Abstract
The invention discloses a combined milling cutter, and belongs to the technical field of mechanical manufacture. The combined milling cutter comprises a cylindrical cutter holder which is fixedly connected to the radial direction of a conical handle; a groove for clamping a milling cutter is formed in the radial direction of the cutter holder; a positioning bolt for positioning the milling cutter is arranged on the cutter holder in a penetrating manner; an adjusting nut is connected to the outer wall of the lower part of the cutter holder by virtue of screw threads; and a positioning rod is arranged at the front part of the conical handle. According to the combined milling cutter, the adjusting nut is connected to the screw threads in the outer wall of the cutter holder, and the height of the milling cutter can be adjusted by virtue of the nut, so that the processes of assembling and disassembling the milling cutter can be reduced. The combined milling cutter is suitable for processing welding grooves with different calibers, 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 machinery manufacturing 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 6 as shown in Figure 5 and the joint portion of both drums 7, all will process corresponding bevel for welding by designing requirement, the bevel for welding bore of pipe joint 6 and the inwall of pipe have distance; The weld of pipe joint 6 as shown in Figure 6 itself and drum 7 is processed with bevel for welding 6a, and bevel for welding 6a directly can process with lathe, forms boss 6-1 at the weld of pipe joint 6; Its surface of drum 7 is as shown in Figure 7 arcwall face, its weld is processed with bevel for welding 7a, because bevel for welding 7a will corresponding to the bevel for welding 6a of pipe joint, and a boss 7-1 docked with boss 6-1 to be retained when processing bevel for welding 7a, so can only with milling machine to drum groove processing, its groove processing required precision is high, 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 being fixedly connected on taper shank radial direction, 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, and the front portion of described taper shank has backstay.
In combinations thereof milling cutter technical scheme, technical scheme can also be more specifically: described tool rest upper axial offers the screwed hole being communicated with described groove, installs described bolt in described screwed hole.
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.

Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the invention will be further described:
A kind of cutter block shown in Fig. 1, comprise the cylinder tool rest 4 being fixedly connected on taper shank 1 radial direction, as shown in Figure 2, Figure 3, Figure 4, 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, install 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.
Add man-hour, regulate the height of adjusting nut to locate milling cutter according to processing dimension, and tighten bolt by milling cutter positioning compression, after clamping completes, can groove processing be carried out.Tool rest outer wall thread place of the present invention is connected with adjusting nut, and by the height of the adjustable milling cutter of nut, reduce milling cutter dismounting operation, the bevel for welding of the different bore of applicable processing, structure is simple, easy accessibility, and machining accuracy is high, production efficiency is high.
Claims (2)
