Description

Technical Field

[0001] This utility model relates to the field of machining equipment technology, specifically a cooling structure for a horizontal lathe spindle box. Background Technology

[0002] In the field of machining, horizontal lathes, as core equipment for metal cutting, generate a large amount of heat during high-speed operation of transmission components such as gears and bearings in their headstock. If this heat cannot be dissipated in time, the temperature of the components will rise, causing the viscosity of the lubricating oil to decrease and the lubrication effect to weaken. This, in turn, will exacerbate component wear, reduce transmission accuracy, and in severe cases, cause deformation of the headstock, affecting the dimensional accuracy and surface quality of the machined workpiece, and even leading to equipment failure.

[0003] A search revealed existing technology (application number: CN205438007U), which describes a "cooling structure for CNC machine tool spindle box". This utility model introduces cooling oil into a chamber formed by inner and outer layers through an oil inlet. The oil flows through a flow channel formed by a partition with through holes, and in conjunction with the outer heat sink and related structures, it cools the spindle box. Finally, the oil flows out from the oil outlet.

[0004] However, the device lacks the function of precisely adjusting the spray angle of the cooling medium, as well as impurity filtration and cooling medium recovery structures, resulting in poor cooling targeting and resource utilization. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cooling structure for the spindle box of a horizontal lathe.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a cooling structure for a horizontal lathe spindle box, comprising: a spindle box body; a cooling assembly including a feed pipe, a conveying channel, a support ring, and a spray pipe, wherein the feed pipe is fixedly connected to the side wall of the spindle box body, the conveying channel is disposed inside the side wall of the spindle box body and communicates with the feed pipe, the support ring is fixedly connected to the inner wall of the spindle box body, and both ends of the spray pipe are rotatably connected to the support ring; and an adjustment assembly including an adjustment ring and a rack, wherein the adjustment ring is fixedly connected to the spray pipe, the rack slides on the inner wall of the spindle box body, and the rack meshes with the adjustment ring.

[0007] As a further description of the above technical solution:

[0008] A filter screen is bolted inside the feed pipe.

[0009] As a further description of the above technical solution:

[0010] The spray pipe has a segmented structure, with each segment rotatably connected. Each segment connection is equipped with a sealing ring, and each segment is fixedly connected with a nozzle.

[0011] As a further description of the above technical solution:

[0012] A material collection box is slidably connected to the bottom of the spindle housing.

[0013] As a further description of the above technical solution:

[0014] A control plate slides on the side wall of the spindle housing, and a connecting plate slides inside the side wall of the spindle housing. The two ends of the connecting plate are welded to the control plate and the rack, respectively.

[0015] As a further description of the above technical solution:

[0016] The connecting plate is provided with a locking module, which includes: positioning holes evenly distributed on the inner wall of the spindle housing; and locking pins that are slidably connected to the connecting plate and slidably in contact with the positioning holes.

[0017] As a further description of the above technical solution:

[0018] The locking module also includes a spring, with its two ends fixedly connected to the connecting plate and the locking pin, respectively.

[0019] This utility model has the following beneficial effects:

[0020] Firstly, it enables directional delivery and precise spraying of the cooling medium, effectively intercepting impurities to avoid channel blockage, while expanding the cooling coverage area, ensuring the sealing of the conveying system, efficiently absorbing gear heat, and realizing the recovery of the cooling medium for easy subsequent processing.

[0021] Secondly, the nozzle angle can be flexibly adjusted, and the angle can be manually controlled to achieve stable locking after adjustment, improving the ease of operation, taking into account both targeted cooling and usage flexibility, and ensuring the continuous and stable operation of the spindle box gears.

[0033] Example 1:

[0034] like Figures 1 to 6As shown, this embodiment provides a cooling structure for a horizontal lathe spindle box, including: a spindle box body 1; a cooling assembly 2, including a feed pipe 21, a conveying channel 23, a support ring 24, and a spray pipe 25. The feed pipe 21 is fixedly connected to the side wall of the spindle box body 1, the conveying channel 23 is disposed inside the side wall of the spindle box body 1 and communicates with the feed pipe 21, the support ring 24 is fixedly connected to the inner wall of the spindle box body 1, and both ends of the spray pipe 25 are rotatably connected to the support ring 24; and an adjustment assembly 3, including an adjustment ring 31 and a rack 34. The adjustment ring 31 is fixedly connected to the spray pipe 25, the rack 34 slides on the inner wall of the spindle box body 1, and the rack 34 meshes with the adjustment ring 31.

[0035] In this embodiment, the spindle box 1, the cooling assembly 2, and the adjustment assembly 3 constitute a horizontal lathe spindle box cooling structure according to this application.

[0036] Understandable, Figure 1 The diagram only schematically illustrates some of the components included in the headstock of a horizontal lathe; the actual shape, size, location, and construction of these components are not subject to change. Figure 1 Due to limitations, the headstock of a horizontal lathe can also include, compared to... Figure 1 More or fewer parts.

[0037] Example 2:

[0038] Specifically, a filter screen 22 is bolted inside the feed pipe 21.

[0039] Specifically, the spray tube 25 has a segmented structure, with each segment rotatably connected. Each segment connection is equipped with a sealing ring, and each segment of the spray tube 25 is fixedly connected with a nozzle.

[0040] Specifically, a material collection box 26 is slidably connected to the bottom of the main spindle housing 1.

[0041] In this embodiment, when the cooling medium flows through the feed pipe 21, it is intercepted by the filter screen 22 to filter impurities in the cooling medium, thereby preventing blockage of the conveying channel 23 and the spray pipe 25. The spray pipe 25 can be rotated in sections to adjust the angle of each section. The sealing ring prevents the cooling medium from leaking. The nozzle atomizes and sprays the cooling medium to expand the cooling coverage area and ensure the sealing of the cooling medium conveying. The cooling medium drips after absorbing heat and falls into the collection box 26 for collection, realizing the recovery of the cooling medium and facilitating subsequent processing.

[0042] Example 3:

[0043] Specifically, a control plate 32 slides on the side wall of the spindle housing 1, and a connecting plate 33 slides inside the side wall of the spindle housing 1. The two ends of the connecting plate 33 are welded to the control plate 32 and the rack 34, respectively.

[0044] Specifically, the connecting plate 33 is provided with a locking module 35, which includes: positioning holes 351, which are evenly distributed on the inner wall of the spindle housing 1; and locking pins 352, which are slidably connected to the connecting plate 33 and slidably contact the positioning holes 351.

[0045] Specifically, the locking module 35 also includes a spring 353, which is fixedly connected at both ends to the connecting plate 33 and the locking pin 352, respectively.

[0046] In this embodiment, the sliding control plate 32 drives the connecting plate 33 to slide, thereby driving the rack 34 to move, realizing manual control of the adjustment component 3, providing power transmission for nozzle angle adjustment. When the locking pin 352 is inserted into the positioning hole 351, it fixes the position of the connecting plate 33. When it is pulled out, it unlocks, realizing the position locking of the control plate 32, ensuring stability after nozzle angle adjustment. In its natural state, the spring 353 pushes the locking pin 352 into the positioning hole 351. Pressing the locking pin 352 compresses the spring 353 to unlock, realizing the automatic reset of the locking pin 352, improving the convenience of locking operation.

[0047] In actual use, the user first connects the feed pipe 21 to the oil conveying equipment. The feed pipe 21 delivers cooled lubricating oil to the spray pipe 25 through the conveying channel 23. The lubricating oil is sprayed from the nozzle of the spray pipe 25 onto the gear to cool it. The lubricating oil that absorbs the heat of the gear flows into the collection box 26. After cooling, the collection box 26 can be removed to replace or process the lubricating oil. If the nozzle angle needs to be adjusted, the control plate 32 can be unlocked by moving the locking pin 352. Then, the control plate 32 is slid. The control plate 32 drives the rack 34 through the connecting plate 33. The rack 34 causes the adjusting ring 31 to rotate, thereby rotating the spray pipe 25 to adjust the nozzle angle.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
