Technical Field

[0001] The invention relates to the technical field of metal chip cleaning equipment, and in particular to a metal chip cleaning device for metal processing. Background Art

[0002] Metal processing is mainly divided into two types: changing the shape of the workpiece and changing the properties of the workpiece. Among the changes in the shape of metal blanks, mechanical processing is the most common metal processing method, which includes cutting, grinding and special processing. When machining metal workpieces, they are often shaped through four processes of turning, milling, planing and grinding to meet the standard size requirements of the parts.

[0003] At present, when machining metal workpieces, CNC machine tools are often used to process the machining surface. However, during the turning, milling and grinding process, the removed metal chips will remain on the workbench and mix with the cutting fluid, affecting the cleanliness of the workbench. When the workpiece is processed again, in order to avoid the scraps staying in the clamping part and causing scratches on the clamping surface of the workpiece, the surface of the workbench needs to be cleaned; Moreover, during the process of drilling holes in metal workpieces, metal scraps will adhere to the processing holes and cannot fall directly onto the workbench. The workpiece needs to be removed from the processing table before the metal scraps in the holes can be cleaned. This cleaning method will undoubtedly reduce the metal processing efficiency of the workpiece. Summary of the invention

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] Example, see Figures 1 to 10 A metal chip cleaning device for metal processing includes a workbench 1 for machining a metal workpiece. The workbench 1 changes the machining surface of the metal workpiece by means of a displacement control hydraulic cylinder 11. The workbench 1 clamps the metal workpiece by means of a workpiece clamping seat 12. A table cleaning mechanism is arranged outside the workbench 1 for cleaning the metal chips adhered to the table. A hole and groove cleaning mechanism is arranged above the table cleaning mechanism for cleaning the metal chips adhered to the machining hole of the metal workpiece. It should be noted that: in the present invention, the workbench 1 can drive the workbench 1 to translate through the displacement control hydraulic cylinder 11, so that it can cooperate with existing mechanical processing equipment such as CNC numerical control machine tool processing components to process metal workpieces. Here, the displacement control hydraulic cylinder 11 is an existing hydraulic control component such as a platform moving hydraulic control component of a CNC numerical control machine tool; Based on the above, before processing, the workpiece clamping seat 12 is installed on the slide groove on the workbench 1, and the metal workpiece can be locked on the top of the workbench 1 through the hexagon socket bolt. This is an existing metal workpiece clamping method and is a prior art. In the subsequent description, the control principle part of the displacement control hydraulic cylinder 11 and the clamping principle part of the workpiece clamping seat 12 will not be repeated. In the present invention, the metal chip cleaning process of the metal workpiece hole groove is based on the ability to remove the hole groove with the metal chip specification by wind force, and is not aimed at all the hole grooves generated during the processing of the metal workpiece.

[0023] like Figure 3 and Fig. 9 As shown, the worm gear drive assembly includes a stepper motor 4 arranged on the top of the waste cleaning net 21, and the output shaft of the stepper motor 4 is connected to a driving worm gear 42 through a driving worm 41, and the driving worm gear 42 is fixed to a side of the cleaning closing arm 3 close to the driving worm 41.

[0024] It should be noted that: Figure 3 and Figure 5As shown, a driving sealing shell 25 is fixed on the top of the cleaning table 2, and an arc-shaped movable hole is opened on the inner wall of the driving sealing shell 25. The cleaning sealing arm 3 closes the movable hole through the closed arc slide 32, and a rotating shaft rotatably connected to the driving sealing shell 25 is provided at the center of the driving worm gear 42 of the cleaning sealing arm 3, so that the cleaning sealing arm 3 can rotate stably; Furthermore, a closed space is formed by driving the closed shell 25 between the waste chip cleaning net 21 and the cleaning table 2, so that the driving environment of the driving cleaning closed arm 3 is not affected by metal chips and cutting fluid when the stepping motor 4 is started to drive the driving worm gear 42 to rotate; like Figures 2 to 5 As shown, the table cleaning mechanism includes a cleaning table 2 arranged below the workbench 1, a waste cleaning net 21 is arranged inside the cleaning table 2, a collecting port adapted to the cleaning closing arm 3 is opened on the top of the waste cleaning net 21, the collecting port is closed on the top of the cleaning table 2 by the cleaning closing arm 3, the inclination angle of the cleaning closing arm 3 is controlled by a worm and worm gear drive assembly, and a cleaning fan 31 is arranged inside the cleaning closing arm 3.

[0025] It should be noted that when the worm gear drive assembly controls the cleaning closing arm 3 to tilt toward the workbench 1, the cleaning closing arm 3 is disengaged from the locking state with the collecting port, so that when the cleaning fan 31 is turned on, the metal waste on the table surface can be driven downward along the collecting port to complete the cleaning operation of the workbench 1 surface.

[0026] Furthermore, a rotary concave surface is provided on the top of the waste chip cleaning net 21, a cutting fluid passage 211 is provided at the top center of the waste chip cleaning net 21, a rotary sleeve 22 located above the rotary concave surface is fixedly installed in the cleaning table 2, and the rotary sleeve 22 and the waste chip cleaning net 21 are both provided as a mesh structure; It should be noted that: a cutting fluid cleaning concentrator 23 connected to the cutting fluid through pipe 211 is fixed to the bottom of the cleaning table 2 by fixing bolts, a limiting groove is provided on the top of the cutting fluid cleaning concentrator 23, and the waste chip cleaning net 21 is clamped on the top of the cutting fluid cleaning concentrator 23 through the limiting groove; Furthermore, when the metal scraps fall through the collecting port, the metal scraps are blocked by the scrap cleaning net 21, and the airflow passing through the metal scraps is guided by the rotating sleeve 22, so that the atomized cutting fluid can enter the cutting fluid cleaning concentration pipe 23, and while completing the cleaning of the metal scraps, the cutting fluid therein is separated, thereby reducing the processing steps of the cutting fluid after cleaning, thereby achieving the effect of improving the cleaning efficiency.

[0027] Based on the above, the rotary sleeve 22 is composed of a lower ventilation sleeve 221 and an upper ventilation sleeve 222. The outer surface of the lower ventilation sleeve 221 is rotatably connected with a cleaning and stacking sleeve 24, and a blocking net 223 is provided on the top of the upper ventilation sleeve 222 to block the metal scraps entering the lower ventilation sleeve 221. It should be noted that: the outer surface of the cleaning and stacking sleeve 24 is fixed with inclined fan blades 241, and the bottom of the cleaning and stacking sleeve 24 is provided with stacking vortex bars 242. When there is less metal waste, the airflow generated by the cleaning fan 31 can provide driving force for the inclined fan blades 241, drive the stacking vortex bars 242 to rotate, and concentrate a small amount of metal waste to the outer wall of the upper ventilation sleeve 222, avoiding the small amount of waste directly adhering to the air inlet at the bottom of the lower ventilation sleeve 221, blocking subsequent metal waste, reducing the amount of metal waste collected, and achieving the effect of improving the metal waste blocking rate of the waste cleaning net 21.

[0028] A further benefit of adopting the above method is that when the metal scraps are accumulated to a certain amount on the outer wall of the upper ventilation sleeve 222 through the accumulation vortex bars 242, and the amount of scraps collected between the lower ventilation sleeve 221 and the upper ventilation sleeve 222 is saturated, the metal scraps will act as a filter filler for capturing the atomized cutting fluid, and the rotating sleeve 22, which is arranged to rotate, can increase the flow path of the cleaning airflow, thereby cooperating with the blocked metal scraps to increase the ability to capture the atomized cutting fluid, thereby accelerating the dissipation rate of the atomized cutting fluid in the metal workpiece processing area, so that subsequent workers can place the next workpiece in an environment where there is no atomized cutting fluid blocking their sight.

[0029] like Figure 6 , Fig. 9 and Fig.10 As shown, the hole and slot cleaning mechanism includes a cleaning control bracket 5 arranged at the end of the cleaning closing arm 3, and a fan filter sleeve 51 is rotatably connected in the cleaning control bracket 5. A fixedly installed filter net can be used at the air inlet and air outlet of the fan filter sleeve 51 to block flying waste chips during the operation of the cleaning fan 31. A servo motor 52 for driving the cleaning fan 31 is fixed in the fan filter sleeve 51, and a cluster sleeve 53 is fixed on the side of the cleaning control bracket 5 close to the workpiece clamping seat 12.

[0030] It should be noted that: when cleaning the table top, the cleaning closing arm 3 is driven by the worm gear drive assembly to tilt toward the workbench 1, and when the cleaning closing arm 3 is tilted to the maximum angle, the servo motor 52 is started to drive the cleaning fan 31 to rotate, so that at the bottom of the cleaning control bracket 5 after the turning, a cleaning airflow is generated by the cleaning fan 31 and blown toward the table top of the workbench 1, driving metal chips and cutting fluid into the cleaning table 2. This is the table top cleaning process. When cleaning the holes and slots, the cluster sleeve 53 is used to limit the direction of the airflow generated by the rotation of the cleaning fan 31, so that the wind force generated by multiple cleaning fans 31 can clean the table top and clean the holes and slots of the metal workpiece at the same time. This is the hole and slot cleaning process; Furthermore, a fan inclination control arc groove is provided on the inner wall of the cleaning control bracket 5, a fan inclination fixing electromagnet 54 is provided in the fan inclination control arc groove, a fan filter sleeve 51 is fixed with an inclination locking column 511 slidably connected to the fan inclination control arc groove on the outer side, and a inclination ventilation groove is provided on the surface of the cluster sleeve 53, so as not to block the wind force in the swinging direction of the cleaning fan 31; It should be noted that: during the cleaning process of the table, the single-direction inclination fixing electromagnet 54 is turned on to adsorb the inclination locking column 511 set on the clockwise side of the plurality of fan filter sleeves 51, so that the fan filter sleeves 51 rotate, and the airflow direction of the driving cleaning fan 31 is adjusted, so that a vortex-type descending airflow can be formed at the bottom of the cleaning control bracket 5, and the metal chips and cutting fluid on the top of the workbench 1 can be driven away from multiple angles; Based on the above, after the cleaning fan 31 has been working for a period of time, the inclination fixing electromagnet 54 is turned on in another direction, so that the inclination locking column 511 arranged on the counterclockwise side of the plurality of fan filter sleeves 51 can be adsorbed, so that the fan filter sleeves 51 rotate in the opposite direction, and a vortex-type descending airflow opposite to the previous one is generated, so that the metal chips that could not be cleaned in the previous vortex airflow direction are cleaned, thereby improving the cleaning ability of the cleaning fan 31 for the metal chips on the table surface; Further based on the above, when the hole grooves of the metal workpiece clamped on the workbench 1 are cleaned by wind, the cleaning fans 31 in various directions can be started in turn to form cleaning wind forces in different directions, and the wind force can be converged by the clustering sleeve 53 to concentrate on multi-angle wind cleaning of the hole grooves of the metal workpiece placed in the central area of ​​the top of the workbench 1, so that the metal chips adhering to the hole grooves can be cleaned to the cleaning table 2 and collected.

[0031] Furthermore, a closing slide 55 is slidably arranged inside the cleaning control bracket 5, and the closing slide 55 is provided with ventilation holes, and the bottom of the closing slide 55 is closed by a support spring 551. When the cleaning control bracket 5 is attached to a closing seat arranged on the outer side of the cleaning table 2, the support spring 551 will squeeze the closing slide 55 upward, and store the ventilation holes into the cleaning control bracket 5, completing the operation of closing the ventilation holes. When the cleaning control bracket 5 is rotated toward the workbench 1 to the maximum inclination angle through the cleaning closing arm 3, the closing slide 55 will squeeze the metal workpiece processing tool and the support spring 551 to open the ventilation holes, so as to facilitate the cleaning of the table surface and the hole grooves of the metal workpiece when the cleaning fan 31 is turned on.

[0032] It should be noted that: a disentanglement groove 552 is provided on the top of the closing slide plate 55, and when the cleaning closing arm 3 rotates to the workbench 1 to the maximum inclination angle, a disentanglement hole is formed to clamp and clean the metal scrap wires entangled on the metal workpiece processing tool; Based on the above, when the closed slides 55 are brought close to each other, they can fit onto the outer surface of the metal workpiece processing tool through the unwinding groove 552 to clamp the metal chips wrapped around the outer surface of the tool, and then by moving the metal workpiece processing tool upward, the metal chips can be pulled out from the tool surface, thereby completing the cleaning operation of the metal chips of the metal workpiece processing tool.

[0033] Working principle: When the present invention cleans the metal chips generated during the processing of the metal workpiece, it is divided into three working processes: table metal chip cleaning, metal workpiece hole groove metal chip cleaning and metal chip and cutting fluid collection and separation. The table metal chip cleaning and metal workpiece hole groove metal chip cleaning processes are both provided with driving force by the worm and worm gear drive assembly, and the generation and wind direction of the cleaning wind are controlled by the control device in the cleaning control bracket 5.

[0034] Based on the above, the driving process of the worm gear drive assembly is as follows: when the stepper motor 4 is started to rotate clockwise, the driving worm 41 will be driven to rotate in the same direction, so that the driving worm wheel 42 meshing with the driving worm 41 will rotate, driving the cleaning and closing arm 3 to rotate. Based on this, when the stepper motor 4 is started to rotate in the opposite direction, the cleaning and closing arm 3 will be driven to rotate in the opposite direction, so that the inclination angle of the cleaning and closing arm 3 can be controlled by the rotation direction and rotation angle of the stepper motor 4, thereby controlling whether the collecting port on the cleaning table 2 is closed or not, and providing driving force for the inclination of the cleaning control bracket 5.

[0035] Based on the above, the cleaning process of the metal shavings on the table is as follows: during the cleaning process of the table, the inclined fixed electromagnet 54 on one side is turned on, so that the inclined locking column 511 set on the clockwise side of the multiple fan filter sleeves 51 can be adsorbed, so that the fan filter sleeves 51 rotate, and the airflow direction of the driving cleaning fan 31 is adjusted, so that a vortex downward airflow can be formed at the bottom of the cleaning control bracket 5, that is, the multiple inclined cleaning fans 31 generate a downward converging vortex airflow, which can drive away the metal shavings and cutting fluid on the top of the workbench 1 at multiple angles; Further based on the above, after the cleaning fan 31 has been working for a period of time, by turning on the inclination fixing electromagnet 54 on the other side, the inclination locking column 511 set on the counterclockwise side of the plurality of fan filter sleeves 51 can be adsorbed, so that the fan filter sleeves 51 rotate in the opposite direction, generating a vortex downward airflow opposite to the previous one, and cleaning the metal chips that could not be cleaned in the previous vortex airflow direction, thereby improving the cleaning ability of the cleaning fan 31 for the metal chips on the table.

[0036] Based on the above, the cleaning process of metal chips in the holes and grooves of metal workpieces is as follows: when the holes and grooves of the metal workpiece clamped on the workbench 1 are cleaned by wind, the cleaning fans 31 in various directions can be started in turn to form cleaning wind forces in different directions, and the wind forces can be converged by the clustering sleeve 53 to concentrate on multi-angle wind cleaning of the holes and grooves of the metal workpiece placed in the central area of ​​the top of the workbench 1, so that the metal chips adhering to the holes and grooves can be cleaned to the cleaning table 2 and collected.

[0037] Based on the above, the process of collecting and separating metal chips and cutting fluid is as follows: when metal chips fall through the collection port, the metal chips are blocked by the chip cleaning net 21, and the airflow passing through the metal chips is guided by the rotary sleeve 22, so that the atomized cutting fluid can enter the cutting fluid cleaning concentrator 23, and the cutting fluid therein is separated while the metal chips are cleaned, thereby reducing the processing steps of the cutting fluid after cleaning, and achieving the effect of improving the cleaning efficiency; Based on the above, when there is less metal scraps, the airflow generated by the cleaning fan 31 provides driving force for the inclined blades 241, driving the accumulated vortex bars 242 to rotate, and a small amount of metal scraps are concentrated on the outer wall of the upper ventilation sleeve 222, so as to prevent the small amount of scraps from directly adhering to the air inlet at the bottom of the lower ventilation sleeve 221, thereby blocking subsequent metal scraps and reducing the amount of metal scraps collected, thereby achieving the effect of improving the metal scrap blocking rate of the scrap cleaning net 21; Based on the above, when the metal waste is accumulated to a certain amount on the outer wall of the upper ventilation sleeve 222 through the accumulation vortex bars 242, and the waste collection amount between the lower ventilation sleeve 221 and the upper ventilation sleeve 222 is saturated, the metal waste will block the through hole of the waste cleaning net 21 located on the outside of the rotating sleeve 22, and act as a filter filler for capturing the atomized cutting fluid. Then, the rotating sleeve 22 is rotated to increase the flow path of the cleaning airflow, so that the downward airflow of the cleaning fan 31 through the collection port first passes through the bottom of the lower ventilation sleeve 221, and then passes through the top of the upper ventilation sleeve 222, and enters the cutting fluid cleaning concentration pipe 23, thereby cooperating with the blocked metal waste to increase the capture capacity of the atomized cutting fluid, thereby accelerating the dissipation speed of the atomized cutting fluid in the metal workpiece processing area, so that subsequent workers can place the next workpiece in an environment without atomized cutting fluid blocking their sight.
