Abstract
The invention discloses a combined milling cutter, and belongs to the technical field of mechanical processing. The combined milling cutter comprises two cylindrical cutter holders which are vertically connected to the side wall of a conical handle; a groove for clamping a milling cutter is formed in the radial direction of each cutter holder; a positioning bolt for positioning the milling cutter is arranged on each cutter holder in a penetrating manner; an adjusting nut is connected to the outer wall of the lower part of each cutter holder by virtue of screw threads; a positioning rod is arranged at the front part of the conical handle; a ruler rod radially extends from the positioning rod, and scales are marked on the ruler rod. According to the combined milling cutter, the two cutter holders are arranged, the adjusting nuts are connected to the screw threads in the outer walls of the milling cutters, and the heights of two milling cutters can be respectively adjusted by virtue of the nuts, so that the aim of once grooving can be achieved, and the processes of assembling and disassembling milling cutters can be reduced. The combined miller is suitable for processing welding grooves with different calibers, can be used for observing processing sizes in the processing process to guarantee the processing accuracy since the ruler rod is arranged on the conical handle, and is simple in structure, convenient to assemble and disassemble, high in processing accuracy and high in production efficiency.
Description
Technical field
The present invention 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 drum together with pipeline welding, because the pressure of boiler is high, its pipeline also will bear corresponding high pressure, so pipe joint weld with drum whether firm particularly important, pipe joint 7 as shown in Figure 6 and the joint portion of both drums 8, all will process corresponding bevel for welding by designing requirement, the bevel for welding bore of pipe joint 7 and the inwall of pipe have distance, the weld of pipe joint 7 as shown in Figure 7 itself and drum 8 is processed with bevel for welding 7a, and bevel for welding 7a directly can process with lathe, forms boss 7-1 at the weld of pipe joint 7, its surface of drum 8 is as shown in Figure 8 arcwall face, its weld is processed with bevel for welding 8a, because bevel for welding 8a will corresponding to the bevel for welding 7a of pipe joint, and a boss 8-1 docked with boss 7-1 to be retained when processing bevel for welding 8a, so can only 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 can not add 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.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of cutter block, and when this cutter block can solve processing drum bevel for welding, more complicated and loaded down with trivial details, machining accuracy is low does not reach requirement, causes the problem that productivity ratio is low.
In order to solve the problem, the technical solution adopted in the present invention is: this cutter block, comprise the cylinder tool rest that two are vertically connected to taper shank sidewall, described tool rest radial direction has the groove of clamping milling cutter, described tool rest is coated with the bolt of location milling cutter, the bottom outer wall of described tool rest has been threaded connection adjusting nut; The front portion of described taper shank has backstay, and described backstay has extended radially out scale bar, and 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 being communicated with described groove, installs described bolt in described screwed hole.
Further: the horizontal range of described scale bar distance milling cutter end is 9mm ~ 12 mm, and described scale bar is two, is symmetricly set in the both sides of taper shank, vertical with described tool rest.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, simple, the easy accessibility of structure of the present invention, machining accuracy is high, production efficiency is high.
2, tool rest outer wall thread place of the present invention 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 bore of processing, reduces milling cutter dismounting operation, enhances productivity.
3, tool rest of the present invention arranges two, according to the size of bevel for welding width to be processed, can adjust adjusting nut height dimension respectively, make its clamping once just can complete the processing of bevel for welding.
4, the present invention 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.

Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the invention will be further described:
Embodiment one
Cutter block shown in Fig. 1, Fig. 2, comprise the cylinder tool rest 4 that two are vertically connected to taper shank 1 middle front part sidewall, tool rest 4 is symmetricly set in the both sides of taper shank 1, as shown in Fig. 3, Fig. 4, Fig. 5, tool rest 4 radial direction has the groove of clamping milling cutter 2, tool rest 4 upper axial offers the screwed hole being communicated in this groove, location milling cutter 2, installs bolt 5 in this screwed hole; The bottom outer wall of tool rest 4 has been threaded connection adjusting nut 3, and the front portion of taper shank 1 has backstay 1-1; Backstay 1-1 extends radially out the both sides that two scale bar 6, two scale bars 6 being carved with size are symmetricly set in taper shank 1, vertical with tool rest 4, scale bar 6 is 9mm apart from the horizontal range of milling cutter 2 end.
Embodiment two
Scale bar 6 is 12 mm apart from the horizontal range of milling cutter 2 end, and all the other are all identical with embodiment one.
