processed is not damaged by the fixture.

[0012] 2) The present invention uses a flexible tooling fixture to contact the surface of the air rudder to be processed, providing auxiliary support, enhancing the rigidity of the clamping, improving the machinability of the workpiece, and facilitating workpiece processing.

[0013] 3) The present invention adopts a symmetrical layout to realize the air rudder can be flipped and clamped, saving clamping space.

[0014] 4) This invention uses four metal holes on the air rudder for positioning, which is accurate and easy to calibrate.

[0015] 5) This invention uses a hole-position adapter pin to unify the four holes of different diameters of the air rudder, enabling the air rudder to be installed in a flip-up manner. Attached Figure Description

Detailed Implementation

[0023] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0024] A flip-up automatic clamping device for air rudders includes a fixed base plate, pneumatic fingers, a rotary pressing cylinder, a linear cylinder, a flexible tooling fixture, a hole-positioning adapter pin, grippers, a solenoid valve, an air source, and air pipes. The pneumatic fingers, rotary pressing cylinder, linear cylinder, and flexible tooling fixture are mounted on the fixed base plate according to their dimensional characteristics. The hole-positioning adapter pin is fixed to the positioning holes within the air rudder's portal frame, and the grippers are mounted on the pneumatic fingers. The air source is connected to the solenoid valve via air pipes, and the solenoid valve is connected to the pneumatic components via air pipes to control the air intake and exhaust of the pneumatic components, thereby enabling the installation and removal of the air rudder.

[0025] The aforementioned flip-up automatic clamping device for air rudders is characterized by a hole-position adapter pin having a boss at one end and a groove at the other end. The outer diameter of the boss mates with the air rudder hole, and the inner diameter of the groove mates with the gripper boss. During clamping, pneumatic fingers drive the gripper boss to engage with the hole-port of the hole-position adapter pin; during release, the gripper disengages from the hole-position adapter pin.

[0026] The aforementioned flip-up automatic clamping device for air rudders is characterized in that, during clamping, a rotating pressing cylinder presses into the groove at the tail end of the air rudder, thereby assisting in positioning.

[0027] The aforementioned flip-up automatic clamping device for air rudders is characterized in that, during clamping, a linear cylinder presses against the upper edge of the air rudder to assist in positioning.

[0028] The aforementioned flip-up automatic clamping device for air rudders is characterized by a flexible tooling fixture that can change shape according to different workpiece surfaces and has a locking function. During clamping, the flexible tooling fixture can change according to the changes in the lower plane dimensions of the air rudder and lock its position, thus playing an auxiliary support role.

[0029] The aforementioned automatic clamping device for a reversible air rudder is characterized in that a rotary pressing cylinder, a linear cylinder, and a flexible tooling fixture are respectively arranged at symmetrical positions on a fixed base plate to achieve reliable clamping when the air rudder is flipped and another plane is machined.

[0030] Example:

[0031] The present invention will be further described below with reference to the accompanying drawings and embodiments. The present invention includes, but is not limited to, the following embodiments.

[0032] like Figure 1 As shown, a flip-up automatic clamping device for an air rudder includes a fixed base plate 1, pneumatic fingers 2, a rotary pressing cylinder 3, a linear cylinder 4, a flexible tooling fixture 5, a hole-positioning adapter pin 6, and a gripper 7. The pneumatic fingers 2, rotary pressing cylinder 3, linear cylinder 4, and flexible tooling fixture 5 are mounted on the fixed base plate according to their dimensional characteristics. The hole-positioning adapter pin 6 is fixed to the air rudder hole, the gripper 7 is mounted on the pneumatic fingers 2, and the hole-positioning adapter pin 6 is mounted on the positioning hole within the air rudder gantry frame. Figure 2 , Figure 3 As shown. During clamping, the pneumatic device is ventilated, and the pneumatic finger 2 extends, driving the gripper 7 to extend and engage with the pin hole of the adapter pin 6 installed on the air rudder, completing the main clamping process, as shown. Figure 5 As shown.

[0033] At the same time, the rotary pressing cylinder 3 is activated, and the pressing block is pressed into the groove at the tail end of the air rudder; the linear cylinder 4 extends and presses against the upper edge of the air rudder; the flexible tooling fixture 5 extends and locks itself after contacting the lower surface of the air rudder, playing an auxiliary positioning role.

[0034] During disassembly, the pneumatic device is vented in reverse, the pneumatic finger 2 retracts, driving the gripper 7 to retract, and at the same time the rotating pressing cylinder 3 rotates and rises, releasing the tail clamp of the air rudder. The linear cylinder 4 retracts, releasing the upper edge clamp of the air rudder. At this time, the air rudder can be released from clamping and removed.

[0035] After the air rudder is flipped and placed in the installation position, the pneumatic device is energized, and the symmetrical rotating downward cylinder 3, linear cylinder 4, and flexible tooling fixture 5 are activated to complete the air rudder clamping. Figure 6 As shown.
