fig. 2 is a schematic cross-sectional view of the mandrel and the insert according to an embodiment of the present invention.
Detailed Description
The embodiments of the present invention will be further explained with reference to the accompanying drawings: as shown in fig. 1-2, the device for detecting the needle roller releasing force and assisting in removing the needle roller comprises a base 1 and a mandrel 2 for fixing a retainer and the needle roller, wherein two mandrel fixing frames 3 for being respectively matched, connected and supported with two ends of the mandrel 2 are arranged on the base 1, at least one mandrel fixing frame 3 forms a sliding connection with the base 1, the mandrel fixing frame 3 can be connected with or separated from one end of the mandrel 2 based on the sliding motion relative to the base 1, the mandrel 2 comprises an outer circumferential wall 4 which is matched and movably sleeved with the retainer, and a groove 5 for accommodating the needle roller is arranged on the outer circumferential wall 4. The base 1 is provided with an elongated slot in cooperation with the mandrel fixing frames 3, the mandrel 2 is replaced and the mandrel 2 is installed by adjusting the positions of the mandrel fixing frames 3 on the two sides, and the mandrel 2 is provided with a groove 5 for detecting the withdrawal force of the roller pins and a reserved area after the roller pins are removed.
The extrusion part 13 is an arc-shaped clamp, and the operation surface of the extrusion part 13 contacted with the roller pins is matched with the roller pins.
The two sides of the top of the pressing rod 12 are connected with connecting rods 14, the connecting rods 14 are fixed on the first cross beam 8 through tension meters 15, the tension meters 15 are parallel to the pressing rod 12 in the vertical direction, and recesses for fixing hooks at the end parts of the tension meters 15 are formed in the connecting rods 14.
