Abstract
The utility model discloses a lift sizing block which comprises a platen and a baseplate and the platen and the baseplate correspond up and down and match with each other. The device is characterized in that a lead screw is arranged between the platen and the baseplate, the upper end of the lead screw penetrates through the platen, the end portion of the lower end of the lead screw rotates and matches with the upper end, and is installed on the baseplate, the middle portion of the lead screw is provided with a balancing stand, a guide rod which is parallel to the lead screw penetrates through the balancing stand of the outer side of the lead screw, and the upper end and the lower end of the guide rod are respectively fixed on the platen and the baseplate, the end portion of the upper end of the lead screw is provided with a hand wheel. The device is reasonable in structure and design and is capable of adjusting the evenness of the iron yoke fast and stably and replacing the traditional insulation strut, and at the same time, the device greatly enhances the working efficiency of the steel dowel process of the transformer and ensures the quality of the products better and lowers the requirement of the skill level of the process to operators.
Description
Technical field
The utility model relates to the servicing unit that can regulate the dowel height, relates in particular to a kind of lifting parallels.
Background technology
Transformer core-lamination stack now adopts the stagewise closed assembly, and the height of every grade of iron yoke is different, need to be according to the insulation filler strip of iron yoke height in bottom pad some, iron yoke height and evenness when regulating dowel when changing grade at every turn.
The utility model content
The purpose of this utility model is in order to make up the deficiency of prior art, a kind of lifting parallels is provided, can be fast, the stable iron yoke evenness of adjusting replaces traditional insulating stay, greatly improved simultaneously the operating efficiency of transformer dowel operation, better guarantee product quality, reduced the level of skill requirement of this operation to operating personnel.
The utility model is achieved through the following technical solutions:
A kind of lifting parallels, include pressing plate and the base plate of up and down corresponding matching, it is characterized in that: screw mandrel between described base plate and pressing plate, and pressing plate is passed in the upper end of screw mandrel, the end, lower end is rotatably assorted and is arranged on base plate, and the middle part cooperation of described screw mandrel is equipped with balancing stand, has the guide rod that is parallel to screw mandrel to pass on the balancing stand outside described screw mandrel, and the upper and lower side of guide rod is separately fixed on pressing plate and base plate, and end, described screw mandrel upper end is equipped with handwheel.
Described base plate is provided with the arc cavity, and described screw mandrel bottom face is provided with the arc cavity corresponding with the arc cavity, fastens and be provided with ball between described arc cavity, and described screw mandrel bottom is installed on base plate by clamp.
There are two guide rods that are parallel to screw mandrel to pass on the balancing stand in the described screw mandrel outside.
The cooperation place of described balancing stand and guide rod is welded with respectively the guide pipe of one.
The cooperation place of described balancing stand and screw mandrel is welded with the internal thread guide pipe of one.
Its principle is: by the support bar stable equilibrium frame of two activities, reach the fixedly effect of iron yoke step by step of transformer dowel operation by rotary screw rod adjustment frame height, by wire rod thread adjustment frame height, the method can be fast, fine adjustment balancing stand height changes grade needs when satisfying dowel, can make the lifting parallels in use more firm simultaneously.In the time of can making dowel in process, silicon steel sheet is in sustained height all the time, silicon steel sheet tilt phenomenon at the same level can not appear, stability when guaranteeing dowel drives screw rod and comes fine adjustment balancing stand height by rotating the top handwheel, and this design accurate adjustment is fast propped up plate height and changed grade needs to satisfy dowel.
The utility model has the advantages that:
The utility model reasonable in design, can be fast, the stable iron yoke evenness of adjusting replaces traditional insulating stay, greatly improve simultaneously the operating efficiency of transformer dowel operation, better guaranteed product quality, reduced the level of skill requirement of this operation to operating personnel.
