Technical Field

[0002] Micro-arc oxidation, also known as micro-plasma oxidation or anodic spark deposition, is a highly efficient surface modification technology. Micro-arc oxidation of the actuator cylinder cavity is an advanced surface treatment technology. This technology utilizes the principles of plasma chemistry and electrochemistry to generate micro-area arc discharge phenomena on the surface of non-ferrous metals and their alloys, thereby growing a ceramic layer in situ on the substrate surface. Micro-arc oxidation technology can solve the problems of uneven film formation caused by electric field shielding effect and uneven electric field distribution on the inner wall. Currently, each diameter requires a fixture for micro-arc oxidation of actuator cylinders, and existing fixtures also have certain limitations on the length of the actuator cylinder.

Arc-shaped clamping plate. Detailed Implementation

[0022] This utility model is achieved through the following technical solution.

[0023] like Figures 1-3As shown, a tooling fixture for micro-arc oxidation of the inner cavity of a double-cylinder actuated cylinder, in an optional embodiment, includes a worktable 11, servo motors 12, bidirectional screws 13, a movable frame 14, and a clamping assembly 15. Two servo motors 12 are threadedly connected to one side of the worktable 11. The inner side of the bidirectional screw 13 is fixedly connected to the motor shaft of the servo motors 12 via a coupling. The movable frame 14 is threadedly sleeved on the outside of the bidirectional screw 13. The clamping assembly 15 is fixedly connected to the top of the movable frame 14. Detection components 2 are also provided on both sides of the top of the worktable 11. The clamping assembly 15 includes an electric telescopic rod 151, a push rod 152, and an arc-shaped clamping plate 153. The output end of the electric telescopic rod 151 is fixedly connected to one end of the push rod 152. The outer side of the push rod 152 is fixedly connected to the middle of the protruding end of the arc-shaped clamping plate 153. The concave end of the arc-shaped clamping plate 153 abuts against the surface of the outer actuated cylinder.

[0024] In this implementation scheme: the clamp can be freely adjusted according to the different lengths of the actuator. During operation, the servo motors 12 on both sides are started through the control terminal. The servo motors 12 drive the bidirectional screw 13 to rotate. Since the movable frame 14 is always embedded inside the worktable 11, the worktable 11 plays a role in hindering the rotation of the movable frame 14. With the cooperation of the screw with the threaded surface of the built-in threaded groove 7 and the threaded surface of the bidirectional screw 13, the two sets of movable frames 14 can drive the top arc-shaped clamping plate 153 to expand or retract, so that this device can be adapted to actuators of different lengths, improving the practicality of this device.

[0025] Furthermore:

[0026] like Figure 1 , Figure 3 and Figure 4 As shown:

[0027] In an optional embodiment: the detection component 2 includes a support frame 21, a hollow frame 22 and an infrared transmitter 23. The hollow frame 22 is fixedly connected to the opposite side surface of the support frame 21, and the infrared transmitter 23 is movably connected to the outside of the hollow frame 22. The hollow frame 22 is also provided with a hydraulic cylinder 3, a drive rod 4 and a slider 5. The piston end of the hydraulic cylinder 3 is fixedly connected to one end of the drive rod 4, and the slider 5 is fixedly connected to the top of the drive rod 4. The support frame 21 is also provided with a signal receiver 6 on the side near the infrared transmitter 23. The bottom of the movable frame 14 is provided with a threaded groove 7 that matches the size of the bidirectional screw 13.

[0028] In this embodiment: During the clamping process, the electric telescopic rod 151 at the top of the electrically activated movable frame 14 pushes the push rod 152 at its output end. The push rod 152 pushes the arc-shaped clamping plate 153 closer together. The four sets of arc-shaped clamping plates 153 fully abut against the surface of the actuating cylinder to achieve a secure clamping effect. On the other hand, under the clamping effect, the hydraulic cylinder 3 inside the hollow frame 22 is driven. Its piston end pushes the drive rod 4. The drive rod 4 pushes the slider 5. The slider 5 drives the infrared emitter 23 on the outside to move up and down along the inner wall of the groove. The infrared radiation energy of the material surface is used to detect defects in the material. The signal is fed back to the control circuit through the signal receiver 6 and imaged, thereby effectively judging whether the micro-arc oxidation is qualified and ensuring product quality.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
