Description

Assembling tool for voltage regulator

Technical Field

The invention relates to the technical field of assembly, in particular to an assembly tool for a voltage regulator.

Background

The straight rod type pressure regulator comprises a valve body and a cavity, a valve port and an end cover are required to be installed in one direction (part of the pressure regulator is provided with a built-in closing structure and is also installed on one side) during assembly, then the pressure regulator is turned over, and components such as the cavity, a main shaft, a membrane, a spring and the like are installed on the other side. Because the pressure regulator valve body of big nominal diameter is heavier, present pressure regulator producer needs the workman to use the overhead traveling crane to overturn half the valve body of having assembled basically in the assembling process, and this process is more time-consuming. In addition, because the main valve body is large, various assembly operations are finished on a plane workbench, the valve body is not fixed or clamped, the whole valve body is prevented from moving in the assembly process only by the friction of the total amount of the valve body on the workbench, and reliable positioning is lacked.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provide the assembling tool for the voltage regulator, which has a simple structure and is accurate in positioning.

The purpose of the invention can be realized by the following technical scheme: the utility model provides an assembly fixture for voltage regulator, this frock includes that base, vertical support, the fixed mounting on the base bearing frame, one end horizontal axis that fix on the support top connect main shaft, the slip cover in the bearing frame establish the rotating member at main shaft middle part and the cover establish the flange that the main shaft other end is used for fixed voltage regulator valve body, rotating member and flange are respectively through a key and No. two keys and main shaft synchronous revolution, be equipped with the fixed subassembly that matches each other and be used for preventing the main shaft rotation on rotating member and the bearing frame.

The bearing seat comprises a lower cover and an upper cover which are symmetrically arranged, the lower cover and the upper cover are fixedly connected through a bolt group, a plurality of roller bearings are fixed on the inner walls of the upper cover and the lower cover, and one end of the main shaft is fixedly inserted into the roller bearings.

At least two roller bearings are fixed on the inner walls of the upper cover and the lower cover.

The fixing assembly comprises a groove arranged at one end of the rotating member and a protrusion arranged at one end of the bearing seat, the groove and the protrusion are respectively arranged at one ends of the rotating member and the bearing seat which are oppositely arranged and are matched with each other, the number of the groove and the protrusion is even, preferably 4, and the groove and the protrusion are uniformly distributed on the circumferences of one ends of the rotating member and the bearing seat.

Two groups of buckles are symmetrically arranged on the circumference of the rotary part, the two buckles are opened towards the flange direction, rotatable rectangular fixing frames are arranged at the top and the bottom of the bearing seat, the fixing frames can rotate around the first side, in addition, the bulge of the bearing seat is inserted into the groove of the rotary part, and the second side opposite to the first side in the fixing frames is clamped into the buckles.

And a handle for pushing the rotating member to move along the main shaft is arranged on the outer wall of the rotating member.

The support is made of I-shaped steel. The area of the bottom plate of the tool base needs to be large enough, and the support part needs to adopt reasonable materials and structures, so that the whole tool can bear the overturning moment generated by the self weight of the main valve body.

The working process of the invention is as follows:

before the assembly begins, firstly, the handle is pulled to rotate and slide along the main shaft until the protrusion of the bearing seat is inserted into the groove of the rotating part, the fixing frame is matched, the second side of the fixing frame is clamped into the buckle, and the whole tool is fixed at the moment.

And fixing one side of the valve body on the flange, enabling the side needing to be assembled to face upwards, and then finishing the related assembly of the side of the main valve body.

The fixing frame is taken out of the buckle, the rotating part is moved along the main shaft in the opposite direction through the handle until the groove is completely separated from the protrusion, then the rotating part rotates 180 degrees through the handle, meanwhile, the rotating part rotates the flange 180 degrees through the main shaft, at the moment, the valve body rotates 180 degrees in the same way, and the surface to be assembled on the other side is upward. And finally, moving the rotating part, embedding the groove and the protrusion again, and fixing the buckle through the fixing frame.

At this time, the other side of the valve body, which needs to be assembled, faces upwards, and after the subsequent assembly operation is completed, the valve body is detached from the flange.

Compared with the prior art, the beneficial effects of the invention are embodied in the following aspects:

(1) the valve body is assembled only by one-time clamping, and the valve body does not need to be turned over by a crane or other equipment in the process, so that the assembly efficiency is improved;

(2) the valve body is arranged on the tool through the bolt and the nut, so that the valve body is reliably positioned in the assembling process, the assembling precision can be improved, and the safety of assembling operation is improved.
