[0002] The main function of the car heat shield parts is to reduce the transfer of radiant heat flow. When the vehicle is idling and slow, it reduces the radiant heat flow and also has a certain effect of blocking the direct convection heat exchange between hot air and the car body. Therefore, the heat shield is required to dissipate heat as quickly as possible. At high speeds, its role is basically limited to reducing the transfer of radiant heat flow, because the air flow at the bottom of the car body is faster at this time, which has a cooling effect on the heat-generating components. That is, the convection heat exchange at this time will be beneficial to the heat dissipation of the bottom parts of the car. Therefore, the market is in urgent need of a punching fixture for the processing of automotive heat shields.

[0003] However, the prior art still has the following problems:

[0004] Firstly, when the existing punching fixtures for automobile heat insulation boards are fixing the heat insulation boards, since the heat insulation boards are relatively soft, most of them cannot completely fix the heat insulation boards. Therefore, when punching the heat insulation boards, the heat insulation boards are prone to shaking, which may cause the punching to be misaligned and easily lead to damage to the heat insulation boards.

[0005] Secondly, the existing punching fixture for processing automobile heat insulation panels can generally only punch one hole at a time when punching the heat insulation panels, and the punching device needs to be moved continuously to punch holes. This punching method is too complicated and greatly affects the subsequent production efficiency.

[0006] In view of the above problems, the inventor proposes a positioning mechanism for a computer transmission line to solve the above problems. Utility Model Content
