Tailstock with cooling device and water nozzle

Abstract

The invention provides a tailstock with a cooling device and a water nozzle. The tailstock with the cooling device and the water nozzle comprises various tailstocks, water nozzles and cooling devices. The tailstock with the cooling device and the water nozzle is characterized in that the tailstock is arranged on a machining device, a tailstock shaft is arranged on the tailstock, a conic hole is formed in the inner side of the front end of the tailstock shaft and is connected with a conic handle or a tail sleeve, a connecting opening is formed in the top end of the inner side of the tailstock shaft and is communicated with the outer portion through a cooling hole formed in the tailstock shaft; or the connecting opening formed in the top end of the inner side of the tailstock shaft is provided with a threaded hole; or a cooling nozzle, namely the water nozzle, is arranged on the threaded hole and the cooling nozzle is communicated with a connecting opening formed in a cutter handle in a matched mode. In the process of machining, cooling liquid is directly injected to the cutting portion through a cooling pipeline arranged on a cutter, the cutting temperature is effectively reduced, scraps can be directly pushed out through liquid pressure of the cooling liquid, and the cutting resistance is reduced.

Description

Technical field: [0001] The invention relates to a tailstock with a cooling device and a nozzle, which is used in machining. Background technique: [0002] At present, the tailstock used in machining is composed of a tailstock and a tailstock shaft. The inner tapered hole on the tailstock shaft is matched with the tailstock connecting sleeve. The inner top of the inner tapered hole is provided with a flat hole, and the flat hole and the tailstock The flat shank of the connecting sleeve cooperates with the positioning. The existing tailstock does not have the cooling function, and the tool tends to generate a lot of heat during cutting, especially when drilling and milling workpieces with high hardness. The current cooling technology Water pipes are added from the outside to cool down. It is difficult for the coolant to enter the inside of the workpiece to cool down during the rotating cutting process. Therefore, the cooling effect is very poor, resulting in a decrease in the...

[0002] At present, the tailstock used in machining is composed of a tailstock and a tailstock shaft. The inner tapered hole on the tailstock shaft is matched with the tailstock connecting sleeve. The inner top of the inner tapered hole is provided with a flat hole, and the flat hole and the tailstock The flat shank of the connecting sleeve cooperates with the positioning. The existing tailstock does not have the cooling function, and the tool tends to generate a lot of heat during cutting, especially when drilling and milling workpieces with high hardness. The current cooling technology Water pipes are added from the outside to cool down. It is difficult for the coolant to enter the inside of the workpiece to cool down during the rotating cutting process. Therefore, the cooling effect is very poor, resulting in a decrease in the hardness of the cutter head, causing wear and even melting of the cutter head, and causing damage to the tool and processing. The scrapping of workpieces may even cause serious production accidents, and more likely to cause industrial injuries. At the same time, the tailstock with cooling device does not have the function of cooling, so that the cutting resistance of the tool is large, and it also causes damage to the equipment.
