Background technique

Outside micrometer is the measurement instrument taken measurements for measuring the geometry such as length, diameter, thickness, wherein (0~100) Outside micrometer within the scope of mm is divided into tetra- kinds of (0~25) mm, (25~50) mm, (50~75) mm, (75~100) mm specifications, It is widely used in all trades and professions, according to JJF21-2008 " micrometer " vertification regulation, the micrometer error of indication of every kind of specification is adopted It is calibrated with one group of 5 pieces of various sizes of gauge block, every piece of gauge block must be clamped from gauge block box with clip when calibration, every to survey one It is a, it needs back and forth to clamp once, daily repeated multiple times clamping gauge block, personnel's finger is aching and tired, and there is the wind for colliding with, dropping Danger, operating process is cumbersome, and time of measuring is long, and efficiency is lower.

Utility model content

In order to overcome repeated multiple times clamping gauge block in outer diameter micrometer indication error calibration, finger is aching and tired, operates Journey is cumbersome, and time of measuring is long, the defect of low efficiency, and the utility model provides a kind of calibration outside micrometer auxiliary device, leads to Simple operations are crossed, outer diameter micrometer indication error calibration can be once completed.

The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of calibration outside micrometer auxiliary dress It sets, it is characterised in that: including pedestal, square column, fixed bracket, bearing box, gauge block frame, the lower end of square column passes through bolt It is fixed with pedestal, upper end is mounted on the base by fixed bracket, in two bearing boxes of each side installation of square column, Each bearing box is connect by hinge with square column, and bearing box can surround hinge axis, is inlaid with gauge block frame in bearing box, Handle is installed in the front end face of bearing box.

Fluted among the pedestal lower part, width is greater than square column width, and two are uniformly provided in groove and is led to Hole, base rear portion are equipped with a screw hole.

The support bracket fastened both ends are respectively provided with a through-hole.

There are two screw holes for the square column lower end setting, are fixedly connected by two the first bolts with pedestal, upper end is set There is a screw hole, is fixedly connected by fixed bracket, the second bolt, third bolt with pedestal.

The bearing box is mounted on square column by 8 hinges and 32 screws, and there are two on each side is distributed in upper and lower, Front end is equipped with handle by the first fastening screw, bearing box can be made around hinge axis, the handle both ends by handle There is the second connecting hole, centre is arc surface.

There are two joint faces for the hinge, and there are also hinge axis, there are two the first connecting holes for each hinge joint face.

There are four types of specifications for the gauge block frame corresponding amount block size, are embedded in four bearing boxes respectively, the gauge block frame is adopted It is composed with wood materials, shares 5 step surfaces, corresponding amount block size is provided with corresponding groove in each step surface.

The beneficial effects of the utility model are: the utility model is using the above structure, gauge block is put into recessed in gauge block frame Primary by handle rotation bearing box in slot, i.e., available outside micrometer measures 5 pieces of different size gauge blocks, completes outer Diameter micrometer error of indication calibration, the utility model structure is simple, easy to operate, has saved gauge block placement space, solves Clamp gauge block repeatedly in the prior art, finger is aching and tired, and there is the risk collided with, dropped, and mitigates person works intensity, contracting Short measurement non-cutting time improves working efficiency.

Specific embodiment

It is described in further detail below in conjunction with citing shown in attached drawing.

As shown in Figure 1 and Figure 2, a kind of calibration outside micrometer auxiliary device, including pedestal 1, square column 5, fixed branch The lower end of frame 6, bearing box 2,3,7,8, gauge block frame 12, square column 5 is fixedly connected by two the first bolts 9 with pedestal 1, Upper end passes through fixed bracket 6 and the second bolt 10, third bolt 11 are mounted on pedestal 1, and bearing box 2,3,7,8 passes through 8 hinges Chain 4 and 32 screw 18 is mounted on the two sides of square column 5, and there are two on each side in distribution up and down, and can surround 17 turns of hinge axis It is dynamic, it is inlaid with the gauge block frame 12 an of specification in each bearing box, there are 5 grooves 14 in gauge block frame 12, respectively corresponds different rulers Very little gauge block, each handle 13 are mounted on the front end face of bearing box by two the second fastening screws 20.

In use, choosing (0~25) mm, the gauge block of two kinds of specifications of (25~50) mm is respectively put into bearing box 3 and bearing box In 7 gauge block frame groove, (50~75) mm is chosen, the gauge block of two kinds of specifications of (75~100) mm is respectively put into bearing box 2 and holds In the gauge block frame groove for carrying case 8, according to the outside micrometer measurement range of required calibration when measurement, corresponding one group of amount is chosen The bearing box is rotated to positive operating position by the handle of bearing box front end by block, then with outside micrometer to the carrying 5 pieces of gauge blocks in case measure respectively, after measurement, the bearing box are rotated to side standby position by handle, i.e., Achievable outer diameter micrometer indication error calibration, the utility model device is easy to operate, without frequently clamping gauge block, shortens Non-cutting time is measured, person works' intensity is mitigated, improves working efficiency.
