Description
Technical Field
The utility model relates to a mechanical equipment specifically indicates a differential mechanism oil blanket blade blows oily device.
Background
At present, in the field of machining of mechanical parts, particularly after a test of a gearbox assembly assembling bench, a great amount of residual gearbox oil can be accumulated at a differential oil seal cutting edge. If the oil is not processed, residual oil is squeezed out when the half shaft assembly is subsequently carried out, the squeezed gearbox oil cannot be completely cleaned due to the limitation of space, structure and the like, and the oil leakage of the gearbox can be caused after sale, so that unnecessary complaints of users are caused.
The common treatment method is to directly wipe off the residual oil by using a non-disturbing cloth, and the like, but the method can clean most of the residual oil but is difficult to clean completely; moreover, the wiping force is difficult to control, and too large force can cause the deformation of the oil seal of the differential gear, too small and can not be cleaned cleanly; meanwhile, new pollution risks are inevitably brought to the oil seal in the wiping process, and the new pollution risks can influence the final sealing performance of the oil seal.
Disclosure of Invention
The utility model aims at providing a differential mechanism oil blanket blade blows oily device, the device can realize thoroughly blowing differential mechanism oil blanket blade residual oil totally and not touch the blade again, and the clearance is high-efficient, simple structure.
In order to achieve the above object, the utility model adopts the following technical scheme: the utility model provides a differential mechanism oil blanket blade blows oily device, includes air blow gun and shower nozzle, the shower nozzle is equipped with the shower nozzle inner chamber, along perpendicular shower nozzle central axis equipartition a plurality of with the communicating fumarole of shower nozzle inner chamber, the end of giving vent to anger of air blow gun with the shower nozzle inner chamber is connected.
Furthermore, a joint is connected between the air blow gun and the nozzle, an air passage for communicating the inner cavity of the nozzle with the air blow gun is arranged in the center of the joint, and the cross section area of the air passage is smaller than that of the inner cavity of the nozzle.
Further, the cross-sectional area of the air passage is smaller than that of the air blow gun.
Furthermore, the joint is in threaded connection with the spray head, and a first sealing ring is connected between the joint and the spray head; the connector is in threaded connection with the air blow gun, and a second sealing ring is connected between the connector and the air blow gun.
Furthermore, the cross-sectional area of the gas injection hole is smaller than that of the inner cavity of the spray head.
Further, the air passage has a hollow cylindrical shape.
The utility model has the advantages that:
one of which, the utility model provides a simple and easy high efficiency, can realize blowing differential mechanism oil blanket blade residual oil totally and not touch the oily device that blows of blade again.
Secondly, because the central axial that connects is cylindrical through-hole, can transmit the compressed air who comes out from the air blow gun to the shower nozzle of locating the air blow gun head, and the shower nozzle inner chamber that shower nozzle and joint end are connected transmits compressed air again to the fumarole along the circumference equipartition, compressed air just jets out with very high pressure to differential mechanism oil blanket blade region from the fumarole, blows to the gearbox after will storing up the gearbox oil atomization at the oil blanket blade inside, thereby realizes sweeping differential mechanism oil blanket blade residual oil totally. The blowing pressure of the blowing gun can be realized by an external control gas circuit.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings, which are not intended to limit the scope of the present invention.
The differential oil seal cutting edge oil blowing device shown in figure 1 comprises an air blow gun 3, a spray head 1 and a connector 2 for communicating the air blow gun 3 with the spray head 1, wherein the spray head 1 is provided with a spray head inner cavity 1.2, four air injection holes 1.1 communicated with the spray head inner cavity 1.2 are uniformly distributed along the central axial direction of the vertical spray head 1, the center of the connector 2 is provided with an air passage 2.1 for communicating the spray head inner cavity 1.2 with the air blow gun 3, and the air outlet end of the air blow gun 3 is communicated with the spray head inner cavity 1.2 through the air passage 2.1. The cross section area of the air passage 2.1 is smaller than the cross section area of the spray head inner cavity 1.2 and is also smaller than the cross section area of the air blow gun 3. The cross section area of the gas injection hole 1.1 is smaller than that of the spray head inner cavity 1.2. A threaded hole is formed in one end of the spray head 1 along the axial center of the long shaft and is connected with an external thread at one end of the joint 2; one end of the air blow gun 3 is connected with an air pipe for compressed air, and the other end of the air blow gun is provided with a threaded hole along the center of the long shaft and is connected with the external thread at the other end of the joint 2. The bottom of the thread at the two ends of the joint 2 is respectively provided with a first sealing ring 4 and a second sealing ring 5 along the axial vertical direction, and the first sealing ring 4 and the second sealing ring 5 are O-shaped rubber sealing rings, so that the sealing effect is realized, and the compressed air is prevented from leaking outwards.
The working process of the oil blowing device for the oil seal cutting edge of the differential mechanism is as follows (as shown in figure 2): respectively installing a first sealing ring 4 and a second sealing ring 5 at the bottoms of the threads at the two ends of the joint 2; connecting and fastening the joint 2 and the sealing ring with the spray head 1 and the air blow gun 3 corresponding threaded holes respectively; the air blow gun 3 is communicated with external compressed air; the spray head 1 extends into the differential oil seal, and is matched and positioned with the inner hole of the differential through the cylindrical outer circle at the front end of the spray head 1 to be close to the differential oil seal; the handle of the air blow gun 3 is started to blow oil by compressed air. Compressed air gets into air gun 3 through air gun 1 central axial one end, reaches shower nozzle 1 along connecting 2 central axial air flue 2.1, and the rethread is along four fumaroles 1.1 blowout to differential mechanism oil blanket blade residual oil storage area of 1 central axial equipartition of vertical shower nozzle, and it is inside to blow into the gearbox after atomizing through the high pressure with the residual oil.
