Description

Technical Field

[0001] The invention belongs to the technical field of bolts, and in particular relates to a hardness detection device for bolt processing. Background Art

[0002] A bolt is a cylindrical, threaded mechanical part that fits into a nut. It consists of a head and a shank (a cylindrical body with external threads). It is used to fasten two parts with through-holes together with a nut. This type of connection is called a bolted joint. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection. The hardness testing device for bolt processing is a hardness testing device used to check the hardness of the bolt during bolt processing. It is widely used in bolt production and processing occasions, such as chemical plants and steel mills, and has good use effect. With the continuous development of society, people's demand for hardness testing devices for bolt processing is gradually increasing, but the existing hardness testing devices for bolt processing cannot meet people's needs, so a more convenient to use hardness testing device for bolt processing is needed; when the hardness testing device for bolt processing is used, the bolt cannot be stably fixed, resulting in the pressure head easily slipping when contacting the bolt, which brings inconvenience to the inspection of the bolt. At the same time, the height of the fixing platform cannot be adjusted, which is inconvenient for testing bolts of different lengths. When multiple bolts need to be tested for hardness, it is too troublesome to remove and replace them. In actual work, the hardness of the side of the bolt is rarely tested. Therefore, a hardness testing device for bolt processing is designed. Summary of the Invention

[0021] In a specific embodiment of the present invention, by providing two screw fixing seats 5 and two circular buckles 21, it is possible to greatly facilitate the detection of multiple bolts, thereby further improving work efficiency.

[0022] In this embodiment, after turning on the second electric push rod 6, the four circular support blocks 7 are pushed into the corresponding holes 14, so that the operating panel 4 can be fixed and the control operating panel 4 cannot be rotated. In addition, the outermost screw fixing seat 5 is aligned with the center of the diamond indenter 9, which can also support the operating panel 4.

[0023] In this embodiment, the screw fixing seat 5 is threadedly connected to the operating panel 4 so that the screw fixing seat 5 can be fixed to the surface of the operating panel 4. When it is necessary to inspect bolts of different sizes, the screw fixing seat 5 can be removed from the surface of the operating panel 4 and replaced with a screw fixing seat 5 of a bolt of the required size to continue working. Bolts of different sizes can be fixed.

[0024] In this embodiment, the circular housing 20 is threadedly connected to the operating panel 4 through its lower side, so that the circular housing 20 can be fixed to the surface of the operating panel 4. When it is necessary to inspect bolts of different sizes, the circular housing 20 can be removed from the surface of the operating panel 4 and replaced with a circular clip 21 of a bolt of the required size to continue working, so that bolts of different sizes can be fixed.

[0025] In this embodiment, by providing the threaded rod 24, the rotating handle 25, the supporting base 26, and the level 27, the device can be adjusted at any time according to the platform on which it is placed so as to be placed horizontally.

[0026] The working principle and use process of the present invention: After the present invention is installed, the threaded rod 24 is adjusted according to the actual situation of the platform on which the device is placed, and the support base 26 is moved up and down by rotating the rotary handle 25 until the level meter 27 is observed to be horizontal and stops rotating. After the bolts corresponding to the first screw inner hole 16 and the second screw inner hole 22 are threadedly connected and fixed with the screw fixing seat 5 and the circular buckle 21, the screw fixing seat 5 with the bolts and the circular card shell 20 are connected and fixed with the operating panel 4 through the threads on the lower side of the screw fixing seat 5 and the circular card shell 20. The angle of the bolt on the circular card shell 20 can be adjusted according to actual needs. After adjusting the angle required to measure the hardness, the first electric push rod 18 is turned on so that the arc-shaped card plate 19 clamps and fixes the circular buckle 21. By turning on the motor 11, the rotating shaft 12 is rotated, thereby driving the bevel gear 13 to rotate, and then the height of the bolt is adjusted. When the upper side of the bolt contacts the diamond indenter 9, the motor 11 is turned off, and then the second electric push rod 6 is turned on so that the second electric push rod 6 pushes the circular support block 7, and pushes the circular support block 7 into the hole 14 to fix the operating panel 4. Position, and the second electric push rod 6 and the circular support block 7 support the operating panel 4. When the circular support block 7 is pushed into the hole 14, the center of the outermost screw fixing seat 5 and the diamond indenter 9 will be aligned. The hardness of the bolt is tested by turning on the Rockwell hardness test. After the first bolt is tested, the operating panel 4 is moved downward a part, and the operating panel 4 is rotated to align the second bolt to be tested with the diamond indenter 9. Similarly, the circular support block 7 is inserted into the hole 14 for fixing, so as to maintain the center alignment of the outermost screw fixing seat 5 and the diamond indenter 9. The same method can be used to detect the remaining bolts. When different bolts need to be detected, the screw fixing seat 5 and the circular card shell 20 can be replaced, and the screw fixing seat 5 and the circular card shell 20 to be detected can be threadedly connected to the operation panel 4. The operation panel 4 can be controlled to the required height according to the height of the bolt to be detected. Through the above steps, bolts of different diameters and heights can be detected, which greatly increases the flexibility of the device, significantly improves the work efficiency and the smooth progress of the work. All electrical equipment in the device are powered by an external power supply.

[0027] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention.
