[0003] The existing metal shaft tube and plastic sleeve are generally assembled by mechanized equipment. However, after the existing automated equipment is assembled, it is unloaded by an additional electric push rod.

In addition, during unloading, the end face of the unloaded metal shaft tube may fall onto the unloading track. The contact area of ​​the end face of the metal shaft tube is large, resulting in large friction, and it cannot slide smoothly along the unloading track. Auxiliary unloading is required, which is inconvenient to operate. At the same time, there is a gap between the unloading track and the processing table during unloading, which can easily cause the workpiece to get stuck.

A feeding electric push rod 24 is installed inside the sleeve conveying track 22 and the metal shaft tube conveying track 23, and a slide plate 242 is installed at the end of the feeding electric push rod 24, and a sleeve 243 is slid inside the sleeve conveying track 22, and a metal shaft tube 244 is slid inside the metal shaft tube conveying track 23, and the sleeve 2 43 and the metal shaft tube 244 are fitted with the corresponding slide plate 242, and a stamping electric push rod 25 is installed above the discharge hole 221, and a stamping head 251 is installed at the end of the stamping electric push rod 25; start the feeding electric push rod 24, and then the slide plate 242 at the end can be driven to move, and the slide plate 242 can drive the workpiece that falls into the metal shaft tube conveying track 23 and the sleeve conveying track 22 to slide. In the process of the slide plate 242 pushing and sliding, the sleeve 243 on the sleeve conveying track 22 can slide smoothly along the sleeve conveying track 22, and the sleeve 243 can be dropped through the discharge hole 221 at this time. At this time, the sleeve 243 falls to the metal shaft tube 244 on the metal shaft tube conveying track 23, and the two are in a state of preliminary socketing. Then the operator can start the stamping electric push rod 25, which drives the stamping head 251 at the bottom to move downward. The stamping head 251 squeezes the sleeve 243, and finally the metal shaft tube 244 and the sleeve 243 can be assembled together, achieving the purpose of assembly.

[0047] The unloading plate 3 is rotatably mounted on the notch 31 opened on the side wall of the metal shaft tube conveying track 23, and a blocking plate 311 is installed at the bottom of the notch 31.

The unloading plate 3 rotates and drives the rocker 441 to start rotating, and the rocker 441 starts to rotate toward the protrusion 432. When the rocker 441 and the protrusion 432 come into contact, the rocker 441 pushes the protrusion 432 to move, and the protrusion 432 slides on the side wall of the rocker 441. The entire protrusion 432 starts to slide toward the side of the lower material track 13, thereby driving the connected positioning rod 431 to move. At this time, the positioning rod 431 can drive the synchronous plate 43 to slide. During the sliding process of the synchronous plate 43, the pull rod 42 can be driven to drive the push plate 4 to move toward the assembled workpiece. At this time, the workpiece is affected The force slides toward the notch 31, but after sliding a certain distance, the bottom of the workpiece is blocked by the blocking plate 311, but the top of the workpiece is still pushed by the push plate 4, and then the workpiece will be deflected at this time, and finally the workpiece will flip over, so that the arc surface of the side wall of the workpiece can fall onto the unloading track 13, reducing the contact surface area, so that it can automatically roll down and unload, avoiding the end face of the workpiece from falling on the unloading track. The friction force of the contact surface is large and it is stuck, and manual unloading is required. Finally, the purpose of automatic unloading can be achieved.

[0049] like Figures 1 to 13As shown, in a specific embodiment, a control box 11 is installed at the bottom of the workbench 1, and four supporting legs 111 are installed at the bottom corners of the control box 11.

[0050] like Figures 1 to 13 As shown, further, a support frame 121 is installed on the outer shell of the oscillating feed tray body 12, and the support frame 121 is welded on the workbench 1, and a vertical pole 132 is installed on the workbench 1, and the top of the vertical pole 132 is connected to the bottom of the unloading track 13, and a receiving hopper 131 is installed on the workbench 1, and the receiving hopper 131 corresponds to the unloading end of the unloading track 13, and the support frame 121 and the vertical pole 132 both play a supporting effect, and the receiving hopper 131 is used to collect workpieces.

The mounting plate 223 is attached to the upper surface of the positioning table 2, and the mounting plate 223 and the positioning table 2 are screwed together by bolts, which facilitates later disassembly through the vertical plate 222 and the mounting plate 223.

[0054] Embodiment 3:

[0055] The difference between Example 2 and this example is that: Figures 1 to 13As shown, further, a synchronous shaft 312 is installed at the rotation center of the unloading plate 3, a fixed seat 313 is installed at the top of the metal shaft tube conveying track 23, the synchronous shaft 312 is rotatably connected with the fixed seat 313, a guide seat 442 is sleeved on the outer wall of the synchronous shaft 312, and the guide seat 442 is installed at the bottom of the metal shaft tube conveying track 23, and the end of the synchronous shaft 312 is connected to the rotation center of the rocker 441. The swing arm 32 is provided with a strip groove 321, and a slide bar 333 is slidably installed inside the strip groove 321. The diameter of the slide bar 333 is adapted to the width of the strip groove 321, and the end of the slide bar 333 is connected to the side wall of the push rod 33. During the sliding of the connecting rod 332, the connecting rod 332 can drive the synchronous bracket 331 to slide at this time, and the synchronous bracket 331 drives the push rod 33 to move as a whole. The slide bar 333 on the push rod 33 slides inside the strip groove 321 of the swing arm 32, and the swing arm 32 rotates synchronously at this time. The swing arm 32 drives the synchronous shaft 312 to rotate on the fixed seat 313. After the synchronous shaft 312 rotates, the unloading plate 3 on the synchronous shaft 312 flips synchronously, and the end of the unloading plate 3 will eventually overlap on the unloading track 13, so that the unloading track 13 and the metal shaft tube conveying track 23 are connected together, which is convenient for later unloading.

[0056] like Figures 1 to 13 As shown, the side wall of the metal shaft tube conveying track 23 is sleeved with a positioning sleeve 34, and a pressing plate 342 is slidably installed inside the positioning sleeve 34, and the pressing plate 342 is connected to the connecting rod 332 and the extrusion block 341, and the connecting rod 332 is movably plugged with the positioning sleeve 34, and a compression spring 343 is sleeved with the side wall of the connecting rod 332, one end of the compression spring 343 is clamped on the pressing plate 342, and the other end of the compression spring 343 is clamped on the side wall of the positioning sleeve 34. When the feeding electric push rod 24 is reset to the end, the side wall of the slide plate 242 at the end of the feeding electric push rod 24 will squeeze the extrusion block 341, and the extrusion block 341 will shrink after being squeezed, and the extrusion block 341 will slide into the inside of the positioning sleeve 34, and the extrusion block 341 drives the pressing plate 342 and the connecting rod 332 to slide, and the compression spring 343 on the side wall of the connecting rod 332 is synchronously compressed, and the compression spring 343 is convenient for the later reset operation.

[0057] like Figures 1 to 13As shown, in a specific embodiment, a mounting groove 41 is provided on the inner side wall of the metal shaft tube conveying track 23, and the mounting groove 41 and the push plate 4 are adapted to each other, and the push plate 4 corresponds to the upper half of the discharge plate 3, and a reset plate 421 is installed at the connection between the pull rod 42 and the synchronous plate 43, and a reset spring 422 is sleeved on the pull rod 42, and one end of the reset spring 422 is clamped on the reset plate 421, and the other end is clamped on the outer side wall of the metal shaft tube conveying track 23. During the sliding process of the synchronous plate 43, the synchronous plate 43 can drive the reset plate 421 to move, and at this time, the reset plate 421 moves toward the side wall of the metal shaft tube conveying track 23, thereby compressing the reset spring 422 between the two, and facilitating the later reset through the reset spring 422.

[0058] like Figures 1 to 13 As shown, further, a limit rod 433 is installed in the synchronization plate 43, one end of the limit rod 433 is installed on the outer wall of the metal shaft tube conveying track 23, and a limit plate 434 is installed on the other end of the limit rod 433, and the diameter of the limit plate 434 is larger than the diameter of the limit rod 433. When the synchronization plate 43 slides, the synchronization plate 43 can slide on the limit rod 433, and the limit rod 433 is used to limit the synchronization plate 433, and the limit plate 434 at the end of the limit rod 433 ensures that the limit rod 433 and the synchronization plate 433 will not separate.

[0059] The implementation principle of the metal shaft tube and plastic sleeve assembly device of the present invention is as follows:

[0060] When the metal shaft tube and the plastic sleeve need to be assembled, the operator places the metal shaft tube 244 and the sleeve 243 on the corresponding oscillating feed tray body 12 respectively, and starts the oscillating feed tray body 12. The metal shaft tube 244 and the sleeve 243 can be continuously conveyed by the oscillating feed tray body 12, and the metal shaft tube 244 and the sleeve 243 can slide along the conveying guide rail 122 at this time, and finally convey the metal shaft tube 244 and the sleeve 243 to the corresponding metal shaft tube conveying track 23 and the sleeve conveying track 22. At the same time, by starting the feeding electric push rod 24, the slide plate 242 at the end can be driven to move, and the slide plate 242 can drive the workpieces that fall into the metal shaft tube conveying track 23 and the sleeve conveying track 22 to slide, such as Figure 4 shown.

[0061] During the sliding process of the slide plate 242, the sleeve 243 on the sleeve conveying track 22 can slide smoothly along the sleeve conveying track 22, and the sleeve 243 can be dropped through the feeding hole 221. At this time, the sleeve 243 drops to the metal shaft tube 244 on the metal shaft tube conveying track 23, and the two are in a preliminary sleeve connection state. Then the operator can start the stamping electric push rod 25, and the stamping electric push rod 25 drives the punching head 251 at the bottom to move downward, and the punching head 251 squeezes the sleeve 243, and finally the metal shaft tube 244 and the sleeve 243 can be assembled together, achieving the purpose of assembly.

[0062] Then the operator can start the reset of the feeding electric push rod 24 and the stamping electric push rod 25, and the reset feeding electric push rod 24 can eventually fall to the outside of the corresponding conveying track. At this time, the new metal shaft tube 244 and sleeve 243 move to the outside of the corresponding slide 242, which is convenient for the assembly operation of the next batch of workpieces.

[0063] When the feeding electric push rod 24 is reset to the end, the side wall of the slide plate 242 at the end of the feeding electric push rod 24 will squeeze the extrusion block 341. The extrusion block 341 shrinks after being squeezed, and the extrusion block 341 slides into the inside of the positioning sleeve 34. The extrusion block 341 drives the pressure plate 342 and the connecting rod 332 to slide. At this time, the compression spring 343 on the side wall of the connecting rod 332 is synchronously compressed, and the compression spring 343 is used to facilitate the subsequent resetting operation. During the sliding of the connecting rod 332, the connecting rod 332 can drive the synchronous bracket 331 to slide, and the synchronous bracket 331 drives the push rod 33 to move as a whole. The sliding rod 333 on the push rod 33 slides inside the bar groove 321 of the swing arm 32, and the swing arm 32 rotates synchronously at this time. The swing arm 32 drives the synchronous shaft 312 to rotate on the fixed seat 313. After the synchronous shaft 312 rotates, the unloading plate 3 on the synchronous shaft 312 flips synchronously, and the end of the unloading plate 3 will eventually overlap the unloading track 13, so that the unloading track 13 and the metal shaft tube conveying track 23 are connected together, reducing the gap during the unloading process and facilitating the later unloading.

[0064] During the rotation of the synchronous shaft 312, the synchronous shaft 312 also rotates on the guide seat 442, and the rocker 441 on the synchronous shaft 312 begins to rotate, and the rocker 441 begins to rotate toward the protrusion 432. When the rocker 441 and the protrusion 432 come into contact, the unloading plate 3 is now half opened. As the rocker 441 continues to rotate, the rocker 441 pushes the protrusion 432 to move, and the protrusion 432 slides on the side wall of the rocker 441. The entire protrusion 432 begins to slide toward the side of the lower material track 13, thereby driving the connected positioning rod 431 to move. At this time, the positioning rod 431 can drive the synchronous plate 43 to slide, and the synchronous plate 43 can slide on the limit rod 433 at this time. The limit rod 433 is used to limit the position, and the limit plate 434 at the end of the limit rod 433 ensures that the limit rod 433 and the synchronous plate 43 will not separate.

[0065] During the sliding of the synchronous plate 43, the synchronous plate 43 can drive the reset plate 421 to move. At this time, the reset plate 421 moves toward the side wall of the metal shaft tube conveying track 23, thereby compressing the reset spring 422 between the two, and facilitating the later reset through the reset spring 422. When the reset plate 421 slides, the reset plate 421 drives the pull rod 42 to move, and the pull rod 42 drives the push plate 4 to move toward the assembled workpiece. At this time, the workpiece is forced to slide toward the notch 31, but after sliding for a certain length, the bottom of the workpiece is blocked by the blocking plate 311, but the top of the workpiece is still pushed by the push plate 4, and then the workpiece at this time will be deflected, and finally the workpiece will flip over, so that the arc surface of the side wall of the workpiece can fall on the unloading track 13, reducing the contact surface area, so that it can automatically roll down and unload, avoiding the end face of the workpiece from falling on the unloading track. The friction of the contact surface is large and it is stuck, and manual unloading is required. Finally, the purpose of automatic unloading can be achieved.
