[0002] A heat sink is a device that dissipates heat from heat-prone electronic components in electrical appliances. It achieves the purpose of reducing the temperature of electronic equipment or mechanical equipment through heat conduction and heat transfer. Heat sinks are usually made of aluminum alloy, brass or bronze, and can be in the shape of plates, sheets or multiple sheets. During the processing and assembly of heat sinks, the edges of heat sink parts need to be trimmed, but the existing trimming devices still have defects and deficiencies in some aspects that need to be improved:

[0003] The heat sink of claim 1, wherein the first and second clamping portions are provided on the frame, the first clamping portion being used to clamp the heat sink in a direction perpendicular to the upper and lower sides of the heat sink, and the second clamping portion being used to clamp the heat sink in a direction perpendicular to the two sides of the heat sink. The first clamping portion is located on the downstream side of the second clamping portion along the direction of the milling channel, and the first milling assembly is located on the downstream side of the second milling assembly. By performing surface processing on the heat sink to be processed before cutting and forming, the number of clamping times can be reduced and the product processing efficiency can be improved.

[0004] Most of the processing equipment in the above documents are manually driven, and the heat sink is driven forward by human power through the side of the machine. This has high safety risks and low efficiency, and the processing quality is unstable, so it is only suitable for rough processing;

[0005] Most of the finishing and processing equipment in the above documents are not enclosed and protected on the outside. When processing heat sink parts, the unprotected operating table poses a safety hazard to a certain extent.

[0006] Therefore, we propose a heat sink part edge trimming processing device to solve the above-mentioned problems. Utility Model Content

[0007] The purpose of the utility model is to provide a device for trimming and processing the edges of heat sink parts, so as to solve the problem proposed in the above-mentioned background technology that the heat sink is driven forward by manpower through the side of the machine, which has high safety risks and low efficiency, unstable processing quality, and is only suitable for rough processing.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a heat sink part edge trimming processing device, comprising a machine body, a PLC control box is fixedly connected to the upper side of the machine body, a start switch is fixedly connected to the upper side of the machine body, a placement seat is fixedly connected to the inside of the machine body, and a travel switch is fixedly connected to the front end of the placement seat, and a saw blade is fixedly connected to the machine body;

[0010] A placement seat; the placement seat is fixedly connected to the inside of the machine body, and a slider is fixedly connected to the top of the placement seat, and a universal base is nested and connected to the outside of the slider;

[0011] Furthermore, a protective door is fixedly connected to the front side of the roller, a cylinder is fixedly connected to the outer side of the front end of the machine body, and the output end of the cylinder is fixedly connected to the lower end of the protective door.

[0012] Furthermore, the rollers are provided in four groups, and the rollers and the protective door are integrated into one structure.

[0013] Furthermore, the roller forms a sliding structure with the limiting plate through the protective door, and the sliding of the roller does not exceed the maximum value of the length of the limiting plate.

[0014] Furthermore, a driving motor is fixedly connected to the universal base, and a gear is fixedly connected to the lower end of the driving motor.

[0015] Furthermore, a rack is fixedly connected to the side of the placement seat, and the rack and the gear are meshed with each other.

[0016] Furthermore, a plurality of through holes are provided in a rectangular array on the upper side of the universal base, and the universal base forms a sliding structure with the slider through the meshing action of the rack and the gear.

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

[0018] 1. When the machine body is processing the heat sink, it is fully enclosed on all sides. Through the rack, slider, cylinder, and PLC control box, it can achieve rapid positioning and uniform speed processing, which improves production efficiency and product quality, and also protects the labor safety of employees;

[0019] 2. When the machine body is processing the heat sink, the cylinder can be started and the protective door can be pushed to move by the cylinder.

Under the limiting effect of the limit plate, the protective door can move stably, so that the machine body is in a fully closed state when processing the heat sink, protecting the labor safety of the user;

[0020] 3. Start the machine body and make it run. The machine drives the saw blade to rotate at high speed. The driving motor moves forward quickly along the rack through the slider G01 until it is close to the saw blade and then performs slow and uniform processing movement G01. After the processing is completed, the cylinder moves upward and the safety door is opened. At the same time, the universal base moves backward along the slider and stops at the travel switch. At this time, the processing of the heat sink can be automatically completed, which improves production efficiency and product quality.

[0021] 4. When the driving motor is started, the driving motor will synchronously drive the gear to rotate. At this time, the gear and the rack are meshed with each other, and the position of the rack is fixed.
