2results about How to "Reduce processing defect rate" patented technology

The application relates to a heat exchanger, comprising a heat exchange unit and a connecting unit, the number of the heat exchange units is at least two, each heat exchange unit comprises a header section arranged along a first direction, and the plurality of header sections are coaxially and sequentially arranged at intervals; at least part of the connecting units is arranged between two adjacent header sections along the first direction, and the two ends of the connecting unit are respectively communicated with the corresponding side header sections. The application connects the header sections in the adjacent heat exchange units by using the connecting unit, so that a plurality of shorter header sections can form a longer header section. Compared with the heat exchanger without the connecting unit, the plurality of header sections in the heat exchanger of the application are shorter, therefore, each shorter header section is not prone to bending deformation during production, and the plurality of shorter header sections can reduce the processing difficulty and the product processing failure rate when the heat exchanger is manufactured.

This utility model discloses a tooling for processing the top cover of a spinning assembly, relating to the field of processing tooling. It includes: a clamping and positioning seat for assembling the top cover; a positioning device symmetrically mounted on the clamping and positioning seat for positioning the top cover; and an indexing chuck that cooperates with the clamping and positioning seat and is used to adjust the angle of the clamping and positioning seat. This tooling for processing the top cover of a spinning assembly allows for rapid positioning of the workpiece by inserting the top cover into the clamping and positioning seat, positioning the top cover by the positioning device, and rotating it to the required angle using the indexing chuck. This enables the machining of oblique holes and countersunk holes in a machining center. The oblique holes produced by this tooling have stable angles, improving processing efficiency and significantly reducing the defect rate caused by inaccurate clamping and positioning. Through the synergistic effect of the clamping and positioning seat and the positioning device, rapid and accurate positioning of the workpiece is achieved.
