A spacing is set between the two pulleys 7 for sleeved with the belt 9, and a DBC bracket 14 is placed on the belt 9. A DBC is inserted and placed in the DBC bracket 14. There are two DBCs in the figure, namely a first DBC 20 and a second DBC 21. The DBC bracket 14 moves with the belt 9, thereby driving the DBC to move. The first bracket limit block 13 and the second bracket limit block 16 are respectively installed on the side of the belt located on the box body 5.

[0025] After the DBC recovery is completed, the first blocking cylinder 10 and the second blocking cylinder 11 retract, and after all the DBC brackets pass through the first blocking cylinder 10 and the second blocking cylinder 11, the first blocking cylinder 10 and the second blocking cylinder 11 extend, and the belt 9 starts to transport the DBC bracket 14 to the recovery location. Specific embodiments

[0026] The auxiliary device for automatically clamping and recovering DBC designed by the utility model is as follows Figure 1 As shown, it is fixed on the mobile platform 3 and moves forward, backward, left and right with the mobile platform 3 on the horizontal plane. The push-pull machine frame 1 is placed on a horizontal table and fixed, the mobile platform 3 can move horizontally relative to the push-pull machine frame 1, and the push-pull machine cutter head 2 can move vertically. The protective cover 4 is used to protect the internal mechanism of the auxiliary device for automatic clamping and recovery of DBC, and to prevent the operator from being injured when the mechanism is running.

[0027] like Figure 2 As shown, the first DBC 20 and the second DBC 21 can be inserted into the DBC bracket 14 and placed on the belt conveyor device composed of the belt bracket 8, the pulley 7, and the belt 9, so as to realize transmission from left to right.

[0028] like Figure 2 , 3As shown, the first blocking cylinder 10 and the second blocking cylinder 11 are generally in an extended state until the DBC bracket 14 is blocked by the first blocking cylinder 10 and the second blocking cylinder 11, at which time the belt 9 stops rotating. Then the first lifting cylinder 18 and the second lifting cylinder 19 extend out to push the first DBC 20 and the second DBC 21 upward until they reach the first bracket limit stop 13 and the second bracket limit stop 16, at which time the first DBC 20 and the second DBC 21 are completely fixed in the vertical direction.

[0029] After the first DBC20 and the second DBC21 are completely fixed in the vertical direction, the crank rocker device drives the arc pressure rod 15 to press the first DBC20 and the second DBC21 in the horizontal direction. Since the first blocking cylinder 10 and the second blocking cylinder 11 have fixed one direction of the horizontal plane at this time, coupled with the fixation of the arc pressure rod 15, the first DBC20 and the second DBC21 are completely fixed in the horizontal direction at this time. After being completely fixed, it is convenient for testers to perform shear force and tension tests.

[0030] After the test is completed, the first lifting cylinder 18, the second lifting cylinder 19 and the arc pressure rod 15 retract, and the first horizontal pushing cylinder 12 and the second horizontal pushing cylinder 17 extend to push the first DBC 20 and the second DBC 21 out of the DBC bracket 14. Then the first horizontal pushing cylinder 12 and the second horizontal pushing cylinder 17 retract, and the first DBC 20 and the second DBC 21 enter the DBC collection tray 6. The DBC tray 6 has a handle that can be pulled out to clean up the used DBCs. After the DBC recovery is completed, the first blocking cylinder 10 and the blocking cylinder 2 11 retract, and after all the DBC brackets have passed the first blocking cylinder 10 and the second blocking cylinder 11, the first blocking cylinder 10 and the second blocking cylinder 11 extend, and the belt 9 starts to transport the DBC bracket 14 to the recovery location.
