Description

Technical Field

[0001] This utility model relates to the field of centerless grinding machine technology, specifically to a centerless grinding water nozzle mechanism. Background Technology

[0002] A centerless grinder is a type of grinder that does not require workpiece axis positioning for grinding. It mainly consists of three mechanisms: a grinding wheel, an adjusting wheel, and a workpiece support. The grinding wheel is responsible for the actual grinding work, the adjusting wheel controls the rotation of the workpiece and the feed rate, and the workpiece support supports the workpiece during grinding. These three components can be combined in several ways, except when grinding is stopped, but the principle is the same.

[0003] For example, application number CN202320863906.0 relates to the field of centerless grinding technology, providing a centerless grinding machine with an easily adjustable cooling nozzle. This centerless grinding machine includes a grinding base, a grinding wheel body mounted on one side of the upper part of the grinding base, a grinding wheel cover mounted on the upper exterior of the grinding wheel body, a transfer fluid tank mounted on the top of the grinding wheel cover, a first pipe mounted at the front of the transfer fluid tank extending into the interior of the transfer fluid tank, and a universal joint mounted on the top surface of the transfer fluid tank. A coolant nozzle is mounted at one end of the universal joint. Coolant circulation is achieved through the cooperation of a first water pump and a second water pump. Furthermore, the coolant is filtered by a filter plate, reducing the content of grinding debris in the coolant during the pump and pipeline transport process, indirectly protecting the pipeline and coolant nozzle, and increasing the practicality of the device.

[0004] Based on the aforementioned patent searches and the findings of existing equipment, while the aforementioned equipment can solve the problem in existing technologies where, when coolant is sprayed from the nozzle onto the workpiece for cooling, grinding generates debris that mixes with the coolant. After circulation by the water pump, the coolant carrying debris can adversely affect the inner wall of the pipes and the nozzle, even causing nozzle blockage, thus negatively impacting the cooling of the workpiece during grinding. However, in practice, the coolant nozzle is connected via a universal joint, and manual adjustment is still required when needed, preventing timely adjustments to the workpiece during grinding.

Simultaneously, the cooperation between the sliding plate 103 and the sliding groove 102 ensures the stability of the adjusting block 12 during movement, allowing the adjusting frame 8 to move the adjusting block 12. The adjusting block 12 then moves the coolant nozzle 7 through the fixed pipe 14. Simultaneously, the user can activate the motor 133, which drives the screw 132 to rotate. The rotating screw 132 then moves the threaded sleeve 131 back and forth, allowing the threaded sleeve 131 to move the adjusting block 12 inside the mounting groove 11. The adjusting block 12 then moves the coolant nozzle 7 back and forth through the fixed pipe 14, enabling multi-directional adjustment of the coolant nozzle 7 and achieving a convenient adjustment effect.

[0036] In summary, this centerless grinding water nozzle mechanism, by setting an adjusting block 12, allows the adjusting block 12 inside the adjusting frame 8 to adjust the position of the coolant nozzle 7 through the fixed pipe 14. This solves the problem that in the process of using a universal tube to connect the coolant nozzle, the coolant nozzle still needs to be manually adjusted when needed, making it impossible to adjust the workpiece in a timely manner during grinding.
