Abstract
The utility model relates to a three-in-one special cutter, which comprises a cutter body, a rough machining cutter head, a semi-finish machining cutter head and a combined special reamer; the circumference of the rough machining tool bit is uniformly welded at the front end of the cutter body, the circumference of the semi-finish machining tool bit is uniformly welded at the middle part of the cutter body, and the circumference of the special combined reamer is uniformly welded at the rear end of the cutter body; the outer diameter sizes of the rough machining tool bit, the semi-finishing tool bit and the combined special reamer are gradually increased according to machining allowance, and chip grooves are formed between the rough machining tool bit and the semi-finishing tool bit and between the semi-finishing tool bit and the combined special reamer; bolt holes are uniformly distributed in the circumference of the end face of the cutter body, a key groove is formed in the middle of the end face of one side of the cutter body, and a fabrication hole is formed in the end face of the other side of the cutter body. By using the cutter, three procedures of rough machining, semi-finish machining and reaming can be completed at one time, the machining efficiency can be improved, and the machining cost can be reduced.
Description
Technical Field
The utility model relates to a special tool, especially a trinity special tool that can once accomplish rough machining, semi-finishing and reaming.
Background
In machining, deep holes are often machined on a boring and milling machine, and the common machining method comprises the steps of firstly carrying out rough machining by using a rough boring cutter, then carrying out semi-finish machining, and finally carrying out reaming or inner hole grinding by using a reamer. The problems with this method of processing are: the cutter needs to be replaced and corrected for many times, the machining time is long, and the machining cost is high.
Disclosure of Invention
In order to solve the problem, the utility model provides a trinity special tool.
The utility model adopts the technical proposal that:
the three-in-one special cutter comprises a cutter body, a rough machining cutter head, a semi-finish machining cutter head and a combined special reamer; the circumference of the rough machining tool bit is uniformly welded at the front end of the cutter body, the circumference of the semi-finish machining tool bit is uniformly welded at the middle part of the cutter body, and the circumference of the special combined reamer is uniformly welded at the rear end of the cutter body; the outer diameter sizes of the rough machining tool bit, the semi-finishing tool bit and the combined special reamer are gradually increased according to machining allowance, and chip grooves are formed between the rough machining tool bit and the semi-finishing tool bit and between the semi-finishing tool bit and the combined special reamer; bolt holes are uniformly distributed in the circumference of the end face of the cutter body, a key groove is formed in the middle of the end face of one side of the cutter body, and a fabrication hole is formed in the end face of the other side of the cutter body.
The utility model has the advantages that: the three-in-one special cutter can realize one-time processing completion of three procedures without replacing and calibrating the cutter for many times, thereby greatly improving the processing efficiency and reducing the processing cost. If a certain machine frame is machined, the conventional cutter machining needs 37 hours, the special cutter machining is adopted, and the machining can be completed in only 5 hours and 35 minutes, so that the machining time is greatly shortened, the electric charge is saved, the equipment loss is reduced, and the labor intensity of workers is reduced. Simultaneously trinity cutter adopts many tool bits to arrange and the chip groove setting, can pour into the coolant liquid into in machine tooling for easy chip breaking, chip removal, lubrication and cooling have made processingquality obtain guaranteeing man-hour.
Drawings
The following is further illustrated in connection with the figures of the present invention:
fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a left side view of the structure of the present invention.
Fig. 3 is a right side view of the structure of the present invention.
In the figure, 1, a cutter body, 2, a rough machining cutter head, 3, a semi-finishing cutter head, 4, a combined special reamer, 5, a bolt hole, 6, a key groove, 7, a chip groove and 8, a fabrication hole are arranged.
Detailed Description
The three-in-one special cutter comprises a cutter body 1, a rough machining cutter head 2, a semi-finish machining cutter head 3 and a combined special reamer 4; the rough machining tool bits 2 are uniformly and circumferentially welded at the front end of the cutter body 1, the semi-finish machining tool bits 3 are uniformly and circumferentially welded at the middle part of the cutter body 1, and the combined special reamer 4 is uniformly and circumferentially welded at the rear end of the cutter body 1; the external diameter sizes of the rough machining tool bit 2, the semi-finishing tool bit 3 and the combined special reamer 4 are gradually increased according to the machining allowance, and chip grooves 7 are formed between the rough machining tool bit 2 and the semi-finishing tool bit 3 and between the semi-finishing tool bit 3 and the combined special reamer 4; bolt holes 5 are uniformly distributed on the circumference of the end face of the cutter body 1, a key groove 6 is formed in the middle of the end face of one side of the cutter body 1, and a fabrication hole 8 is formed in the end face of the other side.
When the three-in-one special tool is used, the tool body 1 is connected with the boring bar through the key groove 6 and is fastened with the boring bar through the bolt hole 5 by a bolt, so that the tool can rotate under the driving of the boring bar, and the whole process of finishing rough machining and semi-finish machining to reaming by one tool is realized.
