Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a motor shaft quenching processing device. Background Art

[0002] Quenching is a heat treatment process. The quenching of steel is a heat treatment process in which the steel is heated to a temperature above the critical temperature Ac3 (hypoeutectoid steel) or Ac1 (hypereutectoid steel), kept warm for a period of time to make it fully or partially austenitized, and then rapidly cooled to below Ms (or isothermally near Ms) at a cooling rate greater than the critical cooling rate to undergo martensite (or bainite) transformation. The solid solution treatment of materials such as aluminum alloys, copper alloys, titanium alloys, and tempered glass, or a heat treatment process with a rapid cooling process is usually called quenching. The motor shaft often needs to be quenched during production and processing to improve the strength of the motor shaft. In traditional motor shaft quenching operations, the motor shaft is usually heated manually by hand and then placed in water for cooling to complete the quenching process. However, this quenching method not only increases labor costs, but also poses a high risk to human health due to the extremely high temperature of the heat source and the heated motor shaft.

[0003] Among them, publication number "CN219637255U" discloses "a motor shaft quenching processing device". This quenching processing device provides an idea of ​​​​setting components such as hydraulic cylinders, carrier plates and heating rings to avoid uneven heating and clamping blind spots on the motor shaft, and has high practicality. However, this quenching processing device still has certain shortcomings in actual use. Although this quenching processing device can make the motor shaft evenly heated and reduce the heating blind spots in the heating link through many components, this quenching processing device is easy to complete the partial quenching operation of the motor shaft due to the lack of clamping operation. There are still a large number of motor shafts that only need to be partially quenched during processing, and this quenching processing device still requires manual loading, which greatly increases the labor cost when using this quenching processing device. For this reason, the utility model provides a motor shaft quenching processing device. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a motor shaft quenching processing device, which solves the problems of the prior art quenching processing devices, such as heating blind spots, uneven heating, the need for manual loading, and the difficulty in completing full or partial heating of the motor shaft with one device.

[0005] To achieve the above purpose, the utility model is implemented through the following technical solutions: a motor shaft quenching processing device, including a box body, a feeding assembly for automatic feeding of the motor shaft is fixedly installed on the top of the box body, and a lifting assembly for controlling the lifting of the motor shaft is fixedly installed on the top of the box body, and the lifting assembly includes:

[0006] A lifting cylinder is fixedly installed on the top of the box, the output end of the lifting cylinder extends to the inside of the box through a connecting hole and is fixedly connected to a connecting plate, and a pneumatic clamp for clamping the motor shaft is fixedly installed on the left side of the connecting plate through a fixing plate;

[0007] The feeding assembly includes an inclined material platform fixedly installed on the top of the box body, a storage box for storing the motor shaft is fixedly installed on the right side of the top of the inclined material platform, a propulsion cylinder for pushing the motor shaft is fixedly installed on the left side of the top of the inclined material platform, and an inclined material plate is fixedly installed on the side of the inclined material platform corresponding to the propulsion cylinder.

[0008] Preferably, a heating assembly is fixedly installed on the inner side of the box body, and the heating assembly includes a heating device fixedly installed on the inner wall of the box body, and the heating device is fixedly connected to a heating ring for heating the motor shaft through a heating tube.

[0009] Preferably, a cooling water tank for cooling the motor shaft after heating is slidably connected to the bottom inner side of the box body, and an inclined plate is fixedly installed on the bottom inner side of the cooling water tank.

[0010] Preferably, a slide groove is provided on the inner wall of the box body near the lifting assembly, a slider is slidably connected to the inner side of the slide groove, and a support plate is fixedly connected to the slider near the center of the box body.

[0011] Preferably, a return spring is fixedly installed on the inner side of the slide groove, and the top of the return spring is in contact with the sliding block.

[0012] Preferably, a feed cylinder is fixedly connected to the top of the box body through a mounting hole, and a material guide cylinder is fixedly mounted on the top of the feed cylinder.

[0013] Beneficial Effects

[0014] The utility model provides a motor shaft quenching processing device. Compared with the prior art, it has the following advantages:

[0015] Beneficial effects:

[0016] (1) The motor shaft quenching processing device, through the established lifting component, can drive the connecting plate and the fixed plate to move up and down through the lifting cylinder when the quenching processing device is in use, so that the pneumatic clamp can be moved up and down. Compared with the traditional quenching of the motor shaft, most of the motor shafts are heated by hand. Clamping with a pneumatic clamp can not only effectively ensure work efficiency, but also greatly reduce the risk of manual operation. When facing the need to quench the entire motor shaft or part of it, it can be completed by the lifting component in conjunction with the support plate, which greatly improves the efficiency of the quenching processing device.

[0017] (2) The motor shaft quenching processing device, through the inclined plate, reset spring, slider and support plate, can be used in the quenching processing device. The inclined plate can displace the motor shaft that has been quenched and enters the cooling water tank for cooling for a certain distance, which can not only make the cooling more comprehensive, but also to a certain extent avoid the incomplete cooling caused by the accumulation of the motor shaft in the cooling link due to incomplete cooling. The reset spring, slider and support plate can play a supporting role for the motor shaft that needs to be completely quenched. When the clamped part of the motor shaft is difficult to be completely quenched due to being in the clamped state, the pneumatic clamp can loosen the motor shaft and provide support through the support plate, and then the support plate is pressed down by the connecting plate to complete the overall quenching of the motor shaft. Finally, when the downward pressing distance exceeds the length of the motor shaft, the motor shaft is unloaded, which greatly improves the processing efficiency of the quenching processing device.

[0018] (3) The motor shaft quenching processing device, through the established feeding assembly, can make the quenching processing device, when in use, store a certain amount of motor shafts to be processed through the storage box, and then let the motor shaft roll and move on the inclined material table through the discharge port. When the motor shaft stops moving, the motor shaft is pushed onto the inclined material plate through the push cylinder, and then enters the box body for processing through the guide tube and the feeding tube. Compared with the traditional manual feeding operation method, the feeding assembly can not only greatly improve the automation degree of the quenching processing device, but also greatly reduce the labor cost.

[0028] The feeding assembly 12 includes an inclined material platform 1202 fixedly installed on the top of the box body 1, a storage box 1201 for storing the motor shaft is fixedly installed on the right side of the top of the inclined material platform 1202, a propulsion cylinder 1203 for pushing the motor shaft is fixedly installed on the left side of the top of the inclined material platform 1202, and an inclined material plate 1204 is fixedly installed on the side of the inclined material platform 1202 corresponding to the propulsion cylinder 1203.

[0029] In this embodiment: a heating assembly 2 is fixedly installed inside the box 1, and the heating assembly 2 includes a heating device 201 fixedly installed on the inner wall of the box 1. The heating device 201 is fixedly connected to a heating ring 203 for heating the motor shaft through a heating tube 202.

[0030] Specifically, when in use, the heating device 201 generates a high temperature in the heating ring 203 through the heating tube 202 , thereby heating the motor shaft inside the heating ring 203 .

[0031] In this embodiment, a cooling water tank 3 for cooling the motor shaft after heating is slidably connected to the inner bottom of the box body 1 , and an inclined plate 5 is fixedly installed on the inner bottom of the cooling water tank 3 .

[0032] Specifically, when in use, the motor shaft is heated and then falls into the cooling water tank 3, and the water in the cooling water tank 3 quickly cools the motor shaft to achieve the purpose of quenching. The inclined plate 5 can make the motor shaft that falls into the cooling water tank 3 move an end distance. In this process, not only the cooling effect can be improved, but also the situation that the heat dissipation effect of the motor shaft is poor due to stacking can be avoided to a certain extent.

[0033] In this embodiment, a slide groove 6 is provided on the inner wall of the box body 1 near the lifting assembly 4 , a slider 8 is slidably connected to the inner side of the slide groove 6 , and a support plate 9 is fixedly connected to the slider 8 near the center of the box body 1 .

[0034] Specifically, when in use, the support plate 9 can be lifted and lowered a certain distance inside the slide groove 6 by the slider 8, and then cooperate with the lifting component 4 and the return spring 7 to achieve the support and unloading functions of the motor shaft.

[0036] Specifically, when in use, the return spring 7 can lift the support plate 9 to a certain height through the slider 8, so that the support plate 9 plays a supporting role during the heating process of the motor shaft.

[0037] In this embodiment: a feed cylinder 11 is fixedly connected to the top of the box body 1 through a mounting hole, and a material guide cylinder 10 is fixedly mounted on the top of the feed cylinder 11 .

[0038] Specifically, when in use, the conical shape of the guide cylinder 10 can facilitate the insertion of the motor shaft, and then the motor shaft enters the interior of the box body 1 through the feed cylinder 11 to perform the quenching process.

[0039] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0040] Working principle: During the specific work, the staff will place the quenching processing device at the designated position, and then preset the lifting cylinder 401, pneumatic clamp 404, propulsion cylinder 1203 and heating equipment 201 according to the quenching length of the motor shaft, and then put the motor shaft that needs to be quenched into the storage box 1201 through the feed port, and then the motor shaft rolls on the inclined material table 1202 along the discharge port. When the motor shaft stops rolling, the propulsion cylinder 1203 pushes the motor shaft into the inclined material plate 1204, and then enters the guide barrel 10 with the inclination angle of the inclined material plate 1204, and then enters the box body 1 through the feed barrel 11 to start the quenching operation, and then the pneumatic clamp 404 clamps and fixes the motor shaft, and then the heating equipment 201 is started, and the already The part of the motor shaft entering the heating ring 203 is heated, and then the lifting cylinder 401 gradually moves the pneumatic clamp 404 downward through the connecting plate 402 and the fixing plate 403, so that the part of the motor shaft inside the heating ring 203 gradually moves downward. When the heating is completed, the heating device 201 is turned off, and the bottom of the motor shaft contacts the top of the support plate 9. At this time, the pneumatic clamp 404 releases the motor shaft and presses down the top of the support plate 9 through the bottom of the connecting plate 402, so that the support plate 9 moves downward. When the downward movement distance makes the motor shaft sufficient to break away from the heating ring 203, the motor shaft will fall downward under the action of its own gravity and fall into the cooling water tank 3. Then, due to the existence of the inclined plate 5, the motor shaft that falls into the cooling water tank 3 will roll down a distance, and the use of the motor shaft quenching processing device can be completed at this point.
