Abstract
The invention relates to a fixed conveying roller bed which comprises a gear frame and a sleigh frame. Two parallel cross rods are arranged on the sleigh frame, the gear frame is provided with a chain wheel mechanism and two rows of transmission rollers, and the cross rods are in sliding fit with the transmission rollers. The sleigh frame is further provided with a set of locating holes, at least two air pumps are further mounted on the gear frame, and locating pins are arranged on the air pumps. At the machining assembly state of workpieces, the locating pins are inserted to the locating holes under the effect of the air pumps, and the sleigh frame is fixed. When the workpieces need to change stations, the locating pins are pulled out, and after the transmission rollers convey the sleigh frame to the new station, the locating pins bound up to locate the sleigh frame again. The fixed conveying roller bed is applied to the field of automobile production, and conveying of workpieces in station changing can be achieved.
Description
Technical field
The load transfer device field that the present invention relates to be welded, especially a kind of body in white part is fixedly welded transportation rolling-bed.
Background technology
Rolling bed is load transfer device conventional in automobile body-in-white welding process, is mainly used for carrying the movement of body in white part between different station, conversion station.Body in white part generally can be positioned in one and can roll on the ski rack sliding on bed, and body in white part moves rolling on bed with ski rack, to realize the conversion being welded between station.Because ski rack and to roll between bed be rolling friction transmission, exists delivery speed slow, carry the poor shortcoming of repeatable accuracy that puts in place.
Summary of the invention
Technical matters to be solved by this invention is, provides a kind of delivery speed fast, high fixing transportation rolling-bed of positioning precision.
Bed is rolled in the location that car production field is used, and comprises gear frame and ski rack, and ski rack is provided with two parallel cross bars, and gear frame is provided with chain-wheel mechanism and two row's transmission roller, cross bar and transmission roller bearing fits.Described ski rack is also provided with one group of knock hole, and described gear frame is also provided with at least two air pumps, and this air pump is provided with locating dowel pin.
Preferably, described gear frame is provided with one group of position sensor.
Preferably, described gear frame is provided with one group of guiding roller, and this guiding roller is located at the both sides of ski rack sense of motion.
The invention has the beneficial effects as follows: of the present invention fixing transportation rolling-bed can be quick and precisely for the body in white part being transferred positions, realizing ski rack carries at a high speed, when station spacing is 6 meters, the shortest time of delivery is only in 9 seconds, has effectively improved productive temp.
Accompanying drawing explanation
Fig. 1 be car production of the present invention field use location roll bed an embodiment master look schematic diagram;
Fig. 2 is the schematic side view of Fig. 1;
In figure, parts Reference numeral is: 100-gear frame, 101-transmission roller, 102-chain-wheel mechanism, 103-guiding roller, 110-air pump, 111-locating dowel pin, 120-ski rack, 121-knock hole, 122-support, 123-cross bar, 131-position sensor.
The specific embodiment
Below in conjunction with drawings and Examples, the present invention is further described: as depicted in figs. 1 and 2:
Bed is rolled in the location that car production field is used, and comprises gear frame 100 and ski rack 120, and ski rack 120 is provided with two parallel cross bars 123, and gear frame 100 is provided with chain-wheel mechanism 102 and two row's transmission rollers 101, cross bar 123 and transmission roller 101 bearing fits.Described ski rack 120 is also provided with one group of knock hole 121.And described gear frame 100 is also provided with at least two air pumps 110, and air pump 110 is provided with locating dowel pin 111.
Snow detector 131.Position sensor 131 can detect the position of ski rack 120, and adjusts transmission roller 101 velocities of rotation according to ski rack position, and controls air pump 110 folding and unfolding locating dowel pins 111, makes the time of finding accurately shorter, also more saves manpower.Sledge frame 120 is provided with the support 122 of fixing body in white.When body in white part is during in process and assemble process status, locating dowel pin 111 inserts the fixing ski rack 120 of knock hole 121, is body in white location.When body in white part completes a processing/assembly process and need to change station, air pump 110 effects make locating dowel pin 111 depart from knock hole 121, and transmission roller 101 rotates under the effect of chain-wheel mechanism 102, and drives ski rack 120 to move to next station.Now stop chain-wheel mechanism, air pump 110 is upspring in insertion knock hole 121 locating dowel pin 111, and body in white is located again.
In use procedure of the present invention, produce part and change station and realize by the movement of ski rack 120, and ski rack 120 often moves to new working position and need to reorientate for it and find accurately, thereby the locating dowel pin 111 ejecting is coordinated with knock hole 121, fix ski rack 120.In the present embodiment on gear frame 100 one group of position sensor 131.Roll bed according to the position signal detecting, control transport sector acceleration and deceleration or parking.Do so on the one hand and make ski rack 120 positioning precisions higher, also can allow on the other hand body in white transmit faster between station, when station spacing is 6 meters, the shortest time of delivery is only in 9 seconds, has effectively improved productive temp.
