In addition, the tie rod can also help absorb the vibration of the road and improve the driving comfort of the vehicle.

[0003] After the production and processing of the automobile tie rod is completed, it needs to be subjected to multiple tests, including hardness testing, displacement testing and visual testing, and it needs to be marked after the testing is completed to mark it and determine whether the tested automobile tie rod is a good product or a defective product. The traditional testing method is manual assisted operation, that is, the operator puts the automobile tie rod into the hardness tester, displacement tester and visual tester for testing in turn, and then marks it after testing. This method requires the automobile tie rod to be transported, consumes a lot of manpower, has low testing efficiency, and is prone to damage during transportation of the automobile tie rod, affecting the quality of the automobile tie rod.

DETAILED DESCRIPTION

[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0027] The present embodiment provides a pull rod continuous detection device, which can perform continuous and stable detection on the pull rod. Without human assistance, the pull rod can be continuously and multiple times detected and marked. The detection efficiency is higher, and time and labor are saved. There is no need for manual transportation of the pull rod, which avoids damage to the pull rod during transportation.

[0028] Combination Figures 1 to 3 As shown, the detection equipment of this embodiment includes a first transfer module 10, a first detection unit 20, a second transfer module 30, a second detection unit 40, a third transfer module 50, a third detection unit 60 and a marking machine 70. The first transfer module 10, the second transfer module 30 and the third transfer module 50 can transfer the tie rod in sections, while the first detection unit 20 performs hardness detection on the tie rod, the second detection unit 40 performs displacement detection on the tie rod, and the third detection unit 60 performs visual detection on the tie rod. The marking machine 70 can mark the tie rod according to the detection results after the detection is completed.

[0029] In this embodiment, the first transfer module 10, the second transfer module 30 and the third transfer module 50 are arranged in sequence. The first transfer module 10 is provided with a first clamping cylinder 11, which clamps the pull rod and moves under the drive of the first transfer module 10. The second transfer module 30 is provided with a rotating cylinder 31 and a second clamping cylinder 32, the second clamping cylinder 32 clamps the pull rod, and the rotating cylinder 31 drives the second clamping cylinder 32 to rotate. 31 moves under the drive of the second transfer module 30, and the third transfer module 50 is provided with a third clamping cylinder 51, which clamps the pull rod and moves under the drive of the third transfer module 50. The first clamping cylinder 11, the second clamping cylinder 32 and the third clamping cylinder 51 of this embodiment can all clamp the pull rod, and the second transfer module 30 is also provided with a rotating cylinder 31, which can rotate the second clamping cylinder 32 to detect the displacement of the pull rod.

[0030] Specifically, the first transfer module 10, the second transfer module 30 and the third transfer module 50 are connected in sequence. When the pull rod moves from the first transfer module 10 to the second transfer module 30, the second clamping cylinder 32 clamps the pull rod on the first clamping cylinder 11. When the pull rod moves from the second transfer module 30 to the third transfer module 50, the second clamping cylinder 32 places the pull rod on the clamping position of the third clamping cylinder 51, thereby realizing the position transfer of the pull rod.

[0031] Combination Figure 1 and Figure 3 As shown, the first detection part 20 is located within the transfer range of the first transfer module 10. The first detection part 20 includes a driving module 21 and a hardness meter 22 located at the piston rod end of the driving module 21. The driving module 21 drives the hardness meter 22 to contact the pull rod to perform a hardness test on the pull rod. Before the hardness test on the pull rod is performed, the pull rod is clamped by the first clamping cylinder 11 on the first transfer module 10. Under the driving action of the first transfer module 10, the pull rod moves to the detection position, and the driving module 21 drives the hardness meter 22 to contact the pull rod, and the hardness meter 22 can perform a hardness test on the pull rod.

[0032] like Figure 1As shown, the second detection part 40 is located within the transfer range of the second transfer module 30. The second detection part 40 includes two displacement sensors 41 that are arranged opposite to each other. The pull rod passes between the two displacement sensors 41 for displacement detection. In this embodiment, the spacing between the two displacement sensors 41 is 5cm-8cm. Before the displacement detection of the pull rod is performed, the second clamping cylinder 32 of the second transfer module 30 clamps the pull rod. Under the driving action of the second transfer module 30, the pull rod is moved to the detection position. The rotating cylinder 31 drives the second clamping cylinder 32 to rotate so that the position of the pull rod to be detected is between the two displacement sensors 41 for displacement detection.

[0033] like Figure 1 As shown, the third detection part 60 includes a detection camera 61 and a detection light source 62. Under the illumination of the detection light source 62, the detection camera 61 detects the tie rod. Before the visual inspection of the tie rod, the third clamping cylinder 51 of the third transfer module 50 clamps the tie rod. Under the driving action of the third transfer module 50, the tie rod is moved to the inspection position. With the cooperation of the detection camera 61 and the detection light source 62, the visual inspection of the tie rod is realized.

[0034] In this embodiment, the marking machine 70 is located after the third inspection unit 60. The marking machine 70 marks the rod after inspection. If the rod is inspected to be qualified, a qualified mark is marked. If the rod is inspected to be defective, a failed mark is marked.

[0035] In this embodiment, the detection equipment also includes a base plate 80, and the first transfer module 10, the first detection part 20, the second transfer module 30, the second detection part 40, the third transfer module 50, the third detection part 60 and the marking machine 70 are all arranged on the base plate 80, and a material unloading cavity 81 is arranged on the base plate 80, and the material unloading cavity 81 corresponds to the position of the third transfer module 50. The material unloading cavity 81 can unload the pull rods of qualified products, and can also unload the pull rods of defective products.

[0036] In actual use of the detection equipment of this embodiment, the pull rod is on the first clamping cylinder 11 of the first transfer module 10, and is transferred to the detection position under the driving action of the first transfer module 10. The first detection unit 20 performs a hardness test on the pull rod, and then the pull rod is clamped by the second clamping cylinder 32 of the second transfer module 30 and transferred to the detection position. The second detection unit 40 performs a displacement test on the pull rod. After the test is completed, the second clamping cylinder 32 places the pull rod on the third clamping cylinder 51, and the third transfer module 50 transfers the pull rod to the detection position. The third detection unit 60 performs a visual inspection on the pull rod. After the test is completed, the marking machine 70 marks the pull rod.

[0037] In summary, the detection equipment of this embodiment can perform continuous and stable detection on the pull rod, perform continuous multiple detections on the pull rod without human assistance, and perform marking processing. Its detection efficiency is higher, saving time and labor, and there is no need for manual transportation of the pull rod, avoiding damage to the pull rod during transportation.

[0038] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods.
