Detailed Description

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 and fig. 2, an embodiment of the present invention provides a large pipe fitting assembling apparatus, which includes an assembling mechanism, a turnover mechanism, and a moving and feeding mechanism. The turnover mechanisms are arranged in multiple groups, and each group of turnover mechanisms is provided with two turnover mechanisms which are spaced at a certain distance to support two ends of the large pipe fitting 1. The turnover mechanism comprises a supporting base 2, two longitudinal roller frames 3 arranged on the supporting base 2, and a longitudinal roller 4 rotatably arranged on each longitudinal roller frame 3. In this embodiment, the distance between two vertical roller frames 3 disposed on each supporting base 2 is preset, so that the pipe 1 can be placed between the upper surfaces of two vertical rollers 4, and the pipe 1 and the tangent lines of the two vertical rollers 4 form an included angle of 120 degrees. Meanwhile, one of the longitudinal rollers 4 is driven by a turnover driving motor arranged in the longitudinal roller frame 3 to rotate longitudinally around the transverse shaft to serve as a driving wheel, and the other longitudinal roller 4 freely rotates longitudinally around the transverse shaft to serve as a driven wheel. When the active longitudinal roller 4 rotates, the pipe fitting 1 is heavy, so that the surface of the pipe fitting 1 and the surface of the longitudinal roller 4 are in static friction contact, relative sliding cannot be generated, the pipe fitting 1 can turn over along with the rotation of the longitudinal roller 4, and the assembling mechanism can conveniently process and assemble the surface positions of the pipe fitting 1.

The movable feeding mechanism comprises two feeding guide rails 5, a bridge 6 movably arranged on the feeding guide rails 5, a bearing frame 7 arranged on the bridge 6, a transverse roller frame 8 arranged on the bearing frame 7, and a transverse roller 9 rotatably arranged on the transverse roller frame 8. The feeding guide rails 5 are arranged in parallel with the turnover mechanisms arranged in the same row along the longitudinal direction, the bridge frame 6 is erected between the two feeding guide rails 5, the bottom parts of the two ends are respectively provided with a bearing wheel 10 in a rotating mode, and the bearing wheels 10 are arranged on the corresponding feeding guide rails 5 in a rolling mode, so that the bridge frame 6 can move along the longitudinal direction of the feeding guide rails 5.

The bearing frame 7 is further provided with a jacking driving part, specifically is a jacking cylinder 11, the jacking cylinder 11 is vertically arranged, the end part of a piston rod is fixedly connected with the transverse roller frame 8, and the lifting action of the transverse roller frame 8 is controlled through the expansion and contraction of the piston rod. The transverse roller 9 is arranged in a dumbbell shape, is arranged along the longitudinal direction and rotates around the longitudinal axis along the transverse direction under the driving of a transverse moving driving motor.

In this embodiment, the position of each group of turning mechanisms is a processing station, the pipe fitting 1 at the processing station is placed on the longitudinal roller 4, and the pipe fitting 1 is turned by the rotation of the longitudinal roller 4, so that the assembling mechanism can complete one type of processing on the surface of each part of the pipe fitting 1. After the pipe fitting 1 needs to move to the next station for another type of processing, the jacking cylinder 11 drives the transverse roller frame 8 to lift, so that the transverse roller 9 is gradually contacted with the pipe fitting 1 to form support. Because the transverse roller 9 is dumbbell-shaped, the pipe fitting 1 is positioned in the middle of the transverse roller 9 when being supported by the transverse roller 9, and the protruding parts at the two ends limit the transverse roller 9 to prevent the pipe fitting from rolling out of the transverse roller 9, so that the pipe fitting 1 is stably supported by the dumbbell-shaped transverse roller 9. With further lifting of the transverse roller frame 8 and the transverse rollers 9, the weight of the pipe 1 is loaded on the transverse rollers 9 in its entirety and is no longer supported by the longitudinal rollers 4. At this time, the traverse roller 9 may be rotated to adjust the lateral distance of the pipe 1 to change the distance between the next processing position of the pipe 1 and the assembling mechanism.

In the process of moving the pipe fitting 1 to the next station, the bridge 6 is driven by the material moving driving part to move to the next station along the feeding guide rail 5, the transverse roller 9 drives the pipe fitting 1 to longitudinally move, and two sides of the dumbbell-shaped protrusion can further ensure that the pipe fitting 1 cannot roll out. After the transverse roller 9 drives the pipe fitting 1 to move to the next station, the jacking cylinder 11 drives the transverse roller frame 8 to descend, the pipe fitting 1 is placed on the longitudinal roller 4 at the next station, the transverse roller frame 8 further descends to enable the transverse roller 9 to not support the pipe fitting 1 any more, the weight of the pipe fitting 1 is completely loaded on the longitudinal roller 4, and the pipe fitting 1 can be processed at the moment and overturned through the rotary driving of the longitudinal roller 4.

As a preferred embodiment, in this embodiment, the bridges 6 are disposed in one-to-one correspondence with each group of turning mechanisms, and all the bridges 6 are fixed by the connecting frame 12 to form an integral structure, and are driven by the material moving driving portion to move in a unified manner. Therefore, after the pipe fittings 1 at the first station and the second station are completely processed in the first type and the second type respectively, the bridge frame 6 integrally moves the two pipe fittings 1 to the second station and the third station respectively through one-time displacement to perform the second type processing and the third type processing, so that all the pipe fittings 1 on the processing line can be moved by one-time displacement of the bridge frame 6, and the processing efficiency of the pipe fittings 1 is improved. Based on the maximization and the heaviness of the pipe fitting 1, the pipe fitting is connected into an integral structure through the connecting frame 12, the integral strength can be improved, and the stability of material moving and the reliability of equipment operation are ensured.

Wherein, the assembly devices are a plurality of assembly robots 13 which are respectively arranged at two sides of the feeding guide rail 5, correspond to each station and can carry out full-automatic processing of corresponding types on the pipe fittings 1.

While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the appended claims.
