Description

Technical Field

[0002] In CNC machining equipment, the live toolholder is a key component widely used in complex machining processes such as turning and milling. To improve tool change efficiency and reduce auxiliary time, existing technologies often use a rotating live toolholder. This structure involves multiple tool mounting stations mounted on a rotating toolholder body. Each station can accommodate a different type of cutter head, and the toolholder is rotated to switch between different tools for machining.

[0003] The existing tools are usually installed on the tool holder by bolts. During installation, multiple tools need to be screwed to the outer wall of the tool holder one by one by bolts. However, since each tool needs to be installed with four bolts, it takes a lot of time to install multiple tools on the tool holder one by one, and the installation efficiency is low. Moreover, when the tool rotates to process the workpiece, the drill bit on the rotating tool will contact the workpiece, so vibration will be generated during processing. Long-term vibration can easily cause the bolts to loosen, which in turn makes the drill bit on the tool easily deviate and shake during processing, causing damage to the drill bit on the tool.

This arrangement enables the threaded rods 401 on both sides to rotate synchronously.

[0042] As a further solution of the present invention, a rotating shaft 508 is movably connected to the middle of a side surface of the inner wall of the turntable 100, an outer ring gear disc 507 is fixed to the bottom surface of the rotating shaft 508, and several of the fifth gears 505 are respectively engaged with the outer ring gear disc 507.

A second linear rack 509 is fixed to one side of the side block 510, and the second linear rack 509 is engaged with the seventh gear 512.

[0043] By setting up the second hydraulic cylinder 511, the second linear rack 509, the seventh gear 512 and the outer ring gear disc 507, the second hydraulic cylinder 511 can drive the second linear rack 509 to move when it is started, thereby causing the seventh gear 512 to rotate, and finally causing the outer ring gear disc 507 to rotate, driving the several fifth gears 505 to rotate synchronously. This setting enables the several U-shaped racks 501 to achieve synchronous movement, ensuring the identity of the movement.

[0044] As a further solution of the present invention, several circularly distributed fixing frames 200 are fixed to the other side of the inner wall of the turntable 100, and two positioning columns 201 are movably connected to the top surface of the fixing frame 200.

A first T-shaped bar 204 is fixed to the bottom surface of the positioning column 201, and a fixing ring 205 is fixed between several of the first T-shaped bars 204. An inner bar 206 is fixed to the inner wall of the fixing ring 205. A first hydraulic cylinder 207 is fixed to the other side of the inner wall of the turntable 100, and the output end of the first hydraulic cylinder 207 is fixed to the bottom surface of the inner bar 206.

[0045] By setting the first hydraulic cylinder 207, the fixing ring 205 can be moved, thereby driving the synchronous movement of the first T-shaped bars 204, so that the top bars 203 can be moved synchronously; by setting the first spring 202 and the top bar 203, after the cutting tools 110 are placed in the mounting hole 113, the docking joints 112 thereon can be pushed by the top bar 203, so that the top bars 203 are in a horizontal position, which facilitates the docking of the docking joints 112 with the U-shaped head 109.

[0046] The docking head 112 is fixed to one end of the shaft of the tool 110 .

[0047] As a further solution of the present invention, a first sleeve 102 is movably connected to the middle of the other side surface of the inner wall of the turntable 100, and an outer shell 101 is fixed to the bottom of the first sleeve 102. An intermediate shell 103 is connected to the top surface of the first sleeve 102, and a second sleeve 104 is connected to the outer wall of the intermediate shell 103. A first rotating rod 105 is movably connected inside the first sleeve 102, and a first bevel gear 106 is fixed to the top surface of the first rotating rod 105. A second rotating rod 108 is movably connected inside the second sleeve 104, and a second bevel gear 107 is fixed to one end of the second rotating rod 108. The second bevel gear 107 is meshed with the first bevel gear 106, and a U-shaped head 109 is fixed to the other end of the second rotating rod 108.

[0048] By setting the first rotating rod 105, the second rotating rod 108, the first bevel gear 106, and the second bevel gear 107, when the first rotating rod 105 rotates, the second rotating rod 108 can be driven to rotate through the transmission of the first bevel gear 106 and the second bevel gear 107, thereby driving the U-shaped head 109 to rotate, so that the docking head 112 engaged with the U-shaped head 109 rotates, and then driving the tool 110 thereon to rotate.

[0049] As a further solution of the present invention, an annular groove 300 is formed on the top surface of the shell 101, a rotating tube 301 is fixed to the bottom surface of the outer wall of the turntable 100, and the bottom of the rotating tube 301 is movably connected to the annular groove 300, a geared ring 302 is fixed to the bottom of the outer wall of the rotating tube 301, a first motor 303 is fixed to one side of the top surface of the inner wall of the shell 101, a first gear 304 is fixed to the output end of the first motor 303, and the first gear 304 is engaged with the geared ring 302, a second gear 305 is fixed to the bottom of the outer wall of the first rotating rod 105, a second motor 307 is fixed to the top surface of the inner wall of the shell 101, a third gear 306 is fixed to the output end of the second motor 307, and the third gear 306 is engaged with the second gear 305, a PLC controller 308 is fixed to one side of the inner wall of the shell 101, and the first motor 303 and the second motor 307 are electrically connected to the PLC controller 308 respectively.

[0050] By means of the provided rotating tube 301 and the annular groove 300, the turntable 100 can be movably connected to the housing 101; by means of the provided toothed ring 302, the first motor 303 and the first gear 304, the rotating tube 301 can rotate, thereby driving the turntable 100 to rotate; by means of the provided second gear 305, the third gear 306 and the second motor 307, the first rotating rod 105 can rotate; by means of the provided PLC controller 308, the rotation of the first motor 303 and the second motor 307 can be controlled, thereby facilitating the switching of the tool 110 and controlling the rotation of the tool 110.

[0051] As a further solution of the present invention, two first limiting strips 404 are fixed between the two upper and lower fixed blocks 400, and limiting openings 405 are respectively opened on the opposite sides of the outer side wall of the first L-shaped strip 403, and the first limiting strips 404 are correspondingly engaged in the limiting openings 405.

[0052] By providing the first limiting strip 404 and the limiting opening 405 , the position of the first L-shaped strip 403 can be limited, thereby preventing the first L-shaped strip 403 from rotating when the threaded rod 401 rotates.

[0053] As a further solution of the present invention, the inner side walls of the second L-shaped bar 409 are respectively provided with limiting grooves 411 on the two opposite side surfaces, and the mortgage block 410 is respectively fixed with second limiting bars 414 on the two opposite side surfaces, and the second limiting bars 414 are correspondingly and movably engaged in the limiting grooves 411.

[0054] By providing the limiting groove 411 and the second limiting strip 414 , the position of the mortgage block 410 can be movably limited, thereby preventing the mortgage block 410 from moving out of the second L-shaped strip 409 and falling.

[0055] As a further solution of the present invention, a movable column 415 is fixed on the top surface of the mortgage block 410, and a plurality of openings 416 distributed in a circle and corresponding to the movable columns 415 are opened on the side of the outer wall of the turntable 100 away from the outer shell 101, and the movable columns 415 pass through the openings 416.

[0056] By setting the opening 416 , when the movable column 415 is pushed to move, the movable column 415 can move in the opening 416 without being blocked by the turntable 100 . The opening 416 is a rectangular hole.

[0057] In summary: when clamping the tool 110, first rotate the U-shaped head 109 on the tools 110 of several different drill bits so that the U-shaped head 109 is not in a vertical state and remains approximately horizontal; then the tools 110 are clamped in the mounting hole 113 one by one, and then the second hydraulic cylinder 511 is started. The second hydraulic cylinder 511 pushes the second linear rack 509 to move, thereby driving the seventh gear 512 to rotate, and the rotation of the seventh gear 512 drives the outer ring gear disk 507 to rotate, and the rotation of the outer ring gear disk 507 drives the several fifth gears 505 to rotate, and the rotation of the fifth gear 505 drives the rotation shaft 504 to rotate, and the rotation of the rotation shaft 504 drives the sixth gear 506 rotates, and the sixth gear 506 rotates to drive the first linear rack 503 to move, thereby causing the U-shaped rack 501 to move. The movement of the U-shaped rack 501 drives the two fourth gears 402 engaged with it to rotate, thereby causing the threaded rods 401 on both sides to rotate. The rotation of the threaded rod 401 drives the first L-shaped bar 403 to move upward. The upward movement of the first L-shaped bar 403 causes the trapezoidal block 406 to contact the chamfered angle position of the second L-shaped bar 409, and push the second L-shaped bar 409 to move. The movement of the second L-shaped bar 409 pushes the mortgage block 410 to move, so that the end face of the mortgage block 410 contacts the inner wall of the side opening 111, so that the tool 110 is stably pushed to achieve clamping.

[0058] During the process of inserting the tool 110 into the mounting hole 113, the chamfered corners on both sides of the tool 110 contact the inclined surface of the mortgage block 410 and push the mortgage block 410 close to the threaded rod 401. At this time, the second spring 413 is compressed. When the chamfered corners on both sides of the tool 110 pass over the mortgage block 410, the second spring 413 pushes the mortgage block 410 so that the mortgage block 410 is located in the side opening 111.

[0059] When removing the tool 110, the two movable columns 415 on the corresponding tool 110 are manually pushed to both sides so that the two movable columns 415 move away from each other. At this time, the second spring 413 is compressed, and the mortgage block 410 moves out from the side opening 111. The mortgage block 410 will not block the tool 110.

[0060] like Figure 4 As shown, at this time, the cutter 110 is engaged in the mounting hole 113 , and the mounting hole 113 and the cutter 110 are stably engaged, and the cutter 110 does not shake.

[0061] When the docking joints 112 on several tools 110 are synchronously leveled, the first hydraulic cylinder 207 is started, and the first hydraulic cylinder 207 pushes the fixed ring 205 to move. The movement of the fixed ring 205 drives the movement of several first T-bars 204. The movement of the first T-bar 204 drives the top bar 203 to move. During the movement of the top bar 203, the top bar 203 gradually contacts the docking joint 112. At this time, the inclined docking joint 112 rotates until the docking joint 112 is completely in a horizontal state. During this process, the distance moved by the output end of the first hydraulic cylinder 207 is a constant distance, that is, the distance moved by the output end of the first hydraulic cylinder 207 when the inclined state of the docking joint 112 changes to a horizontal state.

[0062] When the tool 110 is connected to the U-shaped head 109, the PLC controller 308 is operated. The PLC controller 308 controls the first motor 303 to rotate. The rotation of the first motor 303 drives the first gear 304 to rotate. The rotation of the first gear 304 drives the gear ring 302 to rotate. The rotation of the gear ring 302 drives the rotating tube 301 to rotate, thereby causing the turntable 100 to rotate. The rotation of the turntable 100 drives the plurality of tools 110 to rotate. At this time, the docking joints 112 on the plurality of tools 110 pass through the U-shaped head 109 until the docking joints 112 on the corresponding tools 110 are engaged in the U-shaped head 109. At this time, the tool 110 is docked with the U-shaped head 109. Then the output end of the first hydraulic cylinder 207 is controlled to move downward so that the fixing ring 205 moves downward. The second gear 305 is rotated to drive the second gear 305 to rotate, and the second gear 305 is rotated to drive the first rotating rod 105 to rotate. The first rotating rod 105 is rotated to drive the first bevel gear 106 to rotate. The first bevel gear 106 is rotated to drive the second bevel gear 107 to rotate. The second bevel gear 107 is rotated to drive the second rotating rod 108 to rotate, thereby driving the U-shaped head 109 to rotate. The U-shaped head 109 rotates to drive the docking head 112 to rotate, thereby rotating the shaft on the tool 110, so that the drill bit of the tool 110 rotates.

[0063] Before installing the tool 110, the second sleeve 104 is located between two adjacent mounting holes 113. At the same time, before installing the tool 110, the PLC controller 308 is operated to rotate the second motor 307 and rotate the U-shaped head 109 to a horizontal state, that is, the U-shaped head 109 can dock with the joint 112. This can be controlled by a pre-set program inside the PLC controller 308.
