Description

Technical Field

[0001] This invention relates to a special machine tool for grinding cutting edges, belonging to the field of machine tool technology. Background Technology

[0002] A milling cutter is a rotating cutting tool with one or more cutting teeth used for milling operations. During operation, the cutting teeth sequentially and intermittently remove the excess material from the workpiece. Milling cutters are mainly used on milling machines to machine planes, steps, grooves, shaped surfaces, and cut off workpieces.

[0003] Currently, when machining milling cutters, the grinding process is often carried out in steps on different machine tools, such as external cylindrical grinding machines and end face grinding machines, which results in low machining efficiency for milling cutters.

[0004] Therefore, a new solution is needed to address this problem. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a special machine tool for grinding cutting edges, which solves the problem that in the prior art, the grinding process of milling cutters is often carried out in steps on different machine tools, such as external cylindrical grinding machines and end face grinding machines, which leads to low processing efficiency of milling cutters.

[0006] The technical problem to be solved by the present invention is achieved by the following technical solution: a special machine tool for edge grinding, comprising a machine body, wherein a stepping feeding assembly, a machining assembly, and an unloading assembly are respectively arranged on the machine body, the machining assembly includes a roughing assembly and a finishing assembly, and a turntable rotatably connected to the machine body, the roughing assembly includes a rough external cylindrical grinder and a rough end face grinder, the finishing assembly includes a fine external cylindrical grinder and a fine end face grinder, and a plurality of clamping seats for clamping milling cutters are arranged in an array along the circumferential direction on the outer peripheral wall of the turntable, the rough external cylindrical grinder, the rough end face grinder, the fine external cylindrical grinder, and the fine end face grinder are equally spaced on the outer side of the turntable, and both the stepping feeding assembly and the unloading assembly include clamping mechanisms for clamping milling cutters.

[0007] By adopting the above technical solution, and by equally spaced rough cylindrical grinding machines, rough end face grinding machines, fine cylindrical grinding machines, and fine end face grinding machines on the outer side of the turntable, when machining milling cutters, the milling cutters are first loaded by a stepping feeding assembly, then clamped by a clamping mechanism and transported to the clamping seat of the turntable. The turntable then rotates, causing the milling cutters on the clamping seat to move to the rough cylindrical grinding machine for machining. At the same time, the clamping mechanism continues to clamp the milling cutters to the clamping seat. After the rough machining of the outer diameter of the milling cutter is completed, the turntable continues to rotate until each milling cutter has completed the machining of the rough end face grinding machine, the fine cylindrical grinding machine, and the fine end face grinding machine in sequence. Finally, the machined milling cutters are collected under the clamping mechanism on the unloading assembly. This integrates the operation of cylindrical grinding machines and end face grinding machines on one machine, which is very convenient to use and greatly improves efficiency.

[0008] The present invention is further configured such that: the stepping feeding assembly includes a feeding box, an adjustment mechanism for adjusting the position of the milling cutter, and a conveying mechanism for transporting the milling cutter to the clamping seat position; a plurality of feeding plates 1 are slidably connected in the vertical direction through a connecting seat in the feeding box; feeding plates 2 are staggered between adjacent feeding plates 1; a plurality of feeding grooves are inclinedly opened on both feeding plates 1 and feeding plates 2; and a sliding power source for driving the connecting seat to slide is provided at the bottom of the feeding box.

[0009] By adopting the above technical solution, when feeding the milling cutter, it is only necessary to pour the milling cutter into the feeding box. The milling cutter will eventually stop on the surface of the feeding groove of the feeding plate one. Then, the connecting seat is driven to slide up and down by the sliding power source, so that the feeding plate one can slide up and down between the feeding plates two, thereby realizing the step feeding of the milling cutter. The specific operation is as follows: Since the feeding groove is inclined and the feeding plates one and two are staggered, in the initial state, the milling cutter is limited by the inner wall of the feeding groove of the feeding plate two, so it cannot roll into the interior of the feeding plate one. When the feeding plate one is higher than the feeding plate two, the milling cutter is released from the limitation of the feeding plate two, and rolls to the innermost part of the feeding groove. When the feeding plate falls and is lower than the feeding plate two, the milling cutter will again abut against the inner wall of the feeding groove of the feeding plate two and roll down to the deepest part. This process is repeated until the clamping mechanism clamps the milling cutter, thus realizing the step feeding operation of the step feeding component.

[0010] The invention is further configured such that: the adjustment mechanism includes a mounting base disposed on the side wall of the loading box, an electric push rod disposed on the mounting base, an adjustment cylinder disposed at one end of the electric push rod, an aiming frame for the adjustment cylinder to be engaged on one side of the mounting base, a connecting plate disposed on the loading box, a limiting frame aligned with the aiming frame disposed on the connecting plate, a limiting mechanism for abutting the milling cutter disposed within the limiting frame, the limiting mechanism including a limiting seat, and a pressure plate driven above the limiting seat by a limiting cylinder.

[0011] By adopting the above technical solution, after the clamping mechanism clamps the milling cutter, it is sent to the upper part of the limiting seat inside the limiting frame. Then, the limiting cylinder presses down the pressure plate to prevent the milling cutter from moving vertically. Then, the electric actuator is activated, so that the adjusting cylinder passes through the aiming frame and abuts against the end of the milling cutter. The milling cutter gradually retracts under the thrust of the adjusting cylinder. After the adjusting cylinder moves to the set stroke, it stops moving. Then, the clamping mechanism clamps the milling cutter. Thus, when the clamping mechanism clamps the milling cutter onto the clamping seat, the clamping seat can accurately clamp the milling cutter at the specified position. This allows the part of the milling cutter to be machined to be accurately aligned with the roughing and finishing components, thereby effectively improving the machining quality of the product.

[0012] The invention is further configured such that: the clamping mechanism includes a mounting plate and a sliding seat connected to the conveying mechanism; both sides of the bottom of the mounting plate are slidably connected to sliders with a T-shaped cross-section; clamping blocks are provided on the opposite sides of the two sliders; a plurality of V-shaped clamping blocks are provided on the clamping blocks; a clamping cavity is formed between the V-shaped clamping blocks of the two clamping blocks; a mounting frame is provided between the sliding seat and the mounting plate; a driving cylinder is provided inside the mounting frame; a rotating shaft is provided on both sides inside the mounting frame; a crank arm is rotatably connected to the rotating shaft; one end of the crank arm is rotatably connected to the piston rod of the driving cylinder; and the other end passes through the mounting plate and is inserted into the slider.

[0013] By adopting the above technical solution, when clamping the milling cutter, it is only necessary to move the piston rod of the drive cylinder upward, which drives the crank arm to rotate. This causes the end of the crank arm that is inserted into the slider to rotate and causes the slider to slide at the bottom of the mounting plate. In turn, it causes the two clamping blocks and the V-shaped clamping block to move closer to each other, thus completing the clamping operation of the milling cutter. The operation is convenient and stable.

[0014] The present invention is further configured such that: both the rough cylindrical grinding machine and the fine cylindrical grinding machine include a base, a longitudinal sliding seat is slidably connected to the base, a transverse sliding seat is slidably connected to the longitudinal sliding seat, a fixed seat is rotatably connected to the transverse sliding seat in a direction perpendicular to the surface of the transverse sliding seat, and a grinding element is rotatably connected to the fixed seat in a direction parallel to the top surface of the fixed seat.

[0015] By adopting the above technical solution, the setting of the longitudinal sliding seat 1 and the transverse sliding seat 1 allows the grinding part 1 to move in the longitudinal and transverse directions, while the fixed seat 1 can rotate in a direction perpendicular to the surface of the transverse sliding seat 1, and the grinding part 1 can rotate in a direction parallel to the top surface of the fixed seat 1, so that the grinding part 1 can also adjust its grinding angle on the milling cutter, and the grinding range of the milling cutter is more extensive.

[0016] The present invention is further configured such that: both the rough end face grinding machine and the fine end face grinding machine include a base two, the base two is slidably connected to a transverse sliding seat two, the transverse sliding seat two is slidably connected to a longitudinal sliding seat two, the longitudinal sliding seat two is provided with a fixed seat two, and the fixed seat two is slidably connected to a grinding element two along the vertical direction.

[0017] By adopting the above technical solution, the setting of the longitudinal sliding seat 2 and the transverse sliding seat 2 allows the grinding part 2 to move in the longitudinal and transverse directions, while the grinding part 2 can slide along the vertical direction of the fixed seat 2, so that the grinding part 2 can move in the vertical direction, and the grinding part 2 can also adjust its grinding height on the milling cutter, which is convenient for processing different surfaces of the milling cutter.

[0018] The present invention is further configured such that: the unloading assembly includes a conveyor belt, a transfer mechanism for transferring the milling cutter onto the conveyor belt, and a collection mechanism for collecting the milling cutter; the transfer mechanism includes a connecting frame fixed on the machine body; a slide is laterally fixed on the connecting frame; a slide block is slidably connected inside the slide block; and the bottom of the slide block is connected to the clamping mechanism via a transfer cylinder.

[0019] By adopting the above technical solution, after the milling cutter is finished, it is clamped by the clamping mechanism, and then transferred to the conveyor belt by the transfer mechanism and conveyed until it falls into the collection mechanism, which facilitates the collection of the milling cutter. The carriage and slide block are designed to allow the clamping mechanism to slide in the lateral direction, and the transfer cylinder is designed to allow the clamping mechanism to move in the vertical direction, thereby achieving the clamping effect of the clamping mechanism on the milling cutter.

[0020] The present invention is further configured such that: the collection mechanism includes a collection seat, a collection rack is inclinedly arranged on the surface of the collection seat, a collection plate is arranged on the top of the collection rack, a plurality of collection baskets are arranged at equal intervals on the surface of the collection plate, a collection cylinder is arranged on one side of the collection rack, and the piston rod of the collection cylinder is fixed to the bottom of the collection plate.

[0021] By adopting the above technical solution, the milling cutter will fall into the collection basket after falling off the conveyor belt. The collection basket makes it more convenient for workers to collect the milling cutter. Then, when one collection basket is full, the collection cylinder drives the collection plate to move, so that the other collection basket will move under the conveyor belt to continue receiving materials.

[0022] The present invention is further configured such that: a guide plate is inclinedly provided at one end of the conveyor belt, and both ends of the guide plate are provided with retaining edges, and the inner diameter of the guide plate gradually decreases in the direction away from the conveyor belt.

[0023] By adopting the above technical solution, the milling cutter, after falling from the conveyor belt, will slide onto the collection basket under the guidance of the guide plate, and the setting of the guard edge will prevent the milling cutter from falling outside the guide plate, making the conveying process more stable.

[0024] The present invention is further configured such that: the conveying mechanism includes a conveying seat, a conveying frame is slidably connected to the side wall of the conveying seat along the length direction, a conveying plate is slidably connected to the conveying frame along the vertical direction, the conveying plate is connected to the sliding seat, a conveying motor is provided on the side wall of the conveying seat, and a screw threadedly connected to the conveying frame is fixed at the output end of the conveying motor.

[0025] By adopting the above technical solution, when it is necessary to drive the clamping mechanism to slide, it is only necessary to drive the screw to rotate through the conveyor motor, thereby driving the conveyor frame that is threadedly connected to the screw to slide, thus achieving the lateral movement effect of the clamping mechanism.

[0026] The beneficial effects of this invention are as follows: By equidistantly distributing rough cylindrical grinding machines, rough end face grinding machines, fine cylindrical grinding machines, and fine end face grinding machines on the outer side of the turntable, when machining milling cutters, the milling cutters are first loaded via a stepping feeding assembly, then clamped by a clamping mechanism and transported to the clamping seat of the turntable. The turntable then rotates, causing the milling cutters on the clamping seat to move to the rough cylindrical grinding machine for machining. Simultaneously, the clamping mechanism continues to clamp the milling cutters onto the clamping seat. After the rough machining of the outer diameter of the milling cutter is completed, the turntable continues to rotate until each milling cutter has sequentially completed the machining of the rough end face grinding machine, the fine cylindrical grinding machine, and the fine end face grinding machine. Finally, the machined milling cutters are collected under the clamping mechanism on the unloading assembly. This integrates the operation of cylindrical grinding machines and end face grinding machines on a single device, making it very convenient to use and greatly improving efficiency.

[0037] To facilitate a clear understanding of the technical means, creative features, objectives, and effects of this invention, the invention will be further described below in conjunction with specific illustrations.

[0038] like Figure 1 As shown, a special machine tool for grinding cutting edges includes a machine body 1, on which a stepping feeding assembly 2, a processing assembly, and a unloading assembly 6 are respectively arranged. The stepping feeding assembly 2 and the unloading assembly 6 both include a clamping mechanism 21 for clamping the milling cutter.

[0039] like Figure 6 and Figure 7 As shown, the machining components include a roughing component 3, a finishing component 4, and a turntable 5 rotatably connected to the machine body 1. The roughing component 3 includes a rough external cylindrical grinder 31 and a rough end face grinder 32. The finishing component 4 includes a fine external cylindrical grinder 41 and a fine end face grinder 42. Several clamping seats 51 for holding milling cutters are arranged in an array along the circumferential direction on the outer peripheral wall of the turntable 5. The rough external cylindrical grinder 31, the rough end face grinder 32, the fine external cylindrical grinder 41, and the fine end face grinder 42 are distributed at equal intervals on the outer side of the turntable 5.

[0040] By equidistantly distributing rough cylindrical grinding machine 31, rough end face grinding machine 32, fine cylindrical grinding machine 41, and fine end face grinding machine 42 on the outer side of the turntable 5, when machining milling cutters, the milling cutter is first loaded by the stepping feeding assembly 2, then clamped by the clamping mechanism 21 and transported to the clamping seat 51 of the turntable 5. The turntable 5 is then rotated, causing the milling cutter on the clamping seat 51 to move to the rough cylindrical grinding machine 31 for machining. At the same time, the clamping mechanism 21 continues to clamp the milling cutter to the clamping seat 51. After the rough machining of the outer diameter of the milling cutter is completed, the turntable 5 continues to rotate until each milling cutter has been processed by the rough end face grinding machine 32, the fine cylindrical grinding machine 41, and the fine end face grinding machine 42 in sequence. Finally, the machined milling cutter is collected under the clamping of the clamping mechanism 21 on the unloading assembly 6. This integrates the operation of cylindrical grinding machine and end face grinding machine on one machine, which is very convenient to use and greatly improves efficiency.

[0041] Both the rough cylindrical grinding machine 31 and the fine cylindrical grinding machine 41 include a base 311. A longitudinal sliding seat 312 is slidably connected to the base 311, and a transverse sliding seat 313 is slidably connected to the longitudinal sliding seat 312. A fixed seat 314 is rotatably connected to the transverse sliding seat 313 in a direction perpendicular to its surface. A grinding element 315 is rotatably connected to the fixed seat 314 in a direction parallel to its top surface. The arrangement of the longitudinal sliding seat 312 and the transverse sliding seat 313 allows the grinding element 315 to move longitudinally and laterally. The fixed seat 314 can rotate in a direction perpendicular to the surface of the transverse sliding seat 313, and the grinding element 315 can rotate in a direction parallel to the top surface of the fixed seat 314. This allows the grinding element 315 to adjust its grinding angle on the milling cutter, thus providing a wider range of milling cutter grinding adaptability.

[0042] Both the rough end face grinder 32 and the fine end face grinder 42 include a base 321. A transverse sliding seat 322 is slidably connected to the base 321. A longitudinal sliding seat 323 is slidably connected to the transverse sliding seat 322. A fixed seat 324 is mounted on the longitudinal sliding seat 323. A grinding element 325 is slidably connected to the fixed seat 324 in the vertical direction. The arrangement of the longitudinal sliding seat 323 and the transverse sliding seat 322 allows the grinding element 325 to move longitudinally and laterally. The grinding element 325 can slide along the vertical direction of the fixed seat 324, allowing it to move vertically and adjust its grinding height on the milling cutter, facilitating the machining of different faces of the milling cutter.

[0043] like Figures 2 to 5 As shown, the stepping feeding assembly 2 also includes a feeding box 22, an adjustment mechanism 23 for adjusting the position of the milling cutter, and a conveying mechanism 24 for transporting the milling cutter to the position of the clamping seat 51.

[0044] Inside the feeding box 22, several feeding plates 222 are slidably connected in the vertical direction via connecting seats 221. Feeding plates 223 are staggered between adjacent feeding plates 222. Several feeding slots 224 are inclinedly opened on both feeding plates 222 and feeding plates 223. A sliding power source 225 for driving the connecting seats 221 to slide is provided at the bottom of the feeding box 22. The sliding power source 225 can be a cylinder, electric push rod or other device that can drive the object to move up and down.

[0045] This allows for easy loading of the milling cutter. Simply pour the milling cutter into the loading box 22, and the cutter will eventually rest on the surface of the loading groove 224 of the first loading plate 222. Then, the connecting seat 221 is driven up and down by the sliding power source 225, allowing the first loading plate 222 to slide up and down between the second loading plate 223, thus achieving step-by-step loading of the milling cutter. Specifically, since the loading groove 224 is inclined and the first and second loading plates 222 and 223 are staggered, in the initial state, the milling cutter is loaded by the second loading plate 222... The inner wall of the feeding groove 224 of the 3rd feed cutter is limited, so it cannot roll into the inner part of the feeding plate 1 222. When the feeding plate 1 222 is higher than the feeding plate 223, the milling cutter disengages from the limit of the feeding plate 223 and rolls to the innermost part of the feeding groove 224. When the feeding plate 1 222 falls and is lower than the feeding plate 223, the milling cutter will again abut against the inner wall of the feeding groove 224 of the feeding plate 223 and roll to the deepest part. This process is repeated until the clamping mechanism 21 clamps the milling cutter, thus realizing the step feeding operation of the step feeding component 2.

[0046] like Figure 3As shown, the adjustment mechanism 23 includes a mounting base 231 disposed on the side wall of the feeding box 22. An electric push rod 232 is disposed on the mounting base 231. An adjustment cylinder 233 is disposed at one end of the electric push rod 232. An aiming frame 234 for the adjustment cylinder 233 to be inserted is disposed on one side of the mounting base 231. A connecting plate is disposed on the feeding box 22. A limiting frame 235 aligned with the aiming frame 234 is provided on the connecting plate. A limiting mechanism for abutting the milling cutter is disposed inside the limiting frame 235. The limiting mechanism includes a limiting seat 236. A pressure plate 237 is driven above the limiting seat 236 by a limiting cylinder (not shown in the figure). After the clamping mechanism 21 clamps the milling cutter, it is sent to the limit seat 236 inside the limit frame 235. Then, the limit cylinder presses down the pressure plate 237 to prevent the milling cutter from moving vertically. Then, the electric push rod 232 is activated, so that the adjusting cylinder 233 passes through the aiming frame 234 and abuts against the end of the milling cutter. The milling cutter gradually retracts under the thrust of the adjusting cylinder 233. After the adjusting cylinder 233 moves to the set stroke, it stops moving. Then, the clamping mechanism 21 clamps the milling cutter. Thus, when the clamping mechanism 21 clamps the milling cutter onto the clamping seat 51, the clamping seat 51 can accurately clamp the milling cutter at the specified position. This allows the milling cutter's machining part to be accurately aligned with the roughing component 3 and the finishing component 4, thereby effectively improving the machining quality of the product.

[0047] like Figure 4 and Figure 5 As shown, the clamping mechanism 21 includes a mounting plate 2011 and a sliding seat 2012 connected to the conveying mechanism 24. Sliding blocks 2013 with a T-shaped cross-section are slidably connected to both sides of the bottom of the mounting plate 2011. Clamping blocks 2014 are provided on the opposite sides of the two sliding blocks 2013. Several V-shaped clamping blocks 2015 are provided on the clamping blocks 2014. A clamping cavity 2016 is formed between the V-shaped clamping blocks 2015 of the two clamping blocks 2014. A mounting frame 2017 is provided between the sliding seat 2012 and the mounting plate 2011. A drive cylinder 2018 is provided inside the mounting frame 2017. Rotating shafts 2019 are provided on both sides of the mounting frame 2017. A crank arm 2020 is rotatably connected to the rotating shaft 2019. One end of the crank arm 2020 is rotatably connected to the piston rod of the drive cylinder 2018, and the other end passes through the mounting plate 2011 and is inserted into the sliding block 2013. This design allows for easy and stable operation when clamping the milling cutter. Simply move the piston rod of the drive cylinder 2018 upward to rotate the crank arm 2020, which in turn rotates the end of the crank arm 2020 that is engaged inside the slider 2013. This causes the slider 2013 to slide at the bottom of the mounting plate 2011, which in turn causes the two clamping blocks 2014 and the V-shaped clamping block 2015 to move closer together, thus completing the clamping operation of the milling cutter.

[0048] like Figure 2As shown, the conveying mechanism 24 includes a conveying base 241, a conveying frame 242 slidably connected to the side wall of the conveying base 241 along its length, a conveying plate 243 slidably connected to the conveying frame 242 along its vertical direction, the conveying plate 243 being connected to the sliding base 2012, and a conveying motor 244 being provided on the side wall of the conveying base 241. A screw 245, threadedly connected to the conveying frame 242, is fixed to the output end of the conveying motor 244. When it is necessary to drive the clamping mechanism 21 to slide, the conveying motor 244 simply drives the screw 245 to rotate, thereby causing the conveying frame 242 threadedly connected to the screw 245 to slide, thus achieving the lateral movement effect of the clamping mechanism 21.

[0049] like Figure 8 As shown, the unloading assembly 6 includes a conveyor belt 61, a transfer mechanism 62 for transferring the milling cutter onto the conveyor belt 61, and a collection mechanism 63 for collecting the milling cutter. This allows the milling cutter to be clamped by the clamping mechanism 21 after machining, and then transferred onto the conveyor belt 61 by the transfer mechanism 62 until it falls into the collection mechanism 63, facilitating collection. The carriage 622 and slide block 623 allow the clamping mechanism 21 to slide laterally, while the transfer cylinder 624 allows the clamping mechanism 21 to move vertically, thus achieving the clamping effect of the clamping mechanism 21 on the milling cutter.

[0050] The transfer mechanism 62 includes a connecting frame 621 fixed on the body 1, a slide 622 horizontally fixed on the connecting frame 621, a slide seat 623 slidably connected inside the slide 622, and the bottom of the slide seat 623 is connected to the slide seat 2012 at the top of the clamping mechanism 21 through a transfer cylinder 624.

[0051] The collection mechanism 63 includes a collection seat 631, a collection frame 632 inclinedly arranged on the surface of the collection seat 631, a collection plate 633 on the top of the collection frame 632, and a plurality of collection baskets 634 evenly spaced on the surface of the collection plate 633. A collection cylinder 635 is arranged on one side of the collection frame 632, and the piston rod of the collection cylinder 635 is fixed to the bottom of the collection plate 633. This allows milling cutters to fall into the collection baskets 634 after falling from the conveyor belt 61. The collection baskets 634 make it more convenient for workers to collect milling cutters. When one collection basket 634 is full, the collection cylinder 635 drives the collection plate 633 to move, causing another collection basket 634 to move below the conveyor belt 61 to continue receiving materials.

[0052] A guide plate 611 is inclined at one end of the conveyor belt 61, and both ends of the guide plate 611 are provided with retaining edges 612. The inner diameter of the guide plate 611 gradually decreases in the direction away from the conveyor belt 61. This allows the milling cutter to slide onto the collection basket 634 after falling from the conveyor belt 61 through the guiding action of the guide plate 611, while the retaining edges 612 prevent the milling cutter from falling outside the guide plate 611, making the conveying process more stable.

[0053] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of the invention, all of which fall within the scope of protection claimed by the present invention. The scope of protection of the present invention is defined by the appended claims and their equivalents.
