Description

Technical Field

[0001] The utility model relates to the technical field of differential production, in particular to a differential detection device. Background Art

[0002] The differential is a vital component in a car's drivetrain that allows the left and right (or front and rear) wheels to rotate at different speeds to accommodate the difference in speed between the inside and outside wheels when the vehicle turns.

[0003] During differential production, precise measurement is crucial to ensuring product quality and performance. However, existing differential inspection devices are limited: their platforms only support a single inspection configuration. This means that each device can only be used to measure a specific differential parameter. This design limitation reduces inspection efficiency, as multiple different devices are required to comprehensively evaluate various differential performance indicators. Utility Model Content

[0004] Based on this, the purpose of the present invention is to provide a differential detection device to solve the problems of the above-mentioned background technology.

[0005] A differential detection device comprises: a working platform, a fixture assembly and a detection assembly arranged on the working platform;

[0006] The jig assembly includes a working plate arranged on the working platform, a plurality of working grooves arranged on the top of the working plate, and a jig for mounting a differential. The working plate is mounted on the working platform via a rotating structure so that a working cavity is formed between the working platform and the working plate. The working groove is communicated with the working cavity, and the jig corresponds to the working groove so that a detection assembly arranged in the working cavity can detect the differential through the working groove. The rotating structure is used to drive the differential on the jig to move toward or away from the detection assembly.

[0007] Compared with the prior art, the beneficial effects of the present application are as follows: the required detection components are installed in the appropriate position of the work platform. Next, the differential to be tested is placed on the jig, and it is ensured that it is correctly installed and fixed. Then, by driving the rotating structure, the working plate drives the jig and the differential to move toward the detection component. When the differential moves to the vicinity of the detection end of the detection component, the rotating structure will stop rotating. At this time, the detection component can start working, wherein some detection components can detect the differential from top to bottom, and another part of the detection components can also detect the differential from bottom to top through the working groove. Through this upper and lower bidirectional detection design, the differential detection device can significantly improve the detection efficiency. It not only reduces the time for repeated operations and equipment adjustments, but also allows multiple parameters of the differential to be detected within the same working cycle, ensuring the comprehensiveness and efficiency of the detection. The design of this device improves the flexibility and efficiency of detection and meets various differential detection needs.

[0008] Furthermore, a first mounting hole is provided at the bottom of the jig, and a plurality of second mounting holes are opened on the working plate. The jig is fixed to the working plate with a fixing member through the first mounting hole and the second mounting hole, and the plurality of second mounting holes are arranged around the working groove.

[0009] Furthermore, the jig includes a mounting plate, two support plates arranged on the mounting plate and a receiving groove opened on the support plate, an installation gap is provided between the two support plates, the receiving groove is adapted to the differential, and a through groove is opened on the mounting plate, and the through groove is adapted to the working groove.

[0010] Furthermore, a positioning plate is provided on a side of one of the two support plates or / and the other support plate away from the installation gap.

[0027] See also Figures 1 to 2 , shown is a differential detection device in an embodiment of the present utility model, comprising a working platform 10, a fixture 23 assembly 20 provided on the working platform 10, and a detection assembly 30;

[0028] Among them, the jig 23 assembly 20 includes a working plate 21 arranged on the working platform 10, and a plurality of working grooves 22 and a jig 23 for installing the differential 50 arranged on the top of the working plate 21. The working plate 21 is installed on the working platform 10 through a rotating structure 24 to form a working cavity 25 between the working platform 10 and the working plate 21. The working groove 22 is connected to the working cavity 25, and the jig 23 corresponds to the working groove 22, so that the detection component 30 arranged in the working cavity 25 can detect the differential 50 through the working groove 22. The rotating structure 24 is used to drive the differential 50 on the jig 23 to move toward or away from the detection component 30.

[0029] In this embodiment, the detection assembly 30 is mounted on the work platform 10 by fixing bolts. The driving rotation can be a motor.

[0030] In practical applications, the differential 50 detection device can flexibly install multiple detection components 30 on the work platform 10 according to the detection requirements. The operation process is as follows:

[0031] First, the required inspection assembly 30 is installed in the appropriate position on the work platform 10. Next, the differential 50 to be inspected is placed on the jig 23 and ensured to be properly installed and secured. Then, by driving the rotating structure 24, the working plate 21 drives the jig 23 and the differential 50 toward the inspection assembly 30. When the differential 50 moves near the inspection end of the inspection assembly 30, the rotating structure 24 stops. At this point, the inspection assembly 30 can begin operation, with some inspection assemblies 30 inspecting the differential 50 from top to bottom, while others inspect the differential 50 from bottom to top through the working slot 22. This bidirectional inspection design significantly improves inspection efficiency for the differential 50 inspection device. It not only reduces repetitive operations and equipment adjustments, but also allows multiple parameters of the differential 50 to be tested within the same operating cycle, ensuring comprehensive and efficient inspection. This design enhances inspection flexibility and efficiency, meeting various differential 50 inspection requirements.

[0032] See also Figures 3 and 4 Furthermore, to allow the fixture 23 to be replaced, a first mounting hole 231 is provided at the bottom of the fixture 23, and a plurality of second mounting holes 232 are provided on the working plate 21. The fixture 23 is fixed to the working plate 21 with fixing members through the first mounting holes 231 and the second mounting holes 232. The plurality of second mounting holes 232 are arranged around the working slot 22. The provision of multiple second mounting holes 232 allows different types of fixtures 23 to be placed in the working slot 22. The fixing members may be fixing bolts.

[0033] See also Figure 5 Specifically, the fixture 23 includes a mounting plate 233, two support plates 234 mounted on the mounting plate 233, and a receiving groove 235 formed on the support plates 234. A mounting spacer 236 is provided between the two support plates 234. The receiving groove 235 is adapted to fit the differential 50. A through groove 237 is provided on the mounting plate 233, and the through groove 237 is adapted to fit the working groove 22. This ensures smooth installation and testing of the differential 50.

[0034] More specifically, a positioning plate 238 is provided on one of the two support plates 234 or / and the other support plate 234 away from the installation space 236. In this embodiment, only one support plate 234 is provided with a positioning plate 238.

[0035] More specifically, the accommodating groove 235 includes a vertical groove 2351 and a limiting groove 2352 connected in sequence, and the size of the limiting groove 2352 decreases from top to bottom.

[0036] See also Figure 6 Furthermore, the detection assembly 30 includes an outer diameter detection structure 31, and the outer diameter detection structure 31 includes a support rod 311, a first lifting rod 312 connected to the support rod 311, and a first detection head 313 connected to the first lifting rod 312. The first lifting rod 312 moves up and down to drive the first detection head 313 to approach the differential 50. The outer diameter detection structure 31 may include a pneumatic calibrator, and the first detection head 313 is a sensor of the pneumatic calibrator. In an optional embodiment, a pneumatic calibrator may be installed in the working cavity 25, and the pneumatic calibrator in the working cavity 25 uses its sensor to detect the outer diameter of the differential 50 through the working slot 22, thereby achieving the effect of detecting the outer diameters of multiple positions of the differential 50 at the same time.

[0037] See also Figure 7 Furthermore, the detection assembly 30 includes an inner diameter detection structure 32, which includes a support frame 321, a second telescopic rod 322 mounted on the support frame 321, and a first sliding track 323. A first slider 324 is mounted on the first sliding track 323, and a second detection head 325 is mounted on the first slider 324. The second telescopic rod 322 drives the first slider 324 to move on the first sliding track, thereby driving the second detection head 325 to rise into the differential 50 for detection. If the inner diameter detection structure 32 includes a laser scanner, the second detection head 325 serves as the laser transmitting and receiving end of the laser scanner.

[0038] See also Figure 8 Furthermore, in order to facilitate the removal of the differential 50 after inspection, the inspection device also includes a blanking assembly 40, which includes a support column 41, a second sliding rail 42 arranged on the support column 41, a second slider 43 arranged on the second sliding rail 42, a second lifting rod 44 connected to the second slider 43, a mechanical claw 45 connected to the second lifting rod 44 and a driving chain 46 for driving the second slider 43.

[0039] In summary, the differential inspection device in the above-described embodiment of the present invention first installs the required inspection assembly 30 in an appropriate position on the work platform 10. Next, the differential 50 to be inspected is placed on the jig 23 and ensured to be properly installed and secured. Then, by driving the rotating structure 24, the working plate 21 drives the jig 23 and the differential 50 toward the inspection assembly 30. When the differential 50 moves near the inspection end of the inspection assembly 30, the rotating structure 24 stops rotating. At this point, the inspection assembly 30 can begin operation, with some inspection assemblies 30 inspecting the differential 50 from top to bottom, while other inspection assemblies 30 can inspect the differential 50 from bottom to top through the working slot 22. This bidirectional inspection design significantly improves inspection efficiency for the differential 50 inspection device. It not only reduces repetitive operations and equipment adjustment time, but also allows multiple parameters of the differential 50 to be inspected within the same operating cycle, ensuring comprehensive and efficient inspection. The design of this device improves the flexibility and efficiency of detection and meets various differential 50 detection requirements.
