Description
Technical Field
[0001] The utility model belongs to the technical field of mechanical automated processing, and relates to a riveting auxiliary feeding mechanism, in particular to a rivet auxiliary feeding mechanism for riveting. Background Art
[0002] Riveting is a commonly used processing method in the field of machining, and rivets are essential parts in riveting. In the traditional riveting process, operators need to manually pick up rivets and place them in the correct position for processing or assembly. However, with the continuous development of industrial automation technology, the traditional manual picking method can no longer meet the modern manufacturing industry's demand for high efficiency and high precision.
[0003] At present, rivet feeding by robots has been widely used in automated production lines. However, during the rivet feeding process, the recognition and picking up of rivets by robots basically rely on complex visual systems and precise robotic arm motion control. Although this method can achieve automation, it has problems such as high recognition accuracy requirements, complex system structure, slow feeding speed, and high cost. In addition, due to the small size and large number of rivets, robots are prone to misidentification and misoperation when picking them up, affecting production efficiency and product quality. Utility Model Content
[0004] In view of the above-mentioned deficiencies existing in rivet feeding, the utility model proposes an auxiliary feeding mechanism for riveting, which can reduce the rivet feeding time, improve the centering accuracy between the rivet gun and the rivet, provide convenience for subsequent processing or assembly, and further improve the stability and consistency of product quality.
[0005] The auxiliary feeding mechanism for riveting provided in this application adopts the following technical solution:
[0006] The auxiliary feeding mechanism for riveting comprises a frame, a rivet gun assembly connected to one side of the frame, and a mounting base plate connected to the other side of the frame, wherein the auxiliary feeding mechanism further comprises:
[0007] A pneumatic push rod, connected and fixed to the mounting base plate;
[0008] A movable seat is connected and fixed to the output end of the pneumatic push rod and moves up and down along with the pneumatic push rod;
[0009] Open and close guide rails, connected and fixed to the frame;
[0010] The opening and closing bracket is hingedly connected to the movable seat at the bottom and clamped to the opening and closing guide rail at the top, and opens and closes along the opening and closing guide rail while the movable seat moves up and down;
[0011] The rivet bin is connected and fixed to the opening and closing bracket, and performs lifting and opening and closing movements along with the opening and closing bracket.
[0012] By adopting the above technical solution, the pneumatic push rod drives the movable seat to move up and down, the movable seat drives the opening and closing bracket to move up and down, and then the opening and closing bracket drives the rivet bin to move up and down; at the same time, the opening and closing bracket acts along the opening and closing guide rail when moving up and down, prompting the opening and closing bracket to rotate around the movable seat to form an opening and closing, thereby driving the opening and closing of the rivet bin. When the rivet bin moves downward, the rivet blanking action is completed, and when the rivet bin is opened, the rivet gun assembly completes the riveting action.
[0013] Furthermore, the pneumatic push rod is clamped and fixed by an inner clamp, and the inner clamp is connected and fixed to the mounting base plate through an outer bracket.
[0014] By adopting the above technical solution, the pneumatic push rod is stably fixed relative to the mounting base plate through the inner chuck and the outer bracket, and the inner chuck also facilitates fine adjustment of the working stroke of the pneumatic push rod.
[0015] Furthermore, the movable seat is connected and fixed to the output end of the pneumatic push rod via a connector, and the connector is spirally connected to the output end of the pneumatic push rod.
[0016] By adopting the above technical solution, the pneumatic push rod and the movable seat can be quickly installed and disassembled, which is beneficial to later maintenance and replacement.
[0017] Furthermore, a linear slider assembly is connected between the movable seat and the mounting base plate. The linear slider assembly is composed of a linear guide rail, a linear slider and a connecting plate. The linear guide rail is connected and fixed to the mounting base plate, the linear slider is slidably connected to the linear guide rail, one end of the connecting plate is connected and fixed to the linear slider, and the other end is connected and fixed to the movable seat.
[0018] By adopting the above technical solution, the linear slider assembly can assist in guiding the push of the pneumatic push rod, so that the movable seat is more evenly stressed and moves up and down more smoothly.
[0019] Furthermore, the opening and closing guide rail is connected and fixed to the bottom of the frame, and the width of the opening and closing guide rail decreases from top to bottom.
[0020] By adopting the above technical solution, the change in the width of the opening and closing guide rail can make the opening and closing degree of the opening and closing bracket match it, thereby realizing the opening and closing of the rivet bin.
[0021] Furthermore, the opening and closing bracket is composed of a left opening and closing bracket and a right opening and closing bracket, both of which are rotatably connected to the movable seat through a pin shaft.
[0022] By adopting the above technical solution, a pin is added at the connection between the opening and closing bracket and the movable seat, so that the rotation of the opening and closing bracket relative to the movable seat is smoother, ultimately ensuring the smooth opening and closing of the rivet bin.
[0023] Furthermore, the top of the opening and closing bracket is connected with a roller.
[0024] By adopting the above technical solution, a roller is arranged on the top of the opening and closing bracket, which is beneficial to the sliding contact between the opening and closing bracket and the opening and closing guide rail, reduces sliding friction, and is beneficial to the smooth opening and closing of the opening and closing bracket.
[0025] Furthermore, the rivet bin is composed of a left rivet bin and a right rivet bin, and a blanking tube is connected to the top of one of the rivet bins. When the two rivet bins are combined, the middle part presents a cylindrical hollow structure, and the blanking tube is connected to the cylindrical hollow structure, and the bottom of the cylindrical hollow structure is a countersunk hole.
[0026] By adopting the above technical solution, the rivet is limited at the countersunk hole in the rivet bin where it falls from the blanking tube, making it easy for the rivet gun to align with the rivet for use.
[0027] In summary, the present invention includes at least one of the following beneficial technical effects:

[0029] (2) The utility model can automatically, accurately and efficiently deliver rivets to the working area of the robot, eliminating the step of the complex visual robot taking the rivets, thereby reducing the difficulty of operation and equipment cost.
[0030] (3) After the rivet is dropped, the centering accuracy between the rivet gun and the rivet is high, which can ensure the stability and consistency of the quality of the riveted product, further meeting the needs of modern manufacturing industry for high efficiency and high precision.

DETAILED DESCRIPTION
[0041] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. After reading the present invention, modifications to various equivalent forms of the present invention by those skilled in the art fall within the scope defined by the claims attached to this application.
[0042] Example 1
[0043] like Figure 1-3 As shown, the auxiliary feeding mechanism for riveting is composed of a frame 1, a rivet gun assembly 2 connected to one side of the frame 1, a mounting base plate 3 connected to the other side of the frame 1, a pneumatic push rod 6 fixedly connected to the mounting base plate 3, a movable seat 7 fixedly connected to the output end of the pneumatic push rod 6 and lifting and lowering with the pneumatic push rod 6, an opening and closing guide rail 13 fixedly connected to the frame 1, an opening and closing bracket 8 hingedly connected to the movable seat 7 at the bottom and clamped to the opening and closing guide rail 13 at the top, and a rivet bin 9 fixedly connected to the opening and closing bracket 8. The opening and closing bracket moves up and down with the movable seat 7 and opens and closes along the opening and closing guide rail 13; the rivet bin 9 moves up and down and opens and closes with the opening and closing bracket 8.
[0044] The pneumatic push rod 6 drives the movable seat 7 to move up and down, the movable seat 7 drives the opening and closing bracket 8 to move up and down, and then the opening and closing bracket 8 drives the rivet bin 9 to move up and down; at the same time, the opening and closing bracket 8 acts along the opening and closing guide rail 13 when moving up and down, prompting the opening and closing bracket 8 to rotate around the movable seat 7 to form an opening and closing, thereby driving the opening and closing of the rivet bin 9. When the rivet bin 9 moves downward, the rivet blanking action is completed. When the rivet bin 9 is opened, the riveting action is completed by the rivet gun assembly 2.
[0045] Example 2
[0046] In order to stabilize the pneumatic push rod relative to the mounting base plate and facilitate fine adjustment of the working stroke of the pneumatic push rod, the inner chuck and the outer bracket are fixed together in this embodiment. Specifically, Figure 3 As shown, the pneumatic push rod 6 is clamped and fixed by the inner clamp 4, and the inner clamp 4 is connected and fixed to the mounting base plate 3 through the outer bracket 5.
[0047] In order to make the pneumatic push rod and the movable seat form a quick installation and detachable, it is convenient for later maintenance and replacement. In this embodiment, a connector structure is used between the pneumatic push rod and the movable seat. Specifically, Figure 5-6 As shown, the movable seat 7 is connected and fixed to the output end of the pneumatic push rod 6 via a connector 15 , and the connector 15 is screw-connected to the output end of the pneumatic push rod 6 .
[0048] In order to assist the pneumatic push rod in pushing and guide the movable seat to be more evenly stressed and move up and down more smoothly, a linear slider assembly is provided between the movable seat and the mounting base in this embodiment. Figure 2 As shown, a linear slider assembly is connected between the movable seat 7 and the mounting base plate 3. The linear slider assembly consists of a linear guide rail 10, a linear slider 11 and a connecting plate 12. The linear guide rail 10 is connected and fixed to the mounting base plate 3, the linear slider 11 is slidably connected to the linear guide rail 10, one end of the connecting plate 12 is connected and fixed to the linear slider 11, and the other end is connected and fixed to the movable seat 7.
[0049] Example 3
[0050] In order to match the opening and closing degree of the opening and closing bracket with the profile of the opening and closing guide rail, the rivet bin can be opened and closed. In this embodiment, the profile of the opening and closing guide rail is set, specifically, Figure 4 , Figure 7 As shown, the opening and closing guide rail 13 is connected and fixed at the bottom of the frame 1, and the width of the opening and closing guide rail 13 decreases from top to bottom. When the opening and closing bracket 8 moves to the upper end (wider part) of the opening and closing guide rail 13, the opening and closing bracket 8 is opened; when the opening and closing bracket 8 moves to the lower end (narrower part) of the opening and closing guide rail 13, the opening and closing bracket is closed.
[0051] In order to make the rotation of the opening and closing bracket relative to the movable seat smoother and ultimately ensure the smooth opening and closing of the rivet bin 9, in this embodiment, a pin shaft 16 is added at the connection between the opening and closing bracket 8 and the movable seat 7. Specifically, Figure 5-6 As shown, the opening and closing bracket 8 is composed of a left opening and closing bracket 8 - 1 and a right opening and closing bracket 8 - 2 , both of which are rotatably connected to the movable seat 7 via a pin shaft 16 .
[0052] In order to facilitate the contact between the opening and closing bracket 8 and the opening and closing guide rail 13, and facilitate the smooth opening and closing of the opening and closing bracket 8, the roller 14 is used in this embodiment. Specifically, Figure 5-6 As shown, the top of the opening and closing bracket 8 is connected with a roller 14, and the roller 14 forms a rolling contact with the opening and closing guide rail 10, thereby reducing friction.
[0053] In order to facilitate the positioning of the rivets in the rivet bin and facilitate the rivet gun to align the rivets for use, the structure inside the rivet bin is set in this embodiment, specifically, Figure 8-9 As shown, the rivet bin 9 consists of a left rivet bin 9-1 and a right rivet bin 9-2, wherein a blanking tube 9-3 is connected to the top of one of the rivet bins 9, and the middle part of the two rivet bins is a cylindrical hollow structure after the two rivet bins are combined, and the blanking tube 9-3 is connected to the cylindrical hollow structure, and the bottom of the cylindrical hollow structure is a countersunk hole 9-4, and the rivet is limited by the countersunk hole 9-4.
[0054] like Figure 1-9 As shown, the working principle of the auxiliary feeding mechanism for riveting is as follows: Rivet dropping: the pneumatic push rod 6 moves downward to drive the movable seat 7, linear slider 11, connecting plate 12, opening and closing bracket 8, and rivet bin 9 to move downward synchronously. At this time, a space is formed between the rivet gun and the countersunk hole 9-4 at the bottom of the rivet bin, and the rivet falls into the countersunk hole 9-4 of the rivet bin through the dropping tube 9-3. At this time, the electric rivet gun head rotates synchronously to take the rivet.
[0055] Riveting with a rivet gun: The pneumatic push rod 6 moves upward to drive the movable seat 7, the linear slider 11, the connecting plate 12, the opening and closing bracket 8, and the rivet bin 9 to move upward synchronously. The opening and closing bracket 8 moves along the opening and closing guide rail 13. Since the upper part of the opening and closing guide rail 13 gradually widens, the opening and closing bracket 8 opens to the maximum state during the upward movement, so that the rivet bin 9 does not interfere with the work of the rivet gun. At this time, the rivet gun can drive rivets at the required position to complete a blanking and riveting cycle.
