[0018] The present utility model will be further described below in conjunction with the accompanying drawings.

[0019] According to Figures 1-4 As shown in the figure: The present utility model provides a detection tooling for the processing of a differential housing, which includes a base 1, and a bracket 3 is fixedly arranged on the base 1; a housing 6 is placed on the base 1, and the housing 6 includes a housing main body 18 and a flange 15. The housing main body 18 is fixedly connected to the flange 15, and connecting cylinders 17 are fixedly connected to both the housing main body 18 and the flange 15; mounting holes 16 are provided on the flange 15; two guiding grooves 7 are provided on the upper surface of the base 1, and positioning rods 8 inserted into the mounting holes 16 are slidably arranged in the guiding grooves 7; a sliding groove 10 is provided in the base 1, and a sliding structure fixedly connected to the positioning rod 8 is slidably arranged in the sliding groove 10; a groove 13 is provided in the base 1, and a detection device is arranged in the groove 13, and the detection device passes through the connecting cylinder 17 and is inserted into the housing main body 18; a hydraulic rod 4 is arranged in the bracket 3, and a pressing plate 5 pressing on the housing 6 is fixedly connected to the working end of the hydraulic rod 4.

[0020] By arranging two positioning rods 8 on the base 1 and using the mounting holes 16 inherent in the housing 6 itself, the housing 6 can be quickly positioned, the operation is convenient, and the detection device is arranged in the groove 13 of the base 1. While positioning the housing 6, the correspondence between the detection device and the housing 6 can also be completed, reducing the operation steps.

[0021] As Figure 3 、 4 shown, the detection device includes a detection head 14, and the detection head 14 is inserted into the housing 6; an ultrasonic generator 2 electrically connected to the detection head 14 is arranged on one side of the base 1. By adopting the technology of ultrasonic flaw detection, it is convenient to detect the quality inside the differential housing 6 that is not easy to observe with the naked eye.

[0022] As Figure 3 shown, the sliding structure includes a sliding block 11. The sliding block 11 is slidably arranged in the sliding groove 10, and the sliding block 11 passes through the guiding groove 7 and is fixedly connected to the positioning rod 8. A bidirectional screw rod 12 is rotatably arranged in the sliding groove 10. There are two sliding blocks 11, and the two sliding blocks 11 are respectively threadedly connected to the corresponding positions of the bidirectional screw rod 12; the sliding block 11 and the inner wall of the sliding groove 10 are corresponding squares, and the sliding block 11 and the inner wall of the sliding groove 10 are mutually attached, which can limit the rotation of the two sliding blocks 11, thereby converting the rotation of the bidirectional screw rod 12 into the movement of the sliding block 11, thereby driving the positioning rod 8 to slide, and is applicable to the housing 6 with mounting holes 16 of different spacings.

[0023] A pressure sensor 9 is arranged below the pressing plate 5, which can facilitate the staff to monitor and record the pressure generated by the hydraulic rod 4.

[0024] The principle of the present utility model

[0025] As Figure 4 shown, before detecting the differential case 6, the flange 15 is placed on the base 1, and the two positioning rods 8 are respectively inserted into the two mounting holes 16, thus quickly completing the positioning of the case 6; at the same time, when positioning the case 6, the detection head 14 passes through the connecting cylinder 17 and is inserted into the case body 18, completing the mating setting of the detection head 14 and the case 6. When performing quality inspection on the inside of the case 6, the ultrasonic generator 2 can be started, and using the detection head 14, ultrasonic flaw detection technology is used to detect the flaws inside the case 6.

[0026] At the same time, this application can also detect the state change of the differential case 6 when it is under pressure. Just start the hydraulic rod 4, so that the pressure plate 5 moves downward under the drive of the hydraulic rod 4 to exert pressure on the case 6, thus facilitating the quality inspection of the case 6 under the condition of applying pressure to the case 6 and improving the inspection effect; and the pressure sensor 9 can facilitate the staff to monitor and record the pressure generated by the hydraulic rod 4.

[0027] This application can also correspondingly adjust the distance between the two positioning rods 8 according to the different spacings of the mounting holes 16 on the case 6. As Figure 3 shown, by turning the bidirectional screw 12, driven by the sliding block 11, the two positioning rods 8 can move in the directions away from or towards each other until the distance between the two positioning rods 8 corresponds to the spacing of the mounting holes 16 on the case 6, thereby improving the practicability of this application.

[0028] The above has described the present utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and without departing from the creative purpose of the present utility model, without creative design, structures and embodiments similar to this technical solution are designed, they should all fall within the protection scope of the present utility model.
