Description

Technical Field

[0001] The present invention belongs to the technical field of metal workpiece processing equipment, and specifically refers to a linear chamfering device for metal workpiece processing. Background Art

[0002] A linear chamfering machine is a machine equipment used to perform linear chamfering on the edges of workpieces. It is widely used in fields such as metal processing, wood processing, and plastic processing. It uses a cutting edge to cut the edge of the workpiece to form a linear chamfer, which can effectively improve the surface quality and feel of the workpiece and avoid problems caused by edge burrs during the use of the workpiece.

[0003] Currently, a linear chamfering machine can adjust the size of the chamfer by adjusting the distance between two pallets. However, the angles of the pallets of the linear chamfering machine are fixed, and the two pallets are arranged at a fixed 90° angle. When the workpiece is placed between the two pallets, the angle is fixed, and only a 45-degree symmetric chamfer can be performed on the edge of the workpiece, and an asymmetric chamfer cannot be performed, which cannot meet diverse usage requirements. Summary of the Invention

[0004] In view of the above situation, to overcome the defects of the prior art, the present invention provides a linear chamfering device for metal workpiece processing, which at least partially solves the above problems.

[0005] The technical solution adopted by the present invention is as follows: The present invention provides a linear chamfering device for metal workpiece processing, including: A machine table, on which a tool for chamfering processing is provided on the tabletop; An installation frame, which is movably connected to the tabletop of the machine table and can reciprocally slide along its own length direction; A fixed pallet and a movable pallet arranged oppositely on the installation frame, and the fixed pallet and the movable pallet are located on both sides of the tool; Wherein, arc-shaped sliding rods and sliding sleeves are provided at both ends of the movable pallet. One end of the arc-shaped sliding rod is fixed on the movable pallet, and the other end is slidably inserted into the sliding sleeve, so that the movable pallet can swing along the sliding path of the arc-shaped sliding rod to adjust the included angle between the fixed pallet and the movable pallet; Movable angle irons are movably connected to both ends of the installation frame, and the movable angle irons are arranged to be able to slide along the distribution direction of the fixed pallet and the movable pallet, and the sliding sleeve is connected to the movable angle iron.

[0006] Further, adjusting screws are provided at both ends of the mounting frame. The mounting frame is provided with first threaded holes corresponding to the adjusting screws, and the opening direction of the first threaded holes is the same as the sliding direction of the movable angle iron. The adjusting screws are threadedly connected in the first threaded holes, and one end of the adjusting screw is rotatably connected to the movable angle iron. By rotating the adjusting screw, the movable angle iron can be pulled to move.

[0007] Further, locking bolts are provided on one side of the two movable angle irons located outside the mounting frame. The movable angle iron is provided with second threaded holes corresponding to the locking bolts. The locking bolts are threadedly connected in the second threaded holes, and one end of the locking bolt extends into the sliding sleeve. By tightening the locking bolt, the arc-shaped sliding rod can be locked.

[0008] Further, wear-resistant layers for reducing wear are electroplated on the outer side of the arc-shaped sliding rod and the inner side of the sliding sleeve.

[0009] Further, a clearance avoidance inclined surface for clearance avoidance is provided at the bottom of the movable supporting plate.

[0010] Further, two linear sliding rods are provided inside the mounting frame. The two linear sliding rods are arranged parallel to the length direction of the mounting frame. Sliding seats corresponding to the linear sliding rods are provided on the tabletop of the machine tool, and the linear sliding rods are slidably connected in the sliding seats.

[0011] Further, a limiting mechanism is provided on the tabletop of the machine tool. The mounting frame is provided with limiting holes corresponding to the limiting mechanism. When the limiting mechanism is connected to the limiting holes, the mounting frame can be locked. When the limiting mechanism is not connected to the limiting holes, the mounting frame can reciprocally slide along its own length direction.

[0012] Further, the limiting mechanism includes a supporting seat and a limiting pin. The limiting pin is located on one side of the mounting frame and corresponds to the limiting hole. The limiting pin is supported by the supporting seat and is slidably inserted into the supporting seat.

[0013] Further, a material blocking block for blocking materials is detachably connected to the movable supporting plate.

[0014] Further, electromagnetic chucks capable of generating magnetic fields are embedded and fixed on both the fixed supporting plate and the movable supporting plate, so that the electromagnetic chucks can magnetically fix magnetic workpieces.

[0015] The beneficial effects achieved by the present invention with the above structure are as follows: 1. By setting an arc-shaped slide bar and a sliding sleeve, since the arc-shaped slide bar is circular arc-shaped, the sliding path of the arc-shaped slide bar is circular arc-shaped. Correspondingly, the movable supporting plate connected to the arc-shaped slide bar can swing along the arc-shaped sliding path, changing the angle of the movable supporting plate, thereby adjusting the included angle between the fixed supporting plate and the movable supporting plate, so that the edge of the metal workpiece to be cut and the cutting surface of the tool can be adjusted to an asymmetric arrangement, realizing asymmetric chamfering.

[0016] 2. By arranging electromagnetic chucks capable of generating a magnetic field on the fixed supporting plate and the movable supporting plate, when chamfering magnetic workpieces with a small volume, the magnetic workpieces can be fixed by the magnetic attraction force generated by the electromagnetic chucks, improving the flexibility of equipment use.

They are used together with the embodiments of the present invention to explain the present invention, and do not constitute a limitation to the present invention. Detailed Embodiments

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0022] As Figure 1 shown, the present invention provides a linear chamfering device for metal workpiece processing, including a machine table 1, a tool 11, a mounting frame 2, a fixed support plate 3 and a movable support plate 4.

[0023] A driving unit is provided inside the machine table 1. The driving unit includes a motor and a transmission shaft. One end of the transmission shaft is connected to the output shaft of the motor, and the other end extends to the tabletop of the machine table 1 and is connected to the tool 11. The motor drives the tool 11 to rotate through the transmission shaft, so as to cut the metal workpiece.

[0024] Combined with Figure 1 and Figure 2 shown, the mounting frame 2 is movably connected to the tabletop of the machine table 1. Two linear slide bars 21 are provided inside the mounting frame 2. The two linear slide bars 21 are arranged parallel to the length direction of the mounting frame 2. Slide seats 22 corresponding to the linear slide bars 21 are provided on the tabletop of the machine table 1, and the linear slide bars 21 are slidably connected to the slide seats 22.

[0025] In this way, the mounting frame 2 can slide on the slide seats 22 through the linear slide bars 21, and since the linear slide bars 21 are arranged parallel to the length direction of the mounting frame 2, the mounting frame 2 can reciprocally slide along its own length direction.

[0026] Furthermore, the fixed support plate 3 and the movable support plate 4 are arranged oppositely on the mounting frame 2, and the fixed support plate 3 and the movable support plate 4 are located on both sides of the tool 11, and the metal workpiece is supported by the fixed support plate 3 and the movable support plate 4 (as Figure 5 shown).

[0027] Thus, when chamfering, place the metal workpiece to be chamfered on the fixed pallet 3 and the movable pallet 4, then push the metal workpiece to make it approach the cutter 11 along the fixed pallet 3 and the movable pallet 4 and pass through the cutter 11. The rotating cutter 11 cuts the edge of the metal workpiece to form a chamfer on the edge of the metal workpiece. Meanwhile, when chamfering a smaller metal workpiece, the metal workpiece placed on the fixed pallet 3 and the movable pallet 4 can be fixed, and then push the mounting frame 2 to make the metal workpiece approach the cutter 11 and pass through the cutter 11. The rotating cutter 11 cuts the edge of the metal workpiece.

[0028] In a specific embodiment, a stop block 41 for blocking materials is detachably connected to the movable pallet 4. When chamfering a smaller metal workpiece, first place the metal workpiece on the fixed pallet 3 and the movable pallet 4, then press the metal workpiece against the stop block 41, and the metal workpiece is located on the side of the stop block 41 close to the cutter 11, so that one side of the metal workpiece is fixed by the stop block 41. When pushing the mounting frame 2 to make the metal workpiece approach the cutter 11, the stop block 41 limits the metal workpiece from the rear and can push the metal workpiece to move.

[0029] It should be noted that when chamfering a longer workpiece, the stop block 41 can be removed, and the operator manually pushes the metal workpiece for chamfering.

[0030] Combined with Figure 1 and Figure 7 As shown, a limiting mechanism 8 is provided on the tabletop of the machine base 1, and a limiting hole 201 corresponding to the limiting mechanism 8 is provided on the mounting frame 2. When the limiting mechanism 8 is connected to the limiting hole 201, the mounting frame 2 can be locked. When the limiting mechanism 8 is not connected to the limiting hole 201, the mounting frame 2 can reciprocate along its own length direction.

[0031] In a specific embodiment, the limiting mechanism 8 includes a support base 81 and a limiting pin 82. The limiting pin 82 is located on one side of the mounting frame 2 and corresponds to the limiting hole 201. The limiting pin 82 is supported by the support base 81 and is slidably inserted into the support base 81.

[0032] Thus, when manually pushing the workpiece for chamfering, insert the limiting pin 82 on the support base 81 into the limiting hole 201 of the mounting frame 2. At this time, the mounting frame 2 is locked and cannot slide. When the operator pushes the workpiece for chamfering, it can be kept stable. When it is necessary to move the workpiece for chamfering by pushing the mounting frame 2, pull out the limiting pin 82 on the support base 81 outward to disengage the limiting pin 82 from the limiting hole 201. At this time, the mounting frame 2 can slide freely.

[0033] Combined with Figure 6As shown, electromagnetic chucks 7 capable of generating magnetic fields are fixedly embedded on both the fixed pallet 3 and the movable pallet 4, enabling the electromagnetic chucks 7 to magnetically fix magnetic workpieces.

[0034] In a specific embodiment, mounting grooves corresponding to the electromagnetic chucks 7 are respectively formed on the fixed pallet 3 and the movable pallet 4, and the electromagnetic chucks 7 are fixedly embedded in the mounting grooves. The magnetic adsorption surface of the electromagnetic chuck 7 on the fixed pallet 3 is flush with the supporting surface of the fixed pallet 3. Correspondingly, the magnetic adsorption surface of the electromagnetic chuck 7 on the movable pallet 4 is flush with the supporting surface of the movable pallet 4, maintaining the flatness of the supporting surfaces of the fixed pallet 3 and the movable pallet 4.

[0035] Thus, when chamfering a relatively small magnetic workpiece, if still relying on manual pressing of the workpiece by personnel, the risk is relatively high. At this time, the magnetic workpiece can be fixed by the magnetic attraction force generated by the electromagnetic chuck 7, improving the flexibility of equipment use.

[0036] Combined with Figure 2 、 Figure 3 and Figure 4 As shown, arc-shaped sliding rods 6 and sliding sleeves 61 are provided at both ends of the movable pallet 4. One end of the arc-shaped sliding rod 6 is fixed on the movable pallet 4, and the other end of the arc-shaped sliding rod 6 is slidably inserted into the sliding sleeve 61. The arc-shaped sliding rod 6 can slide along the sliding sleeve 61. Since the arc-shaped sliding rod 6 is arc-shaped, the sliding path of the arc-shaped sliding rod 6 is arc-shaped. Correspondingly, the movable pallet 4 connected to the arc-shaped sliding rod 6 can swing along the arc-shaped sliding path, that is, the movable pallet 4 rotates around the center of the arc-shaped sliding rod 6.

[0037] Thus, when chamfering a metal workpiece, by rotating and adjusting the movable pallet 4, the angle of the movable pallet 4 is changed, thereby adjusting the included angle between the fixed pallet 3 and the movable pallet 4 (as shown in Figure 5 ). At this time, after the metal workpiece leans on the movable pallet 4, the edge of the metal workpiece to be cut is asymmetrically arranged with the cutting surface of the tool 11, so that the workpiece can be chamfered asymmetrically, and according to the angle of the movable pallet 4, the specific angle sizes of the two angles of the asymmetric chamfering can be adjusted to meet diverse usage requirements.

[0038] Furthermore, movable angle irons 5 are movably connected to both ends of the mounting frame 2. The movable angle irons 5 are arranged to be able to slide along the distribution direction of the fixed pallet 3 and the movable pallet 4. The sliding sleeve 61 is connected to the movable angle iron 5, enabling the distance between the fixed pallet 3 and the movable pallet 4 to be adjusted.

[0039] Thus, by pushing the movable angle irons 5 at both ends, the sliding sleeve 61, the arc-shaped sliding rod 6, and the movable pallet 4 can be moved as a whole, thereby adjusting the distance between the movable pallet 4 and the fixed pallet 3 and changing the cutting amount of the edge of the metal workpiece.

[0040] Combined withFigure 1 and Figure 4 As shown, adjusting screw rods 51 are provided at both ends of the mounting frame 2. First threaded holes corresponding to the adjusting screw rods 51 are provided on the mounting frame 2, and the opening direction of the first threaded holes is the same as the sliding direction of the movable angle iron 5. The adjusting screw rods 51 are threadedly connected in the first threaded holes. When the adjusting screw rods 51 rotate, they can move along the opening direction of the first threaded holes. And when the adjusting screw rods 51 rotate forward or reverse, the adjusting screw rods 51 can reciprocate along the opening direction of the first threaded holes; One end of the adjusting screw rod 51 is rotatably connected to the movable angle iron 5. By rotating the adjusting screw rod 51, the adjusting screw rod 51 can pull the movable angle iron 5 to reciprocate.

[0041] In this way, by synchronously rotating the adjusting screw rods 51 at both ends, the movable angle irons 5 at both ends are pulled to move synchronously, and the movable support plate 4, the arc-shaped slide rod 6 and the sliding sleeve 61 connected to the movable angle iron 5 move synchronously. Furthermore, the movable support plate 4 is moved closer to or farther away from the fixed support plate 3 to adjust the distance between the fixed support plate 3 and the movable support plate 4. And during the movement of the movable support plate 4, it always remains parallel to the movable support plate 4.

[0042] Combined with Figure 2 and Figure 3 As shown, locking bolts 62 are provided on one side of the two movable angle irons 5 located outside the mounting frame 2. Second threaded holes corresponding to the locking bolts 62 are provided on the movable angle iron 5, and the second threaded holes penetrate through the movable angle iron 5. The locking bolts 62 are threadedly connected in the second threaded holes. When the locking bolts 62 rotate, they can move along the opening direction of the second threaded holes. And one end of the locking bolt 62 extends into the sliding sleeve 61. By rotating the locking bolt 62, the locking bolt 62 moves into the sliding sleeve 61 and abuts against the arc-shaped slide rod 6, so that the arc-shaped slide rod 6 is locked.

[0043] In this way, by rotating the locking bolt 62, the locking bolt 62 moves to the outside of the sliding sleeve 61. At this time, the locking bolt 62 is disengaged from the arc-shaped slide rod 6, and the arc-shaped slide rod 6 can slide normally, so as to adjust the angle of the movable support plate 4. After the adjustment is completed, by rotating the locking bolt 62, the locking bolt 62 moves into the sliding sleeve 61 and abuts against the arc-shaped slide rod 6, and the arc-shaped slide rod 6 can be locked, and further the movable support plate 4 is fixed and can stably support the workpiece.

[0044] In an alternative embodiment, wear-resistant layers for reducing wear are electroplated on the outer side of the arc-shaped slide rod 6 and the inner side of the sliding sleeve 61 to improve the wear resistance of the arc-shaped slide rod 6 and the sliding sleeve 61, and to avoid the generation of gaps between the arc-shaped slide rod 6 and the sliding sleeve 61 due to wear caused by sliding. Preferably, the wear-resistant layer is a chromium plating layer.

[0045] Since the movable platen 4 is located above the tool 11, when the movable platen 4 swings downward to adjust the angle, the bottom height of the movable platen 4 will decrease. To avoid the bottom of the movable platen 4 hitting and interfering with the tool 11, in combination with Figure 4 and Figure 5 As shown, a clearance inclined surface 401 for clearance is provided at the bottom of the movable platen 4 to increase the bottom space of the movable platen 4, thereby increasing the angle adjustment range of the movable platen 4.

[0046] The working principle of the present invention: When manually pushing the workpiece for chamfering, first insert the limit pin 82 into the limit hole 201 of the mounting frame 2 to lock the mounting frame 2, and then place the metal workpiece to be chamfered on the fixed platen 3 and the movable platen 4, and push the metal workpiece to make it approach the tool 11 along the fixed platen 3 and the movable platen 4 and pass through the tool 11. The rotating tool 11 cuts the edge of the metal workpiece to form a chamfer on the edge of the metal workpiece; At the same time, when chamfering a smaller metal workpiece, first place the metal workpiece on the fixed platen 3 and the movable platen 4, and then press the metal workpiece against the stop block 41, and the metal workpiece is located on the side of the stop block 41 close to the tool 11, so that one side of the metal workpiece is fixed by the stop block 41. When pushing the mounting frame 2 to make the metal workpiece approach the tool 11, the stop block 41 limits the metal workpiece from the rear and can push the metal workpiece to move. Finally, the rotating tool 11 cuts the edge of the metal workpiece; When chamfering the metal workpiece, by rotating to adjust the movable platen 4, the angle of the movable platen 4 is changed, thereby adjusting the included angle between the fixed platen 3 and the movable platen 4 (as Figure 5 shown). At this time, after the metal workpiece leans on the movable platen 4, the edge of the metal workpiece to be cut and the cutting surface of the tool 11 are asymmetrically arranged, so that the workpiece can be chamfered asymmetrically, and the specific angles of the two angles of the asymmetric chamfer can be adjusted according to the angle of the movable platen 4 to meet diverse usage requirements; By pushing the movable angle irons 5 at both ends, the sliding sleeve 61, the arc-shaped sliding rod 6 and the movable platen 4 can move as a whole, thereby adjusting the distance between the movable platen 4 and the fixed platen 3 and changing the cutting amount of the edge of the metal workpiece.

[0047] Combining the above embodiments: By providing the arc-shaped sliding rod 6 and the sliding sleeve 61, since the arc-shaped sliding rod 6 is arc-shaped, the sliding path of the arc-shaped sliding rod 6 is arc-shaped. Correspondingly, the movable platen 4 connected to the arc-shaped sliding rod 6 can swing along the arc-shaped sliding path, changing the angle of the movable platen 4, thereby adjusting the included angle between the fixed platen 3 and the movable platen 4, so that the edge of the metal workpiece to be cut and the cutting surface of the tool 11 can be adjusted to be asymmetrically arranged to achieve asymmetric chamfering.

[0048] By arranging electromagnetic chucks 7 capable of generating magnetic fields on the fixed pallet 3 and the movable pallet 4, when chamfering magnetic workpieces with relatively small volumes, the magnetic metal workpieces can be fixed by the magnetic attraction generated by the electromagnetic chucks 7, improving the flexibility of equipment use.

[0049] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.

[0050] The above describes the present invention and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments to this technical solution without creative efforts without departing from the gist of the present invention, they shall fall within the protection scope of the present invention.
