Description

Cutter block

Technical field

The utility model relates to Machining Technology field, especially a kind of cutter block for milling machine.

Background technology

In the production process of high-pressure boiler, need to be by drum together with pipeline welding, because the pressure of boiler is high, its pipeline also will bear corresponding high pressure, so pipe joint and drum welding is firmly whether particularly important, both joint portions of pipe joint as shown in Figure 67 and drum 8, all will process corresponding bevel for welding by designing requirement, and the bevel for welding bore of pipe joint 7 and the inwall of pipe have distance, the weld of pipe joint as shown in Figure 77 itself and drum 8 is processed with bevel for welding 7a, and bevel for welding 7a can directly process with lathe, forms boss 7-1 at the weld of pipe joint 7, drum 8 its surfaces are as shown in Figure 8 arcwall face, its weld is processed with bevel for welding 8a, because bevel for welding 8a will be corresponding to the bevel for welding 7a of pipe joint, and to retain a boss 8-1 who docks with boss 7-1 in the time of processing bevel for welding 8a, so can only be with milling machine to drum groove processing, its groove processing required precision is high, when the excessive and milling cutter of the width dimensions of bevel for welding to be processed once complete man-hour that adds that does not become whole bevel for welding, will shut down and again adjust milling cutter size, clamping carries out secondary operations, processing is got up more complicated and loaded down with trivial details, and existing machining accuracy is low does not often reach requirement, so be badly in need of a kind of cutter block of simple and convenient and practical special groove.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of cutter block, when this cutter block can solve processing drum bevel for welding, more complicated and loaded down with trivial details, and machining accuracy is low does not reach requirement, causes the problem that productivity ratio is low.

In order to address the above problem, the technical scheme that the utility model adopts is: this cutter block, comprise two cylinder tool rests that are vertically connected in taper shank sidewall, described tool rest radially has the groove of clamping milling cutter, the bolt that is coated with location milling cutter on described tool rest, the bottom outer wall of described tool rest has been threaded connection adjusting nut; The front portion of described taper shank has backstay, on described backstay, has extended radially out scale bar, on described scale bar, is carved with size.

In combinations thereof milling cutter technical scheme, technical scheme can also be more specifically: described tool rest is symmetricly set in the both sides of taper shank middle front part, and described tool rest upper axial offers the screwed hole that is communicated with described groove, installs described bolt in described screwed hole.

Further: described scale bar is 9mm～12mm apart from the horizontal range of milling cutter end, and described scale bar is two, is symmetricly set in the both sides of taper shank, vertical with described tool rest.

Owing to having adopted technique scheme, the utility model compared with prior art has following beneficial effect:

1, simple in structure, the easy accessibility of the utility model, machining accuracy is high, production efficiency is high.

2, tool rest outer wall thread of the present utility model place is connected with adjusting nut, by the height of the adjustable milling cutter of adjusting nut, is applicable to the bevel for welding of the different bores of processing, reduces milling cutter dismounting operation, enhances productivity.

3, tool rest of the present utility model arranges two, can, according to the size of bevel for welding width to be processed, adjust respectively adjusting nut height dimension, makes its clamping once just can complete the processing of bevel for welding.

4, the utility model is provided with scale bar on taper shank, adds the size in man-hour in the process of processing with regard to observable, ensures the precision of processing.
