Description

Technical Field

[0001] This utility model relates to the field of machine tool magazine technology, specifically to an automatic tool changer and push mechanism for machining centers. Background Technology

[0002] Automatic tool changer drive and push mechanism, also known as automatic tool changer system of machine tool, is usually divided into three types: hat type, disc type and chain type. In practical applications, hat type and disc type tool magazines are more common, while chain type tool magazines are used less often due to their higher cost.

[0003] The disc-type tool magazine mainly relies on its own rotating arm to complete the tool changing action. The disc-type tool magazine uses the rotating arm to quickly change tools, but the structure is relatively complex. Specifically, the rotating arm will take the tool out of the tool magazine, rotate it 180°, and then rotate the tool into the spindle, thereby completing the tool changing.

[0004] However, although existing disc-type tool magazines can achieve rapid tool changes, they still have some drawbacks:

[0005] In existing technologies, disc-type tool magazines are usually mounted on machine tools via a base. Once assembled, the disc-type tool magazine can only operate at the assembly point. Therefore, the operating range of the disc-type tool magazine is limited. If the size and specifications of the machine tool change, the assembly point of the disc-type tool magazine needs to be adjusted, resulting in poor flexibility of the disc-type tool magazine.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example: Figure 1-4As shown, this utility model provides an automatic tool changer drive and push mechanism for a machining center, including a tool changer mechanism 1. The tool changer mechanism 1 includes a tool disk 11, a rotary seat 12, a tool tilting assembly 13, a rotation control assembly 14, and a tool changer drive assembly 15. The rotary seat 12 is rotatably disposed inside the tool disk 11. The tool tilting assembly 13 is hinged to the outside of the rotary seat 12. The rotation control assembly 14 is mounted on one side of the tool disk 11, and the tool changer drive assembly 15 is mounted on one side of the rotation control assembly 14. During the tool change process, the rotation control assembly 14 can drive the rotary seat 12 to rotate inside the tool disk 11 through a motor and gear set. The tool tilting assembly 13 on the rotary seat 12 follows the revolution. When a specific tool tilting assembly 13 is rotated... When the tool disc 11 is rotated to the notch at the bottom, the cylinder in the tool tilting assembly 13 can drive the tool in the tool tilting assembly 13 to tilt, and the tool tilts from a horizontal state to a vertical state. The tool changing drive assembly 15 can clamp the tilted downward tool under the action of the motor and the cylinder, and disengage the tool from the tool tilting assembly 13. At the same time, it drives the clamped tool to rotate to the bottom of the spindle of the machine tool machining center to realize automatic tool changing. This is the disc-type tool system in the prior art, which will not be described in detail here. The rotation control assembly 14 is provided with a stroke adjustment mechanism 2. By setting the stroke adjustment mechanism 2, the working stroke of the automatic tool changing drive pushing mechanism can be expanded so as to be applicable to machine tools of different sizes and specifications.

[0025] The stroke adjustment mechanism 2 includes a frame plate 21. Several lugs 22 are fixedly mounted at both ends of the frame plate 21. Several mounting holes 23 are provided on the lugs 22. By using the lugs 22 and mounting holes 23, the frame plate 21 can be mounted on the top of the machine tool machining chamber. A movable seat 24 is slidably mounted on the lower surface of the frame plate 21. An equipment box 25 is fixedly mounted on the lower surface of the movable seat 24. A fixed plate 26 is fixedly mounted on the lower surface of the equipment box 25. A connecting rod 27 is provided on the lower surface of the fixed plate 26. A mounting plate 28 is fixedly mounted at one end of the connecting rod 27. The mounting plate 28 can be detachably mounted on the rotating... On the housing of the control component 14, the automatic tool changer push mechanism can be moved horizontally by driving the moving base 24 to move horizontally below the frame plate 21. This is achieved through the equipment box 25, the fixed plate 26, the connecting rod 27, and the mounting plate 28. Several mounting bolts 29 are threadedly mounted on the mounting plate 28. These mounting bolts 29 are threaded onto the housing of the rotary control component 14. By setting the mounting bolts 29, the mounting plate 28 can be fixed above the housing of the rotary control component 14. It can also be disassembled to separate the automatic tool changer push mechanism from the stroke adjustment mechanism 2.

[0026] A No. 1 motor 241 is fixedly installed at one end of the frame plate 21. A lead screw 242 is fixedly installed at the drive output end of the No. 1 motor 241. The lead screw 242 passes through the movable seat 24 and is threadedly connected to the movable seat 24. By starting the No. 1 motor 241, the drive shaft of the No. 1 motor 241 can make the lead screw 242 rotate. The lead screw 242 can drive the movable seat 24 to move horizontally. A slide rail 243 is fixedly installed on the lower surface of the frame plate 21. A slider 244 is slidably installed in the middle of the slide rail 243. The lower surface of the slider 244 is fixedly connected to the upper surface of the movable seat 24. By setting the slide rail 243 and the slider 244, the slider 244 can slide horizontally on the slide rail 243, thereby guiding the movable seat 24 in the horizontal direction and keeping the movable seat 24 moving horizontally.

[0027] The stroke adjustment mechanism 2 is equipped with an orientation adjustment mechanism 3. By setting the orientation adjustment mechanism 3, the orientation of the automatic tool changer drive push mechanism can be adjusted, further expanding the working range of the automatic tool changer drive push mechanism. The orientation adjustment mechanism 3 includes a rotating shaft 31, which is rotatably installed in the equipment box 25. The rotating shaft 31 is rotatably connected to the fixed plate 26. A connecting frame 32 is fixedly installed at one end of the rotating shaft 31. One end of the connecting frame 32 is fixedly connected to the other end of the connecting rod 27. By driving the rotating shaft 31 to rotate, the rotating shaft 31 can cause the connecting rod 27 to revolve in a circle through the connecting frame 32. The connecting rod 27 can cause the automatic tool changer drive push mechanism to revolve in a circle synchronously through the mounting plate 28.

[0028] A second motor 33 is fixedly installed on one side of the equipment box 25. A rotating rod 34 is fixedly installed at the drive output end of the second motor 33. A bevel gear 35 is fixedly installed at one end of the rotating rod 34 and the other end of the rotating shaft 31. The two bevel gears 35 are meshed and connected. By starting the second motor 33, the drive shaft of the second motor 33 can make the rotating rod 34 rotate. The rotating rod 34 can make the rotating shaft 31 rotate through the two bevel gears 35.

[0029] Working principle: When the automatic tool changer push mechanism is in use, the operator first assembles the frame plate 21 into the machine tool processing chamber through the lug 22, the assembly hole 23 and the bolts, and then fixes the mounting plate 28 to the housing of the rotary control component 14 through the mounting bolts 29.

[0030] During use, the No. 1 motor 241 is started. The drive shaft of the No. 1 motor 241 causes the lead screw 242 to rotate. The lead screw 242 drives the moving seat 24 to move horizontally. The moving seat 24 causes the automatic tool changer drive push mechanism to move horizontally synchronously through the equipment box 25, the fixed plate 26, the connecting rod 27 and the mounting plate 28, thereby expanding the working stroke of the automatic tool changer drive push mechanism.

[0031] Simultaneously, the second motor 33 is started, and the drive shaft of the second motor 33 causes the rotating rod 34 to rotate. The rotating rod 34 causes the rotating shaft 31 to rotate through two bevel gears 35. The rotating shaft 31 causes the connecting rod 27 to revolve in a circle through the connecting frame 32. The connecting rod 27 causes the automatic tool changer drive and push mechanism to revolve in a circle synchronously through the mounting plate 28, thereby adjusting the position of the automatic tool changer drive and push mechanism and further expanding the working range of the automatic tool changer drive and push mechanism.

[0032] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
