Description
Technical field
The present invention relates to frock clamp, relating to a kind of frock clamp for processing H type lock valve valve body or rather.
Background technology
Lock valve is applied to the valve in heating, supply line system.The valve body of lock valve is threeway.H type lock valve valve body is formed by connecting, in H-shaped shape by two triple-valve bodies.In the manufacture process of H type lock valve valve body, the mouth of pipe of three passages to each valve body is needed to carry out machined.H type lock valve valve body is processed with its special frock clamp, prior art comprise two dog chucks, two claw assemblies and the edge core for placing product for the frock clamp processing H type lock valve valve body.Two described claw assemblies are located on two described dog chucks, and described edge core is located on two described claw assemblies.During use, H type lock valve valve body is arranged on described edge core.The frock clamp of this kind of prior art once assembles the mouth of pipe of the passage can only processing a valve body, and whole valve body one has six mouths of pipe, therefore need assembling six times, just can complete the processing of a product, working (machining) efficiency is quite low, and dismounting dress comparatively affects again the machining accuracy of product.
Summary of the invention
The technical problem to be solved in the present invention is, provides a kind of working (machining) efficiency that can improve product can improve again the frock clamp for processing H type lock valve valve body of the machining accuracy of product.
Technical solution of the present invention is, a kind of frock clamp for processing H type lock valve valve body with following structure is provided, comprise two dog chucks, two claw assemblies and the edge core assembly for product clamping, two described claw assemblies are located on two described dog chucks, and described edge core assembly is located on two described claw assemblies; Two pawl bodies of two claw assemblies are provided with slideway, and described edge core assembly is slidably fitted in described slideway; Positioner is provided with between described edge core assembly and two described pawl bodies.
After adopting above structure, the frock clamp for processing H type lock valve valve body of the present invention, compared with prior art, has the following advantages:
Because two pawl bodies of two claw assemblies of the frock clamp for processing H type lock valve valve body of the present invention are provided with slideway, described edge core assembly is slidably fitted in described slideway; Positioner is provided with between described edge core assembly and two described pawl bodies; Like this when processing the mouth of pipe of two passages of the same side, as long as clamping once, as long as so six mouth of pipe clampings just can for three times, when processing the mouth of pipe of two passages of the same side, process what a mouth of pipe, then slide edge core assembly, slides into certain position and position, the reprocessing another one mouth of pipe, very easy to use.Therefore, frock clamp of the present invention can improve the working (machining) efficiency of product; Clamping times decreases, and also can improve the machining accuracy of product.
As a modification of the present invention, described edge core assembly comprises the first edge core and the second edge core, forms the space being used for product clamping between the first described edge core and the second edge core.After adopting this kind of structure, during use, product clip is held between the first edge core and the second edge core.
Improve as another kind of the present invention, described positioner comprises the positioning ejection pin assemblies be located on the first edge core and the second edge core and the locating hole matched with described positioning ejection pin assemblies be located at bottom described slideway.After adopting this kind of structure, described positioning ejection pin assemblies is embedded in described locating hole, carries out spacing to positioning ejection pin assemblies, thus carries out spacing to the first edge core and the second edge core.
Also have a kind of improvement as of the present invention, described positioning ejection pin assemblies comprises position and lock screw, stage clip and positioning ejection pin; Described first edge core and the second edge core are equipped with the passage for accommodating pin assembly; In the lower end that described positioning ejection pin is slidably fitted in the passage of described first edge core or described second inlay in the lower end of the passage of core; Described position and lock screw screws in the upper end of the passage of the second edge core in the upper end of the passage of the described first edge core or described; Described stage clip is located between described position and lock screw and positioning ejection pin, and the lower end of described stage clip is tightly linked in outside the upper end of described positioning ejection pin.After adopting this kind of structure, when retainer spring assembly does not also arrive locating hole, stage clip is compressive state, and when retainer spring assembly arrives locating hole, described positioning ejection pin springs in described locating hole, thus can effectively position.
Also have a kind of improvement as of the present invention, the lower end of described positioning ejection pin is semicircle.After adopting this kind of structure, the lower end of described positioning ejection pin is semicircle, effectively can play the effect of guiding when positioning ejection pin departs from locating hole.
Also have a kind of improvement as of the present invention, be equipped with projection on the outer wall of the first described edge core and on the outer wall of the second described edge core, the relative two side of described slideway is equipped with chute; Projection on the first described edge core and the projection on the second edge core are slidably fitted in two chutes correspondingly.After adopting this kind of structure, described projection, along slide, coordinates closely, can effective control accuracy.
Also have a kind of improvement as of the present invention, the shape of cross section of described projection is horizontal "T"-shaped, and with the mating shapes of described projection, the shape of cross section of described chute also be the "T"-shaped of transverse direction.After adopting this kind of structure, prevent the first described edge core and the second edge core from departing from slideway.
Also have a kind of improvement as of the present invention, the outer wall of described projection is provided with many raised lines, and the sidewall of described chute is provided with multiple stria, and described multiple raised lines are engaged in described multiple strias correspondingly.After adopting this kind of structure, described raised line and chute are coordinated more tight, locate more accurate up and down, thus make dirty also can not remaining in groove.
