Abstract
Description
Technical Field
[0001] This utility model relates to the field of automated inspection fixture technology, and in particular to a spherical expansion pin for fixture positioning. Background Technology
[0002] When inspecting round pipes, the pipes need to be installed and positioned. Existing positioning fixtures can only position pipes of a single size and cannot be adjusted. When the size of the pipe changes slightly, it cannot be firmly positioned. To solve the above problems, a spherical expansion pin for fixture positioning is proposed. Utility Model Content
[0003] To address the aforementioned technical problems, this utility model provides a spherical expansion pin for positioning a gauge, characterized by comprising a base, a first cylinder, a support base, a positioning inner core, an adjustment hole, a movable ball, a mounting base, a second cylinder, a connecting rod, a circular outer sleeve, a stepped portion, and an observation port. The first cylinder is mounted on the base, the support base is mounted on the first cylinder, the positioning inner core is mounted on the support column, the adjustment hole is located on the positioning inner core, and a movable ball is contained within the adjustment hole. The mounting base is mounted on the support base, the second cylinder is located below the mounting base, the connecting rod is mounted on the second cylinder, the circular outer sleeve is mounted on the connecting rod, the stepped portion is located on the circular outer sleeve, and the observation port is located on the circular outer sleeve.
[0004] Furthermore, a first cylinder is fixedly installed on the base, the first cylinder is connected to an external controller, a support is fixedly installed at the output end of the first cylinder, a positioning inner core is fixedly installed at the front end of the support, an installation base is fixedly installed below the support column, a second cylinder is fixedly installed on the installation base, the second cylinder is connected to an external controller, a connecting rod is fixedly installed at the output end of the first cylinder, the connecting rod is fixedly connected to a circular outer sleeve, and the positioning inner core is sleeved with the circular outer sleeve;
[0005] Furthermore, there are three adjustment holes, evenly distributed on the surface of the positioning inner core, and the three adjustment holes are located on the same plane. The adjustment holes are circular, and each adjustment hole contains a movable ball. The diameter of the adjustment hole is smaller than the diameter of the movable ball.
[0006] Furthermore, the circular outer jacket has a stepped portion in the middle, the inner diameter of the front end of the circular outer jacket is larger than the inner diameter of the rear end, and the size of the rear end of the circular outer jacket is the same as the outer diameter of the positioning inner core.
[0007] Furthermore, there are several observation ports, which are evenly distributed on the surface of the circular outer casing.
[0008] The beneficial effects of this utility model are:
[0009] This invention fixes the base to the testing fixture with bolts, controls the first cylinder to extend to the appropriate position for testing, inserts the pipe into the positioning core of the support base, and tests the pipe. When the pipe size is inaccurate or too small, the second cylinder of the mounting base extends, driving the connecting rod forward, causing the circular sleeve fitted on the positioning core to move forward. At this time, the three movable balls contact the stepped part of the circular sleeve, and simultaneously move the positioning core in the adjustment hole in the direction of the center, clamping and positioning the smaller pipe. When the pipe size has slight changes, it can be firmly positioned, facilitating testing and improving the scope of application. Attached Figure Description
