Abstract

The utility model discloses a three-way and four-way special clamping mould, which consists of an upper mould and a lower mould and is characterized in that: the upper mould is composed of an upper semi-cylinder with an upper semi-convex edge; the lower mould is composed of a lower semi-cylinder with a lower semi-convex edge; the corresponding positions on the central parts of the inner side planes of the upper and lower semi-cylinders are respectively provided with a V-shaped groove with an included angle of 90 degrees; and when then inner side planes of the upper and lower semi-cylinders are mutually superposed, the two V-shaped grooves form a rectangular or square clamping square hole. The special clamping mould disclosed by the utility model has the advantages of simple structure, convenient use, capability of guaranteeing three-way and four-way parts and other workpieces with irregular shapes to meet the processing requirements after being processed and realizing the aim of clamping on a three-jaw of a machine tool conveniently; and the special clamping mould also reduces the process for processing workpieces with irregular shapes, greatly improves the working efficiency, reduces human labor and is an ideal three-way and four-way special clamping mould.

Description

Threeway, the special-purpose clamping mold of four-way

Technical field

The utility model relates to a kind of fixture clamping fixture, and the special-purpose clamping mold of particularly a kind of threeway, four-way is applicable to the batch machining of threeway on the hydrogen manufacturing project, four-way spare, and the processing and the reparation of the irregular workpiece of profile such as various small-sized rectangle, square.

Background technology

At present, in the machined field, if the irregular workpiece of some profiles is processed and repaired, then can only clamping workpiece processed on the four paws of lathe, repair, operation be very loaded down with trivial details, has increased the work of working time and manpower greatly.

The utility model content

The purpose of the utility model is: design a kind of threeway, the special-purpose clamping mold of four-way; This mold can either guarantee that threeway, four-way spare and the irregular workpiece of other profile reach technological requirement after processing, can be implemented in the purpose of convenient mounting and clamping on the three-jaw of lathe again; Reduce the operation of the irregular workpiece of processing profile, improved operating efficiency greatly, reduced the manpower work.

The purpose of the utility model can realize through following technical proposals:

This threeway, the special-purpose clamping mold of four-way; Form by last tire and following tire; It is characterized in that: go up tire and constitute by first cylinder that the front portion has first convex edge; Following tire is made up of second cylinder that the front portion has second convex edge, and it is 90 ° v-depression that the corresponding position, middle part of first cylinder and second cylinder inner side plane respectively is provided with an angle; When the inner side plane of first cylinder and second cylinder overlapped, two v-depression formed shapes were rectangle or foursquare clamping square hole.

The summit of the v-depression at first cylinder inner side plane middle part of the utility model and the tangent distance of first convex edge are 20mm; The summit of the v-depression at second cylinder inner side plane middle part and the tangent distance of second convex edge are 20mm.

The utility model has the advantages that: simple in structure, easy to use; Can either guarantee that threeway, four-way spare and the irregular workpiece of other profile reach technological requirement after processing, can be implemented in the purpose of convenient mounting and clamping on the three-jaw of lathe again; Having reduced the operation of the irregular workpiece of processing profile, improved operating efficiency greatly, reduced the manpower work, is the special-purpose clamping mold of a kind of desirable threeway, four-way.

The specific embodiment

Like Fig. 1---shown in 7; This threeway, the special-purpose clamping mold of four-way; Form by last tire and following tire; It is characterized in that: go up tire and be made up of first cylinder 2 that the front portion has first convex edge 1, following tire is made up of second cylinder 4 that the front portion has second convex edge 5, and it is 90 ° v-depression 3 that the corresponding position, middle part of first cylinder 2 and second cylinder 4 inner side plane respectively is provided with an angle; When the inner side plane of first cylinder 2 and second cylinder 4 overlapped, two v-depression 3 formed shapes were rectangle or foursquare clamping square hole 6.The summit of the v-depression 3 at first cylinder 2 inner side plane middle part and the tangent distance of first convex edge 1 are 20mm; The summit of the v-depression 3 at second cylinder 4 inner side plane middle part and the tangent distance of second convex edge 5 are 20mm.

The special-purpose clamping mold of this threeway, four-way in use, at first, with threeway, four-way spare or the irregular clamping workpiece of other profile in the clamping square hole 6 of this mold; Then, the direct clamping in the cylindrical rear portion of notch cuttype of last tire and play tire composition on the three-jaw of lathe, has promptly been realized the purpose of convenient mounting and clamping on the three-jaw of lathe, and then can processed and repair the irregular workpiece of profile through the three-jaw of lathe.
