Specific implementation manners

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0030] As Figures 1-4 shown, the present invention provides a technical solution: a multifunctional test bench based on automatic control, including a test bench body 1. The test bench body 1 is a hollow test bench with an open top, and a transverse rod 2 is fixedly installed in the middle of the test bench body 1. Two test operation frames 3 are symmetrically and rotatably connected to the outside of the transverse rod 2;

[0031] The test operation frame 3 includes a bottom frame 31, a movable clamping seat 33, a clamping cylinder 35, a clamping plate 36 and a hinge seat 38. A through hole is provided in the middle of the bottom frame 31, and the transverse rod 2 passes through the through hole. Two mutually parallel sliding grooves 32 are opened on the bottom frame 31. Two limiting seats 34 are threadedly connected to the transverse plate of the movable clamping seat 33, and the limiting seats 34 are slidably connected in the corresponding sliding grooves 32. Four clamping cylinders 35 are equidistantly installed on the vertical plate of the movable clamping seat 33. The telescopic shaft of the clamping cylinder 35 passes through the vertical plate of the movable clamping seat 33, and a clamping plate 36 is fixed to the end of the telescopic shaft of the clamping cylinder 35. The movable clamping seats 33 of the two test operation frames 3 cooperate with each other to complete the clamping and fixing operation of the workpiece to be tested.

[0032] In order to improve the stability during the clamping process, anti-slip plates 37 are respectively pasted and fixed on the opposite sides of the two clamping plates 36, and grid-shaped anti-slip patterns are provided on the outer sides of the anti-slip plates 37.

[0033] On one side of the chassis 31, a hinge seat 38 is also fixed. A deflection adjustment cylinder 4 is rotatably connected inside the hinge seat 38, and the other end of the deflection adjustment cylinder 4 is rotatably connected to the inner bottom surface of the test bench body 1. The anti-deflection performance test operation of the test piece to be tested is completed through the deflection adjustment cylinder 4;

[0034] During specific use, first adjust the position of the limit seat 34 in the sliding groove 32. The screw of the limit seat 34 penetrates through the sliding groove 32, and a locking nut is threadedly connected to the bottom end of the screw of the limit seat 34. When adjusting, first loosen the locking nut. After adjusting the distance between the two clamping plates 36 to be between 30 - 50 mm from the clamping end of the test piece to be tested, use the locking nut to threadedly tighten and lock the limit seat 34, thereby completing the locking of the position of the movable clamping seat 33. Then use the clamping cylinder 35 to adjust the position of the clamping plate 36 so that the clamping plate 36 cooperates to complete the clamping and fixing operation of the test piece to be tested.

[0035] When the anti-deflection performance test is required, the distance between the test piece to be tested and the chassis 31 during clamping and fixing is not less than 50 mm. After clamping, use the deflection adjustment cylinder 4 connected to the side of the chassis 31 to expand or contract and adjust, driving the two chassis 31 to rotate in opposite directions on the cross bar 2 respectively, thereby driving the test piece to be tested to deflect. Furthermore, the anti-deflection performance test operation of the test piece to be tested can be completed through the expansion or contraction distance of the deflection adjustment cylinder 4.

[0036] A cross plate 13 is clamped near the top inside the test bench body 1, and a plurality of clamping holes 14 for adjusting the clamping position of the cross plate 13 are also opened on the test bench body 1.

[0037] A pressure test mechanism 6 is also installed on the cross plate 13. The pressure test mechanism 6 includes a downward pressure cylinder 61, a limit rod 62, and a lower pressure plate 63. The downward pressure cylinder 61 is vertically installed on the cross plate 13. The telescopic shaft of the downward pressure cylinder 61 extends to the bottom end of the cross plate 13, and a lower pressure plate 63 is fixed to the bottom end of the telescopic shaft of the downward pressure cylinder 61. Four corners of the top surface of the lower pressure plate 63 are respectively vertically fixed with limit rods 62, and the limit rods 62 are slidably connected to the cross plate 13.

[0038] A test plate 7 is clamped to the bottom end of the lower pressure plate 63. When the downward pressure cylinder 61 drives the lower pressure plate 63 to press down, the test plate 7 is driven by the lower pressure plate 63 to complete the pressure test operation of the test piece to be tested.

[0039] The test plate 7 is any one of a flat test plate, a circular test plate, and a conical test plate.

[0040] The chassis 31 is a trapezoidal plate, and mounting holes 39 are provided near the outer ends of the adjacent ends of the two chassis 31. A stabilizing plate 5 is mounted on the two mounting holes 39. When performing the pressure test operation on the test piece to be tested, the chassis 31 needs to be adjusted to a horizontal state, and at the same time, the stabilizing plate 5 is installed between the two chassis 31 to improve the stability between the chassis 31.

[0041] The stabilizing plate 5 is a rectangular plate, and two mounting rods 51 are symmetrically fixed on the center line of the bottom surface of the stabilizing plate 5. The mounting rods 51 are snap-fitted into the corresponding mounting holes 39.

[0042] During the test, the lower pressing cylinder 61 is used to drive the lower pressing plate 63 to press down. The lower pressing plate 63 drives the test plate 7 to press down on the test piece to be tested to complete the pressure test operation.

[0043] In order to facilitate the pressure test under different working conditions, the test plate 7 is a flat test plate, a circular test plate, and a conical test plate, so as to cooperate to complete the downward pressure test operations on the flat surface, circular surface, and conical surface.

[0044] In order to facilitate the waterproof performance test, a liquid inlet 11 is further provided near the top end inside the test bench body 1, and a drain pipe 12 is provided at the bottom end of the test bench body 1. During the test, the external test liquid is sent into the hollow cavity of the test bench body 1 through the liquid inlet 11, and the liquid level of the test liquid submerges the test piece to be tested. The waterproof performance test of the test piece to be tested is completed according to the immersion time.

[0045] A test signal display area 8 is further provided near the top end on the side of the test bench body 1. A plurality of signal lights 81 are provided in the test signal display area 8. In the above-mentioned anti-deflection performance test operation, pressure test operation, and waterproof performance test of the test piece to be tested, the connecting wires of the signal lights 81 are electrically connected to different positions of the test piece to be tested, so as to judge the state of the test piece to be tested according to the signals of the signal lights 81, and facilitate the efficient completion of the test operation process.
