It should be noted that, the first linear driving assembly 51 and the second linear driving assembly 52 may both use driving components for driving linear motion, such as a screw-nut device or a linear motor, and through the linear driving, the position of the welding gun 55 may be adjusted, so as to ensure that during welding, the output end of the welding gun 55 may achieve accurate welding.
In the above technical solution, as shown in fig. 9, the joints between the ends of the beam tube 1021 and the diagonal tube 1022 and the side of the head tube 101 are welding tracks, and because the beam tube 1021 is horizontally disposed, the diagonal tube 1022 is obliquely disposed, and the head tube 101, the beam tube 1021 and the diagonal tube 1022 are all tubes, the welding tracks at the joints are complex, and although the welding gun 55 can be driven to move along the welding tracks to perform welding operation by the programming of the mechanical arm, the welding gun is not suitable for small-sized engineering due to the high price and maintenance cost of the mechanical arm, therefore, the invention also provides a linear driving assembly three 53 and a guiding mechanism 6 for guiding the welding gun 55, so that the welding gun 55 can perform complex welding track movement without the programming operation of the mechanical arm, thereby greatly reducing the production cost.
Specifically, referring to fig. 6 to 8 of the specification, the welding mechanism 5 further includes a third linear driving assembly 53, the third linear driving assembly 53 includes a supporting seat 531, a fourth power component 532 is mounted on the supporting seat 531, a sliding seat 533 is mounted at an output end of the fourth power component 532, a guiding mechanism 6 is further disposed on the sliding seat 533, the guiding mechanism 6 is used for guiding the welding gun 55 to enable the welding gun 55 to move along a welding track, the guiding mechanism 6 includes a sliding block 61, the sliding block 61 slides laterally on the sliding seat 533, a top seat 62 is vertically sliding on the sliding block 61, a vertical shaft 63 is fixedly disposed at a bottom of the top seat 62, a ball 631 is mounted at a bottom end of the vertical shaft 63, a guiding seat 64 is mounted at a side edge of the supporting seat 531, a track groove 641 is formed in the guiding seat 64, and the ball 631 slides in the track groove 641.
It should be noted that, the fourth power component 532 may be a cylinder, in the process of driving the welding gun 55 to move linearly through the cylinder, the vertical shaft 63 is driven to move synchronously through the top seat 62, because the ball 631 at the end of the vertical shaft 63 is slidably disposed in the track groove 641, and the track groove 641 and the joints of the ends of the beam tube 1021 and the inclined tube 1022 and the side surface of the head tube 101 are the same, the ball 631 can be driven to move in the track groove 641, meanwhile, because the sliding block 61 is laterally slidably disposed on the sliding seat 533, the top seat 62 is vertically slidably disposed on the sliding block 61, and the welding gun 55 is fixedly disposed with the top seat 62, so that the welding gun 55 can move up and down and left and right under the joint of the sliding seat 533, the sliding block 61 and the top seat 62, and the ball 631 at the end of the vertical shaft 63 slides in the track groove 641, so that the welding gun 55 can be driven to move along the track of the track groove 641, thereby realizing the operation along the track movement of the joints of the ends of the beam tube 1021 and the inclined tube 1022 and the side surface of the head tube 101.
Further, referring to fig. 6 of the present disclosure, the welding mechanism 5 further includes a fourth linear driving assembly 54, the fourth linear driving assembly 54 includes a support plate 541, the fifth power component 542 is fixedly mounted on the table 1, an output end of the fifth power component 542 is fixedly connected to the support plate 541, and the first linear driving assembly 51 is mounted on the support plate 541.
It should be noted that the number of the track grooves 641 is two, and the two track grooves 641 are mirror images, after the welding of the joints of the ends of the beam tube 1021 and the chute 1022 and the side face up of the head tube 101 is completed, the beam tube 1021, the chute 1022 and the head tube 101 are turned over again, after the turning over is completed, the welding gun 55 is driven to retract to the initial position by the driving of the supporting plate 541 by the cylinder, then the welding gun 55 is driven to move by the driving of the third linear driving component 53 and the guiding mechanism 6, and the welding treatment is performed on the joint of the other part.
In the above technical solution, although the distance between the beam tube 1021 and the end of the chute 1022 is relatively short, but there is still a certain distance, so during the movement of the welding gun 55 in this distance, in order to avoid the damage of the welding gun 55 to the side of the head tube 101, this problem may be avoided by closing the welding gun 55 and restarting the welding gun 55 during the movement in this distance, but the repeated switching may cause the welding area to undergo thermal cycling many times, resulting in the change of microstructure in the heat affected zone, so that the problem of deformation of the side of the head tube 101 may be solved, so that the welding gun 55 may be moved away from the head tube 101 by moving the beam tube 1021, the chute 1022 and the head tube 101, or by moving the welding gun 55 in this distance, but if the beam tube 1021, the chute 1022 and the head tube 101 are moved, this series of operations need to be driven by driving components, and at the same time, it is also ensured that the driving components are not easy to move along with these operations, and the movement of the beam tube 1021, the chute 1022 and the head tube 101 are moved away from the head tube 101 by the distance 55.
Specifically, referring to fig. 8 of the specification, the guide holder 64 is further provided with a guide groove 642, the guide groove 642 is in communication with the track groove 641, and the guide groove 642 is located in the middle of the track groove 641.
It should be noted that, by providing the guide groove 642 communicating with the track groove 641 on the guide holder 64, when the welding gun 55 moves along the track groove 641, the welding gun 55 can be far away from the head pipe 101 in the moving process of the distance through the guide groove 642, so as to avoid the damage of the welding gun 55 to the side surface of the head pipe 101.
Referring to fig. 10 of the drawings, a welding process of a bicycle machining welding device comprises the following steps:
Step one, fixing the head pipe 101, the cross beam pipe 1021 and the inclined pipe 1022 through the head pipe fixing assembly 21 and the side pipe fixing assembly 22, and attaching the end parts of the cross beam pipe 1021 and the inclined pipe 1022 to the side surface of the head pipe 101;
step two, the pressing mechanism 4 applies pressure to the transverse beam 1021 and the inclined tube 1022 through the pressing plate 42, so that the joint of the transverse beam 1021 and the inclined tube 1022 and the head tube 101 is always kept in a tightly-attached state;
Step three, the welding mechanism 5 drives the welding gun 55 to weld the flat transverse beam 1021 and the inclined tube 1022 with the upper welding seam of the head tube 101, and after the welding is finished, the turnover mechanism 3 drives the transverse beam 1021 and the inclined tube 1022 as well as the head tube 101 to turn over;
and fourthly, finally, the welding mechanism 5 drives the welding gun 55 to weld the beam tube 1021 and the inclined tube 1022 with the upward lower welding seam after the head tube 101 is turned over.
The foregoing examples illustrate only a few embodiments of the invention and are described in detail herein without thereby limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention.
