Description

Technical Field

[0001] The invention belongs to the technical field of chain tool magazines, and in particular relates to a horizontal chain tool magazine device for production and processing of large-scale numerical control machine tools. Background Art

[0002] The tool magazine mainly provides a tool storage location, and can correctly select and position the tool according to the program control for tool exchange. The tool changing mechanism executes the tool exchange action. The tool magazine must exist at the same time as the tool changing mechanism. If there is no tool magazine, the tools required for processing cannot be reserved in advance. The characteristic of the chain-type tool magazine is that it can store a larger number of tools. It uses a chain to transfer the tool to be replaced to the specified position, and the robot installs the tool on the spindle.

[0003] Compared with the disc guide rail, the chain tool magazine has the advantage of large tool capacity, but the tools of the traditional chain tool magazine are usually placed on the chain, and the chain moves back and forth. There is no way to achieve rigid support for the entire chain. Therefore, the chain is both a load-bearing system and a transmission system, which makes the chain tool magazine have the defects of poor mechanical rigidity and large transmission gap, resulting in poor positioning accuracy of the tool magazine. In order to improve the positioning accuracy, complex detection and control circuits are required to achieve fast and accurate positioning. The equipment investment cost is high and the practical value is low.

[0004] When a general chain tool magazine is performing a tool changing operation, it usually drives the motor through a set program to rotate and transport the required blade. However, in order to achieve precise positioning, the general motor usually rotates one circle corresponding to the position change of one blade. When the motor needs to transport a blade that is far away, it will take a long time to transport the blade, thereby reducing the work efficiency of the staff and making it inconvenient for the staff to use.

[0005] A general chain tool magazine itself has a clamping device for the blade. However, in order to facilitate the operation of taking and placing the knife, the clamping device of the general chain tool magazine usually directly buckles and installs the tool. When the motor drives the blade to move quickly, the buckle is unstable when the blade is placed during the movement, which can easily cause the blade to separate from the holding device, causing the blade to fall and damage the tool magazine. Therefore, it needs to be improved and optimized. Summary of the invention

[0006] 1. Technical issues to be solved

[0007] The present invention is aimed at the above-mentioned defects existing in the prior art, and specifically proposes a horizontal chain tool magazine device for large-scale CNC machine tool production and processing, which solves the problem in the prior device that when the motor drives the blade to move rapidly, the blade is easily detached from the holding device during the movement due to the unstable buckle when placed.

[0008] 2. Technical Solution

[0009] In order to solve the above technical problems, the present invention provides a horizontal chain tool magazine device for large-scale CNC machine tool production and processing, including a driving wheel, a driven wheel is arranged on the left side of the driving wheel, the driving wheel and the driven wheel are connected through a chain block transmission, a box is fixedly installed below the driving wheel, a vertical rod located inside the box is fixedly installed at the bottom end of the driving wheel, a first turntable and a second turntable are fixedly sleeved on the outer surface of the vertical rod, a driving motor is fixedly installed at the bottom of the box inner cavity, a vertical shaft is fixedly sleeved on the other end of the output shaft of the driving motor, a second gear and a first gear are movably sleeved on the outer surface of the vertical shaft, the outer surface of the first gear is meshed with the outer surface of the first turntable, and the driving motor is fixedly installed at the bottom of the box inner cavity, The operation of the pneumatic cylinder will cause the vertical shaft to rotate, thereby driving the first gear to rotate, and the first turntable is driven to rotate by the first gear. A supporting shell is fixedly connected between the second gear and the first gear, and the inner surface of the supporting shell is movably connected to the outer surface of the vertical shaft. Due to the operation of the pneumatic cylinder, an upward force will be applied to the second gear, and the first gear will be pushed upward through the action of the supporting shell, so that the first gear is disengaged from the first turntable. At this time, the outer surface of the second gear will mesh with the outer surface of the second turntable, thereby driving the driving wheel to rotate. A pneumatic cylinder located on the left side of the driving motor is fixedly installed at the bottom end of the inner cavity of the box, and the other end of the pneumatic cylinder is movably connected to the bottom end of the second gear.

[0010] Preferably, a cross block is fixedly installed at the bottom of the left end of the chain block, a clamping block is fixedly installed on the top of the cross block, a fixed block is fixedly installed inside the cross block and the clamping block, and a vertical plate is hinged inside the fixed block. Due to the design of the vertical plate, when the bottom end of the vertical plate moves to the right, the top of the vertical plate will move to the left, thereby driving the moving block to move through the connecting rod, causing the arc block to move, which is convenient for clamping and fixing the blade.

[0011] Preferably, a movement rod is hinged at the bottom end of the vertical plate, and a rigid spring is fixedly connected to the right end of the movement rod, and the other end of the rigid spring is fixedly connected to the right end of the inner cavity of the horizontal block. Due to the design of the rigid spring, when the movement rod is squeezed and moves to the right, the rigid spring will be squeezed and put into a state of elastic compression, thereby releasing the squeezing of the movement rod. At this time, due to the elastic recovery effect of the rigid spring, a leftward force will be applied to the movement rod, causing the movement rod to reset.

[0012] Preferably, a moving block is movably installed inside the clamping block, and there are two moving blocks. A connecting rod is hinged inside each of the two moving blocks, and the other end of the connecting rod is hinged to the top of the vertical plate. A groove is provided inside the clamping block at the bottom end of the moving block. Due to the design of the connecting rod, when the blade is taken, the moving rod will be pushed inward, and the top of the vertical plate will move outward through the action of the vertical plate, thereby driving the connecting rod to apply a force to the moving block, causing the moving block to move.

[0013] Preferably, a movable block located inside the groove is fixedly installed at the bottom end of the moving block, and the outer surface of the movable block is movably connected to the groove. Due to the design of the movable block, a good limiting effect can be played on the movement of the moving block, making the movement of the moving block more stable, thereby facilitating the staff to pick up and place the blade.

[0014] Preferably, a flexible spring is fixedly connected to the side of the moving block, and the other end of the flexible spring is fixedly connected to the left wall of the inner cavity of the clamping block. There are two flexible springs, and the two flexible springs are symmetrical about the longitudinal center axis of the clamping block. Due to the design of the flexible spring, when the connecting rod pushes the moving block to the left, the flexible spring will be in a state of elastic compression. Due to the elastic recovery effect of the flexible spring, the moving block will be pushed in the opposite direction, so that the moving block is reset, and then the arc block is driven to limit the blade.

[0015] Preferably, a rectangular block is fixedly installed on the other side of the moving block, and an arc block is fixedly installed on the other end of the rectangular block. The left end of the arc block passes through the clamping block and extends to the left side of the clamping block. Due to the design of the arc block, the blade can be well fixed to prevent the blade from falling during rapid movement due to unstable installation.

[0016] Preferably, vertical plates are fixedly installed on both sides of the bottom end of the chain block, and a bottom plate is fixedly installed on the bottom end of the vertical plate. Due to the design of the bottom plate, it can provide good support for the driving wheel, the driven wheel and the chain block as a whole, making the operation of the device smoother and easier for staff to use.

[0017] Preferably, the second turntable is located below the first turntable, and a gap is left between the first turntable and the second turntable. The number and size of the grooves on the outer surfaces of the first turntable and the second turntable are different. Due to the design of the first turntable and the second turntable, the transmission wheel can be replaced according to the distance between the blades, thereby increasing the transmission speed of the blades and improving the working efficiency of the staff.

[0018] Preferably, the second gear is located below the first gear, and the second gear and the first gear are different in size. At this time, the outer surface of the first gear is meshed with the outer surface of the first turntable. When the staff needs to speed up the transmission speed of the blade, the second gear will move upward and mesh with the outer surface of the second turntable. At this time, the first gear will move upward and disengage from the outer surface of the first turntable, thereby speeding up the delivery speed of the blade.

[0019] 3. Beneficial Effects

[0020] Compared with the prior art, the present invention sets a first turntable, a driving motor, a vertical shaft and a first gear. Due to the operation of the driving motor, the vertical shaft will rotate, thereby driving the second gear and the first gear to rotate together. At this time, the outer surface of the first turntable and the outer surface of the first gear are in a state of mutual meshing. When the outer surface of the first gear and the outer surface of the first turntable are meshed with each other once, the blade position on the chain block will be driven by one knife position. Due to the rotation of the first gear, the first turntable will be driven to rotate, and then the driving wheel will be rotated through the vertical rod, so that fast and precise positioning can be achieved without assembling complex detection and control circuits, thereby reducing production costs and improving the practicality of the device.

[0021] By setting a second turntable, a second gear, a pneumatic cylinder and a supporting shell, the operation of the pneumatic cylinder will apply an upward thrust to the second gear, so that the second gear drives the supporting shell to push the first gear upward. At this time, the outer surface of the first gear will be disengaged from the outer surface of the first turntable, and the outer surface of the second gear will be meshed with the outer surface of the second turntable. Due to the operation of the driving motor, the second gear will rotate, thereby driving the second turntable to rotate, and the driving wheel will rotate through the vertical rod, thereby realizing the rapid transportation of the blade, reducing the waiting time for transporting the blade when replacing the blade, and improving the work efficiency of the staff.

[0022] By setting the vertical plate, moving rod, rigid spring, moving block and arc block, when the blade is placed, the moving rod will be squeezed first to make the moving rod move to the right. At this time, the rigid spring is in a state of elastic compression. Due to the transmission action of the vertical plate, the bottom end of the vertical plate moves to the right, which will make the top of the vertical plate move to the left, thereby making the moving block move to both sides through the connecting rod. During the movement of the moving block, the arc block will be driven to move to both sides through the rectangular block. When the blade is placed on the clamping block, the squeezing force on the moving rod disappears. At this time, due to the elastic recovery effect of the rigid spring, the moving rod will be reset, and the top of the vertical plate will move to the right, thereby driving the moving block to move to the right. At this time, the arc block will move together with the moving block and make the right end of the arc block enter the interior of the blade, thereby achieving a good fixing effect on the blade, avoiding falling off due to unstable installation during rapid movement, causing damage to the tool magazine.

DETAILED DESCRIPTION

[0032] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0033] Embodiment 1:

[0034] like Figures 1 to 7 As shown, in the embodiment of the present invention, a horizontal chain tool magazine device for large-scale CNC machine tool production and processing includes a driving wheel 1, a driven wheel 2 is provided on the left side of the driving wheel 1, the driving wheel 1 and the driven wheel 2 are connected through a chain block 3, a box body 4 is fixedly installed below the driving wheel 1, a vertical rod 5 located inside the box body 4 is fixedly installed at the bottom end of the driving wheel 1, a first turntable 6 and a second turntable 7 are fixedly sleeved on the outer surface of the vertical rod 5, a driving motor 8 is fixedly installed at the bottom of the inner cavity of the box body 4, a vertical shaft 9 is fixedly sleeved on the other end of the output shaft of the driving motor 8, a second gear 10 and a first gear 11 are movably sleeved on the outer surface of the vertical shaft 9, the outer surface of the first gear 11 is meshed with the outer surface of the first turntable 6, and the operation of the driving motor 8 will cause the vertical shaft 9 to rotate. , thereby driving the first gear 11 to rotate, and the first turntable 6 is driven to rotate through the first gear 11. A support shell 13 is fixedly connected between the second gear 10 and the first gear 11, and the inner surface of the support shell 13 is movably connected with the outer surface of the vertical shaft 9. As the pneumatic cylinder 12 runs, an upward force will be applied to the second gear 10, and the first gear 11 will be pushed upward through the support shell 13, so that the first gear 11 is disengaged from the first turntable 6. At this time, the outer surface of the second gear 10 will mesh with the outer surface of the second turntable 7, thereby driving the driving wheel 1 to rotate. A pneumatic cylinder 12 located on the left side of the drive motor 8 is fixedly installed at the bottom end of the inner cavity of the box body 4, and the other end of the pneumatic cylinder 12 is movably connected to the bottom end of the second gear 10.

[0035] like Figure 6 As shown, a cross block 14 is fixedly installed at the bottom of the left end of the chain block 3, a clamping block 15 is fixedly installed on the top of the cross block 14, a fixed block 16 is fixedly installed inside the cross block 14 and the clamping block 15, and a vertical plate 17 is hinged inside the fixed block 16. Due to the design of the vertical plate 17, when the bottom end of the vertical plate 17 moves to the right, the top of the vertical plate 17 will move to the left, thereby driving the moving block 20 to move through the connecting rod 21, causing the arc block 26 to move, which is convenient for clamping and fixing the blade.

[0036] like Figure 4As shown, a moving rod 18 is hinged at the bottom end of the vertical plate 17, and a rigid spring 19 is fixedly connected to the right end of the moving rod 18. The other end of the rigid spring 19 is fixedly connected to the right end of the inner cavity of the cross block 14. Due to the design of the rigid spring 19, when the moving rod 18 is squeezed and moves to the right, the rigid spring 19 will be squeezed and put in a state of elastic compression, and the squeezing of the moving rod 18 will be released. At this time, due to the elastic recovery effect of the rigid spring 19, a leftward force will be applied to the moving rod 18, so that the moving rod 18 will be reset.

[0037] like Figure 6 , Figure 7 The clamping block 15 shown has a moving block 20 movably installed inside. There are two moving blocks 20. A connecting rod 21 is hinged inside each of the two moving blocks 20. The other end of the connecting rod 21 is hinged to the top of the vertical plate 17. A groove 22 is provided inside the clamping block 15 at the bottom end of the moving block 20. Due to the design of the connecting rod 21, when the blade is taken, the moving rod 18 will be pushed inward. Through the action of the vertical plate 17, the top of the vertical plate 17 will move outward, thereby driving the connecting rod 21 to apply a force to the moving block 20, causing the moving block 20 to move.

[0038] Among them, a movable block 23 located inside the groove 22 is fixedly installed at the bottom end of the moving block 20, and the outer surface of the movable block 23 is movably connected to the groove 22. Due to the design of the movable block 23, it can play a good limiting role in the movement of the moving block 20, making the movement of the moving block 20 more stable, thereby facilitating the staff to pick up and place the blade.

[0039] like Figure 7 As shown, a flexible spring 24 is fixedly connected to the side of the motion block 20, and the other end of the flexible spring 24 is fixedly connected to the left wall of the inner cavity of the clamping block 15. There are two flexible springs 24, and the two flexible springs 24 are symmetrical about the longitudinal center axis of the clamping block 15. Due to the design of the flexible spring 24, when the connecting rod 21 pushes the motion block 20 to the left, the flexible spring 24 will be in an elastic compression state. Due to the elastic recovery effect of the flexible spring 24, the motion block 20 will be pushed in the opposite direction, so that the motion block 20 is reset, and then the arc block 26 is driven to limit the blade. A rectangular block 25 is fixedly installed on the other side of the motion block 20, and an arc block 26 is fixedly installed on the other end of the rectangular block 25. The left end of the arc block 26 passes through the clamping block 15 and extends to the left side of the clamping block 15. Due to the design of the arc block 26, it can play a good fixing role on the blade, and prevent the blade from falling due to unstable installation during rapid movement.

[0040] In addition, vertical plates 27 are fixedly installed on both sides of the bottom end of the chain block 3, and a bottom plate 28 is fixedly installed on the bottom end of the vertical plate 27. Due to the design of the bottom plate 28, it can provide good support for the driving wheel 1, the driven wheel 2 and the chain block 3 as a whole, making the operation of the device smoother and easier for the staff to use.

[0041] like Figure 1 As shown, the second turntable 7 is located below the first turntable 6, and a gap is left between the first turntable 6 and the second turntable 7. The number and size of the grooves on the outer surfaces of the first turntable 6 and the second turntable 7 are different. Due to the design of the first turntable 6 and the second turntable 7, the transmission wheel can be replaced according to the distance between the blades, thereby increasing the transmission speed of the blades and improving the working efficiency of the staff.

[0042] Among them, the second gear 10 is located below the first gear 11, and the second gear 10 and the first gear 11 are of different sizes. At this time, the outer surface of the first gear 11 is meshed with the outer surface of the first turntable 6. When the staff needs to speed up the transmission speed of the blade, the second gear 10 will move upward and mesh with the outer surface of the second turntable 7. At this time, the first gear 11 will move upward and disengage from the outer surface of the first turntable 6, thereby speeding up the delivery speed of the blade.

[0043] During the specific operation, first, when the staff needs to replace the blade, the staff starts the driving motor 8. Due to the operation of the driving motor 8, the vertical shaft 9 will rotate, thereby driving the second gear 10 and the first gear 11 to rotate together. At this time, the outer surface of the first turntable 6 and the outer surface of the first gear 11 are in a state of mutual meshing. When the outer surface of the first gear 11 and the outer surface of the first turntable 6 are meshed once, the blade position on the chain block 3 will be driven by one knife position. Due to the rotation of the first gear 11, the first turntable 6 will be driven to rotate, and then the driving wheel 1 will be rotated through the vertical rod 5, so that fast and accurate positioning can be achieved without assembling a complex detection and control circuit.

[0044] When the blade to be replaced is far away, the staff starts the pneumatic cylinder 12. Due to the operation of the pneumatic cylinder 12, an upward thrust will be applied to the second gear 10, so that the second gear 10 drives the supporting shell 13 to push the first gear 11 upward. At this time, the outer surface of the first gear 11 will be disengaged from the outer surface of the first turntable 6, and the outer surface of the second gear 10 will be meshed with the outer surface of the second turntable 7. Due to the operation of the drive motor 8, the second gear 10 will rotate, thereby driving the second turntable 7 to rotate, and the driving wheel 1 will rotate through the vertical rod 5, so that the rotation speed of the driving wheel 1 is faster, so as to facilitate the rapid transportation of the farther blade;

[0045] When the driving wheel 1 rotates so that the blade reaches the corresponding replacement position, when the blade is taken, the moving rod 18 will be squeezed first, so that the moving rod 18 moves to the right. At this time, the rigid spring 19 is in a state of elastic compression. Due to the transmission effect of the vertical plate 17, the bottom end of the vertical plate 17 moves to the right, which will cause the top of the vertical plate 17 to move to the left, so that the moving block 20 moves to both sides through the connecting rod 21. During the movement of the moving block 20, the arc block 26 will move to both sides to the inside of the clamping block 15 through the rectangular block 25, thereby releasing the fixing effect on the blade.

[0046] After removing the blade, put the replaced blade into the clamping block 15, and then release the squeezing force on the moving rod 18. Since the squeezing force on the moving rod 18 disappears, the moving rod 18 will be reset due to the elastic recovery effect of the rigid spring 19, so that the top of the vertical plate 17 moves to the right, thereby driving the moving block 20 to move to the right. At this time, the arc block 26 will move together with the moving block 20 and make the right end of the arc block 26 enter the interior of the blade to fix the blade.

[0047] The above are only preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
