[0020] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] refer to Figures 1-6 The intermediate shell bushing rocker arm automatic feeding and assembly machine shown in the figure includes a frame 1, on which a bushing feeding mechanism 2, a metal ring feeding mechanism 3, an intermediate shell positioning and clamping mechanism 4 and a rocker arm feeding mechanism 5 are sequentially arranged, and a material transfer mechanism 6 is arranged above the intermediate shell positioning and clamping mechanism 4 on the frame 1, and the material transfer mechanism 6 is used to transfer and press-fit bushings 11 and metal rings 12, and a manipulator 7 is arranged next to the rocker arm feeding mechanism 5 on the frame 1, and the output end of the manipulator 7 is fixedly connected to a clamping cylinder 701, and the bushing feeding mechanism 2 includes a vibrating loader 201, a dislocation cylinder 202, a feeding push plate 203 and a blocking seat 204, and the feeding push plate 203 and the blocking seat The material seat 204 is provided with a feed trough 205, and the feed trough 205 is arranged corresponding to the material channel of the vibrating loader 201. The piston rod of the offset cylinder 202 is fixedly connected to the loading push plate 203. The offset cylinder 202 is used to drive the loading push plate 203 to load a single part. The metal ring loading mechanism 3 and the rocker arm loading mechanism 5 have the same structure as the bushing loading mechanism 2. The material transfer mechanism 6 includes a two-axis moving module 601, a bushing pressure head 602, a bushing positioning rod 603, and a metal ring positioning pressure head 604. The bushing positioning rod 603 and the metal ring positioning pressure head 604 are provided with multiple vacuum adsorption holes 8, and the vacuum adsorption holes 8 are used to adsorb the bushing 11 or the metal ring 12.

[0022] The intermediate shell positioning and clamping mechanism 4 includes a translation cylinder 401, a slide 402, an intermediate shell positioning seat 403, a clamping cylinder 404 and a rocker arm pressing cylinder 405. The intermediate shell positioning and clamping mechanism 4 is used to position and clamp the intermediate shell 10. There are multiple clamping cylinders 404, and multiple clamping cylinders 404 are arranged around the intermediate shell positioning seat 403. The translation cylinder 401, the intermediate shell positioning seat 403 and the clamping cylinder 404 are all fixedly connected to the slide 402. The translation cylinder 401 is used to switch the cavity slide 402 between the loading and unloading station and the assembly station. The piston rod of the translation cylinder 401 is fixedly connected to the slide 402.

[0023] A locking cylinder is fixedly connected to the lower part of the frame 1, and a socket corresponding to the piston rod of the locking cylinder is provided on the slide 402. The locking cylinder is used to lock the position of the slide to provide good assembly accuracy.

[0024] The vibrating loader 201, the offset cylinder 202 and the material blocking seat 204 are all fixedly connected to the frame 1, and the loading push plate 203 is slidably connected to the material blocking seat 204. The material blocking seat 204 can not only guide the sliding of the loading push plate 204, but also block the bushing 11 in the feed trough on the material blocking seat 204 when sliding to load.

[0025] The bushing press head 602 and the metal ring positioning press head 604 are both fixedly connected to the moving platform of the two-axis moving module 601. The bushing positioning rod 603 is fixedly connected to the bushing press head 602. The bushing positioning rod 603 can be used to position the bushing 11 when taking material.

[0026] The multiple vacuum adsorption holes 8 on the bushing positioning rod 603 are evenly distributed on its side wall surface, which improves the adsorption effect on the bushing 11 and prevents falling; the multiple vacuum adsorption holes 8 on the metal ring positioning pressure head 604 are evenly distributed in its positioning groove, which improves the adsorption effect on the metal ring 12 and prevents falling.

[0027] A barcode scanning cylinder 9 is fixedly connected to the side of the intermediate shell positioning and clamping mechanism 4 on the frame 1, and a barcode scanner 901 is fixedly connected to the movable platform on the barcode scanning cylinder 9. Before assembly and clamping, the barcode on the intermediate shell 10 is scanned to ensure that the assembled intermediate shell is correct.

[0028] The working principle of the present invention is as follows: the bushing 11 is loaded through the bushing loading mechanism 2, the metal ring 12 is loaded through the metal ring loading mechanism 3, and the rocker arm 13 is loaded through the rocker arm loading mechanism 5. Before assembly, the translation cylinder 401 first drives the slide 402 to slide to the loading station, and the intermediate shell 10 is placed along the positioning groove on the intermediate shell positioning seat 403. Then the slide 402 is reset, the piston rod of the code scanning cylinder 9 is extended, and the code scanner 901 scans the code. After the code information is correct, the pressing cylinder 404 presses the intermediate shell 10, and then the material transfer mechanism 6 simultaneously loads the material from the bushing. Mechanism 2 and metal ring feeding mechanism 3 absorb the bushing 11 (the bushing 11 is cylindrical) and the metal ring 12 (the metal ring 12 is a ring-mounted part) and transfer them to the top of the intermediate shell 10, and then press them vertically downward to press them onto the intermediate shell 10. Then, the manipulator 7 drives the gripper cylinder 701 to clamp the sheet metal part of the rocker arm 13 from the rocker arm feeding mechanism 5 (the rocker arm 13 can be regarded as a sheet metal part with a Z-shaped cross-section, with cylinders at both ends) and transfer it to the intermediate shell 10, and extend it into the middle section of the intermediate shell and pre-assemble it in the bushing 11 from bottom to top. Then, the manipulator 7 resets, and the rocker arm 13 is completely pressed into and assembled through the rocker arm pressing cylinder 405.

[0029] The above embodiments are used to further illustrate the present invention, but do not limit the present invention to these specific embodiments. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention should be understood to be within the scope of protection of the present invention.
