Description

Simple tool for rapidly testing large aperture

Technical Field

The utility model relates to a machinery processing technology field especially relates to a simple and easy frock in the great aperture of quick test.

Background

In the machining production, especially in the machining of automobile molds, some holes with the diameter of D20mm to D120mm are common. For these larger bore holes, the test is usually performed by manually rotating a caliper to find the maximum inner diameter. The test mode is not only slow, but also the accuracy of the measurement result depends on the patience and the careful degree of the measuring personnel, and the caliper test mode has the problems of inconvenient operation and even processing potential safety hazard when the hole needs to be tested in the processing process so as to be corrected in the processing.

Disclosure of Invention

An object of the utility model is to provide a simple and easy frock of the great aperture of quick test to solve above-mentioned problem.

In order to achieve the above purpose, the utility model adopts the technical scheme that: the utility model provides a simple and easy frock in quick test great aperture, includes scale rod, bracing piece and measuring stick, the scale has on the scale rod, the cover is equipped with the index piece on the scale rod, scale rod and index piece sliding connection, be provided with the sliding groove on the index piece, the bracing piece passes through sliding groove and index piece sliding connection, the index piece is connected through the pivot with the measuring stick, the bracing piece also passes through the hub connection with the measuring stick, the end of measuring stick is provided with the measurement ball, the end of scale rod is provided with the gravity ball.

The utility model discloses a measuring stick constitutes evenly distributed's trilateral jointly with bracing piece and scale bar to the aperture test is carried out to the measurement principle that adopts the cross-section circle, and the bracing piece remains the horizontal slip throughout, and in the level with the scale bar equidistance.

As a preferred technical scheme: and the index block is provided with a locking screw rod for locking the index block. So as to lock the reading and make the reading more stable and accurate.

Compared with the prior art, the utility model has the advantages of: by adopting the tool, the whole test process can be completed only by two steps of putting and pushing, the structure is simple, the use is convenient, the test time is greatly saved, and the test efficiency is improved; particularly, when traditional slide caliper rule surveyed the great aperture, need ensure to measure and just can guarantee for the maximum dimension that the measuring result is the diameter value in hole, this process relies on measuring personnel's experience seriously, and about 1 to 5 minutes vary in time-consuming, and adopt the utility model discloses a frock carries out the aperture and measures, and frock self structure has just directly guaranteed that the measured result is the diameter value in hole, measures about 10 to 30 seconds in time-consuming, and test efficiency has improved 2 times at least.

Drawings

Fig. 1 is a side view of an embodiment of the present invention;

fig. 2 is a top view of an embodiment of the present invention;

fig. 3 is a schematic view of an embodiment of the present invention in use.

In the figure: 1. a graduated rod; 2. an index block; 3. locking the screw rod; 4. a support bar; 5. a measuring ball; 6. a measuring rod; 7. a gravity ball.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

Example (b):

referring to fig. 1-2, a simple tool for rapidly testing a large aperture comprises a scale rod 1, a support rod 4 and a measuring rod 6, wherein scales are arranged on the scale rod 1, an index block 2 is sleeved on the scale rod 1, the scale rod 1 is slidably connected with the index block 2, a sliding groove is formed in the index block 2, the support rod 4 is slidably connected with the index block 2 through the sliding groove, the index block 2 is connected with the measuring rod 6 through a shaft, the support rod 4 is also connected with the measuring rod 6 through a shaft, a measuring ball 5 is arranged at the tail end of the measuring rod 6, and a gravity ball 7 is arranged at the tail end of the scale rod 1;

in the embodiment, the number of the support rods 4 and the number of the measuring rods 6 are four, each support rod 4 is equal in length horizontally and distributed in a cross shape in the horizontal plane, and each measuring rod 6 (including the measuring ball 5) has the same specification, so that the measuring principle of the section circle is ensured;

when the hole diameter measuring device is used, referring to fig. 3, firstly, a measuring tool is placed into a hole to be measured, the measuring tool is placed to a depth until a measuring ball 5 enters the hole, the upper end of a scale rod 1 is held by a hand to push an index block 2, under the supporting action of a supporting rod 4, a measuring rod 6 is opened, in the pushing process, a sliding groove on the index block 2 is always kept in sliding fit with the supporting rod 4, so that the supporting rod 4 is always kept horizontal, the index block 2 is continuously pushed until the measuring ball 5 contacts the inner wall of the hole, under the action of always keeping horizontal support of the supporting rod 4, the index block 2 is pushed still, namely the index block 2 is pushed in place, and the scale on the scale rod 1 corresponding to the upper edge of the index block 2 is the aperture value of the measured;

after the index block 2 is pushed to the right position, the locking screw 3 on the index block 2 can be selected to be rotated to lock according to requirements so as to lock the reading;

the whole testing process can be completed only by putting and pushing two steps, so that the testing time is greatly saved, and the testing efficiency is improved.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
