Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of precision spare part positioning, specifically a high-precision mechanical spare part machining positioning device. BACKGROUND
[0002] It is well known that with the development of industrial technology, the machining precision requirement of mechanical spare parts is higher and higher. Especially in the fields of aerospace, precision instrument manufacturing, etc., the slight deviation of parts may lead to a substantial decline in the performance of the entire product. Therefore, how to ensure the accuracy of the parts during the machining process has become one of the key problems. In the traditional machining of mechanical spare parts, the positioning and clamping device mostly adopts a fixed clamping mode, that is, the structure of the clamp and the position of the clamping point are pre-set and cannot be adjusted according to the specific shape and size of the workpiece. This fixed mode is still applicable for standard circular or square workpieces, but it is not enough for polygonal or other irregularly shaped workpieces. In order to adapt to workpieces of different shapes, the operator usually needs to manually adjust the position of the clamp, which not only takes time but also is prone to human error, affecting the machining precision. During the machining process, especially under the conditions of high-speed cutting or strong impact, the stability of the clamp is crucial. The traditional clamping device often causes displacement or deformation of the workpiece during the machining process due to uneven distribution of clamping force or improper selection of clamping points, thereby affecting the machining quality, so it is necessary to propose a solution to this technical problem.
