High-pressure multi-surface rotary-table jet cleaning device with compensation mechanism

Abstract

The invention discloses a high-pressure multi-surface rotary-table jet cleaning device with a compensation mechanism. The high-pressure multi-surface rotary-table jet cleaning device with the compensation mechanism comprises a motor, a speed reducer, an end cover, a main shaft, a compensation head, a rotary table and a plurality of nozzles, wherein the output end of the motor is rotatably connected with a high-speed shaft of the speed reducer; the end cover is installed at the front side of a shell body of the speed reducer; one end of the main shaft is connected with the end cover, and the other end of the main shaft is connected with the compensation head; one end of the compensation head makes contact with the rotary table; the rotary table is rotatably connected with a low-speed shaftof the speed reducer; and the plurality of nozzles are formed in the side surface of the rotary table separately. The high-pressure multi-surface rotary-table jet cleaning device with the compensationmechanism has the following beneficial effects: due to the existence of a transition pressure surface, the upper end surface of the compensation head is firmly propped against the lower end surface of the rotary table by utilizing the own water pressure in a machining process, a sealing structure does not need to be additionally arranged, dynamic sealing is formed by utilizing the compensation head, and the compensation head can be jacked forwards by utilizing the own water pressure to form compensation under the condition that the compensation head and the rotary table are abraded, so that the service lives of the rotary table and the compensation head are greatly prolonged, water leakage under a high pressure is avoided, automatic nozzle replacement is achieved, and a simple structure and high working efficiency are achieved.

Description

technical field [0001] The invention relates to the technical field of workpiece cleaning, in particular to a high-pressure multi-surface turntable spray cleaning device with a compensation mechanism. Background technique [0002] After the machining of mechanical parts, there will be a lot of burrs, because the existence 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. The methods are: manual deburring method, chemical deburring method, electrolytic deburring method, ultrasonic deburring method, high pressure water deburring method. Each deburring method has its own application field, and each has its own defects. For example, the efficiency of manual deburring is low, the subjective factors are large, and the deburring is not complete; the ultrasonic deburring can only remove the bonding strength ...

Problems solved by technology

[0004] CN102989707 discloses a high-pressure water deburring equipment. The equipment clamps the workpiece with a pressure rod clamp, and then removes the burrs with high-pressure water sprayed from the nozzle. However, because the nozzle cannot be replaced automatically, the equipment can only clean one type at a time. hole, there is a problem that when the surface of the part to be cleaned is complicated, the nozzle needs to be changed manually, and the processing efficiency is low at this time

[0005] CN104438172 discloses a turret device that can be used to remove burrs. It is designed with three shafts. The turret drive shaft, the drive shaft and the rotation axis of the turret are coaxially arranged. All three shafts need to rotate, so there are many complex parts. It will reduce reliability; each nozzle corresponds to a high-pressure water passage, and a poppet 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 correspond to the high-pressure water passage of the nozzle. The poppet valve is jacked up, the pipeline is connected, and the 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 no water leakage for too long. It takes time to maintain and replace after a long period of use, which increases time and labor costs
