Description

Technical Field

[0001] This utility model relates to the field of bearing heat treatment technology, specifically to a bearing rapid quenching device. Background Technology

[0002] A bearing is a mechanical component whose main function is to support rotating shafts or other moving parts, reduce friction and wear during operation, and ensure rotational accuracy. Bearings play a crucial role in various mechanical equipment and devices.

[0003] Currently, in order to improve the hardness and wear resistance of bearings, they need to be heat-treated with a quenching device before being put into use, so as to improve the service life of the bearings.

[0004] In traditional technology, the assembly of bearings to be quenched in quenching devices is mostly achieved through fixtures. However, due to the limitations of the fixture structure, the number of bearings that can be assembled at one time is relatively small. Under continuous quenching conditions, the assembly of bearings requires a lot of time, making the overall process inefficient.

[0005] Based on this, we propose a rapid quenching device for bearings to solve the above problems. Utility Model Content

Both sides of the locking cylinder are provided with guide grooves and locking holes, and a locking channel is provided between the locking holes and the corresponding guide grooves.

[0015] A quick-assembly assembly is mounted on the top of the guide plate and is used to quickly assemble a limiting post by engaging with a locking hole.

[0037] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0038] like Figures 1-5 As shown, it illustrates a bearing rapid quenching device according to one embodiment of the present invention.

[0039] In some examples, including:

[0040] A support frame 1 is fixedly connected to a cooling box 2 on one side of the support frame 1, a high-frequency coil 3 is fixedly connected to the top of the support frame 1, and an adjustment frame 4 is fixedly connected to the other side of the support frame 1.

[0041] The transmission screw 5 is vertically rotatably connected to the middle of the adjusting frame 4. The top of the adjusting frame 4 is fixedly connected to the transmission motor 6, and the output end of the transmission motor 6 is fixedly connected to the transmission screw 5. The outer side of the transmission screw 5 is threadedly connected to the push frame 7.

[0042] The mounting component 8 is mounted on the top of the pusher frame 7 and is used to cooperate with the high-frequency coil 3 and the cooling box 2 to form a rapid quenching of the bearing.

[0043] For example, such as Figure 1 As shown, an observation channel is provided on one side of the cooling box 2. A transparent observation plate is fixedly connected inside the observation channel. The observation channel can provide a direct view of the remaining amount of quenching liquid inside the cooling box 2, so as to remind personnel to replenish it in time.

[0044] For example, such as Figure 1 As shown, the cooling box 2 is equipped with a drain pipe and a manual valve. The presence of the manual valve allows the quenching liquid to be conveniently drawn out of the cooling box 2.

[0045] In this embodiment, the high-frequency coil 3 includes:

[0046] The coil body, made of copper tube or copper strip, is responsible for generating an alternating magnetic field;

[0047] The insulating layer is used to prevent short circuits in the coil and ensure operational safety.

[0048] The cooling system is used to maintain the operating temperature of the coil;

[0049] The connection system is used to connect the coil body to an external high-frequency generator to ensure that electrical energy is effectively transferred to the coil;

[0050] The working principle is as follows: The high-frequency alternating current generated by the high-frequency generator passes through the coil, causing an alternating magnetic field to be generated in the coil. When the bearing is placed in the induction area of ​​the coil, the alternating magnetic field induces eddy currents in the bearing. According to Faraday's law of electromagnetic induction, the generation of eddy currents is proportional to the rate of change of the magnetic field. The eddy currents flow in the bearing material, and due to the resistance, the eddy currents generate heat, thus rapidly heating the bearing. By controlling the power output of the high-frequency generator, the temperature of the bearing can be precisely controlled to achieve the desired quenching effect.

[0051] In summary, the high-frequency coil 3 is a mature existing technology, and will not be elaborated further here;

[0052] For example, such as Figure 2 As shown, a linear guide rod is vertically fixedly connected to the inner side of the adjusting frame 4, and the pushing frame 7 is also slidably connected to the outer side of the linear guide rod. By setting the linear guide rod, the vertical displacement of the pushing frame 7 can be limited, preventing the pushing frame 7 from rotating with the transmission screw 5, which greatly ensures the stability of the pushing frame 7 when it is displaced.

[0053] For example, such as Figure 4 As shown, the mounting component 8 includes:

[0054] Mounting plate 9 is fixedly connected to the top of pusher frame 7. A support shaft A10 is vertically rotatably connected to one side of mounting plate 9. A guide plate 11 is fixedly connected to the top of support shaft A10. A support shaft B12 is fixedly connected to the top of guide plate 11.

[0055] Upright pole 13 is fixedly connected to the end of the mounting plate 9 away from the support shaft A10. An electric push rod 14 is rotatably connected to the outside of the upright pole 13, and the output end of the electric push rod 14 is rotatably connected to the support shaft B12.

[0056] The limiting post 15 has a limiting plate 16 fixedly connected to its bottom end and a locking cylinder 17 fixedly connected to its top end. Both sides of the locking cylinder 17 are provided with guide grooves 18 and locking holes 19, and a locking channel is provided between the locking holes 19 and the corresponding guide grooves 18.

[0057] The quick-release assembly is mounted on the top of the guide plate 11 and is used to quickly assemble the locking hole 19 to form the limiting post 15.

[0058] For example, such as Figure 4 As shown, the output end of the electric actuator 14 is fixedly connected to an assembly ring, which is sleeved on the outside of the support shaft B12. Multiple alloy balls are provided at the connection between the assembly ring and the support shaft B12. The assembly ring ensures that the output end of the electric actuator 14 can be stably connected to the support shaft B12. The alloy balls effectively reduce the wear of the electric actuator 14 when the support shaft B12 rotates.

[0059] For example, such as Figure 4 As shown, the guide plate 11 has a clearance through hole at one end near the limiting post 15, and the limiting post 15 is located inside the clearance through hole. By setting the clearance through hole, before the locking cylinder 17 and the insertion rod 21 are assembled, the limiting post 15 is first passed through the clearance through hole, so as to guide the vertical displacement of the limiting post 15 with the clearance through hole. After the limiting post 15 is assembled, the clearance through hole can be used to provide auxiliary support for the limiting post 15, so as to ensure the stability of the application of the limiting post 15.

[0060] For example, such as Figure 4 As shown, the quick-installation components include:

[0061] The drive motor 20 is fixedly connected to the top of the guide plate 11. The output end of the drive motor 20 is fixedly connected to the insertion rod 21, and the insertion rod 21 is inserted into the inside of the locking cylinder 17. Locking rods 22 are fixedly connected to both sides of the bottom of the insertion rod 21, and the two locking rods 22 are respectively engaged with the two locking holes 19.

[0062] For example, such as Figure 5 As shown, the width of the guide groove 18 is greater than the diameter of the locking rod 22, and the height of the locking channel is less than the diameter of the locking rod 22. Through the size changes of the guide groove 18 and the locking rod 22, the locking rod 22 can be smoothly adjusted inside the locking rod 22, thereby reducing the wear of the locking rod 22. Furthermore, through the size changes of the locking channel and the locking rod 22, when the locking rod 22 rotates towards the locking channel, it can compress the locking channel, causing the locking channel to deform until the locking rod 22 can pass through the locking channel and enter the locking hole 19. When the locking rod 22 reaches the inside of the locking channel, it will return to its original shape due to the loss of compression, thereby blocking the locking rod 22. In this embodiment, the material of the locking cylinder 17 can be stainless steel.

[0063] Working principle:

[0064] First, the bearings to be quenched are sequentially placed on the outside of the limiting post 15 and supported by the limiting plate 16. Then, the limiting post 15 with the bearing is adjusted to the bottom of the insertion rod 21, and the guide groove 18 is aligned with the locking rod 22. Then, the limiting post 15 is pushed upward, causing the locking sleeve 17 to be placed on the outside of the insertion rod 21, and the locking rod 22 to move vertically along the guide groove 18. When the locking rod 22 moves to the bottom of the guide groove 18, the drive motor 20 is started. With the connection between the drive motor 20 and the insertion rod 21, the insertion rod 21 can drive the locking rod 22 to rotate in the direction of the locking channel. As the locking rod 22 continues to rotate, the locking rod 22 will pass through the locking channel and be inserted into the locking hole 19, forming a quick lock of the limiting post 15. After the limiting post 15 is assembled, the bearing can be limited between the limiting plate 16 and the guide plate 11 with the help of the guide plate 11.

[0065] The high-frequency coil 3 and the drive motor 6 are started. The drive motor 6 is connected to the drive screw 5, which allows the drive screw 5 to rotate. With the drive screw 5 connected to the pusher frame 7, the pusher frame 7 can be vertically displaced along the drive screw 5 to adjust the assembled limit post 15 downward. When the bearing at the limit post 15 reaches the high-frequency coil 3, the high-frequency coil 3 can heat the bearing. As the pusher frame 7 gradually moves downward, the heated bearing will be immersed in the quenching liquid in the cooling box 2, so that the bearing can be cooled quickly, thereby achieving the quenching of the bearing.

[0066] After the bearing cools down, the drive motor 6 is started to move the pusher frame 7 upward and start the electric push rod 14. Since the electric push rod 14 is connected between the support shaft B12 and the upright 13, the electric push rod 14 can push the guide plate 11 to rotate under the support of the support shaft A10, so as to push the limiting post 15 to a position that is convenient for personnel to disassemble. Then, the personnel remove the limiting post 15 from the insertion rod 21 and replace it with another limiting post 15 with a bearing, so that the assembly of the next batch of bearings can be realized. This makes the quenching of the bearing more continuous and greatly improves the efficiency of bearing quenching.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
