Description

Technical Field

[0001] The utility model relates to the technical field of tooling fixtures, in particular to a pneumatic fixture for CNC machining of radiators. Background Technique

[0002] A heat sink is a device for dissipating heat from heat-generating electronic components in an electrical appliance. It is mostly made of aluminum alloy, brass or bronze in the form of plates, sheets, multi-sheets, etc. For example, a CPU central processing unit in a computer requires a quite large heat sink, and power tubes, line tubes in a TV set, and power amplifier tubes in a power amplifier all require heat sinks. Generally, a layer of thermal grease needs to be applied to the contact surface between the electronic component and the heat sink during use, so that the heat generated by the component can be more effectively conducted to the heat sink and then dissipated into the surrounding air through the heat sink. Fixtures are required for the processing of radiators;

[0003] For example, the publication number is CN220388659U, a fixture for radiator processing, including a base, a sliding component installed on the base, a first driving component and a second driving component, a first buffer component and a second buffer component, a first adjusting component installed on the first buffer component, a second adjusting component installed on the second buffer component, a first clamping component installed on the first adjusting component, and a second clamping component installed on the second adjusting component. One end of the first driving component is installed on the base, the other end of the first driving component is installed on the sliding component, one end of the second driving component is installed on the base, the other end of the second driving component is installed on the sliding component, one end of the first buffer component is installed on the first driving component, the other end of the first buffer component is installed on the sliding component, one end of the second buffer component is installed on the first driving component, and the other end of the second buffer component is installed on the sliding component;

[0004] The above application drives the first buffer component to move through the first driving component arranged, the movement of the first buffer component drives the first adjusting component to move, the movement of the first adjusting component drives the first clamping component to move, so that the first clamping component approaches or moves away from the second clamping component. The second driving component is used to drive the second buffer component to move, the movement of the second buffer component drives the second adjusting component to move, and the movement of the second adjusting component drives the second clamping component to move, so that the second clamping component approaches or moves away from the first clamping component. In this way, the clamping or removal of the radiator can be realized, and the sliding component is used to cooperate with the above movement. The first adjusting component can adjust the angle of the first clamping component, and the second adjusting component can adjust the angle of the second clamping component. In this way, radiators of various shapes can be clamped without changing the fixture again, which saves time and effort and improves production efficiency. However, its fixing speed is slow during fixing, and the positioning accuracy is not high enough, which affects the processing efficiency of the radiator. Therefore, there is an urgent need in the market to develop a pneumatic fixture for CNC machining of radiators to help people solve existing problems. Utility Model Content
