DETAILED DESCRIPTION

[0020] The preferred solution is Figures 1 to 5 As shown, a large lathe roller device with a load sensor is composed of two roller assemblies, a lower bracket and an upper bracket. The roller can perfectly contact the large workpiece through the jack and the locking bolt. There is no need to manufacture a variety of additional fixed brackets. It is flexible to adjust and has good adaptability. It can be applied to workpieces of most diameters, which is beneficial to reducing the processing cost of large workpieces and is simple and convenient to operate.

[0021] In this embodiment, the lower bracket 1 has a threaded hole on the side of the lower bracket 1. The threaded hole on the side is convenient for adjusting the center line position of the two rollers. The upper bracket 2 has a plurality of threaded holes on the upper bracket 2. The threaded holes on the upper bracket 2 are convenient for locking the screws to lock the center height of the rollers, thereby preventing the center height of the rollers from decreasing due to excessive weight of the workpiece. The roller assembly 3 includes a roller shaft 32. The roller shaft 32 is a pin-type load sensor. The data line leading out from the end is connected to the display screen to display the load in real time. The roller shaft 32 is equipped with a bearing at the step and is installed as a whole in the roller cylinder 31. The end of the roller shaft 32 is covered with a spacer 33 to prevent the bearing from moving. A cover 34 is installed at the end of the roller cylinder 31 by bolts to prevent dust and iron cuttings from entering the bearing.

[0022] The working principle and use process of the utility model are as follows: the upper bracket is raised to the surface of the workpiece by the manual jack installed inside the lower bracket. By adjusting the side bolts 4 of the lower bracket, the fixing center line of the workpiece is ensured to be consistent with the center lines of the two rollers. After the adjustment is in place, the bolts 5 of the upper bracket are locked to lock the upper bracket and prevent it from sinking. When processing the workpiece, you must always pay attention to the load table. If there is a large gap, you must readjust the workpiece and the roller device.

[0023] The above embodiments are only preferred technical solutions of the present invention and should not be regarded as limitations of the present invention. The protection scope of the present invention shall be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
