Description

Technical Field

[0001] The invention relates to the technical field of deburring, and in particular to a device for deburring the inner hole of a sleeve-type workpiece and a use method thereof. Background Art

[0002] After the inner hole of the sleeve workpiece is drilled, the hole wall may have some burrs. The appearance of burrs will have a great impact on the surface quality of the hole wall. Therefore, after the inner hole is drilled, the hole wall needs to be deburred.

[0003] In the prior art, regarding the method for deburring the inner hole of a sleeve workpiece, some adopt manual grinding, but it is time-consuming, labor-intensive and has low work efficiency; others adopt a motor to drive a brush rod to rotate, the brush rod extends into the inner hole of the sleeve workpiece, and the motor drives the brush rod to rotate so that the brush on the brush rod can deburr the inner hole wall of the sleeve workpiece. When these devices are operated, the sleeve workpiece is first mounted on the fixture of the deburring device, and then the brush rod is driven to move by a translation device so that the brush rod extends into the inner hole of the sleeve workpiece, and then the motor drives the brush rod to rotate to achieve deburring of the sleeve workpiece. When the brush rod is long, the overall rigidity of the rotation is low, and the brush rod is prone to swinging, which not only affects the deburring effect, but also the brush rod itself is prone to breakage. In addition, for sleeve workpieces with different inner diameters, it is often necessary to replace the brush to meet the use requirements, which is more troublesome.

[0026] It should be noted that the above-mentioned airbag 1 20-5 and airbag 2 20-8 are both made of elastic rubber material. Considering that when grinding sleeve workpieces 26 with different inner diameters, the diameters of airbag 1 20-5 and airbag 2 20-8 after swelling are different, that is, the amount of gas that needs to be rushed into cavity 1 and cavity 2 is different, that is, the degree of squeezing of tension spring 19-6 is also different. In order to facilitate indirect monitoring of the grinding of sleeve workpieces 26 with different inner diameters, airbag 1 20-5 and airbag 2 20-8 are used.

[0029] According to the above-mentioned sleeve-type workpiece inner hole deburring device, its use method comprises the following steps: Step 1, first, start the servo motor 10 to adjust the mounting seat 11 to a suitable position, then place the sleeve workpiece 26 to be deburred on the placement seat 6, adjust the height of the placement seat 6 by rotating the screw 5, and allow the grinding assembly 20 to enter one end of the sleeve assembly, then control the telescopic end of the electric push rod 23 to extend through the controller 29 to press the sleeve workpiece 26; Step 2: Next, the operator sets the number of starts of the servo motor 10, the rotation amplitude of each start, and the time interval between two rotations on the controller 29 according to the length of the sleeve workpiece 26 and the width between the sealing component 1 and the sealing component 2 in the grinding component 20; Step 3, then start the grinding program through the controller 29, the controller 29 closes the solenoid valve 15 and the solenoid valve 2 18-7, and starts the high-pressure fan 13. Under the action of the airflow blown by the high-pressure fan 13, the piston rod 19-4 pushes the piston plate 19-2 to move, and then the pressure sensor 19-5 on the piston plate 19-2 squeezes the tension spring 19-6, and at the same time, the gas in the cylinder 19-1 is discharged from the exhaust port 19-7 and enters the cavity 1 and cavity 2 in the grinding component 20 through the air pipe 19-8, so that the airbag 1 20-5 and the airbag 2 20-8 are bulged and fit with the inner wall of the sleeve workpiece 26, so that a sealed cavity is formed between the airbag 1 20-5, the airbag 2 20-8 and the inner wall of the sleeve workpiece 26; Step 4, when the pressure value measured by the pressure sensor 19-5 reaches the alarm value set by the controller 29, the controller 29 energizes the electromagnet 19-3, so that the electromagnet 19-3 is tightly adsorbed on the inner wall of the sleeve workpiece 26, and then the controller 29 opens the solenoid valve 15 and the solenoid valve 2 18-7, and the sand used for grinding the inner wall of the sleeve workpiece 26 in the shell 18-1 is discharged from the discharge port 18-2 and enters the support tube 14 through the inclined pipe, and then the sand is discharged from the sand outlet 14-2 on the support tube 14 along with the high-pressure airflow, and then the high-pressure airflow carries the sand through the conveying hose 28 and the air inlet joint 20-3 into the connecting tube 20-11, and then is sprayed out from the injection port 20-14 on the T-shell 20-12 to grind the inner wall of the sleeve workpiece 26; Step 5, then, the high-pressure airflow in the sealed cavity is discharged from the air outlet joint 20-19 with the sand, and then enters the cyclone separator 18-5 through the return hose 27, and then the airflow is separated from the sand, and the airflow is discharged from the exhaust hole 18-3, while the sand is discharged from the discharge port 18-2 and enters the support tube 14 again through the inclined tube. After the set time, the controller 29 closes the solenoid valve 15 and the solenoid valve 2 18-7. After the sand flows back into the sand collecting device 18, the controller 29 closes the electromagnet 19-3. Under the action of the tension spring 19-6, the piston plate 19-2 is reset, and at the same time, the airbag 1 20-5 and the airbag 2 20-8 are separated from the inner wall of the sleeve workpiece 26; Step 6: At this time, the servo motor 10 rotates a certain amplitude, and continues to repeat steps 3-5 until the inner wall of the sleeve workpiece 26 is polished.
