Description

Technical Field

[0001] This utility model relates to the field of spindle technology, and in particular to a heat dissipation structure for a spindle and a spindle. Background Technology

[0002] With the development of industrial technology, the requirements for heat dissipation performance of various mechanical equipment are becoming increasingly stringent. As a key component of the equipment, if the heat generated during operation cannot be dissipated in a timely and effective manner, it will seriously affect the service life and working efficiency of the equipment, thereby restricting the overall production efficiency.

[0003] In traditional spindle cooling, engineers typically carve straight cooling channels into the spindle housing and install corresponding vents at both ends. This "channel + port" structure allows external airflow to pass through the channels and carry away the heat generated during spindle operation, achieving basic cooling. However, due to the lack of a guiding function for cool airflow, the airflow cannot circulate flexibly and requires a longer time to lower the spindle temperature. This not only reduces cooling efficiency but also directly affects the stability of subsequent spindle operation, thereby shortening its overall lifespan. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that there is no guiding function for cold airflow, the cold airflow is difficult to circulate flexibly, and it takes a long time to reduce the spindle temperature. Therefore, this invention proposes a heat dissipation structure for the spindle and a spindle.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A heat dissipation structure for a spindle and a spindle, comprising a mounting base 1 and a mounting base 2, wherein the same housing is fixedly disposed on the opposite sidewalls of the mounting base 1 and the mounting base 2, and a plurality of guide grooves 1 and a plurality of guide grooves 2 are respectively opened at both ends of the housing. An air inlet pipe and an air outlet pipe are fixedly disposed on the mounting base 1 and the mounting base 2, and the air inlet pipe and the air outlet pipe are both connected to the guide grooves 1 and the guide grooves 2.

[0006] Preferably, both the first and second guide channels are fixedly connected with partitions.

[0007] Preferably, both the first guide channel and the second guide channel are U-shaped.

[0008] Preferably, both the first guide channel and the second guide channel are arranged in a ring array.

[0009] Preferably, the first guide channel and the second guide channel are arranged in a staggered adjacent manner.

[0010] Preferably, each of the partition plates has a screw hole at its end.

[0011] Preferably, both the first mounting base and the second mounting base are threadedly connected to the screw hole with the same mounting bolt.

[0012] Preferably, dustproof parts are fixedly provided on the opposite sidewalls of both the first mounting base and the second mounting base, and several heat dissipation blocks are fixedly provided on the dustproof parts.

[0014] A spindle, comprising a spindle body with a heat dissipation structure installed in it.

[0015] Compared with the prior art, the advantages of this utility model are as follows: This invention, through the design of components such as guide channel one and guide channel two, allows for efficient cooling during the heat dissipation operation. Cooling airflow, composed of cold compressed air, enters the housing through the inlet pipe. Two sets of U-shaped, staggered guide channels, guided by a partition, create a meandering flow path within the channels, ensuring the airflow fully contacts the housing and spindle, efficiently absorbing heat from both. The airflow then carries the heat away through the outlet pipe, further improving heat dissipation efficiency and ensuring stable operation and extended service life of the spindle.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figures 1-5 A heat dissipation structure for a spindle and the spindle itself are disclosed. The spindle includes a mounting base 1 and a mounting base 2, which serve as the basic load-bearing components of the entire heat dissipation structure. These two mounting bases form a stable assembly frame, providing a solid mounting reference for core components such as the housing 4, the inlet pipe 45, and the outlet pipe 46. This split design not only facilitates individual processing and subsequent maintenance and replacement of each component but also ensures the overall structural airtightness through precise alignment, preventing leakage of cooling airflow and guaranteeing stable heat dissipation efficiency. It should be noted that the spindle body 3 is preferably, but not limited to, fixed to the mounting bases 1 and 2 using bolts, facilitating the disassembly and assembly of the housing 4. Mounting base 1 and mounting base 2 are fixedly mounted on opposite side walls of the same housing 4. Several guide channels 41 and several guide channels 42 are respectively opened at both ends of the housing 4. The housing 4 serves as an intermediate carrier connecting mounting base 1 and mounting base 2. The guide channels 41 and 42 at both ends are key channels for achieving efficient heat dissipation. The guide channels are connected to the inlet pipe 45 and the outlet pipe 46, forming a complete airflow circulation path, allowing the cooling medium to flow directly across the surface of the housing 4 and quickly remove the heat generated during spindle operation. Both mounting base 1 and mounting base 2 are fixedly equipped with inlet pipes 45 and 46, and both inlet pipes 45 and 46 are connected to the guide channels 41 and 42.

[0020] Both the first guide channel 41 and the second guide channel 42 are fixedly connected with baffles 43.

[0021] Both the first guide channel 41 and the second guide channel 42 are U-shaped. The U-shaped structure extends the flow path of the cooling medium within the guide channel, increasing the contact time and contact area between the medium and the shell 4, thereby improving heat exchange efficiency. Compared to straight channels, the U-shaped design allows the cooling medium to more fully envelop the inner wall of the channel, enhancing the heat dissipation effect.

[0022] Both the first guide channel 41 and the second guide channel 42 are arranged in a ring array. The ring array layout ensures that the guide channels are evenly distributed at the ends of the housing 4, ensuring that the cooling medium can act on the surface of the housing 4 in all directions, avoiding the problem of excessive temperature caused by uneven local heat dissipation. This arrangement is compatible with the cylindrical structure of the spindle body 3 and conforms to the characteristic of uniform heat diffusion in the circumferential direction.

[0023] The first guide channel 41 and the second guide channel 42 are arranged in a staggered adjacent manner. The staggered layout further optimizes the flow path of the cooling medium, so that the flow of the medium in the adjacent guide channels does not interfere with each other. At the same time, it increases the airflow disturbance, promotes turbulent heat transfer between the medium and the channel wall, effectively improves the heat dissipation efficiency, and avoids the local airflow stagnation that may occur when parallel arrangement.

[0024] Several baffles 43 have screw holes 44 at their ends. The baffles 43 in the flow guide channel can divert and guide the cooling medium, ensuring that the medium flows along a preset path and avoiding short circuits. At the same time, they enhance the structural strength of the flow guide channel and prevent the channel from deforming due to pressure or temperature changes. The screw holes 44 at the ends of the baffles 43 provide connection points for fixing the mounting base to the housing 4, ensuring the stability of the assembly.

[0025] Both mounting base 1 and mounting base 2 are threadedly connected to screw hole 44 with the same mounting bolt 6. This connection method is not only simple in structure and convenient to install, but also facilitates subsequent disassembly, maintenance, and component replacement, reducing maintenance costs. The reliability of the bolt connection also ensures that the components will not loosen due to vibration during high-speed spindle operation.

[0026] Dustproof sections 5 are fixedly installed on the opposite sidewalls of both mounting base 1 and mounting base 2, and several heat dissipation blocks 51 are fixedly installed on the dustproof sections 5. The dustproof sections 5 on the opposite sidewalls of the mounting bases can effectively prevent external dust and impurities from entering the internal structure, and prevent dust from adhering to the guide groove or the surface of the spindle body 3, which would affect the heat dissipation effect and working accuracy. The heat dissipation blocks 51 on the dustproof sections 5 increase the contact area with the air, and further assist in heat dissipation through natural convection, complementing the forced cooling of the guide groove and improving the overall heat dissipation performance.

[0027] A retaining ring 7 is fixedly connected to the dustproof part 5, and the retaining ring 7 is threadedly connected to both mounting base 1 and mounting base 2. The retaining ring 7 not only enhances the installation stability of the dustproof part 5, but also facilitates its assembly and disassembly. The adjustability of the threaded connection allows the fit between the dustproof part 5 and the mounting base to be adjusted as needed, ensuring the dustproof effect without affecting the heat dissipation channel of the overall structure.

[0028] The functional principle of this utility model can be explained through the following operational methods: During the heat dissipation operation phase: The cooling airflow (cold compressed air) enters from the intake pipe 45. Because the first guide groove 41 and the second guide groove 42 are U-shaped and staggered, the airflow is guided by the baffle 43 and forms a meandering flow path in the groove, fully contacting the housing 4 and the main shaft. After absorbing heat, it is discharged from the exhaust pipe 46.

[0029] Meanwhile, the dustproof section 5 prevents external impurities from entering the device, and the heat dissipation block 51 on its surface assists in heat conduction, further improving heat dissipation efficiency and ensuring stable operation of the spindle.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
