Abstract
Description
Technical Field
[0001] The utility model belongs to the field of plate rolling, and in particular relates to a plate rolling handheld welding device. Background Art
[0002] After the rolled plate is bent into shape by the plate rolling machine, there is still a certain gap on its circular ring. At this time, the gap needs to be welded. However, the welding process requires the use of objects to fix the rolled plate and squeeze the rolled plate inward to minimize the gap of the rolled plate. In order to facilitate subsequent welding, it is more complicated to use objects to press down, and the objects are also easy to scratch the rolled plate. Utility Model Content
[0003] The utility model aims at the deficiencies of the prior art and provides a hand-held plate rolling welding device.
[0004] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a plate rolling handheld welding device, comprising a fixed body and a plate rolling with a gap, a guard plate is fixed at the bottom of the fixed body, and the feature is that a pressing assembly is installed at the bottom of the guard plate;
[0005] The pressing assembly includes a vertical plate fixed at the center of the guard plate, a bottom plate is installed on the side of the vertical plate away from the guard plate, a clamping plate is mounted on the vertical plate, and the clamping plate is connected to the bottom plate via a plurality of springs.
[0006] Optionally, the guard plate is arranged in an arc shape, and its arc radius is larger than the radius of the rolling plate, and a plurality of rolling balls are arranged on one end surface of the guard plate close to the rolling plate.
[0007] Optionally, the rolling balls are spherical and roll in the guard plate, and the rolling balls are equally divided into two groups, and the two groups of rolling balls are symmetrically arranged with the vertical plate as the center.
[0008] Optionally, a welding gun is obliquely mounted on the fixed body, and a handle is fixed to an end surface of the fixed body on one side away from the guard plate.
[0009] Optionally, the clamping plate extends to a side away from the vertical plate, and a plurality of friction rods are fixed to an end face of the clamping plate away from the bottom plate. The friction rods are all installed at an angle and are divided into two groups, which are symmetrically arranged with the vertical plate as the center.
[0010] In summary, compared with the prior art, the present invention has the following beneficial effects:
[0011] 1. Due to the setting of the pressing assembly, the guard plate can be set to press down the entire device. At this time, the guiding effect of the guard plate will cause the rolled plate to move toward the direction close to the vertical plate, thereby reducing the gap of the rolled plate, thereby facilitating the subsequent welding process.
[0012] 2. The obliquely installed friction rods also limit the rolls on both sides to move toward the side close to the vertical plate, so that the two sides of the rolls are further closed inward, further reducing the difficulty of welding. The rolls can also be protected by the bottom plate on the guard plate to prevent them from being scratched. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.
[0018] As shown in Figures 1-3, a plate rolling handheld welding device comprises a fixed body 10 and a plate rolling 11 with a gap, a guard plate 13 is fixed to the bottom of the fixed body 10, a welding gun 14 is obliquely mounted on the fixed body 10, and a handle 12 is fixed to the end face of one side of the fixed body 10 away from the guard plate 13.
[0019] A pressing assembly is installed at the bottom of the guard plate 13, which includes a vertical plate 15 fixed at the center of the guard plate 13, a bottom plate 16 is installed on the side of the vertical plate 15 away from the guard plate 13, a clamping plate 17 is mounted on the vertical plate 15, and the clamping plate 17 and the bottom plate 16 are connected by a plurality of springs.
[0020] The guard plate 13 is arranged in an arc shape, and its arc radius is larger than the radius of the rolling plate 11. A plurality of rolling balls 18 are arranged on the end face of one side of the guard plate 13 close to the rolling plate 11. The rolling balls 18 are arranged in a spherical shape and roll in the guard plate 13. The rolling balls 18 are divided into two groups, and the two groups of rolling balls 18 are symmetrically arranged with the vertical plate 15 as the center.
[0021] The clamping plate 17 extends to the side away from the vertical plate 15, and a plurality of friction rods 19 are fixed to the end face of the clamping plate 17 away from the bottom plate 16. The friction rods 19 are all installed at an angle, and the friction rods 19 are divided into two groups. The two groups of friction rods 19 are symmetrically arranged with the vertical plate 15 as the center. Through the arrangement of the friction rods 19, when the device is pulled backward, the friction rods 19 will generate two component forces on the rolling plate, one of which is parallel to the rolling plate gap, and the other is in the direction close to the vertical plate 15 and perpendicular to the vertical plate 15.
[0022] When in use, after the rolled plate is formed, the vertical plate 15 needs to be placed in the gap of the rolled plate. Then, the clamping plate 17 squeezes the inside of the rolled plate under the push of the spring, and then the entire device is pressed down with force. At this time, the guiding effect of the guard plate 13 will cause the rolled plate to move toward the direction close to the vertical plate 15, thereby narrowing the gap of the rolled plate, thereby facilitating the subsequent welding process. When opening welding, the device is pulled back by the handle 12. At this time, under the restriction of the obliquely installed friction rod 19, the rolled plates on both sides tend to move toward the side close to the vertical plate 15, so that the two sides of the rolled plate are further closed inward, further reducing the difficulty of welding.
[0023] Obviously, the described embodiments are only a part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
