Description

Circular workpiece tool clamp

Technical Field

The utility model relates to the field of tool fixtures in machine tool machining, in particular to a tool fixture for a circular workpiece.

Background

The circular workpiece is a common workpiece type in mechanical equipment, and is easy to roll due to the cylindrical shape, so that the circular workpiece is difficult to fix during machining. For a round workpiece, generally, when a machine tool is used for machining, the adopted fixing method is to directly fix the workpiece on a working table of the machine tool, and the periphery of the round workpiece is assisted and fixed by other iron pieces with the height lower than the machining surface of the round workpiece, so that the round workpiece can be stably fixed on the machine tool. When the method is used, the working efficiency of the upper machine fixing and the lower machine dismounting of the circular workpiece is low, and the inconvenience is brought when the method is used, so that the production cost is increased. If the auxiliary fixation of an iron piece is not adopted, the workpiece can move or directly fly out of the working table surface under the action of the cutting force of the machining tool, and the quality problem and the potential safety hazard can be caused.

The technical scheme adopted by the utility model is as follows:

the utility model provides a circular workpiece frock clamp, a fixture pedestal has, a plurality of frock holes of one row have been seted up on the upper surface of fixture pedestal, the frock hole is at least including the circular port of bunching, the part of the circular port of bunching overlaps each other, make the pore wall part intercommunication of adjacent circular port, perhaps the circular port of bunching is link up by a horizontal slot hole and makes its intercommunication each other, set up one row and the screw hole of frock hole one-to-one in the side of fixture pedestal, the screw hole inwards communicates with the lateral wall of frock hole, threaded hole is equipped with fastening bolt, fastening bolt passes the screw hole and reachs in the frock hole, press from both sides tightly the downthehole circular workpiece of frock.

As a further improvement of the above technical solution:

when the parts of the serial circular holes are mutually overlapped to make the hole walls of the adjacent circular holes partially communicated, the serial circular holes are in a multi-joint gourd-shaped shape when viewed from the top.

When the strings of circular holes are communicated with each other by a transverse long hole, the sugarcoated haws are in a multi-section shape in a top view.

The frock hole is including the circular port and the independent circular port of bunching, and the size of all circular ports increases progressively.

The tool hole comprises two groups of serial circular holes and more than one independent circular hole.

When the apertures of the threaded holes in the row are the same, one fastening bolt corresponds to all the threaded holes.

When the aperture sizes of the row of threaded holes are different, the fastening bolts correspond to the threaded holes one to one or correspond to partial threaded holes.

Two ends of the clamp base are fixed on the machine tool through the pressing mechanism.

The clamp base is a rectangular base body with six surfaces.

The utility model has the following beneficial effects:

according to the utility model, the upper surface of the clamp base is provided with the row of the plurality of tool holes, the fastening bolts are arranged in the threaded holes on the side surface of the clamp base, and the round workpieces in the tool holes are clamped through the fastening bolts, so that the operation of loading and unloading is convenient, the clamping is stable and reliable, the multipurpose clamp can be realized, and the cost is saved. The tool holes are formed in a string, the parts of the string of circular holes are mutually overlapped, or the string of circular holes are communicated through a transverse long hole, so that the clamping of circular workpieces with various specifications can be met, the space of the clamp base can be saved, the workpieces with more sizes can be accommodated, meanwhile, the consumed materials of the clamp base can be saved due to the string of circular holes, and the material cost is saved.

Detailed Description

The following describes embodiments of the present invention with reference to the drawings.

As shown in fig. 1 to 3, the circular workpiece fixture according to the present invention includes a fixture base 1, and the fixture base 1 is a rectangular base having six surfaces. A plurality of tool holes 2 are formed in one row on the upper surface of the clamp base 1, the tool holes 2 are stringed round holes, or the tool holes 2 comprise stringed round holes and independent round holes. The parts of the serial round holes are mutually overlapped, so that the hole walls of the adjacent round holes are partially communicated, and the serial round holes are in a multi-joint gourd-shaped overlooking view. Or the serial round holes are communicated with each other by a transverse long hole, and the sugarcoated haws are in a multi-section shape when viewed from top. As an embodiment, the sizes of all round holes are increased in sequence, and the clamping of round workpieces with various specifications is met. The side of the clamp base 1 is provided with a row of threaded holes 3 which correspond to the tool holes 2 one by one, and the threaded holes 3 are communicated with the side walls of the tool holes 2 inwards. The fastening bolt 4 can be installed in the threaded hole 3, and the fastening bolt 4 penetrates through the threaded hole 3 to reach the tool hole 2 to clamp a round workpiece in the tool hole 2. When the hole diameters of the row of threaded holes 3 are the same, one fastening bolt 4 can correspond to all the threaded holes 3, and when the hole diameters of the row of threaded holes 3 are different, the fastening bolts 4 correspond to the threaded holes 3 one to one or correspond to partial threaded holes 3. The two ends of the clamp base 1 are fixed on a machine tool through the pressing mechanisms, and after the round workpiece is placed into the tool hole 2 on the clamp base 1, the round workpiece is fixedly clamped through the fastening bolt 4, and then machining operation is carried out.
