Abstract
The invention relates to a tool clamp in machining, and in particular to a simple screw clamping mechanism. The simple screw clamping mechanism comprises a base. A vertical hollow part is formed on the base, and a clamping block is arranged in the hollow part. The upper end of the clamping block is fixed to the hollow part of the base through a locating pin. The lower end of the clamping block is connected with one side of the base through a spring, and a handle is arranged at the position, opposite to the spring, of the other side of the base. The handle rotates inwards to compress the clamping block, the clamping block is driven to clamp a workpiece, and the clamping function is achieved. Conversely, the handle rotates outwards, elastic force is generated on the clamping block by the spring at this moment, the clamping block is driven to loosen the workpiece, and the workpiece is rapidly mounted and demounted. Furthermore, due to the fact that the locating pin is arranged at the end close to the workpiece, torque analysis shows that the workpiece can be clamped only through small force of the handle on the clamping block, and therefore the labor saving effect can be achieved.
Description
Technical field
The present invention relates to the frock clamp in a kind of machining, be specifically related to a kind of simple and easy screw clamping mechanism.
Background technology
Fixture is also known as jig.In a broad sense, any operation in technical process, is used for rapidly, installs easily and safely the device of workpiece, all can be described as fixture.Jig is the most common, often referred to as fixture.Fixture adds to be used for rapid fastening workpiece man-hour, makes lathe, cutter, workpiece keep the process unit of correct relative position.Fixture is usually by compositions such as setting element (determining the tram of workpiece in fixture), clamping device, tool setting induction element (determine the relative position of cutter and workpiece or guide tool orientation), indexing means (make workpiece can complete the processing of several station in once mounting, have circular index device and rectilinear movement indexing means two class), Connection Element and clamp bodies (clamp base).Fixture is conducive to the machining accuracy, the stabilized product quality that ensure workpiece; Be conducive to raising labour productivity and reducing costs; Be conducive to improving workman's working condition, ensure safety in production; Be conducive to enlarger bed process scope, realize " a tractor serves several purposes ".Frock clamp is the indispensable parts of machining, machine tool technology at a high speed, efficient, precision, compound, intelligence, environmental protection future development drive under, clamp technology is just towards high-precision, efficient, module, combination, general, economic future development.
In prior art, patent CN104526400A discloses a kind of screw clamping mechanism, comprises base, screw rod, clamp.By the rotation of screw rod, drive the clamp of screw rod upper end to add clamping of workpieces, play the effect of clamping.The advantage of this screw clamping mechanism prevents from clamping, produce larger active force, thus protection workpiece is not destroyed, and its shortcoming is, this clamp system structure is more complicated, also uses solder technology, once damage of components, is difficult to change.
Summary of the invention
The invention is intended to provide a kind of laborsaving, structure simple, the screw clamping mechanism of quick despatch.
For achieving the above object, base case of the present invention is: simple and easy screw clamping mechanism, comprise pedestal, described pedestal offers vertical hollow bulb, a clamp is provided with in described hollow bulb, the upper end of described clamp is fixed on the hollow bulb of pedestal by alignment pin, the lower end of described clamp is connected with the side of pedestal by spring, and described pedestal opposite side and described spring relative position are provided with a handle.
When adopting such scheme, by the rotation that handle is inside, handle compressing clamp, drives clamp clamping work pieces, plays the effect of clamping.Otherwise outside turning handle, now spring is to clamp elastic force, drives clamp to unclamp workpiece, realizes the quick despatch to workpiece.Moreover, because alignment pin is arranged on the one end near workpiece, analyze moment known, only need handle to a small gangs of power of clamping element just energy clamping work pieces, labour-saving effect can be reached like this.
Preferred version one: based on archives preferred, handle and the described pedestal of described handle are threaded connection.Dead load and temperature change little time, be threaded and can not automatically get loose, can not loosen after guaranteeing clamping element clamping work pieces.
Preferred version two: based on archives preferably another, the contact surface of described clamp and workpiece is arc surface, thus can not defective work piece during clamp clamping work pieces.
Accompanying drawing explanation
Fig. 1 is the structural representation of the simple and easy screw clamping mechanism embodiment of the present invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
As shown in Figure 1, the present invention includes pedestal 1, pedestal 1 offers vertical hollow bulb, a clamp 2 is provided with in hollow bulb, the upper end of clamp 2 is fixed on the hollow bulb of pedestal 1 by alignment pin 3, the lower end of described clamp 2 is connected with the side of pedestal 1 by spring 4, and pedestal 1 opposite side and spring 4 relative position are provided with a handle 5.
In the present invention, by the rotation that handle 5 is inside, clamp 2 is extruded, make clamp 2 upper end clamping work pieces, play clamping action.Otherwise outside turning handle 5, now spring 4 pairs of clamps 2 one elastic force, drive clamp 2 to unclamp workpiece, realize the quick despatch to workpiece.Moreover, because alignment pin 3 is arranged on the one end near workpiece, analyze moment known, only need handle 5 pairs of a small gangs of power of clamping element 2 just energy clamping work pieces, labour-saving effect can be reached like this.
