Description

Technical Field

[0001] The utility model relates to a precision machining technology and its use equipment, in particular to a tool positioning device suitable for a four-station circular oblique hole chamfering tool in a bench drill. Background Art

[0002] As far as the current manufacturing environment is concerned, the scope of use of special fixtures is still relatively wide; especially in the current manufacturing industry, the requirements for products are getting higher and higher. However, the structure of the product itself is also getting larger and more complex. Therefore, according to the actual requirements on the product drawings, we must choose the appropriate clamping method and the appropriate special fixture for cutting processing.

[0003] However, when we use the bench drill to perform chamfering of the oblique hole of the workpiece, we use the help of special fixtures for processing. Therefore, the fixture is an indispensable process equipment in mechanical processing. It is widely used and can play many roles, including ensuring stability and reliability during the processing.

[0004] In some processing occasions, there is a problem of uneven chamfering of inclined holes drilled by machine tools, and multiple processing parts need to be processed. At the same time, when drilling inclined holes on the machine tool, the depth of some inclined holes cannot meet the requirements of the drawings. Because when processing the inclined holes and the depth on the machine tool, the operator cannot see with the naked eye whether the depth of the inclined holes meets the requirements of the drawings. However, if the workpiece is taken off the machine tool to confirm, if it does not reach the depth of the drawing, the workpiece cannot be sent to the machine tool for a second processing, because there is a positioning error between the workpiece and the machine tool.

[0005] Therefore, it is necessary to provide a positioning device for the chamfering of circular inclined holes in four-station bench drilling to solve the above problems. Utility Model Content

[0008] A positioning device for a four-station circular oblique hole chamfering tool for a bench drill, comprising a bottom plate, on which four circular oblique hole chamfering stations are evenly arranged in an array;

[0009] The circumferential inclined hole chamfering station comprises an inclined hole chamfering panel, a loading bearing is arranged on the inclined hole chamfering panel, and a workpiece positioning pin hole and a locking hole are arranged on the loading bearing;

[0010] By adjusting the loading depth of the workpiece in the loading bearing, the outer end of the rear loading bearing is used as a limiting part for the inclined hole processing depth, forming a high-quality inclined hole processing depth control structure.

[0011] Furthermore, the four oblique hole chamfered panels are respectively recorded as panel A, panel B, panel C, and panel D; the inclination setting angles of panel A, panel B, panel C, and panel D are all different.

[0012] Furthermore, panel A, panel B, panel C, and panel D are respectively arranged on the bottom plate through inclined support block A, inclined support block B, inclined support block C, and inclined support block D.
