Description

Water guiding device for machine tool

The invention mainly relates to a water guiding device of a machine tool, in particular to a water jet hole angle which can quickly adjust the water ball, so that the injected liquid can be accurately injected into the target object, so as to achieve fast and precise adjustment effect.

Today, the lathe or other turning technology is widely used in the processing industry, mainly because the lathe processing technology has a variety of cutting functions, and can be applied to the processing of various materials, and generally in the process of cutting, the tool and the workpiece will be high speed The friction generates heat, and if the accumulated temperature is too high, the tool wear or the workpiece may be deformed. In order to prevent the above situation, a water jet head is set on the machine tool to spray the machining fluid (water, cutting fluid, etc.) between the tool and the workpiece on the machine tool to reduce the temperature and increase the distance between the tool and the workpiece. Lubricity.

The general lathe processing machine, which is used for the jetting head of the injection machining fluid, although the angle of the nozzle can be adjusted to achieve the desired effect, there are still some shortcomings, as shown in the eleventh figure, which is the water guiding device of the processing tool. 1a, the general water guiding device 1a can be installed in the hole 101a of the water guiding seat 10a, and the hole 101a is provided with a first step groove 102a on the top surface, and the water guiding device 1a includes the head screw 2a, the washer 3a and the water ball 4a, the washer 3a is disposed at the bottom of the groove of the step groove 102a, and the water ball 4a is stacked on the washer 3a, and then locked by the head screw 2a at the adjacent hole 101a of the water guide seat 10a, and pressed Positioned against the water ball 4a.

Although the conventional technology can achieve the effect of adjusting the water jet direction of the water ball, it still has the following deficiencies, please match the twelfth map. First, the head end of the screw is directly pressed against the water ball. Peripheral, if you want to re-adjust the angle, you must first loosen the head screw. After adjustment, lock the head screw again to limit the water ball from the hole. Such complicated adjustment steps will waste work time and affect work efficiency. Second, the water ball ball has a limited range of water discharge. If the water ball is rotated too much, the water hole of the water ball is covered by the gasket, which causes the machining fluid to fail to be sprayed as scheduled, which cannot effectively prevent the tool and tool from overheating, or other processing problems. occur. 3. If the gasket cannot be pressed tightly against the bottom of the groove, the machining fluid easily oozes out from the gap between the groove and the gasket, so that the amount and strength of the injection of the machining fluid cannot reach the preset effect, which affects the processing flow and The quality of the finished product. 4. In order to allow the water ball 4a to be smoothly installed into the step groove 102a, the groove wall of the step groove 102a of the prior art is set to a flat surface, and only the tip end of the head screw 2a is pressed against the circumference of the water ball 4a. When the machining fluid is injected, the force of the injection of the machining fluid causes the water ball 4a to slide toward the slot of the step groove 102a. Thus, the water ball 4a is easily slipped away from the step groove 102a during the machining.
