Special tool for alignment of machining position

Technical Field

The utility model relates to a machining tool technical field especially relates to a special tool is aligned to machining position.

Background

The tool setting mode of turning mainly adopts two methods: tool setting instrumental style and trial cutting tool setting mode. Although the tool setting gauge is simple and convenient to use and can directly input data into a numerical control system, the tool setting gauge needs each machine tool to be separately provided with a tool setting gauge part, the price of the tool setting gauge is not high, each tool setting gauge can only be used corresponding to one machine tool, and the equipment cost is high. At present, the machine tool is generally only configured and used on a high-end machine tool, and is not beneficial to popularization and application.

When the surface of the round shaft is drilled, milled, planed and plunged vertically or at a certain angle, the clamping bench clamp with an adjustable angle needs to be replaced, and the technical level of an operator is very studied.

The angle plate or the universal angle ruler which is needed to be used for sharpening the cutter has single function.

In the machining industry at present, two common workpiece center alignment methods include a three-jaw chuck method and a meter-drawing adjustment method, wherein the three-jaw chuck method directly clamps a workpiece by using a self-centering three-jaw chuck, the center of the workpiece is overlapped with the axis of a rotating shaft, the alignment accuracy of the method mainly depends on the repeated positioning accuracy of the three jaws, the accuracy of the method is reduced along with the increase of clamping times, the relative position of the method and the rotating shaft is also deviated, and the center clamping positioning accuracy of the workpiece is difficult to ensure.

In conclusion, the existing mechanical processing industry has complete tools and measuring tools, but the purposes are single, the position alignment is time-consuming, and the technical level of a technician is tested.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in further detail with reference to the following embodiments and accompanying drawings.

As shown in fig. 1 and 2, the special tool structure for alignment of machining positions comprises a clamping handle rod 1, an angle plate 2 and a fixing bolt 3; the clamping handle rod 1 is connected with the angle plate 2 through the fixing bolt 3.

The upper end of the clamping handle rod 1 is provided with a round shaft which is clamped on a milling chuck and a drilling chuck; one third of the upper part of the clamping handle rod 1 is provided with a plane protrusion part, and the plane protrusion part is clamped on a lathe tool rest or a planer tool rest or an slotting machine tool rest for position alignment. And the middle part of the clamping handle rod 1 is provided with an axis.

The angle plate (2) is provided with scales, the scales of the angle plate are accurate to 0.5 ℃, and the verticality and the parallelism are accurate to 0 ℃. And one side of the angle plate is provided with fixed angles of 32 degrees, 45 degrees, 60 degrees and 120 degrees. And the lower part of the angle plate is provided with a bayonet which is used for aligning the axle center point and the center position of the round bar stock and the square stock.

The clamping handle rod 1 and the angle plate 2 are made of tool steel materials; the size of the clamping handle rod is 16X16X190 (unit mm); the connection of the clamping handle rod and the angle plate adopts a fixed bolt, and the whole size is 80X245X16 (unit mm). When the device is used, the handle rod is fixedly clamped, and the angle plate is rotated to align the angle position of a workpiece and the main shaft through the fixed clamping handle rod, so that the aim of alignment is fulfilled. Thereby being convenient for processing and saving time.

The embodiment adopts the design of an axis principle, the precision of the alignment device is not influenced by external factors, and the alignment precision can be effectively ensured; the tool setting device does not need a special clamping device, can be directly used in a tool clamping sleeve of equipment such as a lathe, a milling machine, a drilling machine, a planer, a slotting machine, a grinding machine and the like for tool setting operation and position alignment, and has strong practicability.
