DETAILED DESCRIPTION
[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0018] See also Figure 1-Figure 3The utility model provides a technical solution: a cover press-fit depth gauge, including a calibration device 1, a jacket 8, a measuring head 7, a dial indicator protective cover seat sleeve 12 and a dial indicator 13. The calibration device 1 is composed of an upper seat 2 and a base 3 combined by reinforcing bolts, and a calibration press-fit groove 4 is opened at the upper end of the upper seat 2. An inner sleeve 9 is arranged inside the jacket 8, a spring seat 11 is installed at the upper end of the inner sleeve 9, and a spring 10 is installed at the lower end of the spring seat 11. A bracket 21 is installed outside the jacket 8, and a fixing plate 2 is fixed to the left and right sides of the rear end of the bracket 21 by bolts 19 and nuts 20. 2. The measuring head 7 is slidably installed in the inner sleeve 9, and its upper end is sleeved in the spring 10 and the spring seat 11. The upper end of the outer sleeve 8 is installed with a dial indicator protective cover seat sleeve 12 through a thrust seat 17 and a set screw 18. The inner side of the dial indicator protective cover seat sleeve 12 is installed with a dial indicator protective cover seat 14. The inner side of the dial indicator protective cover seat 14 is installed with a dial indicator rod protective sleeve 16. The lower end of the dial indicator 13 is provided with a dial indicator rod. This design solves the problem that when the original cover press-fitting depth is detected, the depth vernier caliper is used for measurement, which has low efficiency and poor accuracy, and has high technical requirements for the operator.
[0019] As the first embodiment of the utility model: a cover 5 is provided at the lower end of the measuring head 7, and a press-fit hole 6 is provided on the upper surface of the cover 5. The calibration device 1 is located below the cover 5. Through the added calibration device 1, the dial indicator 13 can be calibrated through the calibration press-fit groove 4 and the measuring head 7. A dial indicator protection cover 15 is installed at the rear end of the dial indicator protection cover seat 14. The added dial indicator protection cover 15 can shield and protect the rear side of the dial indicator 13. The lower end of the dial indicator rod passes through the dial indicator rod protection cover 16 to abut against the measuring head 7. A pin hole is provided through the lower side of the front end of the outer sleeve 8 and the inner sleeve 9. A pin is provided through the lower side of the front end of the measuring head 7, and the pin and the pin hole are clearance-matched. Through the clearance-matched between the added pin and the pin hole, the measuring head 7 can be limited and prevented from rotating.
[0020] As the second embodiment of the utility model: the device is used in two steps as a whole. The first step is calibration: align the measuring head 7 of the gauge with the calibration device 1 (at this time, the cover 5 is not under the measuring head 7), so that the end face of the outer sleeve 8 fits with the end face of the calibration press-fitting groove 4. At this time, the measuring head 7 passes through the calibration press-fitting groove 4 and contacts the upper end face of the base, so that the measuring head 7 overcomes the elastic force of the spring 10, and the dial indicator 13 is compressed to a certain extent through the dial indicator rod. At this time, the dial indicator reading is reset to zero.
[0021] The second step of measurement: align the measuring head 7 of the inspection fixture with the press-fitting hole 6 on the upper side of the blind cover 5, so that the end face of the outer sleeve 8 fits with the end face of the blind cover 5, and the measuring head 7 contacts the blind cover 5 to overcome the elastic force of the spring 10, and the dial indicator rod makes the dial indicator 13 have a certain amount of compression to achieve the dial indicator reading. At this time, the reading difference of the dial indicator 13 is the difference between the press-fitting depth of the blind cover 5 and the nominal value of the press-fitting.
[0022] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model.
