Description

Technical Field

[0001] This invention relates to the field of metal cutting machine tools, specifically a flip-top enclosed straight-line tool magazine. Background Technology

[0002] Currently, users in the metal cutting field generally require automation to reduce human operation time. Automatic tool change has become a standard configuration for machine tools. Traditional linear tool magazines are basically open or semi-enclosed. These types of tool magazines are usually installed in the machining area, where there are a lot of waste chips and cutting fluid. These chips often easily enter the linear tool magazine, causing waste chip accumulation inside the tool magazine and on the tool holder. This can easily lead to tool change jamming failure. Long-term use can also cause severe corrosion to the tool holder. The waste chips on the tool are stuck on the inner cone surface of the spindle after tool change, causing damage to the inner cone surface of the spindle. The tool and spindle cannot make good contact, resulting in poor workpiece quality. Summary of the Invention

[0003] The purpose of this invention is to solve the above-mentioned problems and provide a flip-top enclosed linear tool magazine that encloses the entire linear tool magazine inside the sheet metal, preventing waste chips and cutting fluid from entering the tool magazine area and ensuring that the tools can make good contact with the spindle.

[0004] The technical solution adopted by this invention to solve its technical problem is:

[0005] A flip-top enclosed straight-line tool magazine includes a housing, a cover plate disposed on the upper end of the housing and flipped on the upper end of the housing, and a movable plate disposed inside the housing for supporting a tool support frame. The housing is provided with a movable frame that moves inside the housing. The movable plate is disposed on the movable frame and moves up and down on the movable frame. When the cover plate rotates, it drives the movable frame to move through a linkage mechanism.

[0006] The linkage mechanism includes a drive rod fixed to the rear end of the cover plate, a rotating rod disposed at the bottom of the box and rotatably connected to the inner wall of the box at the middle position, and a connecting rod connecting the rear end of the drive rod and the rear end of the rotating rod. The rear end of the moving frame is provided with a guide plate, the guide plate is provided with a first guide hole, and the front end of the rotating rod is provided with a first guide rod that cooperates with the first guide hole.

[0007] The box body has a second guide hole on both sides. The second guide hole includes a horizontal part on the left end and an arc-shaped part on the right end of the horizontal part. The arc-shaped part is curved upward. The moving plate has a second guide rod at both ends that cooperates with the second guide hole.

[0008] Furthermore, cylinders for driving the cover plate to flip are provided on both sides of the box body.

[0009] Furthermore, a transparent acrylic panel is provided on the front side of the box.

[0010] Furthermore, the rear end of the housing is provided with nozzles that correspond one-to-one with the tool support frame.

[0011] Furthermore, the bottom of the housing is provided with a tool magazine base, and the bottom of the movable frame is slidably connected to the tool magazine base via a guide rail slider pair.

[0012] Furthermore, a support shaft is provided at the middle position of the rotating rod, and both ends of the support shaft are rotatably connected to the inner wall of the box.

[0013] Furthermore, the movable plate and the movable frame are slidably connected via a guide rail slider pair.

[0014] The beneficial effects of this invention are:

[0015] 1. This invention includes a housing, a cover plate disposed on the upper end of the housing and flipping upside down, and a movable plate disposed inside the housing for supporting a tool support frame. The housing contains a movable frame that moves within the housing. The movable plate is mounted on the movable frame and moves up and down on it. When the cover plate rotates, it drives the movable frame to move via a linkage mechanism. During tool changing, when there is no tool on the machine tool spindle, the cover plate flips open. Under the action of the linkage mechanism, the movable frame moves forward, and the movable plate moves upward, pushing the tool upward to a designated position, facilitating tool removal from the machine tool spindle. Afterward, the cover plate closes, and the movable frame and movable plate retract, sealing the entire linear tool magazine inside the housing. This prevents waste chips and cutting fluid from entering the tool magazine area, eliminates waste chips on the tool holder, prevents automatic tool changing jamming, avoids damage to the inner tapered surface of the spindle, ensures good contact between the tool and the spindle, and guarantees precise workpiece machining quality.

[0016] 2. The linkage mechanism in this invention includes a drive rod fixed to the rear end of the cover plate, a rotating rod disposed at the bottom of the box and rotatably connected to the inner wall of the box at the middle position, and a connecting rod connecting the rear end of the drive rod and the rear end of the rotating rod. The rear end of the movable frame is provided with a guide plate, the guide plate is provided with a first guide hole, and the front end of the rotating rod is provided with a first guide rod that cooperates with the first guide hole. When the cover plate is opened, the drive rod swings downward, and under the action of the connecting rod, the rotating rod rotates counterclockwise. Under the action of the first guide rod and the first guide hole, the movable frame moves forward. The mechanical mechanism realizes the linkage between the opening of the cover plate and the movement of the movable frame. The structure is simple, does not require a separate drive mechanism, has low cost, good reliability, and a compact cycle.

[0017] 3. This invention provides second guide holes on both side walls of the housing. Each second guide hole includes a horizontal portion at the left end and an arc-shaped portion at the right end of the horizontal portion, the arc-shaped portion curving upwards. Both ends of the movable plate are provided with second guide rods that mate with the second guide holes. When the movable frame moves back and forth, the second guide rods move along the second guide holes. When the second guide rods reach the arc-shaped portion, the movable plate rises, and the tool support frame rises from the housing, pushing the tool upwards to a designated position. Under the action of the second guide holes and second guide rods, the movement of the movable frame and the lifting and lowering of the movable plate are linked, resulting in a simple structure, low cost, and high reliability.

[0027] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this invention.

[0028] like Figure 1 , Figure 2 and Figure 5 As shown, a flip-top enclosed straight-row tool magazine includes a housing 1, a cover 2 disposed on the upper end of the housing 1 and flipped at the upper end of the housing 1, and a movable plate 3 disposed inside the housing 1 for supporting tool support frames 4. Several tool support frames are disposed on the upper end of the movable plate 3 and arranged side by side. The housing 1 is provided with a movable frame 5 that moves within the housing 1. The movable plate 3 is disposed on the movable frame 5 and moves up and down on the movable frame 5. When the cover 2 rotates, it drives the movable frame 5 to move through a linkage mechanism. During tool changing: at this time there is no tool on the machine tool spindle, the cover 2 flips open, and under the action of the linkage mechanism, the movable frame 5 moves forward and the movable plate 3 moves upward, pushing the tool upward to a designated position, so that the machine tool spindle can remove the tool. Afterwards, cover plate 2 is closed, and moving frame 5 and moving plate 3 retract, sealing the entire straight-line tool magazine inside the housing 1. This prevents waste chips and cutting fluid from entering the tool magazine area, eliminates waste chips on the tool holder, prevents automatic tool changing and tool jamming failures, and avoids damage to the inner tapered surface of the spindle. The tool and spindle can make good contact, resulting in precise workpiece machining quality.

[0029] like Figure 6 and Figure 7 As shown, the linkage mechanism includes a drive rod 7 fixed to the rear end of the cover plate 2, a rotating rod 8 located at the bottom of the box 1 and rotatably connected to the inner wall of the box 1 at its middle position, and a connecting rod 9 connecting the rear end of the drive rod 7 and the rear end of the rotating rod 8. The upper end of the connecting rod 9 is rotatably connected to the rear end of the drive rod 7, and the lower end of the connecting rod 9 is rotatably connected to the rear end of the rotating rod 8. The rear end of the moving frame 5 is provided with a guide plate 10, and the guide plate 10 is provided with a first guide hole 11. The front end of the rotating rod 8 is provided with a first guide rod 12 that cooperates with the first guide hole 11. When the cover plate 2 is opened, the drive rod 7 swings downward. Under the action of the connecting rod 9, the rotating rod 8 rotates counterclockwise. Under the action of the first guide rod 12 and the first guide hole 11, the moving frame 5 moves forward. The mechanical mechanism realizes the linkage between the opening of the cover plate 2 and the movement of the moving frame 5. The structure is simple, does not require a separate drive mechanism, has low cost, good reliability, and a compact cycle.

[0030] like Figure 1 and Figure 5As shown, the box body 1 has second guide holes 17 on both side walls. Each second guide hole 17 includes a horizontal portion on the left and an arc-shaped portion on the right, the arc-shaped portion curving upwards. The movable plate 3 has second guide rods 18 at both ends that mate with the second guide holes 17. When the movable frame 5 moves back and forth, the second guide rods 18 move along the second guide holes 17. When the second guide rods 18 reach the arc-shaped portion, the movable plate 3 rises, and the tool support frame 4 rises from the box body, pushing the tool upwards to a designated position. Under the action of the second guide holes 17 and the second guide rods 18, the movement of the movable frame 5 and the lifting and lowering of the movable plate 3 are linked, resulting in a simple structure, low cost, and high reliability.

[0031] like Figure 1 As shown, cylinders 13 are provided on both sides of the box 1 to drive the cover plate 2 to flip. The cover plate 2 is driven to flip by the extension and retraction of the piston rod of the cylinder 13.

[0032] like Figure 1 As shown, a transparent acrylic plate 14 is provided on the front side of the box 1 to facilitate observation of the blades inside the box.

[0033] like Figure 1 As shown, the rear end of the housing 1 is equipped with a nozzle 15 corresponding to the tool support frame 4, which is connected to an air source via an air pipe and has a solenoid valve. The nozzle 15 blows air onto the tool handle to keep it clean.

[0034] like Figure 3 and Figure 4 As shown, the bottom of the housing 1 is provided with a tool magazine base 6, and the movable frame 5 is L-shaped when viewed from the side. The bottom of the movable frame 5 is slidably connected to the tool magazine base 6 through a guide rail slider pair.

[0035] like Figure 6 As shown, a support shaft 16 is fixedly provided at the middle position of the rotating rod 8, and both ends of the support shaft 16 are rotatably connected to the inner wall of the box 1 through bearings.

[0036] like Figure 7 As shown, the movable plate 3 and the movable frame 5 are slidably connected by a guide rail slider pair.

[0037] During tool change: At this time, there is no tool on the machine tool spindle. The cylinder piston rod extends and lifts the cover plate 2, at which point the angle between the cover plate 2 and the horizontal plane is obtuse. Simultaneously, the drive rod 7 swings downwards, and under the action of the connecting rod 9, the rotating rod 8 rotates counterclockwise. Under the action of the first guide rod 12 and the first guide hole 11, the moving frame 5 moves forward. Under the control of the machine tool system, the machine tool spindle blows air to release the tool, the nozzle blows air to clean the tool's tapered surface, the spindle mates with the tool, the spindle clamps the tool and rises. The cylinder piston rod retracts to cover the housing with the cover plate 2, and the moving plate 3 and moving frame 5 reset. During tool return, the same actions are performed to return the tool to the tool magazine.
