Problems solved by technology

[0004] In the existing grinding machine, the above-mentioned process of changing the grinding wheel is completely manual, and when changing the grinding wheel, the cooling water pipe needs to be twisted first to make room for the operation of changing the grinding wheel. After the new grinding wheel is installed, the cooling water pipe needs to be twisted to reset it. The process operation steps are many and cumbersome, resulting in a long downtime of the grinding machine when changing the grinding wheel, which affects the processing efficiency

Embodiment 1

[0034] like figure 1 As shown, the grinding machine includes a bed 8 , a grinding wheel assembly and a headstock 9 arranged on the bed 8 .

[0035] Specifically,

[0036] The headstock 9 includes a case 9a that slides forward and backward on the bed 8, a spindle seat 9b that slides up and down on the case 9a, and a spindle 9c that is horizontally provided on the spindle seat 9b. Among them, the chassis 9a is arranged on the bed 8 through the cooperation and sliding of the guide rail slider, and automatically moves back and forth through the motor screw transmission mechanism or the cylinder or the oil cylinder; Motor lead screw transmission mechanism or cylinder or oil cylinder drive move up and down automatically;

[0037] like figure 1 and image 3 As shown, the left side of the main shaft 9c is provided with a support 10, and the support 10 is provided with a turntable 11 and a motor 12 for driving the turntable 11 to rotate around its own axis. The body 8 is provided ...

Embodiment 2

[0053] The structure and principle of the second embodiment are basically the same as the first embodiment, the difference is that the plug-in structure includes a cylinder formed on the outer wall of the closed end of the water pipe 5 and a pipe formed on the support plate 3, the cylinder The shape and size of the cylinder are matched with the pipe body, and the cylinder is snapped into the pipe body.

Embodiment 3

[0055] The structure and principle of the third embodiment are basically the same as those of the first embodiment, except that the seal 15 is an annular rubber pad, and the bottom wall of the large hole 14c is provided with an annular groove 2 for placing the annular gasket, and the annular seal The two end surfaces of the pad are respectively pressed on the second bottom wall of the annular groove and the end surface of the annular shoulder 5b.

Abstract

The invention provides a grinding machine, and belongs to the technical field of machinery. The problem that a grinding wheel of an existing grinding machine is inconvenient to replace is solved. The grinding machine comprises a machine body, a grinding wheel assembly and a spindle box, the spindle box comprises a machine box arranged on the machine body in a front-back sliding mode, a spindle seat arranged on the machine box in an up-down sliding mode and a spindle horizontally arranged on the spindle seat, and a support is arranged on the left side of the spindle and provided with a rotating disc and a motor used for driving the rotating disc to rotate around the axis of the rotating disc. The rotating disc is vertically arranged and located on the front side of the support. A driving structure for driving the support to horizontally move left and right to enable the turntable to be close to or away from the main shaft is arranged on the lathe bed; the grinding wheel assemblies are circumferentially and uniformly distributed on the turntable, each grinding wheel assembly comprises a horizontally arranged grinding wheel shaft, a supporting plate fixed on the turntable and a cutter holder fixed on the supporting plate, the axes of the grinding wheel shafts and the main shaft are parallel, a grinding wheel is mounted at one end of each grinding wheel shaft, and a cutter groove for clamping the other end of each grinding wheel shaft is formed in each cutter holder. The grinding machine can realize automatic replacement of the grinding wheel.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a machine tool, in particular to a grinding machine. Background technique [0002] A grinding machine is a machine tool that uses abrasive tools to grind the surface of a workpiece, and most grinding machines use high-speed rotating grinding wheels for grinding. [0003] After working for a long time, the precision of the grinding wheel will change greatly. At this time, the grinding wheel needs to be removed for correction. In order not to delay the grinding progress, a new grinding wheel is usually replaced first. In order to prolong the life of the grinding wheel and improve the grinding To improve the grinding quality, cooling water pipes are generally arranged around the grinding wheel to spray cooling water to the grinding position. [0004] In the existing grinding machine, the above-mentioned process of changing the grinding wheel is completely manual, and when changing ...
