Description

Engine intake pipe pneumatic clamp

technical field

The utility model relates to a pneumatic clamp for an engine intake pipe.

Background technique

At present, for the intake pipe of a diesel engine, the clamping method of the tooling is to press the inner wall of the nozzle at both ends with a manual pressure plate. Because the parts are slender rods and cast aluminum parts, limited by the mechanical properties of their own materials, they are clamped at both ends. The middle of the rear pipe body is bent and deformed, so that the dimensional tolerance after processing cannot meet the requirements of the drawing, and the manual pressing increases the labor intensity of the workers, and the pressing force is uneven, the product processing accuracy is low, and the product quality is not up to standard.

Contents of the invention

The technical problem to be solved by the utility model is to provide a pneumatic clamp for fixing the intake pipe of the engine, which can improve the machining accuracy of the intake pipe.

In order to solve the above technical problems, the utility model includes a frame whose bottom surface can be fixed on the machine tool and whose top surface can fix the intake pipe of the engine. At least two rotary cylinders are installed on the frame, and the piston rods of the rotary cylinders protrude from the top surface of the frame. And a compression block is connected at the end.

After the above structure is adopted, the engine intake pipe is placed on the top surface of the frame, so that the piston rod of the rotary cylinder extends into the branch pipe, and the piston rod rotates to press the compression block on the pipe wall of the intake pipe, thereby realizing the compression of the intake pipe. This kind of clamping method has a uniform pressing force, so that the intake pipe can meet the processing accuracy requirements after processing, and at the same time reduce the labor intensity of workers and improve production efficiency.

The frame includes a top plate and a bottom plate arranged up and down, the top plate and the bottom plate are connected as a whole through a support plate, and a rotary cylinder is installed between the bottom plate and the top plate.

Described top plate is provided with the locating pin that can insert the bolt hole on the branch pipe of engine intake pipe, and engine intake pipe is positioned with locating pin, is convenient to piston rod stretches in the branch pipe.

The base plate is provided with an opening slot, and the entire pneumatic clamp can be fixed on the machine tool workbench with bolts.

Detailed ways

As shown in Figures 1 to 3, this embodiment is a pneumatic clamp suitable for clamping the intake pipe of a six-cylinder engine. The pneumatic clamp for the intake pipe of the engine includes a frame whose bottom surface can be fixed on the machine tool and whose top surface can fix the intake pipe of the engine. The frame includes a top plate 1 and a bottom plate 2 arranged horizontally up and down. The top plate 1 and the bottom plate 2 are connected as a whole by a plurality of support plates 3 arranged vertically. Ten rotary cylinders 4 are installed on the bottom surface of the top plate 1, and the rotary cylinders 4 are arranged in two rows, with five rows in each row. The arrangement of the rotary cylinders 4 in each row is compatible with the arrangement of the branch pipes 11 of the intake pipe 10 , so that two intake pipes 10 can be fixed at the same time to improve work efficiency. The top plate 1 is provided with a positioning plate 12, and the top plate 1 and the positioning plate 12 are provided with a through hole. The piston rod 5 of the rotary cylinder 4 passes through the through hole and is connected to the end of the piston rod 5, which is perpendicular to the piston rod 5 and extends to one side. Out of the compression block 6, the height of the piston rod 5 extending out of the positioning plate 12 is slightly greater than the length of the branch pipe 11, so that the piston rod 5 extends into the branch pipe 11, and the bottom surface of the compression block 6 can just stick to the wall of the intake pipe 10. close, so as to realize compression, as shown in Figure 3, the two states of the compression block 6.

Positioning pins 8 are respectively arranged on the positioning plate 12 positioned at both ends of the top plate 1, and the positioning pins 8 at both ends can be inserted into the bolt holes 7 of the two branch pipes 11 at the two ends of the engine intake pipe 10. During use, the positioning pins 8 can connect the engine intake pipe 10 Positioning is convenient for the piston rod 5 to extend into the branch pipe 11. Open slots 9 are provided on both sides of the base plate 2 in the length direction, T-shaped slots are provided on the machine tool workbench, and the base plate 2 is fixed on the machine tool workbench by bolts.

The utility model is not limited to this embodiment. During use, the number of rotary cylinders can be reasonably selected according to the number of branch pipes on the intake pipe, and the number of rows of rotary cylinders can also be set according to the needs of on-site work. When in use, the engine intake pipe 10 is positioned by the positioning pin 8. At this time, the reference plane of the intake pipe is in contact with the top surface of the top plate 1, and the piston rod 6 of the rotary cylinder 5 extends into the branch pipe 11, and then drives the rotary cylinder 4, and the piston rod 5 rotates. The pressing block 6 is pressed against the pipe wall of the intake pipe 10, so as to realize the compression of the intake pipe 10. This clamping method has a uniform pressing force, so that the processing accuracy requirements of the intake pipe can be met after processing, and at the same time, the labor intensity of workers can be reduced. ,Increase productivity.
