[0016] Compared with the prior art, the present invention provides a tool changing device with a chain tool magazine, having the following beneficial effects:

[0017] 1. For this tool changing device with a chain tool magazine, by setting an electric slide rail, a driven column, an intercepting arm, a trigger plate, a pressure sensor, and an electric push rod, during the tool taking process, the electric slide rail drives the intercepting arm to reach the path of the tool sleeve. The tool sleeve continues to move forward along the established trajectory under the drive of the tool magazine. During this process, the intercepting arm first contacts the tool sleeve, and the intercepting arm deflects under the drive of the tool sleeve. When the intercepting arm reaches its maximum deflectable angle and cannot deflect further, the tool sleeve continues to move forward and pushes the intercepting arm, the sleeve, the driven column, and the electric push rod to move synchronously along the first slide rail, enabling the electric push rod to remain stationary relative to the tool sleeve, thereby achieving the purpose of dynamic tool taking during the continuous movement of the tool sleeve. The entire process does not require shutting down the entire tool magazine device, greatly improving the tool changing efficiency and continuous operation ability of the tool magazine. At the same time, the pressure sensor is used to continuously sense the force condition of the intercepting arm, realizing precise control of the electric push rod and the tool taking process, making the tool changing operation more accurate and stable, reducing human intervention, and enhancing the automation level and intelligent degree of the entire tool magazine system.

[0018] 2. For this tool changing device with a chain tool magazine, by setting the first slide rail, the insertion rod, the push plate, and the elastic cord, when the driven column moves along the first slide rail under the drive of the tool sleeve, the upper pulley, the insertion rod, and the push plate move synchronously. During this process, the push plate and the fixed ring stretch the elastic cord. After the tool taking is completed, the intercepting arm leaves the tool sleeve under the drive of the electric slide rail, and the stretched elastic cord loses the external pulling force, driving the driven column to achieve automatic reset through the insertion rod.

[0019] 3. The tool changing device with a chain tool magazine, by setting a limiting rod, a rotating rod, a fixture and a second slide rail, when the electric push rod expands and contracts, it drives the fixture top seat to move up and down. Through the limitation of the outside of the fixture by the rotating rod, the opening and closing angle of the fixture can be changed, so as to realize the clamping and releasing of the tool. Through the cooperation of the electric push rod and the rotating rod, when the fixture approaches the tool, it can quickly and accurately grab and release the tool by using a simple transmission structure. The rotating design of the rotating rod is beneficial to reducing the wear on the fixture. The second slide rail at the top of the fixture provides guiding and limiting functions for both ends of the rotating rod, enabling the rotating rod to slide smoothly on the fixture, improving the stability and accuracy of the movement of the rotating rod, further optimizing the working performance of the clamping mechanism, and ensuring the reliability of tool clamping.

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0030] Referring to Figure 1-8 , a tool changing device with a chain tool magazine, including a base 1, a support pillar 2 and a top plate 3. The support pillar 2 is fixedly connected to the top of the base 1, the top plate 3 is fixedly connected to the top of the support pillar 2, an electric slide rail 4 is fixedly connected to the bottom of the top plate 3, an upper slider 5 is slidably connected to the bottom of the electric slide rail 4, a first slide rail 6 is fixedly connected to the bottom of the upper slider 5, a driven column 8 is slidably connected to the bottom of the first slide rail 6, a suspension bracket 15 is fixedly connected to the top of the driven column 8, a fixing hoop 16 is fixedly connected to the end of the suspension bracket 15 away from the driven column 8, an electric push rod 17 with a telescopic end facing downwards is fixedly connected to the inside of the fixing hoop 16, a clamping mechanism is arranged at the bottom of the electric push rod 17, a sleeve 10 is fixedly connected to the middle of the driven column 8, an intercepting arm 11 is rotatably connected to the outer wall of the sleeve 10, the same second spring 37 is fixedly connected between the intercepting arm 11 and the sleeve 10, a trigger plate 42 is fixedly connected to the end of the intercepting arm 11 close to the sleeve 10, and a pressure sensor 43 adapted to the trigger plate 42 is fixedly connected to the outer wall of the sleeve 10.

[0031] In the present invention, a connecting frame 14 is fixedly connected to the middle position of the bottom of the first slide rail 6, the bottom of the connecting frame 14 is fixedly connected to another first slide rail 6, pulleys 7 are rotatably connected to both ends of the driven column 8, the two pulleys 7 are respectively slidably connected to the inside of the two first slide rails 6, and the pulleys 7 at both ends of the driven column 8 slide in the two first slide rails 6 respectively, so that the driven column 8 can move more smoothly. The connecting frame 14 connects the two first slide rails 6, enhancing the structural stability.

[0032] In the present invention, a plug rod 23 is fixedly connected to one side of the pulley 7 located above. A fixing ring 22 is sleeved on the middle part of the plug rod 23. The fixing ring 22 is fixedly connected to one side of the adjacent first slide rail 6. One end of the plug rod 23 away from the pulley 7 is fixedly connected to a push plate 24. An elastic cord 25 is fixedly connected between the push plate 24 and the fixing ring 22. When the driven column 8 moves along the first slide rail 6 driven by the knife sheath, the upper pulley 7, the plug rod 23 and the push plate 24 move synchronously. During this process, the push plate 24 and the fixing ring 22 stretch the elastic cord 25. After the knife-taking is completed, the intercepting arm 11 leaves the knife sheath driven by the electric slide rail 4. The stretched elastic cord 25 loses the external pulling force, and the driven column 8 is driven by the plug rod 23 to achieve automatic reset.

[0033] In the present invention, the clamping mechanism includes a clamp 18, a limiting rod 21, a clamp top seat 38 and a rotating rod 46. The clamp top seat 38 is fixedly connected to the bottom of the electric push rod 17. Two clamps 18 are symmetrically hinged to both sides of the bottom of the clamp top seat 38. Two limiting rods 21 are symmetrically fixed below the fixing hoop 16. Two rotating rods 46 are respectively rotatably connected to the bottoms of the two limiting rods 21. The two rotating rods 46 respectively press on the tops of the two clamps 18. Anti-slip grooves 45 are respectively formed at the bottoms of the sides where the two clamps 18 are close to each other. The anti-slip grooves 45 can increase the friction between the clamp 18 and the tool, preventing the tool from slipping. The rotating design of the rotating rod 46 is beneficial to reducing the wear caused to the clamp 18. The telescopic movement of the electric push rod 17 can drive the clamp top seat 38 to move up and down. By limiting the outside of the clamp 18 through the limiting rod 21 and the rotating rod 46, the opening and closing angle of the clamp 18 can be changed, so as to realize the clamping and release of the tool. Controlling the electric push rod 17 to contract upward, through the cooperation of the electric push rod 17 and the rotating rod 46, the tool can be pulled up from the knife sheath while clamping the tool.

[0034] In the present invention, a downward-probing bracket 19 is fixedly connected to the bottom of the fixing hoop 16. The bottom of the downward-probing bracket 19 is fixedly connected to a C-shaped member 20. The two ends of the C-shaped member 20 are respectively located on both sides of the electric push rod 17. Two limiting rods 21 are respectively fixedly connected to the bottoms of the two ends of the C-shaped member 20. The downward-probing bracket 19 and the C-shaped member 20 at the bottom of the fixing hoop 16 provide stable support for the limiting rod 21, enabling the limiting rod 21 to move synchronously with the electric push rod 17, accurately positioning and fixing the rotating rod 46, and ensuring the stable cooperation between the rotating rod 46 and the clamp 18.

[0035] In the present invention, both sides of the top of the fixture 18 are fixedly connected with second slide rails 44. The two ends of the rotating rod 46 are respectively slidably connected inside the two second slide rails 44 connected to the adjacent fixture 18. The second slide rails 44 at the top of the fixture 18 provide guiding and limiting functions for the two ends of the rotating rod 46, enabling the rotating rod 46 to slide smoothly on the fixture 18, improving the stability and accuracy of the movement of the rotating rod 46, further optimizing the working performance of the clamping mechanism, and ensuring the reliability of tool clamping.

[0036] In the present invention, the sleeve 10 is slidably connected to the column body of the driven column 8. One side of the sleeve 10 is threadedly connected with a stud 39. The end of the stud 39 located outside the sleeve 10 is fixedly connected with a knob 13. The end of the stud 39 located inside the sleeve 10 is fixedly connected with a pressing head 40. A positioning groove 9 is formed on one side of the driven column 8. The pressing head 40 is slidably connected inside the positioning groove 9. The sleeve 10 can slide up and down along the driven column 8, thereby adjusting the height of the intercepting arm 11 to adapt to different types of tool sleeves. After the height adjustment of the sleeve 10 is completed, the stud 39 is rotated by the knob 13 to press the pressing head 40 against the inner wall of the positioning groove 9, completing the positioning of the sleeve 10 and expanding the applicable range of the device.

[0037] In the present invention, two parallel shaft seats 41 are fixedly connected to the outer wall of the sleeve 10. The intercepting arm 11 is rotatably connected between the two shaft seats 41. A rubber pad 12 is embedded on one side of the intercepting arm 11 close to the second spring 37. The intercepting arm 11 is rotatably connected to the sleeve 10 through the shaft seats 41. The rubber pad 12 plays a buffering and protecting role during the process of the intercepting arm 11 intercepting the tool sleeve.

[0038] In the present invention, a socket plate 34 is fixedly connected to the top of the base 1. The support column 2 is rotatably connected to the middle position of the top of the socket plate 34. A ring of equally spaced pin holes is formed on the top of the socket plate 34. A pin bracket 32 is fixedly connected to the bottom of the support column 2. A pin 33 is inserted on one side of the pin bracket 32. The bottom end of the pin 33 is located inside one of the pin holes. By pulling out the pin 33, the angle of the tool changing device can be adjusted by rotating the support column 2. The pin 33 is reinserted into the pin bracket 32, and the bottom of the pin 33 is inserted into the corresponding pin hole, thereby fixing the adjusted angle of the support column 2, enabling the tool changing device to adapt to different working scenarios and tool changing requirements, and improving the applicability and flexibility of the device.

[0039] In the present invention, a guide rail 26 is fixedly connected to the top of the base 1. A lower slider 27 is slidably connected to the top of the guide rail 26. A material receiving box 28 is fixedly connected to the top of the lower slider 27. A baffle 29 is hinged to one side wall of the material receiving box 28. A speed bump 30 is fixedly connected to the top of the baffle 29. Pressing plates 35 are fixedly connected to the inner walls on both sides of the material receiving box 28. First springs 36 are fixedly connected between the two pressing plates 35 and the baffle 29. A pulling handle 31 is fixedly connected to one side of the lower slider 27 to control the removed tool to fall into the material receiving box 28. When the tool falls into the material receiving box 28, an impact force will be generated on the baffle 29. The pressing plate 35 and the baffle 29 are connected by the first spring 36, and the first spring 36 can play a buffering role. The speed bump 30 can slow down the speed of the tool falling into the material receiving box 28. The pulling handle 31 facilitates the user to pull the lower slider 27 to move the material receiving box 28, which is convenient for the collection and sorting of tools.

[0040] During use, the whole tool changing device with a chain tool magazine is installed at the tool changing station of the chain tool magazine. A stable support frame is constructed by the base 1, the pillar 2 and the top plate 3. The first slide rail 6 is adapted to the movement track of the tool sleeve. In the initial state, the clamping mechanism is debugged according to the movement track of the tool sleeve and the specification model of the tool sleeve to ensure that the tool sleeve passes between the two clamps 18 of the clamping mechanism during movement. Then, the electric slide rail 4 drives the upper slider 5 to move to one end close to the pillar 2 to prepare for subsequent actions. When a tool change is needed, the electric slide rail 4 drives the upper slider 5 to move in the opposite direction away from the pillar 2 until the intercepting arm 11 reaches the path of the tool sleeve. The tool sleeve continues to move forward along the established track driven by the tool magazine. During this process, the intercepting arm 11 first contacts the tool sleeve, and the intercepting arm 11 deflects under the drive of the tool sleeve. The second spring 37 buffers the force on the intercepting arm 11. When the intercepting arm 11 reaches its maximum deflectable angle and cannot deflect further, the tool sleeve continues to move forward and pushes the intercepting arm 11, the sleeve 10, the driven column 8 and the electric push rod 17 to move synchronously along the first slide rail 6, so that the electric push rod 17 can remain stationary relative to the tool sleeve. The deflection of the intercepting arm 11 drives the trigger plate 42 to press the pressure sensor 43, and the electric push rod 17 is controlled to contract upward through the generated electrical signal. The clamping mechanism moves upward together under the drive of the electric push rod 17 and clamps the tool during the upward movement, pulling the tool out of the tool sleeve. Then, the electric slide rail 4 drives the upper slider 5 to reset, thus completing the tool taking.

[0041] The above tool taking process realizes dynamic tool taking under the condition of continuous movement of the tool sleeve. The whole process does not require shutting down the tool magazine equipment, greatly improving the tool changing efficiency and continuous operation ability of the tool magazine. At the same time, the pressure sensor 43 is used to sense the force on the intercepting arm 11 in real time to realize precise control of the electric push rod 17 and the tool taking process, making the tool changing operation more accurate and stable, reducing human intervention, and improving the automation level and intelligent degree of the whole tool magazine system.

[0042] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
