Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of detection tools, in particular to a detection tool for a high-temperature bridge box shaft blank. Background Art
[0002] During the processing of the bridge box shaft, it needs to be processed into a blank by a forging machine. The structure of the blank is basically the same as that of the final product. Figure 1 and Figure 2 As shown, they all include a flange 2, an inner cavity 1 is provided on the inner side of one end of the flange 2, the other end of the flange 2 is a conical surface 22, and the side of the inner cavity 1 includes a first part 11, a second part 12 and a third part 13 from the bottom to the top. In the actual production process, the blank after forging needs to be subjected to processing accuracy inspection, including the processing accuracy of the inner cavity 1, the processing accuracy of the flange outer edge 21, and the relative processing accuracy of the inner cavity 1 and the flange outer edge 21.
[0003] In the prior art, since the temperature of the blank just after forging is very high (about 800 degrees Celsius) and the surface is a dazzling red color, it is necessary to wait until the blank is cooled to room temperature and then use a professional detection device (such as a three-coordinate measuring device used in the three-coordinate measurement method) to test the processing accuracy of the blank. The commonly used cooling method for the bridge box shaft blank is natural cooling. During the natural cooling process, the blank is placed horizontally.
[0004] The above detection method has the following technical problems: the processing accuracy detection is carried out after the blank has cooled to room temperature. When a blank that needs to be reforged is detected, the blank needs to be reheated from room temperature to a temperature that meets the forging requirements (above 1000 degrees Celsius), which consumes a lot of energy; the detection must be carried out after cooling to room temperature, which takes too long to wait and is inefficient; the processing accuracy requirements for the blank are not high, and the use of professional detection equipment takes a long time and is inefficient. Utility Model Content
[0005] The purpose of the utility model is to overcome the deficiencies of the prior art and to provide a detection tool specially used for detecting a high-temperature bridge box shaft blank.
[0006] In order to achieve the above-mentioned object, the utility model provides a detection tool for a high-temperature bridge box shaft blank, the detection tool comprising:
[0007] The main body is a plate-like structure, the middle part of the lower end surface of the main body can be fitted with the bottom of the inner cavity of the standard-sized bridge box shaft blank, the two side parts of the lower end surface of the main body can be fitted with the side of the inner cavity of the standard-sized bridge box shaft blank, the opposite ends of the lower end surface of the main body are respectively provided with corners, the two corners can be fitted with the opposite ends of the top of the inner cavity of the standard-sized bridge box shaft blank, the main body includes flange outer edge detection parts arranged on opposite sides, the inner sides of the two flange outer edge detection parts are respectively fitted with the radial opposite ends of the outer edge of the standard-sized flange;
[0008] A rectangular frame, the outer peripheral surface of the frame is fixedly connected to the upper end surface of the main body, and an opening is provided on one end of the frame away from the main body, and the opening is located in the middle part of the frame;
[0009] A control rod, one end of which is fixedly connected to the upper end surface of the main body, and the other end of which is relatively far away from the main body, and the control rod is arranged along the length direction of the main body.
[0010] Furthermore, the main body also includes: a first detection part, which is located in the middle position of the main body, and the lower end surface of the first detection part can be fitted with the bottom of the inner cavity of the standard-sized bridge box shaft blank; two second detection parts, which are respectively arranged on both sides of the first detection part, and the lower end surface of the second detection part can be fitted with the first part of the standard-sized bridge box shaft blank.
[0011] Furthermore, the main body also includes: two third detection parts, which are respectively arranged on the outside of the two second detection parts, and the lower end surface of the third detection part can be fitted with the second part of the standard size bridge box shaft blank.
[0012] Furthermore, a heat-insulating handle is provided at one end of the control rod away from the main body.

[0017] The beneficial effects of the utility model are:
[0018] During the cooling process of the forged blank, when the red color of the blank fades, place the bridge box shaft blank in a vertical direction with its inner cavity facing upwards, hold the joystick, and let the middle part of the main body cooperate with the bottom of the inner cavity of the bridge box shaft blank, the two side parts of the lower end face of the main body cooperate with the side of the inner cavity of the bridge box shaft blank, the two corners cooperate with the opposite two ends at the top of the inner cavity of the bridge box shaft blank, and the two flange outer edge detection parts cooperate with the radial opposite two ends of the flange outer edge respectively. By observing the gap between the lower end face of the main body and the various parts of the inner cavity, the inner cavity of the bridge box shaft blank can be quickly detected. By observing the gap between the outer edge detection parts of the flange, the outer edge of the flange can be quickly detected. By observing the gap between the main body and the bridge box shaft blank as a whole, the relative processing accuracy of the inner cavity and the outer edge of the flange can be quickly detected.

The utility model is moved by the operating rod to allow the inner side of the frame away from the end of the operating rod to contact the blank. The operating rod is then rotated to allow the side of the frame to contact the conical surface of the flange. The optical axis end of the bridge box shaft blank is used as a fulcrum, and the operating rod is lifted upward to achieve the vertical placement of the bridge box shaft blank.
