In some embodiments, as shown in fig. 5, the caster placing seat includes a caster placing plate 210, a first caster placing groove 211 is provided on the top surface of the caster placing plate 210, the bottom plate of the caster is placed in the first caster placing groove 211, the first caster placing groove 211 is used for positioning the bottom plate of the caster, a caster positioning column 220 which can elastically stretch in the vertical direction is provided in the first caster placing groove 211, and the caster positioning column 220 is inserted into a riveting hole on the bottom plate of the caster to secondarily position the bottom plate of the caster. Because the truckle reference column 220 is elastically telescopic, at the in-process of placing the rivet, the rivet can extrude the truckle reference column 220 for truckle reference column 220 contracts, just so can not take place to interfere with the rivet, and truckle reference column 220 can be made longer, can all fix a position parts such as truckle bottom plate, upper cover plate and support, has promoted the positioning effect. Meanwhile, the rivet is subjected to the jacking force of the caster positioning column 220 in the process of placing the rivet into the riveting hole, so that the rivet is not easy to shake and can be stably and accurately inserted into the riveting hole.

In some embodiments, a first through hole penetrating the caster placement plate 210 in the vertical direction is provided in the first caster placement groove 211, and a positioning sleeve 230 abutting the first through hole is fixed to the bottom surface of the caster placement plate 210, and the positioning sleeve 230 may be coaxially disposed with the first through hole. The caster positioning column 220 passes through and is movable in the first pass-through hole, and the lower end of the caster positioning column 220 is positioned in the positioning sleeve 230, and the caster positioning column 220 is also movable along the positioning sleeve 230. A first elastic restoring member (not shown) abutting the caster positioning column 220 is provided in the positioning sleeve 230, which allows the caster positioning column 220 to elastically expand and contract. The positioning sleeve 230 plays a guiding role on the caster positioning column 220, so that the caster positioning column 220 keeps elastic expansion and contraction along the vertical direction.

Further, the lower end of the positioning sleeve 230 is detachably fixed with a sleeve cover 231, and two ends of the first elastic restoring member are respectively abutted against the caster positioning column 220 and the sleeve cover 231, so as to apply an elastic restoring force along the vertical direction to the caster positioning column 220, so that the caster positioning column 220 is elastically stretched along the vertical direction. Meanwhile, since the sleeve cap 231 is detachably fixed to the lower end of the positioning sleeve 230, the caster positioning column 220 and the first elastic restoring member can be conveniently assembled in the positioning sleeve 230.

The rivet transverse moving mechanism 1140 is used for driving the rivet vertical moving mechanism 1150 to move transversely, and accordingly can drive the bottom plate clamp 1170 and the rivet clamp 1180 to move transversely, the rivet vertical moving mechanism 1150 is used for driving the rivet vertical moving mechanism 1160 to move vertically, and accordingly can drive the bottom plate clamp 1170 and the rivet clamp 1180 to move vertically, and the rivet vertical moving mechanism 1160 is used for driving the bottom plate clamp 1170 and the rivet clamp 1180 to move longitudinally, so that the bottom plate clamp 1170 and the rivet clamp 1180 can move transversely, longitudinally and/or vertically, and the bottom plate clamp 1170 and the rivet clamp 1180 can be close to a target position through the mutual coordination of the rivet transverse moving mechanism 1140, the rivet vertical moving mechanism 1150 and/or the rivet vertical moving mechanism 1160, and further the bottom plate clamp 1170 clamps the bottom plate of the caster or releases the bottom plate, and the rivet clamp 1180 clamps the rivet or releases the rivet.

The specific working principle is as follows: the rivet conveying component 1110 firstly conveys rivets to the rivet buffer seat 1120 to buffer the rivets in the rivet buffer seat 1120, and under the mutual coordination of the rivet transverse moving mechanism 1140, the rivet vertical moving mechanism 1150 and/or the rivet vertical moving mechanism 1160, the rivet clamp 1180 is close to the rivet buffer seat 1120, so that the rivet clamp 1180 can clamp the rivets on the rivet buffer seat 1120; then, the rivet transverse moving mechanism 1140, the rivet vertical moving mechanism 1150 and/or the rivet longitudinal moving mechanism 1160 further act, so that the rivet clamp 1180 moves above the caster with the rivet, and then the rivet is inserted into the riveting hole on the caster, and the rivet clamp 1180 releases the clamped rivet, thereby completing the assembly of the rivet. Therefore, automatic assembly of rivets can be realized, and the production efficiency is effectively improved.

After the assembly of the rivet is completed, the bottom plate clamp 1170 clamps the bottom plate of the caster so that the entire caster assembled with the rivet can be moved, and the caster assembled with the rivet is moved to another station under the coordinated cooperation of the rivet lateral movement mechanism 1140, the rivet vertical movement mechanism 1150 and/or the rivet longitudinal movement mechanism 1160, and the bottom plate clamp 1170 releases the bottom plate again so as to rivet the rivet at the other station.

The rivet clamp 1180 is disposed between the two base plate clamping jaws 1172, because the center position of the base plate is provided with a riveting hole, the rivet clamp 1180 needs to insert a rivet into the riveting hole, and the position relationship between the rivet clamp 1180 and the two base plate clamping jaws 1172 can adapt to the actual structure of the caster, so that the requirement of assembly work is met. Meanwhile, after the rivet is assembled in place and the rivet clamp 1180 releases the rivet, the bottom plate clamp driving mechanism 1171 can immediately drive the two bottom plate clamping jaws 1172 to clamp the bottom plate, so that the bottom plate is transferred to the next station, and the waiting time is reduced due to the position relationship between the rivet clamp 1180 and the two bottom plate clamping jaws 1172, so that clamping actions of the clamps are more consistent, and the working efficiency can be further improved.

The clamping direction of the bottom plate clamping jaw 1172 is perpendicular to the clamping direction of the rivet clamping jaw 1182, so that the rivet clamping jaw 1182 can avoid a bracket on a caster, and the bottom plate clamping jaw 1172 and the rivet clamping jaw 1182 can be prevented from interfering with each other, so that the two clamps can work independently and smoothly.

Further, the inner sides of the two base plate clamping claws 1172 are provided with base plate clamping blocks 1173, and the inner sides of the base plate clamping blocks 1173 are provided with base plate clamping grooves 1174 for the base plate to be embedded.
