Abstract

The utility model discloses a general tool rest with variable diameters, belongs to the machining equipment field, and aims at solving the problems that due to the fact that a tool clamping position of a tool rest of an existing CK6163 numerically-controlled machine tool is narrow, a long tool cannot be clamped, as a result, a deep bore cannot be machined; due to the influence of a stroke and a high carriage plate center, when a small inner bore is machined, the stroke is exceeded, and the length dimension of a tool for outer diameter machining is limited; and meanwhile, the adaptability of the tool is poor. A plurality of first threaded holes are formed in an upper tool rest body in the circumferential direction. A first locating screw is arranged in each first threaded hole. The general reduction tool rest further comprises a second tool rest body. A U-shaped groove is formed in the second tool rest body. A second tool rest fixing plate is arranged on the other side, opposite to a U-shaped opening, of the second tool rest body. The first locating screws penetrate through the first threaded holes and fix the second tool rest fixing plate between the upper tool rest body and a lower tool rest body. A plurality of second threaded holes are formed in the second tool rest body in the vertical direction. Locating screws are arranged in the second threaded holes. The general reduction tool rest is used for fixing tools of a machine tool.

Description

A kind of general reducing knife rest

Technical field

The utility model relates to a kind of reducing knife rest, belongs to the machining equipment field.

Background technology

Existing C K6163 Digit Control Machine Tool, because knife rest folder cutter place is narrower, the maximum clamping thickness of knife bar only is 50mm, the diameter of clamping knife bar is very limited, and then the working depth of limiting holes greatly, because the knife bar diameter increases, then rigidity is more good, it is longer that knife bar just can design, and machinable hole is just more dark, causes in existing 300MW, 600MW and the 1000MW Steam Turbine's Main Vaper Valve dish degree of depth can't process greater than the deep hole of 430mm at all; CK6163 Digit Control Machine Tool processing internal diameter is less and thickness little but during the bigger workpiece of diameter, owing to be subjected to the high influence of stroke and planker center, and the problem that to cause the excess of stroke and cutter respectively easily owing to fall short of limited etc., simultaneously, the adaptability of cutter is relatively poor.

The utility model content

The utility model is for solving existing CK6163 Digit Control Machine Tool owing to knife rest folder cutter place is narrower, can't cause to process darker hole than long cutter by clamping, owing to the little endoporus excess of stroke of processing that caused by the high influence of stroke and planker center is size-constrained with processing external diameter tool length, simultaneously, the relatively poor problem of the adaptability of cutter.

Provide a kind of general reducing knife rest for solving the problems of the technologies described above, described knife rest comprises first knife rest,

The first knife rest bag

Draw together lower slide, upper tool post, first dog screw and link, upper tool post be arranged on lower slide directly over, the centre position of upper tool post upper surface has through hole and link and passes through hole upper tool post and lower slide are fixed together, along the circumferential direction have a plurality of first screwed holes on the described upper tool post, a plurality of first screwed holes all vertically run through on upper tool post and each first screwed hole and are provided with first dog screw, described knife rest also comprises second knife rest, the perforation and the opening direction that have U-lag and U-lag on second knife rest are horizontal direction, to be that the second knife rest fixed head and the second knife rest fixed head are all or part of be arranged between upper tool post and the lower slide opposite side relative with the U-shaped opening on second knife rest, first dog screw passes first screwed hole and the second knife rest fixed head is fixed between upper tool post and the lower slide, vertically have a plurality of second screwed holes on the end in the two ends about the U-lag on described second knife rest, all screwed a dog screw on each second screwed hole.

The utility model compared with prior art has following beneficial effect:

1, the utility model is by carrying out machining in the U-lag of cutter clamping on second knife rest, but increased the diameter of clamping knife bar accordingly, but the therefore longer knife bar of clamping realizes that the degree of depth is greater than effective processing in the hole of 430mm.

2, the utility model adds second knife rest between cutter and first knife rest, and original numerically-controlled slide is increased along the movable stroke of X-axis positive direction, therefore can solve the excess of stroke problem in the less endoporus processing effectively.

3, the utility model is in that processing thickness is little but during the workpiece that diameter is bigger, adopt positive clamping, a part that makes second knife rest reaches the outside of first knife rest along Z axle positive direction, has increased the length of knife rest accordingly, the limited problem of tool length in the time of therefore can effectively solving the processing external diameter.

4, the utility model can be according to the shape and size of workpiece to be machined, second knife rest can manufacture different shape and size, by changing the second different knife rests, improved the adaptability of numerically-controlled slide, for example: second knife rest can be made into the different multiple knife rest of relative altitude of the second knife rest fixed head and U-lag, use the second different knife rest of relative altitude of the second knife rest fixed head and U-lag can change the vertical height of cutter, improved the adaptability of numerically-controlled slide.
