The limiting component comprises a first symmetrically connected to the mounting frame 112. The cylinder 112 and the first baffle 115 connected to the first cylinder 112, the pressure-maintaining box 13 is connected to the lifting device 13 through the through hole 1111, the first cylinder 112 drives the first baffle 115 to move in the direction of the through hole 1111, the lifting device 13 rises and drives the pressure-maintaining box 13 to abut against the lower part of the first baffle 115, the limiting device 11 is used to limit the pressure-maintaining box 13, the lifting device 13 is used to place the pressure-maintaining box 13 and to drive the pressure-maintaining box 13 to squeeze the limiting device 11, Thus, the pressure-maintaining box 13 is fixed.

When the pressure-maintaining box 13 is located at the lifting device 13, the lifting device 13 is lowered a certain distance, the limit assembly is started, and the first cylinder 112 drives the first baffle 115 to move toward the direction of the through hole 1111, so that the first baffle 115 15 is located in the through hole 1111, the jacking device 13 rises again and drives the pressure keeping box 13 to rise. When the pressure keeping box 13 abuts against the first baffle 115, the jacking device 13 stops moving, thereby fixing the pressure keeping box 13. When the meter head is assembled, the first cylinder 112 drives the first baffle 115 to be recovered, and the jacking device 13 descends and drives the pressure keeping box 13 with the assembled meter head to descend, thereby saving the time of the robot arm clamping the pressure keeping box 13 and effectively improving the assembly efficiency.

[0038] A first fixing block 1112 is symmetrically provided on the top of the mounting frame 111, and the first cylinder 112 is respectively connected to the first fixing block 1112, the first fixing block 1112 is fixed on the mounting frame 111, and the first cylinder 112 is fixed on the first fixing block 1112, thereby facilitating the first cylinder 112 to be fixed on the top of the mounting frame 111.

[0039] The first baffle 115 is L-shaped, and the mounting frame 111 is further provided with a first through slot 1113 located below the first fixed block 1112. The first baffle 115 can be slidably connected in the first through slot 1113. The L-shaped first baffle 115 is conveniently connected to the first cylinder 112, so that the first cylinder 112 can drive the first baffle 115 to move. The first through slot 1113 is located below the first fixed block 1112, and the first fixed block 1112 can also limit the first baffle 115 to prevent the first baffle 115 from warping up.

[0040] Please refer to Figure 5 , Figure 5 This is a three-dimensional diagram of the second cylinder of the limiting mechanism of the pressure-keeping box of the utility model. The limiting assembly also includes a second cylinder 113 symmetrically connected to the mounting frame 111 and a second baffle 116 connected to the second cylinder 113. The second cylinder 113 is adjacent to the first cylinder 112. The second cylinder 113 is used to drive the second baffle 116 to extend into the first through hole 1111. The second baffle 116 has the same function as the first baffle 115. Since the second cylinder 113 is adjacent to the first cylinder 112 on the mounting frame 111, and the second cylinder 113 is also symmetrically arranged on the mounting frame 111, the first cylinder 112 and the second cylinder 113 simultaneously limit the four sides of the pressure-keeping box 13, thereby ensuring the flatness of the pressure-keeping box 13 and preventing defects in the assembled meter head.

[0041] The mounting frame 111 is also provided with a second fixed block 1115 which is symmetrically connected to the inner side of the top of the mounting frame 111. The second cylinder 113 is connected to the second fixed block 1115. The second cylinder 113 is connected to the top of the mounting frame 111 through the second fixed block 1115, so that the second cylinder 113 can drive the second baffle 116 to extend and retract into the through hole 1111.

[0042] The second baffle 116 is in an inverted L shape. A first limiting block 1151 is further provided on the side of the second baffle 116 that is in contact with the mounting frame 111. The mounting frame 111 is further provided with a first groove 1116 at a position opposite to the first limiting block 1151, a second through groove 1117 located in the first groove 1116 and matching with the first limiting block 1151, and a third fixing block 1118 fixed in the first groove 1116. The first limiting block 1151 is located in the second through groove 1117, and the third fixing block 1118 is provided with a third through groove 1118 that matches with the second baffle 116. Slot 1119, a limiting slot is set at the position where the pressure keeping box 13 is relative to the second baffle 116, and the second baffle 116 is connected to the third through slot 1119 in the third fixing block 1118. The third through slot 1119 is used to prevent the second baffle 116 from tilting up, and the limiting block is located in the second through slot 1117. The second through slot 1117 is used to limit the second baffle 116 to prevent the second baffle 116 from shaking or deviating from its position during movement. After the pressure keeping box 111 rises, it is clamped in the limiting slot of the pressure keeping box 111, thereby further preventing the pressure keeping box 111 from shaking.

[0043] A fourth through slot 1114 is also provided in the first through slot 1113, and a second limit block 1161 opposite to the fourth through slot 1114 is provided at a position opposite to the first baffle 115 and the fourth through slot 1114. The second limit block 1161 is located in the fourth through slot 1114, and the fourth through slot 1114 is used to limit the second limit block 1161 of the first baffle 115. During the movement, the first baffle 115 is limited by the second limit block 1161 to prevent the first baffle 115 from shaking or position shifting during the movement.

[0044] Please refer to Figure 6 and Figure 7 , Figure 6 This is a three-dimensional diagram of the lifting device of the limiting mechanism of the pressure-maintaining box of the utility model. Figure 7 for Figure 6 In the partial enlarged view of part A in the middle, the lifting device 13 includes a third cylinder 121 and a placement component 122 connected to the third cylinder 121 for placing the pressure-maintaining box 13. The third cylinder 121 is used to drive the placement component 122 to rise or fall. The placement component 122 includes a fixed plate 1221 fixedly connected to the third cylinder 121, a placement plate 1222 elastically connected to the fixed plate 1221, and a plurality of elastic members 1224 connected between the fixed plate 1221 and the placement plate 1222. The placement component 122 also includes a symmetrical guide column 1223 fixed to the fixed plate 1221. The placement plate 1222 can be raised and lowered and connected to the guide column 1223. The third cylinder 121 drives the fixed plate 1221 to move upward or downward. 221 rises and falls, since the placing plate 1222 is connected to the fixed plate 1221 through the guide column 1223, and an elastic member 1224 is also provided between the fixed plate 1221 and the placing plate 1222, when the pressure keeping box 13 is located on the placing plate 1222, the third cylinder 121 drives the fixed plate 1221 to rise, and the fixed plate 1221 drives the placing plate 1222 to rise, and the pressure keeping box 13 follows the placing plate 1222 to rise, and when the pressure keeping box 13 is in contact with the first baffle 115 and the second baffle 116, the elastic member 1224 can adaptively adjust the degree of contact of the pressure keeping box 13 on the first baffle 115 and the second baffle 116, so that the pressure keeping box 13 can be smoothly in contact with the first baffle 115 and the second baffle 116.

[0045] In this embodiment, the elastic member 1224 is a spring, but is not limited to using only a spring.

[0046] The mounting frame 111 is also provided with a reflecting optical fiber 114 symmetrically connected to the top of the mounting frame 111 for sensing the height of the pressure-maintaining box 13. The reflecting optical fiber 114 is used to find the height position of the pressure-maintaining box 13. When the reflecting optical fiber 114 senses the height position of the pressure-maintaining box 13, the meter head can be assembled, making the assembly accuracy of the meter head more accurate.

[0047] Working principle:

[0048] When assembling the meter head, first, the third cylinder 121 drives the fixed plate 1221 to rise, and the fixed plate 1221 drives the placement plate 1222 to rise, and the pressure-maintaining box 13 is placed on the placement plate 1222. The third cylinder 121 drives the fixed plate 1221 to descend, so that the pressure-maintaining box 13 is away from the through hole 1111. When the pressure-maintaining box 13 is away from the through hole 1111, the first cylinder 112 drives the first baffle 115 to move toward the through hole 1111. At the same time, , the second cylinder 113 also drives the second baffle 116 to move toward the through hole 1111. Since the first cylinder 112 and the second cylinder 113 are symmetrically arranged on the mounting frame 111, and the first cylinder 112 is adjacent to the second cylinder 113, the first baffle 115 and the second baffle 116 can limit the four sides of the pressure box 13. When the first baffle 115 and the second baffle 116 are located in the through hole 1111, the third cylinder 121 drives the fixing plate 116 to move. 221 rises, and when the pressure keeping box 13 is in contact with the first baffle 115 or the second baffle 116, the third cylinder 121 continues to drive the fixed plate 1221 to rise. Due to the action of the elastic member 1224, the elastic member 1224 can well adjust the flatness of the pressure keeping box 13 and the first baffle 115 and the second baffle 116 to ensure the accuracy of the header assembly. When the pressure keeping box 13 and the first baffle 115 and the second baffle 116 have adjusted the flatness, the optical fiber 114 senses it and the third cylinder 121 stops rising. When the header assembly is completed, the first cylinder 112 drives the first baffle 115 to retract and the second cylinder 113 starts the baffle retraction to facilitate the placement of the next pressure keeping box 13. The third cylinder 121 descends, reserving space for the next pressure keeping box 13, so that there is no need to wait for the robot to clamp and remove the assembled pressure keeping box 13, which saves the time for the robot to clamp the pressure keeping box 13 and effectively improves the assembly efficiency.

[0049] The limiting mechanism of the pressure-keeping box of this preferred embodiment is through extending the pressure-keeping box into the through hole and placing it in the jacking device, the first cylinder drives the first baffle to extend into the through hole, the jacking device drives the pressure-keeping box to rise and squeezes the first baffle, so that the pressure-keeping box and the first baffle are in contact with each other, which is convenient for assembly. When the assembly is completed, the jacking device descends, and the first cylinder drives the first baffle to retract, thereby facilitating the next pressure-keeping box to be extended from the through hole and placed on the jacking device. There is no need to wait for the robot to clamp and move out the assembled pressure-keeping box, which saves the time of the robot clamping the pressure-keeping box and effectively improves the efficiency of assembly.

[0050] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. A person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined by the claims.
