[0031] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.
[0032] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements 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 the utility model.
[0033] Please see Figures 1-7 As shown, this utility model is a multi-station adjustable die-cutting plate positioning fixture, including an upper template 1, two stations 2 are symmetrically opened inside the upper template 1, two guide members 3 are symmetrically installed in each of the two stations 2, and a clamping plate 5 is also installed in the station 2.
[0034] The guide member 3 is equipped with a fastener 4, which includes two annular rubber pads 401. The two annular rubber pads 401 are distributed at the upper and lower ends of the guide member 3. An internal hexagon screw 402 passes through the central axis of the two annular rubber pads 401. A nut 403 is installed on the outer wall of the internal hexagon screw 402. The nut 403 is located above one of the annular rubber pads 401.
[0035] Both ends of the clamping plate 5 are fixed to the guide member 3 by the internal hex screws 402 and the nuts 403;
[0036] Each clamping plate 5 has multiple mounting slots 501 inside, and each mounting slot 501 has a limiting block 502 installed inside. Two semi-circular slots 503 are symmetrically opened on the inner wall of the limiting block 502.
[0037] Multiple insertion and removal limiting members 6 are installed in the mounting groove 501, and one end of each insertion and removal limiting member 6 abuts against the bottom of the die-cutting plate 7.
[0038] First, the upper template 1 is the load-bearing structure of the fixture. The two workstations 2 inside provide an installation area for the die-cutting plate 7. The two guides 3 inside the workstations 2 provide an installation carrier for the fasteners 4 and the clamping plates 5. After determining the installation position of the die-cutting plate 7, the hexagonal screws 402 and nuts 403 are in a loose state, which is convenient for adjustment. The operator needs to move the two clamping plates 5 first to make them fit against both sides of the die-cutting plate 7 to prepare for the subsequent fixing operation.
[0039] Next, use a hex wrench to tighten the hex screws 402 at both ends of each clamping plate 5. As the hex screws 402 and nuts 403 are gradually tightened, the two circular rubber pads 401 clamped in the middle are squeezed and deformed. The circular rubber pads 401 enhance the friction between the fastener 4 and the guide 3, preventing loosening. On the other hand, it avoids damage between the fastener 4 and the guide 3 due to rigid contact. Repeat the above operation to firmly fix the two ends of the two clamping plates 5 to the guide 3, thereby completing the stable clamping of the die-cutting plate 7 in the left and right directions.
[0040] Finally, the die-cutting plate 7 is fixed vertically. Since the clamping plate 5 has several mounting slots 501, after the die-cutting plate 7 is placed, several mounting slots 501 will also appear at the corresponding positions. The operator inserts the insertion / removal limiting piece 6 into each mounting slot 501 sequentially, passing it through the two semi-circular slots 503 on the limiting block 502 to the other side. Then, the corresponding component of the insertion / removal limiting piece 6 is rotated to create a misalignment with the semi-circular slot 503, thus limiting the insertion / removal limiting piece 6. During this process, the spring inside the insertion / removal limiting piece 6... The insertable component contacts the limiting block 502 and is compressed as it continues to enter. As more insertable limiting components 6 are inserted into each mounting slot 501, several insertable limiting components 6 press against the die-cutting plate 7 from below. Together with the clamping plates 5 on both sides, the die-cutting plate 7 is finally clamped and fixed. Through the two adjustable clamping plates 5 and the insertable limiting components 6, the limiting range for different sizes of die-cutting plates 7 can be flexibly adjusted, so that enterprises do not need to frequently change fixtures to replace the die-cutting plate 7, which greatly shortens the production preparation time.
[0041] In one embodiment, the guide member 3 includes two mounting plates 301, both of which are fixedly mounted on the inner wall of the upper template 1. Two L-shaped guide rods 302 are fixedly connected between the two mounting plates 301, and the two L-shaped guide rods 302 are symmetrically arranged.
[0042] The two L-shaped guide rods 302 are located between the two circular rubber gaskets 401, and the two L-shaped guide rods 302 are located on opposite sides of the nut 403. The hex socket screw 402 passes through the gap between the two L-shaped guide rods 302.
[0043] Two symmetrically arranged L-shaped guide rods 302 are connected between two mounting plates 301. The two mounting plates 301 provide a foundation for the two L-shaped guide rods 302 to be installed on the upper template 1. The two L-shaped guide rods 302 are located between two circular rubber gaskets 401. When the hex socket screw 402 and nut 403 are tightened, the hex socket screw 402 and nut 403 can squeeze the two circular rubber gaskets 401, increasing the friction between the fastener 4 as a whole and the two L-shaped guide rods 302. The two L-shaped guide rods 302 are located on opposite sides of the nut 403. When the hex socket screw 402 is tightened with a hex wrench, when the nut 403 is subjected to tightening force and attempts to rotate, the two L-shaped guide rods 302 located on opposite sides will directly block the rotation path of the nut 403, forcing the nut to move only along the thread direction of the hex socket screw 402.
[0044] In one embodiment, the limiting block 502 is fixedly connected to the clamping plate 5.
[0045] The limiting block 502 is fixed on the clamping plate 5, thereby limiting the insertion and removal limiting member 6 so that the insertion and removal limiting member 6 is fixed to the die-cutting plate 7.
[0046] In one embodiment, the insertion / removal limiting member 6 includes a blade clamp 601, on which a rotating rod 602 is rotatably mounted.
[0047] One end of the rotating rod 602 is fixedly connected to an internal hexagon head 603, and two semi-circular blocks 604 are symmetrically installed on the outer wall of the end of the rotating rod 602 away from the internal hexagon head 603.
[0048] One end of the blade clamp 601 abuts against the bottom of the die-cutting plate 7, and an elastic element 605 is installed on one end of the blade clamp 601. The elastic element 605 is sleeved around the rotating rod 602.
[0049] When fixing the die-cutting plate 7 vertically, the operator first inserts the rotating rod 602 into the mounting groove 501 of the clamping plate 5. At this time, the two semicircular blocks 604 on the rotating rod 602 are aligned with the two semicircular grooves 503 on the limiting block 502. After the semicircular blocks 604 pass through the semicircular grooves 503, the hex wrench is used to turn the internal hex head 603, causing the rotating rod 602 to rotate. As the rotating rod 602 rotates, the originally aligned semicircular blocks 604 and semicircular grooves 503 become misaligned, and the semicircular blocks 604 abut against one side of the limiting block 502. At this time, the inner ring of the limiting block 502 forms a block, restricting the displacement of the semicircular blocks 604 and firmly locking them in the space formed by the limiting block 502 and the clamping plate 5 in the mounting groove 501, thereby restricting the vertical movement of the semicircular blocks 604. The internal hex head 603 forms an axial force on the tool holder 601. The clamping plate 601 is designed to prevent vertical movement of the blade clamp 601, thus ensuring that the end of the blade clamp 601 reliably abuts against the die-cutting plate 7 and limits its vertical movement. During the insertion of the rotating rod 602 into the mounting slot 501, the elastic element 605 (preferably a spring) at one end of the blade clamp 601 contacts and compresses with the limiting block 502, generating a reverse elastic force. On the one hand, this enhances the friction between the blade clamp 601 and the internal hexagon head 603, effectively resisting vibrations during the die-cutting process and preventing relative rotation between the two. On the other hand, when the die-cutting plate 7 needs to be disassembled, the elastic potential energy stored in the elastic element 605 is released, providing a pushing force for pulling out the insertion and removal limiting element 6, allowing the operator to easily remove it. In addition, the clamping plate 5 has a slot for placing each blade clamp 601, which also prevents rotation between the blade clamp 601 and the internal hexagon head 603.
[0050] Working principle: When installing the die-cutting plate 7, first adjust the hex socket screws 402 and nuts 403 to a loose state. The operator moves the two clamping plates 5 to fit against both sides of the die-cutting plate 7. Then, use a hex wrench to tighten the hex socket screws 402 at both ends of the clamping plate 5. The hex socket screws 402 and nuts 403 are gradually tightened, causing the circular rubber gaskets 401 located at the upper and lower ends of the guide 3 to deform, which enhances the friction between the fasteners 4 and the guide 3, thereby firmly fixing the clamping plate 5 on the guide 3 and completing the clamping of the die-cutting plate 7 in the left and right directions.
[0051] After the left and right sides are fixed, the worker inserts the rotating rod 602 of the insertion and removal limiting part 6 into the mounting groove 501. At this time, the semi-circular block 604 at the end of the rotating rod 602 is aligned with the semi-circular groove 503 of the limiting block 502, so that the semi-circular block 604 can pass smoothly through the semi-circular groove 503. After passing through, the rotating rod 602 is rotated by turning the internal hexagonal head 603 with a hexagonal wrench, so that the semi-circular block 604 is misaligned with the semi-circular groove 503. The inner ring of the limiting block 502 blocks the displacement of the semi-circular block 604, locking it in the space formed by the limiting block 502 and the clamping plate 5 in the mounting groove 501. This makes the internal hexagonal head 603 form an axial constraint on the knife clamp 601, so that the end of the knife clamp 601 abuts against the die-cutting plate 7, realizing the upper and lower limit.
