[0037] The utility model is further described below in conjunction with the embodiments shown in the accompanying drawings.

[0038] like Figure 1-4 As shown, it is a schematic diagram of the structure of the automatic detection equipment for iron bars of the utility model, which is used to complete various performance tests of iron bars, including detection structure 1, transfer structure 2 and conveying structure 3. Detection structure 1 is used to successively complete three performance tests of iron bars, including size detection at both ends of the iron bar, center distance detection of holes at both ends of the iron bar, and diameter detection of holes at both ends of the iron bar. Transfer structure 2 is used to clamp and transfer iron bars between various detection fixtures, and conveying structure 3 is used to convey qualified iron bars after detection.

[0039] like Figure 5 As shown, the testing structure 1 includes a testing platform 100, a first testing fixture, a second testing fixture and a third testing fixture. The first testing fixture, the second testing fixture and the third testing fixture are sequentially arranged on the top of the testing platform 100 to successively complete the three performance tests of the iron rod.

[0040] The first testing fixture is used to detect the dimensions of both ends of the iron rod, such as Figure 6 As shown, the first detection fixture includes a first bearing platform 101, a first bearing slot 102, a mounting slot 103, a laser sensor 104 and a pressing plate 105. The first bearing platform 101 is fixed to the top of the detection platform 100 by screw fastening, and the first bearing slot 102 is opened on the top of the first bearing platform 101 and matches the shape of the iron rod. The iron rod to be detected is clamped and placed in the first bearing slot 102 by the transfer structure 2.

[0041] The mounting groove 103 is opened at the top of the first supporting platform 101 and is located on both sides of the first supporting groove 102. The laser sensor 104 is installed in the mounting groove 103. When the transfer structure 2 places the iron rod in the first supporting groove 102 from top to bottom, the size detection of both ends of the iron rod is completed through the laser sensors 104 on both sides.

[0042] The pressing plate 105 is fixed to the top of the first supporting platform 101 by screw fastening. The pressing plate 105 is used to press the laser sensor 104 in the mounting groove 103 to prevent the laser sensor 104 from shaking and affecting the detection result.

[0043] The second detection fixture is used to detect the center distance of the holes at both ends of the iron rod, such as Figure 7-10 As shown, the second detection fixture includes a guide main board 106, a guide column 107, a first guide sub-plate 108, a second guide sub-plate 109, a positioning plate 110, a second positioning column 111, a second bearing platform 112, a second bearing groove 113, a second positioning hole 114, a second detection through hole 115, a detection plate 116, a detection column 117, a second abutment plate 118 and a second abutment groove 119. The guide main board 106 is fixed on the top of the detection platform 100, and the guide column 107 is inserted into the guide main board 106. The guide column 107 is used to guide the movement of the first guide sub-plate 108 and the second guide sub-plate 109 to improve the accuracy of subsequent detection results (the position of the guide column 107 on the guide main board 106 is fixed).

[0044] The first guide sub-plate 108 is sleeved on the guide column 107 and is located on one side of the guide main plate 106, and the second guide sub-plate 109 is sleeved on the guide column 107 and is located on the other side of the guide main plate 106. The outer sides of the first guide sub-plate 108 and the second guide sub-plate 109 are both connected to the moving cylinder, and the first guide sub-plate 108 and the second guide sub-plate 109 are driven inward by the moving cylinder to complete the positioning of the iron rod and the detection of the center distance. During this period, the first guide sub-plate 108 and the second guide sub-plate 109 are guided by the guide column 107 to improve the accuracy of positioning and the accuracy of the detection result.

[0045] The second support platform 112 is fixed to the top of the guide main board 106 by screw fastening, and the second support groove 113 is opened on the top of the second support platform 112. The transfer structure 2 clamps the iron rod after being inspected by the first inspection fixture and places it in the second support groove 113 for center distance inspection.

[0046] The positioning plate 110 is fixed on the top of the first guide sub-plate 108 and moves synchronously with the first guide sub-plate 108. There are two second positioning posts 111, which are respectively fixed on one side of the positioning plate 110 close to the second bearing platform 112. The second positioning hole 114 horizontally penetrates the second bearing platform 112 and is connected to the second bearing slot 113. When the center distance of the iron rod is detected, the first guide sub-plate 108 first drives the positioning plate 110 to move toward the side close to the second bearing platform 112, until the second positioning post 111 passes through the second positioning hole 114 and is inserted into the holes at both ends of the iron rod, so as to prevent the iron rod from tilting and swinging during the next step of detection.

[0047] The detection plate 116 is fixed on the top of the second guide sub-plate 109 and moves synchronously with the second guide sub-plate 109. There are two detection columns 117, which are respectively fixed on the side of the detection plate 116 close to the second bearing platform 112. The second detection through hole 115 horizontally penetrates the second bearing platform 112 and is connected to the second bearing groove 113. When the center distance of the iron rod is detected, the second positioning column 111 first completes the positioning of the iron rod, and then the second guide sub-plate 109 drives the detection plate 116 to move toward the side close to the second bearing platform 112, and the detection column 117 passes through the second detection through hole 115 and is inserted into the holes at both ends of the iron rod (if the detection column 117 can be inserted smoothly, it means that the center distance of the holes at both ends of the iron rod meets the processing requirements. If the detection column 117 cannot be inserted, it means that the center distance of the iron rod is too large or eccentric, and it is a defective product).

[0048] The second butt plate 118 is arranged on one side of the second supporting platform 112 by pushing the cylinder. The second butt plate 118 is provided with an arc-shaped second butt groove 119 on the side close to the iron rod. The second butt groove 119 matches the outer wall of the iron rod. When the center distance of the iron rod is detected, the second butt plate 118 is pushed toward the side close to the second supporting platform 112 by pushing the cylinder until the second butt groove 119 is against the outer wall of the iron rod. Under the dual action of the second positioning column 111 and the second butt plate 118, the iron rod is prevented from tilting and swinging during detection, thereby improving the accuracy of the center distance detection result.

[0049] The third testing fixture is used to test the diameter of the holes at both ends of the iron rod. Fig.11 , 12 As shown, the third inspection fixture includes a third bearing platform 120, a third bearing slot 121, a third positioning hole 122, a third inspection through hole 123, a third positioning column 124, an electronic plug gauge 125, a third abutment plate 126 and a third abutment slot 127. The third bearing platform 120 is fixed on the top of the inspection platform 100, the third bearing slot 121 is opened on the top of the third bearing platform 120, and the transfer structure 2 clamps and transfers the iron rod after inspection on the second inspection fixture to be placed in the third bearing slot 121.

[0050] The third positioning column 124 is arranged on one side of the third bearing platform 120 by a push cylinder, and the third positioning hole 122 horizontally penetrates the third bearing platform 120 and is connected with the third bearing groove 121. When the holes at both ends of the iron rod are inspected, the third positioning column 124 is first driven inward by the push cylinder until the third positioning column 124 passes through the third positioning hole 122 and is inserted into the hole at one end of the iron rod, thereby completing the positioning of the iron rod and preventing the iron rod from tilting and swinging.

[0051] The electronic plug gauge 125 is arranged on the other side of the third bearing platform 120 by pushing the cylinder, and the third detection through hole 123 horizontally penetrates the third bearing platform 120 and is connected with the third bearing groove 121. The electronic plug gauge 125 is driven by the pushing cylinder to move inward to the hole at one end of the iron rod, thereby completing the diameter detection of the hole.

[0052] A third abutment plate 126 is also provided on one side of the third supporting platform 120, and a third abutment groove 127 matching with the outer wall of the iron rod is provided on the inner side of the third abutment plate 126. The third abutment plate 126 has the same function as the second abutment plate 118. During detection, the third abutment plate 126 abuts against the outer wall of the iron rod to prevent the iron rod from tilting and swinging.

[0053] like Figure 5 As shown, the third detection device has two groups, which respectively detect the diameters of the holes at both ends of the iron rod.

[0054] The transfer structure 2 is fixed on the test bench 100 and is used to clamp and transfer the iron rod between the test jigs. The transfer structure 2 includes a gantry 201, a linear slide 202, a linear slide rail 203, a linear slider 204, a moving plate 205, a lifting slide rail 206, a lifting slider 207, a lifting cylinder 208, a lifting plate 209, a connecting plate 214 and a clamping unit. The gantry 201 is fixed on the top of the test bench 100 and is set above the first test jig, the second test jig and the third test jig.

[0055] The linear slide 202 is fixed on the top of the gantry 201, and there are multiple moving plates 205, which are slidably mounted on the gantry 201 through the linear slide rails 203 and the linear sliders 204. Every two adjacent moving plates 205 are connected by a connecting plate 214. When the linear slide 202 drives one of the moving plates 205 to move, the connecting plate 214 drives the remaining moving plates 205 to move synchronously.

[0056] The lifting cylinder 208 is fixed on the top of the moving plate 205, and the lifting plate 209 is connected to the lifting cylinder 208, and the lifting plate 209 is driven to move up and down by the lifting cylinder 208. A lifting rail 206 and a lifting slider 207 are arranged between the lifting plate 209 and the moving plate 205 to ensure the stability of the lifting movement of the lifting plate 209.

[0057] There are multiple groups of clamping units, which are fixed at intervals on the side of the lifting plate 209 away from the moving plate 205, and are used to clamp the iron bars on each detection fixture. Fig.13 As shown, the clamping unit includes a fixed plate 210, a finger cylinder 211, a clamping plate 212 and a clamping groove 213. The fixed plate 210 is fixed to one side of the lifting plate 209, the finger cylinder 211 is fixed to the bottom of the fixed plate 210, the clamping plate 212 is connected to the finger cylinder 211, and the clamping plate 212 is driven by the finger cylinder 211 to move to clamp the iron rod.

[0058] The clamping groove 213 is formed on the inner side of the clamping plate 212 and is in a V-shape. When clamping the iron rod, the iron rod can be clamped in the center, thereby ensuring the accuracy of the transfer position of the iron rod.

The conveying structure 3 includes a conveying frame 301, a conveying roller 302 and a conveying belt 303. The conveying frame 301 is fixed on the top of the inspection platform 100. There are two conveying rollers 302, which are rotatably mounted on the conveying frame 301. The conveying belt 303 is wound around the conveying roller 302, and the rotation of the conveying roller 302 drives the conveying belt 303 to rotate, thereby completing the conveying of the iron bars (the material of the conveying belt 303 is rubber, and when conveying the iron bars, the surface of the iron bars is avoided to be scratched).

[0060] The working principle of the automatic detection equipment for iron rods of the utility model is as follows:

[0061] First, the transfer structure 2 clamps the iron rod and places it on the first detection jig. After the first detection jig completes the size detection of the two ends of the iron rod, the transfer structure 2 clamps the iron rod to the second detection jig, and the second detection jig completes the center distance detection of the holes at both ends of the iron rod. After the detection is completed, the transfer structure 2 clamps the iron rod to the third detection jig, and the third detection jig completes the diameter detection of the holes at both ends of the iron rod.
