Description

A hub flap type pre-cleaning line automatic transmission device

technical field

The invention relates to the production of motor vehicle parts, in particular to the processing of wheel hubs.

Background technique

At present, in the field of wheel hub production, pre-cleaning is to eliminate oil stains and dust accumulation on the surface of the hub after machining, and is an indispensable process before painting. In order to ensure the cleaning effect, the parts are transported by a suspended conveyor line, that is, the hub is in a vertical state during cleaning.

The method of manual loading and unloading is labor-intensive and low in production efficiency, which does not meet the needs of automated production. If a robot is used to realize the upper and lower parts of the suspension chain, on the one hand, the equipment investment is large, and on the other hand, the accuracy of the suspension chain cannot match the requirements of the robot.

Contents of the invention

The technical problem solved by the invention is: how to realize the automatic transmission of wheel hub pre-cleaning mixed line production simply and efficiently.

In order to solve the above technical problems, the present invention provides the following technical solutions: a hub flap type automatic transmission device for pre-cleaning line, including the front conveyor line, pre-cleaning conveyor line, and rear conveyor line connected in sequence; the pre-cleaning A flap is provided on the conveying line, a first flap give way structure is arranged on the front conveying line, and a second flap give way structure is arranged on the rear conveying line.

According to the above-mentioned technical scheme, the hub is placed horizontally on the front conveyor line to the rear end of the front conveyor line, and the flap that moves circularly along with the pre-cleaning conveyor line goes deep into the first flap of the front conveyor line to give way to the structure. And upwards pass through the first turnover plate to give way to the structure, and the wheel hub on the front conveying line is picked up and erected. On the pre-cleaning conveyor line, the upright hubs are cleaned. The wheel hub on the pre-cleaning conveying line runs to the rear end of the pre-cleaning conveying line, and the flap goes deep into the second flap give way structure of the rear conveying line, and passes through the second flap let go structure downwards, while the hub stays in the On the subsequent conveying line, it is transported to the predetermined destination by the latter conveying line.

In order to form the above-mentioned first turnover structure, the front conveying line of the present invention adopts a roller conveying body with a double-row structure. Similarly, in order to form the above-mentioned second turnover structure, the rear conveying line of the present invention also adopts a double-row structure of the roller conveying body. The turnover plate of circular circulation passes through the gap in the middle of the double-row structure roller transmission body.

There are two groups of photoelectric sensors on the front conveying line, the hub passes through the first group of photoelectric sensors, the front conveying line decelerates, the wheel hub passes through the second group of photoelectric sensors, and the front conveying line stops, so that the turning plate can be moved by Pick up the hub from the bottom up.

The invention can complete the automatic and precise conveying during the hub pre-cleaning mixed-line processing, can be seamlessly connected with the automatic transmission line of the previous process, has simple control and reliable operation. Greatly improve production efficiency and reduce labor intensity of workers.

Detailed ways

Referring to Fig. 1 and Fig. 2, an automatic transmission device for a wheel hub flap type pre-cleaning line includes a front conveyor line 10, a pre-cleaning conveyor line 20, and a rear conveyor line 30 connected in sequence.

As shown in FIG. 2 , the preceding conveying line 10 includes a first roller conveying line body 11 and two groups of photoelectric sensors arranged thereon. The first roller transmission line body adopts a double-row structure, and the gap (greater than 150mm) between the two rows of roller transmission line bodies constitutes the first flap give way structure 100 .

Two groups of photoelectric sensors are respectively the first group of photoelectric sensors and the second group of photoelectric sensors. The two photoelectric sensors in the first group of photoelectric sensors are arranged on both sides of the first roller transmission line body 11, and the two photoelectric sensors in the second group of photoelectric sensors Two photoelectric sensors are arranged on both sides of the first roller transmission line body 11 .

As shown in FIG. 2 , the rear conveying line 30 includes a second roller transmission line body 31 , the second roller transmission line body adopts a double-row structure, and the gap (greater than 150mm) between the two rows of roller transmission line bodies constitutes a second flap give way structure 300 .

Referring to FIG. 1 and FIG. 2 , the pre-cleaning conveying line 20 includes a conveying line body 21 , a conveying chain 22 assembled on the conveying line body, and the conveying chain 22 is driven by a motor 23 .

Several pairs of convex flaps 40 are fixed on the conveyor chain 22 , and the distance between any pair of flaps is equal to or slightly greater than the axial thickness of the hub 50 .

Referring to Fig. 3, the flap 40 is welded by SUS304 stainless steel square tube, the convex flap includes a wide part 42 and a narrow part 41, the narrow part is the hub support part, the width of this part is smaller than the first drum transmission line The first turnover structure 100 on the body 11 is also smaller than the second turnover structure 300 on the second roller transmission line body 31, that is, less than 150mm, and the total length of the turnover is not less than 360mm. Wherein, the wide part of the turning plate is convenient for supporting the wheel hub and improves the stability of the wheel hub on the pre-cleaning conveying line 20 .

In actual operation, the hub 50 is placed horizontally on the front conveyor line 10, the hub passes through the first group of photoelectric sensors 12, the front conveyor line decelerates, the hub passes through the second group of photoelectric sensors 13, and the front conveyor line pauses , the hub stays at the junction of the previous conveying line 10 and the pre-cleaning conveying line 20 .

The turnover plate 40 moving from bottom to top passes through the gap between the two rows of roller transmission line bodies of the previous conveying line 10, and picks up the hub, which is located between a pair of turnover panels. Along with the operation of the pre-cleaning conveying line 20 , the hub gradually turns to an upright state and is cleaned on the pre-cleaning conveying line 20 .

The wheel hub that moves with the pre-cleaning conveyor line 20 reaches the connection between the rear conveyor line 30 and the pre-cleaning conveyor line 20, and the flip plate 40 that moves from top to bottom passes through the gap between the two rows of rollers on the rear conveyor line 30. Stay and lay flat on the rear conveying line 30.

The above content is only the preferred implementation mode of the present invention. For those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation mode and application scope. limits.
