Description

Technical Field

[0001] The utility model belongs to the technical field of automatic robot accessories, and in particular relates to a fixed frame of a handheld tightening gun. Background Art

[0002] Industrial robots are multi-joint manipulators or multi-degree-of-freedom machine devices widely used in the industrial field. They have a certain degree of automation and can achieve various industrial processing and manufacturing functions by relying on their own power and control capabilities. Especially in the field of automotive parts, industrial robots have made an indispensable contribution to the transformation of labor-intensive assembly lines into automated production lines.

[0003] Since screws need to be tightened on each assembly production line, a tightening gun is needed in the automated production line. The structure of the original handheld tightening gun is only suitable for manual operation and is not suitable for installation on an industrial robot. Therefore, the original handheld tightening gun cannot be directly used on the automated production line. In addition, the handheld tightening gun is expensive, and abandoning the handheld tightening gun is likely to cause a waste of resources. Utility Model Content

[0007] In the above scheme, the handheld tightening gun is fixed on the mounting base plate, and the mounting base plate has a first fixing part and a second fixing part. The middle part and the front part of the handheld tightening gun are fixed to the mounting base plate by the first fixing part and the second fixing part respectively, and the handheld tightening gun is connected to the industrial robot through the connecting plate above the first fixing part, so that the handheld tightening gun is fixed to the industrial robot.

A first connecting flange edge 23 is provided on the outer side of the connection between the first lower half 21 and the first upper half 22. The first connecting flange edge 23 is tightened by bolts so that the first lower half 21 and the first upper half 22 are enclosed and fixed at the middle part of the hand-held tightening gun A.

[0014] Furthermore, the connecting plate 40 is an L-shaped folded plate constructed by a horizontal plate 41 and a vertical plate 42. The connecting plate 40 is fixedly connected to the upper flange 221 on the upper part of the first upper body 22 through the horizontal plate 41, and then fixedly connected to the industrial robot through the vertical plate 42, thereby realizing a fixed connection between the handheld tightening gun A and the industrial robot.

[0015] Preferably, in order to further fix the head of the hand-held tightening gun A and prevent the head of the hand-held tightening gun A from shaking, the second fixing part 30 includes a second lower half 31 fixedly connected to the mounting base plate 10 and a second upper half 32 which encloses a tubular cavity area with the second lower half 31 to constrain and fix the middle part of the hand-held tightening gun A. A second connecting flange edge 33 is provided on the outer side of the connection between the second lower half 31 and the second upper half 32. The second connecting flange edge 33 is tightened by bolts so that the second lower half 31 and the second upper half 32 are enclosed and fixed in the middle part of the hand-held tightening gun A.

[0016] Preferably, a first lower flange 211 is provided below the first lower half 21, and part of the first lower flange 211 is embedded in the body of the mounting substrate 10 and is connected to the flange of the mounting substrate 10; a second lower flange 311 is provided below the second lower half 31, and part of the second lower flange 311 is embedded in the body of the mounting substrate 10 and is connected to the flange of the mounting substrate 10, thereby ensuring the connection stability of the first lower half 21, the second lower half 31 and the mounting substrate 10 in the up and down directions and the circumferential directions.

[0017] Furthermore, the floating tightening device 50 includes a mounting plate 52 that is fixedly attached to the lower plate of the mounting base plate 10 and a connecting shaft 51 that penetrates the mounting base plate 10 from bottom to top and is transmission-connected to the output end A1 of the hand-held tightening gun A.
