Therefore, after the eccentric shaft is machined, the position precision, the eccentricity and the like of the eccentric shaft need to be detected, however, the eccentric shaft is difficult to accurately position in the detection process due to the fact that the eccentric shaft comprises the shaft body with two eccentric ends.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve the inconvenient, unsafe problem of eccentric shaft location among the prior art, provide a convenient to use, fix a position accurate eccentric shaft and detect location frock.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the eccentric shaft detecting and positioning tool comprises a bottom plate, wherein a positioning seat is fixed at one end of the bottom plate, supporting plates are arranged at two ends of the top surface of the positioning seat, a V-shaped groove is formed in the top surface of each supporting plate, a permanent magnet is fixed in the middle of the top surface of the positioning seat, a limiting seat is fixed at the other end of the bottom plate, and a reference limiting surface perpendicular to the bottom plate is arranged on the inner side of the limiting seat. The main shaft section on the eccentric shaft is positioned through the V-shaped grooves on the top surfaces of the two supporting plates, then the main shaft section is magnetically attracted through the permanent magnets, the eccentric section on the eccentric shaft is manually rotated, the eccentric section is rotated to be tangent to the reference limiting surface, the state is the positioning state of the eccentric shaft, and then the eccentric shaft is detected through the dial indicator. The positioning tool is simple in structure, convenient to use and accurate in positioning.

Preferably, a sliding groove is vertically distributed in the limiting seat, a sliding block is arranged in the sliding groove, a long groove hole communicated with the sliding groove is formed in the reference limiting surface, a horizontal lifting rod penetrating through the long groove hole is fixed on the inner side surface of the sliding block, a screw rod is vertically distributed in the center of the sliding block, the upper end of the screw rod penetrates through the top surface of the limiting seat and is rotatably connected with the limiting seat, the screw rod is in threaded connection with the sliding block, and an adjusting handle is arranged at the upper end of the screw rod. When the eccentric section is manually rotated, the eccentric section is difficult to rapidly and accurately rotate to a state of being tangent to the reference limiting surface, and the head is easily rotated by a slightly large hand force, so that the screw rod is driven to rotate by rotating the adjusting handle, the horizontal lifting rod is driven by the screw rod and the sliding block to drag the eccentric shaft section to lift and rotate, and the rotating speed of the eccentric shaft section can be accurately controlled; and the horizontal lifting rod plays a supporting role in the detection process to the eccentric section, and the position of the eccentric shaft is prevented from being changed due to the vibration of the external environment and the error touch of an operator on the eccentric shaft in the detection process.

Preferably, the adjusting handle is provided with anti-skid grains. The anti-skidding line can prevent skidding when making the manual rotation regulation handle.

Preferably, the inner side of the lower end of the limiting seat horizontally extends to form a connecting plate, and the connecting plate is connected with the bottom plate through bolts.

Therefore, the utility model discloses convenient to use, the accurate beneficial effect in location have.
