Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a protective device for a lifting vertical spindle rotation testing machine. Background Technology

[0002] Lifting-type vertical spindle rotary testing machines are widely used in many fields such as mechanical performance testing and materials research. These machines, through the high-speed rotation of the vertical spindle, can simulate various working conditions and perform performance testing on various specimens, playing a crucial role in industrial production and scientific research innovation.

[0003] During the operation of the testing machine, due to the high-speed rotation of the spindle, if the specimen is not securely fixed or malfunctions, it is very easy for specimen fragments to fly at high speed. The high-speed flying fragments have extremely strong kinetic energy, which can pose a serious threat to the personal safety of the operators. Therefore, we propose a lifting-type vertical spindle rotation testing machine protective device to solve the above problems. Utility Model Content

[0004] The main purpose of this invention is to provide a protective device for a lifting vertical spindle rotation testing machine, which can effectively solve the above problems.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0022] Specifically, in order to prevent flying debris from injuring workers, see [reference needed]. Figure 2 and Figure 3 In this embodiment, the protective component 2 includes a fixing frame 21. The bottom of the fixing frame 21 is fixedly connected to the top of the fixing plate 1. The fixing frame 21 has grooves on its left and right sides, and linear guide rails 22 are fixedly connected to the inner walls of the two grooves.

[0023] Further reading Figure 2 and Figure 3 In this embodiment, linear sliders 221 are slidably connected to the inner walls of the two linear guide rails 22, and acrylic protective covers 23 are fixedly connected to the ends of the two linear sliders 221 that are far apart from each other.

[0024] Further reading Figure 3 In this embodiment, the inner wall of the acrylic protective cover 23 is slidably connected to the outer surface of the fixing frame 21, and an operating handle 231 is fixedly connected to the front of the acrylic protective cover 23.

[0025] During implementation, when the device is in use, first remove the two anti-fall pins 3 to release the restriction on the acrylic protective cover 23. By pulling down the operating handle 231, the acrylic protective cover 23 can be moved downward. When the acrylic protective cover 23 moves downward, it will drive the two linear sliders 221 to move downward in the inner wall of the corresponding linear guide rail 22. When the acrylic protective cover 23 moves downward to a certain position, its bottom can contact the top of the fixing plate 1, which can fully cover the experimental area. When the specimen fails due to insecure fixing, the specimen fragments will fly at high speed. The flying fragments will be blocked by the acrylic protective cover 23 in the experimental area to avoid affecting the personal safety of the personnel outside.

[0026] Example 2: This example is based on Example 1 and includes an anti-fall pin.

The outer surfaces of the four rods are inserted into the inner walls of the insertion holes and positioning holes on the same side.

[0029] During implementation, after the device is used, pushing the operating handle 231 upward will move the acrylic protective cover 23 upward. When the acrylic protective cover 23 moves upward, it will drive the two linear sliders 221 to move upward in the inner wall of the linear guide rail 22. After the acrylic protective cover 23 moves upward a certain distance, the four insertion holes on its surface can correspond to the four positioning holes on the outer surface of the fixing frame 21. Inserting the two anti-fall pins 3 into the inner walls of the corresponding two insertion holes and positioning holes can quickly and conveniently fix the acrylic protective cover 23. The operation is simple, the structure is stable, and the practicality of the device is improved.

[0030] The working principle of this utility model is as follows: When the device is in use, first remove the two anti-fall pins 3 to release the restriction on the acrylic protective cover 23. By pulling down the operating handle 231, the acrylic protective cover 23 can be moved downward. When the acrylic protective cover 23 moves downward, it will drive the two linear sliders 221 to move downward in the inner wall of the corresponding linear guide rail 22. When the acrylic protective cover 23 moves downward to a certain position, its bottom can contact the top of the fixing plate 1, which can fully cover the experimental area. When the specimen fails due to insecure fixing, the specimen fragments will fly at high speed. The flying fragments will be blocked by the acrylic protective cover 23 in the experimental area to avoid affecting the personal safety of the personnel outside.

[0031] After the device is used, pushing the operating handle 231 upward will move the acrylic protective cover 23 upward. When the acrylic protective cover 23 moves upward, it will drive the two linear sliders 221 to move upward in the inner wall of the linear guide rail 22. After the acrylic protective cover 23 moves upward a certain distance, the four holes on its surface can correspond to the four positioning holes on the outer surface of the fixing frame 21. Inserting the two anti-fall pins 3 into the inner walls of the corresponding two holes and positioning holes can quickly and easily fix the acrylic protective cover 23. The operation is simple, the structure is stable, and the practicality of the device is improved.
