[0019] like Figure 1-5 As shown, this utility model has the following three specific embodiments.

[0020] Example 1 This utility model provides a movement second axis assembly device, including a base 11, a support frame 12 fixedly connected to the top of the base 11, and a top plate 13 fixedly connected to the top of the support frame 12. It also includes a second axis mounting mechanism 2, a quantitative feeding mechanism 3, and a second wheel clamping mechanism 4; The second axis mounting mechanism 2 is used to assemble the second axis; The quantitative feeding mechanism 3 is located on the rear side of the second shaft mounting mechanism 2 and is used to supply the second shaft to the second shaft mounting mechanism 2; The second wheel clamping mechanism 4 is located inside the base 11 and is used to clamp and position the second wheel.

[0021] In this embodiment, as Figure 1 As shown, the second shaft is first placed inside the quantitative feeding mechanism 3 and the second shaft is tidied up by the quantitative feeding mechanism 3. Then the second wheel is placed on the second wheel clamping mechanism 4 and centered and clamped. Then the second shaft in the quantitative feeding mechanism 3 is transported to the second shaft installation mechanism 2. Then the second shaft installation mechanism 2 is activated to insert the second shaft into the second wheel, thereby realizing the rapid assembly of the second shaft.

[0022] Example 2 The difference from Embodiment 1 is that this embodiment discloses a quantitative feeding mechanism 3 and a second wheel clamping mechanism 4; Preferably, the quantitative feeding mechanism 3 includes a lower support 31, which is fixedly connected to the top of the top plate 13. An upper support 32 is fixedly connected to the top of the lower support 31. A feeding hopper 33 is fixedly connected inside the upper support 32. A feeding plate 34 is fixedly connected to the bottom of the feeding hopper 33. A through hole is provided at the connection between the feeding plate 34 and the feeding hopper 33. A feeding wheel 35 is rotatably connected to the bottom of the feeding plate 34. Through holes are provided in a circular array inside the feeding wheel 35.

[0023] The second wheel clamping mechanism 4 includes a placement platform 41, which is fixedly connected to the top of the base 11.

A connecting rod 46 is hinged to the bottom of the slider 44. The end of the connecting rod 46 is hinged to the surface of the turntable 42.

[0024] A screw sleeve 47 is fixedly connected to the bottom of the rear slider 44. A screw rod 48 is connected to the internal thread of the screw sleeve 47. The screw rod 48 is rotatably connected to the inside of the base 11. A rocker handle 49 is fixedly connected to the end of the screw rod 48.

[0025] In this embodiment, as Figure 2-4 As shown, by feeding the second shaft into the hopper 33, and then starting the stepper motor 39 to drive the feeding wheel 35 to rotate at a certain angle, the second shaft inside the hopper 33 falls into the feeding wheel 35 through the feeding plate 34. Then, as the stepper motor 39 drives the feeding wheel 35 to rotate, the second shaft inside the feeding wheel 35 passes through the unloading plate 36 and falls into the guide box 37 for guidance. Then it is conveyed through the feeding pipe 38 and enters the feeding pipe 203 from the feeding port 206. Then the second wheel is placed on the placement table 41. Then the rocker arm 49 is turned to drive the screw 48 to rotate. The screw 48 moves inside the screw sleeve 47, thereby driving the slider 44 to slide inside the slide groove 43. At the same time, the slider 44 drives the turntable 42 to rotate through the connecting rod 46, thereby realizing the synchronous movement of multiple sliders 44, thereby clamping the second wheel and determining its center position.

[0026] Example 3 The difference from Embodiment 2 is that this embodiment discloses a second axis mounting mechanism 2; Preferably, the second axis mounting mechanism 2 includes a cylinder 201, which is fixedly connected to the top of the top plate 13. The output end of the cylinder 201 is fixedly connected to a sleeve 202 through the top plate 13. A feed pipe 203 is inserted into the inside of the sleeve 202. A limiting groove 204 is formed on the surface of the feed pipe 203. The sleeve 202 is slidably connected inside the limiting groove 204. A spring 205 is fixedly connected to the top of the feed pipe 203. The top of the spring 205 is fixedly connected to the top of the inner wall of the sleeve 202. A feeding port 206 is formed on the rear side of the feed pipe 203.

[0027] The bottom of the feed pipe 203 is fixedly connected to the outer shell 207. The inner wall of the outer shell 207 is hinged to the front and rear sides of the baffle 208. The surface of the baffle 208 is fixedly connected to the V-shaped spring 209. The V-shaped spring 209 is fixedly connected to the surface of the outer shell 207. The bottom of the outer shell 207 is fixedly connected to the discharge port 210. The inside of the sleeve 202 is fixedly connected to the push rod 211, which is inserted into the inside of the feed pipe 203.

[0028] In this embodiment, as Figure 5 As shown, by starting the cylinder 201, the cylinder 201 is pushed downward. When the feed port 210 contacts the second wheel, it continues to be pushed downward. At this time, the feed pipe 203 will be inserted into the sleeve 202. At the same time, the spring 205 is compressed. As the cylinder 201 continues to push, the push rod 211 pushes the second axis to move into the second wheel, thereby performing the assembly operation. After the assembly is completed, the cylinder 201 is lifted upward, the spring 205 rebounds and drives the feed pipe 203 to reset, thus facilitating the next assembly.

[0029] The working principle of this utility model is as follows.

[0030] By feeding the second shaft into the hopper 33, and then starting the stepper motor 39 to drive the feeding wheel 35 to rotate at a certain angle, the second shaft inside the hopper 33 falls into the feeding wheel 35 through the feeding plate 34. Then, as the stepper motor 39 drives the feeding wheel 35 to rotate, the second shaft inside the feeding wheel 35 passes through the unloading plate 36 and falls into the guide box 37 for guidance. Then it is conveyed through the feeding pipe 38 and enters the feeding pipe 203 from the feeding port 206. Then the second wheel is placed on the placement table 41. Then the rocker arm 49 is turned to drive the screw 48 to rotate. The screw 48 moves inside the screw sleeve 47, thereby driving the slider 44 to slide inside the slide groove 43. At the same time, the slider 44 drives the turntable 42 to rotate through the connecting rod 46, thereby realizing the synchronous movement of multiple sliders 44, thereby clamping the second wheel and determining its center position. By activating cylinder 201, the cylinder 201 is pushed downward. When the feed port 210 contacts the second wheel, it continues to be pushed downward. At this time, the feed pipe 203 will be inserted into the sleeve 202. At the same time, the spring 205 is compressed. As the cylinder 201 continues to push, the push rod 211 pushes the second axis to move into the second wheel, thereby performing the assembly operation. After the assembly is completed, the cylinder 201 is lifted upward, the spring 205 rebounds and drives the feed pipe 203 to reset, thus facilitating the next assembly.
