Problems solved by technology
[0002] At present, domestic sewing machine manufacturers generally use manual assembly of the casing and bottom plate. Due to the high assembly precision and the need for very precise hand feeling control during the assembly process, only a few experienced technical personnel can complete it, which seriously restricts the output and quality of products.

Embodiment Construction
[0029] pass below Figure 1 to Figure 15 As well as listing some optional embodiments of the present invention, the technical solutions (including preferred technical solutions) of the present invention are further described in detail. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0030] like Figure 1 to Figure 15 As shown, the screwing machine designed by the present invention to automatically correct the position of the casing bottom plate includes a frame 1 on which a clamp 2, a floating mechanism 3, a tightening device 4, a measuring device 5, and a driving device 6 are arranged. The parts are pulled from the roller table to the position of the fixture 2 by the push-pull material device in the frame...

The invention relates to a tightening machine capable of automatically correcting the position of a bottom plate of a sewing machine shell. The tightening machine is characterized in that the tightening machine comprises a rack and a fixture for positioning and clamping the machine shell and the bottom plate; the rack is provided with a floating mechanism for positioning the position of the bottom plate, a tightening mechanism for assembling the machine shell and the bottom plate, a material pushing and pulling device for driving a workpiece to reciprocate between a feeding station and a tightening station, a measuring device for measuring the position of the bottom plate of the machine shell and a driving device for adjusting the position of the machine shell; the driving device is used for driving the machine shell fixture to adjust the position of the machine shell according to a measured value of the measuring device; and the floating device is used for converting the positioning reference of the fixture into the assembling reference of the tightening mechanism. The reference is converted through the floating device, and the positioning reference sum of the fixture is converted into the assembling positioning reference. Compared with an existing manual assembly mode, the production efficiency is greatly improved, meanwhile, assembly errors are avoided, and large-scale production can be achieved; and moreover, parts with different sizes can be used, and the universality is good.
Description
technical field [0001] The invention belongs to the technical field of assembly, in particular to the assembly of sewing machines, in particular to an automatic correcting screwing machine for the position of the bottom plate of a sewing machine casing. Background technique [0002] At present, domestic sewing machine manufacturers generally use manual assembly of the casing and bottom plate. Due to the high assembly accuracy and the need for very precise hand feeling control during the assembly process, only a few experienced technical personnel can complete it, which seriously restricts the output and quality of products. Contents of the invention [0003] In view of the problems existing in the background technology, the object of the present invention is to provide a sewing machine casing bottom plate automatic correction and assembly, high production efficiency, and high quality finished product. [0004] In order to achieve the above object, the sewing machine casing...
