Abstract
The utility model relates to a punching clamp capable of guaranteeing concentricity. The punching clamp capable of guaranteeing concentricity comprises a first clamp body, a second clamp body, an adapting piece and a locating block. The first clamp body and the second clamp body are fixedly connected through the adapting piece. A first fixing round groove is formed in the center of the end face of one side of the first clamp body, wherein the side of the first clamp body is opposite to the second clamp body. A square groove and a second fixing round groove are sequentially formed in the end face of one side of the second clamp body, wherein the side of the second clamp body is opposite to the first clamp body. The second fixing round groove and the first round groove are concentric. The locating block is arranged on the outer end face of the second clamp body. A first locating hole is formed in the center of the locating block, and the first locating hole and the second fixing round groove are concentric. Second locating holes are formed in the outer end face of the locating block, and are distributed in a circular array mode. The second locating holes are communicated with the second fixing round groove.

Along with progress and the development of production technology, the structure of machine components is more diversified, and the required precision of machine components is also higher.Now process a kind of workpiece as shown in Figure 1, it need to be at centre bore of the face of cylinder of workpiece processing, then on the face of cylinder and square face, process respectively the circular hole that one group of circular array distributes, and need to guarantee the concentricity of two groups of circular holes and centre bore, such work belongs to irregular workpiece, is fixed up not to be very convenient.Existing processing method generally all is to use first universal fixturing that workpiece is fixed, then the hole on the processing column face, then reprocess the hole on the square face, the hole can be processed although do like this, but the concentricity of two groups of circular holes and centre bore can not guarantee, can not satisfy the demand of production, and working (machining) efficiency is low, inapplicable batch production.
The utility model content
The utility model purpose is the perforating clamp that the high assurance concentricity of a kind of two groups of circular holes that can guarantee to process on the workpiece and the concentricity between the centre bore and working (machining) efficiency is provided in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model be: a kind of perforating clamp that guarantees concentricity comprises the first clamp body, the second clamp body, connector and locating piece; Be fixedly connected by connector between described the first clamp body and the second clamp body; Described the first clamp body and the second clamp body side end face central authorities in opposite directions have the first fixing circular groove; Described the second clamp body and the first clamp body have fixedly circular groove of square groove and second on the side end face in opposite directions successively; Described second fixedly circular groove fixedly circular groove is concentric with first; The outer face of described the second clamp body is provided with locating piece; Described locating piece central authorities have and the second fixing concentric the first locating hole of circular groove; The outer face of described locating piece has centered by the first locating hole, the second locating hole that circular array distributes; Described the second locating hole with second fixedly circular groove communicate; Have centered by the first locating hole the 3rd locating hole that circular array distributes on the outer face of described the second clamp body; Described the 3rd locating hole communicates with square groove.
Preferably, described locating piece is cylindrical.
Preferably, described connector is bolt.
Preferably, described bolt is arranged with two.
Because the utilization of technique scheme, the utility model compared with prior art has following advantages:
A kind of perforating clamp that guarantees concentricity of the utility model scheme, it is simple to operate, and is easy to use, two groups of circular holes that can guarantee to process on the workpiece and the concentricity between the centre bore, and working (machining) efficiency is high, is applicable to batch machining.
