Description
Technical Field
The utility model relates to a mechanical measurement technical field, in particular to auxiliary measuring device.
Background
With the rapid development of the mechanical industry, the styles of mechanical parts are more and more, and the accompanying difficulties are more and more prominent. For example, when the bore depth is measured with tight tolerance, and a tool is worn and needs to be replaced or the machine tool or the clamp is adjusted, an operator needs to measure the dimension and then perform the adjustment operation of the tool compensation or the machine tool or the clamp. However, due to the fact that the aperture is large, the tolerance is small, the fit clearance between the measuring device and the hole is small, even if the measuring device is placed in the hole, the measuring device is easy to clamp in the hole and is not easy to pull out, the workpiece is likely to be scrapped or the inspection time is too long, production is interrupted, time and labor are wasted, the requirement on operating personnel is high, time is wasted, and production efficiency is reduced.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an auxiliary measuring device solves the measuring device who mentions in the background art and is difficult for putting into downthehole waiting technical problem.
In order to achieve the above object, the utility model discloses an auxiliary measuring device's concrete technical scheme as follows:
the utility model provides an auxiliary measuring device, includes measuring component for measure the degree of depth of waiting to survey the hole on the work piece that awaits measuring, be provided with the guide block on waiting to survey the hole, seted up the guiding hole on the guide block, be connected with measuring component on the guiding hole, thereby measuring component passes the guiding hole and inserts the downthehole aperture degree of depth of waiting to survey the hole that awaits measuring.
Furthermore, the measuring assembly is a tolerance measuring instrument and comprises a positioning mandrel, and the lower end of the positioning mandrel is connected with a cylindrical section.
Furthermore, the bottom of location dabber is provided with the boss, and the boss is connected with the cylinder section.
Further, the lower surface laminating department of boss is provided with the guide block, and the lower surface of boss and the upper surface of guide block contact the laminating setting.
Further, the inner diameter of the guide hole is 0.03mm to 0.1mm larger than the diameter of the cylindrical section.
Further, the clearance between the cylindrical section and the guide hole is 0.05 mm.
Furthermore, the longitudinal sectioning section of the guide block is rectangular, and a guide hole arranged in the center of the guide block is a through hole.
Further, the top angle of the guide block is provided with a round angle.
The utility model discloses an auxiliary measuring device has following advantage: the utility model provides an auxiliary measuring device can be at the tight aperture degree of depth of production site measurement tolerance, and it not only can measure the aperture degree of depth at the first time after on-the-spot operating personnel passes through tool changing, lathe or anchor clamps adjustment, reduces the production time because of measuring the occupation moreover, reduces and measures and manufacturing cost, improves measurement of efficiency.
Drawings
Fig. 1 is a schematic view of the overall structure of the auxiliary measuring device of the present invention;
fig. 2 is a schematic view of the whole structure of the guide block of the present invention.
The reference numbers in the figures illustrate: 1. a guide block; 11. a guide hole; 2. a measurement assembly; 21. positioning the mandrel; 22. a boss; 3. and (6) a hole to be detected.
Detailed Description
In order to better understand the purpose, structure and function of the present invention, an auxiliary measuring device of the present invention will be described in further detail with reference to the accompanying drawings 1-2.
As shown in fig. 1, the utility model provides an auxiliary measuring device for the degree of depth in the hole that measuring tolerance is tight, the aperture is big is provided with guide block 1 on the hole of awaiting measuring 3, has seted up guiding hole 11 on the guide block 1, is connected with measuring component 2 on the guiding hole 11, thereby measuring component 2 passes guiding hole 11 and inserts the aperture degree of depth of waiting to measure hole 3 in waiting to measure hole 3.
The inner diameter of the guide hole 11 is 0.03mm to 0.1mm larger than the diameter of the cylindrical section.
Preferably, the clearance between the cylindrical section and the guide hole 11 is 0.05mm, and the measuring assembly 2 can be easily inserted into the guide hole 11 without causing jamming.
As shown in fig. 2, the longitudinal section of the guide block 1 is rectangular, the guide hole 11 formed in the center of the guide block 1 is a through hole, and the top corner of the guide block 1 is provided with a round corner.
The utility model provides a guide block 1 mainly plays the guide effect to measuring component 2, the utility model provides an embodiment, the hole tolerance that awaits measuring is 0.01mm, and the aperture reaches 21.51mm, and it needs to keep the closed angle with measuring component 2 front end to measure the hole depth, nevertheless does not have the guide, and this measuring component hardly inserts when the hole tolerance that awaits measuring is strict in waiting to measure the hole. The utility model provides a guide block 1 mainly plays the guide effect, when the field measurement, only needs to place guide block 1 on the terminal surface of the hole 3 that awaits measuring, puts into guiding hole 11 with measuring component 2, removes the cylinder section and finds continuing to insert after being surveyed the hole, measuring component 2 inserts and to await measuring downthehole back can the measuring hole dark.
The angle between the end face of the hole to be measured 3 and the end face of the guide hole 11 is ensured by a machine tool and a clamp, and in the normal machining process, the error can be ignored, so that the reason that the measuring component 2 is not easy to be placed into the hole to be measured or clamped in the hole to be measured is that the measuring component 2 cannot be vertically placed. During the use, put guide block 1 on the terminal surface of being surveyed the hole, just can guarantee that guide hole 11 is vertical with the hole that awaits measuring, like this when measuring component 2 inserts this guide block 1, just can guarantee that measuring component 2 is vertical, avoid handheld measuring component 2 not vertical to cause the jamming.
It is to be understood that the present invention has been described with reference to certain embodiments, and that various changes or equivalents may be substituted for elements thereof by those skilled in the art without departing from the spirit and scope of the invention. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from the essential scope thereof. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of the present application are intended to be covered by the present invention.
