[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] See also Figure 1-Figure 5 The present invention provides a servo-type material testing machine, including a test box 1, a hydraulic servo cylinder 2 is fixedly installed on the top of the test box 1, the telescopic end of the hydraulic servo cylinder 2 penetrates the test box 1 and extends to the inner cavity of the test box 1 to be fixedly installed with an upper clamp 3, a conical support seat 5 is fixedly installed on the bottom of the inner cavity of the test box 1, a lower clamp 4 is fixedly installed on the top of the support seat 5, and a box door 6 is hinged on the front of the test box 1.

[0026] By using the hydraulic servo cylinder 2, the upper clamp 3 and the lower clamp 4 in coordination, after placing the two ends of the sample between the upper clamp 3 and the lower clamp 4, the sample can be squeezed by the hydraulic servo cylinder 2 to test its compressive strength or flexural strength.

[0027] As a preferred example, Figure 3 As shown, a discharge trough 27 is provided at the bottom of the inner cavity of the test box 1, and a support assembly for supporting the support seat 5 is fixedly installed in the inner cavity of the discharge trough 27. The support assembly includes a positioning plate 28 fixedly installed on the bottom of the support seat 5, and a positioning rod 29 is fixedly installed on the surface of the positioning plate 28. The end of the positioning rod 29 away from the positioning plate 28 is fixedly connected to the inner wall of the discharge trough 27.

[0028] By setting the discharge chute 27 , the oxide scale that falls off during the test will be discharged into the collection box 24 below through the discharge chute 27 . By setting the support assembly, the support seat 5 can be supported and fixed above the discharge chute 27 .

[0029] Among them, Figure 4As shown, the inner cavity of the test box 1 is installed with a cleaning component for cleaning the inside of the upper clamp 3 and the lower clamp 4, and the cleaning component includes a connecting plate 7 arranged on the back of the upper clamp 3 and the lower clamp 4, and two groups of support plates 8 are fixedly installed on the front of the connecting plate 7 and between the upper clamp 3 and the lower clamp 4, and cleaning brushes 9 are installed on the outer sides of the two groups of support plates 8. A driving component for driving the brush 9 to move is installed on the back of the connecting plate 7, and the driving component includes a driving motor 10 fixedly installed on one side of the test box 1, and the output shaft of the driving motor 10 passes through the test box 1 and extends to the inner cavity of the test box 1, where a driving screw 11 is fixedly installed, and a slide seat 12 is mounted on the surface of the driving screw rod 11, and one side of the slide seat 12 is fixedly connected to the back side of the connecting plate 7.

[0030] Through the setting of the cleaning component, when it is necessary to clean the residual oxide scale in the upper clamp 3 and the lower clamp 4, the output shaft of the driving motor 10 will drive the driving screw 11 to rotate, and then drive the connecting plate 7 and the support plate 8 to move through the slide 12, so as to drive the brush 9 to clean the oxide scale inside the upper clamp 3 and the lower clamp 4.

[0031] It is worth noting that if Figure 4 As shown, a guide assembly for improving the movement stability of the connecting plate 7 is also installed on the back of the connecting plate 7, and the guide assembly includes two sets of guide seats 13 fixedly installed on the back of the connecting plate 7, and the inner cavity of the guide seat 13 is slidably connected with a guide rod 14, and both ends of the guide rod 14 pass through the guide seat 13 and extend to the outside of the guide seat 13 and are fixedly connected to the inner wall of the test box 1.

[0032] By setting the guide assembly, the stability of the movement of the connecting plate 7 can be improved. When the connecting plate 7 moves, it will drive the guide seat 13 to slide on the surface of the guide rod 14.

[0034] When the box door 6 is opened, the movement of the box door 6 will drive the pressure plate 19 to move, so that the pressure plate 19 presses the roller 18. The movement of the roller 18 will drive the moving plate 16 to move through the connecting rod 17, so that the moving plate 16 approaches the contact sensor 15. When the contact sensor 15 senses that the moving plate 16 is approaching, it will send a working signal to the drive motor 10 to control the operation of the cleaning component.

[0035] Furthermore, if Figure 5 As shown, the connecting rod 17 is movably installed on one side of the test box 1 through an elastic connecting component. The elastic connecting component includes a fixing seat 20 fixedly installed on one side of the test box 1. A through hole 21 is opened on the surface of the fixing plate.

The tension spring 22 is fixedly connected to the surface of the movable plate 16 on the side away from the fixing plate.

[0036] Through the setting of the elastic connection component, when the pressure plate 19 presses the roller 18, the movement of the connecting rod 17 will drive the movable plate 16 to move to pull the tension spring 22. When the box door 6 is closed, the reaction force generated by the tension of the tension spring 22 will drive the movable plate 16 and the roller 18 to reset.
