[0002] Drilling and grinding are common machining processes, which are usually used to make holes and finish the surface of workpieces respectively. Threaded clamps are a device used to fix workpieces or clamping tools. Threaded clamps are often used to fix the workpieces during machining. The advantage is that they can fix the workpieces quickly and safely.

However, it is difficult to replace the soft gaskets or pads after they are worn, which is very inconvenient. A lot of heat will be generated during processing, and the workpiece is easily deformed or damaged due to heat damage. Traditional thread tightening fixtures do not have a cooling function.

A liquid infusion tube 12 is fixedly installed on the upper end of the liquid storage tank 4, and one end of the liquid infusion tube 12 away from the liquid storage tank 4 is fixedly installed on the upper end of the liquid spraying device 11. The liquid storage tank 4 stores coolant, which is transmitted to the liquid spraying device 11 through the liquid infusion tube 12 and sprayed out, thereby reducing the temperature of the processing area during processing and reducing the accumulation of heat. The liquid spraying device 11 is a prior art and will not be described in detail here. When the motor 8 drives the rotating shaft 6 to rotate, the cam 7 rotates and reciprocates the extension block 10 through the connecting rod 9, so that the liquid spraying device 11 reciprocates horizontally on the limit rod 13, expands the heat dissipation area, and makes the heat dissipation effect better. The length of the liquid infusion tube 12 is sufficient to support the liquid spraying device 11 to reciprocate left and right. The limit rod 13 is rectangular and plays a limiting role when the liquid spraying device 11 reciprocates. A plurality of circular drainage holes are opened on the upper end of the waste box 1, and the sprayed coolant falls into the waste box 1 through the circular drainage holes, which is convenient for collecting the coolant.
