A kind of screw rod correcting instrument of beating, comprise base (1), bracing frame (2) and dial test indicator (3) are installed on the base (1), support frame as described above (2) upper end is equipped with a straightening mechanism, the lower end is equipped with a detent mechanism that is used for fixing screw rod, straightening mechanism is made of rectification handle (5), rectification spring (10) and pressure head (9), and described rectification handle (5) is positioned at corrects spring (10) top, and pressure head (9) is connected with rectification spring (10); Detent mechanism by position fixing handle (6), retainer spring (7), rolling center (8) and fixedly tip (11) constitute, described rolling center (8) and fixedly be fixed with screw rod between the tip (11), described pressure head (9) be positioned at rolling center (8) and fixedly between the tip (11) screw rod directly over.
Wherein said dial test indicator (3) is provided with gauge head (4), this gauge head (4) be positioned at rolling center (8) and fixedly the screw rod between the tip (11) contact.
Wherein said rolling center (8) is connected with position fixing handle (6) by retainer spring (7), drives retainer spring (7) control rolling center (8) by position fixing handle (6) and moves forward and backward.
Wherein said rectification spring (10) is connected with pressure head (9), correct spring (10) by correct handle (5) time pressure-controlled pressure head (9) to be positioned at rolling center (8) and fixedly the screw rod between the tip (11) correct.
The utility model is fixed the screw rod of rectification to be detected by detent mechanism, and the gauge head on the dial test indicator is contacted with screw rod, rotating screw bolt, show jitter values by dial test indicator, control is corrected handle and is pressed down, and presses down and correct spring thereupon, and pressure head is extruded, withstand on the screw rod of rectification to be detected, it is corrected.Compared with prior art, the utility model is simple in structure, easy to operate, can detect synchronously it being corrected that rectification screw rod to be detected beats, and has avoided correcting not in place, or the problem of overcorrection has improved rectification efficient.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Identifier declaration among the figure: base 1, bracing frame 2, dial test indicator 3, gauge head 4, correct handle 5, position fixing handle 6, retainer spring 7, rolling center 8, pressure head 9, correct spring 10, fixing tip 11.
The specific embodiment
Core concept of the present utility model is: utilize rolling center and fixedly tip the screw rod of rectification to be detected is fixedly clamped, detect the jitter values of screw rod then by dial test indicator, and according to this jitter values, control is corrected handle and is pressed down, the rectification spring is pressed down thereupon, and with the pressure head extrusion, withstand on the screw rod of rectification to be detected, it is corrected.
For setting forth thought of the present utility model and purpose, the utility model is described further below in conjunction with the drawings and specific embodiments.
See also shown in Figure 1ly, Fig. 1 is a structural representation of the present utility model.The utility model provides a kind of screw rod correcting instrument of beating, and being mainly used in has the screw rod of locating hole to carry out glitch detection and rectification to two ends.
The wherein said screw rod correcting instrument of beating is made of base 1, the bracing frame 2, the dial test indicator 3 that are installed on the base 1, the upper end of support frame as described above 2 is equipped with a straightening mechanism, the lower end is equipped with a detent mechanism that is used for fixing screw rod, 3 of dial test indicators are installed in a side of bracing frame 2, and parallel with detent mechanism.
Straightening mechanism constitutes by correcting handle 5, rectification spring 10 and pressure head 9, described rectification handle 5 is positioned at the top of correcting spring 10, pressure head 9 is connected with rectification spring 10, when rectification handle 5 presses down, can will correct spring 10 compressions, and correct the elastic force that spring 10 is produced, then be given pressure head 9 by conduction, pressure head 9 produces downward pressure under this elastic force effect.
Detent mechanism by position fixing handle 6, retainer spring 7, rolling center 8 and fixedly tip 11 constitute, described rolling center 8 and fixedly be fixed with the screw rod of rectification to be detected between the tip 11, described pressure head 9 be positioned at rectification to be detected screw rod directly over, when pressure head 9 presses down, can correct the screw rod of rectification to be detected.
The screw rod two ends of rectification to be detected are provided with locating hole, and rolling center 8 and fixedly tip 11 can corresponding withstand in the locating hole at its two ends, be fixed, concrete grammar is: at first according to the length of the screw rod of rectification to be detected, regulate position fixing handle 6, retainer spring 7 is pulled out, the rolling center 8 that is positioned at retainer spring 7 front ends is also pulled out thereupon, this moment rolling center 8 and fixedly the distance between the tip 11 become big, the screw rod of rectification to be detected put into rolling center 8 and fixedly between the tip 11, unclamp position fixing handle 6, under retainer spring 7 effect, rolling center 8 and fixedly tip 11 screw rod of rectification to be detected can be clamped.
