Problems solved by technology

Tolerances are prone to occur during the pin manufacturing process, and the pins cannot be closely matched with the holes on the workpiece, resulting in the shaking of the workpiece and the inability to accurately position it, thus affecting the processing or detection accuracy of the workpiece
In addition, the pin is only suitable for holes in the workpiece that match the size of the pin, resulting in a smaller range of application for the pin

Embodiment Construction

[0016] see figure 1 , the positioning mechanism 100 of this embodiment is used to position a workpiece (not shown) with a positioning hole (not shown). The positioning mechanism 100 includes a base 10 , an expansion assembly 30 installed on the base 10 , and a cover plate 50 sleeved on the expansion assembly 30 and fixedly installed on the base 10 . The positioning mechanism 100 is powered by an air source or a liquid source. In this embodiment, the positioning mechanism uses an external air source as power.

[0017] Please also see Figure 2 to Figure 4 , the base 10 is used to connect with an external air source. An L-shaped fluid channel 11 is opened on the base 10 . The fluid channel 11 includes an inlet hole 112 and a connecting hole 113 vertically connected to the inlet hole 112 . The inlet hole 112 of the base 10 is connected to the external air source through the speed regulating joint 115 , so that the gas provided by the external air source enters the fluid chann...

Abstract

An expansion assembly includes a connecting plug, a deformable sealing sleeve, and an expansion sleeve. The connecting plug defines a through hole configured for air flow to pass therethrough. The deformable sealing sleeve is sleeved on the connecting plug. The expansion sleeve houses the deformable sealing sleeve and is sleeved on the connecting plug. The expansion sleeve comprises a number of resilient arms separated from each other. When airflow is introduced into the deformable sealing sleeve via the connecting plug, the deformable sealing sleeve is expanded, causing the number of resilient arms of the expansion sleeve to expand outward. A positioning mechanism employing the expansion assembly is also disclosed.

Description

technical field [0001] The invention relates to a positioning mechanism and an expansion assembly adopted therefor. Background technique [0002] When the workpiece is positioned on the workbench during the production process, pins are often used to position the workpiece on the workbench for precise processing or testing. Usually the pin size is designed according to the lower limit tolerance of the hole size on the workpiece. Tolerances are prone to occur during the pin manufacturing process, and the pins cannot be closely matched with the holes on the workpiece, resulting in the shaking of the workpiece and the inability to accurately locate it, thereby affecting the processing or detection accuracy of the workpiece. In addition, the pin is only suitable for holes on the workpiece that match the size of the pin, resulting in a smaller range of application for the pin. Contents of the invention [0003] In view of the above, it is necessary to provide a positioning mec...
