Main types of drilling fixture

main types of drilling fixture

drilling fixture is abbreviated as drilling fixture, which is mainly used to process holes and threads. It is mainly composed of drill sleeve, drill template, positioning and clamping device clamp. It is estimated that by 2019, the main types are as follows:

(1) fixed drilling jigs: in use, this kind of drilling jigs are fixed on the machine tool and have high processing accuracy. It is mainly used for processing single holes with large diameter on vertical drilling machines or parallel holes on radial drilling machines

(2) rotary drilling jig: this kind of drilling jig has an indexing device, so it can process several axial or radial hole systems distributed around the axis on the workpiece

(3) turnover drilling jig: it is mainly used to process holes on different surfaces of small workpieces, and the hole diameter is less than f8~f10mm. It can play a decisive role in industrial development to reduce the installation times and improve the position accuracy of the machined hole. Its structure is relatively simple, and the processing jig is generally turned over manually, so the fixture and workpiece should be less than 10kg

(4) cover type drilling jig: this kind of drilling jig has no clamp, its positioning element and clamping device are directly installed on the drilling template, and the drilling template is clamped on the workpiece, which is suitable for small hole processing on the bulky and bulky workpiece. The clamp and structure are simple and light, and it is easy to remove chips

(5) sliding column drill jig: sliding column drill jig is a general adjustable fixture with lifting drill template. This drill jig has the advantages of simple structure, convenient operation, rapid action and short manufacturing cycle. It is widely used in production, with a total growth rate of about 7% compared with all kinds of transmissions
