Description

A CNC machining tool Technical Field

[0001] This application relates to the technical field of machine tools, and in particular to a CNC machining tool. Background Technology

[0002] A CNC machine tool is an automated machine tool equipped with a program control system. It can automatically process parts according to pre-set requirements. During the processing, some debris is inevitably generated. The debris is scattered randomly on the machine bed. A large accumulation of debris will aggravate the wear of moving components and processing components, affecting the service life of the CNC machine tool.

[0003] Therefore, regular cleaning by staff is required, but the scattered debris makes the cleaning work quite tedious. Summary of the Invention

[0004] In order to collect the debris produced during processing, this application provides a CNC machining tool.

[0005] The CNC machining tool provided in this application adopts the following technical solution: A CNC machining tool includes a frame, a clamping mechanism, a machining mechanism, a sliding seat, and a receiving hopper. The clamping mechanism is connected to the frame and is used to clamp workpieces. The sliding seat is slidably connected to the frame, and the sliding direction of the sliding seat is horizontal. The machining mechanism is connected to the sliding seat and is used to process the workpieces clamped in the clamping mechanism. The receiving hopper is connected to the side of the sliding seat near the clamping mechanism and is located below the machining mechanism. The upper surface of the receiving hopper is provided with a receiving groove.

[0006] By adopting the above technical solution, a receiving hopper is set up to collect the debris produced during the processing of the workpiece, preventing the debris from falling randomly onto the machine frame, reducing the wear and tear on the moving and processing components caused by the debris, extending the service life of the CNC machine tool, and simplifying the cleaning work.

[0007] Preferably, it also includes a cooling mechanism, which includes a liquid storage tank and a nozzle. The liquid storage tank is connected to the frame and has a liquid storage chamber for storing coolant. The nozzle is connected to the frame and its lower end faces the workpiece to be processed. The nozzle is connected to the liquid storage chamber through a pipe and a delivery pump.

[0008] By adopting the above technical solution, the machine frame is equipped with a reservoir for storing coolant. The coolant is delivered to the nozzles facing the workpiece through pipes and a delivery pump. This can cool the workpiece and the cutting tool during the processing, reduce the temperature, reduce tool wear, improve processing accuracy and quality, and the coolant helps the debris fall into the receiving trough.

[0009] Preferably, it also includes a temporary storage component, which includes a temporary storage box and a cover plate. The temporary storage box is connected to one end of the receiving hopper along the sliding direction perpendicular to the sliding seat. The upper end of the temporary storage box is provided with a temporary storage cavity, which is connected to the receiving trough. The receiving trough is inclined towards the side closer to the temporary storage box. The bottom of the temporary storage cavity is provided with a discharge port, which passes through the temporary storage box. The cover plate is rotatably connected to the temporary storage box and covers the discharge port. When the sliding seat is located on the side of the frame away from the clamping mechanism, the temporary storage box is located above the liquid storage tank.

[0010] By adopting the above technical solution, when the processing mechanism is processing, the cover plate closes the discharge port, so that the debris and coolant in the receiving trough flow into the temporary storage chamber of the temporary storage box for temporary storage. When the sliding seat is located on the side of the frame away from the clamping mechanism, the temporary storage box is located above the liquid storage tank. The cover plate rotates, so that the discharge port is connected to the liquid storage chamber, which facilitates the transfer of debris in the temporary storage chamber to the liquid storage tank. This further realizes the collection of debris produced during processing, which is convenient for subsequent processing and reuse of the coolant, thereby improving the utilization rate of the coolant.

[0011] Preferably, the temporary storage component further includes a sleeve, which is slidably connected to the lower end of the temporary storage box. The sleeve slides vertically, and the inner side of the sleeve is connected to the discharge port. The lower end of the sleeve abuts against the surface of the cover plate near the discharge port.

[0012] By adopting the above technical solution, when the cover plate rotates away, the sleeve extends into the liquid storage chamber under the action of gravity, which facilitates the precise entry of coolant and debris in the temporary storage chamber into the liquid storage chamber, reduces the possibility of coolant and debris falling onto the outer wall of the liquid storage chamber, and ensures a clean working environment.

[0013] Preferably, it further includes a feeding assembly, which includes a pusher plate, a pusher motor, and a pusher screw. The pusher plate is slidably embedded in the receiving groove and is in contact with the bottom of the receiving groove. The pusher screw is rotatably connected to the receiving hopper, and the rotation axis of the pusher screw is parallel to the sliding direction of the pusher plate. The pusher motor is connected to the receiving hopper and is used to drive the pusher screw to rotate.

[0014] By adopting the above technical solution, the coolant and debris in the receiving tank are cleaned regularly, which helps to keep the receiving tank clean during the next processing of the workpiece, making it easier to accommodate more debris and coolant, and improving the reliability of the equipment.

[0015] Preferably, it further includes a locking member and a first reset member. The locking member is slidably connected to the receiving hopper, and the sliding direction of the locking member is perpendicular to the sliding direction of the push plate. The side wall of the cover plate is provided with a locking groove, and the locking member is used to be embedded in the locking groove. The other end of the locking member is used to extend into the receiving groove. The end of the locking member near the receiving hopper is provided with a first chamfer. The first chamfer is located on the side of the locking member away from the temporary storage cavity and is used to abut against the push plate. The first reset member is connected between the locking member and the receiving hopper. The first reset member makes the locking member tend to extend into the receiving groove. When the locking member extends into the receiving groove, the locking member is embedded in the locking groove.

[0016] By adopting the above technical solution, the first reset component allows the locking component to be embedded in the locking groove to achieve relative fixation between the cover plate and the temporary storage box, reducing the possibility of the cover plate opening when the temporary storage box is not above the liquid storage tank, and improving the reliability of the equipment. When the push plate slides to the side of the receiving groove close to the temporary storage box, the push plate pushes the locking component to slide, causing the locking component to disengage from the locking groove, thereby releasing the locking component from the cover plate. Under the action of gravity, the cover plate rotates away from the temporary storage box, allowing the coolant and debris in the temporary storage chamber to enter the liquid storage chamber through the discharge port.

[0017] Preferably, the locking element includes a connecting block, a shrinking block, and a second reset element. The rotation axis of the cover plate is located on the side of the temporary storage box near the clamping mechanism. The connecting block is slidably connected to the receiving hopper, and the shrinking block is slidably connected to the connecting block. The sliding direction of the shrinking block is horizontal. The shrinking block is used to abut against the surface of the cover plate away from the discharge port. The end of the shrinking block near the cover plate is provided with a second chamfer. The second chamfer is located on the side of the shrinking block away from the discharge port and is used to abut against the cover plate. The second reset element is connected between the shrinking block and the connecting block. The second reset element makes the shrinking block tend to embed into the locking groove.

[0018] By adopting the above technical solution, when the sliding seat slides close to the clamping mechanism, the cover plate abuts against the wall of the liquid storage cavity, causing the cover plate to rotate and fit against the lower end of the temporary storage box. The cover plate abuts against the second chamfer, pushing the shrink block to slide. When the shrink block is aligned with the locking groove, the second reset component drives the shrink block to embed into the locking groove to achieve a fixed connection between the cover plate and the temporary storage box, automatically closing the temporary storage cavity and improving the automation level of the equipment.

[0019] Preferably, the cooling mechanism further includes a filter frame, an installation groove is provided on the outer wall of the liquid storage tank, the installation groove is connected to the liquid storage cavity, the filter frame is embedded in the installation groove, the upper end of the filter frame is provided with a receiving groove, and a plurality of filter holes are evenly distributed at the bottom of the receiving groove.

[0020] By adopting the above technical solution, an installation groove is set up, and the filter frame is embedded in the installation groove to filter the coolant and debris entering the liquid storage chamber, reducing the possibility of debris entering below the filter frame and causing damage to the subsequent delivery pump, and improving the service life of the equipment.

[0021] Preferably, the cooling mechanism further includes a sealing assembly, which includes a rotating plate and a retaining strip. The rotating plate is rotatably embedded in the liquid storage chamber, and the rotation axis of the rotating plate is horizontal. The rotating plate is located above the filter holes. There are two rotating plates, which are symmetrically distributed along a line perpendicular to the rotation axis of the rotating plate. The number of retaining strips is the same as the number of rotating plates and corresponds one-to-one. The retaining strip is connected to the side of the rotating plate closest to the other rotating plate and is used to abut against the other retaining strip.

[0022] By adopting the above technical solution, the two rotating plates rotate, causing the two clamping strips to clamp together, thereby sealing the liquid storage chamber. This allows the coolant and debris entering the storage chamber to be temporarily stored above the rotating plates when the filter frame is replaced or cleaned, reducing the possibility of coolant and debris scattering to the outside of the storage tank through the mounting groove and improving the reliability of the equipment.

[0023] Preferably, the sealing assembly further includes gears, a rack, a pin, and a third reset member. The number of gears is the same as the number of rotating plates and corresponds one-to-one. The gears are connected to the rotating plates, and the gear axes coincide with the rotation axes of the rotating plates. The rack is slidably connected to the storage tank, and the sliding direction of the rack is vertical. The rack is located between two gears and meshes with them. The rack is used to abut against the end of the filter frame away from the bottom of the mounting groove. The third reset member is connected between the rack and the storage tank, and the third reset member makes the rack tend to abut against the filter frame. The rack has a connecting hole, and the pin is slidably embedded in the connecting hole on the same axis. The sliding direction of the pin is perpendicular to the sliding direction of the rack. The outer wall of the storage tank has a fixing hole for the pin to be inserted to achieve a fixed connection between the rack and the storage tank.

[0024] By adopting the above technical solution, the rack is slidably connected to the liquid storage tank and used to abut against the filter frame, reducing the possibility that the filter frame will detach from the liquid storage tank during use, thus causing the filter frame to lose its filtering effect on the coolant. When the filter frame needs to be replaced or cleaned, the rack is pushed to slide, thereby releasing the rack's limit on the filter frame. At the same time, the rack meshes with the gear, driving the gear to rotate, which in turn drives the rotating plate to rotate and close the liquid storage chamber. The locking pin is embedded in the fixing hole to position the rack, reducing the possibility of the rack sliding when replacing the filter frame and improving the reliability of the equipment.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. The receiving hopper is set up to collect the debris produced by the workpiece, preventing the debris from scattering randomly on the machine frame, reducing the wear caused by the debris on the moving components and processing components, extending the service life of the CNC machine tool, and simplifying the cleaning work; 2. Regularly cleaning the coolant and debris in the receiving trough helps to keep the receiving trough clean during the next workpiece processing, making it easier to accommodate more debris and coolant, and improving the reliability of the equipment; 3. When the sliding seat slides close to the clamping mechanism, the cover plate abuts against the wall of the liquid storage cavity, driving the cover plate to rotate and fit against the lower end of the temporary storage box. The cover plate abuts against the second chamfer, pushing the shrink block to slide. When the shrink block is aligned with the locking groove, the second reset component drives the shrink block to embed into the locking groove to achieve a fixed connection between the cover plate and the temporary storage box, automatically closing the temporary storage cavity and improving the automation level of the equipment.

The retaining strip 642 is fixedly connected to the side surface of the rotating plate 641 near the other rotating plate 641. The retaining strip 642 is used to abut against the other retaining strip 642. A rotating plate 641 is fixedly connected to a rotating shaft 6411, the axis of which coincides with the rotation axis of the rotating plate 641.

When the connecting hole 6441 is misaligned with the fixing hole 613, the side of the rotating plate 641 closer to the other rotating plate 641 is tilted towards the side closer to the filter hole.

[0042] The implementation principle of a CNC machining tool according to an embodiment of this application is as follows: the transverse drive assembly 42 and the longitudinal drive assembly 43 drive the sliding seat 41 to slide, thereby driving the machining mechanism 3 to process the workpiece held by the clamping mechanism 2. The nozzle 62 sprays coolant onto the workpiece and the machining mechanism 3. The coolant carries debris into the receiving groove 511 and slides along the bottom of the receiving groove 511 into the temporary storage cavity 5211.

[0043] The sliding seat 41 slides away from the three-jaw chuck 21, and the temporary storage box 521 is located above the liquid storage tank 61. The pusher motor 533 drives the pusher screw 532 to rotate. The pusher screw 532 drives the pusher plate 531 to slide, pushing the coolant and debris in the receiving groove 511 into the temporary storage chamber 5211. The pusher plate 531 abuts against the first chamfer 541111, pushing the first insert 54111 to slide, driving the second insert 54113 to slide, and driving the shrink block 5412 to disengage from the locking groove 5221. The cover plate 522 rotates under the action of gravity, so that the temporary storage chamber 5211 is connected to the liquid storage chamber 611 through the discharge port 5212. The coolant and debris in the temporary storage chamber 5211 fall into the receiving groove 631 through the discharge port 5212.
