Description

Technical Field

[0001] The invention relates to the field of cleaning technology, and in particular to a fully automatic cleaning device for a workpiece cavity. Background Art

[0002] In the processing of hydraulic cylinder parts, the blank needs to be milled. The processing of the blank often involves the processing of the shape, the processing of the internal cavity, etc.

[0003] At present, the processing of hydraulic cylinder parts is all automated, with a variety of machine tools and robots. The camera on the robot identifies the workpiece, and the gripper cylinder at the end of the robot grabs the workpiece by expanding and pressing it against the internal cavity of the workpiece, and accurately places it into the set position of the machine tool. The spindle in the machine tool selects the tool, and the tool processes the workpiece. During processing, cutting fluid is usually sprayed to lubricate and cool the tool.

[0004] After the milling of the workpiece cavity is completed, a large amount of cutting fluid and iron chips will remain on the inner wall of the cavity. The traditional method of cleaning the iron chips in the workpiece cavity mainly relies on manual operation or semi-automatic equipment, which has the problems of low efficiency and unstable cleaning effect. When the robot grabs the workpiece to the next work section, the camera on the robot needs to take a picture of the workpiece and identify the features. Since the workpiece contains a large amount of cutting fluid and iron chips, it is easy to cause inaccurate camera recognition and positioning deviation. When the robot grabs the workpiece, the clamping cylinder at the end of the robot opens the clamping jaws and presses it against the inner wall of the workpiece cavity. If there are iron chips, it will affect the accuracy of the clamping position and cause pressure damage to the surface, especially the functional surface, causing the functional surface to fail to meet the requirements and be scrapped or the surface of the finished product to fail to meet the requirements of the outer tube and become a defective product. If there are iron chips on the surface, it will cause the tap or tool to get stuck during tool processing, or even cause tool collapse, which will have an adverse effect on the workpiece processing and cause the problem of poor product quality.

The first cylinder drives the mounting plate to rise, and the mounting plate drives the jet seat to rise, so that the air blow pipe enters the workpiece cavity.

The second cylinder drives the connecting plate to rise, and the connecting plate drives the telescopic tube to rise. The top of the telescopic tube fits the bottom surface of the workpiece, and the telescopic tube unfolds to wrap the jet seat. The first cylinder then drives the jet seat up and down. At this time, the airflow blown out of the air pipe will cause the cutting fluid and iron chips to splash, which are easy to splash onto the inner wall of the cleaning box. By setting the telescopic tube, the telescopic tube seals the bottom of the workpiece, so that the splashing cutting fluid and iron chips splash onto the inner wall of the telescopic tube, thereby protecting the cleaning box and the external environment of the cleaning box to ensure the cleanliness of the equipment.

[0034] When it is necessary to clean the internal cavity of the workpiece 01, the manipulator grabs the workpiece 01 and places it on the top surfaces of the two placement plates 11. The clamping assembly 5 presses the outer peripheral ring 011 on the top of the workpiece 01 against the top surfaces of the placement plates 11. The driving mechanism 6 drives the swing arm 2 to rotate around the hinge axis, and the other end of the swing arm 2 swings to the bottom of the workpiece 01, so that the air jet seat 4 moves to the bottom of the workpiece 01. The first cylinder 3 drives the mounting plate 31 to rise, and the mounting plate 31 drives the air jet seat 4 to rise, so that the air pipe 45 enters the cavity of the workpiece 01, and the air in the air jet seat 4 is supplied. High-pressure gas is introduced and blown out from the air blowing pipe 45. The air blowing pipe 45 dries the cutting fluid in the workpiece 01 and blows away the iron filings at the same time. The high-pressure airflow flows in the hole of the workpiece 01 to bring the cutting fluid and iron filings out of the workpiece 01, thereby ensuring that the cavity of the workpiece 01 is clean, facilitating accurate identification and stable grasping by the robot arm, making it difficult for the robot arm to deviate from the workpiece 01, reducing the pressure damage to the surface of the workpiece 01, and also solving the problem of tap or cutter jamming or even penetrating cutter jamming due to iron filings, thereby improving the product processing quality.

Since the top of the air blowing pipe 45 is deflected to one side, the air blowing pipe 45 drives the sealing cover 42 and the reducing pipe section 41 to rotate under the push of the gas, and the reducing pipe section 41 rotates on the air intake pipe 431 through the first bearing 44, so that the air blowing pipe 45 can scan the cavity of the workpiece 01, and then cooperate with the first cylinder 3 to drive the jet seat 4 to move up and down, so that the cavity in the workpiece 01 can be cleaned more cleanly.

At this time, the rotation of the stop rod 96 is not blocked, and the connecting ring 81 cannot be driven to rotate.

[0051] A positioning cylinder 14 is installed on both sides of the top of the cleaning box 1. The end of the piston rod of the positioning cylinder 14 is connected to a slide plate 141. The slide plate 141 extends into the cleaning box 1 and slides on the top surface of the placement plate 11. Two push plates 142 are connected to the side of the slide plate 141.

Tube 45 enters into the cavity of workpiece 01, high-pressure gas is supplied into jet seat 4, and high-pressure gas is blown out from air blowing pipe 45. Air blowing pipe 45 dries the cutting fluid in workpiece 01 and blows away iron filings at the same time. High-pressure airflow flows in the hole of workpiece 01 to bring cutting fluid and iron filings out of workpiece 01, thereby ensuring the cleanliness of the cavity of workpiece 01, facilitating accurate identification and stable grasping by the robot, making it difficult for the robot to deviate from workpiece 01. It can also solve problems such as tap or cutter jamming or even penetrating cutter jamming due to iron filings, thereby improving product processing quality.
