Description

[0002] Some gears are provided with spline grooves to match with splines, so that the gears can rotate synchronously with the transmission shaft. During the production and heat treatment of the gears, oil extraction is used to improve the hardness and wear resistance of the gears.

At present, some oil removal devices can batch immerse the gears in cleaning liquid, and then drive the gears to rotate through rotating devices, so as to clean the gears by using centrifugal force to remove the oil stains on the surface of the gears. However, the gears will be in fixed contact with the cleaning liquid in a certain range during rotation, which can cause some parts of the gears in the area to be unable to be effectively cleaned, thereby reducing the cleaning effect of the gears, or the gears need to be cleaned twice, which can seriously reduce the cleaning efficiency.

DETAILED DESCRIPTION

[0024] The technical solutions of the present application will be described clearly and completely below with reference to the drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0025] Please refer to Figures 1-6 The present application provides a technical solution: a part surface oil cleaning device for metal heat treatment, comprising a base 1, a containing mechanism 2 is installed on the base 1, the containing mechanism 2 comprises a tank body 21 and a tank cover 22 connected in rotation, a screw lifting mechanism 6 is installed on the inner wall of the bottom of the tank body 21, which comprises a plurality of bearing gears and drives the gears to reciprocatingly and spirally lift, a plurality of brush bars 3 are installed on the inner wall of the tank body 21 to clean the radial surface of the gears, the plurality of brush bars 3 are distributed in a circumferential array, one cleaning mechanism 8 is arranged between the two gears connected in series, the cleaning mechanisms 8 on the upper and lower sides of the gears clean the two axial surfaces of the gears during lifting, and a reciprocating drive assembly 7 is arranged at the bottom of the tank body 21 to drive the screw lifting mechanism 6 to reciprocatingly and spirally lift.

[0026] Further, a drain pipe with a valve is installed at the bottom of the tank body 21 to discharge the cleaning liquid in the tank body 21.

[0027] The screw lifting mechanism 6 comprises a cylinder 61 fixedly installed on the inner wall of the bottom of the tank body 21, a sleeve 62 movably sleeved on the cylinder 61, a plurality of spiral guide grooves 611 distributed in a circumferential array are arranged on the cylinder 61, a spiral guide rib 621 matched with the plurality of spiral guide grooves 611 is fixedly installed on the inner wall of the sleeve 62, and a positioning rod 63 is fixedly installed on the outer wall of the sleeve 62.

[0028] The reciprocating driving assembly 7 comprises two bellows 74 penetrating through the bottom of the tank body 21, the bottom ends of the two bellows 74 are sealingly and fixedly connected together, the top ends of the two bellows 74 are fixedly installed with the same annular block one 73, the annular block one 73 is rotatably sleeved outside the sleeve 62, and the bottom end of the positioning rod 63 is above the annular block one 73, the reciprocating driving assembly 7 further comprises two driving mechanisms 71 installed at the bottom of the tank body 21, the two driving mechanisms 71 are mirror distributed, and the double-shaft motor 72 is arranged between the two driving mechanisms 71.

[0029] The driving mechanism 71 comprises a mounting plate 711 fixedly installed at the bottom of the tank body 21, a half gear 712 rotatably installed on the side of the mounting plate 711 away from the double-shaft motor 72 and a guide rail 713 fixedly installed, a long sliding block 714 is slidingly sleeved on the guide rail 713, a rack 715 matched with the half gear 712 is fixedly installed on the long sliding block 714, the top ends of the long sliding block 714 and the long sliding block 714 extend into the corresponding bellows 74, and the top end of the rack 715 is fixedly connected with the bottom of the annular block one 73, the double-shaft motor 72 is fixedly installed between the two mounting plates 711, the output shafts of the double-shaft motor 72 respectively penetrate through the corresponding mounting plates 711 and are fixedly connected with the centers of the corresponding half gears 712, and the output shafts of the double-shaft motor 72 are rotatably connected with the two mounting plates 711.

[0030] Further, the two racks 715 push the annular block one 73 upwards, which can prevent it from rotating.

[0031] The cleaning mechanism 8 comprises an annular block two 81 movably sleeved outside the double-shaft motor 72, an annular groove 811 is formed in the outer side of the annular block two 81, an annular ring 82 is rotatably installed in the annular groove 811, a plurality of circular rods 83 are circumferentially and arrayed distributed and rotatably installed on the outer side of the annular ring 82, a one-way bearing 84 is arranged at the end of the circular rod 83 away from the annular ring 82, and a brush cylinder 85 is fixedly sleeved on the outer side of the circular rod 83.

[0032] A plurality of positioning pieces matched with the plurality of one-way bearings 84 are fixedly installed on the inner wall of the tank body 21, the plurality of positioning pieces are circumferentially and arrayed distributed, and the positioning piece comprises two positioning strips 4 fixedly installed on the inner wall of the tank body 21, and the spacing between the two positioning strips 4 is greater than the outer diameter of the one-way bearing 84.

[0033] Further, since the spacing between the two positioning strips 4 is greater than the outer diameter of the one-way bearing 84, not only can the one-way bearing 84 avoid rotating synchronously with the sleeve 62, but also when the one-way bearing 84 is subjected to the centrifugal force from the axis of the cylinder 61, the one-way bearing 84 will only contact one of the positioning strips 4 and tightly abut against the positioning strip 4.

[0034] The one-way bearing 84 is provided with an inner ring and an outer ring, and the inner ring of the one-way bearing 84 is fixedly sleeved on the round rod 83 and coaxially arranged with the round rod 83.

[0035] Further, the one-way bearing 84 has the effect of being free to rotate in one direction and being locked in the other direction. When the one-way bearing 84 is in the locked state, it can drive the parts fixed on the inner ring to rotate synchronously. When the one-way bearing 84 is not in the locked state, the inner ring of the one-way bearing 84 is in a relatively static state, and the outer ring can freely rotate in one direction.

[0036] The bristles on the brush cylinder 85 are helical.

[0037] Further, since the bristles of the brush cylinder 85 are helical, they not only have a scraping and cleaning effect during rotation around their own axis, but also have a certain conveying capacity.

[0038] The tank cover 22 is fixedly provided with two symmetrically distributed elastic expansion rods 23, and the piston rod bottom end of the two elastic expansion rods 23 is rotatably provided with the same pressing ring 5.

[0039] Further, when the uppermost cleaning mechanism 8 rotates, the pressing ring 5 will rotate synchronously, and the pressing ring 5 can make the pressing force of the two elastic expansion rods 23 more evenly act on the lower cleaning mechanism 8.

[0040] In this embodiment: when in use, clean cleaning liquid is first injected into the tank body 21, the tank cover 22 is rotated to open, most of the cleaning mechanisms 8 are taken out from the sleeve 62, only one at the bottom is retained in contact with the annular block 173, then the gear is sleeved outside the sleeve 62, and the positioning rod 63 is inserted into the spline groove of the gear, then one cleaning mechanism 8 is sleeved outside the sleeve 62 and above the gear, and the above operation is repeated to make the multiple gears and multiple cleaning mechanisms 8 stacked on the sleeve 62, while ensuring that the number of cleaning mechanisms 8 on the sleeve 62 is always one more than the number of gears.

[0041] When the cleaning mechanism 8 is sleeved on the sleeve 62, the multiple cleaning mechanisms 8 thereon need to be between the two positioning strips 4 of the corresponding positioning member, then the tank cover 22 is rotated to close and locked on the tank body 21, during the closing process of the tank cover 22, the two elastic expansion rods 23 drive the pressing ring 5 to abut against the top of the annular block two 81 of the uppermost cleaning mechanism 8 and generate a pressing force on the annular block two 81 and the multiple cleaning mechanisms 8 and multiple gears below the annular block two 81, and at this time, since the position of the annular block one 73 is unchanged, the pressing of the two elastic expansion rods 23 can make the multiple gears and multiple cleaning mechanisms 8 tightly stacked together;

[0042] Then the ring block 73 can be activated, such as Figure 4 As shown, the annular block 73 rotates and drives the half gears 712 on the two drive mechanisms 71 to rotate clockwise. When the half gear 712 meshes with the rack 715, the rack 715 will rise as the half gear 712 continues to rotate. When the two racks 715 push against the annular block 73 at the same time, the annular block 73 will push the sleeve 62 upward. With the cooperation of multiple spiral guide ribs 621 and spiral guide grooves 611, the sleeve 62 will spirally rotate and rise.

[0043] Due to the cooperation between the positioning rod 63 and the gear spline groove, the gear will spiral upward synchronously with the sleeve 62. During the upward movement of the gear, multiple brush strips 3 will clean the radial surface of the gear. At the same time, the friction between the rising gear and the cleaning fluid will complete the cleaning of the radial surface of the gear.

[0044] During the rotation of the gear around the cylinder 61, the friction between the gear axial surface and the cleaning fluid can perform preliminary cleaning of the gear. During the synchronous rise of the cleaning mechanism 8 and the gear, due to the limitation of multiple positioning parts, multiple rods 83 will move vertically upward. Since the brush cylinder 85 does not rotate synchronously with the gear, during the spiral rise of the gear, the brush cylinder 85 will scrape the axial surface of the adjacent gear, thereby completing the secondary cleaning of the gear axial surface. Furthermore, since the one-way bearing 84 abuts against one of the positioning strips 4, it will rotate during the rise of the one-way bearing 84 and drive the rods 83 and the brush cylinder 85 to rotate around their own axis. Since the bristles on the brush cylinder 85 are spiral, during the rotation of the brush cylinder 85, the dirt scraped off the gear can be transported away from the center of the gear, so that the oil will not accumulate on the gear.

[0045] After the half gear 712 separates from the rack 715, under the gravity of multiple gears and multiple cleaning mechanisms 8, the sleeve 62 will spiral downward. Unlike the above steps, since the one-way bearing 84 is free to rotate in one direction, it will rotate on its own during the downward movement without driving the round rod 83 to rotate. Therefore, during the spiral descent of the gear, the brush sleeve 85 only plays the role of cleaning the axial surface of the gear.

[0046] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
