Technical Field
The utility model belongs to the technical field of the forming machine transmission of clod wash, concretely relates to high-speed roll dashes drive gear axial positioning structure.
Background
The cold-bending forming machine is a plastic processing machine for continuously and transversely bending metal plate strips such as coiled materials, strip materials and the like through a plurality of forming rollers which are sequentially arranged to manufacture a section with a specific section.
With the rapid development of the field of domestic machining, in order to improve production benefits, most of parts realized by a punch press are gradually replaced by cold bending forming equipment, and some parts requiring higher precision also gradually realize cold bending processing, but because cold bending processing is realized by manufacturing a forming device into a rolling die and realizing cold pressing processing in a gradual and progressive forming mode, the processing mode needs high-speed rolling punching equipment to operate, and a driving shaft drives a driven shaft to realize the operation of the forming die, so that the parts are processed, when the parts are formed by rolling punching, the default driving state is that the driving shaft and the driven shaft synchronously operate, but in an actual state, a small gap exists between a driving gear and a driven gear, and the existence of the gap can cause the following technical problems: 1. the gears are quickly abraded, and the gear clearance is large, so that the driving gear and the driven gear cannot accurately and synchronously run; 2. the temperature rise that the gear box during operation produced makes gear shaft axial linear expansion direction can not accurate control, directly leads to the product precision poor.
In view of the above technical problems, it is very necessary for those skilled in the art to design a positioning structure capable of achieving precise engagement adjustment of the driving gear and the transmission gear to overcome the drawbacks of the prior art.
Disclosure of Invention
In order to overcome the defects in the prior art, the utility model provides a high-speed roll towards drive gear axial positioning structure, its structural design is simple, novel, sets up the adjustment that positioner realized two gear precision through the cooperation on driven gear.
In order to achieve the technical purpose, the utility model adopts the following scheme: the utility model provides a high-speed roll towards drive gear axial positioning structure, its includes the drive storehouse, the drive storehouse in be provided with drive assembly and driven assembly, be provided with the driven gear meshing on drive gear and the driven assembly on the drive assembly, driven gear on be provided with drive tooth clamping device, it can realize the centre gripping of rotation adjustment realization to drive gear, realizes the zero clearance synchronous revolution of driven gear when drive gear rotates.
And the side part of the driven gear is provided with a fixing groove, and the fixing groove is used for fixing the driving tooth clamping device.
The driving tooth clamping device is of a disc-shaped gear ring structure, a combination hole is formed between the driving tooth clamping device and the fixing groove, and rotation adjustment of the driving tooth clamping device in the fixing groove can be achieved.
The teeth of the movable tooth clamping device are arranged in a spiral structure, and the spiral angle of the movable tooth clamping device is set within the range of 9-9.5 degrees.
The utility model has the advantages that: the utility model discloses an above setting, it is provided with drive assembly and driven assembly in the drive storehouse, is provided with the driven gear meshing on drive gear and the driven assembly on the drive assembly, is provided with drive tooth clamping device on the driven gear, and it can realize the centre gripping of rotation adjustment realization to drive gear, realize when drive gear rotates with driven gear's zero clearance synchronous revolution. The transmission system that this kind of structure set up can effectual solution gear wear fast, gear clearance is big, leads to the problem that action wheel and driven gear can not accurate synchronous operation, avoids the temperature rise that the gear box during operation produced simultaneously, prevents that the gear shaft axial linear expansion direction that the high temperature caused can not accurate control, leads to the problem that the product precision is poor.
