[0049] Embodiment 3:

[0050] The difference between the above embodiment and this embodiment is that: Figures 1 to 10 As shown, a mounting seat 2041 is installed at the end of the guide rod 204, and a guide wheel 2042 is installed on the mounting seat 2041. The guide wheel 2042 is slidably connected with the guide track 2051. A limit seat 2043 is movably inserted on the guide rod 204, and the limit seat 2043 is installed on the turntable 102. A positioning spring 2044 is sleeved on the guide rod 204, and one end of the positioning spring 2044 is clamped on the side wall of the push plate 2032, and the other end of the positioning spring 2044 is clamped on the limit seat 2043. When the assembly shell 400 is assembled, the guide rod 204 corresponding to the clamp cover 201 will move to the notch 2052. At this time, the guide rod 204 is stretched by the positioning spring 2044, and then the guide rod 204 is pulled to move to the notch 2052, and the guide wheel 2042 on the guide rod 204 always slides on the guide track 2051, so as to play a guiding role.

[0051] like Figures 1 to 10 As shown, in a specific embodiment, a ball 3011 is installed on the top of the arch support 301, and slopes 3022 are provided at both ends of the extrusion track 302. A mounting bracket 3021 is installed on the extrusion track 302, and the mounting bracket 3021 is L-shaped. The bottom of the mounting bracket 3021 is installed on the support plate 101. A protective cover 206 is installed on the support plate 101, and the protective cover 206 covers the guide rod 204. A reset cover 303 is installed on the protective cover 206, and a baffle 3033 is slidably provided inside the reset cover 303. A reset rod 3031 is installed on the top of the baffle 3033, and the reset rod 3031 movably penetrates the reset cover 303, and the top of the reset rod 3031 and the bottom of the arch support 301 are connected to each other, and a reset spring 3032 is clamped between the bottom of the baffle 3033 and the reset cover 303, and the compression direction of the reset spring 3032 and the moving direction of the reset rod 3031 are located on the same straight line. As the guide rod 204 continues to slide in the notch 2052, the arch bracket 301 at the top moves to slide to the bottom of the extrusion track 302 through the slope 3022, and the ball 3011 on the arch bracket 301 slides under the extrusion track 302, playing a guiding role, and pushing the arch bracket 301 as a whole to move downward through the extrusion track 302, and the extrusion side rod 3012 and the lifting rod 3013 slide downward, and the new assembly shell on the lifting rod 3013 moves to the horizontal position of the clamp cover 201. When the guide rod 204 and the notch 205 After separation, the guide rod 204 can slide on the guide rail 2051, and the guide rod 204 squeezes the push rod 203 again to move, pushes the new assembly shell 400 into the clamping cover 201 and locks it, thereby completing the automatic loading operation. In the process of the arch bracket 301 sliding downward, the arch bracket 301 squeezes the reset rod 3031 to slide downward, and the reset rod 3031 drives the baffle 3033 to slide inside the reset cover 303, squeezing the reset spring 3032, and the reset spring 3032 facilitates the reset operation later.

[0052] The implementation principle of the assembly device of a precision metal component of this embodiment is as follows:

[0053] The device needs to cooperate with an assembly robot, and the assembly robot is a prior art and will not be described in detail here.

[0054] First, the operator needs to install the assembly housing 400 in the gap between the clamp cover 201 and the push rod 203 .

[0055] Then start the drive motor 103, and drive the transmission shaft 1031 to rotate through the drive motor 103, and the transmission shaft 1031 passes through the support plate 101 and the positioning gear ring 2022. Finally, the transmission shaft 1031 can drive the turntable 102 to rotate, and the four workstations on the turntable 102 can move synchronously to change the position of the clamped assembly shell 400, so as to facilitate different manipulators to perform assembly operations.

[0056] During the rotation of the turntable 102, the transposition gear 202 on the turntable 102 moves on the positioning gear ring 2022, and the transposition gear 202 itself will rotate while being covered with the positioning gear ring 2022. The transposition gear 202 drives the clamping cover 201 to rotate as a whole through the gear shaft 2021, and the clamping cover 201 can drive the clamped assembly shell 400 to rotate a certain angle, thereby changing the assembly position of the assembly shell 400, making the assembly operation simpler.

[0057] When the assembly shell 400 is assembled, the guide rod 204 corresponding to the clamp cover 201 will move to the notch 2052. At this time, the guide rod 204 is stretched by the positioning spring 2044, thereby pulling the guide rod 204 to move toward the notch 2052, and the guide wheel 2042 on the guide rod 204 always slides on the guide track 2051, thereby playing a guiding role.

[0058] When the guide rod 204 slides, the position of the push plate 2032 on the guide rod 204 changes synchronously, and the push plate 2032 slides along the slide rail 2033, driving the push rod 203 to slide on the horizontal groove 2034, and finally the push rod 203 and the top plate 2031 are separated from the assembly shell 400, achieving the purpose of automatic unlocking.

[0059] At the same time, the extrusion spring 2015 pulls the synchronous plate 2014 to slide outward, and the synchronous rod 2013 on the synchronous plate 2014 drives the extrusion plate 2012 to move outward as a whole, and then the extrusion plate 2012 drives the assembly shell 400 to move out of the clamp cover 201 as a whole, thereby achieving the purpose of automatic unloading.

[0060] As the guide rod 204 continues to slide in the notch 2052, the top arch bracket 301 moves to slide to the bottom of the extrusion track 302 through the ramp 3022, and the ball 3011 on the arch bracket 301 slides under the extrusion track 302, playing a guiding role, and pushing the arch bracket 301 as a whole to move downward through the extrusion track 302, and the extrusion side rod 3012 and the lifting rod 3013 slide downward, and the new assembly shell on the lifting rod 3013 moves to the horizontal position of the clamping cover 201. When the guide rod 204 and the notch 2052 are separated, the guide rod 204 can slide on the guide track 2051. At this time, the guide rod 204 re-extrudes the top rod 203 to move, pushes the new assembly shell 400 into the clamping cover 201 and locks it, thereby completing the automatic loading operation, reducing the workload of later manual auxiliary operations, and improving assembly efficiency.

[0061] When the arch bracket 301 slides at the bottom of the extrusion track 302, the transposition gear 202 and the positioning gear ring 2022 are in contact at a position where there are no teeth, and thus the transposition gear 202 does not rotate, ensuring that the angle position of the clamping cover 201 does not change at this time, making it convenient for a new assembly shell 400 to be plugged into the inside of the clamping cover 201 later.

[0062] When the arch support 301 slides downward, the arch support 301 squeezes the reset rod 3031 to slide downward, and the reset rod 3031 drives the baffle 3033 to slide inside the reset cover 303, squeezing the reset spring 3032, so that the reset operation can be performed later.
