Specific embodiment

It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further Description, but the utility model is not limited to these examples.

As shown in Figure 1 and Figure 2, a kind of fixture for main shaft detection, comprising: fixing seat 100, conflict block 200, end folder Seat and movable grip slipper are held, the end grip slipper, the conflict block 200 and movable grip slipper are arranged at the fixation On seat 100, the end grip slipper is used for the end of fixed main shaft 500, and the conflict block 200 is for contradicting in main shaft 500 Eccentric body shaft 510 lower end, the activity grip slipper is used to contradict the upper end of eccentric body shaft 510 on main shaft 500.

Furthermore, it is understood that the structure of main shaft 500 is that main shaft 500 is different from tradition, this main shaft 500 has multiple and different axis Eccentric body shaft 510, it is preferred that with 2 or more eccentric body shafts 510 on the main shaft 500, these axis bodies are needed with card Ruler measures, but this measurement method is not only slow, but also is easy to appear mistake, leads to duplicate measurements or measurement Precision is lower；Measuring principle new at present is that main shaft 500 is fixed on this fixture first, and then measuring unit measures sampling Unit, the height of the calibrated altitude and eccentric body shaft 510 to be measured is then compared, obtain difference again, which is exactly The position of eccentric body shaft 510 on main shaft 500 and the error of size, cleverly by the eccentric body shaft 510 on main shaft 500 Size conversion is at the height value between eccentric body shaft 510 and bottom plate, consequently facilitating sampling and measuring, and can reliably clamp master Axis 500 is the key that in measurement method.

Preferably, this fixture can clamp entire main shaft 500, and make the eccentric body shaft 510 on each main shaft 500 Height all in fixed value, structurally, end grip slipper can clamp the columned both ends of main shaft 500, and When one of eccentric body shaft 510 is fixed by conflict block 200 and movable grip slipper, entire main shaft 500 is just by thoroughly solid It lives calmly, so as to easily efficiently be measured to each eccentric body shaft 510, also, this method of clamping, it can make every The height of a eccentric body shaft 510 and bottom plate is fixed, once there are the size exception or malposition of some eccentric body shaft 510, just It can feed back in the measurement difference of measuring unit, thus the problem of detecting main shaft 500 rapidly.

As shown in Figure 1 and Figure 2, on the basis of the above embodiment, there are two end-fixtures for the end grip slipper setting 310, and holding tank 320 is offered in the end-fixture 310, the end of main shaft 500 is arranged in the holding tank 320.

Preferably, end grip slipper is mainly used to clamp the column axis body portion at 500 both ends of main shaft, is V by opening The holding tank 320 of shape or rectangle is positioned, to reliably fix the both ends of main shaft 500, when 500 both ends quilt of main shaft It, can be by way of rotating main shaft 500 when holding tank 320 is fixed, then eccentric body shaft 510 is positioned.

As shown in Figure 1 and Figure 2, on the basis of the above embodiment, the fixing seat 100 offers the mounting groove of strip 110, conflict block 200 and two end-fixtures 310 are arranged in the mounting groove 110, two end-fixtures 310 In the both ends of the mounting groove 110, the conflict block 200 is located between two end-fixtures 310.

Preferably, 110 structure of mounting groove of strip, can play the role of mounting end fixture 310, end-fixture 310 Width and mounting groove 110 equivalent width, can make two end-fixtures 310 avoid end-fixture 310 be displaced sideways, and And two end-fixtures 310 are in a straight line；Conflict block 200 is located between two end-fixtures 310, can support Touch the lower part of some eccentric body shaft 510 on main shaft 500.

As shown in Figure 1 and Figure 2, on the basis of the above embodiment, limit is threaded in the end-fixture 310 Bolt 330, the caging bolt 330 are threaded through in holding tank 320, and the caging bolt 330 is for contradicting in main shaft 500 End.

The end of main shaft 500 can be withstood by caging bolt 330, so that the preliminary fixation of main shaft 500 is realized, in reality When fixed, it is only necessary to rotary spacing bolt 330, it can be final to contradict to main shaft 500 towards moving in holding tank 320 End.

As shown in Figure 1 and Figure 2, on the basis of the above embodiment, the movable grip slipper include adjust bolt 410 with And briquetting 420, be provided with strip-shaped hole 421 on the briquetting 420, the adjusting bolt 410 be threaded through in the strip-shaped hole 421 and It is threadedly coupled with the fixing seat 100, the briquetting 420 changes height by the adjusting bolt 410 to contradict in main shaft The upper end of 500 eccentric body shaft 510.

Preferably, adjusting bolt 410 can turn, thus contradict briquetting 420 in the upper end of eccentric body shaft 510, and item It is mobile that shape hole 421 can make 420 relative adjustment bolt 410 of briquetting, furthermore, it is understood that in actual use, first by briquetting 420 The mobile top that eccentric body shaft 510 is moved to along strip-shaped hole 421, then depresses briquetting 420 by adjusting bolt 410, so that Briquetting 420 contradicts on eccentric body shaft 510, since the upper and lower ends of briquetting 420 are pushed up by briquetting 420 and conflict block 200 respectively Firmly, so can be realized the positioning of each eccentric body shaft 510 on main shaft 500.

As shown in Figure 1 and Figure 2, on the basis of the above embodiment, the movable grip slipper further includes gag lever post 430, institute The limiting slot 120 that bar shaped is provided in fixing seat 100 is stated, the gag lever post 430 is threaded through on the briquetting 420, the limit The lower end of bar 430 is located in the limiting slot 120 and can slide along the limiting slot 120.

Preferably, gag lever post 430 can be moved along limiting slot 120, and strip-shaped hole 421 can make briquetting 420 is opposite to adjust It is mobile to save bolt 410, during practical adjustments, when briquetting 420 is mobile towards the eccentric body shaft 510 on main shaft 500, limit Bar 430 can play the role of guiding, so that briquetting 420 is merely able to move along the setting direction of limiting slot 120.

As shown in Figure 1 and Figure 2, on the basis of the above embodiment, it is equipped with reset spring in the adjusting bolt 410, The both ends of the reset spring contradict with the briquetting 420 and the fixing seat 100 connect respectively.

Preferably, reset spring can give briquetting 420 upward elastic force, when adjusting bolt 410 turns, be able to drive Briquetting 420 moves down, and when adjusting bolt 410 reversely turns, briquetting 420 is separated with eccentric body shaft 510, at this time adjustment spring top Briquetting 420 is played, so that briquetting 420 is located at the top for adjusting bolt 410.

The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute Belonging to those skilled in the art can make various modifications or additions to the described embodiments or using similar Mode substitute, but without departing from the spirit of the present application or beyond the scope of the appended claims.
