Description

Technical Field

[0001] The utility model relates to the technical field of a tensioning tailstock, in particular to a tensioning tailstock for a linear module. Background Art

[0002] The linear module is an automated upgrade unit following the linear guide, linear motion module, and ball screw linear transmission mechanism. The tensioning tailstock of the linear module is the base at the tail end of the linear module that can adjust the tightness of the pulley belt.

[0003] According to the description of the tensioning tailstock of the linear module disclosed in the patent network (authorization announcement number: CN 217736184 U), "The utility model discloses a tensioning tailstock of a linear module, which includes a base, a wheel set installed in the base and used to connect with a synchronous belt, and a tail cover fixed to the outside of the base and covering the wheel set. The wheel set includes a shaft body and a synchronous wheel rotatably mounted on the outer periphery of the shaft body through a bearing, and both ends of the shaft body extend out of the two sides of the synchronous wheel; the end of the shaft body is arranged in a slide groove in the base, and the tail cover is penetrated by a tensioning bolt used to connect with the end of the shaft body and can be used to adjust the relative position of the end of the shaft body in the slide groove. When it is necessary to adjust the relative position of the wheel set in the base, the end of the shaft body can be driven to move in the slide groove by a spiral tensioning bolt to adjust the relative position of the wheel set, thereby adjusting the tension of the synchronous belt to meet different use requirements. In addition, the utility model does not need to use a clamp frame to assemble the wheel set, so that the volume of the entire tensioning tailstock is made smaller, so as to develop towards miniaturization, and the overall structure is simpler and the market competitiveness is stronger."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use, the utility model can adjust the position of the wheel set in the base by sliding the end of the shaft body inside the slide groove, and the tightening bolt can be turned to make the end of the shaft body slide to adjust the tension of the synchronous belt. However, in actual use, since the tensioning tailstock needs to rotate two tightening bolts when adjusting the tension of the synchronous belt, and the two tightening bolts need to be manually adjusted separately and the number of turns they need to be consistent, the operation of adjusting the tension of the synchronous belt is cumbersome and inconvenient. Therefore, it is necessary to improve a tensioning tailstock for a linear module to solve the above problem. Utility Model Content
