Technical Field

[0001] The utility model belongs to the technical field of valve assembly, and in particular relates to a valve fixing and assembling device. Background Art

[0002] A valve is a device used to control the direction, pressure and flow of a fluid in a fluid system. A valve is a device that allows the medium (liquid, gas, powder) in pipes and equipment to flow or stop and control its flow. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. A valve is a control component in a pipeline fluid delivery system. It is used to change the passage section and the flow direction of the medium and has the functions of diversion, cut-off, throttling, non-return, diversion or overflow pressure relief. Since there are many parts of a valve, it is necessary to assemble the various parts of the valve.

[0003] In the prior art, most of the valves are assembled manually. During the assembly process, the components are mainly placed in the lower part of the valve body, and then the upper part of the valve body is aligned and engaged with the lower part of the valve body, and finally the upper part of the valve body is connected with the lower part of the valve body by bolts, and then the bolts are installed and tightened. When the valve is assembled manually, since the valve is not fixed, the staff needs to tighten the bolts of the valve while fixing the valve, which is time-consuming and labor-intensive and is not conducive to the standardized production of valves.

[0029] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0030] like Figure 1-4 As shown, a valve fixing and assembling device comprises a workbench 1, a connecting platform 11 is provided on the upper side of the workbench 1, a fixing mechanism 12 for fixing the valve is rotatably connected on the upper side of the connecting platform 11, a positioning mechanism 13 for positioning the fixing mechanism 12 is provided between the connecting platform 11 and the fixing mechanism 12, and a tightening mechanism 14 for tightening bolts is provided on the upper side of the workbench 1;

[0031] The fixing mechanism 12 includes a square plate 121 with a circular groove in the middle, two connecting seats 122, an AC motor 123, a bidirectional lead screw 124, two fixing members 125, a limit strip 126, a first telescopic cylinder 127 and a fixing plate 128. The square plate 121 is rotatably connected to the connecting platform 11, the rotating axis of the square plate 121 is the center of the square plate 121, the two connecting seats 122 are located on one side of the square plate 121, the bidirectional lead screw 124 and the limit strip 126 are both assembled and connected between the two connecting seats 122, the output shaft of the AC motor 123 is assembled and connected to the bidirectional lead screw 124, the two fixing members 125 are both threadedly connected to the bidirectional lead screw 124 and symmetrically fixed on both sides of the bidirectional lead screw 124, the fixing member 125 is slidably connected to the groove provided in the limit strip 126, the first telescopic cylinder 127 is located on the opposite side of the bidirectional lead screw 124, and the fixing plate 128 is assembled and connected to the output end of the first telescopic cylinder 127.

[0032] By adopting the technical solution of this embodiment, the fixing mechanism 12 is rotatably connected to the connecting platform 11. When the fixing mechanism 12 completes fixing the valve, the valve can be rotated by rotating the fixing mechanism 12, so as to facilitate the staff to assemble the valve. When the tightening mechanism 14 tightens the bolts connecting the valve, the fixing mechanism 12 is rotated to rotate the valve, which can facilitate the tightening mechanism 14 to tighten the bolts installed at the four corners of the valve. The positioning mechanism 13 is used to fix the fixing mechanism 12 that is rotated to a desired angle; the bidirectional lead screw 124 is used to control the fixing member 125 to move toward the middle at the same time to center and fix the valve, the limit strip 126 is used to prevent the fixing member 125 from rotating, and the first telescopic cylinder 127 is used to control the fixing plate 128 to fix the valve; it should be noted that the fixing member 125 and the fixing plate 128 can contact the lower and upper parts of the valve at the same time, so that the upper part of the valve is aligned with the lower part; when assembling the valve, the staff first places the lower part of the valve in the circular groove opened in the square plate 121, and then places the parts in the lower part of the valve, and then places the upper part of the valve above the lower part of the valve, and controls the AC motor 123 to fix the two fixing parts 125 to the opposite sides of the valve, and at the same time controls the first telescopic cylinder 127 to fix the fixing plate 128 to one of the other two sides of the valve, and then places the bolts in the valve, controls the tightening mechanism 14 to tighten the bolts, and when one bolt is tightened, rotates the square plate 121 to align the other bolt with the tightening mechanism 14, and then fixes the square plate 121 through the positioning mechanism 13, and the tightening mechanism 14 tightens the bolts.

[0033] Reference Figure 3 : The two fixing members 125 are fixedly connected to a positioning plate 129 parallel to the fixing plate 128.

[0034] In this embodiment, the positioning plate 129 is used to cooperate with the fixing plate 125 to fix the other two opposite surfaces of the valve.

[0035] Reference Figure 2 The tightening mechanism 14 includes a connecting frame 141, a second telescopic cylinder 142 and an electric wrench 143. The connecting frame 141 is fixedly connected to the workbench 1, and the second telescopic cylinder 142 is assembled and connected between the electric wrench 143 and the connecting frame 141. The electric wrench 143 is located directly above the bolt.

[0036] In this embodiment, when tightening the bolt, the second telescopic cylinder 142 controls the electric wrench 143 to descend so that the electric wrench 143 contacts the bolt, and then controls the electric wrench 143 to tighten the bolt. The electric wrench can keep the tightening force of the bolt within a reasonable range.

[0037] The connecting platform 11 is rotatably connected to the working platform 1 , and a driving mechanism for controlling the rotation of the connecting platform 11 is provided at the center position of the lower side of the working platform 1 .

[0038] In this embodiment, the connecting platform 11 can rotate. When assembling parts, the connecting platform 11 can rotate so that the tightening mechanism 14 is not located directly above the square plate 121, thereby better assembling the valve parts.

[0039] The driving mechanism is a servo motor.

[0040] In this embodiment, the servo motor 2 is used to control the connection platform 11 to rotate, and the connection platform 11 can be controlled by a program to stop rotating after rotating a certain angle.

[0041] Reference Figure 2-3 The connecting platform 11 is provided with a square groove 111 , and the square groove 111 is located at the center of the square plate 121 .

[0042] In this embodiment, the valve is placed in the square groove 111 , and the bottom of the valve is in contact with the workbench 1 .

[0043] Reference Figure 3 The workbench 1 is provided with a material discharge trough 112, which is located on the opposite side of the tightening mechanism 14. When the connecting platform 11 rotates a certain angle, the center of the square groove 111 coincides with the center of the material discharge trough 112, and the size of the material discharge trough 112 is larger than the square groove 111.

[0044] In this embodiment, when the valve is assembled, the servo motor 2 is used to control the connection platform 11 to rotate so that the center of the square groove 111 is aligned with the center of the discharge chute 112, and the fixing mechanism 12 releases the fixation of the valve, and then the valve can fall into the conveying mechanism through the discharge chute 112. It should be noted that the conveying mechanism is used to transport the valve to a designated area. Since the main problem solved by this device is to assemble the valve, the conveying mechanism is not explained.

[0045] Reference Figure 3-4 The positioning mechanism 13 includes a first positioning pin 131 and a latch seat 132. The four sides of the square plate 121 are provided with latch holes. The square plate 121 is located on one side of the latch seat 132. The first positioning pin 131 is plugged with the latch hole and the latch seat 132. The first positioning pin 131 is provided with two round holes 133 in sequence. The upper side of the latch seat 132 is provided with a positioning hole 134. The positioning hole 134 is slidably connected with a second positioning pin 135. The other side of the latch seat 132 is provided with a positioning seat 136. When the second positioning pin 135 is plugged with the round hole 133 near the square plate, one end of the first positioning pin 131 is separated from the square plate 121, and the other end of the first positioning pin 131 is abutted against the positioning seat 136. .

[0046] In this embodiment, after the electric wrench 143 tightens one bolt, the second positioning pin 135 moves upward, then removes the first positioning pin 131 from the pin hole, and then rotates the square plate 121 90 degrees to align the other bolt with the electric wrench 143. Then, the first positioning pin 131 is inserted into the pin hole to prevent the square plate 121 from rotating, and the second pin hole 135 is inserted into the positioning hole 134 and the round hole 133 to prevent the first positioning pin 131 from moving.

[0047] Working principle: first, place the lower part of the valve in the square groove 111 of the connecting platform 11, then place the parts in the lower part of the valve, then engage the upper part of the valve with the lower part of the valve, control the AC motor 123 to rotate, so that the fixing part 125 fixes the opposite sides of the valve, and at the same time, the positioning plate 129 fixes the position of one side of the valve, and then control the first telescopic cylinder 127 to fix the fixing plate 128 to the other side of the valve, so that the valve is located at the center of the square plate 121, and at the same time, the electric wrench 143 is aligned with a bolt of the connecting wrench, and then control the second telescopic cylinder 127 to descend, so that the electric wrench 143 contacts the bolt and tightens the bolt. Prior to this, the first positioning pin 131 has positioned the square plate 121 to prevent the square plate 121 from rotating, and a bolt After the bolt is tightened, first take out the second positioning pin 135, then take out the first positioning pin 131, plug the first positioning pin 131 into the inner circular hole 133, and at the same time, the end of the first positioning pin 133 contacts the positioning seat 136, and the first positioning pin 133 is positioned, and then the side plate 121 can be rotated. The side plate 121 is rotated 90 degrees to align the remaining bolts of the valve with the electric wrench 143, and then the side plate 121 is positioned by the first positioning pin 131 and the second positioning pin 135, and then the electric wrench 143 tightens the bolts. After the bolts are tightened, rotate the connecting platform to align the square groove 111 with the discharge chute 112, and then cancel the fixation of the valve by the fixing piece 125 and the fixing plate 128, and the valve falls into the conveying mechanism through the discharge chute 112.

[0048] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention.
