Description

Technical Field

[0001] The utility model relates to the technical field of numerical control grinders, in particular to a numerical control grinder with an automatic tool setting function. Background Art

[0002] The existing hydraulic surface grinder can automatically align the grinding wheel with the workpiece, so that the workpiece can be processed more accurately. A cover is provided on one side of the hydraulic telescopic frame of the hydraulic surface grinder, and the grinding wheel is installed inside the cover.

[0003] After a long period of grinding, the outer wall of the grinding wheel will be worn, resulting in poor connection between the grinding wheel and the workpiece.

[0004] The main reason for the above problems is that the cover is not equipped with a device for lubricating the outer wall of the grinding wheel. Due to the high hardness of the workpiece itself, a relative force will be generated between the workpiece and the grinding wheel during the grinding process, which will gradually increase the friction coefficient between them, resulting in poor processing smoothness. The contact time between the grinding wheel and a certain part of the workpiece is too long under the action of resistance, resulting in excessive processing of the workpiece, affecting the precise processing of the workpiece. To address the above problems, we propose a CNC grinder with automatic tool setting function. Utility Model Content

The CNC grinder body 1, the processing table 101, the hydraulic lifting frame 102, the cover shell 103 and the grinding wheel 2 constitute the MY618 hydraulic surface grinder. When it is in use, the control cabinet is controlled to automatically position the grinding wheel 2 and the workpiece, that is, the tool setting of the grinding wheel 2 is automatically completed, and the workpiece is placed on the top end face of the processing table 101. After the tool setting is completed, the switch is turned on to drive the grinding wheel 2 to rotate, so that the grinding wheel 2 grinds the workpiece.

[0030] A lubrication mechanism 3 is arranged inside the cover 103, and the lubrication mechanism 3 includes a first lubrication block 301 and a second lubrication block 302, and the first lubrication block 301 and the second lubrication block 302 are respectively in contact with the outer wall of the grinding wheel 2 at different positions, and the first lubrication block 301 and the second lubrication block 302 are both block-shaped molybdenum disulfide. After the lubrication blocks are applied to the outer wall of the grinding wheel 2, a uniform lubrication film is formed on the outer wall of the grinding wheel 2, which effectively reduces its friction coefficient. The first lubrication block 301 is against the arc-shaped outer peripheral wall of the grinding wheel 2, and the two groups of second lubrication blocks 302 are against the planar outer peripheral arms of the grinding wheel 2. The first telescopic rod 307 is used for connecting the first lubrication block 301 with the cover 103 and the second lubrication block 302 with the cover 103. The spring 308 is arranged on the outer wall of the first telescopic rod 307, and the spring 308 is used for the stable connection between the first lubrication block 301 and the second lubrication block 302 and the outer wall of the grinding wheel 2.

[0031] The inner wall of the housing 103 is provided with a first placement seat 303, and the interior of the first placement seat 303 is slidably connected with a clamping seat 306, one end of the first lubricating block 301 is clamped in the interior of the clamping seat 306, and a group of first telescopic rods 307 for limiting the position of the spring 308 are provided between one side of the clamping seat 306 and the inner wall of the first placement seat 303, and a group of second telescopic rods 309 for limiting the sliding of the clamping seat 306 are provided between one side of the clamping seat 306 and the inner wall of the second placement seat 304, and the interior of the second placement seat 304 is slidably connected with the clamping seat 306, and the second lubricating block 301 is clamped in the interior of the clamping seat 306.

[0032] A second placement seat 304 is provided on both sides of the first placement seat 303, and an electric telescopic rod 305 is provided on both sides of the first placement seat 303. One end of the electric telescopic rod 305 is connected to the second placement seat 304.

After the lubricating block is applied to the outer wall of the grinding wheel 2, a uniform lubricating film is formed on the outer wall of the grinding wheel 2, thereby effectively reducing its friction coefficient. In addition, by means of the first telescopic rod 307 and the spring 308, one end of the first lubricating block 301 and the second lubricating block 302 can be automatically driven to contact the outer wall of the grinding wheel 2, thereby avoiding the situation in which the first lubricating block 301 and the second lubricating block 302 do not contact the outer wall of the grinding wheel 2 after a part of them are consumed.
