Description

Technical Field

[0001] The invention relates to a clamping device, in particular to an inductor coil clamping device. Background Art

[0002] As an important component of electronic components, inductor coils must undergo multiple clamping operations during the production and processing process. In order to improve efficiency, clamping tools for synchronously clamping multiple groups are produced. However, traditional clamping devices usually require multiple independent cylinders, springs or electric devices to drive each clamp. Although high-precision control can be achieved, there are problems such as complex driving structure, bulky size, and high cost. As shown in a patent for a clamping mechanism of an inductor coil (Announcement No. CN201821611340.8), especially when multiple groups of clamps work together, if each group of clamps requires a separate drive system, it will greatly increase the complexity of the system and the difficulty of maintenance. Summary of the invention

[0003] In order to solve the above technical problems, the purpose of the present invention is to provide an inductor coil clamping device, which only requires one set of driving units to complete the clamping of multiple groups of products under a certain air pressure. Since the multiple groups of products are clamped under the same air pressure, the air pressure in the piston cavity can be ensured to be the same, thereby ensuring that the clamping effect is highly consistent. Even if products of different models and sizes are clamped synchronously, it can be ensured that the pressure applied to the product is the same due to the same air pressure. The same pressure can also reduce the probability of the inductor coil being damaged by mechanical force during the clamping process.

The piston block at one end of the piston rod 42 is arranged in the spring cavity 43, and the piston block at the other end is arranged in the piston cavity 44. The connecting piece 5 is installed on the tooling base plate 1 for conversion, and is connected to the air pressure cavity 3 through a rotating joint 9. When the connecting piece 5 is driven by the driving unit 6 to rotate and communicate with the piston cavity 44, the gas in the air pressure cavity 3 is pressed into the piston cavity 44 to realize the clamping action of the clamping jaw unit 41, and when the pressure in the piston cavity 44 is released, the spring in the spring cavity 43 is used to realize the loosening action of the clamping jaw unit 41 by pressing the piston block.
