Description

Technical Field

[0001] The present invention relates to the technical field of metal part processing, and more particularly, to a milling device for machining hydraulic parts. Background Art

[0002] Hydraulic parts, also known as hydraulic components or hydraulic assemblies, are the basic units that make up a hydraulic system. These components achieve the conversion between mechanical energy and hydraulic energy by controlling and transmitting liquid pressure, thereby driving the movement of various mechanical equipment. Hydraulic parts usually require very high precision and surface quality because these parts have to withstand high pressure during operation and it is necessary to ensure that the liquid medium does not leak. Therefore, there are strict requirements for the machining of hydraulic parts, especially the milling process.

[0003] The prior art discloses a milling processing device for metal parts (publication number: CN116037997B), which includes a device chassis. One side of the top of the device chassis is fixedly installed with a longitudinal frame. A indexing mechanism is provided in the middle of the longitudinal frame. A cutting tool is provided on the indexing mechanism. A driving mechanism and a cooling assembly are fixedly provided at the top of the longitudinal frame. The above-mentioned milling processing device realizes the rapid replacement of the tool through the indexing mechanism, thereby improving the milling processing efficiency of a single surface. However, there are certain limitations when processing workpieces that require multi-surface machining. Since only one surface of the workpiece can be machined at a time, for complex workpieces or workpieces with multiple machining surfaces, after machining one surface, the workpiece needs to be disassembled from the device, repositioned and clamped to machine other surfaces. This not only increases the operation time, but also each reinstallation will introduce potential position errors. Summary of the Invention

It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0029] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0030] Embodiment 1: A milling device for machining hydraulic parts, as Figures 1 - 5As shown in the figure, it includes a bottom frame 1. A support plate 2 is fixedly connected to the rear side of the bottom frame 1. A sliding frame 3 is slidably mounted on the upper part of the support plate 2 along the Z-axis direction through a guide rod 31. A hydraulic cylinder 4 is fixedly mounted on the side wall of the support plate 2, and the piston rod of the hydraulic cylinder 4 is connected to the sliding frame 3. It further includes: mounting seats 5, which are provided in two upper and lower ones and are respectively slidably mounted on the opposite end faces of the bottom frame 1 and the sliding frame 3 along the X-axis direction. A through hole is provided in the middle of the mounting seat 5. Chuck plates 6 are respectively slidably sleeved in the through holes of the mounting seats 5 for clamping the upper and lower sides of the workpiece. Mounting frames 62 are slidably mounted inside the mounting seats 5, and the mounting frames 62 are rotationally matched with the corresponding chuck plates 6. More than two electric push rods 63 are provided inside the mounting seats 5, and the push rods of the electric push rods 63 are connected to the corresponding mounting frames 62 for driving the mounting frames 62 to displace along the Z-axis direction. A driving mechanism 7 is arranged on the mounting seat 5 and is used for driving the chuck plates 6 to rotate, so as to rotate and adjust the workpiece clamped between the upper and lower chuck plates 6. Two electric slide rails 8 are provided and are symmetrically fixedly arranged on the left and right sides of the bottom frame 1. A slide table 9 is slidably mounted on the electric slide rails 8 along the X-axis direction, and a side milling mechanism 10 for milling the side surface of the workpiece is arranged on the slide table 9.

[0031] The hydraulic cylinder 4 drives the sliding frame 3 to vertically lift and lower, so that the mounting seats 5 on the bottom frame 1 and the sliding frame 3 clamp the placed workpiece through the chuck plates 6. Then, the electric slide rails 8 are used to drive the side milling mechanisms 10 on both sides to mill the side surface of the workpiece, and the driving mechanism 7 is used to synchronously drive the workpiece clamped between the chuck plates 6 to rotate, so as to mill different side surfaces of the workpiece.

[0032] As Figure 2 and Figure 4 As shown in the figure, the driving mechanism 7 includes: a toothed ring 71, which is rotatably mounted on the opposite end faces of the mounting seat 5. Tooth teeth are provided on the outer peripheral wall of the toothed ring 71. A plurality of vertically extending slide bars 61 are provided on the outer peripheral wall of the chuck plate 6. A limiting groove corresponding to the slide bar 61 is provided in the inner ring of the toothed ring 71. The chuck plate 6 is slidably sleeved inside the toothed ring 71 through the slide bar 61, and the chuck plate 6 is driven to rotate through the toothed ring 71. A gear 72 is rotatably mounted on the mounting seat 5, and the gear 72 meshes with the toothed ring 71 on the same mounting seat 5. A worm gear 73 is fixedly connected to the rotating shaft of the gear 72, and the worm gear 73 is located inside the mounting seat 5. A driving motor 74 is fixedly mounted inside the mounting seat 5, and a worm 75 is fixedly provided on the output shaft of the driving motor 74, and the worm gear 73 meshes with the worm 75.

[0033] The driving motor 74 drives the worm gear 73 to rotate through the meshing of the worm 75, so that the worm gear 73 synchronously drives the gear 72 to rotate. Finally, the gear 72 meshes and drives the toothed ring 71 and the corresponding chuck plate 6 to rotate, so as to accurately adjust the milling angle of the workpiece between the chuck plates 6. And due to the self-locking property of the worm gear 73 and the worm 75, the chuck plates 6 with the adjusted angle can stably clamp the workpiece.

[0034] As Figure 1 , Figure 2 , Figure 7 and Figure 8 shown, the side milling mechanism 10 includes: a first cylinder 101 fixedly installed on the sliding table 9; a first connecting block 102 fixedly connected to the piston rod of the first cylinder 101, and an installation inner cavity is provided inside the first connecting block 102; a first rotating shaft 103 penetrating and rotatably installed on the sliding table 9, the first rotating shaft 103 is rotationally matched with the first connecting block 102, and a first surface milling cutter 104 is fixedly provided on the end faces of the first rotating shafts 103 facing each other on the left and right; a first motor 105 fixedly installed in the installation inner cavity of the first connecting block 102, and the first motor 105 is connected to the first rotating shaft 103 through a coupling.

[0035] The first cylinder 101 drives the first rotating shaft 103 and the first surface milling cutter 104 to contact the workpiece inward through the first connecting block 102, and cooperates with the first motor 105 to drive the first surface milling cutter 104 of the first rotating shaft 103 to rotate, so as to achieve the grinding effect on each side surface of the workpiece in the circumferential direction.

[0036] Before milling the workpiece using this milling device, the operator first needs to adjust the position of the sliding frame 3 according to the size of the workpiece to be processed. Specifically, by enabling the hydraulic cylinder 4, when the piston rod of the hydraulic cylinder 4 extends and retracts, the piston rod of the hydraulic cylinder 4 drives the connected sliding frame 3 to move up and down along the guide rod 31, thereby changing the distance between the bottom frame 1 and the mounting seat 5 on the sliding frame 3 to ensure that workpieces of different heights or thicknesses can be accommodated. Then, the workpiece is placed at a suitable milling position between the upper and lower chucks 6. Next, the first electric push rod 63 is enabled. As the push rod of the first electric push rod 63 drives the chuck 6 on the mounting bracket 62 to lift within the through-hole of the corresponding mounting seat 5, the upper and lower chucks 6 come into close contact and firmly clamp the workpiece in the middle, ensuring that the workpiece remains stable and immobile throughout the machining process. When the side of the workpiece needs to be polished, the electric slide rails 8 on both sides first horizontally move the slide table 9 (in the X-axis direction) to a suitable position. Then, the first air cylinder 101 operates, and the piston rod of the first air cylinder 101 pushes the connecting block 102 to move inward (in the Y-axis direction). The connecting block 102 drives the rotating shaft 103 and the face milling cutter 104 to move towards the workpiece until the face milling cutter 104 simultaneously contacts both sides of the workpiece. At this time, the motor 105 inside the connecting block 102 starts to rotate. The motor 105 drives the rotating shaft 103 to rotate through the coupling, and then drives the face milling cutter 104 to contact the side of the workpiece. Cooperating with the electric slide rails 8 on both sides to drive the face milling cutter 104 on the slide table 9 to move synchronously, the horizontal milling operation on the side of the workpiece is completed. After the milling of one side of the workpiece is completed, the first air cylinder 101 operates again and drives the face milling cutter 104 to retract and reset. When the side of the workpiece needs to be milled on the other side, the driving motor 74 is enabled. The output shaft of the driving motor 74 drives the worm gear 73 to rotate through the worm 75. The rotation of the worm gear 73 is directly transmitted to the gear 72, causing the gear 72 to also rotate. The gear 72 meshes with the toothed ring 71 installed on the opposite end face of the mounting seat 5. Therefore, the rotation of the gear 72 drives the toothed ring 71 to rotate together. Since the slide bars 61 are evenly distributed on the outer side wall of the chuck 6, the slide bars 61 on the chuck 6 are embedded in the inner wall of the toothed ring 71 and are in sliding fit. When the toothed ring 71 rotates, it will drive the chuck 6 to rotate together, causing the workpiece between the upper and lower chucks 6 to rotate, thus facilitating the subsequent precise milling processing of each side of the workpiece. Moreover, the worm gear 73 and worm 75 structure can provide good self-locking performance, ensuring that the workpiece between the upper and lower chucks 6 will not easily rotate after the angle is adjusted, providing guarantee for the stable machining of the workpiece.

[0037] As Figure 1 , Figure 7 and Figure 8As shown, clamping mechanisms 12 are provided on both sides of the sliding tables 9. The clamping mechanism 12 includes a guiding sleeve 121, a sliding frame 122, clamping blocks 123, and an electric push rod two 124. The guiding sleeve 121 is fixedly arranged on one side of the two sliding tables 9 facing each other, and a rotating shaft one 103 slides through the guiding sleeve 121 internally.

[0038] A sliding frame 122 is slidably sleeved on the guiding sleeve 121. Two clamping blocks 123 are installed on one side of the left and right sliding frames 122 facing each other. The rotating shaft one 103 is located between the corresponding two clamping blocks 123. Two electric push rods two 124 are symmetrically and fixedly installed on the side wall of the sliding table 9. The push rods of the two electric push rods two 124 are respectively connected to the ends of the sliding frame 122.

[0039] The rotating shaft one 103 and the face milling cutter one 104 retract into the corresponding guiding sleeve 121 on the same side. The push rod of the electric push rod two 124 extends and drives the clamping blocks 123 on the sliding frame 122 to clamp the left and right sides of the workpiece, cooperating with the unlocking of the clamping of the workpiece by the upper and lower chucks 6, so as to facilitate the subsequent milling of the upper and lower end faces of the workpiece.

[0040] As Figure 3 、 Figure 5 and Figure 6 shown, a through hole communicating upward is provided in the middle of the chuck 6. End face milling mechanisms 11 are provided inside both the bottom frame 1 and the sliding frame 3. The end face milling mechanism 11 includes: a sliding plate 111, slidably installed inside the bottom frame 1 or the sliding frame 3; no less than two air cylinders two 112, symmetrically and fixedly installed on the sliding plate 111; a connecting block two 113, fixedly arranged on the piston rod of the air cylinder two 112. An installation inner cavity is also provided inside the connecting block two 113; a rotating shaft two 114, rotatably installed at the installation inner cavity of the connecting block two 113. The rotating shaft two 114 is located inside the through hole of the chuck 6. Face milling cutters two 115 are fixedly arranged on the opposite end faces of the upper and lower two rotating shafts two 114; a motor two 116, fixedly installed in the installation inner cavity of the connecting block two 113. The motor two 116 is connected to the rotating shaft two 114 through a coupling; an electric lead screw 117, arranged inside the bottom frame 1 or the sliding frame 3. The electric lead screw 117 is used to drive the corresponding sliding plate 111 to slide along the Y-axis direction, so that the air cylinders two 112, the connecting block two 113, the rotating shaft two 114, and the face milling cutters two 115 thereon on the sliding plate 111 move, enabling the workpiece clamped by the two clamping mechanisms 12 on both sides to be milled by the face milling cutters two 115 moving up and down on both sides, thereby milling the upper and lower end faces of the workpiece.

[0041] After the milling of the side surface of the workpiece is completed, the cylinder 101 drives the face milling cutter 104 to retract to the initial position. Then, by using the end face milling mechanism 11, the upper and lower end faces of the workpiece can be milled without removing the workpiece. First, the electric push rod 124 on the two side slides 9 is activated. The push rod of the electric push rod 124 extends and drives the sliding frame 122 to advance towards the side of the workpiece. Under the guidance of the guide sleeve 121, the clamping blocks 123 on the sliding frame 122 can clamp the workpiece from both sides. When the clamping blocks 123 on both sides firmly clamp the two sides of the workpiece, the push rod of the electric push rod 63 resets and drives the chuck 6 on the mounting frame 62 to release the clamping of the upper and lower end faces of the workpiece. Then, the cylinder 112 is activated. The piston rod of the cylinder 112 extends and promotes the connection block 113 to advance. The connection block 113 drives the face milling cutter 115 on the rotating shaft 114 to extend from the internal through hole of the chuck 6 until the upper and lower face milling cutters 115 respectively contact the upper and lower end faces of the workpiece. Then, the motor 116 is started and drives the rotating shaft 114 to rotate through the coupling, and cooperates with the electric lead screw 117 to drive the slide plate 111 to slide along the predetermined track, so that the cylinder 112, the connection block 113 and the rotating shaft 114 with the face milling cutter 115 on the slide plate 111 move. Finally, the upper and lower end faces of the workpiece are milled by the face milling cutter 115.

[0042] Embodiment 2: On the basis of Embodiment 1, as Figure 1 and Figure 9 shown, hydraulic pumps 13 are installed on the left and right side slides 9. Spray nozzles 131 are installed on both sides of the guide sleeve 121. The spray nozzles 131 face the face milling cutter 104. A plurality of spray nozzles 132 are circumferentially installed on the mounting base 5. The center of each spray nozzle 132 faces the chuck 6. The hydraulic pumps 13 are connected to each spray nozzle 131 and spray nozzle 132 through connecting pipes 133.

[0043] The hydraulic pumps 13 extract cutting fluid and sequentially introduce it into the spray nozzles 131 and spray nozzles 132 through the connecting pipes 133, so that the spray nozzles 131 and spray nozzles 132 spray cutting fluid onto the milling areas of the face milling cutter 104 and the face milling cutter 115, achieving the effects of cooling and cleaning the debris on the surface of the workpiece.

[0044] As Figure 1 、 Figure 9 and Figure 10 shown, collecting frames 14 are symmetrically and fixedly arranged on both sides of the mounting base 5 on the bottom frame 1. The front side of the collecting frame 14 is open. A baffle 141 is clamped at the opening of the collecting frame 14. The inner bottom surface of the collecting frame 14 is inclined. The bottom surface of the collecting frame 14 is inclined towards the opening where the baffle 141 is located.

[0045] When milling a workpiece, to ensure the machining quality and extend the tool life, cutting fluid is pumped by a hydraulic pump 13 and conveyed to a first nozzle 131 and a second nozzle 132 through a connecting pipe 133. The first nozzle 131 faces the area where the face milling cutter 104 is located, while the second nozzle 132 faces the chuck 6 on the mounting base 5. The first nozzle 131 and the second nozzle 132 spray the cutting fluid onto the part of the workpiece being milled, thus playing a role in cooling the workpiece and removing debris. For a high-speed rotating face milling cutter, timely cooling can significantly reduce the risk of thermal deformation and improve the machining quality of the workpiece. The debris washed by the cutting fluid will flow downward into the collection frames 14 on both sides of the bottom frame 1. The collection frames 14 are used to collect the washed debris and cutting fluid. Since the collection frames 14 are provided with inclined bottoms inside, this helps to guide the debris to the opening where the baffle 141 is located, facilitating subsequent cleaning and treatment, thereby improving the cleanliness of the device's machining environment and facilitating the recycling of waste materials.

[0046] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form. Any technical solutions obtained by means of equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
