Abstract
The utility model relates to a kind of novel deep hole internal diameter measuring instrument, and it is primarily of knob, vernier adjustment knob, micrometric screw, micrometering head, nut, torsion spring, micrometering anvil, sleeve composition.Described knob and the coaxial layout of vernier adjustment knob by click anatomical connectivity; Vernier adjustment knob inside is ratchet-wheel gear; Knob and sleeve are threaded connection; Micrometering screw rod, torsion spring, micrometering anvil are installed in micrometering head, and micrometering head and sleeve are by being welded as a whole; Micrometering anvil is engaged with micrometering screw Precise by the micro-screw thread on micrometering screw rod.The utility model can measure solid of revolution internal diameter, deep hole and stepped hole internal diameter; Higher to the measuring accuracy of deep hole and stepped hole, structure is simple, easy to operate.
Description
Technical field
The utility model relates to a kind of novel deep hole internal diameter measuring instrument, can measure the measurer of solid of revolution internal diameter, deep hole and stepped hole internal diameter, belong to surveying instrument technical field.
Background technology
The general internal diameter adopting the inner measuring jaw of vernier caliper to measure solid of revolution at present, its degree of depth that can measure is by the impact of inner measuring jaw height.When measured hole is in darker position, the inner measuring jaw of vernier caliper cannot arrive, and can not measure.For some stepped holes, measurement inlet diameter is little and measured hole diameter large, and the inner measuring jaw of vernier caliper cannot by the aperture measuring measured hole of import.Therefore this metering system can not meet the measurement requirement to deep hole and stepped hole.
Summary of the invention
The purpose of this utility model to measure the deficiency of deep hole and stepped hole, provides a kind of novel deep hole internal diameter measuring instrument, can realize the measurement to deep hole and stepped hole, and easy to operate, and precision is higher.
The technical solution adopted in the utility model is:
A kind of novel deep hole internal diameter measuring instrument of the utility model, primarily of knob, vernier adjustment knob, micrometric screw, micrometering head, nut, torsion spring, micrometering anvil, sleeve composition.Described knob and the coaxial layout of vernier adjustment knob by click anatomical connectivity; Vernier adjustment knob inside is ratchet-wheel gear; Knob and sleeve are threaded connection; Micrometering screw rod, torsion spring, micrometering anvil are installed in micrometering head, and micrometering head and sleeve are by being welded as a whole; Micrometering anvil is engaged with micrometering screw Precise by the micro-screw thread on micrometering screw rod, and nut is placed in micrometering head (4) left side.
During measurement, by the knob of the micrometer inside caliper that turns clockwise, drive micrometric screw rotates, micrometric screw is outwards moved by dynamic three the micrometering anvil footpaths of taper thread subband, measure cambered surface until micrometering anvil to be bearing on tested part inside diameter surface and after basic fixed position, regulate vernier adjustment knob to be finely tuned accurate location, read the composite reading of sleeve outer wall main scale and the secondary chi of knob outer wall.After completing, be rotated counterclockwise knob, micrometering anvil radial direction under the elastic force effect of torsion spring is return, and prepares for measuring different inner diameters solid of revolution next time.
Advantage of the present utility model: 1, the utility model can measure solid of revolution internal diameter, deep hole and stepped hole internal diameter; 2, higher to the measuring accuracy of deep hole and stepped hole, structure is simple, easy to operate.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of novel deep hole internal diameter measuring instrument of the utility model;
Fig. 2 is Fig. 1 left view;
Fig. 3 is taper thread figure of the present utility model.
In figure, 1. knob, 2. vernier adjustment knob 3. micrometric screw, 4. micrometering head, 5. nut, 6. torsion spring, 7. micrometering anvil, 8. sleeve.
Embodiment
Below in conjunction with accompanying drawing, this water supply installation is described further.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of novel deep hole internal diameter measuring instrument of the utility model, forms primarily of knob 1, vernier adjustment knob 2, micrometric screw 3, micrometering 4, nut 5, torsion spring 6, micrometering anvil 7, sleeve 8.Described knob 1 is with the coaxial layout of vernier adjustment knob 2 and by click anatomical connectivity; Vernier adjustment knob 2 inside is ratchet-wheel gear; Knob 1 and sleeve 8 are threaded connection; Micrometering screw rod 3, torsion spring 6, micrometering anvil 7 are installed in micrometering 4,
Micrometering 4 and sleeve 8 are by being welded as a whole; Micrometering anvil 7 engages by the micro-screw thread on micrometering screw rod 3 and micrometering screw rod 3 are accurate, and nut 5 is placed on the left of micrometering 4.
Concrete metering system is: micrometer inside caliper is placed in the detected part degree of depth, micrometric screw 3 is driven to rotate by the knob 1 of the micrometer inside caliper that turns clockwise, micrometric screw 3 is three outside shifting movements in micrometering anvil 7 footpath by boring screw pair by the movement transition of micrometric screw 3, measure cambered surface until three micrometering anvils 7 to be supported on after on the tested inside diameter surface of solid of revolution, adjustment knob 1, make micrometering anvil 7 measure cambered surface to move at the radial section in hole, and regulate vernier adjustment knob 2 to be finely tuned accurately location, size up.This adjustment needs repeatedly to carry out several times, with the error reduced artificially and contingency is brought.Read the composite reading on micrometer inside caliper sleeve 8 outer wall and knob 1 outer wall, obtain measured value.After completing, be rotated counterclockwise knob 1, micrometering anvil 7 radial direction under the elastic force effect of torsion spring 6 is return, and prepares for measuring different solid of revolution internal diameter next time.
