1. a kind of invention slotless round bar internal channel digital display calliper belongs to precision machinery manufacture field, than traditional round bar internal channel digital display Slide calliper rule, feeling is better, and round bar shaking volume is smaller, and product manufacture is simpler, and more reliable performance, appearance is more beautiful, technology It is characterized in:

Main scale (2) back side slotless, garden bar (5) one end process a plane, and Cheng Banyuan is shown in Fig. 3, are embedded in ruler frame (7) semi-round groove, With sub- arc welding, semi-round groove has anti-rotation function, does not loosen convenient for garden bar (5) when assembly and disassembly groove measuring head, the garden in measurement Bar (5) and main scale (2) keep 0.1 to 0.2 gap, and garden bar (5) directly puts in survey in bore and move, and digital display component (3) increases to the right Amount is general with the digital display component of all kinds of digital display callipers.

2. according to claim 1, main scale (2) back side not groove milling.

3. Ju claim 1 garden bar (5) one end processes a plane, it is embedded in ruler frame (7) semi-round groove, sub- arc welding.

4. one symmetry bench rank of main scale right (2) end processing according to claim 1 is pressed into seat (4) interference fit is surveyed.

0.1mm is narrowed down to by 0.3mm 5. surveying seat (4) and round bar (5) fit clearance according to claim 1.

6. increment and all kinds of digital display calliper components are general to the right for digital display component according to claim 1.

Technical field:

The present invention relates to a kind of new constructions of slotless round bar depth internal channel digital display calliper, belong to precision machinery processing neck Domain.

Background technique:

Known routine round bar depth internal channel digital display calliper, its defect as shown in Figure 2；

1. mobile feel is not good enough, there is not through slot at main scale (5) back side, sees that C uses fastening screw to figure, main scale (5) and survey seat (3) (4) it fastens, round bar (2) is connect with ruler frame with fastening screw (8), and when attachable mechanical stage frame (11) measurement, round bar (2) is with ruler frame (11) It is moved in main scale (5) slot and survey seat (3) hole, due to main scale (5) slot, the symmetry for surveying seat (3) connection plane and hole machined is flat Row degree accumulated error, when measuring, garden bar (2) often rub with main scale (5) slot and survey seat (3) hole, will have a direct impact on ruler Feel when frame (11) traverse measurement；

2. round bar (2) shaking volume is big, in order to improve feel, often slot is widened, Kong Fang great to meet mobile feel, but It is exaggerated groove width and aperture, round bar (2) shaking volume just becomes larger, and directly affects the measurement error of indication；

3. connection reliability is unstable, due to main scale (5) and seat (3) are surveyed, ruler frame (11) is connected with screw respectively with round bar (2) It connects, slightly loose phenomenon easily occurs for collision in transport or use, the stability of measurement accuracy is directly affected, so conventional products Quality stability is very unsatisfactory

4, digital display component is not general, is now several increments to the left, and universal digital display slide calliper rule component is increment to the right.

Summary of the invention:

The present invention devises a kind of new construction slotless round bar depth septal fossula slot number to overcome the defects of background technique Video card ruler, technical characteristic as shown in Figure 1,

In order to improve feel, main scale (2) back side slotless, bar (5) one end in garden processes a plane, and Cheng Banyuan is shown in Fig. 3, is embedded in In ruler frame (7) semi-round groove, with sub- arc welding, semi-round groove has anti-rotation function, convenient for garden bar when assembly and disassembly groove measuring head (6) (5) can be self-locking, in measurement, garden bar (5) and main scale (2) keeps 0.1mm to the gap 0.2mm, and garden bar (5), which is directly put in, surveys seat (4) It is moved in hole, main scale (2) one end processes a symmetry bench rank, sees Fig. 5, it is pressed directly into seat (4) interference fit is surveyed,

In order to reduce the shaking volume of round bar (5), surveys seat (4) hole and narrowed down to round bar (5) fit clearance by conventional 0.3mm 0.1mm；

This slotless round bar depth internal channel digital display calliper, is changed to digital display component (3) increment to the right, thus can be with all kinds of numbers The digital display component of video card ruler is general.

The invention has the advantages that:

The advantages of new construction slotless round bar depth internal channel digital display calliper of the present invention；See Fig. 1

1. structure is simple, eliminate main scale (2) groove milling process, eliminate main scale (2) drilling and tapping process, round bar (5) and Ruler frame (7) back side eliminates drilling and tapping process, eliminates and surveys seat (4) finish-milling concave square slot, and drilling is expanded heavy process, assembled more square Just, connection is more reliable, and ruler frame (7) can unload at any time from main scale (2) tail portion, repairs convenient for decontamination, has saved processing cost；

2. improve the mobile feel of calliper to measure, due to main scale (2) slotless, round bar (5) only survey in (4) holes of seat into Out, it does not rub when round bar (5) is mobile with ruler frame (7) with main scale (2)；

3. improving the stability of calliper to measure precision, round bar (5) is narrowed down to survey seat (4) hole fit clearance by 0.3mm 0.1mm reduces the shaking volume of round bar；

4. certified product rate is greatly improved since structure is simple, with the sub- arc-welding of interference fit and part instead of on main scale (2) Four screws and ruler frame (7) two, back side screw, improve product reliability, appearance is more simple and beautiful；

5. digital display component (3) realization is general, from increment becomes increment to the right to the left originally；

0-100mm is respectively prepared in measurement range；0-125mm, 0-150mm, 0-200mm, 0-300mm, five kinds of specifications.

Specific embodiment

In order to meet the feel quality of product, Fig. 1, the semi-round groove of ruler frame (7) T-slot and embedded garden bar (5) are seen, and survey seat (4) matching hole is all disposably processed with wire cutting respectively, ensure that each hole degree of being parallel to each other precision,

Main scale (2) presses Fig. 5 processing step, and symmetry is less than 0.015mm, is interference fitted with seat matching hole is surveyed, with press pressure Enter, guarantee that cooperation is firm,

Round bar, in non-porous one end one plane of linear cutter, moves cooperation with ruler frame (7) semicircle hole, with sub- arc-welding by Fig. 3 It being welded in slot, the crator higher than mating surface is removed in reconditioning,

Seat (4) amount face will be surveyed after mechanical parts assembly to stand up on plate, attachable mechanical stage frame (7) makes garden bar (5) while touching flat Plate tightens fastening bolt (13), and fine grinding rod support (4) is then clamped on the fixture of Special grinding amount face and measures face, is being ground again after mill It is ground on plate, flatness 0.006mm, can guarantee round bar (5) contact surface in this way and surveys seat (4) amount face in the same plane,

After mechanical parts processing is qualified, with double faced adhesive tape capacitive grating (10), the veneer (11) of included adhesive sticker is sticked, with self tapping spiral shell (12) are followed closely by dress digital display component (3).
