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.

DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0018] like Figure 1-Figure 2As 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, one end of the mounting shaft 1 is constructed with a plurality of guide ridges 3, and also includes two mounting seats 4 symmetrically slidably mounted on the plurality of guide ridges 3, the mounting seats 4 are provided with mounting grooves 25, the mounting grooves 25 are used to install blades, an adjusting member 5 acting on the two mounting seats 4 is installed on the mounting shaft 1, the two mounting seats 4 are driven to move by the adjusting member 5, the mounting shaft 1 is away from the mounting seat 4 and the positioning ring 2 is provided with a pressing sleeve 26, the pressing sleeve 26 is the position fixed by the clamp, after the pressing sleeve 26 is fixed, the subsequent rotation of the mounting shaft 1 will not drive the clamp to rotate, that is, That is to say, when in use, the blade is first installed in the mounting groove 25. After the blade is installed in the mounting groove 25, the blade is installed by bolt installation. The mounting seat 4 here is similar to the structure of the existing double-edged groove milling cutter. A hole is opened on the blade for the bolt to pass through, and a threaded hole is opened in the mounting groove 25. After the blade is installed, the two mounting seats 4 can be driven to move by the adjusting member 5, thereby adjusting the distance between the two blades, thereby realizing the rapid adjustment of the distance between the two blades. The distance between the two mounting seats 4 can be adjusted according to the diameter of the annular groove. When faced with annular structures that need to have different diameters, the number of times the tool is replaced is effectively reduced, thereby indirectly improving the processing efficiency.

[0019] like Figure 2 As shown, in some embodiments, the interior of the mounting shaft 1 is hollow, and the adjusting member 5 includes an actuator rod 501 that is horizontally slidably inserted at one end of the mounting shaft 1 away from the mounting seat 4. One end of the actuator rod 501 is located outside, and the other end is located inside the mounting shaft 1 and is symmetrically hinged with two connecting rods 502. The two connecting rods 502 are respectively hinged on the two mounting seats 4. The end of the actuator rod 501 located outside is provided with a plug-in slot 503, and a limited position protrusion 504 is symmetrically constructed in the plug-in slot 503. That is to say, when the mounting shaft 1 is fixed, the actuator rod 501 can be adjusted by moving the actuator rod 501. Rod 501, when the execution rod 501 moves, it will drive the connecting rod 502 hinged thereon to move. Because the two connecting rods 502 are respectively hinged on the two mounting seats 4, when the execution rod 501 moves, the connecting rod 502 will make the two mounting seats 4 approach or move away from each other, thereby ensuring that when the two mounting seats 4 move, the distance between the two mounting seats 4 and the axis of the mounting shaft 1 is consistent, ensuring the accuracy of subsequent cutting, and preventing deviations in cutting the annular groove due to inconsistent distances between the two mounting seats 4 and the axis of the mounting shaft 1.

[0020] like Figure 1 and Figure 2As shown, in some embodiments, the installation shaft 1 is provided with a guide convex strip 3 at one end thereof, and a through slide groove 6 is symmetrically provided. The two installation seats 4 are each configured with a connecting block 7 that passes through the two through slide grooves 6 respectively. The two connecting blocks 7 are each configured with a strip long plate 8. The two linkage rods 502 are respectively hinged on the two strip long plates 8. A return spring is installed between the two strip long plates 8. The connecting blocks 7 are each configured with a baffle 9 with one end located outside. The baffle 9 is used to block the through slide groove 6. The design of the return spring ensures that the two installation seats 4 are in a state of being kept in a state of being ... The two mounting seats 4 are kept in a state of being away from each other. When the actuator rod 501 is pulled by an external driving force, the movement of the actuator rod 501 will drive the two mounting seats 4 to approach each other. After the cutting is completed, the actuator rod 501 is released and the return spring will make the two mounting seats 4 move away from each other and return to their original positions. The design of the baffle 9 plays a protective role. When the two mounting seats 4 move, the baffle 9 has a sufficient length to block the through-slot 6, thereby effectively preventing iron chips from passing through the through-slot 6 and entering the mounting shaft 1 during the cutting process, which is inconvenient to clean.

[0021] like Figure 1-Figure 11 As shown, the embodiment of the present application further discloses a processing device, which includes the above-mentioned slot milling cutter structure, and also includes: A base 24 is provided on the base 24, a horizontal electric slide rail 10 is provided on the electric slide rail 10, a mobile frame 11 is provided on the mobile frame 11 for horizontal sliding, a cross slide rail 12 is provided on the mobile frame 11 for horizontal sliding, the cross slide rail 12 is an existing structure, and is composed of two electric linear slides, a connecting plate 13 is provided on the cross slide rail 12, a telescopic shaft 14 is provided on the connecting plate 13 for horizontal and rotatable installation, specifically, the telescopic shaft 14 is a cylinder provided on the connecting plate 13, and a rectangular slide bar is provided on the free end of the cylinder for sliding insertion, so that when the cylinder rotates, the slide bar will also rotate, a motor for driving the telescopic shaft 14 to rotate is provided on the connecting plate 13, and a mounting frame 19 is provided on the connecting plate 13; The clamping mechanism 15 is mounted on the mounting frame 19 and is used to clamp the mounting shaft 1. When the clamping mechanism 15 clamps the mounting shaft 1, the positioning ring 2 is attached to the clamping mechanism 15. The connecting mechanism 16 comprises a docking block 1601 mounted on the free end of the telescopic shaft 14, two clamping plates 1602 are symmetrically slidably mounted on the docking block 1601, and the two clamping plates 1602 are provided with clamping grooves 1604 on the opposite sides thereof for inserting the limiting protrusion 504, and an elastic telescopic rod 1603 is installed between the two clamping plates 1602; The adjusting component 17 is installed on the mounting frame 19 and acts on the telescopic shaft 14. It is used to drive the movable end of the telescopic shaft 14 to move. When in use, moving the mounting shaft 1 will make the positioning ring 2 fit with one side of the clamping mechanism 15. In this process, the two clamping plates 1602 are pressed so that the clamping plates 1602 are located in the insertion groove 503. When the positioning ring 2 fits with the clamping mechanism 15, the clamping groove 1604 is opposite to the limiting protrusion 504. At this time, the two limiting protrusions 504 are released, and the limiting protrusion 504 is inserted into the clamping groove 1604 through the elastic telescopic rod 1603, thereby completing the connection between the actuator rod 501 and the docking block 1601, and the elastic telescopic rod 1603 can effectively prevent the limiting protrusion 504 from being separated from the clamping groove 1604. At this time, the clamping sleeve 26 is fixed by the clamping mechanism 15, and then the movable end of the telescopic shaft 14 can be driven by the adjusting component 17. The movable end moves, and the movable end of the telescopic shaft 14 moves, thereby indirectly driving the actuator rod 501 to move. When the actuator rod 501 moves, it drives the two mounting seats 4 to move closer or farther away from each other. After adjustment, the telescopic shaft 14 will drive the actuator rod 501 to rotate when it rotates. Because the actuator rod 501 is slidably inserted on the mounting shaft 1 and the holding sleeve 26 is fixed by the clamping mechanism 15 at this time, the mounting shaft 1 at this time will rotate with the holding sleeve 26, thereby causing the two mounting seats 4 on the mounting shaft 1 to rotate to achieve cutting of the workpiece. When it is necessary to cut annular grooves of other diameters, the telescopic shaft 14 is driven to move by the adjusting component 17 at this time, thereby indirectly driving the movement of the actuator rod 501 to complete the rapid adjustment of the two mounting seats 4, which 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, further improving the later processing efficiency.

[0022] like Figure 1 and Figure 5 As shown, in some embodiments, the clamping mechanism 15 includes a plurality of pressing plates 1502 slidably mounted in a circular array on a mounting frame 19, a ring frame 1501 coaxial with the telescopic shaft 14 is rotatably mounted on the mounting frame 19, a plurality of hinged rods 1503 are hinged on the ring frame 1501, and the free ends of the plurality of hinged rods 1503 are respectively hinged on the plurality of pressing plates 1502, and a driving assembly 18 for driving the ring frame 1501 to rotate is installed on the mounting frame 19, that is, by driving When component 18 drives the annular frame 1501 to rotate, it will drive multiple hinged rods 1503 to move. When the hinged rod 1503 moves, because one end of the hinged rod 1503 is hinged on the clamping plate 1502, when the annular frame 1501 rotates, the free ends of the multiple clamping plates 1502 will be driven to approach or move away from each other through the multiple hinged rods 1503, which not only ensures coaxiality, but also the holding sleeve 26 is clamped by the multiple clamping plates 1502, thereby increasing the holding area and ensuring the clamping strength.

[0023] like Figure 7 and Figure 8 As shown, in some embodiments, the driving assembly 18 includes an articulated block 1801 hinged on the mounting frame 19, a rotating screw 1802 is rotatably mounted on the articulated block 1801, a mounting frame 1803 is constructed on the annular frame 1501, a threaded block 1804 is slidably mounted on the mounting frame 1803, and the threaded block 1804 is threadedly sleeved on the rotating screw 1802, that is, when the rotating screw 1802 is rotated, the rotating screw 1802 will rotate because the driving threaded block 1804 moves on the rotating screw 1802, and the threaded block 1804 will move on the mounting frame 1803 when the threaded block 1804 moves. As the threaded block 1804 moves, the annular frame 1501 will also rotate adaptively, thereby realizing the movement of multiple clamping plates 1502. Because the threaded fit is self-locking, the annular frame 1501 can effectively prevent the annular frame 1501 from rotating accidentally when the telescopic shaft 14 rotates after it moves.

[0024] like Figure 6 and Figure 8 As shown, in some embodiments, the adjustment assembly 17 includes a moving block 1701 horizontally slidably mounted on the mounting frame 19, a connecting ring 1702 is constructed on the moving block 1701, and the connecting ring 1702 is rotatably mounted on the docking block 1601, a mounting cylinder 1703 is mounted on the mounting frame 19, a connecting rod 1704 is slidably mounted on the mounting cylinder 1703, a return spring 1705 is installed between the connecting rod 1704 and the mounting cylinder 1703, and a transmission member 20 is installed on the mounting frame 19, and the moving block 1701 is driven to move or cancel the movement through the transmission member 20, that is, when the transmission member 20 drives the moving block 1701 to move, the movement of the moving block 1701 will drive the connecting ring 170 connected thereto. 2 movement, because the connecting ring 1702 is rotatably mounted on the docking block 1601, the docking block 1601 moves horizontally at this time, thereby indirectly driving the movement of the actuator 501. When the installation shaft 1 needs to be disassembled from the multiple clamping plates 1502, the movement of the moving block 1701 is cancelled through the transmission member 20. At this time, the moving block 1701 will be 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, and then the rotating screw 1802 is rotated to make the multiple clamping plates 1502 move away from each other, and then the two clamping plates 1602 are pressed to make the clamping groove 1604 disengage from the limiting protrusion 504, so that the installation shaft 1 can be directly withdrawn.

[0025] like Figure 8 and Fig.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.

[0026] like Figure 2 , Figure 8 , Fig. 9 and Fig.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.

[0027] like Figure 8 and Fig. 9 As shown, in some embodiments, a scale 22 is installed on the mounting frame 19, and a pointer 23 is installed 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, so that when the staff rotates the drum 2004 later, they can more intuitively see the distance moved by the moving block 1701, and then calculate the position of the mounting seat 4. Of course, the moving distance ratio of the moving block 1701 and the moving distance ratio of the mounting seat 4 can also be directly converted and written directly 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.
