DETAILED DESCRIPTION

[0041] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with embodiments.

[0042] It should be noted that, unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as generally understood by those skilled in the art to which the present application belongs.

[0043] Please refer to Figures 1-13 The present application provides the following technical solutions:

[0044] Embodiment one is to solve the problem that the operator needs to manually hold the speed reducer shell 11 after lifting it with a lifting appliance, so that the flushing surface faces himself, and then the flushing operation can be performed.

[0045] The embodiment comprises a machine tool 1 and a first workbench 2 arranged in the machine tool 1 and used for carrying and processing a reducer shell; the reducer shell processing center further comprises a traction fixing unit 3 and an inclined flushing unit 4; the reducer shell 11 is provided with four to-be-flushed surfaces A, B, C and D, the surfaces A and B are located on one side of the reducer shell 11, the surfaces C and D are located on the other side, and the two sides are oppositely arranged. Each surface is a circular cavity surface, an inner ring groove 112 is arranged in the cavity, and a chip removal chamber E for removing chips is arranged in the middle of the reducer shell 11; the traction fixing unit 3 is arranged beside the first workbench 2; the traction fixing unit 3 comprises a second workbench 31, a rotating bearing part 32, a first limiting part 33 and a pushing part 34; the second workbench 31 is arranged beside the first workbench 2; the rotating bearing part 32 is rotatably arranged on the second workbench 31; a pair of first limiting parts 33 are respectively arranged on the top of the rotating bearing part 32; and the pushing part 34 is slidably arranged on the rotating bearing part 32; the inclined flushing unit 4 is arranged on the second workbench 31, and the inclined flushing unit 4 is used for performing flushing operation on the four to-be-flushed surfaces A, B, C and D of the reducer shell 11.

[0046] In the prior art, after the operator hoists the reducer shell 11 by using the lifting appliance, the operator must manually hold and rotate the shell to adjust each to-be-flushed surface to face the operator, and then the operator needs to hold the spray gun and extend it into the cavity of the shell to rotate and flush the cavity of the shell.

[0047] In the embodiment, after the operator hoists the reducer shell 11 by using the lifting appliance, the operator moves the reducer shell 11 to the top of the rotating bearing part 32 and places the reducer shell 11 between the pair of first limiting parts 33, and then the operator operates the lifting appliance to lower the reducer shell 11, so that the two sides of the non-processing surface of the reducer shell 11 respectively abut against the end faces of the first limiting parts 33. The pair of first limiting parts 33 are made of rubber, and after the bottom of the reducer shell 11 and the chip removal chamber E contact the rotating bearing part 32, the pushing part 34 is started to abut and clamp the reducer shell 11. At this time, the reducer shell 11 is clamped by the first limiting parts 33 and the pushing part 34.

[0048] After clamping, the chip removal chamber E corresponds to the liquid discharge port on the top of the rotating bearing part 32, so that the hoisted reducer shell 11 is quickly and stably clamped and placed on the top of the rotating bearing part 32, and the clamping and fixing of the reducer shell 11 are realized. After clamping, the inclined flushing unit 4 is used for controlling the inclination of the rotating bearing part 32, and cooperates with the flushing unit to complete the clamping, inclination control and rapid cleaning of the reducer shell 11. The problem that the operator needs to hold the reducer shell 11 before and after flushing is solved, the reducer shell 11 is quickly and stably clamped, the flushing posture is flexibly adjusted, and the high-efficiency and rapid cleaning effect is realized in cooperation with the flushing unit.

[0049] Reference is made to Figure 5 and Figure 6The top of the rotating bearing part 32 is provided with a plurality of waste chip discharge ports, and the waste chip discharge ports are arranged along the outer diameter of the rotating bearing part 32. When the reducer shell 11 is respectively contacted with the first limiting part 33 and the pushing part 34, the chip discharge chamber E can correspond to the position of the waste chip discharge port.

[0050] Referring to Figure 6 The traction fixing unit 3 further comprises a first telescopic cylinder 35, a mounting part 36 and rotating rollers 37. The first telescopic cylinder 35 is arranged at the top of the rotating bearing part 32, and the output end of the first telescopic cylinder 35 is connected with the input end of the pushing part 34. When the first telescopic cylinder 35 is started, the pushing part 34 can be driven to be in a moving state. The mounting part 36 is arranged on the side away from the pushing part 34, and the mounting part 36 is located at the top of the rotating bearing part 32. The rotating rollers 37 are arranged in a plurality of numbers and are respectively arranged to rotate on the mounting part 36. The mounting part 36 is provided with a cavity for mounting the rotating rollers 37, and the rotating rollers 37 are arranged in an inclined manner. When the reducer shell 11 is lowered, the reducer shell 11 can be contacted with the rotating rollers 37 and is in a lowered moving state.

[0051] In the embodiment, the first limiting part 33 is a non-machining surface of the reducer shell 11, and does not block the A, B, C and D surfaces of the reducer shell 11. When the reducer shell 11 is lowered, the non-machining surface is contacted with the outside of the rotating rollers 37. During the contacting process, the rotating rollers 37 are synchronously rotated, and because the rotating rollers 37 are arranged in an inclined manner, the reducer shell 11 is sequentially contacted with the inclined rotating rollers 37 and is rotated when being lowered, and is gradually adjusted to be in a flat state during the lowering process. The contacting stability of the reducer shell 11 with the first limiting part 33 during the lowering process is improved, so that the lowering process of the reducer shell 11 can be stably guided by the mounting part 36 and the rotating rollers 37, and the contacting positioning and clamping of the non-machining surface of the reducer shell 11 with the first limiting part 33 are accelerated. After the contacting and positioning, the first telescopic cylinder 35 is started to drive the pushing part 34 to clamp the placed reducer shell 11, so that the non-machining surface of the reducer shell 11 is clamped and fixed.

[0052] In the embodiment, the first limiting part 33 is a non-machining surface of the reducer shell 11, and does not block the A, B, C and D surfaces of the reducer shell 11. When the reducer shell 11 is lowered, the non-machining surface is contacted with the outside of the rotating rollers 37. During the contacting process, the rotating rollers 37 are synchronously rotated, and because the rotating rollers 37 are arranged in an inclined manner, the reducer shell 11 is sequentially contacted with the inclined rotating rollers 37 and is rotated when being lowered, and is gradually adjusted to be in a flat state during the lowering process. The contacting stability of the reducer shell 11 with the first limiting part 33 during the lowering process is improved, so that the lowering process of the reducer shell 11 can be stably guided by the mounting part 36 and the rotating rollers 37, and the contacting positioning and clamping of the non-machining surface of the reducer shell 11 with the first limiting part 33 are accelerated. After the contacting and positioning, the first telescopic cylinder 35 is started to drive the pushing part 34 to clamp the placed reducer shell 11, so that the non-machining surface of the reducer shell 11 is clamped and fixed.

[0053] Referring to Figure 8 and Figure 9The inclined flushing unit 4 comprises a fixed shaft 41, a first electric push rod 42, a circular rod 43 and a connecting part 44. The fixed shaft 41 is provided on both sides of the rotating bearing part 32 and penetrates the second workbench 31. The first electric push rod 42 is provided on the bottom of the second workbench 31 and is located below the rotating bearing part 32. The circular rod 43 is provided on the output end of the first electric push rod 42. The connecting part 44 is rotatably provided on the top of the circular rod 43 and is rotatably connected to the top of the rotating bearing part 32. When the first electric push rod 42 is started, the circular rod 43 is driven to be in an upward state, and the connecting part 44 is driven to be in an inclined state.

[0054] To ensure the stable inclination of the rotating bearing part 32, the first electric push rod 42 is provided on the bottom of the second workbench 31. When the speed reducer shell 11 is clamped on the top of the rotating bearing part 32 and the A and B surfaces need to be flushed, the first electric push rod 42 below the inclined position of the rotating bearing part 32 is started to drive the circular rod 43 and the connecting part 44 to descend. At this time, the other side of the rotating bearing part 32 is lifted, and the corresponding first electric push rod 42 is started to drive the circular rod 43 and the connecting part 44 to ascend, so that the rotating bearing part 32 can be inclined and oscillated on both sides around the fixed shaft 41, and the inclination of the rotating bearing part 32 is completed. Thus, the subsequent flushing and chip removal of the speed reducer shell 11 are better coordinated.

[0055] In the third embodiment, to solve the problem that when the A and B surfaces of the speed reducer shell 11 are sprayed, the operator needs to spray in sequence, the waste chips on the A and B surfaces are easy to splash to the C and D surfaces, the waste chips and waste liquid on the C and D surfaces are easy to splash back to the A and B surfaces, and after all the waste chips are discharged through the chip removal chamber E, the operator needs to insert the flushing pipe into the chip removal chamber E from bottom to top for further cleaning. In general, the chip removal chamber E does not need to be completely cleaned, but only needs to be cleaned in some dead angle areas. Therefore, the existing technology needs to be repeated multiple times to clean completely, which increases the operation process.

[0056] Referring to Figure 6, the inclined flushing unit 4 comprises two first setting frames 45, each of which is provided with a first inclined frame 46, a first spraying pipe 47, a first rotary nozzle 48 and a rotary air cylinder 49; the two first setting frames 45 are both mounted on the top of the rotary bearing part 32, one of which is towards the A and B faces of the speed reducer housing 11, and the other of which is towards the C and D faces of the speed reducer housing 11; the first inclined frame 46 is rotatably mounted on the top of the first setting frame 45, and both the first setting frame 45 and the first inclined frame 46 are located outside the speed reducer housing 11; the first spraying pipe 47 has a pair of and is slidably arranged on the side of the first inclined frame 46, and the pair of first spraying pipes 47 correspond to the sides of the speed reducer housing 11 respectively; the first rotary nozzle 48 is arranged at the end of the pair of first spraying pipes 47 respectively, and is used for flushing the inner ring groove 112 of the speed reducer housing 11; the rotary air cylinder 49 has a pair of and is mounted on the top of the first setting frame 45 respectively, and the output ends of the pair of rotary air cylinders 49 are connected with the two sides of the bottom of the first inclined frame 46, so that the first inclined frame 46 can be driven to be in an inclined state when the rotary air cylinder 49 is started.

[0057] In the embodiment, the inner ring groove 112 is a machining structure of the output shaft ring surface of the speed reducer housing 11, and is used for mounting the output shaft and the sealing ring after being flushed and dried.

[0058] Referring to Figure 7 In the embodiment, when the dead angle area of the chip removal chamber E needs to be flushed, the rotary bearing part 32 is first adjusted to be inclined towards the A and B faces by the first electric push rod 42, the circular rod 43 and the connecting part 44. The second telescopic air cylinder 491 is started to drive the setting plate 492, the first spraying pipe 47 and the first rotary nozzle 48 to move towards the A and B faces until the first spraying pipe 47 and the first rotary nozzle 48 are towards the dead angle area of the chip removal chamber E. In this state, the rotary air cylinder 49 is started to drive the first inclined frame 46 to be inclined away from the A and B faces, and the first spraying pipe 47 and the first rotary nozzle 48 are towards the dead angle area of the chip removal chamber E, so that the spraying range of the first rotary nozzle 48 can cover the dead angle area of the chip removal chamber E; after moving and being inclined, the first rotary nozzle 48 located on the A face is started while the first rotary nozzle 48 located on the B face is not started, so that the first rotary nozzle 48 located on the A face can be used to spray and clean the dead angle area above the chip removal chamber E. Most of the waste chips and waste liquid after being flushed can be directly discharged through the A face of the speed reducer housing 11 in the inclined state along the preset path; a small amount of waste chips and waste liquid will flow through the B face, so that the waste chips and waste liquid during flushing of the dead angle area of the chip removal chamber E can not pollute the C and D faces which are not flushed, and secondary pollution can be avoided.

[0059] Referring to Figure 8When it is necessary to clean the inner annular grooves 112 on the A and B sides of the reducer housing 11, the rotary cylinder 49 is first started, driving the first tilting frame 46, the first spray pipe 47 and the first rotating nozzle 48 to reset. In this reset state, the inclined surface of the first tilting frame 46 can be parallel to the outer inclined surface of the reducer housing 11 in the tilted state. After the reset, the first spray pipe 47 and the first rotating nozzle 48 move away from the reducer housing 11 until the first spray pipe 47 and the first rotating nozzle 48 move and correspond to the position of the inner annular groove 112.

[0060] When the first spray pipe 47 and the first rotating nozzle 48 move and correspond to the position of the inner ring groove 112, the first rotating nozzle 48 located on the A and B sides of the reducer housing 11 starts and rotates to rinse the inner ring groove 112. Since the rotating bearing part 32 and the A and B sides of the reducer housing 11 are inclined, the waste chips and waste liquid generated during rinsing are directly discharged through the inner ring groove 112 on the A and B sides under the combined action of gravity and water flow impact force. This eliminates the need for the rinsing waste chips and waste liquid to pass through the chip discharge chamber E, preventing waste chips and waste liquid from splashing onto the C and D sides from the source. At the same time, it prevents waste chips and waste liquid from adhering to the chip discharge chamber E, saving the need for secondary cleaning.

[0061] See Figure 9 Similar to the principle of rinsing the inner annular grooves 112 on surfaces A and B of the reducer housing 11 in this example, the rotating bearing part 32 is adjusted to an inclined state towards surfaces C and D by the first electric push rod 42. Then, the first rotating nozzle 48 at surfaces C and D is activated to rotate and rinse the inner annular grooves 112 on surfaces C and D. Waste chips and waste liquid are discharged directly through surfaces C and D in an inclined posture, avoiding splashing onto surfaces A and B and the chip discharge chamber E, thus achieving independent rinsing of the rinsing surfaces of the reducer housing 11.

[0062] See Figure 6 The tilting flushing unit 4 also includes a second telescopic cylinder 491 and a mounting plate 492. The second telescopic cylinder 491 is located on the side of the first tilting frame 46. The mounting plate 492 is located at the output end of the second telescopic cylinder 491, and the side of the mounting plate 492 is fixedly connected to the end face of the first spray pipe 47. When the second telescopic cylinder 491 is activated, it can drive the mounting plate 492, the first spray pipe 47 and the first rotating nozzle 48 to move synchronously, for example, synchronously approaching the reducer housing 11 or synchronously moving away from the reducer housing 11.

[0063] In this embodiment, when the A surface and the B surface of the speed reducer shell 11 are in an inclined state, the second telescopic air cylinder 491 is started to drive the connecting setting plate 492, the first spraying pipe 47 and the first rotating nozzle 48 to move towards the direction close to or away from the A surface and the B surface, so that the first spraying pipe 47 and the first rotating nozzle 48 can move away from the A surface and the B surface, and the cleaning of the dead angle area of the chip removal chamber E is completed. When the C surface and the D surface are cleaned, the C surface and the D surface of the speed reducer shell 11 are in an inclined state, and in this state, the second telescopic air cylinder 491 and the setting plate 492 located on the C surface and the D surface of the speed reducer shell 11 drive the first spraying pipe 47 and the first rotating nozzle 48 to move towards the C surface and the D surface and clean.

[0064] In the prior art, in order to realize the inclined cleaning posture, when the speed reducer shell 11 is hung on the rotating bearing part 32, it will naturally incline due to its own gravity, so that the clamping force is concentrated on the first limiting part 33; and the clamping block of the traditional lifting appliance is difficult to stably clamp the non-machining surface while avoiding the to-be-flushed surface, so that the speed reducer shell 11 is easy to be separated during the inclined cleaning, and the stress of the clamping surface is too high.

[0065] Referring to Figure 6 , the inclined flushing unit 4 further comprises a pushing unit 493 and an abutting block 494; the pushing unit 493 is installed on the setting plate 492; the abutting block 494 is arranged on the pushing unit 493, and when the pushing unit 493 is started, the abutting block 494 can be driven to be in a moving state, and the abutting block 494 is used for abutting against the speed reducer shell 11.

[0066] When the speed reducer shell 11 is in an inclined flushing state, the pushing unit 493 is started at this time and drives the abutting block 494 to be in an abutting state against the non-machining surface of the speed reducer shell 11, so that the speed reducer shell 11 can be stably abutted even in an inclined state, the stable placement of the speed reducer shell 11 in the inclined state is ensured, and the non-machining surface of the speed reducer shell 11 is not damaged, the integrity of the speed reducer shell 11 after cleaning is ensured.

[0067] Referring to Figure 4 , a plurality of slots for passing waste liquid and waste chips are formed in the bottom of the second workbench 31, and the plurality of slots are all cuboid structures.

[0068] In this embodiment, the waste liquid and waste chips after flushing can pass through the slots formed in the bottom of the second workbench 31, so that the waste liquid and waste chips are prevented from accumulating at the bottom of the second workbench 31.
