Description

Technical Field

[0001] The present invention belongs to the technical field of mechanical processing, and in particular relates to a broach integrated storage and transportation rapid exchange system and method. Background Art

[0002] In the field of mechanical processing, broaching is widely used in the processing of various precision parts due to its high precision and high efficiency. As the core tool of broaching, the storage, transportation and replacement efficiency of broaches directly affect production efficiency and processing quality. However, the traditional broaching management model mainly relies on manual operation, which has the following significant drawbacks:

[0003] Low level of automation: In existing technologies, the storage, transportation, and replacement of broaches are mostly performed manually, which is cumbersome and inefficient. Frequent broach replacement, especially in high-variety, low-batch production scenarios, further highlights the limitations of manual operations. For example, broaches are long, slender rods, and manual handling and positioning can easily lead to loss of precision and even damage to the tool.

[0004] Insufficient system integration: Traditional tool magazine structures (such as disc or chain magazines) are difficult to adapt to the unique geometric characteristics of broaches and lack specialized storage and gripping mechanisms for slender rods. Furthermore, existing tool changing systems (such as automatic tool changers in CNC machining centers) typically rely on manipulators and complex transmission structures, making them inadequate for the horizontal transfer and precise positioning of broaches.

[0005] Limited level of intelligence: Manual management can easily lead to problems such as mixed use and wrong installation of tools. It lacks real-time tracking and intelligent scheduling functions for broach parameters and position information, making it difficult to meet the needs of modern flexible production. Summary of the Invention

[0006] The purpose of the present invention is to provide a broach integrated storage and transportation rapid exchange system and method, which significantly improves production efficiency, reduces labor costs, and reduces errors in tool management by automating the storage, transportation and replacement of broaches.

[0007] In a first aspect, the present invention provides a broach integrated storage and transportation rapid exchange system, comprising a storage and positioning mechanism, a tool magazine, and a broach conveying mechanism. The storage and positioning mechanism is located above the broach conveying mechanism and is used to remove broaches from the tool magazine and transfer them to the broach conveying mechanism.

[0008] The broach conveying mechanism includes a tool receiving assembly. The tool receiving assembly includes a rotating support and a holder. The inner end of the holder is rotatably connected to the rotating support and can rotate around a horizontal axis under the drive of a power element. The outer end of the holder is provided with a tool supporting groove. The tool supporting groove is provided with a tool receiving opening. The tool receiving opening is used to receive the broach output by the storage positioning mechanism. The flipping path of the holder passes through the broach clamping position of the broaching machine. One of the side walls of the tool supporting groove is a concave U-shaped groove surface. The U-shaped groove surface supports the broach when the holder flips to the broach clamping position of the broaching machine.

[0009] Preferably, the tool magazine is installed inside a frame-type storage and positioning mechanism and has a multi-layer cantilever support structure.

[0010] Preferably, the storage and positioning mechanism includes a frame structure and two single-sided blade shifting assemblies mounted on either side of the frame structure. The single-sided blade shifting assemblies include a blade removal assembly, a lifting drive assembly, and a transverse drive assembly for driving the blade removal assembly. The blade removal assembly includes a telescopic cylinder and a sleeve driven by the telescopic cylinder. The sleeve is used to cover the end of the broach in the tool magazine.

[0011] Preferably, the single-side knife moving assembly further comprises a lifting mounting beam, which is slidably connected to the frame structure and driven by the lifting drive assembly for lifting movement. The knife removing assembly is slidably connected to the lifting mounting beam and driven by the lateral drive assembly for lateral movement.

[0012] The lift drive assembly includes a lift motor, a lift screw, and lift bearings. The lift screw is vertically mounted and rotatably connected to the frame structure at both ends via lift bearings. The lift motor is mounted on the lift screw to drive its rotation. The two lift drive assemblies are mounted on either end of the same side of the frame structure, respectively, to support and drive the vertical movement of the lift mounting beam.

[0013] The transverse drive assembly includes a synchronous motor, a synchronous belt, synchronous pulleys, and an axle. Two synchronous pulleys are rotatably connected to the ends of the lifting beam via the axle and are synchronously connected via the synchronous belt. The synchronous motor is mounted on the lifting beam and drives one of the synchronous pulleys. The drive direction of the transverse drive assembly is parallel to the Z-axis.

[0014] Preferably, the knife connecting assembly further comprises a lifting cylinder. The rotating support is driven to move up and down by the lifting cylinder. There are two knife connecting assemblies in total. The two knife connecting assemblies can move closer to or farther away from each other.

[0015] Preferably, the broach conveying mechanism further comprises a two-axis horizontal moving assembly. The two-axis horizontal moving assembly comprises a Y-axis moving assembly, an X-axis symmetrical moving assembly and two tool-carrying moving sliders. The X-axis symmetrical moving assembly is mounted on the Y-axis moving assembly. The X-axis symmetrical moving assembly comprises an X-axis motor, an X-axis bidirectional lead screw and an X-axis guide rail. The X-axis bidirectional lead screw is rotatably connected to the X-axis guide rail. The X-axis bidirectional lead screw is driven to rotate by the X-axis motor. Both tool-carrying moving sliders are slidably connected to the X-guide rail, and are connected to the two threaded sections on the X-axis bidirectional lead screw in opposite directions to form a screw pair through nuts. The two tool-carrying assemblies are respectively mounted on the two tool-carrying moving sliders.

[0016] The Y-axis motion assembly includes a Y-axis motor, a Y-axis screw, and a Y-guide rail. The Y-axis screw is rotatably connected to the Y-guide rail and driven by the Y-axis motor. The X-guide rail is slidably connected to the Y-guide rail and forms a screw pair with the Y-axis screw.

[0017] Preferably, the broach conveying mechanism is arranged on one side of the broaching machine.

[0018] Preferably, the side wall of the tool supporting groove facing the U-shaped groove surface is a guiding inclined surface. When the tool receiving opening of the tool supporting groove faces upward, the guiding inclined surface is located on the side of the U-shaped groove surface away from the broaching machine.

[0019] Preferably, the broaching machine includes a broaching machine guide rail, a carriage, and a broach positioning and clamping mechanism. The carriage is slidably connected to the broaching machine guide rail. One of the carriages is driven by a power element. The two broaching machine positioning and clamping mechanisms are mounted on the two carriages, respectively. The broaching machine positioning and clamping mechanism includes a fixed V-block and a movable V-block. By driving the movable V-block to slide laterally, the broach provided by the broaching machine conveying mechanism is clamped between the fixed V-block and the movable V-block.

[0020] In a second aspect, the present invention provides a method for integrated storage, transportation, and rapid exchange of broaches, which utilizes the aforementioned integrated storage, transportation, and rapid exchange system for broaches. The method comprises:

[0021] Select the target broach in the tool magazine.

[0022] The storage and positioning mechanism takes out a target broach from the tool magazine and moves the target broach to just above the holder of the broach conveying mechanism.

[0023] The holder flips over after supporting the target broach, so that the target broach moves to the broaching bed, which clamps the target broach and performs broaching.

[0024] When broaching is finished or the broach needs to be replaced, the broaching machine releases the broach clamped therein. The broach conveying mechanism and the storage and positioning mechanism transfer the broach to the tool magazine.

[0025] The present invention has the following beneficial effects:

[0026] 1. Because broaches are long, slender rods, storage, transportation, and tool changes are inconvenient, and currently, they are largely handled manually. This invention incorporates a multi-layer cantilevered tool magazine, a frame-type storage and positioning mechanism, a telescopic sleeve-type broach end gripper, and a rotary holder. These innovative structures address the technical challenges of automated storage, transportation, and tool changes for long, slender broaches. Consequently, they offer significant economic, social, and environmental benefits.

[0027] 2. The present invention arranges the storage positioning mechanism directly above the broach conveying mechanism, so that the storage positioning mechanism can directly place the broach into the broach supporting groove with the initial opening facing upward, and then by flipping the supporting frame, the broach can be conveniently and quickly placed in the clamping position of the broaching machine.

[0028] 3. The present invention significantly improves the efficiency and accuracy of broach management through automated storage, transportation and tool changing; the intelligent identification and information management functions reduce manual intervention and lower the error rate; the system structure is modular, easy to expand and maintain, and is suitable for multi-variety, small-batch production scenarios.

[0039] The present invention will be further described below with reference to the accompanying drawings.

[0040] Example 1

[0041] The invention discloses a broach integrated storage, transportation and rapid exchange system, which is used to realize efficient storage, transportation and rapid exchange of broaches during the broaching process, thereby improving production efficiency and processing flexibility.

[0042] like Figure 1 As shown, the broach integrated storage and transportation rapid exchange system includes a frame-type storage and positioning mechanism I, a tool magazine II, a broach III, a broaching machine IV, a broach conveying mechanism V, and a control system. The base plate of the broaching machine IV is arranged horizontally, and the broach loading port of the broach positioning and clamping mechanism 24 is positioned upward. The broach conveying mechanism V is arranged on one side of the broaching machine IV. The frame-type storage and positioning mechanism I is located directly above the broach conveying mechanism V. The tool magazine II is installed inside the frame-type storage and positioning mechanism I.

[0043] Tool magazine II utilizes a multi-layer cantilever structure with an opening on one side for horizontally storing multiple broaches III. The opening on the side of tool magazine II allows for the horizontal removal of broaches from the magazine. The frame-type storage and positioning mechanism I is used to remove broaches from tool magazine II and transfer them to the broach conveying mechanism V. The broach conveying mechanism V receives broaches from the frame-type storage and positioning mechanism I and places them into the broach positioning and clamping mechanism 24 of the broaching machine IV.

[0044] A spatial rectangular coordinate system is established with the vertical direction as the Y-axis direction and the broach feed direction as the X-axis direction. The broach feed mechanism V and the broaching machine IV are arranged along the Z-axis direction.

[0045] like Figure 2 、 3 As shown in Figure 4, the storage positioning mechanism I includes a frame structure and two single-side blade shifting assemblies respectively installed on both sides of the frame structure. The frame structure includes an upper beam 8, a lower beam 9 and a column 11 fixed into a rectangular frame.

[0046] The single-sided knife moving assembly includes a lifting mounting beam 4, a knife removing assembly, two lifting drive assemblies, and a transverse drive assembly. The column 11 of the frame structure adopts a lifting dovetail track structure. The two ends of the lifting mounting beam 4 are respectively slidably connected to the two lifting dovetail track structures on the same side of the frame structure. The lifting mounting beam 4 is driven by two lifting drive assemblies to perform lifting movement. The lifting mounting beam 4 adopts a transverse dovetail track structure. The knife removing assembly is slidably connected to the transverse dovetail track structure and is driven by the transverse drive assembly to perform transverse movement.

[0047] The lift drive assembly includes a lift motor 1, a lift screw 3, and a lift bearing 2. The lift screw 3 is vertically mounted, with both ends rotatably connected to the frame structure via the lift bearings 2. The lift motor 1 is mounted on the lift screw 3 to drive its rotation. The two lift drive assemblies are mounted on either end of the same side of the frame structure, respectively, to support and drive the vertical movement of the two ends of the lift mounting beam 4.

[0048] The transverse drive assembly includes a synchronous motor 13, a synchronous belt 7, synchronous pulleys 10, and an axle 14. Two synchronous pulleys 10 are rotatably connected to the ends of the lifting beam 4 via the axle 14 and are synchronously connected via the synchronous belt 7. The synchronous motor 13 is mounted on the lifting beam 4 and is used to drive one of the synchronous pulleys 10. The driving direction of the transverse drive assembly is parallel to the Z-axis.

[0049] The tool removal assembly includes a tool removal head 5, a telescopic cylinder 6, and a sleeve 12. The tool removal head 5 is slidably connected to the lifting mounting beam 4 via a slider and is fixed to the synchronous belt 7. The cylinder body of the telescopic cylinder 6 is fixed to the tool removal head 5, and the piston rod is horizontally facing the tool magazine II. The sleeve 12 is fixed to the end of the piston rod of the telescopic cylinder 6. The end opening of the sleeve 12 is horizontally facing the tool magazine II. The telescopic direction of the telescopic cylinder 6 is parallel to the X-axis direction.

[0050] The axis of the broach III placed in tool magazine II is parallel to the axis of the sleeve 12. The end openings of the sleeves 12 in the two single-sided tool transfer assemblies are aligned, respectively used to fit over the ends of the broaches, facilitating lifting and laterally removing the broaches from tool magazine II. After removing the broaches, the single-sided tool transfer assembly moves them downward to the bottom of the frame structure and transfers them to the broach conveyor mechanism V.

[0051] The broach conveying mechanism V includes a support member 30, a two-axis horizontal moving assembly and two tool receiving assemblies. The two-axis horizontal moving assembly includes two Y-direction moving assemblies, an X-direction symmetrical moving assembly and two tool-carrying moving slides 26. The Y-direction moving assembly includes a Y-direction motor 29, a Y-axis screw 27 and a Y-direction guide rail 28. The Y-direction guide rails 28 in the two Y-direction moving assemblies are both fixed to the support member 30. The Y-axis screw 27 is rotatably connected to the Y-direction guide rail 28 and is driven to rotate by the Y-direction motor 29.

[0052] The X-axis symmetrical movement assembly includes an X-axis motor 35, an X-axis bidirectional screw 33, an X-axis guide rail 34, an X-axis support 25, and an X-axis bearing 37. The bottom ends of the X-axis guide rail 34 are slidably connected to the Y-axis guide rail 28 and form a screw pair with the two Y-axis screws 27 via nuts. X-axis support 25 is fixed to each end of the X-axis guide rail 34. The ends of the X-axis bidirectional screw 33 are rotatably connected to the two X-axis support 25 via X-axis bearings 37. The X-axis bidirectional screw 33 is driven for rotation by the X-axis motor 35. The two tool-holding sliders 26 are slidably connected to the X-axis guide rail 34. The two tool-holding sliders 26 form a screw pair with the two oppositely threaded sections of the X-axis bidirectional screw 33 via nuts. Two tool-receiving assemblies are mounted on the two tool-holding sliders 26. Rotation of the X-axis bidirectional screw 33 can drive the two tool-receiving assemblies toward or away from each other to facilitate the handling of broaches of different lengths.

[0053] The tool receiving assembly includes a rotary motor 36, a lifting cylinder 32, and a support 31. The lifting cylinder 32 is vertically mounted, with the cylinder body fixed to the tool holding slide 26. A rotating support is located at the top of the lifting push rod of the lifting cylinder 32. The support 31 is elongated, with its inner end pivotally connected to the rotating support via a rotating shaft. The rotary motor 36 is mounted on the rotating support and is used to drive the support 31 to rotate about the X-axis.

[0054] The outer end of the support 31 is provided with a tool support groove. The tool support groove is provided with a tool receiving opening. The direction of the tool receiving opening is consistent with the length of the support 31. The two side walls of the tool support groove are respectively an outward-turned guide slope and an inward-concave U-shaped groove surface. When the tool receiving opening of the tool support groove is facing straight up, the U-shaped groove surface is located on the side of the guide slope closer to the broaching machine IV.

[0055] The tool receiving opening is used to receive the broach. The guiding slope is used to expand the tool receiving opening and guide the broach. The U-shaped groove surface is used to provide support and restraint for the broach when the holder 31 is flipped 90°, ensuring that the broach can smoothly enter the broach positioning and clamping mechanism 24 of the broaching machine IV.

[0056] During the operation, the control system transports the designated broach III to the exit of the tool magazine II according to the position of the broach III in the tool magazine II, and connects it to the holder 31 of the tool receiving assembly of the broach conveying mechanism V. Then the broach conveying mechanism V transports the broach III to the side of the broaching bed IV and places the broach III into the broach positioning and clamping mechanism 24.

[0057] In the tool connecting assembly, the lifting cylinder 32 is used to adjust the height of the broach III supported by the holder 31, and the rotating motor 36 is used to drive the holder 31 to rotate and place the broach III into the broach positioning and clamping mechanism 24.

[0058] The broaching machine IV comprises a base, a feed drive motor 20, a feed bearing 21, a broaching guide rail 22, a broaching screw 23, a carriage 38, and a broach positioning and clamping mechanism 24. The broaching guide rail 22 is fixed to the base. Both carriages 38 are slidably connected to the broaching guide rail 22. One end of the broaching screw 23 is rotatably connected to the base via the feed bearing 21. The feed drive motor 20 is used to drive the broaching screw 23 in rotation. One of the carriages 38 and the broaching screw 23 form a screw pair via a nut.

[0059] The two broach positioning and clamping mechanisms 24 are mounted on two carriages 38, respectively. The broach positioning and clamping mechanisms 24 include a clamping guide rail 24-1, a fixed V-block 24-2, a movable V-block 24-3, a clamping screw 24-4, a clamping bearing 24-5, a clamping support 24-6, and a clamping motor 24-7. The clamping guide rail 24-1 and the fixed V-block 24-2 are fixed to their respective carriages 38. The movable V-block 24-3 is slidably connected to the clamping guide rail 24-1. The clamping screw 24-4 is rotationally connected to its corresponding carriage 38 via the clamping bearing 24-5 and the clamping support 24-6. The clamping screw 24-4 and the movable V-block 24-3 form a screw pair. The clamping motor 24-7 is used to drive the clamping screw 24-4 to rotate. The V-grooves on the fixed V-block 24-2 and the movable V-block 24-3 face each other.

[0060] When the ends of broach III are placed in the two broach positioning and clamping mechanisms 24 of the broaching machine, the clamping motor 24-7 drives the movable V-block 24-3 via the clamping screw 24-4, clamping broach III between the fixed V-block 24-2 and the movable V-block 24-3. The feed drive motor 20 drives the carriages 38 at both ends of the broaching machine to reciprocate linearly via the broaching screw 23, thereby achieving the broaching operation of broach III.

[0061] like Figure 9The control system primarily implements position control, completing three major tasks: tool magazine storage, broach transport, and tool change on the broaching machine. The control system includes a servo drive, position sensors, an optimization controller, and pneumatic valves, which are used to control the motors (specifically, servo motors) and cylinders in each mechanism. Based on the position of broach III in tool magazine II, broach III is transported from tool magazine II to the broach positioning and clamping mechanism 24. After broaching is completed, broach III is transported from the broach positioning and clamping mechanism 24 to a designated position in tool magazine II. Multiple position sensors detect the positions of different moving structures, enabling precise control.

[0062] In this embodiment, each motor and the structure it drives to rotate can be directly fixedly connected or indirectly connected via a transmission structure, which includes a gear transmission structure, a belt transmission structure, or other existing power transmission devices.

[0063] In this embodiment, the guide rails are all dovetail guide rails; in some other embodiments, the guide rails may also adopt other existing guide structures.

[0064] Example 2

[0065] A broach integrated storage and transportation rapid exchange method using the broach integrated storage and transportation rapid exchange system provided in Example 1

[0066] The broach integrated storage and transportation rapid exchange method comprises the following steps:

[0067] Step 1: Various broaches III are placed in rows and columns in tool magazine II. The parameters and position information for broach III are stored in a corresponding data table structure in the control system and mapped to the CNC system of broaching machine IV. Based on the specific workpiece broaching requirements, the appropriate broach III is selected, and the specific position code of the target broach III is provided to the control system, which then sends a command to the storage and positioning mechanism I.

[0068] Step 2: Storage and Positioning Mechanism I synchronizes and controls the four lift drive assemblies within the frame structure, based on instructions from the control system. First, the lift drive assemblies drive the left and right lateral drive assemblies and the tool removal assembly to determine their position in the Y direction (i.e., vertical direction). The lateral drive assemblies then move the tool removal assembly along the Z direction to the target broach storage location, aligning the sleeves 12 in the two tool removal assemblies within Tool Magazine II with the ends of the target broach.

[0069] Step three: the telescopic cylinder 6 in the two tool-picking assemblies is actuated to extend the sleeve 12 and cover the end of the target broach III; the target broach III is lifted by the lifting drive assembly and the transverse drive assembly, and the target broach III is moved out of the tool magazine II and then moved to the top of the holder 31 of the broach conveying mechanism V.

[0070] Step 4: The X-axis symmetrical moving component in the broach conveying mechanism V adjusts the distance between the two tool receiving components; the lifting cylinder 32 drives the holder 31 to rise and hold the end of the target broach III; the Y-axis moving component conveys the target broach III to the side of the broaching machine IV.

[0071] Step 5: The rotary motor 36 in the tool receiving assembly drives the holder 31 to flip over, and the end of the target broach III is placed into the broach positioning and clamping mechanism 24. The broach positioning and clamping mechanism 24 clamps the target broach III.

[0072] Step 6: The broaching machine IV uses the target broach III to broach the workpiece. After the broaching is completed, the broach III is placed back into the tool magazine II in the reverse order.
