Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to part processing positioning device technical field, concretely is a kind of manual positioning device. BACKGROUND
[0002] In modern manufacturing industry, accurate positioning is the key link to ensure product quality and production efficiency. Especially in the field of mechanical processing, the positioning accuracy of parts is extremely high, which is directly related to the quality and performance of the final product. In order to realize high-precision positioning, various positioning devices are widely used in production line.
[0003] The traditional positioning device usually adopts the way of evenly opening multiple hole positions on the workbench, and uses the positioning block with plug rod on the top. This design allows the positioning block to be inserted into the hole position of the workbench through the plug rod, so as to realize the fixation of the positioning block on the workbench. Once the positioning block is fixed, the parts to be processed can be accurately positioned and positioned to ensure the stability and accuracy of the parts during processing.
[0004] However, this positioning method has some obvious shortcomings. Because of the physical contact between the positioning block and the part to be positioned, long-term use will cause wear between the two. Wear will gradually affect the positioning accuracy, causing the size deviation of the processed parts to increase, which cannot meet the production demand of high precision. In order to restore the positioning accuracy, it is necessary to replace the worn positioning block regularly.
[0005] Replacing the entire positioning block not only consumes time and effort, but also has high cost. The positioning block is usually made of high-wear-resistant material to withstand continuous friction and pressure. Therefore, the cost of the positioning block is relatively high, and frequent replacement will increase production cost and reduce production efficiency. In addition, replacing the positioning block may also cause the production line to stop working, further affecting the production efficiency and delivery time. INVENTION CONTENTS
