Description

Technical Field

[0001] The present application relates to the technical field of machining machine tools, and in particular to a slot milling cutter structure and a machining device. Background Art

[0002] In mechanical processing, some surfaces that need to be sealed or docked often require annular grooves to be opened on the workpiece to install sealing rings or guide docking. The existing method of opening annular grooves on the workpiece is generally to cut the workpiece with a slot milling cutter. When facing the processing of annular grooves coaxial with some shaft holes, the annular groove milling cutter is generally used to quickly complete the cutting after the tool is aligned. However, when the existing annular groove milling cutter is used, the distance between the two edges of the annular groove milling cutter cannot be effectively adjusted, which makes it inconvenient to effectively select a suitable annular groove milling cutter according to the existing annular groove diameter or size. The applicability of the annular groove milling cutter is poor, and when there are annular grooves of different diameters on the workpiece that need to be processed, the existing processing device usually needs to replace the annular groove milling cutter, and the work efficiency is low. Some annular milling cutters that can adjust the distance between the two edges are more troublesome to adjust. It is necessary to remove the screws on the tool slide, move the slide, and then tighten the screws. This method is not only troublesome but also requires ensuring the distance between the two edges of the annular groove cutter and the spindle, thereby affecting the later processing efficiency.

[0003] Therefore, the present invention provides a slot milling cutter structure and a processing device. Summary of the invention

Detailed implementation manners

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application.

[0035] As Figures 1 - 2 shown, a slot milling cutter structure proposed in an embodiment of the present application includes a mounting shaft 1 and a positioning ring 2 constructed on the outer peripheral side of the mounting shaft 1. A plurality of guiding ridges 3 are constructed at one end of the mounting shaft 1. The structure further includes two mounting seats 4 symmetrically and slidably mounted on the plurality of guiding ridges 3. An installation groove 25 is formed in the mounting seat 4 for installing a blade. An adjusting member 5 acting on the two mounting seats 4 is mounted on the mounting shaft 1. By means of the adjusting member 5, the two mounting seats 4 are driven to move. A pressing sleeve 26 is rotatably sleeved between the mounting shaft 1 away from the mounting seat 4 and the positioning ring 2. The pressing sleeve 26 is the position fixed by the fixture. After the pressing sleeve 26 is fixed, the subsequent rotation of the mounting shaft 1 will not drive the fixture to rotate. That is to say, when in use, first install the blade in the installation groove 25. After the blade is installed in the installation groove 25, the blade is installed by means of bolt installation. Here, the structure of the mounting seat 4 is similar to that of the existing double-edge groove milling cutter. The blade is provided with holes for bolts to pass through, and threaded holes are provided in the installation groove 25. After the blade is installed, the two mounting seats 4 can be driven to move through the adjusting member 5, so as to adjust the distance between the two blades. Furthermore, the distance between the two blades can be quickly adjusted, and the distance between the two mounting seats 4 can be adjusted according to the diameter of the annular groove. When facing the need to machine annular structures with different diameters, the number of tool replacements is effectively reduced, and the processing efficiency is indirectly improved.

[0036] As Figure 2 shown, in some embodiments, the interior of the mounting shaft 1 is hollow. The adjusting member 5 includes an actuating rod 501 horizontally and slidably inserted into one end of the mounting shaft 1 away from the mounting seat 4. One end of the actuating rod 501 is located outside, and the other end is located inside the mounting shaft 1 and symmetrically hinged with two linkage rods 502. The two linkage rods 502 are respectively hinged on the two mounting seats 4. A plugging groove 503 is formed at the end of the actuating rod 501 located outside. Limiting protrusions 504 are symmetrically constructed in the plugging groove 503. That is to say, after the mounting shaft 1 is fixed, at this time, by moving the actuating rod 501, when the actuating rod 501 moves, it will drive the linkage rods 502 hinged thereon to move. Since the two linkage rods 502 are respectively hinged on the two mounting seats 4, when the actuating rod 501 moves, the two mounting seats 4 will approach or move away from each other through the linkage rods 502, so as to ensure that when the two mounting seats 4 move, the distances of the two mounting seats 4 from the axis of the mounting shaft 1 are the same, ensuring the accuracy during subsequent cutting and preventing deviations from occurring when cutting the annular groove due to the inconsistent distances of the two mounting seats 4 from the axis of the mounting shaft 1.

[0037] As Figure 1 and Figure 2As shown, in some embodiments, at one end of the mounting shaft 1 where the guiding rib 3 is provided, through slots 6 are symmetrically provided. On both mounting seats 4, connecting blocks 7 are respectively constructed to pass through the two through slots 6. On both connecting blocks 7, strip-shaped long plates 8 are constructed. Two linkage rods 502 are respectively hinged on the two strip-shaped long plates 8. A return spring is installed between the two strip-shaped long plates 8. On the connecting blocks 7, retaining pieces 9 with one end located outside are constructed. The retaining pieces 9 are used to block the through slots 6. Due to the design of the return spring, the two mounting seats 4 are in a state of being away from each other under normal conditions. When the actuating rod 501 is pulled by an external driving force, the movement of the actuating rod 501 will drive the two mounting seats 4 to approach each other. After the cutting is completed, when the actuating rod 501 is released, the two mounting seats 4 will move away from each other and return to their positions through the return spring. The design of the retaining piece 9 plays a protective role. When the two mounting seats 4 move, the retaining piece 9 has sufficient length to block the through slots 6, effectively preventing iron filings from passing through the through slots 6 and entering the mounting shaft 1 during the cutting process, which is inconvenient to clean.

[0038] As Figures 1 - 11 shown, the embodiment of the present application also discloses a processing device, which includes the above-mentioned slot milling cutter structure, and further includes:

[0039] A base 24, on which a horizontally arranged electric slide rail 10 is installed. A moving frame 11 is horizontally slidably installed on the electric slide rail 10. A cross slide rail 12 is horizontally slidably installed on the moving frame 11. The cross slide rail 12 is a conventional structure and is composed of two electric linear slides. A connecting plate 13 is installed on the cross slide rail 12. A telescopic shaft 14 is horizontally and rotatably installed on the connecting plate 13. Specifically, the telescopic shaft 14 is a cylinder installed on the connecting plate 13, and a slide bar in a rectangular shape is slidably inserted into the free end of the cylinder. Thus, when the cylinder rotates, the slide bar will also rotate accordingly. A motor for driving the telescopic shaft 14 to rotate is installed on the connecting plate 13. An installation frame 19 is installed on the connecting plate 13;

[0040] A clamping mechanism 15, installed on the installation frame 19, which is used to clamp the mounting shaft 1. When the clamping mechanism 15 clamps the mounting shaft 1, the positioning ring 2 fits on the clamping mechanism 15;

[0041] A connecting mechanism 16, including a docking block 1601 installed at the free end of the telescopic shaft 14. Two clamping plates 1602 are symmetrically and slidably installed on the docking block 1601. Clamping grooves 1604 are opened on the opposite sides of the two clamping plates 1602 for the limiting convex block 504 to be inserted. An elastic telescopic rod 1603 is installed between the two clamping plates 1602;

[0042] The adjusting component 17 is installed on the mounting bracket 19 and acts on the telescopic shaft 14. It is used to drive the moving end of the telescopic shaft 14 to move. When in use, moving the mounting shaft 1 will make the positioning ring 2 fit against one side of the clamping mechanism 15. During this process, press the two clamping plates 1602 so that the clamping plates 1602 are located in the insertion slot 503. When the positioning ring 2 fits against the clamping mechanism 15, at this time, the clamping groove 1604 is opposite to the limiting convex block 504. Then release the two limiting convex blocks 504, and the elastic telescopic rod 1603 will make the limiting convex block 504 inserted into the clamping groove 1604, thereby completing the connection between the actuating rod 501 and the docking block 1601. And the elastic telescopic rod 1603 can effectively prevent the limiting convex block 504 from disengaging from the clamping groove 1604. At this time, fix the pressing sleeve 26 through the clamping mechanism 15. Subsequently, the adjusting component 17 can drive the moving end of the telescopic shaft 14 to move. The moving end of the telescopic shaft 14 moves, which indirectly drives the actuating rod 501 to move. When the actuating rod 501 moves, it drives the two mounting seats 4 to approach or move away from each other. After adjustment, when the telescopic shaft 14 rotates, it will drive the actuating rod 501 to rotate. Because the actuating rod 501 is slidably inserted on the mounting shaft 1 and the pressing sleeve 26 is fixed by the clamping mechanism 15 at this time, the mounting shaft 1 will rotate around the pressing sleeve 26, thereby making the two mounting seats 4 on the mounting shaft 1 rotate to realize the cutting of the workpiece. When cutting annular grooves with other diameters, at this time, drive the telescopic shaft 14 to move through the adjusting component 17, thereby indirectly driving the movement of the actuating rod 501 to complete the rapid adjustment of the two mounting seats 4. This not only ensures the distance between the two mounting seats 4 and the mounting shaft 1, but also can effectively reduce the number of tool changes and further improve the later processing efficiency.

[0043] As Figure 1 and Figure 5 shown, in some embodiments, the clamping mechanism 15 includes a plurality of pressing plates 1502 slidably mounted on the mounting bracket 19 in a circular array. A ring-shaped bracket 1501 coaxial with the telescopic shaft 14 is rotatably mounted on the mounting bracket 19. A plurality of hinge rods 1503 are hinged on the ring-shaped bracket 1501. The free ends of the plurality of hinge rods 1503 are respectively hinged on the plurality of pressing plates 1502. A driving component 18 for driving the ring-shaped bracket 1501 to rotate is mounted on the mounting bracket 19. That is to say, when the driving component 18 drives the ring-shaped bracket 1501 to rotate, it will drive the plurality of hinge rods 1503 to move. When the hinge rods 1503 move, because one end of the hinge rod 1503 is hinged on the pressing plate 1502, when the ring-shaped bracket 1501 rotates, the plurality of hinge rods 1503 will drive the free ends of the plurality of pressing plates 1502 to approach or move away from each other, which not only ensures coaxiality, but also the pressing sleeve 26 is pressed by the plurality of pressing plates 1502, increasing the pressing area and thus ensuring the pressing strength.

[0044] AsFigure 7 and Figure 8 As shown in Figure 8 , in some embodiments, the driving assembly 18 includes a hinge block 1801 hinged to the mounting bracket 19. A rotating lead screw 1802 is rotatably mounted on the hinge block 1801. An installation frame 1803 is constructed on the annular frame 1501. A threaded block 1804 is slidably mounted on the installation frame 1803. The threaded block 1804 is threadedly sleeved on the rotating lead screw 1802. That is to say, when the rotating lead screw 1802 is rotated, the rotation of the rotating lead screw 1802 will drive the threaded block 1804 to move on the rotating lead screw 1802. When the threaded block 1804 moves, the threaded block 1804 will move on the installation frame 1803. As the threaded block 1804 moves, the annular frame 1501 will also adaptively rotate, thereby realizing the movement of the plurality of pressing plates 1502. Because the screw thread fit has self-locking property, when the annular frame 1501 moves, it can effectively prevent the annular frame 1501 from accidentally rotating when the telescopic shaft 14 rotates.

[0045] As Figure 6 and Figure 8 As shown in Figure 8 , in some embodiments, the adjusting assembly 17 includes a moving block 1701 horizontally slidably mounted on the mounting bracket 19. A connecting ring 1702 is constructed on the moving block 1701. The connecting ring 1702 is rotatably sleeved on the docking block 1601. An installation cylinder 1703 is mounted on the mounting bracket 19. A connecting rod 1704 is slidably mounted on the installation cylinder 1703. A return spring 1705 is mounted between the connecting rod 1704 and the installation cylinder 1703. A transmission member 20 is mounted on the mounting bracket 19 to drive the moving block 1701 to move or cancel the movement. That is to say, when the transmission member 20 drives the moving block 1701 to move, the movement of the moving block 1701 will drive the connecting ring 1702 connected thereto to move. Because the connecting ring 1702 is rotatably sleeved on the docking block 1601, the docking block 1601 moves horizontally at this time, thereby indirectly driving the movement of the actuating rod 501. When it is necessary to disassemble the mounting shaft 1 from the plurality of pressing plates 1502, at this time, the movement of the moving block 1701 is cancelled by the transmission member 20. At this time, the moving block 1701 will quickly reset due to the reset of the return spring 1705. At this time, the two mounting seats 4 will quickly move away from each other. Then rotate the rotating lead screw 1802 to make the plurality of pressing plates 1502 move away from each other. Then press the two clamping plates 1602 to make the clamping groove 1604 disengage from the limiting protrusion 504, and then the mounting shaft 1 can be directly pulled out.

[0046] As Figure 8 and Figure 11As shown, in some embodiments, the transmission member 20 includes two rotating rods 2001 rotatably mounted on the mounting frame 19, and a transmission wheel 2002 is rotatably mounted on the rotating rod 2001. A transmission belt 2003 is installed between the two transmission wheels 2002 for transmission, and the moving block 1701 is connected to the top horizontal section of the transmission belt 2003. A rotary drum 2004 is installed on one of the rotating rods 2001, and a limiting member 21 for canceling the limit or limiting the rotation of the rotary drum 2004 is installed on the mounting frame 19. That is to say, when it is necessary to adjust the movement of the actuator 501, one of the rotating rods 2001 can be rotated by rotating the rotary drum 2004. When the rotating rod 2001 rotates, it mobilizes the transmission wheel 2002 to rotate, and then the two transmission wheels 2002 are rotated through the transmission belt 2003. The transmission wheels 2002 rotate synchronously, and the transmission belt 2003 will also move at this time. The transmission belt 2003 will indirectly drive the moving block 1701 connected to it to move during the movement, so that the moving block 1701 moves and drives the movement of the actuator 501. After the movement, the rotation of the rotary cylinder 2004 can be limited by the limiting member 21. In this way, each time the holding sleeve 26 is removed from the multiple clamping plates 1502, the return spring 1705 can make the moving block 1701 move and reset to the initial position. In this way, each time the distance between the two mounting seats 4 is measured, it is only necessary to measure the moving distance of the moving block 1701 to deduce the distance between the two mounting seats 4, thereby ensuring that the starting point of each measurement is consistent, which is convenient for the staff to control the distance between the two mounting seats 4.

[0047] like Figure 2 , Figure 8 , Figure 9 and Figure 11 As shown, in some embodiments, the limiting member 21 includes a connecting cylinder 2101 installed on the mounting frame 19, a wedge-shaped plug plate 2102 is horizontally slidably installed on the connecting cylinder 2101, a plurality of wedge-shaped slots 2103 are provided in a circular array on the outer peripheral side of the rotating cylinder 2004, which are used for inserting the wedge-shaped plug plate 2102, a connecting spring 2104 is installed between the wedge-shaped plug plate 2102 and the connecting cylinder 2101, and a pulling frame 2105 located outside is constructed on one side of the wedge-shaped plug plate 2102. When the mounting shaft 1 is installed, the moving block 1701 is located at the initial position at this time, and then the rotating cylinder 2004 is rotated to make the wedge-shaped plug plate 2103 move. The slot 2103 contacts the inclined surface of the wedge-shaped insert plate 2102, and when the moving block 1701 moves to the left as shown in FIG. 9, the transmission belt 2003 is driven to move, so that the plane of the wedge-shaped slot 2103 contacts the plane of the wedge-shaped insert plate 2102, thereby effectively avoiding the resetting of the moving block 1701 due to the elastic deformation characteristics of the return spring 1705, which is more convenient to use. When the actuator 501 needs to be returned to its original position, it is only necessary to pull the wedge-shaped insert plate 2102 to disengage it from the wedge-shaped slot 2103, so that the moving block 1701 moves and returns to its initial position due to the return spring 1705.

[0048] As Figure 8 and Figure 9 shown, in some embodiments, a scale 22 is mounted on the mounting bracket 19, and a pointer 23 is mounted on the moving block 1701. Specifically, when the moving block 1701 moves to the initial position, the pointer 23 at this time knows the zero position of the scale 22. In this way, when the staff rotates the rotating cylinder 2004 subsequently, they can more intuitively see the distance that the moving block 1701 moves, and then calculate the position of the mounting seat 4. Of course, the ratio of the moving distance of the moving block 1701 to the ratio of the moving distance of the mounting seat 4 can also be directly calculated and written on the scale 22, so that the scale of the scale 22 directly corresponds to the distance between the two blades, thereby further facilitating the use of the staff.
