Description

Technical Field

[0001] This utility model relates to the field of machine tool spindle technology, and more specifically to a machine tool spindle center outlet water cooling device. Background Technology

[0002] The machine tool spindle is one of the core functional components of a machine tool. It is a key actuator for realizing machining operations such as cutting, drilling, and milling, and its performance directly determines the machining accuracy, efficiency, and stability of the machine tool. Structurally, a machine tool spindle typically consists of a spindle body, bearing assembly, transmission mechanism (such as pulleys, gears, or couplings), and front-end fixture interface (for mounting tools or workpieces). Some high-precision spindles also integrate sensors for speed detection and temperature monitoring.

[0003] A search revealed a spindle center water cooling device (authorization number CN220463166U), comprising a spindle body: a machining drill bit is disposed at the bottom of the spindle body; a movable block is movably sleeved inside the spindle body; a water inlet pipe is fixedly sleeved on the outer surface of the movable block; a first groove is provided inside the spindle body; a flexible hose is fixedly connected to the bottom end of the first groove; and a nozzle is hinged to the bottom of the spindle body via a round shaft. Water spray holes are provided on both sides of the bottom of the machining drill bit. Coolant can be introduced into the first groove through the water inlet pipe, and the water flow will then enter the nozzle through the flexible hose, thereby cooling the outer side of the machining drill bit. Simultaneously, the interaction between the machining drill bit and the first groove allows the water flow to cool the interior of the machining drill bit and spray out through the water spray holes, thus improving the cooling effect.

[0004] The shortcomings of the existing technology are as follows: The above technology requires manual adjustment of the spray angle of the nozzle by the operator. Manual adjustment requires stopping the machine and cannot adjust the angle in real time according to the processing conditions during continuous processing of the machine tool. As a result, the cooling water flow cannot be applied to the core heat-generating area of ​​the cutting in a timely and accurate manner, resulting in insufficient cooling targeting and a significant reduction in cooling efficiency.

[0005] Therefore, there is a need to provide a machine tool spindle center water cooling device to solve the above-mentioned problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a machine tool spindle center water cooling device to solve the problems existing in the background art.

[0007] This utility model provides the following technical solution: a machine tool spindle center water cooling device, including a spindle body, a top block fixedly connected to the top of the spindle body, a diverter plate fixedly connected to the bottom of the spindle body, a main channel groove opened in the middle of the spindle body, the top block and the diverter plate, diverter grooves opened near both sides inside the spindle body, the top block and the diverter plate, a main water outlet pipe fixedly connected to the inner wall of the main channel near the bottom, and auxiliary water outlet pipes fixedly connected to the inner walls of the two diverter grooves near the bottom, the top of the two auxiliary water outlet pipes being a flexible hose structure, and two supports fixedly connected to the outer wall of the diverter plate in an alternating manner;

[0008] The machine tool spindle center outlet water cooling device also includes:

[0009] Two adjustment components are respectively disposed on the inner walls of opposite sides of the two supports, and are used to adjust the spray angle of the two adjustment components;

[0010] Preferably, the adjustment component includes:

[0011] The U-shaped frame has its outer wall fixedly connected to the inner wall of the support. A limiting post is fixedly connected to the inside of the U-shaped frame near the right side. A limiting block is movably sleeved on the outer wall of the limiting post located inside the U-shaped frame. A fixing block is fixedly connected to the right side of the limiting block. The middle part of the fixing block is fixedly sleeved on the outer wall of the auxiliary water outlet pipe.

[0012] The guide mechanism is located on the outer wall of the U-shaped frame and is used to drive the limiting block to rotate on the outer wall of the limiting column, thereby adjusting the angle of the fixed block and the auxiliary water outlet pipe.

[0013] Preferably, the guiding mechanism includes a cylinder, which is disposed inside the bracket. A U-shaped slide rod is fixedly connected to the top of the cylinder. A second limiting post is fixedly connected near the top of the U-shaped slide rod. A guide block is movably sleeved on the outer wall of the second limiting post located on the U-shaped frame. The right side of the guide block is fixedly connected to the outer wall of the limiting block.

[0014] Preferably, the U-shaped frame has convex sliding grooves in the middle of both sides, and square sliding grooves in the middle of both convex sliding grooves. The outer wall of the limiting post 2 is slidably connected in the square sliding groove, and the inner walls of both sides of the U-shaped sliding rod are slidably connected in the two convex sliding grooves.

[0015] Preferably, the guide block has a through groove in the middle, and the outer wall of the limiting post 2 is movably sleeved in the through groove in the middle of the guide block.

[0016] Preferably, a limit block is fixedly connected to the inner wall of the bracket, the limit block is fixedly connected to the outer wall of the cylinder, and the cylinder is electrically connected to the PLC controller.

[0017] The technical effects and advantages of this utility model are as follows:

[0018] 1. This utility model, by incorporating a main flow channel and branch flow channels, forms a multi-directional water cooling structure with a central and two-sided outlet. This facilitates simultaneous cooling of the central area and key components on both sides of the spindle body, significantly expanding the cooling coverage area and preventing overheating caused by localized heat accumulation. This extends the spindle's service life and improves machining accuracy. Furthermore, the inclusion of an adjustment component, with the cylinder electrically connected to a PLC controller, allows for precise PLC control of the cylinder drive. This drives the U-shaped slide bar to slide along the convex slide groove, causing the second limiting post to slide within the square slide groove. This, in turn, rotates the guide block to adjust the angle, which in turn causes the limiting block to rotate the secondary water outlet pipe around the first limiting post, achieving flexible and precise adjustment of the secondary water outlet pipe's spray angle. The cooling water jet direction can be adjusted according to different processing conditions to ensure that the cooling water flow is precisely applied to the cutting area, improving the targeting and efficiency of cooling. The sliding fit structure of the convex slide groove, square slide groove, U-shaped slide rod, and limit post II, as well as the limit block connecting the inner wall of the bracket to the cylinder, can accurately limit the movement trajectory of the U-shaped slide rod and stably fix the cylinder, avoiding cooling angle deviation caused by structural shaking, and ensuring the consistency and reliability of cooling effect. The movable sleeve structure of the through groove in the middle of the guide block and the limit post II can reduce the movement interference between components, ensure smooth and stable angle adjustment, reduce mechanical wear, improve the service life of the adjustment components and the response speed of the adjustment action, and facilitate quick adaptation to the cooling needs of different processing scenarios.

A fixing block 604 is fixedly connected to the right side of the limiting block 605, and the middle part of the fixing block 604 is fixedly sleeved on the outer wall of the auxiliary water outlet pipe 5.

[0032] The guide mechanism is located on the outer wall of the U-shaped frame 601 and is used to drive the limiting block 605 to rotate on the outer wall of the limiting post 606, thereby adjusting the angle of the fixed block 604 and the auxiliary water outlet pipe 5.

[0033] The guiding mechanism includes a cylinder 603, which is located inside the bracket 7. A U-shaped slide rod 602 is fixedly connected to the top of the cylinder 603. A limit post 608 is fixedly connected near the top of the U-shaped slide rod 602.

The right side of the guide block 610 is fixedly connected to the outer wall of the limit block 605.

[0034] The U-shaped frame 601 has convex sliding grooves 607 in the middle of both sides, and square sliding grooves 609 in the middle of both convex sliding grooves 607. The outer wall of the limiting post 608 is slidably connected in the square sliding groove 609, and the inner walls of both sides of the U-shaped slide rod 602 are slidably connected in the two convex sliding grooves 607.

[0035] A through groove is provided in the middle of the guide block 610, and the outer wall of the limiting post 608 is movably sleeved in the through groove in the middle of the guide block 610.
