Abstract

The utility model discloses a scriber which comprises a base (3), a slide block (4) and a scribing awl (6), wherein the base (3) is provided with a sliding chute, the slide block (4) is arranged in the sliding chute, the scribing awl (6) is fixed at one end of the slide block (4), and the base (3) is provided with a locking device and a positioning device; the distance between a tip of the scribing awl (6) and a reference measuring surface of a convex block (32) is measured or adjusted firstly, so that the distance is equal to an allowance size; then, the slide block (4) is locked by the locking device, in the process of scribing, the positioning device positions and is tightly adhered to a reference surface of an assembling tool, the scriber moves along the reference surface, and the tip of the scribing awl (6) quickly scribes an allowance line (11) on a metal plate part, in such a way, when the scriber scribes a line on the metal plate part with a curved surface, the tip of the scribing awl is always adhered to the surface of the curved surface, so that the line is not scribed obliquely, therefore, the scriber disclosed by the utility model is accurate in scribing, convenient to operate, and high in scribing efficiency.

Description

A kind of scriber

Technical field

The utility model relates to a kind of scriber, relates in particular to the scriber that marks flat plate margin in a kind of sheet metal part assembling.

Background technology

In some sheet metal part assembling, the sheet metal part that at first needs to leave surplus is positioned in the assembly tooling, then the riveted joint of parts such as skeleton, rib is assembled together; Completion assembling back is that benchmark marks the surplus line with the frame inner edge of assembly tooling, removes the surplus limit by the surplus line at last, and the size of the frame of described assembly tooling is to add that according to sheet metal part appearance and size a surplus limit size design forms; What mark now that the surplus line adopts is to use earlier Steel Ruler to measure the surplus size with assembler's inner edge that frames up as benchmark; Rule against guiding ruler with the hard scriber according to this size then, the shortcoming of this kind method is when sheet metal part has curved surface, the guiding ruler curved surface of can't fitting fully; Draw askew during the scriber line easily; And the process of line is loaded down with trivial details, inconvenient operation, and line efficient is not high.

Summary of the invention

The technical problem that the utility model will solve is to provide a kind of accurate, easy to operate, high scriber of line efficient of ruling.

For solving the problems of the technologies described above, a kind of scriber of the utility model comprises pedestal, slide block and scriber; Have chute on the described pedestal, described slide block places chute, and described scriber is fixed on an end of slide block; It is characterized in that described pedestal is provided with locking device and positioner.

Described positioner is the projection that base bottom surface one is given prominence to, and projection has a side as the reference measurement face.

Described locking device is included in the groove of making on the slide block and passes groove and is screwed onto the lock-screw on the pedestal.

Described scriber is the barred body that an end has needle point, is shaped on screw thread on the barred body, and scriber is connected with the slide block threaded one end.

Be carved with dimension line on the chute both sides of described pedestal, be carved with the size index line on the described slide block, the scale value shown in the dimension line that index line points to is consistent to the distance of projection reference measurement face with the scriber needle point.

The barred body of described scriber is provided with stop nut.

The utility model has following good effect than prior art, and a kind of scriber of the utility model is before the line; Adjust the relative position of slide block and pedestal earlier, fixedly scriber measures the scriber needle point and makes it to equate with the surplus size with the distance of projection reference measurement face; Lock slide block then, the projection reference measurement face during line on the pedestal is close to assembler's inner edge that frames up, and scriber moves along assembler's inner edge that frames up; The needle point of scriber marks the surplus line fast on sheet metal part, when being carved with dimension line and size index line on pedestal and the slide block respectively, the distance of scriber needle point and projection reference measurement face can directly be illustrated by scale value; The scriber needle point was fitted with curved surface all the time when this sample scriber was rule on the sheet metal part of curved surface is arranged; Can not draw askew, therefore line accurately, easy to operate, line efficient is high.

Description of drawings

Below in conjunction with accompanying drawing and specific embodiment the utility model is done further explain.

Fig. 1 is the structural representation of a kind of scriber of the utility model.

Fig. 2 is the sketch map of user mode of a kind of scriber of the utility model.

Among the figure: 1. assembly tooling, the 11. assemblers inner edge that frames up, 2. sheet metal part, 22. surplus lines, 3. pedestal, 31. dimension lines, 32. projections, 4. slide block, 41. grooves, 5. lock-screw, 6. scriber, 7. stop nut.

The specific embodiment

Fig. 1 and Fig. 2 show a kind of scriber of the utility model; Comprise pedestal 3, slide block 4 and scriber 6; Have chute on the described pedestal 3, described slide block 4 places chute, and described scriber 6 is fixed on an end of slide block 4; It is characterized in that described pedestal 3 is provided with locking device and positioner.

Described positioner is the projection 32 that give prominence to pedestal 3 bottom surfaces one, and projection 32 has a side as the reference measurement face.

Described locking device is included in the groove of making on the slide block 4 41 and passes groove 41 and is screwed onto the lock-screw 5 on the pedestal 3.

Described scriber 6 is barred bodies that an end has needle point, is shaped on screw thread on the barred body, and scriber 6 is connected with slide block 4 threaded one ends.

Be carved with dimension line 31 on the chute both sides of described pedestal 3, be carved with the size index line on the described slide block 4, the scale value shown in the dimension line that index line points to is consistent to the distance of projection 32 reference measurement faces with scriber 6 needle points.

The barred body of described scriber 6 is provided with stop nut 7.

In sheet metal part 2 assemblings, the sheet metal part 2 that at first needs to leave surplus is positioned in the assembly tooling 1, then the riveted joint of parts such as skeleton, rib is assembled together; After accomplishing assembling, carry out line work, before the line; With the screwed hole of scriber 6 screw-in slide blocks 4 one ends, it is fixing with scriber 6 to tighten stop nut 7, unclamps lock-screw 5 again; The relative position of adjustment slide block 4 and pedestal 3; Measure scriber 6 needle points and make it to equate with the surplus size with the distance of projection 32 reference measurement faces, when being carved with dimension line 31 with the size index line respectively on pedestal 3 and the slide block 4, the distance of scriber 6 needle points and projection 32 reference measurement faces can directly be illustrated by scale value; Tighten lock-screw 5 then with locking slide block 4; The reference measurement face of the projection 32 during line on the pedestal 3 is close to assembler's inner edge 11 that frames up, and scriber moves along assembler's inner edge 11 that frames up, and the needle point of scriber marks surplus line 22 fast on sheet material.
