Description

Technical Field

[0001] This utility model relates to the field of axial positioning technology, specifically to an axial positioning device for an external cylindrical grinding machine. Background Technology

[0002] External cylindrical grinding machines are a type of grinding machine specifically designed for machining the outer surfaces of cylindrical, conical, or other shaped workpieces, as well as the end faces of shaft shoulders. It is one of the most widely used types of grinding machines, capable of machining various cylindrical and conical outer surfaces and end faces of shaft shoulders. External cylindrical grinding machines can machine not only hard materials such as hardened steel and cemented carbide, but also brittle materials such as glass and granite.

[0003] In the process of realizing this utility model, the inventors discovered the following problems in the prior art that have not been solved: Although the existing axial positioning device for external cylindrical grinding machines has good adjustment and clamping positioning functions, the workpiece needs to be manually adjusted by the motor to achieve the gradual advancement of the workpiece. Before advancing, the grinding progress needs to be observed before advancing again. The degree of automation is low and a lot of effort is consumed. It is in urgent need of improvement. Therefore, we propose an axial positioning device for external cylindrical grinding machines. Utility Model Content

A bidirectional lead screw 32 is fixedly installed on the inner side of the drive shaft of the forward and reverse motor 33. The opposite threads on both sides of the bidirectional lead screw 32 are screwed into the pre-set screw holes in the slider b34 on the same side. The forward and reverse motor 33 can drive the bidirectional lead screw 32 to drive the slider b34 to move in opposite directions, which can adjust the clamping mechanism and is used for workpiece positioning. A drive motor 41 is fixedly installed on the inner side of the side plate 4. A grinding head 44 is fixedly installed on one side of the drive shaft of the drive motor 41. A vibration sensor 42 is fixedly installed on the top of the inner side of the side plate 4 through a bracket. A processor 43 is fixedly installed on the bracket. The data output terminal of the vibration sensor 42 is connected to the data input terminal of the processor 43. The signal output terminal of the processor 43 is connected to the signal input terminal of the servo motor 25. Data and signal transmission can be realized through the data cable and signal cable connection components to realize the control of the servo motor 25, which meets the usage requirements. A protective cover is fixedly installed on the outside of the processor 43.

[0024] In this technical solution, components such as threaded cylinder 22, slider a21 and vibration sensor 42 can be used together.

At the same time, the insertion rod 52 can be inserted into the insertion hole 54 at different positions and can be adjusted according to the grinding depth required by the workpiece. It has a wide range of applications and strong versatility.
