Embodiment 1

[0040] Such as Figure 2-7 The shown tooling is used for grinding the oil groove of the spindle sleeve. The machine base 4 is installed flat on the workbench. The motor 1 is fixed on the upper part of the machine base 4. The output shaft of the motor 1 is equipped with the small pulley 2, the small pulley 3 and the large pulley. 5 is connected through the transmission of the belt 2, and the side of the machine base 4 is fixedly installed with a tensioning wheel 21 for tensioning the belt 2. The large pulley 5 is set on the outside of the first transmission shaft 6, and the first transmission shaft 6 runs through the base 4. On the side of the base 4 away from the large pulley 5, a swing shaft bracket 33 is fixedly installed, one of the swing shaft brackets 33 The first drive shaft 6 is set in the hole, and one end of the second drive shaft 7 is set in the other hole of the balance shaft bracket 33 .

[0041] The end of the first drive shaft 6 is equipped with a first fork 31,...

Embodiment 2

[0048] In this embodiment, only the connection method between the first sleeve 13 and the second sleeve 15 and the workpiece is different, and the rest refer to the first embodiment. Such as Figure 8 As shown, the first sleeve 13 is coaxially set on the outside of the workpiece 9, and the second sleeve 15 is coaxially set on the outside of the first sleeve, and the two are connected by threads. The inner surfaces of the first sleeve 13 and the second sleeve 15 are respectively provided with limiting bosses which limit the axial movement of the workpiece.

Abstract

The invention discloses a tool for grinding an oil groove of a spindle sleeve. The tool for grinding the oil groove of the spindle sleeve comprises a transmission mechanism, a reversing mechanism anda clamping mechanism. The transmission mechanism comprises a base, a motor is fixed on the base, and the motor is connected to a first transmission shaft through a belt transmission combination. The first transmission shaft is connected to a swing shaft bracket of the reversing mechanism, the end part is provided with a first swing rod, and the first swing rod is connected to the end face of the swing sleeve through a first connecting rod. The swing shaft bracket is also rotatably connected to a second transmission shaft. The second swing rod of a second transmission shaft is connected to a third swing rod through the second connecting rod. The third swing rod is fixed on the side of the swing sleeve. The tool can achieve fast and accurate grinding of oil groove of spindle sleeve, improveproduction efficiency and reduce the cost of production.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a tool for grinding the oil groove of a main shaft sleeve. Background technique [0002] The grinding wheel frame of the cylindrical grinding machine is an important part of the machine tool, and the oil groove on the spindle sleeve of the grinding wheel frame can ensure sufficient lubrication when the main shaft in the grinding wheel frame rotates at high speed. Oil tank such as figure 1 As shown, it is a wedge-shaped structure uniformly distributed along the circumference, and the precision requirements are relatively high in actual processing. If the oil groove is processed too deep, there will be too much oil between the spindle and the sleeve, which will affect the machining accuracy of the machine tool. If the oil groove is machined too shallow, the main shaft cannot be fully lubricated, and the dry friction between the main shaft and the sleeve will cause the phenomenon of "burst ...
