Specific embodiments
[0011] Refer to Figure 1 Figure 2 Figure 3 Figure 4The described positioning and fixing device for the welding end of a heat insulation cover pipe is characterized in that: it includes a fixed base 1, and a sliding device 2 is provided in the middle of the upper surface of the fixed base 1. A connecting bracket 3 is connected to the middle of the front edge of the upper surface of the sliding device 2. An exhaust pipe 4 is arranged in the middle of the front surface of the connecting bracket 3. A positioning support block 5 is connected to the upper right corner of the front surface of the connecting bracket 3. A pressing device 6 is connected to the middle of the rear surface of the connecting bracket 3. A hand vice 7 is connected to the middle of the rear surface of the pressing device 6. The sliding device 2 includes a bottom plate 2-1, a sliding plate 2-2, a slide rail 2-3 and a pull rod 2-4. The sliding plate 2-2 is arranged in the middle of the upper surface of the bottom plate 2-1. Slide rails 2-3 are symmetrically connected to the left and right middle parts between the sliding plate 2-2 and the bottom plate 2-1. A pull rod 2-4 is connected to the middle of the right side surface of the bottom plate 2-1. The front part of the inner surface of the pull rod 2-4 is connected to the right side surface of the sliding plate 2-2 by a rotating shaft. The connecting bracket 3 includes a front plate 3-1, a through hole 3-2, a support column 3-3 and a rear plate 3-4. A through hole 3-2 is provided in the middle of the front surface of the front plate 3-1. A number of support columns 3-3 are evenly distributed and connected to the periphery of the rear surface of the front plate 3-1. A rear plate 3-4 is connected between the centers of the rear surfaces of each support column 3-3. A through hole 3-2 is provided in the middle of the front surface of the rear plate 3-4. The lower surface of the front plate 3-1 is connected to the upper surface of the sliding plate 2-2. The position of the through hole 3-2 on the front plate 3-1 corresponds to the position of the through hole on the rear plate 3-4. The pressing device 6 includes a cylinder 6-1, a connecting rod 6-2, a cross column 6-3 and a clamping claw 6-4. The connecting rod 6-2 is connected to the center of the front surface of the telescopic end of the cylinder 6-1. The cross column 6-3 is connected to the center of the front surface of the connecting rod 6-2. Clamping claws 6-4 are symmetrically connected to the upper and lower outer surfaces of the cross column 6-3. The cylinder 6-1 is inserted between the front plate 3-1 and the rear plate 3-4. The connecting rod 6-2 penetrates and is inserted into the through hole 3-2 on the front plate 3-1. The clamping claw 6-4 is rotatably connected to the side surface of the front plate 3-1.
[0012] During use, first, the staff places the fixed base 1 on the workbench and fixes it. Then, the staff places the flange end on the exhaust pipe 4 on the front plate 3-1 of the connecting bracket 3. At the same time, the notch on the side surface of the flange on the exhaust pipe 4 is stuck on the positioning support block 5 to position the exhaust pipe 4. Then, the staff starts the cylinder 6-1 on the pressing device 6 to extend the telescopic end. At the same time, the cross column 6-3 is driven forward through the connecting rod 6-2. At the same time, the cross column 6-3 pushes the clamping claw 6-4 to rotate on the side surface of the front plate 3-1 and presses the flange tightly. Finally, the staff holds the pull rod 2-4 on the sliding device 2 to drive the sliding plate 2-2 to slide on the slide rail 2-3. At the same time, the sliding plate 2-2 drives the front plate 3-1 to move forward to press the other end of the exhaust pipe on the fixture.
[0013] When replacing the exhaust pipe, first release the gas in cylinder 6-1. Then, the worker pulls the manual pliers 7. Since cylinder 6-1 is a double-headed cylinder, the telescopic end on cylinder 6-1 retracts. At the same time, it moves backward through the cross column 6-3 and drives the pressure claw 6-4 to rotate on the side surface of the front plate 3-1, causing the pressure claw 6-4 to loosen. Finally, the worker pulls the pull rod 2-4 to slide the slide plate 2-2 backward, and then the exhaust pipe 4 can be removed.
[0014] The function of the manual pliers 7 is to control the extension length of the telescopic column on cylinder 6-1, and the telescopic column can be fixed when cylinder 6-1 is in the gas filling operation.
