Description
Technical field
The utility model relates to Machining Technology field, is specifically related to a kind of scoring tool.
Background technology
According to pattern and requirement in kind, on blank or workpiece, the outline line marking position to be processed with scoring tool is called line as the operation of datum mark, line.Under normal circumstances, the workpiece blank of some more complicated and semi-finished product, when entering fine finishining, normal need rely on line as the foundation corrected, can check whether blank consistent with drawing requirement by line, can correct allowance make up blank exists some local defect, can also find and reject the blank that some cannot correct allowance early, in order to avoid waste the machining period of later process.But when ruling to Big Steel Castings forging piece, due to the surface irregularity of cast member, when ruling, workman needs the position ceaselessly adjusting scriber, with make scriber syringe needle can all the time with the surface contact of cast member, have a strong impact on line efficiency and line precision, also there is such problem to when inclined plane is rule.
Summary of the invention
The purpose of this utility model proposes a kind of scoring tool, and when using this scoring tool to rule, the syringe needle of scriber can hold out against the surface of workpiece to be crossed all the time, reduces line difficulty, improves line efficiency.
A kind of scoring tool described in the utility model, comprise sleeve and scriber, the inner chamber in blind hole shape is provided with in described sleeve, the opening of described inner chamber is positioned at one end of described sleeve, the other end of described sleeve is provided with the through hole with described coaxial, and the diameter of described through hole is less than the diameter of described inner chamber; Described scriber comprises in shaft-like needle body, one end of described needle body is the syringe needle of taper, the other end is provided with cylindrical slide block, described slide block is positioned at the inside of described sleeve and is slidably matched with described inner chamber, and described needle body and described through hole are slidably matched and described syringe needle is positioned at the outside of described sleeve; The opening part of described inner chamber is fixedly connected with end cap, the spring for holding out against described slide block is provided with between described end cap and described slide block, the sidewall of described inner chamber is provided with helicla flute, the sidewall at described inner chamber two ends is equipped with the cannelure be communicated with described helicla flute, described cannelure is less than described slide block along the width on described sleeve axis direction along the width on described sleeve axis direction, two cannelures are equipped with steam vent, and described steam vent is communicated with the outside of described inner chamber and described sleeve.
Further, the mode that described end cap is threaded connection coordinates with the opening of described inner chamber.
Further, the fit clearance of described slide block and described inner chamber is between 0.005cm-0.008cm.
In the utility model, the fit clearance of the inner chamber of slide block and sleeve is between 0.005 ~ 0.008cm, this ensure that the precision of line, makes scriber accurate positioning and stablizes.The inner chamber of sleeve is provided with helicla flute, the effect of oil extraction, exhaust, the tiny iron filings of row is played in skid process, be provided with at the two ends of inner chamber the cannelure be communicated with helicla flute simultaneously, cannelure is also provided with steam vent, convenient collection and discharge oil, gas and little iron filings, play the effect preventing oil, gas and little iron filings from refluxing simultaneously, make the energy easy slide when fit clearance is minimum of slide block and sleeve.Arrange spring, and spring holds out against slide block all the time, scriber can be adjusted automatically along with the shape on the surface of workpiece to be crossed, the syringe needle reaching scriber holds out against the surface of line workpiece all the time, reduces line difficulty, improves line efficiency.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
A kind of scoring tool as shown in Figure 1, comprises sleeve 1 and scriber 2.As shown in Figure 3, be provided with the inner chamber in blind hole shape in described sleeve 1, the opening of described inner chamber is positioned at one end of described sleeve 1, and the other end of described sleeve 1 is provided with the through hole 9 with described coaxial, and the diameter of described through hole 9 is less than the diameter of described inner chamber.As shown in Figure 2, described scriber 2 comprises in shaft-like needle body, one end of described needle body is the syringe needle of taper, the other end is provided with cylindrical slide block, described slide block is positioned at the inside of described sleeve 1 and is slidably matched with described inner chamber, the fit clearance of described slide block and described inner chamber is between 0.005cm-0.008cm, and described needle body and described through hole 9 are slidably matched and described syringe needle is positioned at the outside of described sleeve 1, the opening part of described inner chamber is fixedly connected with end cap 3, the mode that described end cap 3 is threaded connection coordinates with the opening of described inner chamber, the spring 5 for holding out against described slide block is provided with between described end cap 3 and described slide block, the sidewall of described inner chamber is provided with helicla flute 6, the sidewall at described inner chamber two ends is equipped with the cannelure 7 be communicated with described helicla flute 6, described cannelure 7 is less than described slide block along the width on described sleeve 1 axis direction along the width on described sleeve 1 axis direction, two cannelures 7 are equipped with steam vent 8, described steam vent 8 is communicated with the outside of described inner chamber and described sleeve 1.The outer wall of sleeve 1 is provided with syndeton 4, syndeton 4 is for being arranged on track or unit structure by sleeve 1, to rule to workpiece to be crossed, the syndeton 4 in the present embodiment, for being arranged on the flange on the outer wall of sleeve 1, flange can arrange bolt hole.
Above-mentioned scoring tool in use, first through measuring, in the outer setting of workpiece to be crossed as the slide rail of scribe fiducials or pedestal, then utilize syndeton 4 to be arranged on slide rail or pedestal by this scoring tool, and make the syringe needle of scriber 2 hold out against workpiece to be crossed.Then according to the needs of line; this scoring tool mobile; syringe needle just marks the mark line of needs on the surface of workpiece to be crossed; in this process; under the effect of spring 5, scriber 2 can shrink and stretch out, and guarantees that syringe needle holds out against the surface of workpiece to be crossed all the time; spring 5 can also protect syringe needle simultaneously, avoids syringe needle and is impacted.This scoring tool arranges helicla flute 6 on the inner chamber of sleeve 1, and ensure that the inner chamber of slide block and sleeve 1 is under less fit clearance, slide block can reciprocatingly slide freely, makes this scoring tool have higher line precision.
