[0025] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0026] like Figure 1 — Figure 7 As shown, the riveting fixture for a current collector 400 of this utility model includes a support component 100, a current collector 400, a push component 200, a rod 210, and a pressing component 300.

[0027] In this utility model, the current collection assembly 400 includes a current collection pipe 410, a bracket 420 and a pipe body 430. Before riveting with a riveting tool, the bracket 420 and the current collection pipe 410 are connected by bolts 440, and one end of the pipe body 430 is inserted into the current collection pipe 410.

[0028] The support assembly 100 is used to position and place the current collection assembly 400. A pushing assembly 200 is provided on one side of the support assembly 100. The pushing assembly 200 holds a rod 210 and can push the rod 210 into the current collection assembly 400. The pressing assembly 300 is located directly above the support assembly 100. The rod 210 has rivet holes 211 corresponding to bolts 440. The rod 210 also has rivet grooves 212 for inserting pipe bodies 430. An expansion platform 213 is provided in the rivet groove 212. Multiple cutting plates 21 are arranged around the edge of the expansion platform 213. 4. When riveting the current collector assembly 400, it needs to be positioned on the support assembly 100. Then, the push assembly 200 sends the rod 210 into the current collector tube 410, with the bolt 440 positioned directly above the rivet hole 211 and the tube 430 inserted into the current collector tube 410 positioned directly above the rivet groove 212. Afterward, the pressing assembly 300 is controlled to move downward. When the pressing assembly 300 presses against the support assembly 100, it simultaneously presses against the bolt 440, bracket 420, tube 430, and current collector tube 410. The bottom end of bolt 440 is inserted into the rivet groove 212, creating a compressive force between bolt 440 and the inner wall of rivet hole 211. This causes bolt 440 to undergo physical deformation. Specifically, bolt 440 inserted into manifold 410 expands laterally, thus securing the bottom end of bolt 440 within manifold 410, thereby achieving the press-fit connection between bracket 420 and manifold 410. Simultaneously, one end of pipe body 430 inserted into manifold 410 enters the rivet groove 212, and expansion plate 213 is inserted into pipe body 430, allowing cutting plate 214 to cut open the side wall of pipe body 430. Because the width of the partition gradually increases from top to bottom, the cut tube 430 will fold outward, thus forming a trumpet shape. Then, the cut tube 430 will be squeezed by the rivet groove 212, causing it to fold towards the connection between the manifold 410 and the tube 430. In this way, the tube 430 can be stuck on the manifold 410, that is, the tube 430 and the manifold 410 are riveted together. After the riveting is completed, the pressing component 300 is raised and reset, and the pushing component 200 pushes the rod 210 out of the manifold 410.

[0029] like Figure 4 — Figure 7As shown, the support component 100 includes a base plate 110 and a movable plate 120 elastically connected to the base plate 110. The movable plate 120 is provided with a positioning element 130. The current collecting component 400 is placed on the movable plate 120, and one side of the current collecting component 400 is in contact with the positioning element 130. Through the function of the positioning element, the current collecting component 400 can be positioned on the movable plate 120. Furthermore, when the pressing component presses down on the current collecting component, the pressing component will also press down on the end of the positioning element close to the current collecting component at the same time, so as to avoid the current collecting component from being misaligned during the pressing process.

[0030] Furthermore, a fixing plate 111 is provided on the base plate 110, and multiple support plates 112 for supporting the rod body 210 are provided on the fixing plate 111. Each support plate 112 movably passes through the movable plate 120. Multiple springs 113 are provided between the fixing plate 111 and the support plates 112. A through hole (not shown in the figure) corresponding to the support plate 112 is provided on the bottom surface of the manifold 410. When the manifold 410 is placed on the movable plate 120, the top of each support plate 112 needs to be inserted into the corresponding through hole. The movable plate 120 is not pressed by the pressing assembly 300, but only by the elastic force of the spring 113, so that the movable plate 120 can raise the height of the manifold 410 and prevent the support plate 112 from extending into the manifold 410. This ensures that when the rod 210 is inserted into the manifold 410, the rod 210 will not contact the bolt 440 and the pipe body 430. However, the top of each support plate 112 will contact the bottom surface of the rod 210, or there will be a small gap between the top of the support plate 112 and the support plate 112. When the pressing assembly 300 presses... When the current collector assembly 400, movable plate 120, and positioning component 130 are in operation, the movable plate 120, positioning component 130, and current collector assembly 400 are simultaneously moved towards the fixed plate 111 under force. The spring 113 is compressed under force, and the support plate 112 is fixed to the fixed plate 111. The top end of the support plate 112 will extend into the current collector pipe 410 relative to the current collector pipe 410. In this way, the current collector pipe 410, bracket 420, and pipe body 430 will move downward, and the support plate 112 will support the rod body 210, thereby enabling the rod body 210 to engage with the bolt 44. Force is applied to the end of the tube 430 to complete the riveting work. After the riveting is completed, the pressing component 300 is raised and no longer applies force to the movable plate 120. At this time, the movable plate 120 is acted upon by the spring 113 and will move away from the fixed plate 111. At the same time, the movable plate 120 will raise the current collecting component 400. In this way, the rod 210 will no longer contact the bolt 440 and the tube 430. Therefore, the pushing component 200 can smoothly move the rod 210 out of the current collecting tube 410.

[0031] The positioning component 130 includes a movable plate 131 slidably connected to the movable plate 120 and a third cylinder 133 disposed on the movable plate 120. The third cylinder 133 is used to push the movable plate 131 to move. A positioning block 132 and a limiting block 134 are provided on one side of the movable plate 131. Specifically, the positioning block 132 has an arc-shaped surface 132a on the side away from the movable plate 131. The limiting block 134 has a limiting groove 134a. A limiting plate 140 is provided on the movable plate. The end of the movable plate near the positioning block can move through the limiting plate. The top of the limiting plate has a locking groove 131a. The manifold 410 is placed in the groove (not shown in the figure) of the movable plate 120, and the bracket 420 is tightened with bolts 440. After inserting one end of the pipe body 430 into the manifold 410, the third cylinder 133 needs to be operated to move the moving plate 131 toward the manifold 410. When the moving plate 131 moves to the predetermined displacement, the side of the positioning block 132 near the bracket 420 is attached to the bracket 420, and the arc surface 132a is also attached to the side of the bottom of the bracket 420. At the same time, the corner of the pipe body 430 is inserted into the limiting groove 134a of the limiting block 134. In this way, the manifold can be positioned and placed on the support assembly 100. During this process, the end of the pipe body 430 away from the manifold 410 is always slidably locked in the locking groove 131a of the moving plate 131, thereby achieving stable support of the pipe body 430 by the moving plate 131.

[0032] A support plate 114 is provided below the base plate 110. The pushing component 200 includes a clamping block 220 slidably connected to the support plate 114 and a second cylinder 230 disposed on the support plate 114. The second cylinder 230 is used to push the clamping block 220 to move. The clamping block 220 is used to clamp the rod 210. When the second cylinder 230 is working, the second cylinder 230 will slide relative to the support plate 114 with the clamping block 220, so that the rod 210 moves relative to the support plate 114, thereby realizing the insertion of the rod 210 into the manifold 410 or the removal of the rod from the manifold 410.

[0033] like Figure 1 — Figure 5 As shown, the pressing assembly 300 includes a pressing block 310 movably disposed directly above the movable plate 120 and a first cylinder 320 for driving the pressing block 310 to rise and fall. During operation, when the positioning block 132 moves with the movable plate 131 to directly below the pressing block 310, the bracket 420 abuts against one side of the positioning block 132, and the corner of the tube 430 is inserted into the limiting groove 134a. After that, the first cylinder 320 lowers the pressing block 310, which can simultaneously press down the positioning block 132, the limiting block 134, the tube 430, the manifold 410, and the bolt 440.

[0034] Furthermore, the pressure block 310 is provided with a pressing block 311. The bottom surface of the pressure block 310 is provided with a pressing groove 312 for installing the pressing block 311. The bottom surface of the pressing block 311 is provided with an arc-shaped pressing surface 311a. The bottom surface of the pressure block 310 is also provided with a limiting foot 313 corresponding to the limiting block 134. When the bottom end of the pressure block 310 contacts the movable plate 120, the top end of the positioning block 132 is inserted into the pressing groove 312. The bottom surface of the pressing block 311 is attached to one side of the bracket 420. The pressing surface 311a is attached to the side of the manifold 410. The limiting foot 313 presses down on the limiting block 134. In this way, the pressure block 310 can simultaneously press down on the positioning block 132, the limiting block 134, the pipe body 430, the manifold 410, and the bolt 440.

[0035] A lifting plate 330 is provided on the top surface of the pressure block 310, a top plate 340 is provided above the bottom plate 110, and a base 360 ​​is provided below the support plate. The lifting plate 330 is movably located between the top plate 340 and the movable plate. Multiple guide rods 350 are provided between the top plate 340 and the base 360. The guide rods 350 pass through the lifting plate 330. The first cylinder 320 is located on the top plate 340. During operation, the first cylinder 320 carries the lifting plate 330 and moves it up and down along the trajectory of the guide rods 350. Since the pressure block 310 is located at the bottom surface of the lifting plate 330, the directional lifting and lowering of the pressure block 310 can be achieved.

[0036] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0037] Furthermore, in this utility model, the use of terms such as "first," "second," and "a" is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0038] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0039] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
