Description

Technical Field

[0001] This invention belongs to the field of machine tool accessories technology, specifically a water-cooled tool post for a CNC lathe. Background Technology

[0002] The CNC tool turret is one of the most common auxiliary devices on CNC lathes, used to hold the cutting tools. It allows the CNC lathe to complete multiple or even all machining operations in a single workpiece clamping, thereby shortening auxiliary machining time, reducing errors caused by multiple workpiece setups, and improving the machine tool's machining efficiency and accuracy. CNC machine tool turrets can be divided into rack-type turrets and rotary turrets. Rack-type turrets are generally used on small-sized CNC lathes, primarily for machining bar stock or disc-shaped parts. Rotary turrets are the most commonly used typical tool changer on CNC lathes, typically using a hydraulic or electrical system to achieve automatic tool changing. Depending on the machining requirements, they can be designed as square, hexagonal, or disc-type turrets, and correspondingly accommodate 4, 6, or more cutting tools.

[0003] A conventional disc tool holder consists of a rotatable disc on which a tool is mounted. The disc rotates to align with a tool mounting bracket, and a hydraulic system pushes the tool. In practice, although the corresponding tool on the tool holder is pushed onto the mounting bracket, the tools on the entire disc tool holder can still be displaced. In case of misoperation, it is difficult to quickly align the tool holder section without a tool with the mounting bracket section, which may lead to a tool collision accident and results in low safety redundancy.

[0004] Meanwhile, in order to reduce the heat generated by the cutting tool during processing, a water cooling system is installed near the tool. This system uses high-pressure water to cool down the tool and remove debris. This operation is activated even when the tool is not properly installed. Since each tool has a different advance position, the position of the water cooling head must be switched when changing tools to achieve the correct water cooling. The overall operation is quite cumbersome. Summary of the Invention

[0005] The purpose of this invention is to provide a water-cooled tool post for CNC lathes to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a water-cooled CNC lathe tool post, comprising a frame, a servo motor fixedly mounted on the left side of the frame, a tool holder fixedly mounted on the output end of the servo motor, slots equally spaced on the outer side of the tool holder, CNC tools movably engaged within each slot, an extension bracket fixedly mounted on the front end of the servo motor, a tool mounting bracket fixedly mounted on one side of the extension bracket in front of the slots, an mounting slot for mounting CNC tools inside the tool mounting bracket, a groove on the right side of the tool holder, a tool locking assembly mounted inside the groove, a water-cooling assembly movably mounted in the middle of the right end of the tool locking assembly, a tool pushing assembly fixedly connected near the bottom of the outer side of the water-cooling assembly to one side of the tool mounting bracket, the tool mounting bracket and the tool pushing assembly being arranged parallel to each other, a limit hole being provided near the rear end of the CNC tool, and the outer side of the water-cooling assembly being fixedly sleeved with the frame.

[0007] Before using the device, it can be installed on the corresponding position of the CNC machine tool, and one end of the tool feeding assembly can be connected to an external water pump. High-pressure water is then pumped into the device through the external water pump. In the initial state, the tool locking assembly and the water cooling assembly are both in the initial state, and all CNC tools are located inside the slot. The tool mounting bracket is not equipped with any tools in the initial state.

[0008] As a further technical solution of the present invention, the tool locking assembly includes a limiting plate, and a limiting groove is formed at an equal angle on the front side of the limiting plate. A limiting rod is movably engaged inside the limiting groove. The limiting rod moves back and forth relative to the limiting groove. The diameter of the limiting rod is the same as the inner diameter of the limiting hole.

[0009] As a further technical solution of the present invention, the tool locking assembly further includes a fixing tube, one end of which is connected to one end of the groove, a movable plate is movably sleeved inside the fixing tube, one end of the movable plate is fixedly connected to a return spring located inside the fixing tube, and the other end of the return spring is connected to one end of the inner cavity of the fixing tube.

[0010] As a further technical solution of the present invention, a movable rod is fixedly connected to the end of the movable plate away from the reset spring, and one end of the movable rod passes through one end of the fixed tube and is connected to the middle of the limiting plate.

[0011] As a further technical solution of the present invention, when the reset spring is in the initial state, the limiting rod is located directly above the limiting hole, and when the reset spring is in the extreme compression state, the limiting rod and the limiting hole are movably engaged.

[0012] When switching tools, the servo motor can be turned on to drive the tool holder to rotate. At this time, the tool locking component rotates synchronously, and the tool holder rotates relative to the water cooling component. As the tool holder rotates, the CNC tool can rotate circumferentially relative to the tool holder. When the corresponding CNC tool rotates to the tool mounting bracket and is located directly behind the tool mounting bracket, the tool holder stops rotating and waits for the tool loading process.

[0013] As a further technical solution of the present invention, the water cooling assembly includes a water storage pipe, which is fixedly sleeved with the frame. A first piston plate is movably sleeved inside the water storage pipe. A first piston rod is fixedly connected to one end of the first piston plate near the limiting plate. The first piston rod passes through one end of the water storage pipe and is movably connected to the limiting plate. The limiting plate rotates relative to the first piston rod.

[0014] As a further technical solution of the present invention, the end of the water storage pipe away from the limiting plate is fixedly connected to a water inlet valve, and the other end of the water inlet valve is connected to an external water pump.

[0015] During tool loading, an external water pump can be turned on to input high-pressure water into the inlet valve. At this time, the high-pressure water enters the water storage pipe and pushes the first piston plate to the left, simultaneously driving the first piston rod to the left. When the first piston rod moves to the left, it applies pressure to the limiting plate, causing the limiting plate to move closer to the tool holder. At this time, the movable rod and movable plate move to the left and compress the return spring. When the return spring is compressed to its limit position, the distance between the limiting plate and the tool holder is at its minimum. At this time, multiple limiting rods insert into the limiting holes, thus completing the limiting process for all CNC tools. At this time, all CNC tools not corresponding to the tool mounting bracket are limited and cannot move, completing the locking process.

[0016] By utilizing the high-pressure water input from the outside during water cooling, the device can automatically lock unused tools during tool changing and tool installation, preventing tool displacement. The entire process can be completed automatically before tool changing, effectively avoiding the probability of tool collision during tool changing and tool installation in traditional devices, thus reducing safety hazards.

[0017] As a further technical solution of the present invention, the tool propulsion assembly includes a propulsion tube, the rear end of which is fixedly connected to a first water supply hose. The first water supply hose is connected to the outer side of the water storage pipe near the left side. When the first piston plate is displaced to the leftmost side of the water storage pipe, the first piston plate is located on the left side of the output end of the first water supply hose. A second piston plate is movably sleeved inside the propulsion tube.

[0018] As a further technical solution of the present invention, a second piston rod is fixedly connected to the end of the second piston plate away from the first water supply hose, and a push clamp located behind the limiting rod is fixedly connected to the end of the second piston rod away from the second piston plate. A limiting spring is movably sleeved on the outer side of the second piston rod, and the two ends of the limiting spring are connected to one end of the second piston plate and one end of the inner cavity of the push tube.

[0019] As a further technical solution of the present invention, a high-pressure nozzle is fixedly connected to the right side of the propulsion clamp. The output end of the high-pressure nozzle is located on one side of the tool mounting bracket. A second water supply hose is fixedly connected to the rear end of the high-pressure nozzle. The other end of the second water supply hose is connected to the outer side of the propulsion tube near the front end.

[0020] When the tool is installed, i.e., when the first piston plate is moved to the leftmost position and the limit rod is locked with the CNC tool, high-pressure water is introduced into the inside of the feed tube through the first water supply hose. At the same time, the second piston plate is pushed forward. At this time, the limit spring can be compressed, which in turn drives the second piston rod to move forward. Since the CNC tool and the tool mounting bracket are corresponding to each other at this time, and the limit rod has completed the locking process with the CNC tool, the feed clamp can then contact the limit rod located at the rearmost side and push the limit rod to move forward relative to the limit groove. At this time, the CNC tool is also displaced relative to the groove until the CNC tool is installed inside the tool mounting bracket. At this time, the limit rod is located at the outermost side of the limit groove, completing the tool installation process.

[0021] By utilizing externally input high-pressure water, the system can lock the position of unused CNC tools while simultaneously pushing the CNC tools to be used directly into the tool mounting bracket for installation. The entire process can be completed automatically after the CNC tools are locked, enabling rapid tool installation. Simultaneously, during reset, the CNC tools can be automatically retracted and the locking of the CNC tools can be automatically released, significantly improving tool loading efficiency and overall tool changing speed.

[0022] After the CNC tool and the tool mounting bracket are installed, high-pressure water is then discharged through the second water supply hose. At the same time, the forward displacement of the push clamp can synchronously pull the high-pressure nozzle forward. When the push clamp is in place, the output end of the high-pressure nozzle is also located on one side of the tool mounting bracket, corresponding to the CNC tool that is installed. At the same time, the high-pressure water discharged through the second water supply hose can be directly sprayed out through the high-pressure nozzle and act on the CNC tool to complete the cooling and debris removal process.

[0023] By directly utilizing the imported high-pressure water and the tool's advancement and installation process, the system automatically adjusts the position of the high-pressure nozzle, automatically positions the high-pressure nozzle, and directly outputs high-pressure water to cool the CNC tool. This avoids the problem of traditional devices requiring adjustment of the high-pressure nozzle position every time the CNC tool is switched. The entire process can be completed automatically, effectively simplifying the operation steps and improving the overall tool changing efficiency.

[0024] The beneficial effects of this invention are as follows:

[0025] (1) By utilizing the high-pressure water input from the outside during water cooling, the device can automatically lock the unused tool when changing and installing the tool, so that the tool cannot be moved. The whole process can be completed automatically before tool changing, which can effectively avoid the problem of tool collision that occurs when the tool can still be moved during tool changing and tool installation in traditional devices, thus reducing safety hazards.

[0026] (2) This invention utilizes the imported high-pressure water and the tool's push-in installation process to automatically adjust the position of the high-pressure nozzle, automatically position the high-pressure nozzle, and directly output high-pressure water to complete the cooling process of the CNC tool. This avoids the problem that traditional devices need to adjust the position of the high-pressure nozzle every time the CNC tool is switched. The whole process can be completed automatically, effectively simplifying the operation steps and improving the overall tool changing efficiency.

[0027] (3) By utilizing externally input high-pressure water, the present invention can lock the position of the unused CNC tool while pushing the CNC tool to be used directly into the tool mounting bracket and completing the installation. The entire process can be completed automatically after the CNC tool is locked, quickly realizing the tool installation process. At the same time, the CNC tool can be automatically retracted and the CNC tool lock can be automatically released during reset, which significantly improves the tool loading efficiency and the overall tool changing speed.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] like Figures 1 to 8 As shown in the embodiment of the present invention, a water-cooled CNC lathe tool post includes a frame 1. A servo motor 2 is fixedly installed on the left side of the frame 1. A tool holder 5 is fixedly installed at the output end of the servo motor 2. The outer side of the tool holder 5 has slots 6 at equal angles. CNC tools 7 are movably engaged inside the slots 6. An extension frame 3 is fixedly installed at the front end of the servo motor 2. A tool mounting frame 4 located directly in front of the slots 6 is fixedly installed on one side of the extension frame 3. The tool mounting frame 4 has a mounting slot for mounting CNC tools 7 inside. A groove 9 is opened on the right side of the tool holder 5. A tool locking component 10 is installed inside the groove 9. A water-cooling component 11 is movably installed in the middle of the right end of the tool locking component 10. A tool pushing component 12 located on one side of the tool mounting frame 4 is fixedly connected to the outer side of the water-cooling component 11 near the bottom end. The tool mounting frame 4 and the tool pushing component 12 are arranged in parallel. A limit hole 8 is opened at the position of the CNC tool 7 near the rear end. The outer side of the water-cooling component 11 is fixedly sleeved with the frame 1.

[0039] Before using the device, it can be installed on the corresponding position of the CNC machine tool, and one end of the tool feeding assembly 12 can be connected to the external water pump. High-pressure water is input into the device through the external water pump. At the same time, in the initial state, the tool locking assembly 10 and the water cooling assembly 11 are both in the initial state, and all CNC tools 7 are located inside the slot 6. The tool mounting bracket 4 does not have any tools installed in the initial state.

[0040] like Figure 3 and Figure 4 as well as Figure 5 and Figure 6 As shown, the tool locking assembly 10 includes a limiting plate 101. Limiting grooves 102 are formed at equal angles on the front of the limiting plate 101. Limiting rods 103 are movably engaged inside each limiting groove 102. The limiting rods 103 move back and forth relative to the limiting grooves 102. The diameter of the limiting rods 103 is the same as the inner diameter of the limiting holes 8. The tool locking assembly 10 also includes a fixing tube 104. One end of the fixing tube 104 is connected to one end of the groove 9. A movable plate 106 is movably sleeved inside the fixing tube 104. One end of the movable plate 106 is fixedly connected to a positioning device. The return spring 107 is located inside the fixed tube 104. The other end of the return spring 107 is connected to one end of the inner cavity of the fixed tube 104. The movable plate 106 is fixedly connected to the end away from the return spring 107 with a movable rod 105. One end of the movable rod 105 passes through one end of the fixed tube 104 and is connected to the middle of the limiting plate 101. When the return spring 107 is in the initial state, the limiting rod 103 is located directly above the limiting hole 8. When the return spring 107 is in the ultimate compression state, the limiting rod 103 is movably engaged with the limiting hole 8.

[0041] When switching tools, the servo motor 2 can be turned on to drive the tool holder 5 to rotate. At this time, the tool locking component 10 rotates synchronously, and the tool holder 5 rotates relative to the water cooling component 11. As the tool holder 5 rotates, the CNC tool 7 can rotate circumferentially relative to the tool holder 5. When the corresponding CNC tool 7 rotates to the tool mounting bracket 4 and is located directly behind the tool mounting bracket 4, the tool holder 5 stops rotating and waits for the tool loading process.

[0042] like Figure 1 and Figure 4 as well as Figure 7As shown, the water-cooling assembly 11 includes a water storage pipe 111, which is fixedly connected to the frame 1. A first piston plate 112 is movably connected inside the water storage pipe 111. A first piston rod 113 is fixedly connected to one end of the first piston plate 112 near the limiting plate 101. The first piston rod 113 passes through one end of the water storage pipe 111 and is movably connected to the limiting plate 101. The limiting plate 101 rotates relative to the first piston rod 113. A water inlet valve 114 is fixedly connected to one end of the water storage pipe 111 away from the limiting plate 101. The other end of the water inlet valve 114 is connected to an external water pump.

[0043] Example: During tool loading, an external water pump can be turned on to input high-pressure water into the inlet valve 114. At this time, the high-pressure water enters the water storage pipe 111 and pushes the first piston plate 112 to the left, while simultaneously driving the first piston rod 113 to the left. When the first piston rod 113 moves to the left, it applies pressure to the limiting plate 101. The limiting plate 101 then moves towards the tool holder 5. At this time, the movable rod 105 and the movable plate 106 move to the left and compress the return spring 107. When the return spring 107 is compressed to its limit position, the distance between the limiting plate 101 and the tool holder 5 is at its minimum. At this time, multiple limiting rods 103 are inserted into the limiting holes 8, thus completing the limiting process of all CNC tools 7. At this time, all CNC tools 7 that do not correspond to the tool mounting bracket 4 are limited and cannot move, completing the locking process.

[0044] By utilizing the high-pressure water input from the outside during water cooling, the device can automatically lock unused tools during tool changing and tool installation, preventing tool displacement. The entire process can be completed automatically before tool changing, effectively avoiding the probability of tool collision during tool changing and tool installation in traditional devices, thus reducing safety hazards.

[0045] like Figure 1 and Figure 4 as well as Figure 7 and Figure 8As shown, the tool feed assembly 12 includes a feed tube 121. A first water supply hose 122 is fixedly connected to the rear end of the feed tube 121. The first water supply hose 122 is connected to the outer side of the water storage tube 111 near the left side. When the first piston plate 112 is displaced to the leftmost position of the water storage tube 111, the first piston plate 112 is located to the left of the output end of the first water supply hose 122. A second piston plate 123 is movably sleeved inside the feed tube 121. A second piston rod 124 is fixedly connected to the end of the second piston plate 123 away from the first water supply hose 122. The second piston rod 124 is located away from the second piston... One end of the plate 123 is fixedly connected to a push clamp 127 located behind the limit rod 103. The outer side of the second piston rod 124 is movably sleeved with a limit spring 128. The two ends of the limit spring 128 are connected to one end of the second piston plate 123 and one end of the inner cavity of the push tube 121. A high-pressure nozzle 126 is fixedly connected to the right side of the push clamp 127. The output end of the high-pressure nozzle 126 is located on one side of the tool mounting bracket 4. The rear end of the high-pressure nozzle 126 is fixedly connected to a second water supply hose 125. The other end of the second water supply hose 125 is connected to the outer side of the push tube 121 near the front end.

[0046] When the tool is installed, i.e., when the first piston plate 112 is moved to the leftmost position and the limiting rod 103 is locked with the CNC tool 7, high-pressure water is introduced into the inside of the push tube 121 through the first water supply hose 122, and at the same time, the second piston plate 123 is pushed forward. At this time, the limiting spring 128 can be compressed, and the second piston rod 124 is moved forward. Since the CNC tool 7 and the tool mounting bracket 4 correspond to each other at this time, and the limiting rod 103 has completed the locking process with the CNC tool 7, the push clamp 127 can contact the limiting rod 103 located at the rearmost side and push the limiting rod 103 forward relative to the limiting groove 102. At this time, the CNC tool 7 is moved relative to the groove 6 until the CNC tool 7 is installed into the inside of the tool mounting bracket 4. At this time, the limiting rod 103 is located at the outermost side of the limiting groove 102, and the tool installation process is completed.

[0047] By utilizing externally input high-pressure water, the unused CNC tool 7 can be locked in position while the CNC tool 7 to be used can be directly pushed into the tool mounting bracket 4 and installed. The entire process can be completed automatically after the CNC tool 7 is locked, quickly realizing the tool installation process. At the same time, the CNC tool 7 can also be automatically retracted and the locking of the CNC tool 7 can be automatically released during reset, which significantly improves the tool loading efficiency and the overall tool changing speed.

[0048] Example: After the installation between the CNC tool 7 and the tool mounting bracket 4 is completed, high-pressure water is discharged through the second water supply hose 125. At the same time, the forward displacement of the push clamp 127 can synchronously pull the high-pressure nozzle 126 forward. When the push clamp 127 is in place, the output end of the high-pressure nozzle 126 is also located on one side of the tool mounting bracket 4, that is, at the CNC tool 7 that is installed. At the same time, the high-pressure water discharged through the second water supply hose 125 can be directly sprayed out through the high-pressure nozzle 126 and act on the CNC tool 7 to complete the cooling and debris removal process.

[0049] By directly utilizing the imported high-pressure water and the tool's advancement and installation process, the high-pressure nozzle 126 is automatically adjusted and positioned, and high-pressure water is directly output to cool the CNC tool 7. This avoids the problem of traditional devices requiring adjustment of the high-pressure nozzle 126 position every time the CNC tool 7 is switched. The entire process can be completed automatically, effectively simplifying the operation steps and improving the overall tool changing efficiency.

[0050] Working principle and usage process:

[0051] Before using the device, it can be installed on the corresponding position of the CNC machine tool, and one end of the tool feeding assembly 12 can be connected to the external water pump. High-pressure water is input into the device through the external water pump. At the same time, in the initial state, the tool locking assembly 10 and the water cooling assembly 11 are both in the initial state, and all CNC tools 7 are located inside the slot 6. The tool mounting bracket 4 does not have any tools installed in the initial state.

[0052] When switching tools, the servo motor 2 can be turned on to drive the tool holder 5 to rotate. At this time, the tool locking component 10 rotates synchronously, and the tool holder 5 rotates relative to the water cooling component 11. As the tool holder 5 rotates, the CNC tool 7 can rotate circumferentially relative to the tool holder 5. When the corresponding CNC tool 7 rotates to the tool mounting bracket 4 and is located directly behind the tool mounting bracket 4, the tool holder 5 stops rotating and waits for the tool loading process.

[0053] When loading the tool, an external water pump can be turned on to input high-pressure water into the inlet valve 114. At this time, the high-pressure water enters the water storage pipe 111 and pushes the first piston plate 112 to the left, while driving the first piston rod 113 to the left. When the first piston rod 113 moves to the left, it applies pressure to the limiting plate 101. At this time, the limiting plate 101 moves towards the tool holder 5. At this time, the movable rod 105 and the movable plate 106 move to the left and compress the return spring 107. When the return spring 107 is compressed to the limit position, the distance between the limiting plate 101 and the tool holder 5 is at its minimum. At this time, multiple limiting rods 103 are inserted into the limiting hole 8, thus completing the limiting process of all CNC tools 7. At this time, all CNC tools 7 that do not correspond to the tool mounting bracket 4 are limited and cannot move, thus completing the locking process.

[0054] When the tool is installed, that is, when the first piston plate 112 is moved to the leftmost position and the limiting rod 103 is locked with the CNC tool 7, high-pressure water is introduced into the inside of the push tube 121 through the first water supply hose 122, and at the same time, the second piston plate 123 is pushed forward. At this time, the limiting spring 128 can be compressed, and the second piston rod 124 is moved forward. Since the CNC tool 7 and the tool mounting bracket 4 correspond to each other, and the limiting rod 103 has completed the locking process with the CNC tool 7, the push clamp 127 can contact the limiting rod 103 located at the rearmost side and push the limiting rod 103 to move forward relative to the limiting groove 102. At this time, the CNC tool 7 is moved relative to the groove 6 until the CNC tool 7 is installed into the inside of the tool mounting bracket 4. At this time, the limiting rod 103 can be located at the outermost side of the limiting groove 102, and the tool installation process is completed.

[0055] After the installation between the CNC tool 7 and the tool mounting bracket 4 is completed, high-pressure water is then discharged through the second water supply hose 125. At the same time, the forward displacement of the push clamp 127 can synchronously pull the high-pressure nozzle 126 forward. When the push clamp 127 is in place, the output end of the high-pressure nozzle 126 is also located on one side of the tool mounting bracket 4, that is, at the CNC tool 7 that is installed. At the same time, the high-pressure water discharged through the second water supply hose 125 can be directly sprayed out through the high-pressure nozzle 126 and act on the CNC tool 7 to complete the cooling and debris removal process.

[0056] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
