Abstract

The invention relates to positioning tooling for a mechanical connecting arm. The positioning tooling for a mechanical connecting arm comprises a base plate and a support frame. The support frame is located on the upper end face of the base plate, the support frame is provided with a hook positioning module, a side compression module, a center compression module and a floating positioning module.The hook positioning module comprises a first positioning module, a barb and a sliding driving rod. The side compression module comprises side support plates, bolts and pressing blocks, and the pressing blocks are located on the bolts at the top ends of the side support plates. The center compression module comprises a second positioning block and a compression rod, the second positioning block isprovided with support rods and limit support blocks, and the compression rod is hinged with the support rods. The floating positioning module comprises floating positioning pins, and the floating locating pins are connected with the top ends of the support frame through fixing blocks. According to the positioning tooling for the mechanical connecting arm, the mechanical connecting arm can be subjected to firm and accurate integral positioning clamping, clamping is convenient and timesaving, meanwhile, the fact that deviation is not produced due to multi-point multi-direction force bearing inthe processing process is ensured.

Description

technical field [0001] The invention relates to the field of fixtures required for mechanical processing, in particular to a positioning tool for a mechanical connecting arm. Background technique [0002] The mechanical connecting arm is an important part of the arm bending mechanism on heavy industrial machinery. The mechanical connecting arm is a non-standard part, and its two ends are provided with bearing through-hole structures. The cross-section is irregular I-shaped, and the overall structure is relatively complicated. [0003] Because the overall structure of the mechanical connecting arm is relatively complex, when performing machining operations in the CNC machining center, it is necessary to use a variety of tools to process the mechanical connecting arm at multiple places and from multiple angles. Therefore, during the entire processing process, the mechanical connecting arm There are many stress points and directions. [0004] Since the structure of the mechan...
