DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-3The top of the fixing column 3 is a truncated cone shaped structure, and the fixing column 3 is a hollow structure. The top of the fixing column 3 is a truncated cone shaped structure. The fixing column 3 is provided with a fixing ring 14 for placing the fixing rod. The fixing column 3 is also provided with a guide cover 5, and the guide cover 5 is adapted to the slot 4. The opening at the bottom end of the guide cover 5 is adapted to the size of the fixing ring 14, so that the guide cover 5 can pass through the fixing ring 14 and be received in the slot 4. Under the action of the guide cover 5, the stopper rod will gradually move toward the bottom position of the guide cover 5 during the downward movement, that is, the bottom end of the stopper rod gradually contacts with the top end of the fixing column 3. In this way, the stopper rod can be quickly positioned and the fixing efficiency can be improved. The mounting frame 2 is provided with a moving component for moving the guide cover 5.

[0024] Reference Figure 1 and Figure 2 The moving component includes a slide groove 7 opened on the inner side of the mounting frame 2, a slide rod 9 is fixedly connected in the slide groove 7, a fixed rod 6 is slidably sleeved on the slide rod 9, the fixed rod 6 is fixed to the guide cover 5, the bottom of the fixed rod 6 and the inner bottom surface of the slide groove 7 are jointly fixedly connected with an air bag 8, an electric telescopic rod 10 and a control box 11 are fixed on the inner side of the mounting frame 2, a sliding plug 12 is slidably connected inside the control box 11, the upper surface of the sliding plug 12 is fixed to the telescopic end of the electric telescopic rod 10, a connecting pipe 13 is connected to the top of the side wall of the control box 11, and the connecting pipe 13 is connected to the air bag 8. When the stopper rod is processed, the guide cover 5 can be received in the slot 4, so as to prevent the guide cover 5 from blocking the stopper rod.

[0025] Reference Figure 1-3The workbench 1 is also provided with a fixing assembly for fixing the stopper rod, and the fixing assembly includes a plurality of fixing openings 17 opened on the side wall of the fixing column 3, and the inner side of the fixing column 3 is fixedly connected with a connecting frame 15 corresponding to the fixing opening 17, and the side wall of the connecting frame 15 is fixedly connected with an airbag 2 16, and the airbag 2 16 passes through the fixing opening 17. The connecting frame 15 is a U-shaped structure, and the inner side of the connecting frame 15 is on the same horizontal line as the fixing opening 17. The connecting frame 15 guides the airbag 2 16, so that the airbag 2 16 can pass through the fixing opening 17 after expansion. The bottom end of the side wall of the control box 11 is connected with a connecting pipe 2 18, and the connecting pipe 2 18 is respectively connected with all the airbags 2 16, and the control box 1 1 is provided with an electrorheological fluid 19, and the electrorheological fluid 19 is located at the bottom of the sliding plug 12. The electrorheological fluid 19 is a suspension, which is in liquid state under normal conditions and can change from liquid to solid state under the action of an electric field. Its specific working principle and internal structure are all prior art and will not be described in detail here. Under the action of the airbag 16 and the electrorheological fluid 19, the device can fit the inner side of the plug rod more closely, and compared with the traditional threaded rod fixing method, the contact area between the device and the plug rod is larger, which can ensure the stability of the plug rod position. The side wall of the airbag 16 away from the connecting frame 15 is provided with anti-slip grooves, which can increase the friction between the airbag 16 and the inner side of the plug rod and improve the stability of the plug rod fixing.

[0026] The specific working principle of the utility model is as follows:

[0027] When it is necessary to fix the stopper rod, first place the bottom end of the stopper rod in the guide cover 5, then move the stopper rod downward. Under the guidance of the guide cover 5, the bottom end of the stopper rod will move downward and toward the center of the circle at the bottom end of the guide cover 5. In this way, when the bottom end of the stopper rod moves to the bottom position of the guide cover 5, the stopper rod just corresponds to the fixing column 3. In this way, the stopper rod is continued to be moved downward, and the stopper rod can be placed on the fixing column 3. When the stopper rod is completely placed on the fixing column 3, the bottom end of the stopper rod is placed on the fixing ring 14. Then the staff starts the electric telescopic rod 10, so that the telescopic end of the electric telescopic rod 10 extends and then presses the sliding plug 12 downward, so that Negative pressure is generated above the slide plug 12, and the air in the airbag 8 is sucked into the control box 11. The contraction of the airbag 8 drives the fixed rod 6 to move down along the slide rod 9, so that the guide cover 5 can be moved into the slot 4, so that the guide cover 5 can be stored during the processing, and the guide cover 5 can be prevented from blocking the stopper rod. In this way, under the action of the guide cover 5, the staff does not need to manually adjust the stopper rod and the fixed column 3 to a coaxial position, so as to achieve the purpose of rapid positioning of the stopper rod, reduce the labor of the staff, and improve the processing efficiency, especially for the stopper rod that needs to be transported by a lifting device, and can also reduce safety hazards;

[0028] Furthermore, in the above process, the downward movement of the sliding plug 12 can squeeze the electrorheological fluid 19 into the airbag 16, and the airbag 16 expands and then extends out of the fixing port 17 and abuts against the inner side of the plug rod. Then, electricity is applied to the electrorheological fluid 19. Under the action of the electric field, the electrorheological fluid 19 changes from liquid to solid, thereby fixing the plug rod. The inside of the unprocessed and polished plug rod is uneven. Under the action of the electrorheological fluid 19 and the airbag 16, the device can fit the inner side of the plug rod, which increases the contact area between the two and ensures the stability of the fixation.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
