Abstract
The utility model relates to a screwing tool for moment of force, which comprises a cylinder and a connecting structure, wherein the connecting structure is fixedly connected on the outer periphery of the cylinder and matched with a fastening tool. The cylinder is axially provided with an open through groove, connecting plates are axially fixedly arranged on the outer periphery of the cylinder on two sides of the open through groove correspondingly, and a bolt structure which is arranged between the corresponding connecting plates is used for applying opposite applied force on the connecting plates to lead the cylinder to radially tightly hold towards the center. The screwing tool for moment of force can be more easily sleeved onto a workpiece to be screwed, the cylinder and the workpiece to be screwed are pressed and fixed by the aid of holding force during assembling of the workpiece to be screwed, and thereby damage of the workpiece to be screwed is avoided.
Description
Technical field
The utility model relates to a kind of device for screwing up, particularly relates to a kind of moment that is used to tighten circular parts and tightens frock.
Background technology
Moving/static contact is one of important spare part in the high-voltage switch gear product; As a kind of parts that need the folding transmission; It requires nature than higher to screw-down torque; But owing to receive the restriction of contact size and structure, can not directly tighten, need do a moment conversion frock and come connection contact and torque spanner with torque spanner.Traditional moment conversion frock only considers that it can play the effect of tightening between contact and torque spanner when design, all be directly to be welded by cylindrical shell and steel plate, has caused the Heavy Weight of frock, consumptive material is many, cost is high; Because weight is heavier, more time-consuming in operation, influenced the manufacturing schedule of product; Simultaneously; Frock need pack into contact in the cylindrical shell when using, and operation inconvenience is prone to scratch contact; Afterwards this structure was improved; Adopt cylindrical shell and bent plate welded structure; The position that is positioned on the bent plate on the cylindrical shell center line is provided with the connector that is used for the fastened tools cooperation; This structure has alleviated the weight of frock, but these two kinds of structures all can only by be located in be used on the cylindrical shell with contact on corresponding screwed hole two small screws that match work, small screw is stressed when moment is tightened excessively is easy to scratch contact or makes the screwed hole distortion.
Summary of the invention
The purpose of the utility model is to provide a kind of moment to tighten frock, tightens the problem that the frock easy damaged is tightened part with moment in the solution prior art.
In order to address the above problem; A kind of moment of the utility model is tightened frock; Comprise cylindrical shell and be connected in the syndeton that being used on the cylindrical shell outer peripheral face cooperates with fastened tools; Said cylindrical shell upper edge axis direction offers the opening groove, and in axial direction correspondence is installed with connecting plate on the cylindrical shell outer peripheral face of these opening groove both sides, is provided with between the said corresponding connecting plate said connecting plate is applied in opposite directions active force and makes the bolt arrangement that cylindrical shell is radially held tightly to the center.
Described bolt arrangement comprises turnbuckle and nut, is equipped with on the said corresponding connecting plate to supply this turnbuckle to pass the bolt penetration hole of back and said nut secure fit.
Described bolt arrangement comprises turnbuckle, and one of them is provided with the screwed hole with this turnbuckle secure fit said corresponding connecting plate above the connecting plate, and another is provided with the bolt penetration hole that supplies this turnbuckle to pass above connecting plate.
On said cylindrical shell, be equipped with to move and be used to make this cylindrical shell and be tightened the screw rod that only revolves cooperation between the part along the cylindrical shell radial direction.
On said cylindrical shell inner peripheral surface, detachably be provided with and be used to prevent that said cylindrical shell from scratching the cushion collar that is tightened part; Radially offer the through hole that supplies this screw rod to pass with the corresponding position of said screw rod on this cushion collar, in axial direction offer the opening groove on the said cushion collar.
Said syndeton, this syndeton comprise that two ends are connected in the bent plate on the cylindrical shell outer peripheral face and are arranged on the bent plate and are in the connector that being used on the cylindrical shell position of center line cooperates with fastened tools.
The utility model is through offering the opening groove on the axis direction of cylindrical shell upper edge; In axial direction correspondence is installed with connecting plate on the cylindrical shell outer peripheral face of these opening groove both sides; Be provided with between the said corresponding connecting plate said connecting plate is applied in opposite directions active force and makes the bolt arrangement that cylindrical shell is radially held tightly to the center; This scheme makes moment tighten frock and is socketed in more easily and is tightened on the part; Be tightened in the process of part in assembling, cylindrical shell and being tightened between the part fastens by holding tightly to defeat, and has avoided being tightened the damage of part.
