Description

Technical Field

[0001] The utility model relates to the technical field of clamping, in particular to a product positioning and clamping device. Background Art

[0002] At present, with the development of industrialization and the progress of society, the market has higher and higher functional and performance requirements for precision parts and components, the structure of precision parts and components is becoming more and more complex, and the processing difficulty and precision requirements are also becoming higher and higher. In order to ensure the quality and precision of smart wearable parts processing, when processing parts with inclined holes, a fixture consistent with the angle of the inclined hole is required to adjust the required processing angle. A Chinese patent discloses a product clamping device (authorization announcement number CN217750430U), which discloses a product clamping device, which includes a clamping seat; a rotating drive mechanism, the rotating drive mechanism is arranged on the clamping seat for outputting a rotating drive force; a rotating bearing mechanism, the rotating bearing mechanism is rotatably arranged on the clamping seat and is connected to the rotating drive mechanism, and a loading position is formed on the rotating bearing mechanism; a product positioning plate, the product positioning plate is used to hold the product to be processed, and the loading position is used to accommodate the product positioning plate; and a locking mechanism, the locking mechanism is arranged on the rotating bearing mechanism and can lock or release the product positioning plate. The product clamping device of this solution can meet the requirement that one device supports the product to complete two different processing steps of outer contour and inclined hole. The number of equipment required is small, and the degree of automation is high. There is no need to assemble and disassemble the product many times. The assembly and disassembly takes a short time, the processing efficiency is high, the product processing size accuracy and consistency are good, which is conducive to ensuring the product processing quality. This patented technology solves the problem that the existing processing method is implemented in two independent processes: the first process is to process the contour of the product, which requires manual clamping and fixing of the product. After the contour is processed, the product needs to be removed and then clamped and fixed to the fixture of the second process. The second process is to process the inclined hole of the product. The fixture has an inclination corresponding to the inclined hole, which makes it inconvenient to disassemble and assemble the product. Two devices are required to complete the two processes, and at least two operators are required at the same time. Since the existing processing method requires manual clamping and removal of the product twice, the assembly and disassembly operations are cumbersome and time-consuming, and it is difficult to ensure the uniformity of the product clamping posture when switching to the second fixture, which easily leads to processing size errors; in addition, the time consumed by the fixture to adjust the inclination angle is long, which directly affects the processing efficiency of the product. The accuracy and consistency of the fixture to adjust the inclination angle are poor, which directly affects the precision of product processing, and then affects the coordination of the inclined hole with other spare parts.

[0003] However, in the prior art, during the product clamping process, due to the different sizes of products, different product fixtures need to be replaced for positioning when clamping different products. It is necessary to solve the problem of stable clamping and positioning of products of different sizes in the prior art.

[0004] Therefore, those skilled in the art have provided a product positioning and clamping device to solve the problems raised in the above background technology. Utility Model Content
