Description

Technical Field

[0001] This utility model belongs to the field of cooling rack technology, and specifically relates to a cooling rack for mechanical parts. Background Technology

[0002] Mechanical parts cooling racks are key equipment used in industrial production for cooling mechanical parts after processing. Their core function is to quickly reduce the residual high temperature of parts after processing through efficient heat dissipation, preventing the parts from undergoing thermal deformation due to continuous high temperature and affecting dimensional accuracy. Most current mechanical parts cooling racks adopt a multi-layer frame structure, combined with a fan assembly to achieve forced air cooling. By neatly placing the parts on the support position of the frame, the airflow generated by the fan blows on the surface of the parts, achieving heat exchange through forced convection. It is suitable for the cooling needs of various conventionally shaped mechanical parts such as bearings, gears, and housings.

[0003] A search revealed that CN115031485A discloses a cooling rack for mechanical parts. It includes a base, a fixedly connected bottom plate on the base, a fixedly connected support frame on the bottom plate, a fixedly connected baffle on the support frame, a partition at the center of the inner wall of the two side baffles, a cooling device below the partition, a first part rack and a second part rack above the partition, the first part rack and the second part rack being slidably connected to the inner walls of the two side baffles on both sides, and a heat-absorbing plate above the first part rack at the top of the support frame, with a number of heat-conducting holes on the surface of the heat-absorbing plate.

[0004] When existing mechanical parts cooling racks are used to cool tubular mechanical parts, the airflow from the cooling rack can only act on the outer surface of the part because the tubular part has a hollow inner ring area. The inner ring area is surrounded by the part's own structure, making it difficult for airflow to enter and form effective circulation, resulting in the heat in the inner ring not being able to dissipate in time. Utility Model Content

[0005] The purpose of this utility model is to provide a cooling rack for mechanical parts, so as to solve the problem mentioned in the background art that the air blowing of the cooling rack for mechanical parts can only act on the outer surface of the parts, while the inner area is surrounded by the structure of the parts themselves, making it difficult for airflow to enter and form effective circulation, resulting in the heat in the inner area not being able to dissipate in time.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A cooling rack for mechanical parts, comprising:

[0008] A support tube, the interior of which is hollow to form a cold air delivery channel for delivering cooling airflow;

[0009] A placement plate is fixedly installed on a support tube. The placement plate has a cavity inside, which is connected to the support tube.

[0010] The placement plate includes several air blowing pipes installed on the placement plate. The air blowing pipes are connected to the cavity. Several air blowing holes are provided on the peripheral wall of the air blowing pipes. The mechanical parts are sleeved on the air blowing pipes, and the air outlet of the air blowing pipes is set towards the inner wall of the mechanical parts to deliver cooling airflow to the inner area of ​​the mechanical parts.

[0011] Preferably, the support tube comprises:

[0012] The air supply duct extends from one end into the cold air delivery channel of the support duct and from the other end into the cavity of the placement plate, and is used to guide the cooling airflow in the cold air delivery channel into the cavity.

[0013] Preferably, the number of air supply pipes is at least two, and they are arranged in a circular array along the circumference of the support pipe.

[0014] Preferably, the end of the blower tube near the placement plate has a circular opening, which is sealed and connected to the cavity of the placement plate, and the diameter of the circular opening is the same as the inner diameter of the blower tube.

[0015] Preferably, the blower tube is provided with a limiting mechanism, which is used to fix the axial position of the mechanical parts on the blower tube.

[0016] Preferably, the limiting mechanism includes:

[0017] The mounting base is fixedly installed on the outer peripheral wall of the blower tube;

[0018] The support arm has a groove on one side of the fixed base. One end of the support arm is rotatably connected to the groove via a pivot, and the other end extends out of the groove and is used to abut against the inner wall of the mechanical part.

[0019] An elastic element, installed between the inner wall of the groove and the support arm, is used to apply an elastic force toward the outside of the groove to the support arm.

[0020] Preferably, the number of fixed bases and support arms is at least three, and they are arranged in a circular array along the circumference of the blower pipe.

[0024] Preferably, the placement plate is annular.

[0025] This invention provides a cooling rack for mechanical parts. Compared with existing technologies, it offers the following advantages: The air blower extends directly into the inner ring area of ​​the mechanical part, delivering cooling airflow towards the inner ring wall. Simultaneously, the support pipe, air supply pipe, and placement plate cavity together form a complete airflow transmission channel, allowing the cooling airflow to be directed into the inner ring and form effective circulation, reducing the temperature difference between the inner and outer rings of the mechanical part. The placement plates are linearly arrayed along the length of the support pipe, making full use of longitudinal space. Each placement plate is equipped with multiple air blowers, allowing a single placement plate to simultaneously cool multiple tubular parts. Multiple placement plates increase the overall cooling capacity of the equipment. The limiting mechanism can adapt to the inner ring dimensions of tubular parts of different specifications, ensuring the support arm always remains close to the inner ring wall, maintaining a suitable distance between the air blower and the inner ring wall, neither obstructing airflow nor affecting the cooling effect.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-5 A cooling rack for mechanical parts, comprising:

[0034] Support tube 200, the support tube 200 is hollow to form a cold air delivery channel for delivering cooling airflow;

[0035] A placement plate 300 is fixedly installed on a support tube 200. The placement plate 300 has a cavity 301 inside, which is connected to the support tube 200.

[0036] The placement plate 300 includes several air blowing pipes 400, which are installed on the placement plate 300. The air blowing pipes 400 are connected to the cavity 301. Several air blowing holes 401 are provided on the peripheral wall of the air blowing pipes 400. The mechanical parts are sleeved on the air blowing pipes 400, and the air outlet of the air blowing pipes 400 is set towards the inner ring wall of the mechanical parts to deliver cooling airflow to the inner ring area of ​​the mechanical parts.

[0037] In the above technical solution, the hollow structure of the support tube 200 is used as the main channel for cooling airflow, and the cavity 301 inside the placement plate 300 is used to divert the cooling airflow, so that the cold air delivered by the support tube 200 is evenly distributed to the air blowing pipe 400 on the placement plate 300; the air blowing hole 401 on the air blowing pipe 400 can directly face the inner ring wall, so that the cooling airflow forms a directional flow in the inner ring of the part and carries away the heat of the inner ring wall.

[0038] The support pipe 200 includes an air supply pipe 201, one end of which extends into the cold air delivery channel of the support pipe 200, and the other end extends into the cavity 301 of the placement plate 300, for guiding the cooling airflow in the cold air delivery channel into the cavity 301.

[0039] Specifically, the air supply duct 201 extends to the cold air delivery channel of the support duct 200 and the cavity 301 of the placement plate 300 at both ends, forming a directional transmission path of cooling airflow from the main channel to the cavity 301. This reduces the diffusion loss of airflow during transmission and also provides support, making the placement plate 300 more stable on the support duct 200.

[0040] The number of air supply pipes 201 is at least two, and they are arranged in a circular array along the circumference of the support pipe 200 to achieve uniform distribution of cooling airflow in the cavity 301.

[0041] Specifically, at least two air supply pipes 201 arranged in a circular array along the circumference of the support pipe 200 can simultaneously deliver cooling airflow to the cavity 301 of the placement plate 300 from different circumferential positions of the cold air delivery channel of the support pipe 200, avoiding the phenomenon of local airflow concentration in the cavity 301 caused by a single air supply pipe 201, and making the airflow form a circumferential symmetrical diffusion in the cavity 301.

[0042] The blower 400 has a circular opening at one end near the placement plate 300. The circular opening is sealed and connected to the cavity 301 of the placement plate 300, and the diameter of the circular opening is the same as the inner diameter of the blower 400 to prevent the cooling airflow from leaking at the connection.

[0043] The air blower 400 is provided with a limiting mechanism, which is used to fix the axial position of the mechanical parts on the air blower 400, to prevent the mechanical parts from tilting on the air blower 400, or the inner ring wall of the mechanical parts from being too close to the air outlet of the air blower 400, while ensuring that the air outlet of the air blower 400 is always aligned with the inner ring wall of the tubular mechanical parts.

[0044] In the above technical solution, the limiting mechanism can prevent the mechanical parts from tilting by fixing the axial position of the mechanical parts on the air blowing pipe 400, and prevent the air outlet from being misaligned with the inner ring wall of the parts; in addition, the limiting mechanism can also control the inner ring wall of the mechanical parts to maintain a certain distance from the air outlet, so as to avoid the airflow being blocked due to the distance being too close or the cooling efficiency being reduced due to the distance being too far.

[0045] The limiting mechanism includes:

[0046] The mounting base 402 is fixedly installed on the outer peripheral wall of the blower 400;

[0047] The support arm 403 has a groove on one side of the fixed base 402. One end of the support arm 403 is rotatably connected to the groove through a rotating shaft, and the other end extends out of the groove and is used to abut against the inner ring wall of the mechanical part.

[0048] The elastic element 404 is installed between the inner wall of the groove and the support arm 403 to apply an elastic force toward the outside of the groove to the support arm 403, so that the support arm 403 always fits tightly against the inner wall of the tubular mechanical part.

[0049] Specifically, the elastic element 404 is a V-shaped elastic sheet or a spring; the limiting mechanism can also be several blocks, which can be used to position the mechanical parts and the blower pipe 400; the support arm 403 forms a hinge structure through the rotational connection between the rotating shaft and the groove, so that the support arm 403 can swing around the rotating shaft to adapt to mechanical parts with different inner ring diameters; the elastic element 404 forms a preload between the inner wall of the groove and the support arm 403, and the outward pushing force generated by its elastic deformation forces the support arm 403 to always keep in contact with the inner ring wall of the part, so as to realize the positioning of the mechanical parts, satisfy the limiting function and also have adaptability.

[0050] The number of fixed bases 402 and support arms 403 is at least three, and they are arranged in a circumferential array along the circumference of the blower pipe 400 to achieve coaxial positioning of tubular mechanical parts on the blower pipe 400 and avoid radial displacement of the parts.

[0051] It also includes a blower 100, which is fixedly installed at the bottom of the support tube 200. The air outlet of the blower 100 is connected to the cold air delivery channel inside the support tube 200 through a sealing joint, and is used to continuously deliver a cooling airflow with a pressure of 0.1-0.3MPa to the cold air delivery channel.

[0052] The number of placement plates 300 is at least two, and they are arranged in a linear array along the length of the support tube 200. The distance between any two adjacent placement plates 300 is 100-1000mm, so as to avoid the tubular mechanical parts on adjacent placement plates 300 from blocking each other's airflow during the cooling process, and to facilitate the handling of parts.

[0053] The placement plate 300 is circular. The central through hole of the circular placement plate 300 is welded and fixed to the outer wall of the support tube 200. The upper surface of the placement plate 300 is provided with anti-slip protrusions to increase the friction between the mechanical parts and the placement plate 300 and to assist the limiting mechanism in fixing the position of the parts.

[0054] During use, the operator places the tubular mechanical part to be cooled onto the air blower 400. Under the outward elastic force of the elastic element 404, the support arm 403 rotates around the groove of the fixed seat 402 via a rotating shaft and extends outwards, its end tightly against the inner wall of the part. This achieves coaxial positioning of the part on the air blower 400, preventing radial offset and axial tilt, while ensuring a suitable distance between the inner wall of the part and the air blowing holes 401 on the circumference of the air blower 400. The blower 100, installed at the bottom of the support tube 200, is then activated, delivering cold air into the support tube 200 through a sealed connector. The channel continuously delivers cooling airflow; the cooling airflow flows in the cold air delivery channel of the support pipe 200 and is directionally transmitted through the air supply pipe 201. The air supply pipe 201 guides the cooling airflow from the main channel to the cavity 301. The cooling airflow entering the cavity 301 is evenly distributed under the circumferential symmetrical diffusion effect, and then enters the air supply pipe 400 through the circular opening near the end of the placement plate 300. The cooling airflow in the air supply pipe 400 is directly blown onto the inner wall of the tubular part through the air blowing holes 401 on the peripheral wall, forming a directional flow in the inner circle of the part to quickly remove heat. After cooling is completed, the part is removed.
