Description

Technical Field

[0001] This utility model relates to the field of CNC machine tools, and in particular to a transverse grinding head body for CNC machine tools. Background Technology

[0002] Most existing CNC machine tool grinding heads are vertically positioned and can only move up and down for grinding, making it difficult to achieve multi-angle grinding. This requires manual adjustment of the position and angle of the workpiece to be ground, which easily leads to defective products. Utility Model Content

[0003] This utility model aims to solve at least one of the technical problems existing in the prior art.

[0004] Therefore, the technical solution adopted by this utility model to solve the technical problem is as follows: A transverse grinding head body for CNC machine tools is provided, including a grinding head body body with an L-shaped cross-section. The grinding head body body includes a horizontally arranged counterweight and a grinding body formed on one side of the counterweight. A through hole is opened in the middle of the grinding body, and a grinding head mechanism is arranged in the through hole. The grinding head mechanism includes a spindle, a copper sleeve is fitted in the middle of the spindle, and a shaft washer is fitted on the outer side of the end of the spindle located away from the copper sleeve. A steel sleeve is also fitted, and an annular step is formed on the outer side of the main shaft at the other end of the copper sleeve. A front skeleton oil seal is fitted on the side of the main shaft away from the copper sleeve at the annular step. A rear skeleton oil seal is also fitted on the side of the steel sleeve near the shaft washer. A front pressure cover is also provided on the side of the main shaft away from the copper sleeve at the front skeleton oil seal. A rear pressure cover is also provided on the side of the steel sleeve away from the copper sleeve at the rear skeleton oil seal. A fastening flange is also fixedly installed on the end of the main shaft away from the copper sleeve at the front pressure cover. A pulley is also fixedly installed on the end of the main shaft away from the copper sleeve at the steel sleeve.

[0005] Preferably, the grinding body is also formed with an oil hole below the through hole, and an oil passage is installed in the oil hole.

[0006] Preferably, the two ends of the inner wall of the copper sleeve are tightly fitted with the main shaft, the middle of the inner wall of the copper sleeve is formed with a groove, the outer wall of the copper sleeve is formed with an oil inlet groove, and a capillary oil tube is also formed inside the copper sleeve, which connects the oil inlet groove and the groove.

[0007] Preferably, the oil passages are designed with outlets at both the annular step and the location of the copper sleeve near the shaft washer, with the oil inlet groove connected to the outlet. This allows for pressurization of the oil passages via an external pressurizing device, thereby supplying lubricating oil to the copper sleeve and ensuring adequate lubrication even for the transversely positioned copper sleeve.

[0008] Preferably, both the front and rear pressure covers are rotatably sleeved on the main shaft and fixed to the grinding head body with bolts.

[0009] Preferably, a spindle nut is also fixedly installed on the side of the spindle away from the steel sleeve.

[0010] Preferably, the spindle has a nut fixing key formed on the side of the pulley near the steel sleeve.

[0011] Preferably, the top surface of the counterweight has several mounting grooves formed thereon.

[0012] The beneficial effects of this utility model are as follows: This utility model adopts a horizontal grinding head body structure, and divides the grinding head body into a counterweight body and a grinding body. When in use, only the counterweight body needs to be assembled into the CNC machine tool to achieve horizontal grinding. Moreover, during the grinding process, only by changing the position of different mounting slots of the grinding head body, multi-angle adjustment in the up, down, left and right directions can be achieved, which improves the yield and processing efficiency.
