the hydraulic tappet bottom surface taper gauge comprises a dial indicator, a positioning assembly and a guide assembly, wherein the positioning assembly comprises a positioning sleeve, the positioning sleeve is coaxially fixed on a fixing sleeve of the dial indicator, a positioning ring is arranged on the lower surface of the positioning sleeve, the guide assembly comprises a guide sleeve, the guide sleeve is coaxially fixed at the lower end of the positioning sleeve, and the inner diameter of the guide sleeve is the same as the outer diameter of the bottom end of the hydraulic tappet.
Furthermore, the positioning assembly further comprises a locking screw A, a threaded hole is formed in the side wall of the positioning sleeve, and the locking screw A is locked into the threaded hole and abuts against the outer wall of the fixing sleeve.
Furthermore, the guide assembly further comprises a locking screw B, a threaded hole is formed in the side wall of the guide sleeve, and the locking screw B is locked into the threaded hole and abuts against the outer wall of the lower end of the positioning sleeve.
Further, the locating ring is coaxial with the locating sleeve.
Furthermore, the cross section of the positioning ring is triangular.
The utility model has the advantages of it is following:
1. the utility model discloses simple structure examines utensil with low costs, and the practicality is high.
2. When the detection is carried out, the positioning sleeve is fixed on a fixing sleeve of the dial indicator, a standard plane block abuts against the positioning ring to zero the dial indicator, the guide sleeve is fixed at the lower end of the positioning sleeve, the bottom surface of the hydraulic tappet is plugged into the guide sleeve and abuts against the positioning ring, at the moment, the conical surface of the bottom surface of the hydraulic tappet automatically aligns to the indicator head of the dial indicator and pushes the indicator head, and when the indication number of the dial indicator is between 20 and 40 mu m, the conical surface meets the processing requirement, the operation is simple and convenient, and the detection precision is high.
