Abstract

The invention relates to a starfish groove type multi-station conversion device, and belongs to the field of vehicle top transverse beam formwork fixture devices. The starfish groove type multi-station conversion device comprises a base platform, an intermittent rotary mechanism, a formwork turnover fixture and two shaft seats, wherein the formwork turnover fixture is used for positioning a vehicle top transverse beam and comprises a plurality of bolts and a fixture assembly, the fixture assembly comprises a plurality of clamping plates with through grooves and two rotary shafts, and the clamping plates with the through grooves are integrally formed and are mutually spaced according to a 60-degree circumference angle; the two ends of each of the clamping plates with the through grooves are respectively and fixedly connected with one rotary shaft; a plurality of screw holes are formed in one side of each of the clamping plates with the through grooves; the two shaft seats are fixedly connected with the base platform, and the fixture assembly is respectively and rotationally connected with the two shaft seats through the rotary shafts at the two ends; the intermittent rotary mechanism is coaxially and fixedly connected with one rotary shaft. The starfish groove type multi-station conversion device has the advantages that the operation process of batched replacement of the vehicle top transverse beam formwork is convenient and rapid, the production efficiency can be greatly improved, and the operation is safe.

Description

technical field [0001] The invention belongs to the field of clamping devices for vehicle roof beam templates, and in particular relates to a starfish trough type multi-station changing device. Background technique [0002] The roof beams of existing rail cars need to be respectively supported and positioned by a plurality of vertically upward and parallel beam templates during production. Due to the different sizes between different models, the shape and size of the corresponding roof beams are quite different, which leads to the fact that the existing single roof beam template designed for one model cannot be used in common with the roof beams of other models. [0003] When the production line frequently replaces different models, it is necessary to replace many templates that match the next model in batches. The operation process is time-consuming and laborious, and the steps are cumbersome and inefficient. The production schedule is often affected by the time-consuming w...
