Abstract
A kind of special measuring tool examining and determine vernier caliper, its structure is: on base, be vertically provided with support, jacking gear is rack-mount, the fixture of level is installed on the top of jacking gear, fixture is provided with special-shaped block, described special-shaped block is provided with and is more than or equal to 2 and is arranged in order and the through hole be evenly distributed, base has also been arranged side by side two gauge blocks, and the distance of two gauge blocks is the width of vernier caliper depth survey bar.The utility model adopts said structure, by arranging special-shaped block with on the support of base, and use jacking gear to adjust the height of special-shaped block, solve exist in prior art due to the multiple gauge block of a secondary use, multiple gauge block is measured and the longevity of service produced, ineffective technical matters.The utility model can replace multiple gauge block by a surveying instrument, shortens the calibrating time, improves work efficiency.
Description
Technical field
The utility model relates to a kind of calibrating special measuring tool, especially a kind of special measuring tool examining and determine vernier caliper.
Background technology
At present, in the verification process of vernier caliper, generally use gauge block as its measurement standard.When examining and determine, measure inner measuring jaw and outer measuring jaw respectively, the vernier caliper with depth survey bar also will carry out the calibrating of the degree of depth error of indication.The gauge block of different size will be chosen when carrying out inner measuring jaw and outer measuring jaw and measuring, often to constantly choose and adjust gauge block and just can obtain measurement result, vernier caliper such as more than 300mm needs to gather at least 6 measurement points, need at least to prepare 6 pieces of gauge blocks to measure, time required for measurement is longer, and work efficiency is lower.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of special measuring tool examining and determine vernier caliper, by arranging special-shaped block with on the support of base, and use jacking gear to adjust the height of special-shaped block, multiple gauge block can be replaced by a surveying instrument, solve exist in prior art due to the multiple gauge block of a secondary use, multiple gauge block is measured and the longevity of service produced, ineffective technical matters.
To achieve these goals, the technical solution used in the present invention is: a kind of special measuring tool examining and determine vernier caliper, it is characterized in that: on base, be vertically provided with support, jacking gear is rack-mount, the fixture of level is installed on the top of jacking gear, fixture is provided with special-shaped block, described special-shaped block is provided with and is more than or equal to 2 and is arranged in order and the through hole be evenly distributed, base has also been arranged side by side two gauge blocks, and the distance of two gauge blocks is the width of vernier caliper depth survey bar.
Described support has vertical rectangular fixed orifice.
Described jacking gear is a concave metal plate being enclosed within rack outer surface, is provided with the position bolt corresponding with fixed orifice in the bottom of jacking gear, and the screw portion of bolt, through through hole, is fixed on support by nut screwing clamping.
The beneficial effects of the utility model are: the utility model adopts said structure, by arranging special-shaped block with on the support of base, and use jacking gear to adjust the height of special-shaped block, solve exist in prior art due to the multiple gauge block of a secondary use, multiple gauge block is measured and the longevity of service produced, ineffective technical matters.The utility model can replace multiple gauge block by a surveying instrument, shortens the calibrating time, improves work efficiency.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
A kind of special measuring tool examining and determine vernier caliper as shown in Figure 1-2, is characterized in that: on base 5, be vertically provided with support 4, jacking gear 3 is arranged on support 4, is provided with the fixture 2 of level, fixture 2 is provided with special-shaped block 1 on the top of jacking gear 3.As shown in Figure 3, special-shaped block 1 is provided with and is more than or equal to 2 and is arranged in order and the through hole 7 be evenly distributed, in this example, adopt the special-shaped block of 6 through holes 7.The distance that base 5 has also been arranged side by side two gauge blocks, 6, two gauge blocks 6 is the width of vernier caliper depth survey bar.Support 4 has vertical rectangular fixed orifice 8.Jacking gear 3 is a concave metal plate being enclosed within support 4 outside surface, is provided with the position bolt corresponding with fixed orifice 89 in the bottom of jacking gear 3, and the screw portion of bolt 9, through through hole 8, is tightened on support 4 by nut 10.
In use, first adjust the height of jacking gear 3, will highly determine that tightening nut 10, makes bolt 9 apply pressure to jacking gear 3, be fixed on support 4 by jacking gear 3 on the height that testing person's work is comparatively comfortable.When examining and determine the outer measuring jaw of vernier caliper, two outer measuring jaws being measured the outside dimension that special-shaped block 1 provides, completes the calibrating of outside dimension.When examining and determine the inner measuring jaw of vernier caliper, two inner measuring jaws being measured the inside dimension that special-shaped block 1 provides, completes the measurement of inside dimension.When the depth survey bar of vernier caliper is examined and determine, directly depth survey bar is inserted the gap between two gauge blocks 6, its degree of depth is measured, complete the measurement to the degree of depth.
