Description

Technical Field

[0001] The invention relates to the technical field of machine tools, and in particular to a chip removal device and method for processing waste chips of machine tools. Background Art

[0002] Machine tools are basic equipment for manufacturing various machines and mechanical parts. Through cutting, grinding, drilling and other processes, raw materials are processed into parts that meet the requirements. At the same time, machine tools will generate a large amount of chips during the processing. If they are not removed in time, they may block the working space, affect the processing quality and the normal operation of the machine tool, and even cause the automatic line to be unable to work continuously. The accumulation of chips may also aggravate the wear of machine tool parts, pollute the cutting fluid, and reduce the surface quality of the processed parts; At present, the discharge of machine tool processing waste chips is mainly through manual cleaning or the use of chip removal devices, such as spiral chip conveyors, scraper chip conveyors, chain chip conveyors, magnetic chip conveyors, etc., so as to quickly discharge the processing waste chips and ensure the normal operation of the machine tool.

[0003] A chip crushing mechanism and a CNC machine tool disclosed in the patent application with reference publication number CN112496847A. The spiral chip conveyor formed by the chip groove and the chip conveying screw of the CNC machine tool can directly solve the collection and automatic processing of filamentary metal waste chips. Installing it on the CNC machine tool can effectively enhance the popularization and promotion of automation in the machine tool industry.

[0004] At present, most CNC machine tools use a combination of discharge ports and conveying equipment to complete the active conveying and discharge of waste chips. For example, the above-mentioned CNC machine tools complete the active conveying and discharge of waste chips through chip grooves and chip screws. However, when the chip groove method is actually used on CNC machine tools, due to the different space of CNC machine tools, it is necessary to add extended guide tables on both sides of the chip groove so that the waste chips can be guided into the chip groove. At the same time, during machining, the waste chips fly everywhere, so a large amount of waste chips will accumulate on the extended guide table, affecting the flow of waste chips. At the same time, the accumulated waste chips will affect the chip removal performance of the machine tool, increase the difficulty of subsequent cleaning, increase the failure rate, and cause problems such as rust on the machine tool.

The CNC milling cutter is assembled on the cutter shaft 103 to complete cutting processing on the workpiece on the fixture 102, and also includes: The chip removal groove 2 is arranged below the processing area of ​​the machine tool body 1 for collecting waste chips. The chip removal groove 2 is in an inverted trapezoidal structure as a whole, which is conducive to the centralized collection of waste chips. Inclined platforms 3 for guiding materials are arranged on both sides of the top of the chip removal groove 2. The inclined platforms 3 guide the processing waste chips into the chip removal groove 2 to avoid accumulation. A chip removal screw 4 for conveying waste chips is rotatably installed in the chip removal groove 2; The power unit is arranged on one side of the machine tool body 1 to provide power to the chip removal screw 4. An assembly area 10 is installed on one side of the frame 101. The power unit is correspondingly installed in the assembly area 10 to be hidden, and a sealing cover for sealing the assembly area 10 is detachably installed on the frame 101; like Figure 5 As shown, two synchronous cleaning units, the number of which can be freely increased or decreased according to the design requirements of the chip groove 2 in the machine tool body 1, to ensure that the waste chips enter the chip groove 2 smoothly and avoid accumulation. The units are arranged on two tilting tables 3 in the machine tool body 1, and the waste chips on the tilting table 3 are actively pushed back and forth in a variety of cleaning methods through the synchronous cleaning units. Both of the two synchronous units are power-connected with the power unit, and each synchronous cleaning unit is divided into a driving part, a cleaning part and an auxiliary part. The driving part is used to receive the power of the power unit and complete the transmission, and the cleaning part is controlled by the driving part to perform reciprocating dislocation cleaning work on the tilting table 3. The auxiliary part is used to assist the cleaning work of the cleaning part. A protective mechanism for isolation is provided on the driving part and the auxiliary part.

[0026] like Figure 6 As shown, the power unit includes: A drive shaft 6 is rotatably arranged in the machine tool body 1 and is transmission-connected to the chip removal screw 4. A drive motor 7 transmission-connected to the drive shaft 6 is installed in the assembly area 10 of the machine tool body 1 through a bracket, and two No. 1 synchronous wheels 8 are sleeved at corresponding intervals on the outside of the drive shaft 6. The No. 1 synchronous wheel 8 is detachably connected to the drive shaft 6; It is worth noting that when the waste chips are discharged: a power unit is provided to mount the workpiece on the fixture 102, and then the walking system and the tool shaft 103 are controlled to work, thereby completing the machining operation of the workpiece on the fixture 102, and the waste chips generated during machining fall into the chip discharge groove 2, and at the same time, the waste chips are guided and transported through the tilting table 3, which is conducive to the transfer of the waste chips to the chip discharge groove 2 waiting for transportation, and then the drive motor 7 is started to drive the drive shaft 6 and the chip discharge screw 4 to rotate. The rotating chip discharge screw 4 can quickly discharge the machining waste, and finally send it out through the lower hopper 5 for subsequent recycling, which reduces the difficulty of chip removal and can complete the discharge of a large amount of waste chips generated during machining.

[0027] Embodiment 3: Based on the synchronous cleaning unit provided in Embodiment 1, this embodiment provides a further technical solution of the synchronous cleaning unit.

[0028] like Figure 7 and Figure 8 As shown, the driving member includes: A synchronous shaft 9 is rotatably mounted on one side of the machine tool body 1, and one side of the synchronous shaft 9 corresponds to extending into the assembly area 10. A second synchronous wheel 11 is detachably fixedly mounted on one end of the synchronous shaft 9 extending to the assembly area 10. A synchronous belt 12 for transmission is installed between the first synchronous wheel 8 and the second synchronous wheel 11. The power of the drive shaft 6 is transmitted to the synchronous shafts 9 of the two synchronous cleaning units through the synchronous belt 12. Two reciprocating parts are symmetrically arranged on both sides of the machine tool body 1, each reciprocating part includes a reciprocating frame 13, a reciprocating screw 14 and a screw nut 15. The reciprocating frame 13 is detachably fixedly connected to the machine tool body 1 through a bracket, the reciprocating screw 14 is correspondingly rotatably installed in the reciprocating frame 13, the screw nut 15 is slidably installed and engaged in the reciprocating frame 13, and the screw nut 15 is correspondingly sleeved on the outside of the reciprocating screw 14. The reciprocating frame 13 and the tilting table 3 are installed in the same tilting manner, and the screw nut 15 is controlled by the reciprocating screw 14 to reciprocate in the reciprocating frame 13; Two power boxes are symmetrically arranged on both sides of the outside of the synchronous shaft 9, each power box includes a box body 16, a first bevel gear 17 and a second bevel gear 18, the first bevel gear 17 and the second bevel gear 18 are meshed and rotatably installed in the box body 16, the box body 16 is correspondingly sleeved on the outside of the synchronous shaft 9, and the box body 16 is detachably fixedly connected to the front end of the reciprocating frame 13, the first bevel gear 17 is fixedly sleeved on the outside of the synchronous shaft 9, and the second bevel gear 18 is transmission-connected to the reciprocating screw 14, and the power is transmitted to the reciprocating screw 14 through the meshing of the first bevel gear 17 and the second bevel gear 18; like Fig. 9 and Fig.10 As shown, the driving member also includes: Two guide plates 19 are correspondingly arranged below one side of the two reciprocating frames 13. Specifically, the guide plates 19 are detachably fixedly connected to the machine tool body 1 through a bracket. A first inclined surface 20 is arranged on one side of each guide plate 19, and a second inclined surface 21 is arranged on the other side of each guide plate 19. The inclination directions of the first inclined surface 20 and the second inclined surface 21 are consistent. The position switching adjustment of the cleaning piece is completed by the cooperation of the first inclined surface 20, the second inclined surface 21 and the guide plate 19; Two sensing arms are correspondingly arranged between the guide plate 19 and the screw nut 15 to complete the control of the cleaning piece. Each sensing arm includes a lifting frame 22 and a lifting block 23. The lifting frame 22 can be detachably fixed on the screw nut 15. The lifting block 23 is slidably engaged in the lifting frame 22. A pulling spring 24 is installed between the lifting frame 22 and the lifting block 23. The elastic strength of the pulling spring 24 is set to pull the cleaning piece to move to the area between the No. 1 inclined surface 20 and the top of the guide plate 19. The subsequent cleaning piece is reset to the No. 2 inclined surface 21 below the top of the guide plate 19 by gravity, so that the cleaning piece can move smoothly under the guidance of the guide plate 19. A connecting seat 25 connected to the cleaning piece is installed on one side of the lifting block 23; Two sensing wheels 26 are rotatably mounted on one side of the two screw nuts 15, and each sensing wheel 26 is in contact with the side wall of the guide plate 19. The position control of the cleaning piece is completed through the contact between the sensing wheel 26 and the first inclined surface 20 and the second inclined surface 21; It is worth noting that when assisting the discharge of waste chips: during machining, a large amount of waste chips will accumulate on the tilting table 3, thereby reducing the fluidity of the waste chips and making it impossible to complete the rapid material discharge work, which has a great impact on the discharge of the waste chips. Therefore, a synchronous cleaning unit is provided, and the power of the rotating shaft is transmitted to the synchronous shaft 9 through the synchronous belt 12. The synchronous shaft 9 drives the first bevel gear 17 to rotate, and transmits the power to the reciprocating screw 14 through the second bevel gear 18, so that the screw nut 15 can complete the reciprocating movement under the restriction of the reciprocating frame 13, and can synchronously link the cleaning piece to complete the reciprocating material pushing action, thereby improving the cleaning efficiency; In order to avoid the problem that the cleaning piece is easy to push the waste chips in the reverse direction during the reset movement, a guide plate 19 is added. Therefore, when the screw nut 15 reciprocates, it contacts the guide plate 19 via the sensing wheel 26. When the sensing wheel 26 is guided to the bottom of the guide plate 19 via the second inclined surface 21, the cleaning piece contacts the tilting table 3 to complete the pushing work. When the sensing wheel 26 is guided to the top of the guide plate 19 via the first inclined surface 20, the cleaning piece moves up as a whole and separates from the tilting table 3, thereby completing the avoidance and avoiding the problem of reverse pushing. Specifically, when the screw nut 15 moves forward, the sensing wheel 26 contacts the lower surface of the guide plate 19. At this time, the lifting block 23 is located at the bottom of the lifting frame 22. The cleaning piece contacts the surface of the tilting table 3 to complete the pushing. When the screw nut 15 moves forward to the limit position, the sensing wheel 26 is The pulling spring 24 pulls, causing the cleaning piece to move up a distance as a whole, and then the lead screw nut 15 moves back and resets, so that the sensing wheel 26 contacts the No. 1 inclined surface 20, and then under the continuous pulling of the lead screw nut 15, the sensing wheel 26, the lifting block 23 and the cleaning piece are guided through the No. 1 inclined surface 20, so that the sensing wheel 26 moves to the top of the guide plate 19 to complete the dislocation avoidance, and then the lead screw nut 15 moves back to the limit position, and the pulling spring 24 is stretched by the gravity of the cleaning piece. At the same time, under the guidance of the No. 2 inclined surface 21, the cleaning piece quickly transitions to the bottom of the guide plate 19 to complete the pushing. Through the cooperation of the guide plate 19, the No. 1 inclined surface 20 and the No. 2 inclined surface 21, the pushing of the cleaning piece and the active dislocation avoidance control can be completed, thereby ensuring the cleaning accuracy.

When the sensing wheel 26 contacts the lower surface of the guide plate 19, the magnetic column 40 and the magnetic plate 43 are close to each other. It is worth noting that: when auxiliary cleaning is performed: by providing auxiliary parts, the No. 1 pipe 38 is connected to the cutting fluid pipeline of the machine tool body 1, or connected to the external cleaning fluid source, and the No. 2 pipe 39 is connected to the delivery pipe 32. Then, when the cleaning scraper contacts the tilting table 3, the magnetic column 40 hidden on the sensing wheel 26 and the magnetic plate 43 set at the bottom of the guide plate 19 are close to each other. Driven by magnetism, the magnetic column 40 overcomes the elastic linkage of the opening and closing spring 42 and the movable block 371 moves in the control chamber 36, so that the movable block 371 and the fixed block 372 are misaligned to open the No. 1 pipe 38, and the cutting fluid enters the control chamber 36 through the No. 1 pipe 38, and then is sent into the control chamber 36 through the No. 2 pipe 39. In the conveying pipe 32, the surface of the tilting table 3 is finally flushed and cleaned through multiple branch pipes 33 and cleaning nozzles 34, which improves the cleaning effect of the cleaning piece and can complete multiple cleaning operations. It can actively clean different types of waste chips. When the cleaning piece is separated from the tilting table 3, the magnetic column 40 and the magnetic plate 43 are also misaligned and separated. The opening and closing spring 42 pulls the magnetic column 40 and the movable block 371 to reset, closes the control chamber 36 again, and stops providing cleaning fluid, thereby completing intermittent delivery and avoiding the waste of cleaning fluid after the cleaning piece is separated from the tilting table 3. It can complete follow-up cooperation with the cleaning piece, reduces the control difficulty, and can complete free follow-up opening and closing.
