Description

A hand-held rapid inspection tool for measuring hole depth

technical field

The utility model relates to the technical field of auto parts and medical equipment production and manufacturing, in particular to a hand-held rapid inspection tool for measuring the diameter of a general aperture or the depth of a hole when the bottom is an inclined plane.

Background technique

In the field of mechanical processing and manufacturing, especially in the auto parts and medical equipment industries, many products have many holes on the surface, and the joints between the holes are inclined. In the past, there were no good measuring tools for testing, and needles were generally used. The combination of a needle gauge and an ordinary caliper or three-coordinate measurement, or projection detection after breaking the ring, although the combination of a needle gauge and an ordinary caliper can measure more accurately, but the detection efficiency is low, and although the three-coordinate and broken ring projection detection has higher measurement accuracy High, but the detection cost is high, the detection efficiency is very low, and it is impossible to realize large-scale, accurate and fast detection, let alone rapid detection on the production site; based on the above reasons, it is necessary to develop new inspection tools to meet the measurement requirements.

Utility model content

The purpose of this utility model is to provide a hand-held rapid inspection tool for measuring hole depth that can realize large-scale, accurate and fast measurement by quickly replacing the measuring needle gauge for different apertures and different depths, so as to solve the problems in the above-mentioned background technology. the question raised.

In order to achieve the above object, the utility model provides the following technical solutions:

A hand-held rapid inspection tool for measuring the depth of a hole, including a meter, a fixed bracket, a sleeve, a measuring needle gauge, a movable block, a locking screw and an auxiliary block for zeroing. The meter is installed on one of the fixed brackets. On the side, the lower part of the fixed bracket is provided with a sleeve, and the measuring needle gauge is installed in the sleeve; the zero-returning auxiliary block is vertically provided with a V-shaped groove. The front end measuring surface of the movable block is located on the same plane as the bottom plane of the movable block.

As a further solution of the utility model: the meter is a dial indicator and a dial indicator.

As a further solution of the utility model: between the sleeve and the fixed support, between the meter and the fixed support, and between the meter and the movable block are all fixed by locking screws.

Compared with the prior art, the beneficial effects of the utility model are: the utility model has a simple structure and a reasonable design, and can realize rapid detection in large quantities; it is suitable for rapid detection on any site; and the measurement of different apertures and depths can be realized by quickly replacing the measuring needle gauge ; The measurement result is intuitive; it greatly saves the inspection time and inspection cost, and has great market promotion value.

detailed description

The technical solution of this patent will be further described in detail below in conjunction with specific embodiments.

Please refer to Figure 1-5, a hand-held quick inspection tool for measuring hole depth, including meter 1, fixed bracket 2, locking screw 3, sleeve 4, measuring pin gauge 5, movable block 6 and zero reset Auxiliary block 7, the meter 1 is installed on one side of the fixed bracket 2, the bottom of the fixed bracket 2 is provided with a sleeve 4, and the measuring needle gauge 5 is installed in the sleeve 4; the vertical reset auxiliary block 7 is provided with V-shaped groove, during zeroing calibration, the bottom surface of the zeroing auxiliary block 7, the front end measuring surface of the measuring needle gauge 5 and the bottom plane of the movable block 6 are located on the same plane.

The meter 1 is a dial indicator and a dial gauge.

Between the sleeve 4 and the fixed bracket 2 , between the meter 1 and the fixed bracket 2 and between the meter 1 and the movable block 6 are all fixed by locking screws 3 .

The working principle of the utility model is: before use, the meter 1, that is, the dial indicator or the dial indicator, needs to be reset to zero. The specific implementation method is to fit the measuring pin gauge 5 and the V-shaped groove of the zeroing auxiliary block 7, Put the bottom surface of the zeroing auxiliary block 7, the front end measuring surface of the measuring needle gauge 5 and the bottom plane of the movable block 6 on the flat plate at the same time, and turn the dial indicator or dial gauge to return the pointer to zero; 2. Measure The needle gauge 5 is inserted into the measured hole 8, and at the same time, the movable block 6 will push the gauge 1, and as the measuring needle gauge 5 is inserted into the bottom of the measured hole 8, the indicator needle on the dial of the gauge 1 will indicate A scale value, and this scale value is the actual depth of the hole 8 to be measured.

The preferred implementation of this patent has been described in detail above, but this patent is not limited to the above-mentioned implementation. Within the scope of knowledge possessed by those of ordinary skill in the art, various modifications can be made without departing from the purpose of this patent. kind of change.
