Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing, and specifically relates to a steerable fitter's scribing fixture. Background Technology

[0002] Currently, there are a large number of welded and cast parts in machined parts. Before machining, they need to be scribing by fitter. However, many parts are not regular rectangles and have bevels. Conventional scribing methods have errors caused by secondary clamping and difficulties in aligning the bevels.

[0003] Chinese patent CN107598887B discloses a multi-functional scribing table. Although this patent can perform multi-directional scribing of inclined surfaces, straight dimensions, and angle dimensions on a workpiece in one go using a scribing needle, effectively solving the problems of low scribing efficiency and high labor intensity of existing fitter scribing tools, the installation of the workpiece to be scribed is relatively complicated. When different lines need to be drawn, the corresponding components need to be adjusted. For example, when it is necessary to draw a vertical parallel line, the workpiece needs to be mounted on the indexing turntable, clamped with screws, and the indexing turntable needs to be zeroed and locked before the vertical parallel line can be drawn. Moreover, there is a need to replace the screws, which increases the cost of use. In addition, the scribing table of this patent has a relatively complex structure. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a steerable fitter's marking fixture.

[0005] This utility model is achieved through the following technical solution.

[0006] A steerable fitter's marking fixture includes a base plate, a flat plate, two support plates, a rotating shaft, a semi-circular guide rail, and a limiting shaft. The two support plates are vertically inserted into and screwed onto the top of the base plate. The flat plate is rotatably mounted between the upper parts of the two support plates via the rotating shaft. The limiting shaft is fixedly mounted between the lower parts of the two support plates. The semi-circular guide rail is provided with a limiting slot, and the limiting shaft is inserted into the limiting slot. The inner sides of both ends of the semi-circular guide rail are screwed to the front and rear ends of the flat plate.

[0007] The upper surface of the plate has multiple evenly distributed T-shaped openings, which are used to fix the parts to be processed.

[0008] A bearing is nested between the support plate and the rotating shaft, and the support plate and the bearing are fixedly connected.

[0009] The limiting slot is located on the side of the semi-circular guide rail and is configured to pass through.

[0010] The limiting slot is semi-circular in shape, and the length direction of the limiting slot is in the same direction as the length direction of the semi-circular guide rail.

[0011] The semi-circular guide rail is engraved with angle markings.

[0012] A pad is provided between the inner side of the upper part of the support plate and the outer side of the flat plate.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The T-shaped slot serves to fix the parts in place when the plate is rotated;

[0015] 2. By using bearings, the friction between the support plate and the rotating shaft is reduced, which makes the rotation of the plate smoother, reduces energy consumption, and extends the service life of the steerable fitter's scribing tool.

[0016] 3. By rotating the plate through the angle scale, the angle of the part can be changed, thus achieving the purpose of scribing on the beveled surface of irregular parts;

[0017] In summary, this utility model realizes the function of turning the part in one clamping during scribing, solves the problem of scribing on the inclined surface of the part, and the scribing fixture has a simple structure and low cost of use. Attached Figure Description

[0025] The technical solution of this utility model is further described below with reference to the accompanying drawings and embodiments, but the scope of protection is not limited to the description.

[0026] Example: Reference Figures 1-4 .

[0027] like Figure 1 The diagram shown is a structural schematic of a steerable fitter's marking fixture according to this utility model. Figure 2 The diagram shows a steerable fitter's scribing fixture according to an embodiment of the present invention. The fixture includes a base plate 1, a flat plate 2, two support plates 3, a rotating shaft 5, a semi-circular guide rail 7, and a limiting shaft 8. Two support plates 3 are vertically inserted and screwed onto the top of the base plate 1, increasing the stability of the support plates 3 and the base plate 1. The flat plate 2 is rotatably mounted between the upper parts of the two support plates 3 via the rotating shaft 5, allowing the flat plate 2 to rotate. The limiting shaft 8 is fixedly installed between the lower parts of the two support plates 3, fixing the angle of the semi-circular guide rail 7 and preventing inaccurate scribing when scribing parts 11. The semi-circular guide rail 7 has a limiting slot 10, into which the limiting shaft 8 is inserted. The inner sides of both ends of the semi-circular guide rail 7 are screwed to the front and rear ends of the flat plate 2. The cooperation between the limiting shaft 8 and the limiting slot 10 makes the semi-circular guide rail 7 more stable when rotating at a certain angle.

[0028] The upper surface of the plate 2 has multiple evenly distributed T-shaped slots 9. The T-shaped slots 9 are used to fix the parts 11 to be processed. The parts 11 have different inclined surfaces. After leveling the parts 11, the parts 11 are fixed on the plate 2. The angle of the parts 11 can be changed by rotating the plate 2. During the rotation of the plate 2, the T-shaped slots 9 clamp and fix the parts 11 to avoid instability of the scribing.

[0029] A bearing 4 is nested between the support plate 3 and the rotating shaft 5. The support plate 3 and the bearing 4 are fixedly connected. The bearing reduces the friction between the support plate and the rotating shaft, making the rotation of the plate smoother, reducing energy consumption, and extending the service life of the steerable fitter's scribing tool.

[0030] The limiting slot is located on the side of the semi-circular guide rail 7, and the limiting slot is through-hole.

[0031] The limiting slot is semi-circular in shape, and the length direction of the limiting slot is in the same direction as the length direction of the semi-circular guide rail 7, so that the semi-circular guide rail 7 can rotate within the limiting angle range of the limiting slot.

[0032] For reference Figure 3 The front view of the present utility model embodiment shown; and as shown in the figure Figure 4 The present invention shown Figure 3A magnified structural diagram of part A; the semi-circular guide rail 7 is engraved with angle scale 13. By rotating the plate through angle scale 13, the angle of the part can be changed, thus achieving the purpose of scribing the inclined surface of the irregular part.

[0033] A pad 6 is provided between the upper inner side of the support plate 3 and the outer side of the plate 2. The use of the pad 6 reduces the frictional loss between the support plate 3 and the plate 2.

[0034] refer to Figure 5 The present invention shown Figure 1 Enlarged structural diagram of part B; Two limiting posts 14 are fixedly installed above the base plate 1 and between the two support plates 3. The two limiting posts 14 are located on the left and right sides of the semi-circular guide rail 7 respectively, to prevent the semi-circular guide rail 7 from swaying left and right when the angle is fixed during rotation, causing angle deviation and making the slant line of the part inaccurate.

[0035] refer to Figure 6 The working process of this utility model is shown as follows: After the tooling is processed, since the guide rail 7 is engraved with angle scales, the part 11 to be processed is fixed on the plate 2. The angle of the part 11 is changed by rotating the plate 2. Since the dimensions between the angle plate 2 and the base plate 1 are fixed, after rotating the angle, the scribing ruler 12 can be used to scribing the part 11 on the base plate.

[0036] 1. Level the part using the non-machined surface of the inner cavity as a reference, and mark the thickness dimension line 12.5;

[0037] 2. Draw the height dimension line at 185.5 and the total height dimension line at 450.9;

[0038] 3. Draw the slope height dimension line 60.1;

[0039] 4. Turn 90°, using the top inner cavity as a reference, take the middle value of the thickness, and draw a dimension line downwards of 7.5;

[0040] 5. Draw the overall length dimension line 1137.6;

[0041] 6. Dimension line of the inclined plane: 975.7;

[0042] 7. Turn 112.5° = 90 + 22.5, find the intersection of 1 and 5, and draw the dimension line for the 22.5° inclined plane;

[0043] 8. Draw the thickness dimension line 423 for the bevel.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope of the technology disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
