Description

Technical Field

[0001] The utility model relates to the technical field of processing and scribing, in particular to an elastic scribing tool. Background Art

[0002] Machining marking is to use specific tools to draw predetermined lines during the machining process to mark important information such as the position, size and shape of the workpiece. In the actual working process, since the surface of the blank is not completely flat, especially the surface profile tolerance of the casting blank is large. After the machine tool is clamped, the product is in the benchmark alignment process. When the ordinary full-rigid measurement or cutting tool head encounters an abnormal raised part on the surface of the blank, the tool head may interfere with the workpiece excessively and collide with the tool, resulting in damage to the tool head. In severe cases, the impact force is transmitted to the machine tool motion system, damaging the machine tool.

[0003] Existing patents have also taken this aspect into consideration. For example, the application number 202321968412.5 discloses a flexible engraving tool device. A flexible contraction mechanism is used inside the tool bar, so that the tool can adjust the axial position of the tool according to the surface state of the part when cutting the uneven surface of the blank, thereby achieving flexible cutting, ensuring that the tool is not damaged at the high point of the workpiece, and ensuring that the cutting line is clean and visible, achieving good engraving and line engraving effects. For example, the application number 202120853657.8 discloses a tool for engraving positioning lines on plastic panels. The position of the tool head can be changed by setting a spring. When the tool engraves lines on a plastic plate, the pressure causes the spring to contract, and the length of the tool head changes elastically, which can effectively prevent the depth of the engraving from being too deep and affecting the use of plastic panels.

[0004] However, the existing patents do not take into account that the tool bar needs to have a retracting function, so it is usually placed in a sleeve or a shell. The sleeve or shell itself has a certain volume and width, which will affect the operator's observation of the cutter head's engraving work and the adjustment of the cutter head's position. In addition, there is almost no consideration of visualizing the dynamic retraction of the tool bar, so the operator cannot intuitively understand the degree of abnormal protrusion on the blank surface. Utility Model Content

[0005] The utility model aims to provide an elastic scoring tool, which is convenient for observing the unevenness of the blank surface when scoring by arranging an observation window on the side wall of the transparent shell at a position corresponding to the level of the supporting spring, so that the operator can intuitively understand the abnormal convexity of the blank surface.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: an elastic engraving tool, comprising a vertically arranged transparent shell, a knife rod is vertically arranged in the transparent shell, a knife is arranged at the bottom of the knife rod, and the knife extends out of the transparent shell; a support spring is arranged at the top of the knife rod, a nut plug is arranged at the top of the support spring, and a thread matching the nut plug is arranged on the inner wall of the top of the transparent shell, which is used for rotating the nut plug to adjust the strength of the compression support spring; an observation window is arranged on the side wall of the transparent shell at a position corresponding to the horizontal position of the support spring, and a scale is arranged vertically at the observation window for understanding the dynamic activity degree of the knife rod.

[0007] Preferably, the tool is tapered as a whole, with a cylindrical bottom and a tapered bottom.

[0008] Preferably, the shape of the bottom of the transparent shell is adapted to the cutter, and the cross-sectional area of ​​the transparent shell gradually decreases from top to bottom.

[0009] Preferably, the starting position of the scale is flush with the rear end of the knife rod.

[0010] Preferably, the knife and the knife rod are both made of high-chromium stainless steel.

[0011] The beneficial effects of the utility model are:

[0012] This solution provides a transparent shell around the tool bar and the tool, which will not affect the operator's observation of the tool head's marking work and adjustment of the tool head's position. In addition, an observation window is provided on the side wall of the transparent shell at a position corresponding to the level of the support spring, so as to facilitate observation of the unevenness of the blank surface during marking, and the operator can intuitively understand the degree of abnormal protrusion on the blank surface. The starting position of the scale is flush with the rear end of the tool bar, which further provides a digitized and parameterized understanding of the degree of abnormal protrusion on the blank surface. The top inner wall of the transparent shell is provided with a thread matching the nut plug, which is used for the nut plug to rotate and adjust the strength of the compression support spring, thereby adjusting the marking force of the tool.
