Description

Technical Field

[0001] This invention belongs to the field of CNC machine tool technology, and specifically relates to a tool clamping device for CNC machine tools. Background Technology

[0002] CNC machine tools are mainly used for cutting and machining shaft-type or disc-type parts, including inner and outer cylindrical surfaces, inner and outer conical surfaces with arbitrary cone angles, complex rotating inner and outer curved surfaces, and cylindrical and conical threads. They can also perform grooving, drilling, reaming, boring, and other machining operations. CNC machine tools can automatically process parts according to a pre-programmed machining program. Operators pre-program the machining process route, process parameters, tool movement trajectory, displacement, cutting parameters, and auxiliary functions of the parts according to the instruction codes and program format specified by the CNC machine tool. The contents of the machining program are then recorded on the control medium and input into the CNC device of the CNC machine tool, thereby directing the machine tool to process the parts.

[0003] When existing CNC machine tool clamping devices clamp CNC machine tool tools, they generally clamp from one side, which limits the clamping capacity. The CNC machine tool tools are prone to move during operation, affecting the normal processing. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a tool clamping device for CNC machine tools. This device can fix the tool from multiple directions, ensuring that the tool remains stable during the operation of the CNC machine tool. The drive mechanism, pull rod, lower pressure plate, and inclined plate, together with the side wall of the first mounting groove, can fix the tool and prevent it from shaking or shifting during operation, thus greatly ensuring the safety and stability of the tool during operation.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A tool clamping device for CNC machine tools includes a mounting rod with a first mounting slot, a second mounting slot, and a third mounting slot inside the mounting rod, arranged sequentially from right to left. A material feeder is disposed in the second mounting slot, and clamping components are installed in the first and third mounting slots. The tool is disposed in the first mounting slot, and the clamping components are used to fix the tool in the first mounting slot. The clamping components include a drive mechanism, a pull rod, a lower pressure plate, and an inclined plate. The drive mechanism is installed in the third mounting slot. The two ends of the pull rod are rotatably connected to the drive mechanism and the lower pressure plate, respectively. The inclined plate is fixedly installed on the top of the lower pressure plate and is inclined upward along the direction away from the first mounting slot. The lower pressure plate cooperates with the side of the tool.

[0007] Preferably, a vertical plate is also installed on the top of the lower pressure plate, and an oblong hole is opened on the vertical plate. A fixing column is fixedly installed on one end of the pull rod. The fixing column is slidably arranged in the oblong hole. The vertical plate and the oblong hole can ensure that the lower pressure plate can squeeze the tool while moving, thereby achieving the purpose of fixing the tool and greatly ensuring the safety and stability of the tool during operation.

[0008] Preferably, a first sliding groove and a second sliding groove are formed on the side wall of the first mounting groove. The first sliding groove and the second sliding groove are arranged in a stepped manner. The first sliding groove is slidably engaged with the inclined plate, and the second sliding groove is slidably engaged with the lower pressure plate. The first sliding groove and the second sliding groove can guide the inclined plate and the lower pressure plate, prevent the lower pressure plate and the inclined plate from shaking during operation, and ensure that the lower pressure plate and the inclined plate cooperate with each other to fix the tool in the first mounting groove.

[0009] Preferably, four pull rods, four pressure plates, and four inclined plates are provided. The four pull rods, four pressure plates, and four inclined plates are respectively located on the four inner walls of the first mounting groove. The pressure plates and inclined plates are located around the tool to fix the tool around its perimeter, preventing the tool from shaking during operation and greatly ensuring the safety and stability of the tool during operation.

[0010] Preferably, a first strip-shaped hole is formed on the side wall of the first mounting groove, and the first strip-shaped hole slides with the upright plate. A second strip-shaped hole is formed on the side wall of the third mounting groove, and the second strip-shaped hole cooperates with the drive mechanism. The arrangement of the first strip-shaped hole and the second strip-shaped hole facilitates the drive mechanism to drive the lower pressure plate and the inclined plate to move, ensuring that the lower pressure plate and the inclined plate arranged around the perimeter cooperate with each other to fix the tool in the first mounting groove.

[0011] Preferably, the driving mechanism includes a partition plate, a worm gear, a worm, a threaded rod, and a movable plate. The movable plate is slidably installed in a third mounting groove. A fixed block is installed on the movable plate, and the fixed block is slidably engaged with a second slotted hole. The ends of the pulling rod are rotatably installed on the fixed block and the vertical plate, respectively. The partition plate is fixedly installed in the third mounting groove. One end of the threaded rod is rotatably installed on the inner wall of the third mounting groove, and a fixed shaft is fixedly installed on the other end of the threaded rod. The fixed shaft is rotatably installed on the partition plate. The movable plate is threadedly connected to the threaded rod. The worm gear is fixedly installed on the fixed shaft, and the worm is disposed on one side of the worm gear. The worm gear meshes with a countersunk groove on the mounting rod, and an internal hexagon nut is fixedly installed at the end of the worm. The internal hexagon nut is set in the countersunk groove. By rotating the internal hexagon nut, the worm gear is rotated, which in turn rotates the worm wheel. The worm wheel rotates, which in turn rotates the fixed shaft. The fixed shaft rotates, which in turn rotates the threaded rod. The threaded rod rotates, which in turn moves the moving plate along the third mounting groove. The movement of the moving plate moves the pulling rod, which in turn moves the lower pressure plate. Under the action of the inclined plate, the lower pressure plate can be moved towards the center of the first mounting groove while moving, which greatly ensures the device's efficiency and quality in fixing the tool.

[0012] Preferably, the unloading component includes a pallet, a lifting block, a fixed rod, a first spring, a guide rod, a slider, and rollers. The fixed rods are symmetrically arranged on both sides of the center line of the second mounting groove and are fixedly installed on the inner wall of the first mounting groove. A third slotted hole is opened on both sides of the center line of the fixed rod. The guide rod is fixedly installed in the slotted hole. The sliders are symmetrically arranged at both ends of the roller, and the sliders installed at both ends of the roller are slidably disposed in the third slotted holes on the fixed rods symmetrically arranged on both sides of the center line of the second mounting groove. The sliders are slidably connected to the guide rods. The first spring is disposed in the third slotted hole and sleeved on the guide rod. The rollers are symmetrically arranged on the fixed rods. On both sides of the center line, the support plate is set in the first mounting groove. A through hole is opened on the partition plate between the first mounting groove and the second mounting groove. The lifting block is fixedly installed between the support plate and the roller. The two side walls of the lifting block cooperate with the rollers symmetrically arranged on both sides of the center line of the fixed rod. The lifting block slides with the through hole. The end of the cutter pushes the support plate to one side of the fixed rod. The movement of the support plate drives the lifting block to move along the through hole. The lifting block will cooperate with the rollers arranged on both sides of the center line of the fixed rod. As the lifting block moves, it will push the rollers to both sides. The rollers will drive the slider to move to both sides along the guide rod. The movement of the slider will compress the first spring. The first spring always provides power for the lifting block to reset.

[0013] Preferably, the lifting block is configured with an isosceles trapezoid or isosceles triangle structure with notches at the four corners of the lifting plate. The notches slide in conjunction with the connection between the first and second sliding grooves. The lifting block facilitates the movement of the rollers located on both sides of the center line of the fixed rod, preventing uneven force from causing the support plate to tilt and greatly ensuring the normal operation of the unloading parts.

[0014] Preferably, it also includes a clamping mechanism and a pressure mechanism. The clamping mechanism includes a rotating plate, rotating arms fixedly installed at both ends of the rotating plate, and a protrusion installed at the bottom of the rotating arms. The connection between the rotating arms and the protrusion is rotatably mounted on the lower pressure plate. The protrusion cooperates with the side wall of the tool. The clamping mechanism cooperates with the rotating plate, and the rotating plate cooperates with the edge of the mounting rod. The clamping mechanism can fix the tool again after the clamping mechanism has fixed the tool, which greatly ensures the safety and stability of the tool during operation and ensures the normal operation of the tool.

[0015] Preferably, the pressure mechanism includes a vertical plate, a sliding rod, a push rod, and a second spring. The vertical plate is fixedly installed at the end of the lower pressure plate, the sliding rod is slidably installed on the vertical plate, the push rod is fixedly installed at one end of the sliding rod, and a sealing block is fixedly installed at the other end of the sliding rod. The second spring is sleeved on the sliding rod and is located between the push rod and the vertical plate. The pressure mechanism can reset the rotating plate, rotating arm, and protrusion, ensuring that the device can be used continuously and greatly improving the installation efficiency and quality of the tool.

[0016] The beneficial effects of this invention are:

[0017] 1) This device can fix the tool from multiple directions, ensuring that the tool is always in a stable state during the operation of the CNC machine tool. The drive mechanism, pull rod, lower pressure plate and tilt plate, together with the side wall of the first mounting groove, can fix the tool and prevent the tool from shaking or shifting during operation, which greatly ensures the safety and stability of the tool during operation.

[0018] 2) The vertical plate and the waist-shaped hole of this device can ensure that the lower pressure plate can squeeze the tool while moving, thereby achieving the purpose of fixing the tool and greatly ensuring the safety and stability of the tool during operation.

[0019] 3) The first and second slide grooves of this device can guide the inclined plate and the lower pressure plate, prevent the lower pressure plate and the inclined plate from shaking during operation, and ensure that the lower pressure plate and the inclined plate cooperate to fix the tool in the first mounting groove.

[0020] 4) The pressure plate and tilting plate of this device are set around the tool to fix the tool around the tool and prevent the tool from shaking during operation, which greatly ensures the safety and stability of the tool during operation.

[0022] 6) This device rotates the worm gear by rotating the internal hexagonal nut. The rotation of the worm gear drives the rotation of the worm wheel, which in turn drives the rotation of the fixed shaft. The rotation of the fixed shaft drives the rotation of the threaded rod, which in turn drives the moving plate to move along the third mounting slot. The movement of the moving plate drives the pulling rod to move, which in turn drives the lower pressure plate to move. Under the action of the inclined plate, the lower pressure plate can be moved towards the center of the first mounting slot while moving, which greatly ensures the device's efficiency and quality in fixing the tool.

[0023] 7) The end of the cutter in this device pushes the support plate to one side of the fixed rod. The movement of the support plate causes the lifting block to move along the through hole. The lifting block will cooperate with the rollers set on both sides of the center line of the fixed rod. As the lifting block moves, it will push the rollers to both sides. The rollers will drive the slider to move to both sides along the guide rod. The movement of the slider will compress the first spring. The first spring always provides power for the lifting block to reset.

[0024] 8) The lifting block of this device is designed to drive the rollers on both sides of the center line of the fixed rod to move to both sides, preventing uneven force from causing the pallet to tilt and greatly ensuring the normal operation of the unloading parts.

[0025] 9) The clamping mechanism of this device can fix the tool again after the clamping mechanism has fixed the tool, which greatly ensures the safety and stability of the tool during the working process and ensures the normal operation of the tool.

[0026] 10) The pressure mechanism of this device can reset the rotating plate, rotating arm and protrusion, ensuring that the device can be used continuously and greatly improving the installation efficiency and quality of the tool. Attached Figure Description

The setting of the second mounting groove 107, in conjunction with the first mounting groove 106, can install the feeder 5 and ensure the safety of the feeder 5.

[0049] like Figure 6As shown, the clamping member 2 includes a driving mechanism 201, a pulling rod 207, a lower pressure plate 203, and an inclined plate 204. The driving mechanism 201 is installed in the third mounting groove 108. The two ends of the pulling rod 207 are rotatably connected to the driving mechanism 201 and the lower pressure plate 203, respectively. The inclined plate 204 is fixedly installed on the top of the lower pressure plate 203, and the inclined plate 204 is inclined upward along the direction away from the first mounting groove 106. The lower pressure plate 203 cooperates with the side of the tool 6.

[0050] As an optimized solution of the present invention, such as Figure 6 As shown, a vertical plate 205 is also installed on the top of the lower pressure plate 203. A waist-shaped hole 206 is opened on the vertical plate 205. A fixing post 202 is fixedly installed on one end of the pull rod 207. The fixing post 202 is slidably arranged in the waist-shaped hole 206.

[0051] The vertical plate 205 and the waist-shaped hole 206 ensure that the lower pressure plate 203 can squeeze the tool 6 while moving, thereby fixing the tool 6 and greatly ensuring the safety and stability of the tool 6 during operation.

[0052] As an optimized solution of the present invention, such as Figure 4 As shown, a first sliding groove 105 and a second sliding groove 104 are provided on the side wall of the first mounting groove 106. The first sliding groove 105 and the second sliding groove 104 are arranged in a stepped manner, and the first sliding groove 105 is slidably engaged with the inclined plate 204, and the second sliding groove 104 is slidably engaged with the lower pressure plate 203.

[0053] The first slide 105 and the second slide 104 are designed to guide the inclined plate 204 and the lower pressure plate 203, prevent the lower pressure plate 203 and the inclined plate 204 from shaking during operation, and ensure that the lower pressure plate 203 and the inclined plate 204 cooperate to fix the tool 6 in the first mounting groove 106.

[0054] As an optimized solution of the present invention, such as Figure 2 , Figure 3 As shown, there are four of each of the pull rod 207, the lower pressure plate 203, and the inclined plate 204. The four pull rods 207, the lower pressure plate 203, and the inclined plate 204 are respectively located on the four inner walls of the first mounting groove 106.

[0055] The pressure plate 203 and the inclined plate 204 are arranged around the tool 6 to fix the tool 6 around its perimeter, preventing the tool 6 from shaking during operation and greatly ensuring the safety and stability of the tool 6 during operation.

[0056] As an optimized solution of the present invention, such as Figure 4As shown, a first strip hole 101 is formed on the side wall of the first mounting groove 106, and the first strip hole 101 is slidably engaged with the upright plate 205. A second strip hole 102 is formed on the side wall of the third mounting groove 108, and the second strip hole 102 is engaged with the drive mechanism 201.

[0057] The first strip hole 101 and the second strip hole 102 facilitate the driving mechanism 201 to move the lower pressure plate 203 and the inclined plate 204, ensuring that the lower pressure plate 203 and the inclined plate 204 arranged around the perimeter cooperate with each other to fix the tool 6 in the first mounting groove 106.

[0058] As an optimized solution of the present invention, such as Figure 6 , Figure 7 As shown, the drive mechanism 201 includes a partition plate 208, a worm gear 2014, a worm 2010, a threaded rod, and a movable plate 2012. The movable plate 2012 is slidably installed in the third mounting groove 108. A fixing block 2013 is installed on the movable plate 2012, and the fixing block 2013 is slidably engaged with the second slot 102. The ends of the pulling rod 207 are rotatably installed on the fixing block 2013 and the upright plate 205, respectively. The partition plate 208 is fixedly installed in the third mounting groove 108, and one end of the threaded rod is rotatably installed in the third mounting groove. On the inner wall of 108, a fixed shaft 209 is fixedly installed on the other end of the threaded rod. The fixed shaft 209 is rotatably installed on the partition plate 208. The movable plate 2012 is threadedly connected to the threaded rod. The worm gear 2014 is fixedly installed on the fixed shaft 209. The worm 2010 is located on one side of the worm gear 2014 and meshes with the worm gear 2014. A countersunk groove 103 is opened on the mounting rod 1. An internal hexagonal nut 2011 is fixedly installed at the end of the worm 2010. The internal hexagonal nut 2011 is located in the countersunk groove 103.

[0059] Rotating the internal hex nut 2011 drives the worm gear 2010 to rotate, which in turn drives the worm wheel 2014 to rotate. The worm wheel 2014 then drives the fixed shaft 209 to rotate, which in turn drives the threaded rod to rotate. The threaded rod then drives the moving plate 2012 to move along the third mounting groove 108. The movement of the moving plate 2012 then drives the pulling rod 207 to move, which in turn drives the lower pressure plate 203 to move. Under the action of the inclined plate 204, the lower pressure plate 203 can be moved towards the center of the first mounting groove 106 while moving, which greatly ensures the device's fixing efficiency and fixing quality for the tool 6.

[0060] As an optimized solution of the present invention, such as Figure 10As shown, the unloading component 5 includes a support plate 501, a lifting block 508, a fixing rod 504, a first spring 507, a guide rod 506, a slider 505, and a roller 503. The fixing rod 504 is symmetrically arranged on both sides of the center line of the second mounting groove 107, and the fixing rod 504 is fixedly installed on the inner wall of the first mounting groove 106.

The slider 505 is symmetrically arranged at both ends of the roller 503, and the sliders 505 installed at both ends of the roller 503 are respectively slidably arranged on the fixing rods 504 symmetrically arranged on both sides of the center line of the second mounting groove 107. In the third slot 502, the slider 505 is slidably connected to the guide rod 506. The first spring 507 is disposed in the third slot 502 and sleeved on the guide rod 506. The rollers 503 are symmetrically disposed on both sides of the center line of the fixed rod 504. The support plate 501 is disposed in the first mounting groove 106. A through hole 109 is opened on the dividing plate between the first mounting groove 106 and the second mounting groove 107. The lifting block 508 is fixedly installed between the support plate 501 and the rollers 503. The two side walls of the lifting block 508 cooperate with the rollers 503 symmetrically disposed on both sides of the center line of the fixed rod 504. The lifting block 508 is slidably engaged with the through hole 109.

[0061] The end of the cutter 6 pushes the support plate 501 to one side of the fixed rod 504. The movement of the support plate 501 causes the lifting block 508 to move along the through hole 109. The lifting block 508 will cooperate with the rollers 503 set on both sides of the center line of the fixed rod 504. As the lifting block 508 moves, it will push the rollers 503 to both sides. The rollers 503 will drive the slider 505 to move to both sides along the guide rod 506. The movement of the slider 505 will compress the first spring 507. The first spring 507 always provides power for the lifting block 508 to reset.

[0062] As an optimized solution of the present invention, such as Figure 10 As shown, the lifting block 508 is configured with an isosceles trapezoid or isosceles triangle structure in terms of side cross section, and notches 509 are opened at the four corners of the lifting plate. The notches 509 are slidably engaged with the connection between the first slide groove 105 and the second slide groove 104.

[0063] The lifting block 508 is designed to facilitate the movement of the rollers 503 located on both sides of the center line of the fixed rod 504, preventing uneven force from causing the pallet 501 to tilt and greatly ensuring the normal operation of the unloading part 5.

[0064] As an optimized solution of the present invention, such as Figure 1 , Figure 2 , Figure 3 As shown, it also includes a clamping mechanism 4 and a pressure mechanism 3, such as Figure 8 As shown, the clamping mechanism 4 includes a rotating plate 401, rotating arms 402 fixedly installed at both ends of the rotating plate 401, and a protrusion 403 installed at the bottom of the rotating arms 402. The connection between the rotating arms 402 and the protrusion 403 is rotatably installed on the lower pressure plate 203. The protrusion 403 cooperates with the side wall of the cutter 6. The clamping mechanism 4 cooperates with the rotating plate 401. The rotating plate 401 cooperates with the corner of the mounting rod 1.

[0065] The clamping mechanism 4 can fix the tool 6 again after the clamping mechanism has fixed the tool 6, which greatly ensures the safety and stability of the tool 6 during the working process and ensures the normal operation of the tool 6.

[0066] As an optimized solution of the present invention, such as Figure 9 As shown, the pressure mechanism 3 includes a vertical plate 301, a sliding rod 303, a push rod 304, and a second spring 305. The vertical plate 301 is fixedly installed at the end of the lower pressure plate 203. The sliding rod 303 is slidably installed on the vertical plate 301. The push rod 304 is fixedly installed at one end of the sliding rod 303. A blocking block 302 is fixedly installed on the other end of the sliding rod 303. The blocking block 302 can prevent the sliding rod 303 from sliding beyond its original range and affecting the normal operation of the pressure mechanism 3. The second spring 305 is sleeved on the sliding rod 303 and is located between the push rod 304 and the vertical plate 301.

[0067] The pressure mechanism 3 is designed to reset the rotating plate 401, rotating arm 402 and protrusion 403, ensuring that the device can be used continuously and greatly improving the installation efficiency and quality of the tool 6.

[0068] like Figure 11 As shown, its working process is as follows:

[0069] Insert the end of the cutter 6 into the first mounting groove 106 on the mounting slot, and simultaneously push the cutter 6 to compress the support plate 501. The operator rotates the hexagonal nut 2011 with a wrench or electric wrench. The hexagonal nut 2011 drives the worm gear 2010 to rotate. The rotation of the worm gear 2010 drives the worm wheel 2014 to rotate. The rotation of the worm wheel 2014 drives the fixed shaft 209 to rotate. The rotation of the fixed shaft 209 drives the threaded rod to rotate. The rotation of the threaded rod drives the moving plate 2012 to move along the third mounting groove 108. The movement of the moving plate 2012 will drive the pulling rod 207 to move. The movement of the pulling rod 207 will drive the lower pressure plate 203 to move. Under the action of the inclined plate 204, the lower pressure plate 203 can be moved towards the center of the first mounting groove 106 while moving, thereby fixing the cutter 6 in the first mounting groove 106 on the mounting rod 1.

[0070] As the lower pressure plate 203 moves, it drives the rotating arm 402, the rotating plate 401, and the protrusion 403 to move toward the inside of the first mounting groove 106. As the rotating plate 401, the rotating arm 402, and the protrusion 403 move, they will cooperate with the end of the mounting groove. As the rotating arm 402 moves, it will rotate. The rotation of the rotating arm 402 will drive the protrusion 403 to rotate. The rotation of the protrusion 403 will cause the protruding part of the protrusion 403 to press on the tool 6, thereby achieving the purpose of pressing the tool 6 tightly, which greatly ensures the stability and safety of the tool 6 during the working process.

[0071] When it is necessary to remove the tool 6, simply rotate the internal hex nut 2011 in the opposite direction. At the same time, under the action of the sliding rod 303, the second spring 305 and the push rod 304, the rotating arm 402 and the rotating plate 401 can be rotated in the opposite direction, thereby releasing the restriction of the end protrusion 403 of the rotating arm 402 on the tool 6, and greatly improving the efficiency of tool 6 installation and removal.

[0072] The above description is merely an example and illustration of the structure of the present invention. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the scope defined by the structure of the present invention, they should all fall within the protection scope of the present invention.
