Technical Field

[0001] The invention relates to the technical field of a flat disc tool magazine, in particular to a flat disc tool magazine. Background Art

[0002] The tool magazine system is a device that provides tool storage and tool change requirements in the automated processing process. Its automatic tool change mechanism and tool magazine that can store multiple tools have changed the traditional human-oriented production method. Through the control of computer programs, it can complete various processing requirements, such as milling, drilling, boring, tapping, etc., greatly shortening the processing schedule and reducing production costs. This is the biggest feature of the tool magazine system.

[0003] In the prior art, a tool magazine system is a device that provides the tool storage and tool changing needs required in the automated processing process. The tool magazine system, and the existing tool magazine system is divided into a bamboo hat-type tool magazine, a disc-type tool magazine and a chain-type tool magazine. Among them, the disc-type tool magazine is usually used in a small vertical integrated processing machine, so it is small in size and compact in structure. The existing flat disc tool magazine has a compact structure itself, so it is inconvenient to install, and the installation process is very complicated. In addition, the existing flat disc tool magazine has a high cost, and the existing flat disc tool magazine can also improve the tool changing speed. Therefore, we propose a flat disc tool magazine. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings existing in the prior art. The tool magazine system is a device that provides the tool storage and tool changing needs required in the automated processing process. The tool magazine system, and the existing tool magazine system is divided into a bamboo hat type tool magazine, a disc type tool magazine and a chain type tool magazine. Among them, the disc type tool magazine is usually used in a small vertical integrated processing machine, so it is small in size and has a compact structure. The existing flat disc tool magazine has a compact structure itself, so it is inconvenient to install, and the installation process is very complicated. In addition, the existing flat disc tool magazine has a high cost, and the existing flat disc tool magazine can also be improved in tool changing speed.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A flat disc tool magazine, comprising a flat disc tool magazine as a whole, a disc tool magazine is installed on the left side of the flat disc tool magazine as a whole, a tool pushing mechanism is installed on the top of the disc tool magazine extending to the right side, and a tool changing rotating mechanism is installed at the bottom of the right side of the tool pushing mechanism;

[0007] The disc knife magazine includes a flat knife disc, the periphery of the flat knife disc is circular and fixedly connected to a knife claw seat assembly, the central part of the flat knife disc is fixedly connected to an adapter disc, a deep groove ball bearing is installed at the bottom of the adapter disc and located on the inner side of the flat knife disc, an intermediate shaft is installed on the inner side of the deep groove ball bearing extending to the bottom, a connecting plate is installed at the periphery of the intermediate shaft and located at the bottom of the flat knife disc, and the connecting plate is fixedly connected to the bottom of the flat knife disc, a hollow rotating platform is installed at the periphery of the intermediate shaft and located at the bottom of the connecting plate, and a knife magazine mounting seat is fixedly connected to the bottom of the hollow rotating platform;

[0008] The knife-pushing mechanism comprises a cylinder fixing seat, a hydraulic buffer is symmetrically fixedly connected to the top of the left side of the cylinder fixing seat, a cylinder is fixedly connected to the center of the cylinder fixing seat, a knife-pushing block is installed on the top of the cylinder and inside the cylinder fixing seat, and a limiting block is fixedly connected to the top and on the right side of the cylinder fixing seat;

[0009] The tool-changing rotating mechanism comprises a cam ATC, a rotor is mounted on the top of the cam ATC, and a tool arm motor is mounted on the left side of the cam ATC.

[0010] As a preferred solution of the present invention, a reducer is installed on the left side of the hollow rotating platform, and a servo motor is installed on the front side of the reducer.

[0011] As a preferred solution of the present invention, the flat cutter disc integrates an upper disc, a cylinder, a rib plate and a lower disc into one body, and the central upper half of the flat cutter disc is beveled at a large angle.

[0012] The technical effect of adopting the above-mentioned further scheme is: the flat cutter disc integrates the upper disc, cylinder, rib plate and lower disc into one body, and the design of the large bevel angle of the center upper half of the flat cutter disc can remove unnecessary materials while ensuring the strength of the cutter disc. This not only greatly reduces the weight of the cutter disc, but also frees up more installation space for the knife pushing mechanism, another component of the tool magazine, and lightweight holes are provided in various places of the flat cutter disc, which reduces the weight while meeting the requirements of efficiency and strength, simplifies the installation process and reduces costs.

[0013] As a preferred solution of the present invention, the knife claw seat assembly includes a knife claw seat, and the periphery of the knife claw seat is fixedly connected with a plastic knife sheath group, and the plastic knife sheath group vertically clamps the knife.

[0014] The technical effect of adopting the above-mentioned further scheme is: through the arrangement of the knife claw seat and the plastic knife sheath assembly, since the original knife claw assembly directly clamps the tool through the knife claw, the tool can only be taken out horizontally along the direction of the knife claw and cannot be directly placed into the spindle in the vertical direction through the tool changing mechanism, so the present device changes the knife claw seat structure, adds a plastic knife sheath assembly to vertically clamp the tool, and converts the horizontal pushing action of the tool to the plastic knife sheath assembly. Moreover, since the horizontal pushing action occurs on the plastic knife sheath assembly and does not directly contact the tool, the contact area, width and height of the guide rod are increased, the rigidity of the knife claw seat is greatly improved, and the mechanical action can be executed faster.

[0015] As a preferred solution of the present invention, a worm gear structure is used inside the hollow rotating platform to change the direction and position of the servo motor.

[0016] As a preferred solution of the present invention, a positioning pin hole and a limiting hole are provided at the bottom of the intermediate shaft and at the top of the tool magazine mounting seat to ensure that the intermediate shaft does not rotate or move axially.

[0017] As a preferred solution of the present invention, the cylinder is of an air-cushioned type, and the air-cushioned cylinder can reduce impact and alleviate noise.

[0018] As a preferred solution of the present invention, the rotor is modified from the original disc shape to a square shape without affecting the operation.

[0019] The technical effect of adopting the above further scheme is: by modifying the original disc shape of the rotor into a square material, it can effectively meet the requirement of leaving a certain distance on the front side of the rotor when the rotor parts stop working, while reducing its weight and reducing costs.

[0020] As a preferred solution of the present invention, the ATC shaft of the cam ATC is raised by 60 mm to accommodate tools with a tool length of 350 mm, and the transition angle of the internal cam is modified so that the tool arm connected thereto can be parked horizontally.

[0021] As a preferred solution of the present invention, one end of the oil pressure buffer penetrates into the interior of the cylinder fixing seat and is clamped with the cylinder.

[0022] The technical effect of adopting the above further solution is: through the setting of the oil pressure buffer and the cylinder clamping connection, the stability and bass requirements of the cylinder's execution action can be effectively ensured.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. In the present invention, through the arrangement of the disc tool magazine, the flat tool disc is improved from the original split design to an integrated upper disc, cylinder, rib plate and lower disc, and a large bevel is added to the upper half of the center of the tool disc, thereby removing unnecessary materials while ensuring the strength of the tool disc. This not only greatly reduces the weight of the tool disc, but also frees up more installation space for the tool pushing mechanism of another component of the tool magazine. In addition, the tool claw seat assembly is improved from the original direct clamping of the tool by the tool claw, and the tool can only be taken out horizontally along the direction of the tool claw and cannot be directly placed into the spindle in the vertical direction through the tool changing mechanism, to adding a plastic tool sleeve assembly to clamp the tool vertically, so that the horizontal pushing action of the tool can be directly converted to the plastic tool sleeve assembly, and since the horizontal pushing action occurs on the plastic tool sleeve assembly and does not directly contact the tool, the contact area, width and height of the guide rod are increased, the rigidity of the tool claw seat is greatly improved, and the mechanical action can be performed faster.

[0025] 2. In the present invention, through the setting of the tool pushing mechanism and the tool changing rotating mechanism, the cylinder is improved from the original ordinary cylinder to the air buffer type cylinder, which can effectively make the cylinder itself have the function of reducing impact and reducing noise, and the oil pressure buffer can further enhance the stability and bass requirements of the cylinder when performing the action, and the rotor is modified from the original disc type to a square material, which can not only meet the requirement of leaving a part of the distance on the front side of the rotor when the rotor parts stop working, but also effectively reduce the weight of the rotor and reduce the cost. The ATC shaft is raised by 60mm to accommodate the tool with a tool length of 350mm, and by modifying the transition angle of the internal cam, the tool arm connected to it can be parked horizontally, so that compared with the previous ATC with a 15° offset, more space can be left on the front side of the cam.

The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0037] Example 1

[0038] like Figure 1-6As shown, the present invention provides a technical solution: a flat disc tool magazine, comprising a flat disc tool magazine as a whole 1, a disc tool magazine 2 is installed on the left side of the flat disc tool magazine as a whole 1, a knife pushing mechanism 3 is installed on the top of the disc tool magazine 2 to the right side, a tool changing rotating mechanism 4 is installed at the bottom of the right side of the knife pushing mechanism 3, the disc tool magazine 2 comprises a flat cutter disc 21, the periphery of the flat cutter disc 21 is circular and fixedly connected with a knife claw seat assembly 22, a central part of the flat cutter disc 21 is fixedly connected with an adapter disc 23, a deep groove ball bearing 24 is installed at the bottom of the adapter disc 23 and located on the inner side of the flat cutter disc 21, the deep groove ball bearing 24 not only transfers the overturning moment of the intermediate shaft 25 to the entire flat cutter disc 21, but also fixes one end of the intermediate shaft 25, and changes the cantilever beam into a simply supported beam, the inner side of the deep groove ball bearing 24 extends to the bottom and the intermediate shaft 25 is installed, A connecting plate 26 is installed on the periphery of the intermediate shaft 25 and at the bottom of the horizontal cutter disc 21, and the connecting plate 26 is fixedly connected to the bottom of the horizontal cutter disc 21. A hollow rotating platform 27 is installed on the periphery of the intermediate shaft 25 and at the bottom of the connecting plate 26. A tool magazine mounting seat 28 is fixedly connected to the bottom of the hollow rotating platform 27. The knife pushing mechanism 3 includes a cylinder fixing seat 31, and an oil pressure buffer 32 is symmetrically fixedly connected to the top of the left side of the cylinder fixing seat 31. A cylinder 33 is fixedly connected to the inner center of the cylinder fixing seat 31. A knife pushing block 34 is installed on the top of the cylinder 33 and inside the cylinder fixing seat 31. The inside of the cylinder fixing seat 31 extends to the top and is fixedly connected to a limiting block 35 on the right side. The tool changing rotating mechanism 4 includes a cam ATC41, a rotor 42 is installed on the top of the cam ATC41, and a knife arm motor 43 is installed on the left side of the cam ATC41.

[0039] Example 2

[0040] like Figure 1-6 As shown, a reducer 271 is installed on the left side of the hollow rotating platform 27, and a servo motor 272 is installed on the front side of the reducer 271. The servo motor 272 and the reducer 271 can effectively drive the entire disc knife magazine 2 to rotate.

[0041] The flat cutter disc 21 integrates an upper disc, a cylinder, a rib plate and a lower disc into one body. The upper center part of the flat cutter disc 21 is beveled at a large angle, which removes unnecessary materials while ensuring the strength of the flat cutter disc 21. While reducing the weight of the flat cutter disc 21, it also provides more installation space for the blade pushing mechanism 3. Lightweight holes are provided in various places of the cutter disc, which reduces the weight while meeting the requirements of efficacy and strength, simplifies the installation process and reduces costs.

[0042] The knife claw seat assembly 22 includes a knife claw seat 221, and the periphery of the knife claw seat 221 is fixedly connected with a plastic knife sheath group 222. The plastic knife sheath group 222 vertically clamps the tool. By adding the plastic knife sheath group 222 to the knife claw seat 221, the horizontal pushing action of the tool can be converted to the plastic knife sheath group 222. The horizontal pushing action occurs on the plastic knife sheath group 222 and does not directly contact the tool, thereby increasing the contact area, width and height of the guide rod, greatly improving the rigidity of the knife claw seat 221, and can execute mechanical actions faster.

[0043] The interior of the hollow rotating platform 27 adopts a turbine worm structure to change the direction and position of the servo motor 272. The hollow rotating platform 27 serves as the driving part of the disc knife magazine 2. The interior of the hollow rotating platform 27 adopts a turbine worm structure to change the position and direction of the servo motor 272, leaving a support position for the knife pushing mechanism 3, thereby facilitating the installation of the knife pushing mechanism 3.

[0044] The bottom of the intermediate shaft 25 and the top of the knife magazine mounting seat 28 are provided with a positioning pin hole and a limit hole to ensure that the intermediate shaft 25 does not rotate and axially move. The intermediate shaft 25 is designed to support the knife pushing mechanism 3. Since the use environment and space of the tool magazine are very small and cramped, the knife pushing mechanism 3 can only be installed together with the disc knife magazine 2. The knife magazine is a rotating body. If the knife pushing mechanism 3 is directly placed on the flat knife disc 21, it will rotate with the flat knife disc 21, which cannot meet the use requirements of pushing and pulling knives. Therefore, the center of the flat knife disc 21 is hollowed out, and the intermediate shaft 25 is set separately to support the knife pushing mechanism 3. However, the knife pushing mechanism 3 has a long arm and its center of gravity is biased outward, which will form an overturning moment on the intermediate shaft 25, thereby causing the intermediate shaft 25 to The tilt of the shaft 25 will inevitably cause the intermediate shaft 25 to bend and collide with other mechanisms and collapse due to long-term use. At the bottom of the tool magazine, that is, the tool magazine mounting seat 28, positioning pin holes and limit holes are provided to ensure that the intermediate shaft 25 does not rotate or move axially, and at the top of the tool magazine, that is, the flat tool disc 21 and the top of the intermediate shaft 25 are connected with a deep groove ball bearing 24. Through the deep groove ball bearing 24, not only the overturning moment of the intermediate shaft 25 is transferred to the entire flat tool disc 21, but also the other end of the intermediate shaft 25 is fixed, and the cantilever beam is changed into a simply supported beam, thereby ensuring the rotation of the flat tool disc 21 and the fixed position of the intermediate shaft 25, and improving the rigidity and stability of the intermediate shaft 25, thereby increasing the performance and service life of the entire tool magazine.

[0045] The air cylinder 33 is of an air-cushioned type, and the air-cushioned air cylinder 33 can reduce impact and reduce noise.

[0046] The rotor 42 is modified from the original disc shape to a square material without affecting the work. The square material rotor 42 can effectively reduce weight and reduce costs.

[0047] The ATC shaft of the cam ATC41 has been raised by 60mm to accommodate tools with a tool length of 350mm, and the transition angle of the internal cam has been modified so that the tool arm connected to it can be parked horizontally. Compared with the previous ATC with a 15° offset, the front side of this cam ATC41 can leave more space.

[0048] One end of the oil pressure buffer 32 penetrates into the interior of the cylinder fixing seat 31 and is engaged with the cylinder 33 , so as to effectively buffer the cylinder 33 .

[0049] The working process of the present invention is as follows: when a flat disc tool magazine is used for tool change, first, the servo motor 272 and the reducer 271 drive the hollow rotating platform 27 to rotate, and the rotation of the hollow rotating platform 27 drives the connecting plate 26 and the flat tool disc 21 to rotate, thereby driving the disc tool magazine 2 to rotate, and the selected tool is rotated to the bottom of the tool pushing mechanism 3 through the rotation of the disc tool magazine 2, and when the tool reaches the bottom of the tool pushing mechanism 3, the cylinder 33 pushes out the piston, and the tool is sent to the tool changing position through the tool pushing block 34 connected to the piston, and when the cylinder 33 is pushing, the oil pressure buffer 32 is performing a buffering effect to reduce the piston 33 The movement speed is reduced, thereby reducing the impact sound of the cylinder, and the limit block 35 is also limiting the push-out position of the cylinder 33. When the tool moves to the tool changing position, the knife arm motor 43 starts to operate, and the cam ATC41 of the tool changing rotation mechanism 4 drives the rotor 42 to rotate under the drive of the knife arm motor 43. Through the rotation of the rotor 42, five actions of rotating to lock the knife, pulling down to draw the knife, rotating to change position, pushing up to return the knife, and returning to the position are completed. At this point, the tool change of the horizontal disc tool magazine as a whole 1 is completed. The present invention can reduce the cost of the disc tool magazine and increase the tool changing speed of the disc tool magazine through design. At the same time, it can simplify the installation process of the disc tool magazine and improve the convenience of installation work.

[0050] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
