Novel numerical control flat grinder

Abstract

The invention provides a novel numerical control flat grinder and has the function of matching a servo motor with a synchronical toothed belt to realize automatic feeding of an X shaft and a Z shaft. A guide block adopts a pull-up type to drive a spindle motor to move up and down. With the novel numerical control flat grinder, the existing general wedge type column is changed to a square column in shape, and tool motor control cabinet and control panel connected with each other are arranged in the novel numerical control flat grinder to realize a CNC (computer numerical control) function. The novel numerical control flat grinder has automatic feeding function, improves production efficiency, reduces labor strength, improves feeding accuracy, guarantees production stability and integrity, increases feeding accuracy and feeding speed of lifting lean screws, prolongs service life of the lifting lean screws, improves rigidity of column structure, and further guarantees feeding accuracy.

Description

technical field [0001] The invention relates to the field of surface grinder manufacture, in particular to a novel numerically controlled surface grinder. Background technique [0002] For various planes with high surface quality requirements, surface deep processing or finishing is required. The usual processing method is surface grinding, and the commonly used machine tools for surface grinding are surface grinders. A surface grinder is a kind of grinding machine, which mainly uses a grinding wheel to rotate and grind the workpiece to achieve the required flatness. When using a surface grinder to process the surface flatness of the workpiece, the working surface of the grinding wheel is used to grind the plane of the workpiece to be processed. The working surface of the grinding wheel can be its cylindrical surface or its axial end surface. [0003] When the cylindrical surface of the grinding wheel is used to grind the surface to be processed of the workpiece, the main ...

Problems solved by technology

[0007] (1) For the modified grinding machine that adopts the hydraulic drive device as the automatic power output, there are problems such as large oil consumption of hydraulic oil, high power consumption, serious oil leakage and high production cost and maintenance cost; and it is generated during the production process The noise is loud, which is harmful to the health of workers

[0008] (2) For the modified grinding machine that uses the motor as the automatic power output, the motor spindle is usually directly or indirectly connected to the driven part (such as the lead screw) through a coupling; in this case, it is necessary to ensure that the two shafts connected If the shaft ends are not aligned well, it will cause vibration or even damage the bearings, which will make installation difficult; and during use, it is necessary to regularly check whether the shaft ends are aligned and correct them, otherwise it is bound to Affects the feed accuracy and the quality of the grinding plane

[0012] In the actual use process, the applicant found that the lifting screw 6 is deformed to a certain extent when the lifting screw 6 is rotated upward to drive the guide block 72 to move upward along the track in the top-up driving mode adopted for the guide block 72 . When using the grinding head 83 to grind the workpiece, the radial force from the grinding head 83 is transmitted to the guide block 72 through the main shaft 82 and then acts on the lifting screw 6, because the lifting screw 6 is deformed and the deformation force is the same as that from the grinding head 83. The radial force is opposite, so it will increase the deformation of the lifting screw 6, affect the accuracy of feeding, and reduce the life of the lifting screw 6
