Description

Feedback Manual Gripper

technical field

The utility model relates to a feedback gripper in the field of mechanical processing. The gripper is not only suitable for general conditions but also suitable for some special dark working environments, sealed spaces, inside complex cavities or special-shaped pipelines, and oil pollution. Waste debris, waste debris cleaning in small spaces; it is also suitable for industrial endoscopic instruments for inspection of parts and equipment in the above complex working environments.

Background technique

In real production and life, many times we will encounter situations where we need to pick up items in a small space, which brings us a lot of trouble. Such as cleaning up debris or doing other work at a distance where people cannot enter, and sometimes hurt ourselves when picking up objects. At the same time, in metal cutting, a large amount of metal shavings are often left in complex cavity holes. These remaining metal shavings are difficult to remove. The existing removal method is mainly manual removal, but it is difficult to remove completely, which greatly affects the performance and use accuracy of the product. There are also some grippers used in narrow spaces in the existing market. However, they are highly specific, not universally practical, and have relatively single functions and relatively complex structures, such as:

The gripper described in the patent "a kind of gripper" with the application number CN200520064309.3 has a complex structure, and the gripper is only suitable for industrial tooling, which has strong specificity and is very difficult for the operator's skills. Higher requirements.

The drawing gripper described in the patent "magnetic gripper" with the application number CN88201513.3 has a simple structure, but its gripping force is small, which greatly limits its own functions.

And for those equipment with complex structure and difficult to turn over, such as large box parts or the inside of the machine tool with sealed structure, it is very difficult to clean up the metal shavings adhered to the dirt of the machine tool oil and in the narrow space.

Detailed ways

Embodiment of the utility model is described in detail below in conjunction with accompanying drawing:

Referring to Fig. 1 , Fig. 2 and Fig. 3, a kind of feedback type manual gripper is shown, which comprises a shaping coil 1, which is connected to the handle 14 at one end of the shaping coil 1 through a fastening body 4, and connected to the said shaping coil 1 through a connecting body 19. The claw fixing block 21 at the other end of the shaped snake tube 1 is passed through the drawing wire 20 in the shaped snake tube 1, the connecting body 19 and the claw fixing block 21; the claw fixing block 21 is rotatably connected with two opposite The provided micro-manipulator claws 3 are connected between the two micro-manipulator claws 3 to maintain the two in the open state of the reset part - spring 23; the handle 14 is provided with a chute 16, which slides in the chute 16 A slider 15 is provided, one end of the drawing wire 20 is connected to the slider 15 , and the other end is connected to two micro-manipulator claws 3 through a pull rod 22 .

Described handle 14 is connected to control box 7 by lead wire 13, and camera 2 is arranged on described paw fixed piece 21, and described control box 7 is provided with and is connected with camera 2, is used for displaying the image captured by camera 2. monitor8. The control box 7 has a camera switch 9 for turning on or off the camera 2 and a display switch 10 for turning on or off the display 8 . The control box 7 has a rechargeable battery pack as a power source, and the control box 7 has a charging port 11 and a power switch 12 . The control box 7 also has a handle 6 which is convenient to hold.

There is also a power supply in the handle 14, and a plurality of LED lamps 5 are arranged around the shaped snake tube 1 on the handle 14. There is an LED light switch 28 on the control loop between the power supply on the handle 14 and the LED lamps 5. The light switch 28 is disposed on the handle 14 .

The above-mentioned gripper is suitable for removing iron filings in complex cavities and holes in metal processing and for gripping objects in narrow spaces in production and life, and can also be used for the removal and gripping of other waste chips. The specific use method is as follows: put the shaped coil into a narrow space or a complex shape and cavity hole, choose whether to turn on the power switch 12 according to the use conditions, turn on the display switch 10, the camera switch 9, and observe the micro-manipulator claw through the display 3 location and status. For targets with different distances from the micro-manipulator claws 3, the shape of the shaping coil 1 can be adjusted to make the micro-manipulator claws 3 approach the target. After the adjustment state is completed, through the movement of the slider 15, the manipulator 3 closes the clamping target. The right hand and the left hand cooperate to take out the stereotyped snake tube. When the micro-manipulator claw 3 and the clamped object are taken out, release the slider 15. Under the action of the spring 23, the micro-manipulator claw 3 opens, and the object falls. It has realized the clamping work of objects in complex cavity holes and narrow spaces. If there is no sufficient natural light in the above process operation, then control with the LED switch 28 of the handle 14, and the handle 14 contains a power supply, that is, turn on the LED light 5 to provide sufficient light to adapt to a dark environment; as an industrial endoscopic instrument, it is used for parts box machinery During equipment inspection, the handle 14 can be connected to the interface of the control box 7 with a wire 13, turn on the power switch 12, the display switch 10 and the camera switch 9, and only keep the camera 2 and the display 8 working, and the rest of the operation methods are the same as the above folder The method of taking metal chips can also operate the slide block 15 while maintaining the observation of the metal chips cleaning situation, which also has very strong practicability because it can ensure 360-degree omnidirectional observation in the space.
