[0037] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example
[0038] like Figure 1-11 The feed mechanism 50 and tapping machine shown are primarily composed of a processing mechanism 20 (for tapping and drilling), a feed mechanism 50, a material return mechanism 40, a material pusher mechanism 30 cooperating with the feed mechanism 50, a main processing block 10, and a plate frame 60 supporting each mechanism. A feed vibration plate (not shown) and a feed channel 70 are also connected to the main processing block 10. One end of the feed channel 70 is connected to the feed vibration plate, and the other end is connected to the main processing block 10. A linear vibrator is provided on the side of the feed channel 70 to drive the material toward the feed mechanism 50.
[0039] Reference Figure 1 The plate rack 60 mainly includes a large plate 601, a small plate 602, and a support plate 603 for installing the overall mechanism. Among them, the processing mechanism 20 is installed on the large plate 601 through fasteners, and the feeding mechanism 50 is installed on the small plate 602 through fasteners, and then installed on the large plate 601 through the small plate 602. The support plate 603 is mainly used to install the pushing mechanism 30, the returning mechanism 40 and the main processing block 10.
[0040] Specifically, the support plate 603 is disposed above the small plate 602, and a material return chute 71 is provided between the support plate 603 and the small plate 602. The material return chute 71 is obliquely disposed on the small plate 602, with its higher end disposed below the main processing block 10 and its lower end extending downward from the processing mechanism 20. It should be noted that the highest end of the material return chute 71 may also be disposed above the main processing block 10, as long as the material can fall from the main processing block 10 into the material return chute 71.
[0041] Reference Figure 2-5 , Figure 11 The feeding mechanism 50 will be described in detail.
[0042] The middle part of the main processing block 10 is provided with a transverse groove 103, four longitudinal first grooves 105, four longitudinal second grooves 106 and a clamping slot 101 for clamping the feed channel 70. In particular, a sensor 102 for detecting whether the material is in place is also embedded in the main processing block 10.
[0043] The main processing block 10 is a rectangular structure as a whole. The transverse direction is a horizontal direction parallel to the longer side of the main processing block 10 , and the longitudinal direction is perpendicular to the transverse direction, and both are on the same horizontal plane.
[0044] The first groove 105 and the second groove 106 are aligned with each other and correspond one to one. The first groove 105 and the second groove 106 are respectively arranged on both sides of the groove 103, wherein the first groove 105 is used for the pushing mechanism 30 to move and place, and the second groove 106 is used for the returning mechanism 40 to move and place.
[0045] The feed channel 70 is arranged on the outer side of the main processing block 10, and the sensor 102 is arranged on the opposite side of the feed channel 70 through the clamping block 107, that is, on the other side of the groove 103. When the material is transported from the feed channel 70 to the feeding mechanism 50, the material arrival indication is performed.
[0046] The feed mechanism 50 includes a displacement module 501 and a feed block 504. The displacement module 501 is composed of a fixed member 503 and a movable member 502. One end of the feed block 504 is bolted to the top of the movable member 502. It should be noted that the displacement module 501 is conventional, and it primarily uses a precision lead screw motor to drive the movable member 502 to slide horizontally on the fixed member 503.
[0047] Specifically, four limiting grooves 5041 corresponding to the first groove 105 and the second groove 106 are provided on the other side of the feed block 504. The spacing between the limiting grooves 5041 is the same as the spacing between the first groove 105 and the second groove 106, that is, the spacing d between the first groove 105 and the adjacent first groove 105 is equal to the spacing f between the second groove 106 and the adjacent second groove 106 is equal to the spacing g between the limiting groove 5041 and the adjacent limiting groove 5041.
[0048] The number of the first grooves 105 and the second grooves 106 corresponds to the number of the limiting grooves 5041 , and the ends of the first grooves 105 and the second grooves 106 close to the groove 103 are both connected to the groove 103 .
[0049] The feed block 504 moves horizontally in the groove 103 under the drive of the moving member 502. Figure 11 The limiting groove 5041 on the feed block 504 shown includes a first groove 5042 on one side near the displacement member and a fourth groove 5043 on one end away from the displacement member. When the feeding mechanism 50 of the tapping machine is in the initial state, the first groove 5042 coincides with the end of the feed channel 70. The material moves into the first groove 5042. The sensor 102 detects the material's presence and transmits a signal to the control system (not shown). The displacement module 501 then drives the feed block 504 backward so that the limiting groove 5041 adjacent to the first groove 5042 coincides with the end of the feed channel 70.
[0050] This process is repeated until the material enters the fourth slot 5043 and is detected by the sensor 102 , and then the displacement module 501 drives the feed block 504 to move forward, so that the limiting slot 5041 and the corresponding first slot 105 and second slot 106 coincide with each other.
[0051] Specifically, the material is pushed into the second channel 106 by the pushing mechanism 30 and abuts against one end of the material return mechanism 40. At this time, the material should be below the processing structure, that is, the processing mechanism 20 can directly move down to perform tapping and drilling. After processing is completed, the material is pushed into the groove 103 by the material return mechanism 40.
[0052] Preferably, a tube support plate 603 and a through groove 104 of the groove 103 are provided at the bottom of the groove 103 , and the processed workpiece is pushed into the through groove 104 by the material return mechanism 40 and discharged along the material return groove 71 .
[0053] Preferably, the feed mechanism 50 is positioned on the left or right side of the main processing block 10. A fixing block 505 is also provided on the side of the main processing block 10 to prevent the feed block 504 from shifting. This fixing block 505 is L-shaped and connected to the main processing block 10 via bolts. The two fixing blocks 505 are positioned back-to-back with a gap between them. The width of this gap is greater than or equal to the width of the feed block 504.
[0054] like Figure 6 As shown, in this embodiment, the left and right sides of the main processing block 10 are each provided with four first grooves 105, two second grooves 106, a slot 101, and a sensor 102. This means that the left and right sides of the main processing block 10 are mirror-symmetrical. Depending on actual needs, only four first grooves 105 and two second grooves 106 may be provided on the main processing block 10. In this embodiment, the main processing block 10 is simply composed of two sets of processing units.
[0055] That is, it is sufficient as long as the main processing block 10 is provided with a plurality of first grooves 105 , a second groove 106 , a card slot 101 for connecting the material feeding channel 70 and a sensor 102 .
[0056] Reference Figure 6-10 The material pushing and withdrawing mechanism 40 will be described in detail.
[0057] Furthermore, the material return mechanism 40 is provided with an adjustment assembly 402. The material return mechanism 40 comprises a fixing plate 404 connected to the support plate 603, a connecting block 403, and a cylinder. The cylinder is used to drive the connecting block 403 to move forward and backward. A transfer block 405 is provided between the connecting block 403 and the cylinder. One end of the transfer block 405 is plugged or threadedly connected to the telescopic end of the cylinder, and the other end is provided with an extension portion extending outward to form a "convex"-shaped block 107.
[0058] The connecting block 403 is provided with a connecting groove 4033 that cooperates with the clamping block 107. The connecting groove 4033 is also a "convex"-shaped structure, that is, an opening is provided on the side of the connecting block 403. The connecting block 403 is also provided with four "convex"-shaped cavities 4032, which are connected to the top block 401 through the cavities 4032. The end of the top block 401 is provided with a stopper 4011 that cooperates with the cavities 4032. The stopper 4011 is a "convex"-shaped structure or a "earth"-shaped structure. That is, according to actual needs, the side of the top block 401 can be provided with one or two protrusions 4012 extending to both sides.
[0059] The top block 401 is connected to the cavity 4032 via a stopper 4011. The width a inside the cavity 4032 is greater than the width b of the protrusion 4012, forming an adjustment area H. The adjustment assembly 402 includes an adjustment rod 4021 and a stop nut 4022 that cooperates with the adjustment rod 4021. External threads are provided on the upper portion or upper mid-portion of the adjustment rod 4021. A cavity 4031 is formed through the sidewall of each cavity 4032. A through hole 4041 is provided in the fixing plate 404, coinciding with the cavity 4031.
[0060] Specifically, cavity 4031 is provided with a connecting thread that mates with the external thread of adjustment rod 4021. Adjustment rod 4021 passes through through-hole 4041 and cavity 4031, with one end abutting against top block 401. Adjustment rod 4021 is limited in position by the connecting thread and the internal thread of limit nut 4022. Rotating limit nut 4022 adjusts the length of adjustment rod 4021 extending into adjustment area H, thereby fine-tuning the depth of top block 401. Compared to the overall adjustment method used in the prior art, single-station adjustment not only effectively prevents displacement of connection block 403, but also allows for fine-tuning at each station, making it highly reliable.
[0061] Preferably, a guide rod 4034 extending backward is provided on the side where the connecting block 403 abuts the fixing plate 404, and a guide groove 4042 cooperating with the guide rod 4034 is provided on the fixing plate 404. In this embodiment, the number of the guide groove 4042 and the guide rod 4034 are both two, and the two guide rods 4034 and the guide groove 4042 are respectively arranged on both sides of the adapter block 405.
[0062] A guide sleeve 4035 is further provided in the guide groove 4042 for stabilizing the guide rod 4034 . The guide sleeve 4035 is made of elastic material, that is, there is an interference fit between the guide rod 4034 and the guide sleeve 4035 .
[0063] It should be noted that, according to actual needs, the number of the first channel 105, the second channel 106 and the limiting groove 5041 is not limited to four. As long as space and stability allow, they can be extended indefinitely, that is, multiple stations can perform processing simultaneously. As long as the distance between the processing mechanism 20 and the feed channel allows, the feeding logic of the feed block 504 can also be completely opposite to that of the present embodiment, that is, the material is first transported to the fourth trough 5043, the moving member 502 drives the feed block 504 forward, and after the material is transported to a limiting groove 5041 adjacent to the fourth trough 5043, the moving member 502 continues to move forward until the limiting grooves 5041 on the feed trough are all filled with material. Finally, the mobile module moves the feed block 504 to the position corresponding to the first channel 105 and the second channel 106 to continue processing.
[0064] The embodiments described above are merely descriptions of preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Any modifications and improvements made to the technical solution of the present invention by a person of ordinary skill in the art without departing from the design concept of the present invention shall fall within the scope of protection of the present invention. The technical content for which protection is sought in the present invention is fully set forth in the claims.
