The present application is described in further detail below with reference to figures 1-3.

The embodiment of the application discloses a reinforced roller frame 12 for turnover welding.

Referring to fig. 1, a reinforced roller frame 12 for flip welding includes a base 11, the base 11 is fixed on the ground, and roller devices are installed at two ends of the top surface of the base 11. The roller device comprises roller frames 12, the roller frames 12 are installed on two sides of the top surface of the base 11, active rollers 13 are installed in the roller frames 12 on two sides, the number of the active rollers 13 in this embodiment is four, and four active rollers 13 are installed on the roller frames 12 two by two respectively. In addition, a motor 14 for driving the driving roller 13 to rotate is installed at one side of the roller frame 12 at both sides.

Referring to fig. 2, in order to reduce the vibration of the workpiece when the roller frame 12 rotates, a damping mechanism and an auxiliary damping mechanism are mounted on the base 11, wherein the auxiliary damping mechanism includes a protective sleeve, and the protective sleeve includes a column 32 and a cavity formed on the top surface of the column 32. Specifically, the number of the columns 32 is two in the present embodiment, two columns 32 are fixed at the middle position of the top surface of the base 11, and at the same time, the second spring 31 is fixed at the bottom of the cavity.

When the deformation amount of the second spring 31 is too large, the second spring 31 can be accommodated in the cavity of the cylinder 32, and the cylinder 32 replaces the second spring 31 to serve as a supporting piece, so that the second spring 31 is effectively protected, and the service life of the second spring 31 is prolonged.

The damping mechanism comprises a bottom plate 21, the bottom plate 21 is arranged on the top surfaces of two fixed second springs 31, meanwhile, the two ends of the top surface of the bottom plate 21 are symmetrically provided with fixed blocks 22, opposite side surfaces of the fixed blocks 22 at the two ends are symmetrically and horizontally provided with cavities, and a side wall far away from an opening of each cavity is fixedly provided with a first spring 23.

And a sliding rod 24 is slidably mounted on the inner walls of the cavities at the two sides, wherein the two ends of the sliding rod 24 are respectively fixed with one ends of the first springs 23 at the two sides, which are close to the openings of the cavities. A contact block 25 is arranged in the middle of the top surface of the sliding rod 24, and a groove 26 matched with the workpiece is formed in the top surface of the contact block 25 in order to increase the contact area between the contact block 25 and the workpiece. In addition, in order to increase the friction force between the groove 26 and the workpiece, a rubber pad 27 is laid on the top of the groove 26, and the rubber pad 27 and the workpiece are abutted against the rubber pad 27 under the action of a second spring 31.

When the workpiece vibrates in the horizontal direction, the workpiece drives the contact block 25 and the sliding rod 24 connected with the contact block 25 to vibrate in the horizontal direction through the rubber pad 27, and at the moment, the first springs 23 at the two ends of the sliding rod 24 play a role in buffering the sliding rod 24, so that the vibration of the workpiece in the horizontal direction is reduced.

Referring to fig. 3, for making things convenient for maintenance person to overhaul and maintain first spring 23, be provided with maintenance portion on fixed block 22, maintenance portion is including the maintenance mouth, and the maintenance mouth is seted up at the top surface of fixed block 22, and simultaneously, the inner wall department at the maintenance mouth articulates there is sunshade 41 with maintenance mouth looks adaptation, has the fender edge 43 of being fixed with to the side of sunshade 41 at the maintenance mouth is articulated, keeps off along 43 and is used for supporting sunshade 41, has effectively prevented that sunshade 41 from falling into the cavity. The side of the top surface of the shield plate 41, which is far away from the hinged part of the shield plate 41, is hinged with the pull ring 42, when the shield plate 41 needs to be pulled up, the pull ring 42 is rotated to a proper position, then the pull ring 42 is pulled by hands until the maintenance opening is completely exposed, when the shield plate 41 does not need to be pulled up, the pull ring 42 is rotated until the pull ring 42 is attached to the top surface of the shield plate 41, and therefore the influence of the pull ring 42 on a workpiece can be effectively reduced.

Further, the second spring 31 protrudes from the tip of the column 32 when the roller frame 12 is not loaded with a workpiece.

The implementation principle of the reinforced roller frame 12 for flip welding in the embodiment of the application is as follows:

when a workpiece is placed on the roller frame 12, the driving rollers 13 on both sides abut against the surface of the workpiece, and at the same time, the contact block 25 abuts against the surface of the workpiece by the second spring 31. The contact area between the workpiece and the contact block 25 is increased, and the condition that the workpiece slips between the roller frame 12 and the roller frame 12 when the roller frame 12 rotates is reduced. Meanwhile, the groove 26 and the rubber pad 27 on the top surface of the contact block 25 further improve the anti-skid effect of the contact block 25 on the workpiece.

When the deformation of the second spring 31 is too large due to the over-mass of the workpiece, the second spring 31 contracts into the cavity on the top surface of the column 32, and the column 32 acts as a bearing member to support the bottom plate 21, thereby protecting the second spring 31.

And then starting the motor 14, wherein the motor 14 drives the driving roller 13 to rotate so as to drive the workpiece to rotate, and the workpiece generates vibration in the rotation process of the workpiece, wherein when the workpiece generates vibration in the horizontal direction, the workpiece exerts a force in the horizontal direction on the specified block, at the moment, the fixed block 22 drives the sliding rod 24 to slide, and as the first springs 23 fixed with the two ends of the sliding rod 24 are arranged in the cavities at the two sides, when the sliding rod 24 slides, the first springs 23 play a role in buffering the sliding rod 24, so that the sliding distance of the sliding rod 24 is reduced, and the vibration between the workpiece and the roller frame 12 is reduced.

After the first spring 23 is used for a period of time, the first spring 23 needs to be repaired, at this time, the pull ring 42 is pulled up and the shutter 41 is opened until the maintenance opening is completely exposed, then the first spring 23 is repaired, after the repair is completed, the shutter 41 is reset, and the pull ring 42 is rotated to cling the pull ring 42 to the surface of the shutter 41.

The above are all preferred embodiments of the present application, and the present embodiment is only explained for the present application, and the protection scope of the present application is not limited by this, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
