Description

Technical Field

[0001] This utility model relates to the field of key production equipment technology, and in particular to a key machine. Background Technology

[0002] After the key blank is machined with the corresponding teeth on both sides, the key machine can form the corresponding key. After the teeth are machined, the edges of the teeth will form burrs, which is not conducive to their mating with the lock cylinder. Therefore, during the key manufacturing process, a burr removal operation is performed on the teeth after machining.

[0003] In the prior art, after the key blank is processed with the corresponding teeth on the key machine, it is usually transferred from the key machine to the corresponding deburring device by manual means. Then, the deburring device is used to deburr the teeth of the key, thereby completing the final processing of the key.

[0004] However, this key processing method has low production efficiency. Utility Model Content

[0040] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0041] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element 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 this utility model.

[0042] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0043] like Figure 1 As shown, in one embodiment, the key machine 10 includes a fixture 1, a conveying device 2, a first processing device 3, a first deburring device 4, and a flipping device 5; the fixture 1 is connected to the conveying device 2 and is used to hold the key; the conveying device 2 is used to drive the fixture 1 to move so that it can move to a first station and a second station; the first processing device 3 is used to process the first teeth of the key on the fixture 1 located at the first station; the first deburring device 4 is used to deburr the first teeth of the key on the fixture 1 located at the second station; the flipping device 5 is used to flip the key on the fixture 1 located at the second station that has been deburred by the first deburring device 4.

[0044] In this application, a deburring device (i.e., a first deburring device 4) is integrated into the key machine 10. In this way, during the key processing, the key can be deburred without moving it from the key machine 10 to the corresponding deburring device outside the key machine 10, thereby improving the key processing efficiency.

[0045] In addition, the first deburring device 4 can perform deburring operation on the key at the second station, and the flipping device 5 can perform flipping operation at the second station. That is, when the key with the first tooth is moved from the first station to the second station, the deburring operation and flipping operation can be realized without moving it again, thereby further improving the production efficiency of the key machine 10.

[0046] It should be noted that the key on fixture 1 at the first workstation is actually a key blank. For simplicity, all forms of the key blank during the process of being processed into the final key are referred to as keys in this article. Machining the first tooth of the key means machining the first tooth on the key.

[0047] like Figure 2 As shown, in one embodiment, the fixture 1 includes a first clamping part 11, a second clamping part 12, and a clamping drive assembly 13. The first clamping part 11 is used to hold a key, and the clamping drive assembly 13 is connected to the second clamping part 12 and is used to drive the second clamping part 12 to move relative to the first clamping part 11, so that the first clamping part 11 and the second clamping part 12 can clamp or release the key on the first clamping part 11.

[0048] The first clamping part 11 has a bearing surface 111, on which a stop 112 is provided. The key placed on the first clamping part 11 is actually placed on the bearing surface 111. The second clamping part 12 can press the key on the bearing surface 111 against the stop 112, thereby clamping the key. In addition, after the two clamping parts clamp the key, they will not obstruct or interfere with the surface of the key where the first tooth needs to be machined.

[0049] In one embodiment, the clamping drive assembly 13 is used to drive the second clamping part 12 to rotate relative to the first clamping part 11, thereby enabling it to clamp or release the key in conjunction with the first clamping part 11.

[0050] At this time, the clamping drive assembly 13 can be a power source including a rotary motor, rotary cylinder, electromagnet, or linear cylinder, which can provide driving force to drive the second clamping part 12 to rotate. In addition, these power sources can all be existing designs, and the way they drive an object to rotate is also an existing design.

[0051] like Figure 2 As shown, in one embodiment, the first clamping part 11, the second clamping part 12, and the clamping drive assembly 13 are all disposed on the corresponding support member 6. The first clamping part 11 may be fixed to the support member 6, the second clamping part 12 may be rotatably connected to the support member 6, and the clamping drive assembly 13 may connect the support member 6 and the second clamping part 12.

[0052] Of course, in other embodiments, the clamping drive assembly 13 may also drive the second clamping part 12 to move linearly so that it can cooperate with the first clamping part 11 to clamp or release the key. In addition, the fixture 1 may also adopt other existing designs, which will not be described in detail in this embodiment.

[0053] like Figure 1As shown, in one embodiment, the conveying device 2 includes a turntable 21 and a conveying drive assembly. The fixture 1 is mounted on the turntable 21, and the conveying drive assembly is connected to the turntable 21 and is used to drive the turntable 21 to rotate so as to move the fixture 1 to the first station and the second station.

[0054] In one embodiment, the axis around which the turntable 21 rotates, driven by the conveying drive assembly, is parallel to the vertical direction. Furthermore, the turntable 21 can rotate about its own axis.

[0055] Of course, in other embodiments, the conveying device 2 can also be moved to the first and second workstations by driving the fixture 1 to move linearly. Furthermore, the conveying device 2 can also be configured using other existing designs, which will not be described in detail here.

[0056] like Figure 3 As shown, in one embodiment, the first deburring device 4 includes a first drive module 41, a second drive module 42, and a scraper 43; the first drive module 41 drives the scraper 43 to move along a first direction to approach or move away from the fixture 1 located at the second workstation; wherein, when the scraper 43 approaches the fixture 1 along the first direction, it can press the key on the fixture 1; the second drive module 42 drives the scraper 43 to move along a second direction so that the scraper 43 can deburr the key pressed by it; the first direction and the second direction intersect. Figure 3 In the example shown, the first direction is parallel to the Z-axis, and the second direction is parallel to the X-axis. Alternatively, the first direction can be perpendicular to the second direction.

[0057] During operation, the first drive module 41 drives the scraper 43 to approach the fixture 1 and press it onto the key on the fixture 1. Then, the second drive module 42 drives the scraper 43 to move in the second direction so that the scraper 43 removes the burrs from the first tooth.

[0058] The first processing device 3 can process corresponding toothed grooves on the surface of the key, and the toothed grooves extend to the tip of the key to form the first tooth.

[0059] When the scraper 43 presses down on the key, a portion of the scraper 43 is located within the tooth recess. When the key moves to the second position, the extension direction of the tooth recess is parallel to the second direction. Therefore, as the scraper 43 moves within the tooth recess along the second direction, it can scrape away the burrs around the tooth recess.

[0060] It should be understood that the processing method of the first tooth, the structure of the scraper 43, and the principle by which the scraper 43 removes the burrs from the key are all existing technologies.

[0061] In one embodiment, the first drive module 41 is connected to the second drive module 42, and the scraper 43 is connected to the first drive module 41. During operation, the second drive module 42 can drive the first drive module 41 and the scraper 43 to move together in a second direction.

[0062] Of course, in other embodiments, the second drive module 42 can be connected to the first drive module 41, and the scraper 43 can be connected to the second drive module 42. In this case, the first drive module 41 can drive the second drive module 42 and the scraper 43 to move together in the first direction.

[0063] It should be understood that the first drive module 41 can drive the scraper 43 to reciprocate along the first direction, and the second drive module 42 can drive the scraper 43 to reciprocate along the second direction.

[0064] In one application scenario, the first direction is parallel to the vertical direction. In this scenario, when the fixture 1 moves to the second station, the scraper 43 is positioned above it. When the scraper 43 moves downward, it can approach the fixture 1; when the scraper 43 moves upward, it can move away from the fixture 1.

[0065] like Figure 3 and Figure 4 As shown, in one embodiment, the first drive module 41 includes a first support component 44, a first drive component 45, and a first connecting component 46; the first support component 44 is connected to the second drive module 42; the first drive component 45 is connected to the first connecting component 46; the scraper 43 is connected to the first connecting component 46; the first drive component 45 is used to drive the first connecting component 46 to reciprocate along a first direction, so as to drive the scraper 43 to move closer to or away from the fixture 1 located at the second work station; the first connecting component 46 can elastically extend and retract in the first direction.

[0066] When the scraper 43 moves along the first direction towards the fixture 1 to press the key, the elastic extension and retraction of the first connecting component 46 prevents the scraper 43 from rigidly colliding with the key, thus improving the service life of the scraper 43. Simultaneously, the elastic force generated by the elastic contraction of the first connecting component 46 can also press the scraper 43 onto the key. Furthermore, when the scraper 43 is subsequently driven to move along the second direction, the elastic extension and retraction of the first connecting component 46 ensures that the scraper 43 remains in contact with the key and adapts to the key's movement.

[0067] In one embodiment, the scraper 43 and the first connecting assembly 46 can be detachably connected, for example, they can be connected together by bolts or the like.

[0068] like Figure 5 and Figure 6As shown, in one embodiment, the first connecting component 46 includes a first connecting member 461, a second connecting member 462, and an elastic member 463; the first connecting member 461 is connected to the first driving component 45; the second connecting member 462 is connected to the first connecting member 461 and the scraper 43, and is capable of reciprocating relative to the first connecting member 461 in a first direction; the elastic member 463 is disposed between the first connecting member 461 and the second connecting member 462, and is capable of elastic deformation when the second connecting member 462 moves away from the fixture 1 located at the second work station in the first direction.

[0069] The elastic extension and contraction of the first connecting component 46 includes the elastic stretching of the first connecting component 46 and the elastic contraction of the first connecting component 46.

[0070] When the scraper 43 presses the key along the first direction, it receives an upward reaction force from the key. This force is transmitted to the elastic element 463 through the second connector 462, causing the elastic element 463 to elastically deform. At this time, the first connecting assembly 46 can elastically contract. Subsequently, when the scraper 43 moves away from the key along the first direction, the elastic force of the elastic element 463 can reset it along the first direction, thereby achieving the elastic extension of the first connecting assembly 46.

[0071] like Figures 5 to 7 As shown, in one embodiment, the second connector 462 includes a first connecting portion 464. One of the first connector 461 and the first connecting portion 464 is provided with a connecting hole 465 extending in a first direction, and the other is provided with a connecting post 466, which is located inside the connecting hole 465. An elastic member 463 is located inside the connecting hole 465, and in the first direction, both ends of the elastic member 463 abut against the connecting post 466 and the first connecting portion 464, respectively.

[0072] Installing the elastic element 463 in the connecting hole 465 facilitates its installation. Simultaneously, the wall of the connecting hole 465 can limit the deformation direction of the elastic element 463 and the relative movement of the first connecting element 461 and the second connecting element 462 along the first direction, thereby ensuring the deburring effect of the scraper 43.

[0073] like Figure 4 , Figure 6 as well as Figure 8 As shown, in one embodiment, the second connector 462 further includes a second connector 467; the first connector 461 has a first limiting structure 468; the second connector 467 connects to the first connector 464 and has a second limiting structure 469; when the first connector 461 moves away from the fixture 1 located at the second work station along the first direction, the first limiting structure 468 can abut against the second limiting structure 469, so as to drive the first connector 464 and the second connector 467 away from the fixture 1 located at the second work station.

[0074] The first connecting part 464 and the second connecting part 467 are detachably connected, for example, they can be connected together by bolts or other connecting parts.

[0075] like Figure 6 As shown, in one embodiment, the first connector 461 includes a connecting post 466, and the first limiting structure 468 is a flange structure disposed on the side of the connecting post 466. The flange structure is located at the middle position of the connecting post 466. The lower end of the connecting post 466 extends into the connecting hole 465, and the upper end of the connecting post 466 is connected to the first driving assembly 45. The connecting post 466 may be a cylindrical structure.

[0076] In addition, such as Figure 8 As shown, the second connecting part 467 includes a first connecting plate 470 and a second connecting plate 471. The first connecting plate 470 and the second connecting plate 471 are connected to form an L-shaped structure. The first connecting plate 470 is connected to the first connecting part 464. The second limiting structure 469 is the second connecting plate 471. In addition, the second connecting plate 471 is provided with a limiting groove, and the limiting groove penetrates the second connecting plate 471 along the first direction. The second connecting plate 471 is located above the flange structure, and the connecting post 466 is located in the limiting groove.

[0077] In one embodiment, initially, the elastic element 463 may be in a compressed state. Under the elastic force of the elastic element 463, the first limiting structure 468 can abut against the second connecting plate 471. Alternatively, the elastic element 463 may be a coil spring or the like.

[0078] like Figure 4 , Figure 7 as well as Figure 9 As shown, in one embodiment, the first drive module 41 further includes a second connecting component 48, which is connected to the first support component 44. The first connecting portion 464 has a first guide structure 472, and the second connecting component 48 has a second guide structure 481. The first guide structure 472 and the second guide structure 481 cooperate to guide the movement of the first connecting portion 464 along a first direction. This makes the movement of the first connecting portion 464 along the first direction more stable, thereby ensuring the deburring effect of the scraper 43.

[0079] In one embodiment, the second connecting component 48 includes a connecting block 482, and a second guiding structure 481 is disposed on the connecting block 482.

[0080] In one embodiment, the first guide structure 472 may be a guide post, and the second guide structure 481 may be a guide hole extending along a first direction, with the guide post located within the guide hole. Furthermore, the guide hole extends through the second connecting component 48 (specifically, through the connecting block 482) along the first direction, and the guide post can extend from the end of the guide hole near the fixture 1 located at the second workstation (i.e., the lower end of the guide hole) of the second connecting component 48. Additionally, the first connecting portion 464 itself is a columnar structure, with a portion of the first connecting portion 464 serving as the guide post, or the entire first connecting portion 464 itself being a guide post.

[0081] like Figure 9 As shown, in one embodiment, the guide hole forms an opening (defined as a clearance opening 483) on the outer side of the second connecting assembly 48 in the radial direction of the guide hole. The guide post protrudes from the clearance opening 483 to connect to the second guide portion at the clearance opening 483. Specifically, the guide post connects to the first connecting plate 470 of the second guide portion.

[0082] In addition, the clearance 483 extends through the second connecting component 48 along the first direction, that is, the clearance 483 extends from one end of the guide hole to the other end of the guide hole.

[0083] In one embodiment, the guide hole is a circular hole, which is made into an arc groove by the provision of the clearance opening 483. Furthermore, the width of the clearance opening 483 is smaller than the diameter of the guide hole. In this embodiment, the guide post can be a cylindrical structure.

[0084] like Figure 7 As shown, in one embodiment, the cylindrical structure is provided with a flat part 473, and the first connecting plate 470 is connected to the flat part 473, which facilitates the connection and cooperation between the guide post and the first connecting plate 470.

[0085] Furthermore, when the guide post rotates around its own axis within the guide hole, the second connecting component 48 can abut against the first connecting component 46 to prevent the guide post from continuing to rotate.

[0086] Specifically, when the guide post rotates around its own axis within the guide hole, the first connecting plate 470 can abut against the second connecting assembly 48. At this time, the width of the clearance opening 483 can be smaller than the width of the first connecting plate 470.

[0087] In one embodiment, the width direction of the clearance opening 483 is parallel to the width of the first connecting plate 470, and may be perpendicular to the first direction and the second direction.

[0088] In one embodiment, after assembly, the first connecting plate 470 can be the surface on both sides of the contact clearance opening 483, thus preventing the guide post from rotating around its own axis. Both surfaces on both sides of the clearance opening 483 can be planar. Alternatively, the surfaces on both sides of the clearance opening 483 can belong to the same surface, with the clearance opening 483 located on that surface, thus dividing the surface into two surfaces.

[0089] like Figure 7 As shown, in one embodiment, the scraper 43 is mounted on the flat part 473. The flat part 473 is provided with a mounting groove 474, and the scraper 43 is mounted in the mounting groove 474. The mounting groove 474 can restrict the installation position of the scraper 43.

[0090] In addition, the mounting groove 474 extends to the lower end face of the first connecting portion 464, and the scraper 43 extends out of the mounting groove 474 from the lower end face of the first connecting portion 464, and the part of the scraper 43 extending out of the mounting groove 474 is used for deburring.

[0091] In one embodiment, the first support component 44 further includes a fourth support plate 444, which is connected to the third support plate 443 and located below the third support plate 443; a connecting block 482 is connected to the fourth support plate 444 and located below the fourth support plate 444.

[0092] like Figure 4 As shown, in one embodiment, there are multiple first connecting components 46 and scrapers 43. The fixture 1 includes multiple clamps, each used to hold a key. The first connecting components 46, scrapers 43, and clamps correspond one-to-one. The scraper 43 is connected to its corresponding first connecting component 46 and is used to deburr the key on its corresponding clamp. "Multiple" means two or more. The meaning of the term "multiple" is the same in all embodiments and will not be repeated hereafter.

[0093] This allows for the deburring of the first teeth of multiple keys at once, thereby improving production efficiency.

[0094] Multiple fixtures 1 can belong to the same fixture group, and the entire key-making machine 10 can have multiple fixture groups. When one fixture group is moved to the second station, another fixture group is moved to the first station. In this way, while deburring and flipping the keys at the second station, the first teeth of the keys on the fixture group at the first station can also be machined, thereby further improving production efficiency.

[0095] like Figure 3As shown, in one embodiment, the flipping device 5 is connected to the second drive module 42. The second drive module 42 is used to drive the flipping device 5 to reciprocate along the second direction, so that the flipping device 5 can switch between a first position close to the fixture 1 of the second workstation and a second position away from the fixture 1 of the second workstation. When the flipping device 5 is in the first position, it can grab the key on the fixture 1 of the second workstation so as to drive the key grabbed by it to move to the second position. When the flipping device 5 is in the second position, it can drive the key grabbed by it to flip over.

[0096] In this embodiment, the second drive module 42 can drive the scraper 43 to reciprocate along the second direction and also drive the flipping device 5 to reciprocate along the second direction. This reduces the need for a corresponding power source, which not only lowers the cost of the key machine 10 but also makes the key machine 10 more integrated.

[0097] like Figure 4 As shown, in one embodiment, the first driving component 45 includes a first driving member 451 and a first guiding mechanism 452; the first driving member 451 is connected to the first connecting component 46 and is used to drive the first connecting component 46 to reciprocate along a first direction; the first guiding mechanism 452 is used to guide the movement of the first connecting component 46 along the first direction.

[0098] The first driving component 451 includes a linear cylinder and a transition plate 453. The cylinder body of the linear cylinder is connected to the first support assembly 44, and the piston rod of the linear cylinder is connected to the transition plate 453. The first connecting assembly 46 is connected to the transition plate 453. Specifically, the first connecting member 461 is connected to the transition plate 453.

[0099] In one embodiment, the first guiding mechanism 452 includes a guide rod connected to the transition plate 453 and cooperating with a guide hole on the first support assembly 44 to guide the movement of the first connector 461 along a first direction.

[0100] like Figure 3 As shown, the first support assembly 44 includes a first support plate 441, a second support plate 442, and a third support plate 443. The first support plate 441 and the second support plate 442 are both connected to the second drive module 42 and are spaced apart. The third support plate 443 connects the first support plate 441 and the second support plate 442. In the second direction, the third support plate 443 protrudes from the end of the first support plate 441 near the fixture 1 (which is located at the second workstation), and the third support plate 443 also protrudes from the end of the second support plate 442 near the fixture 1 (which is located at the second workstation).

[0101] The first drive assembly 45 is connected to the third support plate 443, and in the second direction, the first drive assembly 45 is located between the first support plate 441 and the fixture 1 (the fixture 1 is located at the second work station), and between the second support plate 442 and the fixture 1 (the fixture 1 is located at the second work station).

[0102] The flipping device 5 is connected to the first support assembly 44, which is specifically connected to the first support plate 441 and the second support plate 442, and is located between the first support plate 441 and the second support plate 442.

[0103] In addition, the flipping device 5 is located below the third support plate 443, and the second drive module 42 is located below the flipping device 5.

[0104] like Figure 3 As shown, in one embodiment, the flipping device 5 includes a flipping clamping module 51 and a flipping drive module 52. The flipping clamping module 51 is used to clamp a key on the fixture 1 located at the second station. The flipping drive module 52 is connected to the flipping clamping module 51 and is used to drive the flipping clamping module 51 to rotate, so as to flip the key held therein. Typically, the flipping drive module 52 drives the flipping clamping module 51 to rotate 180 degrees. That is, when processing the key, corresponding teeth need to be machined on its two opposite surfaces.

[0105] The flip-grip module 51 includes a gripping block and a gripping drive component. In a second direction, the gripping block has a receiving hole on its surface near the fixture 1, which is used to insert a portion of a key from the fixture 1. The gripping drive component 13 is connected to the gripping block and can press the key within the receiving hole against the hole wall to clamp and fix the key. Specifically, the gripping drive component 13 may include a diaphragm cylinder, at least a portion of which is located within the receiving hole. During operation, the diaphragm cylinder can press the key within the receiving hole against the hole wall. Of course, the diaphragm cylinder can also reverse its movement to release the key from the receiving hole.

[0106] Alternatively, the end of the key is usually inserted into the receiving hole.

[0107] It should be understood that the flipping device 5 can be an existing technology. In the existing technology, the flipping device 5 usually needs to be driven by a corresponding power source (similar to the second drive module 42) to reciprocate along the second direction. The flipping device 5 and the power source that it works with are defined as a flipping unit. Compared with this method, the setting of this embodiment is equivalent to adding a first drive module 41 and a scraper 43 to the existing flipping unit.

[0108] like Figure 1As shown, in one embodiment, the key-making machine 10 further includes a second processing device 7 and a second deburring device 8; the conveying device 2 is also used to drive the fixture 1 to move to the third and fourth workstations; the second processing device 7 is used to process the second teeth of the key located on the fixture 1 at the third workstation and flipped by the flipping device 5; the second deburring device 8 is used to deburr the second teeth of the key located on the fixture 1 at the fourth workstation. This allows for the processing of the teeth on the reverse side of the key and the deburring of the reverse teeth.

[0109] The second processing device 7 is also an existing design, and will not be described in detail in this embodiment.

[0110] In addition, the second deburring device 8 and the first deburring device 4 can have the same structure, which will not be repeated here in this embodiment.

[0111] like Figure 1 As shown, in one embodiment, the key-making machine 10 further includes a feeding device 9, which is used to remove keys that have been deburred by the second deburring device 8 from the fixture 1 located at the fourth station. This can improve production efficiency.

[0112] The unloading device 9 includes an unloading drive module and a pusher. The unloading drive module can drive the pusher to move, so that the pusher can push the key on the fixture 1 to move and push it out of the fixture 1. Moreover, the unloading drive module can be a linear cylinder, and the pusher can be a rubber block, etc.

[0113] In addition, the feeding device 9 is also an existing design, and will not be described in detail in this embodiment.

[0114] In addition, when the first station has a fixture set, the second, third, and fourth stations also have fixture sets to improve processing efficiency.

[0115] In one embodiment, the first drive module includes a linear cylinder and a guide mechanism. The linear cylinder is used to drive the scraper to reciprocate linearly along a second direction, and the guide mechanism is used to guide the movement of the scraper along the second direction.

[0116] like Figure 1 and Figure 3 As shown, in one embodiment, the key-operating device 10 further includes a pressing device 20 connected to the first support assembly 44, specifically connected to the third support plate 443. The pressing device is used to press the key onto the fixture 1 along a first direction.

[0117] After deburring the first tooth, the first deburring device 4 resets; then, the pressing device 20 actuates to press the key onto the fixture 1; then, the fixture 1 releases the key; then, the flipping device 5 clamps the key; then, the pressing device 20 resets and releases the key; then, the flipping device 5 flips the key (previously, the second drive module 42 first drives the flipping device 5 to move to the second position). This avoids interference between the flipping device 5 and the fixture 1 when it moves toward the first position. Of course, in other embodiments, the pressing device 20 may be omitted, and the fixture 1 releases the key after the flipping device 5 clamps it.

[0118] The pressing device 20 includes a pressing drive and a pressing member. The pressing drive is connected to the third support plate 443, and the pressing member is connected to the pressing drive. The pressing drive can drive the pressing member to reciprocate along a first direction. When the pressing member approaches the fixture 1 along the first direction, it can press the key onto the fixture 1. Alternatively, the pressing drive can be a linear cylinder, and the pressing member can be a rubber block, etc.

[0119] In addition, in the second direction, the pressing device 20 may be located between the first drive module 41 and the first support plate 441, and between the first drive module 41 and the second support plate 442.

[0120] like Figure 1 As shown, in one embodiment, the key-operating machine 10 further includes a feeding device 30 located at a fifth station. The conveying device can transport the fixture 1 to the fifth station, and the feeding device can place the key on the fixture located at the fifth station. Subsequently, the conveying device can transport the fixture from the fifth station to the first station. Furthermore, in one operation, the conveying device can transport the fixture from the fifth station to the first station, the fixture from the first station to the second station, the fixture from the second station to the third station, the fixture from the third station to the fourth station, and the fixture from the fourth station to the fifth station.

[0121] like Figure 1 As shown, in one embodiment, the key machine 10 also has a worktable 40, on which the aforementioned fixture 1, conveying device 2, first processing device 3, first deburring device 4, flipping device 5, second processing device 7, second deburring device 8, unloading device 9, and loading device 30 are all installed.

[0122] It should be understood that the above-mentioned settings can also be replaced in other ways, such as:

[0123] In other embodiments, the key-making machine 10 includes a fixture 1, a conveying device 2, a processing unit, a second deburring device 8, and a unloading device 9; the fixture 1 is connected to the conveying device 2 and is used to hold keys; the conveying device 2 is used to drive the fixture 1 to move to the processing station and the unloading station; the processing unit is used to process the teeth of the keys on the fixture 1 located at the processing station; the second deburring device 8 is used to deburr the teeth of the keys on the fixture 1 located at the unloading station; the unloading device 9 is used to remove the keys that have been deburred by the second deburring device 8 from the fixture 1 located at the unloading station.

[0124] In this embodiment, the processing unit includes the first processing device 3 and the second processing device 7 described in the previous embodiment, the processing stations include the first station and the third station described above, and the unloading station is the fourth station described above. The difference between this embodiment and the previous embodiment is that the first deburring device 4 is not provided in this embodiment. Apart from this, all other related settings in this embodiment can be the same as those in the previous embodiments.

[0125] In other embodiments, only the second station may have a first deburring device 4, without a second deburring device 8.

[0126] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0127] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model, and should all be included within the protection scope of this utility model.
