DETAILED DESCRIPTION

The utility model is further described below in conjunction with the accompanying drawings.

Embodiment: As shown in Figures 1 and 2, a transmission shaft yoke detection tooling includes a fixed platform 1 and a detection component 2. The fixed platform 1 is placed horizontally as a whole, and a placement plate 11 is provided at a limit position in the middle position of its upper surface. Both ends of the upper surface are provided with slide grooves 12 along its length direction. The placement plate 11 is placed horizontally, and a pressure sensor 13 is provided between its lower surface and the upper surface of the fixed platform 1; there are two detection components 2, which are symmetrically arranged at both ends of the upper surface of the fixed platform 1, and include a fixed vertical plate 21, a sliding plate 22 and a connecting block 23. A slider is fixedly arranged below the sliding plate 22, and is slidably connected to the slide groove 12 through the slider. A card slot 24 is vertically provided at the upper end of the inner side surface, and the inner side surface A support block 25 is fixedly provided at the lower end, and a rotating shaft 26 is vertically rotatably penetrated at the center of the support block 25. The connecting block 23 is located on the inner side of the sliding plate 22, and one end thereof is slidably connected to the slot 24 through a clamping block, and an ear hole detection column 27 cooperating with the yoke ear hole structure is coaxially fixedly provided at the other end. A threaded through hole 231 is vertically provided at the center of the connecting block 23, and an adjusting screw 28 is rotatably penetrated by a thread inside the threaded through hole 231. The lower end of the adjusting screw 28 is concentrically fixedly connected to the upper surface of the rotating shaft 26. The fixed vertical plate 21 is located on the outer side of the sliding plate 22, and is vertically fixedly connected to the upper surface of the fixed platform 1, and an electric push rod 29 is transversely fixedly provided between the fixed vertical plate 21 and the sliding plate 22.

The pressure sensor 13 is externally connected to a display component 14, and the display component 14 is fixedly arranged in the middle of the front end surface of the fixed platform 1. The display component 14 can be used to observe the detection value of the pressure sensor 13; the front end surface of the sliding plate 22 is vertically provided with a scale, and the front end surface of the connecting block 23 is provided with a conical calibration groove 232 in the middle position of one side close to the sliding plate 22. The cooperation between the calibration groove 232 and the scale can increase the accuracy of the vertical position adjustment of the ear hole detection column 27; the ear hole detection column 27 is arranged horizontally as a whole, and its end away from the connecting block 23 is a truncated cone structure. The ear hole detection column 27 with this structure can increase its smoothness when moving from the detection position to the inside of the yoke ear hole; the upper end of the adjusting screw 28 is concentrically fixedly provided with a square auxiliary rotating block 281, and the auxiliary rotating block 281 can increase the convenience of the rotation operation of the adjusting screw 28.

Before using the utility model, the height of the ear hole detection column 27 needs to be adjusted according to the vertical distance between the center of the ear hole and its bottom end in the design drawing of the yoke to be detected, so that the vertical distance between the center of the ear hole and its bottom end in the design drawing of the yoke to be detected is consistent with the vertical distance between the center of the ear hole detection column 27 and the upper surface of the placement plate 11. The specific adjustment operation is as follows: the vertical sliding connection between the connecting block 23 and the sliding plate 22, the rotation connection between the rotating shaft 26 and the supporting block 25, and the concentric fixed connection between the adjusting screw 28 and the rotating shaft 26 can be realized by rotating the adjusting screw 28. The threaded rotation connection between the threaded through hole 231 at the center of the connecting block 23 can drive the connecting block 23 to move vertically while the adjusting screw 28 rotates, and then drive the ear hole detection column 27 to adjust its position in the vertical direction through the vertical movement of the connecting block 23. The utility model adopts this structure, and the height of the ear hole detection column 27 can be adjusted according to the vertical distance between the center of the yoke ear hole and its bottom, so that it is suitable for the detection of transmission shaft yokes of different lengths, thereby increasing its applicability; at the same time, by setting a scale and a calibration groove 232, and utilizing the coordination of the calibration groove 232 and the scale, the accuracy of the vertical position adjustment of the ear hole detection column 27 can be increased.

After the height adjustment of the ear hole detection column 27 is completed, when the utility model is used, first, the yoke to be detected is placed horizontally above the placement plate 11. At this time, the pressure sensor 13 is used to detect the pressure applied downward by the yoke and the placement plate 11 due to their own gravity, and it is displayed in the display component 14. Then, the electric push rod 29 is controlled to be unfolded. At this time, the sliding connection between the slider below the sliding plate 22 and the slide groove 12 can be used to utilize the thrust effect on the sliding plate 22 when the electric push rod 29 is unfolded to drive the sliding plate 22 to adjust the lateral position, and then through the lateral movement of the sliding plate 22, the connecting block 23 and the ear hole detection column 27 are driven to move horizontally, so that the ear hole detection column 27 is moved from the standby position to the inside of the ear hole of the yoke to be detected, and its position change from the standby position to the detection position is realized. In this process, due to the ear hole 22 before use, the ear hole 22 is adjusted to the inner ear hole of the yoke to be detected. The height of the detection column 27 is adjusted so that the ear hole detection column 27 and the ear hole of the yoke to be detected are at the same height, and the structure of the ear hole detection column 27 is matched with the structure of the yoke ear hole. Therefore, in the process of the ear hole detection column 27 moving from the standby position to the detection position, if the value detected by the pressure sensor 13 does not change, it means that the contact between the yoke and the placement plate 11 does not change, which proves that the verticality of the ear hole is good and the yoke is a good product; if the value detected by the pressure sensor 13 changes, it means that in the process of the movement of the ear hole detection column 27, due to the squeezing between the inner wall of the yoke ear hole, the overall position and angle of the yoke are changed, which leads to the change of the contact between the yoke and the placement plate 11, which proves that the verticality of the ear hole does not meet the standard and the yoke is a defective product; in general, the utility model has the advantages of accurate and convenient detection operation and good applicability.

The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or replaced by equivalents, and any modification or equivalent replacement that does not depart from the spirit and scope of the utility model should be included in the scope of the claims of the utility model.
