Abstract
Disclosed is a multifunctional combination cutting tool. An alloy bit is arranged at the head of a tool body, a radial through groove is arranged on the tool body behind the alloy bit, an orifice chamfer tool is mounted in the through groove, an upper chamfer and a lower chamfer are arranged at one extending end of the chamfer tool, and a cutting edge is arranged on a chamfer face. A stepped face is arranged on the tool body at the rear end of the through groove by being spaced at a certain distance, a facing blade is mounted at the position of the stepped face, and the certain distance is larger than the depth of a hole to be machined. A central hole extending to the through groove from back is arranged in the tool body, a lifting pin is mounted in the central hole, the head of the lifting pin is abutted to an inclined groove of the orifice chamfer tool, a compression spring is mounted at the rear end of the lifting pin, and a limit pin is mounted at the rear end of the compression spring and limited by a plug arranged at a central orifice. By the aid of the multifunctional combination cutting tool, broaching, orifice chamfering and facing can be completed by means of one-step clamping, repeated clamping time and machining time are shortened, machining efficiency is improved by two to three times, and the machining cost of products is reduced.
Description
Technical field
It is the compound tool of one that the utility model relates to reaming, chamfering, spot facing function.
Background technology
At present, there is the processing of some through holes to relate to boring, reaming, aperture two chamfers, aperture spot facing.Boring, reaming, aperture two chamfers, aperture spot facing all substep carry out, and need a plurality of cutters to accomplish corresponding processing, and not only working (machining) efficiency is on the low side, also causes the waste of material resources, manpower.
For example, the processing of the bearing block of 485 vehicle bridge divides four step processing (boring, reaming, spot-facing mouth plane, chamfering), and working (machining) efficiency is on the low side, causes the waste of material resources, manpower.
Summary of the invention
In order to improve working (machining) efficiency, reduce the processing cost of product, the utility model proposes a kind of multi-functional compound tool.
The technical scheme of the utility model is: a kind of multi-functional compound tool; Head at cutter hub is provided with alloy bit; It is characterized in that: on the cutter hub of alloy bit back, be provided with radially through slot; The aperture rose reamer is housed in the through slot, and the overhanging end of rose reamer is provided with chamfering up and down, and fillet surface is a blade; On the cutter hub of through slot rear end, keep at a certain distance away and be provided with step surface, the flat blade of ream is equipped with at the step surface place, and described certain distance is greater than the degree of depth in hole to be processed; Be provided with in the cutter hub from after extend to the centre bore of through slot; An ejector pin is contained in the centre bore, and the ejector pin head withstands on the skewed slot of aperture rose reamer, and the compression spring is equipped with in the ejector pin rear end; The compression spring rear end is equipped with spacer pin, and spacer pin is spacing through the plug that center port is provided with.
Beneficial effect: the cutter hub of the utility model is provided with drill bit, rose reamer, the flat blade of ream; A clamping just can be accomplished reaming, aperture chamfering, spot facing, because three functions of collection are one; Reduced the time of repeated clamping; Shortened process time, working (machining) efficiency has improved 2～3 times, has reduced the processing cost of product simultaneously.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As shown in Figure 1; It is following to further describe the utility model: a kind of multi-functional compound tool; Head at cutter hub 1 is provided with alloy bit 2, on the cutter hub of alloy bit back, is provided with radially through slot, and aperture rose reamer 3 is housed in the through slot; The overhanging end of rose reamer is provided with chamfering up and down, and fillet surface 3a is a blade; On the cutter hub 1 of through slot rear end, keep at a certain distance away and be provided with step surface, the flat blade 8 of ream is equipped with at the step surface place, and described certain distance is greater than the degree of depth in hole to be processed; Be provided with in the cutter hub 1 from after extend to the centre bore of through slot; An ejector pin 4 is contained in the centre bore, and the ejector pin head withstands on the skewed slot of aperture rose reamer, and compression spring 5 is equipped with in ejector pin 4 rear ends; Spacer pin 6 is equipped with in compression spring 5 rear ends, and spacer pin 6 is spacing through the plug 7 that center port is provided with.
The process principle of multi-functional compound tool as shown in Figure 1: cutter moves downward, and realizes reaming; Move downward fast, the aperture rose reamer is got in the cutter hub by workpiece and (is overcome spring force), and ream is put down blade near the aperture, then spot facing; Upwards griffe tool, realize the aperture chamfering, upwards griffe tool fast, the aperture rose reamer is got in the cutter hub by workpiece and (is overcome spring force), and the cutter return machines.
