Abstract

The utility model discloses an angle measuring device, which comprises a dial and an indication assembly. The indication assembly comprises a heavy bob and an indicator which are connected through threads. The indication assembly is in clearance fit with the dial through an M8 bolt. By means of the technical scheme, angle measuring work saves labor and is high in efficiency due to the fact that gravity principle is utilized. In addition, the dial and the indication assembly are made of steel materials and connected into a whole to achieve the effect that the angle measuring device is stable in location in measurement and long in service life. Simultaneously, the measuring device is small in size, fixing assemblies are not needed to replace frequently, and measuring angles of the device meet requirements of a plurality of kinds of parts, thereby achieving universal effect.

Description

Angle measurement unit

Technical field

The utility model relates to the diesel engine field, particularly a kind of angle measurement unit.

Background technology

In the assembling process of diesel engine, comprise the operation that some takes measurement of an angle.The measuring method of using at present is to utilize the common plastics protractor to be placed on the parts that need detection roughly to confirm its angle through range estimation.The measuring error of this method is quite big, and requires the angle of specifying parts is carried out strictness control according to some specific user, and the method can't reach these requirements at all.In addition, common protractor does not have the device of indicating graduation, leans on naked eyes absolutely to estimate inefficiency, and efficiency of assembling and assembly quality are not high.Secondly, common protractor material is plastics, and scale is easy to take off under long-time the use, is very easily scratched or damages, and serviceable life is very short.

The utility model content

The purpose of the utility model is the angle measurement unit that provides a kind of efficiency of assembling and assembly quality all high.Pointer relies on bottom thread to be installed in the weight upper screwed hole, is combined into indication component.0 ° of groove and 90 ° of grooves intersected at and decided the hole circle heart on the index dial, and pointer can accurately be indicated angle when guaranteeing to measure.Indication component is decided the hole through the M8 screw through the mistake on the index dial and is formed clearance fit with it, makes pointer under action of gravity, pass through to decide the hole circle heart, thereby indicates angle straight up.

The technical solution of the utility model is such, and a kind of angle measurement unit comprises: index dial and indication component, it is characterized in that the screw thread (6) of pointer (4) connects the threaded hole (7) of weight (2), and weight (2) is connected with bolt (3) with index dial (1).Gapped between weight (2) and the index dial (1).The last 0 ° of groove of index dial (1) and 90 ° of grooves intersected at decides the hole circle heart (5).Index dial (1) and weight (2) pass to cross on the index dial through bolt (3) to be decided the hole circle heart (5) and is connected.

The advantage of the utility model: owing to utilized gravity principle, the work that takes measurement of an angle is laborsaving and efficient is high, in addition; Index dial and indication component adopt steel material and connect as one, and be permanent to reach when measuring positioning stablity and life-span, simultaneously; This measurement mechanism volume is less; Fixation kit needn't often be changed, and taking measurement of an angle of device is applicable to and the requirement of multiple parts can reaches common effect.

Embodiment

Below in conjunction with accompanying drawing, specific embodiments of the invention is described in detail, but is to be understood that protection scope of the present invention does not receive the restriction of embodiment.

With reference to Fig. 1～Fig. 6, this angle measurement unit comprises: index dial 1 and indication component and M8 bolt 3, indication component comprise weight 2 and pointer 4.There is the M4 screw thread pointer 4 bottoms to tighten M4 threaded hole on weight.Pointer 4 bottoms have screw thread 6 to be connected with the threaded hole 7 of weight 2, and weight 2 and index dial 1 pass to cross on the index dial through bolt 3 to be decided the hole circle heart 5 and be connected.

As shown in Figure 2, index dial 1 high scale is accurate to 1 ° of every lattice, with the degree of accuracy that guarantees to measure.0 ° of groove and 90 ° of grooves intersected at and decided the hole circle heart 5 on the index dial 1, and pointer can accurately be indicated angle when guaranteeing to measure, and the number of degrees are accurately quick, thereby guaranteed efficiency of assembling.

Referring to Fig. 1, Fig. 4, Fig. 5 and Fig. 6; Be processed with M8 threaded hole 8 on the weight 2, M8 bolt 3 passed index dial 1 decide excessively to realize in the M8 threaded hole 8 on the hole circle heart precession weight 2 reliable the connection, form clearance fit simultaneously; Make between weight 2 and the index dial 1 gapped; Make pointer 4 under action of gravity, pass through to decide the hole circle heart 5, thereby indicate angle straight up, guarantee assembly quality.The center of gravity of weight 2 and pointer 4 makes the vertical direction indication angle of pointer 4 along gravity in same plane.0 ° of groove and 90 ° of grooves intersected at and decided the hole circle heart 5 on the index dial 1, and pointer can accurately be indicated angle when making measurement.Index dial 1 and weight 2 pass index dial 1 through bolt 3 and cross and decide the hole circle heart 5 and be connected, and make pointer 4 under action of gravity, pass through to decide the hole circle heart 5, thereby indicate angle.

Whole device has utilized gravity principle; Device is indicated angle value automatically when realizing measuring; Make the work of taking measurement of an angle laborsaving and efficient is high, in addition, index dial 1 adopts steel material with indication component and connects as one; Precision reaches 1 ° of one lattice, and is permanent to reach positioning stablity when measuring, reliable results and life-span.Simultaneously, this measurement mechanism volume is less, is convenient for carrying, and does not receive the limitation in space, and fixation kit needn't often be changed, and device is applicable to the measurement of angle requirement of multiple parts, can reach common effect.And pointer 4 is to utilize the transformation of the way of M4 screw, reduces cost of manufacture.

More than the disclosed specific embodiment that is merely the utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into the protection domain of the utility model.
