detailed description

The present invention will be further described below in conjunction with accompanying drawing.

As shown in Fig. 1, Fig. 2 and Fig. 3, a pneumatic installation tool for an incubator sealing ring includes a body 1, and a hammer 2 is arranged in the body 1, the hammer 2 is in the shape of an inverted T, and the top of the hammer 2 is a The side is provided with an inclined surface, and a fixed splint 6 and a movable splint 7 are arranged on one side of the body 1, the fixed splint 6 is fixedly connected with the body 1, the movable splint 7 and the fixed splint 6 are connected by a connecting piece 11, and the bottom end of the movable splint 7 is connected to the striker The slope of the hammer 2 is in virtual contact, and the top of the movable splint 7 is flush with the top of the body 1; the bottom of the body 1 is provided with a lower end cover 4, which is connected with the bottom end of the body 1 by bolts, and an air inlet is provided on the lower end cover 4 5. A spring 3 is provided on one side of the hammer 2. The upper end of the spring 3 is in virtual contact with the body 1, and the lower end is in virtual contact with the hammer 2.

There is at least one spring 3. After the sealing ring is installed, the spring 3 will give the hammer 2 a downward force to ensure that the hammer 2 returns to the bottom of the body 1 under the action of the spring 3.

The other side of the body 1 is provided with a limit foot installation hole 8, and the limit foot 9 is connected with the limit foot installation hole 8, and a positioning wheel 10 is arranged at one end of the limit foot 9, and the limit wheel 10 will be set when the lower cover sealing ring is installed. When the positioning pin 9 is installed, the positioning wheel 10 is close to the inner wall of the macerator, and the limit pin 9 is close to the lower edge of the macerator, so that the upper end of the body 1 and the inner ring of the sealing ring installation groove are in the same plane, and the positioning pin 9, positioning Wheel 10 is provided with two, can realize positioning to splint 6, and sealing ring location is accurate;

The connecting member 11 is a pin shaft or a bolt, and the precision requirement of the pin shaft is relatively high, and the precision requirement of the screw is relatively low. These two connection methods are relatively simple and convenient for installation and disassembly.

The bottom end of the lower end cover 4 and the body 1 is bolted or clamped, and the bottom end of the lower end cover 4 exceeds the bottom of the body 1 , so that it is easy to disassemble when maintaining the hammer 2 or the body 1 .

Example 1

As shown in Figure 1, when installing the lower sealing ring, install the stop pin 9, the positioning wheel 10 is close to the inner wall of the dipper, and the stop pin 9 is close to the lower edge of the dipper, so that the upper end of the body 1 can be aligned with the dipper. The inner ring of the sealing ring installation groove is on the same plane, and two positioning feet 9 and locating wheels 10 are provided, so that the fixed body 6 can be positioned. When the lower sealing ring is installed, the hammer 2 can return under the action of its own gravity. To the bottom of the body 1, the spring 3 can be removed; the use process: the present invention uses air pressure as the power, press the switch, the hammer 2 rises, and the slope of the hammer 2 gives an outward force to the lower end of the movable splint 7, driving the movable splint The upper end of 7 tightens the sealing ring, so that the distance between the upper end of the body 1 and the movable splint 7 is slightly smaller than the sealing ring installation groove. As the hammer 2 rises, the sealing ring is squeezed into the sealing ring installation groove, and the switch is released. , the hammer 2 returns to the bottom of the body 1 under the action of its own gravity, and at the same time, the movable splint 7 loosens the sealing ring, moves the body 1, and adjusts the installation position.

Example 2

As shown in Figure 3, when installing the sealing ring of the upper cover, the limit pin 9 is removed; the process of use: the present invention uses air pressure as the power, presses the switch, the hammer 2 descends, and the inclined plane of the hammer 2 moves the splint 7 An outward force at the lower end of the movable splint 7 drives the upper end of the movable splint 7 to tighten the sealing ring, so that the distance between the upper end of the body 1 and the movable splint 7 is slightly smaller than the sealing ring installation groove. As the hammer 2 descends, the sealing ring is squeezed into the The sealing ring is installed in the groove, release the switch, the hammer 2 returns to the bottom of the body 1 under the action of the spring 3, and at the same time, the movable splint 7 loosens the sealing ring, moves the body 1, and adjusts the installation position.
