Description

Technical Field

[0001] The utility model relates to the technical field of a welding machine for a truck weighing platform, in particular to a walking welding machine for a truck weighing platform. Background Art

[0002] The truck scale is a large weighing device used to weigh cars. When assembling some parts of the truck scale, welding is usually used to fix them. Due to the long length of the truck scale and in order to save manpower, a walking welding machine is usually used to move along the length of the truck scale for welding. The walking welding machine can move along the corresponding track and stop when it reaches the welding position before welding.

[0003] The walking welding machines on the market are generally equipped with tracks at the bottom, and the rotation of the lead screw is used to drive the welding machine to move. However, when this type of lead screw-driven walking welding machine is in use, the weight is borne on the lead screw, and the outer diameter of the lead screw is relatively small. It is easy to break after being subjected to a large gravity. Some walking welding machines are driven by racks and gears to move. A lot of weight is also accumulated on the rack, which is also easy to cause the rack to break under force, affecting the stability and firmness of the overall structure and causing inconvenience to the user. In view of this, we proposed a walking welding machine with a truck scale platform. Utility Model Content

The support frame assembly 2 includes a vertical slide rail 20 arranged in a vertical shape, and the welding mechanical arm 3 is arranged on the vertical slide rail 20. A base 21 is fixedly installed at the bottom end of the vertical slide rail 20. A driving motor 22 is fixedly installed on the front and rear side plates of the base 21. A gear 23 is fixedly installed at the end of the output shaft of the driving motor 22. The gear 23 and the rack 1 are meshed with each other, so that the driving motor 22 can be used to work and drive the gear 23 to rotate. Since the gear 23 and the rack 1 are meshed with each other, the base 21 can be driven to move;

[0027] Specifically, two symmetrical first rollers 25 are fixedly installed on the bottom surfaces of the front and rear side plates of the base 21, and load-bearing plates 27 are fixedly installed on the left and right side plates of the base 21. Side support rods 26 are fixedly installed between the load-bearing plates 27 and the vertical slide rails 20. A pillar 271 is fixedly installed on the bottom surface of the load-bearing plates 27, and a second roller 272 is fixedly installed on the bottom end of the pillar 271. The bottom ends of the first roller 25 and the second roller 272 are jointly supported on the ground for stable supporting operations, and the side support rods 26 can perform further compression-resistant supporting operations on the vertical slide rails 20.

[0028] In this embodiment, the side support rods 26, the load-bearing plates 27 and the vertical slide rails 20 form a triangle, which has stability, and the side support rods 26 are used for compression-resistant support operations.

[0029] Specifically, vertically arranged support legs 10 are fixedly installed on the bottom surfaces of the rod bodies at both ends of the rack 1, and a fixed base plate 11 is fixedly installed on the bottom ends of the support legs 10, so that the fixed base plate 11 can be fixed with fastening bolts to achieve the effect of fixing the rack 1.

[0030] Furthermore, a slide groove 12 is provided on the side of the rack 1 along the length direction of the rack 1, and a slide plate 24 is fixedly installed on the inner side surfaces of the front and rear side plates of the base 21. The slide plate 24 is located in the slide groove 12 and is slidably connected to the slide groove 12, so that the base 21 is more stable and smooth when moving.

[0031] In addition, a servo motor 28 is fixedly installed on the top surface of the vertical slide rail 20, and a vertically arranged screw rod 281 is fixedly installed on the end of the output shaft of the servo motor 28.
