Description

Technical Field

[0001] This utility model relates to the field of lead screw cooling technology, specifically to a lead screw cooling device. Background Technology

[0002] In modern industrial production, lead screws, as key components of mechanical transmission systems, are widely used in CNC machine tools, automated equipment, and other fields. With the continuous increase in equipment operating speed and precision requirements, the mounting end of the lead screw generates a large amount of heat during high-speed operation. If heat is not dissipated in time, thermal deformation will occur at the lead screw end, thereby affecting the machining accuracy and service life of the equipment. Therefore, efficient cooling devices are crucial for ensuring the stable operation of the lead screw.

[0003] Currently, most cooling devices for lead screw ends on the market use coolant circulation for heat dissipation. However, these devices generally have a significant problem: it is inconvenient to clean the coolant channels. During long-term use, metal shavings, impurities, and scale formed by the reaction of coolant chemicals with metal surfaces carried in the coolant will gradually adhere to the inner walls of the coolant channels. Over time, these impurities and scale will accumulate, easily causing blockages in the coolant channels.

[0004] Once the channel is blocked, the flow of coolant will be greatly reduced, or even partially interrupted, resulting in a sharp drop in cooling efficiency. This will fail to meet the heat dissipation requirements for the continuous and stable operation of the lead screw, and in severe cases, it may even cause the lead screw to overheat and be damaged, increasing equipment maintenance costs and downtime, and affecting the continuity and efficiency of industrial production. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model proposes a lead screw cooling device to solve the technical problem mentioned in the background art: existing cooling devices for lead screw ends are inconvenient to clean the coolant channels, and after long-term use, the coolant channels are easily blocked by impurities and scale, affecting the flow of coolant and thus reducing the cooling effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lead screw cooling device, comprising:

[0007] Mounting bracket, used to support the end of the lead screw body;

[0008] A cooling seat is detachably mounted on one side of the mounting base. The end of the lead screw body is rotatably mounted inside the cooling seat. The cooling seat is provided with a loop-shaped passage formed by multiple straight passages. The end of the straight passage is connected to the outside, and a sealing component is provided at the connection point.

[0009] Two sets of liquid passages are provided on the cooling seat, and both are connected to the outside environment and one of the straight passages; and

[0010] A separator is detachably disposed within one set of the straight passages to isolate the two sets of liquid passages.

[0011] In a preferred embodiment, the sealing assembly includes a sealing seat, which is screwed to the connection between the straight passage and the outside, and a sealing head is provided on the inner side of the straight passage.

[0012] In a preferred embodiment, the separating component includes:

[0013] A partition column is disposed within the straight passage, and multiple sets of sealing rings are fitted on the partition column, with the sealing rings abutting against the inner wall of the straight passage;

[0014] A threaded head is disposed at one end of the partition post and screwed into the interior of the straight passage; and

[0015] A disassembly head is located at the other end of the partition column, and the disassembly head has a hole inside that matches the disassembly tool.

[0016] In a preferred embodiment, one set of the liquid passages is provided with a detachable inlet pipe connector, and the other set of the liquid passages is provided with a detachable outlet pipe connector.

[0017] In a preferred embodiment, a connecting seat is provided on one side of the cooling seat, the connecting seat is disposed within the mounting seat, and a fixing bolt is provided on the mounting seat, the fixing bolt passing through the connecting seat.

[0018] In a preferred embodiment, a bearing is provided inside the cooling seat, the end of the lead screw body passes through the bearing, and a detachable shield is also provided on one side of the cooling seat, the shield abutting against the bearing.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] In use, this device allows coolant to flow through one set of liquid passages into a loop-shaped passage formed by multiple straight passages. A separating component then isolates one set of straight passages, allowing the coolant to flow sequentially through several sets of straight passages and exit from another set, achieving coolant circulation within the cooling seat and cooling the mounting end of the lead screw. Furthermore, the multiple blocking and separating components can be disassembled, allowing cleaning tools such as brushes or metal rods to be inserted into the straight passages through the end connected to the outside. This cleans the straight passages and pushes the cleaning tools to expel impurities from the cooling seat, quickly and thoroughly cleaning the coolant flow path and effectively preventing impurities from accumulating and obstructing coolant flow, thus improving the cooling effect on the end of the lead screw.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention. Those skilled in the art can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0028] Example:

[0029] like Figure 1 ,3 As shown, this utility model provides a lead screw cooling device, including a mounting base 1 for supporting the end of the lead screw body 17. A cooling seat 3 is detachably provided on one side of the mounting base 1. The end of the lead screw body 17 is rotatably disposed in the cooling seat 3. A connecting seat 4 is provided on one side of the cooling seat 3 and is disposed in the mounting base 1. A fixing bolt 5 is provided on the mounting base 1 and passes through the connecting seat 4. A bearing 2 is provided in the cooling seat 3, and the end of the lead screw body 17 passes through the bearing 2. A detachable shielding seat 6 is also provided on one side of the cooling seat 3, and the shielding seat 6 abuts against the bearing 2.

[0030] During use, the end of the lead screw body 17 can be supported by the mounting base 1, the smoothness of the lead screw body 17 during rotation can be increased by the bearing 2, and the wear of the end of the lead screw body 17 can be reduced. The installation of the bearing 2 can be limited by the shielding base 6 to prevent the bearing 2 from shifting. The cooling base 3 can be disassembled by removing the fixing bolt 5, which facilitates the maintenance of the cooling base 3.

[0031] like Figure 1 , 2 As shown, in this embodiment, the cooling base 3 is provided with a loop-shaped passage formed by multiple straight passages 8. The ends of the straight passages 8 are connected to the outside, and a sealing component is provided at the connection point. The sealing component includes a sealing seat 15, which is screwed onto the connection point between the straight passage 8 and the outside. A sealing head 16 is provided on the inner side of the sealing seat 15 within the straight passage 8. The cooling base 3 is also provided with two sets of liquid passages 7, both of which are connected to the outside and one of the straight passages 8. One set of liquid passages 7 is provided with a detachable water inlet pipe connector 9, and the other set of liquid passages 7 is provided with a detachable water outlet pipe connector 10.

[0032] The inlet pipe connector 9 can be connected to a coolant inlet pipe, and the outlet pipe connector 10 can be connected to a coolant outlet pipe. Coolant can enter the cooling base 3 through the inlet pipe connector 9 and exit through the outlet pipe connector 10, realizing the circulation of coolant within the cooling base 3, thereby cooling the mounting end of the lead screw body 17. The end of the straight passage 8 is sealed by the sealing seat 15 to prevent coolant from flowing out through the straight passage 8.

[0033] like Figure 2 As shown, in this embodiment, a separator assembly is detachably installed within one set of straight passages 8 to isolate the two sets of liquid passages 7. The separator assembly includes a separator post 11 installed within the straight passage 8, with multiple sets of sealing rings 14 fitted on the separator post 11. The sealing rings 14 abut against the inner wall of the straight passage 8. One end of the separator post 11 is provided with a threaded head 13, which is screwed into the inside of the straight passage 8. The other end of the separator post 11 is provided with a disassembly head 12, which has a hole for matching disassembly tools.

[0034] The partition column 11 and its sealing ring 14 isolate the loop-shaped passage, allowing the coolant to flow sequentially through multiple straight passages 8 and out through the outlet pipe joint 10 after entering the cooling base 3 through the inlet pipe joint 9. This increases the residence time of the coolant in the cooling base 3 and improves the uniformity of cooling. When cleaning the inside of the cooling base 3 is required, the disassembly head 12 can be rotated with a disassembly tool to disengage the threaded head 13 from the straight passage 8, allowing the partition column 11 to be removed. Then, the cleaning tool can be used to push out impurities from the straight passage 8 and the liquid passage 7 into the cooling base 3, improving the cleaning effect and ensuring the flow of coolant.

[0035] The specific usage and beneficial effects of this utility model are as follows:

[0036] In use, this device allows coolant to flow through one set of liquid passages 7 into a loop-shaped passage formed by multiple sets of straight passages 8. The separating components then isolate one set of straight passages 8, allowing the coolant to flow sequentially through several sets of straight passages 8 and out through another set of liquid passages 7. This achieves coolant circulation within the cooling seat 3, cooling the mounting end of the lead screw body 17. Furthermore, after disassembling the multiple blocking and separating components, cleaning tools such as cleaning brushes or metal rods can be inserted into the straight passages 8 through the end connected to the outside to clean them. The cleaning tools can be pushed to expel impurities from the straight passages 8 out of the cooling seat 3, quickly and thoroughly cleaning the coolant flow path. This effectively prevents impurities from accumulating and obstructing coolant flow, improving the cooling effect on the end of the lead screw body 17.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above. Modifications or improvements can be made to this utility model, which is obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of this utility model fall within the scope of protection claimed by this utility model.
