Description

Technical Field

[0001] This utility model belongs to the field of machine tool technology and relates to a machine tool cutting fluid supply structure. Background Technology

[0002] When machine tool tools operate for extended periods, the temperature of both the tool and the workpiece rises, affecting the machining accuracy of the machine tool. To reduce the temperature of the workpiece and the tool, cutting fluid needs to be sprayed while the machine tool is operating.

[0003] Patent application number CN201811355153.2 discloses an intelligent cooling device for CNC machine tools with adjustable cutting fluid flow, including a nozzle head, a hose, a flow sensor, a flow regulating valve, a single-chip microcomputer control unit, a spindle box, and a cutting tool.

[0004] The above-mentioned device still has shortcomings: when applied to machine tools where the tool position can be adjusted by moving the tool holder, it is often necessary to adjust the nozzle position of the hose by a large span. However, when the hose is too long, the increased deflection makes it difficult to ensure the stability of the spray position after adjustment. Summary of the Invention

[0005] This utility model addresses the aforementioned problems in existing technologies by providing a machine tool cutting fluid supply structure. The technical problem this utility model aims to solve is that existing machine tool cutting fluid supply devices are difficult to adapt to adjustable tool holders.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A machine tool cutting fluid supply structure is disclosed. The machine tool includes a machine base, an X-axis tool holder, and a Y-axis tool holder. The X-axis tool holder is movable laterally along the machine base, and the Y-axis tool holder is mounted on the X-axis tool holder. The supply structure includes a universal cooling hose and a fluid supply pipe for delivering cutting fluid. The structure further includes a positioning pipe, which is a rigid pipe arranged vertically and fixed to the outside of the X-axis tool holder. The fluid supply pipe is a flexible pipe, with one end extending out of the outer wall of the machine base and connected to the lower end of the positioning pipe. The inlet end of the universal cooling hose is connected to the upper end of the positioning pipe, and the outlet end of the universal cooling hose faces the Y-axis tool holder.

[0008] The X-axis tool holder on the machine base can be adjusted laterally along the machine base, while the Y-axis tool holder can be adjusted longitudinally, so that the tool set on the Y-axis tool holder can perform machining in a suitable position. The liquid supply pipe is used to connect with the existing liquid supply pump to deliver pressurized cutting fluid. The universal cooling hose is an existing pipe fitting that can maintain its deformed posture after being subjected to force, making it easy to align the liquid outlet with the tool machining area to achieve a better cooling effect. By setting a rigid positioning tube, the positioning tube is fixed to the outside of the X-axis tool holder, while the liquid supply tube extends out of the outer wall of the machine base and is connected to the lower end of the positioning tube. The universal cooling hose is connected to the upper end of the positioning tube. In this way, the rigid positioning tube can move synchronously with the X-axis tool holder. Even if the Y-axis tool holder is also adjusted, only the position of the liquid outlet of the universal cooling hose needs to be finely adjusted. Under the condition that the positioning tube provides rigid support, the overall length of the universal cooling hose will not be too long, ensuring good rigidity and spray position stability. The liquid supply tube, which is made of soft material, can reserve a redundant length so that it can adapt to deformation after being stretched, avoiding interference and stabilizing the liquid supply. This makes it better compatible with machine tools with adjustable tool holders and achieves a stable supply of cutting fluid to the tool.

[0009] In the aforementioned machine tool cutting fluid supply structure, the outer wall of the machine base has a clearance hole through which the fluid supply pipe extends. The outer side of the X-axis tool holder has a support bar extending laterally along the machine base towards the side where the clearance hole is located. The support bar is supported on the upper side of the machine base, and the positioning tube is fixed to the outer side of the support bar. This facilitates the fluid supply pipe's connection to the positioning tube as soon as it exits the machine base, minimizing the required design length of the fluid supply pipe and ensuring a reliable and stable fluid supply path. Simultaneously, the stable support of the support bar on the upper side of the machine base ensures the stability of the positioning tube's position.

[0010] In the above-described machine tool cutting fluid supply structure, the outer end of the relief hole is rounded. This helps to ensure that the fluid supply pipe is not damaged by contact with the outer end of the relief hole when it is pulled during the movement of the X-axis tool holder.

[0011] In the aforementioned machine tool cutting fluid supply structure, the universal cooling hose is Y-shaped and has two outlet ends. This allows the operator to independently adjust the two outlet ends of the universal cooling hose to different angles to align with different positions of the cutting tool, thereby achieving a better cooling effect on the tool.

[0012] In the aforementioned machine tool cutting fluid supply structure, the inlet end of the universal cooling hose has a control valve that can control its on / off state. This allows the operator to conveniently shut off the cutting fluid supply via the control valve when the position of the universal cooling hose needs adjustment, followed by direct adjustment. Once adjustment is complete, it can be easily restarted for continued use, making the process more convenient.

[0013] Compared with the prior art, the advantages of this utility model are as follows:

[0014] The cutting fluid supply structure of this machine tool is equipped with a rigid positioning tube that can move synchronously with the X-axis tool holder. Even if the Y-axis tool holder is also adjusted, only the position of the outlet end of the universal cooling hose needs to be finely adjusted. With the rigid support provided by the positioning tube, the overall length of the universal cooling hose will not be too long, ensuring good rigidity and spray position stability. This allows it to be well adapted to machine tools with adjustable tool holders, achieving a stable supply of cutting fluid to the tools. Attached Figure Description

[0016] Figure 2 This is a three-dimensional schematic diagram of the combined state of the universal cooling hose and the positioning tube in this embodiment.

[0017] In the diagram, 1 is the machine base; 11 is the clearance hole; 2 is the X-axis tool holder; 21 is the support bar; 3 is the Y-axis tool holder; 4 is the universal cooling hose; 41 is the control valve; 5 is the liquid supply pipe; and 6 is the positioning pipe. Detailed Implementation

[0018] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0019] like Figure 1 As shown, this machine tool includes a machine base 1, an X-axis tool holder 2, and a Y-axis tool holder 3. The X-axis tool holder 2 can move laterally along the machine base 1. The Y-axis tool holder 3 is mounted on the X-axis tool holder 2. The drive structure of the X-axis tool holder 2 and the Y-axis tool holder 3 can refer to existing lead screw transmission mechanisms. The supply structure includes a universal cooling hose 4 and a coolant supply pipe 5 that can deliver cutting fluid. The supply structure also includes a positioning pipe 6, which is a rigid pipe arranged in the vertical direction. The positioning pipe 6 is fixed to the outside of the X-axis tool holder 2. The coolant supply pipe 5 is a flexible pipe. One end of the coolant supply pipe 5 extends out of the outer wall of the machine base 1 and is connected to the lower end of the positioning pipe 6. The other end of the coolant supply pipe 5 is connected to an existing liquid pump (not shown) located inside the machine base 1. The inlet end of the universal cooling hose 4 is connected to the upper end of the positioning pipe 6, and the outlet end of the universal cooling hose 4 is set towards the Y-axis tool holder 3. The outer wall of the machine base 1 has a relief hole 11. The outer end of the relief hole 11 is rounded. One end of the liquid supply pipe 5 passes through the relief hole 11. The outer side of the X-axis tool holder 2 has a support bar 21 extending laterally along the machine base 1 towards the side where the relief hole 11 is located. The support bar 21 is supported on the upper side of the machine base 1. The positioning tube 6 is fixed to the outer side of the support bar 21.

[0020] like Figure 2 As shown, the universal cooling hose 4 is Y-shaped and has two liquid outlets. The liquid inlet of the universal cooling hose 4 has a control valve 41 that can control the on / off state.

[0021] When adjusting the tool position, the rigid positioning tube 6 can move synchronously with the X-axis tool holder 2. Even if the Y-axis tool holder 3 is also adjusted, only the position of the liquid outlet of the universal cooling hose 4 needs to be slightly adjusted to adapt to the displacement of the Y-axis tool holder 3. The deformation range of the universal cooling hose 4 is small, which can ensure cooling stability.
