Description

Technical Field

[0001] This utility model relates to the field of track air circuit board processing technology, specifically to an L-shaped positioning fixture for a suction cup in track air circuit board processing. Background Technology

[0002] In the machining of track air circuit boards, suction cups are a key component. In the past, without efficient suction devices, securing relatively delicate components like track air circuit boards was a challenge. Mechanical clamps were typically used, but these could easily damage the surface of the air circuit board, which may contain many delicate pipe structures and electronic component mounting areas. The advent of suction cup technology has changed this situation. Suction cups operate using atmospheric pressure. By using a vacuum pump or similar device to extract air from the suction cup, a pressure difference is created inside and outside the cup, thus firmly adhering the track air circuit board. This ensures that the air circuit board is stably fixed to the worktable during machining operations such as cutting, drilling, or surface grinding, without the localized compression and damage that can occur with mechanical clamps.

[0003] Previously, when using suction cups to process pneumatic circuit boards, each board required a dial indicator to straighten its surface. A centering bar was used to determine the center position of each piece. This resulted in a significant waste of time on workpiece straightening and centering, leading to low clamping efficiency, especially in small-batch production where a large amount of time was spent on clamping. Utility Model Content

[0004] The purpose of this utility model is to provide an L-shaped positioning fixture for the suction cup of the track air circuit plate to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an L-shaped positioning fixture for a suction cup in the processing of a track air circuit board, comprising a worktable, with multiple grooves formed on the upper surface of the worktable, a suction cup connected to the upper surface of the worktable, a workpiece air circuit board connected to the upper side of the suction cup, a first movable positioning block and a second movable positioning block connected to one end of the suction cup, a third movable positioning block and a fourth movable positioning block connected to one side of the suction cup, and a first positioning crossbeam connected to the other end of the first movable positioning block and the second movable positioning block.

[0006] Preferably, the first movable positioning block and the second movable positioning block are fixedly connected to a suction cup, and the first positioning beam is fixedly connected to the first movable positioning block and the second movable positioning block.

[0007] Preferably, the lower side of the first positioning beam is connected to the first base and the second base by a fixing screw, and the bottom of the first base and the second base are connected to the slider by a fixing screw, and the slider is inserted into the inner cavity of the groove.

[0008] Preferably, the third movable positioning block is fixedly connected to a suction cup at one end of the second movable positioning block, and the other end is fixedly connected to a second positioning beam.

[0009] Preferably, the third base is threadedly connected to the bottom of the second positioning beam by a fixing screw, and the bottom of the third base is threadedly connected to a slider by a fixing screw, the slider being engaged in the inner cavity of the groove.

[0010] Preferably, the upper side of the suction cup adsorbs the lower side of the workpiece air passage plate, and the workpiece air passage plate is restricted from detaching from the suction cup.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This track pneumatic circuit board processing suction cup L-shaped positioning fixture. The L-shaped fixture can use two mutually perpendicular planes, the first positioning beam and the second positioning beam, to determine the position of the workpiece pneumatic circuit board and the suction cup. The first base, the second base, and the third base can adjust the position of the suction cup and the workpiece pneumatic circuit board through sliders and grooves. The base is fixed by tightening screws. The first positioning beam and the second positioning beam restrict the rotation of the pneumatic circuit board, thereby achieving the purpose of precise positioning.

[0013] 2. This track pneumatic circuit board processing suction cup L-shaped positioning fixture uses a suction cup to adsorb the pneumatic circuit board by generating negative pressure. When the pneumatic system of the fixture is activated, gas is drawn out of the suction cup, making the air pressure inside the suction cup lower than the external atmospheric pressure. According to the principle of pressure difference, the external atmospheric pressure will press the workpiece pneumatic circuit board tightly onto the suction cup, preventing it from shaking and falling off the suction cup during processing, thus achieving the purpose of fixing the workpiece pneumatic circuit board and improving the practicality and safety of the fixture.

[0026] In this embodiment, the suction cup 3 adsorbs the air circuit board by generating negative pressure.

The base is fixed by tightening the screws. The first positioning beam 9 and the second positioning beam 12 restrict the rotation of the air passage plate, thereby achieving the purpose of precise positioning. The suction cup 3 adsorbs the air passage plate by generating negative pressure. When the air passage system of the fixture is started, the gas is drawn out of the suction cup 3, making the air pressure inside the suction cup 3 lower than the external atmospheric pressure. According to the principle of pressure difference, the external atmospheric pressure will press the workpiece air passage plate 4 tightly onto the suction cup 3, preventing it from shaking and falling off the suction cup 3 during processing, thus achieving the purpose of fixing the workpiece air passage plate 4 and improving the practicality and safety of the fixture.
