Description
Technical Field
The invention relates to the field of lathe machining tool fixtures and equipment, in particular to a novel adjustable tool rest.
Background
In the machining industry, a lathe is a machining tool which is most widely applied, the lathe is provided with a tool rest, various machining tools, namely turning tools, are arranged on the tool rest, the inner and outer rotating surfaces, the end surfaces and various inner and outer threads of a workpiece can be machined, and machining such as drilling, reaming, knurling and the like can be carried out.
One of the key parts of lathe processingquality is the lathe tool, and the convenient and fast change and the installation and debugging of lathe tool, lathe tool knife tip center height that uses at present, realize through adjustment gasket thickness, through the quantity that increases or reduces the gasket promptly, make the knife tip of lathe tool aim at the center by the processing work piece, it is longer to spend time at the tool setting in-process, because the thickness of gasket differs, the adjustment lathe tool also has certain difficulty at the central point of work piece, thereby influence the precision and the speed of processing work piece, the production efficiency is reduced, waste product also appears easily, the personal accident appears even.
The existing tool rest is only provided with a mounting seat used for mounting a turning tool, namely, only one turning tool can be mounted on the tool rest of the lathe, after a certain number of workpieces are processed, the cutting edge of the turning tool can be worn and stewed, or the next procedure is needed to be carried out for processing, the turning tool needs to be replaced, the turning tool is frequently replaced and calibrated, and time and labor are wasted.
Disclosure of Invention
In order to solve the problems in the prior art, the invention provides a novel adjustable tool rest.
The technical scheme adopted by the invention is as follows:
a novel adjustable knife rest comprises a knife rest main body with an inner circle and an outer square, wherein the outer vertical surface of the knife rest main body is connected with a knife rest sliding block capable of sliding up and down; and the upper end of the tool rest sliding block is provided with a pressing bolt.
When the lifting screw rod rotates, the screw rod nut, the tool rest sliding block and the turning tool are driven to move up and down together.
Further, the number of the outer vertical surfaces of the tool rest main body is three to eight, preferably four, and dovetail guide rails and dovetail grooves are adopted for sliding connection between the outer vertical surfaces of the tool rest main body and the tool rest sliding blocks; the tool rest sliding block is of a concave structure, the opening of the concave structure is outward, and the tool rest sliding block is used for accommodating a turning tool and facilitating the assembly and disassembly of the turning tool.
The improved structure is characterized in that the upper end of the lifting screw rod is connected with a micrometer screw rod, and an upper screw rod of the micrometer screw rod is connected with an extending part of the tool rest main body.
The micrometer screw structure comprises a lower screw, a double-headed nut and an upper screw which are connected with each other;
1) a straight ruler line is carved on the outer cylindrical surface of the lower screw rod, and the upper side threads of the lower screw rod enter the lower screw hole of the double-headed nut;
2) the lower side threads of the upper screw rod enter the upper screw hole of the double-headed nut;
3) be carved with 50 dividing lines on the double-end nut lower extreme conical surface, screw pitch is 0.5mm bigger than last screw pitch under the double-end nut, so, double-end nut rotates the round, and the length variation of micrometer screw is 0.5mm, and double-end nut is every 1 check of commentaries on classics promptly, and the length variation of micrometer screw is 0.01 mm.
Therefore, after the upper end of the lifting screw rod is connected with the micrometer screw rod, the adjusting precision of the lifting screw rod can reach 0.01 mm.
The invention has the beneficial effects that:
1) the combination of the lifting screw rod, the screw rod nut and the tool rest sliding block is used, when the lifting screw rod rotates, the screw rod nut, the tool rest sliding block and the turning tool are driven to move up and down together, the center height of the tool tip of the turning tool is accurately adjusted, the operation is convenient, rapid and reliable, and the processing quality of a workpiece is guaranteed;
2) the number of the outer vertical surfaces of the tool rest main body is three to eight, and the tool rest main body can process different types of workpieces at one time by matching with a corresponding number of tool rest sliding blocks and turning tools without frequently replacing and setting the turning tools, so that the tool changing time is saved, and the production efficiency is greatly improved;
3) a micrometer screw is added in the matching way, so that the turning tool can be adjusted more accurately, the adjustment accuracy can reach 0.01mm, and a high-precision sharp workpiece can be machined;
4) the invention has simple and stable structure, easy field operation and low manufacturing cost, and has great popularization and application values.
