Description

Technical Field

[0001] The utility model relates to a machine tool for grinding crankshafts, and particularly to a grinding machine water nozzle. Background Art

[0002] The working principle of a double-sided grinding machine is to simultaneously grind two parallel surfaces of a workpiece through the end faces of two grinding wheels, so that the grinding of two parallel end faces can be completed in one processing process. The working principle of the grinding machine water nozzle is to eject a high-speed water flow, which can help carry away the heat in the grinding area, and this is very important for improving the processing efficiency and protecting the surface quality of the workpiece.

[0003] For example, a double-sided grinding machine cooling water nozzle with the patent number 201920311697.2 is provided with a water nozzle body and a baffle. The water nozzle body and the baffle form a liquid storage cavity. A plurality of gaps are provided at the front end of the water nozzle body, and the gaps are communicated with the liquid storage cavity, and the distances between the gaps and the object to be cooled are the same. However, the volume of this water nozzle is relatively large. When changing the production of crankshafts with different widths in production, especially when the width of the crankshaft is relatively narrow, it is easy to interfere with the shaft shoulders of the crankshaft, and the water nozzle needs to be replaced, which affects the production change efficiency. And the water flow of this water nozzle is small, resulting in poor cooling effect during grinding, and it is easy to cause grinding burns on the crankshaft diameter. Summary of the Utility Model

[0004] To solve the problems in the background art, the utility model proposes a grinding machine water nozzle, which can provide a large flow of water for the machine tool, increase the flushing area, help prevent the occurrence of burns during grinding of the grinding wheel, and the structure of this water nozzle is reasonable, simple to manufacture, and convenient to operate, and it can be applicable to crankshafts with various widths.

[0005] To achieve the above object, the utility model adopts the following scheme:

Either end of the mounting bracket is connected with a main water nozzle with adjustable height. The main water nozzle is arranged above the grinding wheel of the grinding machine. At least one side water nozzle is respectively arranged on both sides above the main water nozzle. The side water nozzle is arranged on the mounting bracket through a mounting seat.

[0007] Further, the mounting bracket is an arc body with a central angle less than 180°, and is arranged at the top of the mounting bracket close to the grinding wheel of the grinding machine.

[0008] Further, connecting seats are oppositely arranged on the left and right sides of the end of the mounting bracket connected with the main water nozzle. A rotating shaft is connected between the two connecting seats and the water inlet end of the main water nozzle.

[0009] Furthermore, a plurality of first water outlet pipes are detachably provided at the water outlet end of the side water spray nozzles. The plurality of first water outlet pipes are arranged in a direction parallel to the side surface of the grinding wheel of the grinding machine, and the water outlet ends of the plurality of first water outlet pipes incline towards the grinding wheel of the grinding machine.

[0010] Furthermore, a plurality of second water outlet pipes are detachably provided at the water outlet end of the main water spray nozzle. The plurality of second water outlet pipes are arranged in a direction tangent to the circumferential surface of the grinding wheel of the grinding machine. A bending portion is provided at the water outlet end of the plurality of second water outlet pipes towards the grinding wheel of the grinding machine. The total width of the plurality of second water outlet pipes is less than or equal to the thickness of the grinding wheel of the grinding machine.

[0011] Furthermore, both the first water outlet pipe and the second water outlet pipe are stainless steel water outlet pipes with an inner diameter of φ2.

[0012] The beneficial effects of the present utility model are as follows: The main water spray nozzle arranged above the grinding wheel of the grinding machine in the present utility model flushes the grinding wheel of the grinding machine and reduces the temperature of the circumferential surface of the grinding wheel of the grinding machine.

Moreover, the mounting bracket is an arc body smaller than a semi-circle, and the separate arrangement of the main water spray nozzle and the side water spray nozzles increases the compatibility of the water spray nozzles with different crankshafts. When changing products, there is no need to frequently replace the water spray nozzles, which improves the production change efficiency.

[0014] Furthermore, the plurality of first water outlet pipes are arranged parallel to the side surface of the grinding wheel of the grinding machine, and moreover, their water outlet ends incline towards the grinding wheel of the grinding machine, which is beneficial for the water flow to contact the grinding wheel and increases the flushing area; the water outlet end of the second water outlet pipe is provided with a bending portion downward, which is beneficial for approaching the circumferential surface of the grinding wheel, and is arranged in a direction tangent to the circumferential surface of the grinding wheel of the grinding machine, which is beneficial for increasing the flushing area.
