Description

one

The invention relates to welding, in particular to the construction of a production line for assembling for welding of bodies of mine trolleys.

The known assembly line for assembling for welding of bodies of mine trolleys, comprising a section for assembling and welding of trolleys, a tilter located between these sections, and lifting and transporting vehicles ij ..

The disadvantage of this production line is that it is inefficient, since the auxiliary time is long.

The purpose of the invention is to increase productivity by reducing the auxiliary time.

This is achieved by offering; The production line is equipped with an additional tilter and a rotatable table in the horizontal plane, with both tilters mounted on the table parallel to one another, and the longitudinal axis of the assembly and sidewall welding section is offset relative to the longitudinal axis of the assembly and welding of trolleys.

Figure 1 shows the described flow line, top view; in fig 2

view A of figure 1; on fig.Z - section bb of figure 1; figure 4 is a section bb In figure 1.

The continuous line is sotoit from section 1 of the sidewall assembly, turntable 2 and section 3 of the body assembly.

Section I includes stand 4 of the sidewall assembly, stands 5 and 6 of welding, and step conveyor 7.

On the turntable 2, offset from the side assembly section 1 and the body assembly 3 aligned with section 3, are installed the contactors 8 and 9. The rotary table 2 adjoins the drive 10 with the stacker 11.

Section 3 of the body assembly consists of the body assembly stand 12, the installation stand 13, and the transport device 14 with grippers 15 and 16. Next to the body assembly stand 12, a cassette 17 with lobovings is installed. 18 and a cantilever crane 19.

Flow line works as follows.

25, orientation, clamping and clamping of the sidewall and square are passed on stand 4 of the sidewall assembly; on stand 5 and 6 of welding — orientation, clamping, turning to the welding position and

30, the automatic welding of the sidewall 20. Upon completion of the work on the stands of section 1, the products are released and the stepping conveyor 7 is passed forward to the step. from the last stand 6 welding sidewall; 20 is supplied by the stepping conveyor 7 to the turning device 8, which is in a horizontal position. Kahn; commodity 8 (FIG. 3) places the sidewall 20 in a vertical position with a square 21 to the axis of the turntable 2. The rotary table 2 coaxially with the subsequent section 3 of the overall assembly is shifted relative to the previous section 1, so that after turning the sidewall 20 becomes from the axis of the table 2 at a distance greater than half the width of the front part 18 by the size of the setting gap B, the Table 2 turns 180 °, sidewall, 20 is in the left position, the second tilter 9 is lowered to the horizontal position. After the end of the next cycle, the second sidewall is placed in the same vertical position on the right. Table 2, in addition to orienting the sidewalls 20, before serving the assembly, serves as a matching link: on it, two sidewalls 20 are prepared in time. assemblies of one body, since the rhythm of section 3 of the assembly of the body, equal to the beat of the exit of the product, is twice the pain Bse of the rhythm of section 1. of the sidewall assembly. At the body assembly section, orientation, clamping and tacking of sidewalls 20 and lobovin 18 are made at the first stand 12, and installation and welding at the corners of the next wall de 13 is made at the corners of the body of the link. After completing the work on the stands of Section 3 of the body assembly, the grips: 15 and 16 of the transport device 14 lower, grip the products, lift them, move them one step further, lower them onto the next stands and rise upwards. The first gripper 15 lowers the sides 20 after the cantilever 19 collects the loboviny 18 from the cassette 17 to stand 12. When the first gripper 15 rises, it returns to its original position along with the remaining 16. In addition to the described operating mode, the line can operate in the mode of accumulation or sampling of the sidewalls. If the body assembly section 3 of the sidewall 20 stops from the table of the rotary 2, the stacker 11 is fed to the accumulator 10. In case of the assembly of the side panel assembly 1, the sidewall 20 of the accumulator 10 is fed to the TURNING table 2 and further as previously described to the body assembly stand 12. Application displaced relative to the previous one and coaxially with the subsequent section of the rotary table equipped with tilting table allows to significantly simplify the transfer of the bulky basement of the sidewall body, orient it during the transfer and coordinate the work of two x sections of the line working with different rhythms, which significantly increases productivity. Formula of the Invention Line for assembly for welding a body of mine trolleys comprising a side assembly portion, a portion of assembly and welding trolleys, a tilter disposed between these portions, and elevators, characterized in that, in order to increase productivity by reducing the auxiliary time, the flow line is equipped with an additional 1/5 tilter and a rotary table in the horizontal plane, with both tilting devices mounted I on the table parallel to one another, and longitudinally about s portion of the assembly and welding of the sidewalls is offset relative to the longitudinal axis of the assembly portion and welding trolleys.
