Description

Technical Field

[0002] Milling is a method of cutting workpieces using a rotating multi-edged tool (i.e., milling cutter). It is one of the most common machining processes in mechanical manufacturing and is mainly used for machining planes, grooves, step surfaces, gears, threads, and various complex curved surfaces. With the development of industrial manufacturing technology, the machining accuracy and efficiency requirements for complex parts are becoming increasingly higher. During the milling process, if the waste chips generated cannot be removed in time, they may be re-mixed into the machining area, affecting the surface quality and machining accuracy of the workpiece, and may even cause damage to the tool or scrapping of the workpiece.

[0037] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0038] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0039] Embodiment 1: A vertical milling machine for machining hydraulic pump housing parts with automatic material removal, such as Figure 1-Figure 4 As shown, it includes a base 1 and a machine tool housing 2. The base 1 is an assembly load-bearing carrier of the vertical milling machine. The machine tool housing 2 is a square housing as a whole and has an opening in the front for placing a workpiece 100. A door panel 21 is symmetrically hingedly installed at the opening of the machine tool housing 2. A machine tool spindle 3 for lifting is provided in the upper part of the machine tool housing 2. An electrically driven milling cutter chuck 4 is installed at the bottom of the machine tool spindle 3. A milling cutter is clamped and installed on the milling cutter chuck 4. It also includes:

[0040] The sliding guide rail 5 is fixed to the lower part of the inner wall of the machine tool housing 2;

[0041] A mounting block 6 is slidably mounted on the sliding guide rail 5;

[0042] A three-jaw chuck 7 is rotatably mounted on the top of the mounting block 6. The three-jaw chuck 7 is used to adaptively clamp workpieces 100 of different sizes;

[0043] The chip removal assembly 8 is arranged inside the machine tool housing 2. The chip removal assembly 8 is used to synchronously absorb the chips generated when the workpiece 100 is milled. The chip removal assembly 8 includes: a conical cover 81, which is fixedly arranged at the bottom of the machine tool spindle 3. The top of the conical cover 81 is sealed and covers the periphery of the milling cutter chuck 4; a connecting pipe 82, which is provided with two and symmetrically fixed on the outer shell of the machine tool housing 2, and an electric turbine 84 is installed at one end of the connecting pipe 82. The two connecting pipes 82 are connected to the conical cover 81 through a corrugated telescopic pipe 83; a collecting box 85, which is provided with two and symmetrically installed on the outer shell of the machine tool housing 2. The other end of the connecting pipe 82 is connected to the corresponding collecting box 85 on the same side through a guide pipe 87, and the top of the collecting box 85 is provided The exhaust filter plate 86 is used to filter out debris. When the milling machine uses a preset program to control the lifting and lowering of the machine tool spindle 3 and drives the milling cutter on the milling cutter chuck 4 to rotate and mill the workpiece 100, the conical cover 81 synchronizes the lifting and lowering of the machine tool spindle 3 and is close to and covers the outside of the workpiece 100, and the electric turbines 84 at two locations are synchronously activated. The electric turbines 84 rotate at high speed and generate a negative pressure area in the connecting pipe 82. The negative pressure is transmitted to the conical cover 81 through the airflow and generates suction, so that the debris generated by the workpiece 100 during milling is sucked into the connecting pipe 82 through the corrugated telescopic tube 83 and enters the collecting box 85 with the airflow, wherein the gas is discharged from the exhaust filter plate 86, and the debris mixed in the airflow will be filtered out and collected in the collecting box 85.

[0044] like Figure 1-Figure 3 As shown, the collection boxes 85 are snap-fit ​​detachably installed on both sides of the machine tool housing 2, and the collection boxes 85 and the corresponding guide pipes 87 are detachably connected. By removing the collection box 85 from the machine tool housing 2, it is convenient to clean the debris collected in the collection box 85, and clean and maintain the collection box 85 and the exhaust filter plate 86.

[0045] like Figure 2 and Figure 7 As shown, a second motor 71 is fixedly installed inside the mounting block 6, and the output shaft of the second motor 71 is connected to the central rotating shaft of the three-jaw chuck 7. The second motor 71 drives the workpiece 100 on the three-jaw chuck 7 to rotate, which can improve the efficiency of processing the workpiece 100 at different positions. The nozzles 94 at two locations are both tilted downward and penetrated and installed on the corrugated telescopic cover 91. The nozzles 94 at two locations are symmetrically distributed on both sides of the three-jaw chuck 7. The nozzles 94 at two locations are used to synchronously blow air to the workpiece 100 and the dead corners of debris of the three-jaw chuck 7, thereby improving the efficiency of removing processing debris.

[0046] like Figure 5 and Figure 6As shown, two screw rods 51 are symmetrically installed inside the machine tool housing 2 for rotation, and the screw rods 51 at the two locations are symmetrically distributed on the front and rear sides of the sliding guide rail 5. Two first motors 52 are symmetrically fixedly installed on the front and rear sides of the top of the sliding guide rail 5, and the output shafts of the two first motors 52 are connected to the corresponding screw rods 51 on the same side. Fixed blocks 61 are fixed on the front and rear sides of the mounting block 6, and the screw rods 51 are respectively threadedly matched with the fixed blocks 61 on the same side of the mounting block 6 to synchronously activate the two first motors 52. The first motor 52 drives the mounting block 6 to slide on the sliding guide rail 5 through the synchronous thread of the screw rod 51, thereby improving the flexibility of machining the workpiece 100 on the three-jaw chuck 7.

[0047] When using the vertical milling machine to perform milling processing on a workpiece 100, the operator first rotates and opens the door panel 21 of the machine tool housing 2, then puts the workpiece 100 to be processed into the three-jaw chuck 7 for fixed clamping, and assembles the milling cutter onto the milling cutter chuck 4. The operator operates the control system of the entire vertical milling machine. The vertical milling machine controls the machine tool spindle 3 to rise and fall through a preset control program. The machine tool spindle 3 will drive the electrically driven milling cutter chuck 4 and the milling cutter thereon to descend to the surface of the workpiece 100 for milling operation. At the same time, the conical cover 81 is lowered together with the machine tool spindle 3 and is close to the workpiece 100, and covers the periphery of the workpiece 100 on the three-jaw chuck 7 from top to bottom. Under program control, when the electrically driven milling cutter performs milling processing on the workpiece 100, the electric turbine 84 is activated to generate a high-speed airflow in the connecting pipe 82 to the guide pipe 87 and form a negative pressure zone, and the generated negative pressure is transmitted to the conical cover 81 through the bellows expansion pipe 83, so that the metal debris generated at the workpiece 100 during the milling process will be removed by the conical cover 81. The suction force is applied to the workpiece 100, and the sucked debris passes through the bellows expansion pipe 83 and the connecting pipe 82, and finally enters the collection box 85 from the guide pipe 87. Since the top of the collection box 85 is provided with an exhaust filter plate 86, the circulating gas is discharged from it, and the debris brought out by the air flow is filtered by the exhaust filter plate 86 and remains in the collection box 85, so that the produced debris can be cleaned efficiently and automatically while the workpiece 100 is being milled, and the collection box 85 with the collected debris can be removed from the machine tool housing 2 for convenient cleaning. During the milling process of the workpiece 100, the workpiece 100 on the three-jaw chuck 7 is driven to rotate by the second motor 71, and the milling cutter on the machine tool spindle 3 is lifted and lowered, so that the milling cutter can process at a specific position of the workpiece 100. When the processing position of the workpiece 100 needs to be adjusted, the first motors 52 at two locations are synchronously activated. The first motor 52 drives the mounting block 6 to slide on the sliding guide rail 5 through the screw rod 51 thread, so that the workpiece clamped on the three-jaw chuck 7 can flexibly adjust the processing position left and right.

[0048] like Figure 3 , Figure 5 and Figure 7As shown, a chip flushing assembly 9 for assisting chip removal is provided inside the machine tool housing 2, and the chip flushing assembly 9 includes:

[0049] The bellows telescopic cover 91 is fixedly assembled on the top of the mounting block 6. The bellows telescopic cover 91 covers the periphery of the three-jaw chuck 7. The bellows telescopic cover 91 has telescopic properties.

[0050] The electric push rods 92 are provided with two and symmetrically fixedly installed on both sides of the top of the mounting block 6. The two electric push rods 92 are distributed on the left and right sides of the bellows telescopic cover 91. The push rods of the electric push rods 92 are fixedly connected with connecting plates 93. The two electric push rods 92 are connected to the bellows telescopic cover 91 through the connecting plates 93.

[0051] There are two nozzles 94, which are symmetrically mounted on the bellows telescopic cover 91;

[0052] The pressure pumps 95 are the same in number as the nozzles 94 and are symmetrically fixedly mounted on the outer shell of the machine tool housing 2;

[0053] The bracket 96 is symmetrically fixed on the inner wall of the rear side of the machine tool housing 2; the first hose 97 is symmetrically arranged inside the machine tool housing 2 through the bracket 96, one end of the first hose 97 is connected to the outlet of the corresponding pressure pump 95 on the same side, and the other end of the first hose 97 is connected to the corresponding nozzle 94 on the same side. When the conical cover 81 follows the machine tool spindle 3 to descend and cover the periphery of the processed workpiece 100, the push rod of the electric push rod 92 extends and drives the corrugated telescopic cover 91 to extend and approach The conical cover 81 enables the milling cutter to perform milling processing in the relatively closed space between the conical cover 81 and the corrugated telescopic cover 91, thereby reducing the splashing of processing debris. At the same time, the pressure pump 95 draws external air into the first hose 97, and the drawn airflow flows into the corresponding nozzle 94 through the first hose 97. The nozzle 94 can blow up the debris stuck on the workpiece 100 or the three-jaw chuck 7, so that the debris that is difficult to be sucked away in the processing dead corners can be sucked away by the conical cover 81.

[0054] In order to further improve the chip removal efficiency, especially in the hard-to-reach processing dead corners, the chip flushing assembly 9 can be activated. When the conical cover 81 approaches the workpiece 100 and starts the milling operation, the electric push rods 92 are activated, and the push rods of the electric push rods 92 at two locations are extended and drive the corrugated telescopic cover 91 to extend. The driven corrugated telescopic cover 91 extends upward and gradually fits the conical cover 81 that moves downward with the spindle 3 of the machine tool, ensuring that the milling area where the workpiece 100 is located is as closed as possible. At this time, the pressure pump 95 draws in external air and transports it to the corresponding nozzle 94 through the first hose 97. The nozzle 94 sprays high-pressure gas directly to the workpiece 100 and the three-jaw chuck 7. The areas where debris is likely to remain, so that the debris in these dead corners can be lifted and suspended between the conical cover 81 and the corrugated telescopic cover 91, and the suspended debris can be more effectively sucked away by the conical cover 81, thereby improving the removal effect of the debris generated during processing.

[0055] Embodiment 2: Based on embodiment 1, Figure 5 and Figure 8 As shown, a liquid storage box 10 is fixedly provided on the top of the machine tool housing 2, and the liquid storage box 10 is used to store cutting fluid. A joint frame 11 is provided at the inlet of the pressure pump 95, and only one opening connected to the inlet of the pressure pump 95 is provided in the joint frame 11. A second hose 13 is connected to the liquid storage box 10, and the outlet end of the second hose 13 is slidably provided in the joint frame 11. When cutting fluid needs to be added during the milling process, the second hose 13 is slid on the joint frame 11 so that the outlet end of the second hose 13 can be connected to the opening of the joint frame 11, so that the cutting fluid can flow into the pressure pump 95, and then flow through the first hose 97 and then be sprayed from the nozzle 94 to the workpiece 100, so that the pressure pump 95 can flexibly switch between the two states of pumping gas and conveying cutting fluid.

[0056] like Figure 5 and Figure 8 As shown, a rubber valve 12 is also provided at the outlet of the second hose 13. The rubber valve 12 is composed of a rubber film that is closed in three directions at the outlet of the second hose 13. The rubber valve 12 fits tightly in the joint frame 11. When the second hose 13 is connected to the opening of the joint frame 11, the rubber valve 12 can ensure a sealed connection between the second hose 13 and the joint frame 11 under the action of the air pressure of the pressure pump 95. When the second hose 13 is not connected to the joint frame 11, the rubber valve 12 can prevent the cutting fluid from leaking between the joint frame 11 and the second hose 13.

[0057] like Fig. 9As shown, a recovery pump 14 is installed at the inner bottom of the liquid storage box 10, and a reflux pipe 15 is connected to the inlet of the recovery pump 14. A reflux box 16 is provided at the inner bottom of the machine tool housing 2, and a filter screen 17 is provided on the outer wall of the reflux box 16. The reflux pipe 15 is sealed and connected to the reflux box 16. The recovery pump 14 generates suction in the reflux box 16 through the reflux pipe 15, so that the cutting fluid flowing into the inner bottom of the machine tool housing 2 can be filtered by the filter screen 17 to remove debris, and then flow back to the liquid storage box 10 through the reflux box 16 and the reflux pipe 15 for recycling.

[0058] In addition, when it is necessary to use cutting fluid to assist the workpiece 100 in milling, the operator can manually slide the second hose 13 to accurately connect the rubber valve 12 at the outlet end of the second hose 13 to the opening position of the joint frame 11, and then activate the pressure pump 95. Under the action of the pressure pump 95, the rubber valve 12 is opened by air pressure, and the opened rubber valve 12 can fit tightly at the opening of the joint frame 11, so that the cutting fluid can be sealed and smoothly flow into the pressure pump 95. Similarly, the cutting fluid is transmitted to the nozzle 94 through the first hose 97, and finally the nozzle 94 evenly sprays the cutting fluid onto the workpiece 100, thereby improving the processing quality of the workpiece 100. When the cutting fluid is not needed, only the second hose 13 needs to be slid open. When the 3-port rubber valve 12 is removed from the opening of the joint frame 11, the pressure pump 95 can continue to pump in clean air. When a certain amount of cutting fluid is collected at the bottom of the machine tool housing 2, the recovery pump 14 is activated. The recovery pump 14 is connected to the reflux box 16 through the reflux pipe 15. During the processing, the cutting fluid mixed with debris that flows to the bottom of the machine tool housing 2 can be sucked back into the fluid storage box 10 for use. In the process of the cutting fluid flowing into the reflux box 16, the cutting fluid mixed with debris will be filtered by the filter plate 17, so that the debris in the cutting fluid is effectively removed before entering the reflux box 16, and then pumped back to the fluid storage box 10 through the reflux pipe 15, thereby ensuring the cleanliness and reuse value of the recovered cutting fluid.

[0059] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
