Description

Technical Field

[0001] The invention belongs to the technical field of gear processing, and in particular relates to a gear processing device. Background Art

[0002] Gears are mechanical devices that mesh with each other. They are called gears because their outer surfaces resemble teeth. Gears can drive and transmit power, and are common basic units and components in mechanical structures. Gears have a stable structure and diverse functions. Gears and their gear products are important basic parts of mechanical equipment. They are indispensable parts in our production activities. The quality of gears directly affects the operating speed of the machine.

[0003] Some gears need to be polished before actual use. Common gear polishing work is usually done by placing the gears on a workbench. In actual work, it is found that this method has the following shortcomings:

[0004] ① The lighting equipment used for local lighting of gears is usually fixed on the workbench and has a limited lighting range;

[0005] ② During the grinding and processing process, the staff needs to move the grinding and processing equipment around the circumference of the gear many times, which not only makes the grinding and processing work inconvenient, but also requires a larger work space.

[0006] At present, there is a rotary workbench on the market, which has a rotating turntable. The gears are placed on the turntable, and the staff can rotate the gears as needed, thereby improving the convenience of grinding and processing. However, the existing rotary worktable has the following shortcomings:

[0007] ① When the existing gear is placed on the turntable, it is difficult to completely align the center of gravity of the gear with the rotation axis of the turntable by visual inspection alone, especially for gears with irregular shapes. The positional relationship between the center of gravity of the gear and the rotation axis of the turntable is more difficult to confirm, and the gear needs to be moved to align the center of gravity of the gear with the rotation axis of the turntable; however, due to the heavy weight of the gear, it is difficult for the staff to move it, which makes it inconvenient to adjust the position of the center of gravity of the gear on the turntable. When the center of gravity of the turntable deviates far from the rotation axis of the turntable, the rotation axis of the turntable is prone to damage, which affects the service life of the rotary table;

[0008] ② After the gear is polished, it is usually necessary to oil the outer surface of the gear for maintenance. However, the contact surface between the gear and the turntable is not easy to oil, so the gear needs to be lifted first;

[0009] ③ When the gears are oiled for maintenance, excess oil on the gear surface usually gathers at the bottom of the gear. During the subsequent gear transfer process, excess oil drips from the gear surface, resulting in a waste of oil and not being conducive to keeping the working environment clean. Summary of the invention

[0010] In view of the deficiencies in the prior art, an object of the present invention is to provide a gear processing device.

[0011] In order to achieve the above-mentioned invention object, the technical solution adopted by the present invention includes:

The bottom surface of the gear contacts the flexible cushion layer, and the oil in the flexible cushion layer can directly and evenly seep out and automatically adhere to the bottom surface of the gear, so that the bottom surface of the gear can be oiled conveniently without the need for separate operation by the staff.

[0026] Preferably, a raised blocking structure is provided on the support plate, and the area of ​​the support plate located within the blocking structure is used for supporting the gear.

[0027] In the present invention, oil can be filled into the flow channel through the oil port and introduced into the cushion layer through the porous structure arranged in the cushion layer to achieve oiling treatment on the bottom surface of the gear. At the same time, excess oil can be collected and concentrated through the cushion layer and then flow into the flow channel through the porous structure, thereby achieving the effect of collecting excess oil on the outer surface of the gear.

For those skilled in the art, the present invention can be fully understood without the description of these details.

[0051] Example 1

[0052] See also Figure 1 and Figure 3 A gear processing device includes a bracket 11, a working plate 12, a turntable 13, a plane bearing 14 and a supporting plate 15. The working plate 12 is horizontally installed on the bracket 11, and the plane bearing 14 is arranged on the upper surface of the working plate 12. The turntable 13 is rotatably connected to the working plate 12 through the plane bearing 14, so that the turntable 13 can rotate on the working plate 12. The supporting plate 15 is placed on the turntable 13, and the turntable 13 can drive the supporting plate 15 to rotate on the working plate 12 at the same time.

[0053] Specifically, the bracket 11 is provided with four legs 16 , and the four legs 16 are symmetrically distributed below the working plate 12 along the axis of the plane bearing 14 .

[0054] Specifically, the bracket 11 is further provided with a detection unit 17 and a display unit 18. The display unit 18 is located on the side of the working plate 12. The display unit 18 and the detection unit 17 cooperate with each other. The detection unit 17 is symmetrically distributed between the contact surfaces of the four legs 16 and the ground.

[0055] Specifically, there are four groups of detection parts 17 . By providing four groups of detection parts 17 , the four groups of detection parts 17 can detect the pressures respectively exerted on the four legs 16 when they contact the ground.

[0056] Specifically, each leg 16 is provided with a detection point, and the distances between several detection points and the central axis of the plane bearing 14 are equal. Four groups of detection parts 17 are respectively distributed under the four inspection points, and the four groups of detection parts 17 are evenly arranged, so as to obtain more accurate detection data.

[0057] Specifically, a lifting portion is provided on the bracket 11, and the lifting portion includes a support frame 19 and a lifting cylinder 21. The support frame 19 is fixedly connected to the bracket 11 and is located in the middle of the four legs 16. The lifting cylinder 21 is located on the support frame 19 and below the turntable 13. The lifting portion is at least used to lift the rolling portion to move vertically up and down.

[0058] Specifically, a rolling portion is provided on the lifting portion, and the rolling portion includes a mounting plate 22 and a plurality of rolling structures. The rolling portion is transmission-connected to the lifting portion, and the lifting portion is at least used to drive the rolling portion to move in the vertical direction. The mounting plate 22 is fixedly connected to the lifting cylinder 21 and is located at the output end of the lifting cylinder 21. At least three of the plurality of rolling structures are not in the same straight line. The plurality of rolling structures are all arranged on the mounting plate 22. The plurality of rolling structures arranged on the mounting plate 22 can be lifted up at the same time by the lifting cylinder 21, and are used together to lift the supporting plate 15, so that the plurality of rolling portions are always at the same height, and any rolling structure can roll relatively on the supporting plate 15.

[0059] In this embodiment, there are specifically 10 rolling structures, and the 10 rolling structures are evenly arranged in an array above the mounting plate 22, and the heights of the 10 rolling structures are consistent.

[0060] Specifically, each group of rolling structures includes a rolling seat 23 and a ball 24. The rolling seat 23 is arranged on the jacking portion. The end of the rolling seat 23 is provided with a accommodating cavity 25 and an opening. The accommodating cavity 25 is connected to the opening. The accommodating cavity 25 is used to accommodate the ball. The diameter of the opening is smaller than the diameter of the ball. Part of the ball passes through the opening. The ball 24 can roll in the accommodating cavity 25. Several balls 24 jointly lift the support plate 15, so that the support plate 15 can move in position on the several balls 24.

[0061] Specifically, the working plate 12 is provided with a through hole 26, which is located at the center of the working plate 12. The axis of the through hole 26 coincides with the axis of the plane bearing 14, and each set of rolling structures can pass through the through hole 26.

[0062] Specifically, a cushion layer 27 and a blocking ring 28 are provided on the top surface of the support plate 15. The cushion layer 27 is located in the blocking ring 28. The cushion layer 27 has a porous structure. The porous structure on the cushion layer 27 can absorb and collect oil. The blocking ring 28 is at least used to prevent the oil on the support plate 15 from diffusing outward.

[0063] In this embodiment, the cushion layer 27 is specifically a sponge, which is placed on the supporting plate 15 and located in the blocking ring 28 .

[0064] Specifically, the support plate 15 is also provided with an oil port 29, a plurality of flow ports 31 and a flow channel 32. The flow channels 32 are evenly arranged inside the support plate 15. The flow channels 32 can collect the oil flowing in through the flow ports 31, and can also inject the oil into the flow channel 32 through the oil port 29, and then penetrate into the cushion layer 27 through the flow port 31, so as to achieve oiling treatment on the bottom surface of the gear.

[0065] Specifically, a jacking hole 33 is provided on the turntable 13 , the axis of the jacking hole 33 corresponds to the axis of the plane bearing 14 , and multiple groups of rolling structures can pass through the jacking hole 33 to contact the supporting plate 15 .

[0066] When processing the gear, the gear is placed on the supporting plate 15. The supporting plate 15 is placed above the turntable 13. The turntable 13 can rotate through the plane bearing 14, thereby driving the gear placed on the turntable 13 to rotate. When it is necessary to adjust the position and center of gravity of the gear on the supporting plate 15, after the supporting plate 15 contacts the turntable 13, the four groups of detection units 17 simultaneously check the status of the bracket 11, and the detected data is displayed through the display unit 18. When the data of the four groups of detection units 17 are not unified, the position of the supporting plate 15 on the turntable 13 needs to be adjusted until the data of the four groups of detection units 17 are unified, so as to detect whether the center of gravity of the supporting plate 15 coincides with the center of the turntable 13.

[0067] When actually making adjustments, the lifting cylinder 21 arranged on the support frame 19 is started, and the output end of the lifting cylinder 21 pushes the multiple groups of rolling structures arranged on the mounting plate 22 to move upward at the same time, and passes through and then passes through the jacking hole 33, so that the rolling balls 24 arranged on the rolling seats 23 contact the supporting plate 15, and jack up the supporting plate 15, and separate it from the turntable 13 at a certain distance. At the same time, the staff moves the supporting plate 15, and the supporting plate 15 moves on the multiple groups of rolling balls 24 until the center of gravity of the supporting plate 15 after the gear is placed is adjusted to overlap with the center of gravity of the turntable 13. After the adjustment, the output end of the lifting cylinder 21 moves downward, and at the same time drives the supporting plate 15 to move downward so that the supporting plate 15 contacts the turntable 13 again, thereby achieving the purpose of adjusting the center of gravity of the supporting plate 15 where the gear is placed to coincide with the center of gravity of the turntable 13.

[0068] When the gear is placed on the supporting plate 15 and the oil attached to the gear surface is removed, the staff will scrape the oil attached to the gear surface downward and the oil will flow into the cushion layer 27 and be adsorbed by the porous structure. When there is too much oil on the supporting plate 15, the excess oil will be restricted on the supporting plate 15 by the blocking ring 28, so that the oil will not flow onto the working plate 12 and will not dirty the working plate 12. The excess oil can also flow into the flow channel 32 through the flow port 31 for collection, and the oil shell in the flow channel 32 is extracted through the oil port 29, so as to realize the collection of oil and improve the utilization rate of oil.

[0069] When the contact surface between the gear and the cushion layer 27 needs to be oiled, oil is injected into the flow channel 32 through the oil port 29. The oil fills the flow channel 32 and flows into the cushion layer 27 through the flow port 31. The porous structure in the cushion layer 27 absorbs the oil, and the oil will seep out from the surface of the cushion layer 27, which is conducive to the gear surface being evenly contacted with the oil, thereby achieving automatic adhesion of the oil to the contact surface between the gear and the cushion layer 27.

[0070] Example 2

[0071] See also Figure 4 The difference between this embodiment and embodiment 1 is that a plurality of circular holes 34 penetrating the working plate 12 are provided on the working plate 12, and the plurality of circular holes 34 are circularly distributed on the outer side of the bearing, and the 10 groups of rolling structures are also circularly arranged around the center of the lifting cylinder 21 and evenly arranged on the mounting plate 22, and the diameter of the 10 groups of rolling structures is larger than the diameter of the turntable 13, and the diameter of the supporting plate 15 is larger than the diameter of the turntable 13, and the plurality of rolling parts respectively pass through the corresponding circular holes 34 and contact the bottom side edge of the turntable 13, so that the supporting plate 15 can roll on the balls 24 on each group of rolling parts and realize the position adjustment function.

[0072] When it is necessary to adjust the position of the supporting plate 15 on the turntable 13, the lifting cylinder 21 is started, and the lifting cylinder 21 pushes the multiple groups of rolling structures arranged on the mounting plate 22. Each group of rolling structures passes through the corresponding circular holes 34 and contacts the part of the supporting plate 15 extending out of the turntable 13, and pushes the supporting plate 15 to separate from the turntable 13. Then the supporting plate 15 is pushed, and the supporting plate 15 moves on the rolling ball 24. The pressure at the four detection points of the bracket 11 is checked by the detection unit 17, and the pressure on the bracket 11 is monitored in real time through the display unit 18, and adjustment is realized, so that the position of the supporting plate 15 on the turntable 13 can be conveniently adjusted.
