Description

Technical Field

[0001] This utility model relates to the field of MT ferrule processing technology, specifically to a cutting fixture for MT ferrule dust caps. Background Technology

[0002] The dust cap of the MT ferrule is mainly used to protect the end face of the ferrule from dust, scratches, or other contaminants. The cutting operation of this dust cap is mostly done manually. Due to the lack of dedicated tooling, there is no fixed positioning reference when cutting the dust cap. The cutting position is entirely determined by experience, resulting in irregular shapes and inconsistent cutting lengths of the dust cap after cutting. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a cutting fixture for MT ferrule dust caps, so as to solve the problem that the dust caps are cut in inconsistent shapes and lengths due to the lack of positioning reference in the existing technology.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: MT ferrule dust cap cutting fixture, including: The base is provided with several first positioning grooves for positioning the dust cap; A cover plate is placed on the base and can press the dust cap into the first positioning groove; The cover plate only partially covers the first positioning groove to divide the first positioning groove into a covered part and an exposed part. The exposed part is provided with a second positioning groove for positioning the cutting blade.

[0005] Furthermore, a first positioning surface is provided at the end of the covered portion that is away from the exposed portion.

[0006] Furthermore, the end of the cover plate facing the base is provided with several second positioning surfaces.

[0007] Furthermore, the cover plate has several notches at one end facing the base, the notches correspond to the first positioning groove, and their open ends face the exposed portion, and the second positioning surface is located at the closed end of the notches.

[0008] Furthermore, the cover plate is provided with a third positioning surface, which extends to the second positioning groove.

[0009] Furthermore, the cover plate is rotatably connected to the base.

[0010] Furthermore, the cover plate and the base are magnetically connected by a magnetic attractor.

[0011] Furthermore, the cover plate and / or the base are provided with clearance openings to avoid the magnetic suction component.

[0012] Furthermore, the base is provided with anti-slip pads and / or support legs.

[0013] Furthermore, the cover plate is provided with a handle.

[0014] Compared with existing technologies, this utility model has the following advantages: the dust cap can be initially positioned by the first positioning groove of the base, and then fixed in the first positioning groove by the cover plate to complete the secondary positioning, thereby forming a positioning reference before cutting, and ensuring that each dust cap can be accurately positioned in the same position before cutting; furthermore, the cover plate only partially covers the first positioning groove, so that the cutable part of the dust cap is always exposed, and the cutting blade is positioned by the second positioning groove, ensuring that the blade cuts at the same angle and position each time, and the positioning of the dust cap can ensure the cutting accuracy of the dust cap under the dual positioning effect; in addition, after the dust cap is cut, flipping the entire fixture can make the cut part fall off automatically, leaving only the usable part, realizing the rapid separation of the two to improve efficiency.

[0017] The present invention will be further described in detail below through specific embodiments: In the embodiments of this utility model, such as Figures 1-4As shown, the MT ferrule dust cap cutting fixture includes: a base 1 and a cover plate 2; the base 1 is provided with a plurality of first positioning grooves 3 for positioning the dust cap; the cover plate 2 covers the base 1 and can press the dust cap into the first positioning grooves 3; wherein, the cover plate 2 only partially covers the first positioning grooves 3 to divide the first positioning grooves 3 into a covered part 301 and an exposed part 302, and the exposed part 302 is provided with a second positioning groove 4 for positioning the cutting blade.

[0018] Specifically, in this embodiment of the invention, the base 1 is elongated, and its upper surface is provided with a first positioning groove 3. The size of the first positioning groove 3 is slightly larger than the size of the dust cap, so as to accommodate and initially position the dust cap (circumferential positioning of the dust cap). Of course, in order to improve cutting efficiency and cut multiple dust caps simultaneously (or in batches), multiple first positioning grooves 3 are provided at equal intervals on the base 1. The size and shape of the first positioning groove 3 can be adapted to the size and shape of the dust cap, and are not limited here.

[0019] In this embodiment of the invention, under the action of external force, the cover plate 2 can be placed on the base 1 or moved away from the base 1, thereby giving the cutting fixture a closed state and an open state. In the closed state, the cover plate 2 only partially covers the first positioning groove 3, dividing the first positioning groove 3 into a covered portion 301 covered by the cover plate 2 and an exposed portion 302 outside the cover plate 2. When the dust cap is placed in the first positioning groove 3, its usable portion is pressed by the cover plate 2 at the covered portion 301, completing secondary positioning (vertical positioning of the dust cap) to prevent it from jumping or shifting, while the portion to be cut is located at the exposed portion 302. After cutting, flipping the entire fixture allows the cut portion to fall freely, thus completing rapid separation. Conversely, in the open state, the cut dust cap can be removed or a new dust cap to be cut can be placed in.

[0020] In addition, to further improve the cutting accuracy, a second positioning groove 4 is provided in the exposed part 302. The second positioning groove 4 is used to accommodate and position the cutting blade so that the cutting blade always cuts the dust cap at the same angle and position.

[0021] This invention, through the cooperation of the first positioning groove 3 at the base 1 and the cover plate 2, can perform two positioning of the dust cap, ensuring that each dust cap is accurately positioned in the same position before cutting. During cutting, the cover plate 2 can be used to press the dust cap to prevent it from jumping or shifting. At the same time, only the cutting part is exposed outside the cover plate 2, which facilitates cutting and provides stable guidance and positioning for the cutting blade through the second positioning groove 4, ensuring that the blade cuts at the same angle and position each time. On the other hand, it also allows the cut-off part to fall freely when the fixture is flipped, thereby improving efficiency.

[0022] like Figure 3 , Figure 4 As shown, in one embodiment, a first positioning surface 5 is provided at the end of the covering portion 301 opposite to the exposed portion 302. Specifically, to improve the positioning accuracy of the dust cap, this embodiment provides a first positioning surface 5 located at the end face of the covering portion 301 opposite to the exposed portion 302, so that the first positioning surface 5 can serve as a positioning reference for the dust cap. Thus, when the dust cap is placed in the first positioning groove 3, with one end fitting against the first positioning surface 5, it can be ensured that each dust cap can be accurately positioned in the same position before cutting. Of course, using the inner sidewall of the covering portion 301 directly as the first positioning surface 5 can simplify the structure of the base 1.

[0023] like Figure 4 As shown, in one embodiment, the cover plate 2 is provided with a plurality of second positioning surfaces 6 at one end facing the base 1. Specifically, in order to facilitate the removal and placement of the dust cap, the upper part of the dust cap protrudes beyond the first positioning groove 3, so a second positioning surface 6 can be provided at one end of the cover plate 2 facing the base 1. The second positioning surface 6 is collinear with the first positioning surface 5; thus, when in the closed state, the second positioning surface 6 can position the protruding part of the dust cap, further improving its positioning accuracy.

[0024] Preferably, the cover plate 2 has a plurality of notches 7 at one end facing the base 1. The notches 7 correspond to the first positioning groove 3, and their open ends face the exposed portion 302. The second positioning surface 6 is located at the closed end of the notch 7. In other words, on the one hand, the notch 7 can accommodate the protruding part of the dust cap, that is, the protruding part can extend into the notch 7, which facilitates the positioning of the dust cap; on the other hand, the closed end of the notch 7 can also be used as the second positioning surface 6, making the structure simpler.

[0025] like Figure 2 , Figure 3 As shown, in one embodiment, the cover plate 2 is provided with a third positioning surface 8, which extends to the second positioning groove 4. Specifically, in order to further position the cutting blade, this embodiment defines the outer wall of the cover plate 2 as the third positioning surface 8, so that the third positioning surface 8 can be used as a guide surface for the blade to ensure its cutting angle. Furthermore, the third positioning surface 8 can extend or be close to the second positioning groove 4 so that the blade can be guided into the second positioning groove 4 for cutting.

[0026] In one embodiment, the cover plate 2 is rotatably connected to the base 1. Specifically, the base 1 is provided with a rotating shaft, and the cover plate 2 is disposed on the rotating shaft. Under the action of external force, the cover plate 2 can rotate relative to the base 1, thereby switching the fixture between an open state and a closed state.

[0027] Preferably, the cover plate 2 and the base 1 are magnetically connected by a magnetic attractor (not shown) to prevent the cover plate 2 from separating from the base 1 due to vibrations generated during cutting when the fixture is closed. Alternatively, the cover plate 2 and the base 1 can be magnetically connected using only a magnetic attractor; in this case, the cover plate 2 and the base 1 are separated when the fixture is open, and magnetically attracted to each other when closed. In other embodiments, the cover plate 2 and the base 1 can also be connected by a snap-fit ​​mechanism. The magnetic attractor includes several first magnets and several second magnets, which attract each other. Figure 3 , Figure 4 As shown, the cover plate 2 and / or the base 1 are provided with a clearance opening 9 for avoiding the magnetic suction component.

[0028] Of course, an anti-slip pad can be installed at the bottom of the base 1 to prevent slippage during cutting; and / or several legs can be installed at the bottom of the base 1 to raise it; or even a handle can be installed on the surface of the cover plate 2 for easy operation.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
