Description
Technical field
The utility model relates to mechanical detection instrument, and more particularly, it relates to a kind of eccentric bushing excircle eccentricity amount detecting device.
Background technology
Eccentric bushing is widely used in mechanically, to reach certain specific matching requirements; The detection method of existing eccentric bushing excircle eccentricity amount is, with vernier caliper repeated measurement eccentric bushing wall thickness, finds maximum thickness and minimum value, by calculating offset according to vernier caliper reading.This method needs repeated measurement, and Measuring Time is long, and the outer round dot detected is discontinuous, is difficult to accurate maximizing and minimum value, detects data out of true, so carry out auxiliary detection in the urgent need to the simple and easy effective pick-up unit of one.
The survey instrument of the eccentric bushing excircle eccentricity amount applied in prior art, has following shortcoming:
1, conventional vernier caliper detects, and check point is discontinuous, is difficult to accurate maximizing and minimum value, so be difficult to find maximum offset.
2, need repeated measurement in operation, minimum and maximum value could be found as far as possible.Time for measuring is many.
3, the data error detected is also large, and testing accuracy is low, and efficiency is low, and operation is also inconvenient.
Utility model content
The technical problems to be solved in the utility model is the above-mentioned deficiency for prior art, provides a kind of structure simple, easy to operate, and measurement data precisely and the high a kind of eccentric bushing excircle eccentricity amount detecting device of efficiency.
The technical solution of the utility model is such: a kind of eccentric bushing excircle eccentricity amount detecting device, comprise cubing seat, through hole is provided with in the middle part of described cubing seat, described through hole is provided with the rotating dog suitable with eccentric bushing to be measured, this rotating dog bottom is plugged in described through hole, is provided with bearing outside described rotating dog, and described bearing is provided with dial gauge, the table bar gauge head of this dial gauge is relative with the axial line of described rotating dog, and described rotating dog top is provided with the rotary handle be fixedly connected with it.
As further improvement, described cubing block hole axial line overlaps with described rotating dog axial line, guarantees higher right alignment, improves testing accuracy.
Further, described bearing is in the circular boss upwards extended with described cubing seat arranged concentric and from cubing seat end face.
Further, described bearing and cubing seat are the integrative-structure of global formation, optimize technique, are convenient to manufacture.
Further, described bearing is provided with mounting hole, and the table bar of described dial gauge is fixed by trip bolt through after this mounting hole, in detection operation, guarantees the stability of testing process.
Beneficial effect
Eccentric bushing excircle eccentricity amount detecting device of the present utility model, novel structure, practical, mainly have the following advantages:
1, can the cylindrical of continuous coverage eccentric bushing, rotary handle rotates can maximizing and minimum value once week, guarantees accurately to find maximum offset.
2, adopt this device to measure, operating speed is fast, and efficiency is high, and accuracy rate is high.
3, by conversion rotating dog, the offset of the eccentric bushing of different inner diameters can be measured, improve the appropriate of this device.
4, this apparatus structure is simple, makes easily, and easy and simple to handle.
Accompanying drawing explanation
Fig. 1 is the cut-open view of this pick-up unit;
Fig. 2 is the vertical view of this pick-up unit.
In figure: 1-cubing seat, 2-rotary handle, 3-rotating dog, 4-trip bolt, 5-dial gauge, 6-bearing, 7-eccentric bushing.
Embodiment
Below in conjunction with the specific embodiment in accompanying drawing, the utility model is described further.
Consult shown in Fig. 1, Fig. 2, a kind of eccentric bushing excircle eccentricity amount detecting device of the present utility model, comprise cubing seat 1, establish through hole in the middle part of described cubing seat 1, described through hole is provided with the rotating dog 3 suitable with eccentric bushing 7 to be measured, this rotating dog 3 bottom is plugged in described through hole, in actual measurement process, rotating dog 3 can flexible rotating in through hole, and the rotating dog 3 of other specifications replaceable, be convenient to the eccentric bushing detecting different inner diameters, improve relevance grade; Establish bearing 6 outside rotating dog 3, and on bearing 6, be provided with dial gauge 5, the table bar gauge head of dial gauge 5 is relative with the axial line of rotating dog 3, the more convenient like this highs and lows finding out eccentric bushing 7; The table bar gauge head surface of described dial gauge 5 contacts with eccentric bushing 7 cylindrical be enclosed within the middle part of rotating dog 3, and pressure table certain size, be convenient to dial gauge check and correction zero graduation, internal thread hole is established on rotating dog 3 top, and be fixedly connected with one section of external thread of rotary handle 2 one end being " L " structure, use convenient for assembly; And bearing and cubing seat are the integrative-structure of global formation, more optimize technique, be convenient to processing and manufacturing.
The present embodiment is in practical operation use procedure, cubing seat 1 level is placed on verifying bench, rotating dog 3 is set with eccentric bushing 7 and is inserted in cubing seat 1 through hole, rotary handle 2 is suitably tightened on rotating dog 3, rotate rotating dog 3, owing to have employed clearance fit, so rotating dog 3 can flexible rotating continuously on cubing seat 1, and can not occur to turn partially, swing or the phenomenon such as stuck; Bearing 6 is installed dial gauge 5, and dial gauge 5 is sleeved in the mounting hole of bearing 6, and the table bar gauge head of dial gauge 5 is contacted with eccentric bushing 7 cylindrical, and pressure table 1mm, meanwhile, lock dial gauge 5 with trip bolt 4; Manual switching rotary handle 2, makes rotating dog 3 and eccentric bushing 7 rotate continuously on cubing seat 1, now, observes dial gauge 5 reading dial, and records maximal value and minimum value, calculate the excircle eccentricity amount of actual measurement eccentric bushing 7, complete detection; This device is easy and simple to handle, and detection efficiency is high, and accuracy is high.
Above-described is only preferred implementation of the present utility model, should be understood that for a person skilled in the art, under the prerequisite not departing from the utility model structure, can also make some distortion and improvement, these all can not affect effect and the practical applicability of the utility model enforcement.
