Description

Water-cooled spindle holder

The present invention relates to a spindle holder for a processing tool, and more particularly to a water-cooled spindle holder.

As shown in FIG. 1 , a processing tool commonly used in the industry includes a body 80 , a grinding mechanism 90 and a base A connected to the body 80 , and the grinding mechanism 90 includes a spindle seat. 91 and a grinding tool 92, one end of the main shaft seat 91 is fixedly coupled to the fuselage body 80, the grinding tool 92 is rotatably coupled with the main shaft base 91, and the grinding tool 92 and the fuselage body 80 are powered In connection, the abrasive tool 92 faces a reference processing surface A1 of the base A, and the abrasive tool 92 is a grinding wheel.

When the processing tool is actuated, the workpiece to be processed is placed on the reference processing surface A1, and the grinding tool 92 of the grinding mechanism 90 is driven by the body 80 to rotate, and the grinding tool 92 is used for grinding. The workpiece is processed.

However, the grinding mechanism 90 of the conventional processing tool will cause the temperature of the transmission shaft in the spindle housing 91 to rise due to the long use time, resulting in a slight deformation of the grinding tool 92, thereby affecting the processing tool. The precision of machining requires a water-cooled spindle holder.

The present invention provides a water-cooled spindle seat, the main purpose of which is to provide a water-cooled spindle seat capable of cooling the drive shaft and the spindle seat temperature, avoiding warpage of the spindle seat, and improving the working quality.

Another object of the present invention is to provide a water-cooled spindle mount that reduces the temperature of the vertical rail guide slots.

In order to achieve the above objective, the present invention relates to a water-cooled spindle seat mainly for combining a transmission bushing, the drive bushing has a drive shaft hole, and the drive shaft hole is provided with a drive shaft, and the drive shaft is provided with a power tool of the power tool, one end of the drive sleeve has an abrasive tool, and the water-cooled spindle seat includes:

An outer wall having a combined end portion for coupling with a machine tool, the outer wall having a water inlet hole and a water outlet hole for connecting a water inlet hole for connecting a water outlet;

a sleeve hole for receiving the transmission sleeve, wherein the direction of the extension of the transmission sleeve is defined as an axial direction, the sleeve hole is axially penetrated through the water-cooled spindle seat, and the side wall of the sleeve hole is one inside Wall;

In a cooling space, the cooling space is formed annularly between the outer wall and the inner wall, and the cooling space is provided for accommodating water for cooling, and the water inlet hole and the water outlet hole of the outer wall communicate with the cooling space.

Preferably, the outer wall further has a vertical track guiding groove for the vertical rail mounted on the machine tool, and the cooling space is adjacent to the vertical track guiding groove.

It can be seen from the foregoing that the water-cooled spindle holder of the present invention mainly forms the cooling space between the outer wall and the inner wall, and the water inlet hole and the water outlet hole of the outer wall communicate with the cooling space, and is injected from the water inlet hole. The low-temperature water discharges the high-temperature water from the water outlet hole to keep the cooling water in the cooling space low, and further reduces the temperature of the transmission shaft in the water-cooled spindle seat by reducing the cooling water. The temperature of the vertical track guiding groove and the cooling of the transmission shaft and the vertical track guiding groove prevent the warping deformation of the spindle seat and improve the working quality.
