Description

Technical Field

[0001] This utility model relates to the field of automotive parts, specifically to an intelligent inspection tool for axial clearance of drive shafts. Background Technology

[0002] The driveshaft assembly consists of an inner ball cage, an outer ball cage, and an intermediate shaft. The outer ball cage comprises a bell-shaped housing, a star-shaped sleeve, steel balls, and a cage. This axial clearance gauge is suitable for measuring the axial clearance between the outer ball cage and the intermediate shaft, as well as the axial clearance between the three ball pins and the intermediate shaft. The components of a driveshaft assembly are closely interconnected, so the axial clearance of the assembly has a significant impact on the product. If the clearance is not up to standard, it may cause jamming in various parts, resulting in abnormal noises during product operation and thus failing to meet the standards.

[0003] The force applied by the power source of the previous axial clearance gauge could not be measured and was not convenient to use. It required manual adjustment of the dial indicator, which was laborious and unreliable. In addition, the observation of the dial indicator pointer was subject to observation errors caused by human observation. Utility Model Content

[0024] The present invention will be further described below with reference to the accompanying drawings. An intelligent inspection tool for axial clearance of a transmission shaft includes a base plate 1 and a three-jaw chuck 2 mounted on the base plate (specifically, a support plate can be set on the base plate, and then the three-jaw chuck is mounted on the support plate) for fixing one end of the transmission shaft 9; a linear actuator 3 mounted on the base plate; a slide 31 connected to the linear actuator, moving back and forth in the horizontal direction and used to fix the transmission shaft; a displacement sensor 4 for measuring the moving distance of the slide; and a pressure sensor 5 for measuring the force output by the linear actuator.

[0025] The displacement sensor can be installed on the push rod or the sliding seat to sense the movement distance. The pressure sensor can be installed between the driving rod of the linear driver and the connecting rod. When testing is required, an output force is generally set, under which the moving distance of the push rod being less than the preset value is regarded as a qualified product. For example, when an output force of 100N is applied, a displacement less than a 0.06mm gap is a qualified product. The linear driver can be a hydraulic cylinder or a pneumatic cylinder. First, mount the three-jaw chuck on the half shaft at one end of the assembly, and then fixedly connect the sliding seat to the intermediate shaft of the transmission shaft. A first sliding rail 30 is provided on the base, and the sliding seat is slidably mounted on the first sliding rail.

[0026] In this embodiment, as shown in the figure, a display screen 6 is further included, and the display screen is used to display data obtained by the displacement sensor and the pressure sensor. A circuit board can be provided, the circuit board is connected to the displacement sensor and the pressure sensor, and the display screen is connected to the circuit board.

[0027] In this embodiment, as shown in the figure, a connecting rod 32 is further included, one end of the connecting rod is connected to the linear driver, and the other end is detachably connected to the sliding seat.

[0028] In this embodiment, as shown in the figure, the sliding seat is provided with a mounting groove 33 and a pressing seat 34, the pressing seat is arranged in the mounting groove, part of the connecting rod extends into the mounting groove and is arranged opposite to the pressing seat, a threaded rod 35 is threadedly connected to the pressing seat, and part of the threaded rod extends out of the sliding seat to drive the pressing seat to move forward or backward when rotating. When the threaded rod rotates, since the pressing seat cannot rotate (the space in the mounting groove is insufficient), it will move back and forth when the threaded rod rotates, and contact the connecting rod to achieve pressing when moving forward. This is for adjusting the position of the sliding seat to facilitate adapting to assemblies of different lengths.

[0029] In this embodiment, as shown in the figure, an operation groove 351 is provided on the threaded rod extending out of the sliding seat. A through groove is provided on the sliding seat for the threaded rod to extend out, and the operation part can be a hexagonal groove, which is convenient for a tool to drive the rotation.

[0030] In this embodiment, as shown in the figure, the sliding seat is provided with a second sliding rail 36 and a fixed seat 37, a sliding seat 38 is provided on the second sliding rail, and a clamping groove 381 for clamping the intermediate shaft is formed between the sliding seat 38 and the fixed seat. The sliding seat moves forward or backward to clamp the assembly or separate from the assembly.

[0031] In this embodiment, as shown in the figure, a rotatably connected operating rod 371 is provided on the fixed seat, the clamping groove is a threaded hole, and part of the operating rod is arranged in the threaded hole and is threadedly connected with the threaded hole. Rotating the operating rod drives the sliding seat to move back and forth, which is convenient for operation. Meanwhile, a handle for manual operation is provided on the operating rod to facilitate operation.

[0032] In this embodiment, as shown in the figure, the clamping groove is a polygonal groove. It can be rectangular, so that V-shaped grooves can be provided on both the fixed seat and the sliding seat.
