Detailed Description
As shown in fig. 1, a tapered roller integrated measuring instrument of the present invention includes a frame 9 having a rectangular shape. The contact type electric sensor 1 distributed along the vertical direction is arranged at the top of the rack 9 and near the left end side surface. The upper portion centre gripping of contact electric sensor 1 is fixed on second centre gripping frock 2, and second centre gripping frock 2 slides the top that sets up and frame 9 to make its gauge head 102 stagger with first centre gripping frock 3 when changing the cone roller that awaits measuring, avoid damaging gauge head 102.

The side of the sliding plate 6 opposite to the frame 9 is provided with a first clamping tool 3 for supporting the tapered roller. After the tapered roller is placed in the first clamping tool 3, the driving device 7 drives the sliding plate 6 to slide in a reciprocating and linear mode, so that the measuring head 102 of the contact type electric sensor 1 scans the upper edge of the roll surface of the tapered roller from beginning to end, and various geometric precision parameters of the tapered roller are calculated by matching with a computer.
The first clamping fixture 3 in the invention comprises a seat plate 305 in an inverted triangle shape and a bearing platform 303 fixed on the seat plate 305. The seat plate 305 is used for connecting with the sliding plate 6, and the bearing platform 303 is used for supporting the tapered rollers.

As shown in fig. 1 and 3, the driving device 7 of the present invention includes a rotating shaft 704 rotatably disposed in a boss provided on the other side of the frame 9, an eccentric wheel 702 eccentrically fixed to the front end of the rotating shaft 704, a slip ring 703 cooperatively installed to the outer edge of the eccentric wheel 702, and a connecting rod 701. Holes for the connecting rod 791 to penetrate into the inner cavity of the frame 9 to be connected with the sliding plate 6 are formed on the side surface of the frame. One end of the connecting rod 701 is fixed with the slip ring 703, the other end is provided with a second shaft hole 709, a second pin shaft matched with the second shaft hole 709 is arranged at the center position of one side of the sliding plate 6 opposite to the first clamping tool 3, and the connecting rod 701 is hinged with the sliding plate 6 through the second pin shaft and the second pin hole.

For tapered rollers with different lengths, the stroke of the sliding plate 6 in a reciprocating manner can be adjusted so that the contact type electric sensor 1 just detects the value from one end of the tapered roller and the other end of the tapered roller in one reciprocating stroke of the tapered roller. In this embodiment, the reciprocating linear sliding travel of the sliding plate 6 is adjusted by an adjusting mechanism, as shown in fig. 2, the adjusting mechanism includes a shaft seat 11 for supporting the rotating shaft 704, a bar-shaped hole 10 formed on the frame 9 for sliding the shaft seat 11, and a travel adjusting screw 8. The strip-shaped holes 10 are distributed along the vertical direction, the stroke adjusting screw rod 8 is rotatably arranged in the strip-shaped holes 10 along the length direction of the strip-shaped holes 10, a threaded through hole 12 is formed in the shaft seat 11, the middle part of the stroke adjusting screw rod 8 is matched with the threaded through hole 12, two ends of the stroke adjusting screw rod 8 are rotatably arranged on the frame 9 at positions corresponding to two ends of the strip-shaped holes 10 respectively, and a limiting mechanism for preventing the stroke adjusting screw rod 8 from axially displacing is arranged. The upper end of the stroke adjusting screw rod 8 also extends out of the frame 9 so as to enable the stroke adjusting screw rod to be twisted to rotate by tools such as a spanner and drive the shaft seat 11 to move up and down in the rotating process. In the process of moving the shaft seat 11 up and down, the rotating shaft 704 moves synchronously, the distance between the rotating shaft 704 and the second pin shaft is changed, and the reciprocating sliding stroke of the sliding plate 6 can be adjusted through the change of the rotating shaft 704 and the second pin shaft Zhou Jianju.

The elastic transmission belt 707 can exert the same transmission function even when the distance between the rotating shaft 704 and the output shaft of the servo motor 706 is synchronously changed due to the adjustment of the rotating shaft 704 and the second pin Zhou Jianju. The sliding stroke adjustment amplitude of the sliding plate 6 is not too large because the length specification difference of the tapered rollers is smaller in actual production. The use of the elastic drive belt 707 can thus fully meet the drive requirements before and after adjustment.
When the geometric precision of the tapered roller is detected by the application, firstly, a standard tapered roller workpiece is placed on a city platform and is matched with a large end baffle 301 for positioning, a servo motor 706 is started to drive the standard tapered roller to reciprocate left and right along the horizontal direction, the standard tapered roller is enabled to receive scanning of a contact type electric sensor 1 from a large end to a small end in the reciprocating motion process, the angle and large end size data of the standard tapered roller are generated by a computer, and a measuring head 102 of the contact type electric sensor 1 is always contacted with the upper edge of a rolling surface of the standard tapered roller under the pushing action of a spring 101; and then the standard tapered roller is taken down and prevented from moving to the bearing platform 303, the servo motor 706 is started to drive the tapered roller to be tested to continue to reciprocate left and right along the horizontal direction, so that the tapered roller to be tested is also subjected to scanning of the contact type electric sensor 1 from the large end to the small end, the angle and the large end size of the tapered roller are measured and compared with the standard vertical of the standard tapered roller, and whether the tapered roller is in a specified tolerance range is judged. And synchronously completing the detection of the upper edge profile of the tapered roller rolling surface in the reciprocating motion process.
