Description

Technical Field

[0001] The invention belongs to the technical field of fastener processing, and in particular relates to a thread rolling and feeding device. Background Art

[0002] Fasteners are a type of mechanical parts used for fastening connections and are extremely widely used. They usually include bolts, studs, screws, nuts and other types. In the production process of fasteners, loading devices are often required to transport the fasteners. The loading device can automatically transport the fasteners from one process to the next for subsequent assembly, weighing and other processes.

[0003] In the processing of fasteners, a thread rolling machine is needed. The thread rolling machine is a processing equipment for the outer surface of cylindrical workpieces. It is composed of two identical thread rolling surfaces with the same thread shape and helix angle as the bolt thread. When the thread rolling plates move against each other, the bolt blank between the two thread rolling plates is threaded. The thread rolling plates complete the processing of a bolt thread once they go back and forth. The speed is quite high. Corresponding to the thread rolling machine, it is necessary to equip the feeding and discharging device for the fasteners to feed the thread rolling machine.

[0004] For example, a Chinese patent with application number CN202420066280.5 discloses a screw pushing mechanism for a thread rolling plate with broken teeth at the tail end, comprising a thread rolling machine body and bolts, a lower hopper, and support rods fixed on both sides, the bottom of the support rods being placed on the ground; a discharge plate connected to the lower hopper, and a pressure plate connected to the middle top of the discharge plate and the lower hopper; a vertical device installed at the end of the discharge plate away from the lower hopper; a fixed table installed at the end of the thread rolling machine body away from the lower hopper; the thread rolling plates are installed on both sides of the fixed table; and a pushing device is installed at the end of the vertical device away from the discharge plate.

[0005] With further research by the applicant, it was found that the existing thread rolling plate pushing structure mainly drives the push rod to push through a motor or a cylinder. The motor or the cylinder controls the pushing rhythm of the push rod according to the reciprocating rhythm of the active thread rolling plate on the thread rolling machine. When pushing the fasteners, there is a certain room for improvement in the pushing efficiency. Among them, the ready pushing position of the fasteners before being pushed is always random, which affects the accuracy of the coordination with the pushing components, resulting in frequent empty pushing and oblique pushing of fasteners, which reduces the efficiency and quality of the thread rolling process. Summary of the invention

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A thread rolling and feeding device, comprising:

[0008] The machine body is provided with a linkage assembly and a discharge guide rail for conveying fasteners;

[0009] A pusher seat is arranged at the front end side of the discharge guide rail, and a guide cavity extending toward one side of the discharge guide rail is opened in the pusher seat;

[0010] A pusher shaft is placed in the guide cavity;

[0011] The pusher body is disposed on the side of the pusher seat and connected to the pusher shaft;

[0012] A material dividing needle, slidably connected to the material pushing knife seat;

[0013] A swinging member is rotatably connected to the pusher seat, and two ends of the swinging member are respectively connected to the pusher shaft and the linkage assembly;

[0014] A rotating shell is arranged outside the machine body, a material guide hopper is connected to the rotating shell, a material receiving plate and a plurality of material guide blades surrounding the outer periphery of the material receiving plate are arranged in the middle of the rotating shell, and the material guide blades are connected to the inner wall of the rotating shell; and

[0015] A driving member, used for driving the rotating shell to rotate;

[0016] The discharge end of the discharge guide rail has a notch, and the end of the material distribution needle can match the notch.

[0017] Furthermore, the linkage assembly is driven by the power member to force the swing member to rotate, and drives the push knife shaft to reciprocate along the guide cavity, and the push knife body and the dividing needle move in opposite directions. The linkage assembly includes an eccentric cam driven by the power member, a swing body cooperating with the eccentric cam, and a hinge rod for connecting the swing member and the swing body.

[0018] Furthermore, the swinging member is connected to a rotating shaft, and the pusher seat has a toggle plate rotatably connected thereto, the head of the toggle plate cooperates with the outer side of the rotating shaft, and the tail of the toggle plate cooperates with the dividing needle.

[0019] Furthermore, the guide hopper is connected with a discharge wheel and a discharge baffle.

[0020] Furthermore, a supporting angle iron is connected to the bottom of the guide hopper.

[0021] Furthermore, it also includes a feed hopper, which is connected to the side of the guide hopper.

[0022] Furthermore, a mounting groove conforming to the material dividing needle is provided at the upper end of the material pushing knife seat.

[0023] Furthermore, the discharge guide rail includes a left rib and a right rib which are arranged in parallel and extend into the rotating shell, and there is a gap between the left rib and the right rib.

[0024] Furthermore, the material receiving plate includes a material plate portion and a material plate portion connected to two sides of the material discharge guide rail, and the material plate portion and the material plate portion extend along the length direction of the material discharge guide rail.

[0027] The device can push the fasteners into the thread rolling mechanism in an orderly, uninterrupted and rapid manner. The various parts of the discharger adopt an ingenious mechanical linkage structure and can share the same power source to realize the blocking / discharging and pushing processes of the fasteners. Due to the use of a pusher seat, a swinging part, a pusher shaft and the like, the above-mentioned blocking / discharging and pushing processes can maintain a synchronous rhythm, thereby avoiding the occurrence of empty pushing or oblique pushing of fasteners.

[0028] Among them, the loader adopts a shell rotation method to lift the concentrated miscellaneous fastener materials to the top of the discharge guide rail through the rotation of the guide blades, and then falls to the receiving plate due to gravity. Compared with the existing discharge method, it can reduce the probability of backlog and blockage of fasteners during the discharge process, and has the advantage of improving the feeding and discharge effect.

DETAILED DESCRIPTION

[0041] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0042] Among them, the drawings are only used for illustrative purposes, showing only schematic diagrams rather than actual drawings, and should not be understood as limitations on this patent; in order to better illustrate the embodiments of the present invention, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted, and the same or similar numbers in the drawings of the embodiments of the present invention correspond to the same or similar parts; in the description of the present invention, it should be understood that the terms "upper", "lower", "left", "right", "inner", "outer", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation.

[0043] like Figure 1 - Fig.10 As shown, a thread rolling and feeding device of the present invention comprises a machine body 1, a pusher seat 13, a pusher shaft 140, a pusher body 141, a dividing needle 142, a swinging member 143 and a linkage assembly 15;

[0044] The machine body 1 is provided with a linkage assembly 15 and a discharge guide rail 12 for conveying fasteners;

[0045] The pusher seat 13 is arranged on the side of the discharge guide rail 12, and a guide cavity 130 extending toward one side of the discharge guide rail 12 is opened in the pusher seat 13;

[0046] The pusher shaft 140 is placed in the guide cavity 130, the pusher body 141 is placed on the side of the pusher seat 13 and connected to the pusher shaft 140, and the dividing needle 142 is slidably connected to the pusher seat 13;

[0047] The swing member 143 is rotatably connected to the pusher seat 13, and both ends of the swing member 143 are respectively connected to the pusher shaft 140 and the linkage assembly 15;

[0048] The linkage assembly 15 is driven by the power member to force the swing member 143 to rotate, and drives the pusher shaft 140 to reciprocate along the guide cavity 130, and the pusher body 141 and the dividing needle 142 move in opposite directions.

[0049] The device can push the fasteners into the thread rolling mechanism in an orderly, uninterrupted and rapid manner. The various components of the discharger adopt an ingenious mechanical linkage structure and can share the same power source to realize the blocking / discharging and pushing processes of the fasteners. Due to the use of the pusher seat 13, the swing member 143, the pusher shaft 140 and the like, the above-mentioned blocking / discharging and pushing processes can maintain a synchronous rhythm, thereby avoiding the occurrence of empty pushing or oblique pushing of fasteners.

[0050] The fasteners in this embodiment are specifically bolts and screws, and their sizes are not specifically limited as long as they can be hung upside down on the guide rail.

[0051] In the discharge guide rail 12, an existing bolt feeding device is used to introduce batches of bolts onto the discharge guide rail 12. The dividing needle 142 controls the passage of the bolts, and the feeding of the bolts to the thread rolling mechanism is realized through the pusher cutter body 141.

[0052] Specifically, Figure 2 , Figure 3 As shown, the linkage assembly 15 includes an eccentric cam 150 driven by a power member (not shown), a swinging body 151 matched with the eccentric cam 150, and a hinge rod 152 for connecting the swinging body 151 and the swinging body 151. The power member is installed on the machine body 1, and the power member can be a motor, and its output shaft is connected to the eccentric cam 150.

[0053] When the end of the pusher body 141 moves close to one side of the discharge guide rail 12, the dividing needle 142 needs to move in the opposite direction to the pusher body 141 so that the dividing needle 142 can retreat and allow the fasteners in the gap 122 of the discharge guide to continue moving forward without being blocked by the dividing needle 142. The feeding is completed by the pusher body 141, and the thread rolling operation of the fasteners is completed by the thread rolling mechanism installed on the machine body 1.

[0054] Specifically, the opposite movements of the material dividing needle 142 and the material pushing knife body 141 are completed by the following schemes:

[0055] The swinging member 143 is connected with a rotating shaft 160 , and the pusher seat 13 is provided with a toggle piece 161 rotatably connected thereto. The head of the toggle piece 161 matches with the outer side of the rotating shaft 160 , and the tail of the toggle piece 161 matches with the material dividing needle 142 .

[0056] Under the action of the linkage mechanism, the swing member 143 causes the rotating shaft 160 connected to the side arm of the swing member 143 to deflect together, wherein the side arm of the swing member 143 drives the pusher shaft 140 and the pusher body 141 to move along the setting direction of the guide cavity 130, and the deflected rotating shaft 160 squeezes the head of the toggle piece 161, so that the tail of the toggle piece 161 reversely squeezes and pushes the dividing needle 142.

[0057] The side of the pusher seat 13 has a notch 1300. The notch 1300 allows the pusher shaft 140 to be connected to the pusher shaft 140 while ensuring that the pusher body 141 is on the side of the pusher seat 13, and is driven together to push / feed the fasteners in the track back and forth.

[0058] Also includes feeders, such as Figure 7 , Figure 8 , Fig. 9 , Fig.10 As shown, the feeder includes a rotating shell 22 arranged outside the body 1, the rotating shell 22 is connected to the side of the guide hopper 21, a receiving plate and a plurality of groups of guiding blades 220 surrounding the outer periphery of the receiving plate are arranged in the middle of the rotating shell 22, and the guiding blades 220 are connected to the inner wall of the rotating shell 22;

[0059] The outer side of the rotating shell 22 is connected with a driving member 23, and the driving member 23 is used to drive the rotating shell 22 to rotate;

[0060] One end of the discharge guide rail 12 extends into the rotating shell 22 and is connected to the receiving plate;

[0061] The rotating shell 22 rotates under the action of the driving member 23 , and guides the material in the guide hopper 21 into the discharge guide rail 12 through the material receiving plate through the guide blades 220 , and is guided to the outside of the guide hopper 21 by the discharge guide rail 12 .

[0062] By rotating the rotating shell 22, the miscellaneous fastener materials that are concentrated are rotated and moved by the guide blades 220, lifted to the top of the discharge guide rail 12, and fall onto the receiving plate due to gravity. Compared with the current discharge method, the probability of fastener backlog and blockage during the discharge process can be reduced, which has the advantage of improving the feeding and discharge effects.

[0063] This loader method adopts automation and precise control, which effectively solves the problems of traditional manual loading, low efficiency and insufficient accuracy, brings significant improvement in production efficiency and cost savings, and improves product quality.

[0064] The material receiving plate includes a material plate portion 250 and a material plate portion 251 connected to two sides of the material discharge guide rail 12 . The material plate portion 250 and the material plate portion 251 extend along the length direction of the material discharge guide rail 12 .

[0065] The fasteners that fall randomly can be transported in the inclined direction of the discharge guide rail 12 under the action of the receiving plate and the baffle plate 252 so that the tail of the fasteners is directed toward the discharge guide rail 12 .

[0066] The first material plate 250 and the second material plate 251 are arranged obliquely, and a material blocking plate 252 is connected to the upper end of at least one of them.

[0067] Specifically, the discharge guide rail 12 includes a left rib 120 and a right rib 121 that are arranged in parallel, and a gap 122 is provided between the left rib 120 and the right rib 121 .

[0068] The discharge guide rail 12 is configured to have a left rib 120 and a right rib 121, and a gap 122 formed therebetween allows the fastener column to pass through, and the size of the gap 122 is smaller than the size of the fastener head. In this way, each fastener being transported is hung on the discharge guide rail 12 and slides downward along the discharge guide rail 12 in turn.

[0069] A discharge wheel 260 and a discharge baffle 261 are connected to the guide hopper 21. By pushing the discharge baffle 261, the material can be discharged according to production needs.

[0070] like Figure 8 , Fig. 9 As shown, a support angle iron 210 is connected to the bottom of the guide hopper 21, and other external devices, such as a heading machine or a machine body 1, can be connected through the support angle iron 210.

[0071] In addition, a feed hopper 27 is connected to the side of the guide hopper 21, and the feed hopper 27 is connected to the upper end of the side of the guide hopper 21. The opening of the feed hopper 27 can face upward, and the operator can put a large amount of material into it from the opening. The feed point of the guide hopper 21 is connected to the feed hopper 27. Since the feed hopper 27 is arranged above the feed point of the guide hopper 21, the material enters and accumulates inside the guide hopper 21 under the action of its own weight. When the rotating shell 22 rotates, the material is continuously guided to the discharge guide rail 12.

[0072] In addition, a notch 123 is provided at the discharge end of the discharge guide rail 12 , and the end of the dividing needle 142 can be matched with the notch 123 .

[0073] When the end of the dividing needle 142 is located at the notch 123 , it can be blocked by the fastener on the discharging guide rail 12 , and then cooperate with the pushing knife body 141 to achieve the purpose of orderly discharging.

[0074] The upper end of the pusher seat 13 is provided with a mounting groove 131 which is shaped to match the material dividing needle 142. The material dividing needle 142 is Z-shaped.

[0075] In addition, a spring seat 132 is connected to the outer side of the pusher seat 13 , and the tail end of the material dividing needle 142 matches with the spring seat 132 .

[0076] A spring (not shown) is arranged between the tail of the dividing needle 142 and the spring seat 132. To prevent the dividing needle 142 from escaping from the pusher seat 13 during the reciprocating movement, a cover plate (not shown) can be arranged on the top of the pusher seat 13 to ensure the lateral movement of the dividing needle 142.

[0077] In addition, a thread rolling seat 17 is provided on the machine body 1. Figure 1 , Figure 2 As shown, the thread rolling seat 17 is located outside the pusher body 141. The thread rolling seat 17 is an accessory of the thread rolling mechanism, and the thread rolling mechanism (not shown) is fixedly mounted on the machine body 1 through the structure.

[0078] The end of the dividing needle 142 is located at the recess 123, which can be placed opposite to the fastener on the discharge guide rail 12 to block, and then cooperate with the pusher body 141 to achieve the purpose of orderly discharge. This structure has strong reliability and ensures the accuracy of fastener discharge / pushing. Cooperating with the thread rolling mechanism, it can achieve the purpose of quickly processing the fastener threads.

[0079] It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, which should also be regarded as the scope of protection of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent.
