Problems solved by technology
However, the welding tool used to assemble the AS-type electric hoist reel support in the past is a single-standard welding tool, and the coaxiality deviation at both ends can reach up to 4mm, which cannot meet the high-precision requirements of high-end equipment at all. Moreover, some The position of the tooling workpiece cannot be changed after installation, it is inconvenient to use, the processing operation is cumbersome, the labor intensity is high, and the product quality is not guaranteed

Embodiment Construction
[0026] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples, and detailed descriptions are as follows with accompanying drawings:
[0027] A double-reference welding tool for assembling electric hoist reel bracket, which is supported by bed 14, headstock 1, slide box 11, tailstock device 8, fixed frame device, bearing side support and positioning device 3, and reducer side support and positioning Composition of device 5. The bed is provided with a guide rail 13 and a screw 12 on it. The headstock is fixed on one end of the bed, and the slide box and the headstock are relatively slidingly mounted on the other end of the bed. The screw can slide left and right on the guide rail to adjust the bearing side support positioning device and the reducer side support positioning device. distance. The tailstock device is fixedly mounted on the top of the slide box through the tailstock connecting plate 9...

The invention belongs to the field of hoisting machinery machining equipment, and relates to a two-datum welding fixture for assembling an electric hoist drum support. The two-datum welding fixture comprises a body, a spindle box, a sliding box, a tailstock device, a fixing frame device, a bearing side support positioning device and a speed reducer side support positioning device, the spindle box is fixedly mounted at one end of the body, the sliding box and the spindle box are mounted at the other end of the body in a relatively sliding manner, the tailstock device is fixedly mounted on the sliding box, the fixing frame device and the spindle box are fixedly mounted on the same side of the body, and the bearing side support positioning device and the speed reducer side support positioning device are oppositely and fixedly mounted on the spindle box and the tailstock device respectively. The two-datum welding fixture for assembling the electric hoist drum support is scientific and reasonable in structural design and highly innovative, and has the advantages of convenience in operation, low labor intensity, two-datum positioning, positioning accuracy, quality guarantee and the like.
Description
Technical field [0001] The invention belongs to the field of hoisting machinery processing equipment, and particularly relates to a double-reference welding tool for assembling an electric hoist reel bracket. Background technique [0002] At present, my country's equipment manufacturing industry continues to develop, and the equipment produced is gradually developing from the original extensive type to the high-end refined type. In the process of high-precision equipment production and assembly, the requirements for assembly accuracy are correspondingly continuously improved. For example, the AS type electric hoist reel bracket requires that the coaxiality at both ends is ≤0.2mm within the length of 1766mm, which is a substantial improvement compared to the original coaxiality deviation standard. This requires corresponding assembly tooling to meet the requirements of high-precision processing and assembly. The welding tool used in the past for assembling the AS-type electric ho...
