Problems solved by technology

Its disadvantages are: the reliability of the magnetic sleeve on the tightening shaft to transport the bolts is low, and the participation of industrial robots greatly increases the cost of the entire system
[0007] In addition, the automatic hole-finding technology in the existing conventional technology can only roughly find the position of the screw hole, and cannot achieve the accuracy of automatically aligning the bolt directly to the screw hole and tightening (the error of the bolt directly aligning with the screw hole cannot be greater than 0.1mm ), due to the large error, it is quite strenuous in the process of aligning the bolts to the screw holes, and it is also very easy to cause damage to the bolts or screw holes, resulting in a decrease in the final tightening quality

Embodiment 1

[0061] Such as figure 1 with figure 2 Shown: This embodiment discloses a bolt tightening system capable of accurately positioning the axis of a screw hole, which includes a rotating platform 9, a centering cone shaft 20, a bolt clamping device and a tightening device.

[0062] In detail, the rotating platform 9 is provided with a V-shaped rotating frame, and the V-shaped included angle of the V-shaped rotating frame is fixedly connected with the rotation center of the rotating platform 9.

[0063] The centering cone shaft 20 and the bolt clamping device are respectively arranged at the ends of the two arms of the V-shaped rotating frame, and the axis of the centering cone shaft 20 and the axis of the bolt clamped by the bolt clamping device The distances from the central axis of rotation are all equal.

[0064] The axis of the centering cone shaft 20, the axis of the bolt held by the bolt clamping device, and the rotation center axis are parallel to each other in space.

[0065] The ...

Embodiment 2

[0116] Combine figure 1 with figure 2 , The bolt tightening system capable of accurately positioning the axis of the screw hole of the present invention includes a bottom plate 1, a tightening device and a positioning device horizontally installed on the bottom plate, the tightening device and the positioning device are arranged in parallel left and right, and a rotating platform 9 is installed at the end of the positioning device. , The biaxial cylinder 2 provides the forward and backward feeding movement of the rotating platform 9 through the passive rotating shaft 6.

[0117] Such as figure 2 As shown, the bottom plate 1 is equipped with a tightening device, a biaxial cylinder 2 and a passive rotating assembly.

Abstract

The invention relates to a bolt tightening system that can accurately locate the axis center of a bolt hole, including a rotating platform, a centering cone shaft, a bolt clamping device and a tightening device; the rotating platform is provided with a V-shaped rotating frame, and the V-shaped The V-shaped included angle of the rotating frame is fixedly connected to the rotation center of the rotating platform; the centering cone shaft and the bolt clamping device are respectively provided at the ends of the two arms of the V-shaped rotating frame, and the centering cone The axis of the shaft and the axis of the bolt clamped by the bolt clamping device are all at the same distance from the axis of the rotation center; the axis of the centering cone shaft, the axis of the bolt clamped by the bolt clamping device and The axes of the rotation centers are parallel to each other in space. The bolt tightening system provided by the present invention that can accurately locate the axis center of the bolt hole can further accurately locate the axis center of the bolt hole, quickly align the bolt with the bolt hole, and complete the tightening work of the bolt.

Description

Technical field [0001] The invention belongs to the technical field of bolt tightening, and particularly relates to a bolt tightening system capable of accurately positioning a screw hole axis. Background technique [0002] With the continuous improvement of automation technology, the development of bolt assembly control technology and bolt assembly manufacturing equipment in industrial production is changing with each passing day. At present, various types of electric wrenches, pneumatic wrenches or hydraulic wrenches are widely used in the market to carry out bolt assembly work, and embedded in the automatic wrench can be used for torque control, torque-angle control, yield tightening control, elongation control, etc. The threaded connection assembly controller of the control mode realizes the precise control of the bolt tightening process. This method changes the disadvantages of high labor intensity and low tightening quality in the traditional manual wrench bolt assembly, a...
