Description
Technical Field
[0001] This invention relates to the field of milling cutter technology, and in particular to a wedge-block clamping three-sided milling cutter. Background Technology
[0002] Three-sided milling cutters are disc-shaped multi-tooth cutting tools, often simply called three-sided milling cutters. The cutter body is made of high-speed steel or cemented carbide, with a clamping hole in the center. The main cutting edge is located on the circumferential surface, and secondary cutting edges are located near the outer edge on both end faces. All three edges have a clearance angle and sharp cutting edges. They are available in straight tooth and staggered tooth types. Staggered tooth cutting is smoother and has better chip removal. They are mainly used on horizontal milling machines and can mill fixed-value grooves and stepped surfaces in one pass, with high groove width accuracy and low surface roughness.
[0003] Chinese invention patent CN1287938C discloses a three-sided milling cutter with adjustable milling width, comprising a disk with chip grooves spaced around its periphery, left and right tool holders, a pressure block, a double-ended bolt, a cutting insert, and a screw for fixing the cutting insert, all placed in the chip grooves. Each tool holder has a groove on its serrated surface that is similar to a keyway at a certain angle to the side of the tool holder. One end of a drive pin is mounted on a pin that can move along a radial hole on the disk, while the other end is mounted in the groove of the tool holder. By adjusting the screw, the pin drives the drive pin to move along the serrated surface of the chip groove, which is converted into the axial movement of the cutting insert driven by the tool holder, thereby adjusting the width of the cutting edge of the entire milling cutter and ultimately adjusting the width of the machined groove.
[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: When adjusting the overall width of the milling cutter, it is necessary to first loosen multiple bolts on the milling cutter to allow the pressure block to lose its squeezing of the cutting edge, and then turn the screws on the corresponding cutting edge positions one by one to adjust the cutting edge positions, which makes the overall operation cumbersome and makes it difficult to guarantee the accuracy of each cutting edge adjustment. Summary of the Invention
[0005] To address the aforementioned problems, this invention provides a wedge-type clamping three-sided milling cutter.
[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a wedge-block clamping three-sided milling cutter, comprising a disc body and a plurality of seats fixed on the disc body, wherein a first cutter and a second cutter are respectively provided on both sides of the seats, and a connecting mechanism is provided on the disc body, the connecting mechanism comprising a moving component, wherein the moving component comprises a first seat and a second seat provided on both sides of the seats and a plurality of locking teeth fixed on the first cutter and the second cutter, wherein the first seat and the second seat are provided with tooth grooves for the locking teeth to engage, and the connecting mechanism further comprises a locking component for locking the first cutter and the second cutter and an adjusting component for releasing the locking component and controlling the first seat and the second seat to move in opposite directions.
[0007] By adopting the above technical solution, during use, blade one and blade two can be placed on base one and base two respectively. The surface locking teeth can be inserted into the tooth grooves to limit the position of blade one and blade two. Then, the locking component is used to lock blade one and blade two, and then work can begin. When it is necessary to adjust the working width, the adjusting component first controls the locking component to loosen, and then controls base one and base two to move in opposite directions, thereby adjusting the position of blade one and blade two. The overall operation is more convenient and improves the accuracy of adjusting each set of blade one and blade two.
[0008] Furthermore, the locking teeth are made of magnets, and both the first and second seats are magnetic seats. The locking teeth are initially positioned by magnetic attraction with the first and second seats.
[0009] By adopting the above technical solution, when the locking tooth is inserted into the tooth groove, the locking tooth is magnetically attracted to seat one and seat two, thereby initially positioning knife one and knife two, which facilitates subsequent stable adjustment.
[0010] Furthermore, the surface of the disc body is provided with multiple assembly holes, and the locking component includes multiple wedge blocks respectively disposed between two seats. The surface of the wedge blocks is provided with locking holes. The locking component also includes a bolt sleeve inserted into the locking hole and a screw rod slidably connected in the assembly hole and threadedly connected to the bolt sleeve.
[0011] By adopting the above technical solution, during the locking process, the bolt sleeve can be inserted into the locking hole on the surface of the wedge block, and then the bolt sleeve is threadedly connected to the screw. The bolt sleeve can fit against the inner wall of the locking hole, drive the wedge block to move, and press the wedge block. The wedge block can fit against the first and second blades, locking the first and second blades. The adjusting component can control the screw to slide in the assembly hole, thereby controlling the bolt sleeve to loosen or press the wedge block.
[0012] Furthermore, the bolt sleeve includes a clamping section and a threaded connection section, the threaded connection section being threadedly connected to the screw, and the clamping section having a tapered structure.
[0013] By adopting the above technical solution, the threaded connection section in the bolt sleeve is used to connect with the screw thread, thereby driving the pressing section of the tapered structure to press the wedge block.
[0014] Furthermore, the surface of the disc body is provided with multiple guide grooves, and the locking component also includes two guide rods fixed to the lower surface of the wedge block, the guide rods being inserted into the inner wall of the guide groove.
[0015] By adopting the above technical solution, when the bolt is threadedly connected to the screw and drives the wedge block to move, the guide rod can slide in the guide groove, thereby guiding the wedge block and ensuring stability.
[0016] Furthermore, the surfaces of both the base and the disc are provided with multiple insertion holes, and the surface of the base is provided with a through hole. The adjusting component includes a shaft inserted into the insertion hole, a connecting rod provided in the through hole, two protrusions respectively fixed on base one and base two and slidably connected to the inner wall of the through hole, and a roller fixed in the inner wall of the protrusion. The surface of the connecting rod is provided with a spline hole for the shaft to be inserted, and the surface of the connecting rod is provided with two control grooves that are slidably connected to the roller. The adjusting component also includes an adjusting assembly for controlling the rotation of the shaft and the movement of the screw.
[0017] By adopting the above technical solution, during use, the adjusting component first drives the screw to move, thereby controlling the bolt sleeve to loosen the pressure on the wedge block. Then, the adjusting component drives the shaft to rotate. The shaft, in conjunction with the spline hole, can drive the connecting rod to rotate. When the connecting rod rotates, the two control grooves on the surface cooperate with the roller and the protrusion, which can drive seat one and seat two to move in different directions.
[0018] Furthermore, the surface of the disc body is provided with a groove, and the adjustment assembly includes a first bevel gear fixedly sleeved on the shaft and a second bevel gear rotatably connected in the groove and meshing with the first bevel gear.
[0019] By adopting the above technical solution, when making adjustments, bevel gear two can be rotated, which can drive multiple bevel gears one to rotate. The bevel gears one synchronously drive the shaft to rotate, thus realizing synchronous control operation of multiple shafts.
[0020] Furthermore, the adjustment assembly also includes a worm gear fixed on the second bevel gear, two hollow seats fixed in the groove, a worm rotatably connected between the two hollow seats and meshing with the worm gear, a third bevel gear fixedly sleeved on the worm, and a fourth bevel gear rotatably connected in the hollow seats and meshing with the third bevel gear.
[0021] By adopting the above technical solution, during the adjustment process, bevel gear four can drive bevel gear three and worm to rotate. The worm, in conjunction with the worm wheel, can drive bevel gear two to rotate, achieving synchronous adjustment. The worm, in conjunction with the worm wheel, can achieve self-locking, further improving the stability effect after adjustment.
[0022] Furthermore, the inner wall of the disc body is provided with multiple sliding grooves. The adjustment assembly also includes a slider slidably connected in the sliding groove, a rod fixed on the surface of the slider, a ring fixed on the rod, and a control head and push rod rotatably connected to the disc body. The surface of the slider is provided with interconnected straight holes and oblique holes. The surface of the screw is provided with a rectangular hole. The surface of the second bevel gear is provided with multiple through holes for the rod to pass through. The control head passes through the fourth bevel gear and is slidably connected to the fourth bevel gear. The adjustment assembly also includes an auxiliary rod fixed in the rectangular hole and slidably connected to the straight hole and oblique hole, and a spring fixed between the slider and the inner wall of the sliding groove.
[0023] By adopting the above technical solution, the corresponding tool can be inserted into the control head, and then the control head and push rod can be pushed. The control head and push rod drive the ring, rod body and slider to move synchronously. When the slider moves, the spring is stressed, and the auxiliary rod enters the inclined hole from the straight hole. The inclined hole and the auxiliary rod can drive the screw to move upward, thereby releasing the pressure on the wedge block. After the release, the spring can drive the slider to reset, and the auxiliary rod re-enters the straight hole to limit the screw, thereby locking it.
[0024] Furthermore, a cover plate is provided on the side of the disc body near the groove body. The cover plate is installed on the disc body by screws, and the surface of the cover plate has a round hole for the control head and push rod to pass through.
[0025] By adopting the above technical solution, the cover plate can be installed on the disc body with screws, which can seal the tank and reduce the amount of waste entering the tank.
[0026] In summary, the present invention has the following beneficial effects: 1. In this application, blade one and blade two engage with the toothed grooves of base one and base two through the toothed teeth on their surfaces. Then, blade one and blade two are locked by a locking component. During adjustment, the locking component first loosens the locking component, and then the adjusting component can drive base one and base two to move in the opposite direction to adjust the overall machining width, adapting to machining requirements of various widths. Compared with the cumbersome process of adjusting the blade position one by one in the traditional adjustment method, the adjustment efficiency is greatly improved, and the consistency of the adjustment position of each set of blade one and blade two can be better guaranteed. This effectively reduces the deviation caused by individual adjustment and further improves the uniformity and accuracy of machining dimensions. 2. In this application, by setting a locking component, a locking structure of wedge block with bolt sleeve and screw is adopted. The pressing section of bolt sleeve is designed as a conical structure, which fits tightly with the locking hole of wedge block. When connected with screw, it can drive wedge block to move smoothly, forming a uniform and firm clamping force on tool one and tool two, reducing tool loosening and deviation during cutting. At the same time, the cooperation between guide rod and guide groove plays a precise guiding role in the movement of wedge block, reducing wedge block deviation that may cause locking failure. 3. In this application, by setting an adjustment component, the ring, rod and slider can be moved synchronously by the control head and push rod. The auxiliary rod enters the inclined hole from the straight hole, thereby driving the screw and bolt sleeve to move and release the pressure on the wedge block. Then the control head drives the fourth bevel gear to rotate. The fourth bevel gear cooperates with the third bevel gear, worm, worm wheel, second bevel gear and first bevel gear to drive the shaft to rotate. The shaft cooperates with the connecting rod, control groove, protrusion and roller to drive the first seat and the second seat to move in opposite directions to realize the adjustment operation.

Multiple base bodies 2 are provided and fixed to the disc body 1. The first cutter 3 and the second cutter 4 are respectively disposed on both sides of the base body 2, and the connecting mechanism 5 is disposed on the disc body 1. The connecting mechanism 5 includes a moving component 51, a locking component 52, and an adjusting component 53. The moving component 51 includes a first base 511, a second base 512, and locking teeth 513. The first base 511 and the second base 512 are disposed on both sides of the base body 2, and multiple locking teeth 513 are provided and fixed to the first cutter 3 and the second cutter 4. The first base 511 and the second base 512 are provided with tooth grooves 6 for the locking teeth 513 to engage. During use, blade 3 and blade 4 can be placed on base 511 and base 512 respectively. The locking teeth 513 on the surface can be inserted into the tooth groove 6 to limit the position of blade 3 and blade 4. Then, the locking component 52 is used to lock blade 3 and blade 4, and the work can be started. When it is necessary to adjust the working width, the adjusting component 53 first controls the locking component 52 to loosen, and then controls base 511 and base 512 to move in opposite directions, thereby adjusting the position of blade 3 and blade 4. The overall operation is more convenient and improves the accuracy of adjusting each set of blade 3 and blade 4.
[0031] The locking tooth 513 is made of magnet, and both seat 1 511 and seat 2 512 are magnetic seats. The locking tooth 513 achieves initial positioning by magnetic attraction with seat 1 511 and seat 2 512. After the locking tooth 513 is inserted into the tooth groove 6, the locking tooth 513 is magnetically attracted with seat 1 511 and seat 2 512, thereby initially positioning knife 1 3 and knife 2 4, which facilitates subsequent stable adjustment.
[0032] The surface of the disc body 1 has multiple mounting holes 7. A locking component 52 is used to lock the first knife 3 and the second knife 4. The locking component 52 includes wedge blocks 521. Multiple wedge blocks 521 are provided, and each wedge block 521 is respectively disposed between two seats 2. The surface of the wedge blocks 521 has locking holes 17. The locking component 52 also includes a bolt sleeve 522 and a screw 523. The bolt sleeve 522 is inserted into the locking hole 17, and the screw 523 is slidably connected to the mounting hole 7 and threadedly connected to the bolt sleeve 522. During the locking process, the bolt sleeve 522 can be inserted into the locking hole 17 on the surface of the wedge block 521. Then, the bolt sleeve 522 is threadedly connected to the screw 523. The bolt sleeve 522 can fit against the inner wall of the locking hole 17, driving the wedge block 521 to move and pressing the wedge block 521. The wedge block 521 can fit against the first knife 3 and the second knife 4, locking the first knife 3 and the second knife 4. The adjusting component 53 can control the screw 523 to slide in the assembly hole 7, thereby controlling the bolt sleeve 522 to loosen or press the wedge block 521.
[0033] The bolt sleeve 522 includes a clamping section and a threaded connection section. The threaded connection section is threadedly connected to the screw 523, and the clamping section has a tapered structure. The threaded connection section in the bolt sleeve 522 is used to connect with the screw 523, thereby driving the tapered clamping section to clamp the wedge block 521.
[0034] The surface of the disc body 1 has multiple guide grooves 8, and the locking component 52 also includes guide rods 524. Two guide rods 524 are provided, and both guide rods 524 are fixed to the lower surface of the wedge block 521. The guide rods 524 are inserted into the inner wall of the guide grooves 8. When the bolt sleeve 522 is threadedly connected to the screw 523 and drives the wedge block 521 to move, the guide rods 524 can slide in the guide grooves 8, thereby guiding the wedge block 521 and ensuring stability.
[0035] Both the base 2 and the disc 1 have multiple insertion holes 11 on their surfaces, and the base 2 has through holes 10 on its surface. An adjusting component 53 releases the locking component 52 and controls the reverse movement of base 1 511 and base 2 512. The adjusting component 53 includes a shaft 531, a connecting rod 532, a protrusion 533, a roller 535, and an adjusting assembly. The shaft 531 is inserted into the insertion hole 11, and the connecting rod 532 is disposed in the through hole 10. Two protrusions 533 are provided, respectively fixed to base 1 511 and base 2 512 and slidably connected to the inner wall of the through hole 10. The roller 535 is fixed in the inner wall of the protrusion 533. The surface of the connecting rod 532 has a spline hole 18 for the shaft 531 to be inserted, and two control grooves 9 are formed on the surface of the connecting rod 532 that are tactilely connected to the roller 535. During use, the adjusting component first moves the screw 523, thereby controlling the bolt sleeve 522 to loosen its pressure on the wedge block 521. Then, the adjusting component drives the shaft 531 to rotate. The shaft 531, in conjunction with the spline hole 18, can drive the connecting rod 532 to rotate. When the connecting rod 532 rotates, the two control grooves 9 on its surface cooperate with the roller 535 and the protrusion 533, which can drive the seat 1 511 and seat 2 512 to move in different directions.
[0036] The surface of the disc body 1 has a groove 16. The adjustment assembly includes a first bevel gear 536 and a second bevel gear 537. The first bevel gear 536 is fixedly sleeved on the shaft 531, and the second bevel gear 537 is rotatably connected in the groove 16 and meshes with the first bevel gear 536. During adjustment, the second bevel gear 537 can be rotated, which can drive multiple first bevel gears 536 to rotate. The first bevel gears 536 synchronously drive the shaft 531 to rotate, realizing synchronous control operation of multiple shafts 531.
[0037] The adjusting assembly controls the rotation of shaft 531 and the movement of screw 523. The adjusting assembly also includes a worm gear 538, a hollow seat 539, a worm 534, a third bevel gear 5310, and a fourth bevel gear 5311. The worm gear 538 is fixed to the second bevel gear 537. Two hollow seats 539 are provided and fixed within the groove 16. The worm 534 is rotatably connected between the two hollow seats 539 and meshes with the worm gear 538. The third bevel gear 5310 is fixedly sleeved on the worm 534. The fourth bevel gear 5311 is rotatably connected inside the hollow seat 539 and meshes with the third bevel gear 5310. During the adjustment process, the fourth bevel gear 5311 can drive the third bevel gear 5310 and the worm 534 to rotate. The worm 534, in conjunction with the worm wheel 538, can drive the second bevel gear 537 to rotate, achieving synchronous adjustment. The worm 534, in conjunction with the worm wheel 538, can achieve self-locking, further improving the stability after adjustment.
[0038] The inner wall of the disc body 1 has multiple sliding grooves 12. The adjustment assembly also includes a slider 5312, a rod 5313, a ring 5314, a control head 5317, and a push rod 5318. The slider 5312 is slidably connected in the sliding groove 12, and the surface of the slider 5312 has interconnected straight holes 19 and oblique holes 20. The rod 5313 is fixed to the surface of the slider 5312, and the surface of the bevel gear 537 has multiple through holes 13 for the rod 5313 to pass through. The ring 5314 is fixed to the rod 5313, and the control head 5317 and the push rod 5318 are rotatably connected to the disc body 1. The screw 523 has a rectangular hole 14 on its surface.

The auxiliary rod 5316 is fixed in the rectangular hole 14 and is slidably connected to the straight hole 19 and the inclined hole 20. The spring 5315 is fixed between the slider 5312 and the inner wall of the groove 12. The corresponding tool can be inserted into the control head 5317, and then the control head 5317 and push rod 5318 are pushed. The control head 5317 and push rod 5318 drive the ring 5314, rod 5313 and slider 5312 to move synchronously. When the slider 5312 moves, the spring 5315 is stressed, and the auxiliary rod 5316 enters the inclined hole 20 from the straight hole 19. The inclined hole 20, in conjunction with the auxiliary rod 5316, can drive the screw 523 to move upward, thereby releasing the pressure on the wedge block 521. After the release, the spring 5315 can drive the slider 5312 to reset, and the auxiliary rod 5316 re-enters the straight hole 19 to limit the screw 523, thereby locking it.
[0039] A cover plate 15 is provided on the side of the disc body 1 near the tank body 16. The cover plate 15 is installed on the disc body 1 by screws. The surface of the cover plate 15 has a round hole for the control head 5317 and the push rod 5318 to pass through. By installing the cover plate 15 on the disc body 1 by screws, the tank body 16 can be sealed, reducing the amount of waste entering the tank body 16.
[0040] The working principle of the wedge-block clamping three-sided milling cutter in this embodiment is as follows: During installation, the retaining teeth 513 on the surfaces of cutter 3 and cutter 4 are first installed in the tooth grooves 6 on the surfaces of seat 1 511 and seat 2 512, respectively. After multiple cutters 3 and 4 are installed, the wedge block 521 is placed between cutters 3 and 4, and the bolt sleeve 522 is inserted into the locking hole 17 on the surface of the wedge block 521, so that the bolt sleeve 522 is threadedly connected to the screw 523, thereby driving the wedge block 521 to move, and the two sides of the wedge block 521 are squeezed. With the cooperation of base 1 (3) and base 2 (4), the cutter 3 and cutter 4 are clamped together, allowing for cutting operations. When the machining width needs to be adjusted, the corresponding tool is first inserted into the control head (5317), and then the control head (5317) and push rod (5318) are pushed. The control head (5317) and push rod (5318) drive the ring (5314), rod (5313), and slider (5312) to move synchronously. When the slider (5312) moves, the spring (5315) is stressed, and the auxiliary rod (5316) enters the inclined hole (20) from the straight hole (19). The inclined hole 20, in conjunction with the auxiliary rod 5316, can drive the screw 523 to move upward, thereby releasing the clamping of the wedge block 521. At this time, by rotating the control head 5317, the control head 5317 drives the fourth bevel gear 5311 to rotate. The fourth bevel gear 5311 drives the third bevel gear 5310 and the worm gear 534 to rotate. The worm gear 534, in conjunction with the worm wheel 538, can drive the second bevel gear 537 to rotate. The second bevel gear 537 can drive multiple first bevel gears 536 to rotate. The first bevel gears 536 synchronously drive the shaft. When 531 rotates, the shaft 531, in conjunction with the spline hole 18, can drive the connecting rod 532 to rotate. When the connecting rod 532 rotates, the two control grooves 9 on its surface, in conjunction with the roller 535 and the protrusion 533, can drive the seat 1 511 and seat 2 512 to move in different directions. After adjustment, the control head 5317 and the push rod 5318 are released, the spring 5315 drives the slider 5312 to reset, allowing the auxiliary rod 5316 to enter the straight hole 19 and lock the screw 523. The bolt sleeve 522 continues to press the wedge block 521.
