Abstract
The utility model provides a combined type spring clamp, and aims at providing a combined clamp provided with elasticity, and solving the problem of rapid replacement of a workpiece. The concrete embodiment of the combined type spring clamp is characterized in that, several narrow through grooves are machined at equal spacing at the periphery of a cylindrical clamping member, an outer conical surface cooperated with the inner conical surface of a frame is machined at the external side of the right end of the clamping member, and a workpiece clamping step is machined at the internal side of the right end of the clamping member. When the workpiece is placed in the step, the clamping member is moved leftwards, due to cooperation effect of the internal and external conical surfaces, the clamping member contracts, making the workpiece be clamped for being machined. When the clamping member is moved rightwards, the internal and external conical surfaces are disengaged, the clamping member expands, and the workpiece falls off.
Description
Technical field
The utility model relates to a kind of technological equipment, specifically, is a kind of combined type spring perch.
Background technology
Technological equipment refers to the general name of various tool used in the manufacture process. comprise cutter, anchor clamps, mould.Frock is its general abbreviation. frock is divided into special tooling, general frock, standard frock.Anchor clamps are the devices in order to clamping workpiece or guiding cutter.Cutter, the cutter that uses in the machine-building all are used for cutting metal material basically, so " cutter " speech generally just is interpreted as metal cutting tool.Accessory refers generally in order to connect the instrument of cutter and lathe.Anchor clamps are to add to be used for rapid fastening workpiece man-hour, make lathe, cutter, workpiece keep the process unit of correct relative position.That is to say that frock clamp is the indispensable parts of machining; Machine tool technology at a high speed, under efficient, accurate, compound, intelligent, the drive that the environmental protection direction develops, clamp technology just develops towards high-precision, efficient, module, combination, general, economic direction.On lathe during processing work, for the surface that makes workpiece can reach the size, geometry of drawing regulation and must use anchor clamps with other surperficial mutual alignment precision.In a broad sense, any operation in technical process is used for installing rapidly, easily and safely the device of workpiece, all can be described as anchor clamps.Use jig, help guaranteeing machining accuracy, the stabilized product quality of workpiece; Help raising labour productivity and reducing cost; Help improving workman's working condition, guarantee safety in production; Help enlarger bed process scope, realize " a tractor serves several purposes ".Anchor clamps are usually by setting element (confirming the tram of workpiece in anchor clamps), clamping device, the relative position of confirming cutter and workpiece or guiding tool orientation; Make workpiece in once mounting, can accomplish the processing of several stations, move two types of indexing means, Connection Element and anchor clamps etc. by circular index device and straight line and form.
Therefore, to updating of technological equipment be improve the machining level important by way of.With regard to anchor clamps, must adapt to rapid fastening workpiece, make lathe, cutter, workpiece keep the technological requirement of correct relative position, also to use standard component as far as possible, realize a tractor serves several purposes, to cut down finished cost.
