Description
Technical Field
The invention belongs to the field of valve assembling devices, and particularly relates to a bidirectional mounting device for mounting a valve shaft and a valve plate of a butterfly valve.
Background
In the butterfly valve manufacturing industry, at present, manual hammering is mostly adopted for the installation of a valve shaft and a valve body, the operation mode is low in efficiency, a large amount of labor is consumed, the applicability is small, and the assembly of a large-size butterfly valve cannot be realized.
In order to solve the above problems, some manufacturers have developed assembling equipment using a hydraulic cylinder as a power source, and the assembling equipment generally comprises a worktable, wherein the front end of the worktable is provided with the hydraulic cylinder, the end part of a piston rod of the main hydraulic cylinder is provided with an impact head, the impact head is arranged facing the worktable, and the rear end of the worktable, which is opposite to the impact head, is fixedly provided with a limit block. In the assembling process, the valve body is placed on the upper end face of the workbench, and after the valve plate and the valve shaft are placed at proper positions, the hydraulic cylinder is opened to impact and beat.
The device greatly improves the assembly efficiency, saves labor, simplifies the assembly process, but has certain limitation in the actual assembly process. The butterfly valve is not only in a single valve shaft structure, but also in a structure formed by assembling two half shafts and a valve plate, the device cannot be assembled for one time aiming at the structure of the two half shafts, and after one half shaft is assembled, the valve needs to be integrally hoisted and rotated for 180 degrees, and then secondary installation is carried out.
The above operation method has complicated process, and after the valve is integrally rotated, the angle between the other half shaft and the valve body and the valve needs to be readjusted, and if the angle adjustment is deviated, the valve body or the half shaft is easily damaged. In addition, in the process of impact, impact force is transmitted into the valve plate through the valve shaft, the valve plate is easy to rotate or misplace under the action of torsion, and at the moment, the valve plate needs to be leveled. The butterfly valve assembled by the above devices is generally a large-sized valve, and therefore, the leveling process for the valve plate still needs more manual work.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provides a bidirectional mounting device for mounting a valve shaft and a valve plate of a butterfly valve, which has a reasonable structure and bidirectional processing and does not need manual work to participate in valve plate adjustment.
The technical scheme adopted by the invention is as follows:
the utility model provides a two-way installation device is used in installation of butterfly valve shaft valve plate, includes the workstation of a bar, be used for placing the valve body of treating the installation in the workstation up end, main hydraulic cylinder is installed to the front end of this workstation, main hydraulic cylinder's piston rod sets up towards the workstation, and the piston rod tip of this main hydraulic cylinder installs impact head, its characterized in that: the utility model discloses a hydraulic cylinder, including workstation, main hydraulic cylinder, workstation, door type frame, vertical pneumatic cylinder, vertical setting of piston rod tip of two vertical pneumatic cylinders stretches out by door type frame bottom, and the pressure head is installed respectively to the piston rod tip of these two vertical pneumatic cylinders respectively.
And the horizontal both sides of workstation are inwards made a spout respectively, install a set of pulley respectively in the terminal surface of door type frame both sides and spout homonymy, every pulley all slides and inlays the dress in the spout of homonymy, and door type frame can follow the longitudinal direction reciprocating motion of workstation through the pulley.
And a cross beam is integrally arranged at the upper end of the door-shaped frame along the horizontal direction, and the vertical hydraulic cylinders are symmetrically arranged on the left side and the right side of the cross beam.
The invention has the advantages and positive effects that:
in the invention, improvement is carried out on the basis of the existing equipment, and an auxiliary hydraulic cylinder is additionally arranged to replace the original limiting device. When the single shaft assembly is carried out, the auxiliary hydraulic cylinder abuts against the rear end part of the valve body, and the valve shaft can be beaten into the valve body through the main hydraulic cylinder; when the two half shafts are assembled, the main hydraulic cylinder and the auxiliary hydraulic cylinder work alternately, and the two half shafts can be assembled at one time without hoisting and angle adjustment of the valve; the valve plate can be adjusted in valve plate both sides to the corresponding pressure head down of two vertical pneumatic cylinders cooperation, and the valve plate is to which side perk, then starts the vertical pneumatic cylinder of homonymy and pushes down the adjustment, and reciprocal marching is realized through the pulley to the door type frame, and then adjusts the position between vertical pneumatic cylinder and the valve plate, increases the adaptability of device, can be applied to not unidimensional valve.

Detailed Description
The present invention is further illustrated by the following examples, which are intended to be illustrative, not limiting and are not intended to limit the scope of the invention.
A two-way installation device for installing a valve shaft and a valve plate of a butterfly valve comprises a strip-shaped workbench 9, wherein a valve body to be installed is placed in the upper end face of the workbench, a main hydraulic cylinder 1 is installed at the front end of the workbench, a piston rod 2 of the main hydraulic cylinder is arranged facing the workbench, and an impact head 3 is installed at the end part of a piston rod of the main hydraulic cylinder. The end parts of piston rods of the two vertical hydraulic cylinders are respectively provided with a lower pressure head 11.
In this embodiment, a sliding groove 7 is formed inwards on each of the two lateral sides of the workbench, a set of pulleys 6 is mounted in the end faces of the two sides of the door-shaped frame on the same side as the sliding groove, each pulley is slidably embedded in the sliding groove on the same side, and the door-shaped frame can reciprocate along the longitudinal direction of the workbench through the pulleys.
In this embodiment, a cross beam 10 is integrally installed at the upper end of the door-shaped frame along the horizontal direction, and the vertical hydraulic cylinders are symmetrically installed on the left side and the right side of the cross beam.
The use process of the invention is as follows:
