Description

Technical Field

[0001] The invention relates to the technical field of tooling fixtures, in particular to a groove grinding tool with a movable positioning function of a slider. Background Art

[0002] At present, in the batch groove grinding processing of small workpieces, a batch workpiece clamping method is usually adopted to ensure the consistency of the grinding groove position. Standard steel blocks are usually used to fix them on all sides, and the workpieces to be grooved are inserted side by side in a closed area surrounded by multiple standard steel blocks. Although this positioning clamping method is simple and has high groove grinding efficiency, its groove grinding accuracy still has large errors. First, the workpieces are arranged into workpiece groups and fixed on all sides by standard steel blocks. However, there are slight errors in the size of the workpieces themselves. Relatively large workpieces will be clamped by standard steel blocks, while relatively small workpieces have nowhere to support them, which makes it very easy for workpieces to shift during groove grinding. Secondly, the workpieces are fitted together, resulting in the feed and push of each workpiece being affected by its upper and lower workpieces. If one is wasteful, all will be wasteful. Finally, although the grinding grooves on each batch of workpiece groups can basically ensure the consistency of position and error after the positioning is completed, there are still large errors between workpieces positioned in different batches.

[0003] Therefore, how to design a groove grinding tool that can separate the workpieces on the basis of synchronous positioning of multiple workpieces, and independently clamp and position each workpiece to avoid mutual interference in the positioning of the workpieces and avoid the situation where all workpieces are wasted if one is wasted, is a technical problem that needs to be urgently solved by technical personnel in this field.

[0004] Through public patent search, the following comparative documents were found:
