Description

Technical Field

[0001] The utility model belongs to the field of gear processing, and in particular relates to a gear surface oil removal device. Background Art

[0002] During the gear production process, cutting oil or lubricating oil is used in conjunction with cutting and grinding. After the gear processing is completed, the oil stains on the gear surface need to be removed. In the prior art, the gears are usually soaked in an alkaline solvent for a period of time and then brushed. The soaking in the alkaline solvent can decompose the oil stains and facilitate subsequent brushing. When the gears are soaked in batches, multiple gears are usually piled in the soaking pool, and the contact effect between the contact surfaces of the stacked multiple gears and the contact surfaces between the gears and the inner wall of the soaking pool and the alkaline solvent will be affected, which will in turn affect the subsequent brushing of the gears, resulting in the degreasing effect being affected. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a gear surface degreasing device to solve the problem that the contact effect of the contact surface of multiple stacked gears and the contact surface between the gear and the inner wall of the immersion tank will be affected by the alkaline solvent.

[0004] According to the embodiment of the utility model, the utility model adopts the following technical solution:

[0005] A gear surface deoiling device comprises an oil removal tank, a hanging basket assembly for placing gears, and a driving assembly for driving the hanging basket assembly to move, the hanging basket assembly comprises a hanging rod and a plurality of supporting grates arranged axially along the hanging rod, the supporting grates comprise an inner supporting ring, an outer supporting ring, and a plurality of supporting rods fixed between the inner supporting ring and the outer supporting ring, and fixing rods are fixed between the outer supporting rings of the multi-layer supporting grates; an upper connecting member and a lower connecting member are installed on the hanging rod, the hanging rod is used to pass through the inner supporting ring, the upper connecting member is used to connect to the inner supporting ring of the supporting grate located at the uppermost layer, and the lower connecting member is used to connect to the inner supporting ring of the supporting grate located at the lowermost layer; the driving assembly comprises a rotatable rotating shaft and a connecting rod fixed to the outer wall of the rotating shaft, the axes of the connecting rod and the rotating shaft are perpendicular to each other, and the connecting rod and the hanging rod are detachably connected.

[0006] Compared with the prior art, the utility model has the following beneficial effects:

[0007] In this solution, gears are placed through supporting grates, and multiple layers of supporting grates can be used to place multiple gears, reducing the contact surface between the stacked gears. The contact area between the gear surface and the supporting grate is reduced by setting the supporting grates, and only the supporting rods, supporting rings and gears have a certain contact.

[0008] In addition, the rotation of the shaft drives the connecting rod to swing in the de-oiling tank, and then drives the hanging basket assembly to swing in the de-oiling tank. During the swinging process, the gear located on the supporting grate is affected by its own gravity and the buoyancy of the alkaline solvent in the de-oiling tank, which will produce a certain movement on the supporting grate, thereby changing the contact point between the gear and the supporting grate, and to a certain extent avoiding the problem that the contact position between the gear and the supporting rod is fixed and cannot be fully contacted with the alkaline solvent. And through the movement of the hanging basket assembly, the gear moves relative to the alkaline solvent, forming an effect of the alkaline solvent flowing relative to the gear, which is more convenient to decompose the oil stains on the surface of the gear and leave them in the alkaline solvent.

[0009] Furthermore, a first safety hook is fixed to the end of the connecting rod, and a hanging ring for hanging on the first safety hook is fixed to the hanging rod.

[0010] Furthermore, the support rod is hollow and has a plurality of air outlets. It also includes a ventilation pipe and a connecting pipe connecting the vertically adjacent support rods. The ventilation pipe is connected to the uppermost support rod and is used to introduce gas into the support rod.

[0011] Furthermore, the air outlet opening faces upward.

[0012] Furthermore, the lower connecting member includes a plurality of bottom rods hinged on the hanging rod along the circumference of the hanging rod, and a second safety hook for connecting with the inner supporting ring is installed on the bottom rod.

[0013] Furthermore, the upper connecting member includes a mounting ring slidably connected to the hanging rod along the axial direction of the hanging rod and a plurality of third safety hooks fixed on the mounting ring along the circumference of the mounting ring, and the third safety hooks are used to connect with the inner support ring.

[0014] Furthermore, the fixed rods include two rods radially arranged along the outer support ring, and also include a movable rod connected between the outer support rings of the multi-layer support grate. The movable rods are also provided with two rods and are respectively located on both sides of the two fixed rods. The movable rods are slidably connected to the outer support ring.

[0015] Furthermore, a connecting ring is fixed on one of the outer support rings, and a fourth safety hook for connecting with the connecting ring is fixed on the movable rod. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The utility model is further described in detail below with reference to the accompanying drawings, and specific implementation methods are given.

[0021] like Figure 1 As shown, the gear surface degreasing device includes a degreasing tank, a hanging basket assembly for placing the gear, and a driving assembly for driving the hanging basket assembly to move. The hanging basket assembly includes a hanging rod 5 and a plurality of supporting grates 9 arranged axially along the hanging rod 5. The supporting grates 9 include an inner supporting ring 8, an outer supporting ring 6, and a plurality of supporting rods 7 fixed between the inner supporting ring 8 and the outer supporting ring 6. In order to reduce the contact area between the gear and the supporting grates 9, in this embodiment, the supporting rods 7 of each supporting grate 9 are set to be three, and the three supporting rods 7 are evenly distributed along the circumference of the inner supporting ring 8, which can support the gear and minimize the contact area between the gear and the supporting grate 9. A fixing rod 10 is fixed between the outer supporting rings 6 of the multi-layer supporting grates 9, and the multi-layer supporting grates 9 are connected by the fixing rod 10.

[0022] An upper connecting member and a lower connecting member are installed on the hanging rod 5. The hanging rod 5 is used to pass through the inner support ring 8 of the multi-layer support grate 9, so that the hanging rod 5 can drive the multi-layer support grate 9 to move. The upper connecting member is used to connect with the inner support ring 8 of the support grate 9 located at the uppermost layer, and the lower connecting member is used to connect with the inner support ring 8 of the support grate 9 located at the lowermost layer. In this embodiment, the upper connecting member includes a bolt for connecting the hanging rod 5 with the inner support ring 8 of the support grate 9 located at the uppermost layer, and the lower connecting member includes a bolt for connecting the hanging rod 5 with the inner support ring 8 of the support grate 9 located at the lowermost layer, that is, the hanging rod 5 and the uppermost and lowermost layers of the support grate 9 are bolted to realize the connection between the hanging rod 5 and the support grate 9, so that the hanging rod 5 drives the multi-layer support grate 9 to move.

[0023] The driving assembly includes a rotating shaft 1 that is rotatably arranged, a connecting rod 2 fixed to the outer wall of the rotating shaft 1, and a motor for driving the rotating shaft 1 to rotate. The axes of the connecting rod 2 and the rotating shaft 1 are perpendicular to each other, and the connecting rod 2 can be driven to swing by rotating the rotating shaft 1. The connecting rod 2 and the hanging rod 5 are detachably connected. Specifically, in this embodiment, a first safety hook 3 is fixed to the end of the connecting rod 2, and a hanging ring 4 for hanging on the first safety hook 3 is fixed to the hanging rod 5. By directly hanging the hanging ring 4 on the first safety hook 3, the connection between the hanging rod 5 and the connecting rod 2 is realized, and the operation is convenient. The first safety hook 3 can be a conventional safety hook in the prior art.

[0024] When in use, an alkaline solvent is injected into the oil removal tank, and multiple gears are placed on the multi-layer support grate 9, and the center holes of the gears are aligned with the inner support ring 8 of the support grate 9, and then the hanging rod 5 passes through the multi-layer inner support ring 8 and the center holes of the multiple gears. The hanging rod 5 can limit the multiple gears to a certain extent to avoid excessive movement of the gears on the support grate 9 when the hanging basket assembly moves, resulting in collision. Then, after connecting the hanging rod 5 to the uppermost and lowermost support grates 9, the hanging rod 5 is hung on the connecting rod 2.

[0025] The drive shaft 1 rotates, and the shaft 1 drives the connecting rod 2 to swing. Since the hanging rod 5 is only hung on the connecting rod 2, the hanging rod 5 can always maintain a vertical state. During the swinging of the connecting rod 2, the hanging rod 5 moves with the connecting rod 2, and the movement trajectory is arc-shaped. Then, when the supporting grate 9 moves accordingly, there is a dual movement in the left and right directions and the up and down directions. During this process, the gear located on the supporting grate 9 is affected by its own gravity and the buoyancy of the alkaline solvent in the de-oiling tank, which will produce a certain movement on the supporting grate 9, so that the contact position between the gear and the support rod 7 and the inner support ring 8 is not fixed, thereby avoiding to a certain extent the problem that the contact position between the gear and the support rod 7 cannot contact the alkaline solvent.

[0026] In another embodiment of the present invention, Figure 3 As shown, in order to better contact the bottom surface of the gear with the alkaline solvent in the oil removal tank, in this embodiment, a vent pipe 20 and a connecting pipe 21 connected between the vertically adjacent support rods 7 are also included. The support rods 7 are hollow, and a plurality of air outlets 19 are opened on the support rods 7. The openings of the air outlets 19 face upward, and the vent pipe 20 is connected to the support rods 7 on the uppermost layer and is used to pass gas into the support rods 7. In the actual design process, the connecting pipe 21 uses a flexible hose, and the length of the connecting pipe 21 is greater than the spacing between adjacent support grates 9, so that the position of the connecting pipe 21 can be adjusted so that the gear is placed on the support grates 9 on the same layer through the space between two adjacent connecting pipes 21 on the support grates 9 on that layer.

[0027] During specific use, gas is introduced into the ventilation pipe 20, and the gas enters the support rods 7 of the lower layer from the uppermost support rod 7 through the connecting pipe 21 in sequence. The gas entering the support rod 7 can be discharged from the air outlet 19. On the one hand, the discharged gas forms bubbles in the alkaline solvent, and the oil stains on the surface of the gear are better decomposed through the movement of the bubbles; on the other hand, the opening of the air outlet 19 faces upward, and the air pressure can generate an upward thrust on the gear located on the support rod 7, so that a gap is generated between the gear and the support rod 7, which makes it easier for the gear to move relative to the support rod 7 during the movement of the hanging basket assembly.

[0028] In another embodiment of the utility model, in order to facilitate the connection between the hanging rod 5 and the supporting grate 9, the designs of the upper connecting member and the lower connecting member are different. In this embodiment, the lower connecting member includes a plurality of bottom rods 17 hinged on the hanging rod 5 along the circumference of the hanging rod 5, and a second safety hook 18 for connecting with the inner support ring 8 is installed on the bottom rod 17. The bottom rod 17 is hinged on the hanging rod 5, which facilitates the bottom rod 17 to be inserted into the multiple layers of inner support rings 8 with the hanging rod 5. When the hanging rod 5 passes through the inner support ring 8 of the lowest layer, the bottom rod 17 is rotated, and the second safety hook 18 is connected to the inner support ring 8 of the lowest layer, which makes the operation more convenient.

[0029] The upper connecting member includes a mounting ring 14 slidably connected to the hanging rod 5 along the axial direction of the hanging rod 5 and a plurality of third safety hooks 16 fixed to the mounting ring 14 along the circumferential direction of the mounting ring 14. The third safety hooks 16 are used to connect with the inner support ring 8. By sliding the mounting ring 14, the mounting ring 14 can be located at the uppermost inner support ring 8, which is suitable for the design of support grates 9 with different numbers of layers. Then, the third safety hooks 16 are connected to the uppermost inner support ring 8, which is more convenient to operate. The second safety hooks 18 and the third safety hooks 16 can both be conventional safety hooks in the prior art.

[0030] In another embodiment of the utility model, the fixed rod 10 includes two rods radially arranged along the outer support ring 6, and also includes a movable rod 11 connected between the outer support rings 6 of the multi-layer support grate 9. The movable rod 11 is also provided with two rods and is respectively located on both sides of the two fixed rods 10. The movable rod 11 is slidably connected to the outer support ring 6. Through the design of the fixed rod 10 and the movable rod 11, when the hanging rod 5 has not been installed, a certain limiting effect can be exerted on the gear on the support grate 9. The setting of the movable rod 11 can facilitate the placement of the gear on the support grate 9 by sliding the movable rod 11.

[0031] In addition, if there is no center hole on the gear, the hanging rod 5 can be directly connected to the topmost inner support ring 8 without inserting the hanging rod 5 into the multi-layer support grate 9. At this time, the gear is completely limited by the fixed rod 10 and the movable rod 11 to prevent the gear from falling from the support grate 9.

[0032] Combination Figure 2 As shown, a connecting ring 12 is fixed on one layer of the outer support ring 6, and a fourth safety hook 13 for connecting with the connecting ring 12 is fixed on the movable rod 11. The fourth safety 13 can be a conventional safety hook in the prior art. Through the connection between the fourth safety hook 13 and the connecting ring 12, after the movable rod 11 slides to a specified position, the movable rod 11 can be limited to prevent the movable rod 11 from sliding by itself during the movement of the supporting grate 9.
