Description

Technical Field

[0001] The invention relates to the technical field of workpiece cleaning, in particular to a high-pressure multi-surface turntable jet cleaning device with a compensation mechanism. Background Art

[0002] After machining mechanical parts, there will be many burrs. The presence of burrs will scratch the surface of the workpiece and seriously affect the life of the workpiece. At present, all walks of life pay more and more attention to deburring, and the methods of deburring are gradually diversified. Common deburring methods are: manual deburring, chemical deburring, electrolytic deburring, ultrasonic deburring, and high-pressure water deburring. Various burr removal methods have their own application fields and defects. For example, manual deburring is inefficient, has a large subjective factor, and the burr removal is not thorough; ultrasonic deburring can only remove the burrs of bonding strength, and the burrs visible to the naked eye cannot be removed.

[0003] High-pressure water deburring is a common burr removal method. It is low-cost, environmentally friendly, and has high processing efficiency. It can effectively remove burrs from deep holes, cross holes, and blind holes.

[0004] CN102989707 discloses a high-pressure water deburring device, which uses a pressure rod clamp to clamp the workpiece, and then uses high-pressure water sprayed from a nozzle to remove the burrs. However, since the nozzle of the device cannot be automatically replaced, it can only clean one type of hole at a time. When the surface of the part to be cleaned is complex, the nozzle needs to be changed manually, and the processing efficiency is low.

[0005] CN104438172 discloses a turret device that can be used to remove burrs. The turret device is designed with three shafts. The turret drive shaft, the drive shaft and the rotating axis of the turret are coaxially arranged. All three shafts need to rotate, so the structure is complex and has many parts, which will reduce reliability. Each nozzle corresponds to a high-pressure water passage, and a lifting valve is installed in the middle of each high-pressure water passage. When the turret rotates to replace the nozzle, the cam fixed on the bracket will lift the lifting valve on the high-pressure water passage corresponding to the nozzle, the pipeline is connected, and high-pressure water is sprayed from the nozzle. The existence of the valve body not only makes the structure more complicated, but also due to the structure and life of the valve body, it is difficult to ensure that there is no water leakage after a long time of use. Maintenance is required at regular intervals, and replacement is required after long-term use, which increases time and labor costs. Summary of the invention

[0026] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0029] Preferably, the main shaft 9 , the compensating head 7 and the turntable 3 are all provided with hollow channels therein.

[0030] Preferably, a transition pressure surface 12 is provided at the rear end of the main shaft 9 and the front end of the compensation head 7, and the transition pressure surface 12 is used to generate pressure on the contact surface B by using its own water pressure.

[0031] Preferably, the compensating head 7 is also provided with a first O-ring 6 .

[0032] Preferably, a plurality of sliding pins 4 are symmetrically provided at the lower end of the compensating head 7 .

[0033] Preferably, the outer sides of the connection between the compensating head 7 and the main shaft 9 and the end cover 1 are respectively provided with a second O-ring 8 and a third O-ring 10 .

[0034] Preferably, the turntable 3 is a multi-sided table structure with multiple side surfaces, and each side surface is provided with a nozzle 5 . The turntable 3 is fixed on the low-speed shaft of the reducer 2 .

[0035] Preferably, a circular hole is opened in the center of the end cover 1, the lower end of the hollow channel in the inner cavity of the main shaft 9 is connected to the inner hole of the end cover 1, and the upper end of the hollow channel of the main shaft 9 is connected to the lower end surface entrance of the hollow channel of the compensation head 7.

[0036] Preferably, the hollow channel outlet of the compensation head 7 is located on the upper end surface of the compensation head 7 and is connected to the hollow channel inlet on the lower end surface of the turntable 3. The turntable 3 is provided with multiple hollow channels, and the outlet of each channel hole corresponds to each side surface of the turntable 3 and is connected to multiple nozzles 5.

[0037] Preferably, the end cover 1 is fixed to the lower side of the reducer 2 housing, the upper end surface of the end cover 1 is in a concave stepped shape, and the lower end surface of the main shaft 9 is in a stepped shoulder shape and is used to cooperate with the end cover 1.

[0038] The hollow channel of the compensation head is "Z"-shaped, and its entrance is located at the center of the lower end surface. The hollow channel of the turntable is "L"-shaped, and multiple "L"-shaped hollow channels are processed inside. The entrance of each channel hole is connected to the outlet of the compensation head, and the outlet is on each corresponding side and connected to the nozzle;

[0039] When the turntable rotates, the corresponding nozzle rotates accurately to the specified position. The motor is a servo motor, and an optical sensor is installed on the housing of the reducer to ensure the rotation accuracy.

[0040] The number of sides of the turntable can be from a regular triangle to a regular octagon. There are two contact modes for contact surface B: contact surface B1, the size of which is the entire upper end surface of the compensation head, and the contact area is larger than the transition pressure surface; contact surface B2, the size of which is a small boss machined on the upper surface of the compensation head, and its contact area is smaller than the transition pressure surface;

[0041] To prevent water leakage under high pressure, static seals are used between the end cover and the main shaft, and between the main shaft and the compensation head. The contact between the end cover and the main shaft, and between the main shaft and the compensation head is designed as a narrow and long stepped contact end face, and two O-rings are used for sealing respectively.

[0042] Dynamic seals are used on the upper surface of the compensation head and the lower inner surface of the turntable. Since the contact surface B between the compensation head and the turntable rotates relative to each other, a sliding pin is installed between the lower surface of the compensation head and the contact surface of the upper end face of the main shaft, which is fixed only in the circumferential direction. As shown in the enlarged view at point A, the inner diameter of the upper end of the main shaft is slightly larger than the inner diameter of the compensation head. There is a transition surface on the compensation head. When water enters the internal channel of the compensation head from the main shaft through this surface from bottom to top, the water has an upward pressure on the transition surface of the compensation head. This pressure firmly presses the compensation head against the lower inner surface of the turntable. In addition, two O-rings are installed on the contact surface B between the compensation head and the turntable to prevent water leakage under high pressure. When the turntable rotates, the water supply is cut off to rotate the turntable smoothly. In this way, water pressure can be used for both sealing and compensation when the compensation head and turntable are worn. The combined action of the two effectively avoids water leakage under high pressure.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the invention content within the protection scope of the present invention.
