[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0045] like Figure 2-4 As shown, this utility model provides a side frame flaw detector for easy loading and unloading of bolsters, including a gantry drive mechanism 1 set at the workpiece inspection position; a support frame 2 connected to the gantry drive mechanism 1; and a clamp 3 set at the end of the gantry drive mechanism 1.

[0046] A flaw detection device for the workpiece is installed at the lower end of the aforementioned support frame 2. The flaw detection device includes a frame 4, a support platform 5, a clamping and rotating mechanism 6, and a coil moving mechanism 7 mounted on the frame 4.

[0047] The aforementioned support platform 5 is located on both sides of the frame 4. The aforementioned clamping and rotating mechanism 6 is installed on the support platform 5, and the two clamping and rotating mechanisms 6 are arranged opposite to each other. One of the clamping and rotating mechanisms 6 can be displaced relative to the other clamping and rotating mechanism 6 to adjust the clamping distance between the two.

[0048] The above-mentioned coil moving mechanism 7 is provided in two sets, and both are arranged inside the clamping and rotating mechanism 6. The two coil moving mechanisms 7 move synchronously towards or away from each other, and can move synchronously from both ends of the workpiece to the middle for flaw detection.

[0049] The aforementioned gantry drive mechanism 1 includes an X-axis drive member 11 mounted on the support frame 2, a Y-axis drive member 12 mounted on the X-axis drive member 11, and a Z-axis drive member 13 mounted on the Y-axis drive member 12. The aforementioned clamp 3 is mounted at the lower end of the Z-axis drive member 13.

[0050] The working principle and beneficial effects of the above embodiments are as follows:

[0051] The gantry drive mechanism 1 of this utility model drives the end clamp 3 to move flexibly in three-dimensional space through the coordinated action of the X-axis drive component 11, the Y-axis drive component 12 and the Z-axis drive component 13, so as to realize the gripping and placement of the workpiece of the rocker or side frame and complete the automated loading and unloading.

[0052] Based on the length of the workpiece to be inspected, the clamping distance between the two clamping and rotating mechanisms 6 is adjusted first. The workpiece is placed on the clamping and rotating mechanism 6 and positioned directly opposite the coil moving mechanism 7. The clamping and rotating mechanism 7 clamps the workpiece and drives it to rotate. The two coil moving mechanisms 7 move synchronously and move from both ends of the workpiece to the middle. Through the electromagnetic induction between the coil and the workpiece, defects such as cracks and pores on the surface and inside of the workpiece are detected.

[0053] The multi-dimensional drive design of the gantry drive mechanism 1 in the X, Y, and Z directions of this utility model enables the fixture 3 to flexibly cover the workpiece storage area and the flaw detection area, realize automated loading and unloading, reduce manual handling costs, and improve work efficiency.

[0054] The clamping and rotating mechanism 6, with its adjustable spacing design, can adapt to workpieces of different sizes on the bolster side frame, eliminating the need to change fixtures for specific workpieces and reducing equipment adaptation costs.

[0055] Two sets of coil moving mechanisms 7 synchronously detect flaws from both ends to the middle. With the workpiece rotation adjustment, they can cover the entire surface of the workpiece and complex parts, avoiding blind spots in the detection.

[0056] In one embodiment,

[0057] like Figure 5-6 As shown, one of the aforementioned support platforms 5 is fixed on the frame 4, and another support platform 5 is mounted on the frame 4 via a first driving component. The first driving component includes a lead screw rotatably mounted on the frame 4 and a lead screw seat rotatably mounted on the lead screw. The lead screw seat is connected to the aforementioned support platform 5, and a roller guide rail is installed between the support platform 5 and the frame 4. The roller guide rail serves as a guide to ensure that the support platform 5 moves smoothly along a preset trajectory during displacement. The aforementioned lead screw is driven to rotate by a fourth driving motor so that one of the aforementioned clamping and rotating mechanisms 6 can be displaced relative to the other clamping and rotating mechanism 6.

[0058] After the aforementioned fourth drive motor is started, it drives the lead screw on the frame 4 to rotate, which in turn drives the support platform 5 connected to the lead screw seat to move along the frame 4. As the non-fixed side support platform 5 moves, the clamping and rotating mechanism 6 installed on it moves closer to or further away from the fixed side clamping and rotating mechanism 6, thereby precisely adjusting the distance between the two.

[0059] In one embodiment,

[0060] like Figure 7-8As shown, the clamping and rotating mechanism 6 includes a clamping electrode 61, an extension shaft 62, a support frame 63, and a rotating component 64. The extension shaft 62 is connected to a second driving component 65 that drives its horizontal displacement. The clamping electrode 61 is installed at the front end of the extension shaft 62, and the shape of the clamping electrode 61 matches the end shape of the workpiece.

[0061] The aforementioned support bracket 63 is installed at the end of the protruding shaft 62 and placed at the lower end of the clamping electrode 61 to support the workpiece;

[0062] The aforementioned rotating component 64 includes a large gear mounted on the extension shaft 62, a small gear meshing with the large gear, and a reducer connected to and driving the small gear to rotate. The large gear drives the extension shaft 62, the support bracket 63, and the clamping electrode 61 to rotate.

[0063] The second driving component 65 drives the extension shaft 62 to move horizontally, which in turn moves the clamping electrode 61 at the front end. The shape of the clamping electrode 61 matches the end shape of the workpiece and can fit tightly against the end of the workpiece. The clamping electrodes 61 on both sides work together to clamp the workpiece laterally from both ends.

[0064] The support frame 63 lifts the end of the workpiece and forms a three-dimensional fixed structure with the lateral clamping of the clamping electrode 61, which can prevent the workpiece from sagging or shifting and improve the clamping stability of the workpiece.

[0065] When the rotating component 64 is started, the reducer drives the small gear to rotate, which in turn drives the large gear and the extension shaft 62 to rotate, thereby synchronously driving the workpiece supported on the support frame 63 and the clamping electrode 61 to rotate together; the clamping electrode 61 conducts current through an external power supply, and the current flows along the circumference of the workpiece, causing the workpiece to generate a circumferential magnetic field.

[0066] In one embodiment,

[0067] like Figure 9 As shown, the above-mentioned coil moving mechanism 7 includes a movable seat 71 slidably mounted on a linear guide rail, and a first cylinder 72 mounted on the frame 4 and driving the movable seat 71 to move along the linear guide rail. A coil 73 is mounted on the movable seat 71. The coil 73 has a circular cross-section and is hollow inside.

[0068] The two sets of coil moving mechanisms 7 move synchronously under the drive of the first cylinder 72. The two moving seats 71 drive the coils 73 to move from both ends of the workpiece to the middle. The coils 73 are connected to an external power source through wires. When magnetized, they generate an axial magnetic field. During the movement of the two coils 73, they can continuously magnetize the entire axial length of the workpiece, ensuring that a stable leakage magnetic field is generated at the longitudinal defect, with no magnetization dead angle.

[0069] The two sets of coil moving mechanisms 7 move synchronously from both ends to the middle. Compared with single-sided moving detection, the detection stroke can be shortened by half, which greatly improves the flaw detection efficiency.

[0070] In one embodiment,

[0071] The aforementioned support frame 2 includes two opposing portal frames 21, a crossbeam 22 installed between the two portal frames 21, and the aforementioned gantry drive mechanism 1 installed on the crossbeam 22. The crossbeam 22 and the portal frames 21 are locked together with bolts to form a stable overall frame structure.

[0072] In one embodiment,

[0073] like Figure 10 As shown, the X-axis drive member 11 includes a first rack 111 and a first linear guide 112 arranged along the length of the crossbeam 22, a first sliding seat 113 slidably mounted on the first linear guide 112, a first drive motor 114 mounted on the first sliding seat 113, and a first gear 115 meshing with the first rack 111 at the output end of the first drive motor 114.

[0074] After the first drive motor 114 starts, it drives the first gear 115 at the output end to rotate. The rotational motion of the first gear 115 is converted into the linear displacement of the first sliding seat 113 along the first linear rail 112, thereby realizing the lateral movement of the clamp 3 in the X direction.

[0075] The aforementioned Y-axis drive member 12 includes a second linear rail 121 slidably mounted on a first sliding seat 113 and arranged perpendicularly to the first linear rail 112, a second sliding seat 122 mounted on the second linear rail 121, a second rack 123 arranged along its length on one side of the second sliding seat 122, a second drive motor 124 mounted on the first sliding seat 113, and a second gear 125 meshing with the second rack 123 connected to the output end of the second drive motor 124.

[0076] After the second drive motor 124 starts, it drives the second gear 125 to rotate. The second gear 125 meshes with the second rack 123 on the second sliding seat 122, driving the second sliding seat 122 to make linear displacement along the second linear rail 121, thereby realizing the longitudinal movement of the clamp 3 in the Y direction.

[0077] The aforementioned Z-axis drive component 13 includes a fixed seat 131 mounted on one end of the second sliding seat 122. The fixed seat 131 has a hollow structure. A third linear guide 132 is slidably mounted in the inner cavity of the fixed seat 131. A third sliding seat 133 is fixed on the third linear guide 132. A third rack 134 is mounted on the third sliding seat 133 along its length direction. A third drive motor 135 is mounted on the outer end of the fixed seat 131. The output end of the third drive motor 135 is connected to a third gear that meshes with the third rack 134.

[0078] After the third drive motor 135 starts, it drives the third gear to rotate. The third gear meshes with the third rack 134 on the third sliding seat 133, driving the third sliding seat 133 to make a vertical linear displacement along the third linear rail 132 in the inner cavity of the fixed seat 131, thereby realizing the lifting and lowering action of the clamp 3 in the Z direction.

[0079] The three driving components are independent yet coordinated and controllable. The fixture 3 can be moved automatically and precisely by pre-setting the path through the program, thus avoiding positioning errors caused by manual operation.

[0080] In one embodiment,

[0081] For example Figure 4 As shown, the above-mentioned clamp 3 includes a clamping seat 31 installed at the lower end of the third sliding seat 133, grippers 32 slidably installed at the lower end of the clamping seat 31 and arranged opposite to each other, and a bidirectional cylinder installed at the lower end of the clamping seat 31 with its extension end connected to the two grippers 32, providing driving force for the opening and closing of the grippers. When the bidirectional cylinder extends, the two grippers 32 move towards each other to realize the clamping action of the workpiece. When the bidirectional cylinder retracts, the two grippers 32 move away from each other to complete the release action of the workpiece. The above-mentioned grippers 32 are widened and the widened design is adopted to increase the contact area with the workpiece and improve the gripping stability.

[0082] In one embodiment,

[0083] A liquid collection plate 8 is installed at the bottom of the frame 4 to collect the magnetic suspension liquid dripping from the surface of the workpiece during the flaw detection process. The liquid collection plate 8 is connected to a water pump, and the other end of the water pump is connected to a spraying mechanism to spray the magnetic suspension liquid onto the workpiece.

[0084] In summary:

[0085] This utility model provides a bolster side frame flaw detector that facilitates loading and unloading. The gantry drive mechanism drives the fixture to move flexibly in three-dimensional space through multi-dimensional drive in the X, Y, and Z directions, realizing fully automatic grabbing, transfer and placement of bolster or side frame workpieces from the storage area to the flaw detection area. No manual handling is required, which reduces labor costs and improves loading and unloading efficiency.

[0086] This utility model adjusts the distance between the two clamping and rotating mechanisms through the first driving component, which can adapt to workpieces of different lengths such as bolsters or side frames, and has wide adaptability; the shape of the clamping electrode matches the end of the workpiece, and together with the three-dimensional fixing design of the support frame, it can stably clamp the workpiece.
