As a specific embodiment of the present invention, the round bar 7 is a hollow structure, the round bar 7 is made of polypropylene material, when the round bar 7 works, the round bar 7 moves back and forth under the indirect drive of the electromagnet 17, and if the mass of the round bar 7 is too large, the round bar 7 reacts slowly; the round bar 7 is of a hollow structure, so that the quality of the round bar 7 is reduced; the polypropylene material has low density and good hardness, so that the round rod 7 keeps light weight while ensuring the strength; and the counterfeiting of the polypropylene material is low, and the manufacturing cost is reduced.
As a specific embodiment of the invention, the length of the part of the round rod 7 higher than the rectangular groove 6 is 2-4 cm, the round rod 7 is used for measuring the hole center distance of the bearing bush cover, and when the round rod 7 is excessively extended in work, on one hand, material waste is caused, and on the other hand, the measurement error is increased; the length of the part, extending out of the rectangular groove 6, of the round rod 7 is set to be 2-4 cm, so that the round rod 7 keeps a small contact area when contacting with the side wall of the hole of the bearing bush cover, the edge position of the hole marked by the round rod 7 is more accurate, the situation of measurement errors caused by position deviation of the round rod 7 due to sundries in the hole or the skew hole is avoided, and the accuracy of measurement is further guaranteed.
During working, the detection tool of the bearing bush cover detects the position degrees of circular arcs, hole center distances, front end faces, rear end faces and the like of the bearing bush cover, the bearing bush cover is detected one by one in a manual detection mode at present, and the detection efficiency is low; through the arrangement of the conveying belt 3, the bearing bush covers can be placed on the conveying belt 3 and conveyed to the position of the detection tool, and then the mechanical arm 2 moves under the control of the controller and transfers the bearing bush covers to the position of the detection module one by one for detection; when the mechanical arm 2 moves the bearing bush cover to the detection module according to the correct direction and position, two round rods 7 on the detection table 4 are correspondingly inserted into two holes of the bearing bush cover, so that the bearing bush cover is limited; after the bearing bush cover is placed on the detection table 4, the controller controls the driving motor 8 to work, so that the driving motor 8 drives the rotating shaft 9 to rotate, and the first plate 10 and the second plate 11 which are installed on the rotating shaft 9 are driven to rotate; the rotating second plate 11 rotates by taking the rotating shaft 9 as a rotating center, so that the first pressure sensor 12 on the side wall of the second plate 11 is in contact with the bottom arc surface of the first pressure sensor 12 and moves on the arc surface; the first pressure sensor 12 is in contact with the arc surface of the bearing bush cover and then transmits a signal to the display screen 13, so that a pressure value curve is displayed on the display screen 13, and the pressure value curve represents the pressure variation condition between the first pressure sensor 12 and the arc surface; when the pressure between the first pressure sensor 12 and the arc surface is too large or too small, the size of the arc surface of the bearing bush cover is not in a standard range, the detected bearing bush cover belongs to an unqualified product, then the controller sends an alarm to the mechanical arm 2, so that the mechanical arm 2 takes down the unqualified bearing bush cover and puts the unqualified bearing bush cover into a defective product stacking area, and the qualified bearing bush cover is transferred to a qualified product stacking area by the mechanical arm 2; the detection of the bearing cap is changed into automation through the arrangement of the detection tool, so that a manual detection mode is replaced; the automatic detection mode is more efficient and accurate, the detection efficiency is improved, and meanwhile, the labor cost is reduced, so that the production cost is reduced.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
