DETAILED DESCRIPTION

[0036] The present disclosure will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present disclosure, but not to limit the present disclosure.

[0037] In order to make the drawing simple, only the parts related to the disclosure are shown in the figures, which do not represent the actual structure of the product. In addition, in order to make the drawing simple and easy to understand, in some figures, only one of the parts with the same structure or function is shown, or only one of them is marked. In this paper, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0038] In this paper, it should be noted that, unless otherwise specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integral connection; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through intermediate medium, or the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present disclosure can be understood according to the specific circumstances.

[0039] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0040] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0041] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0042] like Figures 1-6 As shown, this invention discloses a fully automatic grooving grinder for machining milling cutters. A first moving table 1 and a second moving table 2 are located on the same moving path and can move via a servo motor driving a lead screw, guide rail, hydraulic cylinder, and other transmission components. The positions of the first moving table 1 and the second moving table 2 can be adjusted according to machining requirements to accommodate the clamping operations of milling cutters of different lengths. This improves the machine's adaptability to machining milling cutters of different sizes. Simultaneously, the precision of movement helps to accurately position the milling cutter during machining, ensuring machining accuracy.

[0043] The milling cutter clamp 5 can employ a mechanical clamping structure, such as a three-jaw chuck, a hydraulic clamp, or a clamp with a through hole 501, to clamp and fix one end of the milling cutter. Figure 2 and Figure 3 As shown, this solution uses a fixture with a through hole 501. The center 13 cooperates with the milling cutter clamp 5. The second moving table 2 moves closer to the milling cutter clamp 5 and together with the milling cutter clamp 5, it holds the two ends of the milling cutter, keeping it stable during the machining process, thereby improving the accuracy and quality of the milling cutter groove machining.

[0044] The grinding wheel 3 can be driven by a motor to rotate at high speed, such as... Figure 1As shown, the motor base is driven to move via a lead screw, guide rail, hydraulic cylinder, and other transmission components, thereby raising and lowering the grinding wheel 3. When the grinding wheel 3 descends to contact the milling cutter, it grinds the milling cutter. Simultaneously, the first moving table 1 and the second moving table 2 move, driving the milling cutter to move, thus machining the required groove shape.

[0045] The edge-cleaning grinding wheel 4 is also driven by a motor to rotate, and moves closer to or further away from the milling cutter using a moving mechanism (such as a linear motor, ball screw slide, or hydraulic cylinder). When it moves to the position of the milling cutter, it grinds the circumference of the cutter to remove machining allowance and improve the surface quality of the cutter's circumference. Specifically, during edge cleaning, the edge-cleaning grinding wheel 4 feeds radially (with an angle), adjusting the position of the peripheral teeth relative to the circumference of the milling cutter to machine the primary and secondary clearance angles. This allows for edge cleaning and grinding operations after groove machining to be performed on the same equipment, avoiding errors caused by process transfer in traditional processes, improving production efficiency and the overall quality of the milling cutter. Furthermore, the grinding position and grinding intensity can be precisely adjusted according to the different diameters of the milling cutter and machining requirements.

[0046] In some examples, the through hole 501 on the milling cutter holder 5 is designed to fit the size of the milling cutter end. When clamping the milling cutter, one end of the milling cutter is inserted into the through hole 501. The portion of the holder surrounding the through hole 501 is preferably elastic. In the initial state, the diameter of the through hole 501 is smaller than the diameter of one end of the milling cutter. When the milling cutter is inserted into the through hole 501, the circumferential portion of the through hole 501 is opened, and the elastic force clamps the milling cutter inserted into the through hole 501, achieving a stable installation of the milling cutter on the milling cutter holder 5. This ensures that during machining, the milling cutter can rotate accurately around its own axis without affecting machining accuracy due to wobbling or displacement.

[0047] In some examples, the tapered design of tip 13 allows its tip to precisely abut against the end of the milling cutter. Suitable for milling cutters with shaft holes, the tapered tip inserts into the shaft hole, improving the efficiency and accuracy of milling cutter clamping.

[0048] In some examples, the inner cavity 101 of the second moving stage 2 provides space for the push rod 6 to move. When the milling cutter needs to be replaced, the push rod 6 moves within the inner cavity 101 of the second moving stage 2 in a direction coaxial with the through hole 501 under the action of a drive device (such as a cylinder, hydraulic cylinder, or motor screw mechanism). Since the diameter of the push rod 6 is smaller than the diameter of the through hole 501, it can smoothly extend into the through hole 501 of the milling cutter holder 5. After the push rod 6 contacts the end of the milling cutter in the through hole 501, it continues to advance forward, using a pushing force to push the milling cutter out of the through hole 501 of the milling cutter holder 5, thus separating the milling cutter from the milling cutter holder 5, making it convenient for the operator to remove the milling cutter and perform subsequent replacements or other operations. When the milling cutter is being clamped, the push rod 6 moves in the opposite direction, moving out of the through hole 501, making room for the clamping of the milling cutter and improving the convenience of milling cutter replacement.

[0049] Previously, changing milling cutters might have required operators to manually disassemble the cutter holder 5 or use other cumbersome methods to remove the cutter. Now, the automatic pushing operation of the push rod 6 simplifies the cutter changing process, shortens the changeover time, and improves production efficiency. Furthermore, because the cutter is automatically pushed by a mechanical structure, the cutter disengagement is more stable and reliable compared to manual operation, reducing the risk of cutter or holder damage due to improper human operation. In addition, this design facilitates the automation of the milling process, making it easy to integrate with other automated machining processes and enhancing the overall automation level of the production line.

[0050] In some examples, when the worm 8 rotates on the first moving table 1 driven by a motor or other drive device, the rotational motion of the worm 8 is transmitted to the worm wheel 7 through the interaction between the teeth due to the meshing between the worm 8 and the worm wheel 7. The worm wheel 7 is mounted on the milling cutter holder 5, thereby driving the milling cutter holder 5 to rotate on the side wall of the first moving table 1. The worm wheel 7 and worm 8 transmission has good self-locking performance. When the worm 8 stops rotating, the worm wheel 7 will remain stationary due to its own friction and the mutual constraint between the teeth, ensuring that the milling cutter holder 5 remains stable at the set angular position. This prevents the milling cutter holder 5 from rotating unexpectedly due to external interference or other factors during the machining process, ensuring the stability and reliability of the machining process.

[0051] In some examples, both the grooving wheel 3 and the edge-cleaning wheel 4 are arranged at an axial angle relative to the through hole 501, creating an angle between their grinding surfaces and the milling cutter's axis. During machining, when the milling cutter holder 5 rotates the milling cutter while the grooving wheel 3 descends to contact the milling cutter for grooving, the angled wheels allow for more efficient machining of the milling cutter's grooves and circumference. By adjusting the wheel's tilt angle, the shape of the milling cutter's grooves, such as the groove's taper and bottom fillet radius, can be flexibly controlled to meet the diverse design requirements of different types of milling cutters. When grinding the milling cutter's circumference, the angled wheels better adapt to the milling cutter's curved surface, improving grinding uniformity and surface quality, and reducing surface defects caused by uneven grinding.

[0052] In some examples, the feed plate 901 of the feed rack 9 is arranged at an angle along its height. Utilizing gravity, the milling cutters placed on the feed plate 901 can slowly slide down its inclined surface under their own weight. The drop port 902 is located below the feed plate 901. When the sliding milling cutter reaches the drop port 902, it will fall from it. This structural design enables automatic unloading of milling cutters, eliminating the need for manual handling of each cutter to the machining position and significantly improving pre-machining loading efficiency.

[0053] The feeding component 10 moves on the material rack 9 via a transmission mechanism such as a guide rail, lead screw, push rod 6, or hydraulic cylinder. When it is necessary to receive a milling cutter falling from the drop port 902, the feeding component 10 moves under the action of a drive device (such as a motor or cylinder) to below the drop port 902, aligning its receiving groove 1001 with the drop port 902, and the milling cutter falls into the receiving groove 1001 to complete the receiving action. Subsequently, the feeding component 10 moves again, transporting the receiving groove 1001 containing the milling cutter to the position between the milling cutter clamp 5 and the center point 13, facilitating the accurate transfer of the milling cutter between the milling cutter clamp 5 and the center point 13 for clamping and machining.

[0054] In some examples, the swing member 1004 is oscillatingly disposed at one end of the plate 1002 having the first arc-shaped groove 1003 by means of connection such as a pin or hinge. When the feeding component 10 moves to receive the milling cutter below the drop port 902, the swing component 1004 is in its initial position under the action of the elastic component 1006. At this time, the second arc groove 1005 and the first arc groove 1003 combine to form the receiving groove 1001. After the milling cutter falls into the receiving groove 1001, the feeding component 10 moves to the position between the milling cutter clamp 5 and the tip 13 under the action of the driving device (such as a motor, cylinder, etc.). The first moving stage 1 and the second moving stage 2 move closer to each other, so that the milling cutter chuck and the tip 13 jointly clamp the milling cutter located on the receiving groove 1001. After the clamping is stable, the feeding component 10 moves to reset under the action of the driving device (such as a motor, cylinder, etc.). During the reset process, the swing component 1004 will come into contact with the fixed milling cutter. Since the milling cutter has been fixed and stable, and the swing component 1004 will swing under the thrust of the milling cutter, it will make room for the overall movement of the feeding component 10 and avoid interference and jamming.

[0055] In some examples, the receiving component 11 is arranged at an angle and its position is moved by a moving mechanism such as a guide rail, lead screw, or hydraulic cylinder. When the milling cutter finishes machining and needs to be removed from between the milling cutter holder 5 and the center point 13, the receiving component 11 begins to move under the action of a drive device (such as a motor or hydraulic cylinder). The drive device transmits power to the receiving component 11 through a transmission assembly, causing it to move along the guide rail to the target position. When it has moved into position, the higher end of the receiving component 11 is located below the space between the milling cutter holder 5 and the center point 13. At this time, the operator releases the finished milling cutter from the milling cutter holder 5 and the center point 13, and uses the push rod 6 to remove the milling cutter from the milling cutter holder 5. Under its own weight, the milling cutter slides down the inclined surface of the receiving component 11. When it is necessary to transfer the received milling cutter to the next process or storage location, the receiving component 11 moves again, and its higher end is no longer located below the space between the milling cutter holder 5 and the center point 13, facilitating subsequent operations.

[0056] In some examples, the unloading conveyor belt 12 is driven by a motor, which drives the conveyor belt to move in a circular motion via a transmission device (such as a belt or chain). Since the conveyor belt is a conventional technology, it has been simplified in the accompanying drawings of this solution. The conveyor belt is positioned on one side of the lower end of the receiving component 11. When the milling cutter slides off the inclined surface of the receiving component 11, it falls directly onto the circulating conveyor belt. The conveyor belt operates continuously, transporting the received milling cutters to designated locations, such as the loading area for subsequent processing steps or the finished product storage area. The motor speed can be adjusted by the control system, thereby controlling the conveyor belt's movement speed to adapt to different production rhythms and milling cutter receiving frequencies. The unloading conveyor belt 12 achieves automated transportation of the milling cutters after receiving them, further reducing manual intervention and improving production efficiency. It works in conjunction with the receiving component 11 to form a continuous unloading process, preventing the accumulation of milling cutters after processing and maintaining a clean and orderly processing area. By adjusting the conveyor belt speed, the transportation rhythm of the milling cutters can be flexibly controlled to better match the pace of the entire processing production line. Moreover, conveyor belts have a simple structure, relatively low cost, are easy to maintain and replace, and can operate stably for a long time, ensuring the continuity of production.
