For example, it can be a fixed connection, an integral connection, or a detachable connection; it can be the internal connection of two components; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0036] See attached Figure 1-8 As shown, the connecting rod assembly component feeding mechanism of the embodiment of the utility model comprises a workbench 10 , on which a connecting rod feeding mechanism 11 and a bushing feeding mechanism 12 are provided.

[0037] See also Figure 3 As shown, the connecting rod loading mechanism 11 is located at the rear end of the workbench 10, and the connecting rod loading mechanism 11 includes a storage bin 101 and an inclined discharge plate 102 connected to the front end of the storage bin 101; the inclined discharge plate 102 is inclined toward the bracket 100 located on the workbench 10.

[0038] Referring to Figure 3-4, the storage bin 101 includes a left side plate 111, a right side plate 112, a front plate 113 at the front end, and an inclined bottom plate 114. The inclined bottom plate 114 is inclined downward relative to the horizontal. A longitudinal pneumatically controlled loading push plate 115 is provided between the front end of the inclined bottom plate 104 and the front plate 113. A pushing cylinder 117 is provided below the loading push plate 115 through a connecting block 116. The pushing cylinder 117 is arranged on the front plate 113 through a connecting plate 1171.

[0039] A left positioning plate 1111 and a right positioning plate 1121 are respectively provided on the inner sides of the left plate 111 and the right plate 112. The left positioning plate 1111 is pushed by a left sliding rod 118 passing through the left plate 111, and the right positioning plate 1111 is pushed by a right sliding rod 119 passing through the right plate 112.

[0040] When the connecting rods are located in the storage bin 101, the connecting rods are all accumulated at the front end of the storage bin 101 due to the inclination of the inclined bottom plate 114. When the feeding push plate 115 is pushed upward by the pushing cylinder 117, the connecting rods are immediately pushed to the inclined discharge plate 102. When the connecting rods in the storage bin 101 are disordered and uneven, the left sliding rod 118 and the right sliding rod 119 can be pushed to position the connecting rods from both sides of the left positioning plate 1111 and the right positioning plate 1121.

[0041] See also Figure 2 , 3 As shown, the bracket 100 is provided with a connecting rod positioning fixture 131 that is connected to the inclined discharge plate, and the connecting rod positioning fixture 131 includes a group of connecting rod positioning blocks 1311, and the group of connecting rod positioning blocks 1311 are connected to the front end of the inclined discharge plate 102. When the connecting rod is pushed to the inclined discharge plate 102, the connecting rod immediately falls into the group of connecting rod positioning blocks 1311 due to the inclination of the inclined discharge plate 102.

[0042] See also Figure 5 As shown, the bushing feeding mechanism 12 includes a feed trough 121, a push trough 122, and a bushing front and back side detection mechanism 123. The front end of the feed trough 121 is connected to the vibration plate, and the rear end of the feed trough 121 is connected to the push trough 122. One end of the push trough 122 is connected to the bushing front and back side detection mechanism 123. The other end of the push trough is provided with a pre-push cylinder 1221 which pushes toward the bushing front and back side detection mechanism 123. The bushing front and back side detection mechanism 123 is connected to the bushing flipping mechanism 1241.

[0043] The bushing that enters the feed trough 121 through the vibration plate is preset as a forward bushing. When the forward bushing enters the push trough 122, the pre-push cylinder 1221 pushes the forward bushing in the direction of the bushing front and back detection mechanism 123.

[0044] See also Figure 6 , 7As shown, the bushing front and back detection mechanism 123 includes a rear longitudinal plate 1231, a lower frame cover 1232 connected to the rear longitudinal plate 1231, and a front longitudinal plate 1233 corresponding to the rear longitudinal plate and located on the lower frame cover 1232. A gear rotating disk 1234 is embedded between the rear longitudinal plate 1231 and the front longitudinal plate 1233. The center of the gear rotating disk 1234 is a bushing through hole 1235. The front end of the bushing through hole 1235 is connected to the material pushing groove 122. A driving gear 1236 driven by the gear rotating disk 1234 through a belt 1235 is provided inside the lower frame cover 1232. The driving gear 1236 is connected to a driving cylinder 1237 located on the rear longitudinal plate 1231. At least two groups of optical fiber sensors 1237 are provided on the side of the rear longitudinal plate 1231 facing the front and back detection mechanism 123, and the optical fiber sensors 1237 sense the positive bushing pushed into the gear rotating disk 1234.

[0045] When the bushing enters the gear rotating disk 1234 of the bushing front and back side detection mechanism 123, the optical fiber sensor 1237 detects whether the bushing is a forward bushing. If it is a forward bushing, the bushing front and back side detection mechanism 123 does not operate, and the feeding continues under the propulsion of the pre-push cylinder 1221; when it is detected that the bushing entering the gear rotating disk 1234 is in the reverse direction, the driving cylinder 1237 drives the active gear 1236 to operate, and at this time the gear rotating disk 1234 drives the bushing to flip to the forward direction, and the pre-push cylinder 1221 promotes the feeding.

[0046] See also Figure 8 As shown, the bushing flipping mechanism 1241 includes a flipping frame 1242 arranged on the bracket 100, and a plurality of support plates 1243 arranged at equal intervals are arranged on the flipping frame 1242. A plurality of spiral flipping bars 1244 are arranged in the plurality of support plates 1243, and the spiral flipping bars 1244 are parallel and spirally penetrate the plurality of support plates 1243.

[0047] A bushing positive material positioning groove 132 is provided between the bushing front and back side detection mechanism 123 and the bushing flipping mechanism 1241, a bushing reverse material positioning groove 133 is provided at the end of the bushing flipping mechanism 123, a positive material pushing cylinder 1312 is provided on the bushing positive material positioning groove 132 at a position perpendicular to the forward direction of the bushing flipping mechanism 1241, and a reverse material pushing cylinder 1313 is provided on the bushing reverse material positioning groove 133 at a position perpendicular to the forward direction of the bushing flipping mechanism 1241.

[0048] When the positive bushing reaches the position of the bushing positive material positioning groove 132, the positive material pushing cylinder 1312 pushes the positive bushing into the rear end position of the bushing positive material positioning groove 132, and the bushing located behind the positive bushing enters the bushing flipping mechanism 1241. The multiple spiral flipping strips 1244 that penetrate the plurality of support plates 1243 flip the positive bushing in a mechanical twisting manner, so that the bushing reaching the bushing reverse material positioning groove 1303 is in a reverse state. At this time, the reverse material pushing cylinder 1313 pushes the reverse bushing into the rear end position of the bushing reverse material positioning groove 133. When the bushing in the bushing flipping mechanism 1241 is full and the bushing positive material positioning groove 132 is in an empty state, the forward bushing located at the bushing positive material positioning groove 132 is pushed into the rear end position of the bushing positive material positioning groove 132 again, and the rear bushing enters the bushing flipping mechanism 1241. When the front end bushing reverse material positioning groove 133 is in an empty state, the reverse material pushing cylinder 1313 pushes the bushing in again, and the cycle is repeated in sequence to realize that the forward and reverse bushings enter the bushing positive material positioning groove 132 and the bushing reverse material positioning groove 133 respectively, thereby realizing automatic loading.

[0049] The above shows and describes the basic principles of the present invention. The above are only preferred embodiments of the present invention and are not intended to limit the present invention. The above embodiments and descriptions in the specification are only intended to illustrate the principles of the present invention.
