Several A guide grooves are provided on the outside of the support column 3. Several A guide strips 78 are connected to the inside of the lifting ring 73. The A guide strips 78 can slide in the A guide grooves and limit and guide the lifting ring 73, allowing the lifting ring 73 to move freely. The movement is more stable. A positioning part 74 is provided between the lifting plate 5 and the support column 3. The support column 3 is installed inside the outer shell 72, and the outer shell 72 is installed on the upper side of the B base plate 2. The lifting ring 73 is connected to the left and right sides with driving blocks 75. The driving blocks 75 are connected to the rear side of the lifting plate 5. A B guide groove is provided on the rear side of the driving block 75. A B guide strip 79 slides inside the B guide groove. The B guide strip 79 is connected to the inner side of the outer shell 72. The B guide strip 79 can position and guide the driving block 75, making the movement of the driving block 75 more stable. The moving block 75 has a threaded hole on its upper side, and a screw 76 is driven through the threaded hole via threaded engagement. The outer casing 72 has two rotating holes on its upper side.

The placement plate 4 is connected to the sliding end of the A-type electric linear slide rails 91. Drive bars 95 are connected to both the front and rear ends of the lower side of the drive plate 93. The two B-type electric linear slide rails 92 are respectively mounted on the front and rear sides of the A-type base plate 1.

Electric linear slide rail 91 A moves placement plate 4 back and forth on drive plate 93, and also moves left and right together with drive plate 93. At the same time, there are guide blocks and slide rails between placement plate 4, drive plate 93 and base plate 1 for guidance and positioning, making the movement of placement plate 4 and drive plate 93 more stable. The product is moved by placement plate 4 to adjust the position of the product on the horizontal plane, which facilitates the device to test the product at different positions and improves the testing efficiency of the device.

[0050] The impact block 6 is located on the upper side of the placement plate 4 and the lower side of the lifting plate 5. The impact unit 8 is located between the impact block 6 and the lifting plate 5. The impact unit 8 allows the impact block 6 to perform an impact resistance test on the product.

[0051] Impact unit 8 includes motor B 81 and lifting column 82. A limit ring 83 slides on the outer side of the lifting column 82, and a support block 84 is connected to the inner side of the limit ring 83. A connecting block 85 is provided on the lower side of the limit ring 83. Impact block 6 is installed on the lower side of the connecting block 85, which is connected to the lower side of the lifting column 82. A C-shaped support plate 86 is connected to the upper side of the support block 84, and the lifting column 82 is located inside the C-shaped support plate 86.

The inner side of the C-shaped support plate 86 is connected to a drive shaft 89. Positioning holes are provided on both sides of the C-shaped support plate 86, allowing the drive shaft 89 to rotate within these holes. A B mounting plate 810 is installed below the B motor 81, connecting it to the C-shaped support plate 86. The shaft end of the B motor 81 is connected to one end of the drive shaft 89. The magnetic attraction generating block 87 is connected to the winding reel 88 via a rope. An auxiliary block 811 is provided between the magnetic attraction generating block 87 and the winding reel 88, with an auxiliary hole on its upper side. The rope passes through the auxiliary hole, which positions the rope between the magnetic attraction generating block 87 and the winding reel 88, improving the operational stability of the impact unit 8. Motor B 81 and the magnetic attraction generating block 87 are connected to the power supply and controller via wires. Motor B 81 can rotate the winding reel 88 by driving shaft 89, causing the winding reel 88 to wind or lower the rope, thus moving the magnetic attraction generating block 87 up and down. The magnetic attraction generating block 87 uses magnetic force to move the lifting column 82 up and down together. The lifting column 82, through connecting block 85, carries the impact block... The three components move together. When the magnetic attraction block 87 releases the lifting column 82, the lifting column 82, connecting block 85, and impact block 6 fall under the action of gravity, realizing the impact resistance test on the product on the placement plate 4. At the same time, the mass of the impact block 6 can be changed to adjust the impact force of the device, which is convenient for subsequent testing. After the impact block 6 falls, it will not be lower than the limit ring 83 within the length of the lifting column 82 itself. Then the magnetic attraction block 87 descends to attract the lifting column 82, and then rises again to conduct the test, which improves the testing efficiency of the device.

[0052] Operating principle:

[0053] Place the product on the placement plate 4, and then adjust the position of the placement plate 4 on the horizontal plane through the adjustment unit 9, so that the placement plate 4 carries the product and adjusts its position. Then, adjust the height of the lifting plate 5 through the lifting unit 7, and test different impact forces with different impact blocks 6. Finally, use the impact unit 8 to make the impact block 6 perform a reciprocating test.
