The rotating part 30 is arranged in the first direction of the workbench 10, the rotating part 30 comprises a rotating rod 31 and a zeroing disc 32, and the rotating rod 31 is fixedly connected with the positioning part 20 and is used for driving the positioning part 20 and the workpiece 200 to rotate to a preset angle; the zeroing disc 32 is fixedly connected with one end of the rotating rod 31 and is used for displaying the rotating angle of the positioning piece 20. The dial indicator 40 is arranged on the second direction of the workbench 10, and the dial indicator 40 can abut against the workpiece 200 which rotates to a preset angle so as to obtain the detection data of the workpiece 200.
In this embodiment, the first direction is an X direction, and the second direction is a Y direction.
The table 10 has a substantially rectangular plate shape.
The positioning member 20 includes a jig 21, a cover plate 22 for fixing the workpiece 200, a fastening screw 23, and a handle 24. The jig 21 is substantially plate-shaped and is used for placing the workpiece 200. The cover plate 22 covers the jig 21. The fastening screw 23 penetrates the cover plate 22 and is connected to the jig 21 for fastening the cover plate 22. The handle 24 is disposed on the cover plate 22 to facilitate the removal of the cover plate 22 covering the jig 21.
The rotation member 30 further includes a first support plate 33, a second support plate 34, and a hand wheel 35. A first support plate 33 and a second support plate 34 are each arranged in a first orientation on the table 10 and on opposite sides of the positioning member 20 for supporting the lever 31. The other end of the rotating rod 31 is fixedly connected with a hand wheel 35, the hand wheel 35 and the zeroing disc 32 are respectively arranged on two sides of the positioning part 20 in the first direction, and the hand wheel 35 can drive the rotating rod 31 to rotate so that the positioning part 20 and the workpiece 200 can rotate to a preset angle.
Further, the rotating member 30 also includes two bearings 36. Two bearings 36 are respectively disposed in the first support plate 33 and the second support plate 34 and connected to the rotating rod 31.
The number of the dial indicators 40 is two, and the two dial indicators 40 are oppositely arranged in the second direction of the workbench 10 and are located on two opposite sides of the positioning member 20.
A support block 41 is provided below the dial indicator 40. The dial indicator 40 is fixedly connected to the table 10 through a supporting block 41.
In this embodiment, the dial gauge 40 is a length measuring instrument that converts a generally linear displacement into a rotational movement of a pointer through a gear or a lever and then performs a reading on a dial. This dial gauge 40 includes gauge head, dial and drive mechanism, and its theory of operation is: when the measuring head makes a linear motion and abuts against the outer contour of the workpiece 200, the linear displacement of the measuring head is amplified by the transmission mechanism and converted into the rotation of the pointer on the dial, so that the size of the measured dimension is read.
The following steps of detecting the outer contour of the workpiece 200 by using the detection apparatus 100 of the present application to obtain the removal amount of the outer contour of the workpiece 200 are as follows:
s1: firstly, taking the cover plate 22 off the jig 21, placing the workpiece 200 to be processed on the jig 21, covering the cover plate 22 and fixing the workpiece by the fastening screws 23; in this implementation, the workpiece 200 has two states, one of which is the workpiece 200 to be machined, and the other of which is the machined workpiece 200. The workpiece 200 to be machined and the machined workpiece 200 are different machining states of the workpiece 200 body, and are not essentially different, so the reference numbers are unified and are limited by the workpiece to be machined and the machined workpiece.
S2: the workpiece 200 to be processed is precisely rotated to a preset angle through the cooperation of the rotating rod 31 and the zeroing disc 32;
s3, abutting the measuring head of the dial indicator 40 with the outer contour of the workpiece 200 to be processed which rotates to a preset angle to obtain the measuring data of the abutting position;
s4: repeating the step S2 and the step S3 for a plurality of times to obtain a plurality of sets of measurement data of different positions on the outer contour of the workpiece 200 to be processed;
s5: removing the workpiece 200 to be processed, and processing the workpiece 200;
s6: fixing the processed workpiece 200 on the jig 21 through the cover plate 22 and the fastening screw 23, and repeating the steps S2, S3 and S4 to obtain a plurality of sets of measurement data of different positions on the outer contour of the processed workpiece 200, wherein the measurement positions of the workpiece 200 to be processed and the unprocessed workpiece 200 are the same;
s7: the measurement data of the workpiece 200 to be machined is compared with the measurement data of the machined workpiece 200 to obtain the removal amount of the workpiece 200 to be machined. If the removal amount is preset as a standard, the machining process for the workpiece 200 is stopped; if the removal amount is smaller than the preset standard, the workpiece 200 is continuously processed until the workpiece meets the preset standard position; if the removal amount is greater than the predetermined standard, the workpiece 200 is over-machined and the workpiece 200 is scrapped.
The detection device 100 of the present application uses the cooperation of the rotating rod 31 and the zeroing disk 32 to precisely rotate the workpiece 200 to a preset angle, and enables the dial indicator 40 to measure the detection data of the workpiece 200 rotated to a plurality of preset angles, so as to obtain the removal amount of a plurality of positions on the workpiece 200. Compared with the prior art, the detection device 100 is simple, high in measurement accuracy and high in detection efficiency.
