As in figure 2 it is shown, be the stress test mechanism according to a preferred embodiment of the present utility model.This stress test mechanism specifically includes that supporting construction, location structure, pressure measurement structure, and rotary connection structure.The structure of this device is described as follows:
In conjunction with shown in Fig. 2 and Fig. 3, described supporting construction includes: base 1, support column 2 and the gripper shoe 3 being assembled together from bottom to top, base 1 and gripper shoe 3 respectively rectangular platy structure, processing bolt via on base 1 and support column 2, gripper shoe 3 is processed thread, connect fixing with hexagon socket head cap screw 17, gripper shoe 3 is used for placing workpiece to be tested.
In the present embodiment, as an example and without limitation, workpiece to be tested is cast steel joint 100.According to the stress test mechanism that this utility model provides, actual it is not limited in the cast steel joint of structure shown in test Fig. 4, is further extended to the cast steel joint with other shapes or structure, even other products.As shown in Figure 4, the bottom surface 1001 of this cast steel joint 100 has a pair shrinkage pool 1001a, its end face 1003 has another to recess 1003a (shown in Figure 6), it addition, this cast steel joint 100 also has the groove 1002 of the end face substantially running through this cast steel joint 100 between this is to shrinkage pool 1001a and bottom surface.
Shown in Fig. 2, Fig. 4, Fig. 5, Fig. 6, described location structure is arranged in gripper shoe 3, and this location structure includes: support pin 4, locating piece 5 and position block 6 a pair.Wherein, support pin 4 to coordinate with the shrinkage pool 1001a bottom cast steel joint 100 respectively, for supporting this cast steel joint 100 and it being carried out Primary Location, locating piece 5 coordinates with the groove 1002 of cast steel joint 100, and position block 6 coordinates stop bit with the tail end of cast steel joint 100.
In conjunction with shown in Fig. 2 and Fig. 7, described pressure measurement structure includes: left and right test red needle 8,8 " and a pair fixing plate 9,9 of red needle ", wherein, left and right test red needle 8,8 " be fixed on by the first bolt 7 and nut 10 described to the fixing plate 9,9 of red needle " between, the fixing plate of described red needle 9 is (due to the fixing plate 9 of red needle; 9 " structure identical, therefore only select one and be described) preferably there is " convex " shape profile, the highest point of described " convex " shape profile has a upper surface a.
Shown in Fig. 2, Fig. 8, Fig. 9, described rotary connection structure includes: connect axle 11, connecting pin 12, board adapter sleeve 13, wherein, red needle fixes plate 9; 9 " connected with being connected axle 11 by connecting pin 12, connect axle 11 and be inserted from above into again described board adapter sleeve 13 and by the second bolt 18 fixing (with reference to Fig. 9), board adapter sleeve 13 is enclosed within board and connects on die shank 15 (with reference to Fig. 9), being fixed by the 3rd bolt 19, board connects die shank 15 and is connected with forcing press (not shown).
According to this rotary connection structure, red needle fixes plate 9,9 " can around described connecting pin 12 wallowing motion, the left and right test red needle 8,8 of corresponding drive " wallowing motion.Described connection axle 11 has a lower surface b, when the fixing plate 9 of described red needle keeps horizontal level, the upper surface a of the fixing plate 9 of described red needle opens with the lower surface b parallel interval being connected axle 11, when fixing plate 9 wallowing motion of described red needle is to maximum displacement place, described upper surface a is subject to the backstop of lower surface b and stops swinging.
According to the above-mentioned stress test mechanism that this utility model provides, its method of testing is as follows:
First, cast steel joint 100 is positioned in gripper shoe 3, support pin 4 to coordinate with a pair shrinkage pool 1001a of cast steel joint 100 bottom surface respectively, locating piece 5 coordinates with the groove 1002 of cast steel joint 100, position block 6 coordinates stop bit with the tail end of cast steel joint 100, thus being fixed in this stress test mechanism by cast steel joint 100.
Then, starting forcing press and start button, board adapter sleeve 13 drives red needle to fix plate 9,9 ', left and right test red needle 8,8 " move downwardly together; left and right test red needle 8; 8 " shrinkage pool 1003a on alignment cast steel joint 100 end face 1003, acts on the left and right test surfaces of cast steel joint 100 by force value, unclamps forcing press afterwards and starts button, left and right test red needle 8,8 ' along with the fixing plate 9,9 of red needle " move upward, away from cast steel joint 100.
If the force value on the left and right test surfaces of cast steel joint 100 is unbalanced, left and right test red needle 8; 8 " will along with the fixing plate 9 of red needle; 9 " around connecting pin 12 wallowing motion, now connect axle 11 to maintain static, when fixing plate 9 wallowing motion of red needle is to maximum displacement place, the upper surface a of the fixing plate 9 of this red needle is subject to connecting the backstop action of the lower surface b of axle 11, stop swinging, board adapter sleeve 13 continues to drive the fixing plate 9 of red needle; 9 " under press, left and right test red needle 8,8 " uniform force value is acted on the left and right test surfaces of cast steel joint 100.
After completing above-mentioned stress test, according to whether cast steel joint surface has the bad outward appearance such as pit, holes, deformation to judge whether to have inside cast steel joint the defects such as pore, shrinkage cavity, sand holes.Because if there being pore inside joint, after stress test, joint surface then there will be pit or holes.Therefore, after above-mentioned stress test, having the product of bad outward appearance directly to scrap, the product still good by stress test outward appearance is then judged to certified products.Carried out the stress test of cast steel joint by this set stress test mechanism, improve the quality stability of cast steel joint, it is ensured that the quality after cross bar welding, improve the safety coefficient of whole dish buckle frame system.
Should be appreciated that, according to the stress test mechanism that this utility model provides, actual being not limited in tests cast steel joint, is further extended to other products, and location structure therein suitably makes respective change.
According to the stress test mechanism that this utility model provides, use two stress test red needles that left surface and the right surface of product are tested simultaneously, change the method that single red needle is tested at twice, improve testing efficiency, further through rotary connection structure, the position of stress test red needle is adjusted automatically simultaneously, power the most balanced acts on product surface, it is ensured that the accuracy of test force value.
Above-described, it is only preferred embodiment of the present utility model, is not limited to scope of the present utility model, above-described embodiment of the present utility model can also make a variety of changes.Namely every claims according to this utility model application and description are made change simple, equivalent and modification, fall within the claims of this utility model patent.The not detailed description of this utility model be routine techniques content.
