DETAILED DESCRIPTION

[0029] The following will be described in detail with reference to the accompanying drawings Figures 1-4 The application is further described in detail.

[0030] The embodiment of the application discloses a half shaft gear inner spline quenching device. Referring to Figure 1 and Figure 2 The half shaft gear inner spline quenching device comprises a working frame 10, a moving plate 20, a storage assembly 40, a heating coil 511 and a water tank 60. The moving plate 20 is slidably connected to the working frame 10 through a moving assembly 30, so that the moving plate 20 can be flexibly moved on the working frame 10, facilitating operation at different positions, and achieving the effect of transferring the half shaft gear between different processes. This is because the movement of the moving plate 20 can drive the half shaft gear placed thereon to reach different areas such as heating and cooling. The moving plate 20 is provided with a containing groove 21 for inserting a gear, and the storage assembly 40 is arranged on the working frame 10 and can be aligned with the containing groove 21. The storage assembly 40 can feed and discharge the gear in the containing groove 21, so that the feeding and discharging operation of the half shaft gear is more convenient and efficient, and the production efficiency is improved.

[0031] Referring to Figure 1 and Figure 2 The heating coil 511 and the water tank 60 are both arranged on the working frame 10. The working frame 10 is provided with a lifting cylinder 11, the output end of the lifting cylinder 11 is connected with a connecting frame 50, the connecting frame 50 is provided with a rotating motor 51 through bolts, the output end of the rotating motor 51 is connected with the heating coil 511, and the rotating motor 51 is used for driving the heating coil 511 to rotate. The water tank 60 is located below the heating coil 511, the water tank 60 is communicated with a spray head 61, the spray head 61 is fixedly connected with the connecting frame 50, and the spray head 61 can be inserted into the containing groove 21 and spray water in all directions.

[0032] When the accommodating groove 21 reaches the heating coil 511, the lifting cylinder 11 is started to drive the connecting frame 50 to move downwards, thereby driving the heating coil 511 to descend and coaxially insert into the gear, and the rotating motor 51 is started to drive the heating coil 511 to rotate, so that the resistance heating coil 511 generates heat after being electrified and uniformly heats the internal spline of the gear to a certain temperature.

[0033] When the gear heating is completed, the lifting cylinder 11 is started again to drive the connecting frame 50 to move upwards, so that the heating coil 511 is separated from the accommodating groove 21 and drives the nozzle 61 to enter the middle of the gear, and the nozzle 61 is started to cool the internal spline of the gear, thereby ensuring the smooth progress of the quenching process. This is because the heating of the heating coil 511 and the water spraying cooling of the nozzle 61 cooperate to meet the process requirements of the internal spline quenching of the half shaft gear.

[0034] Referring to Figure 1 and Figure 2 , specifically, the moving assembly 30 includes a moving rod 31 and a moving cylinder 32. The moving rod 31 is connected with the moving plate 20, and the moving cylinder 32 is installed on the working stand 10 through bolts. The output end of the moving cylinder 32 is connected with the moving rod 31 and is used to drive the moving rod 31 to translate. When the moving cylinder 32 works, the extension and contraction of the output end drive the moving rod 31 to move, thereby driving the moving plate 20 to slide on the working stand 10.

[0035] Referring to Figure 1 and Figure 2 , specifically, the storage assembly 40 includes a storage ring 41. The storage ring 41 is vertically installed on the working stand 10 and is hollow inside to store gears. The storage ring 41 is provided with a notch 413 on the side wall. The moving plate 20 is adapted to be inserted into the notch 413 and can move in the notch 413. The storage ring 41 is provided with a push plate 71 on the cross section, i.e., the push plate 71 can separate the storage ring 41. The side wall of the storage ring 41 is provided with a sliding groove 414 which is arranged along the circumference of the storage ring 41. The push plate 71 is fixed with a push rod 70 which penetrates through the sliding groove 414 and can move in the sliding groove 414. The end of the push rod 70 away from the push plate 71 is rotationally connected to the center of the storage ring 41.

[0036] When the moving plate 20 moves, the moving rod 31 is always in the notch 413. When the accommodating groove 21 moves to the notch 413, the gears in the accommodating groove 21 fall out of the accommodating groove 21 and fall into the storage ring 41 through the notch 413 to realize the feeding of the gears. The gears in the storage ring 41 fall into the accommodating groove 21 through the notch 413 to realize the feeding of the gears in the accommodating groove 21. Subsequently, when the accommodating groove 21 is misaligned with the notch 413, the moving plate 20 moves to the storage assembly 40 to block the notch 413, so that the gears in the storage assembly 40 cannot fall out of the notch 413.

[0037] With reference to Figure 1 And Figure 3 When the gear in the storage ring 41 is located on the other side of the gap 413, the gear cannot automatically fall by gravity, at this time, the push plate 71 is driven to move in the circumferential direction of the storage ring 41, so that the push plate 71 moves in the storage ring 41, and the push rod 70 moves in the chute 414, the inner wall of the chute 414 is in contact with the push rod 70, which plays a limiting and guiding role, and ensures that the push plate 71 always moves in the diameter direction of the storage ring 41 during movement, and is not easy to tilt, thereby improving the stability of the movement of the push plate 71. The movement of the push plate 71 pushes the gear to move along the track of the storage ring 41, so that the gear reaches the gap 413 for feeding the gear in the containing groove 21.

[0038] With reference to Figure 2 And Figure 3 Specifically, the storage ring 41 includes an upper half ring 411 and a lower half ring 412, the gap 413 is located between the upper half ring 411 and the lower half ring 412, and the push plate 71 is located in the upper half ring 411 and can move in the upper half ring 411. The lower half ring 412 is provided with an air outlet assembly 80 for cleaning the gear in the lower half ring 412. The air outlet assembly 80 includes an air outlet pipe 81 and a gas generator 82, the air outlet pipe 81 is arranged along the track of the lower half ring 412 and located in the middle of the lower half ring 412, a plurality of air outlet holes 811 are formed through the side wall of the air outlet pipe 81, the gas generator 82 is arranged on the side wall of the lower half ring 412, the gas generator 82 is in communication with the air outlet pipe 81, and the gas generator 82 is used for introducing gas into the air outlet pipe 81, and a plurality of slag discharge ports 4121 are formed in the side wall of the lower half ring 412. The gas generator 82 can be an air compressor, which can provide stable gas pressure; or a small air pump, which is suitable for small-scale production.

[0039] When the gear in the containing groove 21 falls into the lower half ring 412, the gear is worn on the air outlet pipe 81, that is, the air outlet pipe 81 is located at the center of the gear, and there is a gap between the air outlet pipe 81 and the inner wall of the gear, so that the air outlet pipe 81 does not contact the internal spline of the gear, which affects the quality of the gear. At this time, the gas generator 82 is started to fill the air outlet pipe 81 with gas, so that the gas flows out of the air outlet hole 811 and blows on the gear, blows off the impurities on the gear through the airflow, realizes the cleaning of the gear, and improves the quality of the gear. The impurities blown off are discharged through the slag discharge port 4121 to avoid accumulation of impurities in the lower half ring 412.

[0040] With reference to Figure 1 And Figure 2Specifically, the accommodating groove 21 is provided with a receiving ring 211, the receiving ring 211 is coaxial with the accommodating groove 21, and the receiving ring 211 is used for supporting the gear. The moving plate 20 is provided with a turnover motor 22, the turnover motor 22 is connected with the receiving ring 211, and is used for driving the receiving ring 211 to turn over. The turnover motor 22 can be a stepping motor, which can accurately control the turning angle; or can be a servo motor, which has higher accuracy and response speed.

[0041] In the initial state, the receiving ring 211 is horizontally arranged at the bottom of the accommodating groove 21. When the gear falls into the accommodating groove 21 and is supported by the receiving ring 211, the gear is stably arranged in the accommodating groove 21. When the gear quenching is completed, the accommodating groove 21 is aligned with the gap 413. At this time, the turnover motor 22 is started to drive the receiving ring 211 to rotate 180°, so that the front and back surfaces of the receiving ring 211 are reversed, thereby making the gear supported by the front surface fall downward, so that the gear automatically falls into the lower half ring 412. During the rotation of the receiving ring 211 in the gap 413, the receiving ring 211 abuts against the gear at the gap 413 of the upper half ring 411, so that the gear cannot fall. When the receiving ring 211 returns to the state of being horizontally arranged at the bottom of the accommodating groove 21, the gear at the outlet of the upper half ring 411 automatically falls into the accommodating groove 21, thereby achieving the feeding of the gears to be machined.

[0042] Referring to Figure 2 and Figure 4 , specifically, a plurality of positioning assemblies 90 are arranged in the sliding groove 414 on the lower half ring 412. The positioning assembly 90 comprises a sliding block 91, a positioning rod 92 and a positioning sleeve 93. The sliding block 91 is inserted into the sliding groove 414 and can move in the sliding groove 414. The sliding block 91 is a T-shaped block, which can ensure stable movement in the sliding groove 414. The positioning rod 92 penetrates the sliding block 91 and is arranged along the diameter direction of the storage ring 41. The positioning sleeve 93 is sleeved on the sliding block 91 and is threadedly connected with the sliding block 91. The end of the positioning rod 92 away from the center of the storage ring 41 is fixed with the positioning sleeve 93. The positioning sleeve 93 rotates to drive the positioning rod 92 to be inserted into the lower half ring 412.

[0043] The positioning rod 92 is inserted into the lower half ring 412 and abuts against the gear. At this time, the positioning sleeve 93 is just moved to abut against the outer side wall of the lower half ring 412, so as to fix the sliding block 91 on the lower half ring 412, so that the position of the sliding block 91 and the position of the positioning rod 92 are fixed, thereby positioning the gear in the lower half ring 412. In this way, the position of the gear in the lower half ring 412 is adjusted, so as to prevent the gears after quenching from being stacked, and the gears are not easy to be pressed.

[0044] The implementation principle of the half shaft gear inner spline quenching equipment is that the half shaft gear inner spline quenching equipment drives the moving plate 20 to slide on the working frame 10 through the moving assembly 30, the material storage assembly 40 realizes the feeding and discharging of the half shaft gear, the heating coil 511 heats the half shaft gear inner spline in the containing groove 21, and the spray head 61 in the water tank 60 sprays water for cooling and quenching.
