Description

Technical Field

[0001] The utility model relates to the technical field of assembly feeding, in particular to a stud assembly feeding device. Background Art

[0002] With the development of mold technology, the production process of continuous stamping molds has become increasingly mature. The process of riveting rivets and stamping parts has evolved from the original method of first stamping, then manually installing rivets, and then stamping and riveting to a vibration plate that automatically feeds rivets into the mold. In a set of stamping continuous molds, the entire process of part stamping and rivet riveting is completed; after the process is improved, riveted parts can be produced using stamping continuous molds, eliminating the manual riveting process, realizing riveting automation, improving production efficiency, and improving product quality. However, most of the current vibration plates directly feed rivets into the mold through the feed track when feeding, and rivets are riveted on the mold when stamping; however, the above feeding method is prone to rivet offset problems during actual use, which in turn causes inaccurate position during riveting. In severe cases, it can also cause the rivet and the mold to get stuck, causing mold damage or equipment shutdown. Utility Model Content

[0003] The utility model provides a stud assembly feeding device, which can solve the technical problem that the existing rivets are easily offset after feeding, resulting in inaccurate riveting positions.

[0004] This application provides the following technical solutions:

[0005] A stud assembly feeding device comprises a feeding mechanism, a pushing mechanism and a feeding mechanism. The feeding mechanism is arranged on a feeding station. A guide hole for storing parts is arranged on the feeding mechanism. The guide hole is aligned with a discharge pipe of a vibration plate. The pushing mechanism is arranged at the discharge end of the feeding station through a mounting seat. The feeding mechanism is located directly below the pushing mechanism. A mounting hole for loading parts is arranged on the feeding mechanism. The pushing mechanism is used to vertically push the parts in the guide hole of the feeding mechanism into the mounting hole of the feeding mechanism. The feeding mechanism is used to transport the parts to a riveting station.

[0006] Technical principles and beneficial effects:

[0007] When assembling and loading parts such as rivets or studs, the parts are first discharged from the discharge pipe of the vibrating plate to the feeding mechanism. Since the feeding mechanism is provided with a guide hole, the parts fall into the guide hole from the outlet of the discharge pipe; then they are sent to the bottom of the pushing mechanism by the feeding mechanism. The pushing mechanism is used to push the parts on the feeding mechanism vertically into the mounting hole of the loading mechanism. Finally, the loading mechanism transports the parts to the riveting station.

[0008] In the above-mentioned feeding process, when the parts in the guide hole are offset, the pushing mechanism can be used to correct it, so that the parts in the guide hole are pushed vertically into the mounting hole, thereby ensuring that the parts are placed completely vertically in the mounting hole, and only when the feeding mechanism sends the parts to the riveting station can the parts be vertically riveted on the mold; compared with the prior art that directly discharges the parts to the riveting station through the vibration plate, the riveting accuracy of the parts and the assembly quality of the products are improved, and the problems of inaccurate riveting position due to rivet offset during feeding and mold damage or equipment shutdown caused by rivet and mold jamming are solved.

[0009] Furthermore, the feeding mechanism includes a feeding push plate and a floating card seat arranged on the feeding push plate, and the guide hole is vertically penetrated and arranged on the floating card seat; a feeding guide rail and a driving member are also arranged on the feeding station, and the driving member is connected to the feeding push plate, and the feeding push plate is slidably arranged on the feeding guide rail, and a vertically penetrating mounting groove is arranged on the feeding push plate, and the floating card seat is slidably arranged on the mounting groove.

[0010] Beneficial effects: The driving member drives the feeding push plate to slide on the feeding guide rail, thereby driving the floating card seat to move to the bottom of the pushing mechanism to realize feeding; by setting the floating card seat, on the one hand, it is used to fine-tune the position of the floating card seat so that the parts in the guide hole can accurately enter the mounting hole of the feeding mechanism; on the other hand, the floating card seat slides downward when subjected to the downward pressure of the pushing mechanism, and is used to cooperate with the feeding mechanism to realize accurate insertion of the parts into the mounting hole.

[0011] Furthermore, the longitudinal section of the floating card seat is a T-shaped structure, including a vertical section and a horizontal section, and a avoidance groove for the discharge pipe of the vibration plate to pass through is opened at the connection between the vertical section and the horizontal section, and the avoidance groove is connected to the guide hole; the vertical section of the floating card seat is slidably arranged in the mounting groove of the feeding push plate, and the horizontal section is located above the feeding push plate and is connected to the upper surface of the feeding push plate through a spring. When the spring is in a compressed state, the bottom of the vertical section extends out of the mounting groove.

[0012] Beneficial effect: Since the floating card seat will move on the feeding guide rail with the feeding push plate, by arranging an avoidance groove on the floating card seat, when the floating card seat is reset, it can ensure that the discharge pipe of the vibration plate passes through the avoidance groove and is aligned with the guide hole, ensuring that the rivet parts can smoothly enter the guide hole; the floating card seat and the feeding push plate are connected by a spring, when the pushing mechanism presses down the floating card seat so that the spring is in a compressed state, the floating card seat slides in the installation groove and extends out of the installation groove, which is used to cooperate with the feeding mechanism to allow the parts to smoothly enter the installation hole of the feeding mechanism.

[0013] Furthermore, the avoidance groove divides the horizontal section of the floating clamp into two sections, and a avoidance notch for avoiding the discharge pipe is provided on the section close to the vibration plate; limiting holes are provided on the horizontal section of the floating clamp and the feeding push plate, one end of the spring is located in the limiting hole of the horizontal section, and the other end is located in the limiting hole of the feeding push plate.

[0014] Beneficial effect: the setting of the avoidance gap can further avoid the interference between the floating clamp and the discharge pipe; by setting the spring in the limit hole to play a limit role, it is beneficial to improve the stability of the floating clamp when sliding up and down.

[0015] Furthermore, the pushing mechanism includes a pushing cylinder, a pressure block, and a pushing ejector. The pushing cylinder is arranged on a mounting seat, the pressure block is arranged on a piston rod of the pushing cylinder, and a mounting cavity is also arranged on the pressure block. The pushing ejector is slidably arranged on the mounting cavity through a spring, and the pushing ejector extends out of the mounting cavity to push the parts in the guide hole of the floating card seat into the feeding mechanism.

[0016] Beneficial effects: When in use, the push pin is used to push out the parts in the mounting hole of the floating card seat, and the pressure block is used to push the floating card seat downward, so that the vertical section of the floating card seat extends out of the mounting slot and cooperates with the feeding mechanism; the ejector is connected by a spring, and the floating of the ejector can be used to fine-tune the parts in the mounting hole, so that the parts are vertically pushed into the mounting hole of the feeding mechanism.

[0017] Furthermore, the loading mechanism is arranged on the loading station, and a loading guide rail and a driving member are arranged on the loading station; the loading mechanism includes a loading push plate and a conical clamping block vertically slidably arranged on the loading push plate, one end of the loading push plate is connected to the driving member and is slidably arranged on the loading guide rail, and the mounting hole is arranged on the conical clamping block.

[0018] Beneficial effect: The driving member is used to push the feeding push plate to slide on the feeding track, so that the parts on the conical clamping block are transported to the riveting station. The conical clamping block is slidably arranged on the feeding push plate, and the floating clamping seat is used to push the conical clamping block to move downward.

[0019] Furthermore, a mounting block is provided at the bottom of the feeding push plate, a guide groove is provided in the mounting block, a feeding ejector is slidably provided in the guide groove through a spring, the top of the feeding ejector passes through the feeding push plate and is connected to the bottom of the conical clamping block, and the feeding ejector is slidably connected to the feeding push plate.

[0020] Beneficial effect: The conical clamping block is reset by the feeding ejector pin and the spring. When the pressing block pushes the floating clamping seat to move downward, the floating clamping seat is used to push the conical clamping block downward. At this time, the part is pushed out of the guide hole, and the end of the part enters the mounting hole of the conical clamping block; when the pressing block moves upward, the floating clamping seat and the conical clamping block are reset under the action of the spring, and the compressed spring in the ejector pin is gradually released, and pushes the ejector pin to continue to push the part downward. When the conical clamping block is reset, the part is clamped into the mounting hole.

[0021] Furthermore, an arc-shaped guide edge is provided at the top of the mounting hole.

[0022] Beneficial effect: The arc-shaped guide edge guides the parts to ensure that the parts enter the installation holes smoothly.

[0023] Furthermore, a punch is also arranged in the feeding push plate, the upper part of the punch is located in the mounting hole of the conical block, and the top of the punch is flush with the top of the feeding push plate.

[0024] Beneficial effect: The punch can be provided to limit the parts in the mounting hole, so that the parts in the mounting hole can be smoothly riveted into the mold during stamping and riveting.

[0043] The use process of a stud assembly feeding device is as follows:

[0044] First, the parts are discharged from the vibration plate 100 along the discharge pipe 101 in sequence. Since the outlet of the discharge pipe 101 is aligned with the guide hole 131 on the floating holder 13, the parts fall into the guide hole 131; then the feeding push plate 12 is pushed by the feeding cylinder 110 to move on the feeding guide rail, and the floating holder 13 is pushed to the bottom of the pressing block 22; at this time, the pushing cylinder 21 is started, and the pushing cylinder 21 drives the pressing block 22 and the pushing ejector pin 23 to move downward, and the pushing ejector pin 23 is aligned with the guide hole 131. When the pushing ejector pin 23 and the pressing block 22 move downward, the pushing ejector pin 23 first contacts the part in the guide hole 131. Since the pushing ejector pin 23 is connected by the spring 300, when it contacts the part, it can be used to fine-tune the part so that it is in a vertical state in the guide hole 131;

[0045] When the pressing block 22 continues to move downward, it pushes the floating clamp 13 downward, so that the vertical section of the floating clamp 13 extends out of the feeding push plate 12, so that the floating clamp 13 is used to move the conical clamp 33 downward until the top of the conical clamp 33 is flush with the top of the feeding push plate 32 (such as Figure 7 As shown in the figure, at this time, the bottom of the part in the guide hole 131 is located at the opening of the mounting hole 331 of the conical block 33. When the push cylinder 21 drives the pressing block 22 to move upward, the spring 300 in the mounting block 34 is reset, and the conical block 33 is pushed out and reset by the feeding ejector 35. At the same time, the ejector 23 continues to press against the part under the action of the spring 300, so that the part enters the mounting hole 331 of the conical block 33 (as shown in the figure). Figure 6 shown);

[0046] Finally, the feeding cylinder is used to push the feeding push plate 32 to slide on the feeding guide rail, so that the conical block 33 is located on the assembly station. When stamping, the template moves downward and presses the conical block 33 down again until it is flush with the feeding push plate 32, and the parts are riveted on the template, thereby realizing stamping and riveting.
