Detailed Description
The invention provides a roller way conveying device for an automobile crankshaft, which is further described in detail below by referring to the attached drawings and embodiments in order to make the purpose, technical scheme and effect of the invention clearer and clearer. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the scope of the invention.
Referring to fig. 1 to 10, the roller conveyor for the automobile crankshaft sets the direction of the tray conveyed by the roller conveyor as "front" and the directions of the "front" and "rear" are opposite. The dotted line in the figure indicates the detection light emitted by the sensor and cannot be directly observed.
Roller table conveyor of car bent axle, including frame 1, two relative settings and be located the mount pad 2 of frame top both sides respectively, many deflector rolls 3 that set up between two mount pads, two kinds or more than can be by deflector roll transport's tray 4, control module 5 to and be used for driving all deflector rolls synchronous pivoted driving motor 61, be equipped with the identification module 43 of setting on preset position on every kind of tray 4, be provided with multiunit inductor 7 on the mount pad 2, every group inductor 7, driving motor 61 all with control module electric connection, these inductor 7 is used for responding to identification module 43 on the tray 4 and feeds back response information to control module 5.
When the automatic conveying device works, different types of trays can be conveyed into a roller way conveying device of the automobile crankshaft one by one through an upstream conveying device, the tray 4 is an empty tray at the moment, the crankshaft is not placed on the tray, and the automobile crankshafts of different types need to be loaded by special trays due to different shaft lengths of the automobile crankshafts of different types; driving motor 61 drive deflector roll 3 rotates, drives and places tray 4 on the deflector roll 3 moves to detecting station (the inductor can normally carry out the position that detects to the tray promptly), and identification module 43 can make partial inductor 7 produce sensing signal, and another part inductor 7 then can not produce sensing signal, and control module 5 can acquire all inductor 7's sensing signal this moment, and control module 5 obtains the testing result after the analysis. If N kinds of trays are provided, N kinds of detection results can correspondingly appear due to different setting positions of the identification modules on each kind of trays, and the N kinds of detection results are different; in addition, the tray may be placed correctly or placed reversely, so that the total of 2N detection results may appear by adding reversed detection results, and the 2N detection results are different from each other. Therefore, since each detection result is unique, the control module 5 can not only determine the type of the tray 4 from the detection result, but also detect whether the tray 4 is set upside down. When the control module 5 determines the type of the tray and the placing posture is correct, the control module 5 controls the mechanical arm to clamp the automobile crankshaft of the corresponding type onto the tray 4 of the detection station, and then the driving motor 61 drives the guide roller 3 to rotate to drive the tray 4 placed on the guide roller 3 to be conveyed forwards for manual quality inspection; when the control module determines that the tray is placed reversely, the control module 5 can send out a warning signal to inform an operator to place the tray 4 right again, so that the crankshaft can be correctly placed on the tray 4, and the automobile crankshaft can be smoothly matched with a downstream quality inspection device for quality inspection. Therefore, the roller way conveying device provided by the invention can intelligently identify the type and the placing posture of the tray 4 placed on the guide roller 3, and the roller way conveying device is matched with the mechanical arm to work, so that the automobile crankshaft of the type corresponding to the tray can be accurately placed on the tray, and the production automation level is high.

When the tray 4 is conveyed forwards, the tray 4 overcomes the elasticity of the torsion spring to push the thrust block 92 to swing, the bottom surface of the tray 4 presses the thrust block 92, the tray is conveyed forwards smoothly, after the tray 4 passes through the thrust mechanism 9, the torsion spring 95 pulls the thrust block 92 by the elasticity applied to the thrust block 9, the thrust block is pressed on the limiting groove 93, the thrust block 92 is in a vertical state at the moment, even if the tray 4 pushes the thrust block 92 backwards, the thrust block 92 can be limited and rotated by the support 91, so that the tray 4 is prevented from moving backwards, the tray 4 is guaranteed to move only in one direction, and the tray 4 entering the detection station is prevented from moving backwards and being separated from the roller way conveying device to cause the crankshaft to fall onto the ground.
In a preferred embodiment, as shown in fig. 1, guide strips 10 are arranged on the inner sides of the two mounting seats, the guide strips 10 extend along the conveying direction of the tray 4, and the guide strips 10 are fixedly connected with the mounting seats 2 through mounting plates 11. Tray 4 moves between two gibs 10, and gibs 10 guide tray 4 keeps rectilinear movement track, prevents that the tray off tracking from influencing the placement accuracy of bent axle.
In a preferred embodiment, as shown in fig. 9, the output end of the driving motor 61 is in transmission connection with a torque limiter, the torque limiter 62 is provided with a friction sprocket 63, the end of each guide roller 3 is provided with a driving sprocket 31 and a driven sprocket 32, the friction sprocket 63 is in transmission connection with the driving sprocket 31 of one of the guide rollers through a first chain 64 (only a part of the chain is shown in the figure), and the driven sprockets 32 of all the guide rollers 3 are in transmission connection with a second chain 65 (only a part of the chain is shown in the figure). The torque limiter comprises a coupling main body, a driving friction plate, a driven friction plate, a disc spring and a locking end cover, wherein the driving friction plate, the driven friction plate, the disc spring and the locking end cover are arranged on the coupling main body, the friction chain wheel 63 is arranged between the driving friction plate and the driven friction plate, and the disc spring is used for pressing the driven friction plate to enable the friction chain wheel 63 to rotate under the action of friction force provided by the driving friction plate and the driven friction plate. The compression amount of the disc spring can be adjusted by locking the end cover, so that the effect of adjusting the torsion preset value of the torsion limiter is achieved. When the external force received by the guide roller 3 exceeds 75N, the transmission torque of the friction sprocket 63 and the torque limiter 62 can be instantly increased and exceeds the preset sliding torque value of the torque limiter 62, so that the friction sprocket and the torque limiter slip, the guide roller 3 immediately stops moving, and the purpose of protecting the safety of manual operation is achieved.
In a preferred embodiment, as shown in fig. 2, each of the first bearing seat 45 and the second bearing seat 46 includes two positioning blocks 49.1 symmetrically arranged and two limiting lugs 49.2 arranged on the positioning blocks, and a trapezoidal notch 49.3 is formed at the top of each of the positioning blocks 49.1. The crank of the crankshaft is placed on the corresponding positioning block 49.1, the bottom surface of the trapezoid notch is a step surface and is composed of two planes with different heights, and each part of the crank is respectively pressed on the step surface to form positioning. In addition, the limiting lug 49.2 has a limiting effect on the crank and prevents the crank shaft from axially shaking. In addition, in order to facilitate the operator to judge the direction of the tray 4 by naked eyes, the front side of the tray is provided with an identification sheet 49.4; in order to facilitate the handling of the tray by the operator, two handles 49.5 are provided on the tray.
It should be understood that equivalents and modifications of the technical solution and inventive concept thereof may occur to those skilled in the art, and all such modifications and alterations should fall within the protective scope of the present invention.
