As shown in fig. 7, the back plate 104 of the enclosure 10 is directly fixed to the rail brackets 41, and the back plate 104 is fixedly connected to the mounting frame 4 of the shield carrier. The rear baffle 104 is mainly used for shielding and blocking the opening formed by the rear ends of the upper baffle 101, the left baffle 103 and the right baffle 102. As another embodiment, the rear baffle may also be directly and fixedly assembled with the upper baffle, the left baffle and the right baffle, that is, the rear baffle is fixedly connected to the baffle module.

As shown in fig. 7 and 9, a front baffle 18 is fixedly mounted at the front end of the anti-bending bearing plate 9, and the front baffle 18 is used as the above-mentioned blocking member for blocking the access opening reserved on the cover body 10 when the anti-bending bearing plate 9 moves to the testing position.

It should be noted that, in order to implement the bending test, corresponding avoiding openings are respectively provided on the cover body 10 and the bending bearing plate 9, so that the corresponding upper pressing head 12 and the corresponding lower pressing head can normally enter the test space to perform the bending test. As shown in fig. 7, avoidance openings are respectively formed at positions of the upper baffle 101, the left baffle 103 and the right baffle 102 corresponding to the upper indenter 12, so that the upper indenter 12 can normally enter the test space. Avoidance openings are respectively formed in the positions, corresponding to the two lower pressing plates 13 of the lower pressing head, of the anti-bending bearing plate 9, the left baffle plate 103 and the right baffle plate 102, so that the two lower pressing plates 13 can normally enter and exit the test space. The avoidance ports on the left baffle plate 103 and the right baffle plate 102, which are matched with the upper pressure head 12, are positioned at the upper ends of the baffle plates on the two sides, and the avoidance ports on the left baffle plate 103 and the right baffle plate 102, which are matched with the two lower pressure plates 13, are positioned at the lower ends of the baffle plates on the two sides.

In addition, as shown in the embodiment of fig. 7, in order to ensure that the upper pressure head 12 normally enters the test space, a corresponding avoiding structure is also arranged on the connecting plate 17 of the hoisting baffle module to avoid opening the upper pressure head 12.

In the embodiment shown in fig. 7, since the anti-bending bearing plate 9 is disposed on the guide rail support 41, and the lifting driving mechanism for driving the two lower pressing plates 13 to lift is disposed at the lower side of the support table 1, in order to ensure that the two lower pressing plates 13 can lift normally, a avoiding structure is also disposed on the guide rail support 41 at a position corresponding to the avoiding opening on the anti-bending bearing plate 9 for avoiding the two lower pressing plates 13. Therefore, when the bending test machine works specifically, the two lower pressing plates 13 are arranged below the guide rail support 41, when the bending bearing plate 9 moves to a test position, the test block 100 moves into a test space at the moment, the lifting driving mechanism drives the two lower pressing plates 13 to ascend, the two lower pressing plates 13 push the test block 100 upwards, the upper portion of the test block 100 is in jacking contact with the upper pressing head 12, and at the moment, the upper pressing head 12 is located between the two lower pressing plates 13, so that the upper pressing head 12 and the two lower pressing plates 13 form a three-point force application structure, and a normal bending test can be guaranteed. After the test is completed, the two lower pressing plates 13 sink to exit the test space and sink to the lower part of the anti-bending bearing plate 9 again, at this time, the test block 100 falls on the anti-bending bearing plate 9 again, and the anti-bending bearing plate 9 can bear the test block 100 and move to the pick-and-place position for the corresponding manipulator to take away the test block 100 after the test.

In addition, in the bending resistance testing machine, in order to improve the automation performance of the whole testing machine, a position sensor is provided on the rail mount 41 of the mounting frame 4. When the anti-bending bearing plate 9 carries the test block 100 to move to the test position of the anti-bending bearing plate 9, the anti-bending bearing plate 9 can trigger a corresponding position sensor, the position sensor sends corresponding detection information to a control unit of the anti-bending testing machine, and at the moment, a lifting driving mechanism on the anti-bending testing machine can drive the two lower pressing plates 13 to ascend so as to be matched with the upper pressing head 12 to perform an anti-bending test.

For the function of detecting that the anti-bending bearing plate 9 moves in place, which is performed by the position sensor, the position sensor can be a mechanical touch sensor, an electromagnetic induction sensor or a photoelectric trigger sensor. It is obvious to a person skilled in the art that the bending tester can be applied to any bending tester as long as it can be installed on the mounting frame 4 and normally detect that the bending bearing plate 9 is moved in place.

As another embodiment, the sweeping cylinder 71 may be supported and mounted on the mounting frame 4 by a support frame. In addition, as an embodiment, the pushing cleaning head may also adopt an electric push rod as a cleaning driving mechanism to drive the telescopic action.

When the pushing cleaning head 72 is driven to extend out, the cleaning cylinder 71 can push sundry debris with larger particles on the anti-bending bearing plate 9 away from the anti-bending bearing plate 9, so as to realize the purpose of cleaning. Moreover, since the pushing and cleaning head 72 is located above the anti-folding bearing plate 9, the pushing and cleaning head 72 has a lower side surface facing the anti-folding bearing plate 9, as shown in fig. 8, a dust suction port 720 is provided on the lower side surface of the pushing and cleaning head 72, a dust suction channel communicated with the dust suction port 720 is provided on the pushing and cleaning head 72, and the dust suction channel provides a negative pressure suction force to perform dust suction treatment through the dust suction port 720 when the pushing and cleaning head 72 cleans the sundries on the anti-folding bearing plate 9. Therefore, the pushing cleaning head 72 and the dust suction opening 720 are matched, so that the large and small sundry chips on the anti-bending bearing plate 9 can be cleaned, and the influence of the sundry chips on the precision of a subsequent anti-bending test can be avoided.

For the anti-folding bearing plate 9, because the anti-folding bearing plate 9 is provided with the avoiding opening for the two lower pressing plates 13 to pass through, when the pushing and cleaning head 72 extends and retracts back and forth to realize cleaning, part of sundry debris is easily pushed into the avoiding opening. To avoid accidents, for the lower supporting plate 14 of the guide rail support 41 for bearing the anti-folding bearing plate 9 moving to the pick-and-place position, as shown in fig. 7, a leakage hole 141 may be provided at a corresponding position of the lower supporting plate 14, and the leakage hole 141 is used to correspond to the avoidance opening of the anti-folding bearing plate 9 moving to the pick-and-place position, so that the sundries falling through the avoidance opening of the anti-folding bearing plate 9 can be discharged and will not be accumulated in the avoidance opening of the anti-folding bearing plate 9.

In addition, as shown in fig. 3 and 7, a cleaning striker plate 15 and a pushing cleaning head 72 are oppositely arranged at the left and right sides of the lower support plate 14, and an inclined guide plate 16 is provided at the lower side of the cleaning striker plate 15, and the inclined guide plate 16 is located at the lower side of the leakage hole 141 of the lower support plate 14 for carrying and guiding away the sundries falling from the leakage hole 141. When the device is used specifically, the recovery frame can be arranged below the inclined guide plate, so that the concentrated recovery treatment is convenient.

In fact, in the left and right spaced direction of the sweeping striker plate 15 and the pushing and cleaning head 72, the sweeping striker plate 15 and the lower support plate 14 are spaced to form a blanking gap for guiding the sundries pushed and cleaned by the pushing and cleaning head 72 to the inclined guide plate 16. In specific operation, when the pushing and cleaning head 72 is extended to push the larger-particle sundries on the anti-bending bearing plate 9 into the blanking gap, the larger-particle sundries fall onto the inclined guide plate 16 through the blanking gap, and finally the larger-particle sundries are guided and discharged by the inclined guide plate 16.

With the embodiment shown in fig. 7, the sweeping striker plate 15 may be arranged by overhanging the upper support plate by means of an upper support, and the inclined guide plate 16 is arranged by overhanging below the lower support plate 14 by means of a lower support.

According to the requirement of the bending test, the two lower pressing plates 13 can continuously push the test block 100 upwards until the test block 100 to be tested is broken, at the moment, the pressure data of the lower pressure sensor 11 is read and recorded, and whether the test block 100 is qualified or not can be judged accordingly. In practice, the test block 100 may be pressurized at a predetermined pressure, and if the test block 100 is not broken, it may be regarded as a pass, and if the test block 100 is broken or broken, it may be regarded as a fail. The specific test mode can be determined according to specific test requirements.
