Some pressure detection tools can detect a relatively single model of the supporting wheel assembly, and the production line must be stopped for detection, which affects production efficiency. In addition, the detection requires two people to perform it at the same time, and the detection result is unstable, time-consuming and labor-intensive, and there are safety hazards.

[0014] Beneficial Effects

[0015] The utility model provides a tool for detecting axial movement and pressure of a track roller assembly. Compared with the prior art, it has the following beneficial effects:

[0016] 1. In the utility model, the ball screw, pressure sensor, sensor probe, V-type pressure plate, magnetometer and other components are arranged. The function of the ball screw is to tighten the workpiece to the limit position, so as to make accurate readings and record the results. After the detection is completed, the ball screw is easily returned to a free state. The ball screw tightening device significantly reduces the labor force and greatly shortens the measurement time of the single-piece movement amount from the original 300 seconds to 85 seconds. In addition, the mobility of the tooling makes it possible to measure the movement amount of the supporting wheel finished product online and to check it at any time, and all this will not affect the assembly efficiency. In order to further optimize the detection process, a pressure sensor is added to monitor the pressure on the floating seal assembly to provide key data support for the trial production of new products.

[0017] 2. In the utility model, the roller assembly is placed on the detection plate by means of the detection plate, mounting frame, reset spring, trigger rod and push-type alarm. The detection plate slowly sinks by utilizing the gravity of the roller assembly, thereby cleverly avoiding direct hard contact between the roller assembly and the V-shaped support plate, and effectively protecting its surface from damage. As the detection plate descends, the trigger rod is driven down by the detection plate, and the push-type alarm is squeezed accordingly, sending out a signal, clearly prompting the operator that the roller assembly has been correctly placed in place and pressure testing can begin. This design not only ensures the protection of the equipment, but also improves the accuracy and reliability of the detection process. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] During operation, in order to ensure accurate measurement of the supporting roller assembly 11, the operator will select a suitable spacer block 8 according to its model and size to adjust the position of the V-shaped support plate 7 so that it is evenly supported on the rail surface of the supporting roller assembly 11. Then, the supporting roller assembly 11 is fixed with the V-shaped pressure plate 6, and the magnetic meter 9 is adsorbed to facilitate data reading. After the head of the magnetic meter 9 is calibrated to the "0" position, the operator starts the pressure sensor 3, and tightens the sensor probe 5 to the axial end face of the supporting roller assembly 11 through the ball screw 2 and the ball nut 4 mechanism, and records the reading.
