The choice of Vertical Toggle Clamp and its clamping method

Vertical Toggle Clamp usually consists of positioning element (to determine the correct position of the workpiece in the fixture), clamping device, tool setting guide element (to determine the relative position of the tool and the workpiece or guide the direction of the tool), indexing device (to make the workpiece in one installation It can complete the processing of several stations, including two types of rotary indexing device and linear moving indexing device), connecting elements and Vertical Toggle Clamp body (fixture base). Next, let's take a look at the selection of Vertical Toggle Clamp and the determination of the workpiece clamping method. Here are some answers.

Choice of Vertical Toggle Clamp.

CNC machining has two main requirements for Vertical Toggle Clamp: one is that the Toggle Clamp should have sufficient accuracy and rigidity; the other is that the Toggle Clamp should have a reliable positioning reference. When choosing Vertical Toggle Clamp, usually consider the following points: First, try to use adjustable fixtures, modular fixtures, and other general fixtures, avoid using special fixtures, to shorten the production preparation time. Second, consider the use of special fixtures during mass production, and strive to have a simple structure. Third, loading and unloading workpieces should be quick and convenient to reduce machine downtime. Fourth, the installation of the Vertical Toggle Clamp on the machine tool must be accurate and reliable to ensure that the workpiece is processed in the correct position.

Type of Vertical Toggle Clamp.

There are two main types of Vertical Toggle Clamp-on CNC lathes: one type is used for disc or short shaft parts. The workpiece blank is clamped in a chuck with adjustable jaws (three jaws, four jaws), and is driven by the chuck. The other type is used for shaft parts. The blank is installed between the center of the spindle and the center of the tailstock. The workpiece is rotated by a toggle chuck on the spindle. The Vertical Toggle Clamp on the CNC milling machine is generally installed on the worktable, and its form can be varied according to the characteristics of the workpiece to be processed, such as general-purpose bench vise, CNC indexing turntable, etc. In addition, the installation method of parts on CNC machine tools is the same as that of ordinary machine tools. It is necessary to choose the positioning reference and clamping plan reasonably. Pay attention to the following two points: first, strive to unify the design, process, and programming calculation benchmarks, which is beneficial to numerical calculation during programming. The simplicity and precision. Second, try to reduce the number of clamping times, and process all the surfaces to be processed after positioning and clamping once as much as possible.
