DETAILED DESCRIPTION
[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.
[0030] Embodiment 1
[0031] Reference Figure 1-Figure 8 As shown, the utility model is an anti-torque arm for an electric torque wrench, comprising:
[0032] Power-assisted robotic arm 1;
[0033] The mounting base 2 includes a base plate 21 and an adjustment plate 22. The base plate 21 is connected to the output end of the power-assisting mechanical arm 1. Two connecting plates 23 parallel to each other are symmetrically arranged at one end of the base plate 21. A mounting shaft 24 is vertically connected between the two connecting plates 23. At least one adjustment plate 22 parallel to the connecting plate 23 is rotatably arranged on the mounting shaft 24. A plurality of adjustment holes 221 with the axis of the mounting shaft 24 as the center of the arc array are vertically opened on the adjustment plate 22. A through hole 231 corresponding to the arrangement path of the adjustment holes 221 is vertically opened on the connecting plate 23. A pin 25 for simultaneously passing through the through hole 231 and any one of the adjustment holes 221 is inserted in the through hole 231. A mounting plate 26 is also arranged on the adjustment plate 22, and a fixing hole 261 is opened on the mounting plate 26.
[0034] Specifically, the power-assisted robotic arm 1 can assist the operator to move the mounting base 2 and the wrench fixed thereon to any operating position without the operator having to hold the wrench, thereby reducing the operator's labor intensity; and by adjusting the adjustment plate 22, the angle of the mounting plate 26 and the wrench thereon can be adjusted, making it convenient for the staff to tighten fasteners at different angles on the product.
[0035] Specifically, by rotating the adjustment plate 22, the through hole 231 on the connecting plate 23 can be made to correspond to the different adjustment holes 221 thereon, and then the pin 25 can be simultaneously passed through the through hole 231 and the adjustment hole 221 at the corresponding positions to lock the angle of the adjustment plate 22, thereby realizing the adjustment of the angle of the mounting plate 26 connected to the adjustment plate 22 and the electric wrench thereon, which is simple and convenient to operate.
[0036] Reference Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, further, a support plate is arranged in parallel on the mounting plate 26, and two handles 27 are symmetrically mounted on the support plate and are respectively located on both sides of the fixing hole 261, and the handles 27 extend along the length direction of the support plate.
[0037] Furthermore, the handle 27 is a metal round rod, and a rubber sleeve is provided on the handle 27. The rubber sleeve can play an anti-slip role, which is helpful for the staff to hold the handle 27 stably.
[0038] Furthermore, a nut 232 coaxial with the through hole 231 is connected to any connecting plate 23, and the plug 25 includes a screwing section for screwing with the nut 232, and a plug-in section and a gripping section respectively connected to both ends of the screwing section, the plug-in section is coaxial with the screwing section, and the gripping section is perpendicular to the screwing section. Specifically, when the plug 25 is plugged in, the screwing section is screwed with the nut, and the screwing section screwed with the nut can connect the entire plug 25 with the connecting plate 23, so that the plug 25 is not easy to come out of the through hole 231 and the adjustment hole 221 after being vibrated or subjected to external force, which is conducive to safe production. Specifically, the gripping section is set to be flat and easy to be pinched by fingers, and is provided with anti-slip textures to facilitate operation by operators.
[0039] Furthermore, multiple adjustment plates 22 can be set at the same time, and each adjustment plate is provided with a connecting hole that is concentric with the center of the array arc of its adjustment hole 221. The multiple adjustment plates are connected to a sleeve through their respective connecting holes and are rotatably connected to the mounting shaft 24 through the sleeve. The multiple adjustment plates are connected to the mounting plate 26 at the same time.
[0040] Furthermore, the diameter of the plug-in section matches the inner diameter of the adjustment hole 221. Specifically, the plug-in section is a round rod that matches the inner diameter of the adjustment hole 221, and the diameter of the plug-in section should be slightly smaller than the inner diameter of the adjustment hole 221, so that the plug-in section can be smoothly inserted into the target adjustment hole 221, and at the same time, the shaking of the adjustment hole 221 caused by the excessive gap between the plug-in section and the adjustment hole 221 can be avoided, and the stability of the mounting plate 26 connected to the adjustment hole 221 and the torque wrench thereon can be ensured, which is convenient for the staff to operate.
[0041] Furthermore, the fixing hole 261 corresponds to the shape of the flower-shaped nut at the gun head end of the electric torque wrench, and the electric torque wrench can be stably inserted into the fixing hole 261 and will not rotate during operation.
[0042] Reference Figure 2 and Figure 3As shown, further, the power-assisting mechanical arm 1 includes a base column 11, one end of the base column 11 is rotatably connected to a main rotating arm 12 coaxial therewith, one end of the main rotating arm 12 away from the base column 11 is vertically provided with a connecting arm 13, the free end of the connecting arm 13 is rotatably connected to a first rotating seat 14, a lifting arm 15 is connected to the first rotating seat 14, the free end of the lifting arm 15 is rotatably connected to a second rotating seat 16, the second rotating seat 16 is rotatably connected to an auxiliary rotating arm 17, and the free end of the auxiliary rotating arm 17 is connected to a base plate 21. Specifically, the connecting arm 13 can rotate in the horizontal direction relative to the base column 11 through the main rotating arm 12, the lifting arm 15 can rotate in the horizontal direction relative to the connecting arm 13; the auxiliary rotating arm 17 can rotate by itself; the power-assisting mechanical arm 1 can provide auxiliary support for the mounting seat 2 and the electric wrench placed on the mounting seat 2, and the power-assisting mechanical arm 1 can be adjusted with multiple degrees of freedom, which is convenient for operators to move and rotate the electric wrench, can reduce the labor intensity of operators, and ensure the stable operation of the production line.
[0043] Further, the lifting arm 15 includes an arm 151 and a first driving source 152, one end of the arm 151 is rotatably connected to the first rotating seat 14, and the other end is rotatably connected to the second rotating seat 16, the tailstock of the first driving source 152 is movably connected to the first rotating seat 14, and the output end of the first driving source 152 is rotatably connected to a connecting piece, and the connecting piece is connected to the arm 151. Specifically, the first driving source 152 can drive the arm 151 to swing in the vertical direction around the rotation connection point between it and the first rotating seat 14 to achieve a lifting action.
[0044] Furthermore, it also includes a locking assembly 3, which includes a locking disk 31 and a second driving source 32. The locking disk 31 is coaxially connected to the first rotating seat 14, and the second driving source 32 is installed on the connecting arm 13, and the output end of the second driving source 32 is perpendicular to the locking disk 31. Specifically, the second driving source 32 can be a cylinder. When the output end of the second driving source 32 is extended and pressed against the locking disk 31, the first rotating seat 14 connected to the locking disk 31 can no longer rotate, thereby realizing the locking function of the corresponding mechanical arm. It is conceivable that the locking assembly 3 can also be set at the position of the main rotating arm 12 and the auxiliary rotating arm 17 to realize the locking function.
[0045] Embodiment 2
[0046] The utility model also discloses a production line, comprising the anti-torque arm for the electric torque wrench as in the first embodiment.
[0047] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
