Abstract
The invention belongs to test technique of a material performance test, and particularly relates to a support position regulator used for a bending test. In the prior art, an operator usually adjusts a spacing between two supports through directly measuring distance of the supports with a vernier caliper, and whether distances, measured through the vernier caliper, between two ends of each support to a loading pressure head are equal is used for judging whether the loading pressure head is located at the center of the supports and is parallel to the supports. Such manner is not convenient to adjust the support position. The purpose of the invention is to provide the support position regulator used for a standard bending test. The spacing between the two supports is ensured to meet requirements of test standards, and the loading pressure head is ensured to be at the center of the supports and is parallel to the supports.
Description
Technical field
The invention belongs to the experimental technique of material properties test, it is specifically related to a kind of support position actuator for bend test, the position of bend test bearing can be adjusted, to ensure that loading span meets the requirement to bend test span of the standards such as ASTM, ISO, GB, it is ensured that the axis loading pressure head is positioned in the middle of bearing and parallels with bearing.
Background technology
When carrying out the mechanical property bend test such as composite, metal according to standards such as ASTM, ISO, GB, span between two bearings there is strict demand, require that two bearings are necessary equal to loading pressure head distance simultaneously, and parallel with loading pressure head, avoid bringing addition bend or shearing to test specimen, cause testpieces premature degradation, or produce irrational failure mode, affect the accuracy of result of the test.At present, operator generally adopt the mode that slide gauge directly measures bearing distance to adjust the span between two bearings, use two terminations of each bearing of vernier caliper measurement to judge to load whether pressure head is positioned at two bearing middles and parallel with bearing to whether the distance loading pressure head is equal.The regulative mode of this support position is very inconvenient, when particularly carrying out high temperature/low temperature bend test in environmental cabinet, owing to the space of environmental cabinet is narrow and small especially, two terminations of each bearing of vernier caliper measurement generally cannot be used to the distance loading pressure head, therefore it is difficult to ensure that load pressure head to be positioned at two bearing middles and parallel with bearing.
Summary of the invention
It is an object of the invention to provide a kind of support position actuator suitable in standard bend test, it is ensured that the span between two bearings meets the requirement of each test standard, it is ensured that load pressure head and be positioned at the middle of two bearings and parallel with bearing.
A kind of position control for standard bend test, it is characterized in that: include pressure head frame, short screw, long spiro nail, nut, pressure head, bearing, base and 1 adjustable plate, bearing can move on base, pressure head is fixed in pressure head frame, long spiro nail is by two nuts and the fastening of pressure head frame, and by 4 extra nut secured adjusted plates, short screw is threadeded with pressure head frame and is used for compressing pressure head；When carrying out position conciliation, adjustable plate is moved to measurement position on long spiro nail and is fixed by described 4 nuts of adjustable plate medial and lateral, and the bearing of homonymy is moved and is close on adjustable plate surface, and then fixing described bearing；Loosen described short screw afterwards, described pressure head frame is taken out and be reversibly mounted on described pressure head, the bearing of opposite side is moved and is close on adjustable plate surface, and then fix this collateral seat.
The present invention is used to adjust the position of bearing, it is ensured that the span requirement of test, it is ensured that two bearings are equal to the distance loading pressure head, and parallel with loading pressure head.
Compared with prior art, the invention have the advantages that
A () regulative mode is simple, use convenient, it is simple to operator regulate the span that test is required accurately；
B () ensures that loading pressure head is positioned at bearing naturally middle and parallel with bearing, it is not necessary to extra calibration operation；
C () is particularly suitable in the environmental cabinet of narrow space to regulate span, calibration support position, overcome the shortcoming that in conventional environmental cabinet, support position regulates inconvenience.

Detailed description of the invention
A kind of support position actuator for standard bend test, its structure is as it is shown in figure 1, include 1,2 short screws of 1 pressure head frame, 3,6 nuts 4 of 2,2 long spiro nails and 1 adjustable plate 5.2 long spiro nails 3 are complete thread screw, and after unclamping 4 nuts 4 of fastening adjustment plate 5, adjustable plate 5 can move freely on long spiro nail 3, and after tightening 4 nuts 4, adjustable plate 5 is completely fixed.Having 4 tapped through holes on pressure head frame 1,2 short screws 2 are connected with pressure head frame 1 by 2 screwed holes near centre position, and 2 long spiro nails 3 are connected with pressure head frame 1 by 2 screwed holes of both sides.After 2 long spiro nails 3 are screwed onto on pressure head frame, it is necessary to each use 1 nut 4 by locked for long spiro nail 3, it is prevented that the loosening and ensure that long screw thread is vertical with its mounting plane of long screw thread.
The specifically used method of support position actuator is as follows:
1) four nuts 4 of clamping adjustable plate are unclamped, adjust the position of two nuts 4 outside adjustable plate 5, as shown in Figure 2, make to be (L/2-h-R) to the distance inside pressure head frame 1 inside two nuts 4, make adjustable plate 5 medial plane and nut 4 fit tightly, use two other nut 4 to be fixed the position of adjustable plate 5.Using slide gauge to check, whether adjustable plate 5 lateral surface two ends are equal to the distance of the long spiro nail mounting plane of pressure head frame 1 and be (L/2-R), if there being deviation, use nut 4 slowly adjusts the position of adjustable plate to correct.
2) after adjusting the position of adjustable plate 5, as it is shown on figure 3, be inserted in loading pressure head 6 in the pressure head frame 1 of actuator, tighten two short screws 2, make a side of loading pressure head 6 and pressure head frame 1 fit tightly, and ensure that whole actuator does not loosen.The bearing 7 of movement governor side, makes bearing 7 inner side plane and adjustable plate 5 medial plane fit tightly, is fixed by bearing 7.So far, the position of a bearing 7 just has determined that.
3) bearing 7 position adjustments complete after, two nuts 4 inside two short screws 2 and adjustable plate 5 are unclamped (two nuts 4 outside adjustable plate can not unclamp), actuator are taken off from pressure head 6.Tighten inside adjustable plate 5 two nuts 4 to be retightened by adjustable plate 5.According to 2) regulate opposite side bearing 7 position.
