Description

Technical Field

[0001] The utility model relates to the technical field of bicycle accessories processing, in particular to a punching machine for processing automobile swing arms. Background Art

[0002] The triangular arm refers to the swing arm, which is used for balancing and supporting. When the car is driving on an uneven road, the tire will swing up and down, which is achieved by the swing of the triangular arm. The tire is installed on the axle head, and the axle head is connected to the triangular arm through a ball head.

[0003] The swing arm comprises a swing arm body, a bushing and a ball head assembly. A plug-in hole for the bushing to be plugged in and installed is provided on the swing arm. The bushing is installed on the plug-in hole by stamping.

[0004] At the assembly station, the traditional installation method is usually for personnel to use a plastic hammer to hit and punch the bushing to press it into the socket hole of the swing arm;

[0005] The above method consumes a lot of physical energy, and the force of the hammering is difficult to control, which can easily cause the workpiece to be misaligned during assembly, causing damage to the workpiece, thereby generating waste parts.

[0006] For this reason, we propose a automobile swing arm processing punching machine to solve the existing problems. Utility Model Content

[0007] The utility model aims to solve the problems existing in the background technology and proposes a punching machine for processing automobile swing arms.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a kind of automobile swing arm processing punching machine, including a cylinder, a hammer head and a slide rod, the cylinder body is provided with a slide rod for lifting and lowering, the outer wall of the lower end of the slide rod is provided with a positioning block, the slide rod is movably sleeved with an outer spring and a movable ring, the outer spring is located between the positioning block and the movable ring, and the hammer head is fixed on the movable ring by a mounting nail.

[0009] Preferably, a cover is fixed to the bottom end of the slide rod by bolts, and the diameter of the cover is larger than the diameter of the slide rod;

[0010] The hammer head is provided with a groove matched with the sealing cover, and the sealing cover is located in the groove.

[0011] Preferably, a piston is fixed to the top end of the slide rod, and the piston is slidably mounted inside the cylinder;

[0012] An inner spring is movably sleeved on the slide rod, and the inner spring is located between the bottom end of the inner wall of the cylinder and the lower surface of the piston;

[0013] The original length of the inner spring is greater than the interior depth of the barrel.

[0014] Preferably, the outer walls at the upper and lower ends of the cylinder are symmetrically provided with annular protrusions, and a handle is installed between the two annular protrusions by bolts.

[0015] Preferably, an air inlet pipe is embedded and installed on the upper surface of the cylinder, and an air outlet pipe is connected to the air inlet pipe;

[0016] The ends of the air inlet pipe and the air outlet pipe are both provided with electric control valves.

[0017] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0018] During the use of the automobile swing arm processing punching machine of the utility model, a person can hold the device and make the hammer head face the punching position of the automobile swing arm processing. At this time, the external compressed air is connected through the air intake pipe. Under the action of the air pressure, the piston drives the slide bar downward, so that the hammer head moves downward to perform a punching operation on the automobile swing arm processing position. After the punching is completed, the air intake pipe is disconnected, the air outlet pipe is opened, and the air inside the cylinder is discharged through the air outlet pipe. Then, the piston automatically resets with the hammer head under the elastic force of the inner spring;

[0019] Furthermore, when the hammer head is downwardly punching the workpiece, the hammer head is subjected to force and moves upward relative to the slide bar. At this time, the movable ring upwardly squeezes the outer spring, and the outer spring deforms to absorb the impact force on the hammer head, so that the hammer head is in soft contact with the processing position of the automobile swing arm, which can prevent the hammer head from damaging the workpiece.

[0020] The utility model has a small size and is convenient for personnel to hold in hand, and the force of the hammer head hitting can be accurately controlled by controlling the air intake, thereby saving personnel's physical strength and reducing the productivity of waste parts.
