Description

A kind of two-way edge of a knife bearing centering and levelling test device

Technical field

The utility model relates to a kind of test unit, and particularly a kind of two-way edge of a knife bearing centering and levelling test device, this device are applicable to and utilize two-way edge of a knife bearing to carry out the centering and the leveling of pressure test.

Background technology

When utilizing two-way edge of a knife bearing to carry out the pressure test of the hinged test specimen in two ends, whether accurately test specimen centering is one of key factor that influences test findings.Traditional centering method is to knock edge of a knife bearing with iron hammer, and edge of a knife bearing is moved until reaching how much and physics centering.When utilizing this mode centering, be difficult to control quantitatively the displacement and the moving direction of edge of a knife bearing, reach accurate geometry in and physics centering, knock edge of a knife bearing with needing repeated multiple times, time is longer, often the centering time ratio official test time of bearing longer, centering efficient and test efficiency are very low.On the other hand, because the knife-edge part contact area is little, edge of a knife height of support is bigger, run-off the straight easily.The general method that cushion block is set that adopts realizes the level of edge of a knife bearing, owing to be subjected to the influence of cushion block height, does not have adjustable surplus, needs repeated multiple times to change the cushion block examination and transfers, and the leveling precision is low.In addition, test specimen end plate and edge of a knife bearing only are directly to stack, and without any fixation, when test specimen destroys, test specimen and edge of a knife bearing take place easily break away from, even the test specimen ejection is hurted sb.'s feelings.

Summary of the invention

Defective or deficiency at above-mentioned prior art existence, the purpose of this utility model is, a kind of centering, leveling of two-way edge of a knife bearing is provided and realizes edge of a knife bearing and the fixing test unit of test specimen end plate, when carrying out pressure test with this device, centering, leveling fast.

For realizing above-mentioned task, the utility model is achieved in that

A kind of two-way edge of a knife bearing centering and levelling test device, comprise the edge of a knife bearing that is arranged on the testing table, this edge of a knife bearing is made up of the last edge of a knife, the middle edge of a knife, the following edge of a knife and base plate, it is characterized in that, periphery at edge of a knife bearing is disposed with leveling frame and housing, described leveling frame one side links to each other with the base plate of edge of a knife bearing by the centering jackscrew, and leveling frame opposite side links to each other with housing by web joint, and described housing and testing table fuse; Be provided with adjusting screw at the last edge of a knife and the middle edge of a knife, wherein, the adjusting screw of the last edge of a knife contacts with the middle edge of a knife, and the adjusting screw of the middle edge of a knife contacts with the following edge of a knife, also is useful on the connecting screw rod that connects the test specimen end plate on the last edge of a knife.

Two-way edge of a knife bearing centering of the present utility model and levelling test device, processing and fabricating is simple, draws materials easily, and cost is low, can forever use.Can improve significantly two-way edge of a knife bearing in and leveling efficient, reduce the centering time, improve test accuracy and test speed, guarantee test findings accurately, reliable and experimental safe.

Embodiment

Referring to Fig. 1～Fig. 3, two-way edge of a knife bearing centering of the present utility model and levelling test device, comprise the edge of a knife bearing 1 that is arranged on the testing table 6, this edge of a knife bearing is made up of the last edge of a knife, the middle edge of a knife, the following edge of a knife and base plate, periphery at edge of a knife bearing 1 is disposed with leveling frame 3 and housing 2, described leveling frame 3 one sides link to each other with the base plate of edge of a knife bearing 1 by centering jackscrew 5, and leveling frame 3 opposite sides link to each other with housing 2 by web joint 4, and described housing 2 fuses with testing table 6; Be provided with adjusting screw 7 at the last edge of a knife and the middle edge of a knife, wherein, the adjusting screw 7 of the last edge of a knife contacts with the middle edge of a knife, and the adjusting screw 7 of the middle edge of a knife contacts with the following edge of a knife, also is useful on the connecting screw rod 8 that connects the test specimen end plate on the last edge of a knife.

Leveling frame 3 and two-way edge of a knife bearing 1 concentric setting.

Referring to Fig. 4, Fig. 5, there is the screw 9 that mates with adjusting screw 7 on connecting screw rod 8, four limits that two symmetries are set in the middle of the last edge of a knife.Adjusting screw 7 is installed the back and is contacted with the middle edge of a knife.

Referring to Fig. 6, Fig. 7,4 screws 9 that mate with adjusting screw 7 are set on the middle edge of a knife.Adjusting screw 7 is installed the back and is contacted with the following edge of a knife.

Referring to Fig. 8, Fig. 9, the base plate of the following edge of a knife and edge of a knife bearing 1 is welded to connect.

Two-way edge of a knife bearing centering of the present utility model and levelling test device, accurate when pressure test, as can to reach quick centering purpose.When centering, according to the initial installation site of test specimen, judge the offset direction of edge of a knife bearing 1, regulate the floor level motion of mobile edge of a knife bearing 1 then by centering jackscrew 5.Because of centering jackscrew 5 is threaded, and screw thread is continuous, spacing is very little, so can control the step pitch that moves horizontally of edge of a knife bearing 1 effectively, mobile continuously edge of a knife bearing 1.
