In order to simplify the operating procedure, improve production efficiency and reduction in production cost, the utility model provides a frock clamp.

In order to realize the purpose, the utility model discloses a technical scheme as follows:

a tool clamp comprises an angle iron clamping base and a positioning part arranged on the upper end face of the angle iron clamping base; the upper end face of the angle iron clamping base is also provided with two rotary pressing parts; the two rotary pressing parts are both composed of bolts and rotatable pressing plates; the connecting lines of the central points of the two bolts and the three points of the central point of the positioning part form an isosceles triangle.

Preferably, the upper end face of the angle iron clamping base is further provided with an installation screw hole.

Preferably, the positioning part is a positioning bolt.

Preferably, a threaded through hole corresponding to the mounting screw hole is formed in the center of the positioning bolt; the threaded through hole and the mounting screw hole are coaxially arranged.

Preferably, a positioning base is arranged between the upper end face of the angle iron clamping base and the positioning part.

Preferably, two product positioning pin holes are formed in the length direction of the upper end face of the positioning base; the two product positioning pin holes are arranged on two sides corresponding to the positioning parts.

Preferably, the product locating pin hole is provided with an internal thread.

Preferably, a nut is arranged on the bolt.

Preferably, the length of the positioning base in the vertical direction is the same as the length of the nut in the vertical direction.

The utility model has the advantages that:

the utility model discloses a frock clamp confirms the product position through location portion, need not rectify each product, has simplified the operating procedure, has improved work efficiency, and frock clamp's simple structure, installation are convenient, low cost, are applicable to the inclined hole processing of special construction product, can effectual assurance product machining precision, in machining process, have very big industry popularization and application and worth.

Detailed Description

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are for purposes of illustration only and are not intended to limit the scope of the present invention.

As shown in fig. 1, a tooling clamp comprises an angle iron clamping base 1 and a positioning part 3 arranged on the upper end surface of the angle iron clamping base; the upper end surface of the angle iron clamping base is also provided with two rotary pressing parts; the two rotary pressing parts are both composed of bolts and a rotatable pressing plate 5; the central points of the two bolts and the three-point connecting line of the central point of the positioning part form an isosceles triangle. The positioning part is used for positioning a product to be processed, and the rotary pressing part is used for fixing the product and fixing and dismounting the product conveniently through the rotary pressing plate.

As a further improvement, the upper end face of the angle iron clamping base is also provided with an installation screw hole.

As a further improvement, the positioning portion 3 is a positioning bolt.

As a further improvement, as shown in fig. 2, a threaded through hole corresponding to the mounting screw hole is arranged at the center of the positioning bolt; the threaded through hole and the mounting screw hole are coaxially arranged.

As a further improvement, a positioning base 2 is arranged between the upper end surface of the angle iron clamping base and the positioning part 3.

As a further improvement, two product positioning pin holes 4 are arranged in the length direction of the upper end surface of the positioning base 2; two product registration pin holes 4 are provided on both sides corresponding to the registration portions 3. The purpose of the product positioning pin is to calibrate and position a product.

As a further improvement, the product dowel hole 4 is provided with an internal thread. Wherein the provision of the internal thread serves to fix the product on the positioning device.

As a further improvement, the bolt is provided with a nut 6. Wherein, the purpose of setting up the nut is in order to guarantee that the product of processing is on the coplanar.

As a further modification, as shown in fig. 3, the length of the positioning base 2 in the vertical direction is the same as the length of the nut 6 in the vertical direction. The length of the positioning base in the vertical direction is the same as the length of the nut in the vertical direction, and therefore the products needing to be machined are guaranteed to be on the same plane.
