Description

Technical Field

[0001] This utility model relates to the field of diaphragm valve technology, and in particular to a diaphragm valve constant torque installation machine. Background Technology

[0002] A diaphragm valve is a type of valve with a special structure and wide range of applications. It uses an elastic diaphragm as an opening and closing element to isolate and control fluids.

[0003] The diaphragm valve has bolts around its perimeter that need to be twisted to secure the outer shell of the diaphragm valve. Four sets of twisting devices are synchronously and vertically inserted into the bolts. The twisting devices are driven by a servo motor to rotate the sleeve on the output end, thus synchronously twisting the four sets of bolts on the diaphragm valve. Because diaphragm valves have different specifications, the bolt spacing around different specifications is not the same. Traditionally, the spacing of the four sets of twisting devices is fixed. When dealing with the next batch of diaphragm valves with different specifications, it is necessary to replace the devices with those that meet the specifications of the diaphragm valves before operation, resulting in excessive equipment occupying factory space. Utility Model Content

[0004] The purpose of this invention is to provide a diaphragm valve constant torque installation machine, which can solve the problems mentioned in the background art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a diaphragm valve constant torque installation machine, comprising: an installation machine body, a horizontal moving component, and a linkage position adjustment component. The installation machine body includes a worktable, a rotary valve fixing mechanism, a lifting mechanism, and a torsion mechanism. The horizontal moving component is disposed on one side above the worktable, and the linkage position adjustment component is disposed above the lifting mechanism.

[0006] By adopting the above technical solution, the position of the torsion mechanism can be adjusted according to the different specifications of diaphragm valves.

[0007] A further feature of this invention is that a rotary valve fixing mechanism is provided on one side above the workbench. The rotary valve fixing mechanism consists of a fixing plate on the output end of a small motor. An area for placing and positioning the diaphragm valve is provided around the fixing plate of the rotary valve fixing mechanism. The lifting mechanism is located directly above the horizontal moving component. The torsion mechanism is located on the linkage position adjustment component. There are four sets of torsion mechanisms. Each torsion mechanism consists of a rotatable sleeve on the output end of a servo motor.

[0008] By adopting the above technical solution, it is possible to simultaneously twist the bolts around the diaphragm valve.

[0009] A further feature of this invention is that the horizontal moving assembly includes a slide rail horizontally welded to the outer wall of one side above the worktable, a slider horizontally slidably mounted on the slide rail, a first cylinder horizontally mounted on the outer wall of the back of the worktable, a connecting plate mounted on the output end of the first cylinder, and the connecting plate connected to the slider above.

[0010] By adopting the above technical solution, it is possible to provide a structure on the slider that can achieve horizontal displacement.

[0011] A further feature of this invention is that the lifting mechanism includes a guide frame vertically welded above the slider, a second cylinder vertically mounted on the top outer wall of the guide frame, and a fixing plate vertically slidably mounted on the guide frame, the fixing plate being connected to the bottom output end of the second cylinder.

[0012] By adopting the above technical solution, it is possible to provide a fixed plate and a structure on the fixed plate with a vertical position change.

[0013] A further feature of this invention is as follows: the linkage position adjustment assembly includes a cross-shaped groove on a fixed plate, with four sets of mounting slides horizontally slidable around the inside of the cross-shaped groove. Each set of mounting slides has a torsion mechanism. Cross-shaped fixing blocks are spaced apart above the fixed plate. Each cross-shaped fixing block has slotted holes around its perimeter and an octagonal hole at its center. Threaded screws are rotatably installed within each of the four slotted holes of the cross-shaped fixing block. A drive motor is positioned at the center above the cross-shaped fixing block. A first bevel gear is mounted on the bottom output end of the drive motor via a rotating shaft. A second bevel gear is mounted at one end of each set of threaded screws, and the four sets of second bevel gears are located inside the octagonal holes of the cross-shaped fixing blocks. The first bevel gear meshes with the second bevel gears located around its perimeter directly below the first bevel gear. A connecting post is welded to the top outer wall of the mounting slide, and a threaded hole is provided at the top of the connecting post. The connecting post is threaded onto the threaded screw through the threaded hole.

[0014] By adopting the above technical solution, it is possible to provide four sets of torsion mechanisms to change position simultaneously.

[0015] The beneficial effects of this utility model are as follows: By setting up a horizontal moving component and a linkage position adjustment component, the linkage position adjustment component can synchronously adjust the spacing between the four sets of torsion mechanisms installed on the linkage position adjustment component according to the specifications of the diaphragm valve. Thus, when dealing with diaphragm valves of different specifications, only one device is needed to perform the torsion operation of the diaphragm valve, effectively reducing the area occupied by the equipment in the factory. Furthermore, by driving the linkage position adjustment component to generate displacement through the horizontal moving component, the position of the torsion mechanism after the spacing is changed can be adjusted, so that the center point between the four sets of torsion mechanisms can be aligned with the middle position of the diaphragm valve, improving the accuracy of the contact between the torsion mechanism and the diaphragm valve.

[0020] Reference Figure 1-4 A diaphragm valve constant torque installation machine includes: an installation machine body, a horizontal moving component 3 and a linkage position adjustment component 6. The installation machine body includes a worktable 1, a rotary valve fixing mechanism 2, a lifting mechanism 4 and a torsion mechanism 5. The horizontal moving component 3 is disposed on one side above the worktable 1, and the linkage position adjustment component 6 is disposed above the lifting mechanism 4.

[0021] A rotary valve fixing mechanism 2 is provided on one side above the workbench 1. The rotary valve fixing mechanism 2 consists of a fixed plate on the output end driven by a small motor. The fixed plate of the rotary valve fixing mechanism 2 has an area around it for placing and positioning the diaphragm valve. The lifting mechanism 4 is located directly above the horizontal moving component 3. The torsion mechanism 5 is located on the linkage position adjustment component 6. There are four sets of torsion mechanisms 5. The torsion mechanism 5 consists of a rotatable sleeve on the output end driven by a servo motor.

[0022] The horizontal moving component 3 includes a slide rail 301 horizontally welded to the outer wall of one side above the worktable 1, a slider 302 horizontally slidably mounted on the slide rail 301, a first cylinder 303 horizontally mounted on the outer wall of the back of the worktable 1, and a connecting plate 304 mounted on the output end of the first cylinder 303, which is connected to the slider 302 above.

[0023] The lifting mechanism 4 includes a guide frame 401 vertically welded above the slider 302, a second cylinder 402 vertically mounted on the top outer wall of the guide frame 401, and a fixing plate 403 vertically slidably mounted on the guide frame 401. The fixing plate 403 is connected to the bottom output end of the second cylinder 402.

[0024] The linkage position adjustment assembly 6 includes a cross-shaped slide groove 601 formed on the fixed plate 403. Four sets of mounting slide plates 602 are horizontally slidable around the inside of the cross-shaped slide groove 601, and each set of mounting slide plates 602 is equipped with a torsion mechanism 5. Cross-shaped fixing blocks 603 are spaced apart directly above the fixed plate 403. Each cross-shaped fixing block 603 has strip-shaped holes around its perimeter and an octagonal hole in its center. Threaded screws 604 are rotatably installed in each of the four sets of strip-shaped holes in the cross-shaped fixing blocks 603. The drive motor 605 is located in the center of the upper part. A first bevel gear 606 is installed on the bottom output end of the drive motor 605 via a rotating shaft. A second bevel gear 607 is installed at one end of each set of threaded screws 604. The four sets of second bevel gears 607 are installed inside the octagonal holes of the cross-shaped fixing block 603. The first bevel gear 606 meshes with the second bevel gears 607 located around the bottom of the first bevel gear 606. The bottom end is welded to the connecting post 608 on the top outer wall of the mounting slide plate 602. The top end of the connecting post 608 has a threaded hole. The connecting post 608 is threaded onto the threaded screw 604 through the threaded hole.

[0025] In this invention, the diaphragm valve is placed on the rotary valve fixing mechanism 2 above the workbench 1. At this time, the positions of the four sets of torsion mechanisms 5 are adjusted according to the specifications of the diaphragm valve. The positions of the four sets of torsion mechanisms 5 can be quickly adjusted by the linkage position adjustment component 6. The horizontal movement component 3 can make the center position of the four sets of torsion mechanisms 5 aligned with the bolts around the diaphragm valve directly below. At this time, the lifting mechanism 4 is activated to drive the torsion mechanism 5 to move vertically downward. Through the contact between the torsion mechanism 5 and the bolts of the diaphragm valve, the bolts around the diaphragm valve are quickly and synchronously torsioned.

[0026] Start the drive motor 605, which drives the first bevel gear 606 connected to the output shaft to rotate. Because the first bevel gear 606 meshes with the second bevel gear 607 of the four sets of threaded screws 604 around the bottom, it synchronously drives the four sets of threaded screws 604 to rotate around the inside of the cross-shaped fixing block 603. Because the threaded screws 604 are threadedly connected to the connecting post 608, the connecting post 608 can change its position inside the cross-shaped fixing block 603. The bottom end of the connecting post 608 is connected to the mounting slide plate 602. At this time, the torsion mechanism 5 on the mounting slide plate 602 can synchronously change its position inside the cross-shaped groove 601 of the fixing plate 403.

[0027] After the four sets of torsion mechanisms 5 have completed their position adjustments, the first cylinder 303 is activated. The connecting plate 304 at the output end of the first cylinder 303 is connected to the slider 302, thereby enabling the slider 302 to move horizontally and stably on the slide rail 301. At this time, the torsion mechanism 5 above the slider 302 is aligned with the diaphragm valve bolt directly below. By activating the second cylinder 402, the second cylinder 402 will drive the fixed plate 403 to move vertically downward on the guide frame 401, so that the torsion mechanism 5 on the fixed plate 403 can contact the diaphragm valve bolt to perform torsion work.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
