The invention discloses a double-end-floating self-centering clamp which comprises a base positioning device and a centering device. The base positioning device is located on the lower portion of the centering device and comprises a base, a centering base, a positioning ring and a clamp body, the centering base is sleeved with the positioning ring so that it can be guaranteed that the base and the centering base are concentric, and the base and the centering base are fixed to the clamp body. The centering device comprises a lower centering device body used for correcting the lower end, an upper centering device body used for correcting the upper end and a central transmission device for controlling the centering device to conduct correcting. The double-end-floating self-centering clamp has the advantages that an upper bearing hole and a lower bearing hole can be corrected at the same time, and the machining requirements of the class of parts can be met.
Description
technical field [0001] The invention relates to a floating self-centering fixture, in particular to a floating self-centering fixture with both ends. Background technique [0002] In process equipment, self-centering fixtures are widely used. Generally, self-centering fixtures can correct a hole. However, there are gear shaft holes in some shell parts. When the upper and lower bearing holes need to be corrected, the ordinary self-centering fixture only corrects the lower or upper hole. Sometimes there is no way to meet the processing requirements, resulting in the uncorrected one. The hole machining allowance is uneven and cannot meet the quality requirements. Contents of the invention [0003] The purpose of the present invention is to provide a floating self-centering fixture at both ends to solve the common problem in the prior art that the upper and lower bearing holes cannot be corrected at the same time. [0004] To achieve the above object, the present invention i...
