Described drive mechanism includes a servo deceleration motor, and the output shaft of servo deceleration motor is provided with gear;The outside of described mill material plate is provided with tooth bar, and wheel and rack engages, the rotating of servo deceleration motor, thus is moved back and forth by gear, rack drives mill material plate, drives whole reciprocating lever mechanism to move back and forth;
The top of the support column of servo deceleration motor both sides is provided with contact roller mounting blocks, and contact roller mounting blocks is provided with contact roller, and contact roller is positioned at the top supporting wheel, contact roller and the support wheel common constraint mill material plate degree of freedom in Z-direction;
Being reserved with installing hole on described mill material plate, be provided with many connecting rods by installing hole between relative mill material plate, described connecting rod detachably and is replaced with flexible carrying supporting mechanism for location.
The both sides being positioned at contact roller on described contact roller mounting blocks are provided with iron wire hairbrush, and iron wire hairbrush is arranged on hairbrush installing plate.
The invention has the beneficial effects as follows:
The present invention is an important mechanism in auto body soldering product line, achieve the reciprocating action of the flexible detent mechanism of body of a motor car carrying, carry out carrying conveying after positioning tool is separated from by workpiece lifting for the load lifting cylinder that conveyance detent mechanism used in the past, greatly shorten the handling time of workpiece.
Accompanying drawing explanation
When considered in conjunction with the accompanying drawings, by referring to detailed description below, can more completely be more fully understood that the present invention and easily learn the advantage that many of which is adjoint, but accompanying drawing described herein is used for providing a further understanding of the present invention, constitute the part of the present invention, the schematic description and description of the present invention is used for explaining the present invention, is not intended that inappropriate limitation of the present invention, wherein:
Fig. 1 is the population structure schematic diagram of the present invention;
Fig. 2 is the A portion partial enlarged drawing in Fig. 1;
Fig. 3 is the structural representation of drive mechanism.
Detailed description of the invention
Below in conjunction with accompanying drawing to the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described.
Fig. 1 is the population structure schematic diagram of the present invention;Fig. 2 is the A portion partial enlarged drawing in Fig. 1;Fig. 3 is the structural representation of drive mechanism, go out as shown in Figure 1, Figure 2, Figure 3 shows, a kind of reciprocating lever mechanism of the automobile body welding production line of the present invention, for installing the flexible conveyance positioning mechanism in auto body soldering product line, including the support column 1 being disposed in pairs on each station, it is provided with support wheel mounting blocks 4 on each support column 1, supports and support wheel 5 is installed on wheel mounting blocks 4;The side supporting wheel mounting blocks 4 is provided with directive wheel gripper shoe 6, and directive wheel gripper shoe 6 is provided with directive wheel 7;Supporting to support on wheel 5 and have mill material plate 8, mill material plate 8 moves back and forth under the drive of drive mechanism in X direction;A pair directive wheel 7 constraint mill material plate 8 degree of freedom in the Y direction that directive wheel 7 is in the outside of mill material plate 8 and relative;
Described drive mechanism includes a servo deceleration motor 14, and the output shaft of servo deceleration motor 14 is provided with gear 15;The outside of described mill material plate 8 is provided with tooth bar 16, and gear 15 engages with tooth bar 16, the rotating of servo deceleration motor 14, thus drives mill material plate 8 to move back and forth by gear 15, tooth bar 16, drives whole reciprocating lever mechanism to move back and forth.
The top of the support column of servo deceleration motor 14 both sides is provided with contact roller mounting blocks 2, and contact roller mounting blocks 2 is provided with contact roller 3, and contact roller 3 is positioned at the top supporting wheel 5, and contact roller 3 grinds the material plate 8 degree of freedom in Z-direction with supporting wheel 5 constraint jointly,
Contact roller 3 is only provided in the both sides of servo deceleration motor 14, reason is that servo deceleration motor 14 can be to mill 8 one component upwards of material plate when operation, and the contact roller 3 near servo deceleration motor 14 can offset this component, ensure the precision position of mill material plate 8, be not provided with contact roller 3 at other stations.
Wherein, X-direction is the direction along mill material plate, and Y-direction is the closure of symmetrical directive wheel, and Z-direction is the direction vertical with X, Y.
The both sides being positioned at contact roller 3 on described contact roller mounting blocks 2 are provided with iron wire hairbrush 12, iron wire hairbrush 12 is arranged on hairbrush installing plate 13, effect is to have welding slag to fall on mill material plate when producing, the iron wire hairbrush 12 of contact roller 3 both sides can remove mill material plate on welding slag, it is ensured that mill material plate motion time with the relative position between contact roller.
Being reserved with installing hole 9 on described mill material plate 8, be provided with many connecting rods 10 by installing hole 9 between relative mill material plate 8, described connecting rod 10 is detachable and replaces with flexible carrying supporting mechanism for location 11.
Described embodiment is only a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of protection of the invention.
