Description

Technical Field

[0001] This application relates to the field of Swiss-type lathe tool holder technology, and in particular to a tool holder structure for improving the efficiency of Swiss-type lathes and its usage method. Background Technology

[0002] The Swiss-type lathe, also known as a Swiss-type CNC lathe, is a type of precision machining equipment. By assembling multiple cutting tools, it can simultaneously complete composite machining processes such as turning, milling, drilling, boring, tapping, and engraving. It is mainly used for the batch processing of non-standard parts such as precision hardware.

[0003] Regarding the aforementioned technologies, the tool holders of Swiss-type lathes are typically fixed to the internal frame of the lathe using screws. The tool holders are then removed and replaced by turning the screws. However, the overall tool changing speed is too slow, which reduces the working efficiency of the Swiss-type lathe and therefore needs to be improved. Summary of the Invention

[0004] To address the problem of slow tool change speed affecting the working efficiency of Swiss-type lathes, this application provides a tool holder structure and its usage method for improving the efficiency of Swiss-type lathes.

[0005] Firstly, the tool holder structure for improving the efficiency of a Swiss-type lathe provided in this application adopts the following technical solution: A tool holder structure for improving the efficiency of a Swiss-type lathe includes a frame and several sets of mounting seats slidably disposed on the frame, the mounting seats being used to mount cutting tools; the frame is provided with a moving component for driving the mounting seats to move, and the frame is provided with a locking component for restricting the movement of the mounting seats.

[0006] By adopting the above technical solution, when it is necessary to change the tool, the locking component releases the locking of the mounting seat of the tool to be replaced, and the moving component drives the mounting seat of the tool to be replaced to gradually move away from the machining area of ​​the Swiss-type lathe, so as to facilitate the convenient replacement of the tool on the mounting seat. Then, the moving component is used to reset the mounting seat after the tool replacement, and the locking component is used to conveniently lock the mounting seat after the tool replacement. The whole process reduces the phenomenon of manual intervention in the operation and machining of the Swiss-type lathe, realizes rapid tool holder replacement, and improves the working efficiency of the Swiss-type lathe.

[0007] Preferably, the moving component includes a moving lead screw, a moving guide rod, and a moving motor; the moving lead screw is rotatably mounted on the frame, the moving guide rod is mounted on the frame, and the length directions of the moving lead screw and the moving guide rod are parallel to each other; both the moving lead screw and the moving guide rod pass through the mounting base, and the moving lead screw is threadedly connected to the mounting base; the moving motor is mounted on the frame to drive the moving lead screw to rotate.

[0008] By adopting the above technical solution, the output end of the moving motor drives the moving lead screw to rotate, the rotating moving lead screw drives the mounting base, and the moving guide rod guides the moving path of the mounting base, so as to achieve the purpose of driving any mounting base to move independently.

[0009] Preferably, the locking assembly includes a fixing frame, an electromagnetic component, and a control component; the fixing frame is mounted on the frame, the electromagnetic component is mounted on the fixing frame, and each electromagnetic component is correspondingly mounted to a mounting base, with each electromagnetic component used to electromagnetically attract a corresponding mounting base; the control component is mounted on the frame, and all electromagnetic components are controlled by the control component, which is used to control the power supply to any electromagnetic component.

[0010] By adopting the above technical solution, the fixing frame sets the electromagnetic components with each set of mounting seats, and the control component controls the on and off of any electromagnetic component to quickly switch the magnetic locking state of the electromagnetic component to the mounting seat.

[0011] Preferably, the locking assembly further includes a locking rod, an adsorption element, an anti-detachment block, and a reset element; the locking rod is slidably mounted on the fixing frame and is located on the side of each set of electromagnetic elements; the adsorption element is located on the locking rod and is magnetically attracted to the electromagnetic elements; the mounting base has a locking groove for the locking rod to abut; the anti-detachment block is located at the end of the locking rod away from the mounting base to prevent the locking rod from detaching from the fixing frame; the reset element is located between the adsorption element and the fixing frame to drive the adsorption element to reset through its own pulling force.

[0012] By adopting the above technical solution, when the electromagnetic component is energized and generates magnetism to magnetically lock the mounting base, the electromagnetic component attracts the adsorption component, causing the adsorption component to drive the locking rod to gradually approach the mounting base, and causing the reset component to deform and stretch. The locking rod slides into the locking groove to lock and limit the position of the mounting base. When the electromagnetic component is de-energized, it cancels the magnetic attraction to the mounting base and the adsorption component. The reset component gradually recovers its deformation and drives the adsorption component and locking rod away from the mounting base through its own pulling force, causing the locking rod to disengage from the locking groove, thereby facilitating the movement of the mounting base. By utilizing the magnetic driving force of the tension and magnetic components through their switching on and off states, the locking rod automatically locks and disengages from the mounting base, further improving the locking and limiting effect on the mounting base.

[0013] Preferably, a positioning component is provided between the mounting base and the cutting tool to position the cutting tool on the mounting base; a fastening component is provided between the mounting base and the cutting tool to securely connect the mounting base and the cutting tool.

[0014] By adopting the above technical solution, the positioning component quickly positions the tool on the mounting base, so as to facilitate convenient assembly and disassembly of the mounting base and the tool; the fastening component fixes the tool on the mounting base, realizing a tight connection between the tool and the mounting base.

[0015] Preferably, the positioning component includes a base, a positioning block, and a magnetic block; the base is disposed on the side wall of the tool facing the mounting base, the positioning block is disposed on the side wall of the base facing the mounting base, and the side wall of the mounting base facing the tool has a positioning groove for the positioning block to abut; the magnetic block is disposed inside the positioning groove for magnetically adsorbing the positioning block.

[0016] By adopting the above technical solution, the positioning block is inserted into the positioning groove, and the magnetic attraction between the positioning block and the magnetic block is used to achieve rapid positioning of the tool, so that the fastening assembly can fasten the tool and the mounting base. In addition, when the fastening assembly cancels the fastening connection between the tool and the mounting base, the magnetic attraction between the positioning block and the magnetic block ensures a stable connection between the tool and the mounting base, reducing the risk of the tool accidentally falling off.

[0017] Preferably, the fastening assembly includes a rotating frame, a fastening rod, a drive rod, and a drive component; the rotating frame is rotatably mounted on the side wall of the mounting base, the fastening rod is located at the end of the rotating frame facing the tool, and the side wall of the base has a fastening groove for the fastening rod to abut; the drive rod is rotatably mounted at the end of the rotating frame away from the fastening rod, the drive component is mounted on the mounting base, and the output end of the drive component is rotatably connected to the end of the drive rod away from the rotating frame, so as to drive the drive rod closer to or away from the tool.

[0018] By adopting the above technical solution, the output end of the drive component drives the drive rod to approach or move away from the base, so that the rotating frame drives the fastening rod to rotate in the direction of approaching or moving away from the base. The rotation of the fastening rod abuts into the fastening groove, thus realizing a fast, convenient, precise and stable connection between the tool and the mounting base.

[0019] Preferably, the frame is provided with a storage cavity for storing lubricating oil, the interior of the storage cavity is connected to the end of the moving lead screw, the frame is provided with an oil injection hole that communicates with the interior of the storage cavity, and the frame is provided with a sealing plug for sealing the oil injection hole.

[0021] Preferably, the storage cavity is provided with an oil-absorbing strip for immersing in lubricating oil.

[0022] By adopting the above technical solution, the oil suction strip absorbs the lubricating oil inside the storage cavity, reducing the phenomenon of rapid loss of lubricating oil inside the storage cavity, ensuring the service life of the lubricating oil inside the storage cavity, and reducing the tediousness of workers frequently adding lubricating oil.

[0023] Secondly, This application provides a method for using a tool holder structure to improve the efficiency of a Swiss-type lathe, comprising the following steps: Unlock: The locking assembly releases the lock on the mounting base containing the tool to be replaced; Replacement: The moving component moves the mounting base and the tool to be replaced synchronously, moves the tool holder to be replaced out of the Swiss-type lathe machining area, replaces the tool, and then the moving component moves the replaced tool and the mounting base back to their original positions. Locking: The locking assembly locks and secures the mounting base of the replaced tool.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1.

The moving motor 23 is mounted on the frame 1, and the output end of the moving motor 23 is drivenly connected to the end of the moving lead screw 21 to drive the moving lead screw 21 to rotate.

[0034] Reference Figure 2 and Figure 3The locking assembly 3 includes a fixing frame 31, an electromagnetic component 32, a control component 33, a locking rod 34, an adsorption component 35, an anti-detachment block 36, and a reset component 37.

The fixing frame 31 is welded and fixed to the side wall of the frame 1 away from the mounting base 11. The electromagnetic component 32 is fixedly installed on the side wall of the fixing frame 31 facing the mounting base 11. The electromagnetic component 32 corresponds one-to-one with the mounting base 11. Each set of electromagnetic components 32 is in contact with the corresponding mounting base 11, so that each electromagnetic component 32 electromagnetically attracts the corresponding mounting base 11.

[0035] Reference Figure 2 and Figure 3 The control component 33 is fixedly installed on the frame 1. All electromagnetic components 32 are electrically connected to the control component 33. The control component 33 is used to control the on and off of any electromagnetic component 32, thereby controlling the magnetic attraction state of any electromagnetic component 32 to the mounting base 11.

[0036] Reference Figure 2 and Figure 3 The locking rod 34 is slidably inserted into the fixing frame 31, and the locking rod 34 is distributed on both sides of each group of electromagnetic components 32. The adsorption component 35 is fixedly sleeved on the end of the locking rod 34 facing the mounting base 11. The adsorption component 35 and the electromagnetic component 32 are magnetically attracted, and the adsorption component 35 is located on the side of the electromagnetic component 32 away from the mounting base 11, so as to drive the locking rod 34 to move towards the mounting base 11. The side wall of the mounting base 11 facing the fixing frame 31 is provided with locking grooves 112 so that the end of the locking rod 34 away from the fixing frame 31 can slide into it.

[0037] Reference Figure 2 and Figure 3 The anti-detachment block 36 is integrally formed on the end of the locking rod 34 away from the mounting base 11, and the side wall of the anti-detachment block 36 facing the mounting base 11 can abut against the side wall of the fixing frame 31 away from the mounting base 11 to limit the locking rod 34 from sliding off the fixing frame 31. The reset member 37 is sleeved on each set of locking rods 34 and is located between the fixing frame 31 and the adsorption member 35. One end of the reset member 37 is glued to the side wall of the fixing frame 31 facing the adsorption member 35, and the other end of the reset member 37 is glued to the side wall of the adsorption member 35 away from the mounting base 11, so that the pull force of the reset member 37 itself drives the adsorption member 35 to move the locking rod 34 away from the mounting base 11, and causes the locking rod 34 to disengage from the locking groove 112.

[0038] Reference Figure 1 and Figure 3A positioning component 4 is installed between each set of mounting base 11 and cutting tool 12 to quickly position the cutting tool 12 on the mounting base 11. A fastening component 5 is installed between the mounting base 11 and the cutting tool 12 to securely connect the mounting base 11 and the cutting tool 12.

[0039] Reference Figure 1 and Figure 3 The positioning component 4 includes a base 41, a positioning block 42, and a magnetic block 43. The base 41 is fixedly connected to the side wall of the cutter 12 facing the mounting base 11. The positioning block 42 is integrally formed on the side wall of the base 41 facing the mounting base 11. The side wall of the mounting base 11 facing the cutter 12 has a positioning groove 111 for the positioning block 42 to slide into. In this embodiment, the positioning block 42 may be made of iron, and the magnetic block 43 may be made of magnet. The magnetic block 43 is glued to the bottom of each set of positioning grooves 111 to magnetically attract the positioning block 42.

[0040] Reference Figure 1 and Figure 3 The fastening assembly 5 is installed on both sides of each set of mounting bases 11. The fastening assembly 5 includes a rotating frame 51, a fastening rod 52, a drive rod 53, and a drive component 54. In this embodiment, the drive component 54 can be a drive cylinder. The rotating frame 51 is rotatably connected to the side wall of the mounting base 11 via a rotating shaft 50. The fastening rod 52 is integrally formed on the end of the rotating frame 51 facing the tool 12, and the fastening rod 52 is located on the side wall of the rotating frame 51 facing the tool 12. The base 41 has a fastening groove 411 on the side wall facing the rotating frame 51, so that the end of the fastening rod 52 away from the rotating frame 51 can rotate and abut against it. In this embodiment, an elastic plug for sealing the fastening groove 411 is glued to the end of the fastening rod 52 away from the rotating frame 51. The elastic plug can be made of rubber.

[0041] Reference Figure 1 and Figure 3 The drive rod 53 is rotatably connected to the end of the rotating frame 51 away from the fastening rod 52. The drive member 54 is fixedly connected to the side wall of the mounting base 11 through the support plate. The output end of the drive member 54 is rotatably connected to the end of the drive rod 53 away from the rotating frame 51. Through the extension and retraction movement of the output end of the drive member 54, the drive rod 53 is driven towards or away from the base 41, thereby causing the rotating frame 51 to drive the fastening rod 52 to rotate around the rotating shaft 50, so that the fastening rod 52 approaches or moves away from the base 41.

[0042] Reference Figure 1 and Figure 4The top of the frame 1 has an internal storage cavity 13 for storing lubricating oil. A cotton oil-absorbing strip 131 is placed inside the storage cavity 13 to soak and store the lubricating oil. An oil filling hole 14 is provided through the frame 1 and communicates with the inside of the storage cavity 13 to supply lubricating oil. A rubber sealing plug 141 is installed at the oil filling hole 14 to seal it. The ends of the moving lead screw 21 and the moving guide rod 22 facing the sealing plug 141 are located inside the storage cavity 13, so that the lubricating oil inside the storage cavity 13 can lubricate the moving lead screw 21 and the moving guide rod 22.

[0043] The implementation principle of the tool holder structure for improving the efficiency of a Swiss-type lathe according to the embodiments of this application is as follows: When it is necessary to change the tool 12, the control component 33 controls the electromagnetic component 32 of the corresponding tool 12 and mounting base 11 to be de-energized, so that the electromagnetic component 32 contacts the magnetic constraint force on the mounting base 11; the control component 33 controls the start of the moving motor 23 corresponding to the mounting base 11, so that the moving screw 21 rotates and drives the mounting base 11 to move the tool 12 away from the machining area of ​​the Swiss-type lathe quickly.

[0044] The output end of the control drive 54 retracts, causing the drive rod 53 to rotate the rotating frame 51 and the fastening rod 52 in a direction away from the base 41. This causes the fastening rod 52 to gradually disengage from the fastening groove 411 and contact the fastening assembly 5 to fasten the mounting base 11 and the tool 12. This makes it easier for the operator to disassemble and place the new tool 12 on the mounting base 11. The positioning block 42 and the magnetic block 43 attract each other magnetically to quickly position the new tool 12 on the mounting base 11.

[0045] The output end of the control drive 54 extends, causing the drive rod 53 to drive the rotating frame 51 and the fastening rod 52 to rotate toward the base 41, so that the fastening rod 52 gradually abuts into the fastening groove 411, thus fastening the new tool 12 to the mounting base 11.

[0046] The output of the control motor 23 drives the lead screw 21 to rotate, causing the mounting base 11 to align the new tool 12 with the corresponding electromagnetic component 32. The control component 33 then energizes the corresponding electromagnetic component 32 to electromagnetically attract the mounting base 11 and the new tool 12, thus locking their positions. This process reduces manual intervention in the Swiss-type lathe operation, enables rapid tool holder changes, and improves the lathe's working efficiency.

[0047] This application also discloses a method for using a tool holder structure to improve the efficiency of a Swiss-type lathe, including the following steps: Unlock: Locking component 3 releases the lock on the mounting base 11 on which the tool to be replaced 12 is installed; Replacement: The moving component 2 moves the mounting base 11 and the tool to be replaced 12 synchronously, moves the tool holder to be replaced out of the Swiss-type lathe machining area, replaces the tool 12, and then the moving component 2 moves the replaced tool 12 and the mounting base 11 back to their original positions. Locking: The locking assembly 3 locks and secures the mounting base 11 of the replaced tool 12.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
