Embodiment Construction

[0010] Such as figure 1 As shown, the single-axis multi-wheel tap grinding device includes a belt pulley 1, a grinding wheel spindle 2 and a grinding wheel frame 3. The rear end of the grinding wheel spindle 1 is connected to the pulley 1, and the belt pulley 1 drives the grinding wheel spindle 2 to rotate. Affixed to the grinding wheel frame 3, the grinding wheel frame 3 is provided with a rough grinding wheel 4, a middle grinding wheel 5 and a fine grinding wheel 6 from front to back.

[0011] When working, the workpiece 7 is installed under the grinding wheel through the tooling, and the front end of the workpiece 7 enters from the outside of the rough grinding wheel 4. Driven by the tooling, the workpiece 7 moves towards the rear end of the grinding wheel spindle 2 while rotating slowly and uniformly. , the rough grinding, medium grinding and fine grinding are completed at one time to form the finished tap. During the work, the rough grinding wheel 4 removes the allowance...

Abstract

The invention discloses a screw tap grinding device, in particular a single-shaft multi-grinding-wheel screw tap grinding device. The single-shaft multi-grinding-wheel screw tap grinding device comprises a belt wheel, a grinding wheel main shaft and a grinding wheel frame, wherein the back end of the grinding wheel main shaft is connected with the belt wheel; the grinding wheel main shaft is driven to rotate through the belt wheel; the grinding wheel frame is fixedly connected to the grinding wheel main shaft; and a rough grinding wheel, a medium grinding wheel and a fine grinding wheel are mounted on the grinding wheel frame from front to back in sequence. As three grinding wheels with different thicknesses are respectively mounted on the grinding wheel main shaft, when the rough grinding, the medium grinding and the fine grinding are performed for workpieces, the replacement of the grinding wheels and the loading / unloading of the workpieces are not frequently needed for multiple times, finished products can be processed through once clamping, the quality defect caused in multiple times of clamping and grinding is prevented, multiple troubles are saved, the working efficiency is improved, and the grinding quality and the precision requirement are guaranteed.

Description

technical field [0001] The invention relates to a tap grinding device, in particular to a single-axis multi-grinding wheel tap grinding device. Background technique [0002] The thread on the blade of the tap is realized by multi-process grinding during the manufacturing process, and rough grinding, medium grinding and fine grinding are all required during grinding. The grinding wheels used for coarse grinding, medium grinding and fine grinding are different. Coarse grinding wheels are used for coarse grinding, and fine grinding wheels are used for vice versa. Existing rough grinding, intermediate grinding and fine grinding processes need to replace each process with a suitable grinding wheel. Such a change will not only delay time, but also make it difficult to guarantee the grinding quality, and also waste manpower. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of low work efficiency, poor quality and labor-intensive ...
