Description

Technical Field

[0001] The invention belongs to the technical field of milling machines, and in particular relates to a milling machine for tool processing. Background Art

[0002] A milling machine mainly refers to a machine tool that uses a milling cutter to process various surfaces of a workpiece. Usually, the milling cutter mainly moves in rotation, and the movement of the workpiece and the milling cutter is the feed motion. It can process planes, grooves, various curved surfaces, gears, etc. In short, a milling machine is a widely used machine tool that can perform milling, drilling and boring on workpieces.

[0003] In the prior art, a Chinese invention patent with patent number CN118287731A discloses a milling machine for jig processing, including a frame, a moving mechanism is arranged on the top surface of the frame, a carrier is fixedly installed on the top surface of the moving part of the moving mechanism, a processing table is fixedly installed on the top surface of the carrier, a gantry is fixedly installed on the top surface of the frame, and a position adjustment mechanism is arranged on the side wall of the gantry. The present invention sprays the cutting fluid in the chip liquid storage assembly onto the surface of the milling cutter through a cooling mechanism, thereby cooling the milling cutter and the jig blank, and the cutting fluid and the chips are mixed and dropped during cutting, and the cutting fluid and the chips are separated through a filtering and collecting net, so that the chips in the cutting fluid are filtered and then flow back to the inside of the chip liquid storage assembly, and the chips accumulated on the top surface of the filtering and collecting net can be discharged through a discharge port on a side wall of the chip liquid storage assembly.

[0004] In the prior art, the debris accumulated on the top surface of the filter collection net can be discharged through the discharge port on one side wall of the chip liquid storage assembly, but there are still some shortcomings in the overall use: First, the workpiece is placed on the processing table, which is set on the top of the frame and exposed to the outside. When the workpiece is processed, the nozzle sprays the cutting fluid on it. At this time, the cutting fluid is sprayed on the milling cutter and the workpiece, and a part of the mixed liquid will fall, but this will cause a part of the mixed liquid to splash out, adhere to other parts, cause sluggish operation, and may even splash out, causing pollution to the surrounding environment and waste of cutting fluid; Secondly, in the above scheme, when the cutting fluid is filtering the processing debris, only the filter collection net is used for filtering, which will lead to poor filtering effect, and the processing debris may also block the filter holes of the filter collection net, which cannot be cleaned during the processing, greatly reducing the filtering effect, and the equipment needs to be disassembled for cleaning and collection, which greatly reduces the work efficiency; Finally, the cutting fluid nozzle moves with the milling cutter. Due to the centrifugal force generated by the high-speed rotation of the milling cutter, the cutting fluid has already vaporized before reaching the cutting area and cannot play a role in cooling, lubricating and chip removal. This not only reduces the cutting efficiency, but may also increase the wear of the tool. Summary of the invention

[0005] The present invention provides a milling machine for tool processing in order to solve the technical problems that cutting splash affects the normal operation of equipment and wastes costs, and that only using a filter collection net for filtering will lead to poor filtering effect, may also cause processing debris to block the filter holes of the filter collection net, and increase the wear of the tool.

[0006] In order to achieve the above-mentioned object, the present invention provides the following technical solutions: A milling machine for jig processing, comprising a base, a box body is fixedly installed on the upper surface of the base, a first filter plate is arranged in the inner cavity of the box body for initial filtering of cutting fluid, and a fixing assembly is fixedly installed in the middle of the inner cavity of the box body for fixing a workpiece; A mounting plate is fixedly mounted on the inner walls of both sides of the box, and a dual-axis motor is fixedly mounted on the lower surface of the mounting plate. A first moving assembly is arranged at the upper output end of the dual-axis motor, and a nozzle for spraying cutting fluid is rotatably mounted on one side of the first moving assembly, and the first moving assembly drives the nozzle to reciprocate up and down to spray the cutting fluid; The first moving assembly is rotatably mounted with a rotating shaft, and a fixing ring for fixing the nozzle is fixedly mounted on the other end of the rotating shaft, and a torsion spring penetrated by the rotating shaft is fixedly mounted between the fixing ring and the first transmission assembly, and the torsion spring is used to adjust the angle of the nozzle and reset it; The lower output end of the dual-axis motor is provided with a second moving component, the lower surface of the second moving component is provided with a first magnet plate used in conjunction with the first filter plate, and the second moving component drives the first magnet plate to reciprocate to clean up debris.

[0007] The nozzle is driven to move by the first moving component. During the movement of the nozzle, the nozzle slowly rotates and tilts downward, so that the nozzle can fully spray the workpiece and the milling cutter, greatly improving the lubrication and cooling effects of the cutting fluid. At the same time, the second moving component drives the first magnet plate to move, absorbs and cleans the processing debris filtered on the first filter plate, prevents the processing debris from clogging the first filter plate, and greatly improves the filtering effect.

[0008] In the above-mentioned milling machine for jig processing, The first moving assembly comprises a fixing plate fixedly mounted on the inner walls of both sides of the box body, and a second screw driven by the output end of the fixing plate is rotatably mounted on the lower surface of the fixing plate; A first limiting rod is provided between the fixing plate and the mounting plate, and a second movable block is threadedly mounted on the surface of the second screw rod and is slidably matched with the first limiting rod; One side of the second movable block is used for rotatably mounting the rotating shaft.

[0009] The second movable block is limited by the first limiting rod, so that when the second screw rod rotates, the second movable block can slide on the first limiting rod.

[0010] In the above-mentioned milling machine for jig processing, The first moving assembly also includes a push rod fixedly mounted on the lower surface of the fixed plate, and the push rod is located on one side of the second screw rod. An arc-shaped pressure plate is fixedly mounted on the bottom end of the push rod, and the pressure plate is used to change the spraying angle when the nozzle moves.

[0011] When the nozzle moves upward and contacts the pressure plate, the nozzle is rotatably installed on one side of the second movable block, so that the nozzle rotates when it is under pressure, increasing the spraying angle, so that the cutting fluid can cover the milling cutter and the workpiece, and improving the use effect.

[0012] In the above-mentioned milling machine for jig processing, The second moving component includes a transmission shaft and a second limiting rod rotatably mounted on the inner walls on both sides of the box body, a third screw rod is fixedly mounted on one end of the transmission shaft, a third movable block that slides through and fits with the second limiting rod is threadedly mounted on the surface of the third screw rod, an electromagnet is fixedly mounted on the lower surface of the third movable block, and the first magnet plate is magnetically attracted to the lower surface of the electromagnet.

[0013] When the third screw rod rotates, the second limiting rod is limited, so that the third movable block drives the electromagnet to move, and the electromagnet generates magnetic force to absorb the first magnet plate, thereby driving the first magnet plate to move.

[0014] In the above-mentioned milling machine for jig processing, The second moving assembly also includes a first bevel gear fixedly mounted on the fixing ring and a second bevel gear fixedly mounted on the lower output end of the dual-axis motor, and the first bevel gear is meshed with the second bevel gear.

[0015] In the above-mentioned milling machine for jig processing, Rings used in conjunction with the third screw rod and the second limiting rod are fixedly mounted on both sides of the third movable block, and the rings are used to remove debris remaining on the surfaces of the third screw rod and the second limiting rod.

[0016] By setting the collar, as the third movable block moves, the debris remaining on the surface of the third screw rod and the second limit rod is removed, preventing the processing debris from affecting the movement of the third movable block.

[0017] In the above-mentioned milling machine for jig processing, The fixing assembly comprises an electric telescopic rod fixedly mounted in the middle of the inner cavity of the box body, a support platform is fixedly mounted on the output end of the electric telescopic rod, and a return air outlet is opened on the upper surface of the support platform.

[0018] Through the setting of the air outlet, the workpiece can be quickly fixed and the processing speed can be improved. At the same time, through the setting of the electric telescopic rod, the support platform and the workpiece can be driven down into the box, which is convenient for collecting the debris during the workpiece processing and the cutting oil sprayed during the processing.

[0019] In the above-mentioned milling machine for jig processing, A movable groove is fixedly installed on the top inner wall of the box body, a first screw rod is rotatably installed inside the movable groove, and a bracket is threadedly installed on the surface of the first screw rod; A threaded rod is rotatably mounted on the middle and upper part of the bracket, and a top plate is fixedly mounted on the top of the bracket, and a second sliding groove is provided on the front surface of the top plate; A first movable block is threadedly mounted on the surface of the threaded rod, and an L-shaped plate sliding inside the second sliding groove is fixedly mounted on the front surface of the first movable block.

[0020] When the first screw rotates, the bracket slides in the movable groove, so that the left and right position of the milling cutter can be adjusted. When the threaded rod rotates, the first movable block slides in the second sliding groove, so that the milling cutter can be adjusted forward and backward, thereby improving the processing accuracy of the workpiece.

[0021] In the above-mentioned milling machine for jig processing, A cylinder is fixedly installed on the top of the L-shaped plate, and a third slide groove is opened on the front surface of the L-shaped plate. A support plate is slidably installed in the third slide groove, and the upper surface of the support plate is fixed to the output end of the cylinder. A milling cutter is arranged on the surface of the support plate.

[0022] Through the setting of the cylinder, the L-shaped plate can be driven to slide in the third slide groove, so that the milling cutter can be adjusted up and down, further improving the processing accuracy.

[0023] In the above-mentioned milling machine for jig processing, A second filter plate is arranged in the inner cavity of the box body and below the first filter plate, and a second magnet plate is arranged below the second filter plate.

[0024] The setting of the second filter plate can further improve the filtering effect.

[0025] In summary, compared with the prior art, the milling machine for jig processing provided by the present invention has the following beneficial effects: 1. The present invention is provided with a movable rotating nozzle, a first movable assembly, a second movable assembly, a first magnet plate and a first filter plate. When the workpiece is processed, the nozzle moves up and down and rotates downward to increase the spraying angle of the nozzle, so that the cutting fluid can be completely sprayed on the workpiece and the milling cutter, fully playing the role of cooling and lubricating, greatly improving the use effect of the milling machine, and at the same time, in the process of spraying the cutting fluid, the filter plate for filtering the cutting fluid can be cleaned and processing debris can be collected to prevent the processing debris from clogging the filter hole during the workpiece processing, thereby greatly improving the filtering effect; 2. The present invention uses a fixing assembly and other settings to allow the workpiece to be adsorbed on the workbench by means of negative pressure. The fixing method is simple and convenient, and the fixing is accurate and firm, which greatly improves the processing efficiency and precision. 3. The present invention sets the nozzle and the milling cutter separately to prevent the centrifugal force generated by the high-speed rotation of the milling cutter, so that the cutting fluid is vaporized before reaching the cutting area, and cannot play the role of cooling, lubricating and chip removal, which increases the wear of the tool and greatly improves the use effect of the milling machine.

DETAILED DESCRIPTION

[0028] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Embodiment 1:

[0029] refer to Figure 1 and Figure 4 A milling machine for jig processing includes a base 10, a box 11 is fixedly installed on the upper surface of the base 10, and is used to collect debris and cutting oil generated when processing a workpiece. A controller 12 of a control device is fixedly installed on the front surface of the box 11, and an electric telescopic rod 28 is fixedly installed in the middle of the inner cavity of the box 11. The electric telescopic rod 28 is a prior art and will not be elaborated in this scheme. A support 29 for placing a workpiece is fixedly installed on the top of the electric telescopic rod 28, and a circular air outlet 30 is opened on the upper surface of the support 29, and a negative pressure fan is arranged inside the support 29. The negative pressure fan is a prior art and will not be elaborated in this scheme.

[0030] Specifically, during processing, the workpiece is placed on the support platform 29, and then the negative pressure fan is started, thereby forming a downward suction force at the circular air outlet 30, so that the workpiece can be adsorbed on the end face of the support platform 29, making the workpiece fixation more convenient and improving work efficiency. Then, the output end of the electric telescopic rod 28 is controlled to move downward, thereby driving the support platform 29 and the workpiece to move down into the box body 11, which is convenient for collecting the debris during workpiece processing and the cutting oil sprayed during processing.

[0031] Further, refer to Figure 1 and Figure 2A symmetrical moving groove 13 is fixedly installed on the top inner wall of the box body 11, a first screw rod 14 is rotatably installed inside the moving groove 13, a bracket 16 is threadedly installed on the surface of the first screw rod 14, and a first servo motor 15 that drives the first screw rod 14 is fixedly installed on one side of the box body 11.

[0032] Specifically, the output end of the first servo motor 15 can drive the first screw rod 14 to rotate, thereby driving the bracket 16 disposed on the first screw rod 14 to move left and right in the moving groove 13 .

[0033] Further, refer to Figure 1 and Figure 2 A top plate 17 is fixedly installed on the top of the bracket 16, and a threaded rod 18 is fixedly installed between the two brackets 16. A second servo motor 19 that drives the threaded rod 18 is fixedly installed on one side of the bracket 16. A second slide groove 20 is opened on the front surface of the top plate 17. A first movable block 21 is threadedly installed on the surface of the threaded rod 18. An L-shaped plate 22 that slides in the second slide groove 20 is fixedly installed on the surface of the first movable block 21.

[0034] Specifically, the output end of the second servo motor 19 can drive the threaded rod 18 connected thereto to rotate, so that the first movable block 21 drives the L-shaped plate 22 to move forward and backward in the second sliding groove 20 .

[0035] Further, refer to Figure 1 and Figure 3 A symmetrical third slide groove 24 is provided on the front surface of the L-shaped plate 22, a cylinder 23 is fixedly installed on the top of the L-shaped plate 22, the output end of the cylinder 23 passes through the L-shaped plate 22 and is slidably fitted, and a support plate 25 sliding in the third slide groove 24 is fixedly installed on the bottom end, a spindle motor 26 is fixedly installed on the lower surface of the support plate 25, and a milling cutter 27 for processing a workpiece is fixedly installed on the output end of the spindle motor 26.

[0036] Specifically, the cylinder 23 drives the support plate 25 to slide inside the third slide groove 24, thereby driving the milling cutter 27 to move up and down, so as to process the workpiece. In conjunction with the use of the above-mentioned technical solution, the milling cutter 27 can move in all directions, thereby facilitating the processing of the workpiece. Embodiment 2:

[0037] refer to Figure 4 and Figure 7A mounting plate 31 and a fixing plate 33 are fixedly installed on both sides of the inner cavity of the box body 11, and the fixing plate 33 is located at the top of the box body 11. A dual-axis motor 32 is fixedly installed on the lower surface of the mounting plate 31. The dual-axis motor 32 is a servo motor, which is a prior art and will not be elaborated in detail in this scheme. A first limiting rod 34 is fixedly installed between the mounting plate 31 and the fixing plate 33, and a second screw rod 36 is also rotatably installed between the mounting plate 31 and the fixing plate 33. The second screw rod 36 is located on one side of the first limiting rod 34 and can be driven by the output end of the dual-axis motor 32. A second movable block 35 penetrated by the first limiting rod 34 is threadedly installed on the surface of the second screw rod 36, and is slidably matched with the first limiting rod 34.

[0038] Further, refer to Figure 7 and Figure 8 A rotating shaft 39 is rotatably installed on one side of the second movable block 35, a fixing ring 41 is fixedly installed on the other end of the rotating shaft 39, and a torsion spring 40 is installed through the rotating shaft 39. A nozzle 42 for spraying cutting oil is sleeved inside the fixing ring 41, and a retractable liquid inlet pipe 43 is connected to the liquid inlet end of the nozzle 42, and the other end of the liquid inlet pipe 43 passes through the outside of the box body 11.

[0039] Furthermore, refer to Figure 4 and Figure 7 A push rod 37 is fixedly mounted on the lower surface of the fixing plate 33 , and an arc-shaped pressing plate 38 used in conjunction with the nozzle 42 is fixedly mounted on the bottom end surface of the push rod 37 .

[0040] Specifically, when the output end of the dual-axis motor 32 rotates, it drives the second screw rod 36 connected thereto to rotate. When the second screw rod 36 rotates, the second movable block 35 slides upward when the first limit rod 34 is limited, thereby driving the nozzle 42 to move upward, so that the nozzle 42 sprays the workpiece and the milling cutter 27, which can cool and lubricate the workpiece during processing, effectively improving the processing effect, and at the same time can spray within the cutting range to settle debris and remove dust.

[0041] More specifically, when the nozzle 42 continues to move upward, the nozzle 42 will contact the bottom end surface of the pressure plate 38. At this time, when the nozzle 42 continues to move upward, the pressure plate 38 will press the nozzle 42. Since one end of the nozzle 42 is rotatably connected to the rotating shaft 39, the nozzle 42 will rotate downward at this time, so that the nozzle 42 can completely cool and lubricate the milling cutter 27 and the workpiece in all directions. The downward rotation of the nozzle 42 can enable the cutting fluid to be completely sprayed on the workpiece and the milling cutter 27. In this solution, if the nozzle 42 is parallel to the workpiece, the cutting fluid will be sprayed out of the box 11, causing pollution to the surrounding environment, causing waste of cutting fluid, and greatly increasing the cost of use. When the nozzle 42 moves downward, the torsion spring 40 can reset the nozzle 42.

[0042] Further, refer to Figure 4 , Figure 6 and Figure 7 A transmission shaft 44 is rotatably mounted on the inner walls of both sides of the box body 11, and a second limiting rod 51 is fixedly mounted thereon. A third screw rod 46 is fixedly mounted on one end of the transmission shaft 44 away from the inner wall of the box body 11. A second bevel gear 52 is fixedly mounted on the lower output end of the dual-axis motor 32. A first bevel gear 45 meshing with the second bevel gear 52 is fixedly mounted on the surface of the transmission shaft 44.

[0043] Specifically, when the dual-axis motor 32 rotates, the lower output end of the dual-axis motor 32 drives the second bevel gear 52 to rotate, thereby driving the third screw rod 46 connected thereto to rotate, so that the third screw rod 46 and the second screw rod 36 rotate simultaneously.

[0044] Furthermore, refer to Figure 4-Figure 6 A first filter plate 53 is fixedly installed in the inner cavity of the box body 11 for filtering the debris in the cutting fluid to achieve preliminary separation of the processing debris and the cutting fluid. The surface of the third screw rod 46 is threadedly installed with a third movable block 47 penetrated by the second limit rod 51. The third movable block 47 is slidably matched with the second limit rod 51, and the lower surface of the third movable block 47 is fixedly installed with an electromagnet 48. The electromagnet 48 is a prior art and will not be elaborated in detail in this scheme. A first magnet plate 49 parallel to the first filter plate 53 is magnetically installed on the lower surface of the electromagnet 48. The first magnet plate 49 is used to absorb the processing debris filtered by the first filter plate 53. The setting of the electromagnet 48 is convenient for disassembly from the first magnet plate 49, thereby facilitating the collection and treatment of processing debris and improving work efficiency.

[0045] Specifically, while the third screw rod 46 rotates, the third movable block 47 slides to the right under the limit of the second limit rod 51, so that the third movable block 47 drives the first magnet plate 49 to move, and then the first magnet plate 49 absorbs the processing debris left by filtering the cutting fluid on the first filter plate 53, preventing the processing debris from clogging the filter holes of the first filter plate 53 and affecting the filtering effect.

[0046] More specifically, the reciprocating rotation of the dual-axis motor 32 drives the nozzle 42 to move up and down to lubricate and cool the workpiece and the milling cutter 27, while the first magnet plate 49 moves left and right to absorb the processing debris that blocks the filter hole, thereby greatly improving the use effect of the milling machine.

[0047] Further, refer to Figure 6 Rings 50 are fixedly installed on both sides of the third movable block 47 for scraping off the machining debris remaining on the surface of the second limiting rod 51 and the third screw rod 46 to prevent the machining debris from affecting the sliding of the third movable block 47 and reducing the use effect.

[0048] Further, refer to Figure 4A second filter plate 54 fixedly installed in the inner cavity of the box body 11 is arranged below the first filter plate 53, which is used for further filtering the cutting fluid. A second magnet plate 55 is arranged below the second filter plate 54, which is used for absorbing the remaining processing debris after the cutting fluid is filtered and allowed to stand, so as to further ensure the purity of the cutting fluid after filtration and the use effect of the cutting fluid. A liquid outlet pipe 56 is connected to one side of the box body 11 for externally connecting to a cutting fluid conveying device. The cutting fluid conveying device is a prior art and will not be elaborated in detail in this scheme. The filtered cutting fluid can be passed into the nozzle 42 for reuse, which greatly reduces the cost.

Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction.
