Description

Technical Field

[0001] The utility model relates to the technical field of tool processing, in particular to a double-station composite tool blank welding device. Background Art

[0002] A composite blade blank refers to the initial form of a blade body formed by combining two or more different materials through a specific process during the manufacturing process of the blade. This design aims to combine the advantages of different materials to meet the requirements of hardness, toughness, wear resistance, corrosion resistance and other performance requirements during the use of the blade. For example, the blade back is usually made of stainless steel to meet the hardness requirements of the overall tool, and the blade is usually made of wear-resistant high-carbon steel to provide good edge retention. Therefore, the two materials of the blade blank need to be welded before grinding the tool. In the welding process of traditional composite blade blanks, there is usually only one station for the welding gun to operate. After welding is completed, the welded blade blank needs to be removed and replaced with a new blade blank to be welded, and then welding is continued. Therefore, the welding efficiency is low and cannot meet production needs. To this end, we proposed a dual-station composite blade blank welding device. Utility Model Content

[0020] In order to solve the problem of low efficiency of blade welding in the prior art and the inability to realize the parallel operation of welding and loading and unloading, the following technical solution is given. Please refer to Figure 1-4 ;

[0021] A double-station composite blade blank welding device includes a base plate 1, a rotary cylinder 2 is provided in the middle of the base plate 1, a first rotating shaft 3 is installed on the rotating disk of the rotary cylinder 2, the top of the first rotating shaft 3 is connected to the middle of the first rotating bracket 4, first vertical rods 5 are provided at both ends of the first rotating bracket 4, and processing platforms 6 are provided on the top of the first vertical rods 5. The center of the processing platform 6 is connected to the first vertical rod 5 through a bearing, and the same side of the two processing platforms 6 is connected to the parallel rotating assembly, and a blade blank clamping device is also provided on the processing platform 6. A mechanical arm 11 is provided on the side of the base plate 1 away from the support 7, and the mechanical arm 11 is arranged opposite to the support 7. A welding gun 12 is provided at the bottom of the mechanical arm 11, and the welding gun 12 faces the position near the middle of the processing platform 6. The rotating cylinder 2 drives the first rotating shaft 3 to rotate, the first rotating shaft 3 drives the first rotating bracket 4 to rotate, the first rotating bracket 4 drives the two processing platforms 6 to rotate through the first vertical rod 5, and the turntable of the rotating cylinder 2 rotates 180° each time, so that the two processing platforms 6 rotate in turn to the bottom of the welding gun 12 to weld the knife blank.

[0022] The parallel rotating assembly includes a support 7, a second rotating shaft 8, a second rotating bracket 9 and a second vertical rod 10. The support 7 is arranged on one side of the base plate 1. The top of the support 7 is provided with a second rotating shaft 8. The bottom end of the second rotating shaft 8 is connected to the middle part of the second rotating bracket 9. The two ends of the second rotating bracket 9 are respectively rotatably connected to the same side of the two processing platforms 6 through the second vertical rod 10. The first rotating bracket 4 and the second rotating bracket 9 have the same length, the distances from the two first vertical rods 5 to the first rotating shaft 3 are equal, the distances from the two second vertical rods 10 to the second rotating shaft 8 are equal, and the straight lines formed by the connection points of the first vertical rods 5 and the second vertical rods 10 on the two processing platforms 6 are parallel; when the processing platform 6 rotates, the second vertical rod 10 will drive the second rotating bracket 9 to rotate around the second rotating shaft 8, and the second rotating bracket 9, the first rotating bracket 4 and the two processing platforms 6 form a parallelogram structure. When the second rotating bracket 9 and the first rotating bracket 4 rotate by a certain angle, the two processing platforms 6 can always be parallel to each other, so that when each processing platform 6 rotates to the bottom of the welding gun 12, the blade blank welding point above it can be kept in a fixed position, thereby facilitating the welding operation of the welding gun 12 on it.

[0023] Two sets of blade clamping devices are symmetrically arranged on each processing platform 6, and the blade clamping devices include a connecting plate 13, a first fixed plate 14, a second fixed plate 15, a movable plate 16, a stud 17 and a knob 18.

The first fixed plate 14 and the second fixed plate 15 are rotatably connected with the stud 17, and the movable plate 16 is threadedly engaged with the stud 17. The top of the stud 17 is also provided with a knob 18. Two blades are respectively placed in a set of blade clamping devices, and the blade is placed on the second fixed plate 15. The knob 18 is turned, and the stud 17 drives the movable plate 16 to move toward the second fixed plate 15 through threaded engagement until the movable plate 16 presses against the upper surface of the blade, so that the movable plate 16 cooperates with the second fixed plate 15 to clamp the blade, which is convenient for subsequent welding operations.

[0024] A third vertical rod 19 is respectively provided at both ends of the bottom surface of the first rotating bracket 4, and a universal wheel 20 is provided at the bottom end of the third vertical rod 19. The universal wheel 20 is in contact with the surface of the bottom plate 1. The third vertical rod 19 effectively supports both sides of the first rotating bracket 4, thereby maintaining the balance of the first rotating bracket 4 and avoiding deflection during use; the provision of the universal wheel 20 can reduce the friction force generated by the third vertical rod 19 and the bottom plate 1 when moving, so that the rotation process of the first rotating bracket 4 is smoother.

[0025] Working principle: Place the knife blank on the second fixed plate 15, turn the knob 18, and make the stud 17 drive the movable plate 16 to move toward the second fixed plate 15 through threaded cooperation, so that the movable plate 16 cooperates with the second fixed plate 15 to clamp the knife blank, and the turntable of the rotating cylinder 2 rotates 180° each time, and drives the two processing platforms 6 to rotate through the first rotating shaft 3, the first rotating bracket 4 and the first vertical rod 5 in turn, so that the processing platforms 6 rotate in turn to the bottom of the welding gun 12 to weld the knife blank.
