Abstract
The utility model discloses a thread position special-purpose measuring instrument used for the numerically controlled lathe thread maintenance. The thread position special-purpose measuring instrument includes an instrument gauge which is used to display the measurement data and a tooth-shaped block which is provided with thread teeth. The thread teeth of the tooth-shaped block are consistent with a standard thread of a to-be-maintained part thread. The tooth-shaped block is connected with the instrument gauge via a connecting rod. The instrument gauge is a dial indicator or a dial gauge. The connecting rod is in an L shape. The instrument gauge is arranged on an arm rod of the L-shaped connecting rod. The thread position special-purpose measuring instrument is used to measure the displacement deviation value along the axial direction between the to-be-maintained part thread and a standard qualified thread in the numerically controlled lathe thread maintenance so as to provide accurate key data for the tool setting process. The thread position special-purpose measuring instrument has the characteristics of simple structure, easy operation, high precision, high reliability, strong practicality, less time and labor, and low cost.
Description
Technical field
The utility model relates to a kind of survey instrument, specifically is a kind of screw position special measurement appearance that is used for numerically controlled lathe maintenance screw thread.
Background technology
For a long time, the screw thread repair all is to adopt engine lathe to accomplish.Carry out tool setting, cutting feeding and conversion knife bar owing to rely on fully to operate manually, make engine lathe repair screw thread and have shortcomings such as labour intensity is big, operative skill requires height, production efficiency is low.Add factors such as the engine lathe intrinsic accuracy is low, the accuracy of thread after the maintenance is also on the low side.Numerically controlled lathe has advantages such as intelligent degree height, precision machining, lathe good stability, production efficiency are high and easy to operate, if can realize numerically controlled lathe maintenance screw thread technology, will obviously reduce labour intensity, enhances productivity and keeps in repair accuracy of thread.
But,, have many difficulties and adopt numerically controlled lathe to repair screw thread, like problem of cutting tool because the screw thread repair is carried out on original thread groove basis.In engine lathe, tool setting is to adopt artificial hand mode that point of a knife is aimed in the thread groove, observes cutter position with naked eyes.The numerically controlled lathe automaticity is high, if adopt the manual mode tool setting, then can not bring into play its advantage.Spindle of numerical control lathe rotates and tool feeding is that the pulse signal that relies on the lathe inner encoder to send instructs.If can will wait to repair screw thread and the displacement difference of standard thread when tool setting measures; To be worth again through conversion and be input to the time that pulse signal takes place that changes in the digital control system; Just can realize automatic tool preset, and then for realizing that numerically controlled lathe maintenance screw thread provides critical data.For this reason, be badly in need of a kind of screw position special measurement appearance that is used for numerically controlled lathe maintenance screw thread of independent research at present.
Summary of the invention
The purpose of the utility model is: to the deficiency of above-mentioned prior art; A kind of screw position special measurement appearance that is used for numerically controlled lathe maintenance screw thread is provided; This measuring instrument is simple, practical; The tool setting operation of keeping in repair the part screw thread for numerically controlled lathe provides authentic data, guarantees its quick, accurately tool setting.
The technical scheme that the utility model adopts is: a kind of screw position special measurement appearance that is used for numerically controlled lathe maintenance screw thread; Comprise the instrumentation table that is used to show measurement data; Also comprise profile of tooth piece with thread; Thread on this profile of tooth piece is consistent with the standard thread of waiting to repair the part screw thread, and said profile of tooth piece connects instrumentation table through connecting link.
Said instrumentation table is dial gauge or clock gauge.
The L-shaped shape of said connecting link, instrumentation table are installed on the armed lever of " L " shape connecting link.
The beneficial effect of the utility model is: the measuring instrument of said structure can be used to measure the screw position axial displacement deviate of waiting to repair screw thread, and operating for the tool setting of numerically controlled lathe maintenance screw thread provides critical data accurately, realizes quick, accurately tool setting.It has simple in structure, easy to operate, degree of accuracy is high, reliability is high, characteristics such as practical, time saving and energy saving and cheap.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model.
Fig. 2 is the side view of Fig. 1.
Code name implication among the figure: 1-profile of tooth piece; 2-connecting link; 3-armed lever; 4-dial gauge.
Embodiment
Referring to Fig. 1 and Fig. 2: the utility model comprises the instrumentation table that is used to show measurement data, and this instrumentation table adopts dial gauge 4, if measurement data is required that higher degree of accuracy is arranged, then can adopt clock gauge.The utility model has also comprised a profile of tooth piece 1, has thread in a side of profile of tooth piece 1, and this thread is consistent with the standard thread of waiting to repair the part screw thread.Above-mentioned profile of tooth piece 1 connects dial gauge 4 through the connecting link 2 of a L-shaped shape, and profile of tooth piece 1 is installed in the upper end of " L " shape connecting link 2, and dial gauge 4 is installed on the armed lever 3 of " L " shape connecting link 2.
Profile of tooth piece 1 is various with the connected mode of dial gauge 4 and connecting link 2, promptly can adopt to be threaded, and also can adopt welding, can also adopt riveted joint, and concrete connected mode requires to choose at random according to practical operation.But, change operation for ease, profile of tooth piece 1 adopts usually with the connected mode of connecting link 2 with dial gauge 4 and is threaded, and when waiting to repair the part screw thread not simultaneously, gets final product with connecting link 2 through changing corresponding profile of tooth piece 1.
The course of work of the utility model is: at first that the whorl work piece clamping is good, screw position special measurement appearance profile of tooth piece is positioned over a certain position on the screw thread, and make the instrumentation table pointer contact readout equipment table dial plate reading and record with a certain vertical plane in main shaft the place ahead.This numerical value is the critical data in the screw thread maintenance tool setting process.
Claims (3)
1. one kind is used for the screw position special measurement appearance that numerically controlled lathe keeps in repair screw thread; Comprise the instrumentation table that is used to show measurement data; It is characterized in that: also comprise profile of tooth piece (1) with thread; Thread on this profile of tooth piece (1) is consistent with the standard thread of waiting to repair the part screw thread, and said profile of tooth piece (1) connects instrumentation table through connecting link (2).
