Description

Technical Field

[0001] This invention relates to the field of brake equipment processing technology, and in particular to a brake buffer seat assembly device. Background Technology

[0002] As a crucial component of the vehicle braking system, the brake buffer seat's primary function is to absorb and disperse the impact energy generated during emergency braking, reducing damage to the vehicle's structure. The main body of the brake buffer seat consists of a base plate and four side plates forming a buffer frame. The base plate and side plates are typically connected using internally threaded cylindrical pins and hexagonal head screws. Multiple nylon plates are stacked overlapping within the buffer frame. During assembly, the internally threaded cylindrical pins are first hammered into the side plates to secure them, followed by a secondary connection using hexagonal head screws to ensure a stable connection between the side plates. Finally, hexagonal head screws are used to connect the side plates and the base plate, assembling them into a buffer frame. To ensure the brake buffer seat can withstand braking impacts, both the side plates and the base plate are made of steel, resulting in significant weight. Furthermore, the current practice of manual assembly, requiring the side plates and base plate to be flipped during assembly, leads to extremely high labor intensity for workers and hinders production efficiency. Summary of the Invention

[0003] In view of the shortcomings of the above-mentioned prior art, this application provides a brake buffer seat assembly device that can automatically assemble the base plate and side plate, which not only reduces the labor intensity of workers, but also improves production efficiency and has strong practicality.

[0011] Furthermore, a baffle is provided on one of the flip plates away from the limiting strip to abut against the bottom plate.

[0012] Furthermore, the worktable is also provided with two long slots respectively located on the outside of the elongated hole and extending through one end away from the limiting strip.

The second transmission shaft is rotatably mounted below the worktable and connected to the output end of the second power device. The second power device is mounted below the worktable.

[0013] Furthermore, the end of the worktable away from the limit strip is provided with a groove. When in use, the base plate is located in the groove, and the side of the base plate abuts against the side of the groove. The surface of the rotating plate is provided with a protrusion. When the rotating plate is in a horizontal state, the rotating plate is flush with the bottom surface of the groove, and the protrusion is flush with the surface of the worktable.

[0014] Furthermore, the vertical material tubes are all installed on the connecting plate, and the side of the connecting plate is provided with a horizontal bar. One end of the horizontal bar is connected to the lifting frame. The top rods are all installed on the moving plate. The moving plate is sleeved on the horizontal bar and connected to the moving end of the second horizontal linear mechanism. The second horizontal linear mechanism is installed on the lifting frame.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the implementation methods of the present invention will be described in detail below with reference to the accompanying drawings. However, the embodiments described in this invention are only some embodiments of the present invention, and not all embodiments.

[0031] like Figures 1-10 As shown in the figure, this application provides a brake buffer seat assembly device, including: a worktable 100, a flipping mechanism 200, and an assembly mechanism 300.

[0032] A support plate 101 is provided above the workbench 100 and is movable along its width direction. The length direction of the support plate 101 is parallel to the width direction of the workbench 100. Both the top surfaces of the workbench 100 and the support plate 101 have two elongated holes 102 whose length direction is parallel to the width direction of the workbench 100. Conveyor belts that move vertically are provided inside the elongated holes 102 and on all four sides of the workbench 100 along its length direction. The conveyor belt located on one side of the workbench 100 along its length direction is used to transport the base plate, and the transport direction of this conveyor belt is parallel to the width direction of the workbench 100. Along the length of the workbench 100, the remaining conveyor belts are used to transport side panels. During assembly, two horizontal side panels are located on the support plate 101 and the workbench 100, respectively, while the other two vertical side panels are located on either side of the two horizontal side panels. One end of the support plate 101 and one side of the workbench 100 are each provided with a vertically movable limiting strip 103 for limiting the ends of the side panels. The flipping mechanism 200 includes three support frames 201 located at both ends of the workbench 100 and on the side away from the limiting strip 103. The support frames 201 extend along the length of the workbench 100. Two L-shaped flip plates 202 are movable and rotatable along the width of the assembly mechanism 300. These plates flip the side plates and bottom plate to a vertical position for assembly. The assembly mechanism 300 includes a lifting frame 301 located above the workbench 100 and movable vertically. Multiple vertically arranged vertical tubes 302 are provided on both sides of the lifting frame 301 for holding internally threaded cylindrical pins. The bottom ends of each vertical tube 302 are penetrated and fitted with push rods 303 that move along its width to push the internally threaded cylindrical pins. Pins connect the horizontal and vertical side plates together. The lifting frame 301 has multiple horizontally arranged transverse tubes 304 at the end away from the limit bar 103 for placing hexagonal head screws. One end of the transverse tube 304 is provided with a top tube 305 that moves along its width direction for pushing the hexagonal head screws. A rotating rod 306 is rotatably installed in the top tube 305 for tightening the hexagonal head screws and connecting the side plates and the bottom plate together. After assembly, the buffer frame is rotated 90 degrees to make the bottom plate horizontal and transferred to the conveyor belt for conveying away.

[0033] Specifically, such as Figures 1-5As shown, the side of the limiting bar 103 furthest from the center of the worktable 100 is arc-shaped, and a top plate 104 is provided at its lower end. A through rod 105 is provided on the bottom surface of the top plate 104, and the through rod 105 passes through the bracket 106. The bracket 106 is respectively installed on the bottom surface of the worktable 100 or the support plate 101. A first spring 107 is sleeved on the through rod 105. The two ends of the first spring 107 abut against the top plate 104 and the bracket 106 respectively, and are always in a compressed state. During the process of conveying the horizontal side plate to the support plate 101 and the worktable 100, the end face of the side plate will contact the arc-shaped surface of the limiting bar 103, and force the limiting bar 103 to move downward. The first spring 107 is further compressed until the side plate completely passes through the limiting bar 103. 03. At this time, the limiting bar 103 will pop out under the action of the first spring 107, thereby limiting the end of the side plate. At this time, the side plate on the worktable 100 is already in the assembly position, while the side plate on the support plate 101 is not yet in the assembly position. Then, the support plate 101 is moved toward the center of the worktable 100 to align the upper and lower side plates. The side of the limiting bar 103 located below simultaneously contacts the end of one horizontal and two vertical side plates to ensure the limiting effect on the side plates. The movement of the support plate 101 can adopt a gear and rack structure, that is, a rack is set below the support plate 101 along its length direction. The rack is driven by the gear to move, thereby realizing the movement of the support plate 101.

[0034] More specifically, such as Figures 3-4 As shown, limit blocks 111 are provided at both ends of the workbench 100 along its length. The side of the limit block 111 away from the center of the workbench 100 is arc-shaped, and a stop plate 112 is provided at the lower end. A protruding rod 113 is provided on the bottom surface of the stop plate 112. The protruding rod 113 is inserted into the base frame 114, which is installed at the bottom of the workbench 100. A second spring 115 is sleeved on the protruding rod 113. The second spring 115 abuts against the base frame 114 and the stop plate 112 respectively, and is always in a compressed state. After the side plate is rotated 90 degrees to make it vertical, it is moved toward the center of the workbench 100. The side plate will contact the arc-shaped surface of the limit block 111 and force the limit block 111 to move downward. The second spring 115 is further compressed until the vertical side plate abuts against the horizontal side plate. At this time, the limit block 111 will pop out under the action of the second spring 115, thereby limiting the vertical side plate.

[0035] Specifically, such as Figure 2 , Figure 6As shown, both ends of the support frame 201 are sleeved on the support rod 207 and connected to the moving end of the first horizontal linear mechanism. The support rod 207 and the first horizontal linear mechanism are both installed at the bottom of the worktable 100. After the conveyor belt transports the side plate to both ends of the worktable 100 along its length, the conveyor belt moves downward so that the side plate is located on the flip plate 202. Then, the flip plate 202 is rotated 90 degrees so that the side plate becomes vertical. Then, the first horizontal linear mechanism drives the support frame 201 to move toward the center of the worktable 100 until the vertical side plate abuts against the horizontal side plate. Then, the support frame 201 is moved away from the center of the worktable 100. The same principle applies to the conveying and flipping of the bottom plate.

[0036] Specifically, such as Figures 6-8 As shown, the workbench 100 has through slots 108 at both ends along its length and on the side away from the limiting strip 103. The lower end of the flip plate 202 is located in the through slot 108 and is mounted on the first rotating shaft 203 at a right angle. It is provided with a first tooth 204. The first rotating shaft 203 is rotatably mounted on the support frame 201. The first tooth 204 meshes with the first drive gear 205. The first drive gear 205 is mounted on the first transmission shaft 206. The first transmission shaft 206 is rotatably mounted on the support frame 201 and connected to the output end of the first power device. The first power device is mounted on the support frame 201. After the bottom plate or side plate is located on the flip plate 202, the first power device drives the first transmission shaft 206 to rotate. Under the meshing transmission of the first tooth 204 and the first drive gear 205, the flip plate 202 will be rotated, thereby flipping the bottom plate or side plate to a vertical state. Then, the flip plate 202 can be moved toward the center of the workbench 100.

[0037] More specifically, such as Figure 6 As shown, a baffle 213 is provided on the side of one of the flip plates 202 away from the limiting bar 103. When the base plate is in a horizontal state, the baffle 213 will abut against the base plate to prevent the base plate from moving further. It can also limit one end of the base plate to prevent the base plate from shifting during assembly, ensuring that the connecting holes between the base plate and the side plate can be aligned, ensuring the smooth progress of the assembly operation. After the assembly is completed, the support plate 101 is removed from above the workbench 100, and the base plate is flipped back to a horizontal state by the flip plate 202 and placed on the conveyor belt. At this time, the conveyor belt is moved upward to lift the assembled buffer frame until it is higher than the baffle 213, and then the buffer frame can be conveyed away.

[0038] Specifically, such as Figures 6-8As shown, due to the large weight of the assembled buffer frame and its center of gravity being located outside the short end of the flip plate 202, in order to ensure that the buffer frame can be flipped smoothly, two long slots 109 are provided on the worktable 100, respectively located outside the long slot 102 and with one end far from the limiting strip 103. A rotating plate 208 is provided in the long slot 109. The end of the rotating plate 208 far from the limiting strip 103 is rotatably mounted on the worktable 100 and is provided with a second tooth 209. The second tooth 209 is coaxially arranged with the first tooth 204 located on the same side and meshes with the second drive gear 210. The second drive gear 210 is mounted on the second transmission shaft 211. The second drive shaft 211 is rotatably mounted below the workbench 100 and connected to the output end of the second power device. The second power device is mounted below the workbench 100. After the assembly operation is completed, the support plate 101 is removed from above the workbench 100. Then, the first power device and the second power device are started simultaneously to drive the flipping plate 202 and the rotating plate 208 to start rotating at the same time, so as to smoothly realize the flipping operation of the buffer frame. After that, the buffer frame can be transferred to the conveyor belt by the horizontal movement of the flipping plate 202. After the buffer frame is flipped, the rotating plate 208 can be reversed by the second power device to reset it into the long groove 109.

[0039] Specifically, such as Figure 6 As shown, the workbench 100 has a groove 110 at one end away from the limit bar 103. During assembly, the base plate is located in the groove 110 and the side of the base plate abuts against the side of the groove 110. At this time, the base plate and the side plate are in contact with each other. In order to ensure that the rotating plate 208 can smoothly lift the buffer frame, a protrusion 212 is provided on the surface of the rotating plate 208. When the rotating plate 208 is in a horizontal state, the rotating plate 208 is flush with the bottom surface of the groove 110 and in contact with the side of the base plate, while the protrusion 212 is flush with the surface of the workbench 100 and in contact with the bottom surface of the side plate.

[0040] Specifically, such as Figure 2 , Figure 9As shown, the vertical material tubes 302 are all installed on the connecting plate 307. The connecting plate 307 has a horizontal bar 308 on its side, one end of which is connected to the lifting frame 301. The top rods 303 are all installed on the moving plate 309. The moving plate 309 is sleeved on the horizontal bar 308 and connected to the moving end of the second horizontal linear mechanism. The second horizontal linear mechanism is installed on the lifting frame 301. The vertical material tubes 302 have through slots 310 on their sides, which are used to pass through the moving plate 309. Internally threaded cylindrical pins are arranged vertically in sequence inside the vertical material tubes 302 and fall sequentially under their own weight. The pins are located on the side plates and bottom. After the plate is in the assembly position, the lifting frame 301 is moved downwards, and then the moving plate 309 is driven to move towards the side plate by the second horizontal linear mechanism. At this time, the push rod 303 will push the internal threaded cylindrical pin into the side plate, thereby connecting the two mutually perpendicular side plates. During the movement of the push rod 303, only the internal threaded cylindrical pin at the bottom of the vertical material tube 302 will be pushed. After the internal threaded cylindrical pin at the bottom is completely pushed out of the vertical material tube 302, the internal threaded cylindrical pin at the top will fall on the push rod 303. Then the push rod 303 will reset, and the internal threaded cylindrical pin will fall to the bottom of the vertical material tube 302.

[0041] Specifically, such as Figure 2 , Figures 9-10 As shown, one end of the jacking pipe 305 is connected to the mounting plate 311, which is connected to the moving end of the third horizontal linear mechanism. The third horizontal linear mechanism is mounted on the lifting frame 301. A side frame 312 is provided on the mounting plate 311, and multiple second rotating shafts 313 are rotatably mounted on the side frame 312. One end of each second rotating shaft 313 is connected to a rotating rod 306. The end of the rotating rod 306 near the support plate 101 extends beyond the jacking pipe 305, and the extension distance is no greater than the thickness of the end of the hexagonal head screw. The other end of the second rotating shaft 313 is connected to the output end of a third power device, which is mounted on the side frame 312. When connecting the side plate and the bottom plate, the third horizontal linear mechanism drives the mounting plate 311 to move towards the bottom plate. Since the rotating rod 306 does not interact with the hexagonal head screw... The internal hexagonal sockets are aligned, so the rotating rod 306 will first abut against the internal hexagonal head screw, and then continue to drive the mounting plate 311 to move until the internal hexagonal head screw abuts against the threaded hole of the bottom plate. At this time, the second rotating shaft 313 is driven to rotate by the third power device, and the mounting plate 311 also continues to move. Then the rotating rod 306 will enter the internal hexagonal socket of the internal hexagonal head screw to achieve the cooperation between the two until the top tube 305 abuts against the end of the internal hexagonal head screw. With the rotation of the rotating rod 306 and the movement of the mounting plate 311, the internal hexagonal head screw will be screwed into the bottom plate, thereby connecting the bottom plate and the side plate. After that, the mounting plate 311 can be reset. The presence of the top tube 305 can prevent the rotating rod from colliding with the internal hexagonal head screw in the horizontal material tube 304 during the rotation process.

[0042] Specifically, such as Figure 10 As shown, the outer end of the horizontal material tube 304 is provided with a T-shaped groove 314 arranged along its length to accommodate hexagonal head bolts. These bolts are arranged sequentially along the length of the tube and can be positioned by the T-shaped groove 314 to maintain a horizontal state. A push plate 315 is provided in the T-shaped groove 314 and is sleeved on a guide rod 316. One end of the guide rod 316 is connected to a support plate 317, which is mounted on the horizontal material tube 304. A third spring 318 is sleeved on the guide rod 316. The push plate 315 and the support plate 317 are connected at both ends respectively and are always in a stretched state. Under the action of the third spring 318, the push plate 315 always tends to move towards the inner end of the horizontal material tube 304, thereby continuously moving the hexagonal head screw towards the top tube 305. When it is necessary to place the hexagonal head screw into the horizontal material tube 304, the push plate 315 is manually pushed to further stretch the third spring 318. Then the hexagonal head screw can be placed into the horizontal material tube 304 from the T-slot 314.

[0043] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Obviously, those skilled in the art can make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention also intends to include these modifications and variations.
