Description
Technical Field
The utility model relates to a clamp, in particular to a multi-section non-contact pneumatic outer diameter gauge.
Background
With the gradual improvement of market industrialization and the rapid development of economy and the continuous improvement of the requirements of modern people on working cost, efficiency and quality, the precision and quality requirements of the machine manufacturing industry on the equipment parts are higher and higher. Some shaft workpieces with higher requirements on precision usually require the outer diameter of the shaft workpieces to be detected after being machined, because the shaft workpieces are precision workpieces, the abrasion of the shaft workpieces to the workpieces is reduced as much as possible, and if manual detection is adopted, the efficiency is low, and the shaft workpieces are easier to abrade; if the non-contact detection of the photo is adopted, in the prior art, the clamp often blocks light, which causes detection errors.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a movable multi-section non-contact pneumatic outer diameter gauge which is reasonable in structural design, simple to operate and convenient to use.
The purpose of the utility model is realized as follows: the multi-section non-contact type pneumatic outer diameter gauge comprises a base, wherein a moving block is arranged on the base, a V-shaped groove is arranged in the moving block, an air outlet hole is formed in the side edge of the moving block, air inlet holes are formed in two sides of the moving block and connected with an air pipe, and the air pipe is connected to a special pneumatic measuring instrument to perform measuring work.
As a further preferable aspect of the present invention, at least one moving block is provided on the base.
As a further preferable aspect of the present invention, a sliding groove is provided on the base.
As a further preferable aspect of the present invention, the moving block is disposed in the sliding groove and is horizontally movable in the sliding groove.
As a further preferable scheme of the utility model, the air outlet is an open type groove which is transversely inwards arranged on the moving block.
Compared with the prior art, the utility model has the following beneficial effects: the utility model discloses a multi-section non-contact pneumatic outer diameter gauge which comprises a base, wherein a V-shaped moving block is arranged on the base, and a plurality of workpieces with the same detection size or different detection sizes can be placed in the V-shaped groove; all moving blocks need to be connected with air pipes and connected to a special pneumatic measuring instrument for measuring; the utility model has reasonable structural design, simple operation and convenient use, and can carry out simultaneous measurement on a plurality of positions of the part of the shaft to be detected in the corresponding V-shaped groove and freely adjust the position according to the length of the shaft; the device has the advantages of high precision, high efficiency and cost saving, and is matched with a special pneumatic measuring instrument to realize automatic acquisition and data storage.
Drawings
In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings needed to be used in the technical descriptions of the embodiments will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art to obtain other drawings based on these drawings without creative efforts.
FIG. 1 is a schematic view of the structure of the present invention.
Fig. 2 is a schematic view of fig. 1A.
The device comprises a base 1, a moving block 2, an air outlet 3, an air inlet 4, an air pipe 5, a sliding groove 6 and a V-shaped groove 7.
Detailed Description
The technical solutions in the embodiments of the present invention are clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without creative efforts, shall fall within the protection scope of the present invention.
As shown in fig. 1-2, the multi-section non-contact pneumatic outer diameter gauge comprises a base 1, wherein a moving block 2 is arranged on the base 1, a V-shaped groove 7 is arranged in the moving block 2, an air outlet hole 3 is arranged on the side edge of the moving block 2, air inlet holes 4 are arranged on two sides of the moving block 2, the air inlet holes 4 are connected with an air pipe 5, and the air pipe 5 is connected to a special pneumatic measuring instrument for measuring.
Preferably, at least one moving block 2 is arranged on the base 1.
Preferably, a sliding groove 6 is arranged on the base 1.
Preferably, the moving block 2 is arranged in the sliding groove 6 and can move horizontally in the sliding groove.
Preferably, the air outlet 3 is an open type groove which is transversely and inwards arranged on the moving block 2.
The first embodiment is as follows:
as shown in fig. 1 and 2, a measured part of a workpiece is placed in a V-shaped groove 7, gas enters from a gas pipe 5, the gas enters into a moving block 2 from an inlet hole 4 to a gas outlet hole 3, the measured part of the workpiece placed on the V-shaped groove 7 is impacted by the gas coming out of the gas outlet hole 3, so that the gas flow coming out of the gas outlet hole 3 forms pressure, and due to the arrangement of a pressure sensor, an electric signal is converted into a numerical signal to obtain a measured value of the measured workpiece.
Example two:
as shown in fig. 2, it can be seen that the air outlet 3 is an open channel, and is transversely disposed on the moving block 2, a gap is formed between the V-shaped groove on the side of the channel and the channel, and the gap is used to enable the entering air to impact on the workpiece to be measured to form pressure, and the signal is converted by a control chip such as a built-in sensor, so as to obtain the final diameter value of the workpiece to be measured to be collected.
