Description

Technical Field

[0001] The invention relates to the technical field of tooling and fixtures, and in particular to a quick positioning tooling. Background Art

[0002] In the fields of mechanical manufacturing, measurement, machine tools, and robot automatic production lines, datum is a widely used concept. Datum is used to determine the points, lines, and surfaces on which the superiors and relationships of objects are based. In the field of mechanical industry, we refer to the datum as the zero point. In processing or measurement, the zero point of the workpiece must be determined first, and then processing or measurement is performed based on the zero point. However, during the processing, the parts will not remain stationary. From one process to another, from one machine tool to another, the zero point needs to be re-aligned, and a lot of auxiliary work will be done, resulting in a lot of downtime and reduced work efficiency.

[0003] In the prior art, the above problems are solved by using a rapid positioning tool. The rapid positioning tool is an independent positioning and locking device that can ensure that the zero point remains unchanged when parts are switched between workstations, processes, and machine tools. This saves the time of re-adjusting the zero point and greatly improves work efficiency. Since the rapid positioning tool is particularly precise, the positioning support surface needs to be kept highly clean. Any fine particles retained may cause deviations in the system accuracy, so attention must be paid to cleaning. During assembly, workers are required to clean the positioning support surface with a high-pressure air gun to keep the positioning support surface clean, which will result in low assembly efficiency and also pose a safety hazard.

The rotating sleeve 51 is sleeved on the base 41 and can rotate along the axis of the base 41 and slide up and down. The bracket 52 is installed in the limiting groove 511, and the limiting groove 511 is used to limit the relative rotation of the bracket 52 and the rotating sleeve 51, so that the bracket 52 can rotate synchronously with the rotating sleeve 51. The bracket 52 can also slide up and down in the limiting groove 511. The first wiping assembly 53 is installed on the bracket 52, and can slide up and down along the axis of the bracket 52, and can also rotate with the bracket 52.

[0070] Preferably, the bracket 52 includes a limit plate 521, and the limit plate 521 is installed in the limit groove 511 to limit the relative rotation of the bracket 52 and the rotating sleeve 51, so that the bracket 52 can rotate synchronously with the rotating sleeve 51; at the same time, the limit plate 521 can slide up and down in the limit groove 511, so that when the first wiping component 53 and the second wiping component 54 are in contact, the limit plate 521 slides into the limit groove 511 to achieve a retreat action, thereby ensuring that the second positioning reference end face 2 can contact the first positioning reference end face 1 to achieve precise positioning.

[0071] Preferably, the bracket 52 also includes a second spring 522, one end of the second spring 522 is fixedly connected to the limit plate 521, and the other end is fixedly installed in the limit groove 511, and the second spring 522 is used to apply an elastic thrust to the limit plate 521.
