[0021] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the following will describe the specific embodiments of the present utility model in detail with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0022] As shown in the figure, a tooling for detecting the ball base surface of a cylindrical roller 5 includes a base 1, a dial indicator 2, a dial gauge sleeve 3, a measuring frame 4, a V-groove 6, a measuring fulcrum 7, and a thrust assembly; the measuring frame 4 is arranged on the base 1; the base 1 is fixedly connected to the measuring frame 4; one end of the measuring frame 4 is sleeved with the dial gauge sleeve 3; the other end of the measuring frame 4 is provided with the measuring fulcrum 7; the measuring frame is fixedly connected to the measuring fulcrum; the tip of the dial indicator 2 passes through the dial gauge sleeve 3 and the measuring frame 4; one end of the V-groove 6 is fixedly connected to the base 1; the other end of the V-groove 6 is fixedly connected to the thrust assembly; the measuring fulcrum 7 is in contact with the ball base surface of the cylindrical roller 5; the tip of the dial indicator 2 is in contact with the ball base surface of the cylindrical roller 5; the cylindrical roller 5 is placed on the V-groove 6.

[0023] Furthermore, the thrust assembly includes a baffle 8, a top cap 9, a spring 10, and a connecting rod 12; the spring 10 is sleeved on the connecting rod 12; one end of the connecting rod 12 is connected to the top cap 9; the other end of the connecting rod 12 is connected to the baffle 8.

[0024] It should be noted that when the contact mode of the roller end face is surface-to-surface contact, if the two surfaces are not in a parallel state, one surface will be inclined after contact. If the top cap 9 is designed as a flat structure and is not in a parallel state with the roller end face, since the roller is in a free state, the position of the roller will change, affecting the test result. The head of the top cap 9 is designed as a circular arc, and the contact mode with the roller end face is point contact, avoiding the occurrence of this problem.

[0025] Even further, the thrust assembly can be applied to the ball base surface detection structure of cylindrical rollers in common general knowledge.

[0026] Furthermore, it also includes a nut 11; the other end of the connecting rod 12 passes through the baffle 8 and is connected to the nut 11.

[0027] Furthermore, the baffle 8 is "Z"-shaped; one end of the baffle 8 is fixedly connected to the V-groove 6; the other end of the baffle 8 is connected to the connecting rod 12.

[0028] It should be noted that the Z-shaped baffle is connected to the V-shaped groove. A hole is drilled in the middle of the baffle, and the connecting rod is placed into the hole. One side of the baffle is tightened with a nut, a spring is placed on the other side, and the top cap is tightened on the connecting rod. The top cap head contacts the center point of the end face of the roller. During detection, after pushing the top cap, the roller is placed on the V-shaped groove. After the hand is removed, the top cap presses against the roller through the elastic force of the spring, and the roller contacts the torsion spring gauge for reading.

[0029] Further, a through hole is provided in the middle of the other end of the baffle 8.

[0030] Further, the spherical surface of the top cap 9 contacts the spherical base surface of the cylindrical roller 5 on the side away from the measuring frame 4; a threaded hole is provided in the middle of the plane of the top cap 9.

[0031] Further, threads are provided at both ends of the connecting rod 12; the thread at one end of the connecting rod 12 is matched with the threaded hole of the top cap 9; the thread at the other end of the connecting rod 12 passes through the through hole of the baffle 8 and is matched with the nut 11.

[0032] It should be noted that if the roller is pushed by hand, if the contact position with the roller is far from the center point during the process, the roller is prone to tilt during the pushing process, affecting the detection result. The designed tooling top cap contacts the center of the roller end face to avoid tilting.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
