Description

Central vise screw positioning seat combined structure

This creation provides a technical field of center vise, especially it provides a combination structure of center vise screw positioning seat. The screw positioning seat directly shows the first concave round hole of the largest diameter, and the positioning seat side Cover sealing positioning, the first concave round hole has obvious technical characteristics, which can be easy to process and reduce tool wear, effectively improve processing accuracy, and create the best center positioning effect and high accuracy.

Press, refer to the first, second, and third figures, which are the three-dimensional exploded, three-dimensional, and front-view schematic diagrams of the upper and lower positioning blocks of the "center vise device" of the creator of the previous application No. 109200617. The groove 13 is set in the middle position after the upper and lower positioning blocks 11 and 12 are assembled. In order to ensure the accurate center position of the annular positioning groove 13 after processing, it is necessary to position the upper and lower After the blocks 11 and 12 are assembled, the annular positioning groove 13 can be processed. Only the T-type milling cutter 14 can be used for processing. Also, the T-type milling cutter 14 is characterized by a large circumference at the blade position, and the axis The shaft diameter of the shaft is small, which causes the shaft to bear a considerable shear force, and also makes the T-type milling cutter 14 easy to break. In addition, the T-type milling cutter 14 is quite expensive, so in order to reduce Losses are generally processed by upper and lower positioning blocks 11 and 12 with lower hardness, and materials with higher hardness cannot be used for processing. There is a need for improvement. However, this creation can be processed with only ordinary milling cutters (as shown in the fourth and fifth pictures), no expensive T-shaped milling cutter 14 is needed, and there is no tool breaking problem; therefore, this creation is not only convenient for processing, but also reduces tools Wear, effectively improve the processing accuracy, and create the best center positioning effect and high accuracy.
