Description

The structure-improved of work retainer

Technical field

The utility model, about a kind of accessory of vice clamp, is espespecially installed in the processing table of toolroom machine, according to this efficiency of lifting workpieces positioning clamping.

Background technology

Common metal machining is a kind of Precision Machining, when a large amount of work pieces process, first the vice of a piece-holder in the processing table of toolroom machine must be set machining benchmark point, the such as bottom of vice jaw is the machining benchmark point for Z-axis direction cutting, the fixed clamp block limit of vice jaw is then the machining benchmark point of Y-axis, then while carry out X-axis/Y-axis/Z-axis direction cutting operation, measure workpiece size, and this Y-axis, Z axis size can be used as the foundation of lower subjob cutting workpiece.Complete until this workpiece machining and unload after vice, being loaded on new workpiece, so repeating processing.

But, above-mentioned metal cutting process pattern, still be short of the machining benchmark point of X axis, therefore in order to the machining efficiency of lifting workpieces, human hair is just had to understand, as shown in Figure 9, No. I262836th, TaiWan, China patent of invention " work retainer preparation method ", before this patent, case is specially to provide the machining benchmark point of X axis, so that the machining efficiency of lifting workpieces.

But the existing work retainer 9 of case has two joints 91,92 and activity support rod 93 before above-mentioned patent, in spatially only having two frees degree, the joint 91 being wherein positioned at below provides Height Adjustment, and joint, the side of being located thereon 92 provides maintenance activity support rod 93 in the adjustment of level, separately this activity support rod 93 involves the mounting distance of this existing work retainer 9 relative to vice 8 side.Because this two joint 91,92 spacing commonly using work retainer 9 is fixing and cannot adjust, cause its adjustment height scope very little, if meet higher workpiece 81 cannot X axis machining benchmark location, or only can this workpiece 81 of contact lower position and lose X axis location accuracy.

Background technology: 8-vice; 81-workpiece; The existing work retainer of 9-; 91,92-joint; 93-activity support rod.

Utility model content

In view of the problem points of above-mentioned work retainer, so inventor of the present utility model and then motive are researched and developed and create a kind of structure-improved of new work retainer, therefore the main object of the utility model: be to provide increase one degree of freedom, to promote adjustment height scope, and provide the structure-improved of a kind of work retainer of machining benchmark point adjustment that is convenient, that make workpiece rapidly.

In order to aforesaid object can be reached, the technological means that the utility model uses includes: an expansion link group, the bottom of this expansion link group, top are respectively equipped with one first joint and a second joint place, and this first joint, spacing between second joint place are adjustable; One in conjunction with pedestal group, is hubbed at the first joint of this expansion link group; And a support rod group, be hubbed at the second joint place of this expansion link group.

This expansion link group above-mentioned is made up of bearing, once extension block, a lower seat and a coupling unit on extension block, on, and this coupling unit is made up of a screw and a nut, on this, extension block, downward-extension block are respectively equipped with one first chute and one second chute, and are stretched through after this first chute, the second chute by this screw and lock this nut again.

Above-mentioned on this extension block, downward-extension block be made up of a joint portion, an extension respectively, again on this extension block joint portion and on this bearing form this second joint place, the joint portion of this downward-extension block and this lower seat then form this first joint.

The extension of above-mentioned extension block on this from its joint portion 7 o'clock direction down integral type extend, and the extension of this downward-extension block extends from being directed upwardly integral type 1 o'clock of its joint portion.

The opposite face of above-mentioned extension block and this downward-extension block on this is provided with a detent, and the bottom of this detent establishes this first chute again, and separately this downward-extension block is to being then provided with a positioning block by detent.

This nut above-mentioned is ellipticity, and the top of the second chute of this downward-extension block is provided with one the 3rd chute, and the 3rd chute loads for this nut.

Therefore, above-mentioned technological means is used according to the utility model, there is the enhancement of following effect: the structure-improved of the utility model work retainer is adjustable by the spacing between one first joint of its expansion link group, second joint place, and then make this work retainer increase one degree of freedom, and increase the scope of its adjustment height, therefore the utility model structure is applicable to more greatly, the adjustment of the machining benchmark point of higher workpiece, and provide machining benchmark adjustment modes that is convenient, that make workpiece fast, and then promote its working (machining) efficiency.
