The base is used as a measuring plane, a perpendicular mandrel is arranged on the base and used for fixing a measured bearing, each pressing block is provided with a semicircular notch, a round hole is formed after the two pressing blocks are oppositely combined with each other, a through hole is arranged on one side of each pressing block, a threaded hole is disposed on the other side of each pressing block, external threads are arranged at the front end of each measuring bar and match with the threaded hole of the corresponding pressing block, and the micrometer is disposed at the rear end of one of the measuring bars. Compared with the prior art, the bearing inclination angle measuring instrument is more accurate in detection of inclination angles of bearings and smaller in error, can guarantee service performance and the service lives of the produced bearings, greatly improves quality of the finished bearings, is favorable for application and popularization of the bearings, simultaneously enhances production efficiency of an enterprise, also reduces unqualified bearings, and further decreases production cost.

Description

Bearing incline measurement instrument

Technical field

The utility model belongs to bearing detection technique field, especially relates to a kind of bearing incline measurement instrument.

Background technology

The bearing industry of China development in recent years is rapid, and still domestic measuring technique to bearing is also relatively backward, especially lacks the measuring equipment and the relevant measuring method that are used to detect the bearing pitch angle; Because the pitch angle between the inside and outside circle of bearing is in case surpass its allowed band, will make and produce too high extra-stress in the bearing, cause bearing operation precise decreasing, running noise to increase, thereby have influence on the usability of bearing, the serviceable life that also can reduce bearing.

At present, domestic detection to the pitch angle is that outer ring fixed test personnel pin cycle surface with thumb mostly, all the other fingers lift inner ring and determine with sensation, but facts have proved, because different detection persons' gimmick difference, feel different, so the pitch angle that uses this method to detect bearing can produce bigger error amount, flows to market to cause some bearings underproof or poor-performing, has influence on the application and the popularization of product.

The utility model content

To be solved in the utility model is the technical matters that conventional detection can't accurately detect bearing pitch angle numerical value, and a kind of bearing incline measurement instrument is provided.

For this reason, the technical scheme that the utility model adopted is such: bearing incline measurement instrument, comprise a pedestal as measurement plane, and it is characterized in that: pedestal is provided with a vertical mandrel, is used for fixing measured bearing; It also comprises two briquettings and two measuring staffs, and briquetting respectively has semicircular breach, and two involutory backs of briquetting form a circular hole; Briquetting one side has through hole, and opposite side is threaded the hole, and the measuring staff front end has external thread, matches with the threaded hole of briquetting; It also comprises 1,000 fens instrument, is located at the wherein rear end of a measuring staff.

Also be provided with a vertical vertical rod on the described pedestal, instrument was contained in the vertical rod by connecting rod in thousand minutes, and its chaining pin contacts the rear end of described measuring staff.

The utility model places measured bearing on the mandrel earlier when detecting, and is fixed by a check nut; Again two briquettings are encircled measured bearing after involutory, because two briquettings respectively have semicircular breach, fit like a glove with the radian of measured bearing outside surface, so two briquettings can be close to the outside surface of measured bearing, and have externally threaded measuring staff by two front ends and pass a through hole on the briquetting respectively, enter the threaded hole of another briquetting, make two briquettings and measured bearing form interference fit after tightening; Then, adjust thousand fens instrument that are contained on the connecting rod, make the wherein rear end of a measuring staff of its chaining pin contact; Afterwards, just touch a measuring staff of no chaining pin, the measuring staff of chaining pin is also swung up and down thereupon, thereby made thousand fens to demonstrate shift value X on the instrument, and note this shift value X; Then, measure the chaining pin of thousand fens instrument and the distance H at mandrel center; At last, calculate the bearing angle of inclination beta according to formula β=arctan (X/H), just can be with reference to the industry standard at bearing pitch angle, check the bearing pitch angle B standard whether up to specification of institute's measured bearing.In real work, the position of thousand fens instrument, mandrel is generally fixed, and the distance H between them also is a constant value, can accurately be measured, and repeatedly uses.

Compared with prior art, essential distinction of the present utility model be by the surveying instrument that adopts science replace tradition by the testing staff by the detection of subjective judgement to the bearing pitch angle, make the bearing pitch angle more accurate, error is littler, can guarantee the usability of the bearing of producing and use the longevity to use, improve the quality of finished product bearing greatly, helped the application and the popularization of product; Also improve the production efficiency of enterprise simultaneously, also reduced substandard product, further lowered production cost.

Embodiment

Below in conjunction with drawings and Examples the utility model is done further detailed description.

Referring to accompanying drawing.Present embodiment comprises a pedestal 1 as measurement plane, two briquettings 2 and two measuring staffs 3, and described pedestal 1 is provided with a vertical mandrel 4, is used for fixing measured bearing 5; Also be provided with vertical 6, thousand fens instrument 7 of vertical rod on the described pedestal 1 and be contained in the vertical rod 6, the rear end of its measuring staff 3 located therein, the rear end of the above-mentioned measuring staff 3 of its chaining pin 9 contacts by connecting rod 8.Described two briquettings 2 respectively have semicircular breach, and two briquetting 2 involutory backs form a circular hole; Briquetting 2 one sides have through hole, and opposite side is threaded the hole, and measuring staff 3 front ends have external thread, match with the threaded hole of briquetting 2.

Present embodiment places measured bearing 5 on the mandrel 4 earlier when detecting, and is fixed by a check nut 10; Again two briquettings 2 are encircled measured bearing 5 after involutory, because two briquettings 2 respectively have semicircular breach, fit like a glove with the radian of measured bearing 5 outside surfaces, so two briquettings 2 can be close to the outside surface of measured bearing 5, and have externally threaded measuring staff 3 by two front ends and pass a through hole on the briquetting 2 respectively, enter the threaded hole of another briquetting 2, make two briquettings 2 and measured bearing 5 form interference fit after tightening; Then, adjust thousand fens instrument 7 that are contained on the connecting rod 8, make the wherein rear end of a measuring staff 3 of its chaining pin 9 contacts; Afterwards, swing up and down two measuring staffs 3, the chaining pin 9 of thousand fens instrument 7 is shifted up and down with the rear end with its measuring staff that contacts 3, thereby made thousand fens to demonstrate shift value X on the instrument 7, and note this shift value X; Then, measure the chaining pin 9 of thousand fens instrument 7 and the distance H at mandrel 4 centers; At last, calculate the bearing angle of inclination beta according to formula β=arctan (X/H), just can be with reference to the industry standard at bearing pitch angle, check the bearing pitch angle B standard whether up to specification of measured bearing 5.
