Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application. ​

[0038] Please refer to Figures 1 to 11 The application provides a technical scheme: a multi-direction cutting device for metal casting, comprising:

[0039] The support base 1 is movably connected with a cutting disc support 2 on the left side of the top of the support base 1, and the right side of the support base 1 is provided with a movable groove 3, and the inside of the movable groove 3 is transversely and slidably connected with a support plate 4. It should be noted that a disc cutting knife is movably installed in the inside of the cutting disc support.

[0040] Further comprising:

[0041] The support base 1 is movably connected with a cutting disc support 2 on the left side of the top of the support base 1, and the right side of the support base 1 is provided with a movable groove 3, and the inside of the movable groove 3 is transversely and slidably connected with a support plate 4.

It should be noted that a disc cutting knife is movably installed in the inside of the cutting disc support.

[0043] In this embodiment, as shown in Figures 1 to 11 The orientation switching mechanism 5 comprises a transmission motor 501, the transmission motor 501 is fixedly connected to the right side of the inner wall of the movable groove 3, the rotating end of the transmission motor 501 is fixedly connected with a transmission screw rod 502, the left end of the transmission screw rod 502 is rotatably connected to the left side of the inner wall of the movable groove 3, the surface of the transmission screw rod 502 is threadedly connected with a transmission block 503, the bottom of the support plate 4 is fixedly connected with a synchronous block 504 matched with the transmission block 503, and a reset spring 505 is movably connected between the right side of the support plate 4 and the right side of the inner wall of the movable groove 3. It should be noted that when the transmission motor 501 rotates with the transmission screw rod 502, the transmission block 503 moves on the surface of the transmission screw rod 502 and moves the synchronous block 504 from left to right, and the reset spring 505 can reset the synchronous block 504 and the support plate 4 from right to left.

[0044] The top vertical rod of the support plate 4 is fixedly connected with a plug rod 506, the surface of the plug rod 506 movably sleeves a taper sleeve 507, the bottom of the taper sleeve 507 is lapped on the bottom of the support plate 4, four L-shaped guide grooves 508 are equidistantly and circumferentially provided on the upper part of the inner wall of the taper sleeve 507, the four L-shaped guide grooves 508 are connected in a loop, four telescopic guide rods 509 are equidistantly and circumferentially fixedly connected to the upper part of the plug rod 506, and the four telescopic guide rods 509 are respectively and slidably connected in the four L-shaped guide grooves 508.

[0045] The top of the taper sleeve 507 is fixedly connected with a casting clamp 510, and the right side of the inner wall of the movable groove 3 is fixedly connected with a U-shaped push plate 511 matched with the lower part of the taper sleeve 507. It should be noted that when the support plate 4 with the taper sleeve 507 moves to the position of the U-shaped push plate 511, the side wall of the U-shaped push plate 511 is in contact with the tapered surface of the lower part of the taper sleeve 507, at this time, the taper sleeve 507 can rise on the surface of the inserting rod 506, when the taper sleeve 507 moves upward, the telescopic guide rod 509 on the inserting rod 506 slides along the inclined groove position of the L-shaped guide groove 508, so that the taper sleeve 507 can rotate 90 degrees with the casting clamp 510; when the taper sleeve 507 moves left with the support plate 4 and is out of contact with the U-shaped push plate 511, under the action of gravity, the taper sleeve 507 moves downward on the surface of the inserting rod 506, at this time, the telescopic guide rod 509 slides along the vertical groove position of the L-shaped guide groove 508, in this process, the taper sleeve 507 does not continue to rotate and is limited to the top position of the support plate 4; the casting clamp 510 can switch the clamping surface of the rectangular metal casting to avoid being clamped in the cutting surface position, the casting clamp 510 adopts the existing electric clamp, which will not be described in detail here.

[0046] In the embodiment, as shown in Figures 1 to 11 The two sides of the inner wall of the movable groove 3 are fixedly connected with slide rods, the support plate 4 is slidingly connected between the two slide rods, and the reset spring 505 is movably sleeved on the right side of the slide rod.

[0047] Four positioning grooves are equidistantly formed on the top of the support plate 4 along the circumference, four positioning blocks are equidistantly fixedly connected to the bottom of the taper sleeve 507 along the circumference, and the four positioning blocks are movably inserted into the four positioning grooves respectively. It should be noted that the top of the positioning groove is provided with a tapered surface, which facilitates the insertion of the positioning block, when the taper sleeve 507 moves downward and falls on the top surface of the support plate 4, through the matched insertion of the positioning groove and the positioning block, the rotation of the taper sleeve 507 can be effectively limited, and under the action of the L-shaped guide groove 508, when the taper sleeve 507 rises and the positioning block is out of insertion with the positioning groove, the taper sleeve 507 can rotate.

[0048] The inner wall of the L-shaped guide groove 508 is arranged in a stepped manner, and the distance between the bottom of the U-shaped push plate 511 and the bottom surface of the taper sleeve 507 is the same as the height of the L-shaped guide groove 508. It should be noted that when the U-shaped push plate 511 moves from the upper part of the inclined surface of the taper sleeve 507 to the lower part of the inclined surface, the telescopic guide rod 509 moves from the top to the bottom of the L-shaped guide groove 508; through the stepped L-shaped guide groove 508, the telescopic guide rod 509 is prevented from rotating reversely in the L-shaped guide groove 508, so that the L-shaped guide groove 508 and the telescopic guide rod 509 can only rotate the taper sleeve 507 90 degrees in one direction during the matched sliding process.

[0049] In the embodiment, as shown in Figures 1 to 11As shown, the bottom of the transmission block 503 is slidingly connected to the inner bottom surface of the movable groove 3, both sides of the transmission block 503 are provided with a transmission groove, a wedge-shaped block is vertically slidingly connected inside the transmission groove, the upper part of the wedge-shaped block penetrates the transmission groove and is lapped with the side wall of the synchronous block 504, and an extrusion spring is fixedly connected between the bottom of the wedge-shaped block and the inner bottom surface of the transmission groove. It should be noted that: through the wedge-shaped block, when the transmission block 503 moves from left to right, the synchronous block 504 and the supporting plate 4 can be moved to the right, when the transmission block 503 moves from right to left with the wedge-shaped block, the inclined surface of the wedge-shaped block is pressed by the bottom of the synchronous block 504 and can be retracted inside the transmission groove, at this time the transmission block 503 cannot move to the left with the synchronous block 504, ensuring that the transmission block 503 can move to the left with the wedge-shaped block to the limit position, so that the wedge-shaped block can pass through the bottom position of the synchronous block 504, avoiding interference.

[0050] The side wall of the wedge-shaped block is provided with an inclined groove, the inner wall of the transmission groove is symmetrically slidingly connected with a transmission rod, the surface of the transmission rod is fixedly connected with a pin shaft matched with the inclined groove, and the right side of the inner bottom surface of the movable groove 3 is fixedly connected with an unlocking pad matched with the transmission rod. It should be noted that: when the supporting plate 4 moves to the right with the taper sleeve 507 and cooperates with the U-shaped push plate 511 to slide to the limit state, the transmission rod on the right side of the transmission block 503 contacts with the unlocking pad, so that the pin shaft on the transmission rod cooperates with the inclined groove on the side wall of the wedge-shaped block to slide, and then the wedge-shaped block moves downward and releases the limiting of the synchronous block 504, so that the return spring 505 can move leftward with the supporting plate 4 to reset.

[0051] In this embodiment, as shown in the figure, Figures 1 to 11 The transmission adjusting mechanism 6 includes a rectangular groove 601, the rectangular groove 601 is provided in the top of the supporting seat 1, the inside of the rectangular groove 601 is slidingly connected with an L-shaped push plate 602, the left side of the supporting seat 1 is internally provided with an adjusting groove 603 matched with the rectangular groove 601, the inner wall of the adjusting groove 603 is fixedly connected with an electric telescopic rod 604, the movable end of the electric telescopic rod 604 is hinged with an adjusting plate 605, the top of the adjusting plate 605 is provided with a waist-shaped groove 606, the bottom of the L-shaped push plate 602 is fixedly connected with an adjusting pin 607, and the adjusting pin 607 is slidingly connected inside the waist-shaped groove 606. It should be noted that: the bottom of the adjusting plate 605 is provided with a hinge groove, the movable end of the electric telescopic rod 604 is fixedly connected with a hinge block, and the hinge block is slidingly connected inside the hinge groove. When the electric telescopic rod 604 is extended or retracted, the hinge block cooperates with the hinge groove to slide, so that the adjusting plate 605 is deflected in the adjusting groove 603 with the adjusting pin 607 as the fulcrum.

[0052] The left side of the top of the support base 1 is provided with a longitudinal groove 608, and the inside of the longitudinal groove 608 is slidably connected with an adjusting seat 609. The bottom of the adjusting seat 609 is fixedly connected with a connecting shaft 610, the connecting shaft 610 penetrates through the longitudinal groove 608 and is slidably connected in the inside of the waist-shaped groove 606, and the top of the adjusting seat 609 is fixedly connected with the bottom of the cutting disc support 2. It should be noted that, when the adjusting plate 605 is deflected in the inside of the adjusting groove 603, the adjusting groove 603 is matched with the connecting shaft 610 to slide, the adjusting seat 609 and the cutting disc support 2 are moved along the track of the longitudinal groove 608 by the connecting shaft 610, and the disc cutting knife on the cutting disc support 2 is used for cutting the side wall of the rectangular metal casting.

[0053] In the embodiment, as shown in the figure, Figures 1 to 11 The two sides of the inner wall of the rectangular groove 601 are provided with sliding grooves, the two sides of the L-shaped push plate 602 are fixedly connected with sliding blocks, the two sliding blocks are slidably connected in the two sliding grooves respectively, and the side wall of the sliding block is fixedly connected with the inner wall of the sliding groove. It should be noted that, when the rectangular metal casting on the casting clamp 510 removes the pressure on the L-shaped push plate 602, the restoring spring can move the L-shaped push plate 602 back to the original position.

[0054] The two sides of the middle part of the L-shaped push plate 602 are fixedly connected with pneumatic limiting rods matched with the rectangular groove 601. It should be noted that, when the rectangular metal casting presses the L-shaped push plate 602 to move, the pneumatic limiting rods are started to press against the side wall of the rectangular groove 601, the position of the L-shaped push plate 602 is limited, and the stability of the adjusting pin 607 at the bottom of the L-shaped push plate 602 in the adjusting groove 603 is ensured.

[0055] In the embodiment, as shown in the figure, Figures 1 to 11 The bottom of the support plate 4 is provided with a limiting hole, and the left side of the inner bottom of the movable groove 3 is fixedly connected with an electric limiting rod matched with the limiting hole. It should be noted that, when the support plate 4 moves to the left to the limit position, the electric limiting rod is started to extend and is inserted in the inside of the limiting hole, the position of the support plate 4 is locked, and the stability of the support plate 4 in the cutting process of the rectangular metal casting is ensured.

[0056] In the embodiment, as shown in the figure, Figures 1 to 11 A method for using a multi-directional cutting device for metal casting, comprising the following steps:

[0057] S1, in use, the adjusting plate 605 is rotated in the adjusting groove 603 by the electric telescopic rod 604 with the adjusting pin 607 as a fulcrum. When the adjusting plate 605 is in a horizontal state, the adjusting pin 607 at the bottom of the L-shaped push plate 602 can slide to the right to the limit position in the adjusting groove 603, and then the electric telescopic rod 604 is closed.

[0058] S2, then the rectangular metal casting is clamped and positioned by the casting clamp 510, the transmission motor 501 is started to rotate with the transmission lead screw 502, the transmission block 503 on the transmission lead screw 502 pulls the synchronous block 504 and the supporting plate 4 to move to the right of the movable groove 3, the supporting plate 4 synchronously moves to the right with the taper sleeve 507 and the rectangular metal casting on the casting clamp 510, when the taper sleeve 507 moves to the position of the U-shaped push plate 511 on the inner wall right of the movable groove 3, the U-shaped push plate 511 cooperates with the taper surface at the lower part of the taper sleeve 507, so that the taper sleeve 507 rises on the surface of the inserting rod 506, at this time the telescopic guide rod 509 on the inserting rod 506 cooperates with the L-shaped guide groove 508 on the inner wall of the taper sleeve 507 to slide, so that the taper sleeve 507 rotates ninety degrees on the top of the supporting plate 4 with the casting clamp 510 and the rectangular metal casting, and the cutting direction of the rectangular metal casting is automatically changed.

[0059] S3, while the transmission block 503 continuously moves to the right, the transmission rod contacts the unlocking pad block on the inner wall right of the movable groove 3, so that the wedge-shaped block on the top of the transmission block 503 releases the restriction of the synchronous block 504, at this time the return spring 505 moves the supporting plate 4 and the taper sleeve 507 to the left for resetting, when the U-shaped push plate 511 releases the contact with the taper sleeve 507, under the action of gravity, the taper sleeve 507 moves downward on the surface of the inserting rod 506 for resetting and is limited on the top surface position of the supporting plate 4.

[0060] S4, during the left movement of the supporting plate 4, the rectangular metal casting after the orientation switching will press against the surface of the L-shaped push plate 602 on the top of the supporting seat 1, so that the L-shaped push plate 602 moves the adjusting pin 607 on the top of the adjusting plate 605, and according to the different pressing distances of the L-shaped push plate 602, the position of the adjusting pin 607 moving in the adjusting groove 603 on the top of the adjusting plate 605 is also different, at this time the pivot position of the next deflection of the adjusting plate 605 is automatically adjusted, then the electric telescopic rod 604 is started to extend and retract with the adjusting pin 607 as the pivot after the adjusting position is adjusted in the adjusting groove 603, so that the left end of the adjusting plate 605 pulls the adjusting seat 609 and the cutting disc support 2 to slide along the trajectory of the vertical groove 608, and the left side position of the rectangular metal casting is cut by the disc cutting knife on the cutting disc support 2.

[0061] S5. In summary, when the long side of the rectangular metal casting moves to the position of the cutting disc support 2, the L-shaped push plate 602 moves a short distance under pressure. At this time, the fulcrum of the adjusting plate 605 is close to the position of the electric telescopic rod 604. When the electric telescopic rod 604 extends and retracts, causing the adjusting plate 605 to deflect, the left end of the adjusting plate 605 deflects significantly. When the short side of the rectangular metal casting moves to the position of the cutting disc support 2, the distance from the short side of the rectangular metal casting to the center of the casting fixture 510 is long. At this time, the distance the rectangular metal casting moves against the L-shaped push plate 602 increases, causing the fulcrum of the adjusting plate 605 to shift to the left. When the electric push rod extends and retracts, causing the adjusting plate 605 to deflect, the left end of the adjusting plate 605 deflects less. Thus, the deflection of the adjusting plate 605 can be automatically adjusted according to the different side lengths of the rectangular metal parts, and the moving distance of the disc cutting tool for cutting can be automatically adjusted, improving processing efficiency.
