Description

Technical Field

[0001] This utility model relates to the technical field of rivet feeding devices, and in particular to a rivet feeding mechanism for busbar trunking production. Background Art

[0002] Busbar trunking is a closed metal device made of copper or aluminum busbars, used to distribute large amounts of power to various components in a distributed system. Currently, it is gradually replacing electrical wires and cables in indoor low-voltage power transmission trunk line projects.

[0003] Currently, when processing busbar trunking, the busbar trunking first needs to be assembled. This requires using clamps to hold the busbar trunking on the assembly line, and then installing the cover plates of the busbar trunking. After assembly, the cover plates on both sides need to be riveted and fixed to complete the assembly of the busbar trunking, as disclosed in Chinese Patent Publication No. "CN118399292B" for a dense busbar trunking assembly line.

[0004] In rivet assembly, the common feeding method is to fix the rivets to a strip and supply them via a reel for winding and unwinding. Although a servo motor-driven reel ensures feeding accuracy, its high purchase and maintenance costs limit large-scale application by small and medium-sized enterprises. Therefore, to further improve the applicability of rivet feeding, we propose a rivet feeding mechanism for busbar trunking production. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the high purchase and maintenance costs of motor-driven reels which limit large-scale application by small and medium-sized enterprises, while ensuring accurate material feeding. Therefore, this invention proposes a rivet feeding mechanism for busbar production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a rivet feeding mechanism for busbar production, including two horizontal bars supported by a bracket, a vertical bar slidably connected between the two horizontal bars, and a slide block slidably connected to the inner side of the vertical bar, the sliding direction of the slide block being perpendicular to the sliding direction of the vertical bar;

[0008] The slide block has an inclined plate installed at its bottom. The lower end of the inclined plate is detachably connected to a bracket. A support column for inserting a rivet disc is also installed on the end face of the bracket. The extension direction of the support column forms a predetermined angle with the longitudinal rod.

[0009] Furthermore, the longitudinal bar has a T-shaped slide rail extending to its outer side, and the inclined plate slides at the opening of the T-shaped slide rail;

[0010] Two support plates are fixedly installed on the upper and lower sides of the slide, and guide wheels are installed on the support plates.

[0011] Furthermore, the axle of the guide wheel passes through the support plate, and a positioning glass bead is also embedded on the outside of the axle to stop the other side of the support plate.

[0012] Furthermore, the rack includes a first frame and a second frame vertically connected to the lower side of the first frame, wherein the first frame is fixed to the inclined plate by fasteners, and the support column is connected to the second frame.

[0013] Furthermore, both the first frame and the second frame are made of angle iron, and an angle adjustment structure is also provided between the first frame and the second frame.

[0014] Furthermore, the angle adjustment structure includes a fixed frame fixed on the second frame, the fixed frame being in contact with the inner side of the first frame, and guide grooves being provided on the end faces of the fixed frame and the first frame, with a locking member passing through the two guide grooves.

[0015] Furthermore, one end of the support column has a threaded rod that passes through the bracket, and the threaded rod is locked by a nut.

[0016] The present invention proposes a rivet feeding mechanism for busbar production, which has the following advantages: In this invention, the longitudinal rod mounted above the workbench allows for multi-position movement of the hanging frame during rivet feeding operations on the busbar, meeting the operational needs of different positions. Furthermore, in this embodiment, because the hanging frame drives the support column to be tilted, the rivet disc is in an inclined state when supported. This ensures that the rivet disc can be freely pulled for feeding while preventing it from unwinding freely. Compared to servo motor-driven unwinding feeding, this mechanism is simple in design and low in cost, possessing high practicality and promotional value. Attached Figure Description

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-3 In one embodiment of this utility model, a rivet feeding mechanism for busbar trunking production is disclosed. This feeding mechanism supports the reel of self-piercing rivet strips to ensure free rotation and unwinding the rivet strip. Specifically, the mechanism includes two horizontal bars 1 supported by a bracket. In this embodiment, the two horizontal bars 1 are mounted above the workbench and are horizontally arranged. A vertical bar 2 is slidably connected between the two horizontal bars 1, and a slide block 3 is slidably connected to the inner side of the vertical bar 2. In a preferred embodiment, the sliding method between the vertical bar 2 and the horizontal bar 1 can refer to the sliding method between the vertical bar 2 and the slide block 3 described below, which will not be elaborated here. The sliding direction of the slide block 3 is perpendicular to the sliding direction of the vertical bar 2.

[0023] In this embodiment, a sloping plate 4 is installed at the bottom of the slide block 3. A hanger 5 is detachably connected to the lower end of the sloping plate 4. A support column 6 for threading the rivet disc is also installed on the end face of the hanger 5. The extension direction of the support column 6 forms a predetermined angle with the longitudinal rod 2. Preferably, in this embodiment, the inclined support column 6 is used to provide inclined support for the rivet disc, which ensures that the rivet disc can be freely pulled for feeding while preventing it from unwinding freely. In addition, refer to Figure 2 As shown in the figure, α represents a predetermined angle. Specifically, in this embodiment, the predetermined included angle is set to 40°-70°.

[0024] In some embodiments, the longitudinal rod 2 of this invention has a T-shaped slide rail extending to its outer side, the inclined plate 4 slides at the opening of the T-shaped slide rail, and the slide block 3 slides on the upper part of the T-shaped slide rail.

[0025] Two support plates 31 are fixedly installed on the upper and lower sides of the slide block 3. Guide wheels 32 are installed on the support plates 31. That is, in this embodiment, four guide wheels 32 are used to support and guide the sliding of the slide block 3, so as to improve the sliding stability of the slide block 3.

[0026] Based on the above embodiments, in this embodiment, the shaft of the guide wheel 32 passes through the support plate 31, and a positioning glass bead 33 is also embedded on the outside of the shaft to stop on the other side of the support plate 31. That is, the guide wheel 32 in this embodiment is detachably connected. When it is necessary to disassemble the guide wheel 32, simply press the positioning glass bead 33 to pull the guide wheel 32 out of the support plate 31, thus improving the convenience of assembly and maintenance.

[0027] Furthermore, in this embodiment, the hanging bracket 5 includes a first bracket 51 and a second bracket 52 vertically connected to the lower side of the first bracket 51. The first bracket 51 is fixed to the inclined plate 4 by fasteners 53, which are bolt and nut assemblies, thus achieving convenient assembly and disassembly. The support column 6 is connected to the second bracket 52.

[0028] In addition, in this embodiment, both the first frame 51 and the second frame 52 are set as angle irons, and an angle adjustment structure is also provided between the first frame 51 and the second frame 52. The height of the second frame 52 is adjusted by the angle adjustment structure, so that the height of the rivet disc can be adjusted to achieve the optimal operating height.

[0029] Based on the above embodiments, the angle adjustment structure in this embodiment includes a fixed frame 56 fixed on the second frame 52. The fixed frame 56 is in contact with the inner side of the first frame 51. Guide grooves 54 are also provided on the end faces of the fixed frame 56 and the first frame 51. A locking member 55 is provided between the two guide grooves 54. Preferably, the locking member 55 in this embodiment is a bolt and nut assembly. Of course, two guide grooves 54 are provided on both the fixed frame 56 and the first frame 51. Through the design of the guide grooves 54, the height of the second frame 52 can be adjusted. After adjustment, it can be locked by the bolt and nut assembly. The operation is simple and convenient. In a further embodiment, the fixed frame 56 in this utility model is also set as an angle iron, so as to ensure the stability of the lifting and lowering adjustment of the second frame 52.

[0030] It should be noted that, in this embodiment, one end of the support column 6 has a threaded rod 61 that passes through the bracket 5. The threaded rod 61 is locked by a nut. By using the nut locking method, the support column 6 can be conveniently installed.

[0031] In summary, this utility model utilizes the vertical rod 2 mounted above the workbench to enable the hanging bracket 5 to move in multiple positions during the riveting operation of the busbar trough, thus meeting the operational needs of different positions. Furthermore, in this embodiment, because the hanging bracket 5 drives the support column 6 to be tilted, the rivet disc is in an inclined state when supported. This ensures that the rivet disc can be freely pulled for feeding while preventing it from unwinding freely. Compared to the servo motor-driven unwinding and feeding method, this mechanism is simple in design and low in cost, possessing high practicality and promotional value.
