Description

Technical Field

[0001] The invention relates to the technical field of metal parts processing, and in particular to a milling device for processing hydraulic parts. Background Art

[0002] Hydraulic parts, also known as hydraulic components or hydraulic assemblies, are the basic units that make up the 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 are subject to high pressure when working and must ensure that the liquid medium does not leak. Therefore, there are strict requirements for the processing of hydraulic parts, especially the milling process.

The above-mentioned milling processing device uses the transfer mechanism to achieve rapid tool replacement, thereby improving the milling processing efficiency of a single surface, but there are certain limitations when processing workpieces that require multi-faceted processing. Since only one surface of the workpiece can be processed at a time, for complex workpieces or workpieces with multiple processing surfaces, after completing the processing of one surface, the workpiece needs to be disassembled from the device, repositioned and clamped to process other surfaces, which not only increases the operation time, but also introduces potential position errors each time it is re-clamped.

DETAILED DESCRIPTION

[0028] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

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

[0030] Embodiment 1: A milling device for processing hydraulic parts, such as Figure 1-Figure 5As shown, 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 installed 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 installed 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 also includes: a mounting seat 5, which is provided as an upper and lower two and is slidably installed on the opposite end surfaces of the bottom frame 1 and the sliding frame 3 along the X-axis direction, and a through opening is provided in the middle of the mounting seat 5; a chuck 6 is slidably sleeved in the through opening of each mounting seat 5, and is used to clamp the upper and lower sides of the workpiece; a mounting frame 62 is slidably installed inside each mounting seat 5, and the mounting The frame 62 and the corresponding chuck 6 rotate in cooperation; the electric push rod 63 is provided with more than two and is located inside the mounting seat 5, the push rod of the electric push rod 63 is connected to the corresponding mounting frame 62, and is used to drive the mounting frame 62 to move along the Z-axis direction; the driving mechanism 7 is arranged on the mounting seat 5 and is used to drive the chuck 6 to rotate, so that the workpiece clamped between the upper and lower chucks 6 can be rotated and adjusted; the electric slide rail 8 is provided with two and is symmetrically fixed on the left and right sides of the bottom frame 1; the slide table 9 is slidably installed on the electric slide rail 8 along the X-axis direction, and the slide table 9 is provided with a side milling mechanism 10 for milling the side of the workpiece.

[0031] The hydraulic cylinder 4 drives the sliding frame 3 to rise and fall vertically, so that the mounting seat 5 on the bottom frame 1 and the sliding frame 3 clamps the inserted workpiece through the chuck 6, and then the electric slide rail 8 drives the side milling mechanism 10 on both sides to perform side milling on the workpiece, and the driving mechanism 7 synchronously drives the workpiece clamped between the chucks 6 to rotate, so as to perform milling processing on different sides of the workpiece.

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

[0033] The driving motor 74 drives the worm wheel 73 to rotate through the meshing of the worm 75, so that the worm wheel 73 synchronously drives the gear 72 to rotate, and finally the gear 72 meshes to drive the gear ring 71 and the corresponding chuck 6 to rotate, so that the milling angle of the workpiece between the chucks 6 can be accurately adjusted, and through the self-locking property of the worm wheel 73 and the worm 75, the chuck 6 with the adjusted angle can stably clamp the workpiece.

[0034] like Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the side milling mechanism 10 includes: a cylinder 101, fixedly mounted on the slide 9; a connecting block 102, fixedly connected to the piston rod of the cylinder 101, and an installation cavity is provided inside the connecting block 102; a rotating shaft 103, penetrating and rotatably mounted on the slide 9, the rotating shaft 103 and the connecting block 102 are rotatably matched, and a face milling cutter 104 is fixedly provided on the left and right end surfaces of the rotating shaft 103 facing each other; a motor 105, fixedly mounted in the installation cavity of the connecting block 102, and the motor 105 is connected to the rotating shaft 103 through a coupling.

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

[0036] Before using the present milling device to mill a workpiece, 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 activating the hydraulic cylinder 4. When the piston rod of the hydraulic cylinder 4 is extended or retracted, 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 mounting seat 5 between the bottom frame 1 and the sliding frame 3 to ensure that it can adapt to workpieces of different heights or thicknesses, and then put the workpiece into a suitable milling position between the upper and lower chucks 6, and then activate the electric push rod 1 63. As the push rod of the electric push rod 1 63 drives the chuck 6 on the mounting frame 62 to be lifted up in the corresponding mounting seat 5 opening, the upper and lower chucks 6 are in close contact and firmly clamp the workpiece in the middle, ensuring that the workpiece remains stable and motionless during the entire processing process. When it is necessary to grind the side of the workpiece, the electric slide rails 8 on both sides first move the slide table 9 horizontally (in the X-axis direction) to a suitable position, and then the cylinder 101 is actuated. The piston rod of 101 pushes the connecting block 102 to move inward (in the Y-axis direction), and the connecting block 102 drives the rotating shaft 103 and the face milling cutter 104 to move toward the workpiece until the face milling cutter 104 synchronously contacts the two side surfaces of the workpiece. At this time, the motor 105 located inside the connecting block 102 starts to rotate, and the motor 105 drives the rotating shaft 103 to rotate through the coupling, thereby driving the face milling cutter 104 to contact the side of the workpiece, and cooperates with the electric slide rails 8 on both sides to drive the face milling cutter 104 on the slide 9 to move synchronously, thereby completing the horizontal milling operation on the side of the workpiece. After completing the milling of the side of the workpiece, the cylinder 101 moves again and drives the face milling cutter 104 to reset and retract. When it is necessary to change the face of the workpiece side, the drive motor 74 is enabled, and the output shaft of the drive motor 74 drives the worm wheel 73 to rotate through the worm 75. The rotation of the worm wheel 73 will be directly transmitted to the gear 72, so that the gear 72 also rotates. The gear 72 meshes with the toothed ring 71 installed on the opposite end face of the mounting seat 5, so the rotation of the gear 72 will drive the toothed ring 71 to rotate together. Since the sliding strips 61 are evenly distributed on the outer wall of the chuck 6, the sliding strips 61 on the chuck 6 are embedded in the inner wall of the toothed ring 71 and slide together. When the toothed ring 71 rotates, it will rotate with the chuck 6, causing the workpiece between the upper and lower chucks 6 to rotate, thereby facilitating the subsequent precise milling of each side of the workpiece, and the worm wheel 73 and worm 75 structure can provide good self-locking performance, so that the workpiece between the upper and lower chucks 6 will not rotate easily after the angle is adjusted, thereby providing a guarantee for the stable processing of the workpiece.

[0037] like Figure 1 , Figure 7 and Figure 8As shown, the slides 9 on both sides are provided with a clamping mechanism 12, the clamping mechanism 12 includes a guide sleeve 121, a slide frame 122, a clamping block 123 and an electric push rod 124. The guide sleeve 121 is fixedly arranged on the opposite side of the two slides 9, and a rotating shaft 103 is slidably penetrated inside the guide sleeve 121;

[0038] A sliding frame 122 is slidably mounted on the guide sleeve 121, and two clamping blocks 123 are installed on the opposite sides of the sliding frame 122 on the left and right sides. The rotating shaft 103 is located between the two corresponding clamping blocks 123, and two electric push rods 124 are symmetrically fixedly installed on the side wall of the slide 9, and the push rods of the two electric push rods 124 are respectively connected to the ends of the sliding frame 122.

[0039] The rotating shaft 103 and the face milling cutter 104 retract to the corresponding guide sleeve 121 on the same side, the push rod of the electric push rod 124 extends and drives the clamping block 123 on the sliding frame 122 to clamp the left and right sides of the workpiece, and cooperates with the upper and lower chucks 6 to unlock the clamping of the workpiece to facilitate the subsequent milling of the upper and lower end surfaces of the workpiece.

[0040] like Figure 3 , Figure 5 and Figure 6 As shown, the middle of the chuck 6 is provided with an upward through opening, and the bottom frame 1 and the sliding frame 3 are both provided with an end face milling mechanism 11, and the end face milling mechanism 11 includes: a slide plate 111, which is slidably mounted inside the bottom frame 1 or the sliding frame 3; a second cylinder 112, which is provided with no less than two and symmetrically fixedly mounted on the slide plate 111; a second connecting block 113, which is fixedly mounted on the piston rod of the second cylinder 112, and a mounting inner cavity is also opened inside the second connecting block 113; a second rotating shaft 114, which is rotatably mounted at the mounting inner cavity of the second connecting block 113, and the second rotating shaft 114 is located inside the through opening of the chuck 6, and the upper and lower ends of the second rotating shaft 114 are opposite to each other. A face milling cutter 115 is fixedly provided on the surface; a motor 116 is fixedly installed in the mounting inner cavity of the connecting block 113, and the motor 116 is connected to the rotating shaft 114 through a coupling; an electric screw 117 is arranged inside the bottom frame 1 or the sliding frame 3, and the electric screw 117 is used to drive the corresponding slide 111 to slide along the Y-axis direction, so that the cylinder 112, the connecting block 113 and the rotating shaft 114 on the slide 111 and the face milling cutter 115 thereon are moved, so that the workpiece clamped by the clamping mechanisms 12 on both sides can be milled by the face milling cutter 115 moving on the upper and lower sides, thereby milling the upper and lower end surfaces of the workpiece.

[0041] After completing the milling of the side of the workpiece, the cylinder 101 drives the face milling cutter 104 to retract to the initial position, and then the end milling mechanism 11 is used to mill the upper and lower end faces of the workpiece without removing the workpiece. First, the electric push rods 124 on the slides 9 on both sides are activated, and the push rods of the electric push rods 124 extend and drive the sliding frame 122 to advance toward 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 are firmly clamped on both sides of the workpiece, the push rods of the electric push rods 163 are reset and drive the chuck 6 on the mounting frame 62 to release the clamping of the upper and lower end faces of the workpiece. The workpiece is held, and the cylinder 112 is activated again. The piston rod of the cylinder 112 extends out and causes the connecting block 113 to advance. The connecting block 113 drives the face milling cutter 115 on the rotating shaft 114 to extend out from the internal opening of the chuck 6 until the upper and lower face milling cutters 115 respectively contact the upper and lower end surfaces 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 screw 117 to drive the slide plate 111 to slide along the predetermined track, so that the cylinder 112, the connecting block 113 and the rotating shaft 114 with the face milling cutter 115 on the slide plate 111 move, and finally the upper and lower end surfaces of the workpiece are milled by the face milling cutter 115.

[0042] Embodiment 2: Based on embodiment 1, Figure 1 and Fig. 9 As shown, 6. A hydraulic pump 13 is installed on the slide 9 on the left and right sides, and a nozzle 131 is installed on both sides of the guide sleeve 121, and the nozzle 131 faces the face milling cutter 104. A plurality of nozzles 132 are circumferentially installed on the mounting seat 5, and the center of each nozzle 132 faces the chuck 6. The hydraulic pump 13 connects each nozzle 131 and nozzle 2 132 through a connecting pipe 133.

[0043] The hydraulic pump 13 draws cutting fluid and passes it into the nozzle 1 131 and the nozzle 2 132 in sequence through the connecting pipe 133, so that the cutting fluid is sprayed from the nozzle 1 131 and the nozzle 2 132 onto the milling area of ​​the face milling cutter 104 and the face milling cutter 2 115, so as to achieve the effect of cooling and cleaning the debris on the surface of the workpiece.

[0044] like Figure 1 , Fig. 9 and Fig.10 As shown, the mounting seat 5 on the bottom frame 1 is symmetrically fixed with a collection frame 14 on both sides, the front side of the collection frame 14 is an opening, and a baffle 141 is clamped at the opening of the collection frame 14. The inside of the collection frame 14 is an inclined bottom surface, and the bottom surface of the collection frame 14 is inclined toward the opening where the baffle 141 is located.

[0045] When milling a workpiece, in order to ensure the processing quality and extend the life of the tool, cutting fluid is extracted by a hydraulic pump 13 and transported to nozzle 1 131 and nozzle 2 132 through a connecting pipe 133. Nozzle 1 131 faces the area where the face milling cutter 104 is located, and nozzle 2 132 faces the chuck 6 on the mounting seat 5, so that nozzle 1 131 and nozzle 2 132 spray cutting fluid to the part of the workpiece being milled, thereby 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 quality of workpiece processing. The debris cleaned by the cutting fluid will flow downward into the collecting frames 14 on both sides of the bottom frame 1. The collecting frames 14 are used to collect the cleaned debris and cutting fluid. Since the collecting frame 14 is provided with an inclined bottom surface, this helps to guide the debris to the opening where the baffle 141 is located, which is convenient for subsequent cleaning and processing, thereby improving the cleanliness of the processing environment of the device and facilitating the recycling of waste materials.
