Description

Technical Field

[0001] The present invention belongs to the technical field of automobile chassis nut production equipment, and specifically relates to a rapid cooling device for earthquake-resistant automobile chassis nuts. Background Art

[0002] Earthquake-resistant automobile chassis nuts, as indispensable fasteners for connecting various key components of the automobile chassis, play a crucial role. These nuts not only need to bear huge loads during vehicle driving, but are also often exposed to various harsh working environments, such as high temperature, humidity, vibration, etc. Therefore, their manufacturing quality and performance requirements are extremely strict.

[0003] During the processing of earthquake-resistant automobile chassis nuts, due to reasons such as plastic deformation and friction of metal materials, a large amount of heat will be generated in the nuts. If this heat cannot be dissipated and cooled in a timely and effective manner, it will have a serious impact on the processing quality and mechanical properties of the nuts. Specifically, too high a temperature may cause changes in the internal microstructure of the nut material, thereby affecting key performance indicators such as its hardness, toughness, and fatigue resistance. In addition, thermal stress may also cause the nut to deform or even crack during processing, seriously reducing its service life and reliability.

[0004] There is currently disclosed a rapid cooling device for nut processing with the publication number CN222528036U. Hot water with heat energy is discharged into the waste heat recovery pipe through the water outlet pipe. At the same time, the hot water is first purified and filtered by a filter box to adsorb impurities carried out by internal flushing. Then, the clean hot water is transported to the waste heat recovery equipment by the waste heat recovery pipe, which is beneficial to improving the energy utilization rate and optimizing the energy conservation and environmental protection of the equipment. After the nuts are cooled, the push rod is pulled to drive the placement rack and the nuts to move above the drain tank. At the same time, the upper fan and the side fan are used to air-dry the nuts, so that the airflow quickly takes away the moisture on the surface of the nuts.

[0005] In the working process of the above device, first, water is used to perform a preliminary cooling treatment on the nuts, and then the water stains on the outer surface of the nuts are dried by a fan. However, in actual operation, since the nuts are placed randomly, a series of potential problems will arise. The nuts may be placed in a stacked manner. This stacked state will greatly affect the air-drying effect when the fan performs the blowing and cooling operation. Specifically, the stacking between the nuts forms many dead corners, where the air flow is blocked, resulting in difficulty in effectively blowing away the moisture. The dead corners not only prolong the air-drying time and reduce the production efficiency, but may also form water stains or water spots on the surface of the nuts due to the long-term retention of moisture, affecting the appearance quality of the nuts. In extreme cases, if the moisture is not dried in time, it may cause rusting of the nuts, thereby having an adverse impact on the use performance and service life of the nuts.

[0006] Therefore, it is necessary to improve and optimize it. Summary of the Invention

[0007] In order to solve the problems in the above-mentioned background technology that when the nuts are cooled by blowing with a fan in a stacked state, the air flow is blocked due to the dead angles formed by stacking, affecting the air-drying effect, and further possibly causing water retention, damage to the appearance quality, and rust of the nuts, the present invention provides a quick-cooling device for anti-seismic automotive chassis nuts.

Specific embodiments

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] As Figures 1 to 8 shown, the present invention provides an anti-seismic type rapid cooling device for automotive chassis nuts, including a water tank 1. A bracket 2 is fixedly installed on the top of the water tank 1. A hollow barrel 3 is fixedly installed on the inner wall of the bracket 2. A cooling mechanism is arranged inside the hollow barrel 3;

[0034] The cooling mechanism includes a driving component and a rotating component; the rotating component includes a cover top 301 fixedly installed on the top of the hollow barrel 3. A lead screw 6 is fixedly installed on the inner wall of the top of the hollow barrel 3. Two sets of threads are provided on the outer wall of the lead screw 6 and the two sets of threads are provided in opposite directions. A bearing basket 7 is threadedly sleeved on the outer wall of the lead screw 6. Two mounting brackets 701 are rotatably installed on the outer wall of the bearing basket 7. The tops of the two mounting brackets 701 are respectively fixedly installed with a rack 8. A cover net 71 is clamped and installed on the inner wall of the top of the bearing basket 7. A limit ring 601 is fixedly installed at the bottom end of the lead screw 6. The outer diameter value of the limit ring 601 is greater than the outer diameter value of the lead screw 6.

[0035] Adopting the above scheme: by rotatably installing two mounting brackets 701 on the outer wall of the bearing basket 7, and fixedly installing racks 8 on the tops of the mounting brackets 701 respectively. When the bearing basket 7 moves up and down under the drive of the lead screw 6, since the rack 8 meshes with the gear in the driving component, the lifting of the rack 8 will drive the mounting bracket 701 and the bearing basket 7 itself to rotate. This rotational movement helps the nuts to be cooled more evenly during the cooling process and improves the cooling efficiency.

[0036] By driving the supporting basket 7 to rotate and move up and down through the motor 4, dynamic cooling of the nuts is achieved, which greatly accelerates the cooling speed. The rotating movement of the supporting basket 7 effectively prevents the nuts from stacking and ensures the uniformity of the cooling effect. In the water-drying stage and the air-drying step, centrifugal force and the fan 9 are used for drying, which effectively shortens the processing time. The entire work process has a high degree of automation. Only the motor 4 and the fan 9 need to be started to complete the cooling, water-drying and air-drying steps. The operation is simple and quick. The equipment is suitable for cooling treatment of nuts of different specifications and quantities, and has high flexibility and adaptability.

[0037] Through the cooperation of the driving assembly and the rotating assembly, the up and down and rotational movement of the supporting basket 7 and the internal nut is realized. This movement helps the nut to be heated and cooled more evenly, thereby improving the cooling efficiency. The overall structural design of the device is compact, and the space is fully utilized, making the device small in size and easy to move and install. The design of the limit ring 601 effectively prevents the supporting basket 7 from sliding down excessively, thereby enhancing the stability and safety of the device.

[0038] like Figures 2 to 6 As shown, the driving assembly includes a fixed block 101 fixedly mounted on the top of the water tank 1, a motor 4 is fixedly mounted on the top outer wall of the fixed block 101, a gear 1 401 is fixedly sleeved on the output shaft of the motor 4, four fixed plates 201 are fixedly mounted on the top of the bracket 2, two of the four fixed plates 201 are designed to be symmetrically distributed as a group, and rotating rods 5 are rotatably mounted on the sides of the two corresponding fixed plates 201 close to each other, and one end of the two rotating rods 5 close to the motor 4 extends out of the fixed plate 201, two gears 2 501 are fixedly sleeved on the outer walls of the two rotating rods 5, and the four gears 2 501 are respectively meshed with the corresponding gear rods 8, one end of one of the rotating rods 5 is fixedly connected to the output shaft of the motor 4, and a gear 3 502 is fixedly sleeved on the outer wall of the other rotating rod 5, and the gear 3 502 is meshed with the gear 1 401.

[0039] By adopting the above scheme: by setting a driving component, when the motor 4 receives a start signal, its output shaft starts to rotate, and the gear 401 fixedly mounted on the output shaft of the motor 4 rotates accordingly.

[0040] The third gear 502 meshing with the first gear 401 also starts to rotate. The third gear 502 is fixedly sleeved on the outer wall of one of the rotating rods 5. Therefore, this rotating rod 5 also starts to rotate. At the same time, since the two rotating rods 5 are respectively installed on the top of the bracket 2 through the fixing plates 201 and are connected by a gear system, when one of the rotating rods 5 rotates, the other rotating rod 5 will also rotate synchronously. Two second gears 501 are respectively and fixedly sleeved on the outer walls of the two rotating rods 5. These four second gears 501 respectively mesh with the corresponding toothed rods 8. When the rotating rod 5 rotates, the second gear 501 drives the toothed rod 8 to move in the vertical direction. Due to the meshing action of the gears, the moving direction of the toothed rod 8 is related to the rotating direction of the gear. Usually, the rotating motion is converted into the linear motion of the toothed rod 8 through the rotation of the gear. The movement of the toothed rod 8 drives the up and down movement of the mounting frame 701 and the carrying basket 7. At the same time, since the carrying basket 7 is threadedly connected to the lead screw 6, the carrying basket 7 will also perform a rotational motion along the axis of the lead screw 6 while moving up and down.

[0041] As Figure 4 shown, a water guide groove 10 is formed on the inner wall of the hollow barrel 3, and the water guide groove 10 is designed in a threaded shape.

[0042] With the above solution: by setting the water guide groove 10, during the cooling and air drying process of the nuts, when the carrying basket 7 carries the cooled nuts and moves up and down and rotates inside the hollow barrel 3, the water droplets that may remain on the nuts or the carrying basket 7 will be thrown out and adhered to the inner wall of the hollow barrel 3. The threaded shape of the water guide groove 10 can guide these water droplets to flow along a specific path, rather than randomly dripping onto the bottom of the hollow barrel 3 or accumulating on the inner wall. As the water droplets flow in the water guide groove 10, they will eventually be guided to the bottom of the hollow barrel 3 or a specific drain outlet, thereby achieving effective drainage.

[0043] As Figures 1 to 2 shown, two blowers 9 are fixedly installed on the outer wall of the hollow barrel 3, and the air outlets of the two blowers 9 are both communicated with the hollow barrel 3.

[0044] With the above solution: by setting the blowers 9, during the operation of the nut cooling device, when the carrying basket 7 carries the cooled nuts and rises from the water tank 1 and enters the hollow barrel 3, at this time, the two blowers 9 are started. The air flow generated by the blowers 9 is directly introduced into the hollow barrel 3 through their air outlets. Since the air outlets of the blowers 9 are communicated with the hollow barrel 3, the air flow can be evenly distributed inside the hollow barrel 3, thereby achieving efficient air drying of the carrying basket 7 and the nuts inside it.

[0045] As Figure 1 shown, four circular grooves 3011 are formed on the top of the cover top 301. The positions of the four circular grooves 3011 respectively coincide with the corresponding toothed rods 8 in the vertical direction and are slidably connected to the corresponding toothed rods 8.

[0046] Adopting the above solution: By setting the circular grooves 3011, when the device is running, when the motor 4 starts and drives the gear system to rotate, the toothed rod 8 moves in the vertical direction due to the meshing action of the second gear 501. At this time, the top part of the toothed rod 8 slides along the four circular grooves 3011 opened on the cover top 301, ensuring the stability and guiding property of the toothed rod 8 during the movement, and avoiding device failures or efficiency reduction caused by unstable movement.

[0047] The working principle and usage process of the present invention:

[0048] First, fill the water tank 1 with cooling water to ensure there is enough medium for the cooling process.

[0049] Open the cover net 71, neatly place the nuts to be cooled into the carrying basket 7, and then buckle the cover net 71 to fix the nuts and prevent them from scattering;

[0050] Start the motor 4. The output shaft of the motor 4 rotates to drive the first gear 401 and the rotating rod 5 fixedly connected to the motor 4 to rotate. Through the meshing of the first gear 401 and the third gear 502, the third gear 502 and the rotating rod 5 fixedly connected to the third gear 502 are driven to rotate, so that the two rotating rods 5 rotate simultaneously. Through the two rotating rods 5, the corresponding two second gears 501 are driven to rotate. Through the meshing of the four second gears 501 and the toothed rod 8, the four toothed rods 8 convert the rotational movement of the four second gears 501 into vertical movement along the axis of the toothed rod 8;

[0051] First, the four toothed rods 8 drive the mounting frame 701 and the carrying basket 7 to move downward. Due to the threaded connection between the carrying basket 7 and the lead screw 6, when the carrying basket 7 moves downward, it can simultaneously rotate along the axis of the lead screw 6, effectively dispersing the nuts to prevent stacking and ensuring uniform cooling effect;

[0052] When the carrying basket 7 is completely immersed in the cooling water in the water tank 1, the nuts start to be cooled.

[0053] During the cooling process, the motor 4 rotates forward and reverses alternately, making the carrying basket 7 move up and down and rotate simultaneously in the cooling water. This dynamic cooling method greatly speeds up the cooling speed of the nuts.

[0054] After cooling is completed, start the motor 4 again to make the carrying basket 7 rise out of the water tank 1 and enter the hollow barrel 3.

[0055] In the hollow barrel 3, the carrying basket 7 also makes multiple up-and-down and simultaneous rotational movements to use centrifugal force to throw out the excess water stains attached to the outer wall of the nuts;

[0056] Finally, move the carrying basket 7 to the middle of the two blowers 9, and start the two blowers 9 to blow-dry the carrying basket 7 and the nuts inside the carrying basket 7. Also, perform the up-and-down and simultaneous rotation movements multiple times to make the air-drying effect better and faster.

[0057] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.
