Aiming at the technical problem that gears are prone to dead corners when washing and drying, the first and second inner support mechanisms are staggered and cooperate with the mounting seat to drive the self-switching inner support fixture to flip. During the flipping process, the gear automatically switches between the first and second inner support mechanisms under the action of gravity, realizing automatic switching of the clamping parts, which is convenient for washing and drying without dead corners.

[0024] 2. Rollers are arranged on the side walls of the first inner support plate and the second inner support plate. The rollers allow the gear to be processed to slide along the axial direction of the clamping shell. The anti-slip layer makes it difficult for the gear to be processed to rotate relative to the first inner support plate, thereby ensuring that the self-switching inner support clamp can drive the gear to rotate synchronously. At the same time, when the self-switching inner support clamp is flipped, the gear can slide axially along the self-switching inner support clamp and switch between the first inner support mechanism and the second inner support mechanism.

[0025] 3. The self-switching inner support fixture is driven to rotate by the second rotary drive, and the U-shaped swing tube is used to reciprocate and flush, so that the gears clamped by the self-switching inner support fixture can be flushed in all directions.

[0026] 4. The sliding cleaning bracket makes it easy to fix the gear to be cleaned on the self-switching internal support fixture, which is convenient for loading.

[0027] 5. The lifting mechanism drives the cleaning bracket to move up and down, and the flipping of the self-switching inner support fixture is completed in the ventilation chamber, so that more cleaning brackets can be installed in the cleaning chamber to meet the cleaning and drying needs of large quantities of gears.

[0035] When in use, the air inlet pipe 13 is connected to the ventilation device (not shown in the figure). If oil is used to flush the gear 76, the air outlet pipe 14 is connected to the oil mist recoverer (not shown in the figure). The ventilation device and the oil mist recoverer are both existing technologies and will not be described in detail here. When the gear 76 is flushed and needs to be ventilated and dried, the ventilation device and the oil mist recoverer can be started.

[0036] See also Figure 1-Figure 6, a box door 17 is hinged at the feeding port 11. The length of the ventilation cavity 9 is greater than that of the cleaning cavity 10, reserving enough space for the self-switching inner support fixture 7 to flip. A diagonal guide plate 18 is connected between the bottom wall of the ventilation cavity 9 and the upper wall of the cleaning cavity 10.

[0037] As Figure 1-Figure 6 shown, the lifting mechanism 3 includes a lifting screw 19, a lifting motor 20 and a lifting slide 21.

The inner mounting frame 24 is rotatably arranged between the two groups of middle sliding plates 25. The inner mounting frame 24 is in a rectangular frame configuration. The inner side walls of the outer fixed frame 23 close to the lifting slide 21 are symmetrically provided with limiting plates 27. The inner mounting frame 24 is clamped between the limiting plates 27. The limiting plates 27 can prevent the inner mounting frame 24 from rotating.

[0040] A draw handle 28 is arranged on the side of the inner mounting frame 24 away from the lifting slide 21. The draw handle 28 facilitates the drawing or rotation of the inner mounting frame 24.

[0041] In this embodiment, the draw rail 26 is preferably a damping rail, and the damping rail makes the drawing of the inner mounting frame 24 softer and smoother.

[0042] As Figure 9-14As shown, the self-switching internal support clamp 7 includes a clamping shell 29 and a first internal support mechanism 30 and a second internal support mechanism 31 which are staggered. One end of the clamping shell 29 is rotatably connected to the mounting seat 5. The first internal support mechanism 30 and the second internal support mechanism 31 are arranged in sequence from front to back along the axial direction of the clamping shell 29. A shaft head 32 is rotatably penetrated at the end of the clamping shell 29, and the shaft head 32 is connected to the first internal support mechanism 30 and the second internal support mechanism 31.

[0043] The side wall of the clamping shell 29 is provided with a first hole 33 and a second hole 34 in sequence from front to back along the axial direction. The first holes 33 are distributed in a circular array around the axis of the clamping shell 29, and the second holes 34 are distributed in a circular array around the axis of the clamping shell 29. The first holes 33 and the second holes 34 are staggered. The first inner support mechanism 30 includes a first bidirectional screw 35, a first hinge rod 36 and a first inner support plate 37. The first bidirectional screw 35 is rotatably arranged on the inner wall of one end of the clamping shell 29 close to the mounting seat 5. The first bidirectional screw 35 has threads with opposite screw directions at both ends. The first bidirectional screw 35 is respectively threadedly connected to a first screw seat 38 at both ends. The first hinge rod 36 is symmetrically arranged on one side of the first inner support plate 37 close to the clamping shell 29. One end of the first hinge rod 36 is hingedly connected to the first screw seat 38, and the other end of the first hinge rod 36 passes through the first hole 33 and is hingedly connected to the side wall of the first inner support plate 37 The second inner support mechanism 31 includes a second bidirectional screw 39, a second hinge rod 40 and a second inner support plate 41. The second bidirectional screw 39 is coaxially fixed to the end of the first bidirectional screw 35. Both ends of the second bidirectional screw 39 are provided with threads with opposite screw directions. Both ends of the second bidirectional screw 39 are respectively threadedly connected with a second screw seat 42. The second hinge rod 40 is symmetrically arranged on the side of the second inner support plate 41 close to the clamping shell 29. One end of the second hinge rod 40 is hingedly connected to the second screw seat 42, and the other end of the second hinge rod 40 passes through the second hole 34 and is hingedly connected to the side wall of the second inner support plate 41. The first bidirectional screw 35, the second bidirectional screw 39 and the shaft head 32 are coaxially fixed in sequence from front to back. The shaft head 32 rotates to penetrate the side wall of the clamping shell 29 away from the mounting seat 5 and extends out of the clamping shell 29. By rotating the shaft head 32, the first bidirectional screw 35 and the second bidirectional screw 39 can be driven to rotate synchronously.

[0044] The specific working principle of the self-switching internal support clamp 7 is as follows: screw the shaft head 32, when the shaft head 32 rotates forward, the shaft head 32 rotates to drive the first bidirectional screw 35 and the second bidirectional screw 39 to rotate forward, the first bidirectional screw 35 rotates to drive the first screw seats 38 at both ends to move toward each other, the first screw seat 38 pushes the first internal support plate 37 to move outward and open through the first hinge rod 36, the second bidirectional screw 39 rotates to drive the second screw seats 42 at both ends to move toward each other, the second screw seat 42 pushes the second internal support plate 41 to move outward and open through the second hinge rod 40, the first internal support plate 37 and the second internal support plate 41 move outward and open synchronously, and the gear 76 is internally supported and clamped. The first internal support mechanism 30 and the second internal support mechanism 31 are staggered. When the gear 76 switches from the first internal support mechanism 30 to the second internal support mechanism 31, the clamping position of the gear 76 can be switched, which is convenient for washing and drying without dead angles.

[0045] A side wall of the first inner support plate 37 away from the clamping shell 29 and a side wall of the second inner support plate 41 away from the clamping shell 29 are respectively provided with a plurality of groups of wheel holes 43 arranged in an array along the length direction, and a roller 44 is rotatably arranged in the wheel hole 43, and an anti-skid layer is wrapped on the outer side of the roller 44.

The lifting motor 20 drives the lifting screw 19 to rotate. The lifting screw 19 drives the lifting slide 21 to rise along the lifting screw 19 and the limit slide rail 22. The lifting slide 21 drives the cleaning bracket 4 to move up into the cleaning chamber 10. After the ascent is completed, hold the pull-out handle 28 on the side wall of the cleaning bracket 4 and pull the inner mounting frame 24 outward.

When the middle slide 25 moves to the end of the pull-out slide rail 26, the inner mounting frame 24 is located in the chassis. 1, and then control the first rotary drive 6 through the control panel 71 to drive the mounting seat 5 to rotate 90°, so that the self-switching internal support fixture 7 rotates from a vertical state to a horizontal state, and then the material is loaded. In the initial state, the self-switching internal support fixture 7 is in a retracted state, the gear 76 to be cleaned is inserted into the self-switching internal support fixture 7, and then the shaft head 32 is screwed, and the shaft head 32 rotates to drive the first bidirectional screw 35 and the second bidirectional screw 39 to rotate, and the first bidirectional screw 35 rotates to drive the first screw seats 38 at both ends to move toward each other, and the first screw seat 38 pushes the first internal support plate 37 to move outward through the first hinge 36, and the second bidirectional screw 39 rotates to drive the second screw seats 42 at both ends to move toward each other, and the second screw seats 42 are driven by the second hinge 40 The second inner support plate 41 is pushed to move outward and open, and the first inner support plate 37 and the second inner support plate 41 are moved outward and open synchronously. When the second inner support plate 41 or the first inner support plate 37 is tightly fitted with the inner wall of the shaft hole of the gear 76 and the gear 76 cannot rotate, the shaft head 32 is stopped from rotating, and then the cross-shaped bracket 46 is inserted into the cross-shaped bracket hole 45 and the threaded cap 47 is tightened to fix the cross-shaped bracket 46 to the end of the self-switching inner support fixture 7. At this time, the gear 76 to be cleaned is fixed on the self-switching inner support fixture 7, and each self-switching inner support fixture 7 is installed with a gear 76. When all the self-switching inner support fixtures 7 on the cleaning bracket 4 are installed with gears 76, the first rotary drive 6 is controlled by the control panel 71 to drive the mounting seat 5 to rotate 90°, so that The self-switching inner support fixture 7 rotates from a horizontal state to a vertical state. At this time, the gear 76 automatically slides downward along the self-switching inner support fixture 7 to the bottom end of the self-switching inner support fixture 7 under the action of gravity. The gear 76 at the upper end of the mounting seat 5 is clamped by the first inner support mechanism 30, and the gear 76 at the lower end of the mounting seat 5 is clamped by the second inner support mechanism 31. Then the inner mounting frame 24 is pushed back into the cleaning bracket 4 and inserted between the limit plates 27 for reset. Then the lifting mechanism 3 is controlled by the control panel 71 to drive the cleaning bracket 4 to move down into the cleaning chamber 10.

After cleaning for a period of time, the swing flushing mechanism 12, the second rotary drive 8 and the cleaning pump 68 are controlled to stop working, and then the self-switching inner support fixture 7 on each group of cleaning brackets 4 is flipped in sequence. When flipping, the cleaning bracket 4 is first driven to move up to the ventilation chamber 9 through the lifting mechanism 3, and then After that, the control panel 71 is used to control the first rotary drive 6 to drive the mounting seat 5 to rotate 180°, and the mounting seat 5 drives the self-switching inner support clamp 7 to flip, and the gear 76 also flips accordingly, and the gear 76 slides down along the axis of the self-switching inner support clamp 7 through the roller 44 to switch the clamping position. At the same time, the anti-skid layer on the surface of the roller 44 can make it difficult for the gear 76 to produce circumferential rotation. After the flipping is completed, the cleaning bracket 4 is driven to move down and reset through the lifting mechanism 3, and the above operation is repeated to flip the self-switching inner support clamp 7 on each cleaning bracket 4. After all the flippings are completed, the swing flushing mechanism 12, the second rotary drive 8 and the cleaning pump 68 are started again to continue flushing the gear 76. At this time, the flushing nozzle 66 can flush the first The blocked parts during washing are rinsed to ensure all-round washing without dead angles. After all the rinsing is completed, the cleaning bracket 4 is moved up to the ventilation chamber 9 by the lifting mechanism 3 for ventilation and drying. During the ventilation process, the lifting mechanism 3 can be controlled to move all the cleaning brackets 4 down to the cleaning chamber 10, and then each group of cleaning brackets 4 is moved up to the ventilation chamber 9 in sequence to flip the self-switching inner support clamp 7. After the flipping is completed, the cleaning bracket 4 is moved down to the cleaning chamber 10 again. After all the self-switching inner support clamps 7 are flipped, all the cleaning brackets 4 are moved up to the ventilation chamber 9 by the lifting mechanism 3 to continue ventilation and drying. During the first ventilation, the blocked parts of the gear 76 can be fully exposed, which is convenient for all-round ventilation and drying.
