Description

Technical Field

[0001] This disclosure pertains to the field of machining, and specifically relates to a base for a punching machine and the punching machine itself. Background Technology

[0002] A punching machine is a device used to process holes in various types of flat plates.

[0003] In related technologies, a punching machine includes a base for mounting a punch, which performs punching operations on the workpiece. After prolonged use, the punch will wear down and therefore needs to be replaced.

[0004] However, changing the punch requires disassembling the machine base, which is assembled using bolts, making disassembly and reassembly relatively difficult. Furthermore, the bolts are prone to loosening due to vibrations generated during the punching machine's operation, posing a safety hazard. Summary of the Invention

A first end of the piston portion is located on one side of the inner flange, and a second end of the piston portion is located on the other side of the inner flange. The locking head is connected to the second end of the piston portion.

[0017] In another implementation of this disclosure, the actuating mechanism includes a push block, a rotating shaft, and a toggle block;

[0018] The push block is movably located within the first accommodating groove and the second accommodating groove. The push block has a movable hole. The rotating shaft is located on the side of the push block facing away from the second locking mechanism. The rotating shaft is rotatably inserted into the second connecting base, and at least a portion of the rotating shaft is rotatably located within the movable hole. The toggle block is connected to the rotating shaft, and the toggle block is rotatably located within the movable hole. The rotation trajectory of the toggle block passes through the push block.

[0026] The positioning component includes a positioning member, an unlocking member, and a fourth elastic member. The positioning member has a second reverse tooth on one side, which can engage with the first reverse tooth. The fourth elastic member is located on the other side of the positioning member and is connected to the inner wall of the accommodating cavity and the positioning member respectively. The unlocking member is movably located in the accommodating cavity and is used to drive the positioning member to move away from the pin to release the engagement between the second reverse tooth and the first reverse tooth.

[0027] On the other hand, embodiments of this disclosure provide a punching machine, which includes the machine base described above.

[0028] The beneficial effects of the technical solutions provided in this disclosure are:

[0029] The punching machine base provided in this embodiment includes a first connecting base, a second connecting base, and a first locking mechanism. After the base is configured with the punching machine, the first connecting base is used to connect the moving mechanism of the punching machine, and the second connecting base is used to connect the punch of the punching machine. During the assembly of the first and second connecting bases, the first and second connecting bases are brought together so that a first locking member is inserted into a first locking groove. Then, driven by a first elastic member, the locking shaft locks the first locking member located in the first locking groove, keeping the first locking member in the first locking groove, thereby realizing the assembly between the first and second connecting bases. During the process of disassembling the first and second connecting bases to replace the punch, the locking shaft is pulled, causing the locking shaft to move away from the first locking member, thereby releasing the lock on the first locking member, and allowing the first locking member to be pulled out of the first locking groove, realizing the disassembly between the first and second connecting bases.

[0030] In other words, the base of the punching machine provided in this embodiment of the present disclosure, through the first locking mechanism, enables quick assembly and disassembly between the first connecting base and the second connecting base. Furthermore, since no bolts are used, there are no safety hazards caused by loose bolts, effectively improving reliability. Attached Figure Description

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concepts of this disclosure to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0053] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0054] This disclosure provides a punching machine. Figure 1 See the schematic diagram of the punching machine. Figure 1 In this embodiment, the punching machine includes a base 100, which is used to mount a punch 200 to punch the workpiece.

[0055] In this embodiment, the punching machine also includes a support 300, a moving mechanism 400, and a lifting frame 500.

[0056] The moving mechanism 400 includes a first driving member 401, a translation member 402, and a first lifting member 403. The first driving member 401 is connected to the support 300, and the translation member 402 is connected to the first driving member 401. The translation member 402 can move relative to the support 300 in a horizontal direction. The first lifting member 403 is connected to both the translation member 402 and the lifting frame 500. The first lifting member 403 can drive the lifting frame 500 to move relative to the support 300 in a vertical direction.

[0057] For example, the first driving component 401 is a motor, and the first driving component 401 and the translation component 402 can be connected by a gear and rack mechanism or the like, thereby driving the translation component 402 to move in the horizontal direction. The first lifting component 403 is a hydraulic cylinder, the cylinder body of which is connected to the translation component 402, and the piston rod of which is connected to the lifting frame 500. The extension and retraction of the piston rod drives the lifting frame 500 to move in the vertical direction.

[0058] The lifting frame 500 includes a frame body 501, a second lifting member 502, a first positioning tooth 503, and a second driving member 504. The frame body 501 is connected to the first lifting member 403. The second lifting member 502 is located on the side of the frame body 501 facing away from the first lifting member 403, and the second lifting member 502 is connected to both the frame body 501 and the first positioning tooth 503. The second lifting member 502 can drive the first positioning tooth 503 to move relative to the bracket 300. The direction of movement of the first positioning tooth 503 is vertical. The second driving member 504 is connected to the frame body 501, and the drive shaft of the second driving member 504 is connected to the base 100.

[0059] For example, the second driving component 504 is a motor, and the motor's rotating shaft is inserted into the base 100, thereby driving the base 100 to rotate around the motor's rotating shaft. The second lifting component 502 is a hydraulic cylinder, the cylinder body of which is connected to the frame 501, and the piston rod of which is connected to the first positioning tooth 503. The extension and retraction of the piston rod drives the first positioning tooth 503 to move in the vertical direction. By driving the first positioning tooth 503 to move through the second lifting component 502, the first positioning tooth 503 can abut against the base 100, thereby locking the position of the base 100 after rotation.

[0060] Figure 2 This is a schematic diagram of the machine base, combined with... Figure 2 In this embodiment, the base includes a first connecting base 10, a second connecting base 20, and a first locking mechanism 30.

[0061] One side of the first connecting base 10 has a first locking groove 110. One side of the second connecting base 20 has a first locking member 210. The second connecting base 20 abuts against the first connecting base 10, and the first locking member 210 is inserted into the first locking groove 110. The first locking mechanism 30 includes a support frame 310, a first elastic member 320, and a locking shaft 330. The support frame 310 is connected to the outer wall of the first connecting base 10. The first elastic member 320 is connected to both the support frame 310 and the locking shaft 330. The locking shaft 330 is slidably connected to the support frame 310. At least a portion of the locking shaft 330 is slidably inserted into the first connecting base 10, so that the locking shaft 330 can lock the first locking member 210 located in the first locking groove 110 under the drive of the first elastic member 320.

[0062] After the base is installed on the punching machine, the first connecting base 10 is used to connect the moving mechanism of the punching machine, and the second connecting base 20 is used to connect the punch of the punching machine. During the assembly of the first connecting base 10 and the second connecting base 20, the first connecting base 10 and the second connecting base 20 are brought together so that the first locking member 210 is inserted into the first locking groove 110. Then, driven by the first elastic member 320, the locking shaft 330 locks the first locking member 210 located in the first locking groove 110, so that the first locking member 210 is held in the first locking groove 110, thereby realizing the assembly between the first connecting base 10 and the second connecting base 20. During the process of disassembling the first connecting base 10 and the second connecting base 20 to replace the punch, the locking shaft 330 is pulled to move the locking shaft 330 away from the first locking member 210, thereby releasing the lock on the first locking member 210, and then the first locking member 210 can be pulled out of the first locking groove 110, thus realizing the disassembly between the first connecting base 10 and the second connecting base 20.

[0063] In other words, the base of the punching machine provided in this embodiment of the present disclosure, through the first locking mechanism 30, enables quick assembly and disassembly between the first connecting base 10 and the second connecting base 20. Furthermore, since no bolts are used, there are no safety hazards caused by loose bolts, effectively improving reliability.

[0064] The first connecting base 10 has a second positioning tooth 150 on the side facing away from the second connecting base 20. The second positioning tooth 150 can mesh with the first positioning tooth 503. The first positioning tooth 503 moves toward the base under the drive of the second lifting member 502 until the first positioning tooth 503 meshes with the second positioning tooth 150, thereby achieving positioning of the base.

[0065] See also Figure 2 In this embodiment, one side of the first connecting base 10 has a second locking groove 120 and a first receiving groove 130, which are located on the same surface and spaced apart from each other. One side of the second connecting base 20 has a second locking member 220 and a second receiving groove 230, which are located on the same surface and spaced apart from each other. The second locking member 220 is inserted into the second locking groove 120, and the second receiving groove 230 and the first receiving groove 130 are arranged opposite to each other. The base of the punching machine also includes a second locking mechanism 40 and a toggle mechanism 50. The second locking mechanism 40 is located in the first receiving groove 130, and the toggle mechanism 50 is located in the second receiving groove 230. The toggle mechanism 50 is used to move the second locking mechanism 40 so that the second locking mechanism 40 locks the second locking member 220 located in the second locking groove 120.

[0066] In the above implementation, the second locking groove 120 is used to accommodate the second locking member 220. When the first connecting base 10 and the second connecting base 20 abut against each other, the second locking member 220 can be inserted into the second locking groove 120. In this case, the second locking mechanism 40 is moved by the toggle mechanism 50, so that the second locking mechanism 40 locks the second locking member 220 located in the second locking groove 120 under the drive of the toggle mechanism 50, so that the second locking member 220 is kept in the second locking groove 120, thereby realizing the assembly between the first connecting base 10 and the second connecting base 20.

[0067] Since the second locking member 220 needs to cooperate with the second locking mechanism 40, the second locking member 220 is closer to the second locking mechanism 40 than the first locking member 210, that is, the second locking groove 120 is closer to the first receiving groove 130 than the first locking groove 110.

[0068] For example, the number of first locking members 210 and first receiving slots 130 corresponds one-to-one, and the number of second locking members 220 and second receiving slots 230 also corresponds one-to-one. The number of first locking members 210 and second locking members 220 can be adjusted according to actual needs, such as two or three. If there are multiple first locking members 210 and second locking members 220, then the second locking members 220 are arranged around the second receiving slot 230, and the first locking members 210 are arranged around the second locking members 220.

[0069] See also Figure 2 In this embodiment, the first connecting base 10 has an oil passage 140, and the first end of the oil passage 140 is connected to the second locking groove 120. The second locking mechanism 40 includes an oil tank 410, a driving piston 420, and a locking piston 430. The oil tank 410 is connected to the inner wall of the first receiving groove 130 and is connected to the second end of the oil passage 140. The first end of the driving piston 420 is movably located inside the oil tank 410, and the second end of the driving piston 420 is located outside the oil tank 410 and faces the actuating mechanism 50. The first end of the locking piston 430 is movably located inside the first end of the oil passage 140, and the second end of the locking piston 430 is located outside the oil passage 140 and faces the second locking member 220.

[0070] In the above implementation, the oil tank 410 is used to store hydraulic oil. The oil tank 410 is connected to the second end of the oil passage 140, enabling the hydraulic oil to flow between the oil tank 410 and the oil passage 140. The drive piston 420 is movably located inside the oil tank 410, and the locking piston 430 is movably located inside the oil passage 140. By means of the actuating mechanism 50, the drive piston 420 can be moved, thereby causing the locking piston 430 to move synchronously through the action of the hydraulic oil, thus achieving the locking of the locking piston 430 onto the second locking member 220.

[0071] For example, the number of locking pistons 430 and second locking members 220 are one-to-one, the number of oil passages 140 and locking pistons 430 are one-to-one, and the second end of each oil passage 140 is connected to the oil tank 410. Thus, by moving a driving piston 420, the synchronous driving of each locking piston 430 can be achieved, thereby realizing the synchronous locking of each locking piston 430 to each second locking member 220.

[0072] It is worth noting that since the locking piston 430 is located inside the first end of the oil passage 140, the sealing fit between the locking piston 430 and the oil passage 140 ensures that the hydraulic oil in the oil passage 140 will not leak into the second locking groove 120 through the first end of the oil passage 140.

[0073] Figure 3 for Figure 2 A magnified view of a portion of area A, combined with Figure 3 In this embodiment, the oil passage 140 has an inner flange 141 near the first end. The locking piston 430 includes a piston portion 431 and a locking head 432. The piston portion 431 is movably and sealingly inserted into the inner flange 141. The first end of the piston portion 431 is located on one side of the inner flange 141, and the second end of the piston portion 431 is located on the other side of the inner flange 141. The locking head 432 is connected to the second end of the piston portion 431.

[0074] In the above implementation, the piston portion 431 is movably and sealingly inserted into the inner flange 141, thereby enabling the locking piston 430 to seal the first end of the oil pipe. The first end of the piston portion 431 is located on one side of the inner flange 141 and is in contact with the hydraulic oil, while the second end of the piston portion 431 is located on the other side of the inner flange 141 and is used to push the locking head 432. Under the push of the piston portion 431, the locking head 432 can be inserted into the second locking member 220, thereby locking the second locking member 220.

[0075] For example, the locking head 432 is a frustum-shaped structure, the outer wall of the second locking member 220 has a groove that matches the shape of the locking head 432, the larger end of the locking head 432 is connected to the piston portion 431, and the smaller end of the locking head 432 faces the second locking member 220.

[0076] This design facilitates the insertion of the locking head 432 into the second locking member 220.

[0077] See you again Figure 2 In this embodiment, the actuating mechanism 50 includes a push block 510, a rotating shaft 520, and a toggle block 530. The push block 510 is movably located in the first receiving groove 130 and the second receiving groove 230, and has a movable hole 511. The rotating shaft 520 is located on the side of the push block 510 facing away from the second locking mechanism 40, and is rotatably inserted into the second connecting base 20. At least a portion of the rotating shaft 520 is rotatably located in the movable hole 511. The toggle block 530 is connected to the rotating shaft 520, and is rotatably located in the movable hole 511. The rotation trajectory of the toggle block 530 passes through the push block 510.

[0078] In the above implementation, the first receiving groove 130 and the second receiving groove 230 are opposite to and connected, so that the first receiving groove 130 and the second receiving groove 230 can together form a space, and the push block 510 can move vertically within this space. During the rotation of the rotating shaft 520, the push block 530 rotates together with the rotating shaft 520.

[0079] Figure 4 This is a schematic diagram showing the arrangement of the levers within the movable hole. Figure 4 The perspective is Figure 2 The side view, combined with Figure 4 Since the rotation trajectory of the toggle block 530 passes through the push block 510, the rotating toggle block 530 will push the push block 510, causing the push block 510 to move toward the second locking mechanism 40, thereby moving the second locking mechanism 40 so that the second locking mechanism 40 locks the second locking member 220 located in the second locking groove 120.

[0080] For example, the push block 510 includes a connected support portion 512 and a pushing portion 513. The side of the support portion 512 facing away from the pushing portion 513 abuts against the second end of the drive piston 420, and the movable hole 511 is located inside the pushing portion 513. When the toggle block 530 contacts the inner wall of the movable hole 511 near the support portion 512, as the toggle block 530 rotates, it can push the pushing portion 513, along with the support portion 512, towards the drive piston 420, thereby causing the drive piston 420 to drive the locking piston 430 to move via hydraulic oil.

[0081] For example, the toggle block 530 is a cam-shaped structure, and the toggle block 510 is achieved by the swinging of the cam tip.

[0082] See also Figure 2 In this embodiment, the bottom of the second receiving groove 230 has a guide groove 240, and the extending direction of the guide groove 240 is consistent with the moving direction of the push block 510. The actuating mechanism 50 also includes a guide rod 540, the end of which is connected to the push block 510, and the guide rod 540 is movably inserted into the guide groove 240.

[0083] In the above implementation, since the extension direction of the guide groove 240 is consistent with the movement direction of the push block 510, the sliding cooperation between the guide rod 540 and the guide groove 240 can effectively guide the movement of the push block 510, thereby preventing the push block 510 from swaying during the movement.

[0084] For example, the number of guide grooves 240 and guide rods 540 are in one-to-one correspondence, and the guide rods 540 are inserted into the corresponding guide rods 540. The number of guide rods 540 can be adjusted according to actual requirements. If there are multiple guide rods 540, then the guide rods 540 are arranged in parallel and spaced apart from each other.

[0085] In this embodiment, the actuating mechanism 50 further includes a second elastic element 550, which is located in the guide groove 240 and is connected to the inner wall of the guide groove 240 and the guide rod 540, respectively.

[0086] In the above implementation, the second elastic element 550 always provides the push block 510 with a tendency to move away from the drive piston 420. When the rotating shaft 520 drives the dial block 530 to rotate in the forward direction, it pushes the push block 510 to overcome the elastic force of the second elastic element 550 and move towards the drive piston 420. When the rotating shaft 520 drives the dial block 530 to rotate in the reverse direction, the elastic force of the second elastic element 550 is released, thereby pulling the push block 510 to move away from the drive piston 420 and thus reset.

[0087] For example, the second elastic element 550 is a helical spring, one end of the second elastic element 550 is connected to the end of the guide rod 540, and the other end of the second elastic element 550 is connected to the bottom of the guide groove 240.

[0088] Figure 5 for Figure 2 A magnified view of region B, combined with Figure 5 In this embodiment, one end of the rotating shaft 520 is located outside the second connecting base 20. The actuating mechanism 50 also includes a turntable 570 and a stop 580. The turntable 570 is connected to the end of the rotating shaft 520 located outside the second connecting base 20. The turntable 570 has a through hole 590 for accommodating tools such as levers, so as to facilitate turning the turntable 570. The stop 580 is connected to the outer wall of the turntable 570, and one side of the stop 580 faces the end of the through hole 590. When a tool such as a lever passes through the through hole 590, its end can abut against the stop 580, thereby playing a positioning role.

[0089] Figure 6 for Figure 2 A magnified view of region C, combined with Figure 6 In this embodiment, the actuating mechanism 50 further includes a third locking member 560, which is connected to the rotating shaft 520 and located within the second receiving groove 230. The base of the punching machine also includes a third locking mechanism 60, which includes a pin 610, a third elastic member 620, and a positioning component 630. The pin 610 is movably inserted into the second connecting base 20. The third elastic member 620 is connected to the inner wall of the second connecting base 20 and the pin 610, respectively. The third elastic member 620 is used to drive the pin 610 to move away from the third locking member 560. The positioning component 630 is located within the receiving cavity 250 of the second connecting base 20 and is used to position the pin 610 so that the first end of the pin 610 can lock the third locking member 560.

[0090] In the above implementation, the third locking member 560 can rotate together with the rotating shaft 520. The pin 610 is movably inserted into the second connecting base 20. When the first end of the pin 610 abuts against the third locking member 560, the first end of the pin 610 locks the third locking member 560. However, when the first end of the pin 610 separates from the third locking member 560, the first end of the pin 610 releases its lock on the third locking member 560. The positioning component 630 is disposed within the receiving cavity 250 of the second connecting base 20 and can position the pin 610, thereby maintaining the pin 610's lock on the third locking member 560. Furthermore, under the action of the third elastic member 620, if the positioning component 630 releases the positioning of the pin 610, then under the action of the third elastic member 620, the pin 610 will be driven to move away from the third locking member 560, thereby resetting the pin 610.

[0091] For example, the inner wall of the second receiving groove 230 has a sliding groove 260. The first end of the pin 610 and the third elastic member 620 are both located in the sliding groove 260. The third elastic member 620 is sleeved on the outside of the pin 610 and compressed between the first end of the pin 610 and the bottom of the sliding groove 260. When the rotating shaft 520 rotates to drive the toggle block 530 to push the push block 510 into place, that is, when the locking piston 430 locks the second locking member 220 into place, the third locking member 560 rotates to the position corresponding to the sliding groove 260 under the drive of the rotating shaft 520, so that the first end of the pin 610 can extend out of the sliding groove 260 to lock the third locking member 560.

[0092] The second end of the pin 610 is located outside the second connecting base 20 for easy operation.

[0093] See also Figure 6 In this embodiment, the outer wall of the pin 610 has a first reverse tooth 611, and the positioning component 630 includes a positioning member 631, an unlocking member 632, and a fourth elastic member 633. One side of the positioning member 631 has a second reverse tooth 634, which can engage with the first reverse tooth 611. The fourth elastic member 633 is located on the other side of the positioning member 631, and the fourth elastic member 633 is connected to the inner wall of the accommodating cavity 250 and the positioning member 631 respectively. The unlocking member 632 is movably located in the accommodating cavity 250. The unlocking member 632 is used to drive the positioning member 631 to move away from the pin 610 to release the engagement between the second reverse tooth 634 and the first reverse tooth 611.

[0094] In the above implementation, the fourth elastic member 633 is connected to the inner wall of the accommodating cavity 250 and the positioning member 631. Under the action of the fourth elastic member 633, the positioning member 631 can move towards the pin 610, so that the second reverse tooth 634 on the positioning member 631 and the first reverse tooth 611 on the pin 610 mesh, thereby locking the pin 610 and keeping it locked to the third locking member 560. The unlocking member 632 is movably located in the accommodating cavity 250. By moving the unlocking member 632, the positioning member 631 can be driven to move away from the pin 610, thereby releasing the meshing between the second reverse tooth 634 and the first reverse tooth 611, and thus allowing the pin 610 to move away from the third locking member 560 under the action of the third elastic member 620, realizing the reset of the pin 610.

[0095] Exemplarily, the unlocking member 632 includes a push rod 635 and a wedge 636. The push rod 635 is movably inserted into the second connecting base 20, with one end of the push rod 635 located outside the second connecting base 20 and the second end of the push rod 635 located within the receiving cavity 250, and the second end of the push rod 635 is connected to the wedge 636. The inclined surface of the wedge 636 faces away from the pin 610, and the inclined surface of the wedge 636 slides in contact with the positioning member 631.

[0096] In the above implementation, the wedge 636 can be moved by pushing the first end of the push rod 635. During the movement of the wedge 636, the inclined surface of the wedge 636 gradually pushes the positioning member 631 away from the pin 610, thereby disengaging the engagement between the second reverse tooth 634 and the first reverse tooth 611.

[0097] The following describes the disassembly process of the punching machine base:

[0098] 1. Retract the second lifting component 502 to disengage the first positioning tooth 503 and the second positioning tooth 150 from each other.

[0099] 2. The base is rotated by the second drive component 504 until the position of the base is adjusted to a state suitable for disassembly.

[0100] 3. Push the first end of push rod 635 to move wedge block 636. During the movement of wedge block 636, the inclined surface of wedge block 636 gradually pushes positioning member 631 away from pin 610, thereby disengaging the engagement between second reverse tooth 634 and first reverse tooth 611. Under the action of third elastic member 620, pin 610 moves away from third locking member 560, thereby releasing the locking of third locking member 560.

[0101] 4. After the third locking member 560 is unlocked, under the action of the second elastic member 550, the push block 510 moves away from the drive piston 420 to reset. At the same time, the push block 510 drives the drive piston 420 to move and reset together. Under the action of hydraulic oil, the locking piston 430 moves away from the second locking member 220, thereby releasing the lock on the second locking member 220.

[0102] 5. Pull the locking shaft 330 to move it away from the first locking member 210, thereby releasing the lock on the first locking member 210.

[0103] 6. Pull the first locking member 210 out of the first locking groove 110 and pull the second locking member 220 out of the second locking groove to realize the disassembly between the first connecting base 10 and the second connecting base 20.

[0104] The installation process of the punching machine base is similar to the disassembly process, but in reverse, so it will not be described in detail here.
